abstract = {Parallel kinematic machines (PKMs) are a class of robots that have long been recognized for their higher stiffness and high payload-to-weight ratio and precision compared to their serial counterparts [1,2]. Their applications are suitable in various areas such as high-speed machining, medical robotics, and space. Despite their advantages and widespread applications, PKMs suffer from various inherent challenges in design and control owing to complexities in kinematics, limited workspaces, and intricate singularity conditions [3]. Recent industrial developments and research work have focused on improving modeling techniques, the analysis of singular configurations, and reconfigurable architecture. Significant attention has been paid to domains such as the optimization of workspaces [4], the singularity avoidance approach [5], robust design procedures [6], and the integration of compliant components for PKM structures [7] in order to meet evolving application demands. However, several theoretical and practical aspects remain underexplored. For example, cuspidal configurations whereby a robot can transition between multiple inverse kinematic solutions without encountering singularities remain less documented [8,9]. Another interesting phenomenon includes self-motion conditions where the end-effector exhibits mobility even when all actuators are locked, thereby posing design challenges and difficulties in control [10,11]. Furthermore, emerging topics such as modular PKM architectures [12], dynamic performance evaluation [13], and control-aware design optimization [14] continue to attract the attention of the research community, especially for high-precision applications under uncertain or varying load conditions. The following Special Issue features eight articles in the field of PKMs and their potential applications to meet the present era's growing industrial demands.

In paper [15], the authors propose an approach for the 3D modeling of spatial manipulators using Maple 2023 software. This approach enables the creation of three-dimensional computer models of manipulators with clear visual representation of links, cross sections, kinematic pairs, and loads, differing in structure and degrees of freedom, while ensuring a comprehensive view from spatial perspectives. Using the Denavit-Hartenberg method for motion control of 3D models and the recursive Newton-Euler algorithm for calculating distributed dynamic loads, algorithms were developed for generating distribution diagrams of all dynamic loads in each link of a moving manipulator. This approach proves vital, especially during the design of new, innovative manipulators.

In paper [16], the author proposes a computationally efficient approach for dimensional synthesis using multi-objective particle swarm optimization with hierarchical constraints. The approach demonstrates the broad applicability of combined structural and dimensional synthesis for symmetric parallel robots with rigid links and serial-kinematic leg chains. The approach also allows for extension as an open-source MATLAB toolbox 2024b.

In paper [17], the authors present the design and analysis of a novel three-degrees-of-freedom parallel robot with self-sensing Nitinol actuators. The method is a continuation of a previous work and was extended to a 20 mm actuator length. The manipulator was realized, and the control strategy was validated experimentally. The work highlights the importance of self-sensing Nitinol actuators for the design of small parallel manipulators.

In paper [18], the authors propose a flexible surgical stapler mechanism for laparoscopic rectal cancer surgery. By performing workspace analysis and synthesizing kinematic equations, precise control of the mechanism was possible during surgical procedures in the rectal region. The singularities were also examined, considering the influential eyelet friction parameter. A preliminary design was presented, which facilitates the identification of the friction parameter.

In paper [19], the authors propose a neural network model to approximate the task time function of a generic multi-DOF robot. The method proposed a uniform interface that can be adapted to generic robots and tasks. The results presented an accurate model with evaluation times compatible with real-time process optimization.

In paper [20], the authors present the analysis of a spherical parallel mechanism of type 3-SPS-U. The usual singularity approach involves using Euler angles. However, this method is computationally expensive, especially when working with stacked models. Using the Tilt and Torsion approach, the singularity analysis was carried out successfully, which also enabled the work to be extended for stacked models. An experimental platform also aided in validating the approach.

In paper [21], the authors present a novel walking hybrid-kinematics robot that can be reconfigured to have three, five, or six degrees of freedom. A symmetric 3PRPR/3PRRR parallel manipulator with three translational DOFs was used to perform machining tasks. A serial module with two rotational DOFs was added to the 3T parallel mechanism to provide five DOFs. Similarly, a parallel 3SPR or 3SU mechanism can also be combined with the 3T parallel mechanism to provide six DOFs. The mobility, pose, kinematics, differential kinematics, singularities, and workspace of the parallel configuration are discussed in detail. The analysis showed that by making the moving platform of 3SPR or 3SU smaller than the base, the singularities can be easily avoided.

Lastly, in paper [22], the authors present a detailed review covering the fields of rehabilitation, assistive technologies, and humanoid robots. The authors focus on the study of parallel robots designed for human body joints with three degrees of freedom, particularly the neck, shoulder, wrist, hip, and ankle. The review authors discuss the timeline and advancements of parallel robots, focusing on technology readiness levels (TRLs), degrees of freedom, kinematic structure, workspace analysis, performance evaluation methods, and material selection for the design.

abstract = {The Gaza Strip is facing a surge in paediatric meningitis cases amid total health system collapse. Since October, 2023, prolonged military assault and blockade have destroyed health, water, and sanitation infrastructure. As of July, 2025, the UN reports that at least 1·9 million people?approximately 90% of the population in the Gaza Strip?have been displaced by the ongoing war and are now living in overcrowded and unsanitary shelters.1 Many have been forced to flee multiple times, with some displaced ten times or more. The repeated displacement orders issued by Israeli forces following the collapse of the ceasefire have driven even more people to flee in search of safety.1 This environment has enabled the rapid spread of meningitis, especially among children.

At Nasser Medical Complex in Khan Younis (Gaza Strip, occupied Palestinian territory), more than 40 children have been admitted with suspected or confirmed meningitis.2 Physicians report severe shortages of antibiotics and cerebrospinal fluid kits, forcing empirical treatment and unsanitary procedures. Children present with high fevers, neck stiffness, vomiting, and seizures, yet are treated on floors, often without electricity or sterile equipment.2

Underlying this outbreak is a broader public health emergency. Displaced infants have scarce access to clean water, nutrition, and maternal care.3 Many mothers are malnourished and unable to breastfeed; formula and nappies are largely unavailable. In one case, a 1-month-old baby was diagnosed with meningitis after living for weeks in unsanitary conditions, without proper nutrition or hygiene supplies.3

The spread of meningitis in Gaza reflects the collapse of core public health protections. Hospitals are non-functional, staff are overwhelmed, and basic supplies are cut off.4 This outbreak, similar to those seen in conflict-affected settings such as South Sudan5 or Syria6, underscores the devastating impact of displacement and water, sanitation, and hygiene failures; however, Gaza's isolation and long-term siege make the crisis even more acute.7

Immediate international action is required. Priorities include reaching an immediate ceasefire; provision of antibiotics, vaccines, and diagnostic tools; restoration of water, sanitation, and hygiene services; establishment of humanitarian corridors; protection of health facilities; and support for disease surveillance. Without urgent intervention, more children will die from preventable illness. We call on the global health community to act now?to protect Gaza's children from further suffering and irreversible harm.},

Recent developments in big data availability and more powerful analytical tools have increased the potential value of BI&A systems. However, academic and practitioner-oriented research suggests that the potential success of BI&A systems has not yet been fully realized by most organizations. Existing studies have attempted to evaluate the effectiveness and success of BI&A systems by proposing various success measures. However, these studies have generated inconsistent results, limiting the ability to compare and generalize the findings. Therefore, this study takes a step forward by proposing an updated, comprehensive, and consolidated set of success measures for this unique class of information systems. Using a systematic literature review approach, this study examined and synthesized BI&A systems success measures across 173 past studies using the DeLone & McLean IS success framework. Findings revealed success measures such as ease of use, information accuracy, and financial performance that are consistently applied to the measurement of BI&A systems, and importantly, other recommended measures such as system features, presentation format, and decision-making performance that are uniquely important to BI&A systems but infrequently applied. Finally, a comprehensive set of BI&A success measures is proposed for future empirical research studies and practitioner use.},

abstract = {In recent years, the surge in data-driven applications across various domains has spurred heightened interest in semi-supervised learning applied to graphs. This surge is attributed to the ubiquitous presence of graph data structures in real-world contexts, such as social networks' interpersonal relationships, recommender systems' user behavior graphs, and bioinformatics' molecular interaction networks. However, for certain data types like images, not only is there a dearth of explicit graph structure, but also the existence of multiple view description methods complicates matters further. The intricacies of multi-view data pose challenges in directly applying traditional semi-supervised learning techniques to graphs. Consequently, researchers have begun exploring the fusion of semi-supervised learning with deep learning to leverage its wealth of information and enhance model efficacy. Effectively amalgamating graph structures with multi-view data remains a challenging problem necessitating further research. This paper introduces the Linear projection Fused Graph-based Semi-supervised Classification (LFGSC) method tailored for multi-view data, building upon the Graph Convolutional Network (GCN) architecture. Firstly, for each view, we leverage a semi-supervised approach that provides the concurrent estimation of the corresponding graph and the flexible linear data representations in a low-dimensional feature space. Subsequently, an adaptive and unified graph is generated, followed by the utilization of a fully connected network to fuse the projected features further and reduce dimensionality. Finally, the fused features and graph are inputted into a GCN to conduct semi-supervised classification. During training, the model incorporates cross-entropy loss, manifold regularization loss, graph auto-encoder loss, and supervised contrastive loss. Leveraging linear transformation significantly diminishes the input feature dimensions for GCN, thereby achieving high accuracy while substantially reducing computational overhead. Furthermore, experimental results conducted on various bench-marked multi-view image datasets demonstrate the superiority of LFGSC over existing semi-supervised learning methods for multi-view scenarios.

abstract = {Dental prostheses have significantly evolved due to advances in Computer Aided Design and Manufacturing (CAD/CAM) technology. CAD/CAM systems provide a variety of biomaterials like ceramics, Polymer-Infiltrated Ceramic Network (PICN), and composites, which are preferred for their mechanical and aesthetic properties. However, ceramics, despite their popularity, are brittle and prone to chipping during the machining process, impacting the prosthesis's clinical functions, aesthetics, biological integrity, and mechanical performance.

Chipping, especially at thin cervical margin, can cause visible defects, poor sealing, and bacterial growth, reducing prosthesis lifespan. Milling factors influence cervical margin integrity.

Chipping assessment involves understanding biomaterial mechanical and machinability characteristics regarding dimensional characterization of milled prosthesis shape. Thus, different type of metrics, based on biomaterial properties or dimensional measurement can be used to assess chipping phenomenon for milled dental ceramics. These metrics are both, based on experimental studies found in literature, and proposed by this paper authors to fill the existing lacks.

The brittleness index, based on the ratio between hardness and fracture toughness, predicts susceptibility to chipping after milling. Unidirectional dimensional metrics like the Chipping Factor and weighted Chipping Factor characterize the chipping ratio of the cervical margin. Advanced 2D and 3D metrics, including chip projected area, total weighted chip projected area, and Surface Aspect Ratio, offer more detailed assessments. 3D analysis involves comparing scanned files with CAD models to compute chipped volumes. The aim of this paper is to propose a critical analysis from an engineering viewpoint on metrics used to assess cervical margin integrity for milled dental prosthesis.},

abstract = {When dealing with short-life cycle products, small and medium-sized enterprises (SMEs) commonly confront challenges stemming from limited local censored demand data. This often leads to a lack of comprehensive understanding of demand distribution and can result in suboptimal order decisions. To address this issue, we introduce a data-driven newsvendor framework that combines a novel cost-driven data correction procedure with distributionally robust optimization (CDDC-DRO). With cost minimization objectives, the proposed procedure integrates local censored demand data and external demand information to adaptively generate high-value improved censored datasets, while circumventing reliance on static correlations. Furthermore, we consider the granularities of external demand information and propose three DRO-based data correction strategies to effectively reduce demand censoring. Tests on both simulated and actual data indicate that the CDDC-DRO procedure adaptively corrects censored data based on demand characteristics and cost structures, thereby eliminating significant errors induced by demand censoring and improving the precision and robustness of order decisions. The correction degree of the improved censored datasets dynamically depends on cost structure. A high degree of data correction is employed under high critical ratios, whereas a minimal correction degree is applied under low critical ratios. In response to the significant negative impacts of demand censoring, SMEs prefer to implement the DRO-based data correction strategy with finer-grained external demand information. This strategy enhances correction capabilities while minimizing variations in decision accuracy. Even when finer-grained external demand information is unavailable, SMEs are able to make well-informed order decisions using the DRO-based data correction strategy with local censored demand data.},

abstract = {In machine learning, deep metric learning from original data is essential, with supervised contrastive learning being a notable approach. This method aims to form a deep feature space where similar samples from the same class are clustered together, while dissimilar samples from different classes are separated. However, a common limitation of contrastive learning methods is that they utilize the entire feature space for data embedding and often neglect the within-class variability. To overcome this limitation, we propose a novel supervised contrastive learning method that decomposes deep features into two distinct components: common features, which encapsulate the essential, class-defining characteristics, and style features, which capture the within-class variability and nuanced differences. Additionally, we enhance this approach by introducing an overlapping field that synergistically integrates elements from both feature spaces, enabling a more comprehensive and robust feature representation. Our experiments with different image datasets and deep encoders, including CNNs and transformers, show that our approach outperforms traditional single-feature contrastive methods. On the CIFAR100 and PASCAL VOC databases, traditional supervised contrastive learning achieved accuracy rates of 75.5% and 51.41%, respectively, while our method improved them to 77.81% and 59.38%, respectively. We present an algorithm for deep contrastive learning that utilizes two feature spaces: one for encoding common class features and another for capturing within-class variability. This is achieved by partitioning the features of the last layer of the encoder into (i) a common field and (ii) a style field. Our loss function contrasts the common features while summarizing the style features within the same class so that the style field can capture the intra-class variability.},

abstract = {The field of bio-inspired approaches (also known as biomimetics or biomimicry) is

a design approach whereby a product or process is inspired by elements of nature, such

as plants or animals. Bio-inspired approaches serve as inspiration and motivation for

many engineers and designers in their efforts to identify unexpected solutions to problems.

These approaches have resulted in significant innovations in the aerospace, marine, and

automotive industries. The domains of bio-inspiration and bio-mimetics have also been

the focus of several studies in the domain of robotics. There are several examples of their

use in the literature, including their implementation in snake-type robots for underwater

inspection or in worm-type systems for industrial pipeline inspections. This Special Issue

presents the recent advancements in the domain of bio-inspired robotics and their potential

applications in industry. This will help researchers from all communities to understand

the relevance of bio-inspiration in robotics and will serve as a platform for the application

of these cutting-edge approaches in other fields. This Special Issue comprises 11 articles

in the domain of biomimetics, examining the study of this concept and its application in

robotic systems.

In paper [1], the authors exploit the locomotion of bio-primates, which include contin-

uous brachiation and ricochetal brachiation. The design mimics the transverse movements

of sports climbers holding onto horizontal wall ledges. Based on a two-hand release de-

sign, a novel transverse ricochetal brachiation mechanism exploits inertial energy storage

to enhance moving distance. Experimental prototypes helped to predict the success of

subsequent locomotion cycles.

In paper [2 ], the authors present an angle sensor based on step-index profile plastic

optical fiber (SI-POF), which was cost-effective and durable. The performance of the POF

sensor was evaluated by measuring sensitivity and resolution in order to verify its reliability

under extreme conditions, especially underwater. This study is vital to the development of

biomimetic robot industry where existing sensors are difficult to deploy.

Paper [ 3] presents a novel whisker-sensing disk designed for 3D mapping in unstruc-

tured environments. The modeling is performed based on analytical and data-driven

approaches to predict rotation angles based on magnetic field measurements. Experiments

were conducted to validate the modeling, and the results highlight the effectiveness of 3D

mapping in complex environments for robotic platforms in the future.

Paper [ 4 ] presents a review of robot control in spaces with low material and structural

stiffness, which is usually challenging. Based on an in-depth review of scientific articles, the

conclusions of this study indicate three top performing methods. The methods are based

on minimizing control effort usage, tracking error mean, and tracking error deviation with

some improvements in performance measures.

In paper [5 ], the authors propose the use of impedance control for the regulation of

dynamic response of pneumatic soft robots, an approach already in existence for rigid

robots. A non-linear discrete sliding mode impedance controller is formulated to control

soft pneumatic robots. The controller does not require the manual tuning of parameters

and can automatically calculate them based on impedance value. Experiments showed that

the proposed controller can effectively limit the amplitude of undesirable vibrations.

Paper [6] presents a distributed model predictive controller based on leader-follower

approach for addressing the collaborative transportation control issue of dual humanoid

robots. Network latency issue is a prominent problem due to unstable network conditions

that affects the consistency of collaboration. A socket communication was constructed

to resolve the latency issue. A distributed model predictive control helped consider

cumulative errors that lead to the enhanced position tracking accuracy of dual-robot

collaborative control.

In paper [ 7], the authors measured hand movements in stroke patients using Me-

diaPipe and Fahrenheit to assess their criterion-related validity. Consistent results were

observed in peak angle and velocity comparisons across severity stages. The study high-

lighted the importance of MediaPipe in paralysis estimation.

Paper [8 ] presents important research on malfunctioning joints that lead to a high

degree of compactness, eventually resulting in benefits such as low mass, low moment

of inertia, and low drag. It was found that this multifunctionality was achieved through

various means, such as multiple degrees of freedom, multifunctioning parts, over-actuation,

and reconfiguration. This research suggests that the agility of robots could be improved

using multifunctioning to reduce the size and mass of robotic joints.

In paper [9 ], the authors present a motion prediction model developed using con-

volutional neural networks (CNNs) for the efficient identification of motion types at the

initial states. A multi-axial robotic arm integrated with a motion identification platform

was developed to interact with humans by emulating their movements. A control strat-

egy for addressing non-linearities and cross-coupled dynamics of the robotic system was

applied. The results show that the robotic arm was able to achieve adequate controlled

outcomes, thereby validating the feasibility of such an interactive robotic system in effective

bio-inspired motion emulation.

Paper [ 10 ] presents a novel bionic amphibious robot, AmphiFinbot-II. The robot's

swimming and walking components involved a compound drive mechanism that allows

for the simultaneous control of the rotation of the track and the wave-like motion of

the undulating fin. The performance was tested via different motion patterns through

computational fluid dynamics simulations. Experiments were also conducted on land and

underwater, and the results were consistent with the simulation. The findings showed that

the proposed robot possesses excellent amphibious motion capabilities through a unified

control approach.

Finally, paper [ 11 ] presents the empirical kinematic control and data-driven modeling

of a soft swimming robot. The robot consists of six serial connected segments that can bend

individually using segmental pneumatic artificial muscles. Experiments were conducted to

gather position and velocity of spatially digitized points using Qualisys Tracking Manager

1.6.0.1. Through offline analysis, a new complex variable algorithm was proposed to extract

a linear approximative model. The proposed algorithm helped in extracting linear and

chaotic modes and aided in linearizing the overall system dynamics.

Experimental evaluations on the MSVD and VATEX datasets demonstrate that the TimeSformer-GPT-2 architecture significantly outperforms baseline models, particularly in GPU settings, achieving top results across BLEU, METEOR, ROUGE-L, and CIDEr metrics. This superiority is attributed to its capacity to model spatiotem-poral dependencies and generate contextually rich language. Designed for real-time operation, the system is also suitable for low-resource devices, enabling impactful applications such as assistive tools for the visually impaired and intelligent video indexing. Despite high computational demands and sequence-length limitations, the system presents promising directions for future development, including multilingual captioning, multimodal audio-visual integration, and lightweight models like TinyGPT for enhanced portability.},

abstract = {Semi-supervised learning with a graph-based approach has become increasingly popular in machine learning, particularly when dealing with situations where labeling data is a costly process. Graph Convolution Networks (GCNs) have been widely employed in semi-supervised learning, primarily on graph-structured data like citations and social networks. However, there exists a significant gap in applying these methods to non-graph multi-view data, such as collections of images. To bridge this gap, we introduce a novel deep semi-supervised multi-view classification model tailored specifically for non-graph data. This model independently reconstructs individual graphs using a powerful semi-supervised approach and subsequently merges them adaptively into a unified consensus graph. The consensus graph feeds into a unified GCN framework incorporating a label smoothing constraint.

To assess the efficacy of the proposed model, experiments were conducted across seven multi-view image datasets. Results demonstrate that this model excels in both the graph generation and semi-supervised classification phases, consistently outperforming classical GCNs and other existing semi-supervised multi-view classification approaches. 1},

abstract = {The goal of multi-view clustering is to partition unlabeled objects into disjoint clusters or groups using consistent and complementary information provided by the different features of the same object. Most existing methods perform this clustering task sequentially: Computation of the individual or consistent graph matrices, spectral embedding, and clustering. In this work, we present an approach that can overcome some of the limitations of previous multiview clustering methods. We introduce a single objective function whose minimization can jointly determine the consistent graph matrix for all views, the unified spectral data representation, the soft cluster indices, and the view weights. We present a constraint term that relates the cluster indices to the convolution of the consistent spectral data representations over the consistent graph. The method we present has two interesting features that are not simultaneously present in recent work. First, the cluster indices can be estimated directly without the need for an additional clustering step, which depends heavily on initialization. Second, the soft cluster indices are directly linked to the kernel representation of the features of the views. Moreover, our proposed method automatically determines the weights of each view, thus requiring fewer hyperparameters. A series of experiments have been conducted on real datasets. These demonstrate the efficiency of the proposed method, which compares favorably to many multi-view clustering methods.},

abstract = {Urban environments present significant challenges to commercial Global Navigation Satellite Systems (GNSS) receivers due to degraded satellite visibility and Non-line-of-sight (NLOS) receptions. Mitigating NLOS receptions for GNSS is essential, especially for safety-critical and reliability-critical location-based applications. Traditional physical error channel propagation modeling encountered bottlenecks since the NLOS and multipath errors cannot be modeled accurately in complex urban environments. Data-driven methods show significant potential for effectively classifying GNSS Line-of-sight (LOS) and NLOS. This paper proposes the CarNet - a generative Convolutional Neural Network (CNN)-based GNSS LOS/NLOS classifier by transforming multivariate time-series data into images. CarNet comprises two modules: an image generator and an image classifier. The image generator enriches and augments the original 1-dimension feature vector into 2-dimension feature maps and the image classifier uses an inception-based CNN to realize multi-scale feature extraction and classification. The proposed architecture is trained and tested on more than 6 h of real vehicle data collected in different challenging environments (about 1.6 million samples). A thorough benchmark is conducted, comparing CarNet against the existing mainstream Artificial Intelligence (AI) methods. The results with cross-validation on unseen data indicate that CarNet achieves the highest accuracy, i.e., 81.47% while maintaining the optimal balance between precision for both classes: 83.3% for LOS and 70.99% for NLOS. Finally, positioning accuracy is assessed using a reweighting strategy based on the LOS/NLOS information predicted by CarNet. The assessment of total datasets shows that CarNet weighting can achieve the best accuracy compared to the traditional weighting schemes based on signal-to-noise ratio or satellite elevation. CarNet shows strong potential for embedding into GNSS receivers to enhance positioning accuracy in complex urban environments, benefiting a wide range of location-based applications such as autonomous driving, emergency response, and urban logistics.},

The primary distinction lies in the construction of the consensus similarity graph. The first model directly reconstructs the

consensus graph from different views using a specialized objective function designed for flexible graph-based semi-supervised

classification. In contrast, the second model independently reconstructs individual graphs and subsequently adaptively merges

them into a unified consensus graph. Our experiments encompass various multiple-view image datasets. The results consis-

tently demonstrate the superior performance of our proposed approach compared to traditional fusion methods with GCNs. In

this research, we present two approaches for tackling semi-supervised classification challenges involving multiple views. One

method is named Semi-supervised Classification with a Unified Graph (SCUG), and the other is referred to as Semi-supervised

Classification with a Fused Graph (SC-Fused). Both methods share a common semi-supervised classification process, utilizing

the GCN framework and incorporating label smoothing. However, the key distinction lies in the construction of the similarity

This study seeks to fill this gap by employing a holistic approach to analyze the complexity and evolutionary characteristics of a representative CoPS industry, across macro-network, meso-module, and micro-motif levels. Utilizing global patent data from 2001 to 2020 pertaining to chip manufacturing, our analysis identifies distinct collaborative patterns across the macro, meso, and micro levels within GICNs. At the macro level, there is a discernible shift towards a distributed structure, epitomized by a ?big center, multi-centers, decentralization? trend. The meso level exhibits a progression towards a ?loosely coupled? configuration of technical sub-modules, reflecting a specialized division of labor. Notably, the micro level demonstrates a significant centralization in collaborative innovation, with enterprises playing a pivotal role. This investigation provides an exhaustive empirical examination of GICNs within the CoPS industry and offers novel insights into the evolution of such networks. Furthermore, it furnishes actionable recommendations for policymakers and engineering managers seeking to navigate the complexities of CoPS innovation, thus providing a strategic roadmap for collaboration and innovation management.},

abstract = {This paper presents a novel analytical framework to enhance the performance of reconfigurable intelligent surfaces (RIS)-integrated multiple-input-multiple-output (MIMO) free-space optical (FSO) communication systems. The study addresses critical challenges such as atmospheric turbulence, misalignment, and signal attenuation. It introduces a series-based approach to model the combined effects of Gamma-Gamma turbulence, generalized Rician pointing errors, and RIS size-related constraints. In contrast to previous studies, which often rely on oversimplified or idealized channel models, this framework provides closed-form expressions for the first time for the probability density function and cumulative distribution function of the end-to-end channel specifically designed for RIS-empowered (RIS-E) MIMO-FSO systems. These expressions capture the complex interactions between channel impairments and system parameters, enabling accurate performance evaluation in real-world deployments. The derived formulations provide key performance metrics, including outage probability, average bit error rate, ergodic capacity, data rate, and energy efficiency, for a variety of system configurations. Practical diversity combining techniques such as equal gain combining, maximal ratio combining, and selection combining are rigorously analyzed. In addition, asymptotic analyses at high signal-to-noise ratios offer simplified expressions that provide valuable insights into coding gain, diversity order, and system behavior under extreme conditions. A key contribution of this work is the investigation of the optimization of RIS placement, which improves signal alignment and reduces the outage probability, even under challenging atmospheric conditions. In addition, the study highlights the computational efficiency of the proposed framework through a detailed complexity analysis that confirms its feasibility for practical, large-scale applications. Monte Carlo simulations validate the theoretical findings, demonstrating strong agreement with the analytical results. These results confirm the transformative potential of RIS technology in mitigating turbulence-induced fading and misalignment. This research establishes RIS-E MIMO-FSO systems as a robust, energy-efficient solution for next-generation, high-bandwidth optical networks. Additionally, it provides practical deployment guidelines, ensuring the effective integration of RIS technology into real-world wireless communication infrastructures, thereby advancing the development of resilient and high-performance optical communication systems.},

abstract = {Bioactive glass (BG)/polylactic acid (PLA) nanocomposites have gained significant attention for bone repair applications due to their mechanical and biological properties. In this study, sol-gel-derived bioactive glass nanoparticles (nBG) with a mean diameter of 53.38?nm were surface-modified with (3-Aminopropyl) triethoxysilane (APTES) to ensure uniform dispersion within the PLA matrix. Composite materials containing 0, 2, 8, and 16?wt% of surface-modified bioactive glass nanoparticles (m-nBG) were synthesized using a solvent-evaporation method. The composites' mechanical properties (tensile and flexural), degradation rate, hydrophilicity, and cellular responses were evaluated. The addition of 2?wt% m-nBG significantly improved the mechanical performance, achieving a tensile strength of 37.14?MPa and a flexural strength of 72.2?MPa. However, increasing the filler content beyond this threshold resulted in agglomeration, leading to a reduction in mechanical strength, though the tensile modulus continued to rise with higher nanoparticle loading. Biodegradation tests showed that m-nBG fillers accelerated the degradation process, with higher filler concentrations further promoting matrix degradation and increasing water absorption. The 2?wt% m-nBG nanocomposite exhibited optimal cell viability, proliferation, and attachment, highlighting its potential for bone tissue engineering applications. These findings suggest that a balanced nanoparticle content enhances both mechanical integrity and biological activity in PLA-based composites.},

Instead of explicit and literal representations of loved ones, TeleAbsence describes poetic encounters with digital and physical traces left by the absence of others. TeleAbsence fosters illusory communications to conjure the feeling of being there with those no longer with us without using synthetic or generative representations and utterances. Our vision is deeply inspired by the Portuguese concept ?Saudade??the ?desire for the beloved thing, people, place, and moment, made painful by its absence.? We present our vision through five design principles: presence of absence, illusory communication, the materiality of memory, traces of reflection, and remote time, grounded in historical and cultural contexts. We present exploratory narratives to illustrate these principles and the concept of ambient co-presence using poetry, phone, piano, and pen as mediums. We discuss challenges and opportunities for future work, including representational strategies to depict lost loved ones, ethical issues, and the possible extension of TeleAbsence to historical public figures.},

Our work proposes an intuitive, user-friendly mobile-based framework named "SeeAround" that is capable of automatically providing real-time audio descriptions of the user's immediate visual surroundings. Our solution addresses this challenge by leveraging key point detection, image captioning, text-to-speech (TTS), optical character recognition (OCR), and translation algorithms to offer comprehensive support for visually impaired individuals. Our system architecture relies on convolutional neural networks (CNNs) such as Inception-V3, Inception-V4, and ResNet152-V2 to extract detailed features from images and employs a multi-gated recurrent unit (GRU) decoder to generate word-by-word natural language descriptions. Our framework was integrated into mobile applications and optimized with TensorFlow lite pre-trained models for easy integration on the Android platform.},

This study develops a new EEFDEA approach based on a proportional frontier-shifting strategy. Our approach applies an iterative procedure to find the equilibrium efficient frontier (EEF). Each iteration uses a proportional frontier-shifting model to improve an inefficient DMU to the efficient frontier by increasing its fixed-sum outputs. Meanwhile, the DMUs on the efficient frontier decrease fixed-sum outputs proportionally to ensure the total fixed-sum outputs are unchanged. Our theoretical developments show that the proportional frontier-shifting strategy is feasible and can finally obtain a unique EEF. The new approach allows DMUs to use their preferred input and output weights when determining the EEF. This generates an EEF that better aligns with real-world practices and avoids the need to construct it as a single hyperplane, as required by conventional EEFDEA methods. It also avoids unfair adjustments in fixed-sum outputs among the DMUs and eliminates the problem of peculiar efficiency evaluation results (i.e., some DMUs obtain extremely high, or infinity, efficiencies). Finally, we apply our approach to a case study of Chinese vehicle industry companies to demonstrate its usefulness and compare it with the previous representative approach.},

abstract = {Purpose



Despite the ongoing scholarly interest in greenwashing, it is not well known the impact of multiple institutional pressures on greenwashing in corporate social responsibility (CSR). Following the institutional logics perspective, this study investigates how three distinct logics - commercial, public, and social welfare - drive greenwashing and whether organizational capability for blending diverse CSR expectations reverses this link.

Design/methodology/approach



The current study conceptualized and tested an original model on how three institutional logics influence greenwashing in CSR, with the mediation effect of hybridization capability as a response to logic plurality. Partial least squares structural equation modeling was performed on a survey data, which was collected from 150 middle managers in Turkey.

Findings



The results show that while commercial logic has no direct or indirect impact on greenwashing, public and social welfare logics drive greenwashing in CSR. However, these effects are reversed when the CSR hybridization capability increases.

Practical implications



This study contributes to the understanding of what predicts CSR greenwashing by integrating a comprehensive theoretical framework involving multiple institutional logics, conflicting stakeholder demands, and organizational hybridity.

Originality/value



To the best of our knowledge, this is the first study that theoretically and empirically analyzed how the exposure of multiple external pressures affects the CSR greenwashing and how it can be reversed by CSR hybridization capability. This capability mitigates the threats and challenges of multiple logics and turns them into an opportunity to gain legitimacy in the eyes of stakeholders by preventing greenwashing.},

abstract = {Integrating data from multiple sources or views has become increasingly common in data analysis, particularly in fields

like healthcare, finance, and social sciences. However, clustering such multi-view data poses unique challenges due to the

heterogeneity and complexity of the data sources. Traditional clustering methods are often unable to effectively leverage the

information from different views, leading to suboptimal clustering results. To address this challenge, multi-view clustering

techniques have been developed, aiming to integrate information from multiple views to improve clustering performance.

These techniques typically involve learning a similarity matrix for each view and then combining these matrices to form

a consensus similarity matrix, which is subsequently used for clustering. However, existing approaches often suffer from

limitations such as the need for manual tuning of parameters and the inability to effectively capture the underlying structure

of the data. In this paper, we propose a novel approach for multi-view clustering that addresses these limitations by jointly

learning the consensus coefficient matrix and similarity graph. Unlike existing methods that follow a sequential approach

of first learning the coefficient matrix and then constructing the similarity graph, our approach simultaneously learns both

matrices, ensuring a more regularized consensus graph. Additionally, our method automatically adjusts the weight of each

view, eliminating the need for manual parameter tuning. Our approach involves several key steps. First, we formulate an

optimization problem that jointly optimizes the consensus coefficient matrix, unified spectral projection matrix, coefficient

matrix, and soft cluster assignment matrix. We then propose an efficient algorithm to solve this optimization problem, which

involves iteratively updating the matrices until convergence. To learn the consensus coefficient matrix and similarity graph, we

leverage techniques from matrix factorization and graph-based learning. Specifically, we use a self-representation technique

to learn the coefficient matrix (regularization graPh) and a graph regularization technique to learn the similarity graph. By

jointly optimizing these matrices, we ensure that the resulting consensus graph is more regularized and better captures the

underlying structure of the data. We evaluate our approach on several public image datasets, comparing it against state-of-the-

art multi-view clustering methods. Our experimental results demonstrate that our approach consistently outperforms existing

methods in terms of clustering accuracy and robustness. Additionally, we conduct sensitivity analysis to evaluate the impact

of different hyperparameters on the clustering performance. We present a novel approach for multi-view data clustering

that jointly learns the consensus coefficient matrix and similarity graph. By simultaneously optimizing these matrices, our

approach achieves better clustering performance compared to existing methods. Our results demonstrate the effectiveness and

robustness of our approach across different datasets, highlighting its potential for real-world applications in various domain.},

Although virtual reality (VR) has shown promise in addressing spatial comprehension challenges, questions remain regarding its effectiveness in supporting collaborative learning and sustained knowledge retention. This longitudinal study examined Collaborative Immersive Virtual Anatomy Laboratory (C-IVAL), an innovative VR platform designed to enhance traditional anatomy learning through integrated collaborative features, immersive technology, and serious game elements. We conducted an experimental study with 65 medical students to evaluate their knowledge acquisition and technology acceptance compared to its non-collaborative predecessor, the Immersive Virtual Anatomy Laboratory (IVAL). Our evaluation framework combined quantitative assessments (knowledge tests, comprising pre-test, immediate post-test, and delayed post-test) with Technology Acceptance Model (TAM) analysis. Knowledge assessment revealed significant cognitive improvements, with mean knowledge scores increasing from 2.48 to 3.94 in the immediate post-tests, while long-term retention of anatomy knowledge showed sustained engagement for over two months. Importantly, C-IVAL demonstrated significantly higher scores across all TAM dimensions than the non-collaborative IVAL system, particularly for perceived usefulness and intention to use. Post-session feedback analysis showed 73.8% positive responses, highlighting enhanced social presence, immersive engagement, and effective collaboration, with 26.2% of constructive feedback focusing on system refinement and feature enhancement.

the material blend exhibits sensitivity to both strain rate and temperature. As the

temperature rises, the yield strength and strain at failure decrease significantly;

while, the young's modulus only slightly decreases. Among several constitutive

models studied, including the G'sell and Jonas and Duan-Saigal-Greif-Zimmerman

behavior at elevated temperatures. To address this limitation, a new model named

Hentati-Mnif-Hfaiedh-Petit (HMHP) was developed by introducing a temperature

dependence into two key parameters of the ?Zhu et al.? model. This improvement

enabled the HMHP model to more accurately predict tensile behavior across a wide

temperature range. The results confirm that the new developed model, HMHP provides

a reliable prediction of tensile properties at different temperatures.},

As an immediate application of our new notion, we prove the security of the Naor-Yung paradigm in the quantum settings, with respect to a strong quantum IND-CCA security notion. This provides the quantum analogue of the classical dual key approach to prove the security of encryption schemes. Along the way, we introduce a new notion of quantum-query advantage functions, which may be used as a general framework to show classical/quantum separation for other cryptographic primitives, and it may be of independent interest.},

abstract = {Les sciences de gestion et du management sont largement reconnues pour la qualité de leurs formations et l'insertion professionnelle des très nombreux étudiants concernés, puisque près de 20% de l'ensemble des étudiants inscrits dans l'enseignement supérieur français suivent des formations dont la gestion constitue la discipline principale, une réalité encore trop souvent méconnue des responsables économiques et politiques. Peut-être plus méconnue encore est la recherche en sciences de gestion et du management. Et pourtant, au regard des nombres impressionnants d'étudiants formés et des nombreuses entreprises et organisations qui les accueillent chaque année aux termes de leur formation pour répondre aux besoins de l'économie et de la société française, il est paradoxal que les connaissances dispensées dans les différents champs disciplinaires des sciences de gestion et du management ne soient pas perçues comme les résultats de continuelles activités de Recherche & Développement.

La FNEGE a décidé en 2022 de lancer l'Observatoire de la recherche en sciences de gestion et du management avec le parrainage de la Conférence des Directeurs d'Ecoles Françaises de Management (CDEFM) et du réseau des Instituts d'Administration des Entreprises, IAE FRANCE.

Cet observatoire a pour objectif de dresser un panorama quantitatif et qualitatif de la recherche en sciences de gestion et du management dans les établissements d'enseignement supérieur français. Cela permet de mesurer l'ampleur de la production de connaissances de la communauté académique en sciences de gestion et du management, et de prendre conscience de ses impacts et contributions pour l'ensemble de ses parties prenantes, qu'ils s'agissent des chercheurs et enseignants-chercheurs, des étudiants et doctorants, des managers ?uvrant dans les organisations du tissu économique et social, ou de la société plus généralement.

A l'automne 2023, une enquête en ligne a été lancée avec le concours de Sphinx auprès des directions de 66 laboratoires français afin de collecter des données sur les effectifs leurs productions scientifiques, leurs impacts national et international sur la communauté académique, leurs contributions pour les étudiants et les doctorants, pour les praticiens, ainsi que pour leurs territoires et la société. A l'issue de cette enquête, Pascale BUENO MERINO, Directrice de la Recherche à l'EMLV Business School (De Vinci Higher Education), Professeur de Management stratégique, Habilitée à Diriger des Recherches, et Jean-Luc HERRMANN, Professeur Agrégé des Universités (Sciences de gestion et du management) à l'Université de Lorraine ont rédigé un rapport d'analyse des principaux enseignements de cet observatoire.

La première partie s'attache à apporter un éclairage sur l'impact académique de la recherche en sciences de gestion et du management en France. Plus spécifiquement, cette partie met en exergue tout d'abord les contributions des laboratoires français de gestion à la production de connaissances, puis le rôle des laboratoires français dans l'écosystème de la production de connaissances, et enfin l'impact de la recherche comme pilier de la formation académique en sciences de gestion et du management.

La seconde partie porte sur l'impact de la recherche française en sciences de gestion et du management sur les praticiens et la société. De façon plus précise, elle met tout d'abord en avant les efforts consacrés par les enseignants-chercheurs aux activités de dissémination scientifique et de recherche partenariale. Elle permet ensuite d'insister sur les liens étroits qu'entretiennent de nombreux laboratoires avec leur(s) territoire(s) d'implantation, avant de mettre en lumière l'engagement de plus en plus important des laboratoires dans la réalisation de travaux de recherche dédiés à la transition environnementale et sociétale.
