L’Axe de recherche « Nouveaux Matériaux, Systèmes Intelligents et Entreprises innovantes » organise ses travaux autour de quatre sous-axes de recherche majeurs :
La recherche de matériaux intelligents fonctionnels représente un défi majeur dans de nombreux domaines tels que l’automobile, l’aéronautique et la biomédecine. Dans ce contexte, nos chercheurs collaborent en mettant en commun leur expertise pour concevoir des métamatériaux bio-inspirés architecturés et des smart matériaux, depuis la phase de conception numérique jusqu’à l’optimisation des propriétés structurales et/ou fonctionnelles, en passant par la fabrication et la caractérisation expérimentale. Les technologies développées réunissent des compétences dans plusieurs domaines, notamment la modélisation et simulation numérique multi-échelles, la simulation par éléments finis, l’Intelligence Artificielle, l’impression additive, le smart manufacturing et les méthodes expérimentales.
Dans le cadre de la transformation numérique, la sécurité digitale joue un rôle primordial. Au sein de l’Axe ce thème englobe la cybersécurité, la sécurité des réseaux, la résilience et la cryptographie, revêtant une importance significative avec une visibilité à la fois nationale et internationale. Le deuxième thème porte sur les systèmes intelligents, qui sont des composantes essentielles de la transformation numérique. La recherche au sein de l’Axe dans ce domaine se concentre sur les interactions entre l’humain et la machine, que ce soit du point de vue visuel, audio et/ou tactile, ainsi que sur la robotique, les objets connectés, l’IoT, la réalité virtuelle, et la e-santé, en lien avec les récentes avancées de l’intelligence artificielle.
La manière d’organiser l’innovation et l’impact des innovations sur nos vies sociales, comportementales et organisationnelles revêtent une importance cruciale tant sur le plan théorique que pratique. Nos membres excellent à l’échelle internationale dans la compréhension et l’exploration du développement de nouveaux produits et processus, ainsi que dans d’autres domaines tels que la gestion des innovations technologiques, l’encouragement du talent, l’optimisation de la chaîne d’approvisionnement, la gestion avancée des entrepôts et des opérations, la promotion de marques, et l’impact qu’ils apportent aux individus, aux groupes et aux pays grâce à ces innovations. Nous avons également acquis une expertise dans le financement, le recrutement et le développement d’entreprises innovantes (entrepreneuriat et création de nouvelles entreprises).
Nous sommes très intéressés par la recherche de stratégies qui favorisent, promeuvent et gèrent les innovations dans ce monde numérisé et hyper-connecté.

abstract = {Consensus adjustment is crucial in group decision making (GDM), aiming to reduce discrepancies in decision makers' (DMs') judgments for final decision results. The consensus adjustments made by DMs are interactive rather than independent. However, few studies investigate the consensus adjustment problem from the perspective of interactions among DMs. This study first constructs a model to determine the total minimum consensus adjustment under the requirements of consensus threshold and individual-collective judgment bias. Then, a consensus adjustment approach based on cross-allocation scheme is proposed to address the inconsistency between individual and collective minimum adjustments, which concerns all DMs' individual favorable allocation results under the total minimum consensus adjustment. The cross-allocation scheme ensures unanimous support for the same allocation result among all rational DMs, thereby eliminating the discrepancies among them. Subsequently, the optimization model-based minimum consensus judgment penalty is formulated to handle the non-cooperative behaviors of DMs. Furthermore, we show how to determine the unique consensus adjustment result for the non-cooperative DMs using the cross-allocation scheme. Therefore, our study contributes by developing a new GDM method that conducts consensus adjustment allocation by considering interactions among DMs. Finally, a case study is employed to demonstrate the specific application of the new method and discuss its efficiency. Meanwhile, comparison analysis and simulation experiments are provided.},

abstract = {In recent years, significant development has been made in efficiency evaluation for Decision-Making Units (DMUs) with fixed-sum outputs. The Generalized Equilibrium Efficient Frontier Data Envelopment Analysis (GEEFDEA) approach introduced by Yang et al. (2015) is one of the most representative methods. In the GEEFDEA approach, all DMUs are adjusted to become efficient under the same set of weights, indicating that the Equilibrium Efficient Frontier (EEF) constructed consists of only one hyperplane. However, in practical scenarios under the Variable Return to Scale (VRS) assumption, the production frontier always consists of multiple hyperplanes, presenting a more complex shape. To fill this research gap, we propose an improved Equilibrium Efficient Frontier Data Envelopment Analysis approach. Our approach allows DMUs to have different weights for inputs, variable-sum outputs, and fixed-sum outputs, resulting in an EEF with multiple hyperplanes. It is noted that our new approach uses a non-linear model to obtain the EEF. We show that the model can be linearized in the case of a single fixed-sum output. In situations involving multiple fixed-sum outputs, we propose an algorithm based on the Expectation Maximization (EM) mechanism to solve the model to obtain an EEF. Finally, we illustrate the advantages of our new approach through a numerical example and a case study in the global motor vehicle industry.},

While Frakes and Wasserman (2020) conduct a thorough analysis of the markers and consequences of ??end-loading'', its use of an inadequate proxy for examination activity (i.e., Office action count dates) leads to incorrect conclusions about the examination process (i.e., widespread examiner procrastination)},

abstract = {The widespread integration of artificial intelligence (AI) technology in the realms of energy and the environment has emerged as a catalyst for transformative shifts toward low-carbon energy structures. However, existing literature and practical applications have yet to delve into the intricate ways in which intelligent technology influences energy structures. Consequently, this study addresses this gap by constructing a comprehensive theoretical model that encompasses robots and differentiated energy inputs. By drawing on the Chinese case, this research investigates the impact of AI on low-carbon energy structure transformation, both theoretically and empirically. The study's results reveal that AI technology significantly advances the cause of low-carbon energy transformation. Notably, this effect is manifested in the post-Industry 4.0 era and regions endowed with abundant renewable energy resources and strong governmental support for innovation. Rigorous robustness tests substantiate the existence of this relationship. Furthermore, adopting smart technology fosters energy structure transformation through industrial restructuring, and introduces the energy rebound effect, thereby partially offsetting its positive impact. Importantly, the study underscores that the efficacy of AI is further heightened when the influx of innovation factors surpasses a certain threshold. These findings furnish crucial evidence and policy insights for China and other developing nations, offering guidance on accelerating energy transitions and attaining carbon neutrality.},

abstract = {In this paper, we develop an innovative series representation for the sum of Rician non-zero boresight pointing error random variates based on the k - ? distribution, which is suitable for multiple-input multiple-output (MIMO) transmission for the first time. Then, using this new representation, we introduce a novel closed-form probability density function (PDF) approximation for the sum of Gamma-Gamma random variates with generalized pointing errors and atmospheric attenuation of MIMO free-space optical (FSO) communications. Statistical Kolmogorov-Smirnov tests confirm the accuracy of this approximation over a wide range of channel conditions. The significance of this approximation is emphasized by deriving closed-form expressions for the ergodic capacity, outage probability, and average bit error rate (BER) using Meijer's G-function. This paper provides a comprehensive analysis of the performance of MIMO FSO systems utilizing the equal gain combining (EGC) diversity technique under various conditions, such as different numbers of transmitter and receiver, turbulence intensities, the effects of non-zero boresight pointing errors, and path attenuation. The results show that using MIMO technology with more transmitters and receivers significantly improves the performance of FSO communication compared to other diversity techniques, including single input single output (SISO), and multiple input single output (MISO) systems. Detailed evaluations of the ergodic capacity, outage probability, and average BER performance at high signal-to-noise ratios provide additional insights. Monte-Carlo simulation results demonstrate the accuracy of the proposed approach.},

abstract = {Haptic exoskeleton gloves are a widespread solution for providing force-feedback in Virtual Reality (VR), especially for 3D object manipulations. However, they are still lacking an important feature regarding in-hand haptic sensations: the palmar contact.
In this paper, we present PalmEx, a novel approach which incorporates palmar force-feedback into exoskeleton gloves to improve the overall grasping sensations and manual haptic interactions in VR. PalmEx's concept is demonstrated through a self-contained hardware system augmenting a hand exoskeleton with an encountered palmar contact interface -- physically encountering the users' palm.
We build upon current taxonomies to elicit PalmEx's capabilities for both the exploration and manipulation of virtual objects.
We first conduct a technical evaluation optimising the delay between the virtual interactions and their physical counterparts.
We then empirically evaluate PalmEx's proposed design space in a user study (n=12) to assess the potential of a palmar contact for augmenting an exoskeleton. Results show that PalmEx offers the best rendering capabilities to perform believable grasps in VR.
PalmEx highlights the importance of the palmar stimulation, and provides a low-cost solution to augment existing high-end consumer hand exoskeletons.},

Given the prevalence of COVID-19 cases and the extensive volume of patient records lacking labels, this communication underscores our unique approach?conducting the first study on COVID-19 case diagnosis in an unsupervised manner. Our work operates under the assumption of prior knowledge regarding the number of classes, such as COVID-19, pneumonia, and normal, in a case study.
By adopting an unsupervised learning paradigm, we leverage the wealth of unlabeled data, reducing dependence on human experts for annotating numerous images. This paper introduces an enhanced version of a recent direct method where non-negative cluster indices and spectral embeddings are jointly estimated. Beyond the inherent advantages of this method, our proposed model introduces improvements through two additional types of constraints: (i) ensuring consistent smoothing of cluster labels across all views and (ii) imposing an orthogonality constraint on the matrix of cluster assignments. The efficacy of the proposed method is demonstrated using the public COVIDx dataset with three classes, showcasing promising results in categorizing radiographs. The proposed approach is tested on other public image datasets to assess its effectiveness.},

abstract = {Allocating carbon emissions abatement (CEA) is crucial for reducing carbon footprint of organizations (or decision-making units, DMUs) and mitigating global warming. However, discrepancies often arise among DMUs regarding CEA allocation. This study introduces a dynamic bargaining game approach to address the issue under the nonparametric production frontier analysis framework. Our approach employs an iterative process, allowing each DMU to propose its individual preferred CEA allocation proposal in each iteration. Subsequently, dynamic negotiations among the DMUs occur, leading to the eventual consensus on the CEA allocation result. Our theoretical analysis demonstrates that, at the end of the dynamic bargaining game, all DMUs will converge on the same CEA allocation result, termed as the consensus CEA allocation result. This agreement is reached despite each DMU customizing its individual CEA allocation proposal to suit its own interests. Moreover, we prove that this consensus CEA allocation result represents a Nash equilibrium solution, thereby ensuring its stability and acceptance among all DMUs. Finally, we provide a simple numerical example and a case study of CEA allocation across 27 European Union countries to illustrate the usefulness of our approach and compare it with prior CEA allocation approaches.},

Environmental knowledge management (EKM) has been studied mainly owing to the increasing awareness of environmental issues. Such issues have generated a warning in the tourism industry that has stimulated a new wave of research on EKM. EKM forges landscape characteristics and so destination image. In turn, EKM sounds affecting tourism destination which calls for destination personality which shows a research context less explored. From a knowledge management perspective, The present research aims to investigate on EKM to understand how it leverages tourists' and destination personality.
Design/methodology/approach
With the intent of exploring EKM, the research uses a quantitative analysis on a sample of 2,222 young Chinese tourists. In this context, EKM is linked with destination's personality and tourists' personalities, their satisfaction with the destination and their behavioral intentions.
Findings
By SPSS regression model, EKM and destination personality are positively linked. This positive relationship is also reflected on destination personality and destination satisfaction, behavioral intention.
Originality/value
The authors' original contribution to the knowledge management literature extends the new wave of research on EKM. The research also proves the need to make a close collaboration between tourists, the local community and marketers. Marketers need to pay more attention to what tourists want to do and see in the place visited. In a nutshell, there is the need of enforcing and promoting EKM.

abstract = {In recent years, remote work and communication via videoconferencing tools have become increasingly prevalent across various sectors, including education, where students and teachers use these platforms to attend virtual classes. Although videoconferencing offers advantages such as convenience and flexibility, it also has limitations. For instance, remote group work and practical activities may pose challenges, and students may experience decreased motivation to learn due to a lack of social interaction and support provided in traditional classrooms. To address these limitations, this study proposes ?V-Class,? an immersive multi-user virtual reality learning system that combines distance learning with traditional learning by immersing students in a virtual classroom and facilitating collaboration and hands-on activities. This study evaluates the effectiveness of our system ?V-Class? using both subjective and objective measurements to examine variables like presence, performance, collaboration, and engagement. It is compared to Zoom, a popular videoconferencing tool, with 50 participants. V-Class outperformed Zoom in all dimensions, indicating its potential as a superior solution for enhancing distance learning over videoconferencing tools.},

abstract = {Medical image segmentation often faces challenges related to overfitting, primarily due to the limited and complex training samples. This challenge often prompts the use of self-supervised learning and data augmentation. However, self-supervised learning requires well-defined hand-crafted tasks and multiple training stages. On the other hand, basic image augmentation techniques like cropping, rotation, and flipping, effective for natural scene images, have limited efficacy for medical images due to their isotropic nature.
While regional dropout regularization data augmentation methods have proven effective in image recognition tasks, their application in image segmentation is not as extensively studied. Additionally, existing augmentation methods often operate on square regions, leading to the loss of crucial contour information. This is particularly problematic for medical image segmentation tasks dealing with regions of interest characterized by intricate shapes. In this work, we introduce LCAMix, a novel data augmentation approach designed for medical image segmentation. LCAMix operates by blending two images and their segmentation masks based on their superpixels, incorporating a local-and-contour-aware strategy. The training process on augmented images adopts two auxiliary pretext tasks: firstly, classifying local superpixels in augmented images using an adaptive focal margin, leveraging segmentation ground truth masks as prior knowledge; secondly, reconstructing the two source images using mixed superpixels as mutual masks, emphasizing spatial sensitivity. Our method stands out as a simple, one-stage, model-agnostic, and plug-and-play data augmentation solution applicable to various segmentation tasks. Notably, it requires no external data or additional models. Extensive experiments validate its superior performance across diverse medical segmentation datasets and tasks.

journal = {Personnel Review},
abstract = {Purpose
This study investigates how compulsory citizenship behaviors (CCB) affect employees' energy and motivation to engage in other voluntary behaviors, such as service-oriented citizenship behavior and creativity. Specifically, we explore how employees' perceptions of job overload mediate this relationship, based on their generational differences.
Design/methodology/approach
This study employed a time-lagged survey design to collect data from 265 frontline employees and their supervisors in Pakistani-based organizations. The data was collected in three rounds, with a three-week gap between each round.
Findings
The findings suggest that role overload, resulting from compulsory citizenship pressure, undermines millennial employees' service-oriented organizational citizenship behavior (OCB) and creativity. However, these negative effects are less salient among non-millennials.
Practical implications
The findings of this study provide valuable insights for managers, emphasizing the importance of exercising caution when imposing excessive citizenship pressures on employees against their will. In addition, organizations and human resource (HR) managers should consider devising policies for formal recognition of voluntary behaviors that contribute to organizational effectiveness.
Originality/value
This study contributes to existing CCB research by unraveling the previously unexplored mediating role of role overload and the contingency role of generational difference in explaining how and when coerced citizenship demands hinder employees' propensity to engage in service-oriented OCB and creativity.},

abstract = {Piezoelectric bimorph cantilevered beams are frequently employed in energy harvesting applications. The use of macro-fiber composites, which combine piezoelectric fibers with rectangular cross-sections and interdigitated electrodes, has significantly enhanced their performance by enabling operation in the 33-mode of piezoelectricity, thereby increasing conversion efficiency. In this paper, the Timoshenko beam theory is applied to overcome the limitations of the Euler-Bernoulli theory in modeling transverse vibrations of harvesters with low slenderness ratios (length to thickness ratios). The mixture rule formulation is applied to determine the equivalent properties of the macro-fiber composite (MFC) structure. The electromechanical properties of a representative volume element (RVE) bounded by two successive interdigitated electrodes are coupled to the overall electro-elastic dynamic model of the structure using the Timoshenko theory. Frequency response functions for the power and tip vibration displacement of the MFC bimorph beam are determined from the model. Experimental data from the literature are used to validate the improved results predicted by the model developed in this paper. A comparative analysis between the electromechanical responses predicted using a model based on Timoshenko and a model based on Euler-Bernoulli theory is conducted showing agreement, for harvesters with large slenderness ratios and discrepancies of up to 30 % for low slenderness ratios. It has also been shown that the model based on Euler-Bernoulli theory overestimates both the mechanical and the electrical responses for low slenderness ratios as the shear and rotary inertia effects are not negligible in this case.},

Importantly to our work, it has been recently shown that public-key encryption (PKE) from one-way functions (OWF) is possible if we consider quantum public keys. Notice that we do not expect classical PKE from OWF given the impossibility results of Impagliazzo and Rudich (STOC'89).
However, the distribution of quantum public keys is a challenging task. Therefore, the main question that motivates our work is if quantum PKE from OWF is possible if we have classical public keys. Such protocols are impossible if ciphertexts are also classical, given the impossibility result of Austrin et al.(CRYPTO'22) of quantum enhanced key-agreement (KA) with classical communication.
In this paper, we focus on black-box separation for PKE with classical public key and quantum ciphertext from OWF under the polynomial compatibility conjecture, first introduced in Austrin et al.. More precisely, we show the separation when the decryption algorithm of the PKE does not query the OWF. We prove our result by extending the techniques of Austrin et al. and we show an attack for KA in an extended classical communication model where the last message in the protocol can be a quantum state.},

However, traditional sensor-based motion capture systems are limited by their high cost and the need for multiple cameras and physical markers. To address these limitations, cloud-based HPE tools, such as DeepMotion and MOTiON by RADiCAL, have been developed. This study presents the first scientific evaluation of MOTiON by RADiCAL, a cloud-based 3D HPE tool based on deep learning and cloud computing. The evaluation was conducted using the CMU dataset, which was filtered and cleaned for this purpose. The results were compared to the ground truth using two metrics, the Mean per Joint Error (MPJPE) and the Percentage of Correct Keypoints (PCK). The results showed an accuracy of 98 mm MPJPE and 96% PCK for most scenarios and genders. This study suggests that cloud-based HPE tools such as MOTiON by RADiCAL can be a suitable alternative to traditional sensorbased motion capture systems for simple scenarios with slow movements and little occlusion.},

This paper conceptually aims to discuss the dual role of knowledge management (KM) and technological innovation, which brings about innovations, although it can be limited by psychological and emotional ownership.
Design/methodology/approach
This study examines the real impact of the paper on KM and technological innovation in family small to medium enterprises (FSMEs). This is a unique context affected by psychological and emotional ownership. However, COVID-19 has forced FSMEs to consider new strategies and practices to preserve their competitive advantage.
Findings
In this scenario, knowledge exchange, knowledge absorption and technology adoption appear relevant to the innovation process. This study offers a framework for how the duality of KM and technological innovation affects innovation.
Originality/value
Although extant research has explored technological innovation outcomes, a literature review reveals that accumulated studies on the drivers of technological innovation and KM in the context of FSMEs require further inquiry. Family members' emotional ownership may foster KM because identification with organizational goals enhances individuals' willingness to access and share information and stimulates new products and technological development.},

empirically tested the relationships among four factors: attitude toward buying wine
based on SM recommendations, perceived risks, intention to buy wine on SM, and
consumer intention to become an SM wine cooperator. Findings indicate that the
intention to be an SM wine cooperator is positively correlated with attitude toward
buying wine based on SM recommendations and the intention to purchase wine on

Immersive virtual reality (IVR) and serious games (SGs) provide innovative and immersive learning experiences that enhance students' understanding and retention of anatomical concepts and improve the effectiveness of anatomy education. This work aims to develop and evaluate the effectiveness of IVAL,11Immersive Virtual Anatomy Laboratory. an Immersive Virtual Anatomy Laboratory, for immersive and engaging learning experiences. A study involving dozens of University students assessed the efficacy of this innovative tool, resulting in high levels of satisfaction, success, and learning outcomes. IVAL was found to be an effective tool in promoting learning and retention of anatomical concepts, with participants highly rating the tool regarding engagement and learning enhancement. This study demonstrates that immersion in a 3D representation of the skeletal system through VR is essential for a deep knowledge of anatomical learning.

solely of humans, or of technology, but instead arises from an emergent interaction between
the two. This, emergent, account of agency deepens our understanding of unfolding IS practice,
but its largely cognitive orientation remains naïve towards affectively-sensed motivations that
also form part of this interaction. By implication, a sociomaterial perspective lacking an affective
dimension offers an incomplete conceptualisation of information systems. In response, an
affectively-informed negative ontology encourages IS researchers to extend their focus beyond the
visible, to encompass how actors' receptiveness towards material objects (discourses, technologies)
is shaped by deep, affectively-derived motivations of which they are not focally aware, but
which nonetheless acquire agency in contributing to a sociomaterial outcome. A central argument,
and illustrative empirical vignette, illustrate how the concepts of sociomateriality, affect,
and negative ontology combine to offer researchers an enhanced understanding of relational
agency. A discussion follows, exploring some initial ontological, epistemological and methodological
implications of an affectively-informed negative ontology for IS research.},

abstract = {The present research addresses the gap in studies on B2B marketing comparing a diverse set of socio-economic factors (ROA and Tobin' s Q) and its effects on people, planet, and profit. Studies in the past have shown that firms haven't been able to gain a long-term competitive advantage by using environmental strategies. Hence, the research analyses how 371 B2B firms from developed and emerging European countries achieve competitive advantage through green marketing strategies. Additionally, those firms are also assessed in reference to their level of engagement with environmental, social, and governance strategies. Our findings highlight that the more the engagement in green marketing by B2B firms, the greater the green competitive advantage that B2B firms in developed European markets can achieve. Hence, the study explores the relationship of B2B marketing, environmental sustainability, and corporate profitability, providing insights into how European firms can balance their financial objectives with their social and environmental responsibilities. The originality of the research stressed the need to pursue social and environmental goals and to preserve the future of people, planet, and profit through green marketing strategies. Investing in future business models and green competitive advantage is especially important for B2B European emerging firms' markets.},

abstract = {Drones are increasingly used for last-mile delivery due to their speed and cost-effectiveness. This study focuses on a novel locker-drone delivery system, where trucks transport parcels from the warehouse to lockers, and drones complete the final delivery. This system is ideal for community and intra-facility logistics. The research optimises the network design by determining the location of lockers, the number of drones at each locker, and the assignment of demands to lockers, minimising operating costs. Both single-parcel and multi-parcel capacity drones are examined. We build an optimisation model for each system, considering drone service capacity as a critical constraint. We design an algorithm combining average sample approximation and a genetic algorithm to address demand uncertainty. The algorithm's efficiency is validated through comparative analysis with Gurobi. Numerical experiments, using real and generated data, optimise the network design. Results show that the multi-capacity drone system requires fewer lockers and drones than the single-capacity system. Although the single-capacity system yields lower drone delivery costs, it incurs higher truck delivery costs. Additionally, a comprehensive cost analysis compares the cost-efficiency of the locker-drone system with a conventional drone delivery system, revealing the cost-saving advantage of the locker-drone system.},

According to the experimental results, the RD values were found in good agreement with the workability of the investigated mixtures. Moreover, the RD values were well correlated with the coupled effect of the relative solid packing fraction of coarse aggregate (?/?max) and viscoplastic properties of the investigated CVC mixtures. Furthermore, a strong correlation was established between the rheological properties of the lubrication layer, RD values, and the ?/?max of coarse aggregate.},

abstract = {This study investigates why and when employees' observations of supervisors' ostracism of coworkers elicit their own feelings of guilt. In this connection, observers' silence might function as a mediator, and leader-member exchange quality could moderate the process. The tests of these predictions rely on two studies, undertaken in Pakistan: a temporally separated field study using three-wave data (N = 219) and a scenario-based experiment (N = 118). The combined results indicate that employees feel guilty for remaining silent when they witness supervisor ostracism of other colleagues. The positive relationship between such observations of supervisor ostracism and silence behavior is more pronounced among employees who enjoy high-quality relationships with their supervisor. In addition to establishing key theoretical insights, this article alerts organizations to a critical mechanism (silence to avoid upsetting supervisors) by which employees' observations of how supervisors ostracize others can escalate into their own sense of guilt.},

abstract = {CAD/CAM technologies have driven substantial progress in dentistry, replacing traditional plaster by a digital chain mainly using STL files. The first step in this chain is the digitization made by IOS, which allows a transition from the real world to a digital model.
Initially, the STL files issued of the IOS's intended as a support to design the prostheses. They also have proven valuable for comparing geometric and dimensional differences between two files, aiming determining the quality of IOS's or/and also between different dental protocols.
Following a bibliographic study of the scientific literature, two main methods of comparing by superimposing STL files emerge: 1) the use of a best-fit algorithm and 2) adding physical geometric elements (landmarks), such as spheres, cylinders and cones, on the dentition to be scanned.
On one hand, best fit algorithm relies on the scanned surface range. When applied to full-arch models with additional surfaces like part of palate, gum, it results in a loss of precision. Also, it is necessary to take into account the biases of the variability of the scanned surfaces, the complexity of the geometry, and its sensitivity to digitization errors. However, it's a simple and readily applicable method. For instance, it enables to create colored maps illustrating differences between the files, determine minimum and maximum recorded values, and compute the standard deviation.
On the other hand, using geometric landmarks allows us to measure deviations, linear distances, spatial distortion and cross distances, between particular points of the landmarks (centers of spheres, head of cones, cylinders axis). Finally, overall or local trueness computation is possible. This method ranging from measuring arch opening to torsion allows great precision and repeatability, but is very difficult to implement in vivo.
My research works focuses on introducing an effective protocol solution. This involves proposing a hybrid post-processing method to integrate virtual reference geometries directly onto scans. Ultimately, this method aims to achieve the same results as landmark-based approaches, either without explicit landmarks or through a combination of localized best fit and geometric landmarks.},

abstract = {Objective: This study aims to assess the accuracy of dental arch models printed with different vat photopolymerization technologies SLA (stereolithography), DLP (digital light processing) and LCD (liquid crystal display) while considering different resin types and layer thicknesses.
Materials and methods: Based on a STL file of a dental arch, 80 models were printed flat on the build plate using the specific resins from a SLA printer (Draft V2 (DR) and Grey V4 (GR) resin on Form 3+ Auto, Formlabs), a DLP printer (printed with different resin (Die and model 2 (DM) on Pro95S, SprintRay), a LCD printer (Aqua-Gray (AG) on Sonic Mini 8Ks, Phrozen) and according to the different layer thicknesses recommended by the manufacturer for each resin. The production time (printing and post-processing) of 10 models printed with the same resin and layer thickness was recorded. The STL files of the printed models were obtained after scanning with the highest precision program of a desktop scanner. A same mesh processing of the 80 STL files and the initial STL file was performed for better comparison. Accuracy was assessed as the area of valid distance between the STL of a printed model and the initial STL file following a best fit comparison with a 3D analysis software (Zeiss Inspect).
Results: The production time was the fastest with the DLP printers. Only the resin DR200 (Draft V2 resin printed with a layer thickness of 200?m) had an equivalent production time as DM100 (Die and model resin printed with a layer thickness of 100?m). Accuracy amongst the different printed models for a specific resin and a given thickness layer significantly increases according to the following sequence: AG50 < DM50 < DM170 < DM100 = DR100 = DR200 = GR100 < GR50.
Conclusion: A SLA printer has the best accuracy over the DLP and LCD. It's possible that hardware of the vat photopolymerization technologies may explain the differences in accuracy.
Clinical relevance: Within a dental laboratory seeking to optimise both accuracy and efficiency, mass printing of models with a layer thickness of 200?m on an automated SLA printer can be recommended.},

Stl files obtained with IOS are the first step for the digital manufacture of dental prostheses. Their quality, characterized with precision and accuracy are the key terms to guarantee efficiency in patient care. However, several parameters influence them, such as the environment (temperature, brightness, etc.), the practitioner (level of expertise, fatigue, handling the scanner, etc.), the patient (tongue, head, saliva, complex shapes, etc.) and the scanner (speed, rate, resolution, starting point, trajectory, tip, etc.).
In the medical sector, the use of robotics is getting more common to improve precision in surgery for example. In this project, a cobot i.e. a collaborative robot (UR5e from HMI-MBS), combined with the Care Stream CS3800 IOS, one of the most interesting scanners on the market are used to ensure repeatability of the experiments and to quantify the impact of the environmental factors. Then results are compared in a same protocol with files obtained manually by a practionner.
In the study, we assume that we are working on the restoration of a molar for an adult with standard dentition using a sphere (canonical form) whose material and diameter are similar in size to an adult molar. Given the complex shapes of the tooth and multiple parameters involved, initial assumptions are made. Indeed, we assume we are working in a dentist's surgery environment and using only the wireless side with its standard tip for the scanner.},

Natarajan and Zhang (FOCS 2023) then showed that the quantum bound is preserved for the specific case of the CHSH game. Extending the proof techniques of Natarajan and Zhang, we show that the compilation procedure of Kalai et al. preserves the quantum bound for two classes of games: XOR games and d-outcome CHSH games. We also establish that, for any pair of qubit measurements, there exists an XOR game such that its optimal winning probability serves as a self-test for that particular pair of measurements.},

While conventional molded or extruded polymer materials are well known and characterized via standardized procedures, this is not the case for 3D printed polymers. More precisely, it is of prime importance to better understand the influence of the 3D photopolymerization process and resin chemistry on the final mechanical properties of the object [4]. In our work, we formulated in-house acrylate resins with controlled resin chemistry. The resin physico-chemical properties and their printability were fully characterized. In particular, we investigated the influence of the nature of the acrylate monomer on the resin properties. Besides, after successful printing, the resin mechanical properties were investigated via Dynamic Mechanical Analysis (DMA) in flexion to determine the elastic modulus of the final materials. The results were compared to a molded analog acrylic polymethyl methacrylate (PMMA) and to commercial resins. We observed that by tuning the resin formulation and optimizing the printing process, it is possible to achieve PMMA-like stiffnesses with 3D printed pure acrylate resins. A statistical analysis was also performed, revealing a greater dispersion of the results in terms of reproducibility for 3D printed materials (both commercial and formulated resins) with respect to that in molded PMMA. However, our homemade resins have a lower dispersion than commercial resins, which underlines the importance of controlling both resin chemistry and printing parameters.},

abstract = {3D printing, also known as additive manufacturing, has emerged as a versatile and multidisciplinary field with widespread implications. It intersects with various domains including engineering, medicine, art, and materials science. This technology's ability to convert digital designs into physical objects layer by layer has revolutionized industries such as aerospace, automotive, and consumer goods by facilitating rapid prototyping and customization. Moreover, this technology has spurred advances in materials science through precise material manipulation, leading to innovative materials with enhanced properties. Challenges such as material limitations, process refinement, and legal concerns persist, but 3D printing's interdisciplinary nature continues to drive transformative advancements across various sectors. Therefore, multiphysics optimization plays a pivotal role in advancing the realm of 3D printing by addressing the intricate balance between conflicting design objectives. In this innovative manufacturing process, where material properties, structural integrity, print speed, and cost-effectiveness often collide, multiphysics optimization emerges as a critical tool. It allows designers and engineers to systematically explore a vast design space, enabling the identification of optimal solutions that consider not only a singular objective but also a spectrum of interrelated goals. By optimizing factors such as layer thickness, infill density, and printing speed, practitioners can achieve outcomes that strike harmonious equilibrium between strength, quality, and efficiency. Ultimately, the integration of multiphysics optimization into 3D printing catalyzes the creation of functional and intricately designed objects, revolutionizing industries ranging from aerospace to healthcare and redefining the boundaries of additive manufacturing possibilities.},

abstract = {Rheological evaluation has emerged as a critical facet in 3D printing, playing a pivotal role in enhancing the precision, efficiency, and quality of the additive manufacturing process. As 3D printing continues to expand across various industries, the study of how materials flow and deform has gained prominence for its capacity to influence material behavior during deposition, layer bonding, and solidification. Rheological evaluation contributes to the optimization of the 3D printing process itself. By studying how materials respond to temperature changes, shear forces, and extrusion rates, engineers can fine-tune printer settings to achieve optimal results. Such insights enable adjustments to printing speed, temperature profiles, and nozzle size, ultimately influencing material flow, layer adhesion, and overall structural integrity. Rheological evaluation stands as an indispensable tool in the optimization of 3D printing processes. Its impact spans material selection, formulation, process refinement, and quality control, all of which contribute to the creation of high-quality, precisely fabricated 3D-printed objects. As additive manufacturing continues to evolve, rheological insights will undoubtedly remain instrumental in pushing the boundaries of design, functionality, and performance in 3D printing across diverse industries.},

abstract = {We explore the impact of architectural disorder on the linear elastic behavior of lattice materials through 2D beam network numerical simulations. Different initially periodic geometries are first selected as representative of mechanically isotropic or anisotropic structures and low, intermediate, and large connectivity. The introduction of disorder induces spatial fluctuations in the local elasticity tensor at the local scale. Through proper coarse-graining, a well-defined continuum-level scale elasticity tensor is revealed. Increased disorder contributes to rendering initially anisotropic materials more isotropic. The impact of disorder on material stiffness depends on lattice connectivity: disorder softens lattices with high connectivity and stiffens those with low connectivity, while maintaining the linear scaling of elastic modulus with density for high connectivity and cubic scaling for low connectivity. Disorder introduced in lattices with intermediate fixed connectivity exhibits both scaling: linear scaling at low density and cubic scaling at high density, with the crossover density increasing with disorder. Contrary to traditional formulations, this study demonstrates that connectivity is not the sole parameter governing elastic modulus scaling. It opens a promising route to explore novel mechanical properties in lattice materials by introducing disorder into the architectures.},

While the theremin is typically invoked in HCI to emphasize the importance of the tactile modality, we interrogate how I, the player, attained musical proficiency without touch. Through a thematic analysis of 235 journal entries, our study distills my strategies for navigating the instrument as well as my personal transformations along the way. We discover that without touch, accurate and musical playing on the theremin relies on continuous auditory feedback, proprioception, and imaginative processes. We discuss challenges and opportunities for embodied and tangible interaction in light of these findings.},

La fréquence fondamentale et la durée de quatre phrases déclaratives, quatre questions polaires, quatre énoncés exprimant l'incrédulité (1 à 4 syllabes) de deux apprenantes ukrainiennes débutantes en français ont été comparées avant et après quatre entraînements hebdomadaires. Les apprenantes devaient écouter un enregistrement de référence, puis visualiser le modèle sur la tablette, tracer l'intonation manuellement, écouter le résultat synthétisé, et tracer et écouter leur tracé sans guide. Elles produisaient initialement des phrases déclaratives avec une intonation ascendante, et ont différencié les déclarations et les questions polaires après l'entraînement. L'expression de l'incrédulité s'est améliorée pour l'une. L'autre a montré quelques difficultés à maîtriser cette technologie. Cette première étude de cas utilisant la synthèse vocale contrôlée gestuellement est une approche prometteuse permettant plus de pratique de l'intonation en classe.},

abstract = {The increasing global warming and soaring fossil fuel prices have made energy generation minimization a crucial objective. As a result, the relevance of smart grids has significantly grown, especially in the context of regulating energy demand based on available resources. This necessitates the implementation of Demand Side Management (DSM) tools for effective regulation. While various models and architectures have been developed for smart grids, the utilization of holonic architectures remains limited in existing literature. In this paper, we propose a holonic architecture specifically tailored for smart grids, which proves to be highly advantageous. Holonic architectures are particularly valuable in smart grids as they enable seamless operation among different actors, even during technical challenges. Our proposed model consists of interconnected agents forming holons, with five agents working in tandem to ensure flexibility across multiple aspects. We have tested this model in three different scenarios. The first scenario represents a healthy grid. The second scenario simulates a grid with production mismanagement. Lastly, the third one simulates a grid experiencing a region-specific blackout. Results show how the grid distributes the available energy depending on the available production, storage (if any) and the assurance of the distribution across the various requesting holons.},

abstract = {This study introduces a groundbreaking structure for semi-supervised learning based on graphs. Our technique provides an all-encompassing strategy that simultaneously tackles the challenges of label prediction and linear transformation. Specifically, the linear transformation we advocate is designed to forge a distinguishing subspace, thereby significantly compressing the data's dimensionality.In advancing semi-supervised learning techniques, our framework particularly focuses on effectively utilizing the intrinsic data configuration and the provisional labels related to the unlabeled examples in our possession. This distinctive methodology leads to a more sophisticated and discriminative form of linear transformation. Tests carried out on authentic image datasets clearly validate the efficiency of the method we advocate. These tests repeatedly show enhanced performance in contrast to semi-supervised strategies that address the fusion of data and label deduction in isolation.},

According to the literature on female entrepreneurship, women entrepreneurs are faced with specific challenges that influence their entrepreneurial intention such as a lack of self-confidence, caused by gender stereotypes, and conflict between family life and entrepreneurial career. More precisely, our research aims to determine how psychological entrepreneurial support is implemented in the incubation process to overcome these specific challenges, and the mechanisms for strengthening female entrepreneurial intention analyzed at both intrapersonal and interpersonal levels. We discuss the implications of our findings on related research into business incubators and the design of mentoring programs adapted to the needs of women entrepreneurs.},

We argue that IB scholars can go beyond existing approaches to explain how firms act when facing sanctions. Moreover, we suggest that studies of firms facing sanctions help to reassess some of the assumptions underlying the prevailing theoretical explanations.
We contribute with systematic view on strategy options that international and domestic firms may implement when faced with sanctions.},

The results show that trust-building can effectively make more revenue for the system of the online recycling platform with enhanced demand if the cost of the trust-building construction is relatively low. The revenue-sharing contract is more profitable than the cost-sharing contract but fails to achieve optimization in the integrated setting. We find a new decision support tool for optimal strategies under different decision-making models.},
