L’entrée des pratiques anticoncurrentielles sur le marché émergent des services de Mobile Money
Authors: Onchi Ngongang Vanelle Dimitri
Published: February 2022

Par ses spécificités, la monnaie mobile est en passe de permettre une forte inclusion financière dans les pays faiblement bancarisés ou longtemps laissés à la marge des services financiers. Un marché de services s’est construit tout autour et, désormais, les banques, les microfinances sont en concurrence avec les Opérateurs de Télécommunication Mobile (OTM), détenteurs de l’Unstructured Supplementary Service Data (USSD) nécessaire non seulement à la réalisation des opérations financières de monnaie mobile, mais également à la liaison avec des clients potentiels. Ce rôle relativement récent des OTM peut susciter des préoccupations concurrentielles, notamment lorsqu’un OTM, en position dominante sur le marché des télécommunications, est également présent ou est un acteur actif sur le marché des services de monnaie mobile. La tentation est en effet grande qu’il utilise sa position dominante pour évincer tout concurrent sur le marché aval des services de Mobile Money. Cette étude prospective se propose d’attirer l’attention des autorités de concurrence sur le sujet, et de suggérer, sur la base des outils du droit de la concurrence, des pistes susceptibles de neutraliser ces préoccupations concurrentielles avant toute constitution d’oligopole.
Les contrats d’ istisna’a dans le financement bancaire islamique
Authors: Al Shattnawi Sinan
Published: February 2022

Les banques islamiques n’étaient pas autorisées à financer les projets de développement des gouvernements par le biais de formules de financement qui contredisent les lois de ces gouvernements. Considérées comme des sujets interdits, ces formules offraient des avantages considérés comme illégaux parce qu’interdits par la loi islamique. Il n’est notamment pas acceptable que lesdites banques financent des projets à caractère privé par des prêts avec intérêt ( riba ), qui sont illégaux. Le contrat d’ istisna’a apparaît alors comme la formule adéquate d’un point de vue religieux et économique pour financer divers projets gouvernementaux. Il peut être défini comme un contrat par lequel le client, en tant qu’« acquéreur final » ou « maître d’ouvrage », cherche à acquérir un bien nécessitant un processus de fabrication. La banque, en tant que « vendeur » ou « maître d’œuvre », s’engage à acheter les matières premières et à livrer le bien à fabriquer selon une description prédéfinie des caractéristiques du produit, à un prix fixé et payable selon les modalités convenues au contrat.
Les premiers pas de la justice pénale négociée en France et au Royaume-Uni
Authors: Eeckhoudt Marjorie
Published: February 2022

Présents au Royaume-Uni depuis 2014 et en France depuis 2016, les outils de la justice pénale « négociée » ont permis de conclure 26 accords à ce jour : 14 Conventions judiciaires d’intérêt public du côté français, 12 Deferred Prosecution Agreements du côté britannique. Progressivement, un cadre s’est dessiné permettant de comprendre, à la lecture des accords et des décisions de justice qui les accompagnent, quelles sont les conditions requises et les conséquences encourues. Si l’efficacité des dispositifs est largement saluée, certaines incertitudes demeurent de part et d’autre de la Manche. Incitées à coopérer largement pour éviter un procès long et coûteux, les entreprises n’ont pas de garantie que l’accord sera conclu ni qu’elles échapperont aux sanctions extraterritoriales. Non seulement les entreprises s’exposent à des conséquences financières lourdes, mais les personnes physiques sont également susceptibles d’être poursuivies, c’est pourquoi une réflexion s’impose afin d’assurer une plus grande sécurité juridique et préserver l’intérêt de la justice.
Le blocage de « Parler », le droit antitrust et le libre marché des idées
Authors: Nielson Nathalie
Published: February 2022

À la suite de la suppression du réseau social « Parler » du Play Store de l’App Store ainsi que du Cloud AWS en début d’année 2021 pour manque de modération des contenus violents, une plainte a été portée contre Amazon pour violation de la Section 1 du Sherman Act (lutte contre les ententes). L’auteur de la plainte alléguait une entente de l’hébergeur Cloud avec Twitter. Mais cette plainte fut in fine retirée, le réseau ne parvenant pas à démontrer suffisamment la réunion des conditions constitutives de l’entente. Toutefois, le déroulement de cette courte affaire antitrust ne manque pas d’interpeller sur le rôle croissant des géants du numérique dans le contrôle et la circulation des informations et sur la place du droit de la concurrence dans le libre marché des idées.
Pour une éthique élargie des médias : l’hypothèse de la sincérité
Authors: Chambat-Houillon Marie-France
Published: February 2022

En étudiant un exemple d’utilisation d’images de fiction dans un journal télévisé bolivien pour témoigner d’un accident d’avion en 2009, la contribution entend montrer comment la sincérité constitue un enjeu éthique fondamental pour les médias parce qu’elle engage leur responsabilité énonciative. Les conditions de leur croyance reposent sur la convocation d’un crédit de sincérité à l’initiative des publics. Dès lors, en tant que responsabilité communicationnelle partagée, la sincérité contribue à abonder une éthique des médias plus large que le simple respect du cadre déontologique régulant l’exercice des professionnels des médias.
Défaire le freak show . Adam Pearson et l’éthique de la représentation du handicap à la télévision
Authors: Assaf Marie , Ségard Arthur
Published: February 2022

Dans un documentaire diffusé sur la BBC3 en 2016, le présentateur britannique Adam Pearson traverse les États-Unis pour aller à la rencontre de « freaks », c’est-à-dire de personnes handicapées qui gagnent leur vie en spectacularisant leur handicap. Pearson, lui-même handicapé et militant pour les droits de cette population, se montre d’abord réticent quant à ce type de spectacle, considéré comme dégradant dans le paradigme actuel de représentation des personnes handicapées à la télévision (notamment symbolisé par le Téléthon). Ce voyage s’assimile pour lui à une enquête existentielle, qui lui permet de remettre en cause son propre rapport à son corps et à son identité, en se confrontant aux différents modèles éthiques proposés par les personnes qu’il rencontre. Plutôt que d’imposer une morale transcendante, compassionnelle, qui représente les personnes handicapées comme des « victimes », et qui peut avoir une dimension rassurante pour les spectateurs valides, Pearson présente une série de « face-à-face » intersubjectifs, imprévisibles, parfois inconfortables, qui dessinent une nouvelle éthique de la représentation du handicap.
Confessions télévisées au Vietnam : la télévision est-elle un tribunal ?
Authors: Nguyen-Pochan Thi Thanh Phuong
Published: February 2022

En 2020, l’ONG Safeguard Defenders a rendu public son rapport sur les confessions télévisées au Vietnam dans lequel elle questionne la responsabilité des médias impliqués dans cette « violation des droits de l’homme ». Cette pratique rend particulièrement saillante la question de l’éthique journalistique dans la mesure où les journalistes ont directement participé à la production et la diffusion de ces confessions forcées et de leurs images. Notre étude examine l’éthique journalistique au croisement avec l’éthique du voir à partir des trois instances de l’image selon la distinction de Roland Barthes (1980) : l’ operator , le spectator et le spectrum . Nous appliquons la méthode sémio-pragmatique afin d’analyser les trois retransmissions télévisées des confessions forcées : celle des dissidents politiques (en 2009), celle d’un ancien cadre du Parti communiste vietnamien (en 2017) et celle des paysans du village de Ðồng Tâm (en 2020).
Le projet de service express métropolitain bordelais confronté aux nouveaux choix de la Métropole
Authors: Broucaret Christian
Published: February 2022

Le projet de service express métropolitain bordelais se caractérise par un degré de maturation peut-être plus élevé que celui de la plupart des autres SEM recensés notamment par SNCF Réseau. Il a été initié dès 2015, et les premières actions de densification de l’offre qui y sont liées sont déjà en vigueur. On notera également que ce projet a fait jusqu’à récemment l’objet d’un large consensus en associant la Métropole et la Région Nouvelle Aquitaine, et qu’il comporte un volet routier avec une ligne de cars à haut niveau de service vers le secteur de l’Entre-deux-Mers non desservi par le rail.
Willingness to Participate in Clinical Research Among Individuals With Cognitive Impairment
Authors: Li Mengchi , Kim Hyejin , Sereika Susan M. , Nissley Trevor J. , Lingler Jennifer H.
Published: February 2022

This secondary analysis examined (1) factors associated with willingness to participate in clinical research for cognitive health among individuals with cognitive impairment and their care partners, and (2) concordance regarding such willingness between individuals with cognitive impairment and their care partners (dyads). Neuropsychological factors and willingness to participate in clinical research were collected using self-reported questionnaires. Participants' sociodemographic and clinical information was extracted from the University of Pittsburgh Alzheimer's Disease Research Center record. Binary logistic regression and Cohen's kappa coefficient analyses were performed. Greater trust in medical researchers (
p
= 0.031, B = 0.127) and more severe cognitive impairment (
p
= 0.009, B = −0.289) were associated with willingness to participate in clinical research among individuals with cognitive impairment. Dyadic agreement on willingness to have the individual with cognitive impairment enroll in clinical research was poor to fair (κ = 0.380). Findings suggest that individuals with cognitive impairment with greater trust in health professionals are more likely to agree to clinical research participation. Nurses and other health care providers who counsel individuals with cognitive impairment and their care partners should work to build trusting relationships with participants and be mindful of how increased trust can alter power dynamics between participants and health care professionals.

In this paper we consider fractional-order mathematical model describing the spread of the smoking model in the sense of Caputo operator with tobacco in the form of snuffing. The threshold quantity $ \mathcal{R}_0 $ and equilibria of the model are determined. We prove the existence of the solution via fixed-point theory and further examine the uniqueness of of the solution of the considered model. The new version of numerical approximation's framework for the approximation of Caputo operator is used. Finally, the numerical results are presented to justify the significance of the arbitrary fractional order derivative. The analysis shows fractional-order model of tobacco smoking in Caputo sense gives useful information as compared to the classical integer order tobacco smoking model.

Cardiovascular disease is one of the most challenging diseases in middle-aged and older people, which causes high mortality. Coronary artery disease (CAD) is known as a common cardiovascular disease. A standard clinical tool for diagnosing CAD is angiography. The main challenges are dangerous side effects and high angiography costs. Today, the development of artificial intelligence-based methods is a valuable achievement for diagnosing disease. Hence, in this paper, artificial intelligence methods such as neural network (NN), deep neural network (DNN), and fuzzy C-means clustering combined with deep neural network (FCM-DNN) are developed for diagnosing CAD on a cardiac magnetic resonance imaging (CMRI) dataset. The original dataset is used in two different approaches. First, the labeled dataset is applied to the NN and DNN to create the NN and DNN models. Second, the labels are removed, and the unlabeled dataset is clustered via the FCM method, and then, the clustered dataset is fed to the DNN to create the FCM-DNN model. By utilizing the second clustering and modeling, the training process is improved, and consequently, the accuracy is increased. As a result, the proposed FCM-DNN model achieves the best performance with a 99.91% accuracy specifying 10 clusters, i.e., 5 clusters for healthy subjects and 5 clusters for sick subjects, through the 10-fold cross-validation technique compared to the NN and DNN models reaching the accuracies of 92.18% and 99.63%, respectively. To the best of our knowledge, no study has been conducted for CAD diagnosis on the CMRI dataset using artificial intelligence methods. The results confirm that the proposed FCM-DNN model can be helpful for scientific and research centers.
“Probashi” in Italy. New Destinations: Trends, Origins and Profiles of Bangladeshi Migrants in Padova and Cadoneghe
Authors: Morad Mohammad , Gombač Jure
Published: February 2022

Most of the studies on Bangladeshi migration to Italy have been conducted in cities and towns that already have a relatively long tradition of hosting Bangladeshi communities, such as Rome, Vicenza and Venice. This article focuses on two recent local contexts of Bangladeshi migration to Italy: Padova and Cadoneghe in the Veneto region. The study attempts to answer the following research questions: What are the trends, channels and motivations behind Bangladeshi migration to Padova and Cadoneghe, from which Bangladeshi regions do the migrants originate and what are their cultural, socio-demographic and economic profiles?

Authors: Milharčič Hladnik Mirjam
Published: February 2022

The article presents how Slovenian women emigrants and women immigrants to Slovenia have become an important part of migration studies in Slovenia. The research has focused on gendered migration and revealed different ways of structuring power relationships, social practices and institutions organized according to the gender principle. The article also focuses on methodological development and emphasises the narrative and autobiographical approaches, which brought the voices of women migrants from the past and the present to the analysis of migration, thus enriching various disciplines with personal experiences, individual interpretations and the variety of emotions of women on the move.
Izseljevanje iz Beneške Slovenije v Severno Ameriko na začetku 20. stoletja na podlagi ladijskih potniških seznamov
Authors: Kalc Aleksej
Published: February 2022

Avtor izseljevanje iz Beneške Slovenije v ZDA v prvih desetletjih 20. stoletja analizira na podlagi seznamov ladijskih potnikov, ki so jih v vstopnih pristaniščih sestavljale ameriške oblasti. Razpravlja o dinamičnih in strukturnih vidikih ter pomenu preusmerjanja od kontinentalnih k atlantskim delovnim migracijam, ki so delno ohranjale začasno naravo in konzervativno ekonomsko vlogo, večinoma pa prehajale v trajno naselitev izseljencev v Ameriki. Opozarja na prelomni značaj pojava, s katerim se je začelo stalno izseljevanje iz beneškoslovenskih dolin in prikazuje logistična in socialna stališča ter vlogo družbenih mrež, ki so delovale kot oporni sistem izseljevanja in ohranjanja čezoceanskih vezi.
Med poslom in domoljubjem: Etnična ekonomija in Slovenci zunaj Republike Slovenije
Authors: Žigon Zvone
Published: February 2022

Avtor v članku najprej opiše različne pojavne oblike in značilnosti etničnih ekonomij, nato pa se osredotoči na slovenske skupnosti v zamejstvu in po svetu. Ugotavlja, da so posamezne etnične ekonomije odvisne od socialne in izobrazbene strukture pripadnikov etničnih skupnosti in od zgodovinskega in političnogeografskega konteksta njihovega nastanka. Na podlagi izkušenj sklene, da slovensko ekonomijo in politico čakajo še številni koraki v smeri spodbujanja razvoja in »implementacije« slovenskega modela etnične ekonomije. Opaža spremembe pojma »slovenski izseljenec«, saj ta danes pomeni nekaj drugega kot v preteklosti, to so namreč lahko študent, ki v tujini pridobiva izkušnje, strokovnjak ali pogumni podjetnik.

Introduction: parure, culture et nature — vers une écologie matérielle du vêtement
Authors: Fennetaux Ariane , Mentges Gabriele
Published: February 2022

Interface entre corps individuel et corps social, le vêtement et la mode sont parfois pris comme l’un des signes discriminants de ce qui fait culture et nous distingue du règne animal. Le vêtement permettrait d’opposer nature à culture. À rebours d’une opposition trop franche entre parure, nature et culture, il s’agit au contraire ici d’explorer les multiples intersections — et interactions — entre vêtement, règne animal et civilisations humaines. Plutôt que de constituer une frontière entre les hommes et les autres animaux, le vêtement est vu comme interrogeant leurs liens, l’animal formant un point de passage entre les deux, un point d’entrée permettant un retour critique à la fois sur l’animal que nous sommes, le vêtement que nous avons emprunté aux autres animaux et ce que ce vêtement révèle de notre rapport au monde matériel et vivant. Croisant les interrogations des « animal studies », celles de la culture matérielle et d’un animisme renouvelé par les apports de l’anthropologie, nous posons la question de l’agentivité — des hommes, des choses et des animaux — comme permettant de réfléchir aux rapports entre vêtements et matières animales et ainsi de penser conjointement, plutôt que d’opposer, animalité, matérialité et humanité.
Silks and Skins
Authors: Dulac Anne-Valérie
Published: February 2022

This essay originates from a 2020 interview with Nina Wetzel about her work as costume and set designer for Thomas Ostermeier’s Nuit des rois, which opened in 2018 at the Comédie Française (Paris). It discusses Nina Wetzel’s ironic repurposing of fur and other animal made-objects in relation to Twelfth Night’s obsession with the material dimension of cloth and clothing. Following a brief presentation of the critical history of allusions to textile in the comedy, I inquire into the material properties of all animal-made-fabrics mentioned in the play. This leads me to discuss and contrast the references to silk-based fabrics and those related to skin and fur. By opposing the reflective opalescence of silks to the porous and haptic properties of animal fur and skin, the play commemorates some central late Elizabethan material anxieties, reflected in both sartorial and pictorial self-fashioning. Nina Wetzel’s positively physical and animal take on the costumes and the setting for Ostermeier’s production thus expose and materialise some textile matters only metaphorically alluded to in the text. By bringing to the fore the animal agency in her design, she therefore bares the very origin of the comedy’s variegated fabrics and exposes the way animal fashions reveal and shape the question of human identity in relation to the beastly, social advancement and forms of domination.
“Feather Muffs of all Colours”
Authors: Gernerd Elisabeth
Published: February 2022

The end of the Seven Years’ War (1763) and the acquisition of the fur trade in Canada had an unexpected consequence in British fashion. Despite the increased access to and availability of furs by British furriers, the newspapers noted with disgust that, under the influence of French milliners who had already adapted to their loss of fur supplies, British women of fashion had no taste for furs, only for feathers. The feather muff became the target of the press’s vitriol, an unpatriotic symbol of French sycophantism that was designed to undermine Britain’s victory for which the brave General Wolfe fell.Despite the weighted and charged connotations surrounding the feather muff, its position in eighteenth-century dress and fashion has never before been explored in depth. This article aims to amend that oversight and contextualise the feather muff’s problematic status alongside its material lifecycle and understand the muff as an accessory that could bridge not only the Channel and the globe, but also the disparate worlds of fashion and natural history. Beginning with its notoriously charged appearance in the early 1760s, this article examines the lifecycle of the feather muff in mid eighteenth-century Britain. It first explores the feather muff’s perception in the press as a sartorial French intruder in British fashion. It then establishes how the feather muff was a product of the feather trade, exploring its make and manufacture. Finally, considering the symbolic and emblematic nature of the feather, it places the feather muff within wider narratives of British feather culture, female sociability, and the natural world.
Des insectes, des matières et des femmes :
Authors: Douny Laurence
Published: February 2022

Dans cet article, l'auteure explore la construction sociale de l'apparence chez les femmes marka-dafing de l'ouest du Burkina Faso en partant de la production d’un textile traditionnel appelé tuntun dont la composante principale est la soie sauvage, une matière rare et précieuse. En analysant les procédés techniques utilisés par ces femmes pour transformer les cocons d'abord en fils puis, avec l'aide de tisserands, en pagnes et foulards, l'auteure s’interroge sur la nature et les significations attribuées à cette matière aux caractéristiques mystiques produite par des chenilles non-domestiquées. Des affinités matérielles entre les femmes, la soie et les esprits émergent au cours du processus complexe de transformation de la matière qui permet de révéler sa brillance. La soie, par l’intermédiaire du corps qui porte le pagne, matérialise ces relations et sa brillance permet de connecter le monde visible à celui de l’invisible. Dotée d’agentivité matérielle, la brillance contribue également à légitimer les messages qui sont tissés dans le textile.
Which morphologies for “inclusion in urbanity”? Exploring practices along the Steenweg

Le Steenweg, un axe est-ouest traversant le centre métropolitain de Bruxelles, est appelé à jouer un rôle clé dans la mise en œuvre de la vision de la mobilité future de la ville. En outre, une récente recherche [De Visscher et al., 2020] tend à indiquer que cet axe présente pour Bruxelles des enjeux importants en matière d’inclusion sociale. En prévision de futurs réaménagements, le présent article examine plus avant cette dernière hypothèse, en ouvrant des pistes de réflexion sur les possibilités d’« inclusion dans l’urbanité » le long du Steenweg. À partir de la proposition de Remy en faveur de la communication dans la distance [Remy, 2020 [1990]] et selon une approche socio-spatiale, l’article se concentre sur les morphologies qui contribuent à rendre possible un accès inclusif au tissu social et spatial de l’urbanité pour des groupes divers. À cette fin sont exposés les résultats d’une recherche exploratoire sur un type de morphologie présent le long du Steenweg : les galeries commerciales. L’article propose ensuite des pistes pour approfondir la réflexion sur les morphologies qui favorisent la communication dans la distance le long de cet axe en recensant tous les espaces accessibles au public au-delà des limites habituelles de l’espace public à ciel ouvert du Steenweg.

Cet article présente une méthode exploratoire mobilisant la photographie comme outil d’analyse des dynamiques paysagères dans un espace singulier, celui de la Ceinture verte d’Île-de-France. L’usage de la photographie est pensé comme complémentaire d’une approche cartographique, conduite à l’échelle régionale. Des transects sont définis suivant des segments radiaux traversant l’épaisseur de la Ceinture verte. La base de données de clichés photographiques constituée permet d’analyser finement les logiques d’organisation paysagères, de se forger une expérience du terrain et d’amener une dimension sensible qui renseigne sur l’accès aux espaces non bâtis dans un espace à dominante périurbaine.
Mise en marché des petits pélagiques côtiers au Sénégal : formes de valorisation et enjeux autour de la ressource
Authors: Dème El hadj Bara , Dème Moustapha
Published: February 2022

L’objectif de l’article est d’analyser les enjeux liés à la mise en marché des pélagiques côtiers au Sénégal. Les informations disponibles montrent qu’en termes de conditions nutritionnelles et de lutte contre la pauvreté, les petits pélagiques côtiers ont une importance stratégique au Sénégal. Toutefois, l’émergence de nouveaux usages non alimentaires et la tendance des exportations des pélagiques (croissance de la demande mondiale) menacent la sécurité alimentaire nationale et la durabilité des stocks. Contrairement aux démersaux côtiers, ou des contrats d’exclusivité sont conclus entre pêcheurs, mareyeurs et usiniers, pour les pélagiques côtiers les mécanismes du marché prévalent, le poisson débarqué est vendu quotidiennement au plus offrant. Face à des marchés extérieurs plus attractifs, la disponibilité apparente de produits halieutiques pour les populations sénégalaises est conséquemment en baisse.
Solving a Real Case of Seafaring Staff Scheduling Problem Using Cuckoo Optimization Algorithm
Authors: Koubaa Marwa , Ammar Mohamed Haykal , Beji Noura
Published: February 2022

This work deals with Human Resource Scheduling Problem (HRSP) where fairness is a very important factor when assigning different shifts to the seafaring teams. This type of problem is part and partial of the NP-hard problems category. We propounded to work out this Seafaring Staff Scheduling Problem (SSSP) using one of the population-based meta-heuristics called Cuckoo Optimization Algorithm (COA), one of the newest, most robust and most popular bio-inspired algorithms. rnAffording schedules that ensure an enhanced staff rest to the company compared to the traditionally used ones was the main objective of the paper. The results indicate that this method outperforms the traditional one in solving this NP -hard problem. In addition, they prove the COA performance in the improvement of the objective function value compared to the previously proposed methods in the literature namely GRASP and ABC. Finally, the use of the COA in scheduling also increased the total posts to be assigned by one compared to the ABC method.
An Efficient Constructive Heuristic for the Cutting Stock Problem Applied in a Foam Mattress Industry
Authors: Baazaoui Mariem , Elleuch Souhir , Kamoun Hichem
Published: February 2022

The cutting and packing problem belongs to the combinatorial optimization problems; it covers a wide range of practical cases in industries. The present paper investigates a new real world problem needs to be solved through a daily operations of cutting foam blocks in an industrial company. The problem is considered as one of non-classical problems in the cutting and packing area. It represents a variant of the three dimensional Cutting Stock Problem. The originality of the studied problem is indicated by a specific set of constraints related to the production process and the cutting ways. A constructive heuristic was developed to provide cutting patterns in advance. All possible combinations established from the ways of cutting right rectangular prisms from foam blocks define the cutting patterns. This heuristic performs well and shows promising results in reasonable computational times to provide efficient cutting plans in order to reduce the total material loss.
Canon and Process in the 3D Modeling of Human Anatomy
Authors: de Azevedo Hugo , Araújo António B.
Published: February 2022

The authors argue that the concept of the anatomical canon is not just an arbitrary standard of anatomical beauty but an indispensable mnemonic tool for the artist. The authors further argue that the canon is most relevant when adapted to a specific artistic process and tools, and in particular must be updated to the requirements of the digital tools of 3D modeling. A proposal of such a canon is discussed, as well as the process of its synthesis from standard 3D primitives and its artistic applications.
Biomimicry and Art
Authors: Leote Rosangella
Published: February 2022

The concept of biomimicry has been used in various fields, from nanotechnology to machine intelligence, for various purposes, inspired by natural processes and organisms. The main application of biomimicry has been to produce artifacts and ideas from what we can know about what nature has already done. Many artists have devoted themselves to the development of works with poetics of hybridization and mimicry. How close would they be to biomimicry? Or would they be bioinspiration? This discussion is the starting point to present the “VIRIDIUM” project, which focuses on the development of semi-autonomous and translucent 3D-printed sculptures. In addition to the biomimicry (biomimetics), bioinspiration, and Darwinian evolution concepts, the concept of artification is also addressed as a possible model of understanding the poetic process, both in "VIRIDIUM" and in the works of the artists listed.
Analysis and Prediction of Meteorological Data Based on Edge Computing and Neural Network
Authors: Wang Jianxin , Li Geng
Published: February 2022

In this work, aiming at the problem of missing element values in real-time meteorological data, we propose a radial basis function (RBF) neural network model based on rough set to optimize the analysis and prediction of meteorological data. In this model, the relative humidity of a single station is taken as an example, and the meteorological influencing factors are reduced by rough set theory. The key factors are used as the input of RBF neural network to interpolate the missing data. The experimental results show that the interpolation effect of the model is significantly higher than that of the linear interpolation method, which provides an effective processing method for the lack of real-time meteorological data, and improves the analysis and prediction effect of meteorological data.
Spectrum Allocation Scheme for IoMT Devices Using Game Theory
Authors: Epuri Sowmya
Published: February 2022

There are a lot of challenges like versatility, network, receptiveness, accuracy, etc… when working on an internet-connected device because of the wide usage of them across the global. Currently there is a huge demand for reliable ways to connect to wireless. Same was conveyed as part of multiple observations and many have explained how spectrum sensing helps to allocate dynamically the unlicensed frequency bands for IoT applications reducing traffic and enabling the IoT technologies. Goal of Cognitive radio is to use the unadopted spectral spaces called spectral holes. A non-cooperative game theoretic strategy is employed to study the same. Also, the formulation of a utility function in terms of spectral usage rate of the users in a CR network. For obtaining the spectral usage rate, a 2-D continuous-time Markov Chain (CTMC) scenario is proposed to obtain the strategy for the users of CR in order to choose the appropriate spectral gaps. The parameters such as percentage utilization of spectrum by varying parameters like Traffic, No. of users and Data Burst rates are studied.

In this article, we examined the electrical characteristic of proposed new device structure, Wrapped Channel Field Effect Transistor (WCFET). Results of WCFET have been analyzed using Atlas 3-D simulator. WCFET shows better transfer characteristics with ON-current ION of ~10-6A and leakage current IOFF of ~10-16 A. Optimization of device characteristics has done with doping concentration (ND), gate work function (ΦG) and spacer dielectric. Impact of gate length and semiconductor film thickness variation on drain current, subthreshold slope (SS) and DIBL are also investigated. Further, effects of various gate dielectric materials such as SiO2, Si3N3, HfO2 and TiO2 are examined w.r.t. switching characteristics of WCFET. To validate of device compatibility with power supply scaling, we inspected full range variation of VDS ≈ (0.05V-to-0.7V) on transfer characteristics.
The Application of a Socio-Economic Indicator for Calculating the Bandwidth of a Backbone in a WAN
Authors: Ahmedi Basri H.
Published: February 2022

In a regional network, the graph branches that describe it are not loaded equally with data traffic. A branch that is loaded with traffic will depend on: the number of users in both nodes of the graph, the number of paths that pass through that branch which are defined by the algorithm for finding the shortest path, the position of the branch in the network as well as the position of WAN in other neighbors’ networks. The traffic on the branches that connect the nodes of a network is constantly changing. It is important to know the maximum load of a branch in order to adapt to the demand so that there are no communication barriers. The calculation of data traffic in these branches is possible to be calculated and to know the maximum traffic limit in the respective branches. The branches that are busiest with data traffic represent the backbone of the Network. The calculation of the bandwidth of the branch is affected not only by the number of users but also by their structure. In this paper, bandwidth calculation on a main branch in a graph is done through a case study using SEI.

Beginning with the advent of the Internet in the mid-nineties, e-commerce has started to be a viable alternative way of shopping for the consumers worldwide. Without doubt, it could be said that e-commerce has become indispensable in our lives. Recent global pandemic has increased e-commerce adoption by elderly people even further as the sole way of buying their needs. This paper studies the direct and indirect effects of product portfolio in B2C e-commerce web sites on customers’ purchase intention through perceived value and brand loyalty. SEM method was used to test the hypotheses. The results of the study indicate that product portfolio does not have a direct effect on purchase intention. However, it does have an indirect influence on purchase intention through perceived value and brand loyalty. As a result, this study validates the extant literature by confirming the mediating role of brand loyalty between the relationship between perceived value and purchase intention. The findings obtained are believed to provide significant contribution to the related e-commerce literature.
Identification and Evaluation of Factors Influencing the Quality of Elderly Services Supply Chain Based on DEMATEL-ISM-TOPSIS Method
Authors: He Jingshi
Published: February 2022

With the intensification of aging, the importance of the elderly care service supply chain is gradually being recognized by people. A systematic analysis of the quality of elderly care services from the perspective of the supply chain will help provide decision-making reference for improving the quality of elderly care services. The evaluation index system of elderly care services` quality is constructed from the perspective of the integrated SCOR model. The integrated DEMATEL-ISM-TOPSIS method is proposed for evaluation and analysis. The research pointed out the surface and deep influencing factors as well as the weight of each evaluation factor of the elderly care services` quality. The interpretative structure model was constructed to point out the hierarchical relationship and the principal-subordinate logical relationship of each evaluation factor. The weight of the quality factors of elderly care services was obtained, and the applicability of the model and method was verified by an evaluation case of elderly service institutions.

Published: February 2022

Many developing nations, such as Palestine, implemented PPP (public-private partnership) to fulfill the increasing needs for public services and facilities. Nonetheless, PPP projects have numerous risks which influence each other and can cause project failures. Unfortunately, current studies related to the PPP risk association have not provided adequate details. This paper tries to fill the literature gap by proposing a practical approach in analyzing the relationship among PPP risks. First, the research identifies risk for PPP projects in the Palestinian construction industry by integrating the interviews and literature review. Next, this study reflects the associations among the risks and reveals the failure instruments of PPP projects using FISM (fuzzy interpretative structural modeling). Besides, this paper uses MICMAC (matrix impact cross-reference multiplication applied to a classification) and FISM method to discover and finalized the 19 crucial risk elements. The MICMAC-FISM approach reckons the fuzzy of the PPP risk association and enhances upon previously published works.

Idiopathic pulmonary fibrosis (IPF) is an irreversible, age-related diffuse parenchymal lung disease of poorly defined etiology. Many patients with IPF demonstrate distinctive lymphocytic interstitial infiltrations within remodeled lung tissue with uncertain pathogenetic relevance. Histopathological examination of explant lung tissue of patients with IPF revealed accentuated lymphoplasmacellular accumulations in close vicinity to, or even infiltrating, remodeled lung tissue. Similarly, we found significant accumulations of B cells interfused with T cells within remodeled lung tissue in two murine models of adenoviral TGF-β1 or bleomycin (BLM)-induced lung fibrosis. Such B cell accumulations coincided with significantly increased lung collagen deposition, lung histopathology, and worsened lung function in wild-type (WT) mice. Surprisingly, B cell–deficient µMT knockout mice exhibited similar lung tissue remodeling and worsened lung function upon either AdTGF-β1 or BLM as for WT mice. Comparative transcriptomic profiling of sorted B cells collected from lungs of AdTGF-β1– and BLM-exposed WT mice identified a large set of commonly regulated genes, but with significant enrichment observed for Gene Ontology terms apparently not related to lung fibrogenesis. Collectively, although we observed B cell accumulations in lungs of IPF patients as well as two experimental models of lung fibrosis, comparative profiling of characteristic features of lung fibrosis between WT and B cell–deficient mice did not support a major involvement of B cells in lung fibrogenesis in mice.
Interatrial Conduction Block in an Obstructive Sleep Apnea Patient
Authors: Antonopoulos Athanassios
Published: February 2022

Obstructive sleep apnea (OSA) is an important sleep disorder and is associated with increased cardiovascular morbidity and mortality. Several recent studies have demonstrated an association OSA and atrial fibrillation (AF). Therefore, it is of great importance understanding the pathophysiological substrate and the interaction between OSA and AF. Moreover, it is well accepted that interatrial block (IAB), evaluated not only by the P-wave duration but also by the P-wave morphology, has the potential to give information about the anatomical substrate predisposing to AF. OSA and AF share many risk factors and comorbidities, including older age, male gender, obesity, hypertension, heart failure, and coronary artery diseases. IAB is defined when the P-wave is ≥120 ms which signifies excessive time for sinus impulses to conduct from the right atrium to the left atrium and may predict future AF events. Accordingly, recent studies have suggested that OSA is associated with atrial functional and structural remodeling which indeed are associated with increased risk of AF. We speculate that IAB, a known factor to predict future AF episodes, may associate with OSA and contribute to the development of arrhythmic events. In the present case, the report presents a woman with OSA and IAB on the surface electrocardiogram (ECG)automatic P-wave analysis and some short episodes of AF in the external event recorder monitoring.

We present the case of a 38-year-old male with a history of acute chest pain associated with electrocardiographic ST-segment elevation and levels of myocardial damage markers. Few studies have evaluated chest pain and elevated troponin T during subacute thyroiditis. To the best of our knowledge, this is the reported case of myopericarditis associated with increased thyroid hormones in the bloodstream and accompanied by a significant increase in troponin T and cardiac magnetic resonance imaging findings of myopericarditis during the acute phase of subacute thyroiditis.

Published: February 2022

Transcatheter aortic valve implantation (TAVI) for bicuspid aortic valve stenosis can pose several technical challenges including difficult valve crossing. We report the case of a 77-year-old woman undergoing transfemoral TAVI for symptomatic severe bicuspid aortic stenosis. It proved impossible to cross the bicuspid aortic valve retrogradely despite the use of multiple catheters and wires and attempts by two interventional cardiologists. We describe a novel approach to antegrade crossing, through a transseptal access, to permit retrograde implant of prosthesis.

Published: February 2022

This review aims to explore the status of heart failure (HF) practice and research in Oman. Extensive search of databases (Arab World Research Source, EBSCOhost, Medline, and Google Scholar) yielded eight published literatures in the last two decades in Oman. The escalation of HF among older adults in Oman has been documented across the two decades. Ischemic heart disease continues to dominate as the cause for HF among the Omani population. Recent researchers have highlighted that acute coronary syndrome and noncompliance with medications are factors which precipitate an acute HF. One-year follow-up of HF patients in Oman has estimated their mortality rate at 25%. Our knowledge of HF is very limited by the few published research and data sets. However, the prevalence of HF is increasing, and is expected to dramatically increase with the rise in the Omani population in hypertension and diabetes. More research is needed in the area of HF on the Omani population.
