Published: November 2022

This study is aimed at testing the significance of Brownian movement and thermophoresis dispersion on MHD Casson nano liquid limit layer stream past a nonlinear slanted permeable extending surface, with the impact of convective limits and warm radiation with a synthetic response. Nonlinear ODEs are gotten from overseeing nonlinear PDEs by utilizing good comparability changes. The amounts related to building angles, for example, skin grating, Nusselt and Sherwood numbers alongside different effects of factors from the material on the speed and temperature, are outlined. Numerical consequences of the current investigation are acquired through the Runge-Kutta Fehlberg strategy alongside the shooting procedure and in a constraining sense are diminished to the distributed outcomes for a precision reason.

Non-Newtonian fluid model was created against the Newton’s Law of viscosity where the viscosity is no more constant and dependent on the shear rate. The existing such fluid can be found in many industrial claims especially in food manufacturing, lubrication, biomedical flows and oil and gas. Besides, the used of non-Newtonian fluid occurs in mining industry where the slurries and muds are often handled. There are many models on non-Newtonian fluid available in literature where some of them capture the specific properties. The Reiner–Philippoff (RP) fluid model is considered in this endeavour due to the capabilities of the model which can be acted in three different family of fluid which are viscous, shear thickening and the shear-thinning. Mathematical model is constructed using continuity, momentum and energy equations where in form of partial differential equations (PDEs). The complexity of the proposed model is abridged by deduced the equations into ordinary differential equations (ODEs) by adopting similarity variables before the computation is done by bvp4c function drive in MATLAB software. To ratify the validity of the proposed model as well as numerical outputs, the comparative study is performed and it found to be in very strong agreement under limiting case where the present model is condensed to be identical with the reported model previously. The consequences of pertinent parameters on fluid’s characteristics are analyzed in details through the plotted graphic visuals and tabular form.
Flow of Viscoelastic Fluid with Microrotation at a Boundary Layer Flow of a Horizontal Circular Cylinder

Published: November 2022

In this study, the dynamics of the non-Newtonian viscoelastic fluid with microrotation at a boundary layer of a horizontal circular cylinder is investigated. For this case, Lorentz force is induced by external magnetic field positioned at right angle of the fluid flow, hence the magnetohydrodynamic effect is embedded in the momentum equation of the proposed model in addition to other governing parameters. The constitutive equations are converted to dimensionless form along with the associated boundary conditions before the resulting partial differential equations are solved using finite difference technique in Fortran programming. Results are validated before the velocity and microrotation profiles are examined and the effects of material, viscoelastic and magnetohydrodynamic parameter on the flow is discussed.

A Kabuki Pose in Sculptures of Auguste Rodin
Authors: Doma Petra
Published: November 2022

Hanako (Ōta Hisa, 1868–1945) was an insignificant member of a small Japanese theatrical troupe when she was discovered by the well-known dancer, Loïe Fuller, who after seeing Hanako’s death scene, decided to become her impresario. Thereafter, Fuller organised each of Hanako’s European tours and wrote for her many Japanese-style dramas that always ended with the cruel but utterly expressive death of the protagonist. Hanako met Auguste Rodin, the famous sculpture, at the Marseille Colonial Exhibition in 1906. The master was fascinated by Hanako’s performance and tried to sculpt the ‘death face’ that she expressed during her death scenes. This face, with a weird expression, was most probably a nirami, which is a type of mie pose in kabuki theatre. Rodin created numerous busts and faces from different materials trying to capture the emblematic moment when Hanako saw death. The present paper examines the short but interesting period of Hanako’s Western career, focusing on her meeting with Rodin. I use their story as a unique and symbolic illustration of Japanese artists’ efforts to transform themselves and their art to ‘match’ the Western eye and of the ways in which the West was looking for verification of its preconceptions of the ‘strange’ and ‘exotic’ East in the early 1900s.

Published: November 2022

The paper aims to analyse the changing economic structure and the trends of the digitalization amplification through the prism of a dynamic multi-criteria model, assessing the strategic perspective by pivoting digitalization in the strategic equation. The main objectives of the research cover the context of vulnerability across the EUSDR countries, the solutions from the literature review and the definition, testing and implementing of a new dedicated model. The model takes into account regional indicators, reported by Eurostat. Statistical analysis procedures and methods were applied in order to capture the expected disparities under the impact of the pandemic, as well as harmonization with European Strategy for Danube Region (EUSDR) – specific impact indicators. The analysis uses la latest official statistical data from Eurostat. The importance of this scientific approach lies in the fact that the results are applicable to the wider region, the vast majority of the Danube states being EU members (9 states), 3 candidate states and 2 potential candidate states in the new geo-political and military context. States that are not yet EU members have regional and cross-border cooperation agreements with the EU. Moreover, the region itself has reacted in a unified way to the challenges of the economic and pandemic crises, the study being conducted over the period 2004–2020. In addition, EU Member States have additionally benefited from European emergency allocations to counter the effects of the global economic crisis and stem the spread of the pandemic. We used empirical and analytical methods, starting with the study of literature, data collection and consolidation of the database, its homogeneity and the application of modelling procedures. The major key findings are focused on the existence of a strong connection between investment effort, labour skills, sustainable development and the digital economy able to face new global and regional challenges. The policy implication of this research consist in offering viable elements capable of assisting regional decision-makers in adopting topical measures on digitisation and reconfiguring strategic regional connections to maintain a sustainable direction for the EUSDR. The recommendations from this study imbraca forma some directions for action related to labour high skills, digitalization, R&D investment and e-commerce.

We present mapping results of two prestellar cores, L1544 and L694-2, embedded in filamentary clouds in C18O (3–2), 13CO (3–2), 12CO (3–2), HCO+ (4–3), and H13CO+ (4–3) lines with the James Clerk Maxwell Telescope to examine the role of the filamentary structures in the formation of dense cores in the clouds, with new distance estimates for L1544 (

pc). From these observations, we found that the nonthermal velocity dispersion of two prestellar cores and their surrounding clouds is smaller than or comparable to the sound speed. This may indicate that the turbulence has already been dissipated for both filaments and cores during their formation time. We also found a λ/4 shift between the periodic oscillations in the velocity and the column density distributions, implying the possible presence of gravitational core-forming flow motion along the axis of the filament. The mass accretion rates due to these flow motions are estimated to be 2–3 M
⊙ Myr−1, being comparable to that for Serpens cloud but much smaller than those for the Hub filaments, cluster, or high-mass forming filaments by 1 or 2 orders of magnitude. From this study, we suggest that the filaments in our targets might be formed from the shock compression of colliding clouds, and then the cores are formed by gravitational fragmentation of the filaments to evolve to the prestellar stage. We conclude that the filamentary structures in the clouds play an important role in the entire process of formation of dense cores and their evolution.
Witnessing a Galaxy Cluster Merger with JWST and a Chandra X-Ray Temperature Map
Authors: Alden Brian C. , Burns Jack O.
Published: November 2022

The first James Webb Space Telescope (JWST) image released was of galaxy cluster SMACSJ0723.3-7327, a lensing cluster at z = 0.39 showing detail only JWST can provide. While the majority of the focus has been on the brilliantly lensed galaxies at redshifts far beyond it, there is more to the story than it being just a lensing cluster. The Chandra X-ray temperature map tells a tale of a merging cluster with a significant subcluster leaving a wake in the intracluster medium (ICM). This paper presents a high fidelity temperature map of SMACSJ0723.3-7327 using adaptive circular binning, overlaid with the JWST image, showing clear signs of merger activity. As the ICM extends well past the boundaries of the JWST imagery, and no low-frequency radio observations are yet published, a fuller story of this cluster remains to be told. This new X-ray temperature map reveals new details of a moderately distant actively merging cluster.
Release and follow-up of a rehabilitated two-toed sloth (Choloepus hoffmanni) in a tropical dry forest in Ecuador
Authors: Villalba-Briones Ricardo , Jiménez Edwin R. , Monros Juan S.
Published: November 2022

We present the first records of the post-release follow-up and monitoring of a rehabilitated two-toed sloth (Choloepus hoffmanni) as well as freezing behavior and an inferred antagonistic interaction for this species. Two-toed sloths are nocturnal and arboreal mammals whose survival relies on their capability to remain undetected by predators. Nevertheless, in the Guayas province of Ecuador, they are among the most common mammal species in rehabilitation centers. The liberation of animals back to the forest is the main goal of rehabilitation, while the follow-up of post-release human support of animals facilitates their re-establishment in their natural habitat. Follow-up, direct observation, and Bluetooth-based monitoring of the two-toed sloths secured the survival of this species in this part of Ecuador. The range of detectability of the device used indicates its suitability for tracking low-mobility animals. After the first five days, the number of trees used per day increased, and 19 trees within 1152 m2 were visited. Daylight and movement time range showed a correlation towards detectability. The follow-up effort allowed for keeping the two-toed sloth safe for 10 days after release. Due to the difficulty monitoring nocturnal animals, economic constraints in conservation, accessibility, and safety of the animals, biodegradable Bluetooth-based backpacks are recommended to ease the location of the animal and support its survival in the wild.
La recherche et les études en droit de la défense : du centre et de la revue Droit et Défense à l'AFDSD
Authors: Gohin Olivier
Published: November 2022

Résumé Une vie universitaire bien remplie requiert, en France, une grande abnégation : avoir à faire beaucoup pour obtenir peu à partir de pas grand-chose. Tel est le cas, en particulier, pour celles ou ceux qui se consacrent intellectuellement, par vocation et profession, aux questions de souveraineté même si la conjoncture politique, nationale et internationale, remet cette thématique à l'ordre du jour. La présente « carte blanche » retrace les nombreuses difficultés de la reprise et du développement du droit fort ancien, mais longtemps occulté, de la sécurité et de la défense. Sa relance remonte précisément au Code de la défense de 2004 qui englobe « la politique de défense » dans « la stratégie de sécurité nationale » (art. L.1111-1) et au Livre blanc sur la défense et la sécurité nationale de 2008, terminologie, d'ailleurs, plus organique que fonctionnelle. À travers une expérience professionnelle conduite sur trente ans, entre 1992 et 2022, il importe d'établir la continuité des considérables efforts déployés, dans l'Université française, en faveur de ce droit qui, comme le droit des collectivités territoriales, par exemple, n'est pas nouveau, mais à renouveler, avec l'appui nécessaire des institutions publiques pour son accréditation et sa diffusion. Or, il est permis d'espérer qu'il en soit enfin ainsi : la multiplication récente des travaux et des formations, et donc des recrutements ou des promotions ou encore des détachements ou autres coopérations réciproques d'intervenants et d'étudiants dans ce vaste champ de recherche et, dès lors, d'enseignement, va nettement en ce sens.
L'excès de normes : le militaire pris en étau ?
Authors: Videlin Jean-Christophe
Published: November 2022

Résumé Comme de nombreux acteurs publics et privés, l'inflation normative peut être contestée au sein des armées. Elle serait source de contraintes excessives, empêchant l'efficacité de l'action. Il est vrai que les normes sont de plus en plus nombreuses, mais cette croissance a plusieurs origines. L'inflation normative ne s'explique pas, de fait, par la seule volonté de l'État. Le juge y contribue, tout comme le fait pour la France d'être pleinement intégrée dans la société internationale. Par ailleurs, nombre de normes se font au bénéfice des militaires. Ainsi, s'il ne fait pas de doute que le droit de la défense nationale connaît un accroissement quantitatif normatif, il est autant un avantage qu'une contrainte pour les armées.
La libre circulation du militaire dans l'Union européenne
Authors: Daniel Élise , Kieffer Maeve
Published: November 2022

Résumé S'il n'existe pas encore de véritable union militaire au sein de l'Union européenne, l'intérêt de l'Union pour le fait militaire s'est sans contexte accru ces dernières années. Et la conjoncture géopolitique actuelle semble propice au renforcement de cette tendance. Certains pourraient le déplorer, estimant que l'objectif de paix à l'origine de la construction européenne s'accommode difficilement d'une circulation des chars dans l'Union. Et pourtant, la circulation libre d'un char allemand sur le territoire français, sans que l'existence d'un acte de guerre effleure l'esprit des populations, ne serait-elle pas un puissant symbole de paix ?
Panem et circenses . Les rois finançaient-ils les spectacles sous l’Ancien Régime ?
Authors: Serre Solveig , Kniaz Alix , Soleiman François
Published: November 2022

L’Ancien Régime n’a pas développé un soutien financier systématique pour les arts. Cependant, l’octroi de privilèges à certaines institutions resserre durablement les liens existants entre le politique et la Culture. Les évolutions postérieures, de la Révolution française à nos jours, en portent d’ailleurs la trace. En se concentrant sur l’exemple de l’Opéra de Paris, cet entretien révèle comment les productions culturelles, tantôt disciplinées, tantôt subversives, ont suscité l’attention des puissants et de leurs détracteurs durant cette période.
Soigner les « exclus » dans les centres et réseaux de santé : des formes d’institutionnalisation différenciées de l’assistance socio-médicale en médecine de ville
Authors: Aranda Mauricio
Published: November 2022

La loi de lutte contre les exclusions de 1998 formalise l’existence, au niveau national, des permanences d’accès aux soins de santé ( pass ) à l’hôpital. Depuis, ses professionnels assurent des consultations médicales, ainsi qu’un travail social d’ouverture des droits sociaux, auprès de la patientèle sans couverture sociale et sans ressources. Ce modèle articulant dimensions sanitaire et sociale dans la prise en charge de personnes éloignées du système de santé a récemment été repris au niveau local. En 2013, l’Agence régionale de santé d’Île-de-France a mis sur pied l’expérimentation des pass ambulatoires. Elle a décidé de les placer dans des institutions de soins primaires situées en dehors de l’hôpital, en l’occurrence des centres municipaux de santé et des réseaux de santé associatifs. Sachant que ces structures ont été choisies en raison de leur mobilisation préexistante sur le sujet et que les pass ambulatoires sont une transposition de ce qui se passe à l’hôpital, cet article s’interroge sur l’institutionnalisation de l’assistance socio-médicale produite par cette expérimentation. Si cette dernière fait apparaître ou renforce la dimension sociale de la prise en charge des patients, en permettant la création de postes qui lui sont dédiés, elle ne contribue pas à l’instauration d’un personnel médical supplémentaire – parfois nécessaire dans ces structures. Ainsi, cette expérimentation dans les centres et réseaux de santé se traduit par des formes d’institutionnalisation différenciées de la prise en charge de leur patientèle.
The global attractive sets and synchronization of a fractional-order complex dynamical system
Authors: Lin Minghung , Hou Yiyou , Al-Towailb Maryam A. , Saberi-Nik Hassan
Published: November 2022

This paper presents a chaotic complex system with a fractional-order derivative. The dynamical behaviors of the proposed system such as phase portraits, bifurcation diagrams, and the Lyapunov exponents are investigated. The main contribution of this effort is an implementation of Mittag-Leffler boundedness. The global attractive sets (GASs) and positive invariant sets (PISs) for the fractional chaotic complex system are derived based on the Lyapunov stability theory and the Mittag-Leffler function. Furthermore, an effective control strategy is also designed to achieve the global synchronization of two fractional chaotic systems. The corresponding boundedness is numerically verified to show the effectiveness of the theoretical analysis.

Published: November 2022

This paper presents the problem modeled using Caputo fractional derivatives with an accurate study of the MHD unsteady flow of Nanofluid through an inclined plate with the mass diffusion effect in association with the energy equation. H2O is thought to be a base liquid with clay nanoparticles floating in it in a uniform way. Bousinessq's approach is used in the momentum equation for pressure gradient. The nondimensional fluid temperature, species concentration, and fluid transport are derived together with Jacob Fourier sine and Laplace transforms Techniques in terms of exponential decay function, whose inverse is computed further in terms of Mittag-Leffler function. The impact of various physical quantities interpreted with fractional order of the Caputo derivatives. The obtained temperature, transport, and species concentration profiles show behaviours for $0 < \mathtt{α} < 1$ where $\mathtt{α} $ is the fractional parameter. Numerical calculations have been carried out for the rate of heat transmission and the Sherwood number is swotted to be put in the form of tables. The parameters for the magnetic field and the angle of inclination slow down the boundary layer of momentum. The distributions of velocity, temperature, and concentration expand more rapidly for higher values of the fractional parameter. Additionally, it is revealed that for the volume fraction of nanofluids, the concentration profiles behave in the opposite manner. The limiting case solutions also presented on flow field of governing model.

Published: November 2022

In this paper, we investigate the semi-analytical solution of Kaup-Kupershmidt equations with the help of a modified method known as the new iteration transformation technique. This method combines the Yang transform and the new iteration technique. The nonlinear terms can be calculated straightforwardly by a new iteration method. The numerical simulation results have been presented to demonstrate the reliability and validity of the proposed approach. The result confirms that the suggested technique is the best tool for dealing with any nonlinear problems arising in technology and science. In addition, in terms of figures for varying fractional order, the physical behavior of new iteration transformation technique solutions has been shown and the numerical simulation is also exhibited. The solutions of the new iteration transformation technique reveal that the projected technique is reliable, competitive and powerful for studying complex nonlinear fractional type models.

The paper analyzes labour market services, as one of the labor market interventions. Labour market services represent all activities of the public employment service and other publicly funded services for jobseekers, which include counseling the unemployed, mediation between workers and employers, informing, monitoring the unemployed and sanctioning in the case of non-compliance, and are considered to be the most cost-effective labour market intervention. Although in recent decades the main focus of labour market policy has been on measures of active labour market policy (such as training or employment incentives), in recent years, with the actualization of the activation concept, labour market services have taken their turn. This paper presents the main features, development, advantages and disadvantages of this intervention in the Republic of Croatia and the opinion of the main actors of this intervention, the Employment Advisors of the Croatian Employment Service. Key words: labour market services, counseling the unemployed, labour market, Croatia.

Effectiveness of group metacognitive therapy on recovery indicators in Muslim female drug abusers: Evidence from Afghanistan
Authors: Ziaee Seyedeh Soleil , Karimi Naser
Published: November 2022

Objective: Substance abuse is associated with a plethora of issues and harmful outcomes. It contributes to antisocial behavior and psychological disorders. The present study evaluated the effectiveness of metacognitive group therapy (MCGT) on recovery indicators in Muslim female drug abusers in the Herat Province of Afghanistan.Methods: In this study, Muslim female drug abusers (N=30, mean age 38.15 years, 100% female, 100% Afghan) were randomized to group metacognitive therapy (MCGT) or treatment as usual (TAU). The MCT group received six sessions of MCT in addition to conventional treatment. The TAU group received only conventional treatment. All participants completed a demographic questionnaire and Metacognition Questionnaire, Beck Anxiety Inventory, Beck Depression Inventory-II, Drug Use Evaluation Questionnaire, Personal Concerns Inventory, Motivational Structure Questionnaire, and Situational Confidence Questionnaire (SCQ). Data were collected at baseline and at the 3-month follow-up sessions. Results: Compared with TAU, MCT reduced anxiety, depression, drug use evaluation, and personal concerns, as well as improved motivational structure, situational confidence, and metacognitive beliefs. Conclusions: It seems that MCT may be an essential addition to methadone maintenance therapy.This study strongly suggests that MCT is an effective treatment for improving Muslim drug abusers’ recovery indicators, but only in cases of mild to moderate severity. For persons with severe substance abuse, additional treatment may be necessary.
Les réfugiés politiques polonais dans l’Ouest de la France et le projet d’une expédition au Portugal en 1833
Authors: Tarkowska Ewelina
Published: November 2022

L’idée de créer une légion polonaise, composée de réfugiés polonais venus en France après 1831, et de la mettre au service du Portugal pendant la guerre civile, est un sujet très intéressant du point de vue de l’histoire de la Pologne, de la France et du Portugal. Les Polonais pouvaient se rassembler sur la côte ouest de la France. Ils étaient présents principalement sur Belle-Île, à Nantes, dans les villes du département des Côtes-du-Nord, à La Rochelle. Les autorités locales en France surveillèrent l’organisation du départ des Polonais vers le Portugal pendant plus d’un an. Le gouvernement français a officieusement soutenu le projet du général Józef Bem en raison de la situation politique instable à l’intérieur du pays. Cependant, la conjoncture internationale défavorable, les conditions de la convention polono-portugaise difficiles à mettre en œuvre et la discorde au sein de l’émigration polonaise en France ont conduit à l’échec de ce projet.
Qu’est-ce qu’un drapeau régimentaire ?
Authors: Le Bloas Alain
Published: November 2022

Qu’est-ce qu’un drapeau régimentaire ? L’article cherche à répondre à cette question pour la deuxième partie du xixe siècle, période de son apogée tant dans l’armée que dans la société française. Il le fait à partir d’un drapeau de zouaves. Cette biographie vexillaire montre que durant cette période le drapeau conserva des invariants, mais qu’il fut aussi après 1870 rechargé et en partie recomposé. Il resta toujours un signe déployé au combat et un symbole affectif entretenant l’identité régimentaire. Si, sous le Second Empire, cette dernière était particulièrement valorisée, la République en fit le symbole à la fois de la patrie et du collectif combattant, emboîtés telles des gigognes. La valorisation de l’emblème se poursuivit jusqu’à sa fétichisation alors que les transformations dans la manière de faire la guerre rendaient irréel son déploiement sur le champ de bataille.
L’intégration dans l’armée des brigades ORA des colonels Chomel et Bertrand, entre le Berry et les fronts de l’Atlantique, 1944-1945
Authors: Weiss Stéphane
Published: November 2022

L’Organisation de Résistance de l’Armée (ORA) joua un rôle de premier plan lors des combats de l’été 1944 contre les forces allemandes en retraite dans le Centre-Ouest de la France. Deux officiers se distinguèrent : les colonels Raymond Chomel et René Bertrand. L’historiographie tend à présenter leurs actions comme allant de pair. Ils connurent cependant des parcours clandestins distincts et appréhendèrent différemment la place de l’ORA parmi les Forces françaises de l’intérieur (FFI).Dès le mois de septembre 1944, les colonels Chomel et Bertrand ont cherché à transformer leurs groupements maquisards en amorces de grandes unités militaires. Cette transition, conduite entre le Berry et la façade atlantique, emprunta des voies distinctes de l’amalgame pratiqué concomitamment entre FFI et troupes nord-africaines au sein de la 1re armée française. En restituant la genèse des groupements des colonels Chomel et Bertrand, cet article met en lumière une perception du rôle de l’ORA qui ne fut pas monolithique. Il interroge également les relations entre l’état-major national de l’ORA et ses relais régionaux, qui ne se contentèrent pas d’attendre des directives supérieures au sein de l’environnement politique mouvant de l’automne 1944.
Cartes et fictions (XVIe-XVIIIe siècle)
Authors: Chartier Roger
Published: November 2022

Bilbo le Hobbit, les Chroniques de Narnia et Le Seigneur des anneaux ont habitué leurs lecteurs à rencontrer dans le livre une ou plusieurs cartes des territoires qu’ils décrivent. En allait-il de même pour les lecteurs des fictions de la première modernité, entre les XVIe et XVIIIe siècles ? L’introduction de cartes n’allait pas de soi. Leur impression augmentait le coût des ouvrages, et la capacité des mots à produire des images mentales les rendait inutiles. Néanmoins, les cartes apparurent dans les œuvres d’imagination.

Initiée avec les cartes des itinérances de don Quichotte et menant jusqu’aux éditions vénitiennes d’œuvres de L’Arioste et de Pétrarque, cette enquête s’est principalement attachée à deux généalogies. La première, anglaise, donne à voir les périples d’un voyageur imaginaire présenté comme bien réel : elle conduit des Voyages de Gulliver de Jonathan Swift à L’Utopie de Thomas More. La seconde, française et allégorique, a pour origine la Carte de Tendre, insérée dans la Clélie de Mademoiselle de Scudéry, et inclut les cartes galantes ou polémiques qui l’ont imitée. Selon les époques et les lieux, les cartes des fictions ont assumé divers rôles. Elles ont représenté des mondes à l’envers, satiriques, critiques ou utopiques ; elles ont brouillé la distinction entre le monde du livre et celui du lecteur ; elles ont nourri la raison et les rêves, au-delà même de la lettre du texte.

Cheminant d’œuvre en œuvre, Roger Chartier offre dans cet essai une nouvelle approche de la mobilité des fictions et de leurs interprétations.
Génie de la bande dessinée
Authors: Peeters Benoît
Published: November 2022

Oscillant entre la presse et le livre, l’enfance et l’âge adulte, la caricature et le réalisme, jouant des cases et des strips, du découpage et de la mise en page, des phylactères et des onomatopées, la bande dessinée est un langage à part entière que ni le cinéma, ni le jeu vidéo, ni Internet n’ont menacé jusqu’à présent. Si le neuvième art a déjà donné naissance à bien des chefs-d’œuvre, de Krazy Kat aux Aventures de Tintin, des Peanuts à Persepolis, des mangas au roman graphique, il est aujourd’hui plus divers et plus vivant que jamais. Dans cette conférence présentée le 7 octobre 2020 dans le cadre du cycle La bande dessinée au Collège de France, Benoît Peeters met en lumière les spécificités de ce médium parfois sous-estimé.

Depuis la fin du xviiie siècle, des surcotes avec des vagues de type tsunami ont pu être observées à trois reprises dans le vieux port de La Rochelle : le 6 septembre 1785, le 9 juin 1875 et le 22 avril 1882. Au regard de leur caractère très localisé et n’étant corrélées ni à des anomalies météorologiques de type tempête, ni à un séisme majeur, une recherche pluridisciplinaire a été engagée pour en déterminer l’origine. Nous réalisons dans un premier temps une analyse des connaissances actuelles à propos de la géologie, la sédimentologie, la sismicité et l’hydrologie de la zone d’étude. Ensuite, nous recoupons trois sources historiques qui nous fournissent des informations complémentaires à propos des événements : des données sismiques et météorologiques anciennes, des témoignages à propos des événements, et des cartes bathymétriques anciennes du pertuis d’Antioche. Grâce à des études comparées des bathymétries ante et post aléas, et la réalisation d’un modèle numérique des différences en bathymétrie, nous montrons des variations importantes dans le chenal situé entre l’île de Ré et La Pallice, une zone interprétée comme une cicatrice d’un glissement sous-marin. Cette déstabilisation de la pente sous-marine pourrait être à l’origine de vagues mesurées à La Rochelle en 1785, en 1875 et en 1882.

Tuning the PID (proportional-integral-derivative) controller is one of the most important tasks to achieve accurate control. Many methods have been developed to tune the values of P, I, and D; however, classical methods showed limitations. During the last decade, many works addressed the problem as an optimization problem and showed that nature-inspired optimization techniques are prevalent, such as genetic algorithms and particle swarm optimization. This chapter provides a brief overview of applying nature-inspired optimization techniques to PID control optimization.

In this chapter, design optimization is performed for a single-link flexible manipulator driven by a standard trapezoidal velocity input. The mass of the original manipulator is reduced by a quarter by design optimization without changing the payload. The finite element model, which is one of the non-rigid models, and topology optimization were utilized for the application. Dynamic stress and natural frequencies of the system are utilized as optimization objectives. The results were compared with the original manipulator in terms of both safety factor and vibration modes. In addition, the system parameters were compared with the tapered beam, and beam with reduced width, which was prepared to have the same mass as the optimized designs. As a result, although the mass of the original manipulator was reduced by one-fourth with the proposed design, it was observed that the dynamic stresses decreased. The study is expected to have significant implications in terms of improving the benefits of flexible robots and providing a contribution to the attenuation of vibrations and stresses.

Published: November 2022

The methodological basis for solving the problems of assessment, control, and formation of dynamic states of technical objects of transport and technological purposes in a state of vibration loading is being developed. Within the framework of structural mathematical modeling, mechanical oscillatory systems used as design schemes of technical objects are compared with schemes of dynamically equivalent automatic control systems. New results are presented in the field of technology for evaluating dynamic states and forms of interactions of elements of mechanical oscillatory systems with the reduced elastic characteristics. For mechanical oscillatory systems, an interpretation of dynamic states and forms of interactions in the form of an oriented graph has been developed, creating prerequisites for the classification of a set of dynamic states in which a system can be located under the condition of various types of force excitation

Published: November 2022

Multi-criteria optimization techniques have been applied to predict the best alternative solutions to meet the best results for all attributes. In the micro-machining processes, the various process parameters in the micro-machines, special experimental setup, tool profiles, workpiece materials, and working mediums are considered. Sometimes, the response attributes conflict with each other, making it difficult to estimate the best-influenced process parameters. The multi-criteria optimization methods are applied to solve the abovementioned conditions. In the chapter, the multi-criteria optimization technique: TOPSIS (technique for order of preference by similarity to ideal solution) implementation procedures, flowchart, and result interpretation have been demonstrated to optimize or predict the best micromachining process parameters. A case study on the application of the TOPSIS technique in electrical discharge machining (EDM)) has been illustrated.

Published: November 2022

History is proof of the thousands of wars which have taken place in all periods at different levels between nations. Thus, one learns that peace played an important role in ending these wars, or even preventing some of them. In fact, if you look at all religious scriptures and ceremonies, you will realize that all of them teach peace. They mostly advocate eliminating war and maintaining harmony. In other words, all of them hold out a sacred commitment to peace. It is after the thousands of destructive wars that humans realized the importance of peace. Earth needs peace in order to survive. This applies to every angle including wars, pollution, natural disasters, and more.

Authors: Kwok Gary , Tam Cai Lian
Published: November 2022

Depression is one of the leading mental health disorders that occurs frequently among university students. Self-esteem and lifestyle factors are modifiable factors that have the potential of preventing depression. The study aimed to explore the relationship for depression, self-esteem, and lifestyle factors among university students in Singapore and Malaysia, and whether individual lifestyle factors mediate the relationship. Participants completed an online questionnaire that consisted of socio-demographic, Beck Depression Inventory-ll. Rosenberg Self-Esteem Scale, and Simple Lifestyle Indicator Questionnaire. Data analyses showed that low self-esteem, diet, high smoking, and stress predicted an increase in the level of depression. Stress was a significant mediator for self-esteem and depression. Findings suggested that those with low self-esteem perceived stress as unmanageable, thereby increasing the level of depression scores.

Non‐small cell lung cancer (NSCLC) accounts for 75-80% of all lung cancer cases. Stage III NSCLC represents a highly heterogenous stage characterized by different disease presentations and a wide range of treatment options. For patients with good performance status and unresectable-stage III NSCLC with programmed death-ligands 1 (PD-L1) tumor proportion score (TPS) ≥1%, durvalumab consolidation immunotherapy after a platinum-based chemo-radiotherapy is strongly recommended. However, age, poor performance status, underlying comorbidities may represent contraindications for chemotherapy to be used in a subgroup of patients. Herein, we report a case of an 80-year-old male affected by a stage IIIB lung adenocarcinoma with overexpression of PD-L1 (TPS 90%) treated with pembrolizumab, an immune checkpoint inhibitor targeting PD-1/PD-L1 pathways, which shows a complete resolution of lung lesion after four cycles of treatment. Although randomized controlled trials are required, this case report may suggest the potential role of pembrolizumab for chemotherapy unsuitable patients with overexpressing PD-L1 unresectable-stage III NSCLC.

Improving the estimation of subtle blood-brain barrier permeability changes in aging using a deep learning approach
Authors: Bae Jonghyun , Ge Yulin , Kim Sungheon Gene
Published: November 2022

Background: Increasing evidence suggests detecting the subtle changes in blood-brain barrier (BBB) permeability in normal aging and in Alzheimer’s disease by using dynamic contrast-enhanced MRI (DCE-MRI) (Figure 1).1,2 However, measuring these subtle changes poses a great challenge for accurate measurement, resulting in inconsistent results among previous studies.1,2 Two major challenges are long scan times, as suggested by other studies, and the selection of the arterial input function (AIF). In this study, we aim to estimate the capillary level input function (CIF) using a deep learning network to overcome these two challenges.

Methods: Healthy volunteers (n=12, age 21-78) were recruited for DCE-MRI scan for 28 min. Golden-angle radial sampling parallel (GRASP) sequence was used to obtain the dynamic images at ~5s/frame. Individual AIF was sampled from the superior sagittal sinus of the brain. FSL3 was used to segment the gray and white matter. Each voxel was fitted using the graphical Patlak model4 to assess the vascular permeability-surface area product (PS) for both 28-min data and 10-min truncated data. We used a 3x3 kernel sliding through the images, and feed each voxel’s dynamic as the input to our vision-transformer.5 Training data were generated using individual AIFs with a mathematical model and used to simulate dynamic patches using the extended Patlak model.4

Results: The conventional approach with AIF results in the majority of voxels exhibiting negative PS, regardless of scan time. This is not physiologically valid, as this indicates the contrast agent extravasates into the vessel. However, the proposed approach with the network-predicted CIF results in most voxels in positive PS, even with a scan-time of 10 min. The estimated PS levels are in good accordance with the previous studies.1 Due to the limited sample size, we could not find the difference in BBB permeability between young and old groups.

Conclusions: Our approach showed promising quantification of subtle permeability. The results in this study suggest that our proposed CIF-based approach provides an appropriate input function for DCE analysis, allowing assessment of subtle permeability changes in the BBB even with a reduced scan time of 10 min. Future studies will include larger cohorts to investigate the BBB permeability changes in normal aging.
Cerebral blood flow dependency on systemic arterial circulation in progressive multiple sclerosis

Published: November 2022

Background: Cerebrovascular reactivity (CVR) is a regulatory mechanism responsible for redistributing cerebral blood flow based on vasoactive stimuli and fluctuations in metabolic demand. Under normal conditions and proper functioning of the neurovascular unit, a direct association between cerebral arterial blood flow and systemic arterial blood flow (SABF) is not expected. Previous studies have suggested impairment of CVR in multiple sclerosis (MS).1 Moreover, lower cerebral perfusion in MS has been linked with greater neuronal pathology and worse disability outcomes.2,3

Objectives: To determine the relationship between SABF and cerebral perfusion measures in MS patients.

Мaterials and methods: Cerebral perfusion and SABF were assessed in 118 patients (75 clinically isolated syndrome (CIS)/relapsing-remitting MS and 43 progressive MS) through magnetic resonance imaging (MRI) examination with dynamic susceptibility contrast perfusion-weighted imaging (DSC-PWI) and Doppler ultrasound, respectively. Measures of mean transit time (MTT) and time-to-peak (TTP), measured in seconds, of the normal-appearing whole brain (NAWB) and gray matter (GM) were calculated. Blood flow through the bilateral common carotid and vertebral arteries (in mL/min) represents the SABF. Whole brain volume (WBV) and body mass index (BMI) were used as additional covariates.

Results: Higher systolic blood pressure was associated with lower SABF (-0.256, p=0.006). In the total MS sample, higher SABF was associated with shorter MTT and TTP of the NAWB (r=-0.256, p=0.007 and r=-0.307, p=0.001) and GM (r=-0.239, p=0.012 and r=-0.3, p=0.001). The SABF and TTP associations were driven by the progressive multiple sclerosis (PMS) patients (r=-0.451, p=0.004 and r=-0.451, p=0.011). Only in PMS, SABF remained a significant predictor of NAWB (standardized β=-0.394, p=0.022) and GM TTP (standardized β=-0.351, p=0.037). MTT and TTP were significantly lower in patients within lower SABF quartiles when compared to the higher quartiles (age, sex, BMI and WBV-adjusted ANCOVA p<0.025). (Figure 1) The differences in PWI-based measured remained significant after additional correction for the prevalence of hypertension. Although statistically non-significant, PMS patients within the lower SABF quartiles had a numerically greater disability (expanded disability status scale scores of 5.9 vs 5.0 for Q1 and Q4), (multiple sclerosis severity score of 5.8 vs 3.8), slower walking as measured by timed 25-foot walk test (23.9 s vs 15.8 s) and worse hand dexterity as measured by 9-hole peg test (50.8 s vs. 29.3 s).

Conclusions: The direct relationship between systemic and cerebral blood flow seen in PMS patients may suggest a failure in cerebrovascular reactivity mechanisms and insufficient perfusion control. Cerebral blood flow in PMS may be increasingly dependent on the SABF.
