Published: July 2022

From various empirical evidences conducted in various parts of the world on the factors that influence dividend policy, the results show that there are similarities or mutual support between one study and another. However, there are also among the variables that have a relationship with dividend policy showing contradictory results between one study and another. This can happen due to differences in business characteristics, business environment, culture and legal regulations that differ from one country to another. From several studies in various parts of the world, the factors that have the most influence on dividend policy are profitability, firm size, firm age, liquidity, previous dividends, dividend payments, firm value and cash flow. and leverage have a negative relationship with dividend policy, and Firm size, firm risk and ownership structure do not have a direct influence on dividend payments in private banks in Bangladesh.

Leather is one of the essential materials in our life. It can be used widely to make different industrial products. Products made from leather are strong, expensive and durable which lasts for decades. So, It is very important for the industry to make a defect free product for their maximum profit and good customer feedback. Quality inspection is one of the important processes in the textile industry. It is done manually in most of the industry which is time taking, expensive, less accurate and requires lots of people. The main aim of our research work is to replace the manual process with automatic leather defect detection techniques which can save both time and money and increase the rate of production in the company. In this article, we proposed a deep learning-based semantic segmentation model that detects defects in leather images and highlights the defect with proper defect type. The experiments were carried out using the MVTEC leather dataset. The input images are changed into 256*256 pixels and then converted to gray-scale image and finally a semantic segmentation algorithm is applied to detect the leather defects. The experimental results are evaluated and compared using various semantic segmentation algorithms. We obtained the satisfactory result with evaluation metrics of 72.1% Intersection of Union (IOU) with 82.59% F1 Score on one of the semantic segmentation architectures Mobilenet_unet.

Fenomena alam yang berkaitan dengan maritim, seperti ribut, angin, ombak, taufan, bintang, air pasang, puting anak, gelombang dan arus, banyak ditemukan. Hal ini sangat berkait rapat dengan alam Melayu yang hebat dari aspek maritim. Sehubungan dengan itu, terdapat banyak bukti fenomena alam dalam pantun. Pantun bukan sekadar alat hiburan, gurauan, sindiran atau digunakan di majlis persandingan, tetapi mengandungi banyak falsafah dan akal budi. Kajian lepas tentang pantun Melayu banyak menyentuh aspek flora dan fauna yang terdapat dalam pantun. Makalah ini bertujuan untuk mengkategorikan fenomena alam yang berlaku di lautan dan mendeskripsikan makna pantun berdasarkan pendekatan semantik inkuisitif yang terdapat dalam bidang semantik. Bagi mencapai tujuan tersebut, kajian ini telah mengenal pasti 77 rangkap pantun yang terdapat dalam buku Kurik Kundi Merah Saga: Kumpulan Pantun Lisan Melayu yang mengandungi leksikal yang berkaitan dengan fenomena alam di lautan. Hasil kajian mendapati bahawa masyarakat Melayu terdahulu menganalogikan alam sekeliling (fenomena alam) dengan kehidupan manusia menerusi pantun. Fenomena alam ini dijadikan sebagai metafora dalam pantun menerusi pemerhatian dan pengalaman yang dilalui oleh masyarakat Melayu terdahulu. Pemilihan unsur fenomena alam ini adalah untuk mencungkil falsafah dan akal budi Melayu yang terselit dalam pantun menerusi kajian multidisiplin. Penghasilan pantun bukan sekadar sewenang-wenangnya, tetapi terselit falsafah dan akal budi Melayu di dalamnya.

Gottwaldovy pomníky ve Středočeském kraji
Authors: Šindelář Jan
Published: July 2022

This text explores the construction of monuments in Czechoslovakia in the 1970s and 1980s, detailing the history of all four monuments to the first Czechoslovak communist president Klement Gottwald in the Central Bohemian Region. Based on archival research, this paper attempts to unveil the practices of post-1968 memory policy at regional level. In four main sections, the text traces, in succession, the construction of ideologically motivated works in the towns of Příbram, Pečky, Rakovník and Nymburk, bringing the decision-making processes of the communist party and state authorities at local and national level under scrutiny.

Cumbersome bureaucracy combined with chronic supply difficulties and the excessive workload of approved artists caused several years of delays to projects endorsed by the regime. Owing to their close ties to the communist regime, all four sculptures were removed from public display shortly after November 1989, i.e. after the fall of communism, but they were not destroyed. Their different fates − from being a gallery exhibit to ending up in a technical services warehouse − open up questions about the meaningful use of similar artefacts.
Creativity of female artists in Italian fine arts of XV–XVII centuries
Authors: Stakhevych Halyna , Kokhan Natalia
Published: July 2022

The article provides an overview and reveals the features of the professional formation, development and social status of female artists’ creativity in the Italian fine arts of the XVI-XVII centuries. The value of their artistic heritage for future generations has been established. It was stated that the role of a female artist in society was influenced by both social and gender factors, in particular, the fact that the profession of a master artist was assigned to men, and the teaching of art to girls was related to obligatory household chores or hobbies. It has been proven that already in the XV century, artists appeared in Italy whose activities went beyond these boundaries. Initially, they were self-taught nuns, such as Catherine of Bologna, but by the end of the century, the work of female artists acquired a professional character (for example, Pr. de’Rossi). It is noted that, since that time, works of art by female artists have influenced the change in social stereotypes about their work. It was found that Italian female artists of the Renaissance and subsequent centuries turned mainly to the genres of portrait, landscape and still life. However, there are cases of creation of monumental works (Pl. Nelli) or reflections of dramatic events (A. Gentileschi). It was revealed that by the beginning of the XVIII century in these genres, female artists were in full competition with men and were the inventors of both new genres (S. Anguissola) and new painting techniques (R. Carriera). There is also a manifestation of their author’s vision in compositions on religious themes, on historical and mythological themes. It has been proven that the achievements of Italian female artists of the XV–XVII centuries were no less significant than those of male artists.
Functional role of the cello in Handel's solo cantatas
Authors: Grechanivska Tetyana
Published: July 2022

The article considers the functional role of the cello in the vocal-instrumental musical works of the Baroque period and attempts to shift the problem from the practical-performing background into the field of professional musicological discourse. Two Italian solo cantatas by G. F. Handel were chosen for analysis, in which the composer clearly structured and used instrumental accompaniment according to the stylistic norms of the instrumental and vocal ensemble of the 17th–18th centuries — as a dialogue of two voices accompanied by others. Emphasis is placed on the differences between the basso continuo and obliggato parts, which reveal the main directions of the functional purpose of the instrument and prove the importance of the cello in the ensemble performance of the Baroque period.
It is revealed that the problem of manifestation of performing individuality and interpretation of Baroque works in the concert practice of today is the subject of a separate musicological study and requires more detailed research. In this discourse, Baroque musical literature is a vast field for research, rightly playing a dominant role in contemporary performing arts.
Modern algorithms for interpreting the history of music: an epistemological discourse
Authors: Zavіalova Olha , Yarko Mariya
Published: July 2022

In the article a historically significant situation is considered, when with the revival in the last third of the twentieth century of B. Asafyev's ideas on music as a sound intonation environment and an art of intoned meaning, as well as because of the expansion of modern humanitarian knowledge due to close interdisciplinary links, the musical criticism underwent a process of active development, synthesizing the subject field of historical and theoretical musicology on the basis of culturology and philosophy. The achievements of this process have been analyzed, which demonstrate a radical renovation of the conceptual and semantic content of the leading categories of musicology, in particular, in relation to the interpretation of historical phenomena in music in view only of their inherent worldview paradigms. Analytical algorithms for detecting epistemologically reliable data on the style of epochs and criteria for compiling their generalized "image" under the guise of an invariant model are specified. The expediency of a monadological (nonlinear) approach to the history of music, which methodologically corresponds to the idea of "philosophy of integrity", is proposed and substantiated.

Ethics of Political Communication in Welcoming the Implementation of the 2024 General Election
Authors: Malik Dedy Djamaluddin
Published: July 2022

The ethics of political communication has an essential function and determines the democratization system in Indonesia, besides that there is a battle of interests to influence, seize, maintain, and expand power carried out by political communicators, namely the elite (rulers) and the public. Meanwhile, in interpreting democratic involvement in the political system, it explains aspects from adherence to democratic norms and values to behaviors designed to affect the quality of life of the community at large. This research is a type of qualitative research, using a descriptive method, while the purpose of this study is to determine the extent of the role of political communication ethics in welcoming the 2024 general election in Indonesia. Politics as a process of controlling and coordinating all elements within the scope of government must always synergize with various interests of the wider community. In certain situations, political communication emphasizes the decision-making process rather than thinking about the impact of the decisions or policies made. This process is a mechanism to achieve a series of goals, especially in accommodating symbols of public interest and symbols of power. Political communication as a complex communication activity, involves many factors and components in it ranging from language, symbols, leading actors, media, society, and various public policies.
Probing Dynamics and Thermal Properties Inside Molecular Tori with CO Rovibrational Absorption Lines
Authors: Matsumoto Kosei , Nakagawa Takao , Wada Keiichi , Baba Shunsuke , Onishi Shusuke , Uzuo Taisei , Isobe Naoki , Kudoh Yuki
Published: July 2022

A recent hydrodynamic model, the radiation-driven fountain model (Wada et al. 2016), presented a dynamical picture that active galactic nuclei (AGNs) tori sustain their geometrical thickness by gas circulation around AGNs, and previous papers have confirmed that this picture is consistent with multiwavelength observations of nearby Seyfert galaxies. Recent near-infrared observations implied that CO rovibrational absorption lines (ΔJ = ± 1, v = 0 − 1, λ ∼ 4.7 μm) could probe the physical properties of the inside tori. However, the origin of the CO absorption lines has been under debate. In this paper, we investigate the origin of the absorption lines and conditions for detecting them by performing line radiative transfer calculations based on the radiation-driven fountain model. We find that CO rovibrational absorption lines are detected at inclination angles θ
obs = 50°–80°. At the inclination angle θ
obs = 77°, we observe multi-velocity components: inflow (v
LOS = 30 km s−1), systemic (v
LOS = 0 km s−1), and outflows (v
LOS = −75, − 95, and −105 km s−1). The inflow and outflow components (v
LOS = 30 and −95 km s−1) are collisionally excited at the excitation temperatures of 186 and 380 K up to J = 12 and 4, respectively. The inflow and outflow components originate from the accreting gas on the equatorial plane at 1.5 pc from the AGN center and the outflowing gas driven by AGN radiation pressure at 1.0 pc, respectively. These results suggest that CO rovibrational absorption lines can provide us with the velocities and kinetic temperatures of the inflow and outflow in the inner few parsec region of AGN tori, and the observations can probe the gas circulation inside the tori.
New Constraints on Cosmic Particle Populations at the Galactic Center Using X-Ray Observations of the Molecular Cloud Sagittarius B2
Authors: Rogers Field , Zhang Shuo , Perez Kerstin , Clavel Maïca , Taylor Afura
Published: July 2022

The Sagittarius B2 (Sgr B2) molecular cloud complex is an X-ray reflection nebula whose nonthermal X-ray emissions have continued to decrease since 2001 as it reprocesses one or more past energetic outbursts from the supermassive black hole Sagittarius A* at the Galactic Center. The X-ray reflection model explains the observed time variability of Sgr B2 and provides a window into the luminous evolutionary history of our nearest supermassive black hole. In light of evidence of elevated cosmic particle populations in the Galactic Center, X-rays from Sgr B2 are also of interest as a probe of low-energy (sub-GeV) cosmic rays, which may be responsible for an increasing relative fraction of the nonthermal emission as the contribution from X-ray reflection decreases. Here, we present the most recent NuSTAR and XMM-Newton observations of Sgr B2, from 2018, and we emphasize the Kα fluorescence line of neutral Fe. These 2018 observations reveal small-scale variations within lower-density portions of the complex, including brightening features, yet still enable upper limits on X-rays from low-energy cosmic-ray interactions in Sgr B2. We present Fe Kα line fluxes from cloud regions of different densities, facilitating comparison with models of ambient low-energy cosmic-ray interactions throughout the cloud.
Doppler-velocity Drifts Detected in a Solar Prominence
Authors: Zapiór Maciej , Heinzel Petr , Khomenko Elena
Published: July 2022

We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at the Ondřejov Observatory. Dopplergrams and integrated intensity maps of the whole prominence were obtained from observations in six spectral lines: Ca ii H, Hϵ, Hβ, He i D3, Hα, and Ca ii IR. By combining integrated intensity maps with non-LTE radiative-transfer modeling, we carefully identified areas in an optically thin regime. The comparison of the Doppler-velocity maps and scatterplots from different lines shows the existence of differences in the velocity of ions and neutrals called velocity drift. The drift is of a local nature, present mostly at prominence edges in the area with a large velocity gradient, as can be tentatively expected based on multifluid MHD models. We could not explore the time evolution of the drift, since our data set consists of a single scan only. Our paper brings another contribution to a rather controversial problem of the detection of multifluid effects in solar prominences.
Measuring Star Formation and Black Hole Accretion Rates in Tandem Using Mid-infrared Spectra of Local Infrared Luminous Galaxies
Authors: Stone Meredith , Pope Alexandra , McKinney Jed , Armus Lee , Díaz-Santos Tanio , Inami Hanae , Kirkpatrick Allison , Stierwalt Sabrina
Published: July 2022

We present the results of a stacking analysis performed on Spitzer/Infrared Spectrograph high-resolution mid-infrared (mid-IR) spectra of luminous infrared galaxies (LIRGs) in the Great Observatories All-Sky LIRG Survey. By binning in relation to mid-IR active galactic nucleus (AGN) fraction and stacking spectra, we detect bright emission lines [Ne ii] and [Ne iii], which trace star formation, and fainter emission lines [Ne v] and [O iv], which trace AGN activity, throughout the sample. We find that the [Ne ii] luminosity is fairly constant across all AGN fraction bins, while the [O iv] and [Ne v] luminosities increase by over an order of magnitude. Our measured average line ratios, [Ne v]/[Ne ii] and [O iv]/[Ne ii], at low AGN fraction are similar to H II galaxies, while the line ratios at high AGN fraction are similar to LINERs and Seyferts. We decompose the [O iv] luminosity into star formation and AGN components by fitting the [O iv] luminosity as a function of the [Ne ii] luminosity and the mid-IR AGN fraction. The [O iv] luminosity in LIRGs is dominated by star formation for mid-IR AGN fractions ≲0.3. With the corrected [O iv] luminosity, we calculate black hole accretion rates (BHARs) ranging from 10−5
M
⊙ yr−1 at low AGN fractions to 0.2 M
⊙ yr−1 at the highest AGN fractions. We find that using the [O iv] luminosity, without correcting for star formation, can lead to overestimation of the BHAR by up to a factor of 30 in starburst-dominated LIRGs. Finally, we show that the BHAR/star formation rate ratio increases by more than three orders of magnitude as a function of mid-IR AGN fraction in LIRGs.
Effect of the Modified Gravity on the Large-scale Structure Formation
Authors: Kumar Sharma Ajay , Manohar Verma Murli
Published: July 2022

We investigate the formation of the large-scale structures in the present accelerated era in the f(R) gravity background. This is done by considering the linear growth of matter perturbations at low redshift z < 1. The effect of f(R) alters the behavior of the matter density perturbations from the matter-dominated universe to the late-time accelerated universe, which is encoded in the Newtonian gravitational constant as G → G
eff. The modified gravitational constant (G
eff) depends on the form of f(R). The late-time accelerated expansion affects the formation of large-scale structures by slowing down the growth of matter density. On the other hand, f(R) increases the growth rate of the matter density perturbations. We have found that the source term in the f(R) background, G
effΩ
m
, overcomes the accelerated expansion and the effect of accelerated expansion suppresses the formation of the large-scale structures in the asymptotic future.
An Extension of Gmunu: General-relativistic Resistive Magnetohydrodynamics Based on Staggered-meshed Constrained Transport with Elliptic Cleaning
Authors: Cheong 張 Patrick Chi-Kit 志杰 , Tung Pong David Yat , Long Yip Anson Ka , Feng Li Tjonnie Guang
Published: July 2022

We present the implementation of general-relativistic resistive magnetohydrodynamics solvers and three divergence-free handling approaches adopted in the General-relativistic multigrid numerical (Gmunu) code. In particular, implicit–explicit Runge–Kutta schemes are used to deal with the stiff terms in the evolution equations for small resistivity. The three divergence-free handling methods are (i) hyperbolic divergence cleaning (also known as the generalized Lagrange multiplier), (ii) staggered-meshed constrained transport schemes, and (iii) elliptic cleaning through a multigrid solver, which is applicable in both cell-centered and face-centered (stagger grid) magnetic fields. The implementation has been tested with a number of numerical benchmarks from special-relativistic to general-relativistic cases. We demonstrate that our code can robustly recover from the ideal magnetohydrodynamics limit to a highly resistive limit. We also illustrate the applications in modeling magnetized neutron stars, and compare how different divergence-free handling methods affect the evolution of the stars. Furthermore, we show that the preservation of the divergence-free condition of the magnetic field when using staggered-meshed constrained transport schemes can be significantly improved by applying elliptic cleaning.
A review of Leuctridae (Insecta, Plecoptera) in Wuyi Mountains, China
Authors: Yang Yu-Ben , Zhu Bin-Qing , Rehman Abdur , Du Yu-Zhou
Published: July 2022

Wuyi Mountains are located in the northern Oriental Region and the edge of the southern Palaearctic Region. They have a unique geographical location, complex landform and superior climatic conditions, providing a good ecological environment for Leuctridae species. However, due to the damage of some holotypes in the 20th century, limited drawings and lack of colour figures, it is necessary to reorganise and supplement the preserved Leuctridae specimens from Wuyi Mountains.

In this study, we found that there are twelve species of Leuctridae recorded in Wuyi Mountains, accounting for about 20% of the recorded species of Leuctridae in China. These records include two genera and five new distribution records species: one species of the genus Paraleuctra Hanson, 1941: Paraleuctra orientalis (Chu 1928) and eleven species of the genus Rhopalopsole Klapálek, 1912, including five new distribution records to Wuyi Mountains: Rhopalopsole fengyangshanensis Yang, Shi & Li, 2009; Rhopalopsole sinensis Yang & Yang, 1993; Rhopalopsole yangdingi Sivec & Harper, 2008; Rhopalopsole flata Yang & Yang, 1995; Rhopalopsole basinigra Yang & Yang, 1995. Now a total of twelve species of Leuctridae have been recorded from Wuyi Mountains, Fujian Province of south-eastern China. In this paper, we also provide a key to the male, new images and some notes of these twelve species, except Rhopalopsole recurvispina (Wu, 1949) and Rhopalopsole spiniplatta (Wu, 1949). We failed to collect these two species and we regard R. recurvispina as a nomen dubium, because there are no distinctive features that can be used to distinguish this species.

A new association of relict maquis with Ptilostemon greuteri (Oleo-Ceratonion, Quercetea ilicis), located in a circumscribed area of north-western Sicily
Authors: Gianguzzi Lorenzo , Caldarella Orazio , Pasta Salvatore
Published: July 2022

This paper illustrates the results of a survey aimed at deepening available knowledge on the ecology of Ptilostemon greuteri (Asteraceae), a very rare palaeoendemic and relict nano-phanerophyte discovered about 15 years ago on Monte Inici, near Castellammare del Golfo (province of Trapani, north-western Sicily). Two plant communities characterised by P. greuteri are described in detail; they occur in the locus classicus and in a second, recently discovered stand, which is also very localised and threatened by fire. The field investigations revealed that the sites where the species grows are very similar from the ecological point of view; in fact, both of them are located on the steep slopes of deep gullies, benefitting from constantly cool and shady microclimatic conditions, and allowed to a) better identify the currently preferred habitat (ledges, screes at the base of cliffs), b) analyse from a floristic and phytosociological point of view the maquis communities where P. greuteri grows as co-dominant or dominant species, referable to the class Quercetea ilicis, c) to identify the syndynamic role that these coenoses play within the series and microgeoseries of local vegetation. As far as syntaxonomy is concerned, the Malvo olbiae-Ptilostemonetum greuteri ass. nova is described, a basiphilous, thermophilous and shade-tolerant maquis framed in the Oleo-Ceratonion alliance. Moreover, two subassociations are described: 1) typicum subass. nova, corresponding to a pioneer maquis community prevailing on the coarse, loose and mobile debris located along the slopes at the base of rock cliffs, where P. greuteri is clearly dominant and shows a nano-phanerophytic habitus, and 2) euphorbietosum bivonae subass. nova, a primary aspect found of the ledges of carbonate cliffs, where the species can play either a dominant or co-dominant role with other elements of the maquis (Euphorbia bivonae, Chamaerops humilis, etc.), sometimes showing a slightly smaller size.

Le numérique pour l’accès à l’emploi : parole à une collectivité
Authors: Labich Siham , Bressan Fabien
Published: July 2022

L’emploi, notamment des jeunes, est un sujet majeur dans les quartiers prioritaires, dont les habitant.e.s souffrent plus qu’ailleurs du chômage. Pour autant, la politique de la ville, alliée à d’autres dispositifs de droit commun portés par Pôle emploi et les missions locales, est un formidable outil pour lutter contre ce problème pour peu que les acteurs locaux le décident. En misant sur les opportunités offertes par les outils numériques, c’est ce qu’a choisi de faire la Ville de Saint-Étienne, comme nous l’explique Siham Labich, adjointe chargée de la politique de la ville, de l’éducation populaire, de la laïcité et des relations avec les cultes.
Les métiers du web sont-ils vraiment une opportunité pour les jeunes des quartiers prioritaires ?
Authors: Bruyas Dorie
Published: July 2022

Faut-il encore croire que les métiers du web – sans prérequis – sont une opportunité pour les jeunes des quartiers prioritaires ? Telle est la question à laquelle Dorie Bruyas, directrice de Fréquence écoles, membre fondatrice de LDigital et d’Hinaura, tente de répondre. Même si les données manquent pour objectiver la situation, les indices repérés font semer le doute sur l’efficacité de la stratégie massive de déploiement de certains métiers du web.
La filière du reconditionnement informatique et numérique : un gisement d’emplois pour les territoires
Authors: Baysang-Michelin Victor , Jobin Gabriel
Published: July 2022

Le réemploi des équipements informatiques et numériques s’inscrit dans un cercle vertueux dans lequel collectivités locales, entreprises, associations, usagers… collaborent pour construire un nouveau modèle économique qui préserve les ressources naturelles et participe à l’insertion sociale et professionnelle des publics éloignés de l’emploi. C’est ce dont témoignent Victor Baysang-Michelin, responsable régional d’Emmaüs Connect, à travers le dispositif LaCollecte.tech, et Gabriel Jobin, directeur général de TRI-Rhône-Alpes, via les actions de formation au numérique que la coopérative propose.

Le numérique au service de l’inclusion professionnelle : des propositions pour l’avenir
Authors: Dufour Mathias , Rabier Romain , Stride Claire
Published: July 2022

Le numérique a des effets ambivalents sur les territoires. D’un côté les innovations de produits et de services sont porteuses de désenclavement, de croissance économique et de développement (durable) des territoires. De l’autre le numérique est source d’aggravation des inégalités économiques, sociales et territoriales. Comment faire pour mettre le numérique au service de l’inclusion professionnelle dans tous les territoires 1 , et en particulier ceux dits « fragilisés » comme les quartiers prioritaires de la politique de la ville ? Mathias Dufour, Romain Rabier et Claire Stride, du think tank #Leplus important, nous présentent des solutions concrètes pour relever les défis sociaux de l’économie numérique.
La Méditerranée et la guerre en Ukraine : la rupture est aussi au sud
Authors: Ausseur Pascal
Published: July 2022

La guerre déclenchée par la Russie contre l’Ukraine bouleverse les équilibres géopolitiques déjà fragiles autour de la Méditerranée. Les tensions se sont accrues, attisées par une posture russe agressive pour déstabiliser l’Europe, ses institutions et ses projets politiques et économiques. Il est urgent de réagir et de sortir de l’irénisme.
Un monde, deux théâtres : dilemmes et ricochets entre Europe et Indopacifique
Authors: Haroche Pierre
Published: July 2022

Si l’Indopacifique peut sembler éloignée des préoccupations des Européens, il faut souligner le dilemme stratégique imposé désormais à l’Europe. Celle-ci y a des intérêts et ne peut se désintéresser de la compétition entre les États-Unis et la Chine. Cela signifie augmenter la présence européenne dans cette région.

Authors: Schultheiss Christian
Published: July 2022

La mer de Chine méridionale (MCM) fait l’objet d’intenses convoitises et de revendications notamment par la Chine. Celle-ci pratique une guerre juridique autour du lawfare pour justifier ses actions. Cependant, les résultats semblent mitigés au regard du manque de soutien international.
L’ AUKUS , une surprise stratégique pour la France ?
Authors: Zajec Olivier
Published: July 2022

L’annonce de l’alliance AUKUS a été présentée en France comme une surprise stratégique – sans oublier l’aspect humiliant – mais la question n’est-elle pas plutôt la révélation de la surestimation de la puissance française. Celle-ci doit désormais se réinventer dans la zone indopacifique pour redevenir crédible.
L’avenir du statu quo et de la paix dans le détroit de Taïwan
Authors: Duchâtel Mathieu
Published: July 2022

Taïwan et son détroit focalisent les divergences stratégiques entre la Chine et l’île indépendantiste soutenue par les États-Unis. Ceux-ci disposent de Sous-marins nucléaires d’attaque qui assurent une mission dissuasive face à la marine chinoise. D’où le choix de l’Australie de se doter de SNA dans le cadre de l’alliance AUKUS .

AUKUS et la technologie dronique en Indopacifique
Authors: Zubeldia Océane
Published: July 2022

L’Indopacifique se caractérise par ses élongations et donc des zones difficiles à surveiller. La course à l’armement est une réalité avec un emploi de plus en plus large des drones aériens et maritimes qui constituent des démultiplicateurs d’effet. Cela risque d’accroître les tensions en l’absence de réelle coopération internationale.
L’implacabilité en analyse
Authors: Winborn Mark , Raguet Christian
Published: July 2022

Cet article examine la question de l’implacabilité en analyse, une attitude de l’analyste qui se traduit dans ses agissements, tels que la confrontation par l’interprétation, en particulier celle des défenses du patient. Il me semble que les influences exercées sur la culture thérapeutique ont entraîné un mouvement d’éloignement de l’implacabilité comme partie prenante de l’attitude analytique. L’article identifie, dans la littérature analytique, des parallèles conceptuels ainsi que des thèmes archétypaux d’implacabilité associés à une possible évolution psychique. Il évoque l’ambivalence de l’analyste par rapport à l’implacabilité, ainsi que la relation entre implacabilité et autorité analytique. Enfin, il étudie les facteurs curatifs sous-tendant l’implacabilité analytique.
Optimizing Use of Vagus Nerve Stimulation for the Psychiatric Patient
Authors: Goldwaser Eric L. , Aaronson Scott T.
Published: July 2022

Psychiatric management for difficult-to-treat, also known as ‘treatment-resistant’, mood disorders is limited. Depression that is chronic and persistent in spite of adequate dose and duration of standard psychopharmacologic strategies remains a highly impactful yet understudied area. With the advent of neuromodulatory interventions, like vagus nerve stimulation (VNS), symptom improvements may be less elusive than previously thought. However, due to a host of limitations on the part of provider knowledge, insurance coverages, or identification of properly indicated patient populations, VNS is widely underutilized despite its efficacy and benefit. In this review, we detail a variety of considerations surrounding the use of VNS, as well as practical information for the part of the clinician. VNS represents a burgeoning treatment option and continues to hold promise in some of psychiatry's most marginalized patients.

Zavadskij modules over cluster-tilted algebras of type $ \mathbb{A} $
Authors: Cañadas Agustín Moreno , Serna Robinson-Julian , Gaviria Isaías David Marín
Published: July 2022

Zavadskij modules are uniserial tame modules. They arose from interactions between the poset representation theory and the classification of general orders. The main problem is to characterize Zavadskij modules over a finite-dimensional algebra $ A $. In this setting, we prove that the indecomposable uniserial $ A $-modules with a mast of multiplicity one in each vertex are Zavadskij modules. Since the Zavadskij property carries over to direct summands, but it is not invariant under the formation of direct sums, we give a criterion to determine when the direct sum of indecomposable Zavadskij modules is again a Zavadskij module. In addition, we use the triangulations of the $ n+3 $-gon associated with the cluster-tilted algebra of type $ \mathbb{A}_{n} $ to give a formula for the number of indecomposable Zavadskij modules over any cluster-tilted algebra of type $ \mathbb{A}_{n} $. In this case, the formula gives the dimension of the cluster-tilted algebra. As an application, we discuss some integer sequences in the OEIS (The On-Line Encyclopedia of Integer Sequences) that allow us to enumerate indecomposable Zavadskij modules.
Developing a leap-frog meshless methods with radial basis functions for modeling of electromagnetic concentrator
Authors: He Bin
Published: July 2022

The main goal of this paper is to develop a fast and effective meshless method by using radial basis function (RBF) for the time domain model equations of electromagnetic wave concentration device. This is mainly because the complex model equations involve different partial differential equations in different subdomains, which makes the meshless method very attractive and also very challenging. In order to simulate the propagation of electromagnetic waves in the electromagnetic concentrator, perfect matching layer technology was used to reduce an unbounded domain problem into a bounded domain problem. Borrowing the idea of the leap-frog finite-difference time-domain scheme, I develop the leap-frog RBF meshless method to solve the coupled complex modeling equations. The numerical results obtained by using a multiquadric RBF and Gaussian RBF demonstrate that our RBF method is very effective.
