Authors: Atiyah Oqbah , Thalij Saadi
Published: April 2022

COVID-19 emerged in 2019 in china, the worldwide spread rapidly, and caused many injuries and deaths among humans. Accurate and early detection of COVID-19 can ensure the long-term survival of patients and help prohibit the spread of the epidemic. COVID-19 case classification techniques help health organizations quickly identify and treat severe cases. Algorithms of classification are one the essential matters for forecasting and making decisions to assist the diagnosis, early identification of COVID-19, and specify cases that require to intensive care unit to deliver the treatment at appropriate timing. This paper is intended to compare algorithms of classification of machine learning to diagnose COVID-19 cases and measure their performance with many metrics, and measure mislabeling (false-positive and false-negative) to specify the best algorithms for speed and accuracy diagnosis. In this paper, we focus onto classify the cases of COVID-19 using the algorithms of machine learning. we load the dataset and perform dataset preparation, pre-processing, analysis of data, selection of features, split of data, and use of classification algorithm. In the first using four classification algorithms, (Stochastic Gradient Descent, Logistic Regression, Random Forest, Naive Bayes), the outcome of algorithms accuracy respectively was 99.61%, 94.82% ,98.37%,96.57%, and the result of execution time for algorithms respectively were 0.01s, 0.7s, 0.20s, 0.04. The Stochastic Gradient Descent of mislabeling was better. Second, using four classification algorithms, (eXtreme-Gradient Boosting, Decision Tree, Support Vector Machines, K_Nearest Neighbors), the outcome of algorithms accuracy was 98.37%, 99%, 97%, 88.4%, and the result of execution time for algorithms respectively were 0.18s, 0.02s, 0.3s, 0.01s. The Decision Tree of mislabeling was better. Using machine learning helps improve allocate medical resources to maximize their utilization. Classification algorithm of clinical data for confirmed COVID-19 cases can help predict a patient’s need to advance to the ICU or not need by using a global dataset of COVID-19 cases due to its accuracy and quality.

Evaluating the efficacy and safety of TS1-Cisplatin regimen in the first-line treatment of advanced gastric cancer patients
Authors: Trinh Le Huy
Published: April 2022

Objectives: To evaluate the efficacy and safety of TS1-Cisplatin regimen in the first-line treatment of metastatic gastric cancer patients.

Methods: 38 eligible patients were treated with TS1-cisplatin at Hanoi Medical University Hospital from January 2018 to December 2021.

Results: Mean age was 57.4. Male: female ratio = 3.2:1. Most patients had good performance status (PS 0 or PS 1 – 84.2%). Most received dose rate from 85% to 100% of standard dose (78.9%). After six cycles, complete response rate was 13.2%, partial response rate was 42.1%. The median progression-free survival was 5.7 months. The median overall survival was 13.5 months. Neutropenia was the most common adverse event (52.6%), of which 13.1% was in grade 3-4. Diarrhea accounted for 36.8%, only one of which was in grade 3 (2.6%). Only one patient had hand-foot syndrome (2.6%).

Conclusion: TS1–Cisplatin regimen in metastatic gastric cancer had a good response rate while being safe and tolerable.
Lifestyle as a Predictor of Socio-Economic Status in Retirement
Authors: Fabian Mwosi , Charles Edaku , Robina Mirembe , Eton Marus
Published: April 2022

Most studies on retirement planning focus on preserving money and accumulating wealth and ignore the lifestyles of individual employees. This study promotes a discussion on lifestyle as a predictor of socio-economic status in retirement. Based on 236 pensioners from the Busoga sub-region, we used ‘the way of living’ to indicate lifestyle. We used household expenditure, access to healthcare, and housing quality to indicate socio-economic status. We used descriptive measures to report on lifestyle and Spearman’s correlation coefficient to document the relationship between workers’ lifestyle and socio-economic status in retirement. Strong attachments to family and intimate relations during one’s working life predict a satisfying retirement life. Civil servants who avoid harmful substances and exercise regularly are likely to retire in good health. There is a moderate and significant association between lifestyle and socio-economic status among civil servants in Uganda. Supervisors and human resource officers in government agencies and departments should conduct regular workshops to help government workers build strong attachments to their families, friends, social groups, and communities. We provide a solid foundation for working individuals to always reflect on the quality of their relations with their families, friends, social groups, and communities. This study contributes to the retirement planning research by shifting the focus to lifestyle, arguing that all forms of saving and financial planning for the future hinge on an individual worker’s lifestyle.
The ESO-VLT MIKiS Survey Reloaded: Velocity Dispersion Profile and Rotation Curve of NGC 1904*

Published: April 2022

We present an investigation of the internal kinematic properties of M79 (NGC 1904). Our study is based on radial velocity measurements obtained from the ESO-VLT Multi-Instrument Kinematic Survey (MIKiS) of Galactic globular clusters for more than 1700 individual stars distributed between ∼0.″3 and 770″ (∼14 three-dimensional half-mass radii) from the center. Our analysis reveals the presence of ordered line-of-sight rotation with a rotation axis almost aligned along the east–west direction and a velocity peak of 1.5 km s−1 at ∼70″ from the rotation axis. The velocity dispersion profile is well described by the same King model that best fits the projected density distribution, with a constant central plateau at σ
0 ∼ 6 km s−1. To investigate the cluster rotation in the plane of the sky, we have analyzed the proper motions provided by the Gaia EDR3, finding a signature of rotation with a maximum amplitude of ∼2.0 km s−1 at ∼80″ from the cluster center. Analyzing the three-dimensional velocity distribution for a subsample of 130 stars, we confirm the presence of systemic rotation and find a rotation axis inclination angle of 37° with respect to the line of sight. As a final result, the comparison of the observed rotation curves with the results of a representative N-body simulation of a rotating star cluster shows that the present-day kinematic properties of NGC 1904 are consistent with those of a dynamically old system that has lost a significant fraction of its initial angular momentum.
Assessing the Impact of Hydrogen Absorption on the Characteristics of the Galactic Center Excess
Authors: Pohl Martin , Macias Oscar , Coleman Phaedra , Gordon Chris
Published: April 2022

We present a new reconstruction of the distribution of atomic hydrogen in the inner Galaxy that is based on explicit radiation transport modeling of line and continuum emission and a gas-flow model in the barred Galaxy that provides distance resolution for lines of sight toward the Galactic center. The main benefits of the new gas model are (a) the ability to reproduce the negative line signals seen with the HI4PI survey and (b) the accounting for gas that primarily manifests itself through absorption. We apply the new model of Galactic atomic hydrogen to an analysis of the diffuse gamma-ray emission from the inner Galaxy, for which an excess at a few GeV was reported that may be related to dark matter. We find with high significance an improved fit to the diffuse gamma-ray emission observed with the Fermi-LAT, if our new H i model is used to estimate the cosmic-ray induced diffuse gamma-ray emission. The fit still requires a nuclear bulge at high significance. Once this is included there is no evidence of a dark-matter signal, be it cuspy or cored. But an additional so-called boxy bulge is still favored by the data. This finding is robust under the variation of various parameters, for example, the excitation temperature of atomic hydrogen, and a number of tests for systematic issues.
Rêves de patients et contre-transfert
Authors: Blechner Mark J. , Frey Nicole
Published: April 2022

Les rêves exposés en psychanalyse peuvent être à l’image du transfert du patient mais aussi à celle du contre-transfert, de la contre-résistance, et contre-anxiété du psychanalyste. L’analyste peut utiliser les rêves des patients comme supervision du fait de la capacité de communiquer propre au rêve. Des signes objectifs peuvent indiquer une interférence contre-transférentielle de l’interprétation du rêve par l’analyste. Par la technique de réciprocité, d’interprétation interactive, le sens du rêve à propos du processus transféro-contre-transférentiel peut être éclairci. Habituellement dans le travail à propos d’un rêve, il y a un stade intermédiaire durant lequel le sens du rêve est adopté dans le travail d’interprétation. Les exemples cliniques comprennent « Le beau rêve », repris par Freud, avec des exemples extraits de l’ouvrage clinique de Gill et Hoffman (1982) et de la pratique de l’auteur.
La mémoire adhésive
Authors: Athanassiou-Popesco Cléopâtre
Published: April 2022

Cet article tente de faire un lien entre la forme prise par la mémoire et l’espace psychique dans lequel cette mémoire se constitue. En l’occurrence, une différenciation se doit d’être faite entre une mémoire dont la permanence se fonde sur des processus introjectifs dans un monde en trois dimensions et une mémoire dite « adhésive », dont la permanence ne se fonde que sur une inscription en surface. Cette étude associe la trace mnésique bidimensionnelle à la pratique du tatouage, comme l’illustre une présentation clinique mettant en évidence les éléments traumatiques vécus par une patiente et ses répercussions non seulement dans la constitution de son identité mais en partie également dans la forme prise par sa mémoire.
Césures primordiales et transplantations adoptives
Authors: Guasto Gianni , Lucini Rudi , Guasto Gianni
Published: April 2022

Les césures primordiales qui se produisent chez des enfants ayant subi des traumas ou des abandons précoces, et adoptés, par la suite, par des parents « suffisamment bons », donnent lieu à la persistance de « mauvais objets introjectés » qui se manifestent lors de la crise d’adolescence. Ils témoignent du fait que des sentiments de « fidélité » inconscients à l’égard de leurs parents biologiques ont perduré. Ce travail aborde les relations conflictuelles qui accompagnent la difficile « transplantation affective » qui caractérise la relation adoptive et ses « crises de rejet ».
Approche sensori-motrice de l’enfant psychotique en crise
Authors: Devos Antoine
Published: April 2022

Les enfants violents, agités, sans limite, intolérants à la frustration, mettent en difficulté les équipes soignantes et éducatives en les confrontant à un profond sentiment d’impuissance qui conduit au rejet. Mais les concepts mêmes avec lesquels ces enfants sont décrits induisent des visions préjudiciables. Nous tenterons de montrer en quoi cette lecture biaise nos représentations et proposerons de mettre en rapport ces crises de violence avec la désorganisation de l’enfant psychotique, d’une part, et celle du bébé d’autre part. Nous chercherons également, grâce aux travaux de M.-C. Laznik, à comprendre l’impossible résolution de la crise de l’enfant en grande détresse avant de tenter une approche thérapeutique de la crise en suivant les grandes étapes du développement sensori-moteur telles que décrites par A. Bullinger. Une illustration clinique de résolution d’une crise violente chez un enfant psychotique et traumatisé montrera l’importance d’une telle conceptualisation pour la pratique.
Freud aurait-il été abusé ?
Authors: Sabourin Pierre , Sabourin Pierre
Published: April 2022

Les passages expurgés de la Correspondance Freud-Fliess révèlent que la question des abus intrafamiliaux s’est posée dès 1897, selon la lettre 120 de Freud (publiée par J.M. Masson). Une question s’impose : Freud en a-t-il lui-même été victime ? On retrouve des phrases de Freud censurées dans Naissance de la psychanalyse , avec des conséquences multiples sur les enseignements, entraînant la persistance du déni et le rejet des pathologies perverses adultes quand un enfant est victime. Les théories varient jusqu’au célèbre testament de 1938, l’ Abrégé de psychanalyse . Freud y reprend Ferenczi avec ses mots : « Abus sexuel sur les enfants par les adultes. » Freud place ce concept en tête des causes, « l’événement capital » à rechercher avant les séductions par frères ou sœurs, avant la scène primitive et avant le complexe d’Œdipe. Aujourd’hui nous sommes submergés par ces familles maltraitantes où l’inceste par l’adulte est passé à l’acte. Notre stratégie spécifique a fait ses preuves pour rétablir un enfant dans ses droits, par un travail en réseau et la place cruciale du système judiciaire.
L’infans dans l’adulte : pour une métapsychologie de l’écoute
Authors: Chiantaretto Jean-François
Published: April 2022

À envisager la métapsychologie comme méthode, Jean-Claude Rolland propose un ensemble de perspectives novatrices. Elles sont inspirées par la douleur : celle du renoncement chez l’infans à la relation d’objet originaire, celle du renoncement chez Freud à la métapsychologie conçue comme corpus scientifique définitivement constitué. Issue du contre-transfert, la pensée métapsychologique procède de l’activité fantasmatique de l’analyste en situation. Laquelle permet dans l’écoute de l’infantile d’entendre l’infans dans l’adulte : l’attente croyante et douloureuse au cœur du transfert de l’analysant.
La lente marche des collégiennes. Une pratique de mobilité accordée à la socialisation scolaire
Authors: Hugoo Vincent
Published: April 2022

En se fondant sur des observations et des entretiens, cet article analyse la place de la mobilité en groupe dans les socialisations scolaires et urbaines de collégiennes issues des milieux populaires. Parce qu’elle réunit des amies sur le chemin de l’école, la marche en groupe rend la contrainte scolaire plus acceptable, voire plus agréable. Parce qu’elle oblige collectivement, elle conforte la ponctualité des collégiennes. Cette pratique est aussi l’occasion de commencer à apprécier l’espace urbain. Ces jeunes filles étant étroitement contrôlées, les trajets en groupe sont au centre de leurs possibilités restreintes de sortie. En marchant lentement, les collégiennes agrandissent un petit espace-temps de liberté, prenant le temps de profiter de la ville.
Pratiques modales et socialisation : analyse du cas d’un conducteur régulier utilisateur d’une plateforme de covoiturage
Authors: Debroux Josette
Published: April 2022

C’est en mobilisant le modèle dispositionnaliste et contextualiste que nous avons cherché à comprendre le changement de mode de déplacement ou changement modal. À partir d’une étude de cas, celui de Guillaume, nous avons pu montrer que son engagement dans la pratique du covoiturage en tant que conducteur par l’intermédiaire de la plateforme BlaBlaCar résulte à la fois de la constitution, au cours de sa socialisation, des principales dispositions appelées par cette pratique (disposition à être économe, disposition ascétique, goût pour les échanges avec des inconnus) et du contexte (dimensions professionnelle, conjugale, familiale) agissant sur les déplacements et leur perception. La pratique intensive du covoiturage entre inconnus peut créer des dispositions, en renforcer d’autres. Un changement de perception du trajet lié à son motif peut également conduire à une mise en veille de dispositions fortement constituées.
Mobilités spatiales et mobilités de genre : enquête auprès des sous-officières et sous-officiers de la gendarmerie française
Authors: Elguezabal Eleonora
Published: April 2022

Les sous-officières et sous-officiers de gendarmerie sont contraint-e-s à des mobilités géographiques lors du recrutement et tout au long de leur carrière. Cet article explore les sens que revêtent ces mobilités spatiales en matière de socialisation professionnelle et de genre, du fait du modèle masculin viril qui domine dans le métier. Une « virilisation » est attendue des femmes (minoritaires), mais aussi des hommes, les masculinités étant plurielles. Les sous-officières et sous-officiers qui y sont les plus attaché-e-s sont celles et ceux qui sont les plus tourné-e-s vers les classes populaires, dont elles et ils sont majoritairement issu-e-s. Les gendarmes s’approprient les mobilités spatiales pour réaliser ces mobilités de genre, socialement situées, en les mettant à distance de leurs origines géographiques lors du recrutement. Ces mobilités spatiales produisent également des inégalités de genre, notamment car elles sont indispensables pour les avancements de carrière.
La socialisation aux mobilités pour raisons professionnelles : le cas des absences régulières du domicile
Authors: Vincent Stéphanie , Viry Gil
Published: April 2022

Le présent article s’intéresse à la socialisation aux mobilités pour raisons professionnelles en s’appuyant sur des données qualitatives de type récit de vie. Il montre comment la socialisation aux mobilités professionnelles pratiquées sous la forme d’absences fréquentes du domicile nécessitant des nuitées hors du foyer familial relève d’une socialisation primaire mais aussi de socialisations secondaires qui viennent parfois renforcer des dispositions acquises antérieurement. Si l’on observe des socialisations de transformation par l’expérience des déplacements professionnels, celles de renforcement semblent induire des pratiques de mobilité plus positives et plus pérennes. Si l’on retrouve la famille, les études ou les pairs comme cadres et contextes de cette socialisation mobilitaire, des dispositions activées dans la pratique de mobilités liées au travail proviennent d’autres domaines que celui-ci. Enfin, malgré l’intériorisation de dispositions, l’activation de ces dernières semble notamment dépendre des valeurs associées aux mobilités professionnelles, de l’identification à l’image du travailleur ou de la travailleuse mobile et des trajectoires familiales.
Le capital de mobilité : un capital bourdieusien ? L’expérience des membres de Médecins sans frontières
Authors: Joxe Ludovic
Published: April 2022

Dans quelle mesure le capital de mobilité peut-il être considéré comme un capital bourdieusien ? À partir d’une observation participante lors de onze missions avec l’organisation Médecins sans frontières (MSF) et d’une cinquantaine d’entretiens avec ses membres, nous montrons que, chez MSF, les expériences de mobilité sont accumulables, mobilisables, convertibles, dépréciables, transmissibles, et que, si ces expériences ne sont pas toujours mobilisées par ceux qui en disposent pour monter dans la hiérarchie formelle interne, elles leur permettent, en tout cas, de gagner en pouvoir de décision sur leur parcours à venir au sein de l’organisation. À ces divers titres, nous considérons que les expériences de mobilité constituent un capital bourdieusien, qualifié de capital de mobilité, décrivant non pas la part héréditaire ou transmissible du capital, mais au contraire, sa part vivante, celle accumulée au cours de la vie d’un individu, celle issue de ses socialisations successives.
Enseigner la controverse en urbanisme grâce à Show Me a Hero
Authors: Didier Sophie , Gomes Pedro
Published: April 2022

Certaines séries télévisées, au-delà de leur capacité à représenter des mondes urbains réels ou fantasmés, permettent aussi de rentrer dans les processus, les systèmes d’acteurs, les outils et les instruments qui président à la production urbaine. À ce titre, elles peuvent faire l’objet d’une utilisation pédagogique dans des enseignements en urbanisme, visant à rendre intelligibles ces systèmes culturellement ancrés de production de la ville. Cet article souligne l’intérêt d’utiliser Show Me a Hero , minisérie retraçant la bataille pour la déségrégation du logement à Yonkers, suburb de New York, dans un module d’enseignement sur les controverses en urbanisme. Son utilisation a articulé trois enjeux principaux : 1) la difficile mise en œuvre locale de la politique fédérale du logement, 2) la compréhension des spécificités des processus ségrégatifs et 3) l’objectivation des partis pris artistiques des auteurs comme condition à une analyse de la controverse.
L’urbanisme temporaire, nouvelle stratégie de renouvellement urbain ? L’utilisation de logements temporaires dans la réhabilitation de la Balfron tower, Londres
Authors: Dalis Sacha
Published: April 2022

L’urbanisme temporaire a le vent en poupe : à l’heure où le discours sur la ville recyclable et résiliente gagne en popularité et où l’utilisation du foncier disponible dans les centres-villes doit être maximisée, l’occupation éphémère, mais institutionnalisée d’espaces urbains vacants ou sous-utilisés avant leur transformation par un projet urbain peut sembler bienvenue. Cet article cherche à montrer que la dimension créative ou artistique mise en avant par beaucoup de projets d’urbanisme temporaire peut toutefois être utilisée pour augmenter la visibilité de certains sites et signaler ainsi leur transformation à venir auprès d’investisseurs extérieurs, participant activement au processus de renouvellement urbain. Pour ce faire, il étudie l’occupation éphémère d’un célèbre bâtiment de logement social de l’Est londonien, et montre par quels mécanismes ces logements temporaires ont pu contribuer à une stratégie plus large de renouvellement urbain du quartier, au détriment des habitants et des occupants temporaires eux-mêmes. Ce texte propose donc de recontextualiser spatialement, temporellement et socialement chaque projet d’urbanisme temporaire pour nuancer leur caractère alternatif et généralisable dans la ville de demain.
Stationary distribution, extinction, density function and periodicity of an n-species competition system with infinite distributed delays and nonlinear perturbations
Authors: Zhou Baoquan , Dai Yucong
Published: April 2022

In this paper, we examine an n-species Lotka-Volterra competition system with general infinite distributed delays and nonlinear perturbations. The stochastic boundedness and extinction are first studied. Then we propose a new \begin{document}$ p $\end{document}-stochastic threshold method to establish sufficient conditions for the existence of stationary distribution \begin{document}$ \ell(\cdot) $\end{document}. By solving the corresponding Fokker–Planck equation, we derive the approximate expression of the distribution \begin{document}$ \ell(\cdot) $\end{document} around its quasi-positive equilibrium. For the stochastic system with periodic coefficients, we use the \begin{document}$ p $\end{document}-stochastic threshold method again to obtain the existence of positive periodic solution. Besides, the related competition exclusion and moment estimate of species are shown. Finally, some numerical simulations are provided to substantiate our analytical results.

Authors: Tuan Nguyen Huy , Phuong Nguyen Duc , Thach Tran Ngoc
Published: April 2022

In this work, the following stochastic Rayleigh-Stokes equations are considered

   \begin{document}$ \begin{align*} \partial_t \big[ x(t)+f(t,x_\rho(t)) \big] = \big( A +\vartheta &\partial_t^\beta A \big) \big[ x(t)+f(t,x_\rho(t)) \big] \\ &+ g(t,x_\tau(t)) + B(t,x_\xi(t)) \dot{W}(t), \end{align*} $\end{document}

which involve the Riemann-Liouville fractional derivative in time, delays and standard Brownian motion. Under two different conditions for the non-linear external forcing terms, two existence and uniqueness results for the mild solution are established respectively, in the continuous space \begin{document}$ \mathcal{C}([-h,T];L^p(\Omega,V_q)) $\end{document}, \begin{document}$ p \ge 2 $\end{document}, \begin{document}$ q \ge 0 $\end{document}. Our study was motivated and inspired by a series of papers by T. Caraballo and his colleagues on stochastic differential equations containing delays.
Determining the global manifold structure of a continuous-time heterodimensional cycle
Authors: Hammerlindl Andy , Krauskopf Bernd , Mason Gemma , Osinga Hinke M.
Published: April 2022

A heterodimensional cycle consists of two saddle periodic orbits with unstable manifolds of different dimensions and a pair of connecting orbits between them. Recent theoretical work on chaotic dynamics beyond the uniformly hyperbolic setting has shown that heterodimensional cycles may occur robustly in diffeomorphisms of dimension at least three. We consider the first explicit example of a heterodimensional cycle in the continuous-time setting, which has been identified by Zhang, Krauskopf and Kirk [Discr. Contin. Dynam. Syst. A 32(8) 2825-2851 (2012)] in a four-dimensional vector-field model of intracellular calcium dynamics.

We show here how a boundary-value problem set-up can be employed to determine the organization of the dynamics in a neighborhood in phase space of this heterodimensional cycle, which consists of a single connecting orbit of codimension one and an entire cylinder of structurally stable connecting orbits between two saddle periodic orbits. More specifically, we compute the relevant stable and unstable manifolds, which we visualize in different projections of phase space and as intersection sets with a suitable three-dimensional Poincaré section. In this way, we show that, locally near the intersection set of the heterodimensional cycle, the manifolds interact as described by the theory for three-dimensional diffeomorphisms. On the other hand, their global structure is more intricate, which is due to the fact that it is not possible to find a Poincaré section that is transverse to the flow everywhere. More generally, our results show that advanced numerical continuation techniques enable one to investigate how abstract concepts â€" such as that of a heterodimensional cycle of a diffeomorphism â€" arise and manifest themselves in explicit continuous-time systems from applications.
Emergence of quasiperiodic regimes in a neutral delay model of flute-like instruments: Influence of the detuning between resonance frequencies
Authors: Terrien Soizic , Vergez Christophe , Fabre Benoît , de la Cuadra Patricio
Published: April 2022

Musical instruments display a wealth of dynamics, from equilibria (where no sound is produced) to a wide diversity of periodic and non-periodic sound regimes. We focus here on two types of flute-like instruments, namely a recorder and a pre-hispanic Chilean flute. A recent experimental study showed that they both produce quasiperiodic sound regimes which are avoided or played on purpose depending on the instrument. We investigate the generic model of sound production in flute-like musical instruments, a system of neutral delay-differential equations. Using time-domain simulations, we show that it produces stable quasiperiodic oscillations in good agreement with experimental observations. A numerical bifurcation analysis is performed, where both the delay time (related to a control parameter) and the detuning between the resonance frequencies of the instrument – a key parameter for instrument makers – are considered as bifurcation parameters. This demonstrates that the large detuning that is characteristic of prehispanic Chilean flutes plays a crucial role in the emergence of stable quasiperiodic oscillations.
On the divisors of natural and happy numbers: a study based on entropy and graphs
Authors: Mayer B.L. , Monteiro L.H.A.
Published: April 2022

The features of numerical sequences and time series have been studied by using entropies and graphs. In this article, two sequences derived from the divisors of natural numbers are investigated. These sequences are obtained either directly from the divisor function or by recursively applying the divisor function. For comparison purposes, analogous sequences formed from the divisors of happy numbers are also examined. Firstly, the informational entropy of these four sequences is numerically determined. Then, each sequence is mapped into graphs by employing two visibility algorithms. For each graph, the average degree, the average shortest-path length, the average clustering coefficient, and the degree distribution are calculated. Also, the links in these graphs are quantified in terms of the parity of the numbers that these links connect. These computer experiments suggest that the four analyzed sequences exhibit characteristics of quasi-random sequences.
A novel picture fuzzy Aczel-Alsina geometric aggregation information: Application to determining the factors affecting mango crops

Published: April 2022

Picture fuzzy (PF) sets are extremely reasonable to represent the uncertain, imprecise, and inconsistent information that exists in scientific and engineering fields. To meet decision makers' preference selection, the operational flexibility of aggregation operators shows its importance in dealing with the flexible decision-making problems in the PF environment. With assistance from Aczel-Alsina operations, we introduce the aggregation strategies of PFNs. We initially broaden the Aczel-Alsina norms to PF situations and present a few new operations of PFNs in view of which we build up a few new PF aggregation operators, for instance, the PF Aczel-Alsina weighted geometric, order weighted geometric, and hybrid weighted geometric operators. Furthermore, a decision support approach has been developed using the proposed aggregation operators under the PF environment. In this method, the aggregated results of each evaluated alternative are determined, and their score values are obtained. Then, all alternatives were ranked in decreasing order, and the best one was determined based on the highest score value. An illustrative example related to mango production is presented to investigate the most influential factor that resulted in mango production minimization. Finally, a comparison study was conducted on the proposed decision support method and the existing relative techniques. The result shows that the proposed method can overcome the insufficiency of lacking decision flexibility in the existing MAGDM method by the PF weighted geometric aggregation operators.
Blow-up of solutions to the coupled Tricomi equations with derivative type nonlinearities
Authors: Yao Jiangyan , Ming Sen , Han Wei , Zhang Xiuqing
Published: April 2022

This paper is concerned with blow-up results of solutions to coupled system of the Tricomi equations with derivative type nonlinearities. Upper bound lifespan estimates of solutions to the Cauchy problem with small initial values are derived by using the test function method (see the proof of Theorem 1.1) and iteration argument (see the proof of Theorem 1.2), respectively. Our main new contribution is that lifespan estimates of solutions to the problem in the sub-critical and critical cases which are connected with the Glassey conjecture are established. To the best knowledge of authors, the results in Theorems 1.1 and 1.2 are new.
Transmission dynamics of brucellosis with patch model: Shanxi and Hebei Provinces as cases
Authors: Qin Yaoyao , Pei Xin , Li Mingtao , Chai Yuzhen
Published: April 2022

Brucellosis is a zoonotic disease caused by Brucella, and it is an important infectious disease all over the world. The prevalence of brucellosis in the Chinese mainland has some spatial characteristics besides the temporal trend in recent years. Due to the large-scale breeding of sheep and the frequent transportation of sheep in various regions, brucellosis spreads wantonly in pastoral areas, and human brucellosis spreads from traditional pastoral areas and semi-pastoral areas in the north to non-pastoral areas with low incidence in the south. In order to study the influence of sheep immigration on the epidemic transmission, a patch dynamics model was established. In each patch, the sub-model was composed of humans, sheep and Brucella. The basic reproduction number, disease-free equilibrium and positive equilibrium of the model were discussed. On the other hand, taking Shanxi Province and Hebei Province as examples, we carried out numerical simulations. The results show that the basic reproduction numbers of Shanxi Province and Hebei Province are 0.7497 and 0.5022, respectively, which indicates that the current brucellosis in the two regions has been effectively controlled. To reduce brucellosis faster in the two provinces, there should be a certain degree of sheep immigration from high-infection area to low-infection areas, and reduce the immigration of sheep from low-infection areas to high-infection areas.

Biofilm formation at the level of a wound plays an important role in its chronicization. The difficulty of its eradication has driven research toward the discovery and synthesis of new molecules that can act on biofilm to promote wound healing. This narrative review focuses on alternative molecules that can act and promote the eradication of methicillin-resistant Staphylococcus aureus, taking into consideration its antibiotic resistance, virulence, tendency toward the tenacious colonization of wounds by biofilms, and its increased prevalence in both community and hospital settings. A selection of promising studies were reported, analyzing the in vitro and/or in vivo efficacy of bacteriophages, metal nanoparticles, RNAIII inhibiting peptide (RIP), synthetized RIP derivatives, proteinase K and hamamelitannin.
