Effect of Cosmic Mean Metallicity on the Supernovae Cosmology
Authors: Li Gexing , Li Zhihong
Published: November 2021

The initial metallicity of Type Ia Supernovae (SNe Ia) progenitor that is increasing with the cosmological chemical evolution will directly lead to a decrease of the 56Ni formed during the nucleosynthesis and then a varying standard candle. The variation may seriously affect our understanding of the evolving universe. In this work, we derived the relationships between 56Ni yield and metallicity in different progenitor channels. The evolution of the cosmic mean metallicity (CMM) was used to estimate the initial metallicity of progenitors. The effect of the delay times from the birth of progenitors to their explosion was also considered. The corrections of SNe Ia luminosity were estimated and the influences of the different progenitor channels and CMM evolution rates were examined. Several important cosmological parameters were updated according to the luminosity corrections.

We report the discovery of two kinematically anomalous atomic hydrogen (H i) clouds in M 100 (NGC 4321), which was observed as part of the Deciphering the Interplay between the Interstellar medium, Stars, and the Circumgalactic medium (DIISC) survey in H i 21 cm at 3.3 km s−1 spectroscopic and 44″ × 30″ spatial resolution using the Karl G. Jansky Very Large Array.

The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

These clouds were identified as structures that show significant kinematic offsets from the rotating disk of M 100. The velocity offsets of 40 km s−1 observed in these clouds are comparable to the offsets seen in intermediate-velocity clouds (IVCs) in the circumgalactic medium (CGM) of the Milky Way and nearby galaxies. We find that one anomalous cloud in M 100 is associated with star-forming regions detected in Hα and far-ultraviolet imaging. Our investigation shows that anomalous clouds in M 100 may originate from multiple mechanisms, such as star formation feedback-driven outflows, ram pressure stripping, and tidal interactions with satellite galaxies. Moreover, we do not detect any cool CGM at 38.8 kpc from the center of M 100, giving an upper limit of N(H i) ≤1.7 × 1013 cm−2 (3σ). Since M 100 is in the Virgo cluster, the nonexistence of neutral/cool CGM is a likely pathway for turning it into a red galaxy.
The Structural Connection between Coronal Mass Ejection Flux Ropes near the Sun and at 1 au
Authors: Xie H. , Gopalswamy N. , Akiyama S.
Published: November 2021

We have performed the first comprehensive statistical analysis comparing flux rope (FR) structures of coronal mass ejections (CMEs) near the Sun and at 1 au, using Solar and Heliospheric Observatory and Solar Terrestrial Relations Observatory measurements for the two full solar cycles 23 and 24. This study aims to investigate the physical connection of 102 magnetic FRs among solar source regions, CMEs in the extended corona, and magnetic clouds (MCs) near Earth. Our main results are as follows: (1) We confirmed that the hemispheric-helicity rule holds true for ∼87% of our 102 events. For the 13 events that do not follow this rule, the FR axis directions and helicity signs can be inferred from soft X-ray and extreme ultraviolet images and magnetogram data in the source regions (e.g., coronal arcade skews, Fe xii stalks, sigmoids, and magnetic tongues). (2) Around 25% of the 102 events have rotations >40° between the MC and CME-FR axial orientations. (3) For ∼56% of these rotational events, the FR rotations occurred within the COR2 field of view, which can be predicted from the CME tilts obtained from FR fitting models. In addition, we found that for 89% of the 19 stealth CMEs under study, we were able to use coronal neutral line locations and tilts to predict the FR helicity and its axial direction in the MCs. The above results should help improve the prediction of FR structures in situ. We discuss their implications on space weather forecasts.
Simulating the Negative Jet Feedback Mechanism in Common Envelope Jet Supernovae
Authors: Grichener Aldana , Cohen Coral , Soker Noam
Published: November 2021

We use the stellar evolution code MESA to study the negative jet feedback mechanism in common envelope jet supernovae (CEJSNe), in which a neutron star (NS) launches jets in the envelope of a red supergiant (RSG). We find that the feedback reduces the mass accretion rate to be χ
j ≃ 0.04–0.3 times the mass accretion rate without the operation of jets. We mimic the effect of the jets on the RSG envelope by depositing the energy that the jets carry into the envelope zones outside the NS orbit. The energy deposition inflates the envelope, therefore reducing the density in the NS vicinity, which in turn reduces the mass accretion rate in a negative feedback cycle. In calculating the above values for the negative jet feedback coefficient (the further reduction in the accretion rate) χ
j, we adopt the canonical ratio of jet power to actual accretion power of 0.1, and the results of numerical simulations that show the actual mass accretion rate to be a fraction of 0.1–0.5 of the Bondi–Hoyle–Lyttleton mass accretion rate.
Forward Modeling of Simulated Transverse Oscillations in Coronal Loops and the Influence of Background Emission
Authors: Shi Mijie , Van Doorsselaere Tom , Antolin Patrick , Li Bo
Published: November 2021

We simulate transverse oscillations in radiatively cooling coronal loops and forward-model their spectroscopic and imaging signatures, paying attention to the influence of background emission. The transverse oscillations are driven at one footpoint by a periodic velocity driver. A standing kink wave is subsequently formed and the loop cross section is deformed due to the Kelvin–Helmholtz instability, resulting in energy dissipation and heating at small scales. Besides the transverse motions, a long-period longitudinal flow is also generated due to the ponderomotive force induced slow wave. We then transform the simulated straight loop to a semi-torus loop and forward-model their spectrometer and imaging emissions, mimicking observations of Hinode/EIS and SDO/AIA. We find that the oscillation amplitudes of the intensity are different at different slit positions, but are roughly the same in different spectral lines or channels. X-t diagrams of both the Doppler velocity and the Doppler width show periodic signals. We also find that the background emission dramatically decreases the Doppler velocity, making the estimated kinetic energy two orders of magnitude smaller than the real value. Our results show that background subtraction can help recover the real oscillation velocity. These results are helpful for further understanding transverse oscillations in coronal loops and their observational signatures. However, they cast doubt on the spectroscopically estimated energy content of transverse waves using the Doppler velocity.

Electron heating/acceleration in the foreshock, by which electrons may be energized beyond thermal energies prior to encountering the bow shock, is very important for the bow shock dynamics. And then these electrons would be more easily injected into a process like diffusive shock acceleration. Many mechanisms have been proposed to explain electrons heating/acceleration in the foreshock. Magnetic reconnection is one possible candidate. Taking advantage of the Magnetospheric Multiscale mission, we present two magnetic reconnection events in the dawnside and duskside ion foreshock region, respectively. Super-Alfvénic electron outflow, demagnetization of the electrons and the ions, and crescent electron distributions in the plane perpendicular to the magnetic field are observed in the sub-ion-scale current sheets. Moreover, strong energy conversion from the fields to the plasmas and significant electron temperature enhancement are observed. Our observations provide direct evidence that magnetic reconnection could occur in the foreshock region and heat/accelerate the electrons therein.
Electron-only Reconnection in an Ion-scale Current Sheet at the Magnetopause

Published: November 2021

In the standard model of magnetic reconnection, both ions and electrons couple to the newly reconnected magnetic field lines and are ejected away from the reconnection diffusion region in the form of bidirectional burst ion/electron jets. Recent observations propose a new model: electron-only magnetic reconnection without ion coupling in an electron-scale current sheet. Based on the data from the Magnetospheric Multiscale (MMS) mission, we observe a long-extension inner electron diffusion region (EDR) at least 40 d
i away from the X-line at the Earth’s magnetopause, implying that the extension of EDR is much longer than the prediction of the theory and simulations. This inner EDR is embedded in an ion-scale current sheet (the width of ∼4 d
i, d
i is ion inertial length). However, such ongoing magnetic reconnection was not accompanied with burst ion outflow, implying the presence of electron-only reconnection in an ion-scale current sheet. Our observations present a new challenge for understanding the model of standard magnetic reconnection and the electron-only reconnection model in an electron-scale current sheet.
Measurement and Monitoring of Health Care Worker Aggression Exposure
Authors: Iennaco Joanne , Dixon Jane , Whittemore Robin , Bowers Len
Published: November 2021

Aggression exposure is highly prevalent in healthcare workers, and is a complex problem that negatively impacts patient and worker safety and health. Typically only events of high severity (e.g., use of physical restraint or incident reports) are monitored in healthcare settings. Unfortunately, these events are likely a small fraction of all aggressive events that range from verbal to physical. Improved measurement and monitoring of healthcare worker aggression exposure may lead to improved patient and worker safety and health. This article provides an overview of aggression exposure in healthcare and reviews the measurement of aggression, including challenges and common measures. Discussion of a pilot study presents insights gained from using a novel measure of aggression, handheld counters. The conclusion offers implications for research and clinical practice.
A Framework for Translating Workplace Violence Intervention Research into Evidence-Based Programs
Authors: McPhaul Kathleen , London Matthew , Lipscomb Jane
Published: November 2021

Workplace violence, a dangerous and complex occupational hazard in the modern health care work environment, presents challenges for nurses, other health care employees, management, labor unions, and regulators. Violence from patients, visitors, and coworkers is often tolerated and explained as part of the job in the fast-paced, stressful health care delivery workplace. Addressing violence in health care requires very purposeful organizational processes conducted by very specific organizational structures. The strength of the scientific evidence for workplace violence prevention strategies is well past the “emerging” evidence stage but has not achieved the “unequivocal” stage. It is unlikely that workplace violence interventions will be tested using randomized controlled experimental conditions. Consequently, educated and aware nurses often provide key leadership for organizations undertaking the development of workplace violence prevention programs, but must do so using local evidence generated at the facility level. In some cases, tools such as state regulations and federal workplace safety policies provide important impetus and support for nurses and hospitals undertaking these transformational programs. This article provides background information about workplace violence and offers a framework for developing comprehensive workplace violence prevention programs built on the existing scientific evidence, regulatory guidance, and locally generated practice evidence
The Impact of Emerging Technology on Nursing Care: Warp Speed Ahead
Authors: Huston Carol
Published: November 2021

While myriad forces are changing the face of contemporary healthcare, one could argue that nothing will change the way nursing is practiced more than current advances in technology. Indeed, technology is changing the world at warp speed and nowhere is this more evident than in healthcare settings. This article identifies seven emerging technologies that will change the practice of nursing; three skill sets nurses will need to develop to acquire, use, and integrate these emerging technologies; and four challenges nurse leaders will face in integrating this new technology.
Nursing Intellectual Capital Theory: Implications for Research and Practice
Authors: Covell Christine , Sidani Souraya
Published: November 2021

Due to rising costs of healthcare, determining how registered nurses and knowledge resources influence the quality of patient care is critical. Studies that have investigated the relationship between nursing knowledge and outcomes have been plagued with conceptual and methodological issues. This has resulted in limited empirical evidence of the impact of nursing knowledge on patient or organizational outcomes. The nursing intellectual capital theory was developed to assist with this area of inquiry. Nursing intellectual capital theory conceptualizes the sources of nursing knowledge available within an organization and delineates its relationship to patient and organizational outcomes. In this article, we review the nursing intellectual capital theory and discuss its implications for research and practice. We explain why the theory shows promise for guiding research on quality work environments and how it may assist with administrative decision-making related to nursing human resource management and continuing professional development.
Hospital-Based Fall Program Measurement and Improvement in High Reliability Organizations
Authors: Quigley Patricia , White Susan
Published: November 2021

Falls and fall injuries in hospitals are the most frequently reported adverse event among adults in the inpatient setting. Advancing measurement and improvement around falls prevention in the hospital is important as falls are a nurse sensitive measure and nurses play a key role in this component of patient care. A framework for applying the concepts of high reliability organizations to falls prevention programs is described, including discussion of the core characteristics of such a model and determining the impact at the patient, unit, and organizational level. This article showcases the components of a patient safety culture and the integration of these components with fall prevention, the role of nurses, and high reliability.
À propos d’acrotères delphiques

Published: November 2021

Un réexamen des acrotères du trésor des Athéniens à Delphes à la suite d’un dessin de restitution de la façade de l’édifice a conduit à revoir la disposition des figures d’acrotères de plusieurs édifices de ce site, dans la suite de l’article publié en 1993 par J. Marcadé. Les exigences de la représentation graphique, les nécessités matérielles de la mise en place de ces figures ont amené à mettre en cause certaines restitutions antérieures et à proposer de nouvelles attributions. Ce réexamen s’accompagne de considérations sur l’organisation des décors de façade.
Des Néréides aux Eliyãna entre réception et élaboration des statues d’entrecolonnement du tombeau d’Arbinas de Xanthos (Lycie)
Authors: Colas-Rannou Fabienne
Published: November 2021

Cet article discute l’interprétation des statues d’entrecolonnement du tombeau d’Arbinas de Xanthos (vers 390-380 avant J.-C.). Après avoir détaillé les caractéristiques stylistiques et iconographiques des statues, l’auteur rappelle l’histoire de leur réception depuis le xix e  siècle et la naissance du nom « monument des Néréides ». Si des parallèles stylistiques avec la sculpture grecque sont évidents, les écarts iconographiques avec les images grecques de Néréides et une série d’inscriptions conduisent l’auteur à défendre l’idée de la représentation des divinités lyciennes nommées Eliyãna, qui révèle la permanence d’un substrat anatolien. Cette lecture est étayée par une proximité avec les iconographies hittite et néo-hittite.
La construction sociale du sexe biologique en débat
Authors: Charpentier Arto
Published: November 2021

Le sexe biologique est-il une construction sociale ? En avançant cette thèse dans les années 1990, des féministes ont suscité d’innombrables débats, qui portent à la fois sur le sens de cet énoncé, et sur les implications métaphysiques et épistémologiques qui en découlent. Le but de cet article est de les revisiter en partant de la controverse qui a opposé Judith Butler et Sally Haslanger à ce sujet. Leur discussion engage non seulement la signification à accorder à la notion de construction sociale, mais aussi plus largement la compatibilité d’une approche constructiviste avec une forme de réalisme scientifique, qui soit capable de faire droit en même temps à la réalité objective des phénomènes de sexuation et à la diversité des cadres conceptuels en partie contingents élaborés pour les appréhender.
Pour une philosophie des élections

Published: November 2021

Malgré la place centrale qu’elles occupent dans notre vie politique, les élections ont, jusqu’à présent, peu retenu l’attention des philosophes. L’article plaide en faveur d’une approche philosophique des élections. Il fait état des difficultés que le projet de faire une philosophie des élections rencontre, mais aussi des espoirs qu’il laisse entrevoir : en changeant notre regard sur les élections, en les considérant, non plus comme une solution, mais comme un problème, nous pourrions, par là même, revivifier la démocratie.
Les relations charnelles entre l’adulte et l’enfant sont-elles légitimes ?
Authors: Liotta Daniel
Published: November 2021

Les rapports charnels entre enfant et adulte sont-ils légitimes ? Le discours de la sexualité propose deux réponses opposées, comme le manifestent la psychiatrie et la pensée de Schérer ; mais ce discours doit être récusé en raison de son arbitraire anthropologique. Fonder la réponse, qui est négative, suppose d’affronter le problème du consentement charnel possible de l’enfant, ainsi que le fait Foucault. Mais, en opposition à ses conclusions, il faut penser une expérience fondamentale de l’enfance irréductible aux objectivations anthropologiques, qu’il convient d’articuler à une axiologie de la responsabilité. Précisément, il convient de déterminer le principe de l’immaturité enfantine, et la différence axiologique entre les consentements enfantins et les consentements adultes.
Plier la semaine au rythme du politique ?
Authors: Conord Fabien
Published: November 2021

De la Révolution française à la Seconde Guerre mondiale, plusieurs essais de redécoupage du temps social voient le jour ou sont simplement esquissés, en France mais aussi en Union soviétique ou même dans les anciens empires musulmans en voie de modernisation. Cet article retrace l’histoire de ces tentatives, en expose les motivations mais aussi les résistances que rencontrent ces politiques qui bouleversent l’organisation sociale en essayant de se soustraire au référentiel religieux. Il constate l’échec final de la plupart de ces expériences, qui demeurent limitées dans le temps (une douzaine d’années en France comme en URSS) et peinent à passer de la sphère politique aux réalités de la vie populaire.
Jours tranquilles à Matignon : gérer la semaine de Pierre Mauroy entre Lille et Paris
Authors: Guigo Pierre-Emmanuel
Published: November 2021

Véritable « enfer » selon le titre de l’ouvrage que Raphaëlle Bacqué a dédié aux Premiers ministres de la V e  République, Matignon soumet ses occupants à un rythme effréné. L’étude des agendas de Pierre Mauroy et du journal de marche de l’aide de camp du Premier ministre permet toutefois de voir que la semaine de celui qui est aussi maire de Lille est très structurée avec des rendez-vous récurrents fixés avec ses ministres, le chef de l’État, ses collaborateurs ou à l’Assemblée nationale. L’urgence peut bien évidemment s’imposer, notamment lors des grandes décisions économiques (dévaluation de juin 1982, « tournant de la rigueur »), des réformes structurelles, mais plus qu’un chambardement de l’organisation, c’est un agenda qui s’allonge, profitant des interstices laissés vacants. L’originalité de la semaine de Pierre Mauroy à Matignon réside dans ses week-ends qu’il consacre quasi systématiquement à un retour dans sa ville de Lille dont il continue à assumer les tâches de maire. Cette ubiquité entre Lille et Paris est rendue possible par des moyens logistiques exceptionnels.
Temps organisé ou temps dilaté
Authors: Fau-Vincenti Véronique
Published: November 2021

L’organisation du temps et des semaines dans les asiles et hôpitaux psychiatriques a été précédée par un ordonnancement architectural des établissements publics qui se sont imposés comme « ville dans la ville ». Ces cités thérapeutiques ont renfermé des enfants, des femmes et des hommes, dont la plupart en perdition sociale. Afin de les soigner et dans l’espoir de leur permettre de réintégrer le monde hors les murs de l’asile, le premier traitement qui leur ait été proposé consistait en un emploi du temps règlementé. Travail au quotidien et loisirs aux interstices, les semaines de milliers d’interné·e·s déclaré·e·s « valides » se trouvèrent calquées sur celles de millions de Françaises et de Français salarié·e·s. Néanmoins, pour d’autres interné·e·s placé·e·s en cellule d’isolement en raison de leur comportement, les jours, les semaines ou les mois accoucheront d’un temps dilaté et inoccupé qui leur fera perdre le sens du temps et de ses rituels institués.
Temps de l’école, rythme du foyer
Authors: Guillier Béatrice
Published: November 2021

À la fin du xix e  siècle, des maisons d’édition spécialisées dans les manuels scolaires lancent de nombreux journaux illustrés destinés aux petites filles de moins de quinze ans. Ils connaissent immédiatement un fort succès. Cet article explore le rôle joué par le format hebdomadaire de ces publications dans l’incorporation des normes temporelles par les petites filles du début du xx e  siècle. Les illustrés témoignent du contrôle croissant par les institutions du temps de travail de la population, à présent segmenté en semaine de travail, et rendent compte de la pression exercée sur l’emploi du temps des filles par les rythmes imposés à l’école et à la maison. Leur étude éclaire la position doublement dominée des petites filles, contraintes en tant que femmes et en tant qu’enfants. La pratique des travaux d’aiguille, point d’orgue de leur apprentissage, participe de la construction de la petite fille en tant qu’« être périodique » inscrit dans un rythme cyclique.
Après la bataille ?

Published: November 2021

Cet article porte sur la gestion du temps de la semaine dans les hebdomadaires d’information qui connaissent le risque d’avoir un temps de retard, par rapport aux quotidiens et aux autres médias (radio, télévision). L’article présente les deux modèles historiques français d’hebdomadaires d’information, les « hebdomadaires de lecture » et les « miroirs photographiques » jusqu’à l’instauration en 1964 du format newsmagazine . Il montre les procédés poétiques inventés par les hebdomadaires pour concurrencer avec succès les quotidiens et les autres médias : événementialisation, éditorialisation, illustration. Il insiste enfin sur la présence à côté de l’actualité hebdomadaire d’une semaine cycle avec un traitement de l’actualité récursif qui accompagne les nouveaux rythmes collectifs et professionnels, qui construit des communautés et véhicule des styles de vie.
Une histoire de la semaine sportive en Europe occidentale
Authors: Dietschy Paul
Published: November 2021

L’invention de la semaine sportive accompagne autant la transformation des exercices physiques que celle du temps social. Avec l’industrialisation et l’urbanisation disparaissent les jeux traditionnels souvent violents associés au calendrier religieux ou s’immisçant dans le temps poreux du travail. Les sports se développent pour occuper le repos compensateur d’un labeur devenu intense et éreintant. La semaine footballistique se cantonne d’abord au samedi et au dimanche quand les épreuves hippiques et cyclistes débordent du week-end. Le temps hebdomadaire du sport est autant un moment pour soi qu’un lieu de contrôle et d’édification pour les pédagogues, le clergé, l’armée, le patronat et les régimes totalitaires et autoritaires. Les transformations technologiques et sociales du second xx e siècle ont pour conséquence la dilatation de la semaine sportive et son investissement par les femmes et les seniors. Le sport est partie prenante du temps partiellement poreux de la semaine postmoderne.
Optimal pre-sale policy for deteriorating items
Authors: Zhao Lianxia , Qiao Hui , An Qi
Published: November 2021

Pre-sale policy is a frequently-used sales approach for deteriorating products, e.g, fruits, vegetables, seafood, etc. In this paper, we consider an EOQ inventory model under pre-sale policy for deteriorating products, in which the demand of pre-sale period depends on price and pre-sale horizon, and the demand of spot-sale period depends on the price and stock level. Optimal pricing decisions and economic order quantity are also provided. We compare pre-sale model with a benchmark inventory model in which all the products are sold in spot-sale period. Theoretical results are derived to show the existence and uniqueness of the optimal solution. Numerical experiments are carried out to to illustrate the theoretical results. And sensitivity analysis is conducted to identify conditions under which the pre-sale policy is better off than the spot-sale only policy.
Understanding Thermoelectrics Through Carrier and Phonon Transport
Authors: KIM Kyung Tae
Published: November 2021

Solid state energy conversion using thermoelectric (TE) phenomena has attracted great interest in power generation by using waste heat and active cooling/heating from electricity. Since first observation of the Seebeck and Peltier effect in the early 1820s, the TE phenomena has been applied in limited fields due to difficulties during the last two centuries in controling performance, which is related to both the carrier and the phonon transport behaviors. This article briefly introduces not only technological research issues for universal use of thermoelectrics but also the latest strategy for applications from the viewpoint of materials.

Published: November 2021

The emergence of the Covid-19 Pandemic has defined more dependence upon the involvement of ICT in EFL Class. This study investigates the integration of ICT in English teaching practices among teachers in the EFL context in a new normal setting.  To achieve the aim of the study, a mixed-method approach has been applied.  Thirty- two EFL teachers of junior high school who joined as members of Musyarawah Guru Mata Pelajaran (MGMP-English Teacher Regional Forum) in Bitung City, North Sulawesi, Indonesia. They have been selected as the participants for their familiarity for teaching English using the technological tools and for their teaching experience. A quantitative inquiry is carried out by distributing a questionnaire of twenty-three items adapted from two questionnaires namely those of Mailizar & Fan, and Almalki. Due to the Pandemic, the questionnaires are distributed by utilizing Google form, and then, the responses are analyzed by using SPSS tool. The qualitative data are in the forms of interview as the verification to deepen the discussion of the quantitative results. The semi-structured interview is performed and the responses are analyzed in triangulation method. The study showed that teachers’ knowledge and perception toward the integration of ICT is high.  Further, this study found that despite acknowledging the importance of the enjoyment of integrating the ICT in the learning process, teachers identified the aspects of learners’ lack of technological literacy and infrastructure, and lack of motivation can be barriers for the success of the ICT integration. For such challenges, the study also revealed that teachers attempt to practice a sort of home visit and invitation learning and encouraging the making of soft skills for class activity management. These findings expectedly contribute to define the role of ICT in the current pandemic era.

Multi-Objective Big Data View Materialization Using MOGA
Authors: Kumar Akshay , Kumar T. V. Vijay
Published: November 2021

The COVID 19 Pandemic, has resulted in large scale of generation of Big data. This Big data is heterogeneous and includes the data of people infected with corona virus, the people who were in contact of infected person, demographics of infected person, data on corona testing, huge amount of GPS data of people location, and large number of unstructured data about prevention and treatment of COVID 19. Thus, the pandemic has resulted in producing several Zeta bytes of structured, semi-structured and unstructured data. The challenge is to process this Big data, which has the characteristics of very large volume, brisk rate of generation and modification and large data redundancy, in a time bound manner to take timely predictions and decisions. Materialization of views for Big data is one of the ways to enhance the efficiency of processing of the data. In this paper, Big data view selection problem is addressed, as a bi-objective optimization problem, using Multi-objective genetic algorithm.

Published: November 2021

The Casse-tête board puzzle consists of an n×n grid covered with n^2 tokens. m<n^2 tokens are deleted from the grid so that each row and column of the grid contains an even number of remaining tokens. The size of the search space is exponential. This study used a genetic algorithm (GA) to design and implement solutions for the board puzzle. The chromosome representation is a matrix of binary permutations. Variants for two crossover operators and two mutation operators were presented. The study experimented with and compared four possible operator combinations. Additionally, it compared GA and simulated annealing (SA)-based solutions, finding a 100% success rate (SR) for both. However, the GA-based model was more effective in solving larger instances of the puzzle than the SA-based model. The GA-based model was found to be considerably more efficient than the SA-based model when measured by the number of fitness function evaluations (FEs). The Wilcoxon signed-rank test confirms a significant difference among FEs in the two models (p=0.038).
Vehicle Type Classification Using Hybrid Features and a Deep Neural Network
Authors: N. Sathyanarayana , Narasimhamurthy Anand M.
Published: November 2021

Currently, considerable research has been done in vehicle type classification, especially due to the success of deep learning in many image classification problems. In this research, a system incorporating hybrid features is proposed to improve the performance of vehicle type classification. The feature vectors are extracted from the pre-processed images using Gabor features, a histogram of oriented gradients and a local optimal oriented pattern. The hybrid set of features contains complementary information that could help discriminate between the classes better, further, an ant colony optimizer is utilized to reduce the dimension of the extracted feature vectors. Finally, a deep neural network is used to classify the types of vehicles in the images. The proposed approach was tested on the MIO vision traffic camera dataset and another more challenging real-world dataset consisting of videos of multiple lanes of a toll plaza. The proposed model showed an improvement in accuracy ranging from 0.28% to 8.68% in the MIO TCD dataset when compared to well-known neural network architectures.
A Radial Estimation-of-Distribution Algorithm for the Job-Shop Scheduling Problem
Authors: Pérez-Rodríguez Ricardo
Published: November 2021

The job-shop environment has been widely studied under different approaches. It is due to its practical characteristic that makes its research interesting. Therefore, the job-shop scheduling problem continues being attracted to develop new evolutionary algorithms. In this paper, we propose a new estimation of distribution algorithm coupled with a radial probability function. The aforementioned radial function comes from the hydrogen element. This approach is proposed in order to build a competitive evolutionary algorithm for the job-shop scheduling problem. The key point is to exploit the radial probability distribution to construct offspring, and to tackle the inconvenient of the EDAs, i.e., lack of diversity of the solutions and poor ability of exploitation. Various instances and numerical experiments are presented to illustrate, and to validate this novel research. The results, obtained from this research, permits to conclude that using radial probability distributions is an emerging field to develop new and efficient EDAs.
Does the expansion of the species' breeding range also involve the establishment of new migratory routes and new wintering ranges? The case of the citrine wagtail Motacilla citreola (Pallas, 1776)
Authors: Ferlini Flavio , Malling Olsen Klaus
Published: November 2021

From the second half of the 20th century, some Asian or Eastern European species expanded their breeding range westward. These include red-flanked bluetail Tarsiger cyanurus, black-headed bunting Emberiza melanocephala, common rosefinch Carpodacus erythrinus, and citrine wagtail Motacilla citreola. All of these species are long-range migratory species that historically have their own wintering ranges concentrated in Southern Asia. Although migratory behavior is mainly controlled by genetic factors, there is evidence of a high degree of flexibility and adaptability. Therefore, in the event of specific environmental changes, the genetic basis for a rapid and diverse micro-evolutionary development that affects the future migration patterns of birds is already in place. Possible adaptations also include changes to migratory directions and the choice of new and closer winter quarters. It is therefore prudent to ask whether the long-range migratory species that have expanded their breeding range westward in Europe have also established new migration routes and wintering ranges. This research shows that over the last few decades, the wintering area of Motacilla citreola has expanded westwards, including significantly the Middle East and, to a lesser extent, Africa and Europe. Especially in the activation of the most western routes, a fundamental role was played by the phenomenon of post-fledging dispersal, manifested by young who, as also observed in other Asian passerines (e.g., Pallas's warbler Phylloscopus proregulus, yellow-browed warbler Phylloscopus inornatus, pine bunting Emberiza leucocephalos), in autumn moved in different directions than the typical migratory route of their species. The Middle East and the neighboring Horn of Africa are progressively increasing in relevance as an additional area for the wintering of the species as a whole. Similarly, if in Europe the expansion of the breeding range towards the west continues in the future, West Africa, reached through Gibraltar, could become important as additional wintering ranges. In analogy with what is being observed for the western yellow wagtail Motacilla flava, Europe itself is also becoming part of the wintering range of the species. In fact, there is an increase in cases of wintering not only in the south of the continent, but there is also a progression towards the north.

Current research progress of isoflurane in cerebral ischemia/reperfusion injury
Authors: Chen Shu-Jun , Yuan Xia-Qing , Xue Qun , Lu Hai-Feng , Chen Gang
Published: November 2021

Cerebral ischemia/reperfusion injury is an important factor leading to poor prognosis in ischemic stroke patients. Therefore, it is particularly important to find effective remedial measures to promote the health of patients to return to society. Isoflurane is a safe and reliable anesthetic gas with a long history of clinical application. In recent years, its protection function to human body has been widely recognized, and nowadays isoflurane for cerebral protection has been widely studied, and the stable effect of isoflurane has satisfied many researchers. Basic studies have shown that isoflurane’s protection of brain tissue after ischemia/reperfusion involves a variety of signaling pathways and effector molecules. Even though many signaling pathways have been described, more and more studies focus on exploring their mechanisms of action, in order to provide strong evidence for clinical application. This could prompt the introduction of isoflurane therapy to clinical patients as soon as possible. In this paper, several confirmed signaling pathways will be reviewed to find possible strategies for clinical treatment.

There is a constant search for bleaching treatments that can offer greater safety with fewer adverse effects, especially in the techniques performed in the office, which usually employ hydrogen peroxide in high concentrations (35% to 40%) that are not recommended by some international control agencies. This in vitro study evaluated the color change after tooth bleaching with the use of ozone and a 10% ozonized carbamide peroxide bleaching treatment for in-office use. Thirty molars were allocated (n = 10): three applications of ozone (1 hour every 3 days); three applications of 10% ozonized carbamide peroxide (1 hour every 3 days); 10% carbamide peroxide agent (8 hours a day for 7 days). The teeth were mounted on a plaster model to simulate the dental arch, and trays made of silicone were used for the application of the bleaching agents and to allow ozone to enter through. The ozone concentration used was 60 μg/mL, with an oxygen flow of 0.25 L/min. The values of color change showed no significant differences among treatments. The variations in the parameters over time, as well as the values of ΔE
ab, ΔE
00, and WI
D, showed that there was no significant difference among the three treatments. The use of ozone and 10% ozonized carbamide peroxide for in-office use was effective for tooth bleaching with clinically perceptible and acceptable color alterations. The study was approved on September 10, 2019 by the São Leopoldo Mandic Ethics Research Committee (CAAE No. 17711719.4.0000.5374).

Medical effects of hydrogen have been reported in many studies. Due to difficulties in measuring hydrogen concentration in vivo after intake and high explosive risks of hydrogen, studies about dose-response relationships and tissue concentrations of hydrogen are few. Here, for the first time, we monitored real-time hydrogen concentrations in different tissues in rats including brain, liver, spleen, kidney, thigh muscle, inguinal white adipose tissue, and gonadal white adipose tissue after inhaling different concentrations of hydrogen (4%, 42%, and 67%) using an electrochemical sensor. Hydrogen concentrations in the same tissue showed a dose-dependent response. The equilibrium concentration values were highest in the brain and lowest in the thigh muscle. The saturation and desaturation curves changed more slowly in the thigh muscle and white adipose tissues than in other tissues. These results provide fundamental information for the selection of hydrogen dose applications in basic research and clinical trials. The experiments were approved by the Laboratory Animal Ethics Committee of Shandong First Medical University & Shandong Academy of Medical Sciences (No. 2020-1028) on March 18, 2020.

Quantitative and qualitative evaluation of perception of medical faculty toward competency-based medical education for undergraduate curriculum
Authors: Teli Anita , Harakuni Sheetal , Kamat Chaitanya
Published: November 2021

INTRODUCTION:

Competency-based medical education (CBME) is an outcome-based education system. There is a big shift in roles and responsibilities of teachers, students, and teaching methods. This study was planned to evaluate the faculty perceptions and concepts toward the CBME and its implementation.

METHODOLOGY:

This is a mixed-method study with elements of qualitative (free listing and pile sorting) and quantitative (three-point Likert scale) assessment of faculty perceptions on CBME designed through Google Forms, and the responses obtained were analyzed. Three hundred faculties were recruited for a quantitative study, out of which 125 responded. For qualitative analysis, the preclinical faculties (n = 20) were recruited. Percentages for the responses were calculated. Free-listing and pile-sorting exercise data were analyzed in Visual Anthropac 1.0 software.

RESULTS:

The responses from participants showed encouraging analysis. A total of 128 faculty members responded that a response rate was 43%. Thirty-eight responses were obtained through interview pertaining to the concepts (qualitative study) of CBME. From the free-listed items or responses, the items were selected based on salience or ranking or investigator's judgment for pile sorting to understand clustering of responses.

CONCLUSION:

Majority of the faculties had a positive perception about the implementation of CBME. Coordination between the Preclinical, paraclinical and clinical departments and proper lesson plan were the factors facilitating effective implementation. Inadequate faculty training and unanticipated holidays were the challenges for the implementation of CBME. Proper faculty training is the utmost important aspect in the effective implementation.

Background:

Digital physiotherapy in line with global health coverage has become a salient field of physiotherapy practice where routine and innovative forms of information and communications technology are employed with the aim of facilitating effective delivery and access to physiotherapeutic services and resources. This study evaluated and determined the socio-demographic correlates of awareness, acceptability, and willingness-to-pay (WTP) for digital physiotherapy among patients.

Materials and Methods:

A total of 92 consenting patients who were 18 years and older responded in this cross-sectional study. An adapted tool on awareness, acceptability, and WTP for telemedicine services was adapted for use in this study. Data were analyzed using descriptive statistics of mean, standard deviation, and percentages; inferential statistics of Chi-square was used for test of association. Alpha level was set at P < 0.05.

Results:

The mean age of the respondents was 52.40 ± 15.62 years. There was a high rate of unawareness (91.3%), moderate-to-high acceptability (87.0%) and high WTP (88.0%) for digital physiotherapy, respectively. There was no significant association between the socio-demographic factors and each of acceptability and WTP for digital physiotherapy (P > 0.05).

Conclusion:

In spite of low awareness of digital physiotherapy, Nigerian patients attending physiotherapy clinics are willing to accept and pay for its use irrespective of socio-demographic variations.
