СОЦІАЛЬНІ ВИКЛИКИ ТА ЕТИЧНІ ПРОБЛЕМИ ДИСТАНЦІЙНОГО НАВЧАННЯ В УНІВЕРСИТЕТІ (ПІД ЧАС КАРАНТИНУ COVID-19 В УКРАЇНІ)
Authors: Рогожа М. 
Published: September 2021

Здійснено аналіз зумовлених пандемією та новими соціальними викликами соціально-ціннісних та морально-етичних проблем, зокрема професійного спілкування і дистанційного навчання в університеті під час пандемії COVID-19 і карантину.
Технічні фактори (відсутність безперебійного Інтернет сполучення, комфортного місця для навчання, утрудненість доступу до індивідуальних якісних гаджетів тощо) є свідченням соціальної нерівності та соціальної несправедливості, загострених в умовах карантину та зумовлених рівнем доходів людей та місцем локації (в мешканців великих міст практично відсутня проблема доступу до Інтернету, на відміну від мешканців невеликих міст та проживаючих у сільській місцевості).
Звернуто увагу, що дистанційне навчання редукує особистісний компонент взаємодії викладача зі студентами, сприяючи багатьом негативним моментам у спілкуванні та навчальній діяльності при взаємодії "викладач-студент". У статті визначено, що дистанційна освіта зменшує традиційний для університету особистий компонент спілкування викладача зі студентом як неминучий елемент морального виховання при інкультурації та соціалізації особистості. Чорний екран із вимкненою камерою і мікрофоном сприймається студентом як прояв академічної свободи і незалежності від "електронного синоптикуму" (З. Бауман), але він також звільняє його від відповідальності за інтелектуальну діяльність в аудиторії та не розвиває креативність і належні професійні якості у спілкуванні з викладачем та іншими студентами. Відсутність самодисципліни студента та його / її нездатність організувати особистий навчальний процес за допомогою самопримусу призводять до збільшення розриву між найкращими та найгіршими учнями Нестача самодисципліни здобувача вищої освіти веде до збільшення розриву між сильними і слабкими студентами, коли мова йде про їхні вольові якості, відповідальність та звернення уваги на феномен обов’язку в соціальному бутті, що не сприяє належній соціалізації та інкультурації молоді та ін. Проте указані проблеми стають на заваді отриманню якісної освіти, що становить значний суспільний ризик для українського суспільства.

Starch is one of the food sources that can be extracted from cereals, roots, tubers and stem. Sago palm (metroxylon spp.) is one example of the starch source. The efficiency of the starch extraction process depends on the mechanical properties of process material. This study was conducted to determine the angle of repose between grated sago and kinetic friction of the contact surface between process material and machine. The angle of repose (θ) of grated sago was determined by using a cone shape hopper attached to an adjustable height bar. The cone was filled with a 100g sample of grated sago and slowly adjusted to an upward direction to release the grated sago and will form a conical shape. The cone shape base diameter and height were measured. Next, a square block of debarked sago trunk (8cm × 8cm × 8cm) was placed on a stainless steel plate and attached to a rope at middle connected to force gauges. The pulling speed was at 1.27 mm/min and the result of total pulling load (F) was recorded. The process was repeated for materials with different moisture content (MC) of 60%, 50%, 40%, and 30%. Based on the experimental results, the angle of repose (AoR= 47.000±0.31) and coefficient of kinetic friction (μ k) 0.88±0.005 at MC= 60% showed decrease in value (AoR= 43.610±0.34; μ k = 0.83±0.002) when the MC decrease by 30% (P<0.01).
Serendipisyyskokemuksia asiantuntijatyössä
Authors: Toivanen Minna , Känsälä Marja , Kalliomäki-Levanto Tiina 
Published: September 2021

Työssä voi kohdata monenlaisia yhteensattumia. Toisinaan nuo sattumukset ovat todellisia onnenpotkuja, toisinaan niiden merkitys on pienempi, mutta ne voivat silti olla hyödyllisiä tai merkityksellisiä. Nämä onnekkaat sattumat eli sattumalöydökset ovat serendipisyyskokemuksia. Tämän tutkimuksen tavoitteena on selvittää 1) millaisia sattumanvaraisia havaintoja asiantuntija­ työssä kohdataan, 2) missä sattumanvaraisia havaintoja tehdään, 3) missä määrin nämä havainnot tapahtuvat digitaalisessa ympäristössä ja 4) millaisia arvokkaita asioita syntyy sattuman seurauksena. Tutkimuksen teoreettisena viitekehyksenä toimii serendipisyyteen kohdistuva tutkimustraditio. Tutkimus pohjautuu kolmentyyppiseen keväällä 2019 kerättyyn laadulliseen aineistoon: haastattelut, työpaja­aineisto ja kyselyn avovastaukset. Kaikkiaan aineistoista tunnistettiin 437 sattumaesimerkkiä. Sosiaalinen vuorovaikutus ja ihmisten kasvokkainen kohtaaminen omalla työpaikalla osoittautuivat keskeisimmiksi serendipisyyskokemusten paikoiksi asiantuntijatyössä. Onnekkaitten löytöjen kautta syntyi sekä pieniä oivalluksia omaan työhön, kuten ohjelman tai sovelluksen uusia käyttötapoja, että merkittäviä tiedettä tai oman työpaikan toimintaa edistäviä havaintoja tai ratkaisuja. Tutkimus osoitti, että serendipisyys ei ole harvinainen ilmiö vaan ennemminkin luonnollinen ja olennainen osa asiantuntijatyötä.
The Solar System as an Exosystem: Planet Confusion
Authors: Keithly Dean Robert , Savransky Dmitry 
Published: September 2021

Abstract
Future, large-scale, exoplanet direct-imaging missions will be capable of discovering and characterizing Earth-like exoplanets and star systems like our solar system. However, a telescope capable of detecting Earth-like exoplanets would also be sensitive to a myriad of non-Earth-like exoplanets in the exoplanet population with the same instantaneous planet–star separation (s) and planet–star difference in magnitude (Δmag). Here, we consider the solar system as a previously unexplored exosystem, viewed by an external direct-imaging observer for the first time. We find that an external observer could see as many as six (s, Δmag)-coincidence locations between the Earth and other solar system planets. We determine locations of (s, Δmag)-coincidence of solar system planets using realistic planet phase functions and planet properties. By varying system inclinations, we found 36%–69% of inner planet orbits and 1%–4% of outer planet orbits share at least one (s, Δmag)-coincidence with the Earth.
Collision Chains among the Terrestrial Planets. III. Formation of the Moon
Authors: Asphaug Erik , Emsenhuber Alexandre , Cambioni Saverio , Gabriel Travis S. J. , Schwartz Stephen R. 
Published: September 2021

Abstract
In the canonical model of Moon formation, a Mars-sized protoplanet “Theia” collides with proto-Earth at close to their mutual escape velocity v
esc and a common impact angle ∼45°. The “graze-and-merge” collision strands a fraction of Theia’s mantle into orbit, while Earth accretes most of Theia and its momentum. Simulations show that this produces a hot, high angular momentum, silicate-dominated protolunar system, in substantial agreement with lunar geology, geochemistry, and dynamics. However, a Moon that derives mostly from Theia’s mantle, as angular momentum dictates, is challenged by the fact that O, Ti, Cr, radiogenic W, and other elements are indistinguishable in Earth and lunar rocks. Moreover, the model requires an improbably low initial velocity. Here we develop a scenario for Moon formation that begins with a somewhat faster collision, when proto-Theia impacts proto-Earth at ∼ 1.2v
esc, also around ∼45°. Instead of merging, the bodies come into violent contact for a half hour and their major components escape, a “hit-and-run” collision. N-body evolutions show that the “runner” often returns ∼0.1–1 Myr later for a second giant impact, closer to v
esc; this produces a postimpact disk of ∼2–3 lunar masses in smoothed particle hydrodynamics simulations, with angular momentum comparable to canonical scenarios. The disk ends up substantially inclined, in most cases, because the terminal collision is randomly oriented to the first. Moreover, proto-Earth contributions to the protolunar disk are enhanced by the compounded mixing and greater energy of a collision chain.
Multiple Moist Climate Equilibrium States on Arid Rocky M-dwarf Planets: A Last-saturation Tracer Analysis
Authors: Ding Feng , Wordsworth Robin D. 
Published: September 2021

Abstract
Terrestrial-type exoplanets orbiting nearby red dwarf stars (M dwarfs) are the first potentially habitable exoplanets suitable for atmospheric characterization in the near future. Understanding the stability of water in cold-trap regions on such planets is critical because it directly impacts transmission spectroscopy observations, the global energy budget, and long-term surface water evolution. Here we diagnose the humidity distribution in idealized general circulation model simulations of terrestrial-type exoplanets. We use the “tracer of last saturation” technique to study the saturation statistics of air parcels. We find that on synchronously rotating planets the water vapor abundance in the nightside upper troposphere depends weakly on planetary rotation, while more water vapor builds up in the nightside lower troposphere on fast-rotating planets. We then discuss how last-saturation statistics can elucidate the multiple moist climate equilibrium states on synchronously and asynchronously rotating arid planets. We show that the multiple moist climate states arise from the cold-trapping competition between the substellar upper atmosphere and cold surface regions. We find that fast synchronously rotating planets tend to trap surface water on the nightside as a result of their weak atmospheric and strong surface cold traps compared to the slow-rotating case. These results elucidate the nature of the water cycle on arid rocky exoplanets and will aid interpretation of atmospheric observations in the future.
La séparation des compétences techniques et non techniques à l’épreuve de l’analyse interactionnelle du travail simulé en santé
Authors: Tisserand Lucien 
Published: September 2021

Les pratiques de simulation clinique pleine échelle en santé ont pour objet l’enseignement d’une pratique réflexive sur ses propres techniques communicatives et organisationnelles. Pour ce faire, les participant·e·s désignent les pratiques attendues et les pratiques à éviter en tant que compétences « non techniques », soit des compétences non spécifiques à la profession, désignées séparément par des référentiels de notions mobilisées pendant le débriefing. Dans cet article, nous expliquons comment l’analyse conversationnelle multimodale peut documenter l’émergence d’un problème organisationnel désigné par les membres eux-mêmes lors de la simulation. Ce faisant, nous répondons à leur intérêt pour l’organisation du travail autour du patient en permettant aux professionnel·le·s de disposer de ressources construites de manière ancrée dans l’analyse de leur travail tel qu’il est effectué. On voit ainsi les compétences organisationnelles comme situées irrémédiablement dans les pratiques plutôt que des compétences « non techniques ».
Les politiques d’adaptation de l’habitat des seniors en France et en Allemagne
Authors: André Viviane , Ille-Roussel Marion 
Published: September 2021

La France et l’Allemagne, engagées pour le maintien à domicile, mettent en place des aides financières pour adapter le parc de logement au vieillissement et à la perte d’autonomie. L’analyse de ces instruments de l’action publique démontre que le regard porté sur la dépendance et la vieillesse diffère entre les deux pays. La prise en compte du besoin de soins par la Pflegeversicherung (assurance soins) en Allemagne fait de l’adaptation du logement un droit universel, indépendamment de l’âge et du niveau de revenu. En France, l’État et les départements suivent à l’inverse une logique de « séniorisation » face à la perte d’autonomie. Les Länder allemands complètent des aides de l’État pour rendre l’investissement et l’amélioration du parc bâti plus accessible, favorisant une approche préventive de la dépendance pour des logements adaptés à tous les âges de la vie et aux besoins des territoires. Cette approche territoriale se retrouve en partie en France par l’intervention des collectivités locales dans le cadre d’opérations programmées d’amélioration de l’habitat (OPAH) mises en place avec l’agence nationale de l’habitat (ANAH), ou de programmes propres.
Controllability and stabilization of gravity-capillary surface water waves in a basin
Authors: Cui Jing , Gao Guangyue , Sun Shu-Ming 
Published: September 2021

<p style='text-indent:20px;'>The paper concerns the controllability and stabilization of surface water waves in a two-dimensional rectangular basin under the forces of gravity and surface tension. The surface waves are generated by a wave-maker placed at the left side-boundary and it is physical relevant to see whether the surface waves are controllable or can be stabilized using appropriate motion of the wave-maker. Due to the surface tension, an edge condition must be imposed at the contact point between the free surface and a solid boundary. Two types of wave-makers are considered: "flexible" or "rigid". It is shown that the surface waves are approximately controllable, but not exactly controllable, for both "flexible" and "rigid" wave-makers. In addition, under a static feedback to control a "rigid" wave-maker, the strong stability of feedback control system is obtained.</p><p style='text-indent:20px;'> </p><p style='text-indent:20px;'>Correction: The page numbers on each page of the PDF file have been corrected.

Exploring the Interaction between E484K and N501Y Substitutions of SARS-CoV-2 in Shaping the Transmission Advantage of COVID-19 in Brazil: A Modeling Study
Authors: Zhao Shi , Ran Jinjun , Han Lefei 
Published: September 2021

ABSTRACT.
The COVID-19 pandemic poses serious threats to global health, and the emerging mutation in SARS-CoV-2 genomes is one of the major challenges of disease control. Considering the growth of epidemic curve and the circulating SARS-CoV-2 variants in Brazil, the role of locally prevalent E484K and N501Y substitutions in contributing to the epidemiological outcomes is of public health interest for investigation. We developed a likelihood-based statistical framework to reconstruct reproduction numbers, estimate transmission advantage associated with different SARS-CoV-2 variants regarding the marking (identifying) 484K and 501Y substitutions (including Alpha, Zeta, and Gamma variants) in Brazil, and explored the interactive effects of genetic activities on transmission advantage marked by these two mutations. We found a significant transmission advantage associated with the 484K/501Y variants (including P.1 or Gamma variants), which increased the infectivity significantly by 23%. In contrast and by comparison to Gamma variants, E484K or N501Y (including Alpha or Zeta variants) substitution alone appeared less likely to secure a concrete transmission advantage in Brazil. Our finding indicates that the combined impact of genetic activities on transmission advantage marked by 484K/501Y outperforms their independent contributions in Brazil, which implies an interactive effect in shaping the increase in the infectivity of COVID-19. Future studies are needed to investigate the mechanisms of how E484K and N501Y mutations and the complex genetic mutation activities marked by them in SARS-CoV-2 affect the transmissibility of COVID-19.

ABSTRACT.
It is essential to examine the longevity of the defensive immune response engendered by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. We examined the SARS-CoV-2-specific antibody responses and ex vivo memory B-cell subsets in seven groups of individuals with COVID-19 classified based on days since reverse-transcription polymerase chain reaction confirmation of SARS-CoV-2 infection. Our data showed that the levels of IgG and neutralizing antibodies started increasing from days 15 to 30 to days 61 to 90, and plateaued thereafter. The frequencies of naive B cells and atypical memory B cells decreased from days 15 to 30 to days 61 to 90, and plateaued thereafter. In contrast, the frequencies of immature B cells, classical memory B cells, activated memory B cells, and plasma cells increased from days 15 to 30 to days 61 to 90, and plateaued thereafter. Patients with severe COVID-19 exhibited increased frequencies of naive cells, atypical memory B cells, and activated memory B cells, and lower frequencies of immature B cells, central memory B cells, and plasma cells when compared with patients with mild COVID-19. Therefore, our data suggest modifications in memory B-cell subset frequencies and persistence of humoral immunity in convalescent individuals with COVID-19.
