description: The torques exerted by a locally isothermal disk on an embedded planet lead to rapid inward migration. Recent work has shown that modeling the thermodynamics without the assumption of local isothermality reveals regions where the net torque on an embedded planet is positive, leading to outward migration of the planet. When a region with negative torque lies directly exterior to this, planets in the inner region migrate outwards and planets in the outer region migrate inwards, converging where the torque is zero. We incorporate the torques from an evolving non-isothermal disk into an N-body simulation to examine the behavior of planets or planetary embryos interacting in the convergence zone. We find that mutual interactions do not eject objects from the convergence zone. Small numbers of objects in a laminar disk settle into near resonant orbits that remain stable over the 10 Myr periods that we examine. However, either or both increasing the number of planets or including a correlated, stochastic force to represent turbulence drives orbit crossings and mergers in the convergence zone. These processes can build gas giant cores with masses of order ten Earth masses from sub-Earth mass embryos in 2-3 Myr.

description: While conventional interior models for Jupiter and Saturn are based on the simplistic assumption of a solid core surrounded by a homogeneous gaseous envelope, we derive new models with an inhomogeneous distribution of heavy elements, i.e. a gradient of composition, within these planets. Such a compositional stratification hampers large scale convection which turns into double-diffusive convection, yielding an inner thermal profile which departs from the traditionally assumed adiabatic interior, affecting these planet heat content and cooling history. To address this problem, we develop an analytical approach of layered double-diffusive convection and apply this formalism to Solar System gaseous giant planet interiors. These models satisfy all observational constraints and yield a metal enrichment for our gaseous giants up to 30 to 60% larger than previously thought. The models also constrain the size of the convective layers within the planets. As the heavy elements tend to be redistributed within the gaseous envelope, the models predict smaller than usual central cores inside Saturn and Jupiter, with possibly no core for this latter. These models open a new window and raise new challenges on our understanding of the internal structure of giant (solar and extrasolar) planets, in particular on the determination of their heavy material content, a key diagnostic for planet formation theories.

description: Leclerc and Zelevinsky described quasicommuting families of quantum minors in terms of a certain combinatorial condition, called weak separation. They conjectured that all maximal by inclusion weakly separated collections of minors have the same cardinality, and that they can be related to each other by a sequence of mutations. On the other hand, Postnikov studied total positivity on the Grassmannian. He described a stratification of the totally nonnegative Grassmannian into positroid strata, and constructed their parametrization using plabic graphs. In this paper we link the study of weak separation to plabeic graphs. We extend the notion of weak separation to positroids. We generalize the conjectures of Leclerc and Zelevinsky, and related ones of Scott, and prove them. We show that the maximal weakly separated collections in a positroid are in bijective correspondence with the plabic graphs. This correspondence allows us to use the combinatorial techniques of positroids and plabic graphs to prove the (generalized) purity and mutation connectedness conjectures.

description: Abstract: The training of adolescents in health promotion has become a global interest. The creation of future human beings capable of preserving health, the human species and the planet, is the desire and duty of current generations. The Covid-19 pandemic unleashed questions regarding the responsibilities of man as a species and health systems throughout the world. In order to characterize the comprehensive training of adolescents in health promotion in Cuba today, the subject of the current study was systematized based on current research, as well as pedagogical, psychological and social references. For this, theoretical qualitative methods were used such as logical historical, hermeneutic, and synthesis analysis. Description and bibliographic review were also used. Educational actions were proposed herein for the training of adolescents in health promotion during the Covid-19 pandemic. There were the use of ICTs that promote the empowerment and resilience of secondary school students to achieve human development and commitment to community, health, and environment.
On the properties of the Volkov solutions of the Klein-Gordon equation

description: We present an elementary proof based on a direct calculation of the property of completeness at constant time of the solutions of the Klein-Gordon equation for a charged particle in a plane wave electromagnetic field. We also review different forms of the orthogonality and completeness relations previously presented in the literature and we discuss the possibility to construct the Feynman propagator for the particle in a plane-wave laser pulse as an expansion in terms of Volkov solutions. We show that this leads to a rigorous justification for the expression of the transition amplitude, currently used in the literature, for a class of laser assisted or laser induced processes.

description: This paper studies cluster algebras locally, by identifying a special class of localizations which are themselves cluster algebras. A `locally acyclic cluster algebra' is a cluster algebra which admits a finite cover (in a geometric sense) by acyclic cluster algebras. Many important results about acyclic cluster algebras extend to local acyclic cluster algebras (such as finite generation, integrally closure, and equaling their upper cluster algebra), as well as results which are new even for acyclic cluster algebras (such as regularity when the exchange matrix has full rank). We develop several techniques for determining whether a cluster algebra is locally acyclic. We show that cluster algebras of marked surfaces with at least two boundary marked points are locally acyclic, providing a large class of examples of cluster algebras which are locally acyclic but not acyclic. We also work out several specific examples in detail.

Проблему интенсификации теплообмена в трубах при умеренном росте перепада давления можно решать созданием псевдоожижения твердых частиц в восходящем потоке основного теплоносителя. Интенсивность переноса тепла в псевдоожиженном слое значительно выше, чем в однофазном газовом потоке в пустой трубе или в заполненной неподвижным зернистым материалом.
description: The results of experimental studies on the hydrodynamics of the fluidized bed are presented. The problem of intensification of heat exchange in pipes with a moderate increase in pressure drop can be solved by creating fluidization of solid particles in the upstream of the main coolant. The intensity of heat transfer in a fluidized bed is significantly higher than in a single-phase gas flow in an empty pipe or in a pipe filled with a stationary granular material.

description: In der wissenschaftlichen Literatur zum Innovationsmanagement – wie in der betrieblichen Praxis der Neuproduktentwicklung – wird der Einsatz von „innovativen Analogien“ als ein vielversprechender Ansatz gesehen, denn hierdurch kann bereits bestehendes Wissen zur Lösung von Problemstellungen, die in anderen Kontexten situiert sind, eingesetzt werden. Innovative Analogien können somit maßgeblich zur Reduzierung von Technologie- und Marktrisiken beitragen. Insbesondere die Senkung der Entwicklungskosten sowie –risiken lässt den Einsatz von innovativen Analogien auch bei der Entwicklung von sog. „frugalen“, kostengünstigen und effizienzorientierten, Innovationen, als attraktiv erscheinen. Dieser Zusammenhang ist bisher in der wissenschaftlichen Literatur nicht explizit aufgegriffen worden. In dem vorliegenden Beitrag untersuchen wir einige operationale Aspekte frugaler Produktentwicklung anhand ausgewählter Fallstudien aus Indien und können feststellen, dass gerade frugale Innovationen besonders häufig auf innovative Produktanalogien zurückgreifen. Der Analogieeinsatz bei frugalen Innovationen beinhaltet darüber hinaus auch einige, wichtige Erkenntnisse für die Analogieforschung: (1) Der Einsatz von innovativen Analogien ist nicht unbedingt auf die frühen Innovationsphasen beschränkt; er kann vielmehr alle Phasen des Innovationsprozesses durchdringen, und (2) Die funktionale Fixierung und übermäßiger Verlass auf lokales Wissen ist in frugalen Innovationsprojekten weniger verbreitet und die Akzeptanz externen Wissens deutlich größer. Diese Erkenntnis liefert nützliche Rückschlüsse für die Produktentwicklungsprozesse auch im nicht-frugalen Bereich.
description: Use of innovative analogies is seen as a promising instrument for systematizing innovation processes in firms, for it allows transferring of existing knowledge and technologies from one knowledge/industrial domain to the other and thus helps in creating new and cost-effective solutions. Their use in developing affordable and efficiency-oriented "frugal innovations" has so far not been researched in the academic works. This conceptual paper based on three explorative case studies from India examines use of innovative analogies in creating frugal solutions and comes to the conclusion that analogies, by the virtue of reducing market and technology risks, have the potential of causing a significantly positive impact on innovations in a resource-constrained environment and targeted at price-sensitive customers. Beyond that, there seems to be a noteworthy scope for learnings in regards to effectively employing analogies that can be transferred from the frugal to the non-frugal context.
Comprehensibility assessment : the influence of familiar and unfamiliar partners

Publisher: name: University of British Columbia

description: For many years, the primary focus of assessment and intervention in the field of dysarthria rehabilitation has been the speech output of the affected speaker, as measured by intelligibility. However, this narrow focus on the acoustic adequacy of the speech signal falls short of capturing the full spectrum of information available to speakers and their partners during naturalistic interaction. Alternatively, comprehensibility measures acknowledge that everyday communicative success is greatly affected by the presence of multiple types of signal-independent information (e.g., visual cues, listener familiarity), as well as the dynamics of dyadic interaction (e.g., breakdown repair strategies). In this way, comprehensibility measures may more functionally assess dysarthria severity and the extent to which persons with dysarthria experience disability. The goals of the present study were to establish evidence for the reliability of a structured assessment of comprehensibility for dysarthric speech (developed by Visser, 2004), to investigate how the assessment reflected the effects of listener familiarity on communicative success, and to investigate how strategy use may differ under different familiarity conditions. Two speakers with dysarthria secondary to primary lateral sclerosis (PLS) were each paired with two communication partners: one familiar partner and one unfamiliar partner, to form four dyads in total. Each of these partners scored the speaker’s intelligibility and participated in a dyad-based structured assessment of comprehensibility with the speaker. Results indicated that the assessment was scored with an extremely high degree of inter- and intra-rater reliability. In addition, comprehensibility scores were substantially better for both speakers with familiar versus unfamiliar partners, whereas substantial differences in intelligibility scores were noted for only one speaker. As predicted, unfamiliar dyads were found to use more strategies than familiar dyads, with some overlap across dyads in terms of the strategies used. Overall, the structured assessment of comprehensibility reliably differentiated familiar from unfamiliar dyads, suggesting it may be a clinically relevant assessment tool.

description: RX J0720.4-3125 is the most peculiar object among a group of seven isolated X-ray pulsars (the so-called "Magnificent Seven"), since it shows long-term variations of its spectral and temporal properties on time scales of years. This behaviour was explained by different authors either by free precession (with a seven or fourteen years period) or possibly a glitch that occurred around $\mathrm{MJD=52866\pm73 days}$. We analysed our most recent XMM-Newton and Chandra observations in order to further monitor the behaviour of this neutron star. With the new data sets, the timing behaviour of RX J0720.4-3125 suggests a single (sudden) event (e.g. a glitch) rather than a cyclic pattern as expected by free precession. The spectral parameters changed significantly around the proposed glitch time, but more gradual variations occurred already before the (putative) event. Since $\mathrm{MJD\approx53000 days}$ the spectra indicate a very slow cooling by $\sim$2 eV over 7 years.

description: Abstract: According to the Cultural-Historical Activity approach, the main source of a child's psychological development is meaningful communication, which revolves around some problem matter. Diagnostic means should thus strive to assess whether this communication is productive, especially in the context of the digitalization of education. The purpose of this study was to test an approach to the assessment design based on Davydov's theory of learning activity, which emphasizes the crucial role of joint actions. We have developed a computer game, which emulates joint solving of a logic task, while distributing the essential operations between students. The "Labyrinth" task challenges students to discover a general rule, following which the sequence of keys should be chosen to pass through all dungeon cells successfully. The twist of the task was used earlier to evaluate students' metacognitive competencies, which gives us the opportunity to compare the results of joint solving to individual performance. In the current procedure, students must coordinate their actions, as the computer 22 simulation does not allow them to make any "step" through the labyrinth without cooperation. We conducted pilot experiments with pairs of students (8 -12 years old) to test the procedure, and we repeatedly adjusted the procedure to prompt joint actions in the inquiry-based problem. Digital records of students' routes and video-taped discussions were used as data-source. The results show that the successful accomplishment of the labyrinth challenge (i.e., the identification of the general rule) significantly depended on the meaningfulness of the students' communication. The thoughtful inquiry-based learning activity thus opposes common trial and error method, which proves to be insufficient. The digital means, which scaffold joint actions, contribute significantly here.

description: В данной статье авторами приведен экапериментальные исследование гидродинамики, структуры и внешнего теплообмена полидисперсного зернистого материала, состоящего из частиц неправильной формы частиц. Отмечено, одним из наиболее перспективных методов интенсификации теплообмена является использование в качестве промежуточного теплоносителя псевдоожиженного слоя твердого зернистого материала. Интенсивность переноса тепла в псевдоожиженных системах зависит от гидродинамики и структуры слоя, также гидравлическое сопротивление неподвижного и взвешенного слоев полидисперсного зернистого материала. Организация псевдоожижения твердых частиц полидисперсного зернистого материала в теплообменном аппарате позволяет существенно интенсифицировать теплоперенос, вследствие разрушения и турбулизации пристенного слоя жидкостного потока.В инженерной практике особенно важно уметь заранее оценить скорость (расход) жидкости, необходимый для перевода неподвижного слоя частиц различного диаметра в псевдоожиженное состояние.
description: In this article, the authors present an experimental study of the hydrodynamics, structure and external heat transfer of a polydisperse granular material consisting of irregularly shaped particles. It is noted that one of the most promising methods of heat exchange intensification is the use of a fluidized bed of solid granular material as an intermediate coolant. The intensity of heat transfer in fluidized systems depends on the hydrodynamics and structure of the layer, as well as the hydraulic resistance of stationary and suspended layers of polydisperse granular material. The organization of fluidization of solid particles of polydisperse granular material in a heat exchanger makes it possible to significantly intensify heat transfer, due to the destruction and turbulence of the wall layer of the liquid flow.In engineering practice, it is especially important to be able to estimate in advance the velocity (flow rate) of the liquid required to transfer a stationary layer of particles of various diameters to a fluidized state.

description: In the 1960s, Tanzanian student Erasto Mpemba and his teacher published an article with the title "Cool" in the journal Physics Education (Mpemba, E. B. - Osborne, D. G.: Cool?. In: Physics Education, vol.4, 1969, pp. 172-175.). In this article they claimed that hot water freezes faster than cold water. The article raised not only a wave of discussions, and other articles about this topic, but also a whole series of new experiments, which should verify this apparent thermodynamic absurdity and find an adequate explanation. Here we give a review with references to explanations and we bring some proposals for experimental student work in this area. We introduce Mpemba Effect not only as a paradoxical physics phenomenon, but we shall present a strong educational message that the Mpemba story brings to the teachers and their students. This message also creates a bridge between this phenomenon and the discovery for which the 2011 Nobel Prize in Chemistry was awarded. It leads to critical adoption of traditional knowledge and encourages resilience in investigative exploration of new things.

description: Abstract: Two new phrases have recently appeared in the discourse of child psychology: “screen time” and “green time”. The concept illuminates two realities – the time being spent in front of the screen of the gadget and the time outside of it. This raises the question of how “screen time” influences a child’s behavior and their self-regulation during the interaction with cultural rules. A child’s gadget passion may provoke plenty of problems. Research goal. It was hypothesized that “screen time” affects children’s behavior. The common assumption is that children that frequently use smartphones don’t obey adults and don’t do their homework, illustrating a transformation in the habitual behavioral patterns of the children. The sample and the methodology. 200 children (average age = 8.6 ± 0.2) participated in the study. The time children spent with the gadget was measured, the “screen time” was calculated as the average time being spent during a week. The behavioral patterns were explored by the cultural congruence methodology. This methodology allowed us to diagnose the compliance of the child’s behavior to the cultural rules typical for his age. These rules are summarized in five factors: “Social interaction”, “Learning competence”, “Self-control”, “Obedience”, “Self-service”, and “Reglementation.” Results. Interestingly, the study distinguished three groups of children: 1) those who attend a musical school, 2) those who are engaged in artistic activities, and 3) those who are not engaged in any system of additional education. Art-based activities allowed the children to have a chance to increase the “green time” away from the screen. The study confirmed that the average screen time in the 3rd group of children was higher. The screen time was statistically connected to the level of cultural congruence i.e., the compliance of the child’s behavior to the cultural norms typical for his age. Conclusion. Indicators of the maturity of behavior patterns according to the cultural norms typical for a given age are higher among children engaged in musical and artistic activities. These results prove that the children who devote their “green time” to art assimilate to the rules better. This is the mark of successful socialization, as far as the interaction of a child takes place in a normative situation where the rules exist

description: We present a method for the evaluation of the interaction potential of an equilibrium classical system starting from the (partial) knowledge of its structure factor. The procedure is divided into two phases both of which are based on the maximum entropy principle of information theory. First we determine the maximum entropy estimate of the radial distribution function constrained by the information contained in the structure factor. Next we invert the pair function and extract the interaction potential. The method is tested on a Lennard-Jones fluid at high density and the reliability of its results with respect to the missing information in the structure factor data are discussed. Finally, it is applied to the experimental data of liquid sodium at 100$^{\circ}$C.

description: Abstract: During the COVID-19 pandemic, there was an increase in the use of information technologies by teachers. These changes affected the duration, automation, communication, and object of labor. The purpose of this study was to assess the change in the professional environment of teachers. Research methods: conversation and self-developed questionnaires. Sampling: teachers using Moodle and Zoom systems. The main results: there was a change in the perception of the object of labor when using Zoom and Moodle and the duration and satisfaction with work due to technical errors of the systems during use. The role of the teacher has also changed. They must not only be a teacher, but simultaneously an operator of an automated information system, the successful use of which requires additional preparation. Conclusion: during the study it was revealed, firstly, that the teacher plays the role of an automated system operator, which requires additional training and optimization of the system interface, where interface and user errors were identified and classified. The identified errors led to disruption of communications within the system and the duration of work, causing work dissatisfaction. Adaptation of the system would partially automate the work of the teacher and save time. Secondly, to increase satisfaction with the use of video systems, it is required to establish mandatory rules for the conduction remote classes e.g. turning on cameras and microphones. This is because the object of labor is changing visually the student may be in class, but they do not physically participate in the process

description: The highly advanced treatment of surfaces as etching and deposition is mainly enabled by the extraordinary properties of technological plasmas. The primary factors that influence these processes are the flux and the energy of various species, particularly ions, that impinge the substrate surface. These features can be theoretically described using the ion energy distribution function (IEDF). The article is intended to summarize the fundamental concepts of modeling and simulation of IEDFs from simplified models to self-consistent plasma simulations.

post-Soviet Russia
changes in norms

description: collapse of the Soviet system. In the 1990s, many mothers were already starting to receive the message from society that was along the lines of: “Only you need your child” (Isupova 2000). Back in the 1980s, at least at the level of official representations, birth and the upbringing of children was understood as the main duty of a woman to the state and society. Accordingly, women could count on the help of the state and society along this path. For example, nurseries and kindergartens were available for young children, although not accessible to everyone. It was customary to ask for help in maternal work and even demand it. Since then, motherhood has become an increasingly solitary experience and an area of individual duty. The ideas of intensive motherhood (Hays, 1996) came to Russia a little later than in the most developed countries, then becoming very influential in a modern society where individualistic values came to dominate. The peak of popularity of this approach among urban Russian women came in the 2000s, after which families as a whole became poorer, and women working as a means of earning became more desirable. At the same time, a different, conservative reaction began to openly proclaim the main responsibility of a woman as living within the family and taking care of other family members. Thus, intensive motherhood in Russia in recent years has existed not in its happier and sometimes freely chosen form, but as a burden, since the need to combine work, motherhood and domestic duties is now felt by many as an even harder life than that led by their Soviet grandmothers. The requirements of a mother then and now are different, but it is difficult to judge in which era the situation was more difficult. 25 The article is based on a qualitative textual analysis of the current situation using the Vkontakte public “Happiness of motherhood”, where modern mothers from Russia discuss with each other the practical and emotional problems associated with their parenthood.

description: Despite over a decade of intense research efforts, the full potential of two-dimensional transition metal dichalcogenides continues to be limited by major challenges. The lack of compatible and scalable dielectric materials and integration techniques restrict device performances and their commercial applications Conventional dielectric integration techniques for bulk semiconductors are difficult to adapt for atomically thin two-dimensional materials. This review provides a brief introduction into various common and emerging dielectric synthesis and integration techniques and discusses their applicability for 2D transition metal dichalcogenides. Dielectric integration for various applications is reviewed in subsequent sections including nanoelectronics, optoelectronics, flexible electronics, valleytronics, biosensing, quantum information processing, and quantum sensing. For each application, we introduce basic device working principles, discuss the specific dielectric requirements, review current progress, present key challenges, and offer insights into future prospects and opportunities.

description: Abstract: Relevance. The rapid spread of modern information technologies and the transition to distance learning during the COVID 19 pandemic has led to an increase in parents' anxiety about adolescents' low communication skills in real life. At the same time, parents fail to see the positive aspects of the virtual world. Accordingly, virtual reality has become an object of conflict and subject of family counseling. The purpose of this study is to highlight the strategy of the counselor when dealing with families with adolescents. Research methods and sample. Case-study analysis of 14 families with adolescents 14 -16 years old during the pandemic (2020-2022), a survey of parents of adolescents (43 people in total). Main results. Adolescents were characterized as introverts, sensitive, quick to get tired, experience difficulties in communicating with peers, and intellectually developed. For this category of teenagers, the transition to distance learning was a positive that allowed them to study at their own pace and improve academic performance, which was also noted by parents. This circumstance was used by the counselor as a starting point for changing the attitude of parents to the internet. The content of the consultation also included relationships, behavior in conflict situations, attitudes towards success and failure. Interest in computer games and virtual life is most often unexpected for teenagers. It helps to establish contact with a psychologist, opens a new world for parents, and promotes an open discussion of the dangers of the internet. Conclusion. Accordingly, the task of the counselor was to expand the parents' understanding of the possibilities of modern technology, reduce their anxiety and, ultimately, promote acceptance of their children. It is this position that contributes to the differentiation between virtual and real life by adolescents, the growth of their self-control.
Comment on "Charge-parity symmetry observed through Friedel oscillations in chiral charge-density waves" by J. Ishioka et al

description: In their publication [Phys. Rev B, 84, 245125 (2011)], Ishioka et al. discuss the recently discovered chiral charge density wave state in 1T-TiSe2 in terms of a parameter H_CDW, whose sign is suggested to correspond to the handedness of the chiral order. Here we point out that H_CDW, as defined by Ishioka et al., cannot be used to characterize chirality in that way. An alternative measure of chirality for the specific case of 1T-TiSe2 is suggested.

On the connection between the magneto-elliptic and magneto-rotational instabilities

description: It has been recently suggested that the magneto-rotational instability (MRI) is a limiting case of the magneto-elliptic instability (MEI). This limit is obtained for horizontal modes in the presence of rotation and an external vertical magnetic field, when the aspect ratio of the elliptic streamlines tends to infinite. In this paper we unveil the link between these previously unconnected mechanisms, explaining both the MEI and the MRI as different manifestations of the same Magneto-Elliptic-Rotational Instability (MERI). The growth rates are found and the influence of the magnetic and rotational effects is explained, in particular the effect of the magnetic field on the range of negative Rossby numbers at which the horizontal instability is excited. Furthermore, we show how the horizontal rotational MEI in the rotating shear flow limit links to the MRI by the use of the local shearing box model, typically used in the study of accretion discs. In such limit the growth rates of the two instability types coincide for any power-type background angular velocity radial profile with negative exponent corresponding to the value of the Rossby number of the rotating shear flow. The MRI requirement for instability is that the background angular velocity profile is a decreasing function of the distance from the centre of the disk which corresponds to the horizontal rotational MEI requirement of negative Rossby numbers. Finally a physical interpretation of the horizontal instability, based on a balance between the strain, the Lorentz force and the Coriolis force is given.
