Atopic dermatitis is accompanied by the abnormal overgrowth of Staphylococcus aureus, a common cause of skin infections and an opportunistic pathogen. Although administration of antibiotics is effective against S. aureus, the resulting reduction in healthy microbiota and the emergence of drug-resistant bacteria are of concern. We propose that phage therapy can be an effective strategy to treat atopic dermatitis without perturbing the microbiota structure. In this study, we examined whether the S. aureus phage SaGU1 could be a tool to counteract the atopic exacerbation induced by S. aureus using an atopic mouse model. Administration of SaGU1 to the back skin of mice reduced both S. aureus counts and the disease exacerbation caused by S. aureus. Furthermore, the S. aureus-mediated exacerbation of atopic dermatitis with respect to IgE plasma concentration and histopathological findings was ameliorated by the application of SaGU1. We also found that Staphylococcus epidermidis, a typical epidermal symbiont in healthy skin, significantly attenuated the emergence of SaGU1-resistant S. aureus under co-culture with S. aureus and S. epidermidis in liquid culture infection experiments. Our results suggest that phage therapy using SaGU1 could be a promising clinical treatment for atopic dermatitis.
Structure and Hierarchy of SARS-CoV-2 Infection Dynamics Models Revealed by Reaction Network Analysis
Authors: Peter Stephan , Dittrich Peter , Ibrahim Bashar
Published: December 2020

This work provides a mathematical technique for analyzing and comparing infection dynamics models with respect to their potential long-term behavior, resulting in a hierarchy integrating all models. We apply our technique to coupled ordinary and partial differential equation models of SARS-CoV-2 infection dynamics operating on different scales, that is, within a single organism and between several hosts. The structure of a model is assessed by the theory of chemical organizations, not requiring quantitative kinetic information. We present the Hasse diagrams of organizations for the twelve virus models analyzed within this study. For comparing models, each organization is characterized by the types of species it contains. For this, each species is mapped to one out of four types, representing uninfected, infected, immune system, and bacterial species, respectively. Subsequently, we can integrate these results with those of our former work on Influenza-A virus resulting in a single joint hierarchy of 24 models. It appears that the SARS-CoV-2 models are simpler with respect to their long term behavior and thus display a simpler hierarchy with little dependencies compared to the Influenza-A models. Our results can support further development towards more complex SARS-CoV-2 models targeting the higher levels of the hierarchy.
Advances in Oral Subunit Vaccine Design
Authors: Van der Weken Hans , Cox Eric , Devriendt Bert
Published: December 2020

Many pathogens invade the host at the intestinal surface. To protect against these enteropathogens, the induction of intestinal secretory IgA (SIgA) responses is paramount. While systemic vaccination provides strong systemic immune responses, oral vaccination is the most efficient way to trigger protective SIgA responses. However, the development of oral vaccines, especially oral subunit vaccines, is challenging due to mechanisms inherent to the gut. Oral vaccines need to survive the harsh environment in the gastrointestinal tract, characterized by low pH and intestinal proteases and need to reach the gut-associated lymphoid tissues, which are protected by chemical and physical barriers that prevent efficient uptake. Furthermore, they need to surmount default tolerogenic responses present in the gut, resulting in suppression of immunity or tolerance. Several strategies have been developed to tackle these hurdles, such as delivery systems that protect vaccine antigens from degradation, strong mucosal adjuvants that induce robust immune responses and targeting approaches that aim to selectively deliver vaccine antigens towards specific immune cell populations. In this review, we discuss recent advances in oral vaccine design to enable the induction of robust gut immunity and highlight that the development of next generation oral subunit vaccines will require approaches that combines these solutions.

Authors: Larco Pablo , Larco Pablo , Torres Daniel , Piñero David P.
Published: December 2020

The short-term safety and efficacy of intracorneal ring segment (ICRS) implantation in keratoconus eyes of children are investigated in this study. A retrospective interventional case series study including a total of 33 keratoconus eyes (age 8 to 17 years) that had undergone ICRS (Keraring segments, Mediphacos) implantation was conducted. Information about visual, refractive, pachymetric, corneal topographic and aberrometric, and corneal endothelial changes during a 3-month follow-up were extracted and analysed. A significant improvement was observed in logMAR corrected distance visual acuity (p = 0.005), combined with a statistically significant reduction in keratometric readings (p < 0.001). A reduction in the magnitude of corneal astigmatism of ≥1 D was observed in 52.8% of eyes. No significant changes were observed in corneal endothelial density (p = 0.317). Significant changes were found in the anterior vertical coma component (p = 0.002) as well as in the spherical aberration of the posterior corneal surface (p = 0.004). Only two relevant complications were described: one corneal microperforation with penetration of the ring segment into the anterior chamber (1 eye, 2.8%), and a case of ring extrusion (1 eye, 2.8%). ICRS implantation in children keratoconus eyes allows a reduction of corneal astigmatism, irregularity, and aberrations, leading to a significant visual improvement.

Published: December 2020

Fluctuations in solar radiation are one of the key factors affecting productivity and survival in habitat forming coastal macroalgae, in this regard, photoacclimation has a direct impact on the vulnerability and the capacity of seaweed to withstand, for instance, radiation excess. Here, we study ecophysiological responses through photosynthetic activity measurements under time-dependent (one year) fluctuations in solar radiation in the brown macroalga L. spicata. The responses presented seasonal patterns, with an increase in photosynthetic capacity during summer, expressed in greater maximal electron transport rate (ETRmax) and diminished thermal dissipation (NPQmax). Moreover, we studied photoprotective compounds (phenolic compounds) and total antioxidant capacity, which demonstrated an increase during periods of high solar radiation. In addition, content of photosynthetic pigment (Chla, Chlc and Carotenoids) increased under greater solar irradiance. The L. spicata can accumulate as reservoir photoprotective and antioxidant substances to withstand periods of high solar irradiance. All ecophysiological and biochemical responses in L. spicata indicate high photoacclimation and low vulnerability in the species, especially during with greater levels of solar irradiance.

A novel coronavirus first reported from China has resulted in a formidable outbreak globally threatening millions of human lives with unprecedented challenges. Society needs effective information source to combat this pandemic. Academic institutions would play an important role in disseminating science-based information and planning pandemic crisis. This study aims to examine how academic institutions around the world have been working in combating COVID-19 pandemic. Two hundred and thirty three high ranking universities representing 44 countries from six continents, viz. Africa, Asia, Europe, North America, South America, and Oceania were selected and their websites visited. Any information on COVID-19 updated in the websites were noted and classified. Universities from developed world (North America, Europe) and Oceania were found to be actively disseminating up-to-date information on COVID-19 with compared to those from developing world. All universities in Oceania, 96.66% universities in North America, 96.55% in Europe, 83% in South America, 61.25% in Asia, and 56% in Africa had information regarding COVID-19 in their websites. The high income coutries were facing high casulaties of the disease, and majority of their universities (85.71%) were disseminating up-to-date information through their websites. There exists a gap between the universities of developed and developing world in disseminating COVID-19 pandemic information.

Proximal Tubular Oxidative Metabolism in Acute Kidney Injury and the Transition to CKD
Authors: Schaub Jennifer A. , Venkatachalam Manjeri A. , Weinberg Joel M.
Published: December 2020

The proximal tubule relies on oxidative mitochondrial metabolism to meet its energy needs and has limited capacity for glycolysis, which makes it uniquely susceptible to damage during AKI, especially after ischemia and anoxia. Under these conditions, mitochondrial ATP production is initially decreased by several mechanisms, including fatty acid–induced uncoupling and inhibition of respiration related to changes in the shape and volume of mitochondria. Glycolysis is initially insufficient as a source of ATP to protect the cells and mitochondrial function, but supplementation of tricarboxylic acid cycle intermediates augments anaerobic ATP production, and improves recovery of mitochondrial oxidative metabolism. Incomplete recovery is characterized by defects of respiratory enzymes and lipid metabolism. During the transition to CKD, tubular cells atrophy but maintain high expression of glycolytic enzymes, and there is decreased fatty acid oxidation. These metabolic changes may be amenable to a number of therapeutic interventions.
Regional Citrate Anticoagulation Protocol for Patients with Presumed Absent Citrate Metabolism
Authors: Szamosfalvi Balazs , Puri Vidhit , Sohaney Ryann , Wagner Benjamin , Riddle Amy , Dickinson Sharon , Napolitano Lena , Heung Michael , Humes David , Yessayan Lenar
Published: December 2020

Background

Regional citrate anticoagulation (RCA) is not recommended in patients with shock or severe liver failure. We designed a protocol with personalized precalculated flow settings for patients with absent citrate metabolism that abrogates risk of citrate toxicity, and maintains neutral continuous KRT (CKRT) circuit calcium mass balance and normal systemic ionized calcium levels.

Methods

A single-center prospective cohort study of patients in five adult intensive care units triaged to the CVVHDF-RCA “Shock” protocol.

Results

Of 31 patients included in the study, 30 (97%) had AKI, 16 (52%) had acute liver failure, and five (16%) had cirrhosis at the start of CKRT. The median lactate was 5 mmol/L (interquartile range [IQR], 3.2–10.7), AST 822 U/L (IQR, 122–2950), ALT 352 U/L (IQR, 41–2238), total bilirubin 2.7 mg/dl (IQR, 1.0–5.1), and INR two (IQR, 1.5–2.6). The median first hemofilter life censored for causes other than clotting exceeded 70 hours. The cumulative incidence of hypernatremia (Na >148 mM), metabolic alkalosis (HCO3- >30 mM), and hypophosphatemia (P<2 mg/dl) were one out of 26 (4%), zero out of 30 (0%), and one out of 30 (3%), respectively, and were not clinically significant. Mild hypocalcemia occurred in the first 4 hours in two out of 31 patients, and corrected by hour 6 with no additional Ca supplementation beyond the per-protocol administered Ca infusion. The maximum systemic total Ca (tCa; mM)/ionized Ca (iCa; mM) ratio never exceeded 2.5.

Conclusions

The Shock protocol can be used without contraindications and is effective in maintaining circuit patency with a high, fixed ACDA infusion rate to blood flow ratio. Keeping single-pass citrate extraction on the dialyzer >0.75 minimizes the risk of citrate toxicity even in patients with absent citrate metabolism. Precalculated, personalized dosing of the initial Ca-infusion rate from a table on the basis of the patient’s albumin level and the filter effluent flow rate maintains neutral CKRT circuit calcium mass balance and a normal systemic iCa level.

Published: December 2020

Background

Human kidney stones form via repeated events of mineral precipitation, partial dissolution, and reprecipitation, which are directly analogous to similar processes in other natural and manmade environments, where resident microbiomes strongly influence biomineralization. High-resolution microscopy and high-fidelity metagenomic (microscopy-to-omics) analyses, applicable to all forms of biomineralization, have been applied to assemble definitive evidence of in vivo microbiome entombment during urolithiasis.

Methods

Stone fragments were collected from a randomly chosen cohort of 20 patients using standard percutaneous nephrolithotomy (PCNL). Fourier transform infrared (FTIR) spectroscopy indicated that 18 of these patients were calcium oxalate (CaOx) stone formers, whereas one patient formed each formed brushite and struvite stones. This apportionment is consistent with global stone mineralogy distributions. Stone fragments from seven of these 20 patients (five CaOx, one brushite, and one struvite) were thin sectioned and analyzed using brightfield (BF), polarization (POL), confocal, super-resolution autofluorescence (SRAF), and Raman techniques. DNA from remaining fragments, grouped according to each of the 20 patients, were analyzed with amplicon sequencing of 16S rRNA gene sequences (V1–V3, V3–V5) and internal transcribed spacer (ITS1, ITS2) regions.

Results

Bulk-entombed DNA was sequenced from stone fragments in 11 of the 18 patients who formed CaOx stones, and the patients who formed brushite and struvite stones. These analyses confirmed the presence of an entombed low-diversity community of bacteria and fungi, including Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria, and Aspergillus niger. Bacterial cells approximately 1 μm in diameter were also optically observed to be entombed and well preserved in amorphous hydroxyapatite spherules and fans of needle-like crystals of brushite and struvite.

Conclusions

These results indicate a microbiome is entombed during in vivo CaOx stone formation. Similar processes are implied for brushite and struvite stones. This evidence lays the groundwork for future in vitro and in vivo experimentation to determine how the microbiome may actively and/or passively influence kidney stone biomineralization.

As vantagens da História Cruzada para o estudo da História de Esparta no período clássico
Authors: Bantim de Assumpção Luis Filipe
Published: December 2020

A relação política das póleis no interior da Hélade sempre foi inevitável diante do mar Mediterrâneo, visto como um espaço relacional de dimensões específicas e limitadas. Diante disso, objetivamos analisar as relações políticas do navarco esparciata Lisandro na Hélade do período clássico por meio do arcabouço teórico da Análise do Discurso francesa e da Teoria de Redes, bem como pelo viés comparativista da História Cruzada. Nesse sentido, propomos que uma investigação munida de indícios de múltiplas temporalidades e espacialidades podem nos fornecer mecanismos para superar a tendência atenocêntrica da historiografia que considerou Lisandro e o basileús Agesilau II como os únicos responsáveis pela desestruturação de Esparta.
Terminalidad de la educación secundaria y formación para el trabajo en la Ciudad de Buenos Aires: el Bachillerato con Orientación Profesional
Authors: Belmes Armando , Rodrigo Ismael Álvaro
Published: December 2020

El propósito de esta comunicación es presentar algunos de los resultados de un estudio exploratorio, enmarcado en la Unidad de Evaluación Integral de la Calidad y Equidad Educativa (UEICEE), cuyo objetivo fue examinar un dispositivo de inclusión educativa, el Bachillerato con Orientación Profesional, destinado a adolescentes que, por distintas circunstancias asociadas a la vulnerabilidad social y educativa, han transitado trayectorias discontinuas en el sistema educativo. Este dispositivo se implementa desde 2015 en seis Centros de Formación Profesional de la Ciudad de Buenos Aires, articulando la enseñanza de las asignaturas básicas de la formación general de nivel Medio con un trayecto curricular de Formación Profesional inicial correspondiente a un sector de actividad específico.

El estudio analiza la estructura curricular y la organización institucional del dispositivo, y explora las particularidades de su implementación en cada uno de los centros, a partir de una estrategia metodológica cualitativa y cuantitativa que combina distintos tipos de fuentes, métodos y técnicas. Los mismos permiten advertir, a la par del trabajo “artesanal” docente y el profundo compromiso de los actores institucionales, una brecha entre el enunciado y la práctica. Esta brecha se constituye en una “zona gris” que evidencia las limitaciones para implementar un régimen académico flexible y superar la fragmentación disciplinar tradicional de la escuela secundaria en general y en particular de la técnica-profesional.
Usina de experiencias: políticas públicas, formación docente y Polos de Desarrollo desde las narrativas de los gestores del proyecto
Authors: Porta Luis , Aguirre Jonathan
Published: December 2020

La formación docente inicial y continua ha ocupado un lugar preponderante en la agenda de las preocupaciones pedagógicas y en los intereses ideológicos y políticos que se condensan en torno a la educación como fenómeno social. A lo largo del tiempo han transcurrido múltiples procesos que procuraron poner en marcha proyectos de formación diferenciados y con caracterizaciones propias. En este sentido, pueden identificarse experiencias que tuvieron diferentes intenciones de base, e intensidades variadas en sus efectos, pero que dejaron huellas que hoy perviven en las instituciones, en los sistemas educativos provinciales y en los propios sujetos. En el presente artículo recuperamos el proyecto “Polos de Desarrollo” como parte de una política pública para la formación docente a partir de las narrativas de los propios actores implicados. Para ello se utilizará el enfoque biográfico-narrativo, ya que otorga la posibilidad reconstruir y reorganizar la experiencia de los sujetos a través de sus propios relatos, atribuyendo significados al pasado con relación al presente y a las concepciones personales. Dicha política pública carece de visibilidad en las producciones académicas locales, de allí la centralidad de recuperar su riqueza y sus aportes a la formación de profesores.
Inflexiones de la realidad. Debates alrededor de la novela, el “compromiso” y el realismo en los años sesenta
Authors: Zangrandi Marcos
Published: December 2020

Este artículo analiza los debates acerca del realismo en la literatura argentina a partir de dos ensayos clave: Seis novelistas de la nueva promoción (1959) de Noé Jitrik y Realismo y realidad en la narrativa argentina (1961) de Juan Carlos Portantiero. A partir de ellos, se estudian los conceptos de “realismo” y de “realidad” que se convirtieron en bastiones de disputa en las transformaciones del campo cultural durante el cambio de décadas. De este modo, mientras que el texto de Portantiero, desde la tradición marxista, embiste contra la literatura del “compromiso” y señala, en cambio, la tradición de la literatura argentina de izquierda, Jitrik pone de manifiesto zonas de lo ambiguo y de lo liminar a partir de las cuales se pueden pensar otras dimensiones de la realidad en la literatura de aquel tiempo.
Formation of Stable Interphase of Polymer-in-Salt Electrolyte in All-Solid-State Lithium Batteries
Authors: Gao Hongcai , Grundish Nicholas S. , Zhao Yongjie , Zhou Aijun , Goodenough John B.
Published: December 2020

The integration of solid-polymer electrolytes into all-solid-state lithium batteries is highly desirable to overcome the limitations of current battery configurations that have a low energy density and severe safety concerns. Polyacrylonitrile is an appealing matrix for solid-polymer electrolytes; however, the practical utilization of such polymer electrolytes in all-solid-state cells is impeded by inferior ionic conductivity and instability against a lithium-metal anode. In this work, we show that a polymer-in-salt electrolyte based on polyacrylonitrile with a lithium salt as the major component exhibits a wide electrochemically stable window, a high ionic conductivity, and an increased lithium-ion transference number. The growth of dendrites from the lithium-metal anode was suppressed effectively by the polymer-in-salt electrolyte to increase the safety features of the batteries. In addition, we found that a stable interphase was formed between the lithium-metal anode and the polymer-in-salt electrolyte to restrain the uncontrolled parasitic reactions, and we demonstrated an all-solid-state battery configuration with a LiFePO4 cathode and the polymer-in-salt electrolyte, which exhibited a superior cycling stability and rate capability.

De la vanguardia artística a la música popular
Authors: Pujol Sergio
Published: December 2020

El artista visual argentino Jorge de la Vega (1930-1971) pensaba que las formas, las sonoridades y los lenguajes de la canción popular moderna constituían un medio expresivo muy potente. Con sus propias canciones, irreverentes y divertidas, el artista buscó rebasar el ámbito del Instituto Di Tella, las galerías de arte y los cenáculos de la crítica. Si el zeitgeist de la década del 60 fue el ánimo rebelde y transgresor, la manera que Jorge de la Vega eligió para cuestionar el establishment cultural de su tiempo consistió en situar en un pie de igualdad la vanguardia plástica y la canción popular. En definitiva, al preguntarnos por Jorge De la Vega en su doble vertiente de artista plástico y cantautor pop nos proponemos abordar un aspecto fundamental de la vida cultural de la década de los años 60 en la Argentina.

On Term Weighting for Spam SMS Filtering
Authors: DOGAN Turgut
Published: December 2020

Due to rapid development of the technology, the usage of mobile telephones and short message services (SMS) have become widespread. Thus, the number of spam SMS messages has dramatically increased and the significance of identifying and filtering of suchlike messages raised. Moreover, since they have also risk to steal users’ personal information; the problem of identifying and filtering of Spam SMS messages stays popular in terms of also information and data security. In this study, the classification performances of five different term weighting methods on three different datasets containing SMS messages categorized as Spam and legitimate are compared by using two classifiers for corresponding problem. The results obtained showed that reasonable weighting of SMS contents plays an important role in identifying of spam SMS messages. On the other hand, it can be expressed that real classification potential of term weighting schemes reflected betterly the with feature vectors created by using fifty and higher number of terms on especially Turkish and English SMS message datasets. In addition, it has been observed that value ranges of the classification results of obtained from term weighting methods on Turkish SMS message dataset is wider for than ones obtained in English SMS message datasets.

A survey of terrestrial mollusks was performed during their activity season in various spots of gardens, nurseries and agricultural fields in Cairo, Giza as well as in some neighboring areas between December 2014 and October 2018. Several invasive terrestrial gastropod species were identified. These gastropods are invasive and abundant pests causing considerable and serious damage to agricultural areas in the Nile Delta Region of Egypt. The specimens were collected from different locations in the governorates of Cairo and Giza. A total of 12 species (8 species of terrestrial snails and 4 of slugs) were identified by their shell characteristics and genital-anatomical characters. The following four species were identified for the first time in Egyptian gardens and nurseries: 1) Polygyra cereolus (Megerle von Mühlfeld, 1816), 2) Oxychilus cf. cellarius (O. F. Müller, 1774), 3) Zonitoides arboreus (Say, 1816) and 4) Laevicaulis alte (d’ A. de Férussac, 1822), which is particularly injurious to agricultural production. The other invasive species reported in this study were recorded in other agricultural fields and are common pests of gardens, nurseries and agricultural areas in Egypt. This study presents essential information on each species, their original and current distribution in Egyptian agricultural fields.

The article discusses the processing results of the vibration records from the dams and coastal slopes of the Charvak and Andijan water reservoirs of Uzbekistan during the weak earthquakes. It is shown, that the seismic monitoring systems were upgraded at the investigated objects. Analyzing seismic estimates, revealed, that the construction of the Charvak reservoir dam has a non-linear behavior, and it is manifested in the differences of the frequency range and transmission coefficient of the dam elements. According to the analysis of seismic data, obtained during the registration of weak earthquakes at the several measuring points of dams and coastal slopes of the Charvak and Andijan reservoirs, the vibration frequencies and the ratio of the vibration velocity amplitudes to the vibration velocity amplitudes of the reference station are varies greatly depending on the azimuth to the epicenter

Published: December 2020

The local magnitude scale ML was refined for the western part of the Eurasian Arctic on the basis of data from seismic stations operating on the archipelagos of Svalbard, Franz Josef Land, and Severnaya Zemlya: –logA0(R)=1.5*log(R/100)+1.0*10(–4)*(R–100)+3.0. Refinement was carried out on the basis of a sample of 167 earthquakes and 612 amplitude values at 5 seismic stations. The sample covered earthquakes that occurred in the main seismically active zones of the Eurasian Arctic for the period from January 2016 to April 2019. The refined scale can be applied in wide ranges of epicentral distances and magnitudes. The ML scale with the corresponding station corrections will be introduced into the practice of daily processing of seismological data from the western part of the Eurasian Arctic.

In the East of the high of Terskey-Alatau, in the northern part of the mountainous arch of Khan-Tengry at 28 January 2013 a strong (M=6.0) Saryzhaz earthquake there was with in-tensity of ~7-8 points, which to the intersection of deep regional faults cross Chilik with longitudinal Baiankol’skii was timed. This earthquake in the upper part of the earth’s crust (h=10 km) under the influence of compression stresses in the submeridional direction and near-horizontal stretching in the sublatitudinal direction occurred. The type of movement in the focus represents a shift on both possible planes of the rupture. Taking into account the most significant destruction in the Ili-Kazakh’s autonomous region and Aksu’s district of China, it can be assumed, that in focus a horizontally shift there was, that is sub-parallel to the Baiankol’s fault on the north-western strike. The earthquake had two foreshocks and over 1000 aftershocks. The area of aftershocks is 10x15 km. At 14 stations for main shock accelerograms and reaction spectra were obtained.
Mobile Phone Use for English Language Learning in a Dominican Republic University Classroom: A Qualitative Inquiry
Authors: Martiz Gisela , Recker Mimi
Published: December 2020

This qualitative case study investigated the use of mobile phones as tools to support English language learning in a higher education setting in the Dominican Republic. The study examined how a Dominican English language teacher and her students used mobile phones as educational tools, and which features these participants appropriated to engage in English language learning activities inside and outside the classroom. The study also explored social and physical factors that influenced participants’ mobile phone appropriation in a developing country context with limited technology access and infrastructure. Data collection took place for eight weeks through semi-structured interviews, informal conversations, classroom observations, and questionnaires, in a university English language center located in a Dominican urban city. Findings indicated that the teacher appropriated her mobile phone as a tool for connectivity, content delivery, assessment facilitation, time-management, and emergency power back-up. Students appropriated their mobile phones as tools for research and reference, note-taking, data gathering, collaboration and repository. In addition, mobile phone use for educational purposes facilitated the teacher’s instruction and enabled her to provide authentic activities for her students. Findings from this study shed light on how English Language teachers and students can integrate their own mobile technologies to support English language learning in a university classroom within a developing country context with uneven access to technology.

A Scaffolding Framework for Social Annotation in Online Classes
Authors: Zhu Xinran , Shui Hong , Chen Bodong
Published: December 2020

Web annotation is a genre of information technology that allows a user to annotate information in a shared document and anchor a discussion to the annotated information. When it is used socially in online classes, web annotation can support social reading, group sensemaking, knowledge construction, and community building (Chen, 2019; Kalir et al., 2020, Zhu et.al, 2020).To support several University of Minnesota instructors’ pivot to online teaching , we conducted a study that was focused on engaging undergraduate students in reading and discussing course materials in online classes. Following a co-design approach, we worked closely with instructors to design a generic scaffolding framework for social annotation activities and supported them to implement the framework, with course-specific customizations, in their classes. All participating courses are piloting a web annotation tool named Hypothes.is that is integrated in Canvas and allows students to read and annotate socially. This document describes the scaffolding framework, an important outcome of the study, which can be applied in various online/hybrid class settings.
On investigation of the inverse problem for a parabolic integro-differential equation with a variable coefficient of thermal conductivity

Published: December 2020

The inverse problem of determining a multidimensional kernel of an integral term depending on a time variable $t$ and $ (n-1)$-dimensional spatial variable $x'=\left(x_1,\ldots, x_ {n-1}\right)$ in the $n$-dimensional heat equation with a variable coefficient of thermal conductivity is investigated. The direct problem is the Cauchy problem for this equation. The integral term has the time convolution form of kernel and direct problem solution. As additional information for solving the inverse problem, the solution of the direct problem on the hyperplane $x_n = 0$ is given. At the beginning, the properties of the solution to the direct problem are studied. For this, the problem is reduced to solving an integral equation of the second kind of Volterra-type and the method of successive approximations is applied to it. Further the stated inverse problem is reduced to two auxiliary problems, in the second one of them an unknown kernel is included in an additional condition outside integral. Then the auxiliary problems are replaced by an equivalent closed system of Volterra-type integral equations with respect to unknown functions. Applying the method of contraction mappings to this system in the Hölder class of functions, we prove the main result of the article, which is a local existence and uniqueness theorem of the inverse problem solution.
Control of the motion of a circular cylinder in an ideal fluid using a source
Authors: Artemova E.M. , Vetchanin E.V.
Published: December 2020

The motion of a circular cylinder in an ideal fluid in the field of a fixed source is considered. It is shown that, when the source has constant strength, the system possesses a momentum integral and an energy integral. Conditions are found under which the equations of motion reduced to the level set of the momentum integral admit an unstable fixed point. This fixed point corresponds to circular motion of the cylinder about the source. A feedback is constructed which ensures stabilization of the above-mentioned fixed point by changing the strength of the source.
Simulation of the motion of a propellerless mobile robot controlled by rotation of the internal rotor
Authors: Klekovkin A.V.
Published: December 2020

We consider a propellerless robot that moves on the surface of a fluid by rotating of the internal rotor. The robot shell has a symmetric shape of NACA 0040 airfoil. The equations of motion are written in the form of classical Kirchhoff equations with terms describing the viscous friction. The control action based on the derived model is proposed. The influences of various model parameters on the robot's trajectory have been studied.
On normal coordinates in the vicinity of the Lagrangian libration points of the restricted elliptic three-body problem
Authors: Markeev A.P.
Published: December 2020

A planar restricted elliptic three-body problem is considered. The motions close to the triangular libration points are studied. The problem parameters (the eccentricity of the orbit of the main attracting bodies and the ratio of their masses) are assumed to lie inside the linear stability region of the libration points. The magnitude of eccentricity is considered small. A linear canonical, periodic in true anomaly transformation is obtained analytically up to the second degree of eccentricity inclusive that reduces the Hamiltonian function of the linearized equations of perturbed motion to real normal form in the vicinity of the libration points. This form corresponds to two harmonic oscillators not connected to one another, with frequencies depending on the problem parameters. In constructing the normalizing canonical transformation, the Depri-Hori method of the perturbation theory of Hamiltonian systems is used. Its implementation in the problem under study relies heavily on computer systems of analytical calculations.
