Published: April 2021

The multimodal Tongue Drive System (mTDS) is an assistive technology for people with tetraplegia that provides an alternative method to interact with a computer by combining tongue control, head gesture, and speech. This multimodality is designed to facilitate the completion of complex computer tasks (e.g. drag-and-drop) that cannot be easily performed by existing uni-modal assistive technologies. Previous studies with able-bodied participants showed promising performance of the mTDS on complex tasks when compared to other input methods such as keyboard and mouse. In this three-session pilot study, the primary objective is to show the feasibility of using mTDS to facilitate human-computer interactions by asking fourteen participants with tetraplegia to complete five computer access tasks with increased level of complexity: maze navigation, center-out tapping, playing bubble shooter and peg solitaire, and sending an email. Speed and accuracy are quantified by key metrics that are found to be generally increasing from the first to third session, indicating the potential existence of a learning phase that could result in improved performance over time.
Dramat imaginacyjny Wyspiańskiego: O niedrukowanej pracy Ireny Sławińskiej
Authors: Kaczmarek Wojciech
Published: April 2021

Artykuł prezentuje nieopublikowany tekst Ireny Sławińskiej Dramat imaginacyjny Stanisława Wyspiańskiego, pochodzący prawdopodobnie z roku 1938. Przywołane zostały możliwe źródła inspiracji oraz najważniejsze kroki badawcze, jakie wykonała Sławińska, rekonstruując imaginacyjną poetykę dramatów Wyspiańskiego (Protesilas i Laodamia, Legion, Wesele, Noc listopadowa, Wyzwolenie, Akropolis, Sędziowie). Jej analiza objęłakoncepcję przestrzeni, konstrukcję postaci, dialogi, funkcję chórów i didaskaliów, by pokazać, że cechą konstytutywną poetyki imaginacyjnej Wyspiańskiego jest zasada zacierania granicy między światem wizyjnym i realnym poprzez ich strukturalne powiązanie, przy jednoczesnym podkreślaniu ich zasadniczej odrębności. Sławińska przesunęła też moment ukształtowania się wizji nowego teatru Wyspiańskiego na rok 1895. W artykule zasygnalizowano, które wątki jej niepublikowanego tekstu mogą stanowić dziś inspirację dla dalszych badań nad twórczością Wyspiańskiego.
Restricted Extension of Sparse Partial Edge Colorings of Complete graphs
Authors: Casselgren Carl Johan , Pham Lan Anh
Published: April 2021

Given a partial edge coloring of a complete graph $K_n$ and lists of allowed colors for the non-colored edges of $K_n$, can we extend the partial edge coloring to a proper edge coloring of $K_n$ using only colors from the lists? We prove that this question has a positive answer in the case when both the partial edge coloring and the color lists satisfy certain sparsity conditions.

Contextos Fronteiriços e Óptica Transconstitucional na Efetivação de Direitos Fundamentais do Trabalhador: fortalecimento do mercosul sob à luz dos movimentos migratórios
Authors: Barreto Lopes Carlos Eduardo
Published: April 2021

Vez que o fenômeno globalizatório estabelece-se, a aquisição de meios facilitadores de integração e interação entre os países das regiões torna-se imprescindível, haja vista que, principalmente, pautas essenciais e comuns invadem o âmbito mundial – exigindo, em termos de Marcelo Neves, a metodologia do transconstitucionalismo e o trilho de caminhos de aprendizado recíproco. Na América Latina, especialmente, o processo de associação é engendrado por perspectivas históricas de submissão e dominação aos países de cultura imperialista. Assim, o presente artigo, por meio de estudo bibliográfico e jurisprudencial, busca analisar as condições jurídicas de ingresso e permanência do trabalhador migrante nos estados membros do Mercosul (Argentina, Brasil, Paraguai e Uruguai), sob à luz do intercâmbio regional, dos direitos humanos e do contexto do Estado Democrático de Direito.

The study aimed to identify the levels of credibility of Jordanian government and private television channels, and their degrees of commitment to the criteria of credibility, during the Coronavirus (COVID-19) crisis. It also aimed to reveal the degrees and types of changes in the credibility ratings of these channels before and during the crisis. The study relied on surveying the media audience as a research method, and it used a questionnaire as a data collection tool. The study sample represented a cross section of all Jordanians who were 18 years of age or older; a quota sample of 420 respondents was selected, divided equally among the three regions of Jordan (North, Central, and South). The results of the study showed that the most important credibility criteria adhere to by Jordanian government and private television channels were these: ‘depending on media professionals with experience and high competence’, ‘working for the public good’ and ‘relying on professional and ethical principles’. The government channel AlMamlaka topped the list of Jordanian television channels with the highest credibility among respondents. Roya Channel was shown to be the Jordanian television channel with the highest change in credibility ratings during the Coronavirus crisis.

Published: April 2021

Linear regression analyses commonly involve two consecutive stages of statistical inquiry. In the first stage, a single ‘best’ model is defined by a specific selection of relevant predictors; in the second stage, the regression coefficients of the winning model are used for prediction and for inference concerning the importance of the predictors. However, such second-stage inference ignores the model uncertainty from the first stage, resulting in overconfident parameter estimates that generalize poorly. These drawbacks can be overcome by model averaging, a technique that retains all models for inference, weighting each model’s contribution by its posterior probability. Although conceptually straightforward, model averaging is rarely used in applied research, possibly due to the lack of easily accessible software. To bridge the gap between theory and practice, we provide a tutorial on linear regression using Bayesian model averaging in , based on the BAS package in . Firstly, we provide theoretical background on linear regression, Bayesian inference, and Bayesian model averaging. Secondly, we demonstrate the method on an example data set from the World Happiness Report. Lastly, we discuss limitations of model averaging and directions for dealing with violations of model assumptions.

Published: April 2021

Summary. The article deals with the study of immune status of patients with osteomyelitis and trophic disorders of the shin tissues.

Objective: to evaluate the immune status of patients with shin-bone osteomyelitis and distrophic processes, and to study dynamics of immunological indices after surgical interventions (clearing and reconstructive restoring surgeries).

Materials and Methods. The immune status of 52 patients with posttraumatic osteomyelitis and trophic disorders of the shin tissues was studied. Clinical, immunological, and statistical research methods were used.

Results. The study revealed changes in immune defence and in trophic processes in tissues (bones, skin, and muscles) of the damaged extremity. Thus, the presence of changes in the immune status was established: a decrease in the number of T-lymphocytes, T-helpers, cytotoxic T-lymphocytes, as well as changes in the humoral immune system – a decrease in immunoglobulins M and G levels and an increace in the level of circulating immune complexes.

Conclusions. Changes in systemic immunity and local trophic disorders revealed in patients mutually aggravate the course of the pathological process and complicate its elimination.

Summary. There is no doubt that obtaining the true parameters of the hip joint makes it possible to determine the tactics of treatment of patients with cerebral palsy and it is a relevant object of studying.

Objective: to improve the results of diagnostics of pathology of the hip joint in patients with cerebral palsy by developing our own method.

Materials and Methods. The study included 20 patients (40 joints): 10 boys and 10 girls. Sixteen joints were operated on. The patients were 3-15 years of age. Femoral torsion according to Ruwe was clinically determined in all the patients; also, our own method for determining the clinical and roentgenogrammetric parameters of the hip joint (utility model patent No. 137567) was used.

Results. Our own method is simple, available and cheap; it may be used in all medical institutions with X-ray rooms for the diagnosis of hip joint pathology, as well as for screening.

Conclusions. Our own method is simple and reliable for determining the parameters of the hip joint in patients with cerebral palsy (femoral torsion, neck shaft angle, Wiberg's angle, Reimer's index, vertical migration index, acetabular angle, the angle of inclination of the acetabulum) in patients with cerebral palsy. Obtaining radiographic parameters of both hip joints after only one radiograph also significantly reduce the radiation load on the patient, since patients with cerebral palsy are the subject of screening throughout the entire period of their development. This method can be also applied during the examination and screening the patients with developmental disorders and other diseases of the hip joint.

Thanks to such unique properties as transparency and conductivity tin dioxide often utilize as transparent contact layer to produce displays, solar cells, and sensor devices. Hydrochemical method of deposition SnO2 films is a perspective due to its simplicity, and economical efficiency. The ionic equilibria analysis was carried out and the boundary conditions of Sn(OH)2 solid phase formation in the «Sn2+ – H2O – OH‾» system calculated. It was established, that tin(II) hydroxide may be obtain in the range 2 < pH < 12. Preliminary results allow to determinate an optimal mixture sourness interval 1 < pH < 5. Revealed, that the thickness of the Sn(OH)2 films strongly depends on the solution pH. Maximum value of 488 nm reached at pH = 8. Conductive SnO2 layers were obtained on a glass and sitall substrates with simultaneously presence of antimony chloride and ammonium fluoride followed by annealing in air. The thickness vs temperature and thickness vs tin initial salt concentration dependences were installed. The uniform tin hydroxide layers with a thickness of ~74 nm may be synthesized under pH = 2 conditions. By the electron microscopy method the average particle size was established changing from 200 to 400 nm for as-synthesized films, to ~20 nm for annealed which indicates the nanostructure nature of the films. The morphology, elemental composition and conductive properties of deposited films were investigated before and after heating stage. Studying the annealing temperature influence at the film resistance were identified a three temperature ranges within which the films sharply differ in their conductive properties, which is associated with phase and structural transformations in them. Shown, that the most conductive SnO2 films with the omic resistance 3-5 kOm/sm were obtained at the temperature range 620-870 K.

In this paper, using the method DFT/B3LYP of quantum chemical modeling, the stability of tautomeric, conformer, and anionic forms of 2-(2-(2-hydroxy-5-sulfamoylphenyl)hydrazone-3-oxo-N-phenylbutanamide (H2L) was studied and the geometric, electronic structure and bond lengths of molecules in various tautomeric forms were determined. It was shown that the stability of tautomeric molecules H2L as anionic forms was determined by the number of existing intermolecular hydrogen bonds (closing six-membered and five-membered cycles). The most stable tautomeric and conformal forms of an organic molecule and its dianion are proposed. The interatomic distances, angles, charges on atoms, IR and electronic absorption spectra of tautomeric forms of the molecule and dianion (H2L and L2-) were calculated. In this work, we studied the electronic absorption spectra in an aqueous-alcoholic solution and found that in an alkaline medium the molecule transforms into the ionic form with a bathochromic shift of 47 nm, corresponding to the results of the shift of the long-wavelength band electronic absorption spectra upon transition from the hydrazotautomer (form a) to the dianion form (form b’’) at 92 nm obtained by TD-DFT. The calculated results for the distance and angles between atoms are in good agreement with the experimental data of the molecule by X-ray diffraction analysis. It was shown that the IR spectrum of the stable form appears two absorption bands in the region of 1690 and 1655 cm–1, which are attributed to stretching vibrations of carbonyl groups (C=O), bound by a strong intramolecular hydrogen bond and the presence of the NH-hydrazone fragment of the 1H NMR spectrum confirmed the most stable for a neutral molecule is the hydrazone form.
Comparative DFT study of triplet and singlet elementary oxidation acts of the cyclohexane and 1,3-cyclohexadiene initiated by primary interaction with 3O2 under SCF conditions
Authors:   Kazan National Research Technological University, Kourdioukov Alexandre I.
Published: April 2021

The primary stages of the oxidation of model cyclohexane and 1,3-cyclohexadiene by triplet molecular oxygen and subsequent transformations involving triplet and singlet states were studied for the first time by the DFT method with the density functional B3LYP with the basis set 6-311++g(df,p). It was shown that, ceteris paribus, cyclohexane and 1,3-cyclohexadiene will be orders of magnitude more reactive compared to the activity of acyclic saturated hydrocarbons under SCF conditions when the oxidation process is initiated by the primary reaction with 3O2, which allows the propane-butane mixture to be effectively used as SCF conditions of heavy oils and use air purge to activate this process. The triplet associate complexes resulting from the oxidative cleavage of the secondary C–H bond of cyclohexane and 1,3-cyclohexadiene consist of hydrogen-bonded hydroperoxyl radical and cyclohexyl radical or 1,3-cyclohexadiene radical, respectively. These complexes can dissociate into unbound pairs of radicals, and therefore further reactions can proceed in the triplet or singlet direction. The singlet direction is characterized by hydrate-induced hydroperoxide-carbonyl transformation, as well as other hydrate-induced rearrangements. The triplet direction is characterized by the occurrence of triplet rearrangement, which in its essence is a triplet recombination of associated radicals. Associate triplet complexes can be agents of radical hydroperoxyl and alkyl activity, as well as agents of radical hydroxyl and alkoxyl activity. Most oxidative dehydrogenation reactions are absolutely real under a number of conditions, namely, they must take place under SCF conditions, as well as in the presence of an excess of SCF solvent necessary for the effective shift of thermodynamic equilibrium towards the target products in accordance with the Le Chatelier principle.

Interaction between 1,3-dimethylbenzimidazolinium iodide (as an analogue of 1,3-benzodithiolium and 1,3-benzothiolium and tropylium salts), aromatic Schiff bases, and sodium tetrahydroborate in tetrahydrofurane medium (in the presence of imidazole as a cation carrier, or without) at the ratio of starting reagents imine : 1,3-dimethylbenzimidazolinium iodide : sodium tetrahydroborate = 1:1:1 was studied. It was found out that, as basically distinct from the reaction of imines with analogues (1,3-benzodithiolium and 1,3-benzothiolium and tropylium salts) which, while reacting under similar conditions with Schiff bases, form accordingly the products of reductive heterylation – N-arylmethyl-4-(1,3-benzodithiol-2-il)aniline, or tropylation – N-arylmethyl-4-(7-cyclohepta-1,3,5-trienyl)aniline, whereas the reaction of imines with 1,3-dimethylbenz-imidazolinium iodide under similar conditions afforded N-arylmethylanilines in a high yield. This fact enables characterizing the 1,3-dimethylbenzimidazolinium iodide cation as more stable and less electrophilic due to an appreciable delocalization of a positive charge in the cation and, as a consequence, placing it as last (less reactive) in a series of known heteroanalogues (1,3-benzodithiolium > xanthilium > thioxanthilium > tropylium > N-methylacridinium > 1,3-dimethylbenzimidazolinium). The use of 1,3-dimethylbenzimidazoline as a donor of hydride-ion H (instead of sodium tetrahydroborate) also results in corresponding secondary aromatic amines as the reduction products of Schiff bases.

Published: April 2021

The interaction of sulfonate-containing aromatic poly- and copolyamides with acrylonitrile copolymers with N,N-dimethyl-N,N-diallylammonium chloride (DMDAAC) and N,N-diethylaminoethylmethacrylate (DEAEM) in organic and water-organic solutions was studied. It was shown that as a result of macromolecular reactions interpolyelectrolyte complexes (IPEC) forms. They are stabilized mainly by electrostatic forces. To characterize the interpolyelectrolyte complexes composition the φ parameter was used, that defines as the ratio of corresponding functional groups molar concentrations of interacting polyelectrolytes. The transformation degree in interpolymer reactions θ was calculated as the ratio of the salt bonds number between polyions to their maximum possible number. It was shown that the main factors determining the composition and structure of forming interpolyelectrolyte complexes are linear charge density of polyelectrolytes, the nature and composition of the solvent in which interpolymer reactions occurs. It is possible to obtain IPEC, the composition of which for the same polycation will vary from φ = 2.5 to φ = 1.0, changing these factors. It was found that at the complexation process is not accompanied by a change in the phase state of the interpolymer system, when the concentration of units with sulfonate groups in the macromolecular polyamide chain 5 mol.%. It was found that the introduction of polycation leads to the formation of IPEC structures in the form of particles with an average size of ~217.7 nm for poly-4,4'-(2-sodium sulfonate) – diphenylaminisophthalamide and ~248.1 nm in the case of poly-4,4'-(2-sodium sulfonate) -diphenylaminterephthalamide. It was shown that the decrease in the polymer content of units with sulfonate groups is accompanied by a decrease in the transformation degree from 0.65-0.66 to 0.18. It was found that the studied complexes can be transferred to the solution by increasing its ionic strength. The result obtained during this work can serve as a base for the development of for the manufacturing technology of film and membrane materials based on sulfonate-containing aromatic poly- and copolyamides.

In this paper, authors studied the integral antioxidant activity of kefir for baby food and the effect of the product's expiry date on this indicator. The integral antioxidant activity of kefir was determined on an “Expert-006” coulometer using coulometric titration with electro-generated bromine using rutin as a standard. The following points were chosen as control points for carrying out analytical work: release date, end of the expiry date, the period of time during which the food product, subject to storage conditions, must retain all of its properties specified in the regulatory documentation and a week after the expiration date. Such a trip allows us to determine a sample of fermented milk products that is distinguished by the highest biochemical value and high-quality preservation, and also to identify the brand of kefir for baby food and, as a result, the manufacturer, who should be preferred when buying goods. The object of the study in this work was several kefirs for children produced by OJSC «Zelenodolsk milk processing plant», OJSC «Lactis», LLC «Wimm Bill Dann». Studies have shown that the highest initial antioxidant activity was characterized by all control samples of kefir brand «For Babies» with the lowest declared expiry date. Moreover, an increase in the declared expiry date of sour-milk products led to a decrease in the value of the above indicator. A similar trend was observed when studying changes in the biochemical value of all studied samples during storage. The effect of storage duration on the integrated antioxidant activity of commercial products was evaluated by the level of its decrease (%) at the time of determination relative to its initial value. It was revealed that the kefir produced by OJSC «Zelenodolsk milk processing plant" had the highest integral antioxidant activity and was subjected to the least changes in this indicator during storage among all children's kefirs studied in the work.

Currently, the expansion of research to find new efficient and environmentally friendly plant growth regulators is an urgent task of agricultural biotechnology. One of the main requirements of the modern development of crop production using technologies for the use of new plant growth regulators is, along with the environmental friendliness of new drugs, both at the application stage for foliar feeding of plants and improving the quality of the final product. One of the new drugs that meet these requirements is a complex preparation of 1-ethoxysilatrane with crezacin. The work shows the high efficiency of the use of the new apple growth regulator in the processing of apple leaves. As a result of the studies, a synergism of the joint action of 1-ethoxysilatrane and crezacin as part of a complex preparation was revealed during foliar treatment of apple leaves of 3-4 phases and the beginning of flowering by spraying the drug in doses of 15 g/ha. The total increase in apple harvest during foliar treatment of tree leaves was 8.1% or 7.0 t/ha compared with the control. An increase in the quality indicators of gardening products was revealed when using the drug 1-ethoxysilatran with krezacin in terms of the content of dry substances, total sugar, vitamin C and pectin in the fruits. The content in the fruits of nitrates during foliar treatment with a new preparation of tree leaves is reduced by 17.9% compared with the control. The content in the fruits of apples of nitrates during foliar treatment with a new preparation of tree leaves decreases by 17.9%, the lead content by 44% compared with the control.

Oil is an environmentally hazardous substance of class 3 (moderately hazardous substances). However, during transportation, oil is classified as hazard class 1 and 2 (extremely hazardous and highly hazardous substances), since during transportation of oil and oil products there is a likelihood of spills of hazardous substances as a result of an oil pipeline breakdown, emergency wagon-tank wagon derailment during transportation by rail, oil tanker wrecks and accidents. Getting into the soil, soil microflora degradation occurs, respiratory processes are disrupted and the composition of humus and soil microorganisms changes. Hydrophobic compounds are especially dangerous for the roots of plants, which impede the flow of moisture and nutrients. The experiment of germination of sunflower seeds using various external factors, such as oil pollution in different concentrations (0.5%, 0.9%, 2.9%, 4.7%) and pre-processing of the gradient magnetic field. Magnetic field treatment was carried out with the help of a small-sized magnetoplasmic unit UMP-2. Comparative analysis of the root system of sunflower was carried out after germination in rolls of filter paper, planting of germinated seeds in universal soil for 30 days of plant growth. The obtained data indicate the stimulating effect of the magnetic field not only on the germination and growth parameters of plants, but also on the root system.

Published: April 2021

Salicylic acid is currently of little use, but its derivatives are one of the most large-tonnage drugs in the world. However, the natural sources of salicylic acid cannot satisfy the needs for its preparations and therefore the acid and its derivatives are obtained exclusively by synthetic means. Derivatives of salicylic acid are of great interest, due to their high reactivity and widespread use in medical practice as anti-inflammatory, antipyretic, analgesic, antimicrobial, antiseptic and anti-tuberculosis drugs. Currently, there is a fairly large body of data on the synthesis, structure, and biological properties of various derivatives of salicylic acid, however, it should be noted that derivatives of salicylic acid and various derivatives of amino acids and salicylic acid are poorly studied. The relevance of studying the properties of new transformed derivatives of salicylic acid is due to broad prospects that open the borders for realizing the potential for further chemical modification inherent in the structure of these new substances with a combination of several active groups: carbonyl and hydroxyl. Such a combination in a molecule of derivatives based on salicylic acid, containing known pharmacological groups in its structure, often leads to the appearance of a new high hemostatic activity. In the course of our work, we synthesized some esters based on salicylic acid, and also determined the antiplatelet and anticoagulant activity of the first synthesized substances. The study was conducted on the indicators of coagulogram in vitro on human donated blood. It was found that all provided compounds exhibit anti-aggregation activity, some of the compounds obtained by us exhibit anti-aggregation activity of more than 10%. All the experimental work was performed by us at the Department of Anesthesiology and Intensive Care with the course of the Institute of Continuing and Professional Education of the Bashkir State Medical University of the Ministry of Health of Russia on the basis of the Central Research Laboratory of the Bashkir State Medical University of the Ministry of Health of Russia and GBUZ RKB named after G.G.

Published: April 2021

The determinants and effects of bank bailout programs on the economy and society are still controversial. Using a Propensity Score Matching approach relying on 22 European countries, it was identified economic growth, economic freedom, total banking assets, and liquid assets to deposits and short-term funding ratio as the main drivers for the decision to adopt a bank bailout program. The results show that the adoption of bank bailout programs did not lead to an improvement in the banks’ solvency indicators or financial performance. Still, it has amplified financial stress and income inequality instead, hampering political stability, as well as social and economic conditions. The novelty of this research resides in adding a contribution to scarce literature covering the determinants of the decision to adopt a bank bailout program, also by comprehensively expanding the set of candidate variables that may have impacted the decision for Government intervention.
A Stochastic Theory of the Hierarchical Clustering. II. Halo Progenitor Mass Function and Large-scale Bias
Authors: Lapi Andrea , Danese Luigi
Published: April 2021

We generalize the stochastic theory of hierarchical clustering presented in Paper I by Lapi & Danese to derive the (conditional) halo progenitor mass function and the related large-scale bias. Specifically, we present a stochastic differential equation that describes fluctuations in the mass growth of progenitor halos of given descendant mass and redshift, as driven by a multiplicative Gaussian white noise involving the power spectrum and the spherical collapse threshold of density perturbations. We demonstrate that, as cosmic time passes, the noise yields an average drift of the progenitors toward larger masses, which quantitatively renders the expectation from the standard extended Press and Schechter (EPS) theory. We solve the Fokker–Planck equation associated with the stochastic dynamics, and obtain as an exact, stationary solution, the EPS progenitor mass function. Then we introduce a modification of the stochastic equation in terms of a mass-dependent collapse threshold modulating the noise, and solve analytically the associated Fokker–Planck equation for the progenitor mass function. The latter is found to be in excellent agreement with the outcomes of N-body simulations; even more remarkably, this is achieved with the same shape of the collapse threshold used in Paper I to reproduce the halo mass function. Finally, we exploit the above results to compute the large-scale halo bias, and find it in pleasing agreement with the N-body outcomes. All in all, the present paper illustrates that the stochastic theory of hierarchical clustering introduced in Paper I can describe effectively not only halos’ abundance, but also their progenitor distribution and their correlation with the large-scale environment across cosmic times.
Avoiding the Geometric Boundary Effect in Shear Measurement
Authors: Wang Haoran , Zhang Jun , Li Hekun , Shen Zhi
Published: April 2021

In image processing, source detections are inevitably affected by the presence of the geometric boundaries in the images, including the physical boundaries of the CCD, and the boundaries of masked regions due to column defects, bright diffraction spikes, etc. These boundary conditions make the source detection process not statistically isotropic and can lead to additive shear bias near the boundaries. We build a phenomenological model to understand the bias, and propose a simple method to effectively eliminate the influence of geometric boundaries on shear measurement. We demonstrate the accuracy and efficiency of this method using both simulations and the z-band imaging data from the third data release of the DECam Legacy Survey.

Authors: Li Jiadong , Liu Chao , Zhang Bo , Tian Hao , Qiu Dan , Tian Haijun
Published: April 2021

The M dwarf stars are the most common stars in the Galaxy, dominating the population of the Galaxy at faint magnitudes. Precise and accurate stellar parameters for M dwarfs are of crucial importance for many studies. However, the atmospheric parameters of M dwarf stars are difficult to determine. In this paper, we present a catalog of the spectroscopic stellar parameters (T
eff and [M/H]) of ∼300,000 M dwarf stars observed by both LAMOST and Gaia using the Stellar LAbel Machine (SLAM). We train a SLAM model using LAMOST spectra with APOGEE Data Release 16 labels with 2800 K < T
eff < 4500K and −2 dex < [M/H] < 0.5 dex. The SLAM T
eff is in agreement to within ∼50 K compared to the previous study determined by APOGEE observations, and the SLAM [M/H] agrees within 0.12 dex compared to the APOGEE observation. We also set up a SLAM model trained by the BT-Settl atmospheric model with random uncertainties (in cross validation) to 60 K and agreeing within ∼90 K compared to previous studies.

Published: April 2021

Introduction: The global COVID-19 pandemic originated from the Chinese city of Wuhan and gradually reached every end of the world. It has adversely affected economies of developed as well as underdeveloped countries, the subcontinent has been hit badly by the negative consequences of deadliest coronavirus. People are getting affected by the virus in large numbers and cases in growing on daily bases.

Methodology: The present study employs Automatic ARIMA through R package “forecast”, to predict the growing number of cases for upcoming 14 days starting on 1st July 2020 and ending on 14 July 2020. Using 107 daily observations of the confirmed cases of COVID-19, it seems an important concern to predict the cases to help governments of the region plan accordingly.

Results: The outcomes of the study indicate that ARIMA applied on the sample rationally predicts the confirmed cases of coronavirus for next 14 days in the subcontinent. An increased trend is observed for Pakistan and India with constant cases for Bangladesh in the coming 14 days.

Conclusions: Pakistan is having the highest predicted growth rate in terms of cases followed by India. Therefore, the governments need to build adequate policies in order to contain the spread of the virus.

Published: April 2021

Introduction: Since the first published cases of the Coronavirus disease known as COVID-19 in the city of Wuhan Hubei Province in China, up until to the time of preparation of this report in mid-September 2020, more than 30 million people have been infected all over the world. In March 2020, more than 300,000 cases have been reported all over Iraq. This study aims to represent data analysis, modelling and forecasting approaches to the presented data in the Kurdistan Region of Iraq. Methodology: The project involves mathematical models for forecasting and artificial simulations using particles. In the study, time series models including Simple Exponential Model, Holt’s Method and Brown’s Models have been used for the forecasting of the future potential rates in the area.  A series of simulations have been conducted to observe the possibilities of virus spread rates in a virtual world which represents a quarter of Erbil. Results: The outcome of the study shows how the disease have spread in Kurdistan, and what are the current rates to compare with neighbour regions. The modelling clearly shows that with cases still sporadically appearing, the risk of second and third waves of infections is high. Conclusions: Therefore, the regional government must reduce unnecessary gatherings to the lowest possible level. A scientific registry system of disease statistics must be put in place and rigorously updated all the times. We recommend the officials use a nationwide database provided to the public to monitor movement of every infected individual, to prevent further spread.
La psychanalyse de l’infans, l’avènement du langage, le désir inconscient et la demande implicite
Authors: Golse Bernard
Published: April 2021

Après avoir rappelé qu’aujourd’hui, l’œuvre de Françoise Dolto n’est presque plus enseignée dans les facultés de médecine, l’auteur montre que, pourtant, les conceptions actuelles de l’entrée de l’infans dans l’ordre du langage sont tout à fait compatibles avec les positions que celle-ci défendait, même si la musique du langage se trouve peut-être désormais davantage au cœur des modélisations. F. Dolto a utilisé la parole pour développer une psychanalyse de l’enfant en deçà du langage et, à ce titre, son œuvre a été véritablement pionnière et novatrice en ouvrant sur la question de la « demande implicite » nécessaire à prendre en compte chez les bébés et chez les patients très archaïques pour pouvoir penser la dynamique du désir inconscient.
