A global, spherical finite-element model for post-seismic deformation using Abaqus
Authors: Nield Grace A. , King Matt A. , Steffen Rebekka , Blank Bas 
Published: March 2022

Abstract. We present a finite-element model of post-seismic solid
Earth deformation built in the software package Abaqus (version 2018). The model
is global and spherical, includes self-gravitation and is built for the
purpose of calculating post-seismic deformation in the far field
(>∼300 km) of major earthquakes. An earthquake is
simulated by prescribing slip on a fault plane in the mesh and the model
relaxes under the resulting change in stress. Both linear Maxwell and
biviscous (Burgers) rheological models have been implemented and the model
can be easily adapted to include different rheological models and lateral
variations in Earth structure, a particular advantage over existing models.
We benchmark the model against an analytical coseismic solution and an
existing open-source post-seismic model code, demonstrating good agreement
for all fault geometries tested. Due to the inclusion of self-gravity, the
model has the potential for predicting deformation in response to multiple
sources of stress change, for example, changing ice thickness in
tectonically active regions.

Published: March 2022

Abstract. This paper describes GCAM-USA v5.3_water_dispatch, an open-source model that represents key interactions across economic, energy, water, and land
systems in a consistent global framework with subnational detail in the United States. GCAM-USA divides the world into 31 geopolitical regions
outside the United States (US) and represents the US economy and energy systems in 51 state-level
regions (50 states plus the District of Columbia). The model also includes 235 water basins and 384 land use regions, and 23 of each fall at least
partially within the United States. GCAM-USA offers a level of process and temporal resolution rare for models of its class and scope, including
detailed subnational representation of US water demands and supplies and sub-annual operations (day and night for each month) in the US electric power
sector. GCAM-USA can be used to explore how changes in socioeconomic drivers, technological progress, or policy impact demands for (and production
of) energy, water, and crops at a subnational level in the United States while maintaining consistency with broader national and international
conditions. This paper describes GCAM-USA's structure, inputs, and outputs, with emphasis on new model features. Four illustrative scenarios
encompassing varying socioeconomic and energy system futures are used to explore subnational changes in energy, water, and land use outcomes. We
conclude with information about how public users can access the model.
Improving radar-based rainfall nowcasting by a nearest-neighbour approach – Part 1: Storm characteristics
Authors: Shehu Bora , Haberlandt Uwe 
Published: March 2022

Abstract. The nowcast of rainfall storms at fine temporal and spatial resolutions is
quite challenging due to the unpredictable nature of rainfall at such
scales. Typically, rainfall storms are recognized by weather radar and extrapolated in the future by the Lagrangian persistence. However, storm
evolution is much more dynamic and complex than the Lagrangian persistence,
leading to short forecast horizons, especially for convective events. Thus, the aim of this paper is to investigate the improvement that past similar
storms can introduce to the object-oriented radar-based nowcast. Here we propose a nearest-neighbour approach that measures first the similarity
between the “to-be-nowcasted” storm and past observed storms and later uses the behaviour of the past most similar storms to issue either a single
nowcast (by averaging the 4 most similar storm responses) or an ensemble nowcast (by considering the 30 most similar storm responses). Three questions are tackled here. (i) What features should be used to describe storms in
order to check for similarity? (ii) How should similarity between past storms be measured? (iii) Is this similarity useful for object-oriented nowcast? For
this purpose, individual storms from 110 events in the period 2000–2018
recognized within the Hanover Radar Range (R∼115 km2), Germany, are used as a basis for investigation. A “leave-one-event-out”
cross-validation is employed to test the nearest-neighbour approach for the prediction of the area, mean intensity, the x and y velocity components, and
the total lifetime of the to-be-nowcasted storm for lead times from + 5 min up to + 3 h. Prior to the application, two importance analysis methods (Pearson correlation and partial information correlation) are
employed to identify the most important predictors. The results indicate
that most of the storms behave similarly, and the knowledge obtained from such similar past storms helps to capture better the storm dissipation and
improves the nowcast compared to the Lagrangian persistence, especially for convective events (storms shorter than 3 h) and longer lead times (from
1 to 3 h). The main advantage of the nearest-neighbour approach is seen when applied in a probabilistic way (with the 30 closest neighbours as
ensembles) rather than in a deterministic way (averaging the response from the four closest neighbours). The probabilistic approach seems promising, especially
for convective storms, and it can be further improved by either increasing the sample size, employing more suitable methods for the
predictor identification, or selecting physical predictors.
Analysis of the sensitivity and specificity of ultrasound elastometry of the liver in women with chronic hepatitis C
Authors: Chernov V. S. 
Published: March 2022

Introduction. Despite the success in the treatment of chronic hepatitis C (HCV), the incidence of HCV remains at a high level, and the assessment of the degree of liver fibrosis is relevant in all patients with HCV.The aim of the study was to conduct a comparative diagnosis of the stages of liver fibrosis in women with chronic hepatitis C according to ultrasound elastometry and biopsy.Materials and Methods. To achieve this goal, a comprehensive clinical, laboratory (including virological), instrumental examination of 93 patients with HCV of reproductive age was conducted.Results. When interpreting the results, it was found that ultrasound elastometry in women with chronic hepatitis C is comparable to the results of percutaneous puncture liver biopsy.Discussion. Chronic hepatitis causes significant economic damage to health systems. The main factor affecting the reduction of morbidity and the risk of complications is the early diagnosis of HCV infection and timely antiviral therapy. The main objective of therapy is to achieve a stable virological response (SVR), as well as to reduce the activity of inflammation and the stage of AF in patients with HCV. The isolated use of serum markers of fibrosis and ultrasound elastometry of the liver at the early stages of the disease is not informative enough, so it is advisable to use a combination of different techniques, and at the CP stage, a puncture biopsy can be safely replaced with ultrasound elastometry of the liver, especially for the purpose of dynamic monitoring of patients with HCV.Conclusion. According to the comparative ROC-analysis of the results of ultrasound elastography and puncture liver biopsy, the high sensitivity and specificity of these methods for diagnosing liver fibrosis was established. The comparability of ultrasound elastography of the liver with the results of puncture biopsy, in young women, increases with the progression of liver fibrosis, and can be used to determine its degree.
Combined neurodegenerative disease associated with mutations in SLC5A7 and TGM6 genes
Authors: Epifanov P. A. , Dmitriev A. V. , Volkova L. I. 
Published: March 2022

Introduction. Hereditary neurodegenerative diseases are a large genetic deterministic group of nosologies, which is based on the clinic of steadily progressing processes of destruction of neuronal systems. Damage to the nervous system can have various combinations, but the most common are atrophy of the cerebellum, brain stem, spinal cord columns, and also possible damage to the peripheral nervous system. Despite the classical descriptions of the clinical picture of various forms of neurodegenerative pathology and the corresponding genetic markers of the disease, in the practice of a neurologist, there are cases that are difficult to determine the nosological form of the disease.Materials and methods. The article describes a case of combined hereditary pathology associated with laboratory-confirmed mutations in the SLC5A7 genes (associated with the development of type 7A hereditary motor sensory neuropathy) and TGM6 (affecting the development of type 35 spinocerebellar ataxia) and the clinical picture of lower spastic paraplegia.Results. The clinical case presents a combined form of hereditary spastic paraplegia with pseudobulbar syndrome, mild motor-sensory neuropathy of the lower extremities, signs of cerebellar hypotrophy on MRI and moderate impairment of walking and speech function against the background of two mutations previously identified in type 35 spinocerebellar ataxia and hereditary motor-sensory ataxia of type 35 type 7A neuropathy.Discussion. Diagnosis of nosological forms of hereditary pathology, manifested by a combination of lesions of the peripheral and central nervous systems, requires a detailed analysis of the hereditary history, neurological status and genetic examination results from a neurologist.Conclusion. The clinical case demonstrates polymorphism of clinical manifestations of hereditary forms of neurodegenerative pathology and a possible combination of various phenotypic and genotypic variants.

Introduction. Rabbits are used as convenient models for studying drug cardiotoxicity. Echocardiography is one of the most informative non-invasive methods of assessing the cardiovascular system function. In literature, there is no clearly formulated protocol for heart ultrasound examination in rabbits. Purpose was the systematization of literature data on echocardiography techniques in rabbits.Materials and methods. The sources search involved the Scientific Electronic Library eLIBRARY.RU and the National Library of Medicine information base (PubMed.gov). The search covered the 15-year period. Original or review articles containing a detailed description of the echocardiography technique were included.Results and discussion. For animals anesthesia before the study, various drugs combinations based on ketamine, xylazine, medetomidine, zolazepam, tiletamine are used. In rabbits, it is possible to use M-, B-, Doppler echocardiography modes in a wide frequency range (5 – 12 MHz). Parasternal longitudinal, parasternal transverse and apical ultrasound approaches are applied. The parameters of the transmitral blood flow (peak A, peak E, ratio A/E, peak E', the magnitude of regurgitation), as well as the contractile function of the left ventricle (end systolic and diastolic volumes and sizes, stroke volume, cardiac output, shortening fraction) are subject to assessment. The Teicholz and Simpson methods can be used to calculate the ejection fraction. The literature under survey coveres listed parameters of normal values for various ages’ rabbits.Conclusion. Echocardiography is a relatively affordable non-invasive method for studying the state of cardiovascular system in rabbits in an experiment. The method can be used to analyze myocardium size, left ventricle contractile function, and assess the state of heart valvular apparatus. At present, normal values of echocardiographic parameters in rabbits have been experimentally established, which adds to the informative value of the method. Qualitative study performance requires special preparation, including careful animal anesthesia, the choice of the approaches and modes used.
Vaccination against covid-19: the opinion of medical students
Authors: Matveeva E. S. , Fedorova A. M. 
Published: March 2022

Introduction. One of the pressing issues in public health today is the fight against the COVID-19 pandemic, including vaccine prophylaxis, its possibilities, necessity and safety. Proper professional advocacy plays an important role in the success of the vaccination campaign. Medical school students are also part of the professional community, who are as close as possible to the population and can be a source of information for them to influence their decisions about whether or not to vaccinate. The aim of the work was to study the attitudes of medical university students, as carriers of special information, toward vaccination against COVID-19. Materials and methods. A questionnaire survey was administered to 151 medical university students from Chelyabinsk and Ekaterinburg, mainly from the 4th to 6th years of medical, pediatric, and preventive medicine faculties. Results. Many of the trainees participating in the study are familiar with the new coronavirus infection (have themselves had an infection, are involved in providing medical care to patients with the new coronavirus infection), and more than 80% have been vaccinated against COVID-19. 63.0% of unvaccinated respondents do not plan to vaccinate in the near future, half of them due to uncertainty about the effectiveness of the vaccine. 44.9% of all respondents were not afraid of adverse effects of vaccination, and a large proportion (55.1%) expected reactions and even complications after vaccinated against COVID-19. They consider vaccination to be effective against COVID-19 47.5%, and 52.5% of those surveyed are not sure about vaccination effectiveness. Discussion. The effectiveness of vaccination for airborne infections is determined by the one-step coverage of a large (at least 70.0%) portion of the population. Most of the students surveyed intend to recommend vaccination against COVID-19 (almost 63%); however, 37.1% are not yet ready to do so. The motivations for their own vaccination are equally understanding of its necessity and fear of administrative restrictions. The study participants form their judgments about the problem under study mainly on the basis of popular publications and mass media appearances, which is confirmed by their low appeal to official statistics and special sources. Conclusion. To date, medical university students have not had a pronounced interest in learning about the new coronavirus infection, so the educational process under the COVID-19 pandemic needs to pay special attention to the problem under discussion.
Cystic adenomatous lung malformation of type II in the newborn, problems of early diagnosis
Authors: Shestak E. V. 
Published: March 2022

Introduction. Cystic adenomatous malformation (CAM) is a congenital lung malformation resulting from abnormal morphogenesis of lung branching at different stages and in different parts of the tracheobronchial tree, with formation of cysts. The incidence of CAM is one case per 8,300-35,000 live births. The modern classification distinguishes four types of CAM. The aim of the work was to analyze the features of the course of the disease and radiological signs that can help the doctor to suspect the presence of congenital lung malformations in the newborn in the early stages of manifestation, justify additional diagnostic methods, and timely choose an appropriate treatment tactic. Material and methods. The article presents the clinical observation of a newborn infant with type II CAM and concomitant disease «early neonatal sepsis». Medical documents are used, where the results of clinical examination, instrumental (X-ray, ultrasound, CT) and laboratory methods of investigation are presented. Data of histological examination of biomaterial obtained intraoperatively are presented. Results. An analysis of the clinical and radiological dynamics is given. Based on the examination, congenital malformations were detected, and surgical treatment was performed. The child was discharged from the hospital on the 35th day of life in a satisfactory condition. A detailed analysis of diagnostic limitations at each stage of the child's life was conducted. Discussion. Diagnosis of CAM in the early stages was difficult not only because of the nature of the malformation, but also because of the clinic of sepsis, which was the leading one in the first days of life. The morphology of the malformation leads to problems with its prenatal diagnosis and the lack of a clear radiological and ultrasound picture in the postnatal period. Conclusion. In any case of recurrent air leak syndrome, differential diagnosis of congenital pulmonary malformations and the use of CT or MRI for accurate imaging seems reasonable.
Current views on the assessment of vascular wall elasticity in pregnant women with arterial hypertension
Authors: Kolobova S. O. , Borovkova N. U. 
Published: March 2022

Introduction. Arterial hypertension is the most common somatic pathology in pregnant women. Arterial hypertension is a factor of high risk for the development of severe preeclampsia, placental insufficiency, intrauterine growth restriction, premature birth, maternal and perinatal mortality, nervous disorder and vascular heart disease of newborns and women’s distant cardiovascular disorders. The pathogenesis of gestational complications is associated with pathology of placentation, endothelial dysfunction and a decrease in vascular elasticity. The pathogenesis has not studied yet. Nowadays there are no tests with enough sensitivity and specificity ensuring early diagnostics and risk identification at development of great obstetric syndromes. Aim of the study was to improve our understanding about a clinical and prognostic role of vascular wall elasticity in pregnant women with arterial hypertension. Materials and Methods. We searched publications and analyzed literature using various scientific databases, including Index Medicus, PubMed/MEDLINE, Embase, Cochrane Library and Russian scholarly journals related to obstetrics, gynecology, cardiology for the last 9 years. Results and Discussion. Today changes in the elastic properties of arteries is a modern marker of a high risk of cardiovascular events in patients with essentialhypertension. Endothelial dysfunction develops already in the early stages of arterial hypertension and initiates structural changes in the vascular wall and an increase in arterial stiffness. High activity of the sympathetic nervous system is the cause of changes in the elastic properties of arteries in pregnant women with arterial hypertension. Conclusion. The role of vascular wall elasticity in pregnant women with arterial hypertension is of tremendous importance and deserves close attention. The study of elastic properties of vessels is relevant for assessing the risk of gestational complications in pregnant women with arterial hypertension.
