Aim. To analyse the data on spreading and population of the common hamster in Western Siberia from the mid‐20th to early 21st centuries and to determine the major predictors affecting these parameters.Material and Methods. Long‐term data on species’ population from the Zoomonitor Databank (Institute of Systematics and Ecology of Animals of the Siberian Branch of the Russian Academy of Sciences, ISEA SB RAS), populace survey data and field observations provided by scholars over recent years were used. The maximum entropy method was used to model the species’ ecological niche and range based on 82 common hamster sighting spots in Western Siberia. 19 bioclimatic factors as well as various soil types were used.Results. The reduction of range and threefold decrease of common hamster population until the 90s of the last century and a local increase in the number of the population at the beginning of the 21st century were noted. The main causes of the population decline include extensive extermination through the procurement of common hamster fur skins and limiting the harm caused as well as agricultural area size dynamics. The bioclimatic correlations revealed of the distribution of the common hamster, considered together with models of climate changes, suggest the possibility of common hamster obsolescence in modern steppe areas and its according repopulation of the large river bottomlands to the north of the current range.Conclusion. For the Asian section of its range, the species’ status is not so disastrous due to less prominent factors negatively impacting the population. The lack of previous studies of the species’ ecology in Western Siberia calls for the conducting of multi‐aspect studies, including monitoring the tendencies of the limiting factors’ dynamics.

Aim – to study the biocontrol properties of B. velezensis BZR 336g and B. velezensis BZR 517 strains against Fusarium pathogens using the fungus Fusarium graminearum as an example and to reduce the accumulation of deoxynivalenol (DON) and zearalenone (ZEN) in vitro.Materials and Methods. A study of the toxinogenicity of F. graminearum fungal strains was undertaken on rice and wheat grains and the effect of B. velezensis BZR 336g and B. velezensis BZR 517 strains on the growth of the fungus was studied on wheat grains and by the double cultures method. An experiment to study the effect of a liquid culture and supernatant of bacteria was carried out on wheat grains and the content of DON and ZEN in wheat grains was analyzed by HPLC and enzyme immunoassay.Results. It was found that two strains of the fungus F. graminearum were able to produce a high level of mycotoxins, while the strain F. graminearum 60318 had a higher growth rate. The B. velezensis BZR 336g and B. velezensis BZR 517 strains produced lipopeptide exometabolites and inhibited the growth of the F. graminearum 60318 strain. in vitro, while the content of ZEN remained at the control level.Conclusion. The ability of two strains of bacteria B. velezensis BZR 336g and B. velezensis BZR 517 to suppress the growth of the fungus F. graminearum 60318, as well as to inhibit the accumulation of mycotoxins in wheat grain in vitro, suggests that an increase in the content of antagonist bacteria B. velezensis BZR 336g and B. velezensis BZR 517 in the wheat microbiota can contribute to the suppression of the growth and harm of the fungus F. graminearum 60318.

Published: July 2022

Autonomous determination of the latitude of the place of movable and immovable objects is used as an independent task, as well as the task of determination of the initial value of latitude for operation of both platform and platform-free navigation systems. To solve these problems, it is necessary to have an inertial measurement unit (IMU) with at least three gyroscopes and three accelerometers. When using the IMU, executed by MEMS technology, the output signals of micromechanical gyroscope and accelerometers have significant noise components. Kalman filter is usually used to filter such signals. However, for this purpose it is necessary to know, besides the exact mathematical model of sensitive elements, many of their initial random characteristics.
In the article, the research was conducted in order to investigate the use of wavelet transformation for the filtering of output signals of micromechanical accelerometers and gyroscopes for autonomous determination of the latitude of the place. The peculiarity of using wavelet transform for noisy signals is that due to changing scale, wavelets can detect differences in process characteristics on different scales, and with help of the shift we can analyze process properties at different points on the whole investigated interval. Due to the properties of this system's fullness that it is possible to restore the process by means of inverse wavelet transform. The efficiency of the developed method of increasing the accuracy of the autonomous determination of the latitude of the IMU on the basis of micromechanical gyroscope and accelerometers has been experimentally confirmed. The projections of the angular velocity of Earth rotation and gravitational acceleration were obtained from the IMU made by MEMS technology. After that, the signals of the gyroscopes and accelerometers of the inertial measuring unit were filtered, using the wavelet ‘Daubechies 10’ in decomposition, and averaged. These signals were used in a computational algorithm to determine the latitude. The results showed that, unlike the well-known Kalman filter, which almost did not increase the accuracy of the latitude calculation, wavelet denoising and further averaging reduced calculation error by almost twice.
MODELING OF MOBILE ROBOT WITH OBSTACLE AVOIDANCE USING FUZZY CONTROLLER
Authors: Khudaverdiyeva Mahabbat 
Published: July 2022

This paper presents the modeling of a robot's navigation using ultrasonic sensors under uncertainty. The robot tries to avoid obstacles by using the fuzzy logic controller to process the data coming from three ultrasonic sensors. To assess the performance of fuzzy logic optimized robot navigation controller with ultrasonic sensors, which measure the distance by calculating the time spent on the object and its return, the obstacles are placed in front of, left, and right of the robot. Mamdani fuzzy reasoning system is used for the designed controller for its intuitive properties and fewer setting parameters which reduces the amount of time spent on the programming of the controller. 25 rules are considered to cover a robot’s possible interactions with obstacles. For an easy understanding of navigation architecture and rapid algorithm implementation, in this paper, a MATLAB simulation framework is developed. MATLAB/Simulink is one of the best simulation tools required to design the architecture and verify algorithms with real-time constraints. Resultant models of the fuzzy optimized controller demonstrate the superior performance of the fuzzy logic controller with high adaptability to the environment while maintaining a sufficient level of accuracy. The designed fuzzy controller can be used in microprocessor/microcontroller-based robots owing to easiness in implementation and coding.

Published: July 2022

Abstract
Background Shallow shotgun metagenomics (SSM) has been recently suggested as a promising strategy to study human microbiota, providing nearly identical taxonomic profiles to deep shotgun metagenomics but at a sequencing cost as low as that of metabarcoding. To help clinical researchers determine whether shallow sequencing is appropriate for their projects, it is crucial to ascertain the accuracy of the information it provides, compared to deep sequencing. Here, we design a mapping-based workflow to build taxonomic profiles from SSM data and assess its accuracy at varying sequencing depths at both sample and cohort levels using extensive simulations and several public data sets. Results To identify genuinely present species and spuriously identified ones, we propose a novel data-driven filtering method based on machine learning techniques that largely outperforms basic filtering strategies based on pre defined thresholds, resulting in reliable taxonomic profiles at different sequencing depths, ranging from 50K to 10M reads/samples. Up to 90% of species with relative abundances higher than 4.10−4 were recovered correctly at 500K reads/sample showing that only information about rare taxa is lost at shallow depths. Furthermore, our results clearly show that SSM is able to correctly recover relevant biological signal from the confidently identified taxa, such as differences between groups of patients and diagnosis-like classification. Conclusions This study confirms that SSM is suitable for clinical research on human gut microbiota. We recommend that researchers should consider moving from 16S to SSM to limit biases in taxonomic profiles, or moving from deep to shallow sequencing, when functional analyses are not the main focus, to reduce costs and be able to include more patients in research projects.
Spatial Associations of Long-term Exposure to Diesel Particulate Matter with Seasonal and Annual Mortality Due to COVID-19 in the Contiguous United States
Authors: Mathieu Martine , Gray Joshua , Richmond-Bryant Jennifer 
Published: July 2022

Abstract
Background
People with certain underlying respiratory and cardiovascular conditions might be at an increased risk for severe illness from COVID-19. Diesel Particulate Matter (DPM) exposure may affect the pulmonary and cardiovascular systems. The study aims to assess if DPM was spatially associated with COVID-19 mortality across three waves of the disease and throughout 2020.
Methods
We tested an ordinary least square (OLS) model, then two global models, spatial lag model (SLM) and spatial error model (SEM), designed to explore spatial dependence, and a geographically weighted regression (GWR) model designed to explore local associations.
Results
The GWR model found that associations between COVID-19 deaths and DPM concentrations may increase up to 57, 36, 43, and 58 deaths per 100,000 people in some US counties for every 1 µg/m3 increase in DPM concentration. Relative significant positive association are observed in New York, New Jersey, eastern Pennsylvania, and western Connecticut for the wave from January to May, and in southern Florida and southern Texas for June to September. The period from October to December exhibit a negative association in most parts of the US, which seems to have influenced the year-long relationship due to the large number of deaths during that wave of the disease.
Conclusions
Our models provided a picture in which long-term DPM exposure may have influenced COVID-19 mortality during the early stages of the disease, but that influence appears to have waned over time as transmission patterns evolved.

Abstract
Background: This study aimed to investigate the impacts of calorie restriction and exercise as preoperative interventions in laparoscopic sleeve gastrectomy.Methods: Sixteen patients with obesity who underwent laparoscopic sleeve gastrectomy were enrolled, comprising 4 men and 12 women aged 33–62 years (mean age, 44.8 years). Their mean body weight and body mass index were 124.7 kg and 46.5 kg/m2, respectively. These patients underwent calorie restriction and exercise for a mean duration of 5.9 months before the surgery. The effect of this preoperative intervention on the postoperative outcome was then evaluated.Results: The patients achieved a weight loss of 8.3% (10.8 kg). The visceral fat area significantly decreased by 5.5%, whereas the skeletal muscle mass remained unaffected. Furthermore, the good-responder group (preoperative weight loss > 8%) showed a significantly higher percentage total weight loss (%TWL) at 1 year postoperatively than the poor-responder group (preoperative weight loss < 8%). In the multivariate analysis, preoperative weight loss of >8% revealed the independent factor of correlating 25% ≤ %TWL at 1 year postoperatively.Conclusions: Preoperative intervention with calorie restriction and exercise is effective for postoperative weight loss in laparoscopic sleeve gastrectomy.
