Published: May 2023

Logical, systematic, and comparative legal methods of research were used in this article. In particular, first of all, the development of legal norms related to mitigating circumstances was described, as well as the scientific views and research of scientists about it, and the similarities and differences between them were described in detail. At the same time, a comparative analysis was made with the types of mitigating circumstances; their problematic aspects were identified and described sequentially. Also, it was reasonably analyzed that in the first part of Article 55 of the Criminal Code, in addition to mitigating future punishment, special mitigating circumstances allow exemption from criminal liability by applying one of the provisions of Articles 64–67 of the Criminal Code. At the same time, the doctrine of criminal law and existing scientific research were analyzed, and reasonable theoretical proposals and recommendations were developed in this regard.

Published: May 2023

This article presents a scientific and theoretical analysis of issues related to the object of crimes against the freedom of a person, which is considered one of the main constitutional rights of citizens. The purpose of this study is to give a general description of crimes against the freedom of the person, to highlight their social danger, to analyze the object of crime in this category of acts, and to draw conclusions. Protection of human life, liberty, and freedom from various illegal acts has been an urgent and important issue at all times. For this reason, the laws of our country pay special attention to the protection of these human rights and interests. For example, in the Criminal Code of the Republic of Uzbekistan, a person, his rights and freedoms are included in the scope of objects of criminal law protection, and in Articles 135-141 of the Criminal Code, responsibility for crimes against the freedom, honor, and dignity of a person is defined and this indicates particular importance. In this research work, the types of crimes against the freedom of a person, and their general, special, related, and direct objects are analyzed. Historical, systematic, logical (analysis, synthesis), and comparative-legal methods of analysis of the practice of applying the law of scientific knowledge have been used in the research process. As a result of the research, the views of national and foreign scientists, and the contents of the norms defined in the relevant regulatory legal documents have been clarified, and the author’s conclusions on each issue have been stated.

The special military operation of the Russian Federation in Ukraine has led to an increased possibility of using nuclear weapons. The use of nuclear weapons during the bombing of the Japanese cities of Hiroshima and Nagasaki in August 1945 led to severe injuries and death of thousands of people, burns, mechanical trauma. Ionizing radiation lesions were new and specific, causing significant difficulties in the diagnosis and management of this pathology. Since then, there have been a number of accidents at nuclear power plants, the largest of which were the accidents at the Chernobyl and the Fukushima. During this time, the concepts of acute and chronic radiation syndromes were introduced into medical practice, and methods for treating these diseases were developed. Today, in connection with the threat of the use of a “dirty bomb” in Ukraine, as well as with the increasing likelihood of using tactical nuclear weapons, there was a need to form certain skills and concepts of actions in case of injuries from ionizing radiation among doctors and paramedical personnel.

Objective. To evaluate the prevalence of functional and anatomical changes in the lower extremities of pregnant women and discuss their possible causes and current therapeutic recommendations. Patients and methods. To assess changes in the lower extremities, 100 pregnant women at 38.5±1.3 weeks of gestation age were consecutively enrolled in an individual direct questionnaire. Patients’ ages ranged from 19 to 43 years (mean 31.4±5.3). The number of previous pregnancies and labours were 2.4±1.5 and 1.8±1.2 respectively. The demographic part of the questionnaire included information on age, height, body weight and shoe size before pregnancy and antepartum, medical and obstetric history and physical activity. The clinical section of the original questionnaire contained sections related to the assessment of skin, vascular, neurological and musculoskeletal disorders. Results. During pregnancy, there was an increase in women’s body weight from 66.6±14.8 kg to 78.8±14.6 kg and an increase in casual shoe size by 0.3 cm from 37.9±1.3 to 38.2±1.2 (in 27% of observations). More than half (57%) of study participants described their level of daily physical activity as moderate. The study showed that 85% of pregnant women reported functional or anatomical changes in the lower extremities, which included dermatological changes in 53%, vascular changes in 49%, peripheral nerves changes in 22%, and musculoskeletal changes in 69%. Conclusion. The gestational period is characterised by significant endocrine, immunological and metabolic changes of the pregnant woman, which provokes a range of both physiological and pathological conditions. Establishing the prevalence of lower limb symptoms and syndromes will provide the basis for developing an effective system of medical prevention and treatment of undesirable lower extremities effects.

The article describes the clinical manifestations and their causes in the pathology of the small intestine in patients who complain of excessive bloating, recurrent abdominal pain syndrome, stool disorders with a tendency to relaxation. Such patients repeatedly return to the doctor. The evidence of a decrease in the activity of disaccharidases in this cohort of patients is presented. The emphasis is placed on the need to study the nutritional history, to identify products that provoke a violation of membrane digestion. The classification of carbohydrates with indication of products containing them is given. The essence of repeated and persistent clinical manifestations due to impaired membrane digestion and absorption of carbohydrates in the small intestine is explained, which leads to their appearance in the large intestine in different volumes, which is accompanied by the splitting of carbohydrates with the formation of gases. On the one hand, this is a normal process, but when it gets out of control, the patient gets to the doctor. The essence of a carbohydrate–restricted diet is described - this is the low FODMAP diet and its decoding. The products containing oligosaccharides are indicated, which are capable of being cleaved by the enzyme alpha-galactosidase, which is absent in the human body, but is present in the microflora of the large intestine. Advice is given on limiting the intake of such products, both in terms of the frequency of intake and the volume of portions containing them, in order to avoid excessive amounts of intestinal gases, the development of a clinically painful condition. A thorough study of the nutritional history and the necessary correction of eating behavior is the main idea of this article, dedicated to the same type of clinical picture with varying degrees of manifestations of its symptoms.

Abstract. Ozone depletion over the polar regions is monitored each year by satellite and ground-based instruments. In this study, the vortex-averaged ozone loss over the last three decades is evaluated for both polar regions using the passive ozone tracer of the chemical transport model TOMCAT/SLIMCAT and total ozone observations from Système d'Analyse par Observation Zénithale (SAOZ) ground-based instruments and Multi-Sensor Reanalysis (MSR2). The passive tracer method allows us to determine the evolution of the daily rate of column ozone destruction, and the magnitude of the cumulative loss at the end of the winter. Three metrics are used to estimate the linear trend since 2000 and to assess the current situation of ozone recovery over both polar regions: 1) The maximum ozone loss at the end of the winter; 2) the onset day of ozone loss at a specific threshold and 3) the ozone loss residuals computed from the differences between annual ozone loss and ozone loss values regressed with respect to sunlit volume of polar stratospheric clouds (VPSC). This latter metric is based on linear and parabolic regressions for ozone loss in the Northern and Southern Hemispheres, respectively. In the Antarctic, metrics 1, and 3, yield trends of -2.3 and -1.8 % dec-1 for the 2000–2021 period, significant at 1 and 2 standard error (σ), respectively. For metric 2, various thresholds were considered, all of them showing a time delay for when they are reached. The trends are significant at the 2σ level and vary from 3.5 to 4.2 day dec-1 between the various thresholds. In the Arctic, metric 1 exhibits large interannual variability and no significant trend is detected; this result is highly influenced by the record ozone losses in 2011 and 2020. Metric 2 is not applied in the Northern Hemisphere due to the difficulty of finding a threshold value in a consistent number of winters. Metric 3 shows a negative trend in Arctic ozone loss residuals of -1.7 ±1 % dec-1, significant at 1σ level. This is therefore the first quantitative detection of ozone recovery in the Arctic springtime lower stratosphere.

Abstract. Glacial erosion creates diagnostic landscapes and vast amounts of sediment. Yet, knowledge about the rate by which glaciers erode and sculpt bedrock and the proportion of quarried (plucked) versus abraded material is limited. To address this, we quantify subglacial erosion rates and constrain the ratio of quarrying to abrasion during the 19th/20th century overriding of a bedrock surface fronting Jakobshavn Isbræ, Greenland, by combining 10Be analyses, a digital terrain model, and field observations. Cosmogenic 10Be measurements along a 1.2-m-tall quarried bedrock step reveal a triangular wedge of quarried rock. Using individual 10Be measurements from abraded surfaces across the study area, we derive an average abrasion rate of 0.13±0.08 mm yr-1. By applying this analysis across a ~1.33 km2 study area, we estimate that the Greenland Ice Sheet quarried 378±45 m3 and abraded 322±204 m3 of material at this site. These values result in an average total erosion rate of 0.26±0.16 mm yr-1 with abrasion and quarrying contributing in roughly equal proportions within uncertainty. Additional cosmogenic 10Be analysis and surface texture mapping indicate that many lee steps are relict from the prior glaciation and were not re-quarried during the recent overriding event. These new observations of glacier erosion in a recently exposed landscape provide one of the first direct measurements of quarrying rates and indicate that quarrying accounts for roughly half of total glacial erosion in representative continental shield lithologies.
Probabilistic Hydrological Estimation of LandSlides (PHELS): global ensemble landslide hazard modelling
Authors: Felsberg Anne , Heyvaert Zdenko , Poesen Jean , Stanley Thomas , De Lannoy Gabriëlle J. M.
Published: May 2023

Abstract. In this study we present a model for the global Probabilistic Hydrological Estimation of LandSlides (PHELS). PHELS estimates the daily hazard of hydrologically-triggered landslides at a coarse spatial resolution of 36 km, by combining landslide susceptibility (LSS) and (percentiles of) hydrological variable(s). The latter include daily rainfall, a 7-day antecedent rainfall index (ARI7) or root-zone soil moisture content (rzmc) as hydrological predictor variables, or the combination of rainfall and rzmc. The hazard estimates with any of these predictor variables have areas under the Receiver Operation Characteristic curve (AUC) above 0.68. The best performance was found with combined rainfall and rzmc predictors (AUC = 0.79), which resulted in the least missed alarms (especially during spring) and false alarms. Furthermore, PHELS provides hazard uncertainty estimates by generating ensemble simulations based on repeated sampling of LSS and the hydrological predictor variables. The estimated hazard uncertainty follows the behaviour of the input variable uncertainties, is about 13.6 % of the estimated hazard value on average across the globe and in time, and smallest for very low and very high hazard values.

IMPACT OF VISUAL MODALITIES IN MULTIMODAL PERSONALITY AND AFFECTIVE COMPUTING
Authors: Ryumina E. V. , Karpov A. A.
Published: May 2023

Abstract. Personality and affective computing techniques play a significant role for better understanding of human’s behavior and intentions. Such techniques can be applied in practice in recommendation systems, healthcare, education, and job applicant screening. In this paper, we propose a novel multimodal approach to personality traits assessment that leverages affective features of human’s voice and face, as well as recent advances in the deep learning. We present a new mid-level modality fusion strategy that is based on a cross-modal attention mechanism with summarizing functionals. In contrast to other state-of-the-art approaches, we not only analyze a visual scene, but specifically process human’s upper body (selfie) and a scene background. Our experiments show that the Extroversion personality trait is better estimated by fusing visual scene, face, and audio (voice) modalities, while the Conscientiousness and Agreeableness traits are better assessed by fusing face, selfie, and audio modalities. Furthermore, our results show that utilizing the selfie modality outperforms the visual scene modality by more than 1% in terms of the Concordance Correlation Coefficient. Additionally, our approach based on processing three modalities (selfie, face, and audio) is on-par with other known state-of-the-art approaches that employ at least four modalities on the test set of the ChaLearn First Impressions V2 corpus.

Published: May 2023

Abstract. The safety and usability of infrastructures such as bridges, roads, and buildings must be monitored throughout their useful life. Traditional inspection methods are time-consuming and expensive, and innovative solutions using LiDAR-based techniques have developed. This study presents a semi-automatic method for detecting deteriorations on structural elements of a bridge using an integrated dataset of point clouds and radiometric information. The method involves using a Terrestrial Laser Scanner (TLS) to obtain high-resolution georeferenced point clouds of the bridge beams, which are then filtered to identify four classes of deteriorations. Six Machine Learning Classifiers are tested and compared using Overall Accuracy and F1-score metrics. The Random Forest emerged as the best-performing. It was then optimised by reducing the input features through an importance analysis and the accuracies measured. The results show promise and can be explored further on a larger dataset. The study aims to generalise the methodology to transfer it to actual cases.

Published: May 2023

Abstract. In this work, we proposed the hybrid non-convex regularizers for Poisson noise removal on medical images. The model is built by a combination of non-convex total variation and non-convex fractional total variation. The proposed model allows for avoiding the annoying staircase artifacts and obtaining the reconstruction results with sharp and neat edges during the noise removal process. For handling the minimization problem, we employ the alternating minimization method associated with the iteratively reweighted l1 algorithm. Numerical experiments illustrate the efficiency of the proposed model and corresponding algorithm.
BUILDING COMPONENT DEFORMATION TRACKING USING STRUCTURED LIGHT TECHNIQUE

Published: May 2023

Abstract. It is crucial to fully master the mechanical properties of building components for ensuring the safety of infrastructures during service. The laboratory deformation test is an important way to study the mechanical properties of building components. At present, there is still a lack of a combination of high-efficiency, high-accuracy, and low-cost measurement methods for laboratory deformation tests. To address the issue, a method is proposed to measure the deformation of building components by using the structured light technique in this paper. It is applied to the axial tensile test of the dog-bone specimen, and the 3D full-field displacement of the dog-bone specimen is obtained by calculating the established deformation tracking model. The experimental results demonstrate the deformation measurement accuracy is at the millimeter level and can meet the accuracy requirement in the laboratory. Furthermore, the results are consistent with the way of force and the deformation mechanism of the dog-bone specimen. This paper presents a novel method for the deformation measurement, which provides a reliable analysis basis for studying the mechanical properties of building components.

Published: May 2023

Abstract. The geomatics survey in the speleological field is one of the main activities that allows adding a scientific and informative value to the exploration of caves and is of fundamental importance to have a detailed knowledge of the hypogean cavity: only thanks to the reconstruction of the three-dimensional environment through range-based techniques, are possible orientation, inland navigation, lithological understanding, as well as a better organization of the exploration of the cave itself. This work describes the surveys made in the Bossea Cave, in the province of Cuneo (NW, Italy), considered among the most suggestive and geologically interesting in Europe because they also have an underground karst laboratory managed by the Scientific Station of Bossea (CAI of Cuneo) and the Department of Environment, Land, and Infrastructure Engineering (DIATI) of the Politecnico di Torino, with the collaboration of the department of Cuneo of ARPA Piemonte and the Radiation Section of ARPA Valle d'Aosta. The survey activities described below have been concentrated both on the internal environment and the mountainside above the cave. The work presents the analytical measuring principle of the portable rapid mapping system, and it is dedicated to analysing the performances of this instrument in terms of the accuracy and completeness of 3D point clouds generated. The proposed validation method follows the assessment of point cloud deviation between data based on SLAM technology and 3D point clouds obtained from a terrestrial LiDAR system. The trajectory covered about 1km, with a height difference of about 120m, reaching differences between SLAM and LiDAR sensors of about 15 cm in the plan and 22 cm on the vertical component.

Authors: Kalashnikova D. A. , Buryachenko V. V.
Published: May 2023

Abstract. The classification of natural objects in the wild is a popular task in the field of tourism and remote sensing. The key problem is the requirement for system performance in the absence of Internet access and a small amount of available resources, such as a mobile phone. In this regard, to solve the classification problem, it is required to use fairly simple neural networks and rely on a small amount of training data. The paper presents an image preprocessing method for object recognition in the the “Stolby National Park” in Krasnoyarsk city using a neural network. The approach involves applying a set of methods to expand the original training set. To analyze the effectiveness, several different neural networks based on MobileNET V2 are used, which makes it possible to compare test results on the original and extended data sets. We also evaluate the quality of objects identification on open datasets, such as Animals-10 and Landscape Pictures. The results of the experiments show the efficiency of data preprocessing, as well as the high performance of the modified neural network structure for the task of classifying natural objects in the environment.
Response of the sea surface temperature to heatwaves during the France 2022 meteorological summer

Published: May 2023

Abstract. The summer of 2022 was memorable and record-breaking, ranking as the second hottest summer in France since 1900, with a seasonal surface air temperature average of 22.7 ∘C. In particular, France experienced multiple record-breaking heatwaves during the meteorological summer. As the main heat reservoir of the Earth system, the oceans are at the forefront of events of this magnitude which enhance oceanic disturbances such as marine heatwaves (MHWs). In this study, we investigate the sea surface temperature (SST) of French maritime basins using remotely sensed measurements to track the response of surface waters to the atmospheric heatwaves and determine the intensity of such feedback. Beyond the direct relationship between SSTs and surface air temperatures, we explore the leading atmospheric parameters affecting the upper-layer ocean heat budget. Despite some gaps in data availability, the SSTs measured during the meteorological summer of 2022 were record-breaking, the mean SST was between 1.3 and 2.6 ∘C above the long-term average (1982–2011), and the studied areas experienced between 4 and 22 d where the basin-averaged SSTs exceeded the maximum recorded basin-averaged SSTs from 1982 to 2011. We found a significant SST response during heatwave periods with maximum temperatures measured locally at 30.8 ∘C in the north-western Mediterranean Sea. Our results show that in August 2022 (31 July to 13 August), France experienced above-average surface solar radiation correlated with below-average total cloud cover and negative wind speed anomalies. Our attribution analysis based on a simplified mixed-layer heat budget highlights the critical role of ocean–atmosphere fluxes in initiating abnormally warm SSTs, while ocean mixing plays a crucial role in the cessation of such periods. We find that the 2 m temperatures and specific humidity that are consistently linked to the advection of warm and moist air masses are key variables across all the studied regions. Our results reveal that the influence of wind on heatwaves is variable and of secondary importance. Moreover, we observe that the incident solar radiation has a significant effect only on the Bay of Biscay (BB) and the English Channel (EC) areas. Our study findings are consistent with previous research and demonstrate the vulnerability of the Mediterranean Sea to the increasing frequency of extreme weather events resulting from climate change. Furthermore, our investigation reveals that the recurring heatwave episodes during the summer of 2022 had an undeniable impact on all the surveyed maritime areas in France. Our study therefore provides valuable insights into the complex mechanisms underlying the ocean–atmosphere interaction and demonstrates the need for an efficient and sustainable operational system combining polar-orbiting and geostationary satellites to monitor the alterations that threaten the oceans in the context of climate change.
Correlation between the built environment and dockless bike-sharing trips connecting to urban metro stations

Published: May 2023

The influence of the built environment on dockless bike-sharing (DBS) trips connecting to urban metro stations has always been a significant problem for planners. However, the evidence for correlations between microscale built-environment factors and DBS-metro transfer trips remains inconclusive. To address this, a framework, augmented by big data, is formulated to analyze the correlation of built environment with DBS–metro transfer trips from the macroscopic and microscopic views, considering Beijing as a case study. The trip density and cycling speed are calculated based on 11,120,676 pieces of DBS data and then used to represent the characteristic of DBS-metro transfer trips in a multiple linear regression model. Furthermore, a novel method is proposed to determine the built-environment sampling area around a station by its corresponding DBS travel distances. Accordingly, 6 microscale built-environment factors are extracted from street-view images using deep learning and integrated into the analysis model, together with 14 macroscale built-environment factors and 8 potential influencing factors of socioeconomic attributes and metro station attributes. The results reveal the significant positive influence of greenery and presence of barriers on trip density and cycling speed. Additionally, presence of streetlights is found to be negatively correlated with both trip density and cycling speed. Presence of signals is also found to have an influence on DBS-metro transfer trips, but it only negatively impacts trip density.

This article is an effort to aid investors by drawing attention to select investment items. Grey Wolf Optimization (GWO), TOPSIS with Eigenvector, Market Capitalization, and the Equal Weighted Technique are the four main methods discussed in this paper. This study uses the KSE-30 Index as its sample size; however, because to a lack of data, only 26 businesses are chosen for analysis using 10 criteria. All four methods are implemented and weights are determined based on these criteria. These weights are then utilized in conjunction with MATLAB's in-built tools to construct a portfolio. Based on its ability to generate the greatest possible portfolio, GWO appears to be a powerful resource for affluent investors. Equal-weighted portfolios performed the worst, followed by the Eigenvector-TOPSIS technique, then Market Capitalization.

O hidromel, também conhecido como vinho de mel, é uma das bebidas alcoólicas mais antigas do mundo. Basicamente, é uma bebida fermentada feita com mel. Ou seja, é obtido por meio do processo de conversão dos açúcares presentes no mel em álcool. A bebida, hoje em dia, está no seu caminho para o apogeu, tanto que seu consumo só vem crescendo dia após dia no Brasil e no mundo. Com isso, cada vez mais se vê criatividade e inovação em sua formulação. Portanto, este trabalho teve como objetivo a realização de uma revisão bibliográfica de todos os aspectos que envolvem o hidromel, desde o cultivo do mel até a produção da bebida. Para isso foram utilizadas fontes confiáveis de pesquisa, como o Google Acadêmico e o Scielo e ainda, não foi restringido um período para as pesquisas. Desta maneira, percebeu-se o quão grandioso é o universo em que esta bebida está inserida, permitindo-se fazê-la de diversas maneiras, para diferentes paladares. Sendo assim, conclui-se que o hidromel é um tema que possui grande apelo econômico e que oferece um potencial interessante para o mercado alcoólico brasileiro e mundial.

O cozimento é etapa limitante da produção de açúcar. Nesta fase são formados os cristais de sacarose e os erros de condução pode levar a redução da produção e diminuir o esgotamento do mel. O objetivo da presente revisão foi verificar os controles atuais do processo de cozimento em batelada e contínuo. O cozimento pode ser realizado com produção de duas ou três massas e os controles são para determinar a correta nucleação e garantir o crescimento dos cristais, na zona metaestável de supersaturação. Ao término do cozimento, os cristais devem ter tamanho adequado e com menor variação possível e com baixa cor. Se destacam vários métodos para controle desse processo como componentes principais, sensores mais sensíveis, redes neurais, análise de imagem (fractais), uso do instrumento SeedMaster, construção de modelos com mínimo quadrados, EMSO e através da internet. As pesquisas continuam para que a operação se torne cada vez mais automatizada e com menor ocorrência de erros, incrementando assim a produção de açúcar.
Supporting Teacher Learning During Modeled Mathematics Instruction

Published: May 2023

Although modeling instruction has been identified as a productive professional development activity that coaches can use with teachers in their classrooms, coaches are provided with little guidance regarding how to support teacher learning as they model mathematics instruction. While previous research points to the importance of providing teachers with examples of high-quality instruction through the coach’s model, teachers may need additional support as instruction unfolds to make sense of what they are observing. As part of the current study, I partnered with one mathematics coach and explored how she explicitly sought to augment teacher learning while modeling mathematics instruction. Findings indicate that the coach leveraged three approaches: engaging the teacher in verbal asides during modeled instruction, providing the teacher with written asides in the scripted lesson plan, and scaffolding the observing teacher’s responsibilities. Implications are provided for research and practice.

With increasing awareness of clean energy globally, the automotive industry is starting to produce electric cars and motorcycles. In Indonesia, sales of electric motorcycles are growing slowly. This is due to several factors, for example the lack of consumer knowledge about electric vehicles, high prices, limited sales network, uneven access to electricity in Indonesia, and also design limitations. This study discusses the process of designing an electric motorcycle for city touring activities for fans of classic motorbikes and classic styles, especially in the city of Bandung. This research is motivated by the possibility that the majority of domestic electric motorcycle designs are still in the form of scooters or mopeds. It creates a vacuum in the market. The purpose of this study is to produce an electric motorcycle design with a classic image for city touring activities in the city of Bandung. The resulting design has a novelty value that is offered, namely the use of classic design elements on electric motorcycles, and applying new functions to motorcycle parts that were previously closely related to the internal combustion function of the motorcycle. The design objectives were achieved through an online literature study analysis process accompanied by interviews and proofing the feasibility of the designs produced using the Stuart Pugh design method. At the end of the process, a design is produced in the form of a final concept sketch and a 3D model of an electric motorcycle.
