The traditional image classifiers are not capable to verify if samples belong to specified classes due to several reasons: classifiers do not provide boundaries between in-class and out-of-class samples; although classifiers provide separation boundaries between known classes, classifiers" latent features tend to have high intra-class variance; classifiers often predict high probabilities for out-of-distribution samples; training classifiers on unbalanced data results in bias towards over-represented classes. The nature of the class verification problem requires a different loss function than the ubiquitous cross entropy loss in traditional classifiers: input to a class verification function includes a suggested class in addition to an image. As opposed to outlier detection, space is transformed to be not only separable, but discriminative between in-class and out-of-class inputs. In this paper, class verification based on a euclidean distance from the class centre is proposed and implemented. Class centres are learnt by training on a centre loss function. The method"s effectiveness is shown on a self-checkout image dataset of 194 food retail products. The results show that a two-fold loss function is not only useful to verify class, but does not degrade classification performance - thus, the same neural network is usable both for classification and verification.

A major problem with using automated classification systems is that if they are not engineered correctly and with fairness considerations, they could be detrimental to certain populations. Furthermore, while engineers have developed cutting-edge technologies for image classification, there is still a gap in the application of these models in human heritage collections, where data sets usually consist of low-quality pictures of people with diverse ethnicity, gender, and age. In this work, we evaluate three bias mitigation techniques using two state-of-the-art neural networks, Xception and EfficientNet, for gender classification. Moreover, we explore the use of transfer learning using a fair data set to overcome the training data scarcity. We evaluated the effectiveness of the bias mitigation pipeline on a cultural heritage collection of photographs from the 19th and 20th centuries, and we used the FairFace data set for the transfer learning experiments. After the evaluation, we found that transfer learning is a good technique that allows better performance when working with a small data set. Moreover, the fairest classifier was found to be accomplished using transfer learning, threshold change, re-weighting and image augmentation as bias mitigation methods.

This paper presents a framework and mobile video editing app for interactive artistic augmentation of human motion in videos. While creating motion effects with industry-standard software is time-intensive and requires expertise, and popular video effect apps have limited customization options, our approach enables a multitude of art-directable, highly customizable motion effects. We propose a graph-based video processing framework that uses mobile-optimized machine learning models for human segmentation and pose estimation to augment RGB video data, enabling the rendering and animation of content-adaptive graphical elements that highlight and emphasize motion. Our modular framework architecture enables effect designers to create diverse motion effects that include body pose-based effects such as glow stick or light trail effects, silhouette-based effects such as halos and outlines, and layer-based effects that provide depth perception and enable interaction with virtual objects.

Published: July 2023

Assessment of personnel exposure from various operations performed inside radioactive waste (RW) storage facilities is seen as an essential task under the safety assessment of such storage facilities. However, radiation scattered from the structures inside the premises of RW storage facilities is often not taken into account in the assessment of personnel exposure doses. Characteristics of the radiation field from RW containers have been calculated under a few studies. For example, the radiation fields were calculated based on some engineering approaches and the Monte Carlo method using specialized software. This paper focuses on the Monte Carlo calculations of the gamma radiation dose rate from a volumetric cylindrical source located in a RW storage facility. The study evaluates the contributions of scattered radiation from the walls, floor and ceiling of a storage premise to the absorbed dose also considering the case of a flooded floor. The paper compares the calculated radiation dose rates with those evaluated by integrating the source volume for axisymmetric geometries with no account taken of scattered radiation. The calculations show that depending on the distance from the source if no scattered radiation from all the wall, floor and ceiling structures of a storage facility is accounted for, the dose rate may be underestimated by up to two times.

Introduction. Capital construction of buildings and structures in the Republic of Iraq is one of the most important areas of production activity, it is the basis for the development of all sectors in the country’s economy. The modern construction complex of Iraq is constantly developing and improving, modern construction materials, technologies, methods of organization and management of construction are being introduced, which makes it possible to implement construction projects of almost unlimited complexity. However, in modern conditions that have been formed in the Republic of Iraq from the end of the 20th century to the present, a special problem has become the need for full and timely provision of construction with all types of resources, which, in the conditions of the Iraqi construction market, is an unsolved scientific and practical task, due to the high influence of negative factors different nature, thereby reducing the organizational and technological reliability of the construction of buildings. Materials and methods. To solve this problem, 7 stages of developing a system of indicators for the sustainable development of resource infrastructure, which will improve the organizational and technological reliability of construction in Iraq are proposed. In addition, a model for calculating generalized criteria for the organizational and technological reliability of construction was developed. To determine the significance of indicators of organizational and technological reliability, it is proposed to use the method of expert evaluation. Results.

Published: July 2023

Indoor climate parameters influence the productivity of animals and their physiological condition. Exceeding permissible concentrations of gases leads to animal diseases, loss of productivity, and the mortality of young cattle. Therefore, it is reasonable to predict the concentration of gas composition in the livestock houses. To determine and distribute harmful gases (ammonia, hydrogen sulphide, and carbon dioxide) in the livestock house, the authors performed the 3D modeling of a fragment of the farm in the SolidWorks 2020 software package. Parametric models of gas movement under different conditions were created and optimal measurement points of gas concentration in the livestock house were determined. The simulations made it possible to determine the direction of air flows and detect accumulations and clouds of gases. The maximum concentration of carbon dioxide was detected at 0.9m (an air speed of 0 m/sec) and at 1.3m (a speed of 0.75 m/sec). The highest concentration of hydrogen sulphide was found in the area bordering the ridge space (an air speed of 0 m/s) and at the level of 2.25 m (a speed of 2 m/s). The highest concentration of ammonia was observed under the roof and in the area under the ridge (an air speed of 2 m/s). It is recommended to install hydrogen sulphide and ammonia sensors under the ridge, while carbon dioxide, hydrogen sulphide and ammonia sensors – in the stall, carbon dioxide and hydrogen sulphide sensors – near the feed table. Concentrations should be measured at heights of 500, 1500, and 3000 mm. When the concentration of emitted gas increases and other conditions are equal, the concentration of gas in the cloud increases, but the structure of the cloud changes insignificantly. Parameter interrogation sensors should be installed in enclosed ventilated boxes in the same manner as in weather stations.

Published: July 2023

Creating comfortable conditions for animals ensures their longevity and high productivity. Artificial ventilation, which includes supply and exhaust systems and a control system, minimizes the influence of the human factor on maintaining the indoor air parameters. The proposed system of indoor air-conditioning for the loose cattle housing layout was developed based on the analysis of ventilation systems of livestock premises and studies proving the effectiveness of dehumidification in winter using a regenerative heat exchanger. The system for providing indoor air parameters was developed using the computer-aided design program “Compass” (CAD) of the “Askon” company. The developed system for providing indoor air parameters for keeping cattle includes an electrofilter and a coarse filter, fans, a plate heat exchanger, a turbodefector; temperature, humidity, and air flow velocity sensors, dust collectors, a pump, a tank with a disinfectant, and a mechanism for shutting down supply air and recirculated air. The use of a recuperative dehumidification system at low outdoor temperatures helps maintain the relative indoor humidity within the regulatory limits (75…40%) and reduce the concentration of carbon dioxide by 20…45%. To ensure these indoor air parameters without dehumidification, 200 kW of thermal power is needed to heat the supply air. The proposed combined energy-saving all-season climate control system provides monitoring of indoor air parameters and energy saving through the use of a turbo deflector, disinfects the ventilation air, dehumidifies the air in the cowshed in winter and cools in summer, and also partially removes dust from the air with an electromagnetic filter.

Published: July 2023

Study on the impact of investment risk-taking on the performance of small and medium enterprises (SMEs) are still inconsistent. This study provides novelty to the relationship between the two variables by adding moderating variables of information technology and religiosity. This study took a sample of 94 SME owners in Banyumas Regency. The results show that the influence of investment risk-taking and information technology has no significant results. The higher level of religiosity of the SME owners will be able to improve the company's performance. The moderating relationship between information technology and investment risk-taking shows significantly positive results. In contrast, the moderating effect of the religiosity variable will further reduce the effect of investment risk-taking on company performance.

Published: July 2023

According to the World Economic Forum (2020), around 32% of plastics (polymers) are inappropriately disposed in the environment, 40% in landfills, 14% are incinerated, 14% are sent for recycling, and only 2% of this fraction sent for recycling is recovered in durable products. These data demonstrate that even if potentially recyclable waste is sent to the Selective Collection, many are not recyclable due to the use of different types of polymeric materials with no market for recycling. This study aims to analyze which types of polymer packaging are currently sent via Selective Collection to Sorting Units, but which end up becoming waste and are sent for final disposal in landfills. For the development of the research, 32 types of polymeric material (plastics) were evaluated in order to identify whether or not they are commercialized in 37 Sorting Units in Porto Alegre and the Metropolitan Region. The results indicate that the resins with the lowest potential for recyclability were the types of polymeric resins: PET (1) of the tray type, PET (1) pigmented material, PP (5) of the bioriented polypropylene film type (BOPP), PS ( 6) single-use packaging such as cups, cutlery, plates, trays and coffee capsules, OTHERS (7) which are characterized by the mixture of more than one polymeric material, such as sachets, yerba mate packaging, coffee, animal feed, in addition to other types of materials such as acrylic.

A fibrilação atrial (FA) é a arritmia mais comum na população, além de responsável por 33% das internações por todas as arritmias, com maior incidência em idosos. Estudos que demonstram os efeitos crônicos do treinamento físico (TF) têm crescido nos últimos anos, indicando o importante papel do exercício físico no tratamento complementar dessa arritmia. O TF tem se mostrado eficaz em relação a ganhos em capacidade funcional, aspectos da estrutura e função cardíaca, força muscular, resposta autonômica e qualidade de vida de pessoas que vivem com FA. Evidências recentes também têm demonstrado benefícios do TF quando a FA está associada a insuficiência cardíaca (IC). Embora estejam claros os benefícios do TF nessa população, por outro lado, o excesso de tempo acumulado em esportes de resistência de alta intensidade possui efeito nocivo e tem sido associado a maiores chances de se desenvolver FA. É imprescindível que seja realizada com um cardiologista uma avaliação pré-participação em programas de exercícios físicos para que seja estabelecida a otimização clínica e medicamentosa, proporcionando segurança para a prescrição e supervisão do TF. Sendo assim, o objetivo deste suplemento é abordar evidências científicas dos benefícios do TF na fibrilação atrial.

Fibrilação atrial (FA) é uma das arritmias cardíacas mais prevalentes na população mundial e vem acompanhada de complicações graves, como acidente vascular cerebral (AVC). Como todos os indivíduos portadores de doença crônica, pacientes com FA também necessitam de um olhar multiprofissional e por isso os cuidados odontológicos precisam estar inseridos no plano de cuidado geral do paciente. Diante deste contexto, por meio de uma revisão integrativa da literatura, o objetivo deste artigo é descrever os cuidados odontológicos necessários em pacientes com FA. Através da busca nas diferentes bases de dados e do cruzamento dos descritores “Atrial Fibrillation” e “Dental Care”, 708 artigos foram encontrados no PubMed, Scopus e Embase. Ao final, conforme critérios de inclusão e exclusão, foram selecionados seis artigos para compor esta revisão. Os resultados foram categorizados e apresentados em uma tabela descritiva. A maioria dos estudos descreve a associação da doença periodontal e a FA. Portanto, ações preventivas, como orientação de higiene bucal recorrente e terapia periodontal de suporte (TPS), são necessárias nesta população a fim de evitar a periodontite, que pode ocasionar impacto negativo no controle da FA e na qualidade de vida dos pacientes. Além disso, orientações gerais também foram descritas a fim de orientar os cirurgiões-dentistas para o atendimento odontológico aos indivíduos com FA. Esta revisão integrativa trouxe informações relevantes para orientar cirurgiões-dentistas e cardiologistas no atendimento aos indivíduos com FA e proporcionar mais segurança no atendimento odontológico clínico e cirúrgico.

As doenças cardiovasculares são a principal causa de mortalidade ao redor do mundo, sendo também responsáveis por relevante carga de morbidade. Nas últimas décadas, evidências mostram diferenças entre homens e mulheres no que tange a fatores de risco clássicos para doença cardiovascular, sintomas à apresentação de eventos, exames complementares de estratificação de risco, além de tratamento e prognóstico. Além disso, a crescente identificação de fatores de risco cardiovascular inerentes ao gênero feminino (como síndrome dos ovários policísticos, eventos adversos gestacionais, menarca e me-nopausa precoces, terapia de reposição hormonal) e a falta de ferramentas de predição de risco cardiovascular que contemplem tal risco são desafios para o manejo dessas afecções tão frequentes. A abordagem e medidas de prevenção primária e secundária das doenças cardiovasculares na mulher requerem abordagens efetivas nas diversas esferas inerentes e não inerentes ao gênero. Neste artigo, abordamos as medidas para prevenção primária e secundária de doenças cardiovasculares em mulheres

Drug-resistant forms of epilepsy are an important medical and social problem.

Goal of the work. Evaluation of the probability of achieving remission after correction of therapy in patients with drug-resistant focal epilepsy.

Material and methods. The study included 309 patients divided into three heterogeneous groups: a group of patients with focal pharmacoresistant epilepsy; a group of patients with super refractory focal epilepsy; control group – patients who had not previously received treatment. The examination included history taking, clinical and neurological examination, routine EEG and/or EEG video monitoring, MRI of the brain, and analysis of medical records. Therapy was adjusted.

Results. After correction of therapy, remission in patients in Group 1 was achieved in 27.8% of patients, improvement – in 27.1%, no effect – in 45.1%; in Group 2, remission was achieved in 13.2% of patients, improvement – in 28.6%, no effect – in 58.2%; in Group 3, remission was achieved in 41.2% of patients, improvement – in 32.9%, no effect – in 25.9%. Negative prognostic factors did not show a significant correlation with the lack of effect of therapy.

Conclusion. After correction of therapy, remission was achieved in several patients with drug-resistant focal epilepsy, while negative prognostic factors do not exclude the possibility of achieving remission.

We conducted a systematic review of 23 original studies published from 2010 to 2022, which participated a total of 168 thousand people, including 48 thousand patients with chronic obstructive pulmonary disease (COPD) aged 45 to 93 years.

Results. The prevalence of cognitive impairment (CI) in patients with COPD varies from 6 to 63%. COPD patients have a higher risk of developing mild CI (HR from 1.1 to 1.9; OR from 1.4 to 2.4) and dementia (HR from 1.3 to 1.9; OR = 1.2). The risk of cognitive dysfunction increases along with a decrease in the values of forced expiratory volume in one second as a percentage of its expected value (FEV1%) (OR = 1.34), arterial oxygen partial pressure (PaO2) (OR = 5.45), oxygen saturation (SaO2) and an increase in the level of arterial carbon dioxide partial pressure (PaCO2). There is a significant direct relationship between FEV1% and Mini-Mental State Examination (MMSE) (p < 0.0001) and an inverse relationship between COPD severity and MMSE (p < 0.0001). The MMSE score is correlated with FEV1% (r = 0.46, p < 0.01) and PaO2 (r = 0.43, p < 0.05).

Conclusion. The available data confirm the association of COPD with an increased risk of occurrence and progression of CI. It is discussed that this is due to the unfavorable course of concomitant vascular and neurodegenerative diseases against the background of chronic hypoxia.

Kinesiotherapy is eff ective in the treatment of chronic nonspecific back pain (CNBP), but its eff ectiveness in tensiontype headache (TTH) is unclear. The effectiveness of kinesiotherapy in patients with CNBP and comorbid TTH has been little studied.

The aim of the study was to evaluate the effectiveness of kinesiotherapy in patients with CNBS and comorbid TTH. Patients and methods. 52 patients (22 men and 30 women, mean age 32.4 ± 7.5 years) with CNBP and combined TTH were included in the study. All patients received standard treatment, of which 28 patients received kinesiotherapy (Group 1) and 24 patients were included in the comparison group (Group 2). All patients used pain diaries. All patients were tested by using the Beck Anxiety Inventory, the Beck’s Depression Inventory, the Pain Catastrophization Scale, the Kinesiophobia Scale, the Oswestry Disability Index, the Roland–Morris Disability Questionnaire, the Headache Impact Test 6, numerical pain rating scale before treatment and 3, 6 months after treatment. Clinical effcacy was assessed by reducing the frequency and intensity of headache (by ≥ 50%), back pain (by ≥ 30%), and by increasing functional activity during the day (by ≥ 30%).

Results. At 6 months follow-up signifiantly more patients in group 1 than in group 2 achieved a clinical effect on TTH and CNBP: 78.5% (n = 22) compared to 41.7% (n = 10); OR (95% CI) = 1.99. In 9 patients (32%) of group 1, a complete remission of TTH and CNBP was noted, in group 2 there were no such patients. At 6 months follow-up group 1 showed a significant improvement (p < 0.05) in comparison with group 2 in terms of functional activity and emotional state.

Conclusion. Kinesiotherapy for CNBP and combined TTH is effective both for back pain and headache. It increases functional activity and improves the emotional state of patients.
Influence of the Bowtie Shaped Dimples on the Performance of Sliding Surfaces under Hydrodynamic Lubrication
Authors: Gangadia Hardik , Sheth Saurin
Published: July 2023

It covers the tribological behaviour of sliding surfaces, one of which has bowtie-shaped micro-dimples. Against the other fixed, textured wall, one wall is smooth and moving at a constant speed. For the formation of hydrodynamic pressure and tribological behaviour, the effects of bowtie-shaped dimples and orientated bowtie-shaped dimples have been compared with circular-shaped dimples. Additionally, the impact of sliding speed, dimple area density, and dimple depth on tribological behaviour was examined. The findings show that compared to a circular-shaped dimple, an atypical bowtie-shaped and orientated bowtie-shaped dimple generates a higher net hydrodynamic pressure in the fluid domain and offers improved stability between the sliding surfaces. It has been demonstrated that geometrical factors like dimple depth and area density as well as operational factors like sliding speed have a substantial impact on the hydrodynamic average pressure and tribological behaviour of sliding surfaces. The experimental results support the conclusions from the analysis and CFD.
Effect of basal friction on granular column collapse
Authors: LI Yucheng
Published: July 2023

The collapse behaviour of granular materials is influenced by many factors, such as aspect ratio and inter-particle friction. However, the specific impact of basal to grain friction on column collapse remains poorly understood. In this study, we systematically analyse the effect of basal friction on gravity-driven granular column collapse using a validated smoothed particle hydrodynamics (SPH) model. The results show that such the basal friction coefficient does influence run-out distance, final height, and deposit morphology. To predict the run-out distance, we propose a modified formula that incorporates the basal friction coefficient, considering two extreme cases, i.e., μ = 0 and +∞. Furthermore, the basal friction also exerts an influence on the final height, with higher friction coefficients resulting in greater final heights. As the friction coefficient increases, the aspect ratio corresponding to the maximum final height also increase. However, we observe a convergence of the effect of basal friction on the final height when μ > 0.5. Moreover, the competition mechanism between the initial column aspect ratio and basal friction coefficient reveals two transition zones between the three main deposit regimes (regime I, regime II, and regime III). This implies that the basal friction can influence the deposit regime. Our findings show the clear influence of basal friction on the collapse behaviour of granular materials and therefore should be carefully considered in future studies.

Doyle’s Two-Stage Approach to Free Will: A Biophysics for Real Choice?
Authors: Edwards Jonathan
Published: July 2023

Robert Doyle has argued that traditional difficulties associated with the concept of free will can be resolved by a two-stage approach, explored by several philosophers and scientists. Possibilities for action can be generated within the brain, more or less randomly, from which an ‘adequately determined’ choice can be made. A similar selective process is well worked out within immune cells, which may provide a useful model. A degree of randomness is pervasive in the physical world but living systems have evolved to both tame and exploit this aspect at the interface between fluid and solid phases. Random and systematically determined processes are used in combination. These cell biological considerations support the plausibility of the two-stage model and may help point to specific mechanisms but may also raise a question about ‘who’ is doing the choosing. Computer modelling may sharpen the focus of that question. It may also highlight a paradox – that ‘freedom’ may only exist as the flipside of limitations or constraints imposed by real world situations.
The privacy of personal status issues in legislation and the judiciary -Comparative study

The problems of life are many and differ from one person to another according to their sects and religions. The personal matters that pertain to the individual and his family or, to a greater extent, his clan, have a privacy that differs from others. For example, the marriage of a Muslim differs from the marriage of a non-Muslim in terms of its conditions and pillars, as well as with regard to matters of alimony, inheritance and other matters related to the person Himself Therefore, it is called personal status, as it concerns the condition of a person and not others, as it differs from commercial and criminal matters that all citizens are subject to its laws despite their different sects and religions. For all of this, we find that personal status has a specificity in which it differs from other statuses, which made it distinguished both legislatively and judicially due to its importance in building and cohesioning society.
