The article presents an overview of the current problem of comorbidity of schizophrenia and type 2 diabetes mellitus, the diseases that considerably limit the quality of life of patients and cause significant difficulties in patient management. We seek to clarify the current understanding of the factors contributing to the coexistence of these diseases, highlighting the potential role of genetic, epigenetic, and environmental factors in this regard. Particular attention is paid to the effect of antipsychotic drugs on glucose metabolism and the development of insulin resistance, which may contribute to the development of type 2 diabetes in patients with schizophrenia. Data from the most relevant studies on this issue are presented, and possible strategies for managing patients with these conditions are discussed. The purpose of this article is not only to collect and systematize the existing information on the comorbidity of schizophrenia and type 2 diabetes, but also to stimulate further research in this area to develop effective approaches to the diagnosis, treatment, and management of patients with these comorbid pathologies.

Brugada syndrome is still a current clinical problem. What do we know today - a literature review

Brugada syndrome (BrS) is a rare congenital arrhythmia syndrome. BrS is characterized by a tendency to syncope, ventricular arrhythmias and sudden cardiac death. These symptoms occur mainly at night and can occur spontaneously or as a result of provocation by, for example, fever, stress or medication. Based on the differences in electrocardiography, three types were distinguished. Genetic studies are being conducted, which have shown a significant defect of the SCN5A gene, which in turn leads to disturbances in the functioning of the sodium channel NaV1.5 has a negative impact on the course of depolarization of myocardial cells. Patients with symptoms of the disease are subjected to implantation of a cardioverter-defibrillator, which protects them against sudden death. Data was obtained from the PubMed and Google Scholar platforms.

Multi-Parameter Health Assessment of Jujube Trees Based on Unmanned Aerial Vehicle Hyperspectral Remote Sensing

To address the current difficult problem of scientifically assessing the health status of date palm trees due to a single parameter for date palm health assessment, an imperfect index system, and low precision. In this paper, using jujube trees in 224 regiment of the 14th division of Xinjiang Production and Construction Corps “Kunyu city” as the research object, we carried out the inversion study of various physicochemical parameters of jujube trees (canopy chlorophyll content, leaf area index (LAI), tree height, canopy area) using the unmanned aerial vehicle (UAV) hyperspectral imagery of jujube trees during the period of fruit expansion, and put forward a model for assessing the health of jujube trees based on multiple physicochemical parameters. First, we calculated six spectral indices for inversion of chlorophyll content and four spectral index for inversion of LAI, analyzed the spectral index with high correlation with chlorophyll content and LAI of jujube trees canopy, and constructed the inversion models of chlorophyll content and LAI. Second, the Mask R-CNN model was used to achieve jujube trees’ canopy segmentation and area extraction, and the segmented canopy was matched with the Canopy Height Model (CHM) for jujube trees’ height extraction. Finally, based on the four physicochemical parameters of inversion, we construct four jujube trees’ health assessment models, namely, Partial Least Squares Regression Analysis (PLSR), Random Forest (RF), Support Vector Machines (SVM), and Decision Tree (DT). The results showed that the R2 of the PLSR tree health assessment model constructed based on the multi-physical and chemical parameters of chlorophyll content, LAI, tree height, and canopy area was 0.853, and the RMSE was 0.3. Compared with the jujube trees’ health assessment models constructed by RF, SVM, and DT, the R2 increased by 0.127, 0.386, and 0.165, and the RMSE decreased by 0.04, 0.175, and 0.063, respectively. This paper can achieve rapid and accurate inversion of multi-physical and chemical parameters of jujube trees with the help of UAV hyperspectral images, and the PLSR model constructed based on multi-physical and chemical parameters can accurately assess the health status of jujube trees and provide a reference for a scientific and reasonable assessment of jujube trees’ health.

Convective heat transfer enhancement by corona discharge in a wire–cylinder electrostatic precipitator with the water-cooling system

Aiming at the current wet plume problem, we present a novel technique to integrate electrostatic precipitator (ESP) and heat exchanger in order to simultaneously increase heat exchange efficiency, collect water and control particle emission from flue gases. Unlike the conventional ESP, a lab-scale wire–cylinder type ESP with the collection electrode cooling by water is used for investigations in this paper. Our research indicates that the heat transfer coefficient of the ESP rises with reducing gaseous velocity, increasing applied voltage, corona current or gas temperature. The maximum improvement of the total heat transfer coefficient of 271% was achieved at 0.15 m/s, 80 °C and 16 kV of the negative discharge. Moreover, the presence of Particle matters can enhance the heat transfer coefficient by 9%–16%. The ionic wind, which is quantitatively expressed by electro-hydrodynamic number, plays a key role in modifying the gas flow patterns and consequently improving the heat exchange coefficient. For lowering the overall energy consumption, it is suggested that the ESP should be operated at a specific mode of low voltage and high current.

Research on the preparation and diffusion characteristics of coal seam bottom fracture grouting material based on solid waste synergy

Fracture in the top and bottom plates of the coal seams in the Lubei Mining Area of China have developed to communicate with the Austrian gray pressurized water, and the threat of water damage is extremely serious. The rapid development of China's domestic economy has led to an increasing amount of industrial solid waste, which seriously jeopardizes the safety of the ecological environment. Based on the current problem, the slag powder (S) and waste rubber particles (R) were used as the main material, supplemented by cement (C) reinforcement with alkali slag (AS) excitation, and the mine fissure grouting and sealing reinforcement material was developed. The effects of water-cement ratio and (S: R) mass fraction on the physical and chemical properties of the grouted rock mass were analyzed using indoor tests, and the optimal components were determined; secondly, three-dimensional slurry-water-rock flow-solid coupling two-phase seepage simulation was realized using COMSOL, which revealed the diffusion morphology of the solid-waste slurry, preliminarily verified the feasibility of the grouting diffusion inside the rock mass, and determined the diffusion rule of the solid-waste slurry concerning the grouting pressure. The results indicate that at a water-cement ratio of 0.7 and a mass fraction of (S: R) at (70%:30%), the slurry has a flow degree of 275 mm, a water precipitation rate of 7.4%, a 28d compressive strength of 6.9 MPa, and follows the Bingham rheological model, with good injectability. Moreover, the slurry diffuses in simulated fracture grouting in a similar pattern to ultrafine cement slurry, satisfying the reinforcement requirements of field grouting. The research content realizes the combination of mine water damage control and solid waste scale, which is critical to ensuring production safety and the mine's green sustainable development.

Thermal features of Darcy-Forchheimer on a micropolar fluid flow over a curved stretching surface with homogenous-heterogeneous reactions

The main focus of contemporary study is to explore the Darcy magnetized flow of a micropolar second-grade fluid by consideration of homogeneous-heterogeneous reactions over a curved stretching surface. The thermal aspects of the fluid flow are analyzed with the inclusion of joule heating and thermal radiation effects. Moreover, magnetic field is imposed normal to the surface and thermal stratification condition is considered on the boundary of surface. An appropriate transformation is used to convert the flow model into a set of ordinary differential equations, which are nonlinear in the nature. The numerical solutions of this nonlinear system of equations are obtained using the bvp4c technique on MATLAB. The velocity, temperature, concentration, and micro-rotation distribution variation for various parameter is shown graphically and with numerical data. The main finding in the current problem to see that that greater estimation of micropolar parameter improves the angular velocity of the fluid, whereas linear velocity of fluid declines for larger values of magnetic parameter because of the resistance effect take place due to magnetized flow. Furthermore, it seems that curvature parameter produces the improvement in the linear and angular velocity of the fluid.

Virtual Admittance Feedforward Compensation and Phase Correction for Average-Current-Mode-Controlled Totem-Pole PFC Converters

This paper explores a current distortion problem in totem-pole bridgeless power factor correction (PFC) converters with average current mode (ACM) control. With in-depth modeling for the current and voltage loops, it was found that the current distortion is caused by the limited current loop bandwidth and input filter capacitor. These factors lead to the presence of a susceptance component in the input admittance, which degrades the power factor (PF) and total harmonic distortion (THD) of the PFC converter. To solve this problem, this paper proposes virtual admittance feedforward compensation (VAFC) and phase correction methods to adjust the input admittance to pure conductance. The VAFC can generate virtual admittance that compensates for susceptance components in the input admittance, while phase correction can generate an equivalent current source that offsets the current in input capacitors. Furthermore, a phase lock loop (PLL) is introduced to realize the VAFC, which reduces the feedforward interference caused by input voltage sampling noise. Finally, an experimental prototype was built to verify the effectiveness of the proposed strategies. According to the test results, the proposed compensation strategy improves the PF by 1.23%, while reducing the THD by 2.52% and achieving a peak efficiency of 98.69%.

Analytical Solution of Hyperbolic Tangent Fluid's Peristaltic Flow in an Inclined Channel: Hall Effect's Impact

Aim: In our study, we investigated, based on the premise of a long wavelength, how Hall's theory affected the peristaltic pumping of a fluid with a hyperbolic tangent within an inclined planar channel, and how both affected each other.
 Study Design: Abstract, introduction, Statement, Analytical Solution, Results and Discussion, and conclusion.
 Methodology: The intra-uterine fluid motion with tiny particles in a non-pregnant uterus is one of the many applications of the current physical problem, and this fluid motion condition is crucial for analysing the motion of the embryo in a uterus. Perturbation-oriented numerical research has been carried out in the current study to characterise the properties of velocity and axial pressure gradient in an inclined channel under Hall effect on the peristaltic flow of a Hyperbolic tangent because of these real-world applications. Under low Reynolds number and long-wavelength approximations, the current physical model yields the governing two-dimensional coupled nonlinear flow equations. For different values of the physical parameters, a suitable equation for the stream function is derived, and a regular perturbation scheme is used to produce the numerical solutions in terms of pressure rise and velocity. Weissenberg number, power-law index, Hall parameter, Hartmann number, and amplitude ratio relationships are examined in graphs along with their effects on the axial pressure gradient and time-averaged volume flow rate. According to the findings of this study, whereas the axial pressure gradient and time-averaged flow rate in the pumping region enhance with rising values of the Weissenberg, Hartmann, Reynolds, angle of inclination, and amplitude ratio, they diminish with enhances in the power-law index, Hall parameter, and Froude number. Hyperbolic tangent fluid has been discovered to require less pumping than Newtonian fluid.

FRONT END LEARNING MANAGEMENT SYSTEM DEVELOPMENT USING THE NEXTJS FRAMEWORK

Learning media is currently widely used in the teaching and learning process. Technology and information are two things that cannot be separated from one another in the ever-evolving digital era. Likewise with the education sector which underwent a significant transformation. The Learning Management System is a software application for online learning that supports delivering material online, discussing with students, and controlling student performance. This technological advancement has made many tertiary institutions use web application-based information technology. The current problem is the lack of complete features and less interactive functions to support the Learning Management System. In addition, when the user wants to be more interactive in learning, the Learning Management System generally has a separate feature, which requires the user to switch platforms to use the feature. The development of this Learning Management System is expected to become a more interactive learning platform and have complete features compared to other systems. System analysis is done by describing a system as a whole into its component parts. This is intended to identify and evaluate problems that will later find weaknesses and strengths in the system. The method used in this study is the waterfall starting from making the design of the system to implementing the system that runs in a production environment. The results of this study have several features needed for in-person and online learning which generally do not exist in other Learning Management Systems such as video conferencing, docs & files, group chats, automatic check-ins.

The ASGLOS Study: A global survey on how predatory journals affect scientific practice.

Predatory journals and conferences are an emerging problem in scientific literature as they have financial motives, without guaranteeing scientific quality and exposure. The main objective of the ASGLOS project is to investigate the predatory e-email characteristics, management, and possible consequences and to analyse the extent of the current problem at each academic level. To collect the personal experiences of physicians' mailboxes on predatory publishing, a Google Form® survey was designed and disseminated from September 2021 to April 2022. A total of 978 responses were analysed from 58 countries around the world. A total of 64.8% of participants indicated the need for 3 or fewer emails to acquire a criticality view in distinguishing a real invitation from a spam, while 11.5% still have doubt regardless of how many emails they get. The AGLOS Study clearly highlights the problem of academic e-mail spam by predatory journals and conferences. Our findings signify the importance of providing academic career-oriented advice and organising training sessions to increase awareness of predatory publishing for those conducting scientific research.

Experience with agomelatine therapy for non-psychotic depression with a single and recurrent course

Therapy of depression is a current problem in psychiatry. Agomelatine is not inferior to other modern drugs in terms of antidepressant efficacy (response and remission rates) and is characterized by the best tolerability.Objective: to evaluate the efficacy and safety of agomelatine in the treatment of nonpsychotic depression with a single and recurrent course.Material and methods. Patients (n=37) with a current depressive episode (DE; F32 according to ICD-10), mean age 41.2±2.07 years, were studied. Clinical psychopathological and psychometric methods were used in the study (Hamilton Hospital Depression Scale – HAMD-17; Spielberger–Khanin Anxiety Self-Assessment Scale, Sheehan Anxiety Scale, Clinical Global Impression Scale – CGI-I). A single DE was diagnosed in 62.2% of patients, and recurrent depressive disorder in 37.8%. Stress-related onset of current DE was found in 56.8% of cases, autochthonous in 43.2%.Results. 94.6% of patients were responders, including 68.6% who went into remission. A statistically significant decrease in scores on the HAMD-17 scale was noted in the remission group from the 7th day of agomelatine therapy (p<0.05), in the responder group – from the 14th day of therapy (p<0.05). According to the Sheehan scale, a statistically significant decrease in scores was noted at the end of the first week of therapy (p<0.05), according to the Spielberger–Khanin scale – in the second week (p<0.05) in all patients. According to the CGI-I scale, the condition at the end of therapy improved in 57.1% of patients, significantly in 42.9%. Clinical predictors of therapeutic response in patients with remission included significantly higher frequency of a single DE (p<0.02), moderate severity of current depression (p<0.02), dizziness among autonomic disorders (p<0.01), a significantly lower representation of the melancholic type of depression (p<0.05), a symptom of a gloomy and pessimistic vision of the future (p<0.05), sleep disturbances (p<0.04), a factor of personal significance in the form of a threat in patients with stress-provoked onset of the current DE (p<0.05).Adverse events occurred in the first week of treatment with agomelatine in 14.3% of cases (nausea – 8.6%, headache and dizziness – 2.9% each), they were mild and did not require discontinuation of the drug. Two patients taking agomelatine at a dose of 50 mg discontinued the study: in one case persisted social phobia, increased fatigue, motor retardation, and persistent modern insomnia; in the other case – a pronounced senestoalgic syndrome with cerebral localization.Conclusion. Agomelatine therapy has been shown to be highly effective and well tolerated in nonpsychotic depression.

Social networks, disinformation and diplomacy: a dynamic model for a current problem

The potential of social networks for the circulation of disinformation as a strategy of diplomacy has been of great interest to the academic community, but the way in which it is propagated and modelled is still in its beginnings. This article aimed to simulate the propagation of disinformation in social networks derived from the diplomacy strategy, based on the elements of the system. The main research question that was opened up was how do the elements of disinformation derived from the social media diplomacy strategy interact to affect a susceptible population? For the design of the simulation model, system dynamics was used as the main technique in the re-search methodology in conjunction with statistical analysis. Five computational simulations were run for the adoption methods of susceptible and uninformed population, misinformation techniques and echo chamber. The model developed found that the diplomacy disinformation agent is able to spread its message efficiently through the bot outreach mechanism and only a part of the susceptible population unsubscribes to the disinformation agent’s account. Significant differences were identified in the absence of paid outreach, bots and trolls in the propagation of information, and in the variation in the timing of disinformation propagation. Consequently, the developed model allows the understanding of the problem of disinformation as a strategy of diplomacy from international rather than local dynamics, as well as the effects of the use of each element in the system.

Vanadium oxide thin film deposited on Si by atomic layer deposition for non-volatile resistive switching memory devices

Vanadium dioxide (VO2) is a representative metal–insulator-transition (MIT) material that undergoes a reversible phase transition at 68 °C, which is close to room temperature. This shows the bias-triggered volatile resistance changes driven by MIT so that many studies have been made to implant VO2 as selectors for solving the sneak current problem of resistive random-access memory (ReRAM). However, the non-volatile switching of VO2 for non-volatile memory (NVM) application has not been demonstrated yet but if realized, this is truly breakthrough for low power and ultrafast NVM application. Herein, we report a successful formation of multiphase vanadium oxide on Si wafer via atomic layer deposition followed by a post-deposition annealing (PDA) process and demonstrate its applicability as a NVM device. It was confirmed that the multiphase vanadium oxide has MIT-driven abrupt resistance switching (i.e., low- and high-resistance state) at ± 1.6 V due to increased oxygen vacancies responsible for non-volatile memory property. The alternating current (AC) endurance upto 30,000 cycles and charge retention upto 3,000 sec are achieved at 2ⅹ102 of LRS/HRS current ratio. As a result, it opens the possibility of application to next-generation memory devices by reliable non-volatile MIT switching scheme.

Combination of known methods of bone autoplasty in Hartofilakidis grade 2 dysplastic hip arthroplasty in a patient with severe associated pathology

Introduction. Hip dysplasia is a current problem that requires a special approach for surgical treatment. The Crowe and Hartofilakidis classifications, which include grade 3 and 4 dysplasia respectively, are widely used. There are various methods for increasing the surface of the acetabulum: osteoclase of the medial wall, grafting with volumetric bone grafts and impaction grafting with bone chips. There are no definite recommendations that prescribe the surgical technique in any given clinical and radiological case. Therefore, the choice of acetabular grafting is individual and variable for each patient with hip dysplasia.The aim of the work was to evaluate the treatment of patients with stage 3 coxarthrosis combined with Hartofilakidis dysplasia degree I−II after total hip replacement using bone autoplasty with crumb and/or bone graft volume from the resected femoral head, using the patient with haemophilia and concomitant pathology of the musculoskeletal system as an example.Materials and Methods. Patient with Hartofilakidis hip dysplasia grade II with a history of right hip arthroplasty, haemophilia, multiple soft tissue mobilisations associated with joint contractures of the upper and lower extremities. Harris Scale score − 19.Results. Endoprosthesis of the left hip joint with combined acetabular roof plasty with a femoral head graft and bone shavings was performed. Six months later, the patient had increased range of motion, improved the biological axis of the limb, and residual shortening − 1.4 cm (due to deforming knee arthrosis). The prosthesis is stable. The method of plastic grafting with a bone graft showed a 100 % survival rate of the endoprosthesis, a decrease in pain and an increase in the function of the joint.Discussion. In this study, patients were followed up for five years. In similar studies, the time range was 10 years, at which point the survival rate of the arthroplasty decreased. The present case showed a good result because of its complexity due to concomitant pathology. In order to draw accurate conclusions, more such surgeries and follow-ups over a period of 10 years should be performed.Conclusion. Bone grafting makes it possible to effectively replace acetabular defects without excessive medialisation and to improve the degree of prosthetic coverage while preserving the native bone mass.
