Целью представленного исследования явилось определение места и роли сексуальных расстройств у представителей разного пола и возраста в развитии фоновой для церебрального инсульта патологии и формировании клинической картины острого периода инсульта и его последствий. Детально рассматривали вопросы интимной жизни 111 пациентов (58 мужчин и 53 женщины) в предшествовавшие инсульту периоды и определяли возможные связи с клиническими особенностями острого периода инсульта. У 77 из этих 111 пациентов изучали динамику сексуальных нарушений в связи с особенностями функционального дефекта, сформировавшегося спустя 3-24 мес после перенесенного инсульта. Выявлено, что снижение сексуальной активности до инсульта имеет, наряду с возрастом, отчетливое значение в развитии фоновой для инсульта патологии и в формировании последствий инсульта. У лиц пожилого возраста наиболее тяжелые функциональные последствия инсульта сформировались в 8,3 % при наличии нормальных сексуальных отношений в предшествовавший инсульту период и в 27,6 % при отсутствии таковых. Негативная динамика сексуальной активности после перенесенного инсульта выявлена в 46,8 % наблюдений, в основном у представителей пожилого возраста, и связана у женщин с наличием и выраженностью неврологического дефицита, у мужчин с присутствием церебральных атрофических изменений.

The purpose of this study was to determine the place and role of sexual disorders in representatives of different sexes and ages in the development of background for cerebral stroke pathology and the formation of the clinical picture of acute stroke period and its consequences. Questions of intimate life of 111 patients (58 men and 53 women) in the periods preceding a stroke were considered in detail and possible connections with clinical features of an acute period of in-Soult were defined. In 77 of these 111 patients, we studied the dynamics of sexual disorders in connection with the features of a functional defect that formed 3-24 months after a stroke. It was revealed that the decrease in sexual activity before the stroke has a distinct significance along with age in the development of background for insulin pathology and in the formation of the consequences of stroke. In the elderly, the most severe functional consequences of stroke were formed in 8,3 % in the presence of normal sexual relations in the period preceding the stroke and in 27,6 % in the absence of such. Negative dynamics of sexual activity after a stroke was detected in 46,8 % of cases, mainly among the elderly, and is associated in women with the presence and severity of neurological deficits, in men-with the presence of cerebral atrophic changes.

Работа основана на результатах ретроспективного анализа медицинской документации 56 пациентов с черепно-мозговой травмой, осложненной острой субдуральной гематомой объемом 60-100 см3. Пациенты были разделены на две группы по возрасту: 1-я 29 пациентов 22-29 лет; 2-я 27 пациентов 61-69 лет. Степень нарушения сознания у пострадавших при поступлении в клинику оценивали по шкале Глазго, эффективность проводимого лечения при выписке пациентов из стационара проводили по шкале Рэнкина, оценивая степень независимости и инвалидизации. У пациентов пожилого возраста выявлено более тяжелое состояние при поступлении в клинику. При выписке из стационара оценка степени независимости и инвалидизации по шкале Рэнкина выявила статистически значимое преобладание баллов в группе пациентов пожилого возраста (p<0,01), что говорит о менее эффективном их лечении в сравнении с пострадавшими молодого возраста. Результаты данного исследования могут послужить основой для разработки дополнительных рекомендаций в амбулаторной практике для ухода и попечения пациентов старшей возрастной группы и персонифицированному подходу к пострадавшим нейрохирургического профиля с учетом их возраста.

The work is based on the results of a retrospective analysis of the medical records of 56 patients with traumatic brain injury complicated by acute subdural hematoma with a volume of 60-100 cm3. The patients were divided into 2 groups according to their age: the 1st group included 29 patients aged 22-29 years, the 2nd group consisted of 27 patients aged 61-69 years. The degree of impaired consciousness in the victims at admission to the clinic was evaluated on the Glasgow scale, the effectiveness of the treatment at discharge from the hospital was performed on the Rankin scale, assessing the degree of independence and disability. Elderly patients were found to have a more severe condition upon admission to the clinic. Upon discharge from the hospital, the assessment of the degree of independence and disability on the Rankin scale revealed a statistically significant predominance of scores in the group of elderly patients ( p <0,01), which indicates less effective treatment in comparison with young patients. The results of this study can serve as a basis for the development of additional recommendations in outpatient practice for the care and care of patients in the older age group and a personalized approach to neurosurgical patients taking into account their age.

Characterization of AlGaN/GaN high electron mobility transistors on GaN substrates with different thicknesses of GaN channel and buffer layers using side-gate modulation
Authors: Villamin Maria Emma , Iwata Naotaka
Published: August 2021

AlGaN/GaN high electron mobility transistors (HEMTs) on GaN substrates with different thicknesses of GaN channel and C-doped buffer layers were fabricated and characterized with conventional DC and side-gate (SG) measurements. In SG measurement, drain current (I
D) was measured while SG bias (V
SG) was applied through a separate SG contact that surrounds the device active region. Whereas all HEMTs have comparable DC measurement results (∼500 mA mm−1
I
D, −2 V threshold voltage and ∼130 mS mm−1 transconductance), SG measurements show drastically different performances among the samples. Comparing HEMTs with and without C-doped buffer layer, results demonstrate that HEMT with doped buffer was stable against SG modulation until −15 V V
SG, whereas the HEMT without doped buffer was modulated near 0 V, and hence unstable against SG bias. Comparing HEMTs different channel thicknesses, the HEMT with a thicker 900 nm channel was more resistant to SG modulation than the HEMT with a thinner 100 nm channel. Therefore, these results highlight the importance of buffer doping and channel thickness to buffer stability.

Published: August 2021

We developed plastic scintillators loaded with perovskite quantum dots (QDs) to enhance the detection efficiency for high-energy photons such as X-rays and gamma rays. QDs with different emission wavelengths were loaded onto plastic scintillators at 5 wt%. The emission from the QDs only was observed in the radioluminescence spectra under X-ray irradiation. The photoluminescence decay behavior indicates that the absorption of the QD emission by the QDs themselves (self-absorption) results in long decay components, which were also observed in the scintillation decay. The detection efficiency for 67.4 keV X-rays was successfully enhanced by loading, although the scintillation light yield was reduced.

A generalized procedure of decoupled pulse width modulation (DCPWM) based on Method called Direct Torque Control (DTC) for Open Ended Winding Induction motor drive (OEWIM) is anticipated in this paper. This drive topology uses two isolated dc sources with equal magnitudes, feeding two standard two level three-phase inverters. To overcome the complexity in classical space vector pulse width modulation (SVPWM) algorithm, a simple generalized approach is presented in this research by using the phase voltages. With this procedure, various PWM algorithms can be generated by varying a constant value. The dual inverters are operating independently with half of the switching frequency. To show the usefulness of proposed PWM fed DTC drive, simulation results analysis has been carried out by using MATLAB and results obtained.

Biometrics systems are mostly used to establish an automated way for validating or recognising a living or nonliving person's identity based on physiological and behavioural features. Now a day’s biometric system has become trend in personal identification for security purpose in various fields like online banking, e-payment, organizations, institutions and so on. Face biometric is the second largest biometric trait used for unique identification while fingerprint is being the first. But face recognition systems are susceptible to spoof attacks made by nonreal faces mainly known as masquerade attack. The masquerade attack is performed using authorized users’ artifact biometric data that may be artifact facial masks, photo or iris photo or any latex finger. This type of attack in Liveness detection has become counter problem in the today's world. To prevent such spoofing attack, we proposed Liveness detection of face by considering the countermeasures and texture analysis of face and also a hybrid approach which combine both passive and active liveness detection is used. Our proposed approach achieves accuracy of 99.33 percentage for face anti-spoofing detection. Also we performed active face spoofing by providing several task (turn face left, turn face right, blink eye, etc) that performed by user on live camera for liveness detection.

As software systems evolve, there is a growing concern on how to manage and maintain a large codebase and fully understand all the modules present in it. Developers spend a significant amount of time analyzing dependencies before making any changes into codebases. Therefore, there is a growing need for applications which can easily make developers comprehend dependencies in large codebases. These applications must be able to analyze large codebases and must have the ability to identify all the dependencies, so that new developers can easily analyze the codebase and start making changes in short periods of time. Static analysis provides a means of analyzing dependencies in large codebases and is an important part of software development lifecycle. Static analysis has been proven to be extremely useful over the years in their ability to comprehend large codebases. Out of the many static analysis methods, this paper focuses on static function call graph (SFCG) which represents dependencies between functions in the form of a graph. This paper illustrates the feasibility of many tools which generate SFCG and locks in on Doxygen which is extremely reliant for large codebases. The paper also discusses the optimizations, issues and its corresponding solutions for Doxygen. Finally, this paper presents a way of representing SFCG which is easier to comprehend for developers.

Salah satu yang harus diperhatikan dalam budidaya udang vannamei adalah kualitas air. Kualitas air ini harus dicek secara berkala karena akan berpengaruh kepada kelulushidupan udang. Parameter-parameter yang mempengaruhi kualitas air tambak udang vannamei adalah keasaman (pH), Oksigen terlarut (DO), Salinitas (TDS), suhu air, ketinggian air, dan kekeruhan air. Data kualitas air tambak udang dapat dikirimkan secara wireless dan sensor dapat disebar keseluruh tambak dengan jenis sensor yang berbeda pada setiap nodenya. Node sensor akan mengirimkan hasil pembacaan dari masing masing sensor yang terpasang ke gateway dan kemudian dikirimkan dan diolah di server. Hal ini memudahkan pemilik tambak dalam mengakses data sensor dikarenakan udang vannamei sensitif terhadap perubahan kualitas air sehingga dengan ini bisa dilakukan tanggapan ketika data kualitas air tambak udang vannamei berubah. Untuk mengatasi hal tersebut maka dikembangkan alat WSN dengan plug dan play sensor. Alat WSN terdiri dari integrasi sensor keasaman (pH), Oksigen terlarut (DO), Salinitas (TDS), suhu air, ketinggian air, dan kekeruhan air (Turbidity) dengan topologi bintang. Hasil penelitian menunjukkan bahwa pada jarak 50 meter alat dapat mengirim data 250 byte ke server dalam rentang waktu dari 100 sampai 790 mikrodetik dengan protokol esp-now. Selanjutnya nilai kesalahan pembacaan sensor dalam rentang 0% - 4%.

In this paper, we report record DC and RF
performance in β-Ga2O3 High Electron Mobility Transistor (HEMT)
with field-plate T-gate using 2-D simulations. The T gate with head-length LHL of 180 nm and
foot-length LFL of 120 nm is used in the highly scaled device
with an aspect ratio (LG/tbarrier) of ~ 5. The proposed
device takes advantage of a highly polarized Aluminum Nitride (AlN) barrier
layer to achieve high Two-Dimensional Electron Gas (2DEG) density in the order
of 2.3 × 1013 cm-2, due to spontaneous as well as
piezoelectric polarization components. In the depletion mode operation, maximum
drain current ID,MAX of 1.32 A/mm, and relatively flat
transconductance characteristics with a maximum value of 0.32 S/mm are measured.
The device with source-drain distance LSD of 1.9 µm exhibits record
low specific-on resistance RON,sp of 0.136 mΩ-cm–2, and
off-state breakdown voltage of 403 V, which correspond to the record power
figure-of-merit (PFoM) of ~ 1194 MW/cm2. Additionally, current gain
cut-off frequency fT and maximum oscillation frequency fMAX
of 48 and 142 GHz are estimated. The obtained results show the potential of Ga2O3

Published: August 2021

Navigation in an unknown environment without any preexisting positioning infrastructure has always been hard for mobile robots. This paper presents a self-deployable ultra wideband UWB infrastructure by mobile agents, that permits a dynamic placement and runtime extension of UWB anchors infrastructure while the robot explores the new environment. We provide a detailed analysis of the uncertainty of the positioning system while the UWB infrastructure grows. Moreover, we developed a genetic algorithm that minimizes the deployment of new anchors, saving energy and resources on the mobile robot and maximizing the time of the mission. Although the presented approach is general for any class of mobile system, we run simulations and experiments with indoor drones. Results demonstrate that maximum positioning uncertainty is always controlled under the user's threshold, using the Geometric Dilution of Precision (GDoP).

Heterogeneous Graph Convolutional Networks for Android Malware Detection using Callback-Aware Caller-Callee Graphs
Authors: K V Vinayaka , C D Jaidhar
Published: August 2021

 The popularity of the Android Operating System in the smartphone market has given rise to lots of Android malware.
To accurately detect these malware, many of the existing works use machine learning and deep learning-based methods,
in which feature extraction methods were used to extract fixed-size feature vectors using the files present inside the Android Application Package (APK).
Recently, Graph Convolutional Network (GCN) based methods applied on the Function Call Graph (FCG) extracted from the APK are gaining momentum in Android malware detection,
as GCNs are effective at learning tasks on variable-sized graphs such as FCG, and FCG sufficiently captures the structure and behaviour of an APK.
However, the FCG lacks information about callback methods as the Android Application Programming Interface (API) is event-driven.
This paper proposes enhancing the FCG to eFCG (enhanced-FCG) using the callback information extracted using Android Framework Space Analysis to overcome this limitation.
Further, we add permission - API method relationships to the eFCG. The eFCG is reduced using node contraction based on the classes to get R-eFCG (Reduced eFCG) to improve the generalisation ability of the Android malware detection model.
The eFCG and R-eFCG are then given as the inputs to the Heterogeneous GCN models to determine whether the APK file from which they are extracted is malicious or not.
To test the effectiveness of eFCG and R-eFCG, we conducted an ablation study by removing their various components.
To determine the optimal neighbourhood size for GCN, we experimented with a varying number of GCN layers and found that the Android malware detection model using R-eFCG with all its components with four convolution layers achieved maximum accuracy of 96.28%.
Arterial Flow and Diameter-based Blood Pressure Models-an In-silico Comparison
Authors: Gonçalves Seabra Ana Carolina , Ferreira da Silva Alexandre , Stieglitz Thomas , Amado Rey Ana Belen
Published: August 2021

This paper investigates the best method for obtaining highly accurate blood pressure values in non-invasive measurements when using an ultrasound sensor. Deviations of the model should be less than 5 mmHg from the actual values. Different blood pressure models were analyzed and qualitatively compared. Relevant arterial parameters such as luminal area, flow velocity and pulse wave velocity, of 729 subjects were extracted from a computer simulated database and served as input parameters. Due to pulse wave variations through the arterial tree, such as viscoelasticity and arterial stiffness, the applied algorithms need to be specifically adapted to each arterial site. In-silico model comparison at different arterial sites were used to identify the parameters for individual equations that deduce the blood pressure at different arteries (carotid, brachial and radial). A linear model calibrated luminal area pulse wave to blood pressure and revealed to be most accurate model. The model was validated with a commercial pressure sensor in an ex-vivo experimental setup. The results showed an in-silico pulse pressure correlation of 0:978 and mean difference of (-2.134 ±2.477) mmHg at the radial artery and ex-vivo pressure correlation of 0:994 and mean difference of (0.554 ±2.315) mmHg.
A Positioning System Based on Low-Frequency Magnetic Fields

Published: August 2021

This paper describes the design and the realization of a low-frequency ac magnetic-field-based indoor positioning system (PS). The system operation is based on the principle of inductive coupling between wire loop antennas. Specifically, due to the characteristics of the ac artificially generated magnetic fields, the relation between the induced voltage and the distance is modeled with a linear behavior in a bilogarithmic scale when a configuration with coplanar, thus equally oriented, antennas is used. In this case, the distance between a transmitting antenna and a receiving one is estimated using measurements of the induced voltage in the latter. For a high operational range, the system makes use of resonant antennas tuned at the same nominal resonant frequency. The quality factors act as antenna gain increasing the amplitude of the induced voltage. The low-operating frequency is the key factor for improving robustness against nonline-of-sight (NLOS) conditions and environment influences with respect to other existing solutions. The realized prototype, which is implemented using off-the-shelf components, exhibits an average and maximum positioning error, respectively, lower than 0.3 and 0.9 m in an indoor environment over a large area of 15 m × 12 m in NLOS conditions. Similar performance is obtained in an outdoor environment over an area of 30 m × 14 m. Furthermore, the system does not require any type of synchronization between the nodes and can accommodate an arbitrary number of users without additional infrastructure.
Why Mixture?
Authors: Li Tiancheng
Published: August 2021

From the most known Gaussian mixture to the cutting-edge multi-Bernoulli mixture of various forms, mixture offers a fundamental means to deal with uncertainties, which has led to a variety of appealing applications in the state estimation realm based on a single sensor or a sensor network. Like noise is often used to model unknown system input, one may use various hypotheses to deal with the uncertain state space model or data association. Meanwhile, consensus may be sought over the cross-correlated sensors. These all drive a need for representing the probability distribution by a mixture of properly weighted component distributions, which fuse the information gained from different models/hypotheses or from different sensors. This technical note presents information-theoretical results which answer how the averaging/mixture approach makes sense and how the fusing weights should be designed.
Transformação do modo de produção agrícola e o papel das cestas de produtos orgânicos e agroecológicos
Authors: ADDOR Felipe , ALMEIDA Layssa Ramos Maia de
Published: August 2021

La forma de vida y producción en el campo brasileño está profundamente marcada por las consecuencias de la implementación de la Revolución Verde en la segunda mitad del siglo XX. A los trabajadores rurales se les expropiaron sus herramientas de trabajo, sus conocimientos y prácticas para dar cabida a un sistema que genera dependencia tanto en la producción, por la exigencia del uso de plaguicidas y semillas transgénicas, como en la comercialización, a través de la figura de intermediarios, dejando a esos lejos de los consumidores. En los últimos años han surgido varias experiencias que buscan construir alternativas a este modo de producción agrícola establecido, reforzando principalmente el papel de la agroecología y de otras formas de comercialización capaces de retomar el vínculo entre campo y ciudad. En este artículo, recordamos brevemente el proceso de desarrollo de estas condiciones en el campo brasileño, para luego discutir el papel de la estrategia de comercialización de cestas de productos orgánicos en Río de Janeiro como una forma de transformar el modelo de producción y comercialización de productos agrícolas. A partir de la creación de una tipología de estas organizaciones, buscamos resaltar el papel de quienes promueven, a través de este instrumento, la formación técnica y política de los trabajadores rurales en el sentido de transformar su realidad.

Monks at work in Eastern Mediterranean: Ideals and reality
Authors: Wipszycka Ewa
Published: August 2021

The main question that the present paper tries to answer is as fol- lows: since two discordant precepts concerning work were to be found in the New Testament, how did monks behave? One precept treated work as a duty, the other recommended not to care about one’s maintenance. The monks followed in their behaviour either the first or the second precept. As a result of disputes that took place in the fourth century the opinion prevailed that work was the better choice. It is important for us to find out when and under what circumstances that choice was done by the majority of the monastic movement in the East. It is also important to see what arguments were used by the monks of Late Antiquity in order to settle the conflict between the two discordant precepts. This conflict worried many and caused a renewal of a dispute that seemed to have been closed. Two ways of reasoning in favour of monastic work were generally used: monks might and should pray and work at the same time, satisfying both precepts; monks ought to work in order to be able to give alms, and this conferred to work a meaning that went beyond immediate usefulness. Praying and working at the same time was not always feasible in actual practice, but this did not bother authors of ascetic treatises.

Performance Reporting of APA :
Authors: Nesa Mst Sharifun
Published: August 2021

This paper focuses on implementing the Annual Performance Agreement (APA) in the land administration and examines the effectiveness of the performance measurement system of APA. One of the important objectives of this paper is to verify the accuracy and reliability of the performance information/data of the APA report through which the performance of the Upazila land office is measured. This verification is needed in order to observe whether the land administration is showing its actual performance achievement in the performance report to ensure accountability. In doing this, both primary and secondary data were collected from 9(nine) Upazila land offices and analysed. Research findings suggest that APA is not working well in land administration. This is indicated by the gap between reported performance and actual performance. It is also found that unethical practice of manipulating performance information is going on in the APA reporting. As a result, the very concept of accountability of the public managers is not ensured, and the lofty target of providing better service to the citizens is hampered. Moreover, because of not showing the actual performance to the principal (political leaders) through performance report, wrong evaluation of the performance of the Land Administration is made, and the low productivity of the service delivery is hidden. So, the government cannot come to know the problems or causes of the non-compliance of the agreed targets and take any favourable decision or allocate resources in favour of that land office to increase productivity and meet the public demand of service delivery. So, the problem of data/information manipulation in APA's performance report urgently needs to be addressed by adopting an appropriate policy.

In order to help offset continuing environmental degradation in the 21st century, humans will have to significantly alter their habits (Howard, 2000; Oskamp, 2000; Winter, 2000). These altered habits cannot consist of merely doing the right thing every now and then; rather, they must be consistent, persistent efforts to move away from inherently wasteful and damaging behaviours and to move towards conservation-oriented or environmentally responsible behaviours (ERB). This environmentally responsible behaviour requires continuous motivation and training. This rigorous motivation and training to whole society cannot be provided by the government alone. But this can be implemented by the organisations to enhance organisational culture and societal wellbeing. In this context current article investigates the factors influencing employee green behaviour in Rashtriya Ispat Nigam Ltd.

This article considers the relevance of medical tourism in Ukraine, reveals the very concept of medical tourism, its potential, popularity, and realities of implementation. The ideas of improving medical tourism and overcoming problems in their implementation are highlighted, as well as compared to the experience of foreign medical institutions. Based on the analysis of international experience, the most popular types of treatment and rehabilitation among medical tourists, as well as the main reasons for the huge gap in the cost of medical services in leading countries and countries with emerging markets are identified. The prospects of medical tourism development on the basis of state support are outlined and the solutions to various problems of this industry in the perspective for the future in Ukraine are suggested. It should be noted that the relatively low price compared to European countries is the biggest advantage of medical tourism in Ukraine. The cost of medical services in Ukraine in most cases is much lower than the cost of similar treatment in other countries. The ways to develop the medical tourism market to address economic, political, and social issues, reorganize all systems of rendering medical care, change the structure of medical education in Ukraine are offered. The following main tasks are defined: to improve the quality of domestic medical care and treatment efficiency; to improve the work of staff in providing quality services; to revise the legislative base of Ukraine, to develop the law "On Medical Tourism"; to develop the departmental regulatory framework for cooperation with foreign clients in medical institutions, primarily in the state and municipal domains; to promote Ukrainian medical tourism in the world.
Corporate social responsibility as the foundation of the development of tourism enterprises
Authors: Leshko Khrystyna S.
Published: August 2021

Nowadays the tourism industry contributes to the development of partnership relations between the state and private sector and helps to strengthen the international partnership. It promotes the development of regions and stimulates the cooperation between the tourism industry and public society. Implementation of social orientation of the tourism industry contributes to the use of partnership approach to clients, economic entities, public authorities and local governments, NGOs, and the staff of touristic companies. This way, corporate social responsibility is formed. The implementation of corporate social responsibility stipulates overcoming the legal standards of business. The companies try to establish relations with society and invest in its development, strengthen its reputation, and harmonize the “living environment”. Yet, socially responsible behavior stipulates the allocation of some part of financial resources to solve the tasks that are not directly related to gaining profits. A strive to prosper urges the companies to search for the balance between the need to invest in the social domain and possible economic results in the long run. Understanding the fact that corporate responsibility can be an important tool for competition, the companies actively include its principles in the corporate strategy. The paper examines the features of social responsibility implementation as the foundation for the development of a tourism company. The nature of social responsibility is analyzed and the components of corporate social policy are characterized. The system functions of entrepreneurial activity of touristic companies that impact the forming of corporate social responsibility are determined. Based on the defined function, the major directions of tourism entrepreneurship development are outlined. The scheme of corporate responsibility in the tourism business is constructed. The measures directed at the implementation of external and internal social responsibility of a tourism company are suggested.

In all sugar factories there is a need to store the white sugar produced for a longer or shorter period of time. With today‘s standard factory sizes, storage capacities of more than 100,000 t per factory are necessary. Large-capacity silos such as those built in various designs in the sugar factories are used for this purpose. In addition to an overview of the various silo designs, information on the conditioning and heating of the silos and the requirements for explosion protection are compiled.
