Published: October 2020

INTRODUCTION:
Vulvar cancer is uncommon and relatively rare. Vulvar cancers do not always go through the preinvasive stages before developing into invasive cancer. It represents 1-4% of malignancies of female genital tract. Most common among the valvar cancer is squamous cell carcinoma (90%). Less common is melanoma, basal cell carcinoma, Adenocarcinoma and sarcoma which account for 10%.
AIM:
To determine the prevalence among genital tract malignancies, histopathological pattern, Staging, modality of treatment and post operative complications of malignant lesion of vulva.
METHODS:
It is a Cross sectional study carried out in Madurai medical college. The medical records of all women with malignant lesion of vulve between January 2009 to September 2011 were reviewed. From the case record, the patient profile, complaints, associated medical complications were noted. The record of investigations, treatment modalities and postoperative complications were studied. The diagnosis was confirmed by biopsy and clinical staging was done and planned for treatment.
RESULTS:
10 cases of malignant lesions of vulva were noted during the period. Prevalence is about 0.8% of all genital tract malignancies. Age wise distribution reveals 60 % of our cases were above 60 years of age. 80% of our prevalence observed in postmenopausal women. Most patient had complaints of pruritis (100%), ulcer(70%), swelling(30%). Had associated medical complication of diabetic (40%), hypertensive (20%). Histopathologically the most predominant type is squamous cell carcinoma (60%), malignant melanoma (10%), basal cell carcinoma(10%), Baseloid squamous cell carcinoma(10%), Vulvar intraepithelial neoplasia (10%). Stage wise classification of squamous cell carcinoma –stage 0-12.5%, stage2- 37.5%, stage 3- 37.5%, stage 4 – 12.5%.

Isolation is recommended for corona positive patients and their contacts are advised home quarantine. This study was planned to assess the practices followed during home quarantine/ isolation for COVID-19 pandemic among urban population in Rohtak, Haryana.
A cross-sectional survey was conducted among 101 persons on home isolation or quarantine in urban field practice areas attached to the Department of Community Medicine of a tertiary care centre of Rohtak. A semi-structured interview schedule was used to obtain information from the participants through house to house visit. Data were analysed using Microsoft Excel version 2010 and Statistical Package for Social Sciences ver.24.
79.2% subjects on home quarantine/ isolation restricted their movement inside house. Face cover was used by 98% and correct hand washing technique was practised by 70.3% participants. Behaviour change communication activities need to be further strengthened to improve practices followed during home quarantine/ isolation.
It may be time to improve the neuron of artificial neural network
Authors: Liu Gang
Published: October 2020

Artificial neural networks (ANNs) have won
numerous contests in pattern recognition, machine learning, or artificial
intelligence in recent years. The neuron
of ANNs was designed by the stereotypical knowledge of biological neurons 70
years ago. Artificial Neuron is expressed as f(wx+b) or f(WX). This design
does not consider dendrites' information processing capacity. However, some recent studies show that biological dendrites participate in the
pre-calculation of input data. Concretely, biological dendrites play a role in
extracting the interaction information among inputs (features). Therefore, it
may be time to improve the neuron of ANNs. According to our previous studies
(DD), this paper adds the dendrites' function to artificial Neuron. The
dendrite function can be expressed as Wi,i-1Ai-1 ○ A0|1|2|...|i-1 . The generalized new neuron can be expressed as f(W(Wi,i-1Ai-1 ○
A0|1|2|...|i-1)).The simplified new neuron
be expressed as f(∑(WA ○ X)). After improving the neuron, there
are so many networks to try. This paper shows some basic architecture for
reference in the future.

Interesting things: (1) The computational
complexity of dendrite modules (Wi,i-1Ai-1 ○ Ai-1) connected in series is far lower than Horner's method. Will this
speed up the calculation of basic functions in computers? (2) The range of sight of animals has a
gradient, but the convolution layer does not have this characteristic. This
paper proposes receptive fields with a gradient. (3) The networks using Gang
neurons can delete traditional networks' Fully-connected Layer. In other words,
the Fully-connected Layers' parameters are assigned to a single neuron, which
reduces the parameters of a network for the same mapping capacity.

One important thing: ResDD can replace the current all ANNs' Neurons (ResDD modules+One Linear module)! ResDD has controllable precision for better generalization capability!

Published: October 2020

Karya Merdeka Village is very famous for its oil palm plantations. Nearly 27% of the population work as oil palm farm laborers. In irrigating the plantations, they use diesel fueled rice cookers. Based on field surveys, 1 liter of diesel can be used for 2 hours to drive the dompeng machine. Means that in a month, residents need 30 liters of diesel fuel. If 1 liter costs IDR 6000, farmers will incur a cost of IDR 180,000 per month. Of course this needs to be balanced with an idea / innovation to reduce the expenditure of farmers in supplying diesel to their dompeng machines. Therefore, the Balikpapan State Polytechnic Lecturer team of the Electrical Engineering Department contributed significantly to the Community Service Activities (PkM) held at the Karya Merdeka Kelurahan Office, Kutai Kertanegara Regency in socializing a technology that can recycle used cooking oil into biodiesel, through a process of mixing with methanol and NaOH. The method of making it is quite simple, namely used cooking oil at a temperature of 40 degrees. For the right results, use a digital thermostat. The dose is 1 liter of used cooking oil mixed with half a liter of methanol and 0.1 mg NaOH. Stir until evenly distributed and leave for 24 hours. The result is biodiesel (clear color) and glycerol (the precipitate). Biodiesel is one alternative energy source that is environmentally friendly and proven to be economical in its implementation. It has the same function as Soilar, which is able to drive generators and dompeng engines, but is 3 times more efficient than diesel, which is 1 liter of biodiesel equivalent to 3 liters of diesel. It means that biodiesel is three times more efficient than diesel.

Северо-Кавказский регион производит пятую часть зерна в России. Получать стабильные высокие урожаи озимой тритикале в этом регионе не позволяют частые засухи. Их вероятность составляет 25-50 %. Кроме того, почти ежегодно, во второй половине вегетации посевы озимых зерновых в той или иной степени испытывают отрицательное воздействие дефицита влаги. Основным условием преодоления отрицательного влияния неблагоприятных факторов среды является создание и внедрение в производство высокопродуктивных и адаптированных к местным условиям сортов. В статье приведены результаты лабораторных и полевых исследований селекционного материала озимой тритикале на засухоустойчивость и продуктивность. Определение устойчивости растений к дефициту влаги проводили по способности семян прорастать на высокоосмотических растворах сахарозы. Оценка засухоустойчивости в полевых условиях проводилась по продуктивности сортов, в разные по влагообеспеченности годы, с использованием различных статистических методов. По результатам проведенных исследований относительной засухоустойчивостью и стабильной продуктивностью характеризовались сортообразцы: Гренадо, Гор, ПРАГ 506. Рекомендуются наиболее информативные и объективные методы оценки селекционного материала на засухоустойчивость. К ним относятся: лабораторный метод проращивания семян на осмотических растворах сахарозы и прямой способ расчета засухоустойчивости по индексу продуктивности растений.

The North Caucasus region produces a fifth of the grain in Russia. Frequent droughts do not allow stable high yields of winter triticale in this region. Their probability is 25-50 %. In addition, almost every year in the second half of the growing season, winter grain crops experience a negative effect of moisture deficiency. The main condition for overcoming the negative impact of adverse environmental factors is the creation and introduction of highly productive and adapted to local conditions varieties into production. The article presents the results of laboratory and field studies of the breeding material of winter triticale for drought resistance and productivity. Determination of plant resistance to moisture deficiency was carried out by the ability of seeds to germinate on highly osmotic solutions of sucrose. Assessment of drought resistance in the field was carried out by the productivity of varieties, in different years of moisture availability, using various statistical methods. According to the results of studies, the relative drought resistance and stable productivity were characterized by the varieties: Grenado, Gor, PRAG 506. The most informative and objective methods for assessing breeding material for drought resistance are recommended. These include: the laboratory method of seed germination on osmotic solutions of sucrose and a direct method for calculating drought resistance by the plant productivity index.

The Coronavirus disease (COVID-19) pandemic continues to shut down colleges and universities including medical schools all over the world, thus pushing medical schools to seek e-learning to maintain continuity of curriculum. Although developed countries are comfortable learning through the internet, low-income countries like Nepal with limited experience in e-learning have used this lockdown as an opportunity to develop online classes. This crisis has clearly revealed the importance of e-learning in for medical educators in Nepal to disseminate knowledge beyond the restrictions of geography and other barriers.
DOES LOCATION AFFECT EMPLOYMENT? EVIDENCE FROM THE HIGH NORTH OF RUSSIA
Authors: GILTMAN Marina
Published: October 2020

Local labour markets within one country can be characterized by different outcomes because of their geographical and economic peculiarities. The unique features of the labour markets of the High North regions of Russia include compensative differentials and specific labour protection legislation together with the specific geographical characteristics. The aim of the paper is to investigate what peculiarities arise in employment as a result of location in the areas of the High North of Russia. Using aggregate regional data for the northern regions of Russia from 2005 to 2014 we estimated the dynamic fixed effects models for the number of employees and net migration. It was discovered that geographical characteristics affect employment in the High North of Russia more than wages. Labour supply exceeds labour demand in the northern regions of Russia because of strong positive wage elasticity of net migration. We can surmise that regulation of wages and migration should be a part of common economic policy in the High North regions of Russia.
RENTAL INCOME AND CAP RATES: A COMPARISON OF THE LISBON AND PORTO HOUSING MARKETS
Authors: MOREIRA António C. , TAVARES Fernando O. , PEREIRA Elisabeth T.
Published: October 2020

The goal of this article is to analyse the relationship between rental income and capitalisation rates when real estate value is assessed in parishes of the Lisbon and Porto municipalities. Based on housing market values in euros per square metre during the 2006-2009 period, the income approach was used to compare the two main types of apartments (i.e. B2, or two-bedroom, and B1, or one-bedroom) in Lisbon and Porto. We used the capital asset pricing model to calculate the risk measure. The cluster analysis was used to group the Lisbon and Porto parishes according to their rental income and capitalisation rates. Regressions were used to model both geographical markets. Clear differences were found between Porto and Lisbon, the results being more robust for the Porto municipality in regard to B2 apartments. Moreover, rental income is inversely proportional to capitalisation rates for B1 apartments for Porto parishes, which means that there is an initial overinvestment.
THE ROLE OF SOCIAL CAPITAL AND INTERPERSONAL RELATIONS IN THE ALLEVIATION OF EXTREME POVERTY AND SPATIAL SEGREGATION OF ROMANI PEOPLE IN SZEGED

Published: October 2020

Even more emphasis is set on social capital in understanding, analyzing and planning poverty alleviation measures and policies. However, our understanding of the role of social capital in alleviating extreme poverty, enhancing social mobility and fighting spatial segregation, is still inadequate. Within the present study, we aim to examine and understand (1) the mechanisms that relate to social capital in the case of the segregated urban underclass and (2) the potential interventions for poverty alleviation concerning social capital. In order to examine the dynamics of poverty alleviation measures related to social capital, special attention is paid to the experiences of a cooperative network aimed at creating artificial bridging capital through the introduction of interpersonal relations locally between the middle class and underclass, the patronage network, which was initiated within a broader participatory action research (PAR) process. Our results show that bonding ties and related specific norms as tools for everyday survival easily overwrite system integration efforts for poverty alleviation and social mobility with long-term and uncertain benefits for the segregated urban underclass. In order to overcome this failure, social institutions should place more emphasis on developing meaningful interpersonal relations with the underclass since these might be able to provide personalized help, facilitation, and approximation of perspectives - all being vital for poverty alleviation and social mobility.
URBANIZATION, MULTI-MORBIDITIES AND PREFERENCE FOR HEALTH CARE FACILITY: AN INSIGHT FROM RAJASTHAN, INDIA
Authors: JAIN Kshipra , AROKIASAMY Perianaygam
Published: October 2020

India experiences rapid pace of urbanization with increasing elderly population and changing disease profile creating new set of health care demands. The study made a novel attempt by exploring the prevalence of morbidities, multi-morbidities along with preferred healthcare facility substantiated by its reasons among the older adults aged 50+ living in urban Rajasthan based on a primary survey. The higher prevalence of single morbidity compared to multi-morbidity reflects the possibility of future healthcare needs. Poisson regression estimates identified the elderly belonging to the non-SC/ST/OBC group and the non-poor household in the age group of 60+ at higher risk of multi-morbidities. The Government hospitals overall enjoy higher acceptance though the reasons vary from their efficiency to lacuna in other healthcare providers. The study suggests incorporating the factors shaping the preferences to develop a suitable healthcare centre for the elderly and the expansion of government healthcare schemes. Successful ageing can get a boost by adequately addressing their healthcare needs.

Применение фазоманипулированных сигналов на базе последовательностей с исключительными корреляционными свойствами является одним из ключевых методов решения практических задач в подводной навигации, связи и томографии. В статье обсуждаются результаты исследований по распространению и приему широкополосных импульсных сигналов на основе псевдослучайных М-последовательностей. Исследованы особенности формирования импульсных откликов при приеме сигналов с различной частотной полосой и длительностью символов. Сделан практический вывод о необходимости комплексного применения различных по длительности символов навигационных сигналов при решении задач позиционирования автономных подводных аппаратов.

Utilization of phase-shift keyed signals based on sequences of outstanding correlation properties is one of the critical methods for solving the practical tasks in underwater navigation, communication, and tomography. The present work considers the results of experimental research on the propagation and reception of wideband impulse signals based on pseudorandom M-sequences. Throughout the experiments, the features of impulse response formation were investigated when receiving signals of different frequency bands and duration. The results of theoretical and experimental research suggest practical reasoning of the necessity of complex usage of navigational signals of different duration when solving the tasks of the autonomous underwater vehicle positioning.

Показано, что главные напряжения, в особенности тангенциальное напряжение, зависят от главных радиусов кривизны, а интенсивность напряжений зависит также и от утонения оболочек при сверхпластической формовке. Эти результаты достигнуты при сверхпластической формовке заготовок из алюминиевых сплавов AlMg5 и АМг6 (заготовка имела переменную толщину) и модельного сплава Sn-38 %Pb сверхпластичной и несверхпластичной модификации, определяемой по величине коэффициента скоростного упрочнения, равного 0,60 и 0,25 соответственно. Для оболочек с высотой, равной радиусу их основания, тангенциальные и меридиональные напряжения для сверхпластичного сплава Sn-38 %Pb приблизительно равны (погрешность – не более 18 %). Ухудшение сверхпластичных свойств сплавов вызывает превышение тангенциальных напряжений над меридиональными на 20–50 % в связи с существенным ростом меридиональных радиусов кривизны. В оболочках из заготовок переменной толщины соотношение главных напряжений, являющееся функцией относительного радиуса основания, имеет вид параболы с минимумом в местах сопряжения зон заготовки различной толщины. Погрешность отношения интенсивности напряжений в изучаемых оболочках к аналогичному показателю для формовки идеально сферической оболочки с неравномерной толщиной стенки равна 10 % для сверхпластичного сплава Sn-38 %Pb и возрастает до 20–30 % для других сплавов. Если предположить, что оболочка имеет контур идеальной сферы и равномерное утонение стенок вдоль контура, то указанная ранее погрешность отношения интенсивности напряжений возрастает до 50–130 %

Основной задачей при проектировании процессов правки является определение влияния режимов правки на энергосиловые параметры процесса и конечную кривизну листов. Наиболее точным методом моделирования процесса правки является метод конечных элементов. Основным недостатком этого метода является большое время реализации, что затрудняет решение задач оптимизационного плана. Основной целью работы было определение минимально достаточного количества конечных элементов для получения результатов с относительно минимальным размахом своих значений по мере протекания процесса. На основе реализации конечно-элементной модели процесса правки листов проанализировано влияние дискретности разбиения объема деформируемого материала на точность и время расчета с целью снижения затрат машинного времени при решении задач оптимизационного плана для определения режимов правки. Расчетная схема представляла деформируемый лист, 11 рабочих роликов с шагом 275 мм и диаметром 260 мм. Моделирование процесса правки было выполнено для листа толщиной 10 мм, шириной 2000 мм и длиной 3200 мм. Лист был представлен в виде пластически деформируемого тела, ролики – в виде абсолютно жестких тел. Задача была решена в двухмерной плоскости и в динамической постановке. По толщине из характера самого процесса правки листы были разбиты на пять элементов. При расчете силы правки на третьем ролике и ее коэффициента вариации было установлено, что при моделировании рациональным количеством является 6000 конечных элементов или 1875 элементов на погонный метр. При этом время реализации модели составило порядка 1,17 часа (Intel Core i5, 8Gb RAM) при вариации силы правки 0,01 и погрешности расчета меньше 1 % относительно более точного решения. Именно эта дискретизация является рациональной для постановки и решения задач по оптимизации технологических настроек многороликовой правильной машины
Ефективність балансування відцентрової сокодавки кульовим автобалансиром при здійсненні технологічного процесу
Authors: Goncharov V.
Published: October 2020

Показано, що використання автобалансира є ефективним при балансуванні відцентрової сокодавки при технологічному процесі. Він покращує вібраційні характеристики відцентрової сокодавки при кулях будь-якого розміру. Показано, що збільшення кількості куль приводить до покращення вібраційного стану відцентрової сокодавки при виконанні технологічного процесу. У випадку малих куль і при наполовину заповненій біговій доріжці вібрації (середньоквадратичне відхилення вібропришвидшення) відцентрової сокодавки зменшується майже на 53%. Пояснюється це наступним чином. В процесі роботи відцентрової сокодавки практично неперервно змінюється незрівноваженість сита і кулям в автобалансирі, відповідно, потрібно часто змінювати свої автобалансувальні положення (здійснюється велика кількість послідовних перехідних процесів). Процес балансування відцентрової сокодавки в цілому буде тим ефективнішим, чим меншою буде тривалість перебігу кожного перехідного процесу відносно інтервалу часу між змінами незрівноваженості. Тривалість перебігу перехідних процесів залежить, в основному, від відстані між сусідніми автобалансувальними положеннями куль та сил в’язкого опору відносному руху куль. Із збільшенням діаметру куль зменшується заповненість бігової доріжки, тому збільшення розміру куль призводить до збільшення відстані між сусідніми автобалансувальними положеннями куль і до збільшення тривалості перебігу перехідних процесів. При однаковій кількості мастила в автобалансирі кулі більшого діаметру є більш інертними і, відповідно, вони довше коливаються навколо своїх автобалансувальних положень. Деколи вони не встигають зайняти свої автобалансувальні положення до чергової зміни незрівноваженості. Отримані результати можна використовувати при конструюванні АБ для зрівноваження на ходу машин з швидкообертовими роторами, в яких незрівноваженість змінюється імпульсно і часто; для підвищення ефективності автобалансування ВСД в процесі експлуатації.

Определение личностных особенностей наркозависимых, детерминирующих динамику процесса ресоциализации
Authors: Mostova T.
Published: October 2020

Личность с наркотической зависимостью, которая находится в депрессивном состоянии проживает тяжелые эмоции и страдания. Актуальность нашего исследования заключается в изучении индивидуально-личностных особенностей, предрасполагающих к формированию длительной устойчивой ремиссии. Цель исследования — определить личностные особенности наркозависимых, на основании которых можно прогнозировать ход процесса ресоциализации и динамику течения состояния ремиссии. В качестве основного инструментария диагностики личностных особенностей наркозависимой личности выступал многофакторный личностный опросник MMPI в модификации 4.7 БМС (компьютерная версия). Для проведения дискриминантного анализа нами было отобрано 67 показателей, из 90-та личностных черт, диагностируемых опросником MMPI. Общую выборку данного исследования составило 309 человек. Из них основную экспериментальную группу, в дальнейшем группа I, составило 214 человека с диагнозом опийная наркомания I-II стадии, средний стаж употребления наркотических веществ составил 8,2 года, в возрасте от 19 до 36 лет, с ремиссией 12 суток. II группу – 38 респондентов с ремиссией от 1 до 3 лет, III группу – 12 респондентов с ремиссией больше 3 лет. Контрольную IV группу 45 человек, составили испытуемые, не имеющие в анамнезе диагноз «опийная наркомания». Полученный результат представлен как пространственная классификация испытуемых четырех обследуемых групп по результатам канонических дискриминантных функций. В результате, мы получили диагностический алгоритм на основе дискриминантного анализа у наркозависимых субъектов, позволяющий на основе рассмотрения девяти личностных характеристик, отнести субъект к группе наркозависимых и прогнозировать его движение в процессе ресоциализации. Психологический смысл выделенных переменных в характеристике наркотической зависимости состоит в том: чем выше адаптированность личности по таким показателям как Неискренность, Депрессивность, Шизоидность, Половая активность, Мнительность, Аморальность, Самоотчужденность, Социальная ответственность тем более она ориентирована на формирование устойчивой длительной ремиссии.

Methyl parathion (MP) is one of the most neurotoxic pesticides. An inexpensive and reliable one-step degradation method of MP was achieved through an aqueous suspension of copper(I) oxide nanoparticles (NPs). Three different NPs sizes (16, 29 and 45 nm), determined with X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM), were synthesized using a modified Benedict’s reagent. 1H nuclear magnetic resonance (NMR) results show that the hydrolytic degradation of MP leads to the formation of 4-nitrophenol (4-NPh) as the main product. While the P=S bond of MP becomes P=O, confirmed by 31P NMR. Although Cu2O is a widely known photocatalyst, the degradation of methyl parathion was associated to the surface basicity of Cu2O NPs. Indirect evidence for the basicity of Cu2O NPs was achieved through UV–vis absorption of 4-NPh. Likewise, it was shown that the surface basicity increases with decreasing nanoparticle size. The presence of CuCO3 on the surface of Cu2O, identified using X-ray photoelectron spectroscopy (XPS), passivates its surface and consequently diminishes the degradation of MP.

Authors: Phan Van Linh
Published: October 2020

Background: Extranodal NK/T-cell lymphoma, nasal type, is a rare subtype of non-Hodgkin lymphoma, origin from natural killer (NK) cells and T cells. This is a rare, fast-growing and poor prognosis disease. Currently there have been not many studies in Vietnam on this issue. We conduct this research with two objects: to describe characteristics of patients and evaluate premininary results of treatment extranodal NK/T cell lymphoma, nasal type, stage I to II at K hospital.

Methods: Retrospective study. From January 2017 to June 2020, we enrolled 26 patients with extranodal NK/T cell lymphoma, nasal type, stage I to II. Patients were treated concurrent chemoradiotherapy with cisplatin, followed by 3 cycles of VIPD adjuvant regimen.

Results: Patient characteristics: The average age was 43.2. Male/female ratio was 1.36. The most common symptoms were stuffy of nose 84.6%; runny nose 65.4%. Peripheral lymph nodes observed in 19.2%; 50% with B symptom. Staged I was dominated with 73.1%. Treatment results: Concurrent chemoradiotherapy phase: completed response was 26.9%, partial response 53.8% and progression disease 19.2%. At the end of treatment course, the overall response rate was 73% (including 61.5% completed response and 11.5% partial response), 26.9% cases with disease progression. Toxicity: Leukopenia was the most common toxicity (61.1%). Grade III and IV leukopenia were observed in 18.4%.

Authors: Nguyen Thi Thuy
Published: October 2020

Background: WHO 2008 classification of Non Hodgkin Lymphoma (NHL) has been introduced and got consensus internationally. However, studies on NHL according to WHO 2008 classification are limited in Vietnam. In terms of treatment, the R-CHOP regimen is still the most commonly used regimen for the treatment of moderate or high grade malignant lymphoma tumors. However, its effectiveness on each type has not been specifically studied. Purpose of this research is to evaluate of clinical and subclinical characteristics of NHL patients according to the 2008 WHO classification on lymphoid neoplasms and to evaluate preliminary effective of diffuse large B cell lymphoma (DLBCL) patients with R-CHOP regimen.

Materials and methods: A prospective descriptive study was conducted on 48 patients diagnosed with NHL undergoing treatment at the Hue University Hospital from July 2019 and Hue Central Hospital from April 2020 to present.

Results: The mean age was 52.4 years, male/female ratio = 1.3/1, the most common primary tumor site was lymph nodes with 54.3%. Stage IV was found in 37.5% of all cases. DLBCL was the most common type, accounted for 58.3%, whereas marginal zone lymphoma had the lowest incidence (2.1%). According to the International Prognostic Index (IPI), low risk, low-intermediate risk, high-intermediate risk, high risk group were 43.6%; 25.0%; 18.8%; 12.6% respectively. 34.8% patients responsed completely after 3 cycles and after 6 – 8 cycles, 58.8% patients achieved complete response. Grade III, IV neutropenia, grade I, II peripheral neuropathy and grade I, II thrompocytopenia were the most common side effect observed.

Conclusions: DLBCL is the most common Non Hodgkin Lymphoma. R-CHOP regimen has a good response after 6-8 cycles in DLBCL diseases and is well tolerated that the adverse events are mostly able to control effectively.
MIGRANT IMPACT ON THE DEVELOPMENT OF CREATIVE SOCIETY IN LITHUANIA: A CRITICAL OVERVIEW
Authors: Labanauskas Liutauras
Published: October 2020

Migration has become a significant issue in many countries and it has been highly debated topic in economic and social policy areas.
Only recently, the impact of migration on the culture, norms, values and development of creative society had begun to catch the attention of policymakers and
researchers. Migrant contributions to the society are seen not only as significant component to economies and their labour markets, but also as an important
factor in stimulating creativity and innovation. This paper analyses this inter-relatedness and presents empirically-based arguments in support of the position
that a migration can be regarded as the main prerequisite for the creation of a knowledge economy and as providing the potential for development of creative
and inclusive society.
Neutrino Counterparts of Fast Radio Bursts
Authors: Metzger Brian D. , Fang Ke , Margalit Ben
Published: October 2020

The discovery of a luminous radio burst, FRB 200428, with properties similar to those of fast radio bursts (FRBs), in coincidence with an X-ray flare from the Galactic magnetar SGR 1935+2154, supports magnetar models for cosmological FRBs. The burst’s X-ray to radio fluence ratio, as well as the X-ray spectral shape and peak energy, are consistent with FRB 200428 being the result of an ultra-relativistic shock (powered, e.g., by an ejected plasmoid) propagating into a magnetized baryon-rich external medium; the shock simultaneously generates X-ray/gamma-rays via thermal synchrotron emission from electrons heated behind the shock, and coherent radio emission via the synchrotron maser mechanism. Here, we point out that a unique consequence of this baryon-loaded shock scenario is the generation of a coincident burst of high-energy neutrinos, generated by photohadronic interaction of relativistic ions—heated or accelerated at the shock—with thermal synchrotron photons. We estimate the properties of these neutrino burst FRB counterparts and find that a fraction ∼10−8–10−5 of the flare energy (or ∼10−4–10−1 of the radio isotropic energy) is channeled into production of neutrinos with typical energies ∼TeV–PeV. We conclude by discussing prospects for detecting this signal with IceCube and future high-energy neutrino detectors.
FIRST J1419+3940 as the First Observed Radio Flare from a Neutron Star Merger

Published: October 2020

During their violent merger, two neutron stars can shed a few percent of their mass. As this ejecta expands, it collides with the surrounding interstellar gas, producing a slowly fading radio flare that lasts for years. Radio flares uniquely probe the neutron star merger populations as many events from past decades could still be detectable. Nonetheless, no radio flare observation has been reported to date. Here we show that the radio transient FIRST J1419+3940, first observed in 1993 and still detectable, could have originated from a neutron star merger. We carry out numerical simulations of neutron star merger ejecta to demonstrate that the observed radio light curve is well reproduced by a merger model with astrophysically expected parameters. We examine the observed radio data, as well as the host galaxy, to find clues that could differentiate the transient’s neutron star merger origin from the alternative explanation—the afterglow of an off-axis long gamma-ray burst. Near-future observations could find further evidence for the FIRST J1419+3940 radio transient’s origin. We show that existing radio surveys likely already recorded multiple radio flares, informing us of the origin and properties of neutron star mergers and their role in the nucleosynthesis of the heaviest elements in the universe.

Published: October 2020

In this article we consider certain linear time-varying control systems and investigate their stability using structured singular values ($\mu$-values). We use the low rank ordinary differential equations based methodology to compute the lower bounds for $\mu$-values. The inner-outer algorithm computes the local extremizer of an admissible perturbation and adjusts the desired perturbation level. Further, we present a comparison of our results via the well-known MATLAB routine mussv which is available in MATLAB control toolbox.
Teacher Experiences in Converting Classes to Distance Learning in the COVID-19 Pandemic
Authors: Marek Michael W. , Chew Chiou Sheng , Wu Wen-chi Vivian
Published: October 2020

The authors conducted a worldwide survey to explore the experiences of higher education faculty who converted classes to distance learning during the COVID-19 pandemic. Most respondents experienced much higher workloads and stress than in face-to-face classes. Previous experience with Online Distance Learning (ODL) predicted positive faculty response. Less than half used a school-provided LMS, instead using a wide range of other technologies. Respondents said they learned the need for adaptability and good planning, emphasizing doing what it takes to serve their students. There was high variability in most answers, indicating that the experiences of individual teachers ranged widely between positive and negative. The researchers provide recommendations based on the findings, including the need for better ODL instructional design training as part of long-term professional development for faculty and remembering the importance of all student higher education experiences, many of which are beyond the scope of the actual classes.

Published: October 2020

The aim of this research is to investigate the effect of the EDM process on the microstructure of CP-Titanium grade 2 and AISI 316 L in cardiovascular stent manufacturing. The microstructure was observed by an optical light microscope, and the microhardness test is conducted by microhardness vikers to validate the phase that is formed on the material. The pulse currents which were used in the manufacturing of stent by die sinking EDM were 1.5 A and 6.0 A. The experimental results show that the microstructure of CP-Titanium grade 2 is transformed after EDM in cardiovascular stent manufacturing, but it does not occur in the material AISI 316 L. The microstructure of CP titanium grade 2 is transformed from equiaxed α to be TiH for 1.5 A, and equiaxed α to be α’ martensite and TiH for the pulse current 6.0 A. The hardness of equiaxed α, α’ martensite, and TiH are 108 HVN, 113 HVN, and 254 HVN, respectively. The HAZ only occurs in the CP-Ti 2, and its depth for 1.5 A and 6.0 A are 45 μm and 73 μm, respectively.
Effect of Surface Treatment and Cutting Orientation to the Changes in Stents Surface Roughness

Published: October 2020

During the implantation process, an expandable balloon stent undergoes a change in mesh shape with a high strain rate. Permanent mesh shape changes to the stents indicate plastic deformation has occurred. On a micro-scale, plastic deformation has significant influence when interacting with the soft tissue of human blood vessels. This experimental study aims to investigate the effect of surface treatment and cutting orientation on the changes in surface roughness that definitely occurs when a stent deployed. To study the effect of surface treatment, two types of surface treatment were applied after surface polishing, i.e. etching and electropolishing. Surface polishing is carried out to enable microscopic observation. As for examining the effect of cutting orientation, the plate is cut in lateral and longitudinal orientation against the predicted-rolling direction of 316L sheet-type of stainless steel. An intermittent tensile test is conducted to obtain information about the changes in surface roughness. The surface observation is carried out three times on a similar surface of testpiece after reaching plastic deformation. The experimental study shows that the orientation of raw material has an insignificant effect on the changes in stent surface roughness. As for the surface treatments, electropolishing tended to decrease the tensile property of material.
