Published: December 2021

Introduction. The present review article is devoted to written Mongolian collections from repositories in different regions of Russia, which were formed thanks to the selfless work of brilliant Orientalists. At present, there is an urgent need in systematization, analysis, search for information, and distant access to archival records and written sources, which will give researchers more opportunities for distant work with sources. Accordingly, perspectives of using information technologies will fascilitate the coordination and wider cooperation, as well as greater openness in the academic environment, the urgency of which is quite obvious. It is the right moment, too, because, first of all, the data on written sources is still scattered in a variety of publications; secondly, 2018 saw the launch of a grandiose project ”World Heritage of Mongolians”, which is primarily designed to create a uniform inventory of historical-documentary heritage of Mongolian peoples. The project plans include the publication of twenty volumes to present collections of written monuments dispersed in various countries of the world: Russia, Japan, China, the USA, France, Denmark, Hungary, etc. Three volumes will be devoted to Mongolian sources from Russian repositories. The purpose of the present article is to give an overview of the repositories of the documentary heritage of the Mongolian peoples in different regions of Russia. Results. The largest collections of Mongolian written sources are stored in St Petersburg (Scientific Library of St Petersburg University, Institute of Oriental Manuscripts of the Russian Academy of Sciences, State Museum for the History of Religion, National Library of Russia), in Buryatia (Center for Oriental Manuscripts and Xylographs, Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the RAS; V. A. Obruchev Kyakhta Museum for Local Studies), in Tyva (Aldan-Maadyr National Museum of the Republic of Tyva, Scientific Archive of the Tyva Institute for Studies in the Humanities and Applied Socio-Economics), in the Republic of Tatarstan (National Archive of the Republic of Tatarstan), and in Kalmykia (Scientific Archive of the Kalmyk Scientific Center of the Russian Academy of Sciences, National Archive of the Republic of Kalmykia, N.N. Pal´mov Kalmyk Museum of Local Studies); these comprise representative collections, including rare and unique monuments of Mongolian written literature. Some of these collections have been studied to a degree, but there are still many to be introduced into scientific circulation. That is why it is of urgent importance to represent written Mongolian sources, their significant part kept in Russian repositories. Further work on identifying and describing the documentary heritage of the Mongolian peoples will contribute to our knowledge of the field that still needs to be investigated.
«Сказание о Гесере-богдо» в записи от Дорджиева Шарлда Дорджиевича, 1893 г. р.: общая характеристика, текст, комментарий
Authors:   Gorodovikov Kalmyk State University (11, Pushkin St., 358000 Elista, Russian Federation), Khabunovа Evdokia E.
Published: December 2021

Introduction. This paper introduces the authentic text of ”Gesr bogdyn tusk tuuji” (The Saga of Geser-bogdo) for the academic community. It was written down in Malye Derbety, Maloderbety raion, Kalmyk ASSR in 1982 by the present author; its performer was Sharlda Dordzhievich Dordzhiev (1893–1984), Baga khurul shabiner, uimguilmyd. The original text is supplemented by Russian translation made by the author of the publication and a short biography of the performer. Also, the article includes a brief description of the sample, focusing on the specifics of recording and of keeping the field notes. The article aims at introducing new material, such as the authentic text ”The Saga of Geser-bogdo”, its Russian translation, and the performer’s biographical data. Data and methods. The research is based on the manuscript from the author’s private archive; the Kalmyk text of eleven pages is written down on paper (A4, yellow paper). There are also additional materials, such as the interviews with Dordzhiev’s relatives and villagers. Results. ”The Saga of Geser-bogdo” is devoted to an interesting story of Geser-bogdo’s mission, i. e. the protagonist’s efforts to free the Earth (Middle World) from cold, as well as demons personified as Andzhlula and his wife. The narrative is based on two microstories: i) an unsuccessful attempt to getrid of cold on the Earth with the help of Khurmusta Tengri and ii) the victory over Andzhlula and his wife with the help of Sandzhi, the protagonist’s brother from heavens. The analysis shows that, in terms of its structure and content, ”The Saga of Geser-bogdo” includes a number of important segments, which are parallel to other Geser’s epic narratives. The manuscript is of relevance for studies of the Kalmyk oral tradition of Geser sagas. Conclusions. ”The Saga of Geser-bogdo”, performed by Dordzhiev in 1982, indicates that oral retellings of Geser sagas were widely circulated in Kalmykia. Also, the data pertaining to the storyteller’s life and art shows the popularity of the epic narratives in the Kalmyk milieu at the time the recording was made (late 20th c.). The epic sample maybe of interest to folklorists and epic scholars for their comparative and textological studies, as well as for the studies of storytelling tradition and of the linguistic aspect of popular oral art.

PV Based Automatic Irrigation System
Authors: Naik M. Sreenivasulu
Published: December 2021

Abstract: In Because of the lack of rains and scarcity of land reservoir water, proper irrigation methods are critical in the field of agriculture. The continuous extraction of water from the earth is lowering the water level, causing a lot of land to slowly come into the unirrigated zones. Another important reason for this is because of unplanned water use, which wastes a significant amount of water. This automatic plant irrigation system is used for this purpose. Solar energy is used to power the system via photovoltaic cells. As a result, there is no need to rely on erratic commercial power. In this digital age, we demand that everything around us be automated, reducing human effort. Electronic circuits are becoming more prevalent, making life easier and simpler in today's world. Energy and water scarcity are two major issues that everyone is dealing with these days. As a result, energy and water conservation are required. The goal is to create a solar-powered prototype that will automatically irrigate the field. Consider how convenient it will be to be able to focus on your next task while your field is being irrigated automatically and at a low cost. No worries about underirrigation or over-irrigation, water waste or expensive electricity, or your busy schedule.

Kebangkitan Politik Identitas dalam Proses Demokratisasi di Indonesia Pasca Orde Baru
Authors: Mahpudin
Published: December 2021

Tulisan ini berupaya menjelaskan bagaimana kebangkitan politik identitas di Indonesia pasca Orde Baru. Guna menjawab pertanyaan tersebut, tulisan ini menggunakan teori tentang politik identitas dan metode penelitian kualitatif–deskriptif, dengan pengumpulan data dilakukan melalui kajian literatur. Hasil kajian menyimpulkan bahwa Kebangkitan politik identitas di Indonesia pasca Soeharto menyebabkan pejalanan demokrasi di Indonesia selama dua dekade tidak berjalan maju ke arah demokrasi substansial. Demokrasi Indonesia pada akhirnya masih terjebak pada demokrasi prosedural yang hanya berkelindan soal urusan pemilu dan proses pergantian elit. Namun dalam praktik kehidupan warga negara masih belum menunjukkan kehidupan yang demokratis. Berbagai kasus kekerasan dan intoleransi serta menguatnya sentimen identitas atas dasar etinisitas dan agama telah menimbulkan praktik diskriminasi dan pengeksklusian terhadap kelompok identitas lain yang berbeda. Kondisi ini sering kali dimanfaatkan oleh elit politik yang memainkan peran penting dalam mempertajam sentimen identitas dan agama untuk mendapatkan kekuasaan, terutama memasuki masa pemilu.

Authors: Netto Livian Lino , Ebersol Isadora , Clasen Júlia Da Rocha
Published: December 2021

Neste trabalho propomos refletir a Maré Verde como expressão de um marcante momento na história do movimento feminista internacional, que aconteceu na Argentina, no dia 30 de dezembro de 2020. Neste dia, com 38 votos a favor, 29 contra e uma abstenção, o senado argentino aprovou a lei que permite que a interrupção voluntária da gravidez seja realizada de maneira legal, segura e gratuita para mulheres até a 14ª semana de gestação. Ao propor uma reflexão a partir da análise de conjuntura produzida sobre esse momento, não nos referimos somente a vitória institucional que isso representa, enquanto direito social historicamente reivindicado, mas sobre a sua construção enquanto parte de um conjunto de pautas políticas de uma resistência que não se encerra naquele momento, mas sua vitória potencializa um conflito político historicamente travado pelas mulheres do Sul Global. Neste trabalho concluímos que a ação política travada pelas mulheres argentinas reflete na articulação do movimento feminista na América Latina e no denominado Sul Global, como expressão de uma reivindicação de caráter histórico conflitivo da sua resistência.

Scattering of anti-plane waves by scalene trapezoidal boundary with embedded cavity in anisotropic material based on mapping space
Authors: Sun Yingchao , Yang Zailin , Li Yuliang , Lin Haibin
Published: December 2021

Both surface motion and hole stress concentration have always been
concerned in anisotropic medium. In this paper, a theoretical approach
is used to study the scattering problem of circular holes under a
scalene trapezoid on the surface. The mapping function that anisotropic
medium to homogeneous medium is established, and the relationship
between the free boundary of anisotropic medium and the mapping of
homogeneous medium boundary is proved. In the space of homogeneous
medium mapping, the wave displacement function is obtained by solving
the equation of motion that meets the zero-stress boundary conditions by
separating the variable method and the symmetric method. Based on the
complex function, multi-polar coordinate method and region-matching
technique, algebraic equations are established at auxiliary boundary and
free boundary conditions in complex domain. Then according to sample
statistics, least square method is used instead of the Fourier expansion
method to solve the undetermined coefficient of the algebraic equations
by discrete boundary. Numerical results shows that the continuity of the
auxiliary boundary and the accuracy of the zero-stress boundary are
nice, and the displacement of the free surface and the stress of the
circular hole are related to the parameters of material medium, the
position of the circular hole, the direction of the incident wave and
the frequency content of the excitation. Finally the process of the wave
propagation and scattering around trapezoid and shallow circle are shown
in time domain through the inverse fourier transform.

Objective No study ever investigated the long-term risk of stroke in
women with pre-eclampsia/eclampsia. The purpose of this study is to
explore long-term stroke risks, differentiating subtypes and their time
trends. Design Nationwide population-based cohort study Methods Between
2000 and 2017, 1,384,427 pregnant women were registered in the National
Health Insurance Research Database in Taiwan. After excluding women with
previous stroke history and exact matching with all confounders, 6,053
women with pre-eclampsia/eclampsia and 24,212 controls were recruited.
Main Outcome Measures Hemorrhagic and ischemic strokes after child-birth
Results Over the 17-year follow-up, the adjusted hazard ratio (aHR) for
stroke in women with a history of pre-eclampsia/eclampsia was 2.05 (95%
confidence interval, CI = 1.67-2.52, p<0.001). The 17 years
overall risks of both ischemic and hemorrhagic stroke were 1.98 and
3.45, respectively (p<0.001). The stroke subtypes, hemorrhagic
and ischemic, had different time trend risks, and hemorrhagic stroke
risks kept higher than that of ischemic stroke. The ischemic stroke risk
peaked during 1-3 years after childbirth (aHR=3.09). The hemorrhagic
stroke risk peaked during 3-5 years (aHR=7.49). Conclusions Stroke risk
persisted even after decades, for both ischemic and hemorrhagic
subtypes. Women with pre-eclampsia/eclampsia history should be aware of
the long-term risk of stroke. Tweetable abstract Both ischemic and
hemorrhagic stroke risks persisted high even after decades, while their
time trend risks were different. Keywords: pre-eclampsia/eclampsia;
ischemic stroke; hemorrhagic stroke
Kappa opioids inhibit the GABA/glycine terminals of rostral ventromedial medulla projections in the superficial dorsal horn of the spinal cord
Authors: Otsu Yo , Aubrey Karin
Published: December 2021

Background and Purpose: Descending projections from neurons in the
rostral ventromedial medulla (RVM) make synapses within the superficial
dorsal horn of the spinal cord that are involved in acute nociception
and the development of chronic pain and itch. In addition, this
projection plays an important role in mediating the analgesic effects of
opioids. However, our knowledge about the spinal synaptic targets of RVM
projections and their modulation by opioids is unknown. Experimental
Approach: We used ex vivo optogenetic stimulation of RVM descending
fibres and whole-cell patch-clamp recordings from superficial dorsal
horn (SDH) neurons to identify the target neurons and to investigate
their descending synaptic inputs. Key Results: We demonstrate that SDH
neurons are targeted by descending GABA/glycine inhibitory inputs from
the RVM, although glycinergic inputs predominate. These SDH neurons had
diverse morphological and electrical properties. This inhibitory synapse
was presynaptically suppressed by the kappa opioid receptor agonist
U69593. By contrast, the mu-opioid receptor agonist DAMGO inhibited only
a subset of RVM-SDH synapses, acting both pre- and postsynaptically,
while the delta-opioid receptor agonist deltorphin II had little effect.
Conclusion and Implications: Developing reliable and effective
alternatives to opioid analgesics requires a detailed, mechanistic
understanding of how opioids interact with nociceptive circuits. This
study selectively and systematically characterises the synaptic
connections between RVM projection neurons and their SDH targets to
advance our knowledge of how this descending projection is organised and
modulated. In addition, it improves our understanding of how opioids
alter spinal pathways involved in the sensations of pain and itch.
Developing a Risk Management System for Participating Government Agencies of India
Authors: Banerjee Pritam , Sanganeria Atul
Published: December 2021

Trade facilitation is a critical building block of developing globally integrated value chains. In India, current trade facilitation systems including risk assessment criteria require improvements involving regulatory mandates for food and drugs, animal and plant quarantine, wildlife protection, and textile products. Using illustrative examples, this working paper presents specific system development needs for six major participating government agencies on trade facilitation in India. It provides a model for developing a comprehensive system of risk management. It also discusses the need for institutional cooperation between customs authorities and participating government agencies for a comprehensive single window trade facilitation solution.
Controlled electron leakage in electron blocking layer free InGaN/GaN nanowire light-emitting diodes
Authors: Velpula Ravi , Jain Barsha , Lenka Trupti , Nguyen Hieu
Published: December 2021

In this study, we have proposed and investigated the effect of coupled
quantum wells to reduce electron overflow in InGaN/GaN nanowire white color
light-emitting diodes. The coupled quantum well before the active region
could decrease the thermal velocity, which leads to a reduced electron mean
free path. This improves the electron confinement in the active region and
mitigates electron overflow in the devices. In addition, coupled quantum
well after the active region utilizes the leaked electrons from the active
region and contributes to the white light emission. Therefore, the output
power and external quantum efficiency of the proposed nanowire LEDs are
improved. Moreover, the efficiency droop was negligible up to 900 mA
injection current.
Culture of the “new normal” - terminological meaning(s) and use(s)
Authors: Trifunovic Vesna , Djordjevic Ivan
Published: December 2021

This paper discusses the different meanings and uses of the term ?new normal?
by taking into account the historical perspective and contemporary use of
the term which has reemerged as a consequence of the outbreak of the
COVID-19 pandemic. The authors focus on the processes that through this term
define everyday life in pandemic circumstances, determined by the need for
adjusting and for (re)negotiating and (re)positioning of diverse actors in
positions of power. The unpredictable outcome of the still-ongoing pandemic
additionally gives importance to the study of these new circumstances within
social sciences and humanities, to which this special issue is dedicated to.
COVID-19 as a Badiouian event? A global insight into theoretical interrogation of Zizek’s pandemics
Authors: Lero Nikola
Published: December 2021

The rapidly burgeoning literature surrounding COVID-19 pandemic
fetishistically and prematurely tried to catch the academic momentum, taking
almost an a priori, non-debatable, starting point of the conceptualization
of the pandemic as the ?new normal?. In Pandemic: COVID-19 Shakes the World
and Pandemic! 2: Chronicles of a Time Lost, Slavoj Zizek frames the pandemic
as multiple global crises, arguing it will aggressively and drastically
rupture the global societal norms and dynamics creating a new order.
However, did it? This essay debates this question through the theoretical
lenses of Badiou?s Event. It starts by laying down the fundamental
theoretical principles and mapping the necessary criteria needed to be
fulfilled in order for a happening to be named an Event. Further, it
navigates through ideas and arguments presented in Zizek?s publications
localizing the pandemic?s global characteristics. Finally, it theoretically
deconstructs them providing us with the fundamental answer to the question
what COVID-19 pandemic is: a Badiouian event that has/is/will construct the
global ?new normal?, multiple consequential crises, or just a temporary
situation that reaffirms the existing societal normatives worldwide.
Noises in communication: “double bind” during the epidemic of COVID-19 in Serbia
Authors: Stajic Mladen , Zikic Bojan , Pisev Marko
Published: December 2021

In this paper, through the application of the concept of double bind,
formulated by the British anthropologist Gregory Bateson and his associates,
the communicative contradiction of messages and instructions related to
behavior in circumstances of epidemiological danger, announced by the
government officials, doctors and the Crisis Staff during the corona virus
epidemic in Serbia will be considered, as well as the consequences of such
communication dissonance on the public perception of preventive and
restrictive measures. The concept of double bind, which implies
communication during which an individual or group from the position of
authority continuously receives two or more conflicting messages that are
mutually exclusive, without the possibility of feedback and resolving
contradictions, is applicable to any type of cultural communication where it
is important, although difficult, to correctly distinguish the obtained
information. During the COVID-19 epidemic in Serbia, public messages
concerning the degree of danger posed by the virus, contagion and mortality,
vulnerable groups, the possibility of acquiring collective immunity,
effective prevention measures, etc., were often accompanied by contradictory
statements from policy makers or their actions, behavior and non-verbal
communication that were contrary to what was verbally communicated and
recommended. Since the communication was mostly oneway during the epidemic,
because information was announced from the position of authority, through
the media and at press conferences that were suspended for a certain period,
without the possibility of clarifying the dilemmas, the collective
dissatisfaction of recipients caused by misunderstandings and contradictions
often manifested itself through humor, satire, refusal of obedience,
protests, etc. This paper will consider the way in which double bind can
represent a form of control and a shift of responsibility not only at the
individual or family level, but also at the level of the society as a whole.
The epidemic as a ‘regulator’ of interpersonal relationships: The impact of ‘combined’ schooling on the relationship among primary school students
Authors: Andjelkovic Biljana , Nedeljkovic Sasa
Published: December 2021

The paper presents a case study whose focus is on examining the relationship
among students of one fifth grade class during the period of combined
schooling in the school year 2020/2021. This schooling model was introduced
in order to enable appropriate physical distance among students in the
classroom. Also, this was one of the important preventiv measures of the
COVID-19 epidemic. Our intention is to check whether and to what extent the
application of this schooling model, which included the division of classes
into two groups, reflected on the mutual relations of students. We paid the
most attention to friend?s relations. This paper represents an
anthropological contribution to the issue of interpersonal relations among
children in condition when many relations in society have changed due to the
?new normality?.
Can the China's fast telescope detect extraterrestrial von-Neumann probes?

In the present paper we consider the Type-2.x and Type-3.x extraterrestrial
von- Neumann probes and study the problem of their detectability by the
world's largest single-dish radio telescope: the Five-hundred-meter Aperture
Spherical Radio Telescope (FAST). For this purpose we estimate the radio
spectral parameters and analyse the obtained results in the context of
technical characteristics of FAST. As a result, it is shown that FAST can
detect both the galactic and extragalactic self-replicating probes with high
precision.
Towards better correlation between optical and commercial spark ignition engines through quasi-dimensional modeling of cycle-to-cycle variability
Authors: Irimescu Adrian , Merola Simona , Vaglieco Bianca
Published: December 2021

Internal combustion engines are still the main choice when considering propulsion technology in the transport sector. Spark ignition units offer the advantage of good efficiency with simpler after-treatment systems. Lean operation is a promising strategy that would further improve efficiency, but requires mitigation of cycle-to-cycle variability. Within this context, and given the increasing trend of using simulation based evaluations during engine development, the current work investigated combustion in an optical spark ignition engine through measurements and quasi-dimensional simulation. The possibility of visualizing in-cylinder processes provides unique insight, but also introduces complications with respect to commercial engines. For this reason, quasi-dimensional simulation was applied so as to better understand the factors that induce cycle-to-cycle variability. For the specific case of the investigated engine, cycle-to-cycle measured exhaust air-fuel ratio was found to be directly correlated to variations of engine output. Several routes of incorporating these effects into simulations were evaluated. Introducing a random component in the period of laminar-turbulent flame transition was found to ensure good grounds for simulating peak pressure variability. Indicated mean effective pressure on the other hand was found to depend less on the initial stages of combustion and was strongly correlated to aforementioned variability of exhaust air-fuel ratio.
A detailed analysis of flow and heat transfer characteristics under a turbulent intermittent jet impingement on a concave surface
Authors: Hajimohammadi Ali , Zargarabadi Mehran , Mohammadpour Javad
Published: December 2021

A computational study is carried out of the 3-D flow field and heat transfer under a turbulent intermittent circular jet impingement on a concave surface. The control-volume procedure with the SIMPLE algorithm is employed to solve the unsteady RANS (use full form) equations. The RNG k-? model is implemented to simulate turbulence due to its success in predicting similar flows. The numerical results are validated by comparing them with the experimental data. The effects of jet Reynolds number and oscillation frequency on the flow and heat transfer are evaluated. The profiles of instantaneous and time-averaged Nusselt numbers exhibit different trends in axial, x-directions and circumferential, s-directions. It is found that increasing frequency from 50 to 200 Hz results in considerable time-averaged Nusselt number enhancement in both axial and curvature directions. The intermittent jet at a frequency of 200 Hz enhances the total average Nusselt number by 51.4%, 40%, and 33.7% compared to the steady jet values at jet Reynolds numbers of 10000, 23000, and 40000, respectively. In addition, a correlation for the average Nusselt number is proposed depending on the Reynolds number and the Strouhal number.

Authors: Zhang Ruihao , Zhang Hao , Qing Shan , Zhang Xiaohui , Luo Zhumei , Zhu Xiangdong
Published: December 2021

Nanofluids due to their good thermal conductivity and stability, have been
proposed as a way to surpass the performance of currently available heat
transfer fluids in the near future. In this work?we focuses on the
preparation of nanofluids with excellent stability and thermal conductivity,
which a new type of stable BiOIO3 (one type of infrared nonlinear optical
crystal) nanofluids is successfully prepared by using the two-step method.
After the initial physical characterization of BiOIO3 particles, five
different dispersants are used to disperse the BiOIO3 nanoparticles, and the
best performing nanofluids with a zeta potential value of 144.45 and an
average particle size of 22.90nm could be prepared with PVP dispersant.
Furthermore, the addition of PVP dispersant in UV-Visible experiments smooth
the light absorption curve of the nanofluids, reach a peak of 1.1 at around
350 nm. In the most important thermal conductivity test, the value of
thermal conductivity of BiOIO3 nanofluid becomes larger with increasing
concentration at 50?C, reaching a maximum value of 1.52 at 0.134vol%, which
increases by 0.72 over the same volume concentration of TiO2, indicating the
importance of the laminar structure. In view of the excellent properties,
new laminar structured nanofluids with light-absorbing properties are
expected to receive more attention and exploration in the future
Thermal management and phase change heat transfer characteristics of LiFePO4 batteries by cooling phase change materials
Authors: Wang Yaoting , Meng Tong , Chu Wenxiao
Published: December 2021

The cycle life and thermal safety of lithium-iron-phosphate (LiFePO4) batteries are important factors restricting the popularization of new energy vehicles. The study aims to prevent battery overheating, prolong the cycle life of power batteries and improve their thermal safety by discussing the heat production of LiFePO4 batteries to solve the problem of temperature rise in the natural-convection environment and cut the energy consumption in the liquid cooling system. A numerical simulation and experiment are employed to study the heat production characteristics of LiFePO4 batteries and the heat transfer characteristics of the system, with its PCM and coupling PCM of paraffin and expanded graphite), channel liquid, and micro-channel PCM coupling cooled to control the temperature of the batteries. The results show that the temperature goes higher with the discharge rate during discharge. Since it has large internal component values, LiFePO4 produces more heat at the beginning and end of discharge. When the battery pack is discharged at 1C and 2C rates, the mass-flow rates are 1.8 ? 10?3 kg/s and 3.6 ? 10?3 kg/s, the temperature can be controlled at most 40?C, and the temperature difference less than 3?C, respectively. Paraffin is composed of expanded graphite, and the thermal conductivity of the composite heat storage PCM (phase change heat storage materials) is 24 times of that of pure paraffin. Therefore, cooling the active liquid and coupled PCM can improve the cooling efficiency and has a good effect on solving the problem of temperature rise and energy consumption reduction. The research provides a reference for the thermal energy management of LiFePO4 batteries, providing a method of cooling PCM of LiFePO4 batteries.

Most
genome-wide association studies (GWAS) of complex traits are performed using
models with additive allelic effects. Hundreds of loci associated with type 2
diabetes have been identified using this approach. Additive models, however, can
miss loci with recessive effects, thereby leaving potentially important genes
undiscovered. We conducted the largest GWAS meta-analysis using a recessive
model for type 2 diabetes. Our discovery sample included 33,139 cases and
279,507 controls from seven European-ancestry cohorts including the UK Biobank.
We identified 51 loci associated with type 2 diabetes, including five variants
undetected by prior additive analyses. Two of the five had minor allele
frequency less than 5% and were each associated with more than doubled risk in
homozygous carriers. Using two additional cohorts, FinnGen and a Danish cohort,
we replicated three of the variants, including one of the low-frequency
variants, rs115018790, which had an odds ratio in homozygous carriers of 2.56
(95% CI 2.05-3.19, P=1´10-16) and a
stronger effect in men than in women (interaction P=7´10-7). The signal was associated with
multiple diabetes-related traits, with homozygous carriers showing a 10%
decrease in LDL and a 20% increase in triglycerides, and colocalization
analysis linked this signal to reduced expression of the nearby PELO
gene. These results demonstrate that recessive models, when compared to GWAS
using the additive approach, can identify novel loci, including large-effect
variants with pathophysiological consequences relevant to type 2 diabetes.

Authors: Rakhmadi Aris , Ariyanto Ragil
Published: December 2021

Cerebral palsy (CP) is a mobility disorder, muscle tone or posture disruption caused by brain damage that appears during brain growth, and often occurs before birth. CP has an impact on the daily activities of the suffered patient. Gross Motor Function Measure (GMFM) is a type of clinical measurement to evaluate development progress in the motoric function of CP patients. The purpose of this research is to design software to monitor and evaluate motoric parameters of CP patients. The software implements the GMFM method. The development mechanism went through the process of Software Requirements Specification (SRS). The result shows that the software helps monitor and evaluate CP patients. Software application in the field assists in evaluating the initial examination of T-1 until the final examination of T-6. Records show the enhancement dimensions of lying and rolling by 13.3%, sitting 14.8%, crawling and kneeling by 15.7%, standing by 16.5%, and walking-running-jumping 17.4%. We conclude that the application supports recording and analyzing motoric cerebral palsy data.

Published: December 2021

Diabetes Mellitus is one of the preeminent causes of death to date. Effective procedures are necessary to prevent diabetes and avoid complications that may cause early death. A common approach is to control patient blood glucose, which necessitates a periodic measurement of blood glucose concentration. This study developed a blood glucose prediction system using a convolutional long short-term memory (Conv-LSTM) algorithm. Conv-LSTM is a variation of LSTM algorithms that are suitable for use in time series problems. Conv-LSTM overcomes the lack in the LSTM algorithm because the latter algorithm cannot access the content of previous memory cells when its output gate has closed. We tested the algorithm and varied the experiment to check the effect of the cross-validation ratio between 70:30 and 80:20. The study indicates that the cross-validation using a ratio of 70:30 data split is more stable compared to one with 80:20 data split. The best result shows a measure of 21.44 in RMSE and 8.73 in MAE. With the application of conv-LSTM using correct parameters and selected data split, our experiment attains accuracy comparable to the regular LSTM.

Gastrointestinal stromal tumors (GIST) account for 1% to 3% of gastrointestinal tract tumors and are the most common of the mesenchymal tumors. Carcinogenesis of GIST arises in the interstitial cells of Cajal (ICC) and in the myenteric plexus of the gastrointestinal tract due to a mutation of the kinase receptor (KIT, also known as CD117) and the platelet-derived growth factor A (PDGFA) gene leading to activation of the tyrosine kinase receptor. The exact incidence and prevalence of GIST is not known. Symptoms of GIST are non-specific; they present with GI bleeding due to ulceration (50%), abdominal pain (20% to 50%), dysphagia (esophageal GIST) and GI obstruction (10% to 30%) (7,10). Signs include abdominal mass and fullness. A computerized tomographic (CT) scan is the preferred imaging to evaluate GIST. Diagnosis is confirmed by immunohistochemical (IHC) staining a of biopsy sample for medical treatment tyrosine kinase inhibitors (TKI). Surgical resection with negative microscopic margins is the gold standard treatment of GIST. TKI are required for tumor reduction to increase chances of respectability (neoadjuvant therapy) or to prevent recurrence and reduce the progression of advanced, resectable GIST.

Purpose: Science mapping is commonly known as Scientometrics; is used in combination with data visualization to analyze a considerable form of bibliographic resources to study and map the scientific field and thereby serving investigators to concentrate on under investigated areas of research. This scientometric study was aimed: 1) to evaluate the level of investigation in the field of periodontitis and osteoporosis, and 2) to recognize the journals, and countries in this field.

Methods: The top hundred articles with most citations were selected by electronic searches in the MEDLINE database, and the citations were cross checked by Google Scholar database. The total number of publications per year along with their yearly growth was calculated. The following data regarding the journal, country of origin, and level of evidence were analysed.

Results: 467 authors within 77 clusters contributed to these 100 articles. The annual rate of growth of publications in the period from 2011 to 2020 was 6.27%. The year range of these publications started from 1992 till 2019, the second decade of the new millennium showed the highest number of articles (39 out of 100 articles).

Conclusion: Though the number of articles published on the present topic has risen in the last two decades, the proportion of studies with LOE1 is as low as 5%. Therefore, recommendations are made to the researchers to lay emphasis on producing more studies with LOE1 in future.

Hybrid Learning Using Canvas LMS
Authors: Al-Ataby Ali
Published: December 2021

Hybrid learning refers to the learning style where online components are used to replace some face-to-face elements of the course. In the current era, where COVID-19 pandemic has highly impacted higher education, online and remote forms of learning have become critical success factors to deliver engaging and rich teaching and learning experience to the students. With the partial return of face-to-face interaction with the students this year after easing restrictions, universities have no choice but to offer hybrid learning experience. In the journey towards this type of learning, a transition in both pedagogy and vehicle (tools) is inevitable. Hybrid learning pedagogy has been in literature for many years now and many institutions worldwide have enough experience to run courses and programs as a hybrid model. For the vehicle, a number of tools are necessary to facilitate delivery, but the most important tool is obviously the learning management system (LMS). Canvas LMS is now considered one of the most commonly used electronic learning systems, offering a large number of features and options to make teaching and learning easier and effective for both teachers and students. In this paper, two hybrid learning models are proposed. An example of implementing one of the two models using Canvas LMS and other supporting tools is provided. Anecdotal student feedback has shown that the students were highly engaged and their experience has been improved as a result of the hybrid delivery format.
Numerical Investigation of the Performance of Linear Interpolation Schemes Coupled Finite Volume Method in the Analysis of Confined Convection-Diffusion Turbulent Flow Field
Authors: Gatwiri Jane , Karanja Stephen , Theuri David
Published: December 2021

Numerical solutions are never exact due to errors emanating from the scheme used in discretizing the governing equations and the flow domain. For convection-diffusion flow, the magnitude of these errors varies depending on the scheme used to interpolate the nodal values of the flow quantities to the interfaces. An interpolation scheme that minimizes these errors would give results that are consistent to experimental results. This paper documents the performance of three linear interpolation schemes; upwind differencing, central differencing scheme and the hybrid scheme in obtaining temperature profiles for a convection-diffusion turbulent flow field. To eliminate the enormous scales inherent in turbulent flow, the field variables present in the governing equations are decomposed into a mean and a fluctuating component and averaged. The closure problem was solved using the  turbulence model. The resulting equations are discretized using the robust finite volume discretization technique. The discretized equations are solved using a segregated pressure-based algorithm. The results revealed that the central difference interpolation scheme generate temperature profiles that were consistent with experimental results of Ampofo and Karayiannis, (2003).
