Obesity and cancer: the gammadelta T cell link
Authors: Bank Ilan
Published: May 2022

Obesity has become a worldwide scourge, affecting more than 10% of adults worldwide. While widely recognized to be associated with increased incidence of medical conditions such as diabetes mellitus and atherosclerosis, obesity also accounts for 9% of the cancer burden in some populations. This is due in part to perturbation of protective immune mechanisms involving natural killer cells, macrophages, and neutrophils. Recent studies indicate that γδ T cells play a prominent protective role against cancer, but in some circumstances are detrimental and pro tumorogenic. In this review, the current scientific literature was explored to determine whether and how obesity affects the anti- and pro-tumoral functions of γδ T cells. Considerable perturbations of γδ T cells by obesity were revealed, suggesting that the “obesity-γδ T cell axis” may profoundly impact the increased incidence of cancer in obese individuals and is worthy of further study.

Authors: Swami Yashu
Published: May 2022

Adiabatic logic guarantees vast diminishments of power utilization since it doesn't disperse power. This paper audits ongoing advancement in adiabatic circuits. First, the fully adiabatic circuit designing technology called as pass-transistor adiabatic logic (PTAL) is discussed. Next, the operation of the dual rail logic and the power clock supply with the logic operation of the PTAL technology is discussed. Further, many basic logic circuits using the PTAL technology are designed, compiled and simulated. Finally, the performance results, power dissipation, speed, efficiency and load analysis of the circuits are compared with the conventional and existing CMOS technology under same simulation conditions using standard 45nm technology with VDD = 1V and proves that even at high frequencies above 2GHz, it is able to outperform the dominating conventional CMOS logic designing in the field of power dissipation. The simulation results are provided to support our claim. We used 45nm technology for all our simulations.

Published: May 2022

Uranium and Thorium are natural elements known for their radioactive properties that can be used as a source of nuclear power. Both Uranium and Thorium are new energy sources, and are classified as alternative nuclear fuels, they are known as green nuclear. Uranium is not a rare metal, it is estimated that there are 5.7 million tons of uranium reserves in the world in 2015 in the Red Book of The Organization for Economic Co-operation and Development-Nuclear Energy Agency (OECD-NEA). As for Thorium, which is a heavy metal content in the earth's crust, it has reserves of 6.3 million tons in the world. Compared to Uranium, Thorium has a more even distribution and one of them is found in Indonesia. The National Nuclear Energy Agency (BATAN) stated that Indonesia has 79,830 tons of uranium reserves and 136,966 tons of Thorium, which are scattered in the Bangka Belitung Islands, Kalimantan Island and Sulawesi Island. The purpose of this paper is to examine the potential of Uranium and Thorium in Indonesia, including the amount of reserves, their distribution and future prospects in order to support the nation's energy security, because in Indonesia, nuclear is used for peaceful purposes, namely as a power plant.
RELIGIOUS SECTARIANISM AND ITS IMPACT ON POLITICAL STABILITY IN LEBANON

Lebanon is the best study of a sectarian society par excellence, having been the focus of attention of regional and international powers throughout history, an international war theatre with recurrent and various wars. Sectarianism is not a sign of weakness in the Lebanese political system because of the diversity of sects. This diversity existed prior to the establishment of the state. It has to do with sectarianism's psychological impact on the religious community, which is reflected in how individuals approach other groups or sects. And speculation about the goals and reasons of other groups' social and political activities, as well as the consequent conduct, can only be founded on aggression and rejection of the other, culminating in long-term instability for the latter.

Published: May 2022

Batteries are an efficient medium for storing energy. Its small size, reliability and light weight make batteries a widely used choice as a power source for small electronic equipment. Currently existing nuclear battery technology can only produce very little electrical power. Even so, nuclear battery technology is predicted to develop rapidly in the next few years. This article discusses the characteristics of radioisotopes which are suitable for making nuclear batteries. The characteristics considered are the type of radiation, other types of radiation emitted by the radiation source, the production method of radioisotope, the half-life of the radioisotope, and the decay energy of the radiation.

La enfermedad venosa crónica (EVC) se trata de una amplia variedad de anomalías del sistema venoso de gran prevalencia en nuestra sociedad. Frecuentemente, se manifiesta en las extremidades inferiores en forma de vena varicosa (VV), cursando como una situación de hipertensión venosa ambulatoria que se agrava conforme progresa la enfermedad. Cada vez más estudios evidencian la importancia de los cambios moleculares y de la matriz extracelular en la fisiopatogenia de la EVC. EGFL-7 (Epidermal growth factor-like domain-containing protein 7) es un componente de gran importancia en el desarrollo y patología del sistema vascular, aunque su papel en la EVC todavía no ha sido esclarecido. Así, el objetivo del presente trabajo es analizar la expresión génica y proteica de EGFL7 en la pared venosa de pacientes con EVC (n=35) y sanos (n=27), mediante la realización de RT-qPCR e immunohistoquímica, respectivamente. Nuestros resultados muestran como existe una disminución en la expresión de EGFL-7 en pacientes con EVC en comparación con las venas de individuos sanos. En su conjunto, nuestro trabajo apoya el papel de EGFL7 en la pérdida de la homeostasis vascular asociada a la EVC. Futuros estudios son necesarios para profundizar en las implicaciones de estos cambios en el tejido venoso patológico, así como el desarrollo de posibles estrategias dirigidas a esta diana.

Jamur merupakan tanaman dari kingdom fungi dengan tubuh berdaging dan dapat dapat dimakan, meski demikian terdapat beberapa spesies jamur yang tidak dapat dimakan dan memiliki ciri khas tersendiri. Banyaknya orang yang mengkomsumsi jamur tanpa tahu apakah jamur yang dikomsumsi aman untuk dimakan atau beracun mengakibatkan banyak insiden keracunan jamur bahkan hingga meninggal. Salah satu jenis edukasi yang dapat dilakukan adalah dengan membuat sebuah alat dalam bentuk perangkat lunak untuk mengklasifikasikan jenis jamur menjadi bisa dimakan atau beracun. Salah satu jenis klasifikasi menggunakan algoritma kecerdasan buatan adalah algoritma Naïve Bayes yang mengasumsikan setiap nilai atribut yang mempengaruhi nilai kelas bersifat independen dari nilai atribut yang mempengaruhi nilai kelas lainnya. Data yang digunakan diperoleh berupa dataset berisi kriteria jamur dari UCI Machine Learning Repository yang telah dilabelkan kedalam edible dan poisionous dengan total data sebanyak 8124 data. Dataset yang digunakan akan dibagi menjadi dua masing-masing untuk data train dan data test dengan porsi 80% banding 20% dan 90% banding 10%. Klasifikasi dilakukan sebanyak empat kali dengan pembagian dua kali menggunakan categorical naïve bayes dan dua kali menggunakan multinomial naïve bayes untuk setiap porsi dataset sehingga dihasilkan 4(empat) model klasifikasi. Berdasarkan hasil evaluasi dan confusion matrix dapat dilihat bahwa model dengan naïve bayes categorical adalah yang terbaik dengan jarak  performa yang cukup besar dimana model Categorical1 dan Categorical2 mendapatkan akurasi 100% dengan 1 kesalahan prediksi kelas 0 pada model Categorical 2.

Abstract

In the development of the industrial revolution 4.0, information is increasingly showing a great influence on human life. Smartphone technology is often used to access social media and the internet. The development of smartphones, social media, and the number of internet users in the world, especially in Indonesia, are currently being misused, one of which is crime (cybercrime), such as online prostitution, human trafficking, cyberbullying, fraud, extortion, trafficking in illegal goods, drug trafficking. Cyberbullying is an act of intentionally and repeatedly attacking, insulting, or harming other people on social media, instant messenger applications or in other ways that lead to insulting SARA. The NIJ method is a method that aims to explain how the research steps will be carried out so that the flow and research steps can be identified systematically so that they can be used as guidelines for solving existing problems. The NIJ method can be applied in uncovering cases of deleted chat messages. The process of obtaining digital evidence of deleted messages from the instant messaging application "BIP" was successfully obtained by removing evidence from the perpetrator's smartphone using the National Institute Of Justice (NIJ) method.

Video is one the valid evidence if the handling process is in accordance with digital forensic procedures. Closed circuit television is a video sourse that is often used as authentic evidence in court. The authenticity of the video is something that is often doubted by certain parties. For this reason, this discusses how to detect the authenticity of video as digital evidence by comparing the original video files and tampering video files resulting from attack frame addition and attack frame delection. The media info tool is used to analyze the metadata and the localization tampering method is used to detect the frame where manipulation occurs. Localization tampering analyzes frame by frame, calculates as histogram and displays a histogram graph. Based on the results of the metadata analysis of the original video file and the video file tampering, it displays different information, which means that the video has been manipulated. Next, analyze the video with the localization tampering method to display the location on the video frame where manipulation has occurred. From the analysis results provide different information both from the calculation of the RGB value and the histogram graph.

Reflected Spectroscopy of Small Exoplanets II: Characterization of Terrestrial Exoplanets
Authors: Damiano Mario , Hu Renyu
Published: May 2022

A space telescope capable of high-contrast imaging has been recognized as the avenue toward finding terrestrial planets around nearby Sun-like stars and characterizing their potential habitability. It is thus essential to quantify the capability of reflected light spectroscopy obtained through direct imaging for terrestrial exoplanets, and existing work focused on planetary analogs of modern Earth. Here we go beyond Earth analogs and use a Bayesian retrieval algorithm, ExoReL

R

, to determine what we could learn about terrestrial exoplanets from their reflected light spectra. Recognizing the potential diversity of terrestrial exoplanets, our focus is to distinguish atmospheric scenarios without any a priori knowledge of the dominant gas. We find that, while a moderate-resolution spectrum in the optical band (0.4−1.0 μm) may sufficiently characterize a modern Earth analog, it would likely result in incorrect interpretation for planets similar to Archean Earth or having CO2-dominated atmospheres. Including observations in the near-infrared bands (1.0−1.8 μm) can prevent this error, determine the main component (N2, O2, or CO2), and quantify trace gases (H2O, O3, and CH4) of the atmosphere. These results are useful to define the science requirements and design the wavelength bandwidth and observation plans of exoplanet direct imaging missions in the future.

We present the discovery and validation of a temperate sub-Neptune around the nearby mid-M dwarf TIC 470381900 (TOI-1696), with a radius of 3.09 ± 0.11 R
⊕ and an orbital period of 2.5 days, using a combination of Transiting Exoplanets Survey Satellite (TESS) and follow-up observations using ground-based telescopes. Joint analysis of multiband photometry from TESS, Multicolor Simultaneous Camera for studying Atmospheres of Transiting exoplanets (MuSCAT), MuSCAT3, Sinistro, and KeplerCam confirmed the transit signal to be achromatic as well as refined the orbital ephemeris. High-resolution imaging with Gemini/’Alopeke and high-resolution spectroscopy with the Subaru InfraRed Doppler (IRD) confirmed that there are no stellar companions or background sources to the star. The spectroscopic observations with IRD and Infrared Telescope Facility SpeX were used to determine the stellar parameters, and it was found that the host star is an M4 dwarf with an effective temperature of T
eff = 3185 ± 76 K and a metallicity of [Fe/H] = 0.336 ± 0.060 dex. The radial velocities measured from IRD set a 2σ upper limit on the planetary mass to be 48.8 M
⊕. The large radius ratio (R
p/R
⋆ ∼ 0.1) and the relatively bright near-infrared magnitude (J = 12.2 mag) make this planet an attractive target for further follow-up observations. TOI-1696 b is one of the planets belonging to the Neptunian desert with the highest transmission spectroscopy metric discovered to date, making it an interesting candidate for atmospheric characterizations with JWST.
The bacterial hitchhiker’s guide to COI: Universal primer-based COI capture probes fail to exclude bacterial DNA, but 16S capture leaves metazoa behind
Authors: Hintikka Sanni , Carlsson Jeanette E.L. , Carlsson Jens
Published: May 2022

Environmental DNA (eDNA) metabarcoding from water samples has, in recent years, shown great promise for biodiversity monitoring. However, universal primers targeting the cytochrome oxidase I (COI) marker gene popular in metazoan studies have displayed high levels of nontarget amplification. To date, enrichment methods bypassing amplification have not been able to match the detection levels of conventional metabarcoding. This study evaluated the use of universal metabarcoding primers as capture probes to either isolate target DNA or to remove nontarget DNA, prior to amplification, by using biotinylated versions of universal metazoan and bacterial barcoding primers, namely metazoan COI (mlCOIintF) and bacterial 16S (515F). Additionally, each step of the protocol was assessed by amplifying for both metazoan COI (mlCOIintF/jgHCO2198) and bacterial 16S (515F/806R) to investigate the effect on the metazoan and bacterial communities. Bacterial read abundance increased significantly in response to the captures (COI library), while the quality of the captured DNA was also improved. The metazoan-oriented probe captured bacterial DNA in a range that was also amplifiable with the 16S primers, demonstrating the ability of capture probes to isolate fragments of DNA spanning over a longer distance than perhaps expected, from eDNA. Although the use of the tested COI probe cannot be recommended for metazoan enrichment, based on the experimental results, the concept of capturing these longer fragments could be applied to metazoan metabarcoding. By using a truly conserved site without a high-level taxonomic resolution as a target for capture, it may be possible to isolate DNA fragments large enough to span over a nearby barcoding region (e.g., COI), which can then be processed through a conventional metabarcoding-by-amplification protocol.

Influence of green tea powder on the performance, nutrient utilisation, caecal microbiota profile and meat quality of broiler chickens
Authors: Thomas D.V. , Molan A.L. , Singh Y. , Ravindran V.
Published: May 2022

This study assessed the influence of green tea powder diet supplementation on performance, nutrient utilisation, caecal microbiota profile and meat quality in broiler chickens. A total of 144, one-day-old broiler (Ross 308) chicks were allocated to 18 cages (eight broilers/cage) which were randomly assigned to one of three dietary treatments: a wheat-based basal diet or supplemented with one of two types of green tea; normal (N-GT) or selenium-rich (Se-GT) tea, at an inclusion rate of 1%. Bird performance, nitrogen-corrected apparent metabolisable energy (AMEn), and total tract digestibility of fat and starch were measured on d 7, 21 and 35. Effects on microbiota profile on d 7, 21 and 35 were determined in a cohort study. Green tea supplementation reduced (P<0.05) the weight gain and feed intake but improved (P<0.05) feed efficiency. Supplementation with N-GT increased the AMEn on d 7 and 21, and with Se-GT on d 7 (P<0.05). AMEn increased with age for all treatments. Fat digestibility increased (P<0.05) in birds fed N-GT on d 21 and Se-GT on d 7 and 21. Starch digestibility increased (P<0.05) on d 21 with N-GT supplementation and on d 7 with Se-GT supplementation. Carcass and breast meat yields were unaffected (P<0.05) by the dietary treatments. The abdominal fat pad decreased (P<0.05) in the N-GT diet and numerically in the Se- GT diet. Drip loss was less in meat from birds (P<0.05) fed both green tea treatments. Cooking loss was reduced in the Se-GT treatment (P<0.05). Dietary inclusion of green tea powder positively influenced microbiota profile, with increased (P<0.05) numbers of beneficial bacteria (Lactobacillus spp. and Bifidobacterium spp.) and reduced (P<0.05) numbers of pathogenic bacteria (Clostridium spp. and Bacteroides spp.). Differences were observed between the two green tea types, with Se-GT being more beneficial than N-GT in the positive modulation of intestinal microbiota.

Published: May 2022

A $ star \; coloring $ of a graph $ G $ is a proper vertex coloring of $ G $ such that any path of length 3 in $ G $ is not bicolored. The $ star \; chromatic \; number $ $ \chi_s(G) $ of $ G $ is the smallest integer $ k $ for which $ G $ admits a star coloring with $ k $ colors. A $ acyclic \; coloring $ of $ G $ is a proper coloring of $ G $ such that any cycle in $ G $ is not bicolored. The $ acyclic \; chromatic \; number $ of $ G $, denoted by $ a(G) $, is the minimum number of colors needed to acyclically color $ G $. In this paper, we present upper bound for the star and acyclic chromatic numbers of the generalized lexicographic product $ G[h_n] $ of graph $ G $ and disjoint graph sequence $ h_n $, where $ G $ exists a $ k- $colorful neighbor star coloring or $ k- $colorful neighbor acyclic coloring. In addition, the upper bounds are tight.

Neurobrucellosis is an uncommon serious complication of brucellosis. Diagnosis of neurobrucellosis could be difficult due to non-specific clinical and radiological findings. So, in endemic regions, neurobrucellosis should be included in the differential diagnosis list of patients with recent neurological disorders. We report an unusual case of neurobrucellosis with neurologic deficits in the central and peripheral nervous system and MRI lesions in the brainstem, spinal cord, and nerve roots Also, related articles are reviewed in the discussion section.
Critical e-learning quality factors affecting student satisfaction in a Korean medical school
Authors: Si Jihyun
Published: May 2022

Purpose: This research investigated the critical factors that affect the e-learning quality. The student satisfaction model with the five factors such as content, system, learner, instructor and interaction was proposed and empirically examined. It also investigated the relationship between the interaction and other constructs.Methods: This study used a cross sectional survey design, and convenience sampling. To examine the critical factors and their relationship, a survey of 28 items was developed based on previous studies and sent out through a learning management system to all the students (n=250) enrolled in the pre-med 1 to the medicine 3 in one medical school in Korea. The medical school delivered all the courses online due to the coronavirus disease 2019 pandemic. The collected data (n=209, 83.6%) were analyzed through structural equation modeling by using IBM AMOS ver. 26.0 and IBM SPSS ver. 26.0 (IBM Corp., Armonk, USA).Results: The determinants of e-learning student satisfaction were system, learner, instructor, and interaction qualities, which together explained 72.6% of the variance of student satisfaction and the determinants of e-learning interaction quality were content and system qualities, which together explained 62.9% of the variance of interaction quality.Conclusion: The results of this study presented practical guidelines to improve e-learning quality in terms of student satisfaction in medical education contexts. The results indicated that more efforts should be directed toward improving interaction features such as interactive teaching styles, collaborative activities, providing instructors and learners with proper training for e-learning prior to e-learning and a quality of contents, and upgrading e-learning system for better performance and service.

Facing the disruption caused by COVID-19 pandemic, the emergence of imposed and exclusive online learning revealed challenges for researchers worldwide, as of reforming curricula shortly and of collecting data accumulated by monitoring stu-dents’ commitment and academic performance. With this pool of data, this research explores grade prediction in a first-semester mechanical engineering CAD module, after testing the performance of the reform of specific curricula. A hybrid model has been created, based on 35 variables having been filtered out of statistical analysis and shown to be strongly correlated to students’ academic performance in the specif-ic online module during the first semester of the academic year 2020-2021. The hy-brid model consists of a Generalized Linear Model. It’s fitting errors are used as an extra predictor to an artificial neural network. The architecture of the neural network can be described by the following sizes: size of the input layer (36), size of the hidden layer (1) and size of the output layer (1). Since new factors are revealed to affect students’ academic achievements, the model has been trained in the 70% of the participants to predict the grade of the remaining 30%. The model has therefore been divided into three subsets, with a training set of 70% of the sample and one hidden layer predicting the test set (15%) and the validation set (15%). The final form of the trained hybrid model resulted in a coefficient of determination equal to 1 (R = 1). This means that the data fitting process resulted in a 100% success rate, in terms of associating the independent variables with the dependent variable (grade).

Published: May 2022

For a long time, the online learning (OL) was reserved for a particular group of learners: mostly older people with multiple family, work, financial and other responsibilities. These students benefited from the opportunities offered by this type of educational modality compared to traditional face-to-face education. However, the emergence of the Sars CoV virus (and its derivatives) not only generated health problems, but also affected social structures, generating various problems in the field of education The general objective of the present research is to know the perceptions and evaluations that academic teaching staff from a engineering faculty have about the emergency online teaching-learning process that occurred in the context of the COVID 19 pandemic. Based on several previous works related to online learning (OL) and recently in the literature on emergency online learning (EOL), an instrument (questionnaire) was developed and implemented with the participation of teachers from a Chilean university. The research is quantitative-descriptive and had the following specific objectives: To know about (1) the readiness of the teaching staff towards the OL and (2)  their interactions with others, to characterize (3) the use of different Self-management skills and (4) the interaction with LMS and ICTs., and (5) to know about the available resources for OL. In general, the results show that teaching staff show mastery in aspects related to self-management of learning, but a low level of motivation and readiness for OL and a "loss" in aspects related to interaction with others (students and peers). These results provide a first approximation to university teachers ' perceptions of OL and allow us to identify several aspects that should be improved.

Published: May 2022

The influence of the recovery characteristics on the switching behavior of SiC metal-oxide-semiconductor field-effect transistors (MOSFETs) with different switching speeds was investigated. A comparative analysis of the devices with different recovery characteristics revealed an increase in the turn-on loss (Eon) owing to the higher output capacitance charge (Qoss) and reverse recovery charge (Qrr) in the recovery arm. On the other hand, a higher Qoss in the recovery arm resulted in a lower turn-off loss (Eoff). In addition, an increase in Qoss and Qrr further influenced Eon and Eoff at a higher switching speed. Furthermore, a higher Qrr observed at a higher switching speed indicated a more significant impact of Qrr on Eon at a high switching speed than that of Qoss. The findings clarified in this study highlight the necessity of focusing the recovery characteristics to ensure a desirable switching loss of SiC MOSFETs.

Photoluminescence (PL) imaging provide defect and dislocation characteristics not only in a 4H silicon carbide (SiC) epilayer but also in a substrate. In this work, to detect a large-pit or a bar-shaped stacking fault (BSF) before epilayer growth, we employed PL under various detection conditions. A large-pit was detected as a dark spot on a 4H-SiC substrate due to dislocations orthogonal to a micropipe. The BSF was clearly observed as a bright rectangle by tuning the observation conditions. The finding indicates that device killing defects or dislocations should be detected as soon as possible and thus improve the yield.

A SiCNWFET device serving as a biosensor was designed and simulated using Silvaco ATLAS device simulation software. The performance of the designed device in charges sensing was investigated. The device shows the ability to recognize different interface charge values ranging from-1.10E11 to-5.10E12 cm-2 applied on the surface of the silicon carbide nanowire channel to simulate target charge biomolecules that bound to the biosensor. A significant change in the output current is observed due to the presence of different values of fixed interface charge densities. An optimum, according to the TCAD simulation, the 4H-SiC epitaxial structure has been grown. The designed device was fully fabricated on this structure and it exhibited acceptable electrical characteristics.
