Multiuser-scheduling and resource allocation using max-min technique in wireless powered communication networks
Authors: Mary Thomas Richu , Subramani Malarvizhi 
Published: July 2022

Wireless <span>powered communication network (WPCN) is a promising research area for improving network security and speed. The transmission power of the source during the uplink functions as a random variable in WPCN due to the intrinsic power transfer process, whereas it is a constant in typical cooperative networks, culminating in the signal to noise ratio of the source-access point and all the source-relay-access point being mutually correlated. As a result of the massive increase in communication devices powered by battery, the goal of prolonging their life is critical. To get the most throughput in the shortest amount of time, the best uplink and downlink time allocations were calculated. For high throughput and secrecy performance, the proportional max-min fairness algorithm was used in this paper for secure communication in hybrid relays integrated with WPCN. This method allows for multi-user scheduling with optimum targets to provide reliable hybrid outage probability, secrecy outage probability, and energy outage probability. Efficacy of the proposed system was demonstrated regarding throughput, outage probability, and confidentiality. The performance of the model was compared to that of various energy harvesting models like random user scheduling, best user scheduling, and several others, and was found to outperform them for secure transmission.</span>

Published: July 2022

Data <span>transmission in orthogonal frequency division multiplexing (OFDM) system needs source and channel coding, the transmitted data suffers from the bad effect of large peak to average power ratio (PAPR). Source code and channel codes can be joined using different joined codes. Variable length error correcting code (VLEC) is one of these joined codes. VLEC is used in mat lab simulation for image transmission in OFDM system, different VLEC code length is used and compared to find that the PAPR decreased with increasing the code length. Several techniques are used and compared for PAPR reduction. The PAPR of OFDM signal is measured for image coding with VLEC and compared with image coded by Huffman source coding and Bose-Chaudhuri-Hochquenghem (BCH) channel coding, the VLEC code decreases the data transmitted size and keep the same level of PAPR reduction with respect to data coded by Huffman and BCH code when using PAPR reduction methods.</span>

Barreiras à implementação do BIM: uma análise bibliométrica acerca das pesquisas sobre a adoção do conceito no setor AEC de 2010 a 2021
Authors: Sá Larissa Miranda , Silva Luciano Falcão da 
Published: July 2022

As discussões e pesquisas em torno do conceito de Building Information Modeling (BIM) se intensificaram nos últimos anos. Porém, a sua aplicabilidade no setor de Arquitetura, Engenharia e Construção Civil (AEC) segue escalas distintas, com particularidades que devem ser consideradas. Este trabalho reúne pesquisas relevantes relacionadas à adoção e implementação do BIM, nos escritórios e empresas do setor AEC, resultado de uma análise bibliométrica da literatura científica, publicada na última década (2010 a 2021). Objetivou-se levantar informações acerca das barreiras e dificuldades enfrentadas por esses escritórios na adoção do BIM, em um panorama particionado em seis aspectos principais: quantidade de publicações anuais; países com maior produção e citações; ocorrência de palavras-chave e grupos (clusters); quantidade de publicações por periódico ou evento; autores mais citados e autores com maior quantidade de publicações no Portfólio. Os documentos resultantes foram organizados sob dois aspectos: grupos organizados por tema principal e barreiras profissionais, operacionais e associadas. Na Pesquisa Bibliométrica, foi utilizado o método Knowledge Development Process – Constructivist (ProKnow-C), aplicado na base de dados científica Web of Science, resultando em um Portfólio Bibliográfico composto por 80 documentos. As análises revelaram disparidade relacionada ao nível de implementação do BIM, independente da nacionalidade, sobretudo para micro escritórios e empresas de pequeno porte da construção civil, e também a importância do aspecto organizacional dos escritórios nesse processo. Destacou as temáticas proeminentes da última década e apontou dificuldades e barreiras comuns na adoção e implementação do BIM.
Re-Inventing the Equity Debate: Issues in Balancing Merit with Inclusion in Leadership Selection in Federal Universities in Nigeria
Authors: Alabi Ayodeji L. 
Published: July 2022

Abstract
In the conflicting pursuit of equity, the recession of non-indigenes in leadership positions in the nation’s federal universities is a major source of campus restiveness. This opinion article, derived from empirical research, therefore aims at bringing to the fore the substance and implications of the faulty inclusion politics and the politicised merit criteria deployed towards achieving equity in leadership selection in Nigeria’s federal universities. University of Ibadan and University of Jos were purposively selected for the study being the institutions with the most recent vice-chancellors’ selection episodes riddled with identity-based conflicts in 2020/2021. In the two universities, key informant and in-depth interviews were conducted with prominent members of the respective institutions’ governing councils, staff unions, staff ethnic associations, and vice-chancellor candidates that were not appointed, all purposively selected being notable actors in the vice-chancellors’ appointments politics. With between 70% and 79% predominance of ethno-territorial indigenes in the institutions’ workforce, the original inclusion intent of Nigeria’s federal character principle was grossly handicapped in the leadership appointment politics. The merit assessment instruments deployed in vice-chancellors’ selection processes had subjective items prone to biased scoring. These unfashionably culminated in the persistent return of indigene vice-chancellors in the two institutions for forty years.
The Relevance of Sports to Preventing and Countering Youth Radicalisation and Violent Extremism in Nigeria’s Northeast
Authors: Onuoha Freedom Chukwudi , Owonikoko Saheed B. 
Published: July 2022

Abstract
The Nigerian government has relied on a kinetic approach to counter the threat of Boko Haram extremism, registering very little appreciable successes. This has underscored the need for use of soft approaches such as sports as a tool for preventing and countering violent extremism (P/CVE) in Nigeria’s northeast. This article examines two cases of community-based interventions involving sports in Borno and Adamawa states to highlight the potential relevance of sporting activities to P/CVE in Nigeria. Drawing from the initiatives, the article demonstrates that sporting activities have proven useful in promoting peacebuilding, community reconciliation, social cohesion and a sense of inclusivity and belonging among marginalised groups. It concludes that the mainstreaming of youth-focused sports-based initiatives into community development through a multi-stakeholder approach will contribute to fostering peace, social cohesion and community resilience. This, in turn, will help diminish the conditions that are conducive to youth vulnerability to recruitment and radicalisation by Violent Extremist Organisations (VEOS).
Notes on carabid beetles of the genera Coleolissus and Siopelus (Coleoptera: Carabidae: Harpalini), with description of four new species with unusual aedeagi from India and China
Authors: KATAEV BORIS M. 
Published: July 2022

New data on the taxonomy, morphology and distribution of several species of the genera Coleolissus Bates, 1892 and Siopelus Murray, 1859 from the southern Palaearctic and Oriental regions are provided, with special attention to the structure of their male genitalia. Coleolissus perlucens (Bates, 1878), originally described as Hypolithus perlucens Bates, 1878, the type species of Coleolissus, and C. iris Andrewes, 1924 are re-described based on the holotypes and the additional material. The following four new species with unusual aedeagi are described: C. kejvali sp. n., C. deformipenis sp. n., and C. monstrosipenis sp. n. from Western India, and Siopelus (Neosiopelus) liangi sp. n. from Yunnan, China. The extremely unusual shape of the aedeagus of C. monstrosipenis sp. n. is discussed. It is supposed that the highly modified apical portion of the aedeagus in this species takes over some of the mechanical functions of the internal sac during mating. The following new synonyms are proposed: Coleolissus iris Andrewes, 1924 = Calathomimus splendens Ito, 1997, syn. n. = Coleolissus turturensis Ito, 2016, syn. n. The following taxa are recorded for the first time: Coleolissus iris from the Indian states of Punjab and Kerala, and the genus Siopelus (subgenus Neosiopelus Basilewsky, 1946) from China.
Effects of Varying Land Coverage, Rotation Period, and Water Vapor on Equatorial Climates that Bridge the Gap between Earth-like and Titan-like
Authors: McKinney M. M. , Mitchell J. , Thomson S. I. 
Published: July 2022

Abstract
Saturn’s largest moon, Titan, has an Earth-like volatile cycle, but with methane playing the role of water and surface liquid reservoirs geographically isolated at high latitudes. We recreate Titan’s characteristic dry hydroclimate at the equator of an Earth-like climate model without seasons and with water as the condensable by varying a small set of planetary parameters. We use three observationally motivated criteria for Titan-like conditions at the equator: 1) the peak in surface specific humidity is not at the equator, despite it having the warmest annual-mean temperatures; 2) the vertical profile of specific humidity in the equatorial column is nearly constant through the lower troposphere; and 3) the relative humidity near the surface at the equator is significantly lower than saturation (lower than 60%). We find that simply reducing the available water at the equator does not fully reproduce Titan-like conditions. We additionally vary the rotation period and volatility of water to mimic Titan’s slower rotation and more abundant methane vapor. Longer rotation periods coupled with a dry equatorial surface meet fewer of the Titan-like criteria than equivalent experiments with shorter rotation periods. Experiments with higher volatility of water meet more criteria than those with lower volatility, with some of those with the highest volatility meeting all three, demonstrating that an Earth-like planet can display Titan-like climatology by changing only a few physical parameters.
A Theory for the Hadley Cell Descending and Ascending Edges throughout the Annual Cycle
Authors: Hill Spencer A. , Bordoni Simona , Mitchell Jonathan L. 
Published: July 2022

Abstract
We present a theory for the latitudinal extents of both Hadley cells throughout the annual cycle by combining our recent scaling for the ascending edge latitude based on low-latitude supercriticality with the theory for the poleward, descending edge latitudes of Kang and Lu based on baroclinic instability and a uniform Rossby number (Ro) within each cell’s upper branch. The resulting expressions for all three Hadley cell edges are predictive except for diagnosed values of Ro and two proportionality constants. Thermal inertia—which damps and lags the ascent latitude relative to the insolation—is accounted for semianalytically through the Mitchell et al. model of an “effective” seasonal forcing cycle. Our theory, given empirically an additional ∼1-month lag for the descending edge, captures the climatological annual cycle of the ascending and descending edges in an Earthlike simulation in an idealized aquaplanet general circulation model (GCM). In simulations in this and two other idealized GCMs with varied planetary rotation rate (Ω), the winter, descending edge of the solsticial, cross-equatorial Hadley cell scales approximately as Ω−1/2 and the summer, ascending edge as Ω−2/3, both in accordance with our theory. Possible future refinements and tests of the theory are discussed.

Authors: Matthias Anne Thushara , Kaushalya Pingamage Dona Jayamini 
Published: July 2022

Objective: This study aimed to assess the quality and readability of web-based information on familial hypercholesterolaemia. Design, setting and methods: Internet searches using the terms ‘familial hypercholesterolemia’, ‘hypercholesterolemia’, ‘inherited high cholesterol’, ‘hereditary high cholesterol’ and ‘inherited high LDL’ were conducted with the Google, Yahoo! and Bing search engines using default settings during August 2021. The first 50 web links that appeared using each search engine were evaluated using the Flesch Reading Ease Score (FRES) and DISCERN instrument for readability and the quality of the website. The LIDA tool was used to assess reliability and usability. Results: In all, 750 websites were accessed and 38 websites were included in the analysis. The majority of the websites (29, 76.3%) were owned by non-governmental institutions. Twelve (30.8%) websites were certified by the Health On the Net Foundation (HON) code of conduct. Only 17 websites (44.7%) had a stated author. Twenty-nine (76.3%) websites had a stated date of publication. Only 16 (42.1%) provided references for the statements made. Infographics were used in 17 (44.7%) websites. The median FRES was 47.15 (range: 22.3–91.8), which is equivalent to college-level readability. The median LIDA usability and reliability score was 38.00 (range: 25–46) and 15.00 (range: 7–24), respectively. The median DISCERN score was 45.00 (range: 17–76). The DISCERN score was significantly associated with the FRES (0.047) and whether the website was governmental or not (0.028). Conclusion: According to this study, the readability, reliability, usability and quality of the majority of websites were inadequate. Due to the rapid growth in the use of the Internet, steps need to be taken to standardise and regulate patient education websites for this and perhaps other health conditions.

Published: July 2022

Background: Early identification and timely management of septic AKI continue to represent clinical challenges for intensive care. The aim was to evaluate the effect of renal replacement with oXiris filter on clinical outcomes in septic AKI. Methods: This was a single-center randomized controlled trial that enrolled surgical septic shock with AKI patients admitted in the ICU, Renji Hospital, Shanghai Jiao Tong University, School of Medicine from Jan 1, 2021 to Sep 30, 2021, were screened. Results: Sixteen subjects that met the inclusion and exclusion criteria were randomized into CRRT with AN69-oXiris group ( n = 8) and AN69-ST group ( n = 8). The PCT and IL-6 concentration decreased significantly after the first treatment compared to pre-CRRT levels in the oXiris group (PCT: 23.46 [4.18, 84.90] vs 52.79 [9.03, 100.00] µg/L, p = 0.046; IL-6: 3080.15 [527.62, 9806.61] vs 10,457.17 [8150.00, 15,528.87] pg/mL, p = 0.043). The levels of lactate decreased by 1.70 [1.03, 2.83] mmol/L after the first CRRT in the oXiris group ( p = 0.028). The norepinephrine infusion rate was decreased by 0.06 [0, 0.09], 0.05 [0, 0.23] and 0.11 [0, 0.23] μg/kg/min at 4, 6, and 8 h in the oXiris group compared to the ST group ( p = 0.005, 0.038, and 0.017). Conclusion: Using the oXiris filter may improve hemodynamic status during initial CRRT in severe surgical septic shock with AKI. Further large multicenter RCTs are needed to determine the effect of the oXiris filter on patient outcomes. ( http://www.chictr.org.cn/index.aspx (ChiCTR2200055732)).

Published: July 2022

Introduction D-dimer is a small protein fragment produced during fibrinolysis. High D-dimer levels were shown to have prognostic impact in critically ill patients. Nevertheless, data regarding D-dimer's prognostic impact among tertiary care intensive coronary care unit (ICCU) patients is scarce. Material and method All patients admitted to the ICCU between 1-12/2020 were prospectively included. Based on admission D-dimer level, patients were categorized into low and high D-dimer groups (< 500 ng/ml and ≥ 500 ng/ml) and also to age-adjusted D-dimer cutoff (500 ng/ml for ages ≤ 50 years old and age*10 for ages>50 years old). Results and discussion A total of 959 consecutive patients were included, including 296 (27.4%) and 663 (61.3%) patients with low and high D-Dimer levels, respectively. Patients with high D-dimer level were older compared with patients with low D-dimer level (age 70.4 ± 15 and 59 ± 13 years, p = 0.004) and had more comorbidities. The most common primary diagnosis on admission among the low D-dimer group was acute coronary syndrome (ACS) (74.3%), while in the high D-dimer group it was a combination of ACS (33.6%), cardiac structural interventions (26.7%) and various arrhythmias (21.1%). High D-dimer levels were associated with increased mortality rate, even after adjustment for age, gender, comorbidities and left ventricular ejection fraction (LVEF). High D-dimer levels were independently associated with increased overall 1-year mortality rate (HR = 5.8; 95% CI; 1.7-19.1; p = 0.004). Conclusion Elevated D-dimer levels on admission in ICCU patients is an independently poor prognostic factor for in-hospital morbidity and 1-year overall mortality rate following hospitalization.
Bacteriological Quality and Public Health Risk of Ready-to-Eat Foods in Developing Countries: Systematic Review and Meta Analysis
Authors: Mengistu Dechasa Adare , Belami Desi Debelu , Tefera Alemayehu Aschalew , Alemeshet Asefa Yohanis 
Published: July 2022

Background: Ready-to-eat foods are foods that are consumed at the point of sale or later, without any further processing or treatment. Foodborne diseases are on the rise worldwide, involving a wide range of diseases caused by pathogenic bacteria, and are becoming a public health problem. Therefore, this study sought to identify and determine the bacteriological quality and public health risks in ready-to-eat foods in developing countries. Methods: The studies published from 2012 to 2020 were identified through systematic searches of various electronic databases such as Google Scholar, PubMed and MEDLINE, MedNar, EMBASE, CINAHL, Scopus, and Science Direct. The articles were searched using a Boolean logic operator (“AND,” “OR,” “NOT”) combination with Medical Subject Headings (MeSH) terms and keywords. All identified keywords and an index term were checked in all included databases. In addition, a quality assessment is performed to determine the relevance of the article, and then the data are extracted and analyzed. Results: The current study found that the pooled prevalence of Staphylococcus aureus, Enterobacter species, Klebsiella, Escherichia coli, Salmonella, Bacillus cereus, Pseudomonas species, and Shigella in ready-to-eat foods was 30.24% (95% CI: 18.8, 44.65), 11.3% (95% CI: 6.6, 18.7), 9.1% (95% CI: 7.0, 11.8), 23.8% (95% CI: 17.5, 31.5), 17.4% (95% CI: 11.6, 25.31)], 26.8% (95% CI: 13.7, 45.9), 6.1% (95% CI: 2.8, 12.6), 34.4% (95% CI: 18.1-55.4), respectively. Conclusions: Most of the reviewed articles reported on various pathogenic bacterial species that are potentially harmful to human health, such as Staphylococcus aureus, Salmonella, Shigella, and Escherichia coli in ready-to-eat food above the maximum allowable limit. Therefore, relevant national and international organizations must take corrective measures to prevent foodborne diseases and protect human health.
A pilot study on deep learning-based grading of corners of vertebral bodies for assessment of radiographic progression in patients with ankylosing spondylitis
Authors: Koo Bon San , Lee Jae Joon , Jung Jae-Woo , Kang Chang Ho , Joo Kyung Bin , Kim Tae-Hwan , Lee Seunghun 
Published: July 2022

Background: Radiographs are widely used to evaluate radiographic progression with modified stoke ankylosing spondylitis spinal score (mSASSS). Objective: This pilot study aimed to develop a deep learning model for grading the corners of the cervical and lumbar vertebral bodies for computer-aided detection of mSASSS in patients with ankylosing spondylitis (AS). Methods: Digital radiographic examination of the spine was performed using Discovery XR656 (GE Healthcare) and Digital Diagnost (Philips). The disk points were detected between the bodies using a key-point detection deep learning model from the image obtained in DICOM (digital imaging and communications in medicine) format from the cervical and lumbar spinal radiographs. After cropping the vertebral regions around the disk point, the lower and upper corners of the vertebral bodies were classified as grade 3 (total bony bridges) or grades 0, 1, or 2 (non-bridges). We trained a convolutional neural network model to predict the grades in the lower and upper corners of the vertebral bodies. The performance of the model was evaluated in a validation set, which was separate from the training set. Results: Among 1280 patients with AS for whom mSASSS data were available, 5,083 cervical and 5245 lumbar lateral radiographs were reviewed. The total number of corners where mSASSS was measured in the cervical and lumbar vertebrae, including the upper and lower corners, was 119,414. Among them, the number of corners in the training and validation sets was 110,088 and 9326, respectively. The mean accuracy, sensitivity, and specificity for mSASSS scoring in one corner of the vertebral body were 0.91604, 0.80288, and 0.94244, respectively. Conclusion: A high-performance deep learning model for grading the corners of the vertebral bodies was developed for the first time. This model must be improved and further validated to develop a computer-aided tool for assessing mSASSS in the future.
