Neutrophil-to-Lymphocyte Ratio (NLR) Is a Promising Predictor of Mortality and Admission to Intensive Care Unit of COVID-19 Patients

The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker predicting the prognosis of several diseases. We aimed to assess its role as a predictor of mortality or admission to the intensive care unit in COVID-19 patients. We retrospectively evaluated a cohort of 411 patients with COVID-19 infection. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP) of patients with COVID-19 were compared. The median age of our sample was 72 years (interquartile range: 70–75); 237 were males. Hypertension, diabetes and ischemic heart disease were the most common comorbidities. The study population was subdivided into three groups according to NLR tertiles. Third-tertile patients were older, showing significantly higher levels of inflammatory markers; 133 patients (32%) died during hospitalization, 81 of whom belonged to the third tertile; 79 patients (19%) were admitted to ICU. NLR showed the largest area under the curve (0.772), with the highest specificity (71.9%) and sensitivity (72.9%), whereas CRP showed lower sensitivity (60.2%) but slightly higher specificity (72.3%). Comparisons between NLR and CRP ROC curves were significantly different (p = 0.0173). Cox regression models showed that the association between NLR and death was not weakened after adjustment for confounders. Comparisons of ROC curves showed no significant differences between NLR, PLR, and CRP. Cox regression analysis showed that NLR predicted the risk of admission to ICU independently of demographic characteristics and comorbidities (HR: 3.9597, p < 0.0001). These findings provide evidence that NLR is an independent predictor of mortality and a worse outcome in COVID-19 patients and may help identify high-risk individuals with COVID-19 infection at admission.
Coaches’ opinions about teaching defensive skills for youth handball teams

Purpose It can be observed that coaching in youth sports may be based on technique development, while it is inspired by high-performance sports. As it is observed a lack of research that addressed the coaching process with youth handball teams in the Brazilian context, this study aimed to analyze what is expected for the defensive phase and how it is taught. Methods We interviewed 22 handball coaches from the U-12, U-14, U-16, and U-18 teams addressing the teaching of defensive skills when facing different offensive systems and the approaches used in the training sessions. The interviews were analyzed using the Collective Subject Discourse (CSD) method. Results and discussion The coaches’ discourses revealed an increasing expectation due to players’ experience, but with stimulation of high-level sport since the youngest teams. The discourses also emphasized the use of traditional approaches and game-based approaches to apply the learned skill in the game context, independently of the age group. It was noted that the expectations of the coaches about players’ technical-tactical development and the approaches are controversial, especially when comparing the specific skills with the use of the traditional approach in the younger teams (U-12 and U-14 teams). It is suggested that more attention must be paid when choosing the defensive skills to be taught for youth players, and the chosen teaching approaches must promote a reflexive environment to learners.
A Comparative Perspective on Long-Term Care Systems

This paper investigates challenges of aging for long-term care. Our analysis proceeds in three steps. In the first step, we estimate the prospective care demand for 30 developed countries based on projected aging and disabilities among the elderly. In the second step, we outline challenges for care systems with respect to shortages of care workers, increasing skill requirements for care workers, barriers to universal and equitable access to care, and cost containment subject to adequate care quality. In the third step, we identify solutions for these challenges by comparing the care systems of Germany, Israel, Japan, the Netherlands, and South Korea. we have Our results predict an average care of 47 percent with the largest and Eastern Our results further highlight that good population terms a low disability among the elderly—can moderate growth in care demand.
AI-based component management system for structured content creation, annotation, and publication

Nowadays, the ever changing and growing amount of information, regulations, and data requires large organizations to describe on the web increasingly complex and interdependent business processes and services, ideally creating user-profiled content that is clear and up to date. To successfully achieve this goal, as off-the-shelf solutions are missing, institutions have to embark in a digital transformation process fully endorsed by governance, led by a multidisciplinary team of experts, and strongly integrated with artificial intelligence (AI) tools. In this paper we describe how a content service platform, that integrates human processes and state-of-the-art AI services, was successfully employed in our institution (UniGe) to manage, and support a system of about 200 websites. Following a single-sourcing paradigm, its advent allowed for the decoupling of content and technology, preparing UniGe for the future needs of the semantic web.
Padmakar-Ivan Index of Some Types of Perfect Graphs

The Padmakar-Ivan (PI) index of a graph G is deﬁned as PI ( G ) = (cid:80) e ∈ E ( G ) ( | V ( G ) | − N G ( e )) , where N G ( e ) is the number of equidistant vertices for the edge e . A graph is perfect if for every induced subgraph H , the equation χ ( H ) = ω ( H ) holds, where χ ( H ) is the chromatic number and ω ( H ) is the size of a maximum clique of H . In this paper, the PI index of some types of perfect graphs is obtained. These types include co-bipartite graphs, line graphs, and prismatic graphs.
Late Holocene development of Bubiyan Island, Kuwait

Abstract Bubiyan Island, presently a vast sabkha and salt flat in the westernmost part of the Shatt Al-Arab delta, originated ca. 4000 cal yr BP as prodelta deposits from a paleochannel of the Euphrates River that flowed into a shallow sea. Southeastern Bubiyan Island first surfaced when spits and barrier islands formed on a 1–2 m forebulge caused by heavy sediment load to the northwest; the spits and barriers delineated an incipient shoreline and sheltered a shallow lagoon. Progradation of southeastern Bubiyan Island began when the spits and barriers were gradually stranded as beach ridges during minor sea-level fluctuations and continued marginal uplift. AMS dating of the beach ridges, which are ~1–5 km from the present shoreline, implies that Late Holocene relative sea level fell in three phases: ca. 3700–3400 cal yr BP, ca. 2600–1000 cal yr BP, and ca. 600–500 cal yr BP. Prior to each phase, relative sea level apparently stabilized to near stillstands, allowing spits and barriers to accrete. Torpedo-jar pottery sherds scattered on some of the most prominent beach ridges indicate Sasanian (AD ca. 300–650; 1650–1300 cal yr BP) to early Islamic (AD ca. 650–800; 1300–1150 cal yr BP) periods of human presence, concurrent with the Second phase of beach-ridge formation.
Analysis of Shielding Effectiveness of Multi-layer Steel Cages under High-Altitude Nuclear Explosion

In view of the strong electromagnetic pulse environment of high-altitude nuclear explosions, the shielding effective-ness of different structural steel cage in protection engineering is studied, which provides an effective reference for the normal operation of electronic equipment. The MoM method is used to perform coupling calculations on eight different structures of steel cages. The influence of two parameters that the number of layers and the size of the square holes on the shielding effectiveness is analyzed. And a preliminary assessment was conducted from the amount of steel bars about the two factors. The results show that increasing the number of layers of the steel cage can more effectively prevent the coupling of high-altitude nuclear explosive electromagnetic pulses into the steel cage than reducing the size of the metal mesh, but it led to more steel consumption.
A Catchment‐Based Hierarchical Spatial Tessellation Approach to a Better Representation of Land Heterogeneity for Hyper‐Resolution Land Surface Modeling

To represent the physical processes at hillslope scales for hyper‐resolution land surface modeling, we propose a hierarchical, catchment‐based spatial tessellation method. The land surface is divided into a hierarchical structure: catchments, height bands along hillslopes within a catchment, and land cover patches within a height band. This catchment‐based structure explicitly represents hillslope drainage networks and can be applied at various resolutions determined by a pre‐defined maximum height band size. The proposed tessellation method is superior to the conventional grid‐based structure in representing land surface heterogeneity, resulting in a higher aggregation skill through the height band representation. The spatial variations in air temperature, leaf area index, saturated soil hydraulic conductivity, and soil porosity are generally lower within a height band than those in a conventional rectangular grid, reflecting the nature of topographic control on climate, vegetation, and soil distribution. The improvement in aggregation skill depends on resolutions and terrain slope angle, more pronounced at 1/6° model resolution and over steeper terrains. Finally, we demonstrate that our proposed catchment‐based structure performs better than the grid‐based structure through modeling tests over the Columbia River basin at resolutions of 1/2°, 1/6°, and 1/20° and a global test at 1/2° using the ILAMB model evaluation metrics.
Prevalence of chronic kidney disease and associated factors among patients with chronic illness in Ethiopia: A systematic review and meta-analysis

Objective: The main aim of this systematic review and meta-analysis is to provide summarized evidence on the prevalence of chronic kidney disease and associated factors among patients with chronic illness in Ethiopia. Method: Databases of MEDLINE/PubMed, Embase, Google Scholar, CINAHL, Cochrane library, and ScienceDirect were searched. In addition, gray literatures were searched manually from university repositories. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was used to select potential studies. Microsoft Excel 2013 sheet template was used to extract data. The quality of included studies was assessed by utilizing the Newcastle-Ottawa Scale. STATA software version 14.0 is used to compute the estimated pooled prevalence and associated factors of chronic kidney disease. Result: Twelve articles that fulfilled the inclusion criteria were included. The pooled estimate of chronic kidney disease among patients with chronic illnesses in Ethiopia is 21.71% (95% confidence interval: 17.67, 25.74). The highest prevalence of chronic kidney disease among patients with chronic illnesses is from Oromia (32.55% (confidence interval: 19.91, 45.19)). Glomerular filtration rate showed a comparable pooled prevalence from Cockroft-Gault and MDRD methods; 22.38% (confidence interval: 15.83, 28.92), 22.18 (confidence interval: 18.01, 26.34), respectively. Hypertensives become more likely to have chronic kidney disease compared with normotensive patients, (odds ratio = 3.01, 95% confidence interval: 1.33, 6.81). Conclusion: Prevalence of chronic kidney disease among chronic illness patients was significantly high. Hypertension is significantly associated with chronic kidney disease. Hence, we recommend that continuous screening of possible risk factors and proper follow-up and management strategies should be designed.
Experimental Investigation of the Effect of Fired Clay Brick on Partial Replacement of Rice Husk Ash (RHA) with Brick Clay

Clay bricks are more popular in building constructions than the cement/concrete bricks because of eco-friendly and low cost. These bricks have been made from clay, since they found. However, the quality of the bricks can be upgraded by doping with the agricultural natural waste materials. Rice husk (RH), is a most common and hugely abundant wastes that consist of SiO2 percentage is RHA. In the present study, eight sets of brick were manufactured and each set consists of three bricks. These bricks were doped with RHA of ratio 0 to 30% of the total weight of mixture with a step of 5%. These bricks were allowed to dry for 3 days and fired in the brick kiln, which the traditional method is still used to burn bricks in Sri Lanka. The physical and mechanical properties of the burnt bricks were tested and compared with Sri Lankan Standard Specifications (S.L.S) as well as the British Standard Specifications (B.S.S) and compared with the commercially available brick made purely from clay. The bricks doped with RHA are obviously superior to the commercially available brick in the Eastern region of Sri Lanka. However, the brick doped with 5% RHA has higher compressibility of 3.7 N.mm-2 and the water absorption of 15.8% that satisfy the S.L. S and B.S.S.
22 nm In 0.75 Ga 0.25 As channel-based HEMTs on InP/GaAs substrates for future THz applications

In this work, the performance of L g = 22 nm In 0.75 Ga 0.25 As channel-based high electron mobility transistor (HEMT) on InP substrate is compared with metamorphic high electron mobility transistor (MHEMT) on GaAs substrate. The devices features heavily doped In 0.6 Ga 0.4 As source/drain (S/D) regions, Si double δ-doping planar sheets on either side of the In 0.75 Ga 0.25 As channel layer to enhance the transconductance, and buried Pt metal gate technology for reducing short channel effects. The TCAD simulation results show that the InP HEMT performance is superior to GaAs MHEMT in terms of f T , f max and transconductance ( g m _ max ). The 22 nm InP HEMT shows an f T of 733 GHz and an f max of 1340 GHz where as in GaAs MHEMT it is 644 GHz and 924 GHz, respectively. InGaAs channel-based HEMTs on InP/GaAs substrates are suitable for future sub-millimeter and millimeter wave applications.
Clinical Efficacy of Ulinastatin Combined with Meglumine Adenosine Cyclophosphate in the Treatment of Acute Myocardial Infarction

Ulinastatin, a common adjuvant drug in the clinical treatment of acute circulatory failure, has a good effect on various inflammatory diseases. In this study, we aim to explore the clinical efficacy of ulinastatin combined with meglumine adenosine cyclophosphate in patients with acute myocardial infarction (AMI) and its effect on cardiac function and endothelial function of patients. 100 AMI patients treated in our hospital (February 2020-October 2020) were randomly chosen and divided into group J and group Q, with 50 cases in each group. Group Q was treated with meglumine adenosine cyclophosphate only, while group J was treated with ulinastatin combined with meglumine adenosine cyclophosphate to compare the treatment efficiency, cardiac structure indexes, cardiac systolic function, blood lipid levels, vascular endothelial function, QLI (quality of life) scores, BI indexes, and FMA (motor function) scores between the two groups. The treatment efficiency, QLI score, BI index, and FMA score in group J were notably higher compared with group Q (P < 0.05). The cardiac structure indexes, cardiac systolic function, blood lipid level, and vascular endothelial function in group J were notably better compared with group Q (P < 0.05). Ulinastatin combined with meglumine adenosine cyclophosphate can obviously enhance the therapeutic effect of AMI patients and improve the endothelial function and cardiac function of patients, which is very promising in this medical area.

The Effectiveness of Learning to Use HMD-Based VR Technologies on Nursing Students: Chemoport Insertion Surgery

Background: The purpose of this study was to develop a mobile head mounted display (HMD)-based virtual reality (VR) nursing education program (VRP), and to evaluate the effects on knowledge, learning attitude, satisfaction with self-practice, and learning motivation in nursing students. Methods: This was a quasi-experimental study using a nonequivalent control group pretest-posttest design to evaluate the effects of HMD-based VRP on nursing students. A Chemoport insertion surgery nursing scenario was developed with HMD-based VRP. The experimental group consisting of 30 nursing students underwent pre-debriefing, followed by VRP using HMD and debriefing. The control group, consisting of 30 nursing students, underwent pre-debriefing, followed by self-learning using handouts about Chemoport insertion surgery procedures for 30 min, and debriefing. Results: The experimental group that underwent HMD-based VRP showed significantly improved post-intervention knowledge on operating nursing (p = 0.001), learning attitude (p = 0.002), and satisfaction (p = 0.017) compared to the control group. Sub-domains of motivation, attention (p < 0.05), and relevance (p < 0.05) were significantly different between the two groups, post-intervention. Conclusions: HMD-based VRP of Chemoport insertion surgery is expected to contribute to knowledge, learning attitude, satisfaction, attention, and relevance in nursing students.

Broadband SIW cavity-backed antenna with Orthog-onal T-shaped slot and I-shaped slot

A broadband planar substrate integrated wave-guide cavity-backed slot antenna working at Ku band is demon-strated in this article. An I-shaped slot, a T-shaped slot and two symmetrical L-shaped slots are designed to expand bandwidth. The antenna can operate at 12.78GHz-16.82GHz with the fractional bandwidth of 27%, while it keeps a stable radiation charac-teristics. The peak gain of the antenna is 6.26dB. These excellent performances make the proposed antenna suitable for the broad-band application of Ku band.
Ultra Wideband Channel Measurement and Analysis for Low Altitude UAV Air-to-Ground Scenario

Evaluating and accurately modeling unmanned aerial vehicle (UAV) channel model have a significant impact on the design of UAV wireless communication networks. In this pa-per we present an ultra wideband (UWB) channel measurement campaign for low altitude UAV air-to-ground (A2G) scenario. Both line-of-sight (LOS) and non line-of-sight (NLOS) scenarios are considered where the UAV locates at positions with different vertical heights and horizontal places. Based on the channel measurement data, we compare four path loss models to analyze the large scale fading characteristics: the free-space path loss (FSPL) model, the log-distance path loss model (PLM), the 3GPP model and the alpha-beta-gamma (ABG) model. Further, the shadowing fading (SF) is also studied in order to evaluate the impact of blockage by human body on channel characteristics. The result shows that the ABG model has a higher fitting degree, and the maximum shadow fading in the NLOS scenario is twice as much as in the LOS scenario. The conclusion of the paper can be applied in the design and evaluation of UAV communications.
The Complexity of Contextuality: A Case Study on Vertical Housing Facilities in Surabaya, Indonesia

Vertical housing has been considered an effective way to provide low-income housing in many megacities. As part of an effort to implement contextual architectural design, vertical housing projects in Surabaya, East Java, Indonesia, incorporated shared kitchens and bathrooms as observed in Indonesian kampong (slum) settlements. However, the residents eventually converted their shared kitchen spaces to other uses and constructed kitchens in their individual units. This research study investigated the nature of and reasons for such transformations through quantitative and qualitative data collection among residents of three vertical housing projects in Surabaya. We found that disputes over upkeep and rules of use, along with perceived invasions of privacy, precipitated the abandonment of shared kitchens. Residents could not retrofit their shared bathrooms for structural reasons, but they renegotiated a payment system (based on flat fees rather than actual usage) that they considered unfair. Interviews revealed significant differences in implementation between the shared facilities in vertical housing and the voluntary shared arrangements in the kampongs. The facility and management modifications that occurred in vertical housing, which applied bottom-up contextual design by considering users’ needs and sensitivities, indicate the complexity of applying a contextual design process into practice.
