Diversity characteristics of four‐element ring slot‐based MIMO antenna for sub‐6‐GHz applications
Authors: Kaushal Vipul , Birwal Amit , Patel Kamlesh 
Published: March 2023

AbstractThis paper proposes four‐ring slot resonator‐based MIMO antennas of 75 × 150 mm2 without and with CSRR structures in the sub‐6‐GHz range. These orthogonal‐fed antennas have shown diverse characteristics with dual polarization. L‐shaped parasitic structures have increased the isolation (i.e., >40 dB) in the single‐element antenna over the band of 3.4 GHz–3.8 GHz. A set of three CSRR structures in the MIMO antenna reduced the coupling between antenna ports placed in an inline arrangement and enhanced the isolation from 12 dB to 20 dB and the diversity characteristics. The S‐parameters of both MIMO antennas are measured and used to evaluate MIMO parameters like ECC, TARC, MEG, and channel capacity loss. The simulation results show the variations in the gain and directivity on exciting linear and dual polarizations. The diversity performance of the reported MIMO antennas is suitable for 5G applications.

Published: March 2023

ABSTRACT Unimodal systems have limited information that can be used for identity recognition systems. The multimodal system was created to improve the unimodal system. The multimodal system used in this study is the combination of the face and palms at the matching score level. Matching scores is done using the Weighted Sum Rule method. Extract features from each sample using the Local Binary Pattern (LBP) method. Meanwhile, large data dimensions are reduced by using the Principal Component Analysis (PCA) method. The distance between face and palm data is measured using the closest distance, namely the Euclidean Distance method. Benchmark dataset using ORL, FERET and PolyU. Based on testing on each database, an accuracy rate of 98% (ORL and PolyU) and 95% (FERET and PolyU) is obtained. The test results show that the multimodal system using the Hybrid method (PCA and LBP) biometric system runs well and optimally. Keywords: Artificial intelegency, recognition, LBP, multimodal

Recently, data have been published on the leading role of endothelial dysfunction in the development of severe COVID-19, including acute renal failure (AKI) and poor prognosis in this group of patients.Aim. To define the role of angiopoetin-1(Ang-1) as a marker of endothelial dysfunction in development of AKI in patients, hospitalized with COVID-19.Materials and methods. 76 patients with confirmed coronavirus infection were included in the study. AKI was diagnosed according to KDIGO 2012 criteria in 44 patients (group 1), 32 patients without sings of kidney disfunction were in group 2. Beside standard clinical and laboratory markers on admission we evaluated serum Ang-1 level with ELISA. We used regression analysis for AKI risk factors evaluation, we calculated odds ratio (OR) and 95% confidence intervals (CI). We used Cox regression for evaluation of risk of death.Results. The serum level of angiopoietin-1 was significantly higher in patients with COVID-19 with AKI: 1.8 (1.5; 2.1) ng/ml vs 1.58 (1.29; 1.7) ng/ml in group 2, р < 0.01. In deceased patients, the level of Ang-1 at admission was significantly higher than in patients who was discharged: 1.91 (1.71; 2.32) ng/ml vs 1.58 (1.34; 1.67) ng/ml, respectively, p = 0.0001. In unifactorial regression analysis we confirmed, that increase of serum Ang-1 level >1.66 ng/ml on admission is the risk factor for AKI development in patients with COVID-19 (OR 5.7, 95% CI 1.7–19.1, р < 0.01). In Cox regression development of AKI increased the absolute risk of death: Hazard ratio = 5.159 (95% CI 1.839–14.469), p = 0.002.Conclusion. The high serum level of Ang-1 in patients with COVID-19 at hospital admission is the marker of systemic endothelial dysfunction and the risk factor for AKI and poor prognosis.

Published: March 2023

IntroductionFunctional electrical stimulation is one of the latest emerging trends in the field of electrotherapy in physiotherapy practice. It is nowadays used as an orthotic device for functional activity. The study aimed to determine the effectiveness of functional electrical stimulation in spasticity of lower extremity in spinal cord injury patients.MethodsWe conducted a qualitative systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The systematic literature search covered articles published in years 2000–2020. The databases considered for the literature search were PubMed, Cochrane, ScienceDirect, and Google Scholar. The Medical Subject Headings (MeSH) applied for the search included "functional electrical stimulation", "lower limb", "rehabilitation", "spasticity", "spinal cord injury". The records were assessed for the risk of bias with the RoB 2 Cochrane tool.ResultsThe statistical evidence suggests functional electrical stimulation to be equivalent to other modes of treatment. The overall observation of the within-group results and the feedback from the patients indicate that functional electrical stimulation is superior to all other interventions in improving the functional activities of daily life.ConclusionsFrom the evidence collected within the limitations of the present systematic review, it can be concluded that the effectiveness of functional electrical stimulation allows to apply it as an adjunct to the standard treatments available with more priority.

Published: March 2023

Introduction: In this study, we aimed to investigate the relationship between the preprocedural logistic clinical SYNTAX score (Log CSS) and major cardiovascular events (MACE) in patients with true bifurcation lesions who underwent revascularization with the double stent strategy.
Patients and Methods: A total of 233 non-ST elevation myocardial infarction (NSTEMI) patients who underwent revascularization with a double stent strategy were retrospectively included in the study. Anatomical SYNTAX score (SS) and log CSS were calculated. The patients were divided into two groups according to the cut-off value determined by ROC analysis. The prediction of two-year MACE with Log CSS was evaluated.
Results: MACE developed in 33.9% of patients with high Log CSS and 8.5% of patients with low Log CSS (p< 0.001). In the Kaplan-Meier survival analysis, the long-term survival of the high Log CSS patients was significantly lower than the low Log CSS group (Log-rank p< 0.001). In multivariate COX analyses, high Log CCS (HR= 3.781; 95% CI= 1.706-8.377; p= 0.001) was the strongest independent predictor of MACE.
Conclusion: Log CSS can be a simple and useful tool to predict the development of MACE in patients with true bifurcation lesions revascularized by percutaneous coronary intervention.
The Predictive Value of C-Reactive ProteinAlbumin Ratio in Long-Term Mortality Among Patients Undergoing Carotid Artery Stenting
Authors: Toprak Cüneyt 
Published: March 2023

Introduction: Several inflammatory biomarkers reported in previous research have been associated with the severity of carotid artery stenosis, symptomatic carotid lesions, and carotid stent restenosis. The C-reactive protein (CRP)-to-serum albumin ratio (CAR) has been shown to predict peripheral artery disease severity in patients with carotid artery disease (CAD). However, the relationship between CAR and long-term mortality in CAD patients following carotid artery stenting (CAS) remains uncertain. The goal of this study was to investigate the ability of CAR to predict long-term mortality in patients with CAS.
Patients and Methods: A total of 998 CAD patients who had percutaneous carotid artery intervention were reviewed retrospectively, and 482 of them without follow-up data were excluded from this study. The study included patients who had percutaneous carotid artery intervention between 2012 and 2018. Before the procedure, serum CRP, complete blood counts, and albumin levels were measured. The relationships between patients’ characteristics, procedural details, and CAR with all-cause mortality were evaluated in the long-term follow-up after CAS.
Results: Older age (HR= 1.044; 95% CI= 1.001-1.089; p= 0.046), smoking (HR= 2.636; 95% CI= 1.213- 5.728; p= 0.014), blood urea (HR= 1.017; 95% CI= 1.002-1.033; p= 0.025), albumin (HR= 0.252; 95% CI= 0.132-0.480; p< 0.001), CRP levels (HR= 1.336; 95% CI= 1.055-1.691; p= 0.016) and CAR (HR= 1.012; 95% CI= 1.003-1.022; p= 0.008) were statistically associated with all-cause mortality at 55.2 ± 12.4 months follow-up after CAS in multivariate COX regression analysis.
Conclusion: In patients undergoing CAS, CAR was independently related to long-term mortality. CAR could be used in this population for risk stratification to achieve closer follow-up and optimize treatment.

Exploring Non-Gaussian Sea Ice Characteristics via Observing System Simulation Experiments
Authors: Riedel Christopher , Anderson Jeffrey 
Published: March 2023

Abstract. The Arctic is warming at a faster rate compared to the globe on average, commonly referred to as Arctic amplification. Sea ice has been linked to Arctic amplification and gathered attention recently due to the decline in summer sea ice extent. Data assimilation (DA) is the act of combining observations with prior forecasts to obtain a more accurate model state. Sea ice poses a unique challenge for DA because sea ice variables have bounded distributions, leading to non-Gaussian distributions. The non-Gaussian nature violates Gaussian assumptions built into DA algorithms. This study configures different observing system simulated experiments (OSSEs) to find the optimal sea ice and snow observation subset for assimilation to produce the most accurate analyses and forecasts. Findings indicate that not assimilating sea ice concentration observations while assimilating snow depth observation produced the best sea ice and snow forecasts. A simplified DA experiment helped demonstrate that the DA solution is biased when assimilating sea ice concentration observations. The biased DA solution is related to the observation error distribution being a truncated normal distribution and the assumed observation likelihood is normal for the DA method. Additional OSSEs show that using a non-parametric DA method does not alleviate the non-Gaussian effects of the sea ice concentration observations, and assimilating sea ice surface temperatures have a positive impact on snow updates. Lastly, it is shown that perturbed sea ice model parameters, used to create additional ensemble spread in the free forecasts, lead to a year-long negative snow volume bias.

Children’s literature has always been created and published due to its importance to the aesthetical, cultural, and educational needs of young brains. It is purposefully written not only for pleasure and fun but also to teach fundamental socio-cultural values and develop early academic concepts. A voluminous juvenile literature has been produced in the English language for more than a century. However, it was dominated by British-American culture in its context, structure, vocabulary, presentation and even illustration. On the other hand, the growing number of immigrants and children who read English stories worldwide, either for learning or fun, felt it hard to relate themselves to the cultural settings of these stories. Eventually, this need drove giant publishers like Oxford, Cambridge, Macmillan, Scholastic Inc., and others to incorporate diversity and multi-ethnicity in their publications, rather than to make them Euro-American-centric. In general, Muslims—being a significant community in English speaking world—have been striving to maintain their religious identity, while attempting to assimilate into the majority culture. In addition to their various endeavours, from the dawn of the twenty-first century a significant number of women have started writing various fictional, non-fictional, illustrated, and non-illustrated books for children of different ages. In this context, this study provides an overview of women’s contributions to the promulgation of Islamic culture and civilization, using the children’s literature in the English language as their tool.

Published: March 2023

OBJECTIVES: Mental well-being is critical to quality of life. Workplace mental well-being is crucial to ensure employee health, satisfaction, and performance. Mental ill-health is a global challenge, costing workplaces $17 billion per year. Workplaces have realized the need for investment in interventions to promote mental health and well-being in their workforce. However, given their limited resources, workplace personnel responsible for program implementation need evidence-based guidance on which interventions influence which outcomes.
METHODS: This study employed a scoping review methodology in order to produce an evidence map and includes reviews of workplace mental well-being interventions. The search strategy focused on peer-reviewed articles with the primary aim of investigating workplace mental health interventions. Reviews were assessed for quality using AMSTAR 2. The evidence map includes interventions (rows) and outcomes (columns), with the relative size of the reviews underpinning each intersection represented by circles and the direction of evidence represented by color.
RESULTS: Eighty reviews were deemed eligible from 4795 citations. The resulting evidence map includes 17 intervention types designed to influence 12 outcomes. Interventions with the highest quality evidence were mindfulness, education and information provision, and individual psychological therapies. The most common outcomes were burnout / stress reduction and mental well-being. Interventions tended to focus on individual level factors rather than organizational or system-level factors.
CONCLUSION: The evidence-base for workplace mental health interventions is broad and extensive. There is an apparent knowledge-to-practice gap, presenting challenges to implementing workplace mental health programs (ie, what interventions have the highest quality evidence). This study aims to fill the gap by providing an interactive evidence-map. Future research should look to fill the gaps within the map including the lack of organization and system level factors and especially economic evaluations.

Published: March 2023

We developed an interactive web-based, decision support application that can adapt to the rapid pace of change in region-specific pandemic related variables and knowledge, thereby providing timely, accurate insights to inform a large healthcare system’s proactive response to COVID-19 hospital resource planning. We designed the COVID-19 Utilization and Resource Visualization Engine (CURVE) app to be adaptable to real-time changes as the pandemic evolved, enabling decisions to be supported by contemporary local data and accurate predictive models. To demonstrate this flexibility, we sequentially implemented a Susceptible-Infected-Removed (SIR) model that incorporates social-distancing and imperfect detection (SIR-D2), an extended-state-space Bayesian SIR model (eSIR), and a time-series model (ARIMA). CURVE improves upon other pandemic forecasting solutions by providing adaptable decision support that generates locally calibrated forecasts aligned to health system specific data to guide COVID-19 pandemic planning. The app additionally enables systematic monitoring of forecast model performance and realignment that keeps pace with the pandemic’s volatile spread and behavior. CURVE provides a flexible pandemic decision support framework that places the most accurate, locally relevant information in front of decision makers to enable health systems to be proactive and prepared.

Authors: Anggarini Dwi Wening 
Published: March 2023

Background: As a leading cause of visual impairment in elderly, age-related macular degeneration has an increasing global incidence annually. It’s association towards cataract surgery remains a debate.
Aim: The objective of this study is to summarize and evaluate the association between cataract surgery and age-related macular degeneration.
Methods: A systematic search strategy was conducted across several electronic reference databases (PubMed, Cochrane Library, ProQuest) and included articles published between 2018–2023. Duplicate publications, review articles, and incomplete articles were excluded.
Results: Databases searching identified a total of 254 articles. Of these, 29 articles passed the screening process and resulted in 12 articles for full-text assessment. The 6 articles did not evaluate the outcome of interest. Hence, we found six appropriate studies included in this review.
Conclusion: The results suggest that there may be an association of cataract surgery and increased risk of AMD progression and development. This association may increase according to the time of follow-up since cataract surgery. To improve medical treatment and for patients with cataract and AMD, additional research is essential to increase understanding of the disease state and its impact on AMD progression mainly prospective multicenter and RCT studies.
