Enhancing isolation of antenna arrays by simultaneously blocking and guiding magnetic field lines using magnetic metamaterials

In this article, we propose to enhance the isolation of antenna arrays by manipulating the near-field magnetic coupling between adjacent antennas using magnetic metamaterials (MMs). Due to the artificially designed negative or large permeability, MMs can concentrate or block the magnetic field lines where they are located, which allows us to tune the near-field magnetic coupling strengths between antennas. MMs can play a two-fold role in enhancing antenna isolation. On one hand, the magnetic fields can be blocked in gaps between adjacent antennas using MMs with negative permeability; on the other hand, the magnetic fields can be pulled towards the borders of the antenna array using MMs with large permeability. As an example, we demonstrated a four-element patch antenna array with split-ring resonators (SRR) integrated in the substrate. The measured results show that the isolation can be enhanced by more than 10 dB with the integration of SRRs, even if the gap between antennas is only about 0. 082λ. This wo.
COVID-19 Serological Status in Beta-thalassemia Patients in Iran: A Retrospective Descriptive Study

Background: Patients with beta-thalassemia (BT) are more prone to infections than others, especially when they have some risk factors. Some reports showed the lower severity of Coronavirus disease 2019 (COVID-19) infection in this population. Objectives: In this study, we aimed to determine the serological status of COVID-19 in BT patients. Methods: This cross-sectional study was conducted in September 2020-February 2021 at Ali-Asghar Children's Hospital, Iran. All major and intermedia β-thalassemia patients dependent on blood transfusion were enrolled in this study. Demographic information, including age, gender, thalassemia type, history of splenectomy, and blood type, were recorded in a checklist. Moreover, the patients were asked about their exposure to COVID-19, and the related symptoms, such as cough, fever, headache, and anosmia, in the last six months. The enrolled cases were examined for anti-COVID-19 IgM and IgG to determine the serological status against this virus. Results: The positive IgG and IgM tests against COVID-19 were in 35.7% (25/70) and 20% (14/70) of cases, respectively, while 42.9% (30/70) were either IgM- or IgG-positive. Among the serologically positive cases, six had a history of at least one symptom suspicious of COVID-19. These six included one fever, two coughs, one anosmia, one dyspnea, and one cough and anosmia. Only one of the patients was hospitalized (1%) with fever and dyspnea. No Intensive Care Unit admission or mortality was reported. Conclusions: It seems that COVID-19 is more likely to be mild or asymptomatic in patients with BT.
Binding of respiratory syncytial virus particles to platelets does not result in their degranulation in vitro

Respiratory syncytial virus (RSV) is a major cause of severe respiratory infection in infants and the elderly. The mechanisms behind severe RSV disease are incompletely understood, but a dysregulated immune response probably plays an important role. Platelets are increasingly being recognized as immune cells and are involved in the pathology of several viruses. The release of chemokines from platelets upon activation may attract, for example, neutrophils to the site of infection, which is a hallmark of RSV pathology. In addition, since RSV infections are sometimes associated with cardiovascular events and platelets express several known RSV receptors, we investigated the effect of RSV exposure on platelet degranulation. Washed human platelets were incubated with sucrose-purified RSV particles. P-selectin and CD63 surface expression and CCL5 secretion were measured to assess platelet degranulation. We found that platelets bind and internalize RSV particles, but this does not result in degranulation. Our results suggest that platelets do not play a direct role in RSV pathology by releasing chemokines to attract inflammatory cells.
Analytical analysis and linearity performance of dual metal high‐K Schottky nanowire FET(DM‐HK‐SNWFET)

This study's objectives are to deliver a relative analysis of non‐uniformly doped (NUD) and uniformly doped Dual Metal High‐K Schottky nanowire FET (DM‐HK‐SNWFET). Surface potential, subthreshold current, subthreshold swing, and drain current have been expressed and analyzed by resolving 2D Poisson's equation with suitable boundary conditions. The analog performance of the device is verified by examining cut‐off frequency (fT), trans‐conductance frequency product (TFP), gain frequency product (GFP), and gain trans‐conductance frequency product (GTFP). The results show suitable RF circuit parameters with a high switching ratio (≈3 × 109) and low subthreshold swing (61 mV/decade) for NUD‐DM‐HK‐SNWFET. Additionally, linearity frequency of merits (FOMs) and distortion performance are also studied by numerically calculating higher order voltage and current intercept point (VIP2, VIP3, IIP3, IMD3); 1‐dB compression point and Harmonics distortions (HD2 and HD3) using transconductance (gm1) along with its higher derivatives gm2 and gm3. These parameters exhibit high‐level linearity and low‐level distortion at zero crossover points in NUD‐DM‐HK‐SNWFET, making it a better contender for low‐power and high‐performance applications.
Immunodiagnosis — the promise of personalized immunotherapy

Immunotherapy showed remarkable efficacy in several cancer types. However, the majority of patients do not benefit from immunotherapy. Evaluating tumor heterogeneity and immune status before treatment is key to identifying patients that are more likely to respond to immunotherapy. Demographic characteristics (such as sex, age, and race), immune status, and specific biomarkers all contribute to response to immunotherapy. A comprehensive immunodiagnostic model integrating all these three dimensions by artificial intelligence would provide valuable information for predicting treatment response. Here, we coined the term “immunodiagnosis” to describe the blueprint of the immunodiagnostic model. We illustrated the features that should be included in immunodiagnostic model and the strategy of constructing the immunodiagnostic model. Lastly, we discussed the incorporation of this immunodiagnosis model in clinical practice in hopes of improving the prognosis of tumor immunotherapy.
Seasonal Forest Changes of Color and Temperature: Effects on the Mood and Physiological State of University Students

In this study, we attempted to analyze the effect of color and temperature changes in the forest environment over time on the mood and physiological state of university students. The survey was conducted four times considering forest changes such as new leaf appearance and growth, autumn leaf changes, and fallen leaves. The participants’ moods and physiological states were first evaluated in an indoor environment; a second evaluation was conducted after contact with the forest. The color visual information of the forest environment was analyzed through color extraction from photographs taken each survey day. The participants’ moods and physiological states were measured using the Korean Profile of Mood States-Brief and a heart rate variability measuring device, respectively. Changes in the forest experience according to the season had an effect on university students’ mood states. In particular, the effects of the spring forest experience included the relaxation of tension and the activation of vigor. This result is considered to be influenced by factors such as the season’s temperature and the green color, which is predominant in the spring forest. However, no physiological changes were found in the participants according to each season. The results of this study can lead to greater consideration of the role of color in urban forest planning for universities and other public spaces.
The Effect of Biochar Addition on Thermal Stability and Decomposition Mechanism of Poly(butylene succinate) Bionanocomposites

In the present study, poly(butylene succinate) (PBSu) and its bionanocomposites containing 1, 2.5, and 5 wt. % biochar (MSP700) were prepared via in situ melt polycondensation in order to investigate the thermal stability and decomposition mechanism of the materials. X-ray photoelectron spectroscopy (XPS) measurements were carried out to analyze the surface area of a biochar sample and PBSu/biochar nanocomposites. From XPS, it was found that only physical interactions were taking place between PBSu matrix and biochar nanoadditive. Thermal stability, decomposition kinetics, and the decomposition mechanism of the pristine PBSu and PBSu/biochar nanocomposites were thoroughly studied by thermogravimetric analysis (TGA) and pyrolysis–gas chromatography/mass spectrometry (Py−GC/MS). TGA thermograms depicted that all materials had high thermal stability, since their decomposition started at around 300 °C. However, results indicated a slight reduction in the thermal stability of the PBSu biochar nanocomposites because of the potential catalytic impact of biochar. Py−GC/MS analysis was employed to examine, in more detail, the thermal degradation mechanism of PBSu nanocomposites filled with biochar. From the decomposition products identified by Py−GC/MS after pyrolysis at 450 °C, it was found that the decomposition pathway of the PBSu/biochar nanocomposites took place mainly via β-hydrogen bond scission, which is similar to that which took place for neat PBSu. However, at higher biochar content (5 wt.%), some localized differences in the intensity of the peaks of some specific thermal degradation products could be recognized, indicating that α-hydrogen bond scission was also taking place. A study of the thermal stability and decomposition pathway of PBSu/biochar bionanocomposites is crucial to examine if the new materials fulfill the requirements for further investigation for mulch films in agriculture or in electronics as possible applications.

Growth and High-Performance Photodetectors of CsPbBr3 Single Crystals

Organic–inorganic hybrid perovskites have demonstrated exceptional photovoltaic properties, making them highly promising for solar cells and photodetectors (PDs). However, the organic components of these materials are vulnerable to heat and strong light illumination, limiting their application prospects. All-inorganic cesium-based perovskite PDs, on the other hand, possess enhanced thermal tolerance and stability, making them ideal for perovskite applications. The utilization of a ternary mixture solvent and additives in combination with single crystal (SC) growth has enabled the production of highly crystalline SCs with a defect density of 3.79 × 109 cm–3. The performance of the SC PDs had been evaluated using metal–semiconductor–metal devices, which demonstrated excellent results with a dark current as low as 0.198 μA at 10 V bias, on–off ratios exceeding 103, and a response time of shorter than 1 ms.
From Pamphlet to Utopian Caliphate: Utilization of Mass Media and Promotion of the Caliphate Ideology among Muslim Youth in Solo

The ideology of the caliphate is being intensely discussed in the Indonesian Muslim community, following the appearance of the Khilafatul Muslimin (KM) convoy that invites to welcome the emergence of the caliphate. This study focuses on examining the response of Muslim youth in Solo to the ideas of the caliphate, which are widely mushrooming in the mass media, especially in the Kaffah bulletin, one of the bulletins that disseminate the caliphate ideology on various platforms. This research uses the descriptive qualitative method, which provides descriptive data from the analysis results on the Kaffah in as many as 256 editions. The data collection technique used in this research is critical content analysis, interview, focus group discussion, and documentation. This paper argues that Kaffah has successfully promoted and mobilized young people to be attracted to the idea of the caliphate because they could neatly package religious doctrines with the hot issues being discussed. However, in brainwashing the public through the pamphlet, Kaffah is frequently questionable, quoting dhaif hadiths, distorting opinions, and utilizing fake news to support statements propagated by their affiliates.
Quality and Content Concordance of International Clinical Guidelines on Hypertensive Disorders of Pregnancy Using the AGREE II Instrument: An Updated Systematic Review

Utilization of high-quality clinical practice guidelines has the potential to positively impact health outcomes. This study aimed to assess the quality and content concordance of national and international recommendations on hypertensive disorders of pregnancy (HDPs). Searches were conducted of the MEDLINE database and reference lists generated from national and international agencies. Covidence software was used for the management of the systematic review process, the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool was used to assess guidelines for quality, and three reviewers independently screened records. The research team identified and screened a total of 399 records of which 10 were deemed high quality. Guidelines were assessed and compared regarding the treatment, prevention, and categorization of disorders. The quality of guidelines varied across different domains, with significant variation in domain scores even within individual guidelines. Not all recommendations showed a high level of methodologic rigor, and the highest-rated guidelines were from the American Heart Association, the World Health Organization, and South Africa national guidelines. Classification of hypertension differed among the guidelines, particularly in defining chronic hypertension, severe hypertension, and preeclampsia. Prevention modalities varied across guidelines, with recommendations for aspirin, calcium supplementation, and against the use of certain approaches. Treatment modalities highlighted the importance of delivery as the definitive way to terminate hypertensive disorders of pregnancy, with other management strategies provided for symptom control. The variability in guidelines and consensus statements across different contexts may reflect regional differences in healthcare practices, available resources, and research evidence. There is potential to harmonize guidelines for HDP globally while considering the unique needs of individual countries. Where guidelines may be synthesized and condensed into an accessible format, doing so could improve their use in clinical decision-making.
Effects of Aquatic Interventions on Physical Health Indicators in People with Intellectual Disabilities: A Review

Exercise in water is widely used for improving the physical capacities of people with intellectual disabilities (IDs). In this review, we examined the results of studies on the effects of water interventions on functional abilities, as well as the physiological and biochemical status of people with IDs. We considered studies in the PubMed, MEDLINE, Scopus, Google Scholar, and Research Gate databases which were published between 2010 and 31 December 2022. Based on our inclusion criteria, 15 studies were selected for review. We found incomplete recording of data on the intensity and timing of physical activity. There was also wide variation in the terminology used to describe physical abilities. The study results suggested that aquatic interventions brought about improvements in endurance and strength; however, conflicting data were found with respect to balance and body mass index, and there were few data on biomarkers related to stress and brain health. Further research with more accurate training load data and a more common fitness terminology is needed. Lastly, traditional swimming should probably be considered as an aquatic intervention.
Intraocular Pressure Changes Following Three “Head below the Heart” Postures in Yoga Practitioners – A Prospective Observational Study

Context: Intraocular pressure (IOP) increases during “sirasasana” and may be a risk factor for the progression of glaucoma. Other “head below heart” asanas may also cause increase in IOP. Aims: To determine the change in IOP following three “head below the heart” postures-”meruasana”, “viparithakarni,” and “sarvangasana”. Settings and Design: Prospective observational study conducted in a tertiary care hospital over 3 weeks. Materials and Methods: Willing, regular yoga practitioners recruited by purposive sampling performed “meruasana”, “viparithakarni,” and “sarvangasana” in random order according to a 3 × 3 periods cross over study design after baseline measurement of IOP, blood pressure (BP), and pulse rate. Each asana was held for 30 s. Within 15–30 s of completion of asana, IOP, BP, and pulse rate were recorded. There was an interval of 30 min between the asanas. Statistical Analysis Used: Normality of data was tested using the Kolmogorov–Smirnov test. Repeated measures of ANOVA with Tukey-Kramer multiple comparisons was used to compare changes in IOP, BP, pulse rate following asana. P ≤ 0.05 was accepted as statistically significant. Results: There were 33 participants with a mean age of 29.6 ± 10.5 years (95% confidence interval [CI]: 26.02, 33.18). The mean baseline IOP was 15.5 ± 3.4 mm Hg (95% CI: 14.34, 16.66) in the right eye and 16.7 ± 3.4 mm Hg (95% CI: 15.54, 17.86) in the left eye. IOP showed a significant reduction following each of the three asanas (P < 0.0001). However, neither pulse rate (P = 0.53) nor BP (P = 0.27) showed any change following the asanas. Conclusions: “Meruasana,” “viparithakarni,” and “sarvangasana” when held for 30 s by healthy yoga practitioners resulted in post-asana drop in IOP with no significant change in pulse rate or BP.
Organ Doses for Foetuses, Babies, Children and Adults from Environmental Gamma Rays

Organ doses for babies, children and adults and doses to foetuses from environmental gamma rays were calculated using Monte Carlo codes. Firstly, gamma ray fields in the air-over-ground geometry were simulated, neglecting the disturbance of the radiation field by the human body. The exposure modes considered were semi-infinite homogeneous volume sources in the air, infinite plane sources at a depth of 0.5 g.cm −2 in the ground and homogeneous volume sources of a natural radionuclides in the ground. The results of the simulation of the gamma ray transport in the air-over-ground geometry were used as sources irradiating the anthropomorphic phantoms : an 8 week old baby, a seven year old child and two «reference» adult phantoms of a male and a female. the doses to foetuses were estimated from the dose to the uterus of the adult female. Dose conversion factors normalised to source intensity and air kerma were calculated for monoenergetic sources (15 keV to 10 MeV) and natural and artificial radionuclides
Ultrathin Strut Biodegradable Polymer-Coated Sirolimus-Eluting Coronary Stents: Patient-Level Pooled Analysis From Two Indian Registries

Background Despite significant evolution in stent technology, female gender, and patients with diabetes mellitus, multivessel disease, total occlusions, long lesions, and small vessels represent the “Achilles' heel” of contemporary percutaneous coronary intervention (PCI). We performed a pooled analysis of high-risk subgroup on patient-level data from the T-Flex registry (1,203 patients) and a real-world Indian registry (1,269 patients), with the aim of assessing one-year safety and clinical performance of ultrathin strut biodegradable polymer-coated Supra family of sirolimus-eluting stents (SES) (Sahajanand Medical Technologies Limited, Surat, India) in the real-world, all-comer population. Method We pooled the following high-risk subgroups data from two all-comer registries: female gender (n=678), diabetes mellitus (n=852), multivessel disease (n=406), total occlusions (n=420), long lesions (≥28 mm) (n=1241), and small vessels (≤2.5 mm) (n=726). Both the registries included patients with coronary artery disease who underwent implantation of at least one SES belonging to the Supra family of stents from May 2016 until March 2018, irrespective of lesion complexity and comorbidities. The primary endpoint was the incidence of target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction, and clinically indicated target lesion revascularization by percutaneous or surgical methods up to one year. The safety endpoint was stent thrombosis. Results According to prespecified high-risk subgroups, one-year rates of TLF and overall stent thrombosis, respectively, were as follows: female gender (4.9% and 0.6%), diabetes mellitus (6.9% and 1.0%), multivessel disease (6.4% and 0.8%), total occlusions (5.2% and 0.5%), long lesions (≥28 mm) (6.6% and 0.8%), and small vessels (≤2.5 mm) (6.1% and 1.3%). Conclusion This present pooled analysis demonstrated the one-year safety and clinical performance of ultrathin strut biodegradable polymer-coated Supra family of SES in a real-world, all-comer population, with considerably low rates of TLF and stent thrombosis.
Classification Trees for Heterogeneous Moment-Based Models

A basic problem in applied settings is that different parameters may apply to the same model in different populations. We address this problem by proposing a method using moment trees; leveraging the basic intuition of a classification tree, our method partitions the covariate space into disjoint subsets and fits a set of moments within each subspace. We prove the consistency of this estimator and show standard rates of convergence apply post-model selection. Monte Carlo evidence demonstrates the excellent small sample performance and faster-than-parametric convergence rates of the model selection step in two common empirical contexts. Finally, we showcase the usefulness of our approach by estimating heterogeneous treatment effects in a regression discontinuity design in a development setting.
