Optimizing Dielectric Rod Antenna Performance with Spoof Surface Plasmon Polariton-Based Feeding Method.

This study investigates the use of spoof surface plasmon polaritons (SSPPs) as an effective feeding mechanism for antennas functioning within the extremely high-frequency (EHF) range. A novel method is proposed for feeding a dielectric rod antenna with SSPPs, featuring a simple design made from FR-4 material with a relative permittivity of 4.3.

Two-Dimensional Porphyrin-Based Covalent Organic Frameworks/g-CN Composites as High-Performance Supercapacitor.

Covalent organic frameworks (COFs) with high porosity and redox-active properties have been advanced as electrode materials for energy storage systems, although poor electron conductivity and inaccessibility of active pore sites hinder their performance as electrode material for supercapacitor application. Thus, incorporation of a COF with various conductive materials can be an effective strategy to improve their electrochemical performances for supercapacitors. Herein, we report the synthesis of POR-COF@g-CN composites by fabricating a porphyrin-based COF on g-CN via in situ solvothermal conditions.

Exome sequencing in Asian populations identifies low-frequency and rare coding variation influencing Parkinson's disease risk.

Parkinson's disease (PD) is an incurable, progressive and common movement disorder that is increasing in incidence globally because of population aging. We hypothesized that the landscape of rare, protein-altering variants could provide further insights into disease pathogenesis. Here we performed whole-exome sequencing followed by gene-based tests on 4,298 PD cases and 5,512 controls of Asian ancestry.

Optoelectronic performance prediction of HgCdTe homojunction photodetector in long wave infrared spectral region using traditional simulations and machine learning models.

This research explores the design of an infrared (IR) photodetector using mercury cadmium telluride (HgCdTe). It proposes two- and three-dimensional homojunction models based on p-HgCdTe/n-HgCdTe, focusing on applications in the long-wavelength infrared range. The photodetector's performance is analyzed using Silvaco ATLAS TCAD software and compared with analytical calculations based on drift-diffusion, tunneling, and Chu's approximation techniques.

Visible-Light-Promoted Iron(II)/Lewis Base Catalysis for the Alkylation of Morita-Baylis-Hillman Acetates Using Carboxylic Acids.

A novel photoinduced Fe(OTf)/2,4,6-collidine-catalyzed alkylation of Morita-Baylis-Hillman (MBH) acetates using carboxylic acids in a regio- and stereoselective manner is reported. This method demonstrates a broad scope, encompassing various carboxylic acids and MBH acetates, including drugs and bioactive molecules, to synthesize densely functionalized cinnamates and acrylates. The reactions are performed in the green solvent dimethyl carbonate under oxidant-free conditions.

Baseline susceptibility of an A1 quarantine pest - the South American tomato pinworm (Lepidoptera: Gelechiidae) to insecticides: past incidents and future probabilities in line to implementing successful pest management.

Tomato is a widely cultivated crop significant for its economic and nutritional benefits. The South American tomato pinworm, , originated in Peru South America and has invaded many nations, causing up to 100% yield loss in tomatoes. The pest was classified as a quarantine pest by the European Plant Protection Organization, before invading the Spain region.

Evaluation of virulence determinants and cell surface properties associated with biofilm formation in methicillin-resistant Staphylococcus aureus (MRSA) and extended spectrum beta-lactamase (ESBL) Escherichia coli from livestock and poultry origin.

Antibiotic resistance poses a persistent threat to modern medicine due to the emergence of novel antibiotic-resistant strains. Therefore, a timely understanding of antibiotic resistance and the virulence biology of pathogenic bacteria, particularly those of public health significance, is crucial for implementing effective mitigation strategies. This study aimed to investigate the virulence profiles of ten S.

Childhood maltreatment is linked to larger preferred interpersonal distances towards friends and strangers across the globe.

Childhood maltreatment (CM) is thought to be associated with altered responses to social stimuli and interpersonal signals. However, limited evidence exists that CM is linked to larger comfortable interpersonal distance (CID) - the physical distance humans prefer towards others during social interactions. However, no previous study has investigated this association in a comprehensive sample, yielding sufficient statistical power.

Minimizing risk while maximizing opportunity: The infectious disease organ offer process survey.

Background: The purpose of this study was to understand how transplant infectious disease (TID) physicians assess a potential donor with known or suspected infection and describe posttransplant management.

Methods: We designed a survey of 10 organ offer scenarios and asked questions pertaining to organ acceptability for transplantation and management posttransplant. The survey was distributed to TID clinicians via transplant society listservs and email.

Unveiling the limits of precision in iterative MINFLUX.

In single-molecule microscopy, a big question is how precisely we can estimate the location of a single molecule. Our research shows that by using iterative localisation microscopy and factoring in the prior information, we can boost precision and reduce the number of photons needed. Leveraging the Van Trees inequality aids in determining the optimal precision achievable.

Academic Productivity of Applicant and Program as Predictors of a Future Academic Career in Neurosurgery.

Background And Objectives: Academic productivity is viewed as a critical objective factor for a neurosurgery residency applicant. There has been a consistent rise in academic productivity over the last decade, but a lack of consistent data on the utility of this in helping neurosurgery residency programs identify which applicants will enter academic neurosurgery. This cross-sectional study evaluates the predictiveness of academic productivity before and during residency on career choice, both independent and dependent of training environment.

The effect of friction stir processing on mechanical, wear and corrosion characteristics of Cu-AlN-BN surface composite.

This research investigates the impact of hybrid particles dispersed onto the surface of a copper matrix using Friction Stir Processing (FSP) on its microstructural, mechanical, and corrosion behavior. The hybrid particles under study consist of equal fractions of Aluminium Nitride (AlN) and Boron Nitride (BN). Microstructural characterization confirms breakdown of grain size due to dynamic recrystallization and presence of particles, along with their effective bonding to copper matrix.

An artificial intelligence-based dental semantic search engine as a reliable tool for dental students and educators.

Purpose/objectives: This study proposes the utilization of a Natural Language Processing tool to create a semantic search engine for dental education while addressing the increasing concerns of accuracy, bias, and hallucination in outputs generated by AI tools. The paper focuses on developing and evaluating DentQA, a specialized question-answering tool that makes it easy for students to seek information to access information located in handouts or study material distributed by an institution.

Methods: DentQA is structured upon the GPT3.

Prevalence of Oral Manifestations in COVID-19-Diagnosed Patients at a Tertiary Care Hospital in Kerala.

Background: COVID-19, a pandemic since 2019, is still causing significant healthcare burden across the world. Although the disease primarily presents with respiratory symptoms, a multitude of signs and symptoms may be manifested elsewhere in the body.

Aim: This study was to estimate the prevalence of oral manifestations in COVID-19 diagnosed patients and thereby understand the effects of corona virus disease on oral health.

A randomised controlled trial comparing umbilical cord milking to delayed cord clamping at birth in preterm infants 28-36 weeks gestational age.

Unlabelled: Delayed cord clamping (DCC) is an established practice in perinatology with multiple benefits. However, in instances where the implementation of DCC is not viable, it needs alternatives, especially during caesarean deliveries. A non-inferiority randomized, non-blinded, trial was conducted at a tertiary care referral unit in South India among the preterm newborns (28-36 weeks) randomized to DCC as opposed to intact-umbilical cord milking (UCM).
