Meta‐Analysis: Prevalence of Non‐ Helicobacter pylori , Non‐ NSAID Peptic Ulcer Disease
BACKGROUND: Non-Helicobacter pylori (H. pylori), non-nonsteroidal anti-inflammatory drug (NSAID) peptic ulcer disease (PUD) is increasingly recognized as a distinct subgroup, but its proportion across clinical presentations remains unclear. AIM: We aimed to estimate this proporti...

Enhanced Room-TemperaturePhosphorescence from CarbonDots Embedded in a Robust SiO2 Matrix
Abstract Carbon dots (CDs) represent a rapidly advancing class of fluorescent nanomaterials. Due to the dominant nonradiative decay channels of the triplet excited state of CDs, these materials generally exhibit no observable phosphorescence (PH) or delayed fluorescence. Here, we...

Time-resolved imaging of antiferromagnetic skyrmion interactions
Abstract Quantifying particle interactions is central to understanding and controlling collective dynamics in particle-based devices such as those comprising skyrmion ensembles. Here we directly visualize, in real time, the nanosecond current-driven dynamics of an antiferromagnet...

Fabrication and performance evaluation of TiO2 nanoparticle modified cellulose/PBS biocomposites
Abstract In this study, jute fiber cellulose (JFC) was extracted from raw jute fibers using an alkaline (NaOH + H 2 O 2 ) chemical treatment. Titanium dioxide (TiO 2 ) nanoparticle-dispersed cellulosic biocomposite films (JFC-TiO 2 ) were subsequently fabricated and coated with b...

A genotype-first approach reveals the molecular basis of pyrin inflammasome activation
Mutations in the MEFV gene, which encodes pyrin, are associated with a spectrum of inflammatory conditions called pyrin-associated autoinflammatory diseases (PAADs). Of the 400 MEFV variants listed in the Infevers database, most are classified as variants of uncertain significanc...

An N-terminal CDC42 T43I variant reveals the mechanism of pyrin inflammasome activation
Heterozygous carboxyl-terminal variants in the RHO guanosine triphosphatase (GTPase) CDC42 are known to cause severe autoinflammatory syndromes. Here, we identified a heterozygous amino-terminal p.T43I (Thr 43 →Ile) CDC42 variant in patients with autoinflammation and uncovered a...

Detection of Weld Root Crack in Metal Plates with Convolutional Neural Network
The detection of weld root cracks in metal plates using nonlinear ultrasonics and a convolutional neural network (CNN) was investigated. Lamb waves with a fundamental frequency of 0.5 MHz were transmitted into a carbon steel plate specimen, and the waveforms were recorded using a...
