An alternative interpretation of the phenomenon of edge diffraction is proposed according to a new separation of the Fresnel function. The subfields are investigated in the problem of diffraction of a plane wave by a perfectly conducting half-plane, and the results are compared numerically with other interpretations.

Background: Accurate mortality estimates help quantify and memorialise the impact of war. We used multiple data sources to estimate deaths due to traumatic injury in the Gaza Strip between Oct 7, 2023, and June 30, 2024.
Methods: We used a three-list capture-recapture analysis using data from Palestinian Ministry of Health (MoH) hospital lists, an MoH online survey, and social media obituaries.

VTRNA2-1 is a polymorphically imprinted locus. The proportion of individuals with a maternally imprinted VTRNA2-1 locus is consistently approximately 75% in populations of European origin, with the remaining circa 25% having a non-methylated VTRNA2-1 locus. Recently, VTRNA2-1 hypermethylation at birth was suggested to be a precursor of paediatric acute lymphoblastic leukaemia with biomarker potential.

Post-dural puncture headache (PDPH) is a debilitating complication of neuraxial anesthesia, particularly prevalent in obstetric patients, usually characterized by a postural headache. PDPH is hypothesized to result from cerebrospinal fluid leakage through a dural puncture, triggering symptoms like neck stiffness and subjective hearing changes. While conservative measures are common for treatment, more refractory cases may require invasive interventions such as an epidural blood patch (EBP).

Physical literacy (PL) is increasingly being implemented as a means for holistic development for children and youth. Despite this, children experiencing disabilities and their families continue to face barriers that impede participation in physical activities and subsequent PL development. To empower families to actively engage in their PL development, this study sought to provide an accessible, home- and play-based, parent-facilitated intervention, namely, PLayTubs.

Background: Gastrointestinal (GI) diseases pose significant challenges for healthcare systems, largely due to the complexities involved in their detection and treatment. Despite the advancements in deep neural networks, their high computational demands hinder their practical use in clinical environments.
Objective: This study aims to address the computational inefficiencies of deep neural networks by proposing a lightweight model that integrates model compression techniques, ConvLSTM layers, and ConvNext Blocks, all optimized through Knowledge Distillation (KD).
