Differences in associations between attention‐deficit hyperactivity disorder symptoms and physical activity across childhood and adolescence and among males and females in a representative UK birth cohort

JCPP Advances, EarlyView.
Abstract Background Children and adolescents with attention‐deficit hyperactivity disorder (ADHD) exhibit higher physical activity (PA) levels than peers without ADHD. It remains unclear how this association evolves across developmental stages and differs between sexes.

Tracking Summer Greenland Blocking: The Upstream Pathway Shapes Historical Extremes and Future Change

International Journal of Climatology, EarlyView.
This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Sono‐Anatomy and Histology of the Deep Fasciae in the Upper Limb

Journal of Ultrasound in Medicine, EarlyView.
The deep fascia of the upper limb represents a pivotal anatomical structure essential for effective force transmission, dynamic compartmentalization and musculoskeletal stability. Its composition (rich in type I collagen fibers) enables both mechanical resilience and functional adaptability, crucial for the upper limb's complex movements.

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air

Laser &Photonics Reviews, EarlyView.
Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

Early Warning for Lensed Gravitational Wave Counterparts from Time Delays of Their Host Galaxies Observed in the Optical

The Astrophysical Journal
Gravitational lensing of gravitational waves can be leveraged to provide early-warning times of ${ \mathcal O }({\rm{hours}})$ to ${ \mathcal O }({\rm{days}})$ before the merger of binary neutron stars (BNSs) and neutron star black holes (NSBHs). This in

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.
