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

open access: yesInternational 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

open access: yesJournal 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.

Earth-orbiting resonant-mass gravitational wave detectors

open access: yes, 1989
Earth-based gravitational wave detectors suffer from the need to support the large antenna masses against the earth's gravity without transmitting a significant amount of seismic noise.

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air

open access: yesLaser &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

open access: yesMacromolecular 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.

Simulation of Heterodyne Signal for Science Interferometers of Space-Borne Gravitational Wave Detector and Evaluation of Phase Measurement Noise

open access: yesPhotonics
Interferometric signals in space-borne Gravitational Wave Detectors are measured by digital phasemeters. The phasemeter processes signals generated by multiple interferometers, with its primary function being micro-radian level phase measurements.

Electromagnetic and Gravitational Waves on a de Sitter background

open access: yes, 2009
One of the longstanding problems of modern gravitational physics is the detection of gravitational waves, for which the standard theoretical analysis relies upon the split of the space-time metric g into background plus perturbations.

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

open access: yesMathematical 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.
