Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
High Voltage, EarlyView.ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Radiation effects on optical frequency domain reflectometry fiber-based sensor [PDF]
Optics Letters, 2015 We investigate the radiation effects on germanosilicate optical fiber acting as the sensing element of optical frequency domain reflectometry devices. Thanks to a new setup permitting to control temperature during irradiation, we evaluate the changes induced by 10 keV x rays on their Rayleigh response up to 1 MGy in a temperature range from -40°C up to

Reengineering the Baldree Traffic Simulator for turfgrass wear and traffic research
Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.Abstract Historically, turfgrass researchers utilized the Baldree Traffic Simulator (BTS) to imitate foot traffic for the evaluation of athletic field wear tolerance and performance. Research was conducted to reengineer the BTS “feet” to improve adaptability and compatibility with other aerification units and determine biophysical effects on two native

Fabrication Method for the High-Accuracy Optical Fiber Delay Line with Specified Length
Photonics, 2023 We propose a novel scheme for fabricating high-accuracy optical fiber delay lines (OFDLs). The fabrication system integrates a self-designed optical fiber cutting device and a high-accuracy fiber length measurement module based on optical frequency ...

Global Change Biology Communications, Volume 1, Issue 2, June 2026.Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Small Methods, Volume 10, Issue 11, 8 June 2026.The performance of polymer blend semiconductors is governed by both the degree of phase separation and crystallization, but these two aspects have remained unresolved. We report methods for mapping amorphous‐amorphous as well as amorphous‐crystalline phase separation in polyfluorene‐based polymer blends using spatially resolved nanobeam electron total ...

Radio Science, Volume 61, Issue 6, June 2026.Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...
