Dynamic Rating of Overhead Transmission Lines over Complex Terrain Using a Large-Eddy Simulation Paradigm [PDF]

, 2017
Dynamic Line Rating (DLR) enables rating of power line conductors using real-time weather conditions. Conductors are typically operated based on a conservative static rating that assumes worst case weather conditions to avoid line sagging to unsafe ...

Hypoxic and Fe‐Responses are Regulated by the ERFVII Factors and the PCO Branch of the N‐Degron Pathway According to Iron Availability

Plant, Cell &Environment, EarlyView.
ABSTRACT In plants, iron homeostasis and oxygen metabolism are strictly related, indeed several Fe‐requiring enzymes catalyze reactions that also involve O2 as a reagent, product, entry or end point of the pathway. Oxygen sensing itself relies on the Fe‐dependent enzymes Plant cysteine oxidases.

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

Numerical Assessment of Thermal Effects in Bundled Overhead Conductors for Dynamic Line Rating

Applied Sciences
Dynamic Line Rating (DLR) is increasingly important for maximizing capacity of existing overhead transmission lines. Conventional thermal rating methods, such as IEEE 738 and model conductors as single, isothermal cylinders and offer limited guidance for

Spatially Resolved Current Density and Electrochemical Impedance Spectroscopy in PEM Fuel Cells

Fuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT The durability and efficiency of proton exchange membrane fuel cells (PEMFC) are crucial for their deployment in heavy‐duty applications. The membrane‐electrode assembly (MEA) of a PEMFC plays a central role and can be characterized using in situ methods like polarization curves, current density mapping, and electrochemical impedance ...

The Contribution of Time Domain Structures to Electron Loss During the 17 March 2013 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Ring current modeling has been a subject of active research in the last two decades. However, accurately modeling of this population of particles remains a challenge. Several recent studies have demonstrated that ring current models can overestimate the trapped electron flux in the 10–50 keV range by up to two orders of magnitude during ...

Modeling Ganymede's Surface Charging in Preparation for the JUICE Mission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The European Space Agency's (ESA) JUICE mission (JUpiter ICy moons Explorer) is en route to the Jovian system to characterize Ganymede's subsurface ocean. Determining the ocean's conductivity and depth requires precise measurements of its induced magnetic field at the position of JUICE.
