Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Lead Impacts on the Moist Static Energy Budget of the Low‐Level Arctic Atmosphere in Large‐Eddy Simulations Based on MOSAiC Data

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract High‐resolution large‐eddy simulations (LES) are used to examine the impact of Arctic sea‐ice leads on the wintertime lower atmosphere. Leads expose the cold atmosphere to the relatively warm ocean, and are thus critical to the Arctic energy budget.

An adaptive reclosing strategy for UHV AC transmission lines based on phase difference of single-end induced voltage

open access: yesInternational Journal of Electrical Power & Energy Systems
In ultra-high voltage (UHV) AC transmission systems, single-phase to ground faults account for more than 80 % of all faults. If reclosing is performed blindly under permanent fault conditions after a single-phase to ground fault, the system may suffer ...

A Time-Limited Adaptive Reclosing Method in Active Distribution Networks Considering Anti-Islanding Protection

open access: yesProcesses
In active distribution networks (DNs), distributed energy resources (DERs) must be disconnected from the grid prior to automatic reclosing actions. Many scholars have proposed non-voltage checking reclosing methods, but a significant challenge arises ...

ATGL From iWAT and BAT Is Crucial for Cardiac Remodeling and Metabolism After Myocardial Ischemia/Reperfusion

open access: yesComprehensive Physiology, Volume 16, Issue 1, February 2026.
Cardiac I/R activates adipose tissue. iatATGL‐KO increases adipocyte size and reduces lipogenesis in WAT, induces whitening and inflammation in BAT, and reduces circulating NEFA and adiponectin levels. As a consequence, cardiac function is reduced, scar formation enhanced, and remote myocardium shows elevated mechanical stress and oxygen consumption ...

Adaptive Single-Phase Reclosing in Transmission Lines

open access: yes, 2015
This research work is mainly concerned about dealing with temporary short circuit faults in power system transmission lines. In fact, there are two types of electrical faults in power systems, namely temporary and permanent. When a fault is permanent, the only way to clear it is to de-energize the transmission line by opening the associated circuit ...

Permanent Fault Identification Scheme for Distribution Feeders Using Detection‐Based Reclosing

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel permanent fault identification scheme based on detection‐based reclosing to mitigate the risks of blind three‐phase reclosing and overcome the sensitivity limitations of existing methods. ABSTRACT To mitigate secondary damage caused by reclosing a distribution line with a permanent fault, a highly sensitive fault property ...
