Analysis of the distribution of HII regions in external galaxies. IV The new galaxy sample. Position and Inclination angles [PDF]

, 2002
We have compiled a new sample of galaxies with published catalogs of HII region coordinates. This sample, together with the former catalog of Garcia-Gomez and Athanassoula (1991) will form the basis for subsequent studies of the spiral structure in disc ...

Headwater drainage evolution in a foreland basin system using surfaces and topographic metrics (Zadorra River, Upper Ebro, Spain)

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Headwater drainage evolution in the Ebro foreland basin system from N Spain, including the Zadorra River drainage system and its relationships with the Arakil River. Abstract Foreland basins are elongate depressions that develop around the flanks of collisional mountain ranges.

The Association Between Metalinguistic Awareness and Chinese Word Reading: A Three‐Level Meta‐Analysis

Language Learning, Volume 75, Issue 4, Page 1222-1256, December 2025.
Abstract This study involved a three‐level meta‐analysis on the correlations between metalinguistic awareness (i.e., orthographic, phonological, and morphological awareness) and Chinese word reading. Based on 16,823 individuals from 81 studies, the results revealed moderate associations between all three metalinguistic skills and Chinese word reading ...

Duval Triangle-Based Dissolved Gas Analysis using GNU Octave for Transformer Fault Detection

Aviation Electronics, Information Technology, Telecommunications, Electricals, Controls
Transformers are vital components in electrical power systems. However, they are also susceptible to various types of failures, including thermal and electrical faults caused by the formation of electromotive force, which, if left unaddressed, may result

Inefficient star formation through turbulence, magnetic fields and feedback

, 2015
Star formation is inefficient. Only a few percent of the available gas in molecular clouds forms stars, leading to the observed low star formation rate (SFR). The same holds when averaged over many molecular clouds, such that the SFR of whole galaxies is

Overcoming Stability Hurdles of Transition Metal Phosphides for H2 Evolution: A Review

ChemSusChem, Volume 18, Issue 20, October 23, 2025.
Developing durable electrocatalysts for water splitting remains a major challenge. This review examines strategies to enhance the long‐term stability of earth‐abundant transition metal phosphides for hydrogen evolution. It covers advances in material design and modification across pH conditions and includes stability analyzes in practical electrolyzer ...

A Classical Version of the Non-Abelian Gauge Anomaly

, 2013
We show that a version of the covariant gauge anomaly for a 3+1 dimensional chiral fermion interacting with a non-Abelian gauge field can be obtained from the classical Hamiltonian flow of its probability distribution in phase space.

Maximizing the potential benefits of beaver restoration for fire resilience and water storage

Ecological Applications, Volume 35, Issue 7, October 2025.
Abstract Restoring populations of native keystone species can increase landscape resilience to global change when those species create or modify ecosystems. The North American beaver (Castor canadensis) is an ecosystem engineer that increases river water storage and residence time, increasing fire resilience at the landscape level.

An adaptive multi-fuzzy logic model for diagnosing transformer faults using dynamic weight optimization

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Dissolved gas analysis (DGA) is crucial for diagnosing early power transformer failures. Traditional DGA interpretation methods like Duval Triangle, IEC ratio, Roger ratio, Doernenburg ratio and Key Gas are inconsistent and vary in accuracy, especially ...

Recovery of Daily Water Levels in the Sacramento‐San Joaquin Delta, 1915–2023

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
Newly digitized records of daily maximum and minimum water levels have been recovered from 25 distinct locations across the Sacramento/San Joaquin Delta region, extending the period of record by several decades. Analysing longer records will improve understanding of the processes influencing water levels in this dynamic region. ABSTRACT This manuscript
