Are lepton flavor mixings in the democratic mass matrix stable against quantum corrections? [PDF]

open access: yes, 2000
We investigate whether the lepton flavor mixing angles in the so-called democratic type of mass matrix are stable against quantum corrections or not in the minimal supersymmetric standard model with dimension five operator which induces neutrino mass ...

Voltage Stability Assessment Based on Modified Line Voltage Stability Index in the Presence of Renewable Energy Integration and Credible Contingencies

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
A modified line voltage stability index (MLVSI) is proposed to address limitations in the existing indices. The MLVSI is evaluated against Lmn, MVSI, and NCPI under varying load levels, renewable energy penetration, and contingency scenarios. It considers line resistance, power flow direction, and high‐loading events to identify critical lines and ...

Transfer Hydrogenation: Advances in Manganese and Nickel Metal Catalysis

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Transfer hydrogenation (TH) of ketones, catalyzed by transition–metal complexes, produces alcohols, which are important building blocks in the pharmaceutical and fine chemical industries. For a long time, catalysts based on noble metals such as ruthenium, rhodium, and iridium have dominated the TH of ketones.

Growth and Developmental Processes Alternate During Larval Development of Atlantic Herring

open access: yesEvolution &Development, Volume 27, Issue 4, December 2025.
During their development, fish pass through a series of developmental processes advancing, for example, their physiological and locomotive abilities. Gene expression analysis combined with histological and morphological analysis of Atlantic herring in different larval life stages showed two major growth periods in larval herring development alternating

Edge Clique Cover of Claw-free Graphs

open access: yes, 2016
The smallest number of cliques, covering all edges of a graph $ G $, is called the (edge) clique cover number of $ G $ and is denoted by $ cc(G) $. It is an easy observation that for every line graph $ G $ with $ n $ vertices, $cc(G)\leq n $. G.

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

open access: yesAdvanced Functional Materials, Volume 35, Issue 47, November 19, 2025.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

Neutrinos in a spherical box

open access: yes, 2003
In the present paper we study some neutrino properties as they may appear in the low energy neutrinos emitted in triton decay with maximum neutrino energy of 18.6 keV.

UK best practice recommendations for children and young people <18 years with pre‐stage 3 type 1 diabetes, on behalf of the British Society for Paediatric Endocrinology and Diabetes (BSPED)

open access: yesDiabetic Medicine, Volume 42, Issue 11, November 2025.
Abstract Screening for childhood type 1 diabetes (T1D) is increasing worldwide. Historically, screening has been undertaken through research programmes, but increasingly in the UK, children and young people are also being tested in clinical care.
