Grey‐Body Factors and Absorption Cross‐Sections of Scalar and Dirac Fields in the Vicinity of Dilaton‐De Sitter Black Hole

open access: yesFortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Complete Ricci solitons via estimates on the soliton potential

open access: yes, 2019
In this paper a growth estimate on the soliton potential is shown for a large class of cohomogeneity one manifolds. This is used to construct continuous families of complete steady and expanding Ricci solitons in the set-ups of L\"u-Page-Pope and Dancer ...

Trends on Strategies for Mitigation of Antibiotic Residues in Milk and Dairy Products Based on Scientometric Analysis and Systematic Review

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT The presence of antibiotic residues (ARs) in milk poses a significant challenge to public health and the dairy industry. This study presents the research trends on strategies to mitigate ARs in milk and dairy products, combining scientometric and systematic review approaches.

Beyond the Hodge theorem: Curl and asymmetric pseudodifferential projections

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We develop a new approach to the study of spectral asymmetry. Working with the operator curl:=∗d$\operatorname{curl}:={*}\mathrm{d}$ on a connected oriented closed Riemannian 3‐manifold, we construct, by means of microlocal analysis, the asymmetry operator — a scalar pseudodifferential operator of order −3$-3$.

H-functional and Matsushima type decomposition theorem

open access: yes, 2019
The H-functional characterizes K\"ahler-Ricci solitons as its critical points, and also plays an important role of the existence problem for K\"ahler-Einstein metrics. In this paper we prove the Hessian formula for the H-functional at its critical points,

Specific effects on the reproductive function including fertility relevant for cumulative risk assessment of pesticide residues

open access: yesEFSA Journal, Volume 23, Issue 12, December 2025.
Abstract According to the ‘EFSA‐SANTE Action Plan on Cumulative Risk Assessment for pesticides residues’, EFSA, with the support of a working group, undertook the identification of specific effects on male and female reproductive function, including fertility, that are considered relevant for grouping pesticide residues and for assessing ...

Investigation of Mechanical and Thermal Properties of Modified Silica Aerogels/Epoxy/Aramid Composites

open access: yesPolymer Composites, Volume 46, Issue 16, Page 15313-15330, 10 November 2025.
Production process of amine‐modified silica aerogel reinforced aramid/epoxy composite (EAFS). ABSTRACT Due to its high pore size and low density, amine‐modified silica aerogel (XSA) is an excellent candidate for the secondary reinforcement material of polymer matrix composites.

Gray’s decomposition on doubly warped product manifolds and applications

open access: yes, 2019
A. Gray presented an interesting $O\left( n\right) $ invariant decomposition of the covariant derivative of the Ricci tensor. Manifolds whose Ricci tensor satisfies the defining property of each orthogonal class are called Einstein-like manifolds. In the

Multiscale Cell–Cell Interactive Spatial Transcriptomics Analysis

open access: yesAdvanced Science, Volume 12, Issue 44, November 27, 2025.
In this study, we present the MultiScale Cell‐Cell Interactive Spatial Transcriptomics Analysis method, which unites the strengths of spatially resolved deep learning techniques with a topological representation of multi‐scale cell‐cell similarity relations.
