Identification of Novel CD52+ Fibroblasts in Nodular Prostatic Hyperplasia

The Prostate, EarlyView.
ABSTRACT Background Benign prostatic hyperplasia (BPH) and lower urinary tract symptoms are strongly associated with chronic prostate inflammation and stromal remodeling, yet the stromal cell programs that emerge during inflammatory, nodular remodeling remain incompletely defined. A Toxoplasma gondii infection model produces persistent inflammation and

Fractional p&q-Laplacian problems with potentials vanishing at infinity [PDF]

, 2020
In this paper we prove the existence of a positive and a negative ground state weak solution for the following class of fractional p&g-Laplacian problems [formula] where [formula]and [formula] are continuous, positive functions, allowed for vanishing ...

Propagation of internal gravity waves: Optimal vertical discretisation and grid design based on numerical error analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving discrete framework for the vertical discretisation of stratified ocean models is developed using internal gravity‐wave theory. A β$$ \beta $$‐indexed family of schemes is analysed through perturbation theory, revealing optimal parameter choices and grid designs that reduce truncation errors significantly.

The second eigenvalue of the fractional p-Laplacian [PDF]

Advances in Calculus of Variations, 2016
AbstractWe consider the eigenvalue problem for the fractional p-Laplacian in an open bounded, possibly disconnected set ${\Omega\subset\mathbb{R}^{n}}$, under homogeneous Dirichlet boundary conditions. After discussing some regularity issues for eigenfunctions, we show that the second eigenvalue ${\lambda_{2}(\Omega)}$ is well-defined, and we ...

A new scale‐selective measure of curvature for meteorological fields

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We introduce a novel diagnostic called curvature using radial variation (CURV) that quantifies the local cyclonic or anticyclonic curvature of mean‐sea‐level pressure or geopotential height gridded fields over selected scales. A depiction of how CURV values relate to differing cyclonic curvature is shown in the figure.

Evaluation of a stochastically perturbed parametrisations scheme for sea ice in sub‐seasonal forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Overconfident sea ice forecasts pose a challenge in subseasonal prediction. To test a potential way to address this issue and account for sea ice model uncertainty, this article investigates a stochastically perturbed parametrisations (SPP) scheme for sea ice in a prototype CY49R2 configuration of the coupled IFS‐NEMO4‐SI3 system. The results show that

Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

Remote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

Fractional Laplacian with Supercritical Killings

Communications in Mathematical Physics
In this paper, we study Feynman-Kac semigroups of symmetric $α$-stable processes with supercritical killing potentials belonging to a large class of functions containing functions of the form $b|x|^{-β}$, where $b>0$ and $β>α$. We obtain two-sided estimates on the densities $p(t, x, y)$ of these semigroups for all $t>0$, along with estimates ...

Rapid and Efficient Affinity Isolation of Engineered Extracellular Vesicles Encapsulating Functional Proteins via Internal Twin‐Strep Tetraspanin Tagging

Small, EarlyView.
Structure‐guided internal twin‐Strep tagging of the tetraspanins CD63 or CD9 enables rapid and efficient antibody‐free affinity isolation of engineered extracellular vesicles (EVs) using Strep technology while allowing luminal protein loading. The approach removes over 96% of contaminants, separates tagged EVs from coexisting viral particles, and ...
