A Generalization of a Classical Geometric Extremum Problem

Kenderov, Petar · Mushkarov, Oleg · Nikolov, Nikolai

Let \partial \,\mathcal{C} ∂ C be the boundary of a compact convex body \mathcal{C} C in \mathbb{R}^n,\, n\geq 2 R n , n ≥ 2 , and O O be an interior point of \mathcal C C . Every straight line l l containing O O cuts from \mathcal{C} C a segment [AB] [ A B ] with end-points on \partial \,\mathcal{C} ∂ C . It is shown...

A simplified and reproducible protocol for percutaneous lumbar intrathecal injection in rats

Raul Andres-Santamaria · Roan Hofstede · Maarten van de Wal · Annemieke Aartsma-Rus · y 2 más

Intrathecal injection is widely used in preclinical research to deliver compounds directly into the cerebrospinal fluid, bypassing the blood-brain barrier. However, current percutaneous lumbar puncture protocols vary considerably in equipment and procedural detail, limiting reproducibility across laboratories.We presen...

CXR-LT 2026 challenge: Multi-center long-tailed and zero shot chest X-ray classification

Hexin Dong · Yi Lin · Pengyu Zhou · Fengnian Zhao · y 24 más

Chest X-ray (CXR) interpretation is hindered by the long-tailed distribution of pathologies and the open-world nature of clinical environments. Existing benchmarks often rely on closed-set classes from a single institution, failing to capture the prevalence of rare diseases or the appearance of novel findings. To addre...

Generalized rank via minimal subposet

Thomas Brüstle · Justin Desrochers · Samuel Leblanc

Let $\mathcal{C}$ be a small, connected category with finite hom-sets. We show that if the embedding of a connected subcategory $\mathcal{J}$ is both initial and final, then the restriction of any $\mathcal{C}$-module along $\mathcal{J}$ preserves the generalized rank-or equivalently, the multiplicity of the ``entire"...

Identification of location and speciation of CeO2 micro and nanoparticles in radish and lettuce.

Avellan, Astrid · Henner, Pascale · Nfanda, Cheryl · Rose, Jerome · y 1 más

After nuclear accident, non-soluble radioactive particles serve as an additional source for human exposure to radioactivity, when transferred to agricultural crops. The foliar transfer mechanisms of such source into plants are poorly assessed by risk assessment tools which includes retention, incorporation and transloc...

Checking that equations on terms define a finite set of equivalence classes

Yohan Boichut · Thomas Genet

Given a set of equations on terms, we are interested in checking if the set of equivalence classes defined by these equations is finite or not. This theoretical problem finds applications in program verification, where finiteness of the set of equivalence classes ensures termination of the verification. We first show t...

On the rank of Jacobian varieties of the curves ys = axr + b

Sajad Salami

We study the family of algebraic curves of genus $\geq 1$ defined by the affine equations $y^s=ax^r+b$ over a number field $k$, where $r \geq 2$ and $s\geq 2$ are fixed integers. Assuming the strong version of Lang's conjecture on varieties of general type, we prove that the Mordell-Weil rank of the Jacobian varieties...

X-RAY REFLECTIVITY STUDY OF GRAPHENE OXIDE ASSEMBLY AT THE AIR-LIUQID INTERFACE

Andrei CHUMAKOV · Dmitrii PETUKHOV · Ilia SADILOV · Oleg KONOVALOV

The current proposal focuses on characterizing the behavior of pristine and modified graphene oxide (GO) nanoflakes at the air-liquid interface. A thin GO layer can be effectively utilized in applications such as transparent conductors, sensors, et al. Langmuir-Blodgett (LB) is a widely used technique for thin film dep...

Evaluating healthcare professionals’ perceptions of medicine risk communications: A survey with Quantitative and Qualitative Analyses

Anna V. Chatzi

Background: Effective medicine risk communication is a cornerstone of patient safety. Although safety information is routinely disseminated to healthcare professionals (HCPs), limited evidence exists on how these communications are perceived and acted upon in clinical practice. Objective: To assess how national medicin...
