Calibration of an econometric model for the analysis of the frequency of traffic accidents with pedestrians

open access: yesRevista Ingenio, 2017
In the city of Ocaña Norte de Santander, in recent years there has been a high accident rate where pedestrians are involved, both injury and death. One of the main causes of accidents where pedestrians are involved is mainly the lack of pedestrian spaces

Electroweak monopoles and their stability

open access: yesNuclear Physics B, 2022
We apply a generalized field ansatz to describe the spherically symmetric sector of classical solutions in the electroweak theory. This sector contains Abelian magnetic monopoles labeled by their magnetic charge n=±1,±2,…, the non-Abelian monopole for n=±

Electroweak multi-monopoles

open access: yesNuclear Physics B, 2023
We construct the multi-charge generalizations for the electroweak magnetic monopole solution of Cho and Maison within a wide range of values of the magnetic charge. We use the same ansatz for the axially symmetric fields as the one previously employed to

Boundary singular problems for quasilinear equations involving mixed reaction-diffusion

open access: yesСовременная математика: Фундаментальные направления, 2022
We study the existence of solutions to the problem \[\label{eng_A1} \begin{array}{rl} -\Delta u+u^p-M|\nabla u|^q=0 \text{in }\;\Omega,\\ u=\mu \text{on }\;\partial\Omega \end{array}\] in a bounded domain \(\Omega\), where \(p1\), \(1q2 ...

Note méthodologique - Évaluer la fonctionnalité de la Trame bleue pour les poissons

open access: yesSciences, Eaux & Territoires, 2018
Pour que la trame bleue soit fonctionnelle, il est important de diagnostiquer l'effet de la fragmentation des cours d'eau sur les poissons pour en restaurer de manière efficace la continuité.

Le trascrizioni dei sogni dei sopravvissuti di Auschwitz: analisi linguistica e tematica secondo un modello XML-TEI

open access: yesUmanistica Digitale, 2020
In 1973, a psychiatric team from the Medical Academy of Krakow sent a questionnaire to Auschwitz survivors. The 147 people who answered, provided the material behind this research project: daily lives, anxieties and hopes through the stories of their ...

Affine twisted length function

open access: yesComptes Rendus. Mathématique, 2021
Let $W_a$ be an affine Weyl group. In 1987 Jian Yi Shi gave a characterization of the elements $w \in W_a$ in terms of $\Phi ^+$-tuples $(k(w,\alpha ))_{\alpha \,\in \,\Phi ^+}$ called the Shi vectors.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
