Community-informed and codesigned research to understand the impacts of railways on wildlife. [PDF]

Conserv Biol
Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Hydrodesulfurization of Dibenzothiophene: A Machine Learning Approach. [PDF]

ChemistryOpen
This work analyzes the hydrodesulfurization (HDS) process by compiling data on catalysts derived from MoS2, including their composition, structure, and experimental conditions. Using supervised machine learning methods such as regularized regression and random forest, the study estimates the conversion of DBT and the reaction selectivity.

Evaluating Quinolines: Molecular Dynamics Approach to Assess Their Potential as Acetylcholinesterase Inhibitors for Alzheimer's Disease. [PDF]

Chemphyschem
A number of dihydroxyl‐quinolines obtained from CADMA‐chem protocol are tested as inhibitors of acetylcholinesterase enzyme, an important target for therapies, in the framework of molecular dynamics simulations. Energetic and structural analysis of the trajectories allow the identification of dq1368 (3,4 dihydroxyl‐quinoline‐8‐carboxylic acid methane ...

Low‐cost technologies in a rich ecological context: Hotel California open‐air site at Sierra de Atapuerca, Burgos, Spain

Journal of Quaternary Science, Volume 38, Issue 5, Page 658-684, July 2023., 2023
ABSTRACT Hotel California is part of a network of open‐air Neanderthal sites located in the Sierra de Atapuerca (Burgos, Spain). In this study, we examine the technology of the lithic assemblages recovered from this site's archaeological levels 3 to 7, which are characterised by the use of local raw materials, non‐hierarchical centripetal exploitation ...
