Los debates en torno al ferrocarril en España anteriores a la creación de RENFE: el camino hacia el monopolio de Estado

open access: yesIberian Journal of the History of Economic Thought, 2016
Desde su nacimiento hasta la caída de la dictadura de Primo de Rivera, el ferrocarril se perfiló como una industria doblemente creadora de riqueza, estimulando por un lado la ya existente e impulsando el desarrollo económico por otro.

Tuning Pair and Higher‐Order Mutual Information Measures in Oscillator Systems with N$N$‐Dependent Frequencies

open access: yesAdvanced Theory and Simulations, Volume 8, Issue 1, January 2025.
Pair and higher‐order mutual information measures in many‐particle (N$N$) coupled quantum oscillators can be tuned by using ω=N−α$\omega =N^{-\alpha }$ one‐body potential intensities. Critical points appear in the measures as N$N$ is varied, when α$\alpha$ is a fractional value.

Dynamic Pedestrian Demand Estimation Using Data From Reidentification Sensors: A New Research Challenge

open access: yesJournal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Many cities are currently working on the development of mobility policies aimed at improving the accessibility of transport infrastructures and the intermodality in the citizen’s daily travel. Some of these policies should focus on obtaining a more sustainable modal split distribution in the access to and egress from multimodal transportation hubs. The

Cell Death Mechanisms Produced by Carbon‐Based Nanoparticles

open access: yesJournal of Nanotechnology, Volume 2025, Issue 1, 2025.
Using carbon‐based nanoparticles, such as diamond, graphite, fullerene, and nanotubes, has increased their research as possible strategies for drug delivery to control diseases, especially cancer. However, because these materials, when interacting with the living environment, release substances that are capable of inducing cell death by themselves, it ...

Perspectives for European Railway Services [PDF]

open access: yes, 2004
En aquesta tesina s'hi exposen les característiques generals de les xarxes ferroviàries d'Europa i les causes que han incapacitat al ferrocarril per absorvir part alguna de l'augment de tràfic europeu dels últims trenta anys.

La sombra alargada del patrón: Gamonalismo y hábitos hacendatarios en Chimborazo tras la reforma agraria

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 29, Issue 4, Page 352-363, December 2024.
Abstract This paper explores selective aspects of the historical processes of organization of the kichwa peasantry in the Andes of Ecuador. Based on the analysis of two representative cases of confrontation between peasants and landowners over access to land in the province of Chimborazo, it discusses the relevance of the concept of “gamonalismo” as ...

The Separability Problem in Molecular Quantum Systems: Information‐Theoretic Framework for Atoms in Molecules

open access: yesChemPhysChem, Volume 25, Issue 14, July 15, 2024.
We explore the mathematical underpinnings of partitioning a molecule into its constituent atoms through the Atoms‐in‐Molecules (AIM) approach, validating its applicability through concepts from Information Theory. We present information‐theoretic justifications for employing some of the most widely utilized AIM partitioning schemes in chemistry, such ...
