Bibliometric analysis of Alzheimer's and dementia research in Latin America

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Dementia is increasing rapidly in Latin America and the Caribbean (LAC), but research output remains limited. Tracking publication trends, themes, and collaborations is key to guiding regional research and policy. METHODS Bibliometric analysis was conducted on dementia‐related publications from 21 LAC countries (1990 to 2024 ...

Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Decay in chloride content of ground water due to excessive production of a well field near León, Mexico

open access: yesGeofísica Internacional, 2005
El campo de pozos de La Muralla, cerca de León, Guanajuato, México, extrae agua por medio de 19 pozos profundos. Los 629 análisis del cloruro del agua extraída entre 1994 y 1999 muestran una tendencia global decreciente de - 1.1 mg/L por año, estimada ...

Baryon chiral perturbation theory transferred to hole-doped antiferromagnets on the honeycomb lattice

open access: yes, 2012
A systematic low-energy effective field theory for hole-doped antiferromagnets on the honeycomb lattice is constructed. The formalism is then used to investigate spiral phases in the staggered magnetization as well as the formation of two-hole bound ...

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

A Characterisation of Extreme‐Heat Occurrence and Its Trends in Mexico Based on a High Resolution Dataset

open access: yesInternational Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
As Mexico faces rising temperatures and increasing events of extreme heat, improvements in the analysis and characterisation of these phenomena are necessary, as they offer new insights into the spatial variability of such trends and their underlying causes.

Kirk Broders Assistant Professor of Biological Sciences, COLSA, travels to Mexico [PDF]

open access: yes, 2014
I was able to make my first trip to central Mexico in August 2014, in part due to assistance from the CIE Development Grant, in order to conduct research and develop a collaborative network with agricultural scientists in Mexico. The main purpose of the

Spectroscopic variability of two Oe stars [PDF]

open access: yes, 2015
The Oe stars HD45314 and HD60848 have recently been found to exhibit very different X-ray properties: whilst HD60848 has an X-ray spectrum and emission level typical of most OB stars, HD45314 features a much harder and brighter X-ray emission, making it ...
