Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

open access: yesEpilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...

Two‐Block Paths in Oriented Graphs of Large Semidegree

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We study the existence of oriented paths with two blocks in oriented graphs under semidegree conditions. A block of an oriented path is a maximal directed subpath. Given positive integers k $k$ and ℓ $\ell $ with k / 2 ≤ ℓ < k $k/2\le \ell \lt k$, we establish a semidegree function that guarantees the containment of every oriented path with ...

Climate Change Projections for Mexico in the 21st Century

open access: yesInternational Journal of Climatology, EarlyView.
Projected national temperature by the end of the century under four SSP scenarios. Under the low‐emission pathway (SSP1‐2.6), warming increases more gradually, whereas under the high‐emission scenario (SSP5‐8.5), temperatures exceed 5°C by 2100. These results strengthen the scientific basis for climate adaptation planning and long‐term decision‐making ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.
