An Exact Method for Reliable Shortest Path Problems With Correlation

open access: yesNetworks, Volume 87, Issue 4, Page 372-389, June 2026.
ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for

Strategic Behaviour, Resource Valuation and Competition in Electricity Markets [PDF]

open access: yes
By means of a suitable Bayesian game we study spot electricity markets from a structural point of view. We address the problem of individual and aggregate eficciency and we show how to value water from market observables.

Contrasting Osmotic Stress Responses and Provenance Effects on Seed Germination and Seedling Performance in Two Andean Species

open access: yesPlant-Environment Interactions, Volume 7, Issue 3, June 2026.
Oreocallis grandiflora was highly drought‐sensitive, whereas Salvia corrugata recovered and showed adaptive traits. Provenance effects were strong in O. grandiflora but weak in S. corrugata. These results reveal species‐ and provenance‐dependent responses to water limitation, highlighting the importance of selecting suitable species and seed sources ...

Ambient heat and early childhood development: a cross‐national analysis

open access: yesJournal of Child Psychology and Psychiatry, Volume 67, Issue 6, Page 929-940, June 2026.
Background Increasing evidence suggests that climate change, along with its cascading impacts on ecosystems, societies, and communities, has significant effects on both physical and mental health. However, less is known about how exposure to excessive heat early in life may influence the development of foundational skills that shape lifelong ...

GPS velocities and the construction of the Eastern Cordillera of the Colombian Andes

open access: yesGeophysical Research Letters, 2016
AbstractGPS velocities across the northeast trending Eastern Cordillera of Colombia show oblique convergence at 8.8 ± 1.7 mm/yr, consisting of 8.0 ± 1.7 mm/yr of right‐lateral strike‐slip shear along the mountain range and 3.7 ± 0.3 mm/yr of northwest southeast shortening. Faster convergence occurs only at the northeast end of the Cordillera, where its
