Concave Grain Boundaries Stabilized by Boron Segregation for Efficient and Durable Oxygen Reduction

Geng, X.; Vega-Paredes, M.; Lu, X.; Chakraborty, P.; Li, Y.; Scheu, C.; Wang, Z.; Gault, B. (2024-09-17)

The oxygen reduction reaction (ORR) is a critical process that limits the efficiency of fuel cells and metal-air batteries due to its slow kinetics, even when catalyzed by platinum (Pt). To reduce Pt usage, enhancing both th...

Multi-task Online Learning for Probabilistic Load Forecasting

Zaballa, O.; Álvarez, V.; Mazuelas, S. (2024-11-01)

Load forecasting is essential for the efficient, reliable, and cost-effective management of power systems. Load forecasting performance can be improved by learning the similarities among multiple entities (e.g., regions, bui...

Nonlocal cooperative behaviour, psychological effects, and collective decision-making: an exemplification with predator-prey models

Saha, S.; Pal, S.; Melnik, R. (2024-01-01)

In bio-social models, cooperative behaviour has evolved as an adaptive strategy, playing multi-functional roles. One of such roles in populations is to increase the success of survival and reproduction of individuals and th...

Analysis of the impact of fear in the presence of additional food and prey refuge with nonlocal predator-prey models

Saha, S.; Pal, S.; Melnik, R. (2025-01-01)

There are many positive and negative factors present in the predator-prey interaction which affect the net growth of the species. Fear of predation is one such factor that creates psychological stress in a prey species, whi...
