Alpha‐adrenergic mediated changes in blood pressure variability after hypoxia‐ischaemia in preterm fetal sheep

The Journal of Physiology, EarlyView.
Abstract figure legend Clinical detection of brain injury in preterm infantsremains a significant challenge. We investigated whether evolving brain injuryafter severe hypoxia‐ischaemia (HI) in chronically instrumented preterm fetalsheep is associated with dynamic changes in arterial blood pressure variability(BPV) and tested the hypothesis that post‐HI

Finding a mix of renewable energy for different stakeholders by applying multi‐criteria decision‐making techniques

International Transactions in Operational Research, Volume 33, Issue 4, Page 2499-2534, July 2026.
Abstract This paper presents a two‐stage model for planning a renewable energy portfolio by balancing economic, social and environmental sustainability goals. The first stage addresses a multi‐objective problem where conflictive impacts generated by the energy portfolios should be optimised according to the corresponding economic, social or ...

Personalized Differential Privacy for Ridge Regression Under Output Perturbation

Naval Research Logistics (NRL), Volume 73, Issue 4, Page 525-537, June 2026.
ABSTRACT The increased application of machine learning (ML) in sensitive domains requires protecting the training data through privacy frameworks, such as differential privacy (DP). Traditional DP enforces a uniform privacy level ε$$ \varepsilon $$, which bounds the maximum privacy loss that each data point in the dataset is allowed to incur.
