Combined effects of normobaric hypoxia and cold on respiratory system responses to high‐intensity exercise

open access: yesExperimental Physiology, EarlyView.
Abstract Cold temperatures (<−15°C) increase exercise‐induced bronchoconstriction (EIB), while hypoxic‐induced hyperventilation exacerbates respiratory muscle fatigue for a given exercising task. This study aimed to determine the individual and combined effects of cold and normobaric hypoxia on the respiratory system responses to high‐intensity ...

Bioavailable testosterone and androgen receptor activation, but not total testosterone, are associated with muscle mass and strength in females

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐seven pre‐menopausal, untrained females performed a 12‐week resistance training programme to explore the association between androgen concentrations, androgen receptor signalling and skeletal muscle size and strength. Total testosterone was not associated with muscle mass or strength, nor with resistance training‐induced ...

Parkinson's disease‐linked Kir4.2 mutation R28C leads to loss of ion channel function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Pathogenic impact of the PD‐linked Kir4.2R28C mutation on Kir4.2 channel proteostasis and function. The Kir4.2R28C mutation, identified in a familial Parkinson's disease (PD) pedigree, leads to a near‐complete loss of potassium channel function and exerts a significant dominant‐negative effect.

Twenty‐Five Years of Probabilistic Fault Displacement Hazard Assessment

open access: yesReviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Fault displacement hazard poses significant risks to critical infrastructure such as buildings, roads, and pipelines. While some structures can tolerate a certain degree of surface displacement, others, such as buildings, are far more vulnerable. Probabilistic Fault Displacement Hazard Assessment (PFDHA) quantifies the probability of exceeding

Fluid mechanics experiments in oscillatory flow. Volume 2: Tabulated data [PDF]

open access: yes
Results of a fluid mechanics measurement program in oscillating flow within a circular duct are presented. The program began with a survey of transition behavior over a range of oscillation frequency and magnitude and continued with a detailed study at a
