Sprint‐interval training with post‐exercise blood flow restriction increases mitochondrial content and respiration

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The mechanisms underpinning improved maximal oxygen uptake following sprint interval training (SIT) with post‐exercise blood flow restriction (BFR), compared to SIT alone, remain unclear. This study examined the effects of 6 week SIT with (BFR; n = 12) or without (CON; n = 8) post‐exercise BFR on V̇O2peak${{\dot{V}}_{{{{\mathrm{O}

Key Drivers for Offshore Wind Deployment in the Western United States

open access: yesWind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT The western coast of the United States has abundant natural resources, including wind, sun, and water. Despite strong ocean winds, offshore wind energy (OSW) in the Western United States is in the early stages of technology development due largely to the deep water off the coast, which requires floating platforms rather than fixed‐bottom ...

Numerical Investigations on the Transient Performance of a Centrifugal Pump

open access: yes
Centrifugal pumps are an integral part of plants used in process industries. The flow structure within a centrifugal pump is very complex due to the interaction between the rotating impeller and the geometric features around it.

Application of Electrical Resistance Probes for Corrosion Monitoring and Cathodic Protection Assessment of Offshore Structures

open access: yesMaterials and Corrosion, Volume 77, Issue 7, Page 1145-1158, July 2026.
A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.
