Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

open access: yesExperimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Optimization study of low lateral force in eccentric ball-piston pumps

open access: yesAdvances in Mechanical Engineering
Eccentric ball piston pump is a high power density hydraulic component. In this paper, a low lateral force design method for an eccentric ball-piston pump is proposed to reduce the lateral force between the ball and the cylinder by slightly inclination ...

Measuring Dry Deposition of Sea Spray Aerosol and Height of Aerosol Plume Using a Controlled Wave Pool

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Deposition of sea spray aerosols facilitates atmospheric corrosion of materials, requiring maintenance and replacement over time. However, the dimensions of sea spray aerosol plumes produced from breaking waves have not been well‐characterized, limiting useful prediction of particle transport downwind and atmospheric corrosion. Therefore, this

Piston-assisted charge pumping

open access: yes, 2015
We examine charge transport through a system of three sites connected in series in the situation when an oscillating charged piston modulates the energy of the middle site. We show that with an appropriate set of parameters, charge can be transferred against an applied voltage.
