Pulse pressure is associated with cognitive performance in Japanese non-demented population: a cross-sectional study

open access: yesBMC Neurology, 2022
Background Growing evidence suggests that vascular risk factors, especially hypertension, relate not only to cardiovascular disease but also to cognitive impairment. However, the impact of pulse pressure on cognitive function remains controversial.

Elevated pulse pressure and its associations with demographic and clinical parameters in a clinically representative sample of outpatients with psychotic disorders

open access: yesBJPsych Open, 2022
Elevated pulse pressure is associated with metabolic and neurocognitive diseases. Preliminary small-scale studies among patients with psychotic disorders have indicated that these patients had an increased pulse pressure compared with controls.

PHz scale spectral broadening and few-cycle compression of Yb:KGW laser pulses in a pressurized, gas-filled hollow-core fiber [PDF]

open access: yes, 2022
We demonstrate efficient generation of coherent super-octave pulses via a single-stage spectral broadening of a Yb:KGW laser in a single, pressurized, Ne-filled, hollow-core fiber capillary. Emerging pulses spectrally spanning over more than $\sim$1 PHz (250 nm- 1600 nm) at a dynamic range of $\sim$60 dB, and an excellent beam quality open the door to ...
