Measuring the Orbital Angular Momentum of Light Based on Optical Differentiation
Pubblicazione 2023-01-01TestoThe utilization of orbital angular momentum (OAM) in light for information encoding is a promising avenue, as it exhibits resilience against environmental disturbances. However, the direct detection of OAM poses a significant challenge due to beam distortion during transmission, which ultimately lim...

Effects of hesperidin and ascorbic acid combination on boar sperm quality during cryopreservation
Pubblicazione 2025-07-01TestoHesperidin or ascorbic acid is an effective antioxidant that can protect frozen-thawed sperm from oxidative damage. The aim of the present study was to investigate the cryoprotective effects of hesperidin (Hsd) and ascorbic acid (AsA) on boar sperm quality during cryopreservation. Sperm samples were...

Precise Measurement of Polarization Variation Using Weak Measurement With Double Pointers
Pubblicazione 2023-01-01TestoIn this paper, a weak measurement scheme with double pointers (mean value shift and intensity shift of the post-selected light) is presented to simultaneously measure the tiny polarization change (phase and amplitude) of light in a single experimental apparatus. Furthermore, rather than using charge...

Surface Plasmon Resonance (SPR) Sensor Based on Optimal Pre- and Post-Selection
Pubblicazione 2019-01-01TestoA surface plasmon resonance (SPR) refractive index sensing technique based on the optimal pre-and post-selection (PPS) is put forward. The intensity contrast ratio (ICR) is introduced to estimate the precision of this sensing technique. Compared with the traditional sensing techniques, our method sh...

Associations of lung function impairment and biological aging with mortality and cardiovascular disease incidence: findings from UK biobank participants
Pubblicazione 2025-07-01TestoBackgroundLung function impairment, including preserved ratio impaired spirometry (PRISm) and airflow limitation (AL), is associated with increased risks of mortality and cardiovascular disease; however, the underlying biological mechanisms remain poorly understood. This study aimed to investigate t...
