We report an experimental observation of the collision between a linear wave propagating in the anomalous dispersion region of an optical fiber and a dark soliton located in the normal dispersion region. This interaction results in the emission of a new frequency component whose wavelength can be predicted using phase-matching arguments. The measured efficiency of this process shows a strong dependency with the soliton grayness and the linear wave wavelength, and is in a good agreement with theory and numerical simulations.

Objective: The oxidative balance score (OBS) has emerged as a novel marker for assessing oxidative stress status. This study aimed to investigate the association of OBS with systolic blood pressure (SBP), diastolic blood pressure (DBP), all-cause, and cardiovascular disease mortality in hypertensive patients.
Methods: We conducted an analysis of data from 7602 hypertensive patients from the National Health and Nutrition Examination Survey (NHANES) 2005-2018.

Introduction: To examine the longitudinal association between estimated pulse wave velocity (ePWV) and cognitive phenotypes in a rural Chinese older population.
Methods: This population-based study included 1857 dementia-free participants (age ≥60 years) who were examined in 2014 and followed in 2018. ePWV was calculated using age and mean blood pressure (MBP).

Red blood cell distribution width (RDW) has recently been recognized as a novel biomarker associated with various cardiovascular conditions. This study aims to investigate the relationship between RDW and carotid-femoral pulse wave velocity (cfPWV) in a southern Chinese population. A total of 4916 patients were initially enrolled from the First Affiliated Hospital of Fujian Medical University between January 2016 and December 2022.

Aims: Hepcidin regulates plasma and tissue iron levels. We studied the association of hepcidin levels with the risk of incident heart failure (HF) and cardiac dysfunction in older adults.
Methods: We included adults from the ongoing, longitudinal Atherosclerosis Risk in Communities (ARIC) study who were free from prevalent anemia and HF at Visit 5 (2011-2013) and had available hepcidin and covariate data.

Vortex beams are currently drawing a great deal of interest, from fundamental research to several promising applications. While their generation in bulky optical devices limits their use in integrated complex systems, metasurfaces have recently proven successful in creating optical vortices, especially in the linear regime. In the nonlinear domain, of strategic importance for the future of classical and quantum information, to date orbital angular momentum has only been created in qualitative ways, without discussing discrepancies between design and experimental results.
