An electromagnetic Gaussian Schell-model source that produces a random beam may be characterized by eight independent quantities. We show how far-zone measurements of the Stokes parameters, together with the Hanbury Brown-Twiss coefficient, allow one to determine all the source parameters. This method provides, to the best of our knowledge, a new tool to identify distant sources.

Objective: This study aims to investigate the monthly variation patterns of bioelectrical impedance (BEI) along 24 meridian pathways in healthy individuals.
Methods: A cohort of 684 healthy middle-aged participants from North China was enrolled between July 1, 2017, and September 5, 2020. BEI measurements were consistently recorded along the 24 meridian pathways over the study period.
We derive the Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts of random electromagnetic beams with arbitrary state and degree of polarization and spatial coherence. Further, we demonstrate the general formalism by calculating analytic expressions for the GH and IF shifts of an electromagnetic Gaussian Schell-model (EGSM) beam and show that the GH shifts may exist irrespective of the degree and state of polarization of the beam, while the IF shifts vanish when the beam is either s or p polarized or completely unpolarized. In addition, the spatial coherence width of the EGSM beam is found to influence only the angular GH and IF shifts.

Cancer and its diverse variations pose one of the most significant threats to human health and well-being. One of the most aggressive forms is blood cancer, originating from bone marrow cells and disrupting the production of normal blood cells. The incidence of blood cancer is steadily increasing, driven by both genetic and environmental factors.

The pH of venison is affected by deer capture methods, which affects its water-holding capacity (WHC) during heating. Therefore, cooking or processing venison requires careful consideration of WHC at different pH levels. While this requires nondestructively measuring the pH of venison during distribution, there are no established methods to nondestructively distinguish between normal- and high-pH meats.

This paper presents research on the security performance of a multi-user interference-based mixed RF/FSO system based on SWIPT untrusted relay. In this work, the RF and FSO channels experience Nakagami-m fading distribution and Málaga (M) turbulence, respectively. Multiple users transmit messages to the destination with the help of multiple cooperating relays, one of which may become an untrusted relay as an insider attacker.
