Identity‐Enabled CDMA LiDAR for Massively Parallel Ranging with a Single‐Element Receiver
Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.A novel LiDAR system integrates CDMA modulation with a single‐element detector to achieve massive channel parallel 3D imaging. By using a user identification code and a correlation‐based feedback loop, it overcomes signal collisions and the near‐far problem.

Interference-Free Broadband Single- and Multi-Carrier DS-CDMA
, 2005 The choice of the direct sequence spreading code in DS-CDMA predetermines the properties of the system. This contribution demonstrates that the family of codes exhibiting an interference-free window (IFW) outperforms classic spreading codes, provided ...

Canadian water‐related fatalities: Demographic, situational, and environmental risk factors
Journal of Forensic Sciences, Volume 70, Issue 6, Page 2403-2419, November 2025.Abstract Unintentional water‐related deaths are an ongoing global problem, despite being named by the United Nations as one of the leading preventable causes of death. To address the need for enhanced analysis of drowning risk factors, including demographic and situational conditions that may influence death outcomes, this research involved a three ...
