Two‐Way Relaying for Orbital Angular Momentum LOS Transmission
International Journal of Communication Systems, Volume 38, Issue 13, 10 September 2025.This paper investigates two‐way relaying (TWR) for orbital angular momentum (OAM)‐based line‐of‐sight (LOS) transmission. Low‐complexity near‐ML detectors are proposed for OAM mode division multiplexing and index modulation. Theoretical analysis and simulations confirm that TWR significantly improves bit error performance and spectral efficiency over ...

Racket sociality: investigating intimidation in North India
Journal of the Royal Anthropological Institute, Volume 31, Issue 3, Page 771-788, September 2025.This article is an ethnographic investigation into acts of intimidation and threats. Theoretically, it dialogues with ‘racket’ – a key analytical term in the sociology of domination, state‐making, and mafias. The anthropology of power, violence, and crime has paid scant attention to the morphology of threats and the ways interpersonal intimidation ...

Nanophotonics, Volume 14, Issue 17, Page 2909-2922, August 2025.Abstract The terahertz (THz) frequency band has abundant spectrum resources, which is suitable for constructing communication systems with ultra‐high data rates and extremely low latency. Multiple input multiple output (MIMO) devices are crucial for realizing THz communication, and the synchronous transmission and noncorrelation of different channels ...
