This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

Optimized Distributed Generalized Reed-Solomon Coding with Space-Time Block Coded Spatial Modulation
We present a well-known generalized Reed–Solomon (GRS) code incorporated with space-time block coded spatial modulation (STBC-SM) for wireless networks, which is capable of enjoying coded cooperation between the source and the relay.

We study the performance of Reed-Solomon (RS) codes for the \em exact repair problem \em in distributed storage. Our main result is that, in some parameter regimes, Reed-Solomon codes are optimal regenerating codes, among MDS codes with linear repair ...

Performance Analysis of the LDPC‐Coded Hybrid LQAM‐MPPM for UWOC Systems
The effectiveness of LDPC codes in improving the performance of hybrid modulations is discussed, with coded 128‐QAM‐(12, 2) MPPM offering ~6.5 and 5.8 dB code gains at a BER of in strong and moderate turbulence, respectively. These results demonstrate the promise of hybrid modulation with LDPC as a robust and efficient modulation scheme for UWOC ...

Masculinities in Conservation Science, Policy and Practice: A Qualitative Systematic Review
ABSTRACT Gender equality is a key target for conservation but is often treated as a women's issue with limited attention to the roles of men and masculinities in perpetuating unequal gender relations. This paper provides a qualitative systematic review of academic literature on “masculinities”—actions, norms, and values associated with men—in the ...

ABSTRACT The present research investigates how changes in the extent to which decision‐makers rely on concrete or abstract thinking (i.e., construal level) influence responses to ethical scenarios as well as the relationship between those responses and actual, recalled, unethical behavior.

Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...
