Implementation of a Fully-Parallel Turbo Decoder on a General-Purpose Graphics Processing Unit
IEEE Access, 2016 Turbo codes comprising a parallel concatenation of upper and lower convolutional codes are widely employed in the state-of-the-art wireless communication standards, since they facilitate transmission throughputs that closely approach the channel capacity.

Systemic bio‐inequity links poverty to biodiversity and induces a conservation paradox
People and Nature, EarlyView.Abstract Biodiversity is declining globally while inequity is growing, and poverty rates are not improving. Global sustainable development and conservation initiatives aim to address biodiversity loss and poverty simultaneously. Through text analysis of global biodiversity policies, we identified a consistent narrative that countries with high ...

Repeat-punctured superorthogonal convolutional turbo codes on AWGN and flat Rayleigh fading channels
South African Journal of Science, 2010 Repeat-punctured turbo codes, an extension of the conventional turbo-coding scheme, has shown a significant increase in bit-error rate performance at moderate to high signal-to-noise ratios for short frame lengths.

Muscle fatigue in patients with severe long COVID: A 2‐year follow‐up study
PM&R, EarlyView.Abstract Background Fatigue is recognized as one of the most persistent and debilitating symptoms of long COVID, affecting both functionality and quality of life. However, its long‐term effects, especially beyond the first year after infection, remain poorly understood.

Relay Switching Aided Turbo Coded Hybrid-ARQ for Correlated Fading Channel
, 2011 Hybrid-Automatic-Repeat-reQuest (HARQ) has become an indispensable technique in reliable communications systems. However, its performance is inevitably affected by the channel’s fading correlation. In this paper, we proposed a novel relay-switching aided

Pest Management Science, EarlyView.Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was
