Thermally Stable Organic Synaptic Transistors Using a High‐Tg Polymer Electret

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
A high–glass‐transition‐temperature cyclic olefin copolymer (COC) electret enables thermally stable organic synaptic transistors for neuromorphic operation in harsh environments. UV–ozone treatment increases the trap density in COC, providing robust multilevel conductance and key synaptic functions (excitatory postsynaptic current/ inhibitory ...

Nucleotide Metabolism in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks

Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Improving 3D-Turbo Code's BER Performance with a BICM System over Rayleigh Fading Channel [PDF]

Radioengineering, 2016
Classical Turbo code suffers from high error floor due to its small Minimum Hamming Distance (MHD). Newly-proposed 3D-Turbo code can effectively increase the MHD and achieve a lower error floor by adding a rate-1 post encoder.
