Turbo-detected unequal protection audio and speech transceivers using serially concatenated convolutional codes, trellis coded modulation and space-time trellis coding [PDF]

, 2005
The MPEG-4 TwinVQ audio codec and the AMR-WB speech codec are investigated in the context of a jointly optimised turbo transceiver capable of providing unequal error protection.

Turnip mosaic virus utilizes the lipid droplet biogenesis machinery to facilitate its propagation in plants

New Phytologist, EarlyView.
Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions, including membrane remodeling during abiotic stress.

Turbo Detection of Symbol-Based Non-Binary LDPC-Coded Space-time Signals using Sphere Packing Modulation [PDF]

, 2005
A recently proposed space-time signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design.

A root–soil association index reveals life‐history strategies of arbuscular mycorrhizal fungi

New Phytologist, EarlyView.
Phylogenetic tree of Glomeromycota, including all studied virtual taxa, based on the small subunit region. The bar plot in the external part of the phylogeny depicts the log‐transformed arbuscular mycorrhizal root–soil association index, with values > 0 indicating rhizophilic lifestyle, < 0 edaphophilic lifestyle, and close to 0 no preference.

Revisiting the calculation of effective free distance of turbo codes [PDF]

, 2008
The expression for the minimum Hamming weight of the output of a constituent convolutional encoder, when its input is a weight-2 sequence is revisited. The new expression particularly facilitates the calculation of the effective free distance of recently

Targeted Modulation of Eukaryotic Release Factor 1 (OseRF1) by an RNA Aptamer Enhances Drought Adaptation in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Drought stress severely restricts rice productivity, necessitating strategies to enhance stress resilience. Here, we identify translation termination as a tunable regulatory node for stress adaptation. Using 25 rounds of SELEX, we isolated RTAR, an RNA aptamer that binds the rice eukaryotic release factor 1 (OseRF1) with nanomolar affinity ...

Loss of DET1 in High Pigment 2 Tomato Prevents High Temperature Repression of Anthocyanin Biosynthesis in Fruit Through HY5 Stabilization

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming impacts several aspects of plant physiology, with important negative effects on crop yield and production of secondary metabolites, such as anthocyanins. The anthocyanin content of vegetables and fruits has attracted public interest in the last two decades due to its health benefits, leading to the development of novel ...

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, EarlyView.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Alleviation of photoaging‐associated MMP upregulation, prostanoid biosynthesis, and cell cycle arrest with titanium dioxide, zinc oxide, and inorganic‐only (ZnO + TiO2) sunscreens

Photochemistry and Photobiology, EarlyView.
Inorganic sunscreens containing the UV filters titanium dioxide (TiO2) and/or zinc oxide (ZnO) alleviated various biomarkers of photoaging in human dermal fibroblasts, at a gene and protein level. The study provides novel insights that observe the impact of inorganic photoprotection through the molecular biology of skin.
