Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

open access: yesEcological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.

Sensitivity analysis of the channel estimation deviation to the MAP decoding algorithm

open access: yesTongxin xuebao, 2006
As a necessary input parameter for MAP decoding algorithm,SNR was normally obtained from the channel estimation unit.Corresponding research indicated that SNR estimation deviation degraded significantly the performance of Turbo decoding.MAP decoding ...

An Efficient SF-ISF Approach for the Slepian-Wolf Source Coding Problem

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
A simple but powerful scheme exploiting the binning concept for asymmetric lossless distributed source coding is proposed. The novelty in the proposed scheme is the introduction of a syndrome former (SF) in the source encoder and an inverse syndrome ...

Look-up Table Based Deferred-Iteration Aided Low-Complexity Turbo Hybrid ARQ

open access: yes, 2011
Since the introduction of turbo code aided Hybrid Automatic Repeat reQuest (HARQ) schemes, their complexity reduction has drawn research attention. In our previous work, we proposed an Early Stopping (ES) strategy for a turbo HARQ scheme, which results ...

RNF13 is a previously undescribed interactor of iduronate 2‐sulfatase that modifies its glycosylation and maturation

open access: yesThe FEBS Journal, EarlyView.
Iduronate 2‐sulfatase (IDS; purple) is expressed as a precursor protein that goes through multiple steps of maturation, modification, and trafficking to become an active lysosomal enzyme that degrades glycosaminoglycans. Our study shows that the transmembrane ubiquitin ligases RNF13 (orange) and RNF167 (pink) heterodimerize, affecting IDS intracellular

Turbo-Detected Unequal Error Protection Irregular Convolutional Codes Designed for the Wideband Advanced Multirate Speech Codec

open access: yes, 2005
—since the different bits of multimedia information, such as speech and video, have different error sensitivity, efficient unequalprotection channel coding schemes have to be used to ensure that the perceptually more important bits benefit from more ...

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Space-Time Turbo Coded Modulation: Design and Applications

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A design method for recursive space-time trellis codes and parallel-concatenated space-time turbo coded modulation is proposed that can be applied to an arbitrary existing space-time trellis code.

Quantitative analysis of DNA‐GATA1 binding alterations linked to hematopoietic disorders

open access: yesThe FEBS Journal, EarlyView.
Native holdup allows the quantitative determination of affinities between full‐length transcription factors and DNA. Mutations in either the protein or the DNA can modulate binding strength, which can be precisely quantified using this approach. Applied to GATA1, it revealed mutations that alter DNA binding.
