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

Tongxin 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

EURASIP 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 ...

sGC stimulator BAY 41‐8543 improves survival and ventricular function in a rat model of doxorubicin‐induced cardiomyopathy with nephrotic syndrome

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Anthracyclines such as doxorubicin (DOXO) remain a cornerstone of cancer therapy but are associated with a high risk of cardiotoxicity and subsequent heart failure (HF). Impairment of NO/soluble guanylyl cyclase (sGC)/cGMP pathway has been reported in anthracycline‐induced cardiomyopathy.

Space-Time Turbo Coded Modulation: Design and Applications

EURASIP 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.

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

Ecological 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.

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

The 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.

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B

The FEBS Journal, EarlyView.
The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...

Structural and mutational analysis of Methanosarcina mazei prenylated FMN synthase reveals the basis of its unique prenyl donor substrate specificity

The FEBS Journal, EarlyView.
Some prenylated flavin mononucleotide (prFMN) synthases exceptionally prefer dimethylallyl phosphate (DMAP) over dimethylallyl diphosphate (DMAPP), which is a common prenyl donor substrate for many prenyltransferases. Structural and mutagenic analyses of Methanosarcina mazei prFMN synthase, which prefers DMAP but can also accept DMAPP, elucidated its ...

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Developing and Evaluating the Use of ChatGPT as a Screening Tool for Nurses Conducting Structured Literature Reviews: Proof of Concept Study Results

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aim To examine the feasibility of using a large language model (LLM) as a screening tool during structured literature reviews to facilitate evidence‐based practice. Design A proof‐of‐concept study. Methods This paper outlines an innovative method of abstract screening using ChatGPT and computer coding for large scale, effective and efficient ...
