A state metrics compressed decoding technique for energy-efficient turbo decoder

EURASIP Journal on Wireless Communications and Networking, 2018
In the energy resource-constrained wireless applications, turbo codes are frequently employed to guarantee reliable data communication. To both reduce the power dissipation of the turbo decoder and the probability of data frame retransmission in the ...

An Inline‐Integrable Image Restoration Model With ROI Fine‐Tuning and Slice‐to‐Volume Reconstruction for Accelerated Whole‐Brain Vessel Wall Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a vessel wall imaging (VWI)‐dedicated image restoration model enabling high‐resolution whole‐brain VWI in under 6 min. Methods A transformer‐based 2.5D model was trained in a supervised manner to enhance the image quality of CAIPIRINHA 2 × 2‐accelerated VWI acquisitions to a level comparable to that of GRAPPA twofold ...

Low-Complexity Multiple-Component Turbo Decoding Aided Hybrid ARQ

, 2011
Previous research has focused on improving the throughput of Hybrid Automatic Repeat reQuest (HARQ) schemes. However, since turbo codes have been introduced into HARQ schemes, their complexity has increased owing to the iterative Bahl, Cocke, Jelinek and

LLM‐based prior elicitation for Bayesian graphical modeling

British Journal of Mathematical and Statistical Psychology, EarlyView.
ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

Analysis of iteration control for turbo decoders in turbo synchronization applications [PDF]

Advances in Radio Science, 2009
Wireless data transmission results in frequency and phase offsets of the signal in the receiver. In addition, the received symbols are corrupted by noise.

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 ...

Evaluation of Low Density Parity Check Codes Over Various Channel Types [PDF]

Engineering and Technology Journal, 2011
Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it

Rapid Translation of the Early Coding Region Promotes Premature Transcription Termination, Reducing Protein Expression in Escherichia coli

Molecular Microbiology, EarlyView.
A run of consecutive fast‐translated codons (right) within the first 30 codons of lacZ (top) causes loss of the downstream transcript at positions coinciding with previously mapped intragenic Rho‐dependent termination sites (middle), and a corresponding loss of β‐galactosidase activity (bottom).

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]

, 2013
Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

TurboID‐based proteomic profiling reveals proxitome of the IRT1 metal transporter and new insight into IRT1 endocytosis

New Phytologist, EarlyView.
Identification of new regulators of Arabidopsis IRT1 endocytosis and metal transport using TurboID. TurboID proximity labeling of the Arabidopsis IRT1 root metal transporter identified new IRT1‐interacting proteins upon different metal regimes. Among validated candidates, the endosome‐localized NHX5 Na+ (K+)/H+ antiporter and the plasma membrane ...
