Quantitative susceptibility mapping in magnetically inhomogeneous tissues
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose Conventional quantitative susceptibility mapping (QSM) methods rely on simplified physical models that assume isotropic and homogeneous tissue properties, leading to artifacts and inaccuracies in biological tissues. This study aims to develop and evaluate DEEPOLE, a deep learning–based method that incorporates macroscopically ...

Cooperative Signaling with Soft Information Combining
Journal of Electrical and Computer Engineering, 2010 We propose a Decode-and-Forward (DF) scheme using distributed Turbo code (DTC) for a three-node (source, relay, and destination) wireless cooperative communication system. The relay decodes, then interleaves, and reencodes the decoded data.

Serially Concatenated Turbo Codes
2009 5th International Conference on Wireless Communications, Networking and Mobile Computing, 2009 The paper presents a new scheme of concatenated codes, referred to as Serially Concatenated Turbo (SCT) codes. The code is constructed as the serial combinations of two turbo codes, i.e. turbo Recursive Systematic Convolutional (RSC) codes and turbo Bose Ray Chaudhuri Hocquenghem (BCH) codes, linked by a pseudo-random interleaver.

Improving irregular turbo codes
Electronics Letters, 2011 The influence of the degree profile on the performance of an irregular turbo code (TC) is analysed using hierarchical EXtrinsic Information Transfer (EXIT) charts. Then, an irregular TC concatenated with a post-encoder of unity rate at its output is proposed to improve the distance properties.

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT ZraS is a metal sensor integral to ZraPSR, a two‐component signaling system found in enterobacters. It belongs to a family of bifunctional sensor histidine kinases (SHKs) and is speculated to sense zinc‐induced stress on the bacterial envelope.
