Engineered molecular diagnostic strategies for hepatocellular carcinoma: Integrating flexible photonic barcodes, liquid biopsies, and AI‐enhanced sensing platforms

FlexMat, EarlyView.
Abstract Early diagnosis of hepatocellular carcinoma (HCC) remains challenging because conventional serum biomarkers, especially alpha‐fetoprotein (AFP), show limited sensitivity for early‐stage disease. Recent progress in engineered molecular diagnostics provides new opportunities to improve HCC detection through integrated material, molecular, and ...

On the Error Statistics of Turbo Decoding for Hybrid Concatenated Codes Design

Journal of Communications Software and Systems, 2019
In this paper we propose a model for the generation of error patterns at the output of a turbo decoder. One of the advantages of this model is that it can be used to generate the error sequence with little effort.

Image Quality of 1.5 T MRI Using Dual‐Type Deep Learning Reconstruction for Pancreatic Cystic Lesions: An Exploratory Comparison With Conventional 3 T MRI Without Deep Learning Reconstruction

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dual‐type deep learning reconstruction (DLR) may improve the pancreatic MRI image quality; however, the effects of different DLR strengths at 1.5 T compared with the conventional 1.5 T and 3 T MRI without DLR remain unclear. Purpose To evaluate the image quality of 1.5 T MRI reconstructed with different DLR strengths for pancreatic ...

Space-Time Codes and Concatenated Channel Codes for Wireless Communications

, 2002
Following a brief historical perspective on channel coding, an introduction to space–time block codes is given. The various space–time codes considered are then concatenated with a range of channel codecs, such as convolutional and block-based turbo ...

Performance of Turbo-Codes with Some Proposed Interleaver Schemes

Al-Khawarizmi Engineering Journal, 2006
This paper describes a number of new interleaving strategies based on the golden section. The new interleavers are called golden relative prime interleavers, golden interleavers, and dithered golden interleavers. The latter two approaches involve sorting

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

Impact of Dapagliflozin on MRI‐Derived Epicardial Adipose Tissue: Secondary Imaging Analysis of a Randomized Trial

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Epicardial adipose tissue (EAT) is a metabolically active fat depot associated with cardiovascular risk and represents a modifiable imaging biomarker. Studies have shown that sodium–glucose cotransporter‐2 (SGLT2) inhibitors reduce EAT thickness in patients with type 2 diabetes mellitus (T2DM). However, it is unclear whether this is

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 ...
