Interleaver Design for Turbo Codes [PDF]

IEEE J. Selected Areas Communication, 19 (2001), 831-837, 2002
The performance of a Turbo code with short block length depends critically on the interleaver design. There are two major criteria in the design of an interleaver: the distance spectrum of the code and the correlation between the information input data and the soft output of each decoder corresponding to its parity bits.

Targeting MDA‐MB‐231 Cancer Stem Cells With Temsirolimus in 3D Collagen/PGA/Na2SiO3‐Based Bone Model

Macromolecular Materials and Engineering, EarlyView.
The efficacy of the mTORC1 inhibitor temsirolimus is assessed on CD44+/CD24‐ CSCs from MDA‐MB‐231, using a 3D bone‐like model with a PLA scaffold. Osteogenic differentiation of BM‐MSCs and CSC invasion are induced. After applying IC50 = 5 µM for 6 hours, mTOR protein levels are evaluated, stemness, epthelial‐mesenchymal transition (EMT), and drug ...

A Perspective of Multi‐Reflecting TOF MS

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Joint k‐b space diffusion‐weighted image reconstruction and apparent diffusion coefficient fitting for diffusion‐weighted turbo‐spin‐echo imaging

Medical Physics, EarlyView.
Abstract Background Diffusion‐weighted (DW) turbo‐spin‐echo (TSE) imaging offers improved geometric fidelity compared to single‐shot echo‐planar‐imaging (EPI). However, it suffers from low signal‐to‐noise ratio (SNR) and prolonged acquisition times, thereby restricting its applications in diagnosis and MRI‐guided radiotherapy (MRgRT).

Performance Analysis of Deep Learning based on Recurrent Neural Networks for Channel Coding [PDF]

arXiv, 2018
Channel Coding has been one of the central disciplines driving the success stories of current generation LTE systems and beyond. In particular, turbo codes are mostly used for cellular and other applications where a reliable data transfer is required for latency-constrained communication in the presence of data-corrupting noise.

A Randomized Construction of Polar Subcodes

, 2017
A method for construction of polar subcodes is presented, which aims on minimization of the number of low-weight codewords in the obtained codes, as well as on improved performance under list or sequential decoding. Simulation results are provided, which

Rewiring of the seed metabolome during Tartary buckwheat domestication

Plant Biotechnology Journal, Volume 21, Issue 1, Page 150-164, January 2023., 2023
Summary Crop domestication usually leads to the narrowing genetic diversity. However, human selection mainly focuses on visible traits, such as yield and plant morphology, with most metabolic changes being invisible to the naked eye. Buckwheat accumulates abundant bioactive substances, making it a dual‐purpose crop with excellent nutritional and ...
