Codebook Design for PD-SCMA NOMA Systems
The hybrid power domain sparse code non-orthogonal multiple access (PD-SCMA) scheme multiplexes multiple users on a single resource element (RE) both in power and code domains, thus achieving a superior spectral efficiency.

White matter microstructure and longitudinal relaxation time anisotropy in human brain at 3 and 7 T
White matter (WM) with high structural anisotropy T1 shows angular dependency on B0. At 3T, a T1 peak at 54° and flat baseline across 0° and 90° are observed in WM [Panel A, T1 as a function of fibre‐to‐filed angle (q)]. At 7T, the T1 peak is centred at 40°.

18O‐enrichment of liver glycogen, triglyceride glycerol, and blood glucose of mice given 18O‐water during overnight feeding was quantified by 13C NMR and MS. Glycogen 18O‐enrichment of oxygens 3, 5, and 6 from isotope‐shifted 13C signals informed indirect pathway contributions from different sources.

In this study, a novel composite based on calcium phosphate ceramic and the plasma‐treated hydrogel is developed. With such a combination it is possible to supplement the excellent bone regenerative properties of calcium phosphates bone grafts with an anticancer agent, that is, the plasma‐treated hydrogel. While being selective toward OS cells in vitro,

New High Performance Deterministic Interleavers for Turbo Codes
Turbo codes offer extraordinary performance, especially at low signal to noise ratios, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing

Analysis and Design of Tuned Turbo Codes [PDF]
It has been widely observed that there exists a fundamental trade-off between the minimum (Hamming) distance properties and the iterative decoding convergence behavior of turbo-like codes.

Reprograming of proteasomal degradation by branched chain amino acid metabolism
Using genetics and multi‐omics analyses in Caenorhabditis elegans, we identified adaptive regulation of the ubiquitin‐proteasome system (UPS) in response to defective branched chain amino acid (BCAA) metabolism. Worms with impaired BCAA metabolism show slower turnover of a GFP‐based proteasome substrate, which is suppressed by loss‐of‐function of the ...

A VHDL Code for Offset Pulse Position Modulation Working with Reed Solomon System by Using ModelSim
Error correction codes, often known as ECC, play a significant part in the process of detecting and correcting data mistakes that occur through communication channels that are unreliable or noisy.

DIFFERENT FPGA PRODUCTS BASED IMPLEMENTATION OF LTE TURBO CODE
In the long-term evolution (LTE) physical layer, using turbo code is considered as the paramount one in error-correcting coding. This paper presents an implementation of LTE turbo decoding using the Log- Maximum a posteriori (MAP) algorithm with reduced ...
