The complex genome and adaptive evolution of polyploid Chinese pepper (Zanthoxylum armatum and Zanthoxylum bungeanum)

open access: yesPlant Biotechnology Journal, Volume 21, Issue 1, Page 78-96, January 2023., 2023
Summary Zanthoxylum armatum and Zanthoxylum bungeanum, known as ‘Chinese pepper’, are distinguished by their extraordinary complex genomes, phenotypic innovation of adaptive evolution and species‐special metabolites. Here, we report reference‐grade genomes of Z. armatum and Z. bungeanum.

Full-Diversity Space-Time Error Correcting Codes with Low-Complexity Receivers

open access: yesEURASIP Journal on Wireless Communications and Networking, 2011
We propose an explicit construction of full-diversity space-time block codes, under the constraint of an error correction capability. Furthermore, these codes are constructed in order to be suitable for a serial concatenation with an outer linear ...

Impact of glacial cycles and ocean currents on radiation events in the Japanese turban snail Lunella coreensis

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

Interleaver Design for Turbo Codes [PDF]

open access: yesIEEE 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

open access: yesMacromolecular 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 ...

VHDL Implementation of different Turbo Encoder using Log-MAP Decoder [PDF]

open access: yesJournal of Telecommunications, Volume 2, Issue 1, p49-53, April 2010, 2010
Turbo code is a great achievement in the field of communication system. It can be created by connecting a turbo encoder and a decoder serially. A Turbo encoder is build with parallel concatenation of two simple convolutional codes. By varying the number of memory element (encoder configuration), code rate (1/2 or 1/3), block size of data and iteration,

Iterative H.264 Source and Channel Decoding Using Sphere Packing Modulation Aided Layered Steered Space-Time Codes

open access: yes, 2010
The conventional two-stage turbo-detection schemes generally suffer from a Bit Error Rate (BER) floor. In this paper we circumvent this deficiency by proposing a three-stage turbo detected Sphere Packing (SP) modulation aided Layered Steered Space-Time ...
