The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Block Turbo Code and its Application to OFDM for Wireless Local Area Network [PDF]

open access: yes, 2009
To overcome multipath fading and Inter symbol Interference (ISI), in convolutional single carrier systems equalizers are used. But it increases the system complexity.

A Turbo Coding System for High Speed Communications [PDF]

open access: yesarXiv, 2006
Conventional turbo codes (CTCs) usually employ a block-oriented interleaving so that each block is separately encoded and decoded. As interleaving and de-interleaving are performed within a block, the message-passing process associated with an iterative decoder is limited to proceed within the corresponding range. This paper presents a new turbo coding

Space-Time Codes Concatenated with Turbo Codes over Fading Channels [PDF]

open access: yes, 2004
The uses of space-time code (STC) and iterative processing have enabled robust communications over fading channels at previously unachievable signal-to-noise ratios.

Disease Aggravation With Age in an Experimental Model of Multiple Sclerosis: Role of Immunosenescence

open access: yesAging Cell, EarlyView.
Age‐related differences in EAE outcomes stem from combined peripheral and CNS factors. Key peripheral adaptive immunity changes include altered naïve/memory T cell ratios, Th1 skewing, increased suppressive Tregs, CD4+ T cell exhaustion, enhanced B cell antigen presentation, and reduced NK cell cytotoxicity.

Autoencoder-Based Error Correction Coding for One-Bit Quantization [PDF]

open access: yesarXiv, 2019
This paper proposes a novel deep learning-based error correction coding scheme for AWGN channels under the constraint of one-bit quantization in the receivers. Specifically, it is first shown that the optimum error correction code that minimizes the probability of bit error can be obtained by perfectly training a special autoencoder, in which ...

Circular RNA Telomerase Reverses Endothelial Senescence in Progeria

open access: yesAging Cell, EarlyView.
TERT circRNA outperforms linear TERT mRNA in reversing the hallmarks of senescence. TERT circRNA more efficiently restores endothelial function and shows superior capability in enhancing mitochondrial function. ABSTRACT Telomeres shorten with each cell division, acting as a chronometer of cell age. The enzyme telomerase, primarily active in stem cells,

Iterative decoding of Generalized Parallel Concatenated Block codes using cyclic permutations [PDF]

open access: yesIJCSI International Journal of Computer Science Issues, Vol. 9, Issue 5, No 1, September 2012 (ISSN (Online): 1694-0814), 2012
Iterative decoding techniques have gain popularity due to their performance and their application in most communications systems. In this paper, we present a new application of our iterative decoder on the GPCB (Generalized Parallel Concatenated Block codes) which uses cyclic permutations. We introduce a new variant of the component decoder.
