Article Synopsis
- - This study used genotyping-by-sequencing to identify single nucleotide polymorphisms (SNPs) in recombinant inbred lines of chickpeas to understand drought tolerance, identifying 35,502 SNPs and filtering down to 3,237 high-quality ones linked to drought traits.
- - Researchers found nine key quantitative trait loci (QTLs) for traits like seed weight and yield under drought conditions, with significant proportions of variance explained, highlighting a notable QTL on linkage group 7 that greatly impacts membrane stability.
- - The study identified 369 potential candidate genes within the QTL regions, and through further analysis, narrowed it down to 99 genes involved in significant signaling pathways related to drought stress, establishing a
Hardware Implementation of a Fixed-Point Decoder for Low-Density Lattice Codes.
J Signal Process Syst
January 2022
This paper describes a field-programmable gate array (FPGA) implementation of a fixed-point low-density lattice code (LDLC) decoder where the Gaussian mixture messages that are exchanged during the iterative decoding process are approximated to a single Gaussian. A detailed quantization study is first performed to find the minimum number of bits required for the fixed-point decoder to attain a frame error rate (FER) performance similar to floating-point. Then efficient numerical methods are devised to approximate the required non-linear functions.
