Polar codes with a stepped boundary

, 2017
We consider explicit polar constructions of blocklength $n\rightarrow\infty$ for the two extreme cases of code rates $R\rightarrow1$ and $R\rightarrow0.$ For code rates $R\rightarrow1,$ we design codes with complexity order of $n\log n$ in code ...

R code

, 2021
This zip file contains all of the R scripts used in the manuscript analysis, labeled in order they should be run by the number within the parentheses. If there is no number in parentheses at the end of the script name then the script contains functions and is sourced from within other R scripts.

Systematic Block Markov Superposition Transmission of Repetition Codes

, 2016
In this paper, we propose systematic block Markov superposition transmission of repetition~(BMST-R) codes, which can support a wide range of code rates but maintain essentially the same encoding/decoding hardware structure.

Explicit Representation and Enumeration of Repeated-Root (δ + αu²)-Constacyclic Codes Over F₂^m[u]/‹u^2λ›

IEEE Access, 2020
Let F2(m) be a finite field of 2m elements, λ and k be integers satisfying λ, k ≥ 2 and denote R = F2(m)[u]/(u2λ). Let δ, α ∈ F2(m)×.

Constant 2-Labellings And An Application To (R, A, B)-Covering Codes

Discussiones Mathematicae Graph Theory, 2017
We introduce the concept of constant 2-labelling of a vertex-weighted graph and show how it can be used to obtain perfect weighted coverings. Roughly speaking, a constant 2-labelling of a vertex-weighted graph is a black and white colouring of its vertex

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

FpRS-Additive Cyclic Codes are Asymptotically Good

IEEE Access
In coding theory, the rate and the relative minimum distance are two important invariants to assess a family of codes’ asymptotic characteristics.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Bounds on Covering Radius of Some Codes Over F₂ + uF₂ + vF₂ + uvF₂

IEEE Access, 2021
Let $R=\mathbb {F}_{2}+u\mathbb {F}_{2}+v\mathbb {F}_{2}+uv\mathbb {F}_{2}$ be a finite non-chain ring, where $u^{2}=u$ , $v^{2}=v$ , $uv=vu$ . We give the lower and upper bounds on the covering radius of different types of repetition codes for ...
