Quality of cause-of-death data in Brazil: Garbage codes among registered deaths in 2000 and 2015 [PDF]

Revista Brasileira de Epidemiologia, 2019
Introduction: reliability of mortality data is essential for health assessment and planning. In Brazil, a high proportion of deaths is attributed to causes that should not be considered as underlying causes of deaths, named garbage codes (GC).

More Constructions of 3-Weight Linear Codes

Journal of Mathematics, 2021
Linear codes with few weights have become an interesting research topic and important applications of cryptography and coding theory. In this paper, we apply some ternary near-bent and 2-plateaued functions or r-ary functions to construct more 3-weight ...

MDS Symbol-Pair Repeated-Root Constacylic Codes of Prime Power Lengths Over $\mathbb F_{p^m}+ u \mathbb F_{p^m}$

IEEE Access, 2019
MDS codes have the highest possible error-detecting and error-correcting capability among codes of given length and size. Let p be any prime, and s, m be positive integers.

DNA Code from Cyclic and Skew Cyclic Codes over ${\mathbb{F}}_4\left[v\right]/\langle v^3\rangle$

Entropy, 2023
The main motivation of this work is to study and obtain some reversible and DNA codes of length n with better parameters. Here, we first investigate the structure of cyclic and skew cyclic codes over the chain ring R:=F4[v]/⟨v3⟩.

Comparing the validity of different ICD coding abstraction strategies for sepsis case identification in German claims data. [PDF]

PLoS ONE, 2018
INTRODUCTION:Administrative data are used to generate estimates of sepsis epidemiology and can serve as source for quality indicators. Aim was to compare estimates on sepsis incidence and mortality based on different ICD-code abstraction strategies and ...

On the generalized Hamming weights of certain Reed–Muller-type codes

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
There is a nice combinatorial formula of P. Beelen and M. Datta for the r-th generalized Hamming weight of an a ne cartesian code. Using this combinatorial formula we give an easy to evaluate formula to compute the r-th generalized Hamming weight for a ...

Skew Constacyclic Codes over a Non-Chain Ring

Entropy, 2023
In this paper, we investigate the algebraic structure of the non-local ring Rq=Fq[v]/⟨v2+1⟩ and identify the automorphisms of this ring to study the algebraic structure of the skew constacyclic codes and their duals over this ring. Furthermore, we give a

Complete Characterizations of Optimal Locally Repairable Codes With Locality 1 and $K-1$

IEEE Access, 2019
A locally repairable code (LRC) is a [n, k, d] linear code with length n, dimension k, minimum distance d and locality r, which means that every code symbol can be repaired by at most r other symbols.
