Trends in the incidence of attention deficit hyperactivity disorder in children and early risk factors

open access: yesJCPP Advances, EarlyView.
Abstract Background Few studies have used nationwide registry data from both primary and secondary healthcare services to examine the incidence of attention‐deficit/hyperactivity disorder (ADHD) in children while accounting for early risk factors. We aimed to investigate trends in ADHD diagnoses and associated risk factors.

PERBANDINGAN KINERJA LDPC PADA KANAL AWGN DENGAN MODULASI QPSK DAN BPSK [PDF]

open access: yes, 2011
Low Density Parity Check (LDPC) codes are one class of linear block coding techniques. The name comes from the characteristics of the LDPC parity check matrix was that only contain a little bit of '1 'if compared with the number of bits of '0'.

Shortened Array Codes of Large Girth

open access: yes, 2006
One approach to designing structured low-density parity-check (LDPC) codes with large girth is to shorten codes with small girth in such a manner that the deleted columns of the parity-check matrix contain all the variables involved in short cycles. This

Risk Factors Associated With the Number of Symptoms and Distress Caused by Genitourinary Syndrome of Menopause in Taiwanese Women

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT A high percentage of women who undergo the transition to postmenopause experience both menopausal symptoms and genitourinary syndrome of menopause (GSM). However, GSM is often underdiagnosed. This research aims to identify risk factors that may influence the number of GSM symptoms and whether they cause distress in Taiwanese women > 45 years ...

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems
In this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property

On Pseudocodewords and Improved Union Bound of Linear Programming Decoding of HDPC Codes [PDF]

open access: yes, 2012
In this paper, we present an improved union bound on the Linear Programming (LP) decoding performance of the binary linear codes transmitted over an additive white Gaussian noise channels. The bounding technique is based on the second-order of Bonferroni-

Potential distribution and susceptibility of Coffea arabica L. to climate change impacts

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Ecological niche models (ENMs) are vital for understanding the impact of historical factors on ecosystems and predicting future climate change scenarios. These models help assess how environmental shifts affect agricultural species like coffee, which supports millions of people globally.

New decoding scheme for LDPC codes based on simple product code structure

open access: yes, 2012
In this paper, a new decoding scheme for low-density parity-check (LDPC) codes using the concept of simple product code structure is proposed based on combining two independently received soft-decision data for the same codeword.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

open access: yesAdvanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.
