Valid and practical methods based on healthrelated
criteria for obesity screening in children and adolescents
are not available. Arbitrarily defined body mass index (BMI) cutoffs
have been proposed...
Differentiation of the disease caused by Aphanomyces cochlioides and girth scab on sugar beet roots – a review
description Pythium Aphanomyces root rot Streptomyces symptoms
2017/4/6
Severe symptoms of root rot on sugar beet have been observed in Poland and Germany since 2001. The symptom classification suggested girth scab as it was mistakenly classified on the basis of current c...
We present a simple and efficient algorithm for randomly generating simple graphs without small cycles. These graphs can be used to design high performance Low-Density Parity-Check (LDPC) codes. ...
Eight weeks of supplementation with a multi-ingredient weight loss product enhances body composition,reduces hip and waist girth,and increases energy levels in overweight men and women
Dietary supplement Raspberry ketone Adipokine Body composition Fat loss Capsaicin
2015/7/27
Numerous natural products are marketed and sold claiming to decrease body weight and fat, but few undergo finished product-specific research demonstrating their safety and efficacy.To determine the sa...
Recently, it has been shown that a connected graph $\Gamma$ with $d+1$ distinct eigenvalues and odd-girth $2d+1$ is distance-regular. The proof of this result was based on the spectral excess theorem....
1-Tb/s Large Girth LDPC-Coded Coherent Optical OFDM Transmission over 1040-km Standard Single-Mode Fiber
Large Girth LDPC-Coded Coherent Optical OFDM Standard Single-Mode Fiber
2015/5/15
We experimentally demonstrate 1-Tb/s CO-OFDM transmission over 1040-km standard single-mode fiber using 50% overhead girth-12 LDPC-coded 16-QAM. More than 4-dB improvement in OSNR sensitivity is achie...
Extremal results regarding $K_6$-minors in graphs of girth at least 5
Extremal results regarding $K_6$-minors graphs of girth
2011/2/28
We prove that every 6-connected graph of girth ≥ 6 has a K6-minor and thus settle Jorgensen’s
conjecture for graphs of girth ≥ 6. Relaxing the assumption on the girth, we prove that every
6-connecte...
Minimizing Laplacian spectral radius of unicyclic graphs with fixed girth
Laplacian matrix Laplacian spectral radius girth unicyclic graph
2011/1/18
In this paper we consider the following problem: Over the class of all simple con-nected unicyclic graphs on n vertices with girth g (n, g being fixed), which graph minimizes the Laplacian spectral ra...
We present a generalization of the construction of graphs by Lubotzky, Phillips and Sarnak in their celebrated article "Ramanujan graphs". The new approach consists in using octonion algebras rather ...
Girth-8 (3,L)-规则QC-LDPC码的一种确定性构造方法
低密度奇偶校验码 准循环 围长
2010/5/6
对于围长(girth)至少为8的低密度奇偶校验(LDPC)码，目前的绝大多数构造方法都需要借助于计算机搜索。受贪婪构造算法启发，该文利用完全确定的方式构造出一类围长为8的(3, L)- 规则QC-LDPC码。这类QC-LDPC码的校验矩阵由3×L个P×P的循环置换矩阵构成。对于任意整数P≥3L2/4，这类校验矩阵的围长均为8。
