Biometric relations of freshwater fishes of the Suaza River (Huila Department, Colombia) [PDF]

Acta Ichthyologica et Piscatoria, 2016
The knowledge of freshwater fishes in remote Andean mountains is scarce and restricted to changes of occurrence distribution along a specific gradient.

First Confirmed Cooperative Breeding of the Brown Hornbill (Anorrhinus austeni) in China at the Sino–Lao Frontier 中国中老边境尚勇保护区首次记录白喉犀鸟 (Anorrhinus austeni) 的合作繁殖行为

Integrative Conservation, EarlyView.
First confirmed breeding of the Brown Hornbill in China, documented through cooperative feeding in Shangyong Protected Area. ABSTRACT The Brown Hornbill (Anorrhinus austeni), a Near Threatened frugivore, reaches the northern edge of its distribution in southern Yunnan, China, yet breeding had not been previously documented with site‐attributed nests in

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution

IEEE Access
This paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .

On Almost Well-Covered Graphs of Girth at Least 6

, 2018
We consider a relaxation of the concept of well-covered graphs, which are graphs with all maximal independent sets of the same size. The extent to which a graph fails to be well-covered can be measured by its independence gap, defined as the difference ...

Exploring the Dynamics of Ischemia and Reactive Hyperemia With Skeletal Muscle Blood Oxygen Level Dependent MRI in Patients With Peripheral Artery Disease, Age‐Matched Controls, and Young Healthy Subjects

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Skeletal muscle blood oxygen level dependent (BOLD) MRI is a technique for assessing vascular function in peripheral limbs. In patients, however, an increased frequency of atypical response patterns has been observed, warranting investigation into its underlying causes.

A graph and its complement with specified properties III: girth and circumference

International Journal of Mathematics and Mathematical Sciences, 1979
In this series, we investigate the conditions under which both a graph G and its complement G¯ possess certain specified properties. We now characterize all the graphs G such that both G and G¯ have the same girth.

Near-colorings: non-colorable graphs and NP-completeness [PDF]

, 2013
A graph G is (d_1,..,d_l)-colorable if the vertex set of G can be partitioned into subsets V_1,..,V_l such that the graph G[V_i] induced by the vertices of V_i has maximum degree at most d_i for all 1

Lower preoperative Kellgren–Lawrence grade is associated with improved long‐term survivorship following medial meniscus posterior root repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this study was to determine whether there was an association between preoperative Kellgren–Lawrence (KL) grade and long‐term failure rates, reoperation free survival rates, and patient reported outcomes of patients undergoing medial meniscal posterior root repair (MMPRR).

On General Reduced Second Zagreb Index of Graphs

Mathematics, 2022
Graph-based molecular structure descriptors (often called “topological indices”) are useful for modeling the physical and chemical properties of molecules, designing pharmacologically active compounds, detecting environmentally hazardous substances, etc.
