Maximum and minimum degree conditions for embedding trees
We propose the following conjecture: For every fixed alpha is an element of [0, 1/3), each graph of minimum degree at least (1 + alpha)k/2 and maximum degree at least 2(1 - alpha)k contains each tree with k edges as a ...
The asymmetry and the optimization degree of the airway of Rattus norvegicus and Oryctolagus cuniculus La asimetría y el grado de optimización del árbol bronquial en Rattus norvegicus y Oryctolagus cuniculus
From a physical perspective, the air way has been proposed as a model of optimal design. Its design has been associated with a optimal gases flow to the alveoli, a minimum entropy production and minimal costs of mass and ...
Climate change projections of temperature and precipitation in Chile based on statistical downscaling
General circulation models (GCMs) allow the analysis of potential changes in the climate system under different emissions scenarios. However, their spatial resolution is too coarse to produce useful climate information for ...
Cold tolerance mechanisms of two arthropods from the andean range of Central Chile: agathemera crassa (insecta: agathemeridae) and euathlus condorito (arachnida: theraphosidae)
Two strategies have been described for cold tolerance in arthropods: (1) freeze-tolerant organisms, which can survive the formation of ice crystals and (2) freeze-avoidant organisms, which prevent the ice crystal formation ...
Periacetabular osteotomy with concomitant hip arthroscopy: a case series with 24 months minimum follow-up
Purpose To describe patient-reported outcomes, radiological results, and revision to total hip replacement in patients with hip dysplasia that underwent periacetabular osteotomy as isolated treatment or concomitant with ...
Distance measures, weighted averages, OWA operators and Bonferroni means
The ordered weighted average (OWA) is an aggregation operator that provides a parameterized family of operators between the minimum and the maximum. This paper presents the OWA weighted average distance operator. The main ...
A Comparison of Two Methodological Approaches for Determining Castor Bean Suitability in Chile
Castor bean (Ricinus communisL.) contains ricinoleic acid, making it one of the world's most important oil-seeds. There are few studies on this species in Chile, despite its potential as an industrial crop. This study ...
Another upper bound for the domination number of a graph
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1986)
If δ and ∆ are the minimum and máximum degrees of a simple graph G of size n, then, for its domination number B(G), we show that B(G) ≤ [(n-∆-1) (n- δ-2)/(n-1)]+2.
Solitons in a modified discrete nonlinear Schrödinger equation
(Nature Publishing Group, 2018)
© 2018 The Author(s). We study the bulk and surface nonlinear modes of a modified one-dimensional discrete nonlinear Schrödinger (mDNLS) equation. A linear and a modulational stability analysis of the lowest-order modes ...
Induced OWA operators in linear regression
(IOS Press, 2020)
The induced ordered weighted average (IOWA) is an aggregation operator that provides a parameterized family of operators between the minimum and the maximum. This work presents a new application that uses the simple linear ...
