Maximum and minimum degree conditions for embedding trees
(Siam, 2020)
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 ...
Patterns of endemism in south-eastern Pacific benthic polychaetes of the Chilean coast
(BLACKWELL, 2006-04)
Aim In this study we evaluate patterns of endemism for benthic polychaete species along the southeastern Pacific coast of Chile. Our goals were (1) to describe latitudinal gradients of endemism and identify areas of high ...
FORCING LARGE COMPLETE (TOPOLOGICAL) MINORS IN INFINITE GRAPHS∗
(Society for Industrial and Applied Mathematics, 2013)
It is well known that in finite graphs, large complete minors/topological minors can
be forced by assuming a large average degree. Our aim is to extend this fact to infinite graphs. For
this, we generalize the notion of ...
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
(2002)
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 ...
Complexity of splits reconstruction for low-degree trees
(Elsevier, 2015)
Given a vertex-weighted tree T , the split of an edge e in T is the minimum over the weights
of the two trees obtained by removing e from T , where the weight of a tree is the sum of
weights of its vertices. Given a set ...
Systems to establish bioclimatic analogies to predict the area of adaptability of plant species to new environments: The case of Moringa oleifera Lam. in Chile
(Instituto de Investigaciones Agropecuarias, 2015)
Adaptability of a species to new territories is generally assessed by costly trial and error in situ experiments distributed throughout different agroclimatic environments. Nowadays climatic data are available to allow the ...
Three-dimensional density model of the Nazca plate and the Andean continental margin
(AMER GEOPHYSICAL UNION, 2006-09-26)
We forward modeled the Bouguer anomaly in a region encompassing the Pacific Ocean (85 degrees W) and the Andean margin (60 degrees W) between northern Peru (5 degrees S) and Patagonia (45 degrees S). The three-dimensional ...
Climate change projections of temperature and precipitation in Chile based on statistical downscaling
(Springer, 2020)
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 ...
Periacetabular osteotomy with concomitant hip arthroscopy: a case series with 24 months minimum follow-up
(Medwave, 2020)
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
(Elsevier, 2017)
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 ...
