On the tractability of shortest path problems in weighted edge-coloured graphs
(2018)A weighted edge-coloured graph is a graph for which each edge is assigned both a positive weight and a discrete colour, and can be used to model transportation and computer networks in which there are multiple transportation ...

On the uniqueness of semi-wavefronts for non-local delayed reaction–diffusion equations
(2015)We establish the uniqueness of semi-wavefront solution for a non-local delayed reaction–diffusion equation. This result is obtained by using a generalization of the Diekmann–Kaper theory for a nonlinear convolution equation. ...

On uniqueness of semi-wavefronts: Diekmann–Kaper theory of a nonlinear convolution equation re-visited
(2012)Motivated by the uniqueness problem for monostable semi-wave -fronts, we propose a revised version of the Diekmann and Kaper theory of a nonlinear convolution equation. Our version of the Diekmann–Kaper theory allows (1) ...

Onset of schizophrenia diagnoses in a large clinical cohort
(2019)We aimed to describe the diagnostic patterns preceding and following the onset of schizophrenia diagnoses in outpatient clinics. A large clinical sample of 26,163 patients with a diagnosis of schizophrenia in at least one ...

Open naturalism and two types of intuition
(2024)As a non-representationalist form of integrating methodological naturalism with ontological naturalism, this work proposes a distinction between phenomenic and rational intuitions. Since this is not a static distinction, ...

Operacionalización del modelo función-disfunción: Un acercamiento hacia la "pretensión" de la autonomía profesional
(2011)La disponibilidad de un modelo epistemológico que permita orientar una mejor práctica, es una necesidad que demanda la exposición transparente de las bases teóricas que lo sostienen en diversos contextos con el fin de ...

Optimal activation ratio of the scapular muscles in closed kinetic chain shoulder exercises: A systematic review
(2021)BACKGROUND: Muscle synergies contribute to scapular position during arm movement. The trapezius and serratus anterior (SA) muscles are the main stabilizers and are therefore the main target muscles of therapeutic ...

Optimal cut-off points for waist circumference in the definition of metabolic syndrome in Chile.
(2020)Objective: To identify sex-specific cut-off points for waist circumference (WC) in the definition of metabolic syndrome (MetS) for the Chilean adult population. Design: MetS was defined as the presence of at least two out ...

Optimal management strategies to maximize carbon capture in forest plantations: a case study with pinus radiata D. Don
(2023)Plantations with fast-growing species play a crucial role in reducing global warming and have great carbon capture potential. Therefore, determining optimal management strategies is a challenge in the management of forest ...
-
Optimal rotation age in fast growing plantations: a dynamical optimization problem
(2024)Forest plantations are economically and environmentally relevant, as they play a key role in timber production and carbon capture. It is expected that the future climate change scenario affects forest growth and modify the ...

Optimizing fresh food logistics for processing: Application for a large Chilean apple supply chain
; Gonzalez-Araya, Marcela
; ; (2017)
This research paper presents optimization models that deal with three kinds of related decisions in horticulture, which are purchasing, transporting and storing fresh produce. The study is intended to assist in decision ...

Optimizing tactical harvest planning for multiple fruit orchards using a metaheuristic modeling approach
(2021)In a fruit harvest season, the fruit must be collected during a relatively short period of intense activity. Moreover, large fruit export companies commonly manage multiple orchards where the resources and labor are shared, ...

Oxidative conditions along the continental shelf of the Southeast Pacific during the last two millennia: a multiproxy interpretation of the oxygen minimum zone variability from sedimentary records
(2023)The oxygen minimum zone (OMZ) is an essential feature along the Pacific margin, extensively studied for its influence on benthic fauna, acquiring relevance in coastal zones due to its impact on aquaculture species, ...

Oxide nanolitisation-induced melt iron extraction causes viscosity jumps and enhanced explosivity in silicic magma
(2024)Explosivity in erupting volcanoes is controlled by the degassing dynamics and the viscosity of the ascending magma in the conduit. Magma crystallisation enhances both heterogeneous bubble nucleation and increases in magma ...

Oxygen minimum zone variability during the last 700 years in a coastal upwelling area of the Humboldt system (Mejillones, 23° S, Chile). A new approach from geochemical signature
(2021)Mejillones bay presents a permanent and shallow OMZ, whose upper boundary fluctuates between 30 m and 60 m water depth during a normal year. Under this condition, the bottom sediments preserve a geochemical signature of ...
