(SPRINGER, 2008-04)Invasive species can increase fire frequency and intensity, generating favorable conditions for their self-perpetuation. Mediterranean south-central Chile may be especially prone to the effects of invasive species on fire ...
-
(Nature Publishing Group, 2017)Door-to-needle time (DNT) is a key performance indicator for efficient use of intravenous thrombolysis in acute ischemic stroke (AIS). We aimed to determine whether DNT improved over time in the Enhanced Control of ...

(BLACKWELL, 2006-01)In alpine habitats, positive interactions among plants tend to increase with elevation as a result of altitudinal increase in environmental harshness. However, in mountains located in arid zones, lower elevations are also ...

(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004-05-20)In this article we prove existence of positive radially symmetric solutions for the nonlinear elliptic equation M-lambda,Delta(+)(D(2)u) - gammau + f(u) = 0 in B-R, u = 0 on partial derivativeB(R), where M-lambda,Delta(+) ...
-
(Nature, 2022)Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong ...

Positive solutions for systems of quasilinear equations with non-homogeneous operators and weights (Walter de Gruyter, 2020)In this paper we deal with positive radially symmetric solutions for a boundary value problem containing a strongly nonlinear operator. The proof of existence of positive solutions that we give uses the blow-up method as ...
-
(Heldermann, 2016)We consider the general class of positively alpha-far sets, introduced in [29], which contains strictly the class of uniformly prox-regular sets and the class of uniformly subsmooth sets. We provide some conditions to ...
-
(Nature Publishing, 2018-06-27)Equiatomic flower-like FeCo magnetic nanoparticles are synthesized through a modified one-pot polyol technique. The as-prepared samples are annealed at 700 and 800 degrees C under reducing atmosphere. The saturation ...

(2012)Background: The usefulness of positron emission tomography (PET) with fluorine-deoxyglucose (FDG) in sarcomas and non-sarcoma non-epithelial (NSNE) tumors is not clearly defined. Aim: To report a Chilean experience with ...
-
(Elsevier Inc., 2017)© 2016 Elsevier Inc. Purpose To assess the predictive value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) for disease recurrence after immunochemotherapy (R-CHT) and mediastinal ...

(2011)Paratuberculosis is a chronic intestinal disease of animals caused by Mycobacterium avium subsp. paratuberculosis (MAP), which has some pathological features similar to Crohn's disease (CD) in humans. The presence of MAP ...
-
(Wiley Blackwell, 2019)Odor transduction in the cilia of olfactory sensory neurons involves several ATP-requiring enzymes. ATP is generated by glycolysis in the ciliary lumen, using glucose incorporated from surrounding mucus, and by oxidative ...
-
(2013-06)We perform numerical simulations to study a formation scenario for dwarf spheroidal (dSph) galaxies in which their stellar populations are the products of the dissolution of open star clusters and stellar associations ...
-
(Oxford University Press, 2013)Dwarf spheroidal (dSph) galaxies are considered the basic building blocks of the galaxy formation process in the Lambda cold dark matter hierarchical cosmological model. These galaxies are believed to be the most dark ...

Possible involvement of the phloem sealing system in the acceptance of a plant as host by an aphid (Birkhauser Verlag AG, 1996)Possible reasons for the rejection of some lines of Triticum monococcum (Tm44 and Tm46) by the aphid Sitobion avenae were explored. In all T. monococcum lines studied, whether unfavourable (non-host/resistant plant) or ...

(EDP Sciences, 2015)A complete understanding of the origin of the prestellar core mass function (CMF) is crucial. Two major features of the prestellar CMF are 1) a broad peak below 1M(circle dot), presumably corresponding to a mean gravitational ...
