Fiducial Stellar Population Sequences for the VJKs Photometric System
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2010/12/23
We have obtained broad-band near-infrared photometry for seven Galactic star clusters (M92, M15, M13, M5, NGC1851, M71 and NGC6791) using the WIRCam wide-field imager on the Canada-France-Hawaii Teles...
Mathematical analysis of a two-dimensional population model of metastatic growth including angiogenesis
2D structured populations semigroup asymptotic behavior malthus parameter
2010/12/6
Angiogenesis is a key process in the tumoral growth which allows the cancerous tissue to impact on its vasculature in order to improve the nutrient’s supply and the metastatic process. In this paper, ...
DC-switchable and single-nanocrystal-addressable coherent population transfer
DC-switchable single-nanocrystal-addressable coherent population transfer
2010/10/21
Achieving coherent population transfer in the solid-state is challenging compared to atomic systems due to closely spaced electronic states and fast decoherence. Here, within an atomistic pseudopotent...
Smaller population size at the MRCA time for stationary branching processes
Branching process most recent common ancestor bottleneck genealogy
2010/11/30
We present an elementary model of random size varying population given by a stationary continuous state branching process. For this model we compute the joint distribution
of: the time to the most re...
Implications of warming temperatures for population outbreaks of a nonindigenous species (Membranipora membranacea, Bryozoa) in rocky subtidal ecosystems
Implications of warming temperatures population outbreaks of a nonindigenous species Membranipora membranacea, Bryozoa rocky subtidal ecosystems
2014/4/17
To quantify and explore the role of temperature on population outbreaks of a nonindigenous bryozoan (Membranipora membranacea) in kelp beds in the western North Atlantic (Nova Scotia, Canada), we cons...
Analysis of volcanic threat from Nisyros Island, Greece, with implications for aviation and population exposure
Analysis volcanic threat Nisyros Island Greece implications aviation population exposure
2010/10/20
Nisyros island in the South Aegean volcanic arc, Greece, is a Quaternary composite volcano with a 3.8 km wide caldera that in 1996 entered a volcano-seismic crisis, which heralded the islands' return ...

Genetic Parameters Litter Traits Service Interval Swine Trends Tropical
2016/5/4
The objectives of this research were the estimation of genetic parameters and trends for weaning-to-first service interval (WSI), and litter traits in a commercial swine population composed of Landrac...
Detection of Quantitative Trait Loci for Growth and Carcass Traits on BTA6 in a Hanwoo Population
QTL BTA6 Growth Carcass Traits Hanwoo
2016/5/4
The purpose of this study was to detect quantitative trait loci (QTL) for growth and carcass quality traits on BTA6 in a population of Hanwoo cattle. Three hundred and sixty one steers were produced f...
Interactions between limiting nutrients: Consequences for somatic and population growth of Daphnia magna
Interactions between limiting nutrients population growth of Daphnia magna
2014/4/17
To assess the significance of nutrient interactions on animal performance, life-history experiments were
conducted with the freshwater herbivore Daphnia magna in a system with two limiting nutrients ...
Rapid evolution of phenoloxidase expression, a component of innate immune function, in a natural population of Daphnia magna
Rapid evolution phenoloxidase expression innate immune function in a natural population Daphnia magna
2014/4/17
We show rapid microevolution of one component of invertebrate innate immunity, phenoloxidase activity, in a natural population of the water fleaDaphnia magna.InDaphniahatched out of different depths o...
