Finite mixture-of-gamma distributions: estimation, inference, and model-based clustering
(SPRINGER HEIDELBERG, 2019)Finite mixtures of (multivariate) Gaussian distributions have broad utility, including their usage for model-based clustering. There is increasing recognition of mixtures of asymmetric distributions as powerful alternatives ... -
Fire history in Andean Araucaria-Nothofagus forests: coupled influences of past human land-use and climate on fire regimes in north-west Patagonia
(CSIRO, 2020)Historical fire regimes are critical for understanding the potential effects of changing climate and human land-use on forest landscapes. Fire is a major disturbance process affecting the Andean Araucaria forest landscape ... -
First Genetic Record of a Strap-Toothed Beaked Whale (Mesoplodon layardii) Stranding in Chile
(Chile. Universidad Mayor, 2020)Of all the cetacean families, the Ziphiidae are one of the most enigmatic (MacLeod, 2018). They are the second most diverse family after the Delphinidae (Dalebout et al., 2002). They dive very deep for prolonged periods, ... -
First record of fossil procyonid (Mammalia, Carnivora) from Uruguay
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)Procyonids were the first carnivorans that arrived from North America to South America during the late Miocene, before the full emergence of the Panama Isthmus. In South America, this family comprises five living genera ... -
First Release of the Bacterial Biobank of the Urban Environment (BBUE)
(AMER SOC MICROBIOLOGY, 2018)Metagenomics is providing a broad overview of bacterial functional diversity; however, culturing and biobanking are still essential for microbiology. Here, we present the Bacterial Biobank of the Urban Environment (BBUE), ... -
First Report of Vibrio tubiashii Associated with a Massive Larval Mortality Event in a Commercial Hatchery of Scallop Argopecten purpuratus in Chile
(CIENCIAS, 2016)The VPAP30 strain was isolated as the highly predominant bacteria from an episode of massive larval mortality occurring in a commercial culture of the Chilean scallop Argopecten purpuratus. The main aims of this study were, ... -
First-Principles Identification of Single Photon Emitters Based on Carbon Clusters in Hexagonal Boron Nitride
(AMER CHEMICAL SOC, 2021-02-18)A recent study associates carbon with single photon emitters (SPEs) in hexagonal boron nitride (h-BN). This observation, together with the high mobility of carbon in h-BN, suggests the existence of SPEs based on carbon ... -
Fisher Information, Weak Values and Correlated Noise in Interferometry
(Cornell University, 2019-02-25)In this article we present an experimental proposal for quantum enhanced estimation of optomechanical parameters. The precision of the estimation is improved by using the technique of weak value amplification, which can ... -
Fishing forward and reverse: Advances in zebrafish phenomics
(ELSEVIER, 2018)Understanding how the genome instructs the phenotypic characteristics of an organism is one of the major scientific endeavors of our time. Advances in genetics have progressively deciphered the inheritance, identity and ... -
Fitness cardiorrespiratorio estimado mediante ecuación y su caracterización sociodemográfica en población chilena: Resultados de la Encuesta Nacional de Salud 2016-2017
(SOC MEDICA SANTIAGO, 2020-12)Background: Cardiorespiratory fitness is a strong predictor of mortality and chronic diseases. However, its estimation is costly and time consuming which may limit it broad use in population-based studies. Aim: To estimate ... -
Flakka use among high school seniors in the United States
(ELSEVIER IRELAND LTD, 2019)Background: Use of synthetic cathinones, commonly referred to as"bath salts", has been associated with tens of thousands of emergency department visits in the US; however, few national studies have estimated prevalence of ... -
Fluid Restriction Decreases Solid Food Consumption Post-Exercise
(MDPI, 2019)Dehydration in rodents induces anorexia. In humans however, the role of dehydration in energy intake is controversial. This study investigated the effect of extreme fluid restriction on acute energy intake during and after ... -
FoamExplorer: Automated measurement of ligaments and voids for atomistic systems
(Elsevier, 2020-12)Atomistic simulations are often used to explore the mechanical and chemical properties of a variety of materials and structures, such as nanowires, whiskers, nanospheres, nanotrusses, and nanoscale foams, among others. ... -
Foetal abuse
(SPRINGER WIEN, 2019)Pregnancy and motherhood are often presented as natural and unproblematic for women. The fact that there are some women who engage in violent behaviour towards their unborn child suggests that motherhood is not as unproblematic ... -
Food sources of added sugar: Brazilian data (EBANS) from Latin American Nutrition and Health Study (ELANS)
(SOC ESPANOLA DIETETICA & CIENCIAS ALIMENTACION-SEDCA, 2019)Introduction: Brazil has the second highest per capita consumption of sugar in the world and added sugar (AS) contributes to 12.6% of the total energy intake. Objective: To investigate the main food sources of AS intake ... -
Forensic identification of the keratin fibers of South American camelids by ambient ionization mass spectrometry: Vicuña, alpaca and guanaco
(John Wiley and Sons Ltd, 2020-12)Rationale The keratin fleece of the endangered vicuna (Vicugna vicugna) commands a high value in international markets, and this trade has caused illegal poaching and a substantial decrease in vicuna populations. Morphological ...
