Hundreds of nuclear and plastid loci yield novel insights into orchid relationships
(2021)PREMISE: The inference of evolutionary relationships in the species- rich family Orchidaceae has hitherto relied heavily on plastid DNA sequences and limited taxon sampling. Previous studies have provided a robust plastid ... -
Hybrid mathematical modeling decodes the complexity of sphingolipid pathway to predict chemosensitivity
(2017)Sphingolipid (SL) signaling pathway is a complex biological system able to integrate different types of cellular stress signals related to induction of cell death pathways with special interest in cancer. This makes of ... -
Hybrid speech enhancement with wiener filters and deep LSTM denoising autoencoders
(2018)Over the past several decades, numerous speech enhancement techniques have been proposed to improve the performance of modern communication devices in noisy environments. Among them, there is a large range of classical ... -
Hydration Status and Fluid Intake Habits of Fitness Enthusiasts
(2006-05)PURPOSE: To determine the hydration status (HS) and its relation with fluid intake habits (FIH), and exercise variables of fitness enthusiasts before one exercise session on different times of the day, at three different ... -
(Hydro)climatological studies of climate change and variability in Central America
(2018-06-26)This is the presentation of Hugo Hidalgo at the CORDEX Central America and South America Training Workshop on Downscaling Techniques, in La Paz, Bolivia, June 25 to 27, 2018. -
Hydro-Climatic Variability and Change in Central America. Supporting Risk Reduction Through Improved Analyses and Data
(2017)Floods and droughts are frequent in Central America and cause large social, economic and environmental impacts. A crucial step in disaster risk reduction is to have a good understanding of the causing mechanisms of extreme ... -
Hydrocarbon Degrading Microflora in a Tropical fuel-Contaminated Aquifer: Assessing the Feasibility of PAH Bioremediation
(2012-01)An aquifer located within a petroleum processing plant in Moín, Costa Rica, suffers hydrocarbon pollution. This study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic ... -
Hydrogen production by immobilized Synechocystis sp. PCC 6803
(2016)The ability of the immobilized Synechocystis sp. PCC 6803 cells to produce hydrogen via an indirect light driven process was investigated. Cells were successfully immobilized in a calcium alginate gel matrix. Beads were ... -
Hydrologic Modeling Analysis from Land Use Scenario Changes in Quebrada Seca and Bermudez Watershed
(2014-07)During the last few years, the expansion of urban cover in the Quebrada Seca-Bermudez watershed has caused a series of floods that have damaged houses, bridges, and other important infrastructure of the area. Hence local ... -
Hydrological climate change projections for Central America
(Journal of Hydrology 495: 94–112, 2013-05-04)Runoff climate change projections for the 21st century were calculated from a suite of 30 General Circulation Model (GCM) simulations for the A1B emission scenario in a 0.5 0.5 grid over Central America. The GCM data ... -
Hydrology Affects Environmental and Spatial Structuring of Microalgal Metacommunities in Tropical Pacific Coast Wetlands
(2016-02-22)The alternating climate between wet and dry periods has important effects on the hydrology and therefore on niche-based processes of water bodies in tropical areas. Additionally, assemblages of microorganism can show spatial ... -
Hydrometeorological disasters in urban areas of Costa Rica, Central America
(2020)Tropical countries are subjected to natural disasters which cause substantial human and economic losses. Coping with disasters in tropics requires to improve our understanding of the frequency and distribution of ...
