Analysis of Fermi-LAT observations, UHECRs and neutrinos from the radio galaxy Centaurus B
(2019-08-20)
Centaurus B (Cen B) is one of the closest and brightest radio-loud galaxy in the southern sky. This radio galaxy, proposed as a plausible candidate for accelerating ultra-high-energy cosmic rays (UHECRs), is near the ...
Bocaparvovirus, Erythroparvovirus and Tetraparvovirus in New World Primates from Central America
(2020)
Parvoviruses in the genera Bocaparvovirus (HBoV), Erythroparvovirus (B19) and Tetraparvovirus (PARV4) are the only autonomous parvoviruses known to be associated with human and non‐human primates based on studies and ...
Temperature and elemental sulfur shape microbial communities in two extremely acidic aquatic volcanic environments
(2021)
Aquatic environments of volcanic origin provide an exceptional opportunity to study the adaptations of microbial communities to early planet life conditions such as high temperatures, high metal concentrations, and low pH. ...
A partial differential equation model with age-structure and nonlinear recidivism: Conditions for a backward bifurcation and a general numerical implementation
(2019-12-15)
We formulate an age-structured three-staged nonlinear partial differential equation model that features nonlinear recidivism to the infected (infectious) class from the temporarily recovered class. Equilibria are computed, ...
Parameter estimates of the 2016-2017 Zika outbreak in Costa Rica: An Approximate Bayesian Computation (ABC) approach
(2019-03-28)
In Costa Rica, the first known cases of Zika were reported in 2016. We looked at the 2016-2017 Zika outbreak and explored the transmission dynamics using weekly reported data. A nonlinear differential equation single-outbreak ...
Phylogenetic analysis of ITS data from endophytic fungi using massive parallel bayesian tree inference with exabayes
Análisis filogenético de secuencias ITS provenientes de hongos endófitos utilizando inferencia bayesiana paralela de árboles con exabayes
(2020-03-27)
Ecological studies of fungal communities have been favored thanks to the emergence and improvement of independent culture techniques that use the ITS region as a molecular marker. This has allowed a more accurate identification ...
Two new species of Rhagovelia (Hemiptera: Heteroptera: Veliidae) from Costa Rica, with a key and new records from the country
(2015)
Rhagovelia danpolhemi sp. nov., from the Caribbean Slope of Costa Rica and R. springerae sp. nov., from the northern portion of the country, are described, illustrated, compared with similar species, and included in a key ...
A source of gamma rays coincident with the shell of the supernova remnant CTB 80
(2021)
CTB 80 (G69.0+2.7) is a relatively old (50–80 kyr) supernova remnant (SNR) with a complex radio morphology showing three extended radio arms and a radio and X-ray nebula near the location of the pulsar PSR B1951+32. We ...
Reproducible molecular networking of untargeted mass spectrometry data using GNPS
(2020-05-13)
Global Natural Product Social Molecular Networking (GNPS) is an interactive online small molecule–focused tandem mass spectrometry (MS2) data curation and analysis infrastructure. It is intended to provide as much chemical ...
New records of Gerromorpha (Insecta: Hemiptera: Heteroptera) from Costa Rica
(2014-02-01)
The Gerromorpha from Costa Rica are poorly studied, except the Gerridae. Aiming to fill this gap, specimens collected across the country were examined. Lipogomphus leucostictus, Hydrometra alloiona, H. australis, H. ...
