Experimental validation of gallium production and isotope-dependent positron range correction in PET
(Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment vol.814 110-116 2016, 2016-04-01)
Positron range (PR) is one of the important factors that limit the spatial resolution of positron emission tomography (PET) preclinical images. Its blurring effect can be corrected to a large extent if the appropriate ...
Characterization of the VARIAN®PaxScan 2020+ flat panel detector for quantitative X-ray imaging
(X-Ray Spectrometry vol.45 no.3 169-175 2016, 2016-02-19)
In this work, the response of the VARIAN® PaxScan 2020+ flat panel detector was characterized in terms of spatial resolution and uniformity across the detection area along with detection efficiency for photon beams from ...
A Collaborative Effort Between Caribbean States for Tsunami Numerical Modeling: Case Study CaribeWave15
(Pure and Applied Geophysics vol.175 no.2 1405-1428 2017, 2017)
Historical records have shown that tsunami have affected the Caribbean region in the past. However infrequent, recent studies have demonstrated that they pose a latent hazard for countries within this basin. The Hazard ...
Numerical Simulations of the 1991 Limón Tsunami, Costa Rica Caribbean Coast
(Pure and Applied Geophysics vol.174 2945-2959 2017, 2017)
The second largest recorded tsunami along the Caribbean margin of Central America occurred 25 years ago. On April 22nd, 1991, an earthquake with magnitude Mw 7.6 ruptured along the thrust faults that form the North Panama ...
Tsunamis Recorded in Tide Gauges at Costa Rica Pacific Coast and their Numerical Modeling
(2017)
Resumen Aquí realizamos un inventario de tsunamis registrado por mareógrafos en la costa del Pacífico de Costa Rica. Este documento también revela nueve registros de tsunamis que no se habían publicado antes, en el indicador ...
Slow westward movement of salinity anomalies across the tropical South Indian Ocean
(American Geophysical Union, 2015-08-06)
Decadal salinity variability is an important characteristic of the ocean. It characterizes differences in evaporative and precipitation fluxes at the surface, and in the subsurface it contributes to steric sea level change ...
Electrochemical Hydrogen Oxidation on Pt(100): a Combined Direct Molecular Dynamics/Density Functional Theory Study
(Electrocatalysis, 2015-08-09)
We have studied the hydrogen oxidation reaction on various catalytic sites at the water/Pt(100) interface with first-principles direct molecular dynamics and minimum energy pathway calculations. The calculations indicate ...
Evaluation of volume change in rectum and bladder during application of image-guided radiotherapy for prostate carcinoma
(AIP Conference Proceedings, 2016-07-07)
All prostate cancer patients from Centro Médico Radioterapia Siglo XXI receive Volumetric Modulated Arc Therapy (VMAT). This therapy uses image-guided radiotherapy (IGRT) with the Cone Beam Computed Tomography (CBCT). This ...
Evaluating SODA for Indo-Pacific Ocean decadal climate variability studies
(Journal of Geophysical Research: Oceans, 2014-10-31)
Estimates of changes in upper ocean temperature, heat content, and sea level are dependent on the coverage of subsurface observations in space and time. Historically, these data are sparse, which has limited our understanding ...
A combined experimental and theoretical study of gas sorption on nanoporous silver triazolato metal-organic frameworks
(2014-01-01)
A new silver-triazolate metal-organic framework (MOF), {Ag 3[Ag5(μ3-3,5-tBu 2tz)6](BF4)2}n (2), has been prepared and structurally characterized. The CO2 sorption properties of this new MOF and previously reported isostructural ...
