Energy exchange between atoms with a quartz crystal μ-balance
(2018)
We propose an experimental method to fully characterize the energy exchange of particles during the
physical vapor deposition (PVD) process of thin surface layers. Our approach is based on the careful
observation of ...
HAWC and Fermi-LAT detection of extended emission from the unidentified source 2HWC J2006+341
(2020)
The discovery of the TeV point source 2HWC J2006+341 was reported in the second HAWC gamma-ray catalog. We present a follow-up study of this source here. The TeV emission is best described by an extended source with a soft ...
Determination of the dosimetric characteristics of a new polymer-encapsulated, elongated, 103Pd brachytherapy source using Monte Carlo calculations
(2009)
Purpose: To use Monte Carlo calculations to determine the dosimetric characteristics of CivaString, a new polymer-encapsulated, elongated, 103Pd brachytherapy source made by Civatech Oncology for prostate implants. This ...
GeV Emission in the Region of the Supernova Remnant G51.26+0.11
(2021-11-02)
The supernova remnant G51.26+0.11 was recently discovered and little is known about its properties and environment. Using data from the Fermi Large Area Telescope we study the GeV emission seen in the direction of G51.26+0.11 ...
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 ...

Vacuum treatment to stabilize oxidation at low temperature region in porous silicon
(2020)
Oxidation in porous silicon is studied for as-etched samples and samples subjected to high vacuum at room temperature. Attenuated Total Reflectance (ATR) measurements in infrared spectroscopy for temperatures ranging from ...
Tropical easterly waves over Costa Rica and their relationship to the diurnal cycle of rainfall
(2023-01)
Using an index of tropical easterly wave (TEW) activity derived from spacetime-filtered outgoing longwave radiation, we construct composites of long-term hourly surface meteorological observations and morningtime sounding ...
Optical component
(2010-02-15)
El invento trata de un componente óptico, que comprende un primer reflector esférico y un segundo reflector esférico, el cual está colocado para reflejar un rayo de luz varias veces entre el primer reflector y el segundo ...
The High-Altitude water cherenkov (HAWC) observatory in México: The primary detector
(2023-07)
The High-Altitude Water Cherenkov (HAWC) observatory is a second-generation continuously operated, wide field-of-view, TeV gamma-ray observatory. The HAWC observatory and its analysis techniques build on experience of the ...
