First wave of SARS-CoV-2 in Santiago Chile: Seroprevalence, asymptomatic infection and infection fatality rate
(2022)
Background: The first wave of SARS-CoV-2 infection in Chile occurred during the cold season reaching a peak by the end of June 2020, with 80 % of the cases concentrated in its capital, Santiago. The main objective of this ...
Asymptotic solutions of the problem of steep capillary-gravitational Faraday waves on the interface between fluids
(2004)
We construct asymptotic solutions of the 2D problem on weakly nonlinear capillary-gravitational Faraday waves and the interface between two fluids (of distinct density) subjected to vertical oscillations. The problem is ...

The mechanical waves conceptual survey: An analysis of university students' performance, and recommendations for instruction
(Modestum, 2017-01-01)
The Mechanical Waves Conceptual Survey (MWCS), presented in 2009, is the most important test to date that has been designed to evaluate university students' understanding of four main topics: propagation, superposition, ...
A high performance 650-GHz sideband separating mixer design and results
(IEEE Inst Electrical and Electronic Engineering Inc., 2017)
We presented the design and experimental results of a new sideband-separating (2SB) mixer for 600-720 GHz (ALMA Band 9). Although designed following the classical quadrature hybrid architecture, the emphasis of the ...
