Curvature and Tangency Handles for Control of Convex Cubic Shapes (2002)
Figueroa, G., Paluszny, M., Tovar, F.
We consider the problem of modelling a plane convex shape with a closed component of an algebraic non-singular cubic. All nine degrees of freedom are interpreted as visual handles, namely: tangency...
Immunoglobulin G Antibody Response to Infection with Coccoid Forms of Helicobacter pylori
Figueroa, G., Faúndez, G., Troncoso, M., Navarrete, P., Toledo, M. S.
An increasing number of studies support a potential role for coccoid forms in Helicobacter pylori infection. Evidence for this was obtained through scanning microscopy, genetic analysis for virulence...

Analysis of stool samples from 912 cases of diarrhea among Chilean infants and 1,112 controls resulted in the isolation of 17 enteroinvasive Escherichia coli (EIEC) strains from diarrhea cases (1.9%)...
Figueroa, G, Galeno, H, Troncoso, M, Toledo, S, Soto, V
A prospective study of Campylobacter jejuni infection was performed during a 6-month period in a cohort of 198 Chilean infants. Surveillance was based on biweekly home visits by a team of trained...
Depressive symptomatology in northern Mexico adults.
Vega, W A, Kolody, B, Hough, R L, Figueroa, G
A cross-sectional field survey of 991 people in Tijuana, Mexico, a border city experiencing unbridled population growth, was designed to measure levels of depressive symptoms and identify correlates...
