Interfaces between statistical learning and risk management.
(2020)
The recent hype on Artificial Intelligence, Data Science, and Machine Learning has been leading to a revolution in the industries of Banking and Finance. Motivated by this revolution, this
thesis develops novel statistical ...
Clustering dark energy and halo abundances

Dissipative effects in the effective field theory of inflation
(Springer, 2012-01)
We generalize the effective field theory of single clock inflation to include dissipative effects. Working in unitary gauge we couple a set of composite operators, Oµν..., in the effective action which is constrained solely ...

The ALMA Spectroscopic Survey in the HUDF: the Molecular Gas Content of Galaxies and Tensions with IllustrisTNG and the Santa Cruz SAM
(2019)
The ALMA Spectroscopic Survey in the Hubble Ultra Deep Field (ASPECS) provides new constraints for galaxy formation models on the molecular gas properties of galaxies. We compare results from ASPECS to predictions from two ...
Stretching of BDT-gold molecular junctions: thiol or thiolate termination?
(Royal Soc Chemistry, 2014-01-01)
It is often assumed that the hydrogen atoms in the thiol groups of a benzene-1,4-dithiol dissociate when Au-benzene-1,4-dithiol-Au junctions are formed. We demonstrate, by stability and transport property calculations, ...
Distributionally robust optimization: a novel approach with decision-dependent ambiguity sets and an application to mode estimation
(Universidad de los AndesDoctorado en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2023-04-14)
This Ph.D. thesis explores stochastic optimization from a Distributionally Robust perspective, focusing on two significant themes: the innovative use of decision variable-dependent ambiguity sets in Distributionally Robust ...
Effect of magnetism and temperature on the stability of (Crx, V1-x)2AlC phases
(American Physical Society, 2018-12)
The stability of (Crx,V1-x)2AlC MAX phases, materials of interest for a variety of magnetic as well as higherature applications, has been studied using density-functional-theory first-principles calculations. The enthalpy ...
Otimização topológica de estruturas contínuas de polipropileno com restrições de tensão baseadas em critérios de escoamento
(Universidade Federal de Minas GeraisUFMG, 2015-06-25)
This paper develops a stress-based topology optimization method for structures with mechanical properties of polypropylene. This method compares a yield criteria proposed for polypropylene with the yield criteria of the ...
Two component plasma at [gamma] =2 : a random matrix theory semi-application
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2019)
"En este proyecto estudiamos algunos aspectos de la mecánica estadística en equilibrio de un plasma de Coulomb bidimensional de un componente clásico (interacción logarítmica) con simetría circular y N partículas puntuales. ...
