Government Turnover and External Financial Assistance
(Universidad Torcuato Di Tella, 2023)We study the political incentives shaping governments’ decisions to seek assistance from a lender of last resort. We propose that re-elected incumbents are more reluctant than newly elected governments to request assistance, ... -
NORHA: A NORmal Hippocampal Asymmetry Deviation Index Based on One-Class Novelty Detection and 3D Shape Features
(Brain TopographySpringer, 2023)Radiologists routinely analyze hippocampal asymmetries in magnetic resonance (MR) images as a biomarker for neurodegenerative conditions like epilepsy and Alzheimer’s Disease. However, current clinical tools rely on either ... -
A better alignment between chronotype and school timing is associated with lower grade retention in adolescents
(NPJ Science of Learning, 2023)Schools start early in the morning all over the world, contrasting with adolescents’ late chronotype. Interestingly, lower academic performance (i.e. grades or qualifications) was associated with later chronotypes. However, ... -
The presence of irrelevant alternatives paradoxically increases confidence in perceptual decisions
(Cognition, 2023)Confidence in perceptual decisions is thought to reflect the probability of being correct. According to this view, confidence should be unaffected or minimally reduced by the presence of irrelevant alternatives. To test ... -
Facet-generating procedures for the maximum-impact coloring polytope
(2023)Given two graphs G = (V, EG) and H = (V, EH) over the same set of vertices and given a set of colors C, the impact on H of a coloring c : V → C of G, denoted I(c), is the number of edges ij ∈ EH such that c(i) = c(j). ... -
The maximum 2D subarray polytope: facet-inducing inequalities and polyhedral computations
(2022)Given a matrix with real-valued entries, the maximum 2D subarray problem consists in finding a rectangular submatrix with consecutive rows and columns maximizing the sum of its entries. In this work we start a polyhedral ... -
Bone-GAN: Generation of virtual bone microstructure of high resolution peripheral quantitative computed tomography
(Medical PhysicsAmerican Association of Physicists in Medicine, 2023)Background:Data-driven development of medical biomarkers of bone requires a large amount of image data but physical measurements are generally too restricted in size and quality to perform a robust training. Purpose: ...
