Generalized Moment Estimation Of Stochastic Differential Equations
(Springer HeidelbergHeidelberg, 2016)
Assessing misspecified asset pricing models with empirical likelihood estimators
(Elsevier Science Sa, 2012-10)
Hansen and Jagannathan (1997) compare misspecified asset pricing models based on least-square projections on a family of admissible stochastic discount factors. We extend their fundamental contribution by considering Minimum ...
Economic implications of nonlinear pricing kernels
(FGV EPGE, 2017-10)
Based on a family of discrepancy functions, we derive nonparametric stochastic discount factor bounds that naturally generalize variance, entropy, and higher-moment bounds. These bounds are especially useful to identify ...
Quiet-condition variations in the scale height at F2-layer peak at Jicamarca during solar minimum and maximum
(European Geosciences Union (EGU), 2008-01-02)
This study is the first attempt to examine the quiet-condition variations in scale height (Hm) near the F2-layer peak in the equatorial ionosphere. The data periods of Hm derived from the Jicamarca ionograms are January-December ...
Evaluating future climate change exposure of marine habitat in the South East Pacific based on metabolic constraints
(Frontiers Media, 2023-01-05)
On-going climate change is now recognized to yield physiological stresses on marine species, with potentially detrimental effects on ecosystems. Here, we evaluate the prospect of using climate velocities (CV) of the metabolic ...
Functional responses to edge effects: Seed dispersal in the southern Atlantic forest, Argentina
(Elsevier Science, 2014-09)
Recent studies have advanced our understanding of the mechanisms behind population and community responses to edge effects. However, functional responses remain poorly explored. Seed dispersal is a key process in ecosystem ...
Estudo do diagnóstico por angiotomografia para tromboembolismo pulmonar em um hospital geral
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA NUCLEARPrograma de Pós-Graduação em Ciências e Técnicas NuclearesUFMG, 2019-06-25)
Angiotomography for Pulmonary Thromboembolism (AngioTEP) is an examination with very fast scan time and with many details to follow. There are great difficulties in establishing standardized procedures for performing this ...
Implementação de beamformer adaptativo combinado com generalized sidelobe canceler e filtros para geração de imagens de ultrassom com ondas planas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2020-02-28)
Adaptive beamformer methods have been improving image processing by the Delay and Sum (DAS) method, with increasing resolution and contrast. Even so, the Minimum Variance (MV) method has much to be improved. Thus, new ...
Abordagem contrastiva na terapia para desvios fonológicos: considerações teóricas
(Universidade Federal de Santa MariaCentro de Ciências da Saúde, 2007-01-17)
Phonological disorders are alterations that occur in the speech of some children and are characterized by substitutions and/or omissions of phonemes. It is really important that the speech therapist, after detailed assessment, ...
Comparação entre metodologias de controle de qualidade em mamografia digital
(Universidade Estadual Paulista (Unesp), 2010)
The best way to detect breast cancer is by screening mammography. The mammography equipments are dedicated and require a rigorous quality control in order to have a good quality image and to early detect this disease. The ...
