Fibered holomorphic dynamics are skew-product transformations F (θ, z) = (θ + α, f θ (z)) over an irrational rotation, whose fibers are holomorphic functions. In this paper we study such a dynamics on a neighborhood of an invariant curve. We obtain some results analogous to the results in the non fibered case.
We consider the problem of the persistence of invariant curves for analytical fibered holomorphic transformations. We define a fibered rotation number associated to an invariant curve. We show that an invariant curve with a prescribed fibered rotation number persists under small perturbations on the dynamics provided that the pair of rotation numbers… (More)
A Pleural mass biopsy was performed showing an invasive thymoma. Computed tomography (CT) scan of the chest performed on admission revealed a left sided pleural mass, anterior mediastinal mass, lymphadenopathy and pericardial effusion. Pleural mass biopsy showed an invasive thy-moma. Due to her clinical presentation, a complete work-up was performed… (More)
BACKGROUND Patients with Tuberculosis (TB) are a vulnerable group for acquiring HIV infection. Therefore, countries with a concentrated HIV epidemic and high prevalence of TB should provide adequate information about HIV prevention to TB patients. METHODS We conducted a cross-sectional study to evaluate the level of knowledge on HIV prevention and… (More)
This work is a natural companion of , where the dynamics of cocycles of isometries of R ℓ over a minimal dynamics (semigroup action) is studied. While  is mostly devoted to the case in which the orbits of the fibered (skew) dynamics are bounded (a condition that turns out to be equivalent to the existence of a continuous invariant section), here we… (More)
—This paper presents the study of quasi-square waveforms in order to avoid the problem of acoustic resonances in lamps of high intensity discharge. The study consists in the analysis of the electric power waveform, mainly, the study of the effect of the power harmonics generated with the quasi square waveform over the arc discharge of the lamp. The… (More)
A 45-year-old male farmer was admitted with a 5-day history of fever, retrosternal chest pain, and mental obtundation. He lived in the highlands of Peru and had been in contact with the skin and viscera of deceased cattle for unknown reasons 8 days before initiation of symptoms. The physical examination showed fever, shock, a painless ulcerative skin lesion… (More)
Spatial autocorrelation is problematic for classical hierarchical cluster detection tests commonly used in multi-drug resistant tuberculosis (MDR-TB) analyses as considerable random error can occur. Therefore, when MDRTB clusters are spatially autocorrelated the assumption that the clusters are independently random is invalid. In this research, a product… (More)
