PURPOSE This in vitro study compared the effect of five different techniques on the surface roughness of feldspathic porcelain. MATERIALS AND METHODS 100 feldspathic porcelain disk samples mounted in acrylic resin blocks were divided into five groups (n=20) according to type of surface treatment: I, hydrofluoric acid (HFA); II, Deglazed surface porcelain treated with Neodymium:yttrium- alumin...

A theme of recent side-channel research has been the quest for distinguishers which remain e ective even when few assumptions can be made about the underlying distribution of the measured leakage traces. The Kolmogorov-Smirnov (KS) test is a well known nonparametric method for distinguishing between distributions, and, as such, a perfect candidate and an interesting competitor to the (already m...

The practice of capture-recapture to estimate the diversity is well known to many animal groups, however this practice in the larval phase of anuran amphibians is incipient. We aimed at evaluating the Lincoln estimator, Venn diagram and Bayes theorem in the inference of population size of a larval phase anurocenose from lotic environment. The adherence of results was evaluated using the Kolmogo...

Objective: To analyze retrospectively the surgical outcomes of a group of patients with bone metastases and multiple myeloma in the spine, which underwent neurological decompression and arthrodesis using pedicle screws, by isolated posterior approach, to check whether the operated patients present clinical improvement regarding the pain and neurological deficit compared to the preoperative peri...

Large mixing induced νμ ↔ νe transitions can explain the deficit in the flux of the low energy atmospheric νμ whereas the solar neutrino deficit can be simultaneously explained through MSW transitions νe → ντ . A combined analysis of both these effects is presented. The large νe − νμ mixing affects the MSW transition between νe and ντ significantly. As a consequence, a large region of parameter...

Taking the solar and the atmospheric neutrino experiments into account we discuss the lepton flavor violating processes, such as τ → μγ or μ → eγ, in the minimal supersymmetric standard model with right-handed neutrinos (MSSMRN) and the supersymmetric SU(5) GUT with righthanded neutrinos [SU(5)RN]. The predicted branching ratio of μ → eγ in the MSSMRN with the Mikheyev-Smirnov-Wolfenstein (MSW)...
