Context. 55 Cnc e is in a 0.73 day orbit transiting Sun-like star. It has been observed that the occultation depth of this super-Earth, with mass 8 M ? and radius 2 R , changes significantly over time at mid-infrared wavelengths. Observations Spitzer measured change its day-side brightness temperature 1200 K, possibly driven by volcanic activity, magnetic star-planet interaction, or presence ci...

Abstract We present high-resolution near-infrared spectra taken during eight transits of 55 Cancri e, a nearby low-density super-Earth with short orbital period (<18 hr). While this exoplanet’s bulk density indicates possible atmosphere, one has not been detected definitively. Our analysis relies on the Doppler cross-correlation technique, which takes advantage high spectral resolution and b...

Introduction: Cleft lip and palate is a congenital anomaly occurring in 3 in 1000 live birth. One the major concern in this patient is about cleft gap and its surgical problems. Several surgical and non-surgical procedures have been done to decrease this gap. They aimed to achieve the more esthetic results as well as feeding success. Nasoalveolar Molding (NAM) is a new method for reshaping nasa...

In traditional approaches business processes are executed on top of IT-based Workflow-Management Systems (WfMSs). However, when dealing with human-driven workflows, conventional WfMSs may turn out to be too restrictive. Especially, the only way to handle exceptions is to bypass the system. If users are forced to bypass WfMSs frequently, the system is more an obstacle than an asset. In order to ...

We propose a concrete procedure of a Σ-protocol proving knowledge that a set of witnesses satisfies a monotone predicate in the witness-indistinguishable manner. Inspired by the high-level work proposed by Cramer, Damg̊ard and Schoenmakers at CRYPTO ’94, we provide a concrete procedure by extending the so-called OR-proof.

Este estudo comparou quatro procedimentos de extração para a determinação simultânea das micotoxinas citrinina e ocratoxina A em amostras de arroz. Os procedimentos de Soares e Rodriguez-Amaya, Tanaka e os métodos de extração QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) e por ultrassom foram comparados em termos de geração de resíduos, limite de detecção, limite de quantificação e ...
