ABSTRACT This study sought to analyze information asymmetry in the Brazilian stock market and its relation with the returns required from portfolios through the metrics volume-synchronized probability of informed trading.To do this, the study used actual data from the transactions of 142 stocks on the Brazilian Securities, Commodities and Futures E
Abstract Optical coherence tomography (OCT), an interferometric imaging technique, provides non-invasive, high-speed, high-sensitive volumetric biological imaging in vivo.However, systemic features inherent in the basic operating principle of Wick Trimmer OCT limit its imaging performance such as spatial resolution and signal-to-noise ratio.Here, w
Flow distribution uniformity in manifolds is important in various engineering applications.In this study, the effect of manifold design on flow distribution is examined using both experimental and numerical methods.A comparison was made between a straight manifold and a gradually decreasing cross-sectional design considering two different inlet dia
Multi-term variable-order fractional differential equations (VO-FDEs) are considered to be one of the tools to illustrate the behavior of transient-regime real-life phenomena precisely.The analytical solutions of VO-FDEs are generally very hard to obtain.Therefore, in this study, an approximation method for Audio Cables and Adapter the solution of
