This paper focuses on the effect of mergers and acquisitions (M&As) announcements stocks Latin American banks their rivals between 2000 2019. We evaluate two impacts M&A announcements: cumulative abnormal returns (CAR) event-induced variance (EIV). use GARCH-based event-study method, finding that acquirers target have a statistically significant CAR targets are not affected by announcements. ob...

A multiscale approach to data rectification is proposed for data containing features with different time and frequency localization. Noisy data are decomposed into contributions at multiple scales and a Bayesian optimization problem is solved to rectify the wavelet coefficients at each scale. A linear dynamic model is used to constrain the optimization problem, which facilitates an error-in-var...

Situation awareness for vehicular safety and autonomy functions includes knowledge of the drivable area. This area is normally constrained between stationary road-side objects as guard-rails, curbs, ditches and vegetation. We consider these as extended objects modeled by polynomials along the road, and propose an algorithm to track each polynomial based on noisy range and bearing detections, ty...

In recent years, Mongolia has experienced recurrent epizootics of equine influenza virus (EIV) among its 2·1 million horses and multiple incursions of highly pathogenic avian influenza (HPAI) virus via migrating birds. No human EIV or HPAI infections have been reported. In 2009, 439 adults in Mongolia were enrolled in a population-based study of zoonotic influenza transmission. Enrollment sera ...

در این پژوهش، تغییرات زمانی تپ‌های لیزری 2CO TEA که از اتاقکی حاوی گاز 6SF با فشار mbar 150-10 عبور می‌کند، شاریدگی‌های انرژی و فشارهای گازی مختلف بررسی شده است. نشان داده است برای هر شاریدگی، قطع معینی وجود دارد قطع، میخه تپ به طور کامل حذف می‌شود، درحالی دنباله دربرگیرنده کسر قابل توجهی اولیه آن است، برجامی‌ماند. شواهد تجربی برآمده داده‌های بیناب‌سنجی FTIR، گسست چندفوتونی مولکول‌های را پاسخگو...

The Errors-in-Variables context is a challenging environment well known from many years that has seen an increasing amount of research and, consequently, of new results, only in relatively recent times. One of the appealing features of EIV models consists in their intrinsic capability of describing real processes and in relying only on limited sets of a–priori assumptions [24, 25]. These featur...

Although still in practice, the use of total least squares (TLS) in optical flow estimation is unreliable. TLS implicitly assumes that the error terms affecting the partial derivatives of the image intensities are independent. The usual methods for estimating the partial derivatives ensures that the errors are strongly correlated. Due to this correlation, an alternative method is required to tr...
