Relatively high deposition of nitrogen (N) in the northeastern United States has caused concern because sites could become N saturated. In the past, mass-balance studies have been used to monitor the N status of sites and to investigate the impact of increased N deposition. Typically, these efforts have focused on dissolved inorganic forms of N (DIN = NH4-N + NO3-N) and have largely ignored dis...

Abstract Scientific investigation in the cultural heritage field is generally aimed at characterization of constituent materials and conservation status artworks. Since 1990s, reflectance spectral imaging proved able to map pigments, reveal hidden details evaluate presence restorations paintings. Over past two decades, hyperspectral has further improved our understanding paints its changes time...

The Mumford-Shah model has been one of the most powerful models in image segmentation and denoising. The optimization of the multiphase Mumford-Shah energy functional has been performed using level sets methods that optimize the Mumford-Shah energy by evolving the level sets via the gradient descent. These methods are very slow and prone to getting stuck in local optima due to the use of the gr...

A diverse body of research has demonstrated that people update their beliefs to a greater extent when receiving good news compared to bad news. Recently, a paper by Shah et al. claimed that this asymmetry does not exist. Here we carefully examine the experiments and simulations described in Shah et al. and follow their analytic approach on our data sets. After correcting for confounds we identi...

Sistemele de monitorizare pe scară largă permit colectarea eficientă a datelor din câmp la rezoluții temporale și spațiale ridicate. Un exemplu relevant îl constituie aplicarea acestor sisteme în domeniul monitorizării infrastructurilor de transport al produselor petroliere pentru prevenirea scurgerilor și a accesului neautorizat, ce pot cauza daune de mediu și economice semnificative. Lucrarea...
