OBJECTIVE Driving activity requires major involvement of executive functions. The main objective of our study was to determine whether mental flexibility and the updating of information in working memory are affected in drivers with mild to moderate Parkinson's disease (PD). METHODS The study included 25 patients, aged 58-76, with mild to moderate PD and 25 healthy controls matched for age, s...

In this paper, we consider the problem of recovering a sparse vector from noisy measurement data. Traditionally, it is formulated as a penalized least-squares problem with an `1 penalty. Recent studies show that nonconvex penalties, e.g., `0 and bridge, allow more effective sparse recovery. We develop an algorithm of primal dual active set type for a class of nonconvex sparsity-promoting penalt...

Global warming has become a controversial public policy issue in spite of broad scientific consensus that it is real and that human activity is a contributing factor. It is likely that public consensus is also needed to support policies that might counteract it. It is therefore important to understand how people form and update their beliefs about climate change. Using unique survey data on bel...

Justification for updating the guideline for CKD Definition, Evaluation, Classification, and Stratification from an international perspective In 2002, the US-based Kidney Disease Outcomes Quality Initiative (KDOQI) group published a guideline on definition, classification and evaluation of chronic kidney disease (CKD). The guideline proposed uniform definitions of CKD together with a staging sy...

In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...
