This paper mainly concerns the study of a large class of variational systems governed by parametric generalized equations, which encompass variational and hemivariational inequalities, complementarity problems, first-order optimality conditions, and other optimization-related models important for optimization theory and applications. An efficient approach to these issues has been developed in o...

In 2 experiments, we used event-related brain potentials (ERPs) to examine the temporal dynamics of neural processes related to adjustments of cognitive control following errors in the counting Stroop task. The ERPs elicited by errors revealed the error-related negativity (ERN) and error positivity consistent with a large body of literature. In addition, errors were associated with a frontal sl...

CONTEXT Whether virtual rehabilitation is beneficial has not been determined. OBJECTIVE To investigate the psychological benefits of virtual reality in rehabilitation. DESIGN An experimental group underwent therapy with a virtual-reality-based exercise bike, and a control group underwent the therapy without virtual-reality equipment. SETTING Hospital laboratory. PATIENTS 30 patients suf...

In this paper we study nonlinear programming problems with equality, inequality, and abstract constraints where some of the functions are Fréchet differentiable at the optimal solution, some of the functions are Lipschitz near the optimal solution, and the abstract constraint set may be nonconvex. We derive Fritz John type and Karush–Kuhn–Tucker (KKT) type first order necessary optimality condi...

OBJECTIVE Clinical observations suggest that negative affects such as helplessness/hopelessness (HE/HO) may induce autonomic duration; affects were assessed for every move after reconstruction of the games. In all games compiled, 18 situation of intense confidence/optimism and 20 of intense helplessness/hopelessness were observed. RESULTS Intense affects of HE/HO were associated with decreasi...

Abstract Humble leadership can be described as a positive psychological feature that allows leaders to admit their limitations, open new ideas, and give voice others while also recognizing merits. The present study ( n = 268 participants) explored the persuasive effects of female politician communicating humble stance by considering role emotional displays at play (joy, calmness, sadness, anger...

The purpose of this case study is to describe the chiropractic care of a 4-year-old male patient with agenesis of the corpus callosum. Methods: Chiropractic care plan consisted of weekly appointments with the inclusion of at-home exercises coupled with academic intervention of physical and occupational therapies and assistive gait devices. Functional changes were monitored via objective clinic ...

Our aim in this paper is to refine the well-known necessary optimality conditions for the general Bolza problem under a calmness assumption. We prove Lagrangian and Hamiltonian necessary optimality conditions without standard convexity assumptions. Our refinements consist in the utilization of a small subdifferential and in the presence of the maximum condition without convexity assumption on t...

In this paper, we present a comparative overview of 9 studies on perceptual quality dimensions of synthetic speech. Different subjective assessment techniques have been used to evaluate the text-to-speech (TTS) stimuli in each of these tests: in a semantic differential, the test participants rate every stimulus on a given set of rating scales, while in a paired comparison test, the subjects rat...

In order to determine the influence of noise sensitivity on sleep, subjective sleep quality, annoyance, and performance after nocturnal exposure to traffic noise, 12 women and 12 men (age range, 19-28 years) were observed during four consecutive nights over a three weeks period. After a habituation night, the participants were exposed with weekly permuted changes to air, rail and road traffic n...
