The S(N)2 displacement of Cl(-) from 1,2-dichloroethane by acetate (CH(3)CO(2)(-)) in water and by the carboxylate of the active site aspartate in the haloalkane dehalogenase of Xanthobacter autothropicus have been compared by using molecular dynamics simulations. In aqueous solution, six families of contact-pair structures (I-VI) were identified, and their relative concentrations and dissociat...

Scientific evidence is equivocal on whether Social Anxiety Disorder (SAD) is characterized by a biased negative evaluation of (grouped) facial expressions, even though it is assumed that such a bias plays a crucial role in the maintenance of the disorder. To shed light on the underlying mechanisms of face evaluation in social anxiety, the eye movements of 22 highly socially anxious (SAs) and 21...

OBJECTIVES To evaluate maternal and neonatal effects of desflurane compared with the sevoflurane for general anesthesia for cesarean section. METHODS The study was conducted as a prospective randomized blind study between January 2003 to January 2004 at the Hacettepe University, Ankara, Turkey. One hundred and two American Society of Anesthesiologists (ASA) I patients aged between 20-35 at 37...

Individuals with obsessive-compulsive disorder (OCD) often experience intrusive thoughts. These intrusions may be due to biases in information processing mechanisms, including attention, memory, and learning. To examine this hypothesis, we presented a modified negative priming (NP) paradigm with idiographically selected words to 19 individuals with OCD (OCs) and 19 matched non-anxious control p...

We investigate the classical and quantum properties of a system of SU(N) non-Abelian Chern-Simons (NACS) particles. After a brief introduction to the subject of NACS particles, we first discuss about the symplectic structure of various SU(N) coadjoint orbits which are the reduced phase space of SU(N) internal degrees of freedom or isospins. A complete Dirac’s constraint analysis is carried out ...

In this work, we address the modeling and solution of mixed-integer linear multistage stochastic programming problems involving both endogenous and exogenous uncertain parameters. We first propose a composite scenario tree that captures both types of uncertainty, and we exploit its unique structure to derive new theoretical properties that can drastically reduce the number of non-anticipativity...

The Approach-Avoidance Task (AAT) was employed to indirectly investigate avoidance reactions to stimuli of potential social threat. Forty-three highly socially anxious individuals (HSAs) and 43 non-anxious controls (NACs) reacted to pictures of emotional facial expressions (angry, neutral, or smiling) or to control pictures (puzzles) by pulling a joystick towards themselves (approach) versus pu...

We report on the creation of ultracold gases bosonic Feshbach molecules NaCs. The are associated from overlapping Na and Cs using a resonance at 864.12(5)G. characterize bound-state spectroscopy, in conjunction with coupled-channel calculation. By varying temperature atom numbers initial atomic mixtures, we demonstrate association NaCs over wide dynamic range molecule temperatures, reaching 70 ...

The human immune system consists of a large number of T cells capable of recognizing and responding to antigens derived from various sources. The development of peptide-major histocompatibility (p/MHC) tetrameric complexes has enabled the direct detection of these antigen-specific T cells. With the goal of increasing throughput and multiplexing of T cell detection, protein microarrays spotted w...
