We present the simulation environment SIESTA (SIMULATION ENVIRONMENT FOR SEMICONDUCTOR TECHNOLOGY ANALYSIS) which provides facilities for time effective parallel distributed simulation. An optimization framework and its components which explore these features are described. Due to distributed simulation, the overall simulation time is drastically reduced by SIESTA. Optimizations are performed o...

Influence of Siesta in the Estimation of Blood Pressure Control in Patients With Hypertension To the Editor Banegas et al1 in their article have compared the measurements of blood pressure (BP) in the office and in ambulatory monitoring to assess the BP control in treated patients with hypertension in primary care centers. Ben-Dov and Busztyn,2 in their letter, have suggested that the influence...

We present the major features of a new implementation of a QM-MM method that uses the DFT code Siesta to treat the quantum mechanical subsystem and the AMBER force field to deal with the classical part. The computation of the electrostatic interaction has been completely revamped to treat periodic boundary conditions exactly, using a real-space grid that encompasses the whole system. Additional...

Mounting evidence for the role of sleep spindles in neuroplasticity has led to an increased interest in these non-rapid eye movement (NREM) sleep oscillations. It has been hypothesized that fast and slow spindles might play a different role in memory processing. Here, we present a new sleep spindle detection algorithm utilizing a continuous wavelet transform (CWT) and individual adjustment of s...

BACKGROUND Midday napping (siesta) is common in populations with low coronary mortality, but epidemiological studies have generated conflicting results. We have undertaken an analysis based on a sizable cohort with a high frequency of napping and information on potentially confounding variables including reported comorbidity, physical activity, and diet. METHODS Among participants in a genera...

Introduction: Circadian rhythms are genetically programmed traits coordinating behavior and metabolic responses with daily repeating environmental challenges, primarily with the solar day. Aging and circadian rhythms are interrelated: aging can modify the circadian rhythms, whereas age-changes of the rhythms contribute to the declined adaptability in aging. Material and Methods: Circadian rhyth...
