A striking feature of the studies that have addressed the measurement of the amygdala is the wide range of volumes encountered, with reports of volumes ranging from 1 to almost 4 cm(3). Another striking feature is the number of discrepancies in the landmarks adopted for manual tracing in magnetic resonance imaging (MRI). The goal of our study was to assess(More)
OBJECTIVES We measured the volumes of the amygdala to test the hypothesis that the reduction of amygdalar volume may be associated with psychiatric symptoms in Alzheimer's disease. MATERIALS AND METHODS Twenty-seven patients underwent neuropsychological investigation including the assessment of general clinical severity by the Mini-Mental State(More)
OBJECTIVE Based on the clinical observation that patients suffering from narcolepsy with cataplexy (NC) have cataplectic attacks when they experience positive emotions, it is therefore hypothesised that the abnormal processing of external emotional input through the limbic system, or motor dysregulation induced by emotions, takes place during these(More)
BACKGROUND For comparing of the pathological and normal healthy state it is essential to obtain sufficient amount of the volumetric data. Nevertheless most of the publicized works use only few healthy controls opposite to the patients for the measuring of the basal ganglia volume. Further essential condition is to take into account the effect of age to the(More)
In this paper, we present two iterative algorithms for approximating the absorption spectrum of molecules within the linear response of time-dependent density functional theory (TDDFT) framework. These methods do not attempt to compute eigenvalues or eigenvectors of the linear response matrix. They are designed to approximate the absorption spectrum as a(More)
The biennial plant Gentianella bohemica is a subendemic of the Bohemian Massif, where it occurs in seminatural grasslands. It has become rare in recent decades as a result of profound changes in land use. Using amplified fragment length polymorphisms (AFLP) fingerprint data, we investigated the genetic structure within and among populations of G. bohemica(More)
We present an algorithm for reducing the computational work involved in coupled-cluster (CC) calculations by sparsifying the amplitude correction within a CC amplitude update procedure. We provide a theoretical justification for this approach, which is based on the convergence theory of inexact Newton iterations. We demonstrate by numerical examples that,(More)
PREMISE OF THE STUDY Polymorphic microsatellite loci were developed and used to genotype individuals of Gentianella praecox subsp. bohemica (Gentianaceae), a highly protected taxon in Europe, to study the genetic structure of the remaining populations. METHODS AND RESULTS Thirty-eight primer pairs were successfully amplified; of these, 12 polymorphic(More)
