To rapidly assess the potential for damage of an earthquake for purposes of earthquake early warning in Taiwan, we used the peak displacement and velocity amplitudes of the first 3 sec of the P wave. The vertical-component records, highpass filtered at 0.075 Hz, are used. We found that the peak initial-displacement amplitude (Pd) correlates well with the peak ground-motion displacement (PGD) an...

BACKGROUND Cardiovascular magnetic resonance (CMR) is commonly used in patients with suspected arrhythmogenic right ventricular cardiomyopathy (ARVC) based on ECG, echocardiogram and Holter. However, various diseases may present with clinical characteristics resembling ARVC causing diagnostic dilemmas. The aim of this study was to explore the role of CMR in the differential diagnosis of patient...

Differential SAR interferometry with ERS data has a high potential for surface displacement mapping in the mm to m range. Such displacement information is of interest for the monitoring of phenomena as land subsidence, land slides, earthquakes, volcano swelling, and ice motion. In this contribution the maturity and operational readiness of the SAR interferometric technique are discussed, focusi...

The potential energy surface is an important determinant of a chemical reaction. Three ways of deducing non-trivial properties of such surfaces from the results of crystal structure analyses are discussed and illustrated with examples. (1) The mapping approach brings together structures of the same molecular fragment from different environments to outline reaction coordinates and vibrations. (2...

Molecular dynamics simulations, combined with umbrella sampling, is used to study how gramicidin A (gA) dimers dissociate in the lipid bilayer. The potential of mean force and intermolecular potential energy are computed as functions of the distance between center of masses of the two gA monomers in two directions of separation: parallel to the bilayer surface and parallel to the membrane norma...

The spring rates of a coiled helical spring under an axial force and an axially directed torque are derived by a consistent application of Castigliano’s second theorem, and it is shown that the coupling between the two loads may not always be neglected. The spring rate of an extensional spring is derived for the first time through the use of the displacement based principle of minimum total pot...
