The ribonucleoside-derivs. serve for the synthesis of ribonucleic acids and comprise a triple substituted silyloxymethyl-group as a protection-group on the oxygen atom in 2'-position. The ribonucleoside-derivs. may be suitably protected on the nucleobase a ...
A first-principle molecular dynamics study on liquid GeSe2 yields structural properties in good agreement with detailed neutron scattering data. The short range order is accurately described by a variety of bonding configurations, in which regular tetrahed ...
A program's cache performance can be improved by changing the organization and layout of its data---even complex, pointer-based data structures. Previous techniques improved the cache performance of these structures by arranging distinct instances to incre ...
We show that the two-dimensional quantum confined Stark effect in a semiconductor quantum wire can display novel behaviour, i.e. wave function splitting and cascading. No analog to these phenomena can be found in bulk material or quantum wells. The consequ ...
The dipole moment of NO(B (2) Pi) was determined for the first time by high resolution laser-induced fluorescence molecular beam spectroscopy. Specific values obtained areas follows: mu(upsilon' = 3) = 0.293(3) D, mu(upsilon' = 4) = 0.276(9) D and mu(upsil ...
We present a comparative study of the structural properties of three different models for the Si(001)-SiO2 interface. The models are obtained by attaching different crystalline forms of SiO2, such as tridymite and beta-cristobalite, to Si(001). In the case ...
The full experimental evidence of fine structure in disordered superlattices is reported. The experimental results agree with the numerical predictions, thus indicating that this effect is related to residual coupling between adjacent identical wells in th ...
Rotationally resolved vibrational overtone spectra of several CH stretch bands of CF3H have been obtained using a combination of jet-cooling, infrared-optical double-resonance, and infrared laser assisted photofragment spectroscopy detection. The high sele ...
We describe a simple and robust method of creating an efficient large-angle adiabatic passage beamsplitter that does not require the light fields to be pulsed. We present simulations that show momentum splittings of 80 \hbar k, where more than 60% of the a ...
The direct piezoelectric effect in fine and coarse grain barium titanate ceramics is examined as a function of the external alternating and static pressure. It is found that domain wall vibrations contribute to the piezoelectric effect in both types of cer ...
