This work presents a novel C-C distance dependent force field which is successful in selecting native structures from an ensemble of high resolution near-native conformers. An enhanced and diverse protein set, along with an improved decoy generation technique, contributes to the effectiveness of this potential. High quality decoys (structures with low root mean square deviation with respect to ...

In conventional nitride-based light emitting diodes, huge internal electric fields lead to a reduced overlap of electron and hole wave functions in the active GaInN quantumwells as a consequence of the piezoelectricity of these polar materials. In order to minimize these internal fields while still maintaining the well-established c-direction as main epitaxial growth direction for high-quality ...

Individual, strongly electroluminescent Ag(n) molecules (n = 2 approximately 8 atoms) have been electrically written within otherwise nonemissive silver oxide films. Exhibiting characteristic single-molecule behavior, these individual room-temperature molecules exhibit extreme electroluminescence enhancements (>10(4) vs. bulk and dc excitation on a per molecule basis) when excited with specific...

Recently, explicit real time dynamics has been studied in various systems. These quantum mechanical dynamics could provide new recipes in information processing. Here, we study quantum dynamics under time dependent external field. In particular, we compare the thermal and quantum fluctuation in the transverse Ising model. Moreover we study other types of quantum fluctuations, e.g. effects of th...

From the pulse length dependence of the absorption of intense ultrashort laser pulses focused inside fused silica, we reveal the role field-assisted collisional ionization plays in the multiphoton ionization process. This constitutes a cold avalanche ionization mechanism that persists at pulse lengths considered too short for a traditional avalanche.

The relativistic mean-field theory provides a framework in which the nuclear manybody problem is described as a self-consistent system of nucleons and mesons. In the mean-field approximation, the self-consistent time evolution of the nuclear system describes the dynamics of collective motion: double giant resonances, nuclear compressibility from monopole resonances, regular and chaotic dynamics...

When a neuron could be recorded stably for sufficient time we verified our hand-plotted estimates of receptive field location using an automated stimulus presentation/response collation system (see Supplementary Methods online). As illustrated by the examples shown in Supplementary Figure 1, the two methods of estimating receptive field location show a close correspondence. We measured the disc...
