Molecular theory considering nuclear potential wells

Nuclear spin dynamics in parabolic quantum wells

We present a detailed analytical and numerical analysis of the nuclear spin dynamics in parabolic quantum wells. The shallow potential of parabolic quantum wells permits substantial modification of the electronic wave function in small electric fields. The nuclear spin relaxation via the hyperfine interaction depends on the electronic local density of states, therefore the local nuclear relaxat...

Considering Nuclear Compartmentalization in the Light of Nuclear Dynamics

Many proteins are concentrated in compartments within the nucleus. Chromatin is also compartmentalized at different nuclear sites. However, nuclear proteins have now been shown to be highly mobile. This review considers the formation and function of nuclear compartments in a situation in which proteins are rapidly moving through the nuclear volume.

Tunneling Ionization Rates from Arbitrary Potential Wells

We present a practical numerical technique for calculating tunneling ionization rates from arbitrary 1-D potential wells in the presence of a linear external potential by determining the widths of the resonances in the spectral density, ρ(E), adiabatically connected to the field-free bound states. While this technique applies to more general external potentials, we focus on the ionization of el...

Nuclear and cytoplasmic survivin: molecular mechanism, prognostic, and therapeutic potential.

Survivin's proposed dual role as an apoptosis inhibitor and a mitotic effector positioned it in the front line of cancer research. Notably, survivin is detected as a cytoplasmic and nuclear protein in cancer patients, which stimulated numerous studies to investigate and to speculate on the functional and prognostic significance of its dynamic localization. Recent evidence shows that the direct ...
