Coherence and quasistable states in a strong infrared field
Physical Review A, 2016 We study the quasistability of UV-pulse-train-excited H atoms in a strong infrared (IR) laser as a function of the phase delay of the UV pulse train relative to the IR laser. The UV pulse train contains two frequency components. When the two components have frequencies separated by two IR photons, the population of surviving electrons is modulated by ...

Geoarchaeology, Volume 39, Issue 2, Page 143-167, March/April 2024.Abstract In geoarchaeological studies, there is an issue with distinguishing between natural and anthropogenic signals in pedological paleoarchives. With the pedostratigraphy of the Upper Paleolithic site of Kostenki 14, this issue is reflected by problems with the determination of features of pedogenic and pyrogenic processes. This issue was addressed

On quasi-stability of the vector Boolean problem of minimizing absolute deviations of linear functions from zero [PDF]
Computer Science Journal of Moldova, 2006 We consider a multi-criterion Boolean programming problem with partial criteria of the kind MIN MODUL of linear functions. We investigate such type of stability which can be understood as a discrete analogue of the Hausdorff lower semi-continuity.

Influence of Cobalt Doping on the Photogenerated Holes in ZnO Nanoparticles
physica status solidi (RRL) – Rapid Research Letters, Volume 18, Issue 3, March 2024.Doping ZnO nanoparticles with cobalt ions results in the killing of the core‐defect signal (right panel), which in turn inhibits the light‐induced hole releasing implied in methyl radical generation (left panel). The efficient cobalt doping of zinc oxide nanoparticles grown by chemical method, with Co2+ substituting the Zn2+ cations, is proved by ...

Advanced Intelligent Systems, Volume 6, Issue 1, January 2024.A deep imitation learning structure is proposed for optimal trajectory planning of an unstable dynamic system. Given the system's initial conditions, the neural networks (NNs) imitate the iterative linear quadratic regulator to generate near‐optimal trajectories. Leveraging on NN gradients, optimizing the system's initial conditions, avoiding obstacles,

A Torelli theorem for graphs via quasistable divisors
Forum of Mathematics, SigmaAbstractThe Torelli theorem establishes that the Jacobian of a smooth projective curve, together with the polarization provided by the theta divisor, fully characterizes the curve. In the case of nodal curves, there exists a concept known as fine compactified Jacobian.
