Quasistates in a ring coupled to a reservoir and their relation to the Dicke effect [PDF]
We study the energy spectrum and the persistent current in an ideal one-dimensional mesoscopic ring coupled to an external fermionic reservoir. The contact between ring and reservoir is described by a tunneling operator, which causes an indirect coupling between different ring states via states in the reservoir. For strong coupling to the reservoir new

To enable versatile unconventional computing, a single SiOx threshold switching device is engineered to exhibit controllable dual‐mode oscillation. By modulating the input voltage, the device selectively provides stable full oscillation for oscillatory neural networks and stochastic probabilistic oscillation for probabilistic bits and true random ...

Revealing Two Operation Modes of Perovskite Light‐Emitting Diodes Through Overshoot Pulses
Short, high‐intensity overshoot pulses (OSPs) may be generated by perovskite light‐emitting diodes (PeLEDs) depending on electrical pump pulse parameters, offset and afterpulse voltages. OSPs reveal two PeLED operation modes: the recombination mode, favorable for the conventional EL but preventing OSPs, and the accumulation mode, enabling the formation

Numerical measure of strong stability and strong quasistability in the vector problem of integer linear programming [PDF]
In this paper we consider a vector integer programming problem with the linear partial criteria. Numerical evaluations of two types of stability of the Pareto set have been found.

Spectrum of quasistable states in a strong infrared field
The stability of highly excited hydrogen and helium atoms subject to an intense infrared laser field is studied, and similarities to the case of microwave driving are discussed.

Mining‐induced coal seam extraction causes deformation and fracturing of the overburden, leading to the development of fractures, which pose significant threats to mine safety, surface structures, and natural ecosystems. To address the challenge of quantitatively characterizing overburden fractures caused by coal seam mining, this study, taking the 12 ...

Clifford representatives via the uniform algebraic rank
Abstract In this paper, we introduce the uniform algebraic rank of a divisor class on a finite graph. We show that it lies between Caporaso's algebraic rank and the combinatorial rank of Baker and Norine. We prove the Riemann–Roch theorem for the uniform algebraic rank, and show that both the algebraic and the uniform algebraic rank are realized on ...

The deformation of concrete dams directly reflects their structural health and operational state, serving as a critical foundation for safety assessment and early risk warning. Accurately predicting dam deformation patterns is thus essential for ensuring long‐term structural safety and enabling scientific operation management.

On stability and quasi-stability of a vector lexicographic quadratic boolean programming problem
We consider a vector Boolean programming problem with the linear-quadratic partial criteria. Formulas of radiuses of two types of stability, necessary and sucient conditions of stability are found.

EEG microstates show different features in focal epilepsy and psychogenic nonepileptic seizures
Abstract Objective Electroencephalography (EEG) microstate analysis seeks to cluster the scalp's electric field into semistable topographical EEG activity maps at different time points. Our study aimed to investigate the features of EEG microstates in subjects with focal epilepsy and psychogenic nonepileptic seizures (PNES).
