Molecular activation in cellular microdomains is usually characterized by a forward binding rate, which is the reciprocal of the arrival time of a ligand to a key target. Upon chemical interactions or conformational changes, a Brownian ligand may randomly switch between different states, and when target activation is possible in a specific state only, switching can significantly alter the activ...

Intrinsic Josephson Junctions (IJJs) are the subject of much of research due to their potential applications as high frequency oscillators and detectors in the THz range. A number of previous studies use a single junction model to explain their observations, as no fully agreed model for coupled IJJs exists. The influence of one or more IJJs in the voltage state on other junctions in the IJJ arr...

In this study, two-state Markov switching multinomial logit models are proposed for statistical modeling of accident-injury severities. These models assume Markov switching over time between two unobserved states of roadway safety as a means of accounting for potential unobserved heterogeneity. The states are distinct in the sense that in different states accident-severity outcomes are generate...

It has been shown that max-plus linear systems are well suited for applications in synchronization and scheduling, such as the generation of train timetables, manufacturing, or traffic. In this paper we show that the same is true for multi-legged locomotion. In this framework, the max-plus eigenvalue of the system matrix represents the total cycle time, whereas the max-plus eigenvector dictates...

The present paper describes a robust approach for abbreviating terms. First, in order to incorporate non-local information into abbreviation generation tasks, we present both implicit and explicit solutions: the latent variable model, or alternatively, the label encoding approach with global information. Although the two approaches compete with one another, we demonstrate that these approaches ...

When the external magnetic field applied to a ferromagnetically coupled atomic chain is reversed suddenly, the magnetization of the chain switches, due to the reversal of all the atomic magnetic moments in the chain. The quantum processes underlying the magnetization switching and the time required for the switching are analyzed for model magnetic chains adsorbed on a surface at 0 K. The sudden...

Switching dynamics among saddles in a network of nonlinear oscillators can be exploited for information encoding and processing (hence computing), but stable attractors in the system can terminate the switching behavior. An effective control strategy is presented to sustain switching dynamics in networks of pulse-coupled oscillators. The support for the switching behavior is a set of saddles, o...

A method is proposed to infer Lyapunov and asymptotic stability properties for switching systems, under arbitrary continuous-state feedback. Continuous-time systems which are dissipative in the multiple-storage function sense are considered. A partition of the state space, induced by the cross-supply rates and the feedback function, is used to derive conditions for stability. It is argued that ...

Polarization switching of light in a degenerate two-level medium, known as the Λ-configuration, is described. The polarization dynamics of light pulses is investigated by means of the inverse-scattering transform. The mathematical formalism of the inverse-scattering transform that takes into account the initial fluctuations of the medium polarization components corresponding to atomic transitio...
