Freezing Transition in the Barrier Crossing Rate of a Diffusing Particle [PDF]
Physical Review Letters, 2020 We study the decay rate $θ(a)$ that characterizes the late time exponential decay of the first-passage probability density $F_a(t|0) \sim e^{-θ(a)\, t}$ of a diffusing particle in a one dimensional confining potential $U(x)$, starting from the origin, to a position located at $a>0$.

Crossing rate and distance in upland rice [PDF]
Bragantia, 2005 Rice (Oryza sativa L.) is an autogamous species that shows natural crossing rates of up to 3%, where the variations are influenced by genotypes and environments. The present work aimed to evaluate the rates and distances of natural crossing between the upland rice cultivars Guarani and IAC 201.

On the Level Crossing Rate of Fluid Antenna Systems
2022 IEEE 23rd International Workshop on Signal Processing Advances in Wireless Communication (SPAWC), 2022 Multiple-input multiple-output (MIMO) technology has significantly impacted wireless communication, by providing extraordinary performance gains. However, a minimum inter-antenna space constraint in MIMO systems does not allow its integration in devices with limited space.

Multilevel crossing rates for automated signal classification [PDF]
ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005 An investigation was made of multilevel crossing rates as a means of time series analysis of random signals. Pattern recognition techniques based on the Mahalanobis distance were implemented as a means of evaluating the discriminating power of level crossings.

Bounds and Prices of Currency Cross-Rate Options [PDF]
SSRN Electronic Journal, 2007 Abstract This paper derives the pricing bounds of a currency cross-rate option using the option prices of two related dollar rates via a copula theory and presents the analytical properties of the bounds under the Gaussian framework. Our option pricing bounds are useful, because (1) they are general in the sense that they do not rely on the ...

Option prices and risk‐neutral densities for currency cross rates [PDF]
Journal of Futures Markets, 2009 AbstractThe theoretical relationship between the risk‐neutral density (RND) of the euro/ pound cross rate and the bivariate RND of the dollar/euro and the dollar/pound rates is derived; the required bivariate RND is defined by the dollar‐rate marginal RNDs and a copula function.

Intermolecular Hydrogen Bonding Controlled Intersystem Crossing Rates of Benzophenone [PDF]
The Journal of Physical Chemistry Letters, 2018 Solvation plays a critical role in various physicochemical and biological processes. Here, the rate of intersystem crossing (ISC) of benzophenone from its S1(nπ*) state to its triplet manifold of states is shown to be modified by hydrogen-bonding interactions with protic solvent molecules. We selectively photoexcite benzophenone with its carbonyl group

Envelopes of Vector Random Processes and Their Crossing Rates
The Annals of Probability, 1979 Vector-valued random processes, $\mathbf{X}(t)$, can be "enveloped" by set-valued random processes, $\mathscr{S}(t)$, to which they belong with probability 1 during any finite length of time. When applied to scalar processes, the set-definition of envelope includes and is richer than the familiar point-definitions. Several random set-envelope processes
