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

Heterogeneous expectations in the foreign exchange market : evidence from the daily Dollar/DM exchange rate [PDF]
, 2003 In this study a regime switching approach is applied to estimate the chartist and fundamentalist (c&f) exchange rate model originally proposed by Frankel and Froot (1986).

Level crossing rates of interference in cognitive radio networks [PDF]
IEEE Transactions on Wireless Communications, 2010 The future deployment of cognitive radios is critically dependent on the fact that the incumbent primary user system must remain as oblivious as possible to their presence. This in turn heavily relies on the fluctuations of the interfering cognitive radio signals. In this letter we compute the level crossing rates of the cumulative interference created

Cytoskeletal remodeling slows cross‐bridge cycling and ATP hydrolysis rates in airway smooth muscle
Physiological Reports, 2020 During isometric activation of airway smooth muscle (ASM), cross‐bridge cycling and ATP hydrolysis rates decline across time even though isometric force is sustained.

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.

What aspects of primary care predict emergency admission rates? A cross sectional study
BMC Health Services Research, 2013 Background From 2004 to 2009 there was almost a 12% rise in emergency admissions in England. This can be explained partly by an aging population and other socio-demographic characteristics, but much cannot be explained by these factors.

National Variation in Caesarean Section Rates: A Cross Sectional Study in Ireland.
PLoS ONE, 2016 ObjectiveInternationally, caesarean section (CS) rates are rising. However, mean rates of CS across providers obscure extremes of CS provision. We aimed to quantify variation between all maternity units in Ireland.MethodsTwo national databases, the ...

The interest rate-exchange rate nexus in China: A DCCA cross-correlation coefficient with sliding window approach [PDF]
Economic Horizons, 2023 This study aims to investigate the dynamics of the interest rates and exchange rates during the pandemic-induced crisis in the Chinese economy. In the study, rolling window detrended cross-correlation analysis (DCCA) was used.

Efficient schemes to compute diffusive barrier crossing rates [PDF]
Molecular Physics, 1997 The formulation of the classical barrier-crossing problem is reviewed in the context of numerical simulations, with the focus on barrier crossing problems where the reaction coordinate depends in a non-trivial way on the Cartesian coordinates of many particles. Often it is convenient to measure the barrier height using constrained dynamics.
