The problem of escape of a Brownian particle in a cusp-shaped metastable potential is of special importance in nonadiabatic and weakly-adiabatic rate theory for electron transfer (ET) reactions. For the weakly-adiabatic reactions, the reaction follows an adiabaticity criterion in the presence of a sharp barrier. In contrast to the nonadiabatic case, the ET kinetics can be, however considerably ...

We determine the slip rate and pattern of interseismic coupling on the Main Himalayan Thrust along the entire Himalayan arc based on a compilation of geodetic, interferometric synthetic aperture radar, and microseismicity data. We show that convergence is perpendicular to the arc and increases eastwards from 13.3 ± 1.7 mm/yr to 21.2 ± 2.0 mm/yr. These rates are comparable to geological and geom...

Interaction of intense ultrashort (few-cycle) laser pulses with atoms and molecules leads to a highly nonlinear nonperturbative regime of electron dynamics and response. Ionized electrons are shown to be controlled by such pulses and the response is described by simple classical models of under and above barrier ionization followed by recollision with the parent ion or collision with neighborin...

Based on the Relativistic continuum Hartree-Bogoliubov (RCHB) theory, the pseudo-spin approximation in exotic nuclei is investigated in Zr and Sn isotopes from the proton drip line to the neutron drip line. The quality of the pseudo-spin approximation is shown to be connected with the competition between the centrifugal barrier (CB) and the pseudo-spin orbital potential (PSOP). The PSOP depends...

Thermal fatigue of Cu interconnects 60 nm thick and 5–15 lm wide was investigated by using alternating current to generate cycling temperature and strain/stress. The fatigue curves exhibit two regions, i.e. highand low-cycle regions, which correspond to low and high thermal strains, respectively. The high-cycle region is found to be controlled by an unusual thermal fatigue mechanism of damage b...

We propose a unified structural credit risk model incorporating insolvency, recovery and rollover risks. The firm finances itself mainly by issuing shortand long-term debt. Short-term debt can have either a discrete or a more realistic staggered tenor structure. We show that a unique threshold strategy (i.e., a bank run barrier) exists for short-term creditors to decide when to withdraw their f...

In this paper we show how to relate European call and put options on multiple assets to certain convex bodies called lift zonoids. Based on this, geometric properties can be translated into economic statements and vice versa. For instance, the European call-put parity corresponds to the central symmetry property, while the concept of dual markets can be explained by reflection with respect to a...

During the long-term operation, mallets of the forging hammers are exposed to thermal fatigue due to the cyclic temperature changes and impact loads. Taking into account very high price, and a risk of buying frequently the new parts, the necessity of their reparation becomes obvious. The forging hammer mallet (Figure 1), is primarily exposed to the impact compressive loads, and partially also t...

We have compared aging phenomena in the Fe0.5Mn0.5T iO3 Ising spin glass and in the CdCr1.7In0.3S4 Heisenberg-like spin glass by means of lowfrequency ac susceptibility measurements. At constant temperature, aging obeys the same ‘ωt scaling’ in both samples as in other systems. Investigating the effect of temperature variations, we find that the Ising sample exhibits rejuvenation and memory eff...
