We propose to measure the importance of spin-orbit couplings (SOCs) in the nonadiabatic molecular quantum dynamics rigorously with quantum fidelity. To make the criterion practical, quantum fidelity is estimated efficiently with the multiple-surface dephasing representation (MSDR). The MSDR is a semiclassical method that includes nuclear quantum effects through interference of mixed quantum-cla...

The early design phase of launch vehicles often involves low fidelity models that are characterized by a high level modeling uncertainties. These uncertainties have to be propagated into the whole process in order ensure robustness found vehicle architecture. Launch trajectory optimization induces large computational cost for uncertainty propagation using nested loop approach (outer and inner o...

We describe how long-term solar system orbit integration could be implemented on a parallel computer. The interesting feature of our algorithm is that each processor is assigned not to a planet or a pair of planets but to a time-interval. Thus, the 1st week, 2nd week,: : : , 1000th week of an orbit are computed concurrently. The problem of matching the input to the (n+ 1)-st processor with the ...

The genetic control of propagation effects and the impact of stock-plant age and source was examined in 9 month-old Pinus radiata cuttings. The cuttings investigated were propagated from stock-plants aged between 2 and 5 years, and microcuttings propagated from 12 week old stock-plants. The design included 20 families, with seven clones per family and an average of seven ramets per clone. Five ...

Orbit uncertainty propagation usually requires linearized propagation models [1–3] or full nonlinear Monte Carlo simulations [4]. The linear assumption simplifies the problem, but fails to characterize trajectory statistics when the system is highly nonlinear or when mapped over a long time period. On the other hand, Monte Carlo simulations provide true trajectory statistics, but are computatio...

myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary glands of the oral cavity. it is known to be a rare entity occurring at unusual locations, which makes it difficult to diagnose. such a rare case of myoepithelioma in salivary glands present at an unusual location around the left orbit is presented here.

The effect of current flow on the transmembrane action potential of single fibers of ventricular muscle has been examined. Pulses of repolarizing current applied during the plateau of the action potential displace membrane potential much more than do pulses of depolarizing current. The application of sufficiently strong pulses of repolarizing current initiates sustained repolarization which per...
