PVb prqpose a new nuclear reaction simulation, tenned the stochtzytic quantum cascade modeL which deals with proton-nucleus elastic scattering and multiple inelastic reactions. for the purpose qfmore precise dose estimation in particle cancer therapy. Based on stochastic guantization theor},, we describe the wave motion ofprotons using particie motion, i.e., IVbwtonian mechanics, and then incor...

Intranuclear cascade calculations and fluid dynamical predictions of the kinetic energy flow are compared for collisions of 4 0 ~ a + 4 0 ~ a and 2 3 8 ~ + 2 3 8 ~ . The aspect ratio, R13, as obtained from the global analysis, is independent of the bombarding energy for the intranuclear cascade model. Fluid dynamics, on the other hand, predicts a dramatic increase of R l j at medium energies Ei...

Nur77, an orphan nuclear receptor, plays a key role in apoptosis in T cells. In cancer cell lines, Nur77 can induce apoptosis through the intrinsic apoptotic pathway, but the mechanism by which Nur77 kills T cells remains controversial. In this study, we provide biochemical, pharmacological, and genetic evidence demonstrating that Nur77 induces apoptosis through the activation of the intrinsic ...

The status of some popular models to simulate hadronic and nuclear interactions at Cosmic Ray energies is reviewed. The models predict the rise of all the hadronic and nuclear cross sections with energy and a smooth (logarithmic) rise of average multiplicities, rapidity plateaus and average transverse momenta with the energy. Big differences are found between model predictions partly already at...

This paper describes a new technology for analyzing alarm cascades in nuclear power plant control rooms in real-time, thereby making operation safer and more productive. The technology is based on multilevel flow models and a root cause analysis algorithm developed at Lund University and GoalArt. It enables the solution of the alarm cascade problem for full-scale nuclear power plants. In the ne...

The molecular clock relies on a delayed negative feedback loop of transcriptional regulation to generate oscillating gene expression. Although the principal components of the clock are present in all circadian neurons, different neuronal clusters have varying effects on rhythmic behavior, suggesting that the clocks they house are differently regulated. Combining biochemical and genetic techniqu...

â liquefied natural gas (lng) is the most economical way of transporting natural gas (ng) over long distances. liquefaction of ng by using vapor compression refrigeration system requires high operating and capital cost. due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...

Heavy-ion collisions at ultrarelativistic energies provide extreme conditions of energy density and temperature to produce a deconfined state quarks gluons. Xenon (Xe), being deformed nucleus, further gives access the effect initial geometry on final particle production. This study focuses nuclear deformation hadron cascade-time production elliptic flow using multiphase transport (AMPT) model i...
