 Cascade dynamics of kaonic nitrogen atom (K-N) in a gaseous target was simulated using a simple model. In this model the radiative transitions, internal Auger, K-electron refilling, nuclear absorption, and kaon decay processes were included. The effect of the K-electron refilling process on some of quantities of cascade dynamics such as X-ray yields, the averaged K-electron shell number, fract...

Recent improvements to the Cascade-Exciton Model (CEM) of nuclear reactions are briefly described. They concern mainly the cascade stage of reactions and a better description of nuclei during the preequilibrium and evaporation stages of reactions. The development of the CEM concerning fission is given in a separate talk at this conference. The increased accuracy and predictive power of the CEM ...

During Drosophila eye development, a Ras cascade mediates the decision between neuronal and non-neuronal differentiation of the R7 photoreceptor precursor. Recent genetic and molecular studies have identified a set of protein kinases as components of the Ras cascade and nuclear targets of the cascade, including Yan, Pointed, Jun, and Phyllopod. The Ras cascade functions in other Drosophila sign...

Abstract A multi-phase transport (AMPT) model was constructed as a self-contained kinetic theory-based description of relativistic nuclear collisions it contains four main components: the fluctuating initial condition, parton cascade, hadronization, and hadron cascade. Here, we review developments after first public release AMPT source code in 2004 corresponding publication that described physi...

Hypertonic shock of Saccharomyces cerevisiae activates the Hog1p MAP kinase cascade. In contrast, protein kinase C (Pkc1p) and the "cell integrity" MAP kinase cascade are critical for the response to hypotonic shock. We observed that hypertonic shock transiently relocated many, but not all, nuclear and nucleolar proteins to the cytoplasm. We hypothesized that the relocation of nuclear proteins ...
