First results of numerical simulations are presented which compute the dynamical evolution of a neutron star with a mass slightly below the minimum stable mass by means of a new implicit (general relativistic) hydrodynamic code. We show that such a star first undergoes a phase of quasi-static expansion, caused by slow nuclear β-decays, lasting for about 20 seconds, but then explodes violently. ...

We discuss the feasibility of using the detection of electron antineutrinos produced in fission to monitor the time dependence of the Plutonium content of nuclear power reactors and large (> 1 MWatt) research reactors. If practical such a scheme would allow worldwide, automated monitoring of reactors and, thereby, the detection of proliferation attempts. Although this idea shows some promise, w...

The interactions between mitochondria and nucleus substantially influence plant development, stress response and morphological features. The prominent example of a mitochondrial-nuclear interaction is cytoplasmic male sterility (CMS), when plants produce aborted anthers or inviable pollen. The genes responsible for CMS are located in mitochondrial genome, but their expression is controlled by n...

Abstract Core-collapse simulations of massive stars are performed using the equation state (EOS) based on microscopic variational calculation with realistic nuclear forces. Progenitor models initial masses 15, 9.6, and 30 $M$? adopted as examples an ordinary core-collapse supernova a shock stall, low-mass successful explosion, black hole formation, respectively. Moreover, neutrinos emitted from...

Ultrashort x-ray pulses from free-electron lasers can efficiently charge up and trigger the full fragmentation of molecules. By coincident detection to five ions resulting rapid Coulomb explosion highly charged iodomethane, we show that three-dimensional equilibrium geometry this prototypical polyatomic system be determined measured ion momenta with help a buildup model. Supported by simulation...
