Cooling Down Lévy Flights
Let L(t) be a Lévy flights process with a stability index α ∈ (0, 2), and U be an external multiwell potential. A jump-diffusion Z satisfying a stochastic differential equation dZ(t) = −U ′(Z(t−))dt+ σ(t)dL(t) describes an evolution of a Lévy particle of an ‘instant temperature’ σ(t) in an external force field. The temperature is supposed to decrease polynomially fast, i.e. σ(t) ≈ t for some θ ...
متن کاملCooling Down Hot Air A Global
The Kyoto Protocol marks a break-through in global warming mitigation policies as it sets legally binding emissions targets for major emitting regions. However, realisation of the Protocol depends on the clarification of several issues one of which is the permissible scope of international emissions trading between signatory countries. Unrestricted trade produces hot air when signatory countrie...
متن کاملCooling-induced SUMOylation of EXOSC10 down-regulates ribosome biogenesis.
The RNA exosome is essential for 3' processing of functional RNA species and degradation of aberrant RNAs in eukaryotic cells. Recent reports have defined the substrates of the exosome catalytic domains and solved the multimeric structure of the exosome complex. However, regulation of exosome activity remains poorly characterized, especially in response to physiological stress. Following the ob...
متن کاملCooling of Hybrid Stars with Spin Down Compression
We study the cooling of hybrid stars coupling with spin-down. Due to the spindown of hybrid stars, the interior density continuously increases, different neutrino reactions may be triggered(from the modified Urca process to the quark and nucleon direct Urca process) at different stages of evolution. We calculate the rate of neutrino emissivity of different reactions and simulate the cooling cur...
متن کاملRotational Effects of Nanoparticles for Cooling down Ultracold Neutrons
Due to quantum coherence, nanoparticles have very large cross sections when scattering with very cold or Ultracold Neutrons (UCN). By calculating the scattering cross section quantum mechanically at first, then treating the nanoparticles as classical objects when including the rotational effects, we can derive the associated energy transfer. We find that rotational effects could play an importa...
