We introduce a new multigrid method to study the lattice statics model arising from nanoindentation.A constrained Cauchy-Born elasticity model is used as the coarse-grid *** method accelerates the relaxation process and considerably reduces the computational *** particular,it saves quite a bit when dislocations nucleate and move,as demonstrated by the simulation results.

Low-spin states of neutron-rich 84,86,88Ge were measured by in-flight γ-ray spectroscopy at 270 MeV/u at the RIKEN-RIBF facility. The exotic beams have been produced by primary 238U in-flight fission reactions and impinged on the MINOS device. MINOS combines a 10-cm long LH2 target with a Time Projection Chamber (TPC) to reconstruct the reaction vertices. The reactions were selected by the BigRIPS and the ZeroDegree spectrometers for the incoming and outgoing channels, respectively. Emitted γ radiation was detected by the NaI-array DALI2. De-excitations from the , , and states of 84,86Ge and and states of 88Ge were observed. The data are compared to state-of-the-art shell model and beyond-mean-field calculations. Furthermore, a candidate for a state of 86Ge was identified. This state plays a key role in the discussion of ground-state triaxiality of 86Ge, along with other features of the low-energy level scheme. This work was published in [1].

This is an exciting time for the study of r-process nucleosynthesis. Recently, a neutron star merger GW170817 was observed in extraordinary detail with gravitational waves and electromagnetic radiation from radio to γ rays. The very red color of the associated kilonova suggests that neutron star mergers are an important r-process site. Astrophysical simulations of neutron star mergers and core collapse supernovae are making rapid progress. Detection of both, electron neutrinos and antineutrinos from the next galactic supernova will constrain the composition of neutrino-driven winds and provide unique nucleosynthesis information. Finally FRIB and other rare-isotope beam facilities will soon have dramatic new capabilities to synthesize many neutron-rich nuclei that are involved in the r-process. The new capabilities can significantly improve our understanding of the r-process and likely resolve one of the main outstanding problems in classical nuclear astrophysics However, to make best use of the new experimental capabilities and to fully interpret the results, a great deal of infrastructure is needed in many related areas of astrophysics, astronomy, and nuclear theory. We will place these experiments in context by discussing astrophysical simulations and observations of r-process sites, observations of stellar abundances, galactic chemical evolution, and nuclear theory for the structure and reactions of very neutron-rich nuclei. This review paper was initiated at a three-week International Collaborations in Nuclear Theory program in June 2016 where we explored promising r-process experiments and discussed their likely impact, and their astrophysical, astronomical, and nuclear theory context.

In Wu Fuzzy Systems and mathematics 3:94–99, 2012, the author introduced concepts of α-remote neighborhood mapping and α-quasi uniform, and obtained many good results in α-quasi uniform spaces. This chapter will further investigate properties of α-remote neighborhood mapping, and give some characterizations of α-quasi uniforms. Based on this, this chapter also introduces concept of α-P.Q. metric, and establishes the relations between α-quasi uniforms and α-P.Q. metrics. © Springer-Verlag Berlin Heidelberg 2014.

In this paper, concepts of ωα-Ti, (i = 0, 1, 2, 3, 4) sets are introduced in ωα-order preserving spaces and their characteristic properties are studied. They consist a new complete system of separation axiom, which is proved to be a good extension of both classical and fuzzy theories. Finally, their relationships are established and their differences are discussed by some exact examples. © Springer-Verlag Berlin Heidelberg 2014.
