Improvement of gross theory of beta-decay for application to nuclear data
EPJ Web of Conferences, 2017 A theoretical study of β decay and delayed neutron has been carried out with a global β-decay model, the gross theory. The gross theory is based on a consideration of the sum rule of the β-strength function, and gives reasonable results of β-decay rates ...

Asymptotic bound on slow-roll parameter in stringy quintessence model
Nuclear Physics BWe study the late time behavior of the scalar part of the volume modulus and the dilaton in stringy quintessence model, focusing on their contributions to the Hubble slow-roll parameter ϵ which directly measures the deviation of the spacetime geometry ...

Axion landscape and natural inflation
Physics Letters B, 2015 Multiple axions form a landscape in the presence of various shift symmetry breaking terms. Eternal inflation populates the axion landscape, continuously creating new universes by bubble nucleation.

Peccei-Quinn inflation at the pole and axion kinetic misalignment
Journal of High Energy PhysicsWe propose a minimal extension of the Standard Model with the Peccei-Quinn (PQ) scalar field and explain the relic density of the QCD axion through the kinetic misalignment with a relatively small axion decay constant. To this purpose, we consider a slow-

Validation of a roll decay test of an offshore installation vessel using openfoam
, 2019 In this work, the offshore heavy lift DP2 jack-up vessel Innovation from the DEME group is studied using the Computational Fluid Dynamics (CFD) toolbox OpenFOAM. The two-phase Navier-Stokes fluid solver is coupled with a motion solver using a partitioned fluid-structure interaction algorithm.
