Plane correlations and hydrodynamic simulations of heavy ion collisionsDec 13 2013Jan 01 2014We use a nonlinear response formalism to describe the event plane correlations measured by the ATLAS collaboration. With one exception ($\left\langle \cos(2\Psi_2 - 6\Psi_3 + 4 \Psi_4) \right\rangle$), the event plane correlations are qualitatively reproduced ... More
Triangularity and Dipole Asymmetry in Heavy Ion CollisionsOct 09 2010We introduce a cumulant expansion to parameterize possible initial conditions in relativistic heavy ion collisions. We show that the cumulant expansion converges and that it can systematically reproduce the results of Glauber type initial conditions. ... More
Determining the evolutionary stage of the delta Scuti star HIP 80088 with asteroseismologySep 06 2018We have computed a grid of theoretical models to fit the twelve oscillation modes of HIP 80088 observed by K2. HIP 80088 is determined to be a pre-main sequence star, in which CN cycle has not arrived at the equilibrium state. Mass fractions of C12 and ... More
Impact parameter dependence of the scaling of anisotropic flows in intermediate energy HICSep 25 2013The scaling behaviors of anisotropic flows of light charged particles are studied for 25 \,MeV/nucleon $^{40}$Ca+$^{40}$Ca collisions at different impact parameters by the isospin-dependent quantum molecular dynamics model. The number of nucleons scaling ... More
Constraining the ejecta for the nonthermal emission from GW170817Apr 02 2018Jun 28 2018We consider a simple model for the nonthermal emission from GW170817, in which a quasi-spherical ejecta is released in the merger event, with the kinetic energy distributed over the momentum as $E(>\gamma\beta)\propto(\gamma\beta)^{-k}$. The ejecta drives ... More
Nonlinear elliptic equations with a singular perturbation on compact Lie groups and Homogeneous spacesMay 17 2012Feb 03 2013This paper is devoted to the study of a class of singular perturbation elliptic type problems on compact Lie groups or homogeneous spaces $\mathcal{M}$. By constructing a suitable Nash-Moser-type iteration scheme on compact Lie groups and homogeneous ... More
On extremal graphs with exactly one Steiner tree connecting any $k$ verticesJan 20 2013The problem of determining the largest number $f(n;\bar{\kappa}\leq \ell)$ of edges for graphs with $n$ vertices and maximal local connectivity at most $\ell$ was considered by Bollob\'{a}s. Li et al. studied the largest number $f(n;\bar{\kappa}_3\leq2)$ ... More
Let's Play Mahjong!Mar 08 2019Mahjong is a very popular tile-based game commonly played by four players. Each player begins with a hand of 13 tiles and, in turn, players draw and discard (i.e., change) tiles until they complete a legal hand using a 14th tile. In this paper, we initiate ... More
A Hopf-bifurcation theorem for the critically dissipative quasi-geostrophic equationMay 17 2012Apr 11 2014This paper is devoted to the study of the dynamical behavior of the critically dissipative quasi-geostrophic equation in $\textbf{T}^2$. We prove that this system possesses time-dependent periodic solutions, bifurcating from a smooth steady solution, ... More
On a uniformly distributed phenomenon in matrix groupsMar 21 2011Sep 02 2013We show that a classical uniformly distributed phenomenon for an element and its inverse in ($\mathbb{Z}/n\mathbb{Z})^{*}$ also exists in $\textrm{GL}_{n}(\mathbb{F}_{p})$. A $\textrm{GL}_{n}(\mathbb{F}_{p})$ analogy of the uniform distribution on modular ... More
