A note on inverses of cyclotomic mapping permutation polynomials over finite fieldsJan 16 2016In this note, we give a shorter proof of a result of Zheng, Yu, and Pei on the explicit formula of inverses of generalized cyclotomic permutation polynomials over finite fields. Moreover, we characterize all these cyclotomic permutation polynomials that ... More
The w-index: A significant improvement of the h-indexMay 30 2008Jun 13 2008I propose a new measure, the w-index, as a particularly simple and useful way to assess the integrated impact of a researcher's work, especially his or her excellent papers. The w-index can be defined as follows: If w of a researcher's papers have at ... More
Charmonium hadronic decays and the OZI rule violation effectsDec 19 2006We discuss the scalar meson mixing scenario and present an OZI rule violation mechanism for understanding the scalar productions in charmoium hadronic decays. We stress that the OZI violation could play a key role in disentangling the structure of the ... More
Nucleonic resonance excitations with linearly polarized photon in $γp\to ωp$Oct 11 2000In this work, an improved quark model approach to the $\omega$ meson photo-production with an effective Lagrangian is presented. The {\it t}-channel {\it natural}-parity exchange is taken into account through the Pomeron exchange, while the {\it unnatural}-parity ... More
Study the exotic $Θ^+$ in polarized photoproduction reactionsFeb 03 2005We present an analysis of a Beam-Target double polarization asymmetry in $\gamma n\to \Theta^+ K^-$. We show that this quantity can serve as a filter for the determination of the $\Theta^+$'s spin-parity assignment near threshold. It is highly selective ... More
Critical cooling rate for the glass formation of ferromagnetic Fe40Ni40P14B6 alloyNov 26 2006Nov 29 2006Bulk ferromagnetic amorphous Fe-Ni-P-B alloys in rod shape were formed by a rapid solidification technique. The largest amorphous specimen prepared had a diameter of ~2.5 mm and the corresponding cooling rate for the glass formation of this alloy system ... More
