A protein structural alphabet and its substitution matrix CLESUM

Wei-Mou Zheng, Xin Liu

By using a mixture model for the density distribution of the three pseudobond angles formed by atoms of four consecutive residues, the local structural states are discretized…

Cosmological Evolution of Interacting Phantom Energy with Dark Matter

Zong-Kuan Guo, Rong-Gen Cai, Yuan-Zhong Zhang

We investigate the cosmological evolution of an interacting phantom energy model in which the phantom field has interaction with the dark matter. We discuss the existence and stabi…

Quantum information storage and state transfer based on spin systems

Z. Song, C. P. Sun

The idea of quantum state storage is generalized to describe the coherent transfer of quantum information through a coherent data bus. In this universal framework, we comprehensive…

Energy Spectra of Anti-nucleons in Finite Nuclei

G. Mao, J. Gong, H. Stöcker +1

The quantum vacuum in a many-body system of finite nuclei has been investigated within the relativistic Hartree approach which describes the bound states of nucleons and anti-nucle…

K-Chameleon and the Coincidence Problem

Hao Wei, Rong-Gen Cai

In this paper we present a hybrid model of k-essence and chameleon, named as k-chameleon. In this model, due to the chameleon mechanism, the directly strong coupling between the k-…
