Quark rotation asymmetry and baryon magnetic moments
W. Li, X. Cai
Quark rotation asymmetry is proposed in calculating baryon magnetic moments. After taking into account interactions enforced on constituent quarks, assumed to be linear and Coulomb…

A new hierarchy of avalanches observed in Bak-Sneppen evolution model
W. Li, X. Cai
A new quantity, average fitness, is introduced in Bak-Sneppen evolution model. Through this new quantity, a new hierarchy of avalanches is observed in the evolution of Bak-Sneppen…

A model of evolution with interaction strength
W. Li, X. Cai
Interaction strength is introduced in a model of evolution in d-dimension space. It is realized by imposing a constraint concerning 2d differences of fitnesses between that of any…
