A Preliminary Study on the Assessment of Restrictedness in High Functioning Autism
Restricted and repetitive behavior is one of the two cardinal symptoms of autism, and it might find its root in the neuropsychological trait of “insistence on sameness”. Conceived from the perspective of embod...

Nonsynchronous bifurcation of SIRS epidemic model with birth pulse and pulse vaccination
In this paper, we construct an SIRS epidemic model with birth pulse and pulse vaccination at the different fixed moment. The stability of the infection-free periodic solution is obtained by using the Poincaré ...
