Some TSEs stick to a single species , while others ignore such boundaries .
有些TSEs只针对某一物种，而其他TSEs却设有种的界限。
Known as transmissible spongiform encephalopathies , or TSEs , they arise spontaneously in species as varied as sheep , cattle , mink , deer and people .
如我们所知的传染性海绵状脑病（TSEs），在不同物种如羊、牛、水貂、鹿和人中同时存在。
Because of the structural characteristics of the rabbit prion protein ( RaPrPC ) itself , rabbits are one of the few mammalian species that appear to be resistant to TSEs .
The implications for vaccine safety of the emergence of certain transmissible spongiform encephalopathies ( TSEs ) have received the attention of the Committee for several years .
Starting from the classical assignment problem , this paper deals with the assignment under fuzzy environments - a problem of unclear coefficients in the coefficient matrix . The assignment information is obtained with the help of the fuzzy tses , and the optimal assignment is achieved with the classical methods .
