A Monte Carlo study of the mean-square radius of gyration R 2 g and scattering function P(k) with k the magnitude of the scattering vector for semiflexible ring polymers of the trefoil knot was conducted by the use of the discrete version of the Kratky–Porod (KP) wormlike ring model. The behavior of R 2 g and P(k) as functions of the reduced contour length λL, defined as the total contour lengt...

Since the introduction of fine needle aspiration biopsy (FNAB) in the 1970's, a preoperative diagnostic technique for thyroid follicular carcinoma has long been awaited. Many markers that distinguish follicular carcinomas from adenomas have been reported; however, most of them have not been confirmed to be beneficial for clinical use. Trefoil factor 3 (TFF3) is a relatively new family of peptid...

Hong Kong is an internationally renowned tourist city, so exploring profitability of the airport also great significance 
 for effectively developing economy Kong. This paper collects relevant influencing factors and profit. To avoid nonlinear correlation higher independent coefficient, logarithmic factor analysis are used. So variables divided into factor1 includes most factor2 aircraft m...
