The objectives of our study were threefold: (1) to develop a new approach—“association screening”—to statistically test the overall and specific parasite associations within

Per- turbation theory methods, as applied to neutron transport for sensitivity analysis, allow expressing in a systematic way the effects from a variation in the operators of the

In this paper, the erroneous derivation of Jacobian coeffi- cients of primitive constraint equations with respect to Euler parameters presented in literature is discussed, and cor-

The indirect method used existing inbreeding coefficients and calculation times were those being obtained in the repetitive uses incurred with optimisa- tion: they corresponded to

The mathematical derivation of this result consists of invoking the linearity of conditional expectation.. Because it is cheaper than the call with strike K 1 , it also allows a
