Hamburger such as , due to the occasional initial improper preparation of the meat, so caution is needed during handling and cooking. Because of the potential for food-borne illness, the USDA recommends hamburgers be cooked to an internal temperature of . If cooked to this temperature, they are considered well-done. Burgers can also be made with patties made from ingredients other than beef. For example, a "turkey burger" uses ground turkey meat, a "chicken burger" uses ground chicken meat. A "buffalo burger" uses ground meat from a bison, and an "ostrich burger" is made from ground seasoned ostrich meat. A deer
Hamburger moment problem "Jacobi matrix representation". This in turn leads to a "tridiagonal model" of positive Hankel kernels. An explicit calculation of the Cayley transform of "T" shows the connection with what is called the "Nevanlinna class" of analytic functions on the left half plane. Passing to the non-commutative setting, this motivates "Krein's formula" which parametrizes the extensions of partial isometries. The cumulative distribution function and the probability density function can often be found by applying the inverse Laplace transform to the moment generating function provided that this function converges.
