To examine whether proviral load is important for transmission between spouses, since we have previously found that the proviral load of HIV-2 predicts the severity of infection.Proviral load was examined in 121 HIV-2-infected adults in a rural area of Guinea-Bissau. For the 68 subjects who...
The percentage of energy from fat in diets has been thought to be an important determinant of body fat, and several mechanisms have been proposed. Comparisons of diets and the prevalence of obesity between affluent and poor countries have been used to support this relationship, but these contrasts...
For a 2×2 Matrix For a2×2matrix (2 rows and 2 columns): A = abcd The determinant is: |A| = ad − bc "The determinant of A equals a times d minus b times c" It is easy to remember when you think of a cross: Blueis positive (+ad), ...

If AneB, AB = BA and A^(2)=B^(2), then the value of the determinant of matrix A+B is (where A and B are square matrices of order 3xx3 )
By the use of thedeterminant of any m×n matrix,Cauchy mean value theorem is generalized to any multiple functions. 利用任意一个m×n矩阵的行列式定义,将柯西中值定理推广到任意多个一元函数的情形,并得到了拉格朗日定理的一个几何意义上的推广:对任意正整数n,存在一条过点A(a,f(a))和B(b,f(b))的...
