高阶导数的运算 (x^{a})^{(n)}=x^{a-n} \prod_{k=0}^{n-1} (a-k) (\frac{1}{x})^{(n)}=(-1)^n\frac{n!}{x^{n+1}} \quad\quad (n=1,2,...)(\ln x)^{(n)}=(-1)^{(n-1)}\frac{(n-1)!}{x^{n}} \quad\quad (n=2,3,...)...
The sum rule, product rule, and chain rule produce new derivatives from the derivatives ofxn, sin(x) andex. The Fundamental Theorem of Calculus says that the integral inverts the derivative.

Photonic crystals (PC) are periodically designed artificial structures that manipulate the flow of light, and their periodicity can be one, two, or even three dimensional2. PCs have many remarkable properties that make it indispensable to control the photon movement using structures such as ...
4.1.1 A first change of variables It is possible to make the change of variable xi = log(Si), i = 1, …, d; calling x the vector (x1,…, xd) and P˜ the function, P˜(x,t) = P(S, t), the final value problem (4.5) (4.6) becomes (4.8)(∂P˜∂t+L˜P...
DNA methylation is a key epigenetic regulator contributing to cancer development. To understand the role of DNA methylation in tumorigenesis, it is important to investigate and compare differential methylation (DM) patterns between normal and case sample
(19)y″+p(x)y′+q(x)y=f(x) If f(x) = 0, it is a special case of the second order equation and it is called a homogeneous equation. (20)y″+p(x)y′+q(x)y=0 This equation will have two solutions y1 and y2. Example: For equation y″+k2y=0 the two solutions are: ...
Genes are only shown if the posterior z-score was greater than 2 in magnitude in at least one of the DE analyses. Genes are colored by the “null model” expression rate. The Q-Q plot (C) compares the overall distribution of posterior z-scores for B cells and myeloid cells (x-axis)...
