The phrase "area of differential" is not correct and may be confusing in written English.
It could be used in contexts related to mathematics or statistics, but it is more common to see "differential area" or "area of differentiation."
Example: "In calculus, we often study the area of differential equations to understand their behavior."
Alternatives: "differential region" or "area of variation."
Step 3 selects the low-frequency part by searching the notch area of differential phase difference.
This concept is new and may be useful in the area of differential equations.
It is also worthwhile mentioning a growinginterest in applications of the methods of the fixed point theory to semigroups ofnonlinear mappings and applications to the area of differential and integralequations (see e.g.[10, 19, 20]).
Applications in the area of differential diagnosis, guiding treatment as well as prognosis are still developing.
fMRI analysis consisted of a 1) region of interest (ROI) approach to detect differences in selected motor areas within brain and 2) a voxel-wise whole brain comparison to find areas of differential activation that were not defined a priori between the older and younger group.
These methods have the possibility of providing unique insight into the molecular characterization of tissue by enabling discrete analysis of areas of differential pathology.
Most methods for biological analyses focus on either searching for new disease subtypes through cluster analysis (Clifford et al. 2011; Siegmund et al. 2004), or looking for areas of differential DNA methylation between samples under different conditions (Jaffe et al. 2012a; Langevin et al. 2011).
Non-homogeneous linear differential equations is an important area of complex differential equations, which has a large number of potential applications.
As the fundamental issues of modern impulse theory, the existence and uniqueness of solutions to impulsive differential systems have been studied extensively in recent years, especially in the area of impulsive differential equations with fixed moments, see the monographs of Lakshmikantham et al.[7], Samoilenko and Perestyuk [8], the literature [9, 10] and references therein.
There has been a significant development in the area of impulsive differential equations with fixed moments.
Kuang has also maintained an active mathematics research program on dynamical systems--particularly in the area of functional differential equations.
