An Hermitian matrix A is said to be positive semi-definite or nonnegative definite, written as A ≥ 0, if x ∗ A x ≥ 0, ∀ x ∈ C n.
However, recently introduced modified self-assembly method i.e. MGSA has given an excellent opportunity for assembling biomaterials at a definite spatial as well as archistructural arrangements [11].
There is enough evidence, based on social experiments, to show the more people involved in making a decision, the less likely they are to arrive at something definite as opposed to a consensus.
Computerizing CPGs and coupling them with drug databases for more complete information and improved clinical adaptability represents a definite improvement as far as physicians are concerned.
"I thought we made some definite strides as a team," said Greg Schiano, Rutgers's first-year coach.
And despite chemists' acceptance of the law of definite proportions as a criterion for substancehood, chemical complexities such as the discovery of the Berthollides muddied the waters.
And while no one is exactly certain what its main use will be, there are no shortage of signs pointing to a definite role as a new way to consume written media.
This information is a definite requirement as a boundary condition by the more sophisticated hygrothermal models such as LATENITE and WUFIZ which consider both vapor and liquid moisture flows.
An Hermitian matrix A is said to be positive semidefinite or nonnegative definite, written as A ≥ 0, if (see, e.g., [[1], p. 159]) x H A x ≥ 0, ∀ x ∈ ℂ n, (1.2).
First, we construct a positive definite function as a Lyapunov function: V t) = sum_{i = 1}^{r} bigl{ lambda_{i}bigl xi (t bigr)varepsilon_{i}^{T}X_{i} varepsilon_{i} + eta_{1}a^{2} + eta_{3}c^{2} + h_{1}(t) bigr}.
