Riesz bases and positive operators on Hilbert space [PDF]
It is shown that a normalized Riesz basis for a Hilbert space H (i.e., the isomorphic image of an orthonormal basis in H) induces in a natural way a new, but equivalent, inner product on H in which it is an orthonormal basis, thereby extending the sense ...

Recognition for Positive Behavior as a Critical Youth Development Construct: Conceptual Bases and Implications on Youth Service Development [PDF]
Recognition for positive behavior is an appropriate response of the social environment to elicit desirable external behavior among the youth. Such positive responses, rendered from various social systems, include tangible and intangible reinforcements ...

Bases for shape preserving curves
The shape preserving properties of a curve in \(\mathbb{R}^2\) depend on the properties of the function basis we use in its representation. Both sign consistent and totally positive bases have shape preserving properties useful in Computer Aided ...

Elementary Atoms, Positive Bases and Reay Systems
The chapter begins with some basic non-degeneracy characterizations. The concept of an elementary atom is given. It corresponds to the notion of atom when factoring using rational sequences rather than ordinary sequences.

Antibacterial activity for Tin-cephalexin Schiff bases against Bacillus Pumilus and Candida albicans
In the current study, cephalexin and two beta-lactam antibiotics were combined with four distinct aldehydes: 3-hydroxybenzaldehyde, 4-dimethylaminobenzaldehyde, 4-methoxybenzaldehyde, and 4-bromobenzaldehyde, to synthesize Schiff bases.

An opportunistic indoors positioning scheme based on estimated positions [PDF]
Positioning requirements for mobile nodes in wireless (sensor) networks are largely increasing. However for indoors environments most of the existing solutions are expensive in terms of technology or infrastructure. We propose an indoors positioning scheme in which a static user collects self-estimated positions of collaborating peer nodes within radio

On the Total Positivity and Accurate Computations of r-Bell Polynomial Bases
A new class of matrices defined in terms of r-Stirling numbers is introduced. These r-Stirling matrices are totally positive and determine the linear transformation between monomial and r-Bell polynomial bases.
