The discriminant — From a quadratic equation to dynamic nonlinear systems
Most mathematics students don't understand the potential of the discriminant. Usually discussed while learning the Quadratic Formula to solve quadratic equations, students learn its use for the classification of type and ...
Optimal control of a biological waste-water treatment plant
In this paper a mathematical model of a biological waste cleaning plant is created and investigated. The model is described by a nonlinear system of two differential equations with one bounded control. An optimal control ...
Structural and thermodynamic studies of a DNA i-motif: Investigating the monomer, dimer, and tetramer human telomere sequence context
Telomeres are protein DNA complexes found at the ends of eukaryotic chromosomes. The human telomere sequence has a G-rich strand, (TTAGGG), complemented to a C-rich strand, (CCCTAA). Previous studies of the G-rich strand ...

Inverting a positive definite matrix: A comparative study of two algorithms
The purpose of the paper is to investigate the efficiency of two matrix-inverting algorithms that are restricted to positive definite matrices. The selected algorithms are a Guass-Jordan method and a gradient projection ...
General passion scale (Gen-PS) toward validation of passion as a general trait-like personality construct
Although research regarding passion has been advancing, an explicit definition of passion has not been derived, nor has a universally accepted, standardized, and reliable method of measuring passion been constructed. This ...
Using data mining techniques to identify “the best” operational patterns for enrollment modeling
For any Educational Institution it is very important to know the number of new students and the number of returning students. Based on these numbers, there could be conducted predictions of the budget that the institution ...
A longitudinal analysis using auxiliary information to model retention in undergraduate students
Attrition is an issue for colleges and universities, and attempts to retain students are becoming more and more difficult. This study focuses on predicting student attrition of first time incoming (FTIC) students over a ...
Making the grade: A study of academic success
Freshmen account for more than fifty percent of students who drop out before completing their degree, which means that increasing the success rates for freshmen is a critical challenge for many colleges and universities. ...
Human glutathione synthetase residues Valine 44 and Valine 45 are required for subunit stability and negative cooperativity
Valine 44 and Valine 45 serve as important residues for human glutathione synthetase (hGS) function and stability given their location at the dimer interface of this enzyme. Computational studies suggest Val45 has more ...
