Localization of multiple dipoles: Mathematical programming approaches

Brain Topography, 1989
Although there has been progress in EEG and evoked potential analysis, the identification of underlying neural activity has eluded researchers despite its importance. This paper introduces the application of mathematical programming techniques to the "inverse" problem of three-dimensional localization of brain activity from scalp potentials ...

Multiplicity and concentration results for a class of critical fractional Schrödinger–Poisson systems via penalization method

Communications in Contemporary Mathematics, 2018
We deal with the multiplicity and concentration of positive solutions for the following fractional Schrödinger–Poisson-type system with critical growth: [Formula: see text] where [Formula: see text] is a small parameter, [Formula: see text], [Formula ...

SIMPLIFIED MATHEMATICS FOR MULTIPLE BIOASSAYS

Acta Endocrinologica, 1960
ABSTRACT Gaddum's simplified system of computation for the analysis of biological parallel-line assays is extended to the assay of several unknown preparations simultaneously against the same standard, using up to four dose levels of each preparation.

Existence and multiplicity of solutions for a quasilinear Choquard equation via perturbation method

Journal of Mathematics and Physics, 2018
In this paper, we consider the existence and multiplicity of solutions for the following quasilinear Choquard equation: −Δu+V(x)u−uΔ(u2)=(|x|−μ*|u|p)|u|p−2u,   x∈RN, where N ≥ 3, μ∈(0,N+22), p∈(2,4N−4μN−2).

Teaching Mathematics with Technology: Multiples

The Arithmetic Teacher, 1987
Throughout children's study of mathematics, the concept of multiples and the skills associated with multiples play an important role. Initially, children's love of rhymes such as “two, four, six, eight, meet me at the garden gate” is extended to include skip counting with numbers other than 2.

Multiple-choice tests: pure mathematics

1985
In multiple-choice papers a large number of questions have to be done in the allocated time. Hence,it is essential to work quickly and to recognize any possible short cuts. In this chapter the two main styles of multiple-choice question are considered in detail and the various methods of approach are described.

Fostering Mathematical Thinking through Multiple Solutions

Mathematics Teaching in the Middle School, 2000
The reform movement in school mathematics advocates communication as a necessary component for learning, doing, and understanding mathematics (Elliott and Kenney 1996). Communication in mathematics means that one is able not only to use its vocabulary, notation, and structure to express ideas and relationships but also to think and reason ...

Multiplicity of closed Reeb orbits on prequantization bundles

Israel Journal of Mathematics, 2017
We establish multiplicity results for geometrically distinct contractible closed Reeb orbits of non-degenerate contact forms on a broad class of prequantization bundles.
