Q factors for antennas in dispersive media [PDF]
, 2014 Stored energy and Q-factors are used to quantify the performance of small antennas. Accurate and efficient evaluation of the stored energy is also essential for current optimization and the associated physical bounds. Here, it is shown that the frequency

Degree growth of monomial maps and McMullen's polytope algebra
, 2011 We compute all dynamical degrees of monomial maps by interpreting them as mixed volumes of polytopes. By exploiting further the isomorphism between the polytope algebra of P. McMullen and the universal cohomology of complete toric varieties, we construct

The Millennium Run Observatory: First Light
, 2012 Simulations of galaxy evolution aim to capture our current understanding as well as to make predictions for testing by future experiments. Simulations and observations are often compared in an indirect fashion: physical quantities are estimated from the ...

The representation theorem of the Robinson hybrid
Қарағанды университетінің хабаршысы. Математика сериясыThis research lies within the domain of model theory, which investigates the properties of, broadly speaking, incomplete theories. The article introduces novel methods for classifying classes of structures whose associated theories are Jonssonian ...

Life-history variation and age at maturity in Eurasian Perch (Perca fluviatilis L.) [PDF]
, 2003 This thesis deals with life-history variation in perch, with special focus on age at maturity. We conducted field studies to uncover the variation within short geographic distances and a literature review to study variation on a large geographic scale in

Topological representation of matroids from diagrams of spaces [PDF]
, 2010 Swartz proved that any matroid can be realized as the intersection lattice of an arrangement of codimension one homotopy spheres on a sphere. This was an unexpected extension from the oriented matroid case, but unfortunately the construction is not ...

Point Defects and Localized Excitons in 2D WSe2
, 2019 Identifying the point defects in 2D materials is important for many applications. Recent studies have proposed that W vacancies are the predominant point defect in 2D WSe2, in contrast to theoretical studies, which predict that chalcogen vacancies are ...

Stored energies for electric and magnetic current densities
, 2016 Electric and magnetic current densities are an essential part of electromagnetic theory. The goal of the present paper is to define and investigate stored energies that are valid for structures that can support both electric and magnetic current ...
