Hurwitz rational functions [PDF]
, 2011 A generalization of Hurwitz stable polynomials to real rational functions is considered. We establish an analog of the Hurwitz stability criterion for rational functions and introduce a new type of determinants that can be treated as a generalization of ...

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

On rational functions without Froissart doublets
, 2017 In this talk we consider the problem of working with rational functions in a numeric environment. A particular problem when modelling with such functions is the existence of Froissart doublets, where a zero is close to a pole.

Журнал Белорусского государственного университета: Математика, информатика, 2019 The subspace of rational distributions was considered it this paper. Distribution is called rational if it has analytical representation f = (f+, f-) where functions f+ and f- are proper rational functions.

Least Order Coprime Factorizations of Rational Matrices: The Canonical Case [PDF]
, 1998 Given an arbitrary real rational matrix G and a domain Gamma g in the closed complex plane we develop a complete theory of coprime factorizations of G over Gamma g having denominators of least possible McMillan degree.

Molecular Oncology, EarlyView.We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Sharper upper bounds on maximum modulus for rational functions
Demonstratio MathematicaWe study upper bounds for rational functions r(z)=p(z)w(z) $r\left(z\right)=\frac{p\left(z\right)}{w\left(z\right)}$ , where w(z)=∏j=1n(z−λj),|λj|>1, $w\left(z\right)={\prod }_{j=1}^{n}\left(z-{\lambda }_{j}\right), \vert {\lambda }_{j}\vert { >}1,$ and

On Multivariate Rational Function Decomposition
Journal of Symbolic Computation, 2002 The authors discuss several notions of decomposition for multivariate rational functions, and they present algorithms for decomposing multivariate rational functions over an arbitrary field. They also provide a very efficient method to decide if a unirational field has transcendence degree one, and in the affirmative case to compute the generator.

AN APPLICATION OF THE RATIONAL EXPECTATIONS HYPOTHESIS IN THE U.S. BEEKEEPING INDUSTRY [PDF]
A national beekeeping-industry model, assuming rational expectations, is presented. Consistent and asymptotically efficient estimates are obtained by a modified two-step two-stage least squares method.

Tangent spaces of rational matrix functions [PDF]
, 1998 We consider the task of determining tangent spaces for classes of rational matrix valued functions. Our analysis is based on methods from control theory, and in particular the theory of polynomial models.
