In this paper a novel method is proposed that determines the finite and infinite frequency structure of any rational matrix. For a polynomial matrix, a natural relationship between the rank information of the Toeplitz matrices and the number of the corresponding irreducible elementary divisors (IREDs) in its Smith form is established. These special Toeplitz matrices correspond to the derivative...

heartworm disease is caused by dirofilaria immitis in dogs and cats. dirofilariasis is clinically considered very important, because of its severe and life threatening disease in case of even light infection. cats are infected much less commonly, even in areas which present heavily infected dogs. after clinical examination blood samples were collected from 120 companion and stray adult cats in ...

Virtual companions that interact with users in a socially complex environment require a wide range of social skills. Displaying curiosity is simultaneously a factor to improve a companion’s believability and to unobtrusively affect the user’s activities over time. Curiosity represents a drive to know new things. It is a major driving force for engaging learners in active learning. Existing rese...

Companion diagnostics are integral to the application and success of personalized medicine. In oncology, many companion diagnostics are molecular-based, including a number of fluorescence in situ hybridization (FISH) based companion diagnostics. Here, we review the currently approved FISH based companion diagnostics and evaluate several new FISH assays as potential companion diagnostics.

An approach is presented to get interconnections between the Fisher information matrix of an ARMAX process and a corresponding solution of a Stein equation. The case of algebraic multiplicity greater than one and the case of distinct eigenvalues are addressed. Appropriate links are constructed for these two cases by applying a factorization both for the Fisher information matrix and for a corre...
