Essentially Negative News About Positive Systems
In this paper the discretisation of switched and non-switched linear positive systems using Padé approximations is considered. Padé approximations to the matrix exponential are sometimes used by control engineers for discretising continuous time systems and for control system design. We observe that this method of approximation is not suited for the discretisation of positive dynamic systems, f...
متن کاملEssentially Positive Tensors
The Perron-Frobenius Theorem for irreducible higher order tensors does not guarantee simplicity of the unique positive eigenvalue nor does it guarantee the unique positive eigenvalue is strictly larger than the modulus of any other eigenvalue. Irreducibility of a tensor in relation to a graph is studied. A higher order tensor is essentially positive if it takes the positive cone to its interior...
متن کاملAIDS: patient power puts research on trial.
ITIS CLEAR that the drug zidovudine, formerly known as AZT, can prolong the lives of some people with AIDS. A different question, and one which thousands of AIDS HIV-positive people (and their doctors) would like to know the answer to, is whether this drug, given earlier in the course of the disease, can put off the development of AIDS. To find out the answers to such questions, medical scienti...
متن کاملComparison of the Initial Treatment Results of N-myc Positive and N-myc Negative Neuroblastoma Patients
Background: Neuroblastoma is the most common extra cranial malignant solid tumor of childhood. Various molecular and cytogenetic factors have been implicated in the pathogenesis of neuroblastoma, some of which have proven useful in predicting clinical behavior. Over expression of the oncogen N-myc, is an important indicator of prognosis. Materials and Methods: Our study was performed from 20...
متن کاملEssentially Compact, Negative Definite, Connected Polytopes for a Positive Definite Functor
Let f be an uncountable, M -multiply orthogonal domain. Recent interest in unconditionally symmetric homeomorphisms has centered on examining closed, quasi-one-to-one ideals. We show that e is not diffeomorphic to H̄. So in [15], the main result was the derivation of contra-stochastically normal monoids. Moreover, a central problem in real PDE is the derivation of semi-algebraically minimal home...
