Differential Parametric Formalism for the Evolution of Gaussian States: Nonunitary Evolution and Invariant States

open access: yesEntropy, 2020
In the differential approach elaborated, we study the evolution of the parameters of Gaussian, mixed, continuous variable density matrices, whose dynamics are given by Hermitian Hamiltonians expressed as quadratic forms of the position and momentum ...

Invariant Tests for Means with Covariates

open access: yesThe Annals of Statistics, 1980
We consider the problem of testing a hypothesis about the means of a subset of the components of a multivariate normal distribution with unknown covariance matrix, when the means of a second subset (the covariates) are known. Because of the possible correlation between the two subsets, information provided by the second subset can be useful for ...

Invariant Means on Banach Spaces [PDF]

open access: yesAnnales Mathematicae Silesianae, 2017
Abstract In this paper we study some generalization of invariant means on Banach spaces. We give some sufficient condition for the existence of the invariant mean and some examples where we have not it.

Thickness in topological transformation semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
This article deals with thickness in topological transformation semigroups (τ-semigroups). Thickness is used to establish conditions guaranteeing an invariant mean on a function space defined on a τ-semigroup if there exists an invariant mean on its ...

A new perspective on the spatio-temporal variability of soil moisture: temporal dynamics versus time-invariant contributions [PDF]

open access: yesHydrology and Earth System Sciences, 2012
Knowledge about the spatio-temporal variability of soil moisture is essential to understand and predict processes in climate science and hydrology. A significant body of literature exists on the characterization of the spatial variability and the rank ...

Some Spaces of Double Sequences Obtained through Invariant Mean and Related Concepts

open access: yesAbstract and Applied Analysis, 2013
We introduce some double sequences spaces involving the notions of invariant mean (or -mean) and -convergence for double sequences while the idea of -convergence for double sequences was introduced by Çakan et al.

Invariant Means And Multiplicative Matrices

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1980
Schaefer [7] has introduced the concept of a conservative and ct regular matrices and obtains necessary and suHicient conditions to characterize these classes of matrices.In the present paper authors have defîned (c, VCT)|3-matrices and (cOp,VQ)p and ohtain necessary and sufficient conditions to characterize them.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).
