We study the properties of pseudo entropy, a new generalization entanglement in free Maxwell field theory $d = 4$ dimension. prepare excited states by different components strengths located at Euclidean times acting on vacuum. compute difference between R\'{e}nyi entropy and ground state observe that changes significantly near boundary subsystems vanishes far away from boundary. Near subsystems...

Abstract We review our recent results on pseudo-hermitian random matrix theory which were hitherto presented in various conferences and talks. (Detailed accounts of work will appear soon separate publications.) Following an introduction this new type matrices, we focus two specific models matrices are with respect to a given indefinite metric B. Eigenvalues either real, or come complex-conjugat...

Notions of the 'postmodern' pervade various fields of study, but have rarely been applied to the practice and theory of nursing. This paper uses some conceptions of the 'postmodern' to remedy this. Though there are many contested usages of the term, here 'postmodern' will be used broadly in a periodical sense to trace changes in society and culture from the 'modernism' of the 18th and 19th cent...

in this work we use density functional theory based on the ultra-soft pseudo-potential to calculate thestructural, mechanical and thermal properties of narrow single walled bn, aln and gan nanotubes.the electron-electron interactions were expressed within the local density approximation (lda). wehave also obtained the phonon dispersion and elastic constants of these nanotubes using the densityf...

In this paper, we give a novel abstract description of Szabo’s polycategories. We use the theory of double clubs – a generalisation of Kelly’s theory of clubs to ‘pseudo’ (or ‘weak’) double categories – to construct a pseudo-distributive law of the free symmetric strict monoidal category pseudocomonad onMod over itself qua pseudomonad, and show that monads in the ‘two-sided Kleisli bicategory’ ...

The complete homogeneous pseudo-Riemannian manifolds of constant non-zero curvature were classified up to isometry in 1961 [1]. In the same year, a structure theory [2] was developed for complete fiat homogeneous pseudo-Riemannian manifolds. Here that structure theory is sharpened to a classification. This completes the classification of complete homogeneous pseudo-Riemannian manifolds of arbit...
