Generalized Ricci solitons and Einstein metrics on weak K-contact manifolds

open access: yesCommunications in Analysis and Mechanics, 2023
We study so-called "weak" metric structures on a smooth manifold, which generalize the metric contact and $ K $-contact structures and allow a new look at the classical theory.

The Quaternionic Hardy Space and the Geometry of the Unit Ball

open access: yesBruno Pini Mathematical Analysis Seminar, 2015
The quaternionic Hardy space of slice regular functions H2(B) is a reproducing kernel Hilbert space. In this note we see how this property can be exploited to construct a Riemannian metric on the quaternionic unit ball B and we study the geometry arising

Critical review of the levelised cost of energy metric

open access: yesSouth African Journal of Industrial Engineering, 2016
The purpose of this paper is to critically review the ‘levelised cost of energy’ metric used in electricity project development. This metric is widely used, because it is a simple metric to calculate the cost per unit of electricity for a given ...

Why pitch sensitivity matters: Event-related potential evidence of metric and syntactic violation detection among Spanish late learners of German.

open access: yesFrontiers in Psychology, 2011
Event-related potential (ERP) data in monolingual German speakers have shown that sentential metric expectancy violations elicit a biphasic ERP pattern consisting of an anterior negativity and a posterior positivity (P600).

Completeness results for metrized rings and lattices [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2019
The Boolean ring $B$ of measurable subsets of the unit interval, modulo sets of measure zero, has proper radical ideals (for example, $\{0\})$ that are closed under the natural metric, but has no prime ideal closed under that metric; hence closed radical
