In this paper, we introduce the condition of θ-locality which can be used as a substitute for microcausality in quantum field theory on noncommutative spacetime. This condition is closely related to the asymptotic commutativity which was previously used in nonlocal QFT. Heuristically, it means that the commutators of observables behave at large spacelike separation like exp(−|x − y|2/θ), where ...

models for spatial data propose a list of types and fundamental operators that are needed in spatial data systems. The ROSE algebra (Güting 1994, Güting and Schneider 1995) and OpenGIS abstract specification (Open GIS Consortium 1999) both provide a similar list of spatial operators. (A comparison between the two models can be found in Dilo (2006).) To present the list of operators, we follow h...

The double-controlled metric-type space (X,D) is a metric in which the triangle inequality has form D(η,μ)≤ζ1(η,θ)D(η,θ)+ζ2(θ,μ)D(θ,μ) for all η,θ,μ∈X. maps ζ1,ζ2:X×X→[1,∞) are called control functions. In this paper, we introduce novel generalization of double-composed space, where D(η,μ)≤αD(η,θ)+βD(θ,μ) our new functions α,β:[0,∞)→[0,∞) composed D inequality, multiplied with D. We establish s...

Phonemes with restricted distribution represent an interesting analytic challenge. Well-known sources include the adoption of certain phonemes from other languages in borrowed words, emerging phonemic splits, and special phonological subsystems (e.g. ideophones). This paper aims to widen our conception such marginal phonemes, by incorporating another source: specific vocal gestures called into ...

This article proposes a revised model of the genesis Castilian Spanish /?/, based on (i) precise tracking across Late Middle Ages orthographical d ? z change in preconsonantal coda position and (ii) potential for auditory indeterminacy between denti-alveolar variants [s] non-sibilant [?]. According to findings, two phonemes, /?/ /ð/, are likely have come into existence by early 1500s, merger at...

Widely linear estimation for complex-valued data allows for a unified treatment of both second order circular (proper) and non-circular (improper) signals. We propose the complex dual channel (CDC) estimation technique as an alternative to widely linear estimation to both gain further insights into complex valued minimum mean square error (MMSE) estimation and to design computationally efficien...
