Poisson brackets that are spacetime covariant are presented for a variety of relativistic field theories. These theories include electromagnetism, general relativity, and general relativistic fluids and plasmas in Eulerian representation. The examples presented suggest the development of a general theory; the beginnings of such a theory are presented. Our covariant bracket formalism provides a ...

This paper describes an infrastructure that has been designed to deal with corpus-based variations that do not fall within the primary, physical variation of action verbs. We have first established three main categories of secondary variation--metaphor, metonymy and idiom--and criteria for creating types within these categories for each verb. The criteria rely heavily on the images that compose...

recently, researches on motor learning have illustrated that learning with effortless process supports learning under psychological stress. also, contextual interference and practice specificity theories are among those theories which investigate desired practice conditions. the current study aimed at identifying cognitive effort and effortless process based on contextual interference and pract...

Organizations frequently consider offshore systems development in the belief that projects can be completed at lower cost. While prices quoted by offshore vendors are often very appealing when compared with domestic vendors, additional risks must be considered when looking into offshore systems development. These risks typically take the form of intangible and indirect project costs which add t...

This paper presents the epistemic and political proposal of Modernity/ Coloniality group. I display conformation group, its members principal conceptual theoretical elaborations. The essay exposes with thoroughness contribution collective Modernity/Coloniality, in special, critic modernity colonialism which Europe named First World has put under “periphery”

We develop the general theory for construction of Extended Topological Quantum Field Theories (ETQFTs) associated with Costantino-Geer-Patureau quantum invariants closed 3-manifolds. In order to do so, we introduce relative modular categories, a class ribbon categories which are modeled on representations unrolled groups, and can be thought as non-semisimple analogue categories. Our approach ex...

the writers of this article seek to investigate thedramaturgy of howard barker in his the castle, staged in 1985 by royalshakespeare theatre, in order to discover and lay bare the baroque techniquesof representation in this political paly. relying on deleuze’s idea of baroquearchitecture and foucault’s theories of baroque representation, the writers tryto introduce this play as the expression o...

BACKGROUND The activities and work demands of medical professionals, including occupational physicians (OPs), fall into three categories: clinical, academic, and administrative. Work demands of an OP consist of these three categories and additional specialty specific roles and competencies. Research on the core competencies and skills required for OPs have identified high levels of consensus am...

We cannot help but categorize the visual world into objects like cats and faces. An intriguing new study shows that observers automatically discover informative fragments of visual objects during category learning.
