The local, covariant, continuous, anticommuting and nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for all the fields of a (0 + 1)-dimensional spinning relativistic particle are obtained in the framework of augmented superfield approach to BRST formalism. The trajectory of this super-particle is parametrized by a monotonically increasing parameter τ that is em...

Based on our present working-experience with a Mapuche kimche (sage) and logko (spiritual political leader), we aim at intervening in broader debates the intersubjective intercultural production of knowledge. To do so, pay special attention to contemporary mandates pervasive conceptions about forms practicing better, more proper anthropology. We approach problem from three different viewpoints:...

Early Acheulian bifaces appear to be characterized by seven basic operations. After a brief description of each operation, I propose how the pattern of that operation had the capacity to serve as an analogue for a concept of the soul that could be expressed both in self-concept (selfobject) and interpersonal relations (object relations). 1. A 'core' is flaked and the flake is trimmed, in turn, ...

Some of the key cohomological features of the two (1+1)-dimensional (2D) free Abelianand self-interacting non-Abelian gauge theories (having no interaction with matter fields) are briefly discussed first in the language of symmetry properties of the Lagrangian densities and the same issues are subsequently addressed in the framework of superfield formulation on the four (2+ 2)-dimensional super...

In the framework of superfield approach, we derive the local, covariant, continuous and nilpotent (anti-)BRST and (anti-)co-BRST symmetry transformations on the U(1) gauge field (Aμ) and the (anti-)ghost fields ((C̄)C) of the Lagrangian density of the two (1 + 1)-dimensional QED by exploiting the (dual-)horizontality conditions defined on the four (2+2)-dimensional supermanifold. The long-standi...

This paper presents a study of visual perception through the application eye-tracking prehistoric ceramics. The is feasible methodology to understand agency material culture quantitative techniques, which allows for analyses possible relationships between visual-perceptual behaviour, and social complexity. In particular, horizontality gaze shown be associated with pottery from early periods its...

Thick sequences of layered deposits are found in the Valles Marineris, Mars [I-31. They exhibit fine, nearly horizontal layering, and are present as isolated plateaus of what may once have been more extensive deposits. Individual sequences of layered deposits are as thick as 5 km. We have argued previously that the morphology of the deposits is most consistent with origin in standing bodies of ...

The local, covariant, continuous and off-shell (as well as on-shell) nilpotent (anti-)BRST symmetry transformations are derived for a one (0+1)-dimensional free scalar relativistic particle in the framework of superfield formalism. The trajectory (i.e. the worldline) of the free particle, parametrized by a monotonically varying evolution parameter τ , is embedded in aD-dimensional flat Minkowsk...

In the framework of usual superfield approach, we derive the exact local, covari-ant, continuous and off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the U(1) gauge field (A µ) and the (anti-)ghost fields ((¯ C)C) of the Lagrangian density of a four (3 + 1)-dimensional QED by exploiting the horizontality condition defined on the six (4 + 2)-dimensi...
