Field theories on ρ-deformed Minkowski space-time

open access: yesJournal of High Energy Physics, 2023
We study one-loop perturbative properties of scalar field theories on the ρ-Minkowski space. The corresponding star-product, together with the involution are characterized from a combination of Weyl quantization and defining properties of the convolution

Conull hypersurfaces in Minkowski space [PDF]

open access: yesProceedings of the American Mathematical Society, 1982
A submanifold of M = Gr(2, C 4 ) {\mathbf {M}} = {\text {Gr(2,}}{{\mathbf {C}}^4}{\text {)}} is conull when its conormal space is in ...

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Liquid Phase TEM of Diffusing Emulsion Droplets

open access: yesSmall, EarlyView.
Motion of emulsion droplets was observed via in situ liquid phase transmission electron microscopy. Analysis revealed that the motion is self‐affine and influenced by multiple stochastic processes, as well as a fractal landscape created by the electron beam.

DUAL TIMELIKE NORMAL AND DUAL TIMELIKE SPHERICAL CURVES IN DUAL MINKOWSKI SPACE

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009
: In this paper, we give characterizations of dual timelike normal and dual timelike spherical curves in the dual Minkowski 3-space and we show that every dual timelike normal curve is also a dual timelike spherical curve.

Minkowski box from Yangian bootstrap

open access: yesJournal of High Energy Physics, 2021
We extend the recently developed Yangian bootstrap for Feynman integrals to Minkowski space, focusing on the case of the one-loop box integral. The space of Yangian invariants is spanned by the Bloch-Wigner function and its discontinuities.

K-Poincare-Hopf algebra and Hopf algebroid structure of phase space from twist

open access: yes, 2013
We unify k-Poincare algebra and k-Minkowski spacetime by embeding them into quantum phase space. The quantum phase space has Hopf algebroid structure to which we apply the twist in order to get k- deformed Hopf algebroid structure and k-deformed phase ...

Integrated Learning‐Based Ageing Assessment of Silicone Rubber

open access: yesHigh Voltage, EarlyView.
ABSTRACT The surface ageing of silicone rubber composite insulators, widely used in power systems, poses significant challenges. This study integrates Fourier transform infrared (FTIR) spectroscopy with machine learning to evaluate ageing states and explore underlying mechanisms under various environmental conditions.

A-topology for Minkowski space [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1979
AbstractWe consider in this paper a topology (which we call the A-topology) on Minkowski space, the four-dimensional space–time continuum of special relativity and derive its group of homeomorphisms. We define the A-topology to be the finest topology on Minkowski space with respect to which the induced topology on time-like and light-like lines is one ...

Star-products for Lie-algebraic noncommutative Minkowski space-times

open access: yesJournal of High Energy Physics
Poisson structures of the Poincaré group can be linked to deformations of the Minkowski space-time, classified some time ago by Zakrewski. Based on this classification, various quantum Minkowski space-times with coordinates Lie algebras and specific ...
