FRACTIONAL DIFFERENTIATION-BASED EDGE ENERGY DRIVEN ACTIVE CONTOURS FOR ROBUST IMAGE SEGMENTATION
ICTACT Journal on Image and Video Processing, 2021 In this paper, a new fractional differentiation-based active contour model for robust image segmentation is presented. A new edge energy is introduced, in which the contour evolution is driven by the difference between the fractional derivatives directed

Dimensional flow and fuzziness in quantum gravity: emergence of stochastic spacetime
, 2017 We show that the uncertainty in distance and time measurements found by the heuristic combination of quantum mechanics and general relativity is reproduced in a purely classical and flat multi-fractal spacetime whose geometry changes with the probed ...

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Imprint of quantum gravity in the dimension and fabric of spacetime
, 2017 We here conjecture that two much-studied aspects of quantum gravity, dimensional flow and spacetime fuzziness, might be deeply connected. We illustrate the mechanism, providing first evidence in support of our conjecture, by working within the framework ...

On fuzzy valued fractional iterative schemes
Ain Shams Engineering JournalThis work provides a two-step fractional iterative algorithm for fuzzy nonlinear equations (FNEs). The proposed algorithm combines the memory effect of the fractional derivatives and the uncertainty representation of the fuzzy numbers through the use of ...

Fuzzy Spheres in AdS/CFT Correspondence and Holography from Noncommutativity [PDF]
, 2000 We show that the existent fuzzy S^2 and S^4 models are natural candidates for the quantum geometry on the corresponding spheres in AdS/CFT correspondence. These models fit nicely the data from the dipole mechanism for the stringy exclusion principle.

Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Abelian-Higgs and Vortices from ABJM: towards a string realization of AdS/CMT
, 2012 We present ans\"{a}tze that reduce the mass-deformed ABJM model to gauged Abelian scalar theories, using the fuzzy sphere matrices $G^\alpha$. One such reduction gives a Toda system, for which we find a new type of nonabelian vortex.
