$\kappa$-Deformations and Extended $\kappa$-Minkowski Spacetimes [PDF]

open access: yes, 2014
We extend our previous study of Hopf-algebraic $\kappa$-deformations of all inhomogeneous orthogonal Lie algebras ${\rm iso}(g)$ as written in a tensorial and unified form. Such deformations are determined by a vector $\tau$ which for Lorentzian signature can be taken time-, light- or space-like.

A study in fractional diffusion: Fractured rocks produced through horizontal wells with multiple, hydraulic fractures

open access: yesOil & Gas Science and Technology, 2020
The spatiotemporal evolution of transients in fractured rocks often displays unusual characteristics and is traced to multifaceted origins such as micro-discontinuity in rock properties, rock fragmentation, long-range connectivity and complex flow paths.

Kappa-Chain Deficiency [PDF]

open access: yesBlood, 1972
Abstract A decreased concentration of immunoglobulin molecules of one light chain type (κ) was found in a young girl with recurrent respiratory infections and diarrhea. She had, in addition, decreased γA and γE globulin, partial albinism, and intestinal lactase deficiency.
