A genetic algorithm to generate maximally orthogonal frames in complex space

open access: yesMachine Learning: Science and Technology
A frame is a generalization of a basis of a vector space to a redundant overspanning set whose vectors are linearly dependent. Frames find applications in signal processing and quantum information theory.

Non-Lorentzian M5-brane theories from holography

open access: yesJournal of High Energy Physics, 2019
M-theory on AdS 7 × S 4 admits a description where the AdS 7 factor is constructed as a timelike Hopf fibration over a non-compact three dimensional complex projective space ℂℙ ˜ 3 $$ {\tilde{\mathrm{\mathbb{CP}}}}^3 $$ [1].

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Complex Hadamard Matrices contained in a Bose–Mesner algebra

open access: yesSpecial Matrices, 2015
Acomplex Hadamard matrix is a square matrix H with complex entries of absolute value 1 satisfying HH* = nI, where * stands for the Hermitian transpose and I is the identity matrix of order n.

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

open access: yesFEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

An explicit expression of generating function for one-loop tensor reduction

open access: yesJournal of High Energy Physics
This work introduces an explicit expression for the generating function for the reduction of an n-gon to an (n – k)-gon. A novel recursive relation of generating function is formulated based on Feynman Parametrization in projective space, involving a ...
