Published in 2017 at "Mathematical Notes"

DOI: 10.1134/s0001434617090036

Abstract: For a broad class of functions f: [0,+∞) → ℝ, we prove that the function f(ρλ(x)) is positive definite on a nontrivial real linear space E if and only if 0 ≤ λ ≤ α(E,… read more here.

Published in 2022 at "Frontiers in Molecular Neuroscience"

DOI: 10.3389/fnmol.2022.1011918

Abstract: WIPI (WD-repeat protein Interacting with PhosphoInositides) are important effectors in autophagy. These proteins bind phosphoinositides and recruit autophagy proteins. In mammals, there are four WIPI proteins: WIPI1, WIPI2, WIPI3 (WDR45B), and WIPI4 (WDR45). These proteins… read more here.
