Nijenhuis Integrability for Killing Tensors

, 2016
The fundamental tool in the classification of orthogonal coordinate systems in which the Hamilton-Jacobi and other prominent equations can be solved by a separation of variables are second order Killing tensors which satisfy the Nijenhuis integrability ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Solitary Wave and Shock Wave Perturbation for the Modified Kawahara Equation

East European Journal of Physics
This paper retrieves shock waves and solitary wave solutions to the modified Kawahara equation in the presence of perturbation terms. The generalized G'/G-expansion approach is the adopted integration methodology for the model.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

The variety of integrable Killing tensors on the 3-sphere [PDF]

, 2013
Integrable Killing tensors are used to classify orthogonal coordinates in which the classical Hamilton–Jacobi equation can be solved by a separation of variables.

Some New Analytical and Numerical Results for the Nuclear Spin Generator (Sherman) System

Mathematics
This work studies the behavior of the nuclear spin generator (NSG) system, also known as the Sherman system. The analysis is carried out analytically and numerically by finding both exact solutions and bifurcations.

Do All Integrable Equations Satisfy Integrability Criteria?

Advances in Difference Equations, 2008
At the price of sacrificing all suspense, we can already announce that the answer to the question of the title is “no.” It is indeed our belief that one may find counterexamples to all integrability conjectures, unless one constrains the ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Newton-Cartan D0 branes from D1 branes and integrability

Journal of High Energy Physics, 2020
We explore analytic integrability criteria for D1 branes probing 4D relativistic background with a null isometry direction. We use both the Kovacic’s algorithm of classical (non)integrability as well as the standard formulation of Lax connections to show
