FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Hopf bifurcation near a double singular point [PDF]
, 1997 The nonlinear equation f(x,λ,α) = 0, f:X × R2→X, where X is a Banach space and f satisfies a Z2-symmetry relation is considered. Interest centres on a certain type of double singular point, where the solution x is symmetric and fx has a double zero ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The motion of point particles in curved spacetime [PDF]
, 2011 This review is concerned with the motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime. In each of the three cases the particle produces a field that behaves as outgoing radiation in the wave zone,

Moving Singular Points and the Van der Pol Equation, as Well as the Uniqueness of Its Solution
Mathematics, 2023 The article considers the Van der Pol equation nonlinearity aspect related to a moving singular point. The fact of the existence of moving singular points and the uniqueness of their solution for complex domains have been proved.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Constraint preconditioners for solving singular saddle point problems [PDF]
, 2013 We study constraint preconditioners for solving singular saddle point problems. We analyze properties of the preconditioned matrices, in particular their eigenvalue distributions, and prove that for solving singular saddle point problems by ...

Properties of the resolvent of singular q-Dirac operators
Electronic Journal of Differential Equations, 2020 In this article, we investigate the resolvent operator of a singular q-Dirac system. We obtain an integral representations for the resolvent of this system, in terms of the spectral function.

The “paradoxical” mechanism of P. L. Chebyshev [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThe kinematics and dynamics of P. L. Chebyshev's “paradoxical” mechanism are considered. The point of interest in the dynamics of the “paradoxical” mechanism is connected with the fact that its configuration space ...
