Nonlinear oscillations of the absolute elastic weightless string. Asymptotics construction
Lietuvos Matematikos Rinkinys, 2007 The mathematical model of string nonlinear oscillations is presented. To find the asymptotic solution of the problem an averaging scheme is constructed.

The Main Problem of Lunar Orbit Revisited
The Astronomical Journal, 2023 A novel algorithm based on the Lindstedt–Poincaré method is proposed to construct an analytical solution of the lunar orbit. Based on the analytical solution, a numerical fitting algorithm is proposed to improve the coefficients of the analytical ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Measurement error and statistical disclosure control [PDF]
, 2010 Statistical agencies release microdata to researchers after applying statistical disclosure control (SDC) methods. Noise addition is a perturbative SDC method which is carried out by adding independent random noise to a continuous variable or by ...

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.

Projection Perturbation Methods in Optimization Problems of Controlled Systems
Известия Иркутского государственного университета: Серия "Математика", 2014 Perturbation methods are used to implement the conditions of nonlocal improvement of controls, constructed in the form of special boundary value problems in space of phase and conjugate variables and in the form of special tasks of a fixed point of ...

Secular Evolution of a Two-Planet System of Three Bodies with Variable Masses
UniverseA classical three-body problem with two planets moving around a central star of variable mass on quasi-periodic orbits is considered. The bodies are assumed to attract each other according to Newton’s law of universal gravitation. The star loses its mass

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
