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 ...

Relativistic Zel'dovich approximation in spherically symmetric model [PDF]
, 1997 We compare relativistic approximation methods, which describe gravitational instability in the expanding universe, in a spherically symmetric model. Linear perturbation theory, second-order perturbation theory, relativistic Zel'dovich approximation, and ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Static Perturbation Analysis of Inclined Shallow Elastic Cables under general 3D-loads
Curved and Layered Structures, 2016 Inclined, shallow, elastic cables under static 3D loads, arbitrarily distributed, are studied. Cables having natural length both larger or smaller than the distance between the supports (i.e.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

An Orbit-flip Mechanism by Eccentric Lidov–Kozai Effect with Stellar Oblateness
The Astronomical Journal, 2023 Orbit flips have been previously found under the eccentric Lidov–Kozai effect (ELK) in hierarchical three-body systems. Recently, we have found that, in certain conditions, the orbit can flip its orientation in a much different manner, where the stellar ...

The quantum Neumann model: asymptotic analysis [PDF]
, 2005 We use semi--classical and perturbation methods to establish the quantum theory of the Neumann model, and explain the features observed in previous numerical computations.Comment: 14 pages, 3 ...
