Fractal Dynamics and Control of the Fractional Potts Model on Diamond-Like Hierarchical Lattices

Discrete Dynamics in Nature and Society, 2020
The fractional Potts model on diamond-like hierarchical lattices is introduced in this manuscript, which is a fractional rational system in the complex plane. Then, the fractal dynamics of this model is discussed from the fractal viewpoint.

Development of Fractional Order Modeling of Voltage Source Converters

IEEE Access, 2020
This paper proposes a mathematical fractional order modelling of Voltage Source Converters (VSC). Fractional behaviour helps to model and describe a real object more accurately than the integer order model.

Applications of density matrix in the fractional quantum mechanics

, 2010
The many-body space fractional quantum system is studied using the density matrix method. We give the new results of the Thomas-Fermi model, and obtain the quantum pressure of the free electron gas.

Fractional dynamics pharmacokinetics–pharmacodynamic models [PDF]

Journal of Pharmacokinetics and Pharmacodynamics, 2010
While an increasing number of fractional order integrals and differential equations applications have been reported in the physics, signal processing, engineering and bioengineering literatures, little attention has been paid to this class of models in the pharmacokinetics-pharmacodynamic (PKPD) literature.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Приложение дробной модели деформационной активности к исследованию свойств эредитарности и нестационарности сейсмического процесса в зоне субдукции Курило-Камчатской островной дуги в фазе релаксации

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Исследование свойств эредитарности и нестационарности сейсмического процесса в фазе релаксации проводится на основании данных каталога землетрясений КФ ЕГС РАН (01.01.1962 − 31.12.2002, зона субдукции Курило-Камчатской островной дуги).

Research on Population Development Trend in Huizhou of China Forecast Based on Optimal Weighted Combination Method and Fractional Grey Model

Journal of Mathematics, 2021
In this paper, the optimal weighted combination model and fractional grey model are constructed. The coefficients of the optimal weighted combination model are determined by minimizing the sum of squares of resists of each model.

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.

Предвестники землетрясений в теории критичности геодеформаций

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Предвестники землетрясений рассматриваются как резонансные проявления критических геодеформаций, дислокационные изменения которых отвечают за аномальные свойства, как самих деформаций, так и порожденных ими физических процессов, играющих роль индикаторов

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

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.
