THE CONCEPT OF MODERN APPROACHES TO THE LEVELS OF DESCRIBING THE AGING PROCESSES OF STRUCTURALLY AND FUNCTIONALLY COMPLEX CRITICAL SYSTEMS WITH LONG PERIODS OF ACTIVE EXISTENCE

Надежность и качество сложных систем, 2021
Background. Traditional methods for assessing and analyzing the indicators of the durability of equipment of complex systems are based on the description of systems in time at the level of trajectories of behavior, and are idealizations, since they do ...

Twisted Heisenberg chain and the six-vertex model with DWBC

, 2013
In this work we establish a relation between the six-vertex model with Domain Wall Boundary Conditions (DWBC) and the $XXZ$ spin chain with anti-periodic twisted boundaries.

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.

Research on Forced Vibration Model of End Effector Under Low-Frequency Excitation and Vibration-Suppression Technology

Micromachines
The positioning accuracy of the end effector is the core index that affects the robot’s performance. However, to achieve lightweight and functional requirements, the construction of end effectors is becoming more complex.

INCREASING CONTROL’S EFFICIENCY FOR THE SHIP’S TWO-MASS ELECTRIC DRIVE

Electrical engineering & Electromechanics, 2016
Purpose. For shipboard lifting and transporting machinery (LTM) with AC thyristor electric drives (ED) the problem of minimizing sway through the formation of the special law to change the principle of ED control over the lifting process is solved ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Semiquantum Chaos and the Large N Expansion

, 1994
We consider the dynamical system consisting of a quantum degree of freedom $A$ interacting with $N$ quantum oscillators described by the Lagrangian \bq L = {1\over 2}\dot{A}^2 + \sum_{i=1}^{N} \left\{{1\over 2}\dot{x}_i^2 - {1\over 2}( m^2 + e^2 A^2)x_i ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
