Simulated Dynamical Weakening and Abelian Avalanches in Mean-Field Driven Threshold Models

open access: yes, 2004
Mean-field coupled lattice maps are used to approximate the physics of driven threshold systems with long range interactions. However, they are incapable of modeling specific features of the dynamic instability responsible for generating avalanches. Here

Survivin and Aurora Kinase A control cell fate decisions during mitosis

open access: yesMolecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Assessment of reliability parameters of in-plant power supply schemes with two-transformer substations

open access: yesVestnik MGTU
In the process of designing in-plant power supply systems, it is necessary to determine their rational redundancy. The reliability of the power supply system has been established for the following variants of the circuit of two-transformer 10/0.4 kV ...

METHOD FOR DETERMINING THE MEAN TIME BETWEEN FAILURES OF ESP UNITS

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2022
Electrical submersible pumps are widespread in the oil industry, in particular, for production of watered mixture in periodic pumping mode. Intermittent mode allows reducing energy costs due to application of high-rate equipment with higher efficiency and prompt change of well fluid withdrawal during change of well parameters without changing equipment.

Rapid Recovery for Systems with Scarce Faults

open access: yes, 2012
Our goal is to achieve a high degree of fault tolerance through the control of a safety critical systems. This reduces to solving a game between a malicious environment that injects failures and a controller who tries to establish a correct behavior.

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting

open access: yesMolecular Oncology, EarlyView.
CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and
