Incremental Hamilton's principle with multiple time scales for nonlinear aperiodic vibrations of shells

, 1986
It has been previously provided an extension of the Incremental Harmonic Balance (IHB) Method to aperiodic vibrations of nonlinear systems by introducing the concept of multiple time scales (dimensions), where the solution is assumed to be a combination ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Multiple time scales solution of an equation with quadratic and cubic nonlinearities having fractional-order derivative

, 2011
Nonlinear vibrations of quadratic and cubic system are considered. The equation of motion includes fractional order term. Multiple time scales (a perturbation method) solution of the system is developed.

Multiple time scales in modeling the incidence of infections acquired in intensive care units [PDF]

, 2016
Background When patients are admitted to an intensive care unit (ICU) their risk of getting an infection will be highly depend on the length of stay at-risk in the ICU.

Locally Recurrent Networks With Multiple Time-scales

, 1997
We introduce a new generalized feed-forward structure that provides for multiple time scales. The gamma, Laguerre and other locally recurrent feed-forward structures perform poorly in cases where widely varying time constants are required.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
