Nonlinear Vibration Analysis of Turbocharger Rotor Supported on Rolling Bearing by Modified Incremental Harmonic Balance Method

Machines
High-speed rolling bearings exhibit low friction, high mechanical efficiency, low lubrication requirements, and excellent acceleration performance. The replacement of floating ring bearings in turbochargers with rolling bearings is an important tendency ...

Factorization of Nonlinear Systems [PDF]

, 1989
Summary: A basic result of \textit{H. Bart}, \textit{I. Gohberg} and \textit{M. A. Kaashoek} [Minimal factorization of matrix and operator functions (1979; Zbl 0424.47001)] parametrizes factorizations of the transfer function of a linear system in terms of the state space equations of the system. This paper extends their result to nonlinear systems.

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

FEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

Integral sliding mode control for non-linear systems with mismatched uncertainty based on quadratic sliding mode

The Journal of Engineering, 2015
In this study, uncertainty and disturbance compensations are addressed for non-linear systems by an integral sliding mode (ISM) design. It is divided into two steps for implementation of the ISM control.

The equivalent nonlinearity for a nonlinear system with dither

Journal of Mathematical Analysis and Applications, 1973
AbstractGiven a single loop nonlinear control system. The problem of constructing a dither signal in order to obtain a desired equivalent nonlinearity is considered. It is assumed that the nonlinearity may be described by a kth order polynomial. For this case it is shown that in general k different levels for the dither signal are necessary.

Interaction of class III cellobiose dehydrogenase with lytic polysaccharide monooxygenase

FEBS Open Bio, EarlyView.
The activity of lytic polysaccharide monooxygenase (LPMO) is supported by its auxiliary enzyme cellobiose dehydrogenase (CDH). The catalytic activity of both enzymes is coupled by electron transfer and a cyclic cascade generating substrates for both enzymes – hydrogen peroxide for LPMO and oxidized and non‐oxidized cellobiose and cello‐oligosaccharide ...

Performance of Composite Endpoints Defining Progression Independent of Relapse Activity in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The characteristics and utility of composite progression independent of relapse activity (cPIRA; worsening on the Expanded Disability Status Scale [EDSS], or 9‐Hole Peg Test, or Timed 25‐Foot Walk Test) were evaluated as an endpoint in relapsing multiple sclerosis (RMS) trials using the ENSEMBLE (NCT03085810) and pooled OPERA I/II ...

The effects of nonlinear couplings and external magnetic field on the thermal entanglement in a two-spin-qutrit system

, 2005
We investigate the effects of nonlinear couplings and external magnetic field on the thermal entanglement in a two-spin-qutrit system by applying the concept of negativity. It is found that the nonlinear couplings favor the thermal entanglement creating.

The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,
