Opening the air‐chamber of an oscillating water column spar buoy wave energy converter to avoid parametric resonance

open access: yesIET Renewable Power Generation, 2021
The oscillating‐water‐column (OWC) spar‐buoy is a type of wave energy converter that may exhibit undesirable large roll and pitch amplitudes caused by a dynamic instability induced by parametric resonance.

Parametric and Autoparametric Resonance

open access: yesActa Applicandae Mathematica, 2002
The author explains the linear and nonlinear dynamics of parametric systems by applying normal form techniques and bifurcation results. Illustrations in rotor dynamics, autoparametric resonance of a parametric oscillator and autoparametric resonance of a self-excited oscillator are provided showing the role of bifurcation, symmetry and attraction to ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Parametric resonances and resonant delocalisation in quasi-phase matched photon-pair generation and quantum frequency conversion

open access: yesNew Journal of Physics, 2019
The existing widely-accepted theory of photon-pair generation via spontaneous down-conversion (SPDC) in nonlinear optical crystals and waveguides is incomplete, as it fails to account for the important physical phenomenon of parametric resonances.

Parametric resonance in metallic bellows connected to pipe due to seismic excitation

open access: yesNihon Kikai Gakkai ronbunshu, 2015
This paper discusses the parametric resonance of the metallic bellows which is connected to the fluid filled pipe subjected to the seismic excitation. The axial stiffness of the metallic bellows varies due to the internal fluid pressure variation, and ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Numerical Study of Resonant Optical Parametric Amplification via Gain Factor Optimization in Dispersive Microresonators

open access: yesPhotonics, 2019
The achievement of wideband high-gain optical parametric amplification has not been shown in micrometer-scale cavities. In this paper we have computationally investigated the optical parametric amplification process in a few micrometer-long dispersive ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.
