Fatigue crack propagation characteristics of rubbery materials under variable amplitude loading

open access: yesResults in Physics, 2018
Fatigue failure is a critical issue frequently encountered by the rubber components in service. In this work fatigue crack propagation experiments with an edge-notched pure shear specimen under variable amplitude loading, which brings effectiveness in ...

An Index for T:wave Pointwise Amplitude Variability Quantification

open access: yes2016 Computing in Cardiology Conference (CinC), 2016
The comparison between the pointwise amplitude of different T-waves provides insight into ventricular repolarization liability. However, T-wave pointwise amplitude variability can be confounded by time-domain variability. We, first, compared two algorithms for removing (warping) time-domain variability, one using the original and another one using a ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

A universal, damage-criterion-independent cycle counting method for multiaxial and variable amplitude fatigue [PDF]

open access: yesMATEC Web of Conferences, 2019
None of the procedures for cycle-counting defined in the ASTM document with designation E1049-85 (Reapproved 2017) [1] are generally applicable to non-proportional, multi-axial Fatigue.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Variable amplitude fatigue crack growth at monotonic large scale yielding experiments on stainless steel 316L

open access: yes, 2013
Fatigue crack growth in stainless steel 316L was investigated for two different variable amplitude block loads in the monotonic large scale yielding load range. The crack tip opening displacement, δ, was controlled in situ based on numerical computations

Research on the vibration test load spectrum for bogie frame-mounted tractor motor based on on-track tests

open access: yes机车电传动, 2023
Ignoring the effects of high-frequency signals and small-amplitude cycles that contribute little to structural fatigue damage, rainflow counting was performed on the vibration load of traction motors to generate a three-dimensional load spectrum.
