Medium Range Order in High Aluminum Content Amorphous Alloys Measured by Fluctuation Electron Microscopy

open access: yes, 2007
High Al-content metallic amorphous alloys have an unusual devitrification behavior. Upon annealing, alloys made by a rapid quench develop a high density (>1021 m-3) of pure Al nanocrystals.

High Order Fluctuation Splitting Schemes for Hyperbolic Conservation Laws [PDF]

open access: yes, 2007
This thesis presents the construction, the analysis and the verification of a new form of higher than second order fluctuation splitting discretisation for the solution of steady conservation laws on unstructured meshes.

Terrestrial gravity fluctuations [PDF]

open access: yesLiving Reviews in Relativity, 2015
AbstractTerrestrial gravity fluctuations are a target of scientific studies in a variety of fields within geophysics and fundamental-physics experiments involving gravity such as the observation of gravitational waves. In geophysics, these fluctuations are typically considered as signal that carries information about processes such as fault ruptures ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The Impact of Land Use Change on Groundwater Depth in The Groundwater Transition Zone of Merapi Volcano, Yogyakarta, Indonesia

open access: yesIndonesian Journal of Geography
Studies of the impact of land use change on groundwater on the southern slopes of Merapi Volcano tend to be carried out on a macro basis. Micro studies, especially in groundwater transition zones,  have not been previously conducted.

The Effects of Spontaneous Random Activity on Information Transmission in an Auditory Brain Stem Neuron Model

open access: yesEntropy, 2014
This paper presents the effects of spontaneous random activity on information transmission in an auditory brain stem neuron model. In computer simulations, the supra-threshold synaptic current stimuli ascending from auditory nerve fibers (ANFs) were ...

Energetics of quantum vacuum friction. II. Dipole fluctuations and field fluctuations: Dipole fluctuations and field fluctuations [PDF]

open access: yes, 2022
Quantum vacuum friction experienced by an atom, where the only dissipative mechanism is through its interaction with the radiation field, has been studied in our recent paper [Phys. Rev. D 104, 116006 (2021)PRVDAQ2470-001010.1103/PhysRevD.104.116006].

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Fault Diagnosis of Rolling Bearings using Multifractal Detrended Fluctuation Analysis and Mahalanobis Distance Criterion

open access: yes, 2012
Vibrations of a defective rolling bearing often exhibit nonstationary and nonlinear characteristics which are submerged in strong noise and interference components.
