Improvements in Turbulent Jet Particle Dispersion Modeling and Its Validation with DNS

open access: yesAtmosphere
Particle dispersion models (PDMs) are essential to capture the influence of unresolved turbulent eddies on particle transport in computational fluid dynamics (CFD) simulations.

Reactimeter dispersion equation

open access: yesNuclear Energy and Technology, 2016
The aim of this work is to derive and analyze a reactimeter metrological model in the form of the dispersion equation which connects reactimeter input/output signal dispersions with superimposed random noise at the inlet.

Turbulent dispersion of a passive scalar in a smooth-wall turbulent boundary layer

open access: yesJournal of Fluid Mechanics, 2023
The scalar dispersion of a ground-level point-source plume in a smooth-wall turbulent boundary layer is experimentally investigated using simultaneous particle image velocimetry and planar laser-induced fluorescence techniques. In the near-source region,

On Some Layer‐Based Risk Measures with Applications to Exponential Dispersion Models [PDF]

open access: yesJournal of Probability and Statistics, 2010
Layer‐based counterparts of a number of well‐known risk measures have been proposed and studied. Namely, some motivations and elementary properties have been discussed, and the analytic tractability has been demonstrated by developing closed‐form expressions in the general framework of exponential dispersion models.

Exponential Dispersion accelerated degradation modelling and reliability assessment considering initial value and processes heterogeneity

open access: yesEksploatacja i Niezawodność – Maintenance and Reliability
In the production and operation, inherent variability and uncertainty necessitate addressing unit-to-unit heterogeneity in initial performance values and degradation processes.

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 ...

Ion temperature gradient mode and its solitons with regularized κ-distributed electrons

open access: yesAIP Advances, 2022
The linear and the non-linear behaviors of the ion temperature gradient (ITG) mode in a plasma with regularized κ-distributed electrons are investigated using the fluid model.

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.

Generalized Linear Model (GLM) Applications for the Exponential Dispersion Model Generated by the Landau Distribution

open access: yesMathematics
The exponential dispersion model (EDM) generated by the Landau distribution, denoted by EDM-EVF (exponential variance function), belongs to the Tweedie scale with power infinity. Its density function does not have an explicit form and, as of yet, has not
