Fine-tuning problems in quantum field theory and Lorentz invariance: A scalar-fermion model with a physical momentum cutoff

open access: yes, 2017
We study the consistency of having Lorentz invariance as a low energy approximation within the quantum field theory framework. A model with a scalar and a fermion field is used to show how a Lorentz invariance violating high momentum scale, a physical ...

Collapse of loose sand with the addition of fines: the role of particle shape [PDF]

open access: yes, 2012
This paper describes a fundamental study to explore the role of particle shape in the shear behaviour of mixtures of sand and fine particles (fines) through macro-scale and grain-scale laboratory experiments together with interpretations in the framework

Impact of Gap-Graded Soil Geometrical Characteristics on Soil Response to Suffusion

open access: yesGeotechnics
The phenomenon of fine particle migration through the voids of the granule skeleton under the seepage force is called suffusion. Relative density, original fine particle content, and gap ratio are thought to play vital roles in the suffusion process ...

Combustion characteristics of different types of quasi-particles in iron ore sintering process

open access: yes工程科学学报, 2019
The iron ore sintering process is the main source of NOx emissions and accounts for about 48% of the total NOx emissions in the iron and steel industry.

Hot ductility of TiNb IF steel slab after hot torsion testing [PDF]

open access: yes, 2019
The aim of the work was to evaluate the hot ductility loss in TiNb stabilized IF steel directly from the continuously-cast slab using hot torsion testing (plastometry) in the temperature range 600-1250 degrees C according to the basic programme, and also

Properties and Engineering Influence of Corewall Filter I with Different Fine Particle Contents

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract The protection provided by filter I for the corewall constitutes an important safety guarantee for the impervious bodies of corewall dams. In particular, the fine particle content (the content of particles < 0.075 mm in size) of filter I provides a filter protection effect for the corewall.

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.

Research on micro-influence mechanism of fine particles on dynamic characteristics of graded macadam materials in heavy-haul railway subgrade beds

open access: yesCase Studies in Construction Materials, 2023
Fine particle content is an important physical state parameter of graded macadam materials used in heavy-haul railway subgrade beds. Understanding the micro-influence mechanism of the fine particle content on the filler’s dynamical characteristics is of ...

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Analysis of the start-up mechanism of moraine debris flow based on flume test:A case study of the Aierkuran Gully along the Sino-Pakistan highway

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2021
Debris flow caused by moraine soil startingis very common along the Sino-Pakistan Highway, but in previous studies, the characteristics of moraine soil and its influence on the formation of glacier debris flow is lacking.
