Experimental Study on Freeze-Thaw Effects on Creep Characteristics of Rubber Concrete

open access: yesAdvances in Materials Science and Engineering, 2022
Crumb Rubber Concrete (CRC) can exhibit high freeze-thaw resistance, but its long-term creep behavior under various freeze-thaw conditions remains unclear, which is essential for the safety of pavement engineering in the severe cold zone.

A Numerical Gear Rolling Test Method for Face-Hobbed Hypoid Gears

open access: yesApplied Sciences, 2023
A numerical gear rolling test (NGRT) method for actual tooth surfaces was proposed. The non-uniform rational B-spline (NURBS) fitting method was adapted to reconstruct the actual tooth surface, and the instant meshing point as well as the transmission ...

Structure of large dsDNA viruses [PDF]

open access: yesBiological Chemistry, 2014
Abstract Nucleocytoplasmic large dsDNA viruses (NCLDVs) encompass an ever-increasing group of large eukaryotic viruses, infecting a wide variety of organisms. The set of core genes shared by all these viruses includes a major capsid protein with a double jelly-roll fold forming an icosahedral capsid, which surrounds a double layer ...

Voids in the Large-Scale Structure [PDF]

open access: yes, 1997
Voids are the most prominent feature of the LSS of the universe. Still, they have been generally ignored in quantitative analysis of it, essentially due to the lack of an objective tool to identify and quantify the voids. To overcome this, we present the

Emergent Structures in Large Networks [PDF]

open access: yesJournal of Applied Probability, 2013
We consider a large class of exponential random graph models and prove the existence of a region of parameter space corresponding to the emergent multipartite structure, separated by a phase transition from a region of disordered graphs. An essential feature is the formalism of graph limits as developed by Lovász et al. for dense random graphs.

Cable Tension Preslack Method Construction Simulation and Engineering Application for a Prestressed Suspended Dome

open access: yesAdvances in Materials Science and Engineering, 2015
To solve the shortage of traditional construction simulation methods for suspended dome structures, based on friction elements, node coupling technology, and local cooling, the cable tension preslack method is proposed in this paper, which is suitable ...

Baryonic Signatures in Large-Scale Structure [PDF]

open access: yes, 1998
We investigate the consequences of a non-negligible baryon fraction for models of structure formation in Cold Dark Matter dominated cosmologies, emphasizing in particular the existence of oscillations in the present-day matter power spectrum.

Design and Model Test of a Modularized Prefabricated Steel Frame Structure with Inclined Braces

open access: yesAdvances in Materials Science and Engineering, 2015
Modularized prefabricated steel structures have become the preferred design in the industrialization of steel structures due to their advantages of fast construction speed, high degree of industrialization, low labour intensity, and more.
