The Chromatic Number of the Disjointness Graph of the Double Chain [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
Let $P$ be a set of $n\geq 4$ points in general position in the plane. Consider all the closed straight line segments with both endpoints in $P$. Suppose that these segments are colored with the rule that disjoint segments receive different colors.

Anomalous thermal expansion in 1D transition-metal cyanides: what makes the novel trimetallic cyanide Cu1/3Ag1/3Au1/3CN behave differently? [PDF]

open access: yes, 2019
The structural dynamics of a quasi-one-dimensional (1D) mixed-metal cyanide, Cu1/3Ag1/3Au1/3CN, with intriguing thermal properties is explored. All the current known related compounds with straight-chain structures, such as group 11 cyanides CuCN, AgCN ...

Experimental Study on Hydrodynamic Characteristics of Barge-Type Breakwaters under Different Mooring Methods

open access: yesJournal of Marine Science and Engineering, 2023
In this paper, a yacht project in Tingjiang Town, Mawei, Fujian, is suggested as an example of a barge type breakwater made out of scrap barges. The physical modelling of a two-dimensional flume wave test was carried out on a barge-type breakwater ...

Capacitively coupled Josephson-junction chains: straight versus slanted coupling [PDF]

open access: yesJournal of Physics: Condensed Matter, 2000
Two chains of ultrasmall Josephson junctions, coupled capacitively with each other in the two different ways, straight and slanted coupling, are considered. As the coupling capacitance increases, regardless of the coupling scheme, the transport of particle-hole pairs in the system is found to drive the quantum-phase transition at zero temperature ...

End-to-end distance vector distribution with fixed end orientations for the wormlike chain model [PDF]

open access: yes, 2005
We find exact expressions for the end-to-end distance vector distribution function with fixed end orientations for the wormlike chain model. This function in Fourier-Laplace space adopts the form of infinite continued fractions, which emerges upon ...

Crack initiation characteristics of ring chain of heavy-duty scraper conveyor under time-varying loads

open access: yesAdvances in Mechanical Engineering, 2019
Crack initiation characteristics of ring chain of heavy-duty scraper conveyor under time-varying loads were investigated in this study. The dynamic tension of ring chain of the heavy-duty scraper conveyor was obtained using the time-varying dynamic ...

Novel Mesoporous Silica Materials with Hierarchically Ordered Nanochannel: Synthesis with the Assistance of Straight-Chain Alkanes and Application

open access: yesJournal of Chemistry, 2016
The straight-chain alkane-assisted synthesis of hierarchical mesoporous silica materials (MSM) results in variable mesostructures and morphologies due to remarkably different self-assembly routes of template agent from those without the assistance of ...
