Computer Simulations of a Twist Bend Nematic (NTB): A Coarse-Grained Simulation of the Phase Behaviour of the Liquid Crystal Dimer CB7CB

open access: yesCrystals, 2023
In recent years, a number of achiral liquid crystal dimer molecules have been shown to exhibit nematic–nematic phase transitions. The lower temperature phase has been identified as the NTB phase, which demonstrates emergent chirality in the spontaneous ...

Strukturalna analiza molekule vode i njena fizikalna svojstva

open access: yesZbornik Radova, 2020
Voda (H2O) je polarni anorganski spoj, koji je na sobnoj temperaturi tekućina bez okusa i mirisa, gotovo bezbojna. Količinski je daleko najzastupljeniji spoj na Zemlji i među rijetkim je tvarima koje na Zemljinoj površini postoje u krutoj, tekućoj i ...

KONTRUKSI PT-Symmetry MULTI DIMER PADA DOMAIN TAK HINGGA

open access: yesJurnal Lebesgue, 2023
Parity-Time Symmetry, or abbreviated as -Symmetry, can be explained as the propagation of an optical beam in two bound waveguides, where one waveguide experiences strengthening and the other waveguide experiences weakening, with each intensity having the

Modelado dinámico del manipulador serial Mitsubishi Movemaster RV-M1 usando SolidWorks

open access: yesRevista UIS Ingenierías, 2016
Se presenta la aplicación del principio energético Lagrange-Euler para obtener el modelo matemático de la dinámica del robot Mitsubishi Movemaster RV-M1. La determinación de la ubicación de los centros de masa de cada eslabón y las matrices de inercia se

Influence of dimer buckling on dimer diffusion: A scanning tunneling microscopy study [PDF]

open access: yes, 2006
The diffusion of Ge dimers along the substrate dimer rows of Ge(001) has been investigated with scanning tunneling microscopy. The jump frequency of on-top Ge dimers along symmetric dimer rows at room temperature is found to be eight times higher than ...

Partition function of periodic isoradial dimer models [PDF]

open access: yes, 2006
Isoradial dimer models were introduced in \cite{Kenyon3} - they consist of dimer models whose underlying graph satisfies a simple geometric condition, and whose weight function is chosen accordingly. In this paper, we prove a conjecture of \cite{Kenyon3},

Derivatives of 10,16-Dihydroxyhexadecanoic Acid Isolated from Tomato (Solanum lycopersicum) as Potential Material for Aliphatic Polyesters

open access: yesMolecules, 2011
The main monomer of tomato cuticle, 10,16-dihydroxyhexadecanoic acid (or 10,16-dihydroxypalmitic acid; 10,16-DHPA), was isolated and used to efficiently synthesize two different monomers (16-hydroxy-10-oxo-hexadecanoic and 7-oxohexa-decanedioic acids) in

Erratum: (2x1)-(1x1) Phase Transition on Ge(001): Dimer Breakup and Surface Roughening [Phys. Rev. Lett. 91, 116102 (2003)] [PDF]

open access: yes, 2003
Using low energy electron microscopy, we have investigated the (2×1)-(1×1) phase transition occurring above 925 K on Ge(001). Dimer breakup has been identified as the physical origin of this transition.

Comparative Geometrical Analysis of Leucine-Rich Repeat Structures in the Nod-Like and Toll-Like Receptors in Vertebrate Innate Immunity

open access: yesBiomolecules, 2015
The NOD-like receptors (NLRs) and Toll-like receptors (TLRs) are pattern recognition receptors that are involved in the innate, pathogen pattern recognition system.

Dimer geometry, amoebae and a vortex dimer model [PDF]

open access: yes, 2016
We present a geometrical approach for studying dimers. We introduce a connection for dimer problems on bipartite and non-bipartite graphs. In the bipartite case the connection is flat but has non-trivial ${\bf Z}_2$ holonomy round certain curves.
