A dimer ABC: [PDF]

open access: yesBulletin of the London Mathematical Society, 2016
We give an overview of recent developments in the theory of dimer models. The viewpoint we take is inspired by mirror symmetry. After an introduction to the combinatorics of dimer models, we will first look at dimers in dynamical systems and statistical mechanics, which can be viewed as coming from the A-model in mirror symmetry.

Crystal structure and Hirshfeld surface analysis of 10-hydroxy-2-(4-methoxyphenyl)-3-oxo-2,3,3a,4,10,10a-hexahydro-1H-9-thia-2-azacyclopenta[b]fluorene-4-carboxylic acid dimethyl sulfoxide-d6 monosolvate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2023
In the title compound, C22H19NO5S·C2D6OS, the central six-membered ring has a slightly distorted boat conformation, while the fused pyrrolidine ring adopts an envelope conformation. These conformations are stabilized by O—H...O hydrogen bonds between the

The Early Phase of β2-Microglobulin Aggregation: Perspectives From Molecular Simulations

open access: yesFrontiers in Molecular Biosciences, 2020
Protein β2-microglobulin is the causing agent of two amyloidosis, dialysis related amyloidosis (DRA), affecting the bones and cartilages of individuals with chronic renal failure undergoing long-term hemodialysis, and a systemic amyloidosis, found in one

Two polymorphs of [Rh(μ-I)(COD)]2

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2021
The solid-state structure of di-μ-iodido-bis{[(1,2,5,6-η)-cycloocta-1,4-diene]rhodium(I)}, [Rh2I2(C8H12)2] or [Rh(μ-I)(COD)]2, was determined from two crystals with different morphologies, which were found to correspond to two polymorphs containing Rh ...

Ground state of a tightly bound composite dimer immersed in a Fermi Sea [PDF]

open access: yes, 2009
In this paper we present a theoretical investigation for the ground state of an impurity immersed in a Fermi sea. The molecular regime is considered where a two-body bound state between the impurity and one of the fermions is formed. Both interaction and

On the Low-Lying Electronically Excited States of Azobenzene Dimers: Transition Density Matrix Analysis

open access: yesMolecules, 2021
Azobenzene-containing molecules may associate with each other in systems such as self-assembled monolayers or micelles. The interaction between azobenzene units leads to a formation of exciton states in these molecular assemblies.

Characterization of a Dimeric Arginase From Zymomonas mobilis ZM4

open access: yesFrontiers in Microbiology, 2019
Many organisms have genes to protect themselves from toxic conditions such as high ethanol and/or ammonia concentrations. When a high ethanol condition is induced to Zymomonas mobilis ZM4, a representative ethanologenic organism, this bacterium ...

Bridging the Bridging Imidazolate in the Bimetallic Center of the Cu/Zn SOD1 and ALS

open access: yesFrontiers in Chemistry, 2021
Metallation status of human Cu/Zn superoxide dismutase 1 (SOD1) plays a pivotal role in the pathogenesis of amyotrophic lateral sclerosis (ALS). All of the amino acids found in the bimetallic center have been associated with ALS except for two positions.

Novel banana-discotic hybrid architectures

open access: yesBeilstein Journal of Organic Chemistry, 2009
Here we present the design and synthesis of novel banana-discotic dimers and banana-bridged discotic dimers. The chemical structures have been characterized by spectral techniques and elemental analysis.

The Hepatitis C Virus Nonstructural Protein 2 (NS2): An Up-and-Coming Antiviral Drug Target

open access: yesViruses, 2010
Infection with Hepatitis C Virus (HCV) continues to be a major global health problem. To overcome the limitations of current therapies using interferon-a in combination with ribavirin, there is a need to develop drugs that specifically block viral ...
