Arrays with Local Centers of Symmetry in Space Groups Pca2_1 and Pna2_1 [PDF]

open access: yes, 1998
Of the several hundred structures in the Cambridge Structural Database [version 4.6 (1992), Cambridge Crystallographic Data Centre, 12 Union Road, Cambridge, England] having space groups Pca2_1 or Pna2_1 and more than one molecule in the asymmetric unit (

Structure-based discovery of fiber-binding compounds that reduce the cytotoxicity of amyloid beta. [PDF]

open access: yes, 2013
Amyloid protein aggregates are associated with dozens of devastating diseases including Alzheimer's, Parkinson's, ALS, and diabetes type 2. While structure-based discovery of compounds has been effective in combating numerous infectious and metabolic ...

Evaluation of machine-learning methods for ligand-based virtual screening [PDF]

open access: yes, 2007
Machine-learning methods can be used for virtual screening by analysing the structural characteristics of molecules of known (in)activity, and we here discuss the use of kernel discrimination and naive Bayesian classifier (NBC) methods for this purpose ...

Close-packing transitions in clusters of Lennard-Jones spheres [PDF]

open access: yes, 2005
The structures of clusters of spherical and homogeneous particles are investigated using a combination of global optimization methods. The pairwise potential between particles is integrated exactly from elementary Lennard-Jones interactions, and the use ...

Structural Classification of Metal Complexes with Three-Coordinate Centres [PDF]

open access: yes, 2015
Attempts to describe the geometry about three-coordinate silver(I) complexes have proven difficult because interatomic angles generally vary wildly and there is no adequate or readily available classification system found in the literature.

Tetrel Bonding Interactions in Perchlorinated Cyclopenta- and Cyclohexatetrelanes: A Combined DFT and CSD Study

open access: yesMolecules, 2018
In this manuscript, we combined DFT calculations (PBE0-D3/def2-TZVP level of theory) and a Cambridge Structural Database (CSD) survey to evaluate the ability of perchlorinated cyclopenta- and cyclohexatetrelanes in establishing tetrel bonding ...

A bibliometric analysis of the Journal of Molecular Graphics and Modelling [PDF]

open access: yes, 2007
This paper reviews the articles published in Volumes 2-24 of the Journal of Molecular Graphics and Modelling (formerly the Journal of Molecular Graphics), focusing on the changes that have occurred in the subject over the years, and on the most ...

The Chirality Chain in Valine: How the Configuration at the Cα Position through the OcisC′CαN Torsional System Leads to Distortion of the Planar Group CαC′(Ocis)Otrans to a Flat Tetrahedron

open access: yesChemistryOpen, 2018
Solid‐state structures, based on a Cambridge Structural Database (CSD) search, show that there is a CαN/C′Ocis attraction in the torsional system OcisC′CαN of valine, causing a chirality chain.

A statistical multiresolution approach for face recognition using structural hidden Markov models [PDF]

open access: yes, 2007
This paper introduces a novel methodology that combines the multiresolution feature of the discrete wavelet transform (DWT) with the local interactions of the facial structures expressed through the structural hidden Markov model (SHMM).
