Auxetic response of additive manufactured cubic chiral lattices at large plastic strains

open access: yesMaterials & Design, 2023
Auxetic lattices exhibit a negative Poisson’s ratio and excellent energy absorption capability. Here, we investigate the compressive performance of auxetic cubic chiral structures.

A robust SNP barcode for typing Mycobacterium tuberculosis complex strains [PDF]

open access: yes, 2014
Strain-specific genomic diversity in the Mycobacterium tuberculosis complex (MTBC) is an important factor in pathogenesis that may affect virulence, transmissibility, host response and emergence of drug resistance.

Mutations identified in engineered Escherichia coli with a reduced genome

open access: yesFrontiers in Microbiology, 2023
Characterizing genes that regulate cell growth and survival in model organisms is important for understanding higher organisms. Construction of strains harboring large deletions in the genome can provide insights into the genetic basis of cell growth ...

Rebuilding the Strain Hardening at a Large Strain in Twinned Au Nanowires [PDF]

open access: yesNanomaterials, 2018
Metallic nanowires usually exhibit ultrahigh strength but low tensile ductility, owing to their limited strain hardening capability. Here, our larger scale molecular dynamics simulations demonstrated that we could rebuild the highly desirable strain hardening behavior at a large strain (0.21 to 0.31) in twinned Au nanowires by changing twin orientation,

On large deformations of thin elasto-plastic shells: Implementation of a finite rotation model for quadrilateral shell element [PDF]

open access: yes, 1997
A large-deformation model for thin shells composed of elasto-plastic material is presented in this work, Formulation of the shell model, equivalent to the two-dimensional Cosserat continuum, is developed from the three-dimensional continuum by employing ...

Computational models for prediction of yeast strain potential for winemaking from phenotypic profiles [PDF]

open access: yes, 2013
Saccharomyces cerevisiae strains from diverse natural habitats harbour a vast amount of phenotypic diversity, driven by interactions between yeast and the respective environment. In grape juice fermentations, strains are exposed to a wide array of biotic

Suppression-subtractive hybridization as a strategy to identify taxon-specific sequences within the Mycoplasma mycoides Cluster: design and validation of an M. capricolum subsp. capricolum-specific PCR assay [PDF]

open access: yes, 2008
The phylogenetically related Mycoplasma capricolum subsp. capricolum and M. mycoides subsp. mycoides biotype Large Colony are two small-ruminant pathogens involved in contagious agalactia. Their respective contributions to clinical outbreaks are not well

Damage-induced changes in elastic stiffness of DP800 sheets at large strains [PDF]

open access: yesMATEC Web of Conferences
Damage is associated with the performance of formed components. Quantifying its influence is challenging due to interactions with other product properties such as strain hardening, texture and residual stresses.
