Example: "The documents were successfully achieved by post, ensuring they reached the intended recipient on time."
Alternatives: "sent by mail" or "delivered by post".
For instance, high image resolution can be achieved by post-processing an image captured with very simple optics (even a single element).
Exceptional field emission performance has been achieved by post-deposition annealing of the DLC thin films with a TiN transition layer.
An understanding of the relationship between microstructure and damage initiation can often not be achieved by post-mortem microstructural characterization alone.
A further increase in fine porosity was achieved by post-synthesis activation of the carbons with carbon dioxide and/or water vapor, which resulted in hierarchical carbons with a surface area and pore volume approaching 2800 m2/g and 6.0 cm3/g, respectively.
Further, high-performance In2O3 thin-film transistors with an Al2O3 gate dielectric were achieved by post-annealing in air at 300 °C for appropriate time, demonstrating a field-effect mobility of 7.8 cm2/V⋅s, a subthreshold swing of 0.32 V/dec, and an on/off current ratio of 107.
This is especially true for extended profile data where Twitter and Instagram provide only a few additional input fields because self-presentation is achieved by posting items and not by entering static profile information here, and where LinkedIn focuses more on work and science affiliated attributes because of the orientation toward professional networks.
Moreover, most signaling activity is achieved by post-translational modifications of existing proteins such as Notch cleavage, phosphorylation of kinases, or stabilization of proteins such as beta catenin.
Our findings indicate that this target gene selectivity is achieved by post-DNA-binding mechanisms.
Transcriptional regulation of frq is mainly achieved by post-translational regulation of its activator, WCC.
