Development of an Optimization-Based Atomistic-to-Continuum Coupling Method

, 2013
Atomistic-to-Continuum (AtC) coupling methods are a novel means of computing the properties of a discrete crystal structure, such as those containing defects, that combine the accuracy of an atomistic (fully discrete) model with the efficiency of a ...

Numerical determination of entanglement entropy for a sphere

, 2009
We apply Srednicki's regularization to extract the logarithmic term in the entanglement entropy produced by tracing out a real, massless, scalar field inside a three dimensional sphere in 3+1 flat spacetime.

OPTIMIZING 3D PRINTING PARAMETERS TO IMPROVE DIMENSIONAL ACCURACY

ENVIRONMENT. TECHNOLOGIES. RESOURCES. Proceedings of the International Scientific and Practical Conference
The article examines the influence of 3D printing speed and layer thickness on the accuracy of  functional dimensions of a part-eight wall prism with 5 holes-one in the centre and 4 in the periphery. For printing the samples, ABS material was used, which is one of the main materials for the production of  machines and parts.

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights from a large international sicca registry

Arthritis Care &Research, Accepted Article.
Purpose The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögrens International Collaborative Clinical Alliance (SICCA) cohort. Methods Retrospective analysis examining 16 ocular symptoms (most graded 0‐4) and artificial tear (AT) use (graded 0‐3) as predictors of DED signs [abnormal ocular surface staining ...
