Marker-free GPU-based digital image correlation system for high-temperature strain-controlled fatigue measurements [PDF]
, 2017 In contrast to tactile extensometers 2D digital image correlation (2D-DIC) works contactless and thus without slip. It measures not only the average strain between two points, it also allows for full-field analysis, e.g.

Optimized Patterns for Digital Image Correlation [PDF]
, 2012 This work presents theoretical background on a novel class of strain sensor patterns. A combination of morphological image processing and Fourier analysis is used to characterize gray-scale images, according to specific criteria, and to synthesize patterns that score particularly well on these criteria.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...
