Fully Automatic Expression-Invariant Face Correspondence [PDF]

, 2013
We consider the problem of computing accurate point-to-point correspondences among a set of human face scans with varying expressions. Our fully automatic approach does not require any manually placed markers on the scan. Instead, the approach learns the

Mismatching Expressions: Spatiotemporal and Kinematic Differences in Autistic and Non‐Autistic Facial Expressions

Autism Research, EarlyView.
ABSTRACT Preliminary studies suggest there are differences in the facial expressions produced by autistic and non‐autistic individuals. However, it is unclear what specifically is different, whether such differences remain after controlling for facial morphology and alexithymia, and whether production differences relate to perception differences ...

Shadows of Bonnor black dihole by chaotic lensing

, 2018
We have studied numerically the shadows of Bonnor black dihole through the technique of backward ray-tracing. The presence of magnetic dipole yields non-integrable photon motion, which affects sharply the shadow of the compact object.

Does education policy affect teachers' learning needs? An international comparison of trends in teachers' continuing professional learning needs in secondary schools in Australia, England, Japan and the Netherlands

British Educational Research Journal, EarlyView.
Abstract Education policy changes are believed to influence teachers' continuing professional learning (CPL) needs, but there is limited empirical evidence to support these claims. This lack of deep understanding has significant practical implications. This study used a new circular conceptual framework to analyse teachers' CPL needs. Leveraging public

3D face tracking and multi-scale, spatio-temporal analysis of linguistically significant facial expressions and head positions in ASL [PDF]

, 2014
Essential grammatical information is conveyed in signed languages by clusters of events involving facial expressions and movements of the head and upper body. This poses a significant challenge for computer-based sign language recognition.

Lab‐Scale Continuous Biomanufacturing: A Tool for Process Development With Adaptive Strategies for Capture and Virus Inactivation

Biotechnology and Bioengineering, EarlyView.
Schematic representation of the continuous lab‐scale process. ABSTRACT Monoclonal antibodies (mAbs) are nowadays fundamental in treating a wide range of severe diseases, including cancer, infections, or autoimmune disorders. Due to their high specificity, potent activity, and fewer side effects compared to small molecular drugs, the market for mAbs is ...
