Abstract: A digital instructional environment leverages an infrared eye-tracker to monitor a learner's reading and viewing of text and simulations for subject matter. The system detects out-of-order reading/viewing patterns that could lead to poor comprehension. The digital learning environment communicates with other tutorial components including simulation environments, pedagogical agents and may respond in real-time to such patterns with messages that guide learners (knowledge acquirers) to return to effective reading/viewing patterns so as to promote effective construction of mental model(s) developed during knowledge acquisition/learning.

Abstract: Methods and systems for automatic detection of Atrial Fibrillation (AF) are disclosed. The methods and systems use time-varying coherence functions (TVCF) to detect AF. The TVCF is estimated by the multiplication of two time-varying transfer functions (TVTFs).

Abstract: The invention pertains to the discovery that the presence of oocyte spindle associated factors in an enucleated oocyte improves oocyte quality and subsequently nuclear transfer. In particular, it was discovered that maintaining oocyte spindle factors in the oocyte after enucleation improves oocyte quality for use in nuclear transfer methodology.
