Cold Spring Harbor Perspectives in Biology, 2012 Hedgehog (Hh) proteins constitute one family of a small number of secreted signaling proteins that together regulate multiple aspects of animal development, tissue homeostasis and regeneration. Originally uncovered through genetic analyses in Drosophila, their subsequent discovery in vertebrates has provided a paradigm for the role of morphogens in ...

An Electro-Oculogram (EOG) Sensor’s Ability to Detect Driver Hypovigilance Using Machine Learning
Sensors, 2023 Driving safely is crucial to avoid death, injuries, or financial losses that can be sustained in an accident. Thus, a driver’s physical state should be monitored to prevent accidents, rather than vehicle-based or behavioral measurements, and provide ...

Seminars in Immunology, 2006 Mammalian Toll-like receptors (TLRs) play a critical role in detection of invading pathogens as well as triggering of subsequent inflammatory and immune responses. Each TLR recognizes distinct microbial components and activates different signaling pathways by selective utilization of adaptor molecules.

The Indexical Voice: Communication of Personal States and Traits in Humans and Other Primates
Frontiers in Psychology, 2021 Many studies of primate vocalization have been undertaken to improve our understanding of the evolution of language. Perhaps, for this reason, investigators have focused on calls that were thought to carry symbolic information about the environment. Here
