Cortical bone remodeling is carried out by basic multicellular units (BMUs), which couple resorption to formation. Although fluorochrome labeling has facilitated study of BMU formative parameters since the 1960s, some resorptive parameters, including

Objective: X-ray phase contrast imaging generates contrast from refraction of X-rays, enhancing soft tissue contrast compared to conventional absorption-based imaging. Our goal is to develop a contrast agent for X-ray in-line phase contrast imaging (

Some communitarians about personhood hold that human communities are metaphysically antecedent to individual persons, and that personhood comes in degrees, and that one becomes a person through ethical maturation within a community. I offer a new com
