Breaking Boundaries

Somitogenesis Breaking New Boundaries

Segmentation is a fundamental process in vertebrate embryogenesis, and one of the earliest manifestations of segmental patterning is the generation of transient, serially repeated blocks of mesodermal cells known as somites. Disruption of the normal segmentation process in humans leads to vertebral abnormalities such as spondylocostal dysostosis. In this minireview, we discuss recent advances i...

Symmetry Breaking Boundaries I. General Theory

We study conformally invariant boundary conditions that break part of the bulk symmetries. A general theory is developped for those boundary conditions for which the preserved subalgebra is the fixed algebra under an abelian orbifold group. We explicitly construct the boundary states and reflection coefficients as well as the annulus amplitudes. Integrality of the annulus coefficients is proven...

Breaking Boundaries in Neural-Immune Interactions

For the past 60 years, the central nervous system has been considered immunologically privileged. Yet results from diverse fields show clear and convincing evidence of bidirectional communication between the nervous and immune systems.

Breaking Boundaries: Mentoring with Wearable Computing

With over 13.3 million children living below poverty line in the United States, there is a pressing need for engaging HCI research with children at the socio-economic margins. Drawing from design studio culture and art therapy literature, we explore wearable computing as a creative and tangible medium (similar to markers, paints, clays, etc.) for motivating ‘at-risk’ children in hands-on making...
