Assuming string theorists will not soon provide a compelling case for the primary theory underlying particle physics, the field will proceed as it has historically: with data stimulating and testing ideas. Ideally the soft supersymmetry breaking Lagrangian will be measured and its patterns will point to the underlying theory. But there are two new problems. First a matter of principle: the theo...

Incomplete cusp edges model the behavior of the Weil-Petersson metric on the compactified Riemann moduli space near the interior of a divisor. Assuming such a space is Witt, we construct a fundamental solution to the heat equation, and using a precise description of its asymptotic behavior at the singular set, we prove that the Hodge-Laplacian on differential forms is essentially self-adjoint, ...

Patients with chronic itch are diagnosed and treated by dermatologists. However, itch is a neural sensation and some forms of chronic itch are the presenting symptoms of neurological diseases. Dermatologists need some familiarity with the most common neuropathic itch syndromes to initiate diagnostic testing and to know when to refer to a neurologist. This review summarizes current knowledge, ad...

Billings (1996) and other researchers (e.g., Vakil, Hansman, Midkiff, & Vaneck, 1995) have concluded that pilot models of flight automation systems are incomplete and that these models cause operation and training problems (e.g., Mangold & Eldredge, 1995). Sherry and Polson (in preparation) describe a complete model of the avionics. This report summarizes that model and its application to the d...

This paper presents a language for coordinating several logic-based agents capable of abductive reasoning. The system is particularly suited for solving problems with incomplete knowledge, where agents may need to make reasonable hypotheses about the domain. We defined a simple declarative language to express agent behavior, and in particular, two forms of coordination: collaboration and compet...

Possible models of the structure of the influenza virus envelope are considered in terms of the known chemical composition. Models incorporating lipid in the form of a bimolecular leaflet are shown to be unlikely on geometrical grounds. A model having "inverted toadstool" protein units separated by spherical lipid micelles is favored, and is capable of explaining the appearance of the virus in ...

Infantile cortical hyperosteosis (ICH) is usually a self-limited disease of infancy with bony changes, soft tissue swelling, fever, irritability, decreased appetite, and decreased movement of the affected bones. Its description in isolated patients or in multiple members of families suggests the existence of two different forms, namely a sporadic form and a familial form with incomplete penetra...
