We add name groups and group creation to the typed ambient calculus. Group creation is surprisingly interesting: it has the eeect of statically preventing certain communications, and can thus block the accidental or malicious escape of capabilities that is a major concern in practical systems. Moreover, ambient groups allow us to reene our earlier work on type systems for ambient mobility. We p...

We discuss the idea of ambient networking and describe our contribution to this field on providing quality of service in 802.11b wireless LANs, service discovery, and personal communication environments.

Background Asthma is a chronic condition described by inflammation of the airways and lungs. Diesel exhaust (DE) is a major contributor to ambient particulate matter (PM) air pollution. There is rising evidence that PM acts as adjuvant on the immune responses and may lead to augmentation of allergic inflammation [1,2]. We aim to elucidate if DE increases allergen-induced inflammation and cellul...

Non-self-intersection is both a topological and a geometric property. Recent theorems show how non-self-intersecting Bézier curves also have non-self-intersecting control polygons, after sufficiently many uniform subdivisions. As a partial generalization, a sufficient condition is given within R for a non-self-intersecting, C cubic Bézier curve to be ambient isotopic to its control polygon form...

We define ambient isotopy invariants of oriented knots and links using the counting invariants of framed links defined by finite racks. These invariants reduce to the usual quandle counting invariant when the rack in question is a quandle. We are able to further enhance these counting invariants with 2-cocycles from the coloring rack’s second rack cohomology satisfying a new degeneracy conditio...

The objective of this chapter is to examine and obtain a better understanding of practical issues that are a result of monitoring the health of structures in an uncontrolled field environment. The effects of external boundary and environmental condition changes and other structural variations on the impedance-based health monitoring technique are investigated. Examples of the factors that consi...

We propose to bring the power of NGST to bear on one of the most important problems in star formation { understanding protostellar formation from parent molecular cores and subsequent evolution towards becoming young stars. A few extremely young (10 < < 10 yr) protostars have nally been discovered with sub-millimeter telescopes in recent years, but the high extinctions (Av > 400 mag) towards th...

We work in the Polyhedral Category as defined in [3], which consists of polyhedra and polymaps. A polyhedron is a space with a maximal nonempty family of p.l. related triangulations and a polymap is p.l. w.r.t. these triangulations. An ambient isotopy of a polyhedron X is a level-preserving homeo, H: XXI->XXI with H\XXl = l, Ht: X-^X for tEI is the homeo induced by H\XXt. An isotopy of Y in X i...

Atlantic salmon (Salmo salar) parr were exposed in two outdoor experiments, ranging in duration from 52 to 137 days, to spectral treatments: (1) natural sunlight (=present ambient UVB level), (2) solar radiation supplemented with enhanced UVB radiation from lamps simulating 20% or 8% stratospheric ozone loss or (3) UVB-depleted sunlight achieved by screening with Mylar-D film. The growth, condi...
