Figure 1: Diagram of SUN 145 (from product instruction manual) Ultrasonic nebulizers (USNs) generate aerosols without changing ventilator volumes or alarms. However, USN output varies with gas flow, is position dependent and generates heat. We wanted to determine whether the AeronebTM Professional Nebulizer System (Aeroneb Pro; Aerogen, Inc., Sunnyvale, CA)* has similar limitations. METHODS: We...

To describe physics properly, we need to take into account quantum effects. Thus, for every nonquantum physical theory, we must come up with an appropriate quantum theory. A traditional approach is to replace all the scalars in the classical description of this theory by the corresponding operators. The problem with the above approach is that due to non-commutativity of the quantum operators, t...

We explain how the usual algebras of Feynman diagrams behave under the grope degree introduced in [CT]. We show that the Kontsevich integral rationally classifies grope cobordisms of knots in 3-space when the “class” is used to organize gropes. This implies that the grope cobordism equivalence relations are highly nontrivial in dimension 3. We also show that the class is not a useful organizing...

Given a point s and a set of h pairwise disjoint polygonal obstacles of totally n vertices in the plane, we present a new algorithm for building an L1 shortest path map of size O(n) in O(T ) time and O(n) space such that for any query point t, the length of the L1 shortest obstacleavoiding path from s to t can be reported in O(log n) time and the actual shortest path can be found in additional ...

We present an algorithm for computing shortest paths and distances from a single generalized source (point, segment, polygonal chain or polygon) to any query point on a possibly non-convex polyhedral surface. The algorithm also handles the case in which polygonal chain or polygon obstacles on the polyhedral surface are allowed. Moreover, it easily extends to the case of several generalized sour...

The middle levels problem is to find a Hamilton cycle in the middle levels, M2k+1, of the Hasse diagram of B2k+1 (the partially ordered set of subsets of a 2k + 1element set ordered by inclusion). Previously, the best known, from [1], was that M2k+1 is Hamiltonian for all positive k through k = 15. In this note we announce that M33 and M35 have Hamilton cycles. The result was achieved by an alg...

In the era of the LHC and in preparation for the ILC there is need for multi-loop calculations to match the precision of these experiments from the theory side. The classes of problems currently accessible reach from multi-leg multi-scale problems at one-loop up to no-scale propagator, and tadpole diagrams at four-loop level. Many problems fall into these categories directly while others can be...

This paper considers a generalization of travel time distances by taking general underlying distance functions into account. We suggest a reasonable set of axioms defining a certain class of distance functions that can be facilitated with transportation networks. It turns out to be able to build an abstract framework for computing shortest path maps and Voronoi diagrams with respect to the indu...

Background: Sun protection materials have been one of the major concerns in pharmaceutical industry since almost one century ago. Various materials have been found to have such an effect but there are still many unknown substances that have not been discovered.Objective: To introduce a novel mineral-based sun lotion with considerable UV absorption properties compared to commercially available s...
