Isosurface Stuffing Improved (DRAFT: October 23, 2013)

We present two improvements to Labelle and Shewchuk’s isosurface stuffing algorithm for tetrahedral mesh generation. First, we use an acute tetrahedral lattice known as the A15 lattice in place of the original BCC lattice. In the uniform case, the higher-quality tetrahedra of A15 significantly improve the quality of the resulting mesh; BCC remains the best choice for adaptive meshes, as the A15...

Target frequencies and information content October 23

Given a query sequence, Q, of length m and a database, D, of length n, BLAST attempts to find all maximal segment pairs with statistically significant scores. Recall that a Maximal Segment Pair (MSP) is an ungapped local alignment whose score cannot be improved by extending or shortening the alignment. The data base is a series of concatenated amino acid sequences M1,M2, . . .Mj . . .. Figure 1...

Measurement of the Neutrino Mixing Angle θ_{23} in NOvA.

This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of 6.05×10^{20} protons on target from the NuMI beam at the Fermi National Accelerator Laboratory. The measurement probes the muon-tau symmetry hypothesis that requires maximal θ_{23} mixing (θ_{23}=π/4). Assuming the normal mass hierarchy, we find Δm_{32}^{2}=(2.67±0.11)×10^{-...

A23 23..23

Three papers in the Journal this month examine the impact on service use of particular service developments and patient/illness characteristics. Williams et al (pp. 480–485) compared patterns of service use, including hospital admission rates, before and after the introduction of a triage admission system in one large innercity mental health organisation. Overall, little difference was found be...
