The aim of this study was to determine the validity of cervical vertebrae radiographic assessment to predict skeletal maturation. Left hand-wrist and lateral cephalometric radiographs of 958 Spanish children from 5 to 18 years of age were measured. On the left hand-wrist radiographs the classification of Grave and Brown was used to assess skeletal maturation. Cervical vertebrae maturation was e...
Today’s networks typically carry or deploy dozens of protocols and mechanisms simultaneously such as MPLS, NAT, ACLs and route redistribution. Even when individual protocols function correctly, failures can arise from the complex interactions of their aggregate, requiring network administrators to be masters of detail. Our goal is to automatically find an important class of failures, regardless...

This paper is a continuation of [MNS], where an analytic smoothing effect was proved for long-range type perturbations of the Laplacian H0 on R . In this paper, we consider short-range type perturbations H of the Laplacian on R, and we characterize the analytic wave front set of the solution to the Schrödinger equation: ef , in terms of that of the free solution: e0f , for t < 0 in the forward ...
A key challenge facing education reformers is how to attract and retain talented people in the teaching profession. Research shows the impact that teacher quality has on student achievement and that our most economically disadvantaged students, those who need the most from their schools, are least likely to have the most qualified teachers. The fact is that while we have many great teachers who...
Halogen bonding is a flourishing field of research, but has for long been little recognized. The same goes its scientific hero, Odd Hassel, who laid the foundations all current developments. crystallographic observation halogen−oxygen interatomic distances shorter than sum van der Waals radii involved atoms, and interpretation this phenomenon as charge-transfer interaction, have ground-breaking...

The fastest tools for network reachability queries use adhoc algorithms to compute all packets from a source S that can reach a destination D. This paper examines whether network reachability can be solved efficiently using existing verification tools. While most verification tools only compute reachability (“Can S reach D?”), we efficiently generalize them to compute all reachable packets. Usi...
crystalline composition of silver islands on Si(111) D. Wall S. Tikhonov S. Sindermann D. Spoddig C. Hassel M. Horn-von Hoegen F.-J. Meyer zu Heringdorf Photoemission electron microscopy and spot profile analyzing low-energy electron diffraction have been used to study the temperature-dependent growth of Ag islands on a Si(111) surface. Depending on growth temperature, various island shapes can...
