The cross section of the process e+e− → ωπ0 → π0π0γ has been measured in the c.m. energy range 920–1380 MeV with the CMD-2 detector. Its energy dependence is well described by the interference of the ρ(770) and ρ(1450) mesons decaying to ωπ. Upper limits for the cross sections of the direct processes e+e− → π0π0γ, ηπ0γ have been set.

Simulation of traffic flow is an effective tool for evaluating alternative roadway designs, particularly in congested urban areas. CORSIM, a traffic simulation model with detailed representation of vehicles and their interactions, was used to study the performance of two alternatives for a freeway reconstruction project in Oklahoma City. The simulation identified problem areas in the two freewa...

This paper focuses on the development of small rapid response reconnaissance unmanned helicopters (1 to 3 kg, electric), for use by the military in urban areas and by civilian first responders, in terms of system architecture, automation (including navigation, flight control, and guidance), and operator interface designs. Design objectives include an effective user interface, a vehicle capable ...

The paper explores a framework combining remote sensing and spatial metrics aimed at improving the analysis and modeling of urban growth and land use change. While remote sensing data have been used in urban modeling and analysis for some time, the proposed combination of remote sensing and spatial metrics for that purpose is quite novel. Starting with a review of recent developments in each of...

We solve the design spectrum problem for all theta graphs with 10, 11, 12, 13, 14 and 15 edges.

A nurse residency program's best practice recommendations are presented within this article and are organized around three processes: establishing the program infrastructure, creating a multistaged evidence-based program, and sustaining the program through appropriate evaluation and dissemination of results. These recommendations represent lessons learned and key findings derived from a team of...

It is a great pleasure for me to attend the Fourth Annual Forum on City Informatization in the Asian-Pacific Region while having this opportunity to exchange views with the distinguished guests. IT Promotes Development, the theme of the annual forum which fully reveals the significance of sustainable development of informatization and its role in the development. This is a theme which attracts ...
