Pollution: Associations Persist with Continued Advances in Research Methodology (See Neas et al., p. 629; Lee and Schwartz; p. 633; and Fairley, p. 637) In this issue of Environmental Health Perspectives there are papers by Fairley, Neas et al., and Lee and Schwartz. Although these papers present different approaches, they provide a reasonable representation of stateof-the-art epidemiologic res...

Mobility management is a major challenge for millimeter-wave (mmWave) cellular networks. In particular, directional beamforming in mmWave devices renders high-speed mobility support very complex. This complexity, however, not limited to system design but also the performance estimation and evaluation. Hence, some have turned their attention stochastic modeling of vehicular communication derive ...

Multivariate receptor modeling is used to estimate profiles and contributions of pollution sources from concentrations of pollutants such as particulate matter in the air. The majority of previous approaches to multivariate receptor modeling assume pollution source profiles are constant through time. In an effort to relax this assumption, this article uses the Dirichlet distribution in a dynami...

Vehicular traffic has evolved as a crucial means for the transport of persons and goods, its importance economic social life modern society cannot be overemphasized. On other hand, recurrent vehicular congestion, which appears on daily basis, particularly in metropolitan areas, around globe, been (increasingly) serious, fact threatening, problem that calls drastic solutions. Traffic congestion ...

Vehicular networks (VANETs) are mobile ad hoc networks where vehicles that are near each other can exchange data by using wireless communications. Advances in mobile communication technologies have spurred significant research in the exploitation of these types of networks to develop different kinds of data services for drivers. However, these networks are also highly-dynamic and several data m...

conclusions complications of trauma-related injuries are significant factors affecting the outcome of patients. there has been limited research directly exploring this topic, possibly due to the difficulty of undertaking such studies. a particularly important research topic is the prevention and management of complications in elderly trauma patients with comorbidities. in conclusion, complicati...

the wide availability of data on air pollutant emissions, the knowledge already achieved on theset of chemical and photochemical reactions in the troposphere, the ability to access real time weatherconditions at the local scale that determine the transport and transformation of gases and aerosol, now make it possible to obtain credible and reliable predictions, retrospective analyses and/or fut...

today, the cement industry is one of the major air polluting industries in the world. hence, in this study, owing to the importance and role of contaminants from the plant, an appraisal of the emission contributions in addition to other factors have been discussed. there are several reasons behind the importance of modeling air pollutants. first, the assessment of standards for air pollution, a...

A modeling study using hourly meteorological and pollution concentration data from across the coterminous United States demonstrates that urban trees remove large amounts of air pollution that consequently improve urban air quality. Pollution removal (O3, PM10, NO2, SO2, CO) varied among cities with total annual air pollution removal by US urban trees estimated at 711,000 metric tons ($3.8 bill...
