Exposure to Particles and Gases in a Shopping Mall: Spatial Heterogeneity and Outdoor Infiltration
Shopping malls in Hong Kong are usually located near major roads. Indoor air quality (IAQ) in these buildings is subject to infiltration of outdoor traffic-related pollutants, such as PM10, PM2.5, CO, and NO2. Furthermore, the existence of indoor sources

Variational principlesvs. Spatial homogeneity
In this paper the homogeneity ansatz is imposed at the level of Einstein's equations and/or at the level of the action. The commutativity of these operations, as far as the resulting equations are concerned, is reinvestigated. The main result obtained is that, when the restrictions imposed by the isometry group are supplemented by the restrictions on ...

Spatial variability of hosts, parasitoids and their interactions across a homogeneous landscape
Species assemblages and their interactions vary through space, generating diversity patterns at different spatial scales. Here, we study the local‐scale spatial variation of a cavity‐nesting bee and wasp community (hosts), their nest associates ...
