Eastward traverse of equatorial plasma plumes observed with the Equatorial Atmosphere Radar in Indonesia [PDF]
Annales Geophysicae, 2006 The zonal structure of radar backscatter plumes associated with Equatorial Spread F (ESF), probably modulated by atmospheric gravity waves, has been investigated with the Equatorial Atmosphere Radar (EAR) in West Sumatra, Indonesia (0.20°

Structural Concrete, EarlyView.Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

Journal of Animal Ecology, EarlyView.We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...
