We consider the problem of providingcommunication protocol support for large-scale group collaboration systems for use in environments such as the Internet which are subject to packet loss, wide variations in end-to-end delays, and transient partitions. We identify a set of requirements that are critical for the design of such group collaboration systems. We present a communication service, Cor...

Tropical rainforest clearing and degradation significantly reduces carbon sequestration and increases the rate of biodiversity loss. There has been a concerted international effort to develop remote sensing techniques to monitor broad-scale patterns of forest canopy disturbance. In addition to loss of natural resources, recent deforestation in Mesoamerica threatens historic cultural resources t...

Response : We have replaced the following part of the abstract “A description of the different instruments deployed during the field campaign as well as the available datasets is given first. Examples of concurrent observations from radio frequency to acoustic for regular and atypical lightning flashes are then presented showing a∼rather comprehensive description of lightning flashes available ...

Abstract Recent work published by Lindsey et al. find evidence for a deep and compact seismic source the sunquake associated with 2011 July 30 M9.3 flare, as well emission extending up to 10 mHz. We examine independently, possible wave front is found in 8 mHz band, though no easily discernible band. Additionally, we perform numerical simulations of excitation modeled reported parameters changes...
