Under certain circumstances, the collision of magnetic monopoles, topologically locked-in regions of false vacuum, leads to topological inflation and the creation of baby universes. The future evolution of initial data represented by the two incoming monopoles may contain a timelike singularity but this need not be the case. We discuss the global structure of the spacetime associated with monop...

Abstract High temperatures and low rainfall consistently constrain reproduction in arid-zone bird species. Understanding the mechanisms underlying this pattern is critical for predicting how climate change will influence population persistence to inform conservation management. In study, we analyzed Southern Pied Babbler Turdoides bicolor nestling survival, daily growth rate adult investment be...

"Therapeutic misconception" has been misconstrued, and some of the newer, mistaken interpretations are troublesome. They exaggerate the distinction between research and treatment revealing problems in the foundations of research ethics and possibly weakening informed consent.

In this paper, we address issues in situated language understanding in a rapidly changing environment – a moving car. Specifically, we propose methods for understanding user queries about specific target buildings in their surroundings. Unlike previous studies on physically situated interactions such as interaction with mobile robots, the task is very sensitive to timing because the spatial rel...
