Social Calls Predict Foraging Success in Big Brown Bats

Animals foraging in the dark are engaged simultaneously in prey pursuit, collision avoidance, and interactions with conspecifics, making efficient nonvisual communication essential. A variety of birds and mammals emit food-associated calls that inform, attract, or repel conspecifics (e.g.,). Big brown bats (Eptesicus fuscus) are insectivorous aerial hawkers that may forage near conspecifics and...

ESA/390 Interpretive-Execution Architecture, Foundation for VM/ESA

The interpretive-execution facility of Enterprise Systems Architecture/390TM (ESA/390TM) provides an instruction for the execution of virtual machines. This instruction, called START INTERPRETIVE EXECUTION (SIE), was initially created for virtualizing either System/370m or 370-XA architectures and was used later for virtualizing ESA/370' and ESA/390 architectures. SIE has evolved to provide cap...

The ESA Ravenscar Benchmark

This article presents ERB, the ESA Ravenscar Benchmark. ERB aims at providing a synthetic benchmark comparing the efficiency of various Ada Ravenscar implementations and the RTEMS C implementation featuring the native threading model. ERB is original compared to existing Ada benchmarks, such as the ACES or the PIWG, not only because it is the first Ada Ravenscar benchmark, but also because it p...

Positioning for Mvs / Esa Sp 5

IBM’s latest hardware facilities (Parallel Transaction Servers and the Coupling Facility) and software (MVS/SP 5 with its new WLM Workload Manager) are exciting and promise to offer relief in the cost of mainframe applications and ease of managing the resources. To gain immediate and valuable use of the new facilities, however, you should start your migration plan early -as in NOW! The speaker,...
