Can we believe that there are non-existent entities without commitment to Meinongian metaphysics? This paper argues we can. Let’s say we propose that, as appearances suggest, names like Pegasus refer to non-existent things. They are not, in other words, empty names, names without referents. Rather, they are terms that refer, and so have referents, but the referents do not exist. Moreover, at le...

Many applications generate very large data sets that are too massive for effective manipulation using conventional main memory techniques. One specific application area associated with DNA (DeoxyriboNucleic Acid) research, is the log that tracks samples through the analysis process. Analyses of this kind can easily produce 10,000,000 records in a short time period. Tracking a single sample thro...

Heterogeneous multi-cores—platforms comprised of both general purpose and accelerator cores—are becoming increasingly common. While applications wish to freely utilize all cores present on such platforms, operating systems continue to view accelerators as specialized devices. The Pegasus system described in this paper uses an alternative approach that offers a uniform resource usage model for a...

Our research focuses on creating and executing large-scale scientific workflows that often involve thousands of computations over distributed, shared resources. We describe an approach to workflow creation and refinement that uses semantic representations to 1) describe complex scientific applications in a data-independent manner, 2) automatically generate workflows of computations for given da...

Abstract Our last emerging trend article introduced Risks 1.0 (fairness and bias) 2.0 (addictive, dangerous, deadly, insanely profitable). This introduces 3.0 (spyware cyber weapons). are less profitable, but more destructive. We will summarize two recent books, Pegasus: How a Spy in Your Pocket Threatens the End of Privacy, Dignity, Democracy is They Tell Me World Ends: The Cyberweapons Arms R...

Abstract We report the discovery of Pegasus IV, an ultra-faint dwarf galaxy found in archival data from Dark Energy Camera processed by DECam Local Volume Exploration Survey. IV is a compact, stellar system ( r 1 <mm...

ABSTRACT We report the discovery of an ultrafaint dwarf in constellation Pegasus. Pegasus V (Peg V)/Andromeda XXXIV was initially identified public imaging data release DESI Legacy Imaging Surveys and confirmed with deep from Gemini/GMOS-N. The colour–magnitude diagram shows a sparse red giant branch (RGB) population strong overdensity blue horizontal stars. measure distance to Peg $D=692^{+33}...
