The crystallization of ion beams has recently been established in the rf quadrupole storage ring PALLAS (PAul Laser CooLing Acceleration System) for laser-cooled 24Mg+ ion beams at an energy of about 1 eV. Yet, unexpectedly sharp constraints had to be met concerning the confinement strength and the longitudinal laser cooling rate. In this paper, related and up to now unseen heating mechanisms a...

In this paper we explore the scientific synergies between Athena and some of key multi-messenger facilities that should be operative concurrently with Athena. These include LIGO A+, Advanced Virgo+ future detectors for ground-based observation gravitational waves (GW), LISA space-based observations GW, IceCube KM3NeT neutrino observations, CTA very high energy observations. science themes encom...

People use arguments to justify their claims. Computer systems use explanations to justify their conclusions. User acceptance of a system depends partly on how well the system explains its reasoning and justifies its conclusions. We have built WOZ, an explanation framework that justifies the conclusions of a clinical decision-support system. WOZ’s central component is the explanation strategy t...

The advent of multiplexed bead assays in recent years has introduced a new dimension of testing for complex diseases such as lupus, which can involve multiple autoantibodies. The ability to rapidly identify multiple autoantibodies, with high sensitivity and specificity in an automated fashion, is highly attractive. The aim of this study was to assess the performance and clinical value of multip...

In this article we describe a system we have constructed that provides for automated karyotyping of metaphase spreads. The software system Athena – based upon the Macintosh II computer and a Data Translation's frame grabber – is written entirely in C and consists of approximately 200 Kbytes of executable code. While Athena does not provide (at this time) facilities for automated metaphase findi...

Hesiod, the Athena name server, provides naming for services and data objects in a distributed network environment. More specifically, it replaces databases that heretofore have had to be duplicated on each workstation and timesharing machine (e.g., remote file system information, /etc/printcap, /etc/services, /etc/passwd, /etc/group) and provides a flexible mechanism to supply new information ...

We examined the effects of supplemental food sources on parasitism of turf-infesting white grubs (Coleoptera: Scarabaeidae) by tiphiid wasps (Hymenoptera: Tiphiidae). Survival of spring active Tiphia vernalis Rohwer and late summer active Tiphia pygidialis Allen, parasitoids of Japanese beetle, Popillia japonicaNewman, andmasked chafer,Cyclocephala spp., grubs, respectively, was signiÞcantly in...

With the current popularity of cluster computing, the importance of understanding the capabilities and performance potential of the various network interconnects they use is growing. In this paper, we extend work done by other researchers by presenting the results of a performance analysis of multiple network interconnects running identical applications on identical cluster nodes. Repeated isol...
