An ideal datacenter network should provide several properties, including low median and tail latency, high utilization (throughput), fair allocation of network resources between users or applications, deadline-aware scheduling, and congestion (loss) avoidance. Current datacenter networks inherit the principles that went into the design of the Internet,(More)
A model of quality of life is proposed that integrates objective and subjective indicators, a broad range of life domains, and individual values. It takes account of concerns that externally derived norms should not be applied without reference to individual differences. It also allows for objective comparisons to be made between the situations of(More)
Adapiform or 'adapoid' primates first appear in the fossil record in the earliest Eocene epoch ( approximately 55 million years (Myr) ago), and were common components of Palaeogene primate communities in Europe, Asia and North America. Adapiforms are commonly referred to as the 'lemur-like' primates of the Eocene epoch, and recent phylogenetic analyses have(More)
Analysis of the teeth, orbital, and gnathic regions of the skull, and fragmentary postcranial bones provides evidence for reconstructing a behavioral profile of Amphipithecidae: Pondaungia, Amphipithecus, Myanmarpithecus (late middle Eocene, Myanmar) and Siamopithecus (late Eocene, Thailand). At 5-8 kg, Pondaungia, Amphipithecus, and Siamopithecus are(More)
Active support, a package of procedures which includes activity planning, support planning and training on providing effective assistance, was introduced in five community residences serving 19 adults with severe intellectual disability following a multiple baseline design. The residents were directly observed to ascertain the level of assistance they(More)
A potential 24-item short form (SABS) of the 73-item Adaptive Behavior Scale-Residential and Community (Part I) (ABS-RC2; Nihira et al., 1993a, b) was developed, based on data from two diverse UK samples of adults with intellectual disabilities living in residential services (n = 560 and 254). SABS factor and total scores showed good internal reliability in(More)
BACKGROUND POMONA II was a European Commission public health-funded project. The research questions in this article focus on age-specific differences relating to environmental and lifestyle factors, and the 17 medical conditions measured by the POMONA Checklist of Health Indicators (P15). METHOD The P15 was completed in a cross-sectional design for a(More)
A fundamental problem in wireless networks is to develop communication protocols that achieve high throughput in the face of noise, interference, and fading, all of which vary with time. An ideal solution is a <i>rateless</i> wireless system, in which the sender encodes data without any explicit estimation or adaptation, implicitly adapting to the level of(More)
Paleontological work carried out over the last 3 decades has established that three major primate groups were present in the Eocene of Africa-anthropoids, adapiforms, and advanced strepsirrhines. Here we describe isolated teeth of a previously undocumented primate from the earliest late Eocene ( approximately 37 Ma) of northern Egypt, Nosmips aenigmaticus,(More)
