We do not assume, however, that broadcasts are reliably delivered. (One might consider providing a reliable datagram broadcast protocol as a layer above IP.) It is quite expensive to guarantee delivery of broadcasts; instead, what we assume is that a host will receive most of the broadcasts that are sent. This is important to avoid excessive use of broadcasts; since every host on the network de...

An expedient synthesis of N-unsubstituted 1,2,3-triazole-4-carboxylates has been demonstrated through [3 + 2] cycloaddition of sodium azide with α-haloacrylates. The process is highly reliable and exhibits an unusually wide scope with respect to α-fluoro-, α-chloro-, α-bromo-, and α-iodoacrylates. The potential of selected 1,2,3-triazole-4-carboxylates in the preparation of 1,5-dihydro-4H-[1,2,...

Promoting quality of life in older age is an internationally recognized priority, requiring valid measurement. We present a short version of the established Older People's Quality of Life questionnaire (OPQOL-brief). The full OPQOL-35 was original in being developed from the perspectives of older people, assessed conceptually, and validated with a population sample using gold-standard psychomet...

AIM This study aimed to determine the reliability and sex and age-level differences of body-sway parameters, based on center of pressure (COP) measurements, during a static upright posture in the elderly and to clarify their body-sway characteristics in comparison with those of young adults. METHODS The subjects were 50 healthy elderly and 50 healthy young adults. They had no evidence or know...

A sensitive, specific and precise procedure for the measurement of serum gentamicin by radioimmunoassay is presented. The method is rapid, convenient, and highly reliable for this very important measurement. Studies designed to evaluate the validity and reproducibility of the assay are presented and discussed.

A sensitive, specific and precise procedure for the measurement of digoxin by radioimmunoassay is presented. The method is rapid, convenient and highly reliable for this very important measurement. Studies designed to evaluate the validity and reproducibility of the assay are presented and discussed.

“That’s where the money is,” reportedly is a statement ascribed to the bank robber Willie Sutton when he was asked why he robbed banks. In the legal arena, there is often analogous reasoning when someone is aggrieved and seeks redress. This is particularly true when an investment in or loans to an entity go sour. After the debacle, generally the only ones around with deep pockets from whom to s...

Objective(s) In the last few years, serum procalcitonin has been proposed as an early marker of infections in neonates, with varying results. In this study, we aimed to investigate the value of procalcitonin, and C- reactive protein in establishing the diagnosis of neonatal sepsis. Materials and Methods Blood samples were collected at admission from 69 neonates with suspected infection (admi...

We study the thermodynamic and structural properties of a simple, one-patch fluid model using the reference hypernetted-chain (RHNC) integral equation and specialized Monte Carlo simulations. In this model, the interacting particles are hard spheres, each of which carries a single identical, arbitrarily oriented and attractive circular patch on its surface; two spheres attract via a simple squa...

Although adaptivity, the ability to adapt, is an important property of complex computing systems, so far little thought has been given to its evaluation. In this paper we propose a framework and methodology for the definition of benefit-based adaptivity metrics. The metrics thus defined allow an informed choice between systems based on their adaptivity to be made. We demonstrate application of ...
