The purpose of this document is to provide a set of guidelines to aid in the secure operation of the Internet. During its history, the Internet has grown significantly and is now quite diverse. Its participants include government institutions and agencies, academic and research institutions, commercial network and electronic mail carriers, non-profit research centers and an increasing array of ...

The Arthritis Foundation and the Centers for Disease Control have recently prepared a "U.S. National Reference Serum" for human antibodies to native DNA. We tested this serum with 13 commercial assays for antibodies to native DNA, to permit comparisons of the values obtained in each test. Titers ranged from 10 to 2560 in Crithidia luciliae immunofluorescence assays. The serum produced 794 int. ...

Apart from adoption strategies, an existing Software Product Line (SPL) implemented using some variability mechanisms can be migrated to use another variability mechanism. In this paper, we present some migration strategies from one SPL implemented with conditional compilation to one using Aspect-Oriented Programming (AOP). The strategies present a variability pattern handled by the first mecha...

It has been generally known that the agent research community provides powerful theories, algorithms and techniques that have got an immense potential for the deployment in various industrial applications. Sadly noted, the number of agent research centers and groups as much as the number of agent researchers by far outnumbers the commercial companies, CTO, and entrepreneurs that have the courag...

The corona charging technique is widely utilized in commercial Si/SiO2 semiconductor device reliability characterization tools and has been used in numerous electron spin resonance (ESR) experiments, by several groups to study defect centers in Si/SiO2 system. A recent ESR study argued that the corona charging approaches are inherently unreliable and invasive. In this work we show that this is ...

We used ferromagnetic artificial pinning centers in superconducting NbTi wires to achieve a large critical current density (Jc) in a magnetic field. Four wires were fabricated that contained nanometer-sized arrays of Ni or Fe pins inside micron-sized filaments of Nb0.36Ti0.64 alloy. A ferromagnetic pin volume of only 2% Ni produced Jc’s ~e.g., 2500 A/mm 2 at 5 T, 4.2 K! that were comparable to ...

Lead is a toxic substance that attacks many different body organs and systems. Unlike other metals such as zinc or iron, lead has no beneficial effects on the body. Lead is a ubiquitous environmental contaminant, largely due to the wide variety of past and present commercial uses. It is one of the best-studied toxic substances. Lead poisoning is considered by the Centers for Disease Control and...
