Established approaches to design and evaluate usable systems are challenged by systems for wearable, handheld, or mobile devices. There are extensive methods and guidelines that describe how the usability of stationary computer systems should be evaluated [4,6]. This is complemented with experimental evaluations of the relative strengths and weaknesses of different techniques [1,3]. However, in...

MOTIVATION Comparative genomics aims to understand the structure and function of genomes by translating knowledge gained about some genomes to the object of study. Early approaches used pairwise comparisons, but today researchers are attempting to leverage the larger potential of multi-way comparisons. Comparative genomics relies on the structuring of genomes into syntenic blocks: blocks of seq...

During the past few decades, linguists have been striving to investigate language-specific phenomena in addition to their efforts to construct a model of language processing in general. Psycholinguistic studies have been following the same trends by employing a comparative perspective in research on spoken-language processing by human listeners. The aim of this practice is to provide a unified ...

In his well-known paper, Bley-Vroman (1983) discusses the potentially harmful effect of the comparative fallacy, in which " the linguistic description of learners' language may be seriously hindered or sidetracked by a concern with the target language " (p. 2). In order to avoid the problem, he urges researchers to focus on linguistic descriptions of learners' languages with respect to their ow...

The National Cancer Institute (NCI) and the National Toxicology Program (NTP) have carried out a number of laboratory animal carcinogenicity studies and presented the results of these experiments in a series of Technical Reports. This paper tabulates the results of the 327 NCI/NTP studies carried out to date on 308 distinct chemicals, and discusses certain issues relevant to the evaluation of c...

By fractionation of human liver tissue, nuclear, mitochondrial, and connective tissue antigens were prepared. According to the results of serological tests, in conditions associated with substantial damage to the hepatic parenchyma, antibodies reacting with the nuclear and mitochondrial antigens are produced that show practically no reaction with the connective tissue antigen. It is advisable t...

A detailed understanding and monitoring of potential beam loss mechanisms is crucial for every particle accelerator. The main motivation in low energy facilities, such as the Ultra-low energy Storage Ring (USR) at the future Facility of Low energy Antiproton and Ion Research (FLAIR), comes from the very low number of particles available which in such machine ought to be conserved. In high energ...

Proteinpolysaccharides from bovine embryonic rudiments and calf nasal septa were compared by conventional ultracentrifugation in isotonic salt solutions, equilibrium density gradient centrifugation, and free flow electrophoresis. These methods are all suitable for use with large amounts of material and give reliable materials balances. Fractions obtained by any one method could be isolated and ...

Here we provide a brief description of our program to improve diagnostic accuracy in cases with phenotypically similar presentations that are due to distinct histopathologic abnormalities. We propose a staged approach to diagnosis, beginning with a screening assessment of specific, quantitative neuropsychological measures, and followed by assessments of imaging and biofluid biomarkers. Our goal...
