Background: Since 1997, human-biting ticks submitted to the Department of Defense Human Tick Test Kit Program (HTTKP) of the US Army Public Health Command have been tested for pathogens by PCR. We noted differences in the phenology and infection prevalence among Ixodes scapularis ticks submitted from military installations in different geographic regions. The aim of this study was to characteri...

In the paper I suggested that for many predicates P, the 'P-er than' relation is a strict weak order. Ondrej Majer asks why I assume that, given that I concentrate myself later in the paper on semi-orders. Well, in case the ordering relation can be made more precise by means of measurement phrases, there is no choice but to use a strict weak order. In fact, speaker's intuitions about a relation...

This paper presents the first results of an experimental study concerning the semantic status of borderline cases of vague predicates. Our focus is on the particular case of color predicates (such as ‘yellow’, ‘orange’, ‘blue’, ‘green’), and on the influence of context in the categorization of color shades at the border between two color categories. In an unpublished study, D. Raffman and colle...

During the course of this UROP, I allowed the flock of birds to communicate with programs and services using PVM, and wrote a rudimentary program to capture data from the flock of birds and the mental model positioning system to allow for comparisons. Doing this involved multiple steps. First, getting the flock to work. Currently there are three birds. They are configured according to the Flock...

The polyneuronal innervation of crustacean muscles has been well explored in decapod limbs, both comparatively at the level of entire muscles (Wiersma & Ripley, 1952) and, by means of single motor axon stimulation and microelectrode recording, at the level of single muscle fibres (Fatt & Katz, 1953a, b; Furshpan, 1955; Hoyle & Wiersma, 1958). Experiments of the latter sort have shown that motor...

Temperature-sensitive mutations of bacteriophage TS gene 42 produce diverse effects upon spontaneous mutation rates. G:C+ A:T transition rates are increased, often strongly; frameshift mutation rates are weakly increased; A:T+ G:C transition rates (and perhaps also A:T+ Py:Pu transversion rates) are decreased; and one G: C --f Py: Pu transversion rate is also decreased. These results, together ...

Computational infrastructure for representing persons and citations has been available in R for several years, but has been restructured through enhanced classes "person" and "bibentry" in recent versions of R. The new features include support for the specification of the roles of package authors (e.g. maintainer, author, contributor, translator, etc.) and more flexible formatting/printing tool...

DNA polymerases replicate DNA with high fidelity lab, which demonstrated that single point mutations in the T4 DNA polymerase gene can increase or decrease because of accurate nucleotide incorporation coupled with exonucleolytic proofreading to remove misinmutation rates by 100-fold or more (Drake et al. 1969). Mutational analysis is a powerful method to probe corporated nucleotides. This state...
