The visual nature of geometry applications makes them a natural area where visualization can be an effective tool for demonstrating algorithms. In this paper we propose a new model, called Mocha, for interactive visualization of algorithms over the World Wide Web. Mocha is a distributed model with a client-server architecture that optimally partitions the software components of a typical algori...

This paper presents an integrative approach to understanding of the inner experience of suicidal persons in terms of hemispheric asymmetry. The right hemisphere is involved in formation of polysemantic context. Polysemantic context is determined by multiple interconnections among its elements, while each concrete element bears the stamp of the whole context. Left hemisphere functioning leads to...

Characterizing the resistances to O2 transport from the erythrocyte to the mitochondrion is important to understanding potential transport limitations. A mathematical model is developed to accurately determine the e€ects of erythrocyte spacing (hematocrit), velocity, and capillary radius on the mass transfer coecient. Parameters of the hamster cheek pouch retractor muscle are used in the calcu...

This article examines the performance of 85 UK unit trusts with North American investment objectives between January 1985 and December 1996 using unconditional and conditional performance measures. The paper finds that, on average, the trusts register insignificant performance to each of the respective benchmark portfolios. In addition there is no evidence of any predictability in performance. ...

Objective: In a prospective non-randomized study, we tested the hypothesis that unilateral reduction pneumoplasty followed by completion of bilateral treatment at the reappearance of symptoms might result in more sustained improvements and better survival than one-stage bilateral treatment. Method: Fifty-nine patients undergoing bilateral thoracoscopic reduction pneumoplasty as a one-stage (n 1...

PVC has been under intense and hostile attack for a number of years, primarily because of its association with chlorine chemistry. It has been argued by some that because of this association it is inherently unsustainable, although much of this argument has been emotionally driven rather than based upon scientific scrutiny. Yet the presence of chlorine imparts a range of unique technical featur...

Objectives: The effects of trehalose on cariogenesis by mutans streptococci were investigated. Methods: Inhibited effect of trehalose on water-insoluble glucan (WIG) synthesis from sucrose by glucosyltransferase (GTase) of mutans streptococci was assayed. The acid fermentability of trehalose by mutans streptococci was determined by the measurements of pH, and amounts of lactic acid production. ...

Aims. We present V and R photometry of the gravitationally lensed quasars WFI 2033-4723 and HE 0047-1756. The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope at the ESO La Silla observatory from 2008 to 2012. Methods. Differential photometry has been carried out using the image subtraction method as implemented in the HOTPAnTS package, additionally using GALFIT fo...

Shewanella loihica strain PV-4 harbors both a functional denitrification (NO3 (-)→N2) and a respiratory ammonification (NO3 (-)→NH4 (+)) pathway. Batch and chemostat experiments revealed that NO2 (-) affects pathway selection and the formation of reduced products. Strain PV-4 cells grown with NO2 (-) as the sole electron acceptor produced exclusively NH4 (+). With NO3 (-) as the electron accept...

We present the optical spectra of four newly discovered gravitational lenses from the Cosmic Lens All-Sky Survey (CLASS). These observations were carried out using the Low Resolution Imaging Spectrograph on the W. M. Keck-I Telescope as part of a program to study galaxy-scale gravitational lenses. From our spectra we found the redshift of the background source in CLASS B0128+437 (zs = 3.1240± 0...
