    Dynamics of crystalline acetanilide: Analysis using neutron scattering and computer simulation (1995)

    Notes: The unusual temperature dependence of several optical spectroscopic vibrational bands in crystalline acetanilide has been interpreted as providing evidence for dynamic localization. Here we examine the vibrational dynamics of crystalline acetanilide over a spectral range of ∼20–4000 cm−1 using incoherent neutron scattering experiments, phonon normal mode calculations and molecular dynamics simulations. A molecular mechanics energy function is parametrized and used to perform the normal mode analyses in the full configurational space of the crystal i.e., including the intramolecular and intermolecular degrees of freedom. One- and multiphonon incoherent inelastic neutron scattering intensities are calculated from harmonic analyses in the first Brillouin zone and compared with the experimental data presented here. Phonon dispersion relations and mean-square atomic displacements are derived from the harmonic model and compared with data derived from coherent inelastic neutron scattering and neutron and x-ray diffraction. To examine the temperature effects on the vibrations the full, anharmonic potential function is used in molecular dynamics simulations of the crystal at 80, 140, and 300 K. Several, but not all, of the spectral features calculated from the molecular dynamics simulations exhibit temperature-dependent behavior in agreement with experiment. The significance of the results for the interpretation of the optical spectroscopic results and possible improvements to the model are discussed. © 1995 American Institute of Physics.

    Projections of demand and capacity for colonoscopy related to increasing rates of colorectal cancer screening in the United States (2004)

    Notes: Background : There is debate about the optimal colorectal cancer screening test, partly because of concerns about colonoscopy demand.Aim : To quantify the demand for colonoscopy with different screening tests, and to estimate the ability of the United States health care system to meet demand.Methods : We used a previously published Markov model and the United States census data to estimate colonoscopy demand. We then used an endoscopic database to compare current rates of screening-related colonoscopy with those projected by the model, and to estimate the number of endoscopists needed to meet colonoscopy demand.Results : Annual demand for colonoscopy ranges from 2.21 to 7.96 million. Based on current practice patterns, demand exceeds current supply regardless of screening strategy. We estimate that an increase of at least 1360 gastroenterologists would be necessary to meet demand for colonoscopic screening undergone once at age 65, while colonoscopy every 10 years could require 32 700 more gastroenterologists. A system using dedicated endoscopists could meet demand with fewer endoscopists.Conclusions : Colorectal cancer screening leads to demand for colonoscopy that outstrips supply. Systems to train dedicated screening endoscopists may be necessary in order to provide population-wide screening. The costs and feasibility of establishing this infrastructure should be studied further.

    Anaesthesia in first degree atrioventricular block (1982)

    Notes: A patient with an intracardiac conduction defect characterised by first degree atrioventricular block due to slowed transmission through the atrioventricular node with increased refractoriness of the node, is described. Asymptomatic first degree block, rarely progressing to transient Wenckebach (type 1 second degree) block had been present for a period of 32 years until general anaesthesia was required, when profound bradycardia attributable to complete atrioventricular block developed abruptly. Subsequent investigations located delayed intracardiac conduction through the atrioventricular node, and indicated excess vagal activity rather than structural disease as the cause.The significance of first degree heart block is discussed in relation to other forms of atrioventricular conduction defect and the current recommendations for temporary pacing for elective general anaesthesia.

    Failure to induce over-compensation of growth in maturing yellow perch (2001)

    Notes: Unlike juvenile F1 male bluegill Lepomis macrochrus× female green sunfish L. cyanellus, maximized episodes of compensatory growth (CG) in 2 year yellow perch Perca flavescens did not surpass control masses because internal regulation caused abrupt appetite reduction upon catch-up. Together, the hybrid sunfish study and present work indicate that CG-maximizing feeding schedules and absence of an internal growth limiting mechanism are both required to produce substantial growth overcompensation (GOC). The less vigorous and less resilient CG responses of the yellow perch relative to those of the similarly fed hybrid sunfish appear indicative of the lack of GOC capacity in the former. This contrast, and results of previous studies are interpreted to suggest that GOC capacity may be limited to early life stages of fishes which have a substantial reproductive potential but are at high risk of mortality due to their small size. The possibility that GOC capacity is time-of-year-dependent and species-specific is considered also. Food deprivation periods that produced the strongest CG responses differed for male (2 days) and female (12 days) yellow perch. Among controls fed without restriction, growth rate and growth efficiency of female yellow perch exceeded those of males two-fold, however, males showed a greater capacity to catch-up to same-sex controls when undergoing CG. A feeding schedule using maintenance feeding v. food deprivation to elicit CG yielded the most rapid catch-up to control masses in the yellow perch. Such feeding schedules may produce even greater GOC than was achieved previously in hybrid sunfish, where feeding schedules involving food deprivation were employed.

    Integration Logics: A Review, Extension, and Critique (1970)

    Notes: Compelling as mathematical representations may seem to some interested in the “automaticity” of integration processes, to other empirical theorists they seem anything but obviously relevant. Yet there is a clear trend toward greater use of formal reasoning in both measurement and modeling work on integration processes. Juxtaposing a variety of such integration logics—the mathematical formulae and conceptual abstractions incorporated in assessments of integration progress and regress—should help achieve the major purpose of this article: to introduce students to a variety of possible integration logics, some of their possible interrelationships, and the limitations of some of the simpler ones vis-à-vis current verbal theories of the integration process.
