It is perhaps more surprising that any method of estimating the time of infection by a single time point will result in the estimation of a biased distribution of incubation time. The exact resulting perturbation of the distribution is difficult to predict but plainly, for example, the variance will be overestimated, as the times subject to analysis will have one variance component in themselve...
Civil society has responded to the predicament of marginalised producers by the rapid emergence of the FT market both within the UK and internationally (Barratt Brown, 1993; Crane and Matten, 2004; Lowe and Davenport 2005a). The Fairtrade Mark is now recognised by 52% of the population (Fairtrade Foundation 2006) and there are now over 2,500 retail and catering products carrying the Fairtrade M...
We present a new quantitative technique that determines the times and durations of substorm expansion and recovery phases and possible growth phases based on percentiles of the rate of change of auroral electrojet indices. By being able to prescribe different percentile values, we can determine the onset and duration of substorm phases for smaller or larger variations of the auroral index or in...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
Although many people have expressed alarm that we are witnessing a mass extinction, few projections have been quantified, owing to limited availability of time-series data on threatened organisms, especially plants. To quantify the risk of extinction, we need to monitor changes in population size over time for as many species as possible. Here, we present the world's first quantitative projecti...
Two experiments examined perspective switching in comprehension and retrieval of spatial information. Participants read route or survey descriptions of environments line by line. Reading times were recorded. For half of the descriptions, the perspective of the last sentence was switched. True/false verification of sentences from both perspectives followed the descriptions. Switching perspective...
Two experiments were conducted with beef steers (Exp. 1, average BW of 580 kg; Exp. 2, average BW of 247 kg) to evaluate the use of no supplements (CON) or daily supplementation with (OM basis) .34% of BW of cracked corn (CORN), .34% of BW of wheat bran (WBBW), or .48% of BW of wheat bran (WBISO; calculated to be isocaloric to CORN) on digestive responses (Exp. 1) and live weight gain (Exp. 2)....
Ten Holstein steers (141 kg) were used in two 5 X 5 Latin-square experiments conducted simultaneously to determine the effects of offering different levels and types of feeds with endo: phyte-infected rescue given ad libitum. In Exp. 1, steers wer e given ad libitum access to infected fescue hay in the afternoon; in the morning fescue was given ad lihitum (basal) or bermudagrass or clover hays ...
In contrast to the numerous papers on the influence of changes in the pepsin concentration, the influence of varying the protein concentration on the rate of digestion of protein has been but little studied. Weis ~ found that the rate was nearly directly proportional to the protein concentration in low concentration but increased more slowly than the latter in concentrations of more than 2 to 3...
We study a parsimonious but non-trivial model of the latent limit order book where orders get placed with a fixed displacement from a center price process, i.e., some process between best bid and best ask, and get executed whenever this center price reaches their level. This mechanism corresponds to the fundamental solution of the stochastic heat equation with multiplicative noise for the relat...
