A new measure, the accommodating function, for the quality of on-line algorithms is presented. The accommodating function, which is a generalization of both the competitive ratio and the accommodating ratio, measures the quality of an on-line algorithm as a function of the resources that would be suucient for some algorithm to fully grant all requests. More precisely, if we have some amount of ...

The visual abstraction procedure used in previous studies of declination was tested using 12 subjects who each fit the F0 contours of 19 spoken short simple sentences with baselines. These baselines were found to be poorly replicated the fitters. An objective all-points least-squares best-fit procedure was tested on this corpus and on a set of sentences that had been produced in both spontaneou...

We fit the Doppler profiles of the He-like triplet complexes of O VII and N VI in the X-ray spectrum of the O star ζ Pup, using XMM-Newton RGS data collected over ∼ 400 ks of exposure. We find that they cannot be well fit if the resonance and intercombination lines are constrained to have the same profile shape. However, a significantly better fit is achieved with a model incorporating the effe...

Nearly 50 % of newly diagnosed colorectal cancer, affect people over 70 years of age. Inclusion of older patients in clinical trials has been extremely rare. As a result, there is debate on how to manage these patients because it is still unclear how to balance the therapeutic advantages and toxicities. For patients who do not have comorbid conditions, with performance status (P.S.) 0–1, treatm...

of the variation in the data, and we would disagree that the straight line is “obviously bad” or “not a good description of the data.” We do not advocate elimination of the term “test for the significance of the regression,” but we would like to see the term “goodness of fit” associated with F = MSifMS and dissociated from F = MS101/MSpe. The larger the value of F = MSiact / MS, the greater is ...

This paper studies the dynamic bin packing problem, in which items arrive and depart at arbitrary time. We want to pack a sequence of unit fractions items (i.e., items with sizes 1/w for some integer w ≥ 1) into unit-size bins such that the maximum number of bins used over all time is minimized. Tight and almost-tight performance bounds are found for the family of any-fit algorithms, including ...

We describe a class of self-similar processes that can be used to fit self-similar data, and give a fast, efficient on-line algorithm for simulating them.

In this work we develop techniques that can derive the tumor position from external respiratory surrogates (abdominal surface motion) through periodically updated internal/external correlation. A simple linear function is used to express the correlation between the tumor and surrogate motion. The function parameters are established during a patient setup session with the tumor and surrogate pos...

We present a cavity ring-down spectrometer which was developed for near-infrared measurements of laser absorption by atmospheric greenhouse gases. This system has several important attributes that make it possible to conduct broad spectral surveys and to determine line-by-line parameters with wide dynamic range, and high spectral resolution, sensitivity and accuracy. We demonstrate a noise-equi...
