background: obesity and diabetes are the most important problems of public health. evidence from molecular animal research and epidemiologic investigations indicate that calcium intake may have an influence on body composition, weight and insulin resistance. the objective of this study was to determine the effects of calcium supplementation on body composition, weight, insulin resistance and bl...

The bright star δ Sco has been considered a typical B0-type object for many years. Spectra of the star published prior to 1990 showed no evidence of emission, but only of short-term line profile variations attributed to nonradial pulsations. Speckle interferometric observations show that δ Sco is a binary system with a highlyeccentric orbit and a period of ∼ 10.6 years. Weak emission in the Hα ...

Reduction of leakage loss by reducing the height of the cylinder is an effective method to improve efficiency in a rotary compressor. There are, however, few challenges we must face by doing so. Below are some problems for reducing the height of the cylinder. 1) In order to keep the same stroke volume, the diameter of the rolling piston needs to be reduced. This change will create a space betwe...

BACKGROUND PET using 18fluorodesoxyglucose (FDG) may offer the possibility of differentiating vital from necrotic residual masses. PATIENTS AND METHODS Seventeen patients with HD and 17 patients with NHL underwent FDG-PET following therapy. According to staging by routine methods at diagnosis, 7 patients presented stage I, 13 stage II, 5 stage III, and 9 stage IV. A dose of 250-400 MBq FDG wa...

We investigate the question of whether ambipolar diffusion (ion-neutral drift) determines the smallest length and mass scale on which structure forms in a turbulent molecular cloud. We simulate magnetized turbulence in a mostly neutral, uniformly driven, turbulent medium, using a three-dimensional, two-fluid, magnetohydrodynamics (MHD) code modified from Zeus-MP. We find that substantial struct...

Identifying peptides from the fragmentation spectra is a fundamental step in mass spectrometry (MS) data processing. The significance (discriminability) of every peak varies, providing additional information for potentially enhancing the identification sensitivity and the correct match rate. However this important information was not considered in previous algorithms. Here we presented a novel ...

Digital Mammograms are currently the most effective imaging modality for early detection of breast cancer but the number of false negatives and false positives is high. Mass is one type of breast lesion and the detection of masses is highly challenged problem. Almost all methods that have been proposed so far suffer from high number of false positives and false negatives. In this paper, a metho...

We provide simple methods for computing exact bounds on expected return and first passage times in finite-state birth-death chains, when the transition probabilities are imprecise, in the sense that they are only known to belong to convex closed sets of probability mass functions. We describe a precise birth-death chain and then we define an imprecise version of it. We present the main results ...
