There is persuasive evidence that the role of the mitotic apparatus (MA) in cytokinesis is to control the location of the cleavage furrow. The geometric aspects of this interaction between the MA and the cortex are complex and, thus, computer simulation can be a useful means for testing hypotheses about the induction process. White and Borisy (1983. J. Theor. Biol. 101:289-316) used computer si...
The exact frame-dragging (or Lense-Thirring (LT) precession) rates for Kerr, Kerr-Taub-NUT (KTN) and Taub-NUT spacetimes have been derived. Remarkably, in the case of the ‘zero angular momentum’ Taub-NUT spacetime, the frame-dragging effect is shown not to vanish, when considered for spinning test gyroscope. In the case of the interior of the pulsars, the exact framedragging rate monotonically ...
purpose: the aim of this paper is to survey the rate of the precision in the audio and visual material retrieval by clustering techniques and k- means algorithm. methodology: the type of the research method is experimental. for the purpose of this paper, twenty- three albums are studied directly through observation. albums published in summer 1391(solar). songs catalogs according to pbcore meta...
Objective(s): The present study was conducted to examine whether the standardized uptake value (SUV) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (PET) images, obtained via two methods based on time-of-flight (TOF) reconstruction and point spread function (PSF). Methods: A cylinder phantom with the sphere (30mm diameter), located in...
We study a variant of the canonical $k$-center problem over set vertices in metric space, where underlying distances are apriori unknown. Instead, we can query an oracle which provides noisy/incomplete estimates distance bet...
OBJECTIVE Infections due to Gram-negative bacteria exhibit seasonal trends, with peak infection rates during warmer months. We hypothesized that the likelihood of a bloodstream infection due to Gram-negative bacteria increases with proximity to the equator. We tested this hypothesis and identified geographical, climatic and social factors associated with this variability. DESIGN We establishe...
