Geometr ic invariants are shape desrriptors that remain unchanged under geometric transformations such as projection, or change of the viewpoint. In [,?I we devc’loped a new method of obtaining local projert ive antl affine invariants for a general curve without any correspondences. Being local, the invariants are much Ii ss sensitive to occlusion than global invariants . The iniiariants comput...

Preliminary results from the BABAR experiment on charmless B decays to charged pions or kaons, and the measurement of the B→J/ψ K * decay amplitudes are presented. The data sample , collected at the asymmetric-energy B-factory PEP-II at SLAC, comprises a total number of 22.7 million Υ (4S) decays, corresponding to an integrated on-resonance luminosity of approximately 21 fb −1. We measure the f...

Previous studies have employed various models for exploring menu use, focusing mainly on short menus. In this study, long pull-down menus were examined in an item selection experiment. Our base model assumed that 1) the first eye fixation was located at the top, middle, or end of a menu depending on the search item; 2) menu scanning is either downward or upward; 3) the mouse was slowly moved do...

The Wnt signaling pathway plays a conserved role during animal development in transcriptional regulation of distinct targets in different developmental contexts but it remains unclear whether quantitative differences in the nuclear localization of effector proteins TCF and β-catenin contribute to context-specific regulation. We investigated this question in Caenorhabditis elegans embryos by qua...

Abstract. The recent experimental data obtained by the OBELIX group on total p̄p annihilation cross section are analysed; the low energy spin averaged parameters of the p̄p scattering amplitude (the imaginary parts of the S-wave scattering length and P-wave scattering volume) are extracted from the data. Their values are found to be equal to Imasc = −0.69±0.01(stat)±0.03(sys) fm, ImAsc = −0.76±0....

The ν̄e− e− elastic scattering cross-section was measured with a CsI(Tl) scintillating crystal detector array with a total mass of 187 kg at the Kuo-Sheng Nuclear Power Station. The detectors were exposed to a reactor ν̄e flux of 6.4×1012 cm−2s−1 originated from a core with 2.9 GW thermal power. The physics motivations, conceptual design, detector hardware, data analysis and background understand...

In this paper, off-the-shelf algorithms f o r force/torque control are used in the context of mobile manipulation (i.e. coordinated mot ion of a mobile robot base and the a r m mounted o n top of it). In particular, the task of opening a door is studied. To make the solution robust, as f e w assumptions as possible are made. B y using relaxation of forces as the basic level of control, more com...
