Radar is a key sensing technology for advanced driver assistance systems and autonomous vehicles due to its strong detection capability, long range, robustness environmental variations such as inclement weather lighting extremes. As these radars demonstrate increased levels of integration performance [1,3], it desired have single multimode radar transceiver that can address the stringent form factor constraints corner wide narrow field-of-view requirements front used in urban highway...
The Collins effect connects transverse quark spin with a measurable azimuthal asymmetry in the yield of hadronic fragments around quark's momentum vector. Using two different reconstruction methods we measure statistically significant asymmetries for charged pion pairs ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at center-of-mass energies 10.52 GeV and 10.58 GeV, which can be attributed to fragmentation primordial quarks components. measurement was performed using data set $547\text{ }\text{...
We report the results of a search for charmonium-like state produced in process gamma --> omega J/psi 3.9-4.2 GeV/c^2 mass region. observe significant enhancement, which is well-described by resonant shape with M = (3915 +/- 3 2) MeV/c^2 and total width Gamma (17 10 3) MeV. This enhancement may be related to one or more three states so far reported 3.90-3.95
We report a study of $B\to (J/\psi \gamma) K$ and (\psi' \gamma)K$ decay modes using $772\times 10^{6}$ $B\bar{B}$ events collected at the \Upsilon(4S)$ resonance with Belle detector KEKB energy-asymmetric $e^+ e^-$ collider. observe $X(3872) \to J/\psi \gamma$ first evidence for $\chi_{c2} in (X_{c\bar{c}}\gamma) decays, while search \psi' no significant signal is found. measure branching fractions, $\mathcal{B}(B^{\pm} X(3872) K^{\pm}) \mathcal{B}(X(3872) J/\psi\gamma)$ $=$...
Abstract The receptor tyrosine kinase EphB2 is expressed by colon progenitor cells; however, only 39% of colorectal tumors express and expression levels decline with disease progression. Conversely, EphB4 absent in normal but all 102 cancer specimens analyzed, its level correlates higher tumor stage grade. Both are regulated the Wnt pathway, activation which critically required for progression cancer. Differential usage transcriptional coactivator cyclic AMP-responsive element binding...
Using 605 fb−1 of data collected at the Υ(4S) resonance we present a measurement inclusive radiative B-meson decay channel, B→Xsγ. For lower photon energy thresholds 1.7, 1.8, 1.9, and 2.0 GeV, as defined in rest frame B meson, measure partial branching fraction mean variance spectrum. At 1.7 GeV threshold obtain BF(B→Xsγ)=(3.45±0.15±0.40)×10−4, where errors are statistical systematic.Received 8 July 2009DOI:https://doi.org/10.1103/PhysRevLett.103.241801©2009 American Physical Society
Millimeterwave (mm-Wave) radar sensors operating in the 76-to-81 GHz band are a key component of advanced driver-assistance systems (ADAS) for enhanced automotive safety. The recent entry CMOS solutions this space has accelerated development multi-mode Radars that can support long, medium and short-range applications [1-3]. As ADAS evolve to higher levels autonomy, there is increased demand on improved maximum range, velocity, angular resolution. Emerging in-cabin occupancy sensing creating...
Excess Al<sup>3+</sup> ions are considered toxic to living organisms.
Ultrasonic velocities (u), densities (ρ), viscosities (η), relative permittivities (ε), and refractive indicies (nD) of mixtures acetonitrile with dimethylacetamide, dimethyl sulfoxide, nitrobenzene, methanol have been measured at 25 °C. From u, ρ, η, isentropic compressibilities (κs), its deviation from ideal behavior excess (Δη) computed. nD ε, the Kirkwood correlation factor, g, has also evaluated.
EphB4 is a member of the largest family transmembrane receptor tyrosine kinases and plays critical roles in axonal pathfinding blood vessel maturation. We wanted to determine biological role ovarian cancer. studied expression seven normal specimens 85 invasive carcinomas by immunohistochemistry. was largely absent surface epithelium, but expressed 86% cancers. significantly associated with advanced stage disease presence ascites. Overexpression predicted poor survival both univariate...
