BACKGROUND Sentence comprehension requires linguistic processing as well as cognitive resources such as working memory (WM) and information-processing speed (IPS). The authors hypothesize that sentence comprehension difficulty in patients with mild PD is due to degradation of the large-scale neural network that supports cognitive resources during sentence(More)
Extended Abstract The necessity for mechanisms that provide service survivability (i.e., seamless restoration of networking services affected by random failures) in battlefield networks, is both obvious and critical. This paper addresses the fundamental challenge of providing service survivability via efficient fault localization and self-healing techniques(More)
The photon spectrum in the inclusive electromagnetic radiative decays of the B meson, B → X(s)γ plus B → X(d)γ, is studied using a data sample of (382.8 ± 4.2) × 10(6)Υ(4S) → BB decays collected by the BABAR experiment at SLAC. The spectrum is used to extract the branching fraction B(B → X(s)γ) = (3.21 ± 0.33) × 10(-4) for E(γ) >1.8 GeV and the direct CP(More)
Blood samples were collected from 1328 dairy cows of different parities in 46 herds in two regions of South Korea and tested for bovine viral diarrhoea virus (BVDV) by reverse transcriptase-PCR (RT-PCR) for the detection of viral sequences in whole blood and by a commercial elisa for the detection of bvdv-specific antibodies. None of the animals was(More)
Hypertension is associated with neurodegenerative diseases and cognitive impairment. Several studies using spontaneous hypertensive rats to study the effect of hypertension on memory performance and adult hippocampal neurogenesis have reached inconsistent conclusions. The contradictory findings may be related to the genetic variability of spontaneous(More)
Recent astrophysical and terrestrial experiments have motivated the proposal of a dark sector with GeV-scale gauge boson force carriers and new Higgs bosons. We present a search for a dark Higgs boson using 516 fb(-1) of data collected with the BABAR detector. We do not observe a significant signal and we set 90% confidence level upper limits on the product(More)
We report the observation of the decay B- → D(s)((*)+) K- ℓ- ν(ℓ) based on 342  fb(-1) of data collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e+ e- storage rings at SLAC. A simultaneous fit to three D(s)(+) decay chains is performed to extract the signal yield from measurements of the squared missing mass in the B meson decay. We(More)
We present measurements of branching fractions and charge asymmetries for seven B-meson decays with an eta, eta', or omega meson in the final state. The data sample corresponds to 89x10(6) BB pairs produced from e(+)e(-) annihilation at the Upsilon(4S) resonance. We measure the following branching fractions in units of 10(-6): B(B+-->eta(More)
STUDY DESIGN Magnetic resonance images (MRIs) were used to determine the geometry of the tissues studied. OBJECTIVE To investigate the geometric parameters of tissues around the lumbosacral joint. SUMMARY OF BACKGROUND DATA Cross-sectional area (CSA), moment arms, and line of action of the tissues located at lumbosacral joint (L5-S1), which are(More)
