The properties of the amplitude method for Bs oscillation analyses are studied in detail. The world combination of measured amplitudes is converted into a likelihood profile as a function of oscillation frequency. A procedure is proposed to estimate the probability that the minimum observed is due to a statistical fluctuation. This method, applied to the data available at the time of 1999 Winte...
Pseudomonas testosteroni H-8 oxidizes certain lower alkylbenzene sulfonates at rates inversely related to the length of the alkyl group. Appreciable Q(O)2 values were observed for benzene sulfonate (BS), toluene sulfonate (TS), and ethylbenzene sulfonate (EBS), but not for propylbenzene sulfonate (PS) and higher homologues. Catechol oxidation was catalyzed by a constitutive catechol-2,3-oxygena...
The authors argue that complementary hostile and benevolent components of sexism exist across cultures. Male dominance creates hostile sexism (HS), but men's dependence on women fosters benevolent sexism (BS)--subjectively positive attitudes that put women on a pedestal but reinforce their subordination. Research with 15,000 men and women in 19 nations showed that (a) HS and BS are coherent con...
For a finite poset P = (V,≤), let Bs(P ) consist of all triples (x, y, z) ∈ V 3 such that either x < y < z or z < y < x. Similarly, for every finite, simple, and undirected graph G = (V,E), let Bs(G) consist of all triples (x, y, z) ∈ V 3 such that y is an internal vertex on an induced path in G between x and z. The ternary relations Bs(P ) and Bs(G) are well-known examples of so-called strict ...
Nan-Chai-Hu, the root of Bupleurum scorzonerifolium, is a traditional Chinese herb used in treatment of liver diseases such as hepatitis and cirrhosis. We recently reported that the acetone extract of B. scorzonerifolium (BS-AE) could inhibit proliferation and induce apoptosis in A549 human lung cancer cells. We further examined its anti-proliferative mechanisms and in vivo anticancer effect. O...
Bs − Bs mixing is highly important in testing the Standard Model (SM) and constrains strongly its extensions by bounding the unitarity triangle. Since it is a flavor changing neutral process it occurs through loops so that the corresponding mixing amplitude is a sensitive measure of |Vts| and |Vtb|, as the major SM loop contribution comes from t-quark. The mixing of weak interaction eigenstates...

Hepatocellular carcinoma (HCC) accounts for most of primary liver cancer, of which five-year survival rate remains low and chemoprevention has become a strategy to reduce disease burden of HCC. We aim to explore the in vivo chemopreventive effect of an organoselenium-containing compound butaselen (BS) against hepatocarcinogenesis and its underlying mechanisms. Pre- and sustained BS treatment (9...
Although the diagnosis of Gitelman syndrome (GS) and Bartter syndrome (BS) is now feasible by genetic analysis, implementation of genetic testing for these disorders is still hampered by several difficulties, including large gene dimensions, lack of hot-spot mutations, heavy workup time, and costs. This study evaluated in a cohort of patients with genetically proven GS or BS diagnostic sensibil...
In this talk we present a calculation of the dacay rate difference in the neutral Bs − Bs system, ∆ΓBs , in next-to-leading order (NLO) QCD. We find a sizeable decrease compared to leading-order (LO) estimates: (∆Γ/Γ)Bs = (fBs/210MeV ) [0.006B(mb)+0.150BS(mb)−0.0063] in terms of the bag parameters B and BS in the NDR scheme. We put special emphasize on the theoretical and physical implications ...
