We summarize the current top-quark mass measurements from the CDF and DØ experiments at Fermilab. We combine published Run I (1992–1996) results with the most precise published and preliminary Run II (2001–2011) measurements based on data corresponding to up to 9.7 fb−1 of pp̄ collisions. Taking correlations of uncertainties into account, and combining the statistical and systematic uncertaintie...

The flavonoid pigment pathway in plants has been used as a model system for studying gene regulatory mechanisms. C2-Idf is a stable dominant mutation of the chalcone synthase gene, c2, which encodes the first dedicated enzyme in this biosynthetic pathway of maize. Homozygous C2-Idf plants show no pigmentation. This allele also inhibits expression of functional C2 alleles in heterozygotes, produ...

For the first time we search for $\eta_{c2}(1D)$ in $e^+e^-\to\gamma\eta_{c2}(1D)$ at $\sqrt{s}$ = 10.52, 10.58, and 10.867 GeV with data samples of 89.5 fb$^{-1}$, 711 121.4 respectively, accumulated Belle detector KEKB asymmetric energy electron-positron collider. No significant signal is observed mass range between 3.8 3.88 GeV/$c^2$. The upper limit 90\% confidence level on product Born cro...

Information age organizations must effectively utilize new communications capabilities to gain an advantage over their competition. Command and Control (C2) research has demonstrated the potential for decentralization of C2 to improve mission performance in networked battlefields. However, it is unlikely that all future missions will be best executed with a decentralized C2 architecture. Theref...

OBJECTIVE The optimal treatment modality for traumatic spondylolisthesis of the axis is still a controversial issue. Many conservative, posterior and anterior fixation techniques have been used to treat these injuries. The C2 pars (isthmus) was used as a novel screw anchor point in upper cervical spine injuries. The direct C2 pars screws are also used to fixate the posterior and anterior parts ...

LetX be an algebraicK3 surface. Fix an ample divisorH onX ,L ∈ Pic(X) and c2 ∈ Z. Let MH(r;L, c2) be the moduli space of rank r, H-stable vector bundles E over X with det(E) = L and c2(E) = c2. The goal of this paper is to determine invariants (r; c1, c2) for which MH(r;L, c2) is birational to some Hilbert scheme Hilb(X).
