What the Oblique Parameters S, T, and U and Their Extensions Reveal About the 2HDM: A Numerical Analysis

The oblique parameters S, T, and U and their higher-order extensions (V, W, and X) are observables that combine electroweak precision data to quantify deviation from the Standard Model. These parameters were calculated at one loop in the basis-independent CP-violating Two-Higgs Doublet Model (2HDM). The scalar parameter space of the 2HDM was randomly sampled within limits imposed by unitarity and found to produce values of the oblique parameters within experimental bounds, with the exception of T. The experimental limits on T were used to predict information about the mass of the charged Higgs boson and the difference in mass between the charged Higgs boson and the heaviest neutral Higgs boson (m_ch - m_3). In particular, it was found that the 2HDM predicts -600 GeV 250 GeV being preferred. The mass scale of the new physics produced by random sampling was consistently fairly high, with the average of the scalar masses falling between 400 and 800 GeV for Y_2 = m_W^2, although the model can be tuned to produce a light neutral Higgs mass (eg, 120 GeV). Hence, the values produced for V, W, and X fell well within .01 of zero, confirming the robustness of the linear expansion approximation. Taking the CP-conserving limit of the model was found to not significantly affect the values generated for the oblique parameters.Comment: 17 pages, 31 figure

\u3ci\u3eAcrobasis\u3c/i\u3e Shoot Moth (Lepidoptera: Pyralidae) Infestation-Tree Height Link in a Young Black Walnut Plantation

Acrobasis shoot moth infestations were evaluated in a young black walnut progeny test for 4 years, from ages 3 to 6. Infestation levels were greatest on the largest trees in the fourth and fifth year after plantation establishment, and were declining by the sixth year. Acrobasis infestation appears to be a problem primarily on young trees less than 2.5 m in height. There was no evidence for genetic resistance to Acrobasis infestation in black walnut

Molecular Basis of C–N Bond Cleavage by the Glycyl Radical Enzyme Choline Trimethylamine-Lyase

Deamination of choline catalyzed by the glycyl radical enzyme choline trimethylamine-lyase (CutC) has emerged as an important route for the production of trimethylamine, a microbial metabolite associated with both human disease and biological methane production. Here, we have determined five high-resolution X-ray structures of wild-type CutC and mechanistically informative mutants in the presence of choline. Within an unexpectedly polar active site, CutC orients choline through hydrogen bonding with a putative general base, and through close interactions between phenolic and carboxylate oxygen atoms of the protein scaffold and the polarized methyl groups of the trimethylammonium moiety. These structural data, along with biochemical analysis of active site mutants, support a mechanism that involves direct elimination of trimethylamine. This work broadens our understanding of radical-based enzyme catalysis and will aid in the rational design of inhibitors of bacterial trimethylamine production.National Science Foundation (U.S.) (Grant 0645960

in Violence Against Women, (2002)

This substantial article examines the issues of men who are victimized by domestic violence in heterosexual relationships. Over the past several years, there has increasing attention to the issues of men who are victimized by heterosexual domestic violence, most of which is based on research done that is based on the Conflict Tactics Scale (CTS) developed by Murray Straus and Richard Gelles. In this current paper, Kimmel addresses the research that suggests men are victimized as often as women from both substantive and methodological perspectives. Through the process, Kimmel also addresses the CTS and raises substantive issues with the continued use of this tool to examine domestic violence. Kimmel notes that the language (both media and in much of the specialized literature and theory) describing domestic violence has increasingly come to be that of gender symmetry. Review of the research (Fierbert, 1997, Archer, 2000) found that between 79 and 82 empirical and 16 review articles that demonstrated gender symmetry. As Kimmel notes, these studies “raise troubling questions ” about what has come to be accepted as relatively common knowledge about domestic violence – that it is something men do to women, that it is one of the leading causes of serious injury to women, and that it is one of the world’s most widespread public health issues. Beyond this, however, the research suggesting gender symmetry raises far more questions than it supposed answers. These questions largely revolv
