The familial aggregation of coronary heart disease can be in large part accounted for by a clustering cardiovascular risk factors. To elucidate the determinants disease, many epidemiological studies have focused on behavioral and lifestyle these factors, whereas others examined whether specific candidate genes influence quantitative variation phenotypes.Among Mexican Americans from San Antonio (Tex), we quantified relative contributions both genetic environmental influences to panel...
Higgs boson production via weak fusion at the CERN Large Hadron Collider has capability to determine dominant CP nature of a boson, tensor structure its coupling bosons. This information is contained in azimuthal angle distribution two outgoing forward tagging jets. The technique independent both mass and observed decay channel.
We show how LHC Higgs boson production and decay data can be used to extract gauge fermion couplings of bosons. that very mild theoretical assumptions, which are valid in general multi-Higgs doublet models, sufficient allow the extraction absolute values for rather than just ratios couplings. For masses below 200 GeV we find accuracies $10\ensuremath{-}40%$ total width after several years running. Slightly stronger assumptions on even lead a determination fermions at level...
Chemerin is a novel adipokine previously associated with metabolic syndrome phenotypes in small sample of subjects from Mauritius.The aim the study was to determine whether plasma chemerin levels were larger second, unrelated human population.Plasma samples obtained San Antonio Family Heart Study (SAFHS), large family-based genetic epidemiological including 1431 Mexican-American individuals. Individuals randomly sampled without regard phenotype or disease status. This well-characterized for...
We investigate Higgs boson pair production at hadron colliders for masses ${m}_{H}<~140\mathrm{GeV}$ and the rare decay of one two bosons.

A luminosity-upgraded LHC could improve this considerably. 200...
Weak boson fusion is a copious source of intermediate mass Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze $\stackrel{\ensuremath{\rightarrow}}{H}\ensuremath{\tau}\ensuremath{\tau}$ decay mode standard model boson.

We report the experimental verification of metamaterial cloaking for a 3D object in free space. apply plasmonic technique, based on scattering cancellation, to suppress microwave from finite-length dielectric cylinder. verify that suppression is obtained all around near- and far-field different incidence angles, validating our measurements with analytical results full-wave simulations. Our near-field confirm realistic robust cloaks may be realized elongated objects moderate transverse...
We present cross sections and differential distributions for QCD radiative corrections to the processes $p\stackrel{\ensuremath{\rightarrow}}{p}W+2$ jets $p\stackrel{\ensuremath{\rightarrow}}{p}Z+2$ at CERN Large Hadron Collider (LHC). Calculations are performed with Monte Carlo program MCFM. Cross section dependence on renormalization factorization scales is greatly reduced, except heavy-flavor case of ${W}^{\ifmmode\pm\else\textpm\fi{}}b\overline{b},$ which has new features next-to-leading...

Inclusive standard model Higgs boson pair production and subsequent decay to same-sign dileptons via weak gauge W+/- bosons at the CERN Large Hadron Collider (LHC) has capability determine self-coupling, lambda. The large top quark mass limit is found not be a good approximation for signal if one wishes utilize differential distributions in analysis. We find that it should possible LHC with design luminosity establish nonzero self-coupling lambda/lambda(SM) can restricted range of 0-3.7 95%...
The purely electroweak process $\mathrm{qq}\ensuremath{\rightarrow}\mathrm{qqZ}$ (via $t$-channel $\frac{\ensuremath{\gamma}}{Z}$ or $W$ exchange) provides a copious and fairly clean source of color-singlet exchange events in $\mathrm{pp}$ collisions at the CERN LHC. A judicious choice phase-space region allows suppression QCD backgrounds to level signal. color-singlet-exchange signal can be distinguished from by radiation patterns additional minijets individual events. rapidity-gap trigger...
We consider QCD $t\overline{t}\ensuremath{\gamma}$ and $t\overline{t}Z$ production at hadron colliders as a tool to measure the $tt\ensuremath{\gamma}$ $ttZ$ couplings. At Tevatron it may be possible perform first, albeit not very precise, test of vector axial couplings in production, provided that more than $5\text{ }\text{ }{\mathrm{f}\mathrm{b}}^{\ensuremath{-}1}$ integrated luminosity are accumulated. The cross section is too small observable. CERN Large Hadron Collider (LHC) will probe...
Top quark pair production at proton-antiproton colliders is known to exhibit a forward-backward asymmetry due higher-order QCD effects. We explore how this might be studied the Fermilab Tevatron, including depends on kinematics of extra hard partons. consider results for top events with one and two additional jets. further note that similar asymmetry, correlated presence jets, arises in specific models parton showers Monte Carlo simulations. conclude measurement Tevatron will challenging,...
The narrow-width approximation is used in high-energy physics to reduce the complexity of scattering calculations. It a fortunate accident that it works so well for standard model, but general will fail context new physics. We find numerous examples significant corrections when calculation performed fully off shell including finite width, notably from effects decay matrix elements, not just phase space. If taken into account, attempts reconstruct Lagrangian discovery data would result...

Abstract High plasma levels of lipoprotein(a) (Lp(a)) and its unique apolipoprotein, apo(a), are an independent risk factor for cardiovascular disease. Plasma Lp(a) vary over a 1000-fold range determined by the apo(a) locus, which has at least 34 alleles expressing isoforms with molecular weights from 800,000. In addition, null produce no detectable apo(a). We used primary cultures baboon hepatocytes to investigate basis phenotypes. Immunoprecipitation after radiolabeling revealed that some...
