Diboson Production at the Tevatron
We present the latest results on the production of WW, WZ, Wgamma, Zgamma and
ZZ events at the Fermilab Tevatron Collider. The results are based on the
analyses of 0.2 -- 2 /fb of data collected in p pbar collisions at sqrt(s) =
1.96 TeV by CDF and DO experiments during the Tevatron Run II. Analyses of the
diboson production processes provide crucial test of the Standard Model,
directly probing its predictions on the Trilinear Gauge Couplings.Comment: Invited talk at the Hadron Collider Physics Symposium (HCP2008),

MSSM SUSY Searches at LEP2
The status of SUSY searches at LEP2 up to centre-of-mass energy of 202 GeV is
presented. Search strategies for sleptons, squarks, charginos and neutralinos
are discussed in the framework of Minimal Supersymmetric Standard Model with
R-parity conservation. With no indication for the production of these particles
new limits are set on their masses.Comment: Talk presented at 35th Rencontres de Moriond: ElectroWeak

An assessment of the surface turbulent heat fluxes from the NCEP reanalysis over western boundary currents
With the completion of the NCEP-NCAR and ECMWF reanalyses there are now global representations of air-sea surface heat fluxes with sufficient spatial and temporal resolution to be useful in characterizing the air-sea interaction associated with individual weather systems, as well as in developing global-scale oceanic heat and moisture budgets. However, these fluxes are strongly dependent on the numerical models used, and, as a result, there is a clear need to validate them against observations. Accurate air-sea heat flux estimates require a realistic representation of the atmospheric boundary layer, and the implementation of an appropriate surface flux parameterization. Previous work at high latitudes has highlighted the shortcomings of the surface turbulent heat flux parameterization used in the NCEP-NCAR reanalysis during high wind speed conditions, especially when combined with large air-sea temperature differences. Here the authors extend this result through an examination of the air-sea heat fluxes over the western boundary currents of the North Atlantic and North Pacific Oceans. These are also regions where large transfers of heat and moisture from the ocean to the atmosphere take place. A comparison with in situ data shows that the surface layer meteorological fields are reasonably well represented in the NCEP-NCAR reanalysis, but the turbulent heat flux fields contain significant systematic errors. It is argued that these errors are associated with shortcomings in the bulk flux algorithm employed in the reanalysis. Using the NCEP-NCAR reanalysis surface layer meteorological fields and a more appropriate bulk flux algorithm, "adjusted'' fields for the sensible and latent heat fluxes are presented that more accurately represent the air-sea exchange of heat and moisture over the western boundary currents
Individualized immunosuppression in transplant patients: potential role of pharmacogenetics.
The immunosuppressive drugs used to prevent the rejection of transplanted organs have a narrow therapeutic index. Under treatment results in episodes of rejection leading to either damage or loss of the organ. Over immunosuppression increases the risk of infection and malignancy as well as drug specific complications including diabetes mellitus and nephrotoxicity. There is wide variation in the drug dose required to achieve target blood concentrations and there is often dissociation between pharmacokinetics and pharmacodynamics. Currently, immunosuppressive drug treatment is individualized based on a clinical assessment of the risk of rejection or toxicity. Therapeutic drug monitoring is routinely employed for several immunosuppressive drugs. Pharmacogenetics has the potential to complement therapeutic drug monitoring but clinical benefit has yet to be demonstrated. Novel biomarker-based approaches to risk stratification and pharmacodynamic monitoring are under development and are ready for clinical trials
