We consider the cosmology of a " 3-brane universe " in a five dimensional (bulk) space-time with a cosmological constant. We show that Einstein's equations admit a first integral, analogous to the first Friedmann equation, which governs the evolution of the metric in the brane, whatever the time evolution of the metric along the fifth dimension. We thus… (More)

BACKGROUND
Digital image analysis has been introduced into the diagnosis of skin lesions based on dermoscopic pictures.
OBJECTIVES
To develop a computer algorithm for the diagnosis of melanocytic lesions and to compare its diagnostic accuracy with the results of established dermoscopic classification rules.
METHODS
In the Department of Dermatology,… (More)

The Supersymmetry Les Houches Accord (SLHA) [1] provides a universal set of conventions for conveying spectral and decay information for supersymmetry analysis problems in high energy physics. Here, we propose extensions of the conventions of the first SLHA to include various gener-alisations: the minimal supersymmetric standard model with violation of CP,… (More)

The Fortran code NMHDECAY computes the masses, couplings and decay widths of all Higgs bosons of the NMSSM in terms of its parameters at the electroweak (or Susy breaking) scale: the Yukawa couplings λ and κ, the soft trilinear terms A λ and A κ , and tan β and µ eff = λ S. The computation of the spectrum includes leading two loop terms, electroweak… (More)

We describe the the improved properties of the NMHDECAY program, that is designed to compute Higgs and sparticle masses and Higgs decay widths in the NMSSM. In the version 2.0, Higgs decays into squarks and sleptons are included, accompagnied by a calculation of the squark, gluino and slepton spectrum and tests against constraints from LEP and the Tevatron.… (More)

NMSPEC is a Fortran code that computes the sparticle and Higgs masses, as well as Higgs decay widths and couplings in the NMSSM, with soft susy breaking terms specified at M GUT. Exceptions are the soft singlet mass m 2 s and the singlet self coupling κ, that are both determined in terms of the other parameters through the minimization equations of the… (More)

We identify scenarios not ruled out by LEP data in which NMSSM Higgs detection at the LHC will be particularly challenging. We first review the 'no-lose' theorem for Higgs discovery at the LHC that applies if Higgs bosons do not decay to other Higgs bosons — namely, with L = 300 fb −1 , there is always one or more 'standard' Higgs detection channel with at… (More)

We perform a calculation of the full momentum dependence of the gluon and ghost propagators in pure SU(3) Yang–Mills theory by integrating Wil-son's exact renormalization group equations with respect to an infrared cutoff k. The heavy quark potential in the quenched approximation can be expressed in terms of these propagators. Our results strongly indicate… (More)

We discuss the exact renormalization group or flow equation for the effective action and its decomposition into one particle irreducible N point functions. With the help of a truncated flow equation for the four point function we study the bound state problem for scalar fields. A combination of analytic and numerical methods is proposed, which is applied to… (More)

In several phase II-trials encouraging tumour responses rates in advanced metastatic melanoma (stage IV; AJCC-classification) have been reported for the application of biochemotherapy containing interleukin 2. This study was designed to compare the efficacy of therapy with dacarbazine (DTIC) and interferon alpha (IFN-alpha) only to that of therapy with DTIC… (More)
