Using an effective field theory framework we reconsider the problem of radiative corrections from compact dimensions to the 4D gauge couplings. We evaluate the general structure of one-loop contribution from Kaluza-Klein states to the 4D gauge couplings, in models with one-and two-dimensional orbifold compactifications. The calculation includes the additional effect of a non-vanishing constant ...

INTRODUCTION Incidental findings during ultrasound examinations occur frequently with live models in training sessions. Because of the broad scope of training sessions available, the ethics and guidelines of dealing with incidental findings in live models need to be discussed. METHODS We provide a case of an endovaginal ultrasound that had significant unexpected findings. RESULTS This repor...

We have investigated the Mott transition in a quasi-two-dimensional Mott insulator EtMe{3}P[Pd(dmit){2}]{2} with a spin-frustrated triangular-lattice in hydrostatic pressure and magnetic-field [Et and Me denote C2H5 and CH3, respectively, and Pd(dmit){2} (dmit=1,3-dithiole-2-thione-4,5-dithiolate,dithiolate) is an electron-acceptor molecule]. In the pressure-temperature (P-T) phase diagram, a v...
