Controlled step-by-step dissociation of single iodobenzene molecules has been performed at Cu(111) step-edges using tunneling electrons from a scanning tunneling microscope (STM) tip at 12 K. We show that the threshold tunneling electron energies to break a single bond inside a polyatomic molecule can be determined by using I-V spectroscopy of single molecules. Electron energies of 1.5±0.1 eV a...
Total Variability Model Conventionally formulated as generative model over features Assumes that feature vector distribution is a GMM Distribution Free Formulation Follows from asymptotic normality of Baum-Welch statistics Connections to probabilistic PCA, matrix completion Leads to a stochastic subgradient descent based estimation algorithm Conventional Formulation Collection of feature vector...
Using a high statistics sample of photoproduced charmed particles from the FOCUS experiment at Fermilab (FNAL-E831), we measure the mass splittings of the charmed baryons Σc and Σ ++ c . We find M(Σ 0 c − Λ + c ) = 167.38 ± 0.21 ± 0.13 MeV/c 2 and M(Σ c −Λ + c ) = 167.35±0.19±0.12 MeV/c 2 with samples of 362±36 and 461±39 events, respectively. We measure the isospin mass splitting M(Σ c − Σ 0 c...
We construct a driven sandpile slope model and study it by numerical simulations in one dimension. The model is specified by a threshold slope σc, a parameter α, governing the local current-slope relation (beyond threshold), and jin, the mean input current of sand. A nonequilibrium phase diagram is obtained in the α − jin plane. We find an infinity of phases, characterized by different mean slo...
The stress-induced yielding scenario of colloidal gels is investigated under rough boundary conditions by means of rheometry coupled with local velocity measurements. Under an applied shear stress σ, the fluidization of gels made of attractive carbon black particles dispersed in a mineral oil is shown to involve a previously unreported shear rate response γ dot above(t) characterized by two wel...
The Σc − Σc and Σ∗b − Σb hyperfine mass splittings are computed in the Skyrme model. The hyperfine splittings are suppressed by both 1/Nc and by 1/mQ, where Nc is the number of colors and mQ is the mass of the heavy quark. The Σc, Σ ∗ c , Σb, Σ ∗ b , and Λb masses are predicted in terms of the known values of the Λc, D, D , B and B masses. UCSD/PTH 92-26 hep-ph/9208238 August 1992 1 Baryons con...
We present a new determination of the local temperature function of X-ray clusters using a sample of X-ray clusters with fluxes above 2.2 10−11erg/s/cm2 in the [0.1 − 2.4] keV band, most of these clusters come from the Abell XBAC’s sample to which a handful of known non-Abell clusters has been added. We estimate this sample to be 85% complete, and should therefore provide a useful estimation of...
We present a mean field treatment of a strongly correlated model of electrons in a three–dimensional anisotropic system. The mass of the bare electrons is larger in one spatial direction (the c–axis direction), than in the other two (the ab–planes). We use a slave fermion decomposition of the electronic degrees of freedom and show that there is a transition from a deconfined to a confined phase...
