Title: Looking for a bulk point

Abstract

Here, we consider Lorentzian correlators of local operators. In perturbation theory, singularities occur when we can draw a position-space Landau diagram with null lines. In theories with gravity duals, we can also draw Landau diagrams in the bulk. We also argue that certain singularities can arise only from bulk diagrams, not from boundary diagrams. As has been previously observed, these singularities are a clear diagnostic of bulk locality. We analyze some properties of these perturbative singularities and discuss their relation to the OPE and the dimensions of double-trace operators. In the exact nonperturbative theory, we expect no singularity at these locations. Finally, we prove this statement in 1+1 dimensions by CFT methods.

  • We report on the heat capacity investigation of Cu{sub 55}Hf{sub 45−x}Ti{sub x} metallic glasses. The most appropriate procedure to estimate low temperature electronic and phonon contributions has been determined. Both contributions exhibit monotonous Ti concentration dependence, demonstrating that there is no relation of either the electron density of states at the Fermi level or the Debye temperature to the increased glass forming ability in the Ti concentration range x = 15–30. The thermodynamic parameters (e.g., reduced glass temperature) remain better indicators in assessing the best composition for bulk metallic glass formation.
  • Filling a need of oil specialists to see subsurface formations accurately is a new, three-dimensional (3-D) image-maker. Using computers, geophysicists manipulate seismic data to create accurate pictures of the depth and breadth of subsurface structures. Aboveground-generated sound waves extended thousands of feet into earth layers are picked up by energy-sensing cables, amplified, and recorded on magnetic tape. Seismic impulses reflected from below-surface strata are converted into 3-D images and computerized, allowing new viewing perspectives. Future drillings will confirm the new technique's reliability. 7 figures.
  • The physics of the spin structure of the proton is reviewed. The EMC experiment and the follow-up ones have shown that the quark spin carries about 1/4 of the spin of the proton. The suspected large gluon polarization is under intense studies with various experimental tools. Generalized parton distributions probed in deeply-virtual Compton scattering allows reconstruction of quark orbital angular momentum.
  • The spin structure of the proton has been one of the most important quests driving high-energy spin physics in recent years. In this talk, I review the status of theoretical studies in this area. I will also point out the future opportunities in understanding the proton spin.
  • This paper is part of an ongoing activity of the IEEE Application of Probability Methods Subcommittee to advance the probabilistic methods used to analyze Bulk Power System (BPS) reliability. The objective of the Task Force is to develop a set of guidelines for measuring delivery point reliability. This involves reviewing published literature and other documentation of existing procedures, definitions, and indices. This report presents the results of the Task Force efforts to compile a useful set of terms and procedures for consistent reporting of BPS delivery point reliability.
