We provide the first evidence for a holographic correspondence between a gravitational theory in flat space and a specific unitary field theory in one dimension lower. The gravitational theory is a flat-space limit of topologically massive gravity in three dimensions at a Chern-Simons level of k=1. The field theory is a chiral two-dimensional conformal field theory with a central charge of c=24.

We report on the systematic investigation of the role of surface nanoscale roughness and morphology on the charging behaviour of nanostructured titania (TiO2) surfaces in aqueous solutions. IsoElectric Points (IEPs) of surfaces have been characterized by direct measurement of the electrostatic double layer interactions between titania surfaces and the micrometer-sized spherical silica probe of ...

Performance data collected on two sets of 8-cm diameter carbon-carbon (C-C) ion optics assemblies are presented in this paper. Each C-C grid was designed and fabricated to grid feature geometries that were identical to the NSTAR ion engine and their performance was characterized by mounting them to an 8-cm diameter Structurally Integrated Thruster (SIT-8). Electron backstreaming and impingement...

Porous electrodes are widely used in electrochemical systems instead of flat electrodes to boost storage capacities for ions and electrons, to improve the transport of mass and charge, and to enhance reaction rates. Existing porous electrode theories make a number of simplifying assumptions: (i) The charge-transfer rate is assumed to depend only on the local electrostatic potential difference b...

For the Helmholtz equation (with wavenumber k) and analytic curves or surfaces Γ we analyze the mapping properties of the single layer, double layer as well combined potential boundary integral operators. A k-explicit regularity theory for the single layer and double layer potentials is developed, in which these operators are decomposed into three parts: the first part is the single or double l...

In this note, small amplitude free vibration of a double-beam system in presence of inner layer nonlinearity is investigated. The nonlinearity is due to inner layer material and is not related to large amplitude vibration. At first, frequencies of a double-beam system with linear inner layer are studied and categorized as synchronous and asynchronous frequencies. It is revealed that the inner l...
