Interactive node-link diagrams are useful for describing and exploring data relationships in many domains such as network analysis and transportation planning. We describe a multi-touch interaction technique set (IT set) that focuses on edge interactions for node-link diagrams. The set includes five techniques (TouchPlucking, TouchPinning, TouchStrumming,(More)
We report on the engineering of a nondispersive (flat) energy band in a geometrically frustrated lattice of micropillar optical cavities. By taking advantage of the non-Hermitian nature of our system, we achieve bosonic condensation of exciton polaritons into the flat band. Because of the infinite effective mass in such a band, the condensate is highly(More)
This paper investigates the accuracy of forecasts from four DSGE models for inflation, output growth and the federal funds rate using a real-time dataset synchronized with the Fed’s Greenbook projections. Conditioning the model forecasts on the Greenbook nowcasts leads to forecasts that are as accurate as the Greenbook projections for output growth and the(More)
BACKGROUND The incidence of hepatocellular carcinoma (HCC) has continued to rise in recent years. This increase has been attributed to alcohol-induced liverdiseases, metabolic syndrome, and the rising number of hepatitis B and C viral infections. METHOD Pertinent publications (2000-2011) were retrieved by a systematic Medline search. In seven different(More)
BACKGROUND AND AIM Hepatocellular carcinoma (HCC) is the third most common reason for cancer-related death worldwide. Many countries either lack appropriate clinical practice guidelines for the diagnosis and treatment of HCC or the quality of their guidelines has never been evaluated. The main objective of our work was to identify published HCC guidelines(More)
Since the establishment of miniaturized extracorporeal circulation (mECC), there has been a great controversy about a possible increased risk of gaseous microembolism as compared to conventional extracorporeal circulation (cECC). From March 2005 to June 2006, a prospective, randomized study, comparing three different mECC (MECC, PRECiSe, Resting Heart) with(More)
We study the coherence and fluorescence properties of the coherently pumped and dissipative Jaynes-Cummings-Hubbard model describing polaritons in a coupled-cavity array. At weak hopping we find strong signatures of photon blockade similar to single-cavity systems. At strong hopping the state of the photons in the array depends on its size. While the photon(More)
Mediated photon-photon interactions are realized in a superconducting coplanar waveguide cavity coupled to a superconducting charge qubit. These nonresonant interactions blockade the transmission of photons through the cavity. This so-called dispersive photon blockade is characterized by measuring the total transmitted power while varying the energy(More)
