12 We discuss the use of resonant photoemission in the study of rare earth/transition metal perovskites and perovskite-related structures. We illustrate its application to the assignment of the RE and TM valence band density of states in Nd2Ni1−xCuxO4 and REBaCo2O5+δ. In both cases, the relative positions of the 4f and 3d contributions within the valence band density of states (DOS) relative to...
We report initial results of the Antarctic Impulsive Transient Antenna (ANITA) 2006-2007 Long Duration Balloon flight, which searched for evidence of the flux of cosmogenic neutrinos. ANITA flew for 35 days looking for radio impulses that might be due to the Askaryan effect in neutrino-induced electromagnetic showers within the Antarctic ice sheets. In our initial high-threshold robust analysis...
The tiny general relativistic Lense-Thirring effect can be measured by means of a suitable combination of the orbital residuals of the nodes of LAGEOS and LAGEOS II and the perigee of LAGEOS II. This observable is affected, among other factors, by the Earth’ s solid and ocean tides. They induce long-period orbital perturbations that, over observational periods of few years, may alias the detect...
The thermal Sunyaev-Zel’dovich effect is an important probe of clusters of galaxies, and has the attractive property of being proportional to the thermal energy content of the intracluster medium. With the assistance of X-ray data, the effect can be used to measure the number of hot electrons in clusters, and thus measure cluster baryon contents. Cluster absolute distances and other structural ...
This research is aimed to study whether we will have the same attitude change when we have the same intensity of cognitive or emotional level for attitude. People who have higher involvement will be persuaded by central route and low involvement will be persuaded by peripheral route: the matching effect in attitude change. The present study controlled the intensity of both cognitive and emotion...
We discuss the decay of accelerated protons and illustrate how the FullingDavies-Unruh effect is indeed mandatory to maintain the consistency of standard Quantum Field Theory. The confidence level of the Fulling-Davies-Unruh effect must be the same as that of Quantum Field Theory itself.
With the Doha Round of the WTO stalled indefinitely, bilateral free trade agreements (FTAs) have proliferated. While countries in Asia were relative latecomers to preferential liberalization, they have been catching-up rapidly. Indeed, the proliferation of FTAs has been greatest in Asia over the past decade. As of January 2013, there are 109 FTAs involving an Asian country already in effect, 13...
