We report the first observation of the reactions + ρ 0 with the STAR detector. The ρ are produced at small perpendicular momentum, as expected if they couple coherently to both nuclei. We discuss models of vector meson production and the correlation with nuclear breakup, and present a fundamental test of quantum mechanics that is possible with the system.

A bstract In this work, we discuss the possibility to test Heavy Neutral Leptons (HNLs) using “Cosmic Ray Beam Dump” experiments. analogy with terrestrial beam dump experiments, where a first hits target and is then absorbed by shield, consider high-energy incident cosmic rays impinging on Earth’s atmosphere surface. We focus here HNL production from atmospherically produced kaon, pion D -meson...

This paper documents the exploration significance of Ag/Au, Au/Cu, Cu/Mo and (Ag×Au)/Cu×Mo) ratios of the supra-ore and sub-ore halos versus fluid inclusion evolution for 24 Cu, 6 Cu- Mo and 10 Cu-Au porphyry deposits worldwide. The ratios are based only on the economic and mineralized hypogene alteration zones. The results indicate that (Ag×Au)/(Cu×Mo), Au/Cu and Cu/Mo ratios increase with dec...

The spin-polarized calculations in generalized gradient approximation density–functional theory (GGA–DFT) have been used to show how the existence of second metals can modify the atomic hydrogen adsorption on Au (100), Cu (100), and Pt (100) surfaces. The computed adsorption energies for the atomic hydrogen adsorbed at the surface coverage of 0.125 ML (monolayer) for the monometallic Au (100), ...

Thor is an object-oriented database management system that is designed to be scalable in a distributed environment. Thor allows objects to be stored persistently and accessed efficiently while providing ACID transaction semantics. In this paper, we propose to extend Thor with a snapshot utility. Snapshots are useful for a wide range of applications, including data analysis, data mining and data...

first principle calculations were performed using density functional theory within the local spin density approximation (lsda) to understand the electronic properties of au(100)+tbt system and compare the results with au(100) and bulk au properties. band structure, the total dos and charge density for these materials are calculated. we found that the homo for au(100)+tbt becomes broader than au...

In pursuing the history of any field, even one in which many of the main exponents are still alive, it can be very difficult to establish facts and priorities. Detailed scrutiny of the events leading to the recognition of the antidepressant effects of iproniazid, in which Nathan Kline was involved, may fail to establish the exact sequence of events or the sources of inspiration for a discovery ...
