Does investment call the tune? Empirical evidence and endogenous theories of the business cycle

Theories of the business cycle can be classified into two main groups, exogenous and endogenous, according to the way they explain economic fluctuations—either as responses of the economy to factors that are external (exogenous shocks) or as upturns and downturns of the economic system internally generated (by endogenous factors). In endogenous theories investment is generally a key variable to...

Tune Measurement at the Tevatron

The Tevatron is a single beam pipe machine which contains both protons and anti-protons for HEP. This poses a challenge for measuring betatron tunes because of the possibility of contamination from the other species. In order to overcome this problem, stripline type structures are usually used because they are directional by construction or for the case of the 21.4 MHz Schottky system, a clever...

The RHIC Tune Measurement System

Each of the four fractional betatron tunes of RHIC (two planes, two rings) is measured with a transverse beam kicker and dedicated beam position monitor (BPM). A 15kV pulse is generated by a fast FET switch, passed through a stripline kicker, attenuated, and returned to the instrumentation control room (ICR) for monitoring. When pulsed at 3kV, the four-meter long kicker gives a gold beam at inj...

Tune or Text? Tune-text accommodation strategies in Portuguese

In Portuguese, different strategies for dealing with tune-text accommodation have been reported. However, no systematic research has been conducted exploring crucial cases of complex nuclear melodies realized in nuclear words with final stress, as in yes-no questions. Based on reading and semispontaneous data from ten regions in Brazil and eleven regions in Portugal, this study reveals that Bra...
