They say essential reverse baleful influence Chicago School antitrust, which, telling, disastrously and abruptly ended 1980s a “golden” era beneficially lively antitrust enforcement. In fact, enforcement was, best, uneven, ...

Every cell’s genome contains two main classes of functional DNA. The best understood type of DNA sequence, which was also the first to be discovered, is that which encodes RNA and protein products via the near-universal “genetic code” (1). A more mysterious but equally important class of functional DNA is cisregulatory sequence, which does not have a physical product but, instead, encodes the c...

This paper analyzes a single television station’s choice of airing tune-ins (preview advertisements). I consider two consecutive programs located along a unit line. Potential viewers know the earlier program but are uncertain about the later one. They may learn its location through a tune-in if they watch the earlier program and the television station chose to air a tune-in, or by sampling it f...

In order to study the wakefield effects of an electron cloud, a test bunch was placed behind a bunch train, where the cloud density rapidly varied. A currentdependent tune shift and the tune spread of the test bunch were measured as a function of the bunch current while varying the bucket position of the test bunch. The vertical tune shift indicated a strong defocusing force together with a wid...
