Cash flows to hedge funds are highly sensitive performance streaks, a streak being defined as subsequent quarters during which fund performs above or below benchmark, even after controlling for wide range of common measures. At the same time, streaks have limited predictive power regarding future performance. This suggests investors weigh information suboptimally, and their decisions driven too...

This article deals with the lemmatization of Middle Dutch literature. This text collection—like any other medieval corpus—is characterized by an enormous spelling variation, which makes it difficult to perform a computational analysis of this kind of data. Lemmatization is therefore an essential preprocessing step in many applications, since it allows the abstraction from superficial textual va...

We report preliminary results of lattice super-Yang-Mills computations using domain wall fermions, performed at an actual rate of 1000 Gflop/s, over the course of six months, using two BlueGene/L racks at Rensselaer’s CCNI supercomputing center. This has allowed us to compute the gluino condensate and string tension over a wide range of lattice parameters, setting the stage for continuum, chira...

To the Editor: In South Africa, a substantial segment of the population is overweight.1 In 2000, non-communicable diseases (NCDs) accounted for 37% of deaths among adults2 and this figure is rising alongside expanding waistlines. Overweight children are twice as likely to have elevated blood pressure, 13 times more likely to have elevated insulin levels, and 7 times more likely to have higher t...
