We consider a series of n single-server queues, each with unlimited waiting space and the first-in first-out service discipline. Initially, the system is empty; then k customers are placed in the first queue. The service times of all the customers at all the queues are i.i.d. with a general distribution. We are interested in the time D(k, n) required for all k customers to complete service from...

Much of Mathematics, and therefore Physics as well, have been limited by four rather consequential restrictions. Two of them are ancient taboos, one is an ancient and no longer felt as such bondage, and the fourth is a surprising omission in Algebra. The paper brings to the attention of those interested these four restrictions, as well as the fact that each of them has by now ways, even if hard...

The learning of Chinese has, for years, been regarded a s a matter that requires some special skill. At present there are still many people who have notbeen reached by the results of modern linguistic research and therefore they still look upon the learning of Chinese with the same attitude that Confucius had for the supernatural. When he was asked to give his opinion concerning it, Confucius s...

A comparative analysis of departures from multiple-locus Hardy-Weinberg equilibrium is presented for a set of four tribal Indian groups (the Yanomama, Makiritare, Wapishana and Ticuna) from the lowlands of South America. These tribes span a range of agglomeration and acculturation from the most traditional, swidden horticulturalists to frontier townspeople. The small-group social organization t...

For animals living in groups, one of the important questions is to understand what are the decisionmaking mechanisms that lead to choosing a motion direction or leaving an area while preserving group cohesion. Here, we analyse the initiation of collective departure in zebrafish Danio rerio. In particular, we observed groups of 2, 3, 5, 7 and 10 zebrafish swimming in a two resting sites arena an...

The bubble departures from two neighboring brass nozzles (with inner diameter of 1.1 mm) in three liquids: distilled water, mineral, and synthetic engine oils were investigated. numerical simulations used for reconstruction liquid-flow around the departing bubbles. Bubble movements liquid have been recorded using a high speed camera. 2-D paths reconstructed using: Laplacian Gaussian filters, al...

We apply Bayesian Linear Regression to estimate the response rate of drivers variable message signs at Seattle-Tacoma International Airport, or SEA. Our approach uses vehicle speed and flow data measured entrances arrival departure-ways airport terminal, sign data. Depending on time day, we that between 5.5 9.1% divert from departures arrivals when reads “departures full, use arrivals”, convers...

We present a positive political theory of criminal sentencing and test it using data from the United States Sentencing Commission. Under the U.S. Sentencing Guidelines, judges can use “offense-level adjustments” (fact-based decisionmaking) to lengthen or shorten the Guidelines’ presumptive sentences. Judges also can use “departures” from the Guidelines (law-based decisionmaking) to lengthen or ...

Red cell volumes in media sufficiently hypotonic to produce partial hemolysis have been measured with a high speed hematocrit and by an improved diffraction method. A comparison of the results shows that the upward departures from the linear relation based on the van't Hoff-Mariotte law are not observed when the volumes are measured diffractometrically. Downward departures are observed at low t...
