This paper introduces an effective production optimization and a water injection allocation method for oil reservoirs with water injection. In this method, a two-stage adaptive simulated annealing (ASA) is used. A coarse-grid model is made based on average horizon permeability at the beginning iterations of the optimization to search quickly. In the second stage, the fine-grid model is used to ...

Most of people knows the following problem, What is the next term ? What expression would give us the general term ? It would be nice to have a formula to generate all the terms in the sequence. how do we find the formula? here is the way to become a 'genius' at MENSA tests.

We discuss combining knowledge-based (or rule-based) and statistical part-of-speech taggers. We use two mature taggers, ENGCG and Xerox Tagger, to independently tag the same text and combine the results to produce a fully disambiguated text. In a 27000 word test sample taken from a previously unseen corpus we achieve 98.5 % accuracy. This paper presents the data in detail. We describe the probl...

Multiple-choice tests play a large role in determining academic and professional outcomes. Performance on these tests hinges not only on a test-taker’s knowledge of the material but also on his willingness to guess when unsure about the answer. In this paper, we present the results of an experiment that explores whether women skip more questions than men. The experimental test consists of pract...

In this issue of Cell, Coppens and coworkers (Coppens et al., 2006) describe how Toxoplasma gondii, an obligate intracellular parasite, feeds on the host. Coppens et al. provide evidence that the parasite takes host cell endosomes and lysosomes hostage by sequestering them where the parasite resides, within invaginations of the parasitophorous vacuole.
