Many molecular signals that represent hunger and satiety in the body have been identified, but relatively little is known about how these factors alter the nervous system to change behavior. Root et al. (2011) report that hunger modulates the sensitivity of specific olfactory sensory neurons in Drosophila and facilitates odor-search behavior.

Brown clustering, an unsupervised hierarchical clustering technique based on ngram mutual information, has proven useful in many NLP applications. However, most uses of Brown clustering employ the same default configuration; the appropriateness of this configuration has gone predominantly unexplored. Accordingly, we present information for practitioners on the behaviour of Brown clustering in o...

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...
