Distribution of fishing effort and resulting tuna catches from the Eastern Tropical Pacific Ocean, by quarters of the year, 1959-1962
No full textENGLISH: This report is a sequel to one previously published by the Commission (Alverson, 1960) which covered the years 1951 through 1958. It is based entirely on information collected from the logbooks of purse-seiners and baitboats engaged in the fishery for yellowfin (Thunnus albacares) and skipjack (Katsuwonus pelamis) tuna in the Eastern Pacific from 1959 through 1962.

amarilla (Thunnus albacares) y del barrilete (Katsuwonus pelamis) en el Pacífico Oriental, desde 1959 a 1962

A little Higgs model with exact dark matter parity
No full textWe present a little Higgs model where a dark matter parity is implemented such that it is not violated by WZW terms present in strongly coupled UV-completions. We show how to consistently implement fermions into this setup and determine the low energy spectrum of the model. The lightest parity odd state is stable and a viable dark matter candidate. We briefly discuss experimental constraints on the model
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Search for WH associated production in 5.3 fb−1 of pp¯ collisions at the Fermilab Tevatron
No full textWe present a search for associated production of Higgs and W bosons in p¯p collisions at a center of mass energy of √ s = 1.96 TeV in 5.3 fb−1 of integrated luminosity recorded by the D0 experiment. Multivariate analysis techniques are applied to events containing one lepton, an imbalance in transverse energy, and one or two b-tagged jets to discriminate a potential WH signal from Standard Model backgrounds. We observe good agreement between data and expected backgrounds, and set an upper limit of 4.5 (at 95% confidence level and for mH = 115 GeV) on the ratio of the WH cross section multiplied by the branching fraction of H →b¯b to its Standard Model prediction, which is consistent with an expected limit of 4.8
