Evidence of the selection of tidal streams by northern rock sole (Lepidopsetta polyxystra) for transport in the eastern Bering Sea

Depth data from archival tags on northern rock sole (Lepidopsetta polyxystra) were examined to assess whether fish used tidal currents to aid horizontal migration. Two northern rock sole, out of 115 released with archival tags in the eastern Bering Sea, were recovered 314 and 667 days after release. Both fish made periodic excursions away from the bottom during mostly night-time hours, but also during particular phases of the tide cycle. One fish that was captured and released in an area of rotary currents made vertical excursions that were correlated with tidal current direction. To test the hypothesis that the fish made vertical excursions to use tidal currents to aid migration, a hypothetical migratory path was calculated using a tide model to predict the current direction and speed during periods when the fish was off the bottom. This migration included limited movements from July through December, followed by a 200-km southern migration from January through February, then a return northward in March and April. The successful application of tidal current information to predict a horizontal migratory path not only provides evidence of selective tidal stream transport but indicates that vertical excursions were conducted primarily to assist horizontal migration

Expanded Bases of Jurisdiction -- An Examination of Tennessee\u27s New Long-Arm Statute

A foreign corporation considering the consequences of its activity in relation to forums outside the state of its incorporation is faced with three basic legal problems. They are generally regarded as the different degrees of doing business for purposes of (1) qualification,(2) taxation, and (3) judicial jurisdiction. The purpose of this paper is to discuss a major recent development concerning the jurisdiction of Tennessee courts, in light of similar developments throughout the country

A Search for X-Ray Bright Distant Clusters of Galaxies

We present the results of a search for X--ray luminous distant clusters of galaxies. We found extended X--ray emission characteristic of a cluster towards two of our candidate clusters of galaxies. They both have a luminosity in the ROSAT bandpass of $\simeq10^{44}{\rm \,erg\,s^{-1}}$ and a redshift of $>0.5$; thus making them two of the most distant X--ray clusters ever observed. Furthermore, we show that both clusters are optically rich and have a known radio source associated with them. We compare our result with other recent searches for distant X--ray luminous clusters and present a lower limit of $1.2\times10^{-7}\,{\rm Mpc^{-3}}$ for the number density of such high redshift clusters. This limit is consistent with the expected abundance of such clusters in a standard (b=2) Cold Dark Matter Universe. Finally, our clusters provide important high redshift targets for further study into the origin and evolution of massive clusters of galaxies.

Balancing International Aspirations with Honors Expectations: Expanding Honors to a Branch Campus in Florence, Italy

Education abroad has the potential to leave a deep and transformative impact on the lives of honors students. That education abroad and a broader focus on the larger world beyond the boundaries of campuses comprises a core value of many honors programs and colleges comes as no surprise. In addition to providing a rigorous education and undergraduate research opportunities, many honors programs aspire to making their students more cosmopolitan in their worldview. The philosopher Kwame Anthony Appiah explains that cosmopolitanism blends two important values: it stretches us “beyond those to whom we are related by the ties of kith and kind, and even the more formal ties of a shared citizenship,” and helps us recognize that “[p]eople are different . . . and there is much to learn from our differences” (xv). Cosmopolitanism has intrinsic and extrinsic value for honors students and indeed for all students studying abroad. Studying abroad exposes students to art, languages, philosophies, and cultures that can enrich their understanding of the range of human expression and ideas, and they learn important lessons about their own humanity and the world around them. On its own terms, this engagement with an increasingly complex world, opens their eyes to relevant and living alternatives to many of the beliefs and practices they embrace, often only through the force of custom, habit, or convenience. Education abroad also has an instrumental purpose in building and sharpening essential intellectual and interpersonal skills that play a critical role in students’ academic, personal, and professional development (Dwyer; Dwyer and Peters). While abroad, students may develop important critical reasoning skills and intellectual virtues (Nguyen), as well as greater confidence, maturity, empathy, and creativity (Gray et al.; Maddux and Galinsky). International experiences are also linked to the honors thesis project in unexpected but significant ways, and they sometimes alter career paths and graduate degrees pursued after graduation (Markus et al.). Finally, education abroad uniquely prepares students to compete for selective international post-graduate opportunities, including the Fulbright Student Program and the Marshall and Rhodes scholarships. These benefits appear to impact students positively long after graduation (Mulvaney, “Long-Term Impact”—also reprinted in this volume)

Liveweight Gain of Lambs Grazing Six Short-Term Ryegrass Cultivars

Increasing dry matter (DM) production per ha is a key goal in ryegrass (Lolium) breeding programmes (Easton et al., 2002), based on the assumption that increased DM yield will in turn increase profitability per ha, through an increase in animal productivity. However, the performance of animals grazing pasture can also be modified by the quality of the forage on offer, and the presence of toxins within the pasture. The objective of this study was to compare the liveweight gain per hectare of lambs grazing six short-term ryegrasses, which had been selected for various combinations of improved DM production and nutritive value

Building a Sentiment Corpus of Tweets in Brazilian Portuguese

The large amount of data available in social media, forums and websites motivates researches in several areas of Natural Language Processing, such as sentiment analysis. The popularity of the area due to its subjective and semantic characteristics motivates research on novel methods and approaches for classification. Hence, there is a high demand for datasets on different domains and different languages. This paper introduces TweetSentBR, a sentiment corpora for Brazilian Portuguese manually annotated with 15.000 sentences on TV show domain. The sentences were labeled in three classes (positive, neutral and negative) by seven annotators, following literature guidelines for ensuring reliability on the annotation. We also ran baseline experiments on polarity classification using three machine learning methods, reaching 80.99% on F-Measure and 82.06% on accuracy in binary classification, and 59.85% F-Measure and 64.62% on accuracy on three point classification.Comment: Accepted for publication in 11th International Conference on Language Resources and Evaluation (LREC 2018

A short response-time atomic source for trapped ion experiments

Ion traps are often loaded from atomic beams produced by resistively heated ovens. We demonstrate an atomic oven which has been designed for fast control of the atomic flux density and reproducible construction. We study the limiting time constants of the system and, in tests with $^{40}\textrm{Ca}$, show we can reach the desired level of flux in 12s, with no overshoot. Our results indicate that it may be possible to achieve an even faster response by applying an appropriate one-off heat treatment to the oven before it is used.Comment: 5 pages, 7 figure

The Las Campanas Distant Cluster Survey -- The Correlation Function

We present the first non-local (z>0.2) measurement of the cluster-cluster spatial correlation length, using data from the Las Campanas Distant Cluster Survey (LCDCS). We measure the angular correlation function for velocity-dispersion limited subsamples of the catalog at estimated redshifts of 0.35<z_{est}<0.575, and derive spatial correlation lengths for these clusters via the cosmological Limber equation. The correlation lengths that we measure for clusters in the LCDCS are consistent both with local results for the APM cluster catalog and with theoretical expectations based upon the Virgo Consortium Hubble Volume simulations and the analytic predictions. Despite samples containing over 100 clusters, our ability to discriminate between cosmological models is limited because of statistical uncertainty.Comment: 7 pages, 4 figures, accepted to ApJ (v571, May 20, 2002
