Fusion and singular vectors in A1{(1)} highest weight cyclic modules

We show how the interplay between the fusion formalism of conformal field theory and the Knizhnik--Zamolodchikov equation leads to explicit formulae for the singular vectors in the highest weight representations of A1{(1)}.Comment: 42 page

Cosmic Ray particle production

The status of some popular models to simulate hadronic and nuclear interactions at Cosmic Ray energies is reviewed. The models predict the rise of all the hadronic and nuclear cross sections with energy and a smooth (logarithmic) rise of average multiplicities, rapidity plateaus and average transverse momenta with the energy. The importance is stressed to put more effort into the models and especially a better understanding of the minijet component at the highest energies. Likewise, experimental data on particle production are needed at the highest possible energies, to guide the models.Comment: 13 pages, LATEX, espcrc2.sty, 21 figures included as ps file

Maritime narratives of prehistoric cyprus: seafaring as everyday practice

This paper considers the role of seafaring as an important aspect of everyday life in the communities of prehistoric Cyprus. The maritime capabilities developed by early seafarers enabled them to explore new lands and seas, tap new marine resources and make use of accessible coastal sites. Over the long term, the core activities of seafaring revolved around the exploitation of marine and coastal resources, the mobility of people and the transport and exchange of goods. On Cyprus, although we lack direct material evidence (e.g. shipwrecks, ship representations) before about 2000 BC, there is no question that beginning at least by the eleventh millennium Cal BC (Late Epipalaeolithic), early seafarers sailed between the nearby mainland and Cyprus, in all likelihood several times per year. In the long stretch of time—some 4000 years—between the Late Aceramic Neolithic and the onset of the Late Chalcolithic (ca. 6800–2700 Cal BC), most archaeologists passively accept the notion that the inhabitants of Cyprus turned their backs to the sea. In contrast, this study entertains the likelihood that Cyprus was never truly isolated from the sea, and considers maritime-related materials and practices during each era from the eleventh to the early second millennium Cal BC. In concluding, I present a broader picture of everything from rural anchorages to those invisible maritime behaviours that may help us better to understand seafaring as an everyday practice on Cyprus

The global gas and dust budget of the Large Magellanic Cloud: AGB stars and supernovae and the impact on the ISM evolution

‘The definitive version is available at: www3.interscience.wiley.com '. Copyright Blackwell / Royal Astronomical Society. DOI: 10.1111/j.1365-2966.2009.14743.xWe report on an analysis of the gas and dust budget in the interstellar medium (ISM) of the Large Magellanic Cloud (LMC). Recent observations from the Spitzer Space Telescope enable us to study the mid-infrared dust excess of asymptotic giant branch (AGB) stars in the LMC. This is the first time we can quantitatively assess the gas and dust input from AGB stars over a complete galaxy, fully based on observations. The integrated mass-loss rate over all intermediate and high mass-loss rate carbon-rich AGB candidates in the LMC is 8.5 × 10−3 M⊙ yr−1 , up to 2.1 × 10−2 M⊙ yr−1 . This number could be increased up to 2.7 × 10−2 M⊙ yr−1 if oxygen-rich stars are included. This is overall consistent with theoretical expectations, considering the star formation rate (SFR) when these low- and intermediate-mass stars where formed, and the initial mass functions. AGB stars are one of the most important gas sources in the LMC, with supernovae (SNe), which produces about 2–4 × 10−2 M⊙ yr−1 . At the moment, the SFR exceeds the gas feedback from AGB stars and SNe in the LMC, and the current star formation depends on gas already present in the ISM. This suggests that as the gas in the ISM is exhausted, the SFR will eventually decline in the LMC, unless gas is supplied externally. Our estimates suggest 'a missing dust-mass problem' in the LMC, which is similarly found in high-z galaxies: the accumulated dust mass from AGB stars and possibly SNe over the dust lifetime (400–800 Myr) is significant less than the dust mass in the ISM. Another dust source is required, possibly related to star-forming regions.Peer reviewe

Comparative genomics provides insights into the lifestyle and reveals functional heterogeneity of dark septate endophytic fungi

Dark septate endophytes (DSE) are a form-group of root endophytic fungi with elusive functions. Here, the genomes of two common DSE of semiarid areas, Cadophora sp. and Periconia macrospinosa were sequenced and analyzed with another 32 ascomycetes of different lifestyles. Cadophora sp. (Helotiales) and P. macrospinosa (Pleosporales) have genomes of 70.46 Mb and 54.99 Mb with 22,766 and 18,750 gene models, respectively. The majority of DSE-specific protein clusters lack functional annotation with no similarity to characterized proteins, implying that they have evolved unique genetic innovations. Both DSE possess an expanded number of carbohydrate active enzymes (CAZymes), including plant cell wall degrading enzymes (PCWDEs). Those were similar in three other DSE, and contributed a signal for the separation of root endophytes in principal component analyses of CAZymes, indicating shared genomic traits of DSE fungi. Number of secreted proteases and lipases, aquaporins, and genes linked to melanin synthesis were also relatively high in our fungi. In spite of certain similarities between our two DSE, we observed low levels of convergence in their gene family evolution. This suggests that, despite originating from the same habitat, these two fungi evolved along different evolutionary trajectories and display considerable functional differences within the endophytic lifestyle

Low Rates of HIV Testing Among Adults With Severe Mental Illness Receiving Care in Community Mental Health Settings

OBJECTIVE: This research aimed to characterize HIV testing rates among Medicaid recipients with severe mental illness who received public specialty mental health services. METHODS: This retrospective cohort study examined California Medicaid records from October 1, 2010, to September 30, 2011 (N=56,895). Study participants were between age 18 and 67, utilized specialty mental health care services, were prescribed antipsychotic medications, and were not dually eligible for Medicare. Adjusted Poisson regression models were used to estimate the overall effects of predictor variables on HIV testing prevalence. RESULTS: During the study period, 6.7% of people with severe mental illness received HIV testing. Men were 32% less likely to be tested for HIV than women (p,.001). Compared with whites, Asians/Pacific Islanders were 53% less likely and blacks were 82% more likely to be tested (p,.001). Those with comorbid drug or alcohol use disorders were more likely to be tested than those without such disorders (p,.001). Utilization of non-psychiatric medical care was the strongest predictor of HIV testing (p,.001). CONCLUSIONS: Most adults with severe mental illness receiving public specialty mental health services were not tested for HIV during a one-year period. Public health administrators must prioritize HIV testing for early identification of HIV infection and prevention of HIV transmission
