Perturbative analysis of the Neuberger-Dirac operator in the Schr\"odinger functional

We investigate the spectrum of the free Neuberger-Dirac operator \Dov on the Schr\"odinger functional (SF). We check that the lowest few eigen-values of the Hermitian operator \Dov^{\dag}\Dov in unit of $L^{-2}$ converge to the continuum limit properly. We also perform a one-loop calculation of the SF coupling, and then check the universality and investigate lattice artifacts of the step scaling function. It turns out that the lattice artifacts for the Neuberger-Dirac operator are comparable in those of the clover action.Comment: 22 pages 5 figure

Avaliação de descritores morfológicos de folha e flor em acessos de melancia.

O presente trabalho objetivou avaliar descritores morfológicos de folha e flor, em acessos de melancia. O experimento foi realizado no campo experimental da Embrapa Rondônia, localizado em Porto Velho ? RO. Os tratamentos foram compostos pelas c ultivares ?Charleston Gray?, ?Sugar Baby?, ?Kodama? e por 15 acessos da coleção ativa de germoplasma da Embrapa Semiárido. Empregou-se o delineamento de blocos casualizados com três repetições e parcelas de seis plantas. Em cada parcela foram amostradas cinco folhas, cinco flores masculinas e cinco flores femininas para determinação da largura e comprimento foliar (LFH e CFH); relação CFH/LFH; diâmetro da corola em flores masculinas (DCM) e femininas (DCF); diâmetro e comprimento do ovário (DOV e COV) e relação COV/DOV. Os dados foram submetidos à análise de variância e as médias foram comparadas por meio do teste de Scott & Knott. As variáveis LFH, CFH, CFH/LFH, DCM, DCF, DOV, COV, COV/DOV apresentaram, respectivamente, as seguintes médias: 19,19 cm, 21,18 cm; 1,11; 3,06 cm; 2,37 cm; 0,86 cm; 1,25 cm e 1,48. Foram verificadas diferenças significativas entre os tratamentos apenas para as variáveis DCF, DOV, COV e COV/DOV, indicando que a folha e a flor masculina não foram descritores apropriados para a caracterização do germoplasma avaliado. lanatu

Are We Legislating Away Our Scientific Future? The Database Debate

The ambiguity of the present copyright laws governing the protection of databases creates a situation where database owners, unsure of how IP laws safeguard their information, overprotect their data with oppressive licenses and technological mechanisms (condoned by the DMCA) that impede interoperation. Databases are fundamental to scientific research, yet the lack of interoperability between databases and limited access inhibits this research. The US Congress, spurred by the European Database Directive, and heavily lobbied by the commercial database industry, is presently considering ways to legislate database protections; most of the present suggestions for legislation will be detrimental to scientific progress. The author agrees that new legislation is necessary, but not to provide extra-copyright protections, as database owners would like, but to create an environment wherein data is easily accessible to academic research and interoperability is encouraged; yet simultaneously providing database owners with incentives to produce new databases. One possibility would be to introduce standardized compulsory licensing of databases to academics following an embargo period where databases could be sold at free-market prices (to recoup costs). Databases would be given some sort of intellectual property protection both during and after this embargo in return for a limiting of technical safeguards and conforming to interoperability standards

Development of limited water resources : historical and technological aspects

This review describes how the constraints of limited water resources and an arid and semi-arid environment were overcome by a leadership capable of defining future needs and identifying and implementing appropriate solutions. Advanced technologies proved indispensable in this process. Yet, in recent years, the continuously increasing demand for water, mainly for domestic use, has created a chronic situation in which all available water from natural sources is being used up. The only solution to ensuring a dependable supply of water for both domestic and agricultural use requires that several steps be taken concurrently to implement regulations and measures for saving water and to construct immediately large-scale plants for desalination of seawater and reclamation of urban effluents

Obituary: Dov Noy (1920-2013)

Dov Noy was my teacher, but not mine alone. He introduced folklore into Jewish Studies, and Jewish folklore into the discipline of folklore. Stith Thompson (1885-1976) integrated Dov Noy\u27s dissertation (as Dov Neuman) Motif-Index of Talmudic-Midrashic Literature (1954) into the second edition of the Motif-Index of Folk-Literature and established its subject, and Dov Noy himself, firmly in the international community of folklore scholars. Upon the completion of his studies at Indiana University, Noy joined the faculty of the Hebrew University in Jerusalem in 1955 and began offering courses in folklore in the Hebrew Literature and the Yiddish departments. He was an inspirational teacher who attracted students and motivated them to continue the systematic research and teaching of Jewish folklore, and they have done so at the Hebrew University and in other Israeli universities. He himself taught Jewish folklore in American and Canadian universities, and inspired scholars, writers, and storytellers to explore and revive the art of storytelling in Jewish societies

Dov Kam, transcript only

Transcript of an interview with Dov Kam by Lucille Brown of Union College. Dov\u27s official name was Sam Berko Kam but he changed it because he came to America as a stowaway. He was born in 1895 in Porazava in Russia.https://digitalworks.union.edu/berkoralhistories/1029/thumbnail.jp
