Music-Theoretic Estimation of Chords and Keys from Audio

This paper proposes a new method for local key and chord estimation from audio signals. This method relies primarily on principles from music theory, and does not require any training on a corpus of labelled audio files. A harmonic content of the musical piece is first extracted by computing a set of chroma vectors. A set of chord/key pairs is selected for every frame by correlation with fixed chord and key templates. An acyclic harmonic graph is constructed with these pairs as vertices, using a musical distance to weigh its edges. Finally, the sequences of chords and keys are obtained by finding the best path in the graph using dynamic programming. The proposed method allows a mutual chord and key estimation. It is evaluated on a corpus composed of Beatles songs for both the local key estimation and chord recognition tasks, as well as a larger corpus composed of songs taken from the Billboard dataset.

Wide Screening of Phage-Displayed Libraries Identifies Immune Targets in Planta

Microbe-Associated Molecular Patterns and virulence effectors are recognized by plants as a first step to mount a defence response against potential pathogens. This recognition involves a large family of extracellular membrane receptors and other immune proteins located in different sub-cellular compartments. We have used phage-display technology to express and select for Arabidopsis proteins able to bind bacterial pathogens. To rapidly identify microbe-bound phage, we developed a monitoring method based on microarrays. This combined strategy allowed for a genome-wide screening of plant proteins involved in pathogen perception. Two phage libraries for high-throughput selection were constructed from cDNA of plants infected with Pseudomonas aeruginosa PA14, or from combined samples of the virulent isolate DC3000 of Pseudomonas syringae pv. tomato and its avirulent variant avrRpt2. These three pathosystems represent different degrees in the specificity of plant-microbe interactions. Libraries cover up to 26107 different plant transcripts that can be displayed as functional proteins on the surface of T7 bacteriophage. A number of these were selected in a bio-panning assay for binding to Pseudomonas cells. Among the selected clones we isolated the ethylene response factor ATERF-1, which was able to bind the three bacterial strains in competition assays. ATERF-1 was rapidly exported from the nucleus upon infiltration of either alive or heat-killed Pseudomonas. Moreover, aterf-1 mutants exhibited enhanced susceptibility to infection. These findings suggest that ATERF-1 contains a microbe-recognition domain with a role in plant defence. To identify other putative pathogen-binding proteins on a genome-wide scale, the copy number of selected-vs.-total clones was compared by hybridizing phage cDNAs with Arabidopsis microarrays. Microarray analysis revealed a set of 472 candidates with significant fold change. Within this set defence-related genes, including well-known targets of bacterial effectors, are over-represented. Other genes non-previously related to defence can be associated through this study with general or strain-specific recognition of Pseudomonas.

Grants for Libraries

More and more libraries, museums and cultural institutions rely on fundraising and grant writing to sustain their services, special projects, or new initiatives Since most MLIS programs do not include grant project planning and proposal writing as part of their curriculum, librarians learn the process through trial and error, or continuing education classes. There are numerous books and websites that can assist the novice grant writer. We hope to provide beginners with basic information on the types of grants available, where to look for funding agencies, selected grant writing resources, and a few helpful grant writing hints to get you started. The presentation will be a three-person panel providing a short overview of the areas mentioned above, and discussion of sample grants submitted or received. The overview will be presented in Power Point format with an accompanying handout for each attendee.

Livros, folhetos, jornais, calendários e folhinhas, tudo à venda na botica de Padre Tezinho: práticas sociais e práticas de leitura nos anúncios dos jornais do século XIX (1820-1831)

Este é o resultado de um trabalho desenvolvido que compõe a tese de doutorado cujo tema está focado nas práticas de leitura presentes na sociedade maranhense no século XIX, com recorte entre os anos de 1821 a 1831, data da circulação do primeiro jornal e da instalação da primeira tipografia no Maranhão, estendendo-se por todo o Primeiro Reinado quando a província começou a vivenciar os debates políticos e as transformações sociais, culturais e econômicas que lhe proporcionaram a construção de uma nova identidade. Trata- se de uma investigação histórica, tendo como fonte principal de pesquisa os jornais que circularam no Maranhão nesse período, e como sustentabilidade os reclames neles publicados que forneceram pistas necessárias para o entendimento das questões suscitadas sobre a cultura escrita, principalmente a presença de protocolos de leitura que, de forma geral, circundam ou estão vinculados às práticas de leitura e à cultura e de modo singular às pessoas, a fim de identificar as relações estabelecidas na tríade livro-leitor-leitura e, consequentemente, os desdobramentos sociais e pessoais, a partir do que era lido, produzido, veiculado ou comercializado entre os habitantes da província. Assim, houve também uma investigação de práticas sociais, incluindo ações, sujeitos e relações sociais, instrumentos, objetos, valores, tempo e lugar, não haurindo absolutamente o passado, mas garimpando referenciais que auxiliaram a entender o presente. O texto refaz um pouco a trajetória da imprensa no Maranhão, instituída com a finalidade de publicar o primeiro jornal maranhense O Conciliador do Maranhão, cujo caminho também é reconstituído assim como o dos demais jornais que circularam no período pesquisado, mostrando que eles serviram, não só para aclarar ideias, mas também para fazer brotar ideais liberalizantes. O capítulo-chave decorre das informações extraídas sobre os impressos produzidos pela imprensa local, os que estavam sendo comercializados pelo mercado maranhense, os que se encontravam no prelo local ou externo, os que se constituíam em leituras dos intelectuais e jornalistas, considerados principais construtores das práticas de leitura dos maranhenses oitocentistas. Um panorama das instituições mediadoras do livro e da leitura fecha o circuito percorrido, mostrando que as artes como a música, a pintura e o teatro serviram para delinear uma sociedade com peculiar formação crítica e que, as sociedades literárias, os gabinetes de leitura, as bibliotecas e as escolas públicas ou particulares, foram, de fato, verdadeiros baluartes da boa educação e da liberdade dos povos.

A poesia de Paul Auster

This thesis examines Paul Austers extremely neglected early work: his poetry. Five books were published: Unearth (1974), Wall writing (1976), Effigies (1977), Fragments from cold (1977) and Facing the music (1980), available only at antiquarians and restrective universities libraries in the United States, as well as at the New York Public Library. Studies around Austers poetic oeuvre are restricted to papers, reviews, translators introduction, and a thesis that focus on his poetry to produce new analyses and interpretations of Austers novelistic works. The aim of this thesis is to gather this scattered material and provide new parameters of study around his poetry. Divided into three chapters, the first one maps the literary magazines where Auster published his poems at first, the translations of his poems and critical fortune; the second examines Austers five books according to three specific topics authorship, language, I and other themes related to them; the third analyzes White Spaces, text considered by the author as the bridge that leads him to prose and in this thesis as a singular writing in which Auster consolidates his literary project, since poetry, previous to prose, yet to come. Maurice Blanchot, Karlheinz Stierle and, principally, Auster, lay the foundation of the investigation. Other theorists who contribute to the understanding of the subject will be called to build the sui generis comparativism put into effect here

Influence of music on the growth of koi carp, Cyprinus carpio (Pisces: Cyprindae)

An experiment was carried out to investigate the influence of music on the growth of Koi Carp (Cyprinus carpio) by subjecting the fish to music. Weekly growth in weight was recorded and used to calculate the growth rate and specific growth rate. The difference in growth between the control and experiment groups of fishes was statistically tested for significance. It was observed that the growth of fish subjected to music was significantly higher.
