Schopenhauer\u27s Philosophy of Religion and his Critique of German Idealism

A significant but easily overlooked metaphilosophical theme in Schopenhauer’s corpus concerns the relationship between religion, philosophy, and “man’s need for metaphysics” (WWR II 162). I discuss the importance of this theme, and its attendant methodological commitments, for how we should understand Schopenhauer’s unique approach to global religious and mystical traditions. I demonstrate that explication of this theme provides a coherent, cogent way to identify and evaluate the substantive reasons, often unstated and which may otherwise appear to lack coherence or cogency, that underlie Schopenhauer’s criticism of philosophers associated with the tradition of German Idealism

Behavior of a bipartite system in a cavity

We study the time evolution of a superposition of product states of two dressed atoms in a spherical cavity in the situations of an arbitrarily large cavity (free space) and of a small one. In the large-cavity case, the system dissipates, whereas, for the small cavity, the system evolves in an oscillating way and never completely decays. We verify that the von Neumann entropy for such a system does not depend on time, nor on the size of the cavityComment: 9 pages 2 figures, Revtex, Version accepted to be published in Physical Review

Efeito da suplementação alimentar no ganho de peso de ovelhas criadas em pastagem de B. brizantha.

A ovinocultura pode tornar-se uma atividade altamente rentável para o Amazonas, contribuindo para o abastecimento de carne no mercado local. Entretanto, há uma extrema carência de informações e tecnologia que permitam à ovinocultura uma melhor eficiência, como por exemplo sobre o uso de suplementação alimentar, prática comum no Estado do Amazonas, usando produtos de baixo custo disponíveis no mercado local. Em função disto, realizou-se um ensaio objetivando avaliar o efeito da suplementação alimentar sobre o ganho de peso de ovelhas criadas a pasto. Para tanto, dois lotes de dez ovelhas com peso médio de 27 kg foram mantidos em um sistema de pastejo rotacionado sobre B. brizantha, sendo que um deles recebeu suplementação de 300g diárias de farelo de milho (33%), farelo de trigo (33%) e casquilho de soja (33%). O GMD obtido com a suplementação foi 43% superior, comprovando a eficácia desta prática local de suplementação e permitindo sua recomendação

Statistical properties of detrended fluctuation analysis

The main goal of this work is to consider the detrended fluctuation analysis (DFA), proposed by Peng et al. [Mosaic organization of DNA nucleotides, Phys. Rev. E. 49(5) (1994), 1685–1689]. This is a wellknown method for analysing the long-range dependence in non-stationary time series. Here we describe the DFA method and we prove its consistency and its exact distribution, based on the usual i.i.d. assumption, as an estimator for the fractional parameter d. In the literature it is well established that the nucleotide sequences present long-range dependence property. In this work, we analyse the long dependence property in view of the autoregressive moving average fractionally integrated ARFIMA(p, d, q) processes through the analysis of four nucleotide sequences. For estimating the fractional parameter d we consider the semiparametric regression method based on the periodogram function, in both classical and robust versions; the semiparametric R/S(n) method, proposed by Hurst [Long term storage in reservoirs, Trans. Am. Soc. Civil Eng. 116 (1986), 770–779] and the maximum likelihood method (see [R. Fox and M.S. Taqqu, Large-sample properties of parameter estimates for strongly dependent stationary Gaussian time series, Ann. Statist. 14 (1986), 517–532]), by considering the approximation suggested by Whittle [Hypothesis Testing in Time Series Analysis (1953), Hafner, New York]..info:eu-repo/semantics/publishedVersio

α-stable laws for noncoding regions in DNA sequences

In this work, we analyze the long-range dependence parameter for a nucleotide sequence in several different transformations. The long-range dependence parameter is estimated by the approximated maximum likelihood method, by a novel estimator based on the spectral envelope theory, by a regression method based on the periodogram function, and also by the detrended fluctuation analysis method. We study the length distribution of coding and noncoding regions for all Homo sapiens chromosomes available from the European Bioinformatics Institute. The parameter of the tail rate decay is estimated by the Hill estimator αˆ. We show that the tail rate decay is greater than 2 for coding regions, while for almost all noncoding regions it is less than 2.info:eu-repo/semantics/publishedVersio

Evidência de infecção ativa por herpesvírus 6 (variante- A) em pacientes com linfadenopatia em Belém, Pará, Brasil

A total of 323 patients with lymphadenopathy were selected in Belém, Brazil, between January 1996 and December 2001, and screened for the presence of human herpesvirus-6 (HHV-6) IgM- and- IgG antibodies by enzyme-linked immunosorbent assay (ELISA). When seroprevalence is analyzed by gender, similar rates are found for female (60.6%) and male (55.7%) individuals. Seventy-seven (23.8%) patients were HHV-6-IgM-and- IgG-positive (IgM+ subgroup), with positivity rates of 29.7% and 17.7% (p = 0.0007) for female- and male individuals, respectively. Sera from a subgroup (n = 120) of these subjects, with high HHV-6 antibody levels (either IgM+ or IgG+ reactivities), were subsequently processed for the presence of HHV-6 DNA by polymerase chain reaction (PCR)/nested PCR. Active infections (IgM+ and/or IgG+ high levels specific antibodies plus detection of viral DNA) were diagnosed in 20/77 (20.0%) and 8/43 (18.6%); subgroup of the 120 individuals suspected of having HHV-6 suggestive recent infection. All (n = 28) cases of active infection were found to be associated with HHV-6 variant-A (HHV-6A), as detectable by PCR/nested PCR, using variant-specific primer that amplify regions of 195 base pairs (bp) (HHV-6A) and 423 bp (HHV-6B). Rates of HHV-6 DNA detection between female and male patients were similar (p >; 0.05) in the IgM+ and IgG+ groups: 20.4% versus 35.7% and 25.0% versus 13.0%, respectively. HHV-6 DNA was detected across ; 50 age-groups at rates that ranged from 15.4% (male, ; 0,05) em pacientes dos sexos feminino e masculino, no grupo IgM+ e IgG+ com: 20,4% versus 35,7% e 25,0% versus 13,0%, respectivamente. A detecção do DNA viral do HHV-6 ocorreu no grupo etário ; 50 anos, com taxas que variaram de 15,4% (homens, < 5 anos) a 100,0% (mulheres, 11-20 anos). O aumento dos linfonodos cervicais foi registrado como mais freqüente, ocorrendo em número de 9 (32,0%) casos, tanto entre indivíduos do sexo masculino como naqueles do feminino. Entre os pacientes (n = 28) com infecção ativa pela variante A do HHV-6, a duração dos sintomas em 35,7% deles foi de 1-5 dias, enquanto em 64,3% durou de 6-20 dias. Nossos dados sugerem ser importante investigar a infecção pelo HHV-6 entre os pacientes (crianças e adultos) portadores de linfadenopatia como manifestação clínica proeminente no curso das doenças agudas febris

Early atypical malignant transformation of diffuse low-grade astrocytoma: The importance of genotyping

Diffuse astrocytoma (WHO grade II) has classically been considered a slow growing tumour, typically affecting young adults, with tendency for late malignant conversion. We describe a case of early atypical malignant transformation of diffuse astrocytoma seventeen months after complete surgical removal, as an intraventricular high-grade glioma (HGG). Retrospective laboratory findings for the presence of IDH 1/2 (isocitrate dehydrogenase) mutations were negative. There is growing evidence that IDH-wildtype (wt) astrocytomas behave more aggressively, therefore identifying IDH-mutation status should be mandatory in order to determine disease prognosis and guide treatment course.info:eu-repo/semantics/publishedVersio

Effect of age and anatomic site on likelihood of detecting S. aureus in pigs

Intensive sampling of two swine farms in Minnesota was conducted to obtain basic information about the ecology and epidemiology of S. aureus in modern multiple site swine production. The farms were selected by convenience, and two cohorts of animals were sampled in each system
