Abstract: Aims: To evaluate the clinical stage at diagnosis of prostate cancer. Materials and Methods: This study was retrospective and?descriptive from January 2008 to June 2013. Patients who were diagnosed with prostate cancer wereinvolved and confirmed by clinical examination anatomopathological screening. They also realized a total serum PSA, a bladder-prostatic and abdominal ultrasound. Results: Average age was seventy years, ranging from fifty years to seventy years. The general status of our patients was satisfactory in 78% of cases. Main symptoms were dysuria and frequencyin 96% and 86%, respectively. Family past history of prostate cancer were found in 24% of cases. Twenty-three patients (43%) had a total serum PSA ≥ 100 ng/ml. Adenocarcinoma was the main histological type. Grades 1 and 4 were the most frequent. Thirty-three patients (66%) had a Gleasonscore betwen [2]-[6]. Forty-four patients (88%) had locally advanced and metastatic desease. The D’Amico score was identified in six patients but 3 and 2 patients were low risk and intermediate riskrespectively. Finally, 1 patient was high risk. Conclusion: Prostate cancer remains elderly man cancer. It was discovered in locally advanced and metastatic desease in this series. This diagnosis was late in the majority of cases.
Image Analaysis Coupled With A SEM-EDS Applied To The Characaterization Of A Zn-Pb Partially Weathered Ore  [PDF]

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2002, DOI: 10.4236/jmmce.2002.11001
Abstract: The image analysis coupled with Energy Dispersive Spectrometry (EDS) analysis on a Scanning Electron Microscope (SEM) was applied to the characterization of a Zn and Pb ore as an efficient tool for mineral quantification and for the assessment of the degree of mineral liberation. Screened size fractions of mineral particles were mounted on polished thin sections and, later on, analyzed by a SEM coupled with an EDS. This is important for the discrimination of different mineral phases, particularly when two minerals have similar average atomic numbers, such as willemite and pyrite. Two images per field were collected - backscattered electrons image and a multi-element X-ray dot mapping images. The results were utilized for quantification and liberation analysis of two valuable minerals in the ore -sphalerite and galena.

Abstract: Reading and writing research indicates that students do both activities more successfully if the process that readers and writers engage in is consciously activated to aid in the production of products. In writing instruction, this has led to a focus on facilitating the composing process through the introduction of pre-writing, composing, revising, and editing activities. Currently the same types of strategies are available to facilitate the reading process. Many of these, developed by individual teachers or projects such as the California Literature Project, aim to help students read challenging materials in their first language.

AdS3 Gravitational Instantons from Conformal Field Theory
S. Mano
Physics , 1999, DOI: 10.1142/S0217732399002030
Abstract: A conformal field theory on the boundary of three-dimensional asymptotic anti-de Sitter spaces which appear as near horizon geometry of D-brane bound states is discussed. It is shown that partition functions of gravitational instantons appear as high and low temperature limits of the partition function of the conformal field theory. The result reproduces phase transition between the anti-de Sitter space and the BTZ black hole in the bulk gravity.
Duality, Ancestral and Diffusion Processes in Models with Selection
Shuhei Mano
Mathematics , 2008,
Abstract: The ancestral selection graph in population genetics was introduced by KroneNeuhauser (1997) as an analogue of the coalescent genealogy of a sample of genes from a neutrally evolving population. The number of particles in this graph, followed backwards in time, is a birth and death process with quadratic death and linear birth rates. In this paper an explicit form of the probability distribution of the number of particles is obtained by using the density of the allele frequency in the corresponding diffusion model obtained by Kimura (1955). It is shown that the process of fixation of the allele in the diffusion model corresponds to convergence of the ancestral process to its stationary measure. The time to fixation of the allele conditional on fixation is studied in terms of the ancestral process.
Ancestral Graph with Bias in Gene Conversion
Shuhei Mano
Mathematics , 2009,
Abstract: Gene conversion is a mechanism by which a double-strand break in a DNA molecule is repaired using a homologous DNA molecule as a template. As a result, one gene is 'copied and pasted' onto the other gene. It was recently reported that the direction of gene conversion appears to be biased towards G and C nucleotides. In this paper a stochastic model of the dynamics of the bias in gene conversion is developed for a finite population of members in a multigene family. The dual process is the biased voter model, which generates an ancestral random graph for a given sample. An importance-sampling algorithm for computing the likelihood of the sample is also given.
Duality between the two-locus Wright-Fisher Diffusion Model and the Ancestral Process with Recombination

Quantitative Biology , 2012,
Abstract: Known results on the moments of the distribution generated by the two-locus Wright-Fisher diffusion model and a duality between the diffusion process and the ancestral process with recombination are briefly summarized. A numerical methods for computing moments by a Markov chain Monte Carlo and a method to compute closed-form expressions of the moments are presented. By using the duality argument properties of the ancestral recombination graph are studied in terms of the moments.
Extreme sizes in the Gibbs-type exchangeable random partitions
Shuhei Mano
Statistics , 2013,
Abstract: Gibbs-type exchangeable random partitions, which is a class of multiplicative measures on the set of positive integer partitions, appear in various contexts, including Bayesian statistics, random combinatorial structures, and stochastic models of diversity in various phenomena. Some distributional results on ordered sizes in the Gibbs partition are established by introducing associated partial Bell polynomials and analysis of the generating functions. The combinatorial approach is applied to derive explicit results on asymptotic behavior of the extreme sizes in the Gibbs partition. Especially, Ewens-Pitman partition, which is the sample from the Poisson-Dirichlet process and has been discussed from rather model-specific viewpoints, and a random partition which was recently introduced by Gnedin, are discussed in the details. As by-products, some formulas for the associated partial Bell polynomials are presented.
