This paper explores a fully automatic knowledge-based method which performs the noun sense disambiguation relying only on the WordNet ontology. The basis of the method is the idea of conceptual density, that is, the correlation between the sense of a given word and its context. A new formula for calculating the conceptual density was proposed and was evaluated on the SemCor corpus. 1 An Extensi...

X-ray powder diffraction provides a direct analysis of phase abundance of portland cement clinkers and cements. The ASTM C01 (Cement) Committee formed a task group to investigate quantitative X-ray powder diffraction analysis that resulted in the ASTM C 1365 standard test for X-ray powder diffraction of portland cement clinker and portland cement. Estimates of test precision and bias are requir...

In econometric applications it is common that the exact form of a conditional expectation is unknown and having flexible functional forms can lead to improvements over a pre-specified functional form, especially if they nest some successful parametric economically-motivated forms. Series method offers exactly that by approximating the unknown function based on k basis functions, where k is allo...

a301 (VLA-3), a member of the integrin family of cell adhesion receptors, may function as a receptor for fibronectin, laminin, and collagen . A partial cDNA clone (2 .4 kb) for the human a3 subunit was selected from an endothelial cell Agtll cDNA library by specific antibody screening. Several overlapping cDNA clones were subsequently obtained, of a total length of 4.6 kb from various cDNA libr...

Objetive: To describe some epidemiological characteristics of malignant oral cancers in a population of the Oncology Portuguese Institute of Porto (IPO-PORTO). Methods: After consulting databases of the IPO-PORTO database, we selected all patients diagnosed with oral cancer (C00 to C06) between 1 January 2004 and 31 December 2009, with histological confirmation. Data were analyzed according dis...

We consider the motion of an overdamped particle in a force field in presence of an external, adiabatic noise. We propose a new fluctuation-dissipation relation for this open nonequilibrium system and calculate the adiabatic noiseinduced rate of escape of the particle over a barrier. PACS number(s) : 05.40.-a,02.50.Ey Typeset using REVTEX 1 The motion of a Brownian particle in a fluid was first...

introduction : although oral cancer is amenable for early detection, it often presents as advanced disease in many of patients. long-lasting ulcer or mucosal discoloration has been described as the key to an early diagnosis; however other symptoms may also exist. the present study aims to describe the frequency of the early symptoms in oral cancer patients, with a special focus on pain. materia...
