Two theoretical formalisms are widely used in modeling mechanochemical systems such as protein motors: continuum Fokker-Planck models and discrete kinetic models. Both have advantages and disadvantages. Here we present a "finite volume" procedure to solve Fokker-Planck equations. The procedure relates the continuum equations to a discrete mechanochemical kinetic model while retaining many of th...

The aim of this study was to evaluate MHC class I expression and prognosis using tumor tissues surgically removed from 9 dogs with mammary gland carcinomas and from 13 dogs with complex carcinomas. We assessed MHC class I expression and its correlation with tumor size, B2M expression, infiltration of lymphocytes, histological grade and prognosis. Hematoxylin and eosin-stained sections were hist...

BACKGROUND Neuroendocrine (NE) carcinomas of the breast are defined by the diffuse expression of NE markers. This definition includes lesions with 'pure' NE phenotype as well as 'variants' which may co-express mucinous and/or apocrine phenotype. In the present work, the clinical significance of pure' NE differentiation in breast carcinoma and of its 'variants' will be analyzed. MATERIALS AND ...

lipid rich carcinoma is rare in dog and women and is characterized by cells that have an abundant foamy cytoplasm. a 10 year old, mix breed female dog suffered two subcutaneous masses in ventral abdomen was referred to surgery department of veterinary hospital of ahvaz shahid chamran university. surgical excision and microscopic examination of masses were done. after grading by elston and ellis...

In the current stage over 85% of world energy demand is supplied by fossil fuels. Coal-fired plants discharged roughly 40% of the total CO2 are the main contributors in CO2 emissions (Kim & Kim, 2004; Yang et al., 2008). Environmental issues caused by exhaust green house gases (GHG) and toxics have become global problems. Through the past studies of five decades, increased GHG levels in atmosph...

Greek dysmorphia, meaning ugliness (expressly of the face) was first coined by Morselli in the late19th century. He described a subjective feeling of a physical defect which the patient feels is noticeable to others, although his appearance is within normal limits. Dysmorphophobia first appeared in the US psychiatric nosology (as an atypical somatoform disorder) in 1980, with the publication of...

Theoretical understanding of the generation and growth of wind driven surface water waves has been based on two distinct mechanisms; the first being stochastic excitation by wave incoherent random atmospheric pressure fluctuations unrelated to wave amplitude (Eckart 1953; Phillips 1957) and the second instability arising from wave induced coherent atmospheric pressure fluctuations proportional ...

O video repositories are becoming more common as we enter the era of digital video. As the number, size, and accessibility of digital video repositories grows, so does the need for video storage and retrieval systems. Television news and entertainment operations in particular find themselves in need of solutions for storing and retrieving large amounts of digital video. The dilemma of what is o...

This paper investigates the abilities of Artificial Neural Networks (ANN), Least Squares – Support Vector Regression (LS-SVR), Fuzzy Logic, and Adaptive Neuro-Fuzzy Inference System (ANFIS) techniques to improve the accuracy of daily pan evaporation estimation in sub-tropical climates. Meteorological data from the Karso watershed in India (consisting of 3801 daily records from the year 2000 to ...
