Reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. In fact, determination of permeability is a crucial task in reserve estimation, production and development. Traditional methods for permeability prediction are well log and core data analysis which are very expensive and time-consuming. Well log data is an alternative approach for prediction of pe...

Recurrent hepatitis C after orthotopic liver transplantation (OLT) is universal and can lead to graft failure and, consequently, reduced survival. Hepatitis C treatment can be used to prevent these detrimental outcomes. The aim of this study was to describe rates of hepatitis C recurrence and sustained virological response (SVR) to interferon-based treatment after OLT and its relationship to su...

Due to the inherent non-linearity and non-stationary characteristics of financial stock market price time series, conventional modeling techniques such as the Box–Jenkins autoregressive integrated moving average (ARIMA) are not adequate for stock market price forecasting. In this paper, a forecasting model based on chaotic mapping, firefly algorithm, and support vector regression (SVR) is propo...

The life expectancy and load capacity of oil-immersed power transformers are intimately associated with the winding hot spot temperature (HST). Thus, accurately predicting HSTs is essential in evaluating the life expectancy of power transformers and in preventing thermal failure. Previously, support vector machine (SVM) has been successfully employed to solve the regression problem of nonlinear...

BACKGROUND Genetic variation in IL28B and other factors are associated with sustained virological response (SVR) after pegylated-interferon/ribavirin treatment for chronic hepatitis C (CHC). Using data from the HALT-C Trial, we developed a model to predict a patient's probability of SVR based on IL28B genotype and clinical variables. METHODS HALT-C enrolled patients with advanced CHC who had ...

BACKGROUND/AIMS Lipid profile and insulin resistance (IR) are associated with hepatitis C virus (HCV) and may predict the chronic hepatitis C (CHC) treatment response. The aim of this study was to determine the association between CHC treatment response and lipid profile and IR change during treatment. METHODS In total, 203 CHC patients were reviewed retrospectively between January 2005 and D...

OBJECTIVE: To determine the frequency and prognosis of the various causes of low systemic vascular resistance (SVR). DESIGN: Analysis of consecutive patients over a 5-year period; retrospective review. SETTING: Medical intensive care unit of a large university hospital. PATIENTS: Fifty-five patients with unexplained hypotension and a SVR less than 800 dynes x s/cm5. BACKGROUND: There are minima...

Protein structure prediction is an important problem of both intellectual and practical interest. Most protein structure prediction approaches generate multiple candidate models first, and then use a scoring function to select the best model among these candidates. In this work, we develop a scoring function using support vector regression (SVR). Both consensus-based features and features from ...

Cortical evoked response audiometry is adequate for approximating hearing threshold levels with frequency specificity when the psychoacoustic responses lack reliability and reproducibility (compensation claim). It is well-known that control of wakefulness is essential for the reliability of slow vertex responses (SVR). Therefore, sedative, hypnotic, and neuroleptic drugs are supposed to have po...

Single nucleotide polymorphisms (SNPs) rs12979860 and rs8099917 near the interleukin 28B gene are predictors of virological response (SVR) to IFN-based therapy for monoinfected chronic hepatitis C patients. We retrospectively evaluated the impact of IL28B SNPs and other factors on SVR in a cohort of 102 HIV-1/HCV-coinfected patients treated with pegylated interferon-? (peg-INF?) and ribavirin. ...
