We propose to model breast tissue in mammograms covering both density and tissue patterns. The breast tissue density modelling is based on the global density distribution of the breast region. We segment the whole breast region into a number of uniform density sub-regions and construct an overall density model of the breast using the relative proportions of these sub-regions. The breast tissue ...

epilepsy is one of the most common neuroinflammatory disorders that affect more than 50 million people worldwide. excessive electrical discharges in neurons following neural cell damage or loss leads to recurrent seizures, which are described as epilepsy. one of the most common and difficult to treat types of epilepsy is temporal lobe epilepsy (tle), which results from hippocampal sclerosis. cu...

The MV/LV transformer without a tank in the underground substation can produce remarkable interference with the computer Cathode-Ray Tube (CRT) displayers above the ground, because of the generated power frequency magnetic field. To resolve such problem, a tank with high conductivity or/and high permeability is needed to enclose the transformer. To evaluate the shielding effectiveness, the fini...

introduction : shared neuropathology hypothesis in schizophrenia and temporal lobe epilepsy has been introduced long term ago. similar neuropathology leads to the analogous clinical features like neuropsychological features as an example. the aim of this study was to examine this hypothesis by the means of comparing neuropsychological functions in these two patient groups. method : present stud...

the aim of the present study was to investigate the effect of gender on the distribution of pancreatic islets in native chicken. ten adult male and ten adult female isfahan native chickens were used in this experiment. results showed a distinct sexual dimorphism in the native chicken pancreas which depends upon the various fractions of the pancreatic lobes, which were occupied by alpha, beta an...

background and objective: temporal lobe epilepsy (tle) is a chronic neurological disorder with spontaneous recurrent seizures and abnormal intracranial waves. since the role of oxidative stress in the occurrence of epilepsy is inevitable, it seems that the use of antioxidants can prevent some of the complications resulting from this disease. this study was designed to assess the protective effe...

in this paper, a method based on binary-coded genetic algorithm is proposed to explore an optimization method, for obtaining an optimal elliptical tank. this optimization method enhances the rollover threshold of a tank vehicle, especially under partial filling conditions. minimizing the overturning moment imposed on the vehicle due to c.g. height of the liquid load, lateral acceleration and ca...

Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...
