Modern challenges of food science require a new understanding of the determinants of food quality and safety. Application of advanced imaging modalities such as magnetic resonance imaging (MRI) has seen impressive successes and fast growth over the past decade. Since MRI does not have any harmful ionizing radiation, it can be considered as a magnificent tool for the quality control of food prod...

introduction: the use of high-cost and high-tech magnetic resonance imaging (mri) has expanded over the past decade. a recently conducted research reported various causes with regard to their own country and healthcare system included aging population and advances in diagnostic technologies which could result in diagnostic services to become more applicable in clinical arena. increasing number ...

Abstract Background Cerebral neoplasm arises from brain, spinal cord and meningeal cells. Not only malignant cerebral neoplasm also benign tumor could lead to death due to mass effect on vital structures. Access to these tumors is difficult, and MRI and CT scan could be helpful in determining anatomical location of tumors and distinction of malignant from benign. Objective For better and ea...

The soak-time of vehicle trip starts is defined as the duration of time in which the vehicle’s engine is not operating and that precedes a successful vehicle start. The temporal distribution of the soak-time in an area is an important determinant of area-wide mobile source emissions. In the current paper, we formulate and implement a methodology for modeling soak-time durations. The methodology...

In this paper, we present an evaluation of seven automatic brain tissue classifiers based on level of agreements. A number of agreement measures are explained, and we show how they can be used to compare different segmentation techniques. We use the Simultaneous Truth and Performance Level Estimation (STAPLE) of Warfield et al. but also introduce a novel evaluation technique based on the Willia...

background: physical examination (pe) and breast mri are two of the current methods which have usually used in diagnosis of primary breast cancer. their accuracy in detection of: either complete response or presence of residual tumor, however, has not yet been established in patients who have been received neoadjuvant chemotherapy (nac). the purpose of this study was to evaluate the diagnostic ...
