The relevance of 8 contemporary classification and grading systems for ductal carcinoma in situ (DCIS) of the breast was examined in 100 tumors by comparing DCIS grade with grade of the concurrent infiltrating ductal carcinoma (IDC). Besides tumor size and nodal status, the immunohistochemical parameters in both lesions were compared, including estrogen receptor, progesterone receptor, c-erbB-2...

Fluidized beds are widely used in industrial operations due to their ability to give good mixing and a high contact area between the phases. The excellent controlling ability of temperature allows good operating conditions for solid catalyzed gas phase reactions and also the ease of the design. Powders used in industrial ‡uidized beds have a particle size distribution, and the particle size dis...

Glioma is the most occurring brain tumor in world. Its grade (level of severity) identification, crucial its treatment planning, demanding a clinical environment. Computer-aided methods have been experimented with to identify glioma, out which deep learning-based methods, due their auto features engineering, good impact terms achieved outcomes. In this study, convolutional neural networks (CNNs...

OBJECTIVES We proposed that the severity of ST-segment elevation myocardial infarction (STEMI) could be classified based on pathophysiological changes. METHODS First-STEMI patients were classified within hospitalization. Grade 0: no detectable myocardial necrosis; Grade 1: myocardial necrosis without functional and morphological abnormalities; Grade 2: myocardial necrosis with reduced LVEF; G...

one studies the $hx$-hypergroups, corresponding to the chinese hypergroups associated with the direct products of some ${bf z}/n {bf z},$ calculating their fuzzy grades.

in this study we have described our varicocele cases in terms of associated symptoms/signs. in addition, we have tested the correlation between semen parameters and varicocele grades and compared the relative frequencies of associated symptoms/signs in different varicocele grades. 1 19 referred cases of varicocele were categorized based on clinical criteria into 3 grades by one examiner. the re...

The mine production planning defines a sequence of block extraction to obtain the highest NPV under a number of constraints. Mathematical programming has become a widespread approach to optimize production planning, for open pit mines since the 1960s. However, the previous and existing models are found to be limited in their ability to explicitly incorporate the ore grade uncertainty into the p...

in this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in esr processing has been investigated.the chemical composition and microstructure studies were evaluated, using spectrophotometer,omand edx analyses attached to sem.the results show that esr process has successfully reduced the amount and size of inclusions. in some c...

PURPOSE The purpose of this study was to establish criteria for the indication of sublobar resection or lobectomy in cT1N0M0 non-small cell lung cancer (NSCLC), based on information from both computed tomography (CT) and fluorodeoxyglucose positron emission tomography (FDG PET). MATERIALS AND METHODS A total of 248 cT1N0M0 NSCLC tumors treated surgically were subjected to high-resolution or t...
