on the basis of acreage, production and import amounts, maize is one of the strategic products in iran, regarding defects of marketing system of maize, in this analysis using yearly observations between 1368 to 1385 (18 years) and eviews software, the marketing and econometric model of maize marketing margin was studied. the results show that the most important factor in the maize marketing mar...

Surgical margin status at prostatectomy is an important predictor of biochemical recurrence (BCR). The current convention is to categorize a margin as negative if tumor cells are not at the inked margin, even if they are within a few cells of the margin. We hypothesized that cancer within 0.1 mm of the margin conferred an increased risk for BCR. We determined the risk for BCR on the bass of sur...

Background—Various factors aVect gastric wound healing. The influence of physical stimulation on gastric mucosal cells during the process of gastric wound healing is not completely understood. Aims—To assess the role of a physical stimulant, in this case mechanical strain, on gastric mucosal restoration. Methods—Mechanical strain was applied to adherent rat gastric mucosal cells (RGM1) cultured...

We present a maximum margin framework that clusters data using latent variables. Using latent representations enables our framework to model unobserved information embedded in the data. We implement our idea by large margin learning, and develop an alternating descent algorithm to effectively solve the resultant non-convex optimization problem. We instantiate our latent maximum margin clusterin...

In the treatment of cancer the fundamental surgical goal is to remove all local malignant disease and leave no residual malignant cells. Studies have demonstrated the benefit of achieving negative resection margins in terms of disease free local recurrence and overall survival. The surgical margins for Head & Neck cancer may vary widely depending on the site of disease. This variation reflects ...

Most object detection methods operate by applying a binary classifier to sub-windows of an image, followed by a non-maximum suppression step where detections on overlapping sub-windows are removed. Since the number of possible sub-windows in even moderately sized image datasets is extremely large, the classifier is typically learned from only a subset of the windows. This avoids the computation...

Margin maximizing properties play an important role in the analysis of classi£cation models, such as boosting and support vector machines. Margin maximization is theoretically interesting because it facilitates generalization error analysis, and practically interesting because it presents a clear geometric interpretation of the models being built. We formulate and prove a suf£cient condition fo...
