Among Medical products, jujube (Ziziphus jujuba Mill.) is very important due to its very high nutritional value. Jujube as one of the most valuable medicinal plants can play an important role in Iran's non-oil exports. In spite of this fact, unfortunately, the production, distribution and marketing of this product are confronted with a number of obstacles. Therefore, this study can help for ide...

Standard contrastive learning approaches usually require a large number of negatives for effective unsupervised and often exhibit slow convergence. We suspect this behavior is due to the suboptimal selection used offering contrast positives. counter difficulty by taking inspiration from support vector machines (SVMs) present max-margin (MMCL). Our approach selects as sparse vectors obtained via...

The tremendous recent success of deep neural networks (DNNs) has sparked a surge interest in understanding their predictive ability. Unlike the human visual system which is able to generalize robustly and learn with little supervision, DNNs normally require massive amount data new concepts. In addition, research works also show that are vulnerable adversarial examples-maliciously generated imag...

Discrepancy in the labial gingival margin of the maxillary incisors poses a major aesthetic problem. Orthodontic extrusion can improve the aesthetic problem caused by gingival margin levels before restoration. In these case reports, orthodontic extrusion was performed with palatal circumferential supracrestal fiberotomy for improving the discrepancy of the labial gingival margin. Two years post...

AIM There is debate as to what constitutes an adequate excision margin to reduce the risk of locoregional recurrence (LRR) after breast cancer surgery. We have investigated the relationship between surgical margin distance and LRR in women with invasive breast cancer (IBC). METHODS Tumour free margin distances were extracted from histopathology reports for women with IBC, treated by either br...
