margin between spots of distinct rows or columns. The width of the margin is equal to 2/�w�, therefore the widest margin is found by minimizing �w� under the constraints ci(w̄ · x̄i − b) ≥ 1, i.e. requiring that all the spots lie on the correct side of the resulting grid line. The support vector machine described above is called a hard-margin SVM and does not take into account any outliers. One o...

Salivary  gland  tumors  accounts  for  less  than  1%  of  all  tumors.  Minor  salivary  gland  tumors (MSGTs) are uncommon and make up about 10% of all salivary gland neoplasms. The clinical and histopathological distribution of these tumors vary geographically. A case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. The tumor invaded into the anterior ...

The longevity of dental restorations is largely dependent on the continuity at the interface between the restorative material and adjacent tooth structure (the restoration margin). Clinical decisions on restoration repair or replacement are usually based upon the weakest point along that margin interface. Physical properties of a restorative material, such as polymerisation shrinkage, water sor...

Retroperitoneal sarcomas are rare tumours that comprise approximately 15% of all soft tissue sarcomas in adults 1 . Most of the retroperitoneal tumours are malignant and approximately one third is soft tissue sarcoma. Although significant advances in our understanding of extremity soft tissue sarcoma have resulted in improved treatments and outcomes, similar progress has not been achieved in ou...

Leiomyosarcoma is a rare form of soft tissue neoplasm, with only 1% to 5% occurring in the head and neck region. Current recommended treatment suggests surgical excision with a wide lateral margin, but no definite guidelines regarding excisional margin have been established yet. Recently, complete excision with a narrow surgical margin has been recommended, and the authors present a case of cut...

Clinical examination revealed an alert child with a tinge of jaundice. An erythematous rash was noted over the anterior abdominal wall. Multiple firm, mobile, discrete and non-tender lymph nodes, about 1 cm in diameter, were palpable in the cervical and inguinal regions. The throat was normal. The liver was enlarged 4 cm below the right costal margin in the mid-clavicular line and was soft and ...

We develop an intuitive geometric framework for support vector regression (SVR). By examining when ǫ-tubes exist, we show that SVR can be regarded as a classification problem in the dual space. Hard and soft ǫ-tubes are constructed by separating the convex or reduced convex hulls respectively of the training data with the response variable shifted up and down by ǫ. A novel SVR model is proposed...
