onion is one of the important strategic crop plants of a highly valuable nutritional food source, consumed almost around the whole world. thus, the genetically oriented studies around the plant are valuable and inevitable. for a following of these studies, some onion masses from various regions throughout iran, including: kashan-white, azarshahr-red, isfahan-dorcheh, ghom-white, zanjan-gholighe...

When the available statistical information is imperfect, it is dangerous to follow standard optimisation procedures to construct an optimal portfolio, which usually leads to a strong concentration of the weights on very few assets. We propose a new way, based on gener-alised entropies, to ensure a minimal degree of diversiication.

In this paper, we implement and carry out the comparison of two methods of computer-aided-detection of masses on mammograms. The two algorithms basically consist of 3 steps each: segmentation, binarization and noise suppression using different techniques for each step. A database of 60 images was used to compare the performance of the two algorithms in terms of general detection efficiency, con...

Patients with mediastinal masses present unique challenge to anesthesiologists. Patients with anterior mediastinal masses have well documented cases of respiratory or cardiovascular collapse during anesthesia and in postoperative period. Masses in the posterior mediastinum have been traditionally regarded to carry a significantly lower risk of anesthesia related complications but cases of near ...

We carry out an analysis of the non-universal supersymmetry breaking scalar masses arising in SO(10) supersymmetric unification. By considering patterns of squark and slepton masses, we derive a set of sum rules for the sfermion masses which are independent of the manner in which SO(10) breaks to the Standard Model gauge group via its SU(5) subgroups. The phenomenology arising from such non-uni...

The importance of the mass spectroscopy of the superparticles is emphasized. It will be shown that the gauge coupling constants give us information on the GUT-scale mass spectrum once the superparticle masses are known. The gaugino masses will provide us a model-independent test of the grand unification irrespective of the symmetry breaking pattern. The sfermion masses carry the information on ...

The probabilistic Noisy OR model has been widely used as a means of reducing the amount of probabilistic information that is needed to specify the interaction between groups of variables. Motivated by our work on the diagnosis of faults in satellite subsystems , which required a similar synthesis of partial possibilistic information on interactions , we consider a number of ways of gener-alisin...

Background: Thyroid masses are common, especially in areas of iodine deficiency. Mediastinal goiter is defined by the presence of enlarged thyroid tissue below the level of the thoracic inlet. This study aimed to evaluate the presentation, diagnosis, treatment, histopathological findings and complications of patients with mediastinal goiter or masses. Materials and Methods: This was a descripti...
