methods in this research, we utilized the chaos theory and fractal analysis in the interpretation of breast tumors on dce-mri. this cross-sectional study was done at pardisnoor imaging center during years 2015 and 2016 in iran. our sample size was 18 mass lesions, which were randomly selected among patients with birad 3 and birad 4 classification by the expert radiologist. the analysis was perf...
We present experimental study of vibrofluidized granular materials by high speed photography. Statistical results present the averaged dynamic behaviors of granular materials in one cycle, including the variations of height, velocity and mechanical energy of the center of mass. Furthermore, time-space distribution of granular temperature which corresponds to the random kinetic energy shows that...
Idiopathic granulomatous mastitis is an inflammatory disease with unknown etiology. The clinical signs and mammograms of the disease can mimic breast cancer. The present study reports a case of idiopathic granulomatous mastitis in a pregnant woman. A 26-year-old woman, who was 24 weeks pregnant, felt a mass on her left breast. Biopsy of the mass revealed no evidence of malignancy. For treatment...
We develop the concept of frequency dependent effective mass, M[over ](omega), of jammed granular materials which occupy a rigid cavity to a filling fraction of 48%, the remaining volume being air of normal room condition or controlled humidity. The dominant features of M[over ](omega) provide signatures of the dissipation of acoustic modes, elasticity, and aging effects in the granular medium....
Background & Aim: Breast feeding promotes the child health. World Health Organization recommends breast feeding to be continued till the end of 2 years old, but, sometimes, the process of breastfeeding stops earlier in mothers bearing an excess weight. The mother with excess weight has less successful effort than the others in feeding the babies with their own milk. The aim of this study was ...
A zero-temperature critical point has been invoked to control the anomalous behavior of granular matter as it approaches jamming or mechanical arrest. Criticality manifests itself in an anomalous spectrum of low-frequency normal modes and scaling behavior near the jamming transition. The critical point may explain the peculiar mechanical properties of dissimilar systems such as glasses and gran...
in this study, we offer a general view at the area of fuzzy modeling and fuzzymodels, identify the visible development phases and elaborate on a new and promisingdirections of system modeling by introducing a concept of granular models. granularmodels, especially granular fuzzy models constitute an important generalization of existingfuzzy models and, in contrast to the existing models, generat...
