Medical images are noisy images and its processing is a complex one. The boundary detection of aortas in cardiovascular Magnetic Resonance (MR) images is difficult. This paper presents a vector image and edge map based boundary detection of aortas in cardiovascular MR images and is implemented using MATLAB. The performance of the edge vector and edge map boundary detection method for detecting ...

The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...

We introduce the notion of generalized MR log canonical surfaces and establish minimal model theory for in full generality.

Discrete element modeling is being used increasingly to simulate flow in fluidized beds. These models require complex measurement techniques to provide validation for the approximations inherent in the model. This paper introduces the idea of modeling the experiment to ensure that the validation is accurate. Specifically, a 3D, cylindrical gas-fluidized bed was simulated using a discrete elemen...

Echoes are ubiquitous phenomena in several branches of physics, ranging from acoustics, optics, condensed matter and cold atoms to geophysics. They are at the base of a number of very useful experimental techniques, such as nuclear magnetic resonance, photon echo and time-reversal mirrors. Particularly interesting physical effects are obtained when the echo studies are performed on complex syst...

objective mental retardation (mr) or intellectual disability is one of three chronic and disabling neurological disorders of children and adolescents. its prevalence is estimated 1-3% of the population. mr is defined as significant sub-average intellectual functioning and adaptive behavior that become detectable before the age of 18. mr may come into view before 5 years as delay in at least two...

Introduction: The arterial input function (AIF) plays a crucial role in mapping Cerebral Blood Volume, Mean Transit Time, and Cerebral Blood Flow (CBV, MTT, and CBF) in MR perfusion studies. Automation of the process of selecting an AIF for use in further calculation could substantially reduce bias in hemodynamic parameters introduced by operator dependency and accelerate perfusion analysis. Wh...

11 Myelin is a critical component of the nervous system and a major contributor to contrast in Magnetic Resonance (MR) images. However the precise contribution of myelination to multiple MR modalities is still under debate. The cuprizone mouse is a well established model of demyelination that has been used in several MR studies, but these have often imaged only a single slice and analysed a sma...

The most widely used evolutionary model for phylogenetic trees is the equal-rates Markov (ERM) model. A problem is that the ERM model predicts less imbalance than observed for trees inferred from real data; in fact, the observed imbalance tends to fall between the values predicted by the ERM model and those predicted by the proportional-to-distinguishable-arrangements (PDA) model. Here, a conti...
