We investigated the predictive power of morphological features in 224 autistic patients and 224 matched-pairs controls. To assess the relationship between the morphological features and autism, we used the receiver operator curves (ROC). In addition, we used recursive partitioning (RP) to determine a specific pattern of abnormalities that is characteristic for the difference between autistic ch...

The main objective of this research is to develop a methodology for identifying different varieties of paddy seeds using morphological features. Morphological features are powerful tool which could separate the different varieties of seeds. Three varieties of paddy seeds are taken that are classified according to their morphological feature range. Image of paddy seeds was acquired by a canon di...

This paper compares the performance of four statistical classifiers, namely linear discriminant classifier, quadratic discriminant classifier, k-Nearest Neighborhood classifier, and parzen classifier are considered for recognition of 2D-shapes. The two features from morphological skeletons and four features from morphological shape decomposition are identified from 2D-shapes. These features are...

This study was designed to examine morphological features in a large group of children with autism spectrum disorder versus normal controls. Amongst 421 patients and 1,007 controls, 224 matched pairs were created. Prevalence rates and odds ratios were analyzed by conditional regression analysis, McNemar test or paired t-test matched pairs. Morphological abnormalities were significantly more pre...

We report our current effort on extracting morphological features from neuronal dendrite patterns using the eigenvalues of their graph Laplacians and clustering neurons using those features into different functional cell types. Our preliminary results indicate the potential usefulness of such eigenvalue-based features, which we hope to replace the morphological features extracted by methods tha...

Acute promyelocytic leukemia (APL) has two morphological variants, namely macrogranular (M3) and microgranular (M3v). M3v, characterized by the presence of neoplastic promyelocytes with only sparse fine azurophilic granules, accounts for 10-25% of all APL and has unique biological characteristics. Relapse occurs in approximately 20% of patients with APL. The morphological type of the leukemic c...

Understanding the processes involved in evolution of organisms is a principal topic that has received much attention from the research community. A common way to achieve this is to study the ecological conditions and morphological relationships of taxa. Fish are widely regarded as notable animal models in studies of environmental influence on morphological features given their high environmenta...

dendritic cells function as the main cellular population responsible for professional antigen presentation and hence for induction of primary immune responses. although they are present in virtually every tissue, nevertheless their number is usually so low that it makes their isolation for studies very difficult. in this study, we purified dendritic cells from mouse spleen by a three-step enric...
