introduction: orofacial clefts are among the most common congenital anomalies. patients presenting with orofacial clefts often require surgery or other complex procedures. a cleft lip or palate can be a single anomaly or a part of multiple congenital anomalies. the reported prevalence of cleft disease and associated anomalies varies widely across the literature, and is dependent on the diagnost...

The purpose of this article is to introduce a new scheme for robust multivariate ranking by making use of a not so familiar notion called monotonicity. Under this scheme, as in the case of classical outward ranking, we get an increasing sequence of regions diverging away from a central region (may be a single point) as nucleus. The nuclear region may be deened as the median region.

EDITOR—The CHARGE association is an increasingly recognised pattern of congenital anomalies comprising colobomata, heart defects, choanal atresia, retarded growth and development, hypoplastic genitalia, and ear abnormalities/deafness. We report a case of CHARGE association with a de novo chromosomal aberration, 46,X,+der(X)t(X;2), which was detected by spectral karyotyping. The proband, an 11 y...

hyperion hyperspectral data contains a very rich source of information from the earth surface that collects 242 narrow contiguous spectral bands. achieving this source of rich information is subject to the performance of suitable image processing methods on raw satellite data. satellite image processing methods can be classified into two categories of statistical-based and spectral-based. in th...

We study spectral triples on (weighted) groups and consider functors between the categories of weighted groups and spectral triples. We study the properties of weights and the corresponding functor for spectral triples coming from discrete weighted groups.

In this lecture, we discuss some spectral techniques and their applications. The goal of spectral techniques is to study and deduce the characteristics of a matrix by looking at its spectrum (i.e. eigenvalues of matrix). Although spectral methods can be applied to any problem instance with matrix representation, we will be focussing on graph theoretic problems in this lecture. Over the past two...

one of the main goals of interpretation of gravity data is to detect location and edges of the anomalies. edge detection of gravity anomalies is carried out by different methods. terracing of the data is one of the approaches that help the interpreter to achieve appropriate results of edge detection. this goal becomes a complex task when the gravity anomalies have smooth borders due to gradual ...
