The definition of the concept of “learning object” is still subject to considerable debate and controversy, causing some degree of confusion and ambiguity in research about the topic. Proposed definitions differ in terms of broadness of scope, focus on reusability and requirements imposed on metadata, among other characteristics. Nonetheless, if we approach the definition from the narrower pers...

Many aerial images with similar appearances have different but correlated scene labels, which causes the label ambiguity. Label distribution learning (LDL) can express ambiguity by giving each sample a distribution. Thus, contributes to of its ground-truth as well improve data utilization. LDL has gained success in many fields, such age estimation, be easily modeled on basis prior knowledge abo...

A type confusion attack is one in which a principal accepts data of one type as data of another. Although it has been shown by Heather et al. that there are simple formatting conventions that will guarantee that protocols are free from simple type confusions in which fields of one type are substituted for fields of another, it is not clear how well they defend against more complex attacks, or a...

Formulating SQL queries involving joins is tedious, error-prone, and requires in-depth schema knowledge. We demonstrate a modified version of SQL [2] that does not require specification of table references and joins. The Schema-Free SQL system can expresses queries not supported in keyword-based searches [1]. Unlike Universal Relation approaches, the system is scaleable to large schemas, and it...

Ambiguity is the quality of being open to several interpretations. For an image, it arises when the contained elements can be delimited in two or more distinct ways, which may cause confusion. We postulate that it also applies to the analysis of protein three-dimensional structure, which consists in dividing the molecule into subunits called domains. Because different definitions of what consti...

Congenital adrenal hyperplasia is a group of inherited disorders caused by an enzyme deficiency in steroid biosynthesis. The most common form of congenital adrenal hyperplasia is 21-hydroxylase deficiency, which in its severe form can cause genital ambiguity in females. Steroid 21-hydroxylase deficiency can be diagnosed in utero through molecular genetic analysis of fetal DNA. Prenatal treatmen...
