The Importance of Being Normal
Analysts have used a variety of statistical distributions to model losses due to operational risks [Embrechts, Cruz] or insurance claims [Hogg and Klugman]. In contrast, the normal distribution is the undisputed queen of capital market models. This paper examines an alternative family of distributions, the conic moment family, for application to capital market models. We answer the following qu...
متن کاملFMS-like Tyrosine Kinase-3 Mutation in a Child with Standard-risk ALL and Normal Karyotype
FMS-like tyrosine kinase-3 is a receptor tyrosine kinase expressed by immature hematopoietic cells and is important for the normal development of stem cells and the immune system. Mutations of FMS-like tyrosine kinase-3 have been detected in about 30% of patients with acute myelogenous leukemia and a small number of patients with acute lymphoblastic leukemia. The FMS-like tyrosine kinase-3 muta...
متن کاملNormal human epidermis contains an interferon-like protein
Interferons have been postulated to participate in growth regulation of normal body tissues and are known to inhibit growth of human epidermal keratinocytes in vitro. Polyclonal antibodies to recombinant human interferon-alpha, purified by passage over an affinity column (Sepharose coupled to the recombinant interferon), used in the indirect immunofluorescent method specifically stained the pro...
متن کاملIdentification of androgen receptors in normal human osteoblast-like cells.
The sex steroids, androgens and estrogens, are major regulators of bone metabolism. However, whether these hormones act on bone cells through direct or indirect mechanisms has remained unclear. A nuclear binding assay recently used to demonstrate estrogen receptors in bone [Eriksen, E.F., Colvard, D.S., Berg, N.J., Graham, M.L., Mann, K.G., Spelsberg, T.C. & Riggs, B.L. (1988) Science 241, 84-8...
متن کاملA boundary element analysis of crack-propagation mechanism of micro-cracks in rock-like specimens under a uniform normal tension
In this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. The oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. The present work focuses on the interactions of the pre-existing micro-cracks, which can grow and propagate within a rock-like specimen. The ...
