Congenital leukemia is a rare disease which in clinically evident at birth or apparent within the first few weeks of life; The disease is more common in infants with downs syndrome.  We present a case of combined mongolism and congenital leukemia and reviewe some aspect of the disease. 

§ 1. Introduction We shall mainly deal with linear recursion formulas of the type n-1 (l. 1) f(1) = 1 ; /(n) _ i~ ck f(n-k) (n = 2, 3,. . .), k=1 and with quadratic formulas of the type n-1 (1. 2) f(1) = 1 ; /(n) _ d, f(k)/(n-k) (n = 2,3. . .). k=1 We assume that ck > 0, d k > 0 (k = 1, 2,. . .). In a previous paper [1] we discussed (1. 1) under the condition X° ck = 1, and further special assu...

Many successful attempts have been made to deduce information from data. Such data might come from an explicit body of knowledge, for example from a data base. Alternatively the data might be implicit, for example the behaviour of a system. The system may itself be physical such as a helicopter or a factory, or it may be conceptual such as a financial system. The extraction of information from ...

The purpose of this talk is to give an overview of the status of some problems in approximability.

Various liposomal drug carriers have been developed to overcome short plasma half-life and toxicity related side effects of chemotherapeutic agents. We developed a mathematical model to compare different liposome formulations of doxorubicin (DOX): conventional chemotherapy (Free-DOX), Stealth liposomes (Stealth-DOX), temperature sensitive liposomes (TSL) with intra-vascular triggered release (T...

Stealth assessment represents a promising way to address the needs of validly measuring and supporting important 21st century competencies (e.g., creativity, problem solving) within interactive digital environments (e.g., video games). The assessment is woven into the environment such that it becomes invisible to students, which is conducive to eliciting targeted competencies (Shute, 2011). Ste...
