Characteristic polynomials of complex random matrix models
We calculate the expectation value of an arbitrary product of characteristic polynomials of complex random matrices and their hermitian conjugates. Using the technique of orthogonal polynomials in the complex plane our result can be written in terms of

The integral representations of the solution manifold for one class of the first order model integro-differential equation with logarithmic singularity in the kernel are constructed using arbitrary constants. The cases when the given integro-differential

Analysis of a characteristic equation
The authors investigate a characteristic equation occurring in epidemic models formulated in terms of integro-differential equations, where births and deaths are introduced and the total population size is assumed to be constant. They establish conditions on the two parameters of this equation, under which an equilibrium position is stable.

The Relationship Between Semiclassical Laguerre Polynomials and the Fourth Painlevé Equation [PDF]
We discuss the relationship between the recurrence coefficients of orthogonal polynomials with respect to a semiclassical Laguerre weight and classical solutions of the fourth Painlevé equation. We show that the coefficients in these recurrence relations

Partial Prolongations and Characteristics of Differential Equations [PDF]
This paper studies the behavior of characteristics under partial prolongations. Partial prolongations define a natural equivalence relation between systems of partial differential equations [2], [3]. Examples are given to show that characteristics are not preserved in general.

ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.
