Note on Hermitian Jacobi Forms
We compare the spaces of Hermitian Jacobi forms (HJF) of weight and
indices with classical Jacobi forms (JF) of weight and indices
. Using the embedding into JF, upper bounds for the order of vanishing
of HJF at the origin is obtained. We compute the rank of HJF as a module over
elliptic modular forms and prove the algebraic independence of the generators
in case of index 1. Some related questions are discussed.Comment: 24 pages; title changed, abstract changed, some proofs expanded and

Simultaneous nonvanishing of Dirichlet -functions and twists of Hecke-Maass L-functions
We prove that given a Hecke-Maass form for and
a sufficiently large prime , there exists a primitive Dirichlet character
of conductor such that the -values and do not vanish. We expect the same method to
work for any large integer
Linear Relations Among Poincare Series via Harmonic Weak Maass Forms
We discuss the problem of the vanishing of Poincar\'e series. This problem is
known to be related to the existence of weakly holomorphic forms with
prescribed principal part. The obstruction to the existence is related to the
pseudomodularity of Ramanujan's mock theta functions. We embed the space of
weakly holomorphic modular forms into the larger space of harmonic weak Maass
forms. From this perspective we discuss the linear relations between Poincar\'e
series and the connection to Ramanujan's mock theta functions
Hemolytic Disease of the Fetus and Newborn
Hemolytic disease of the fetus and newborn (HDFN) also called as “erythroblastosis fetalis” is characterized by the increased rate of red blood cells (RBCs) destruction. Hemolysis should always be investigated even if the anemia is mild and apparently trivial. The principle clues which suggest hemolytic anemia includes: increased number of reticulocytes and/or circulating nucleated RBCs, unconjugated hyperbilirubinemia, a positive direct antiglobulin test and characteristic changes in red cells in the blood films. Based on etiology, hemolysis in newborn can be immune or non-immune mediated. The immune-mediated hemolysis due to blood group incompatibility between the mother and the fetus is the main cause of HDFN
