An axial four-index transportation problem and its algebraic characterizations

Autor: Hamza Bulut, S. Aysun Bulut

Publikováno v: International Journal of Computer Mathematics. 81:765-773

In this study, we describe an axial four-index transportation problem of order 1 x m x n x 1, which is equivalent to a circularization network flow problem with m + n + 2 nodes and ( m + 1)( n + 1) arcs. We then give some algebraic characterizations

Publikováno v: Neurology. 59:1783-1786

Most cases of dopa-responsive dystonia (DRD) are thought to be caused by mutations in the GCHI gene; however, by sequencing, mutations are found in only 40% to 60%. Recently, a single report identified, via Southern blot analysis, a large genomic GCH

Construction and Algebraic Characterizations of the Planar and Axial Transportation Problems

Autor: S. Aysun Bulut

Publikováno v: Journal of Mathematical Analysis and Applications. 220(2):535-552

We describe the construction and several algebraic characterizations of the planar and axial transportation problems using the generalized inverse and the singular value decomposition of their coefficient matrices, and investigate relations between t

Reproductive decisions after prenatal diagnosis in neurofibromatosis type 1: importance of genetic counseling

Autor: Y K, Terzi, S, Oguzkan-Balci, B, Anlar, S, Aysun, S, Guran, S, Ayter

Publikováno v: Genetic counseling (Geneva, Switzerland). 20(2)

Neurofibromatosis type 1 (NF1) is one of the most common autosomal dominant disorders affecting approximately 1/3500 individuals in all ethnic groups. It is characterized by cutaneous and plexiform neurofibromas, café-au-lait spots, Lisch nodules, f
