Rank Function and Outer Inverses

The Electronic Journal of Linear Algebra, 2018
For the class of matrices over a field, the notion of `rank of a matrix' as defined by `the dimension of subspace generated by columns of that matrix' is folklore and cannot be generalized to the class of matrices over an arbitrary commutative ring. The `determinantal rank' defined by the size of largest submatrix having nonzero determinant, which is ...

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Ranks on the Baire class $\xi $ functions [PDF]

Transactions of the American Mathematical Society, 2016
In 1990 Kechris and Louveau developed the theory of three very natural ranks on the Baire class $1$ functions. A rank is a function assigning countable ordinals to certain objects, typically measuring their complexity. We extend this theory to the case of Baire class $ξ$ functions, and generalize most of the results from the Baire class 1 case. We also

Rank functions of closure spaces of finite rank

Discrete Mathematics, 1984
A closure space \((S,)\) consists of a set S together with a closure operator \(\). In such a space, the set X is closed if \(=X\) while the rank \(\rho\) (A) of a closed set A is the maximum length r of a chain of closed sets \(A_ i\) such that \(A_ 0\varsubsetneq A_ 1\varsubsetneq...\varsubsetneq A_ r=A\) where, if this maximum does not exist, \(\rho\

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Cancer module genes ranking using kernelized score functions

BMC Bioinformatics, 2012
Background Co-expression based Cancer Modules (CMs) are sets of genes that act in concert to carry out specific functions in different cancer types, and are constructed by exploiting gene expression profiles related to specific clinical conditions or ...
