Generalized inverse limits of inverse sequences of generalized inverse limits
, 2011 The induced functions between inverse limits of compact metric spaces with upper semicontinuous bonding functions are considered. It is proved that taking such inverse limits is very close to being a functor (but is not a functor) from ICU to CU, if morphisms are mapped to induced functions.

Bordering method to compute Core-EP inverse
Special Matrices, 2018 Following the work of Kentaro Nomakuchi[10] and Manjunatha Prasad et.al., [7] which relate various generalized inverses of a given matrix with suitable bordering,we describe the explicit bordering required to obtain core-EP inverse, core-EP generalized ...

A -partial isometries and generalized inverses
Linear Algebra and its Applications, 2013 Let \(A\) be a positive operator in \(B(H)\). One may consider the semi-inner product \(\langle x,y\rangle_A:=\langle Ax, y\rangle\). An operator \(T\in B(H)\) is called \(A\)-adjointable if it is adjointable with respect to \(\langle \cdot,\cdot\rangle_A\). Clearly, an \(A\)-adjoint \(T^\#\) of \(T\) exists if and only if \(AT^\#=T^*A\). Similarly, by

Generalized inverses of partitioned matrices in Banachiewicz–Schur form
, 2002 The problem of developing conditions under which generalized inverses of a partitioned matrix can be expressed in the so-called Banachiewicz–Schur form is reconsidered. Theorem of Marsaglia and Styan [Sankhyā Ser.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

White Matter Microstructural Abnormalities in Neonatal Onset Genetic Epilepsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Recent evidence indicates that epilepsy is associated with abnormal white matter. If seizures alter white matter, then the impact upon network function, epileptogenesis, and cognition could be pronounced in neonates undergoing rapid developmental myelination. Neonates with epilepsy due to nonstructural genetic causes provide a unique

Generalized inverses of matrices over a finite field
, 1978 For a given m × n matrix A of rank r over a finite field F, the number of generalized inverses, of reflexive generalized inverses, of normalized generalized inverses, and of pseudoinverses of A are determined by elementary methods.

Do all dual matrices have dual Moore–Penrose generalized inverses ?
, 2020 This paper investigates the question of whether all dual matrices have dual Moore-Penrose generalized inverses. It shows that there are uncountably many dual matrices that do not have them.

Associations of Sleep and Shift Work With Osteoarthritis Risk
Arthritis Care &Research, EarlyView.Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift
