Ky Fan Inequality and Bounds for Differences of Means [PDF]
, 2002 We prove an equivalent relation between Ky Fan-typed inequalities and certain bounds for the differences of means. We also generalize a result of H. Alzer, S.

A collection of seminorms linking the
MathematicsWe investigate a novel operator seminorm, QA,mλ,f, for an A-bounded operator Q, where A is a positive operator on a complex Hilbert space (K,⟨·,·⟩).

Pediatric Blood &Cancer, EarlyView.ABSTRACT We assessed the effect of iron overload (IO) on mortality and complications following hematopoietic stem cell transplantation (HSCT) in patients with Diamond–Blackfan anemia syndrome (DBAS) in a systematic review of individual participant data and cohort data from observational studies.

MSE lower bounds conditioned by the energy detector [PDF]
, 2007 A wide variety of processing incorporates a binary detection test that restricts the set of observations for parameter estimation. This statistical conditioning must be taken into account to compute the Cramer-Rao bound (CRB) and more generally, lower ...

An Improved Bound on (A+A)/(A+A)
The Electronic Journal of Combinatorics, 2016 We show that, for a finite set $A$ of real numbers, the size of the set$$\frac{A+A}{A+A} = \left\{ \frac{a+b}{c+d} : a,b,c,d \in A, c+d \neq 0 \right \}$$is bounded from below by$$\left|\frac{A+A}{A+A} \right| \gg \frac{|A|^{2+1/4}}{|A / A|^{1/8} \log |A|}.$$This improves a result of Roche-Newton (2016).

On bounded functions with bounded 𝑛th differences [PDF]
Proceedings of the American Mathematical Society, 1959 We consider real valued functions f defined in a closed interval I (bounded or unbounded), with nth differences $$ \Delta _{h}^{n}f(x) = \sum\limits_{i} {{{{( - 1)}}^{{n - i}}}} \left( {\begin{array}{*{20}{c}} n \\ i \\ \end{array} } \right)f(x + ih) $$ bounded for some fixed n.

Power bounded and exponentially bounded matrices [PDF]
Applications of Mathematics, 1999 The authors prove spectral decompositions for the power and exponentially bounded matrices and apply these results to obtain series and integral representations of the Drazin inverse and to describe the asymptotic behaviour of solutions of linear ordinary differential equations, including the singular and singularly perturbed ones.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivorship care plans (SCPs) summarize cancer treatment and guide risk‐based follow‐up for cancer survivors, yet remain difficult to create, share, and use. Stakeholder perspectives are needed to inform usable approaches.

Improved sensitivity bounds for mediation under unmeasured mediator–outcome confounding
Journal of Causal InferenceIt is often of interest to decompose a total effect into an indirect effect, relayed through a particular mediator, and a direct effect. However, these effect components are not identified if there are unmeasured confounding of the mediator and the ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
