Approximation Error Bounds via Rademacher's Complexity [PDF]
, 2008 Approximation properties of some connectionistic models, commonly used to construct approximation schemes for optimization problems with multivariable functions as admissible solutions, are investigated.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Instruction Tenapanor potentially affects fluid volume and blood pressure. This study explored its effects on these parameters in patients undergoing peritoneal dialysis (PD). Methods We conducted a single‐arm, prospective observational study that enrolled 10 patients on PD with hyperphosphatemia who were newly initiated on tenapanor.

Trigonometric approximation by Nörlund type means in $L^p$-norm [PDF]
, 2002 summary:We show that the same degree of approximation as in the theorems proved by L. Leindler [Trigonometric approximation in $L^p$-norm, J. Math. Anal. Appl. 302 (2005), 129--136] and P.

On the lower semi-continuity of the set valued metric projection
International Journal of Mathematics and Mathematical Sciences, 1992 The lower semi-continuity of best approximation operators from Banach lattices on to closed ideals is investigated. Also the existence of best approximation to sub-function modules of function modules is proved. The order intersection properties of cells

A Lower Bound for Approximating Grundy Numbering.
Discret. Math. Theor. Comput. Sci., 2007 The grundy numbering of a graph is the maximum number of colors used by on-line first-fit coloring, under the worst order of arrival of vertices. The grundy numbering problem is to find this ordering. We prove that there is a constant c>1 so that approximating the grundy numbering problem within c is not possible, unless NP ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

A Tight 4/3 Approximation for Capacitated Vehicle Routing in Trees [PDF]
, 2018 Given a set of clients with demands, the Capacitated Vehicle Routing problem is to find a set of tours that collectively cover all client demand, such that the capacity of each vehicle is not exceeded and such that the sum of the tour lengths is ...

A lower bound in asymptotic diophantine approximations
Duke Mathematical Journal, 1968 Let \(\alpha\) be a real irrational number. Define for all real numbers \(B\ge 1\), \(\lambda(B,\alpha)\) to be the number of solutions in integers \(q\), \(p\) of the inequalities \(\vert q\alpha - p\vert < 1/q\), \(1\le q\le B\). It is known [\textit{W. Schmidt}, Can. J. Math.
