Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Weighted means and weighting functions

Kybernetika, 2006
Summary: We present some properties of mixture and generalized mixture operators with special stress on their monotonicity. We introduce new sufficient conditions for weighting functions to ensure the monotonicity of the corresponding operators. However, mixture operators, generalized mixture operators neither quasi-arithmetic means weighted by a ...

Psychophysics of the Probability Weighting Function [PDF]

SSRN Electronic Journal, 2011
Abstract A probability weighting function w ( p ) for an objective probability p in decision under risk plays a pivotal role in Kahneman–Tversky prospect theory. Although recent studies in econophysics and neuroeconomics widely utilized probability weighting functions, psychophysical foundations of the probability weighting functions

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

On a Problem Concerning the Weight Functions

European Journal of Combinatorics, 2002
Let \(X\) be a finite set with \(n\) elements. A function \(f: X\to\mathbb{R}\) such that \(\sum_{x\in X} f(x)\geq 0\) is called an \(n\)-weight function. \textit{N. Manickam} and \textit{N. M. Singhi} [J. Comb. Theory, Ser. A 46, 91-103 (1988; Zbl 0645.05023)] conjectured the following: if \(d\) is a positive integer and \(f\) is an \(n\)-weight ...

On a Certain Weighted Partition Function [PDF]

Proceedings of the American Mathematical Society, 1950
Verf. betrachtet von dem in einer früheren Arbeit behandelten Problem [Proc. Am. Math. Soc. 1, 182--191 (1950; Zbl 0037.16903)] den Spezialfall, wo \(\gamma(n)\) die Funktion \(\Lambda(n)\) aus der Primzahltheorie ist. Durch Anwendung der Mellinschen Formel erhält man \[ \log g(s) = -\frac1{2\pi i} \int_{3/2-i\infty}^{3/2+i\infty} \Gamma(z) s^{-z ...

Research on the Improvement of the Signal Time Delay Estimation Method of Acoustic Positioning for Anti-Low Altitude UAVs

Sensors
With the popularity of low-altitude small unmanned aerial vehicles (UAVs), UAVs are often used to take candid photos or even carry out malicious attacks. Acoustic detection can be used to locate UAVs in order to prevent malicious attacks by UAVs.
