Process Optimization of Solution Blow Spinning for Poly (N‐Isopropylacrylamide) Fibers

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Solution blow spinning has emerged as a safe and scalable technique for fabricating thermoresponsive PNIPAM fibers. The influence of key parameters on jet stability and fiber uniformity is determined through both rheological analysis and statistical process optimization. A Box–Behnken design reveals an optimized window for producing PNIPAM fibers below

Matrix Pencil Method Using Fourth-Order Cumulant

, 2020
Introduction In recent years, higher order cumulant-based methods, such as fourth-order cumulant, have received increasing interest due to their advantage over secondorder statistics. The Matrix Pencil method(MPM) can be used when the received signals of

Design of Wiener filters using a cumulant based MSE criterion

, 2010
[[abstract]]© 1996 Elsevier-This paper proposes a cumulant (higher-order statistics) based mean-square-error (MSE) criterion for the design of Wiener filters when both the given wide-sense stationary random signal x(n) and the desired signal d(n) are non-

Safety Assessment of Loop Closing in Active Distribution Networks Based on Probabilistic Power Flow

Energies
To investigate the security issues of loop-closing operations in medium–low-voltage distribution networks under the influence of stochastic fluctuations from distributed generators (DGs) and loads, probabilistic power flow is introduced for analyzing ...

The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Time‐Dependent Single Diffusion Encoding MRI

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Geometric exchange between dendritic spines and shafts is often neglected, yet it exhibits the same signature as permeative exchange, biasing NEXI/SMEX measurements. We propose two models: an extended three‐compartment Kärger model that resolves spine–shaft exchange explicitly, and a coarse‐grained Kärger model that absorbs spines into an effective ...

Market excess returns, variance and the third cumulant [PDF]

, 2015
In this paper, we develop an equilibrium asset pricing model for the market excess return, variance and the third cumulant by using a jump-diffusion process with stochastic variance and jump intensity in Cox, Ingersoll and Ross' (1985) production economy.

A Statistical Perspective on Transformers for Small Longitudinal Cohort Data

Statistics in Medicine, Volume 45, Issue 23-24, October 2026.
ABSTRACT Modeling of longitudinal cohort data typically involves complex temporal dependencies between multiple variables. There, the transformer architecture, which has been highly successful in language and vision applications, allows us to account for the fact that the most recently observed time points in an individual's history may not always be ...

Continuation Method on Cumulant Neglect Equations

, 2018
For stochastic systems, the Fokker–Planck equation (FPE) is used to describe the system dynamics. The FPE is a partial differential equation, which is a function of all the variables in state space and of time. To solve the FPE, several methods are used,

An algorithm for arbitrary–order cumulant tensor calculation in a sliding window of data streams

International Journal of Applied Mathematics and Computer Science, 2019
High-order cumulant tensors carry information about statistics of non-normally distributed multivariate data. In this work we present a new efficient algorithm for calculation of cumulants of arbitrary orders in a sliding window for data streams. We show
