The Filament Extension Atomization Process for Powder Production of Elastic Fluids
Chemie Ingenieur Technik, EarlyView.Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.

Eigenvalue Asymptotics of the Even-Dimensional Exterior Landau-Neumann Hamiltonian
Advances in Mathematical Physics, 2009 We study the Schrödinger operator with a constant magnetic field in the exterior of a compact domain in ℝ2𝑑, 𝑑≥1. The spectrum of this operator consists of clusters of eigenvalues around the Landau levels.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

On the spectrum of the negative Laplacian for general doubly-connected bounded domains
International Journal of Mathematics and Mathematical Sciences, 1995 This paper is devoted to asymptotic formulas for functions related with the spectrum of the standard Laplace operator in two and three dimensional bounded doubly connected domains with impedance boundary conditions, where the impedances are assumed to be

An Asymptotic Formula for Binomial Sums
Journal of Number Theory, 1996 This paper studies asymptotic expansions for binomial sums of the form \[ S(n)=\sum^n_{k=0}\begin{pmatrix} n\\ k\end{pmatrix}^{r_0}\begin{pmatrix} n+k\\ k\end{pmatrix}^{r_1}\begin{pmatrix} n+2k\\ k\end{pmatrix}^{r_2}\dots\begin{pmatrix} n+mk\\ k\end{pmatrix}^{r_m}, \] where the \(r_j\) are nonnegative real numbers with \(r_0>0\). The main result is the

Restricted Tweedie stochastic block models
Canadian Journal of Statistics, EarlyView.Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Subuniformity of harmonic mean p$$ p $$‐values
Canadian Journal of Statistics, EarlyView.Abstract We obtain several inequalities on the generalized means of dependent p$$ p $$‐values. In particular, the weighted harmonic mean of p$$ p $$‐values is strictly subuniform under several dependence assumptions of p$$ p $$‐values, including independence, negative upper orthant dependence, the class of extremal mixture copulas, and some Clayton ...
