Vertical Price Transmission in Food Markets: New Evidence From Meta‐Analysis

open access: yesAgribusiness, EarlyView.
ABSTRACT A growing body of empirical research has examined price dynamics along the food supply chain, yet findings remain heterogeneous and often conflicting. This study conducts a meta‐analysis of 140 studies, totaling 652 observations, to examine (1) the reported presence of asymmetric price transmission and (2) the reported direction of price ...

Partial Derivative Equations and Identities for Hermite-Based Peters-Type Simsek Polynomials and Their Applications

open access: yesMathematics
The objective of this paper is to investigate Hermite-based Peters-type Simsek polynomials with generating functions. By using generating function methods, we determine some of the properties of these polynomials.

Biquadratic Transformations for Checking the Hurwitz Stability via the Schur Stability

open access: yesAsian Journal of Control, EarlyView.
ABSTRACT Bilinear transformations such as the Möbius transformation have been used to study Hurwitz stability by means of Schur stability, or vice versa. However, the use of a well‐known Möbius transformation has pathological cases, hence Jalili–Kharaajoo and Araabi investigated and found a biquadratic transformation to study Schur stability by means ...

Finding identities and q-difference equations for new classes of bivariate q-matrix polynomials

open access: yesApplied Mathematics in Science and Engineering
This article introduces 2-variable q-Hermite matrix polynomials and delves into their complex representation, unravelling specific outcomes. The exploration encompasses the derivation of insightful identities for the q-cosine and q-sine analogues of the ...

Extension of Stein’s lemma derived by using an integration by differentiation technique

open access: yesExamples and Counterexamples, 2022
We extend Stein’s lemma for averages that explicitly contain the Gaussian random variable at a power. We present two proofs for this extension of Stein’s lemma, with the first being a rigorous proof by mathematical induction.

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

On the hermite matrix of a polynomial

open access: yesLinear Algebra and its Applications, 1971
AbstractWe investigate the location of the eigenvalues of the Hermite matrix of a given complex polynomial, the question under what conditions a given polynomial and the characteristic polynomial of its Hermite matrix are identical, and the question under what conditions the Hermite matrix has only one distinct eigenvalue.

Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...

Three‐Dimensional Optical Characterization of Magnetostrictive Deformation in Magnomechanical Systems

open access: yesLaser &Photonics Reviews, EarlyView.
An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.
