A Binary-Based Matrix Model for Malus Corolla Symmetry and Its Variational Significance [PDF]

open access: yesFrontiers in Plant Science, 2020
Floral symmetry (corolla symmetry) has important biological significance in plant genetics and evolution. However, it is often multi-dimensional and difficult to quantify.

Modeling Pine Caterpillar, Dendrolimus spectabilis (Lepidoptera: Lasiocampidae), Population Dynamics with a Stage-Structured Matrix Model Based on Field Observations [PDF]

open access: yesInsects
Population models offer insights into both theoretical and practical aspects of insect population dynamics. Among the models, stage-structured matrix models are used to describe the population dynamics of insects because the development of insects is by ...

Analysis and Simulation of Shielding Effectiveness of a Fiber Reinforced Cylindrical Shell

open access: yesMehmet Akif Ersoy Üniversitesi Fen Bilimleri Enstitüsü, 2021
The purpose of the paper is to analyze and simulate the shielding effectiveness (SE) performance of a fiber reinforced cylindrical shell. A matrix model is presented to evaluate the transmitted electromagnetic fields on the axis of cylindrical shell.

Celestial Matrix Model

open access: yesPhysical Review Letters, 2022
We construct a Hermitian random matrix model that provides a stable non-perturbative completion of Cangemi-Jackiw (CJ) gravity, a two-dimensional theory of flat spacetimes. The matrix model reproduces, to all orders in the topological expansion, the Euclidean partition function of CJ gravity with an arbitrary number of boundaries.

Impacts of run‐of‐river hydropower on coho salmon (Oncorhynchus kisutch): the role of density‐dependent survival

open access: yesEcosphere, 2021
Predicting whether anthropogenic sources of mortality have negative consequences at the level of population dynamics is challenged by mechanisms like density‐dependent survival that can amplify or offset the loss of individuals from anthropogenic ...

A Matrix Model for Creating Logical Filters of an Electronic Catalog of Prosthetic Modules for Customized Prostheses

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2022
Introduction. When synthesizing a prosthesis from ready-made prosthesis units, the prosthetist is faced with the problem of selecting from a large range of components that differ in properties and characteristics.

Renormalization Group Approach to the Continuum Limit of Matrix Models of Quantum Gravity With Preferred Foliation

open access: yesFrontiers in Physics, 2021
This contribution is not intended as a review but, by suggestion of the editors, as a glimpse ahead into the realm of dually weighted tensor models for quantum gravity.

The Anderson Model as a matrix model [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
In this paper we describe a strategy to study the Anderson model of an electron in a random potential at weak coupling by a renormalization group analysis. There is an interesting technical analogy between this problem and the theory of random matrices.
