Skew characters and cyclic sieving

open access: yesForum of Mathematics, Sigma, 2021
In 2010, Rhoades proved that promotion on rectangular standard Young tableaux, together with the associated fake-degree polynomial, provides an instance of the cyclic sieving phenomenon.

Mapping mechanical stress in curved epithelia of designed size and shape

open access: yesNature Communications, 2023
The function of organs such as lungs, kidneys and mammary glands relies on the three-dimensional geometry of their epithelium. To adopt shapes such as spheres, tubes and ellipsoids, epithelia generate mechanical stresses that are generally unknown.

Sound radiation by a vortex pair moving near a rectangular cylinder.

open access: yesNihon Kikai Gakkai ronbunshu, 2022
The sound generated by a vortex pair moving close to a rectangular cylinder is studied by high-resolution simulations of the two-dimensional unsteady compressible Navier-Stokes equations at Mach numbers ranging from 0.05 to 0.3.

The effect of added point masses on the geometrically non-linear vibrations of SCSC rectangular plates

open access: yesDiagnostyka, 2022
A point mass added to a plate may have a significant effect on its linear and nonlinear dynamics, including frequencies, mode shapes and the forced response to external loading.

Guiding center picture of magnetoresistance oscillations in rectangular superlattices [PDF]

open access: yes, 2001
We calculate the magneto-resistivities of a two-dimensional electron gas subjected to a lateral superlattice (LSL) of rectangular symmetry within the guiding-center picture, which approximates the classical electron motion as a rapid cyclotron motion ...

Investigating the buckling and vibration of a Kirchhoff rectangular nanoplate using modified couple stress theory

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023
In this paper a model is developed for the buckling and vibration analysis of a Kirchhoff rectangular nanoplate based on a modified couple stress theory.

Tensor Approach to DOA Estimation of Coherent Signals with Electromagnetic Vector-Sensor Array

open access: yesSensors, 2018
This paper addresses the direction-of-arrival (DOA) estimation problem using a uniform rectangular array with electromagnetic vector-sensors in correlated/coherent signal environments. The polarization information is separated from the steering matrix to

Faster Algorithms for Rectangular Matrix Multiplication [PDF]

open access: yes, 2012
Let {\alpha} be the maximal value such that the product of an n x n^{\alpha} matrix by an n^{\alpha} x n matrix can be computed with n^{2+o(1)} arithmetic operations.
