On a parabolic-hyperbolic Penrose-Fife phase-field system
Electronic Journal of Differential Equations, 2002 The initial and boundary value problem is studied for a non-conserved phase-field system derived from the Penrose-Fife model for the kinetics of phase transitions.

Inference via the Skewness‐Kurtosis Set
International Statistical Review, EarlyView.Summary Kurtosis minus squared skewness is bounded from below by 1, but for unimodal distributions, this parameter is bounded by 189/125. In some applications, it is natural to compare distributions by comparing their kurtosis‐minus‐squared‐skewness parameters. The asymptotic behavior of the empirical version of this parameter is studied here for i.i.d.

A Maximum Principle for a Loaded Hyperbolic-Parabolic Equation
Владикавказский математический журнал, 2016 В работе доказан принцип максимума для нагруженного уравнения гиперболо-параболического типа с переменными коэффициентами. Характеристическая нагрузка представляет собой след искомого решения на линии изменения типа. Полученные результаты обобщают принцип максимума для уравнений гиперболо-параболического типа, приведенный в монографии Т. Д. Джураева, а

The expected inflation risk premium in the U.S. stock market
Journal of Financial Research, EarlyView.Abstract This article studies how expected inflation risk affects asset prices. We propose an ex‐ante, tradable proxy for this risk, derived from the term spread of gold futures prices. Using cross‐sectional and time series asset pricing tests, we show how an increase in expected inflation risk lowers contemporaneous prices and raises equity returns ...

A BOUNDARY VALUE PROBLEM WITH DISPLACEMENT FOR A MODEL EQUATION OF A PARABOLIC-HYPERBOLIC TYPE OF THE THIRD ORDER [PDF]
Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2019 In this paper, a boundary value problem for a model inhomogeneous mixed parabolic-hyperbolic type equation of third order is investigated. A theorem on uniqueness and the existence of a regular solution of the problem under investigation is proved.

Stabilization of some coupled hyperbolic/parabolic equations
Discrete and Continuous Dynamical Systems - B, 2010 First, we consider a coupled system consisting of the wave equation and the heat equation in a bounded domain. The coupling involves an operator parametrized by a real number $\mu$ lying in the interval [0,1].

What in the World Are 4D Shapes?
Noûs, EarlyView.ABSTRACT It is often said that in special relativity, 4D shapes can be used to explain 3D shape projections onto frames of reference. Perdurantists have frequently used this as a motivation for their view of persistence. Despite this, philosophers never clearly state what 4D shapes are.

Mathematics, 2020 A type of Hyers–Ulam stability of the one-dimensional, time independent Schrödinger equation was recently investigated; the relevant system had a parabolic potential wall.

Plant Biology, EarlyView.In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.
