A Blockwise Bootstrap-Based Two-Sample Test for High-Dimensional Time Series

Entropy
We propose a two-sample testing procedure for high-dimensional time series. To obtain the asymptotic distribution of our ℓ∞-type test statistic under the null hypothesis, we establish high-dimensional central limit theorems (HCLTs) for an α-mixing ...

Semantic Segmentation of Maxillary Teeth and Palatal Rugae in Two-Dimensional Images

Diagnostics, 2022
The superimposition of sequential radiographs of the head is commonly used to determine the amount and direction of orthodontic tooth movement. A harmless method includes the timely unlimited superimposition on the relatively stable palatal rugae, but the method is performed manually and, if automated, relies on the best fit of surfaces, not only rugal

Two-dimensional truth

Studia Philosophica Estonica, 2008
The paper identifies two major strands of truth theories, ontological and epistemological ones, and argues that both are of equal primacy and find their home within two-dimensional semantics.

Line Defects in Quasicrystals

Crystals
The six-dimensional framework of the integral formalism for line defects (straight dislocations and line forces) in anisotropic elasticity has been extended to a 2n-dimensional integral formalism for line defects in quasicrystals (n=4,5,6 for one-, two-,

Reconciling Chord Length Distributions and Area Distributions for Fields of Fractal Cumulus Clouds

Atmosphere, 2020
While the total cover of broken cloud fields can in principle be obtained from one-dimensional measurements, the cloud size distribution normally differs between two-dimensional (area) and one-dimensional retrieval (chord length) methods.

Noncommutative Reduction of Nonlinear Schrödinger Equation on Lie Groups

Universe, 2022
We propose a new approach that allows one to reduce nonlinear equations on Lie groups to equations with a fewer number of independent variables for finding particular solutions of the nonlinear equations.

Two Propositions for Total Semantics [PDF]

, 2019
The history of two-dimensional semantics emanates from historical issues surrounding Kripke’s notion of rigidity. In this paper, I recreate the debate between Kripke, Dummett and Evans to arrive at early formulations of two-dimensional semantics by Lewis,

Finite Integration Method with Chebyshev Expansion for Shallow Water Equations over Variable Topography

Mathematics
The shallow water equations (SWEs) model fluid flow in rivers, coasts, and tsunamis. Their nonlinearity challenges analytical solutions. We present a numerical algorithm combining the finite integration method with Chebyshev polynomial expansion (FIM-CPE)

Matrices and Modalities: On the Logic of Two-Dimensional Semantics [PDF]

, 2011
Two-dimensional semantics is a theory in the philosophy of language that provides an account of meaning which is sensitive to the distinction between necessity and apriority. Usually, this theory is presented in an informal manner.
