Recognition of small numbers in subset knowers Cardinal knowledge in early childhood
Royal Society Open Science, 2023 Previous research suggests that subset-knowers have an approximate understanding of small numbers. However, it is still unclear exactly what subset-knowers understand about small numbers.

Optical Code Construction of 2D Spectral/Spatial BIBD Codes for SAC-OCDMA Systems
Applied Sciences, 2021 Optical code division multiple access (OCDMA) shows limitations in terms of the inefficient bandwidth utilization and low spectral density with one-dimensional (1D) codes. To overcome these limitations, a novel design is presented using a two dimensional

Encoding High-Cardinality String Categorical Variables [PDF]
IEEE Transactions on Knowledge and Data Engineering, 2019 Statistical models usually require vector representations of categorical variables, using for instance one-hot encoding. This strategy breaks down when the number of categories grows, as it creates high-dimensional feature vectors.

Journal of Mathematics Education at Teachers College, 2019 High school students often ask questions about the nature of infinity. When contemplating what the “largest number” is, or discussing the speed of light, students bring their own ideas about infinity and asymptotes into the conversation.

Proof of cantor’s continuum hypothesis [PDF]
Journal of Hyperstructures, 2012 We shall attempt to prove Cantor’s General Continuum Hypothesis, a special case of which is known as the Continuum Hypothesis, namely that the cardinality of the power set of an infinite set is the consecutive cardinality. An ordered field of cardinality

Computable Diagonalizations and Turing’s Cardinality Paradox [PDF]
, 2014 A. N. Turing’s 1936 concept of computability, computing machines, and computable binary digital sequences, is subject to Turing’s Cardinality Paradox. The paradox conjoins two opposed but comparably powerful lines of argument, supporting the propositions

Fixed cardinality stable sets [PDF]
, 2021 Given an undirected graph G=(V,E) and a positive integer k in {1, ..., |V|}, we initiate the combinatorial study of stable sets of cardinality exactly k in G.

Cardinality-constrained Portfolio Selection via Two-timescale Duplex Neurodynamic Optimization
, 2022 This paper addresses portfolio selection based on neurodynamic optimization. The portfolio selection problem is formulated as a biconvex optimization problem with a variable weight in the Markowitz risk–return framework.

Annals of Pure and Applied Logic, 2006 A topological space \(X\) is called scattered provided that every subspace of \(X\) contains an isolated point. Let \(X\) be a locally compact scattered (LCS) topological space. Let \(I_{0}(X)\) be the set of all isolated points of \(X\), and for an ordinal \(\alpha\) define \(I_{\alpha}(X)\) to be the set of all isolated points of the subspace \(X ...

Jónsson cardinals, Erdős cardinals, and the core model [PDF]
Journal of Symbolic Logic, 1999 AbstractWe show that if there is no inner model with a Woodin cardinal and the Steel core model K exists, then every Jónsson cardinal is Ramsey in K, and every δ-Jónsson cardinal is δ5-Erdős in K.In the absence of the Steel core model K we prove the same conclusion for any model L[] such that either V = L[] is the minimal model for a Woodin cardinal ...
