Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn't believe it would ever be ...

Abstract: Sum of squares (SOS) optimization has been a powerful and influential addition to the theory of optimization in the past decade. Its reliance on relatively large-scale semidefinite ...

The Center for American Progress’ data dashboard allows users to explore national- and state-level data trends on a range of child care and early learning topics. Read more and explore additional ...

As a condition of using these data, you must cite the use of this data set. Such a practice gives credit to data set producers and advances principles of transparency and reproducibility. Other ...

Discriminated unions, also known as sum types, are an invaluable tool for working with heterogenous data types in code. They help ensure safe data access patterns and can make illegal states ...

Given two arrays: arr1[0..m-1] of size m and arr2[0..n-1] of size n. Task is to check whether arr2[] is a subset of arr1[] or not. Both the arrays can be both unsorted or sorted. It may be assumed ...

A new proof illuminates the hidden patterns that emerge when addition becomes impossible. The simplest ideas in mathematics can also be the most perplexing. Take addition. It’s a straightforward ...

Abstract: Non-orthogonal multiple access (NOMA) systems have the potential to deliver higher system throughput, compared with contemporary orthogonal multiple access techniques. For a linearly ...

T-cell receptor (TCR) binding to its ligand(s) is essential for T-cell development into several distinct lineages. The strength of this interaction and physicochemical characteristics of TCR were ...

This Research Topic will give a comprehensive overview of Toxoplasma-host immune response interactions. Most Toxoplasma virulence determinants to date have been established in murine systems and it is ...
