The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form. Find the equation of the line of symmetry and ...

Abstract: Protein structure comparison is one of the most challenging problem in bioinformatics. This problem is modeled as a contact map overlap problem in which the similarity of the two proteins ...

The graphs of \(y = 2x + 1\) and \(y = 2x - 2\) are shown below. The graph of \(y = 2x + 1\) crosses the \(y\)-axis at (0, 1). The graph of \(y = 2x - 2\) crosses the ...

This monograph identifies polytopes that are “combinatorially ℓ 1-embeddable”, within interesting lists of polytopal graphs, i.e. such that corresponding polytopes are either prominent mathematically ...

Rigorous error estimates for amplitude equations are well known for deterministic PDEs, and there is a large body of literature over the past two decades. However ...

Abstract: Bipartite graph is an important data structure that widely exists in disease prevention and control, community detection, and other real-life applications. In a bipartite graph, edges not ...

In this article we show how a Graph Network with attention read and write can perform shortest path calculations. This network performs this task with 99.91% accuracy after minimal training. Here at ...
