Abstract: Graph filtering is a fundamental tool in graph signal processing. Polynomial graph filters (PGFs), defined as polynomials of a fundamental graph operator, can be implemented in the vertex ...

One powerful way to do this is through a routine called slow reveal graphs.

Two mathematicians have proved that a straightforward question — how hard is it to untie a knot? — has a complicated answer.

The platform, Degree Intelligence, suggests classes for users based on information about their majors and transcripts.

The time it takes to earn a Ph.D. can range from a few years to around a decade. You'll likely face many hurdles on the long educational journey. Whether it's worth the time and cost depends on your ...

Since the 1970s, astronomers have predicted that Sagittarius A*, the supermassive black hole at the centre of the Milky Way, ...

A scaling law relates the expected number of mutants to the total population size of cells in a spatially constrained but ...

Volatility is often called the fear gauge of the options market. When fear rises, volatility spikes — premiums get expensive, risks increase, and opportunities can shift in an instant. When markets ...

Why do glass and other amorphous materials deform more easily in some regions than in others? A research team from the University of Osaka, the National Institute of Advanced Industrial Science and ...

At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.

Abstract: Understanding the underlying graph structure of a nonlinear map over a particular domain is essential in evaluating its potential for real applications. In this paper, we investigate the ...

Specialists caution that there isn’t a universal portrait that captures the state of higher education around the world.
