For four decades, a quiet boundary in pure mathematics kept a powerful theorem locked inside the safe world of finite quantities. Now a new result known as Sebestyen’s theorem has pushed that boundary ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

Yosra Barkaoui’s doctoral dissertation in mathematics at the University of Vaasa, Finland, has successfully generalised a fundamental theorem that has been limited to the bounded case. The research ...

A classic math rule now handles infinity. New work strengthens the math behind physics and unbounded systems. % ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

Understand Thevenin’s Theorem the easy way with a clear, step-by-step circuit example. Learn how to simplify complex electrical networks into an equivalent circuit, making analysis faster and ...

Abstract: Hyperspectral remote sensing images (HSIs) have unique advantages in urban planning, precision agriculture, and ecology monitoring since they provide rich spectral information. However, ...

Abstract: Spectral computed tomography (CT) has recently emerged as an advanced version of medical CT and significantly improves conventional (single-energy) CT. Spectral CT has two main forms: 1) ...

Individual aseismic areas move as rigid plates on the surface of a sphere. Application of the Mercator projection to slip vectors shows that the paving stone theory of world tectonics is correct and ...
