David Richeson discusses the history and significance of the four color theorem.

This important study presents a new method for longitudinally tracking cells in two-photon imaging data that addresses the specific challenges of imaging neurons in the developing cortex. It provides ...

As analog content is converted to digital, 12-bit allows a maximum representation of 4096 different colors in a single color map. With RGB signals, where a 10-bit color map of up to 4096 different ...

In this study, a networked spatiotemporal chaotic map model is proposed based on the traditional coupled map lattice system. In addition, the time delay and variable topology parameters are considered ...

In this paper, we propose a novel 2D hyperchaotic Sine couple map (2D-HSCM) and then the proposed 2D map is analyzed using bifurcation diagrams, attractor trajectory, Lyapunov exponent, fixed point, ...

The geometric phase has become a foundational element in modern metasurface design for optical phase and wavefront control. Here, we introduce the concept of geometric polarization, in which the ...
