With negative slope the line moves down when going from left to right. If two linear functions have the same slope they are parallel. Slopes of linear functions The slope of a linear function is the ...

The paper is concerned with the stability analysis of positive feedback interconnections of negative imaginary systems. Firstly, a previously established Negative Imaginary Lemma is shown to remain ...

The note is concerned with linear negative imaginary systems. First, a previously established Negative Imaginary Lemma is shown to remain true even if the system transfer function matrix has poles on ...

Gradientless light fields are shown to exert pulling forces on arbitrary objects in purely passive dielectric media. These forces arise from amplification of the photon linear momentum when light ...
