In open field arenas, Drosophila adults exhibit a preference for arena boundaries over internal walls and open regions. Herein, we investigate the nature of this preference using phenomenological modeling of locomotion to determine whether local aren

BACKGROUND: Difficulties associated with implementing gene therapy are caused by the complexity of the underlying regulatory networks. The forms of interactions between the hundreds of genes, proteins, and metabolites in these networks are not known

Turbulent flows have been the subject of intensive studies, but experimental investigations are lacking due to the need for high-frequency and high-resolution methods to probe small scale structure and time evolution. The authors report high repetiti

In this paper, we introduce a model-free algorithm, robust mode analysis (RMA), to extract primary constituents in a fluid or reacting flow directly from high-frequency, high-resolution experimental data. It is expected to be particularly useful in s

We study the formation of images in a reflective sphere in three configurations using caustics on the field of light rays. The optical wavefront emerging from a source point reaching a subject following passage through the optical system is, in gener

We propose a novel methodology for high-dimensional time series prediction based on the kernel method extension of data-driven Koopman spectral analysis, via the following methodological advances: (a) a new numerical regularization method, (b) a natu
