A three‐level explicit time‐split MacCormack method is proposed for solving the two‐dimensional nonlinear reaction‐diffusion equations. The computational cost is reduced thank to the splitting and the explicit MacCormack scheme.

Fast online deconvolution of calcium imaging data [PDF]
Fluorescent calcium indicators are a popular means for observing the spiking activity of large neuronal populations, but extracting the activity of each neuron from raw fluorescence calcium imaging data is a nontrivial problem.

Molecular rheotaxis directs DNA migration and concentration against a pressure-driven flow
Implementing a nucleic acid preconcentration method can improve the sensitivity of microfluidic analysis systems. Here Friedrich et al. concentrate DNA by many orders of magnitude using pressure-driven flow, which could lead to a simple and practical ...

Efficient Frequency-Dependent Newmark-Beta-FDTD Method for Periodic Grating Calculation
In this paper, the Newmark-Beta algorithm is introduced into the finite-difference time-domain (FDTD) method in dispersion media, resulting in an unconditionally stable method for periodic metallic grating analysis.

What our minds and conceive, our bodies can achieve. I will argue that “the mind is not then an autonomous substance, capable of forming its own states without recourse to what lies beyond it: it states arrive by courtesy of a specific external ...

Three-phase active rectifiers guarantee sinusoidal input currents and unity power factor at the price of a high switching frequency ripple. To adopt an LCL-filter, instead of an L-filter, allows using reduced values for the inductances and so preserving ...

War and Revolution: Friedrich Engels as a Military and Political Thinker
This article explores the link between political and military strategy and tactics in the work of Friedrich Engels. Though widely praised for his understanding of military affairs, Engels’ interlocutors have tended to be dismissive of his political works.
