Multispectral tracing in densely labeled mouse brain with nTracer.

Summary: This note describes nTracer, an ImageJ plug-in for user-guided, semi-automated tracing of multispectral fluorescent tissue samples. This approach allows for rapid and accurate reconstruction of whole cell morphology of large neuronal populations in densely labeled brains.

Availability And Implementation: nTracer was written as a plug-in for the open source image processing software ImageJ.

The thermodynamic origin of hysteresis in insertion batteries.

Lithium batteries are considered the key storage devices for most emerging green technologies such as wind and solar technologies or hybrid and plug-in electric vehicles. Despite the tremendous recent advances in battery research, surprisingly, several fundamental issues of increasing practical importance have not been adequately tackled. One such issue concerns the energy efficiency.
