Many measurement applications require converting a slowly varying analog signal into digital with high accuracy and linearity. These often occur in industrial control, environmental monitoring, ...

Patch-clamp recording techniques have revolutionized understanding of the function and sub-cellular location of ion channels in excitable cells. The cell-attached patch-clamp configuration represents ...

In a research paper published in June, researchers at the National Institute of Standards and Technology (NIST) and SEMATECH describe an improved method for determining nanoscale "linewidth roughness, ...

Cuff-based blood pressure monitors (the 'gold standard') can underestimate systolic pressure, meaning many cases of high blood pressure may go undetected. A new physical model using realistic artery ...

A few months ago, when the OPERA Collaboration announced that they had measured neutrinos travelling faster than the speed of light, I was immediately skeptical. That result, if true, would mean that ...

Many recent empirical investment studies have found that the investment of financially constrained firms responds strongly to cash flow. Paralleling these findings is the disappointing performance of ...
