When we decided to become electronics engineers, we were introduced to Ohm's Law and to two enshrined methods of analyzing circuits. These were called “loop analysis” and “node analysis.” We were told ...

Detection of metastatic spread of head and neck cancer to cervical lymph nodes is essential for optimal design of therapy. Undetected metastases lead to mortality, which can be prevented by better ...

Based on a presentation to the 57th Southwestern Petroleum Short Course, Lubbock, Tex., Apr. 26-29, 2010. As shown with a nodal analysis, the use of wellhead chokes on electrical submersible-pumped ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

Accurate detection of lymph-node metastases in prostate cancer is an essential component of the approach to treatment. We investigated whether highly lymphotropic superparamagnetic nanoparticles, ...
