Using coronary CT angiography to assess plaque burden—and specifically the burden of “low-attenuation” plaque—in patients presenting with chest pain can help predict the risk of future myocardial ...

Researchers in Japan have used measurements of the aftershocks of the 2011 Tohoku earthquake to gain insight into the dynamics of the Earth’s crust and upper mantle. Nozomu Takeuchi and colleagues at ...

To evaluate whether natural attenuation can achieve legal standards for groundwater cleanup, the fate of contaminants in the groundwater environment has to be well understood. In what direction do the ...

Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers have now derived an equation describing this phenomenon, demonstrating that ...

Measuring attenuation in a fiber-optic cable is a vital ingredient to obtaining the maximum performance from a system designs. But, for designers, just starting to work in the fiber-optic design space ...

Sponsored by: Texas Instruments. Programmable linear equalization coupled with the latest repeater ICs can open up a “clear path” to optimized signal quality. Transmitting high-speed data over a cable ...

This rule of thumb enables us to estimate how much attenuation would be in the loss budget of a serial channel. Spoiler summary:With no equalization, about -10 dB at the Nyquist. With just CTLE, about ...

The weakening of RF energy from an RFID tag or reader. The energy emitted by the reader naturally decreases with distance. The rate of decrease is proportional to the inverse square of the distance.
