Classic techniques like videofluoroscopy, stationary manometry, and ambulatory 24 h pH-metry are routinely used in the clinic to study patients with dysphagia, chest pain and reflux-related symptoms.

Approximately 50% of patients with GERD-like symptoms have no evidence of acid reflux on endoscopy and 24 h pH testing. New research shows that multichannel intraluminal impedance (MII) pH testing ...

The global issue of antimicrobial resistance has been called a “slow motion catastrophe” resulting from the excessive and often inappropriate use of antibiotics to fight bacterial infections. 1 A long ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Electrochemical impedance spectroscopy (EIS) is used in this procedure to test the impedance in a commercial battery after connecting it two ways. An analysis of the differences in the obtained values ...

Keysight Technologies today introduced three low-frequency options for its E4982A LCR meter. With these new options, the E4982A is suited for RF inductor, coil, and EMI filter manufacturers that are ...
