Carbon dioxide and fruit odor transduction in Drosophila olfactory neurons. What controls their dynamic properties? [PDF]
, 2014 We measured frequency response functions between odorants and action potentials in two types of neurons in Drosophila antennal basiconic sensilla. CO2 was used to stimulate ab1C neurons, and the fruit odor ethyl butyrate was used to stimulate ab3A ...

Power Reserve from Photovoltaics for Improving Frequency Response in the Isolated System
Energies, 2023 Appropriate frequency response is an issue of great importance in power system management, especially in an islanded one. An energy-based method for assessing a system’s response, which is needed to prevent under frequency load shedding (UFLS), is ...

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]
, 2014 An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...
