Low-Frequency Modulation Sensors Using Nanosecond Fluorophores

Multi-frequency Temperature Modulation for Metal-oxide Gas Sensors

This article presents an empirical study of temperature modulation for metal-oxide gas sensors at multiple frequencies ranging from 0.125Hz to 4Hz. Commercial metal-oxide sensors from two manufacturers were exposed to analyte concentrations below their isothermal discrimination threshold over a period of ten days. The results reported in this article indicate that temperature modulation can sig...

Low Rate High Frequency Data Transmission from Very Remote Sensors

Monitoring of Regional Low-Flow Frequency Using Artificial Neural Networks

Ecosystem of arid and semiarid regions of the world, much of the country lies in the sensitive and fragile environment Canvases are that factors in the extinction and destruction are easily destroyed in this paper, artificial neural networks (ANNs) are introduced to obtain improved regional low-flow estimates at ungauged sites. A multilayer perceptron (MLP) network is used to identify the funct...

Low-Frequency Noise Impact on CMOS Image Sensors

CMOS image sensors are nowadays extensively used in imaging applications even for high-end applications. This is really possible thanks to a reduction of noise obtained, among others, by Correlated Double Sampling (CDS) readout. Random Telegraph Signal (RTS) noise has thus become an issue for low light level applications especially in the context of downscaling transistor size. This paper descr...

Differential Nanosecond Protein Dynamics in Homologous Calcium Sensors.

Shaping the temporal response of photoreceptors is facilitated by a well-balanced second messenger cascade, in which two neuronal Ca(2+)-sensor proteins operate in a sequential relay mechanism. Although they share structurally similar sensing units, they differentially activate the same target protein. Here, as a prototypical case in Ca(2+)-mediated signal processing, we investigate differentia...
