Most football fans have seen players get hit so hard they can barely walk back to the sideline. All too often in years past, those players were back on the field just a few plays later, despite suffer...
Nano-SPEARs gently measure electrical signals in small animals
Nano-SPEARs gently measure electrical signals small animals
2017/4/27
Microscopic probes developed at Rice University have simplified the process of measuring electrical activity in individual cells of small living animals. The technique allows a single animal like a wo...
UCLA scientists show how to amplify or stifle signals for immune responses
UCLA scientists amplify stifle signals immune responses
2017/3/30
T cells, the managers of our immune systems, spend their days shaking hands with another type of cell that presents small pieces of protein from pathogens or cancerous cells to the T cell. But each T ...
Algorithms for the inversion of lidar signals: Rayleigh-Mie measurements in the stratosphere
lidar dial ozone aerosol temperature
2015/10/8
We report the features and the performances of the algorithms, developed at the Lidar Station of L'Aquila, for retrieving atmospheric parameters and constituents from elastic lidar signals. The algori...
Best-basis analysis of broadband tremor signals
adaptive spectrogram analysis broadband tremor
2015/10/8
Active volcanoes usually generate highly non-stationary broadband tremor signals. Short-time shock events with a frequency content of several decades are superimposed on a stationary narrow band conti...
Spectrogram analysis of selected tremor signals using short-time Fourier transform and continuous wavelet transform
spectrogram wavelet transform broadband tremor
2015/10/8
Among a variety of spectrogram methods Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) were selected to analyse transients in non-stationary tremor signals. Depending on the...
Investigating the temporal fluctuations in geoelectrical and geochemical signals Jointly measured in a seismic area of Southern Apennine chain (Italy)
geoelectrical and geochemical signal scaling power spectral analysis
2015/9/28
We analyse geoelectrical and geochemical time series jointly measured by means of a multiparametric automatic station close to an anomalous fluid emission in Val d'Agri (Basilicata, Southern Italy). I...
A new multiparametric geophysicalstation to detect self-potentialand seismometric signals at Tito site(Southern Italy)
self-potential signal earthquake extreme events
2015/9/28
In this work we present the main features of a new multiparametric station able to jointly detect self-potential and seismometric signals in a seismic active area of Southern Italy. The new station ha...
Self-potential chenges associated with volcanic activity:Short-term signals associated with March 9,1998 eruption on La Fournaise volcano (Reunion Island)
self-potential electric precursor ULF band self-potential mapping eruption
2015/9/28
After six years of quietness La Fournaise volcano entered into activity on March 9, 1998. Fissures opened gradually downwards on the northern flank of the cone. Two cones, Kapor and Krafft built, from...
