Protective effects of detergent-treated outer membrane vesicles (D-OMVs) prepared from the parent group B M986 strain and the nonencapsulated M986-NCV mutant in myelosuppressed mice were investigated in models of experimental septic shock. The effect

A 200 km anomalous topographic zone was discovered using wavelet scale analysis in a 1600 km linear bathymetric profile taken northeast of Hawaii. A spectral analysis of the zone shows that the power in wavelengths shorter than 25 km averages 5–10

Classification and characterization of text is of ever growing importance in defense and national security. The text classification task is an instance of classification using sparse features residing in a high dimensional feature space. Two standard

In active sonar the acoustic backscatter may contain multiple specular components, resonant components, Gaussian, reverberation and other noises as well as multipath effects. One purpose of sonar signal processing is to extract information from the b

A new feature for the classification of echoes of a transmitted signal based on the generalized target description is described, and a framework for adaptive classification using it is presented. The generalized target description is a parametric mod

Time‐frequency and time‐scale techniques are appropriate to the analysis of signals which are broadband and highly non‐stationary. These techniques are used to analyze unique features of noise data from a transient pipe flow experiment.

Short, high frequency bursts are found in flow noise data from a transient regime in a pipe flow experiment. These bursts are directly detectable in accelerometer measurements, but processing is necessary to detect them in synchronous hydroacoustic m

We evaluate via numerical simulation the performance of a detection algorithm applicable to unknown transients in acoustic signals. This is a filter-then-detect scheme in which the filtering is accomplished by thresholding in the wavelet domain. The

We describe the implementation of a wavelet based transient detection algorithm and compare its performance with that of traditional Fourier techniques via a numerical simulation. The wavelet algorithm is a filter‐then‐detect algorithm; the filte

The wavelet transform is a bank of convolution filters indexed by scale; each scale of the transform of a signal is a filtered version of that signal. Here we explore the use of the Morlet wavelet to filter one coordinate of a dynamical system in ord
