چکیده

Previous results on the use of joint entropy for detection of targeted nanoparticles accumulating in the neovasculature of MDA435 tumors [Fig. 7 of M. S. Hughes et al., J. Acoust. Soc. Am. 133, 283-300 (2013)] are extended, with sensitivity improving by nearly another factor of 2. This result is obtained using a "quasi-optimal" reference waveform in the computation of the joint entropy imaging technique used to image the accumulating nanoparticles.

Joint entropy of continuously differentiable ultrasonic waveforms.

This study is based on an extension of the concept of joint entropy of two random variables to continuous functions, such as backscattered ultrasound. For two continuous random variables, X and Y, the joint probability density p(x,y) is ordinarily a continuous function of x and y that takes on values in a two dimensional region of the real plane. However, in the case where X=f(t) and Y=g(t) are...

Application of Renyi entropy for ultrasonic molecular imaging.

Previous work has demonstrated that a signal receiver based on a limiting form of the Shannon entropy is, in certain settings, more sensitive to subtle changes in scattering architecture than conventional energy-based signal receivers [M. S. Hughes et al., J. Acoust. Soc. Am. 121, 3542-3557 (2007)]. In this paper new results are presented demonstrating further improvements in sensitivity using ...

Comments on ‘‘Effects of bandwidth on glottal airflow waveforms estimated by inverse filtering’’ [J. Acoust. Soc. Am. 98, 763–767 (1995)]

In the subject paper @Alku and Vilkman, J. Acoust. Soc. Am. 98, 763–767 ~1995!; hence AV#, AV describe the results of their research on the effect of bandwidth on estimated voice source parameters. They found that reducing the bandwidth ~by low-pass filtering the glottal flow signals! leads to a distortion of the estimated parameters. Although I do agree that low-pass filtering influences the e...

Spectral and temporal resolutions of information-bearing acoustic changes for understanding vocoded sentences.

Short-time spectral changes in the speech signal are important for understanding noise-vocoded sentences. These information-bearing acoustic changes, measured using cochlea-scaled entropy in cochlear implant simulations [CSECI; Stilp et al. (2013). J. Acoust. Soc. Am. 133(2), EL136-EL141; Stilp (2014). J. Acoust. Soc. Am. 135(3), 1518-1529], may offer better understanding of speech perception b...
