Sono-photoacoustic imaging of gold nanoemulsions: Part I. Exposure thresholds

Integrating high contrast bubbles from ultrasound imaging with plasmonic absorbers from photoacoustic imaging is investigated. Nanoemulsion beads coated with gold nanopsheres (NEB-GNS) are excited with simultaneous light (transient heat at the GNS's) and ultrasound (rarefactional pressure) resulting in a phase transition achievable under different scenarios, enhancing laser-induced acoustic sig...

A new case of TEMPI syndrome

We present an interesting case of a woman with new onset hypertension and abdominal fullness who was found to have huge bilateral perinephric fluid collections. Extensive workup revealed that she had secondary polycythemia, extensive truncal and proximal extremities telangiectasia and IgA-lambda monoclonal gammopathy of underdetermined significance. We believe that this is one of the rare cases...

Robust Detection of Sono

A sonorant detection scheme using Mel-frequency cepstral coefficients and support vector machines (SVMs) is presented and tested in a variety of noise conditions. Adapting the classifier threshold using an estimate of the noise level is used to bias the classifier to effectively compensate for mismatched training and testing conditions. The adaptive threshold classifier achieves low frame error...
