On the Adjoint Operator in Photoacoustic Tomography [PDF]
, 2016 Photoacoustic Tomography (PAT) is an emerging biomedical "imaging from coupled physics" technique, in which the image contrast is due to optical absorption, but the information is carried to the surface of the tissue as ultrasound pulses. Many algorithms

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]
, 2020 We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...

Estimating the Rayleigh-Wave Impulse Response Between Seismic Stations with the Cross Terms of the Green Tensor [PDF]
, 2011 The development of ambient noise tomography has provided a powerful tool to investigate the Earth\u27s subsurface with increased resolution. Most commonly, surface-wave tomography is performed on inter-station estimates of the vertical component of ...

Ambient noise tomography of El Hierro island (Canary Islands)
Frontiers in Earth ScienceEl Hierro island is one of the most active islands in the Canary Islands from a volcanological point of view. This is the reason why the imaging of the internal crustal structure is of huge importance.

Ambient noise Rayleigh wave tomography across Europe [PDF]
Geophysical Journal International, 2007 SUMMARY We extend ambient noise surface wave tomography both in bandwidth (10‐50 s period) and in geographical extent (across much of Europe) compared with previous applications. 12 months of ambient noise data from 2004 are analysed. The data are recorded at about 125 broadband Seismic stations from the Global Seismic Network and the Orfeus Virtual ...

Molecular Oncology, EarlyView.This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
