Abstract Rejuvenating galaxies are unusual that fully quench and then subsequently experience a “rejuvenation” event to become star-forming once more. Rejuvenation rates vary substantially in models of galaxy formation: 10%–70% massive expected rejuvenation by z = 0. Measuring the rate is therefore important for calibrating strength star-formation feedback mechanisms. However, these observation...

A high-resolution human in vivo spectroscopic image was obtained using the 2.0-T NMR imaging system developed at KAIS (Korea Advanced Institute of Science). The in vivo spectroscopic image obtained has high spatial resolution as well as spectral resolution good enough for extraction of the detailed spectroscopic information. This high-resolution spectroscopic imaging was made possible by use of...

The recent development of Fourier transform infrared (FTIR) spectroscopic imaging has enhanced our capability to examine, on a microscopic scale, the spatial distribution of vibrational spectroscopic signatures of materials spanning the physical and biomedical disciplines. Recent activity in this emerging area has concentrated on instrumentation development, theoretical analyses to provide guid...

We present the realisation of near-field spectroscopic measurements with fibre-tip-based scanning near-field microscopy. It allows simultaneous acquisition of near-field optical images in a broad spectral range (400 nm to 1000 nm), thus recovering local spectroscopic information. The technique is essential for understanding the resonant interaction of light with nanostructured objects as the fa...

Bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. In this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. The structure and bioactivity of these samples based on their interaction with simulated body fluid (SBF) have been determined. In-vitor, using the Raman s...

PURPOSE To develop a robust and rapid imaging technique for hyperpolarized (13)C MR Spectroscopic Imaging and investigate its performance. METHODS A concentric rings readout trajectory with constant angular velocity is proposed for hyperpolarized (13)C spectroscopic imaging and its properties are analyzed. Quantitative analyses of design tradeoffs are presented for several imaging scenarios. ...
