ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Non-Supersymmetric SO(3)-Invariant Deformations of N=1* Vacua and their Dual String Theory Description [PDF]
We study the SO(3)-invariant relevant deformations of N=4 SU(N) gauge theory using the methods of Polchinski and Strassler. We present the region of parameter space where the non-supersymmetric vacuum is still described by stable ``dielectric'' five branes within the supergravity approximation.

Abstract Purpose The detection of hyperpolarized carbon‐13 (HP 13C)‐fumarate conversion to 13C‐malate using 13C‐MRSI is a biomarker for early detection of cellular necrosis. Here, we describe the translation of HP 13C‐fumarate as a novel human imaging agent, including the evaluation of biocompatibility and scaling up of the hyperpolarization methods ...

Development and optimization of human deuterium MR spectroscopic imaging at 3 T in the abdomen
Abstract Purpose To establish and optimize abdominal deuterium MR spectroscopic imaging in conjunction with orally administered 2H‐labeled molecules. Methods A flexible transmit‐receive surface coil was used to image naturally abundant deuterium signal in phantoms and healthy volunteers and after orally administered 2H2O in a patient with a benign ...
