New interpretation of ion cyclotron emission from a tokamak

Physics of Plasmas
The tempting interpretation of ion cyclotron emission in terms of compressional Alfvén eigenmodes involving energetic ions is inconsistent with recent TCV experimental observations in some important aspects, such as (i) the perturbed poloidal field is exceeding the parallel perturbed magnetic field significantly, and (ii) the modes are near cyclotron ...

Free‐Breathing Hepatic Oxygen Extraction Fraction (OEF) Mapping Using Radial GESSE

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2840-2847, December 2026.
ABSTRACT Purpose Noninvasive assessment of hepatic oxygenation is relevant for evaluating liver both in acute and long‐term liver pathologies. However, existing methods are limited to single‐slice acquisitions and require breath‐holding. This study aims to develop and evaluate a motion‐robust technique for whole‐liver oxygen extraction fraction (OEF ...

Relative affinity constants by electrospray ionization and Fourier transform ion cyclotron resonance mass spectrometry: calmodulin binding to peptide analogs of myosin light chain kinase [PDF]

, 2003
Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca2+.

Physics of beam-driven ion cyclotron emission in the large plasma device

Nuclear Fusion
Ion cyclotron emission (ICE) is widely observed from spatially localised minority energetic ion populations in toroidal magnetically confined fusion (MCF) plasmas, both tokamaks and stellarators.

Propagation of ion cyclotron emission in the DIII-D tokamak

Physics of Plasmas
Experiments in L- and H-mode plasmas performed on the DIII-D tokamak explored ion cyclotron emission (ICE) propagation via the recently upgraded ICE diagnostic. The distance between the plasma and the outer wall was scanned to alter the evanescent region, which was seen to impact the detection of runaway electron-driven whistler modes in a comparable ...

Nightside Auroral Arcs Near the Electron Isotropy Boundary: TRACERS–THEMIS–MetOp Observations

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Particle precipitation is the ultimate driver of aurorae. Monoenergetic (∼keV) electrons accelerated above the ionosphere produce discrete auroral forms and are associated with field‐aligned currents that govern magnetosphere–ionosphere (MI) coupling.

Narrow-band emission with 0.5 to 3.5 Hz varying frequency in the background of the main phase of the 17 March 2013 magnetic storm

Solar-Terrestrial Physics, 2016
We present results of the analysis of an unusually long narrow-band emission in the Pc1 range with increasing carrier frequency. The event was observed against the background of the main phase of a strong magnetic storm caused by arrival of a high-speed ...

Establishing a Fluorescence‐Size Correlation Methodology for Small‐Molecule Nanoassembly Evaluation

Aggregate, Volume 7, Issue 11, November 2026.
Schematic illustration of aggregation‐induced emission‐enabled nanoassembly (NA) evaluation methodology. A two‐dimensional model coupling fluorescence and particle size was developed to evaluate NA properties and validated by in vitro assembly ability analysis and in vivo pharmacokinetic study.

Relativistic-electron dropouts and recovery: A superposed epoch study of the magnetosphere and the solar wind [PDF]

, 2009
During 124 high-speed-stream-driven storms from two solar cycles, a multispacecraft average of the 1.1–1.5 MeV electron flux measured at geosynchronous orbit is examined to study global dropouts of the flux. Solar wind and magnetospheric measurements are

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

Mass Spectrometry Reviews, Volume 45, Issue 6, Page 1064-1086, November/December 2026.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is
