NMR in Biomedicine, Volume 39, Issue 11, November 2026.In two session per volunteer–fasting control and meal activation–, the volunteers underwent repeated multi‐echo gradient echo acquisitions, which were subsequently processed offline with reconstruction of the source images, water‐fat separation with T2*$$ {{\mathrm{T}}_2}^{\ast } $$ mapping, affine registration, and automated segmentation of three ...

Nucleophilic Aromatic Substitution in the Gas Phase
Journal of Physical Organic Chemistry, Volume 39, Issue 11, November 2026.In this review, we highlight experimental studies of gas‐phase SNAr. Studying reactions in the gas phase provides invaluable information on intrinsic reactivity by eliminating the complications of solvent effects. Because SNAr is a fundamental reaction in chemical research and organic synthesis, understanding its underlying reactivity and mechanisms is

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere
Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

New Beam Dynamics Code for Cyclotron Analysis
This paper describes the beam dynamic simulation with transfer matrix method for cyclotron. Starting from a description on the equation of motion in the cyclotron, lattice functions were determined from transfer matrix method and the solutions for the ...

Reconnection Onset in Overstretched Thin Current Sheets: 3‐D Kinetic Picture
Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.Abstract Evolution of the magnetotail equilibrium, whose current density iso‐contours are stretched beyond the magnetic field lines due to small ion anisotropy and agyrotropic effects on the scales of the thermal ion gyroradius (the so‐called overstretched thin current sheet) is considered using 3‐D explicit particle‐in‐cell simulations.

A Data‐Driven Model of the Geomagnetic Storm Recovery Phase
Space Weather, Volume 24, Issue 11, November 2026.Abstract The recovery phase of geomagnetic storms poses a significant challenge for accurate space weather forecasting. Traditional models based on a constant decay rate fail to capture its prolonged and variable duration, leading to uncertainties in predicting impacts on technological systems.

A Study of Kelvin‐Helmholtz Instability at Unmagnetized Planets by Finite Larmor Radius MHD
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Kelvin–Helmholtz instability (KHI) at unmagnetized planetary ionopauses plays a key role in driving solar wind–ionosphere coupling and planetary ion escape. We investigate KHI using a two‐dimensional finite Larmor radius (FLR) MHD model.
