Pickup Ion Modulation on Plateau-like Turbulence in the Martian Magnetosheath

The Astrophysical Journal
The distribution of magnetic energy across scales, represented by the turbulence spectrum, provides insights into magnetic field dynamics in astrophysical and space plasma.

The Pickup Ion-mediated Solar Wind

The Astrophysical Journal, 2018
Abstract The New Horizons Solar Wind Around Pluto (NH SWAP) instrument has provided the first direct observations of interstellar and He pickup ions (PUIs) at distances between ∼11.26 and 38 au in the solar ...

Concurrent uncertainties and investments: Offset effect of Brexit and COVID‐19 on SME growth

European Management Review, EarlyView.
Abstract This study investigates the impact of uncertainty driven by dual crises, regulatory/institutional uncertainty (illustrated by Brexit) and market/operational uncertainty (illustrated by the COVID‐19 pandemic), on the growth trajectories of SMEs. Using Real Options Theory as a guiding framework, hypotheses are developed to examine how investment

Study of pickup of cometary ions in turbulent solar winds [PDF]

, 1987
The influence of moderately strong magnetic disturbances on the ion pickup process near a comet is studied by a test-particle method. The research is motivated by recent observations with ICE and Giotto at Giacobini-Zinner and Halley.

Short-term variability of inner-source pickup ions at 1 AU [PDF]

, 2015
Context. In 1995 a second extended source of pickup ions in the inner heliosphere was discovered. Since then this so-called inner source has been characterised in many studies, and various scenarios for its nature have been proposed. But to this day, the

Lunar Dayside Surface Potentials in the Terrestrial Magnetotail Inferred From Comparing Observed and Modeled Photoelectrons

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract As an airless body, the lunar surface is charged as a result of balancing electric currents into and away from the surface. Lunar surface charging is important for both scientific and human‐exploration purposes. The nightside surface charging has been well characterized by previous studies, but less so for the dayside.

Optical stochastic cooling for RHIC using optical parametric amplification

Physical Review Special Topics. Accelerators and Beams, 2004
We propose using an optical parametric amplifier, with a ∼12   μm wavelength, for optical-stochastic cooling of ^{79}Au ions in the Relativistic Heavy Ion Collider.

Modification of the Transcription Factor FOXL2 at Serines 101 and 107 Disables DNA Binding, Leads to Nucleolar Relocalization, and Rewires Granulosa‐Cell Programs

The FASEB Journal, Volume 40, Issue 15, 15 August 2026.
PKC‐mediated phosphorylation of FOXL2 weakens DNA binding, alters subnuclear localization and protein interactions, and reshapes FOXL2‐dependent transcriptional programs in granulosa cells, supporting a reversible mechanism that modulates FOXL2 activity through phosphorylation of its DNA‐binding domain. ABSTRACT FOXL2 is a forkhead transcription factor

Studies of Interstellar Pickup Ions in the Solar Wind [PDF]

, 1996
The work under this grant involves studies of the interaction of interstellar pickup ions with the solar wind, with the goal of a comprehensive model of the particle distributions and wave intensities to be expected throughout the heliosphere, as well as

VOYAGER OBSERVATIONS OF MAGNETIC WAVES DUE TO NEWBORN INTERSTELLAR PICKUP IONS: 2–6 au [PDF]

, 2016
We report observations by the Voyager 1 and 2 spacecraft of low-frequency magnetic waves excited by newborn interstellar pickup ions H⁺ and He⁺ during 1978–1979 when the spacecraft were in the range from 2 to 6.3 au.
