Impact of COVID-19 restrictions on the research environment and motivation of researchers in Japan

open access: yesProgress in Disaster Science, 2020
The environment surrounding researchers has changed significantly in the face of COVID-19 restrictions. An online self-reported questionnaire was completed by 10,557 participants between June 15 and 19, 2020.

Magnetic Field Uniformity Across the GF 9-2 YSO, L1082C Dense Core, and GF 9 Filamentary Dark Cloud [PDF]

open access: yes, 2018
The orientation of the magnetic field (B-field) in the filamentary dark cloud GF 9 was traced from the periphery of the cloud into the L1082C dense core that contains the low-mass, low-luminosity Class 0 young stellar object (YSO) GF 9-2 (IRAS 20503+6006)

Super black hole as spinning particle: Supersymmetric baglike core [PDF]

open access: yes, 2001
We consider particlelike solutions to supergravity based on the Kerr-Newman black hole (BH) solution. The BH singularity is regularized by means of a phase transition to a new vacuum state near the core region confining a dual gauge field. Supersymmetric

Influence of different data selection criteria on internal geomagnetic field modeling

open access: yesEarth and Planetary Physics
Earth’s internal core and crustal magnetic fields, as measured by geomagnetic satellites like MSS-1 (Macau Science Satellite-1) and Swarm, are vital for understanding core dynamics and tectonic evolution.

Field dependence of the vortex core size in a multi-band superconductor

open access: yes, 2005
The magnetic field dependence of the vortex core size in the multi-band superconductor NbSe2 has been determined from muon spin rotation measurements. The spatially extended nature of the quasiparticle core states associated with the smaller gap leads to

A new high-resolution geomagnetic field model for southern Africa

open access: yesSouth African Journal of Science
Earth’s magnetic field is a dynamic, changing phenomenon. The geomagnetic field consists of contributions from several sources, of which the main field originating in Earth’s core makes up the bulk.

Ultrafast annular-magnetic-field-driven vortex-core reversals

open access: yesAIP Advances, 2016
By micromagnetic numerical simulations, we investigate the dynamics of vortex-core reversal in a soft magnetic nanodisk under the excitation of annular, perpendicular, resonant magnetic fields.

Magnetic Field Structure around Low-Mass Class 0 Protostars: B335, L1527 and IC348-SMM2

open access: yes, 2011
We report new 350 micron polarization observations of the thermal dust emission from the cores surrounding the low-mass, Class 0 YSOs L1527, IC348-SMM2 and B335.

Magnetars: Time Evolution, Superfluid Properties, and Mechanism of Magnetic Field Decay [PDF]

open access: yes, 2004
We calculate the coupled thermal evolution and magnetic field decay in relativistic model neutron stars threaded by superstrong magnetic fields (B > 10^{15} G).

Earth's Inner Core dynamics induced by the Lorentz force [PDF]

open access: yes, 2015
Seismic studies indicate that the Earth's inner core has a complex structure and exhibits a strong elastic anisotropy with a cylindrical symmetry. Among the various models which have been proposed to explain this anisotropy, one class of models considers
