We provide a simple geometric explanation for the source of switchbacks and associated large one-sided transverse flows in solar wind observed by Parker Solar Probe. The more radial, Sub-Parker Spiral structure heliospheric magnetic field previously Ulysses, ACE, STEREO is created within rarefaction regions where footpoint motion from fast into slow at Sun creates line connection across speed s...

Andrew Paterson discusses findings from a new study that shows HbA1c screening for diabetes will leave 2% of African Americans undiagnosed and how personalised medicine is needed.

Cellular Landscapes. Many ABM/LUCC researchers begin by developing models that operate over an abstract landscape, even when their longer-term goals include application to real-world landscapes. Roles for abstract ABM/LUCC models are discussed by Parker and colleagues (Parker, Berger, and Manson 2002 a,b; Parker, Manson, and Berger 2002; Parker et al. 2003), and the advantages of a progression ...

A linear stability analysis has been performed onto a self-gravitating magnetized gas disk bounded by external pressure. The resulting dispersion relation is fully explained by three kinds of instability: a Parker-type instability driven by self-gravity, usual Jeans gravitational instability and convection. In the direction parallel to the magnetic fields, the magnetic tension completely suppre...
