Our paper about estimation of phase-pole-free images for parallel magnetic resonance imaging using nonlinear inversion is now online. This method finally solves an outstanding and annoying problem in this area in a rather elegant way.

![17th-century representation of consciousness by Robert Fludd, an English Paracelsian physician
Robert Fludd - Utriusque cosmi maioris scilicet et minoris […] historia, tomus II (1619), tractatus I, sectio I, liber X, De triplici animae in corpore visione
This is an early modern representation of consciousness and perception, showing how the mind processes information from the senses and connects with both the physical and spiritual realms:
The human profile: Represents the individual person as the microcosm
Circles emanating from the head: Different faculties of the mind and soul
"Mundus sensibilis" (Sensible/Physical World) - the realm of the senses
"Mundus Intellectualis" (Intellectual World) - the realm of reason and understanding
Various spheres labeled with Latin terms for different mental faculties
"Terra" (Earth) appears in multiple circles, showing levels of understanding
Top section: "Mundus Intellectualis" with "DEUS" (God) at the center, surrounded by angels and spiritual hierarchies
The eye: Representing vision and perception
Connections: Lines showing how sensory information flows from the physical world through the senses to higher understanding
