Direct solar coronal magnetic field measurements have become possible since recent development of high-sensitivity infrared detection technology. The SOLARC instrument installed on Mt. Haleakala is such a polarimetric coronagraph that was designed for routinely observing Stokes parameter profiles in near infrared (NIR) wavelengthes. The Fe 1075 nm forbidden coronal emission line (CEL) is potent...

Thin (5-mm) coronal high-field (1.5-T) MR images of four human brain specimens and 14 normal volunteers were correlated with myelin-stained microtomic sections of the specimen cerebella. The primary white-matter tracts innervating several hemispheric (posterior quadrangular, superior, and inferior semilunar, gracile, biventer, tonsil) and vermian (declive, folium, tuber) lobules are oriented pe...

In many languages that permit coronal laterals to follow labial and velar stops in complex onsets, sequences of a coronal stop followed by a coronal lateral are prohibited. Standard accounts rule out coronal-lateral clusters as an effect of the Obligatory Contour Principle, but this approach cannot explain languages such as Mong Njua and Katu, which neutralize the coronal-velar place contrast b...

Recent advances have made it possible to obtain two-dimensional line-of-sight magnetic field maps of the solar corona from spectropolarimetric observations of the Fe XIII 1075 nm forbidden coronal emission line. Together with the linear polarization measurements that map the azimuthal direction of the coronal magnetic field projected in the plane of the sky containing Sun center, these coronal ...

The X-ray corona is richly structured with individual plasma loops. A model is presented explaining these loops as the sites of magnetic energy storage and sporadic release. Energy is stored as coronal currents driven inductively by motions at the photosphere. These currents occur at internal boundaries in the coronal eld called separator. A method is described for completely characterizing the...

We have developed a steady-state energy balance model of the solar corona, which calculates coronal magnetic field structure and thermodynamics from a photospheric magnetogram. Our method involves a solution of energy and momentum equations along individual coronal loops, allowing for flows, gravity, non-uniform heating, and cross-sectional area variations. The model yields predicted plasma emi...

We explore robust methods of automatically quantifying constriction location, constriction degree and gestural kinematics of Italian short and long consonants using direct image analysis techniques applied to rtMRI data. Articulatory kinematics are estimated from correlated regional changes in pixel intensity. We demonstrate that these methods are capable of quantifying differences in constrict...
