Self-Consistent Heating of the Magnetically Closed Solar Corona: Generation of Nanoflares, Thermodynamic Response of the Plasma and Observational Signatures

C.D. Johnston, L. K. S. Daldorff, J. A. Klimchuk, Shanwlee Sow Mondal et autres

Abstract The energy that heats the magnetically closed solar corona originates in the complex motions of the massive photosphere. Turbulent photospheric convection slowly displaces the footpoints of coronal field lines, causing them to become twisted and tangled. Magnetic stresses gradually build until …

Unfavorable disease progression in patients with chronic myeloid leukemia and concurrent t(6;9) translocation (DEK::NUP214 fusion) or inversion 16 (CBFB::MYH11 fusion)

J. Reid, Deepa Jeyakumar, Kapitolina Semenova, Lisa Lee et autres

The occurrence of additional specific chromosomal abnormalities in Philadelphia chromosome-positive (pH+) cells is associated with disease progression in chronic myeloid leukemia (CML), and is considered a marker that defines the accelerated/blast phase of CML. Both DEK::NUP214 fusion and CBFB rearrangement are extremely …

Quantifying when and where strong magnetic skew forms in a data-driven global non-potential model of the solar corona I: production and persistence of skew

J. Reid, D. H. Mackay, Lisa Upton

ABSTRACT Strong magnetic skew characterizes several non-potential structures in the solar corona, including filaments, which can erupt, producing major geomagnetic effects. Magnetic skew is thus a useful property in understanding locations of free magnetic energy in, and making forecasts from, global coronal …

Aggressive Pediatric Primitive Round Cell Tumors with MN1::ZNF341 Fusion: A Mimic of Neuroblastoma

Serena Y. Tan, Mark G. Evans, Raya Saab, J. Reid et autres

Neuroblastoma is one of the most common tumors in young children, arising from the adrenal medulla or paraspinal sympathetic ganglia. We describe primitive round cell tumors presenting in three patients less than 1.5 years old, with striking clinical and pathologic similarities to …

Case report: High grade serous fallopian tube carcinoma with rare NRG1 gene fusion presenting as widespread peritoneal carcinomatosis

Anthony Crymes, Mark G. Evans, Tolulope Adeyelu, J. Reid et autres

The discovery of gene fusions involving Neuregulin-1 (NRG1) within solid tumors has important therapeutic implications, as they are being actively explored as targets for emerging ERBB/ERBB2/ERBB3-directed anti-cancer agents. NRG1 fusions are very uncommon across all tumor types and are infrequently documented in …

Epstein-Barr virus–positive, primary cutaneous marginal zone lymphoma, with transformation: Case report and review of the literature

Lori Soma, Liliana Crisan, J. Reid, Winston Lee et autres

INTRODUCTION: Epstein-Barr Virus (EBV) positive primary cutaneous marginal zone lymphoma (PCMZL) is uncommon and subsequent transformation is rare. METHODS: We report a patient with EBV positive PCMZL with subsequent transformation to plasmablastic lymphoma and review the literature for transformed PCMZL to assess …

The thermodynamic response of heating at coronal null points

D. Johnson, A. W. Hood, P. J. Cargill, J. Reid et autres

ABSTRACT Magnetic null points are an important aspect of the magnetic field structure of the solar corona and can be sites of enhanced dissipation. This paper uses analytical and numerical models to investigate the plasma structure around a heated null. It is …

Coronal energy release by MHD avalanches

G. Cozzo, J. Reid, P. Pagano, F. Reale et autres

Context. Magnetohydrodynamic (MHD) instabilities, such as the kink instability, can trigger the chaotic fragmentation of a twisted magnetic flux tube into small-scale current sheets that dissipate as aperiodic impulsive heating events. In turn, the instability could propagate as an avalanche to nearby …

Coronal energy release by MHD avalanches II. EUV line emission from a multi-threaded coronal loop

G. Cozzo, J. Reid, P. Pagano, F. Reale et autres

MHD kink instability can trigger the fragmentation of a twisted magnetic flux tube into small-scale current sheets that dissipate as aperiodic impulsive heating events. This instability propagates as an avalanche to nearby flux tubes and leads to a nanoflare storm. Our previous …

Coronal energy release by MHD avalanches

G. Cozzo, J. Reid, P. Pagano, F. Reale et autres

Context. A possible key element for large-scale energy release in the solar corona is a magnetohydrodynamic (MHD) kink instability in a single twisted magnetic flux tube. An initial helical current sheet progressively fragments in a turbulent way into smaller-scale sheets. Dissipation of …

Coronal energy release by MHD avalanches. Effects on a structured, active region, multi-threaded coronal loop

G. Cozzo, J. Reid, P. Pagano, F. Reale et autres

A possible key element for large-scale energy release in the solar corona is an MHD kink instability in a single twisted magnetic flux tube. An initial helical current sheet fragments in a turbulent way into smaller-scale sheets, similarly to a nanoflare storm. …
