Image patch analysis of sunspots and active regions

Journal of Space Weather and Space Climate, 2016
Context. The flare productivity of an active region is observed to be related to its spatial complexity. Mount Wilson or McIntosh sunspot classifications measure such complexity but in a categorical way, and may therefore not use all the information ...

Where Do Solar Storms Prefer to Originate From: Hemispheric and Longitudinal Patterns in Solar Cycles 23 and 24

The Astrophysical Journal
Using synoptic maps, we analyzed the relationship between active longitudes, the most populated longitudes of energetic flares, the distribution of magnetically complex active regions, and the preferred locations of those that produced the largest flares.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Potential Height-dependent Magnetic Signatures Associated with the Eruptive State of Magnetically Complex Active Regions and Their Relationship to Active Longitudes

The Astrophysical Journal
The mechanism by which some magnetically complex active regions evolve toward highly eruptive states while others remain relatively quiet remains an open question under active debate.

Buildings Stability Revaluation in Seismically Active Regions

MATEC Web of Conferences, 2017
In 2015 the maps of seismic zoning on the territory of Russia were detailed according to new general standards (ОSR-2015). Compared to the previous data, the number of seismically dangerous areas has the tendency to increase.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Magnetic Reconnection between a Solar Jet and a Filament Channel

The Astrophysical Journal
The solar corona is highly structured by bunches of magnetic field lines forming either loops, or twisted flux ropes representing prominences/filaments, or very dynamic structures such as jets.
