Flashes of Insight

Flashes of noncommutativity

Noncommutativity lays hidden in the proofs of classical dynamics. Modern frameworks can be used to bring it to light: *-products, groupoids, q-deformed calculus, etc.

Optical flashes and GeV-TeV flashes from gamma-ray bursts

The optical flash caught by ROTSE in GRB 990123 overlaps with the MeV radiation front. This overlapping has two implications: (1) If the flash has a synchrotron origin, the electrons emitting optical radiation must also create a GeV-TeV flash by inverse Compton scattering of the MeV photons. The high-energy flash can be much stronger than its optical counterpart and comparable with the main MeV...

Flashes on Hidradenitis Suppurativa

Protons Trigger Mitochondrial Flashes.

Emerging evidence indicates that mitochondrial flashes (mitoflashes) are highly conserved elemental mitochondrial signaling events. However, which signal controls their ignition and how they are integrated with other mitochondrial signals and functions remain elusive. In this study, we aimed to further delineate the signal components of the mitoflash and determine the mitoflash trigger mechanis...

Optical Flashes Preceding Grbs

Only one optical flash associated with a gamma-ray burst has been detected so far by ROTSE. There are also upper limits obtained by several groups for several bursts. Recent model calculations indicate a possibility that optical flash may precede the GRB. Such flashes are undetectable in the currently popular observing mode, with optical instruments responding to GRB triggers. There is a need t...
