Advanced Science, EarlyView.The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

Gamma-ray bursts and gamma-ray blazars
AIP Conference Proceedings, 1994We propose that cosmological gamma‐ray bursts are produced when modestly sized black holes tidally disrupt stars, energizing relativistically outflowing jets and producing bursts for favorably oriented observers. The crucial test of this model is the detection of soft x‐ray flares with durations of ∼102 s and fluences ∼10−10−10−6 ergs cm−2 at rates of ...

The distribution of γ‐ray bursts as observed by BATSE rules out the galactic disk origin, and it is consistent with the cosmological origin. Much work is currently done to reconcile galactic halo distribution with the absence of dipole and quadrupole moments in the positions of BATSE bursts. A relativistic expansion of the source is implied by both the

AIP Conference Proceedings, 1983
The time histories, size spectrum, spatial distribution, and repetition rates of gamma ray bursts are reviewed briefly. Evidence for a neutron star origin for gamma ray bursts may be found in many of these aspects of bursters. New results from optical searches are described.

We summarize the observed features of γ-ray bursts, with particular emphasis on the cyclotron lines seen in their spectra. We then discuss the theory of cyclotron resonant scattering, and compare the theoretical and observed line spectra. Finally, we mention some implications.

Abstract The potential value of investigation of the γ-ray content of cosmic radiation has long been recognized, but evaluation of measurements made with high-flying balloons is difficult because of the generation of secondary γ-rays in the atmosphere above the detector.

OBSERVATIONS OF THE HIGHEST ENERGY GAMMA-RAYS FROM GAMMA-RAY BURSTS
The Ninth Marcel Grossmann Meeting, 2001EGRET has extended the highest energy observations of gamma-ray bursts to GeV gamma rays. Such high energies imply the fireball that is radiating the gamma-rays has a bulk Lorentz factor of several hundred. However, EGRET only detected a few gamma-ray bursts. GLAST will likely detect several hundred bursts and may extend the maximum energy to a few 100

Abstract The observational status of gamma-ray astronomy in the TeV energy range is rapidly changing and is reviewed (1987) with emphasis on the limitations of the present observations. It is apparent that gamma-ray detection techniques must be improved and some methods by which this can be achieved are outlined.
