TL;DR: In this paper, the authors presented extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk, which was nearly identical in its observed properties to SN 2002cx, which has been called ''the most peculiar known type Ia supernova''.
Abstract: We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002cx, which has been called ``the most peculiar known type Ia supernova.'' Both supernovae exhibited high ionization SN 1991T-like pre-maximum spectra, yet low peak luminosities like SN 1991bg. The spectra reveal that SN 2005hk, like SN 2002cx, exhibited expansion velocities that were roughly half those of typical type Ia supernovae. The R and I light curves of both supernovae were also peculiar in not displaying the secondary maximum observed for normal type Ia supernovae. Our YJH photometry of SN 2005hk reveals the same peculiarity in the near-infrared. By combining our optical and near-infrared photometry of SN 2005hk with published ultraviolet light curves obtained with the Swift satellite, we are able to construct a bolometric light curve from ~10 days before to ~60 days after B maximum. The shape and unusually low peak luminosity of this light curve, plus the low expansion velocities and absence of a secondary maximum at red and near-infrared wavelengths, are all in reasonable agreement with model calculations of a 3D deflagration which produces ~0.25 M_sun of 56Ni.

TL;DR: Comparative degradation of azo dyes by 520 kHz ultrasonic irradiation and its combinations with ozone and/or ultraviolet light (UV) was investigated using a probe dye and the overall degradation process was most rapid under simultaneous operation of the three in the presence of a continuous flow of a gas mixture made of argon and oxygen.

TL;DR: It is demonstrated that in contrast to cellular stresses previously examined, hydrogen peroxide exposure affects Cdc25C but not C DC25A levels, and that oxidative stress may induce cell cycle arrest in part through the degradation of CDC25C.

TL;DR: A previously identified tumor-associated germline mutation in BARD1 (Gln564His) reduced binding to CstF and abrogated inhibition of polyadenylation, indicating a link between mRNA 3' processing and DNA repair and tumor suppression.
