Korean GP?? I don't remember that at all. Webber makes a very silly mistake towards the end of the wet race, goes wide, touches grass and spins, hitting another car and he is out. So I am thinking oh so Vettel will win this race. Nope, he has engine problem and can't finish it either.

Single spin exact gradients for the optimization of complex pulses and pulse sequences
The efficient computer optimization of magnetic resonance pulses and pulse sequences involves the calculation of a problem-adapted cost function as well as its gradients with respect to all controls applied. The gradients generally can be calculated as a finite difference approximation, as a GRAPE approximation, or as an exact function, e.g. by the use of the augmented matrix exponentiation, where the exact gradient should lead to best optimization convergence. However, calculation of exact gra…

ASKAP J144834-685644: a newly discovered long period radio transient detected from radio to X-rays
Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarised radio bursts with periods varying from a few minutes to a few hours. Fewer than a dozen LPTs have been detected so far, and their origin (source and emission mechanism) remains unclear. Here, we report the discovery of a 1.5 hr LPT, ASKAP J144834-685644, adding to the current sample of sources. ASKAP J144834-685644 is one of the very few LPTs that has been detected from X-rays to radio. It…

We have furthermore analysed the ratio of extreme decay branching into the first excited state of daughter nuclei with alpha or proton emission at relative kinetic energies where previous measurements are in disagreement with each other.

We study the relation between representations of certain infinite-dimensional Lie groups and those of the associated conformal nets. For a chiral conformal net extending the net generated by the vacuum representation of a loop group or diffeomorphism group of the circle, we show that any conformal net representation induces a positive-energy representation of the corresponding group. Consequently, we prove that any representation of such a conformal net is automatically diffeomorphism covariant…

A note on multiset reconstruction from sum and pairwise products
Ballantine, Beck, and Merca defined a map $\mathrm{pre}_2$, which sends an integer partition $λ= (λ_1, \dots, λ_{\ell})$ to the set $\{λ_iλ_j : 1 \leq i < j \leq \ell\}$ consisting of the pairwise products of parts of $λ$. The same three authors and Sagan conjectured that for each $n$, the map $\mathrm{pre}_2$ is injective on the set of integer partitions of $n$. In this note, we prove their conjecture.

SN 2019hnl: A Type IIP Supernova with a Partially Stripped, Low Mass Progenitor
We present optical photometry and spectroscopy of SN 2019hnl. Discovered within ~26 hr of explosion by the ATLAS survey, SN 2019hnl is a typical Type IIP supernova with a peak absolute V band magnitude of -16.7+-0.1 mag, a plateau length of ~107 days, and an early decline rate of 0.0086+-0.0006 mag (50 days)^-1. We use nebular spectroscopy and hydrodynamic modeling with the SNEC, MESA, and STELLA codes to infer that the progenitor of SN 2019hnl was a M_ZAMS ~ 11M_solar red supergiant which prod…
