From SaltyBurger https://twitter.com/SaltyBurger on Twitter: 5 years into the project and we are proud to present our idea of the next generation track reconstruction toolkit for upcoming exciting times and R&D. This builds upon the experience & includes the work of many especially (but !only) from @ATLASexperiment https://arxiv.org/abs/2106.13593 https://twitter.com/SaltyBurger/status/1409411743445655552/photo/1 https://chirp.cooleysekula.net/attachment/72353

  A Common Tracking Software Project
  
  from arXiv.org
  
  The reconstruction of the trajectories of charged particles, or track reconstruction, is a key computational challenge for particle and nuclear physics experiments. While the tuning of track reconstruction algorithms can depend strongly on details of the detector geometry, the algorithms currently in use by experiments share many common features. At the same time, the intense environment of the High-Luminosity LHC accelerator and other future experiments is expected to put even greater computational stress on track reconstruction software, motivating the development of more performant algorithms. We present here A Common Tracking Software (ACTS) toolkit, which draws on the experience with track reconstruction algorithms in the ATLAS experiment and presents them in an experiment-independent and framework-independent toolkit. It provides a set of high-level track reconstruction tools which are agnostic to the details of the detection technologies and magnetic field configuration and tested for strict thread-safety to support multi-threaded event processing. We discuss the conceptual design and technical implementation of ACTS, selected applications and performance of ACTS, and the lessons learned.

From keratx https://twitter.com/keratx on Twitter: The Delta variant of the coronavirus is spreading so quickly, it's likely the strain will become predominant in the U.S. within weeks. The most contagious yet among those not yet vaccinated, it already accounts for at least 14% of all new infections. https://www.keranews.org/health-wellness/2021-06-22/delta-variant-of-the-coronavirus-could-dominate-in-u-s-within-weeks https://twitter.com/keratx/status/1407438256527003653/photo/1 https://chirp.cooleysekula.net/attachment/72291

  Annual modulation results from three-year exposure of ANAIS-112
  
  from arXiv.org
  
  ANAIS (Annual modulation with NaI Scintillators) is a dark matter direct detection experiment consisting of 112.5 kg of NaI(Tl) detectors in operation at the Canfranc Underground Laboratory (LSC), in Spain, since August 2017. ANAIS' goal is to confirm or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate having all the features expected for the signal induced by dark matter particles in a standard galactic halo. This modulation, observed for about 20 years, is in strong tension with the negative results of other very sensitive experiments, but a model-independent comparison is still lacking. By using the same target material, NaI(Tl), such comparison is more direct and almost independent on dark matter particle and halo models. Here, we present the annual modulation analysis corresponding to three years of ANAIS data (for an effective exposure of 313.95 kg$\times$y), applying a blind procedure which updates that developed for the 1.5 years analysis, and later applied to 2 years. The analysis also improves the background modelling in the fitting of the region of interest rates. We obtain for the best fit in the [1-6] keV ([2-6] keV) energy region a modulation amplitude of -0.0034$\pm$0.0042 cpd/kg/keV (0.0003$\pm$0.0037 cpd/kg/keV), supporting the absence of modulation in our data, and incompatible with DAMA/LIBRA result at 3.3 (2.6) $σ$, for a sensitivity of 2.5 (2.7) $σ$. Moreover, we include two complementary analyses: a phase-free annual modulation search and the exploration of the possible presence of a periodic signal at other frequencies. Finally, we carry out several consistency checks of our result, and we update the ANAIS-112 projected sensitivity for the scheduled 5 years of operation.

@clacke Medical science here is paid for with tax dollars and then the treatments and care are sold back to the taxpayer at high prices through a private system. AND states have sold the information to various entities—Texas sold theirs to the Pentagon, for some reason. So, it's a hellscape herre.
