Search for gravitational waves associated with gamma-ray bursts detected by Fermi and Swift during the LIGO–Virgo run O3b

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC–2020 March 27 17:00 UTC). We conduct two independent searches: a generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence for subthreshold gravitational-wave signals associated with this GRB ensemble either. We use several source types and signal morphologies during the searches, resulting in lower bounds on the estimated distance to each GRB. Finally, we constrain the population of low-luminosity short GRBs using results from the first to the third observing runs of Advanced LIGO and Advanced Virgo. The resulting population is in accordance with the local binary neutron star merger rate

Kind met buikpijn en rectaal bloedverlies

Van Leeuwen CD, Holtman GA, Kranenberg JJ. A girl with abdominal pain and rectal bleeding. Huisarts Wet 2015;58(1):42-4. Enterobius vermicularis, or threadworm, is not often considered in the differential diagnosis of abdominal pain and blood in faeces, but it is advisable not to ignore this diagnosis. While E. vermicularis infection is usually not harmful, in rare cases invasion of the intestinal mucosa can lead to more severe inflammatory signs, such as rectal bleeding. It is not clear under which conditions this common intestinal parasite invades the intestinal mucosa, but it seems that it makes its entry through existing injury or lesions. E. vermicularis infection can easily be treated, and preferably the entire family should be treated, to prevent re-infection.</p
