Search for Dark-Matter-Nucleon Interactions via Migdal Effect with DarkSide-50.

Dark matter elastic scattering off nuclei can result in the excitation and ionization of the recoiling atom through the so-called Migdal effect. The energy deposition from the ionization electron adds to the energy deposited by the recoiling nuclear system and allows for the detection of interactions of sub-GeV/c^{2} mass dark matter. We present new constraints for sub-GeV/c^{2} dark matter using the dual-phase liquid argon time projection chamber of the DarkSide-50 experiment with an exposure of (12 306±184)  kg d.

Hospitalizations for pelvic inflammatory disease in Texas. A population-based analysis.

Objective: To calculate pelvic inflammatory disease (PID) hospitalization rates for Texas and identify risk factors for prolonged length of stay (PLOS) among women hospitalized for PID throughout Texas and discharged during a 2-year period.

Study Design: A cross-sectional study of 6,421 women discharged from Texas hospitals in 2004 and 2005 with a diagnosis of PID was conducted. Data for 2004 and 2005 were obtained from the Texas Department of State Health Services.

Regional coronary blood flow in canine hemorrhagic shock.

This study examined circumferential, apex-to-base, and transmural distribution of coronary blood flow at rest and in hemorrhagic shock in a canine model. In addition, animals subjected to identical anesthesia and instrumentation were not hemorrhaged and served as controls. Regional coronary blood flow was measured by the radioactive microsphere technique, using 15-microns diameter microspheres in both control and shocked dogs.
