Line Identification

As part of the laboratory astrophysics program at the electron beam ion traps of the Lawrence Livermore National Laboratory, L-shell X-ray emission of Fe and Ni ions have been studied extensively in the past decade. In this paper, we review these experimental efforts in line identification and wavelength surveys of Fe and Ni L-shell emission and resonance contributions to their intensities.

Strong Scaling

The QUDA library for optimized lattice quantum chromodynamics using GPUs, combined with a high-level application framework such as the Chroma software system, provides a powerful tool for computing quark propagators, a key step in current calculations of hadron spectroscopy, nuclear structure, and nuclear forces. In this contribution we discuss our experiences, including performance and strong scaling of the QUDA library and Chroma on the Edge Cluster at Lawrence Livermore National Laboratory and on various clusters at Jefferson Lab. We highlight some scientific successes and consider future directions for graphics processing units in lattice quantum chromodynamics calculations.

Introduction: Little is known about prehospital availability and use of medications to treat patients from hazardous materials (hazmat) medical emergencies. The aim of this study was to identify the availability and frequency of use of medications for patients in hazmat incidents by paramedics with advanced training to care for these patients.Methods: A prospectively validated survey was distributed to United States paramedics with advanced training in the medical management of patients from hazmat incidents who successfully completed a 16-hour Advanced Hazmat Life Support (AHLS) Provider Course from 1999 to 2017. The survey questioned hazmat medication availability, storage, and frequency of use. Hazmat medications were considered to have been used if administered anytime within the past 5 years. For analyses, medications were grouped into those with hazmat indications only and those with multiple indications.Results: The survey email was opened by 911 course participants and 784 of these completed the survey (86.1 percent). Of these 784 respondents, 279 (35.6 percent) reported carrying dedicated hazmat medication kits, ie, tox-boxes, and 505 (64.4 percent) did not carry tox-boxes. For those medications specifically for hazmat use, hydroxocobalamin was most commonly available, either within or not within a dedicated tox-box. Of the 784 respondents, 313 (39.9 percent) reported carrying hydroxocobalamin and 69 (8.8 percent) reported administering it within the past 5 years. For medications with multiple indications, availability and use varied: for example, of the 784 respondents, albuterol was available to 699 (89.2 percent) and used by 572 (73.0 percent), while calcium gluconate was available to 247 (31.5 percent) and used by 80 (10.2 percent) within the last 5 years.Conclusion: Paramedics with advanced training in the medical management of patients in hazmat incidents reported limited availability and use of medications to treat patients in hazmat incidents.
