Search for the bb ¯ decay of the Standard Model Higgs boson in associated (W/Z)H production with the ATLAS detector

Abstract: A search for the b (b) over bar decay of the Standard Model Higgs boson is performed with the ATLAS experiment using the full dataset recorded at the LHC in Run 1. The integrated luminosities used are 4.7 and 20.3 fb(-1) from pp collisions at root s = 7 and 8 TeV, respectively. The processes considered are associated (WIZ)H production, where W -> e nu/mu nu, Z -> ee/mu mu, and Z -> nu nu. The observed (expected) deviation from the backgroundonly hypothesis corresponds to a significance of 1.4 (2.6) standard deviations and the ratio of the measured signal yield to the Standard Model expectation is found to be mu = 0.52 +/- 0.32 (stat.) +/- 0.24 (syst.) for a Higgs boson mass of 125.36 GeV. The analysis procedure is validated by a measurement of the yield of (W/Z)Z production with Z -> b (b) over bar in the same final states as for the Higgs boson search, from which the ratio of the observed signal yield to the Standard Model expectation is found to be 0.74 +/- 0.09 (stat.) +/- 0.14 (syst.).

Examining Pediatric Resuscitation Education Using Simulation and Scripted Debriefing: A Multicenter Randomized Trial

Abstract: Importance Resuscitation training programs use simulation and debriefing as an educational modality with limited standardization of debriefing format and content. Our study attempted to address this issue by using a debriefing script to standardize debriefings. Objective To determine whether use of a scripted debriefing by novice instructors and/or simulator physical realism affects knowledge and performance in simulated cardiopulmonary arrests. Design Prospective, randomized, factorial study design. Setting The study was conducted from 2008 to 2011 at 14 Examining Pediatric Resuscitation Education Using Simulation and Scripted Debriefing (EXPRESS) network simulation programs. Interprofessional health care teams participated in 2 simulated cardiopulmonary arrests, before and after debriefing. Participants We randomized 97 participants (23 teams) to nonscripted low-realism; 93 participants (22 teams) to scripted low-realism; 103 participants (23 teams) to nonscripted high-realism; and 94 participants (22 teams) to scripted high-realism groups. Intervention Participants were randomized to 1 of 4 arms: permutations of scripted vs nonscripted debriefing and high-realism vs low-realism simulators. Main Outcomes and Measures Percentage difference (0%-100%) in multiple choice question (MCQ) test (individual scores), Behavioral Assessment Tool (BAT) (team leader performance), and the Clinical Performance Tool (CPT) (team performance) scores postintervention vs preintervention comparison (PPC). Results There was no significant difference at baseline in nonscripted vs scripted groups for MCQ (P = .87), BAT (P = .99), and CPT (P = .95) scores. Scripted debriefing showed greater improvement in knowledge (mean [95% CI] MCQ-PPC, 5.3% [4.1%-6.5%] vs 3.6% [2.3%-4.7%]; P = .04) and team leader behavioral performance (median [interquartile range (IQR)] BAT-PPC, 16% [7.4%-28.5%] vs 8% [0.2%-31.6%]; P = .03). Their improvement in clinical performance during simulated cardiopulmonary arrests was not significantly different (median [IQR] CPT-PPC, 7.9% [4.8%-15.1%] vs 6.7% [2.8%-12.7%], P = .18). Level of physical realism of the simulator had no independent effect on these outcomes. Conclusions and Relevance The use of a standardized script by novice instructors to facilitate team debriefings improves acquisition of knowledge and team leader behavioral performance during subsequent simulated cardiopulmonary arrests. Implementation of debriefing scripts in resuscitation courses may help to improve learning outcomes and standardize delivery of debriefing, particularly for novice instructors.

Experimental Studies on Ettringite-Induced Heaving in Soils

Abstract: Sulfate-induced heaving in soils is primarily attributed to ettringite formation from the reactions between calcium of a lime or cement stabilizer, reactive alumina in soils, and sulfates in soils. Ettringite formation and subsequent heaving in soils are complex topics that are not well understood. This research is an attempt to advance the state of the knowledge on these topics. Ettringite was successfully synthesized in the laboratory by simulating conditions close to those in chemically treated sulfate-bearing soils. Soils spiked and compacted with the synthesized ettringite did not undergo heaving in one-dimensional free swell tests. However, heaving was observed when ettringite was formed inside the lime-treated soil specimen by including ionic reactions. Mineralogical studies including x-ray diffraction and scanning electron microscope studies were used to evaluate the presence of ettringite. Experimental investigations showed that the ettringite or sulfate-induced heaving was higher in clays than in sands under similar chemistry and environmental conditions. This is attributed to the void sizes of soil types and crystalline ettringite formation in the voids. Also, the effects of soil type, lime and sulfate amounts on this type of heaving, and hypothesized threshold levels of chemical ions to form ettringite mineral in treated soils, are addressed.
