Unusual open-system behaviour revealed by LA-MC-ICP-MS U–Th dating of coral and coralline algae bio-carbonates by Condomines, Michel, Bruguier, Olivier, Hajji, Inès, Zaara-Ben Mosbah, Chedia

“…This paper presents new U–Th ages obtained by LA-MC-CP-MS (laser ablation - multi-collector - inductively coupled plasma - mass spectrometry) on coral samples from a sedimentary core of the Tunis lagoon. The ages and calculated ($\mbox {}^{234}$U/$\mbox {}^{238}$U)$_{0}$ initial ratios, similar to the seawater value for most corals demonstrate that they behaved as closed systems, or with only a very limited loss of $\mbox {}^{234}$U and $\mbox {}^{230}$Th. …”

Exploring canyons beneath Devon Ice Cap for sub-glacial drainage using radar and thermodynamic modeling by Chris Pierce, Mark Skidmore, Lucas Beem, Don Blankenship, Ed Adams, Christopher Gerekos

“…Our simulated results indicated a 10 m wide canal-like water feature is unlikely along the canyon floor, but smaller features may be difficult to detect via RES. We calculated basal temperature profiles using a 2D finite difference method and found the floor may be up to 18°C warmer than the terraces. …”

Predicted quality benefits of achievable performance benchmarks of chronic heart failure care in China: results from a nationwide observational study by Xi Li, Chao Wang, Jingkun Li, Yupeng Wang, Xiaoqiang Bao, Meina Liu, Qiuju Zhang, Chang Yin, Xudong Ma

“…Objectives This study aimed to set a data-driven achievable performance benchmark, explore the process–outcome association and speculate about the net gain in quality improvement with benchmarking.Design Observational study.Setting Patient survey conducted at 466 secondary and tertiary hospitals across 31 provinces, autonomous regions and municipalities in China.Participants 183 334 patients diagnosed with chronic heart failure (CHF) who were treated at 466 Chinese hospitals from January 2011 through May 2017.Primary independent variables Hospital process composite performance (HPCP).Secondary independent variables Patient-level and hospital-level characteristics.Primary outcome measure Patients getting better or recovered after treatment, in-hospital mortality, length of hospital stay (LOS) and medical cost.Methods HPCP was calculated using denominator-based weights. Mixed random-intercept models were used to evaluate the contributions of HPCP on patient outcomes and to speculate quality improvement after adjusting HPCP to benchmark level.Results When all hospitals were to operate at the benchmark level, the proportion of patients getting better or recovered after treatment would increase in most hospitals, particularly those with low baseline rates. …”
