Background: Surgeons may hesitate to apply external ring fixators (ERFs) due to perceived high clinical burden. This study aims to quantify the relative demand of ERFs compared with other common foot and ankle procedures. Understanding the demand of ERFs can provide insights into postoperative experiences, potentially decreasing intimidation of their use.
View Article and Find Full Text PDFAstronomers have found more than a dozen planets transiting stars that are 10-40 million years old, but younger transiting planets have remained elusive. The lack of such discoveries may be because planets have not fully formed at this age or because our view is blocked by the protoplanetary disk. However, we now know that many outer disks are warped or broken; provided the inner disk is depleted, transiting planets may thus be visible.
View Article and Find Full Text PDFIntroduction: Twenty percent of medical school faculty are 60 years or older. These senior-career academic faculty often find a paucity of support for decision-making about late-career transitions.
Methods: To help fill this professional development gap, we developed and tested an interactive workshop to facilitate deliberation and discussion among mid- and late-career faculty in various stages of career transition planning.
Article Synopsis
- - The Daya Bay experiment has successfully measured the oscillation amplitude and frequency of reactor antineutrinos over nearly 2,000 days of data, finding significant results about their behavior.
- - They observed over 3.6 million signal candidates using improved selection and calibration methods, leading to a measurement of sin²2θ₁₃ = 0.0759 with a precision that indicates how antineutrinos change states.
- - Combining results from different detection methods at Daya Bay, the overall measurement of sin²2θ₁₃ increased precision to 0.0833±0.0022, representing an 8% improvement in understanding these neutrino properties.
Article Synopsis
- Anthropogenic activities release around 2,000 metric tons of mercury annually, affecting remote ecosystems and leading to inconsistencies in reported emissions and atmospheric concentrations in the Northern Hemisphere.
- Despite reported increases in mercury emissions over the past 30 years, data analysis shows a declining trend in atmospheric mercury levels, indicating that actual emissions must have decreased significantly, contradicting existing inventories.
- By using statistical modeling of data from 51 monitoring stations, the study highlights a decline in mercury concentrations from 2005 to 2020, suggesting that reductions in local emissions, rather than reemissions of legacy mercury, are primarily responsible for these trends and raising questions about the reliability of current emission inventories.
