AI preference prediction beyond substituted judgement
Tracking patient preferences is vital to medical decision-making, but evidence suggests that the standard method for tracking the preferences of incapacitated or incompetent patients (ie, surrogates) is inaccurate. Recent proposals suggest that artificial intelligence preference predictors (AIPPs) can improve preference tracking for these patients, but have faced significant objections. While many of these objections depend on unsettled empirical…
Potential geochemical evidence of Porites corals responding to coral bleaching in the 20th century in the Nansha Islands, southern South China Sea
Records of sea-level highstand over the Meghalayan age/late Holocene from uranium-series ages of beachrock in Weizhou Island, northern South China Sea
Beachrock is considered a good archive for past sea-levels because of its unique formation position (intertidal zone). To evaluate sea-level history in the northern South China Sea, three well-preserved beachrock outcrops (Beigang, Gongshanbei, and Hengling) at Weizhou Island, northern South China Sea were selected to examine their relative elevation, sedimentological, mineralogical, and geochemical characteristics. Acropora branches with well-pr…
Coral δ18O-based reconstruction of El Niño-Southern Oscillation from the northern south China sea since 1851 AD
First discovery of a bone handaxe in China
Human‐caused stratigraphic mixing of a coastal Hawaiian midden during prehistory
Archaeologists rely on the spatial and temporal distribution of artifacts and other site‐based materials to understand the stratigraphic integrity of the matrix in which remains are embedded. Although they are aware of taphonomic and site formation processes that can cause post‐depositional movement of objects, misinterpretation can occur. We used high‐precision 230 Th dating of branch corals found throughout cultural layers of a coastal Hawaiian…
Microatoll record for large century-scale sea-level fluctuations in the mid-Holocene
Coral microatolls have been long used as precise indicators of past sea level, but their use for precise definition of detailed sea-level fluctuations is still rare. Here we report twelve high-precision thermal ionization mass spectrometric 230 Th ages for twelve rims of five mid-Holocene microatolls from an emerged reef terrace at Leizhou Peninsula, northern South China Sea. This is a tectonically stable area, enabling us to reconstruct both the…
Paleoprecipitation record from coral Sr/Ca and δ18O during the mid Holocene in the northern South China Sea
Coupled high-resolution Sr/Ca and δ 18 O records of a modern and a mid-Holocene coral from Sanya in the southern Hainan Island, northern South China Sea (SCS), were reported and the residual δ 18 O (Δδ 18 O) were calculated to indicate precipitation change in this region. Unlike other paleoclimate studies, this study focused on changes of precipitation time rather than precipitation amount. As negative Δδ 18 O peaks in coral generally correspond …
U-series dates of Great Barrier Reef corals suggest at least +0.7 m sea level ~7000 years ago
Strong evidence from field observation and high-precision TIMS U-series dating of exposed in situ massive corals and exposed microatolls on Magnetic Island, Great Barrier Reef, indicates that the relative sea level was at least 0.7 m higher than present ~7000 calendar years (cal yr) ago, and culminated to at least ~1.6 m higher than present ~5800 cal yr ago. The present sea level was probably first reached around 7300—7100 cal yr ago. Together wi…
