Abstract The Intertropical Convergence Zone (ITCZ) encompasses the heaviest rain belt on Earth. Few direct long-term records, especially in Pacific, limit our understanding of natural variability for predicting future ITCZ migration. Here we present a tropical precipitation record from Southern Hemisphere covering past 282,000 years, inferred marine sedimentary sequence collected off eastern coast Papua New Guinea. Unlike precession paradigm expressed its East Asian counterpart, shows that...
Abstract Monomethylmercury (MMHg) is a potent toxin that bioaccumulates and magnifies in marine food webs. Recent studies show abundant methylated Hg deep oceans (>1000 m), yet its origin remains uncertain. Here we measured isotope compositions fauna surface sediments from the Mariana Trench. The trench at 7000–11000 m depth all have substantially positive mass-independent fractionation of odd isotopes (odd-MIF), which can be generated only photic zone via MMHg photo-degradation. Given...
The strain-stiffening and self-healing capabilities of biological tissues enable them to preserve the structures functions from deformation damage. However, biodegradable hydrogel materials with both these biomimetic characteristics have not been explored. Here, a series strain-stiffened, hydrogels are developed through dynamic imine crosslinking semiflexible O-carboxymethyl chitosan (main chain) flexible dibenzaldehyde-terminated telechelic poly(ethylene glycol) (crosslinker). can be...
Modern acidification by the uptake of anthropogenic CO2 can profoundly affect physiology marine organisms and structure ocean ecosystems. Centennial-scale global regional influences remain largely unknown due to limited instrumental pH records. Here we present coral boron isotope-inferred records for two periods from South China Sea: AD 1048-1079 1838-2001. There are no significant differences between first period at Medieval Warm Period 1830-1870. However, find anomalous unprecedented...
Abstract A large and sudden increase in radiocarbon ( 14 C) around AD 773 are documented coral skeletons from the South China Sea. The C increased by ~ 15‰ during winter remain elevated for more than 4 months, then dropped down within two forming a spike of 45‰ high late spring, followed smaller spikes. anomalies coincide with an historic comet collision Earth's atmosphere on 17 January 773. Comas known to have percent-levels nitrogen weight exposed cosmic radiation space. Hence they may be...
Deep oceans receive mercury (Hg) from upper oceans, sediment diagenesis, and submarine volcanism; meanwhile, sinking particles shuttle Hg to marine sediments. Recent studies showed that in the trench fauna mostly originated monomethylmercury (MMHg) of photosynthetic food webs. Yet, sources deep-sea chemosynthetic webs are still uncertain. Here, we report concentrations stable isotopic compositions indigenous biota living at hydrothermal fields Indian Ocean Ridge a cold seep South China Sea...
Abstract The driving forces, kill and recovery mechanisms for the end-Permian mass extinction (EPME), largest Phanerozoic biological crisis, are under debate. Sedimentary records of mercury enrichment isotopes have suggested impact volcanism on EPME, yet causes isotope variations remain controversial. Here, we model across EPME to quantitatively assess effects volcanism, terrestrial erosion photic zone euxinia (PZE, toxic, sulfide-rich conditions). Our numerical shows that while large-scale...
With the increasing performance requirements of electronic devices for PCB, especially voltage level, electrical safety and structural stability printed circuit boards (PCBs) are also increasing. This study focuses on improving insulation capability PCB through drilling technology, establishes a dual-pad analysis system, utilizes finite element to evaluate effect different hole shapes, quantities, positions system improvement based indicators such as creepage distance electric field...
Joint mobilization, as a commonly used technique in the field of rehabilitation therapy, has significant effect on improving joint dysfunction and holds an important position. This article aims to comprehensively elaborate principles mobilization deeply explore its clinical applications various diseases, including temporomandibular joints, shoulder knee cervical lumbar injuries, providing valuable evidence for clinicians carry out related treatment work.
Abstract The magnetic core is the of fluxgate current sensor. In order to better analyze effect field bias on hysteresis curve caused by measurement probe, a DC correction carried out basis J-A model, and numerical simulations are performed calculate model. improve saturation agglomeration performance air-gap cores, four kinds opening closing structures designed, which provide an optimization method for design actual sensor cores. detection technology has variety products at home abroad, but...
Pollutant emissions from coal fires have caused serious concerns in major coal-producing countries. Great efforts been devoted to suppressing them China, notably at the notorious Wuda Coalfield Inner Mongolia. Recent surveys revealed that while this coalfield nearly extinguished near surface, they persist underground. However, impacts of Hg volatilized underground remain unclear. Here, we measured concentrations and isotope compositions atmospheric both gaseous particulate phases an urban...
Dyslipidemia and abnormal cholesterol metabolism are closely related to coronary artery calcification (CAC) also critical factors in cardiovascular disease death. In recent years, the atherogenic index of plasma (AIP) has been widely used evaluate vascular sclerosis. This study aimed investigate potential association AIP between CAC major adverse events (MACEs).
The contemporary mercury (Hg) cycle in the world's oceans has been greatly affected by human activities. However, we are still lacking reliable, long-term, and continuous records of Hg seawater. Here, report for first time on using annually banded Porites coral skeletons from northern South China Sea (SCS) as an archive recording changes seawater dissolved spanning past two centuries. We developed a combustion-trapping method to preconcentrate ultratrace concentrations aragonitic highly...
