Excessive sweat secreted from the skin often causes undesired adhesion wetted textiles and cold sensations. Traditional hydrophilic such as cotton can absorb but retain it. A hydrophobic/superhydrophilic Janus polyester/nitrocellulose textile embedded with a conical micropore array inner surface that achieve directional liquid transport (with an ultrahigh water capability of 1246%) maintain human body temperature (2-3 °C higher than textiles) is demonstrated. When hydrophobic polyester layer...

Abstract For the global oceans, characteristics of high‐resolution climate changes during last millennium remain uncertain because limited availability proxy data. This study reconstructs conditions using annually resolved coral records from South China Sea (SCS) to provide new insights into change over millennium. The results indicate that Medieval Climate Anomaly (MCA, AD 900–1300) was similar Current Warm Period (CWP, 1850‐present), which contradicts previous studies. warmth levels for...

Abstract The aim of this study was to investigate left ventricular (LV) global myocardial strain and LV involvement characteristics in patients with arrhythmogenic right dysplasia/cardiomyopathy (ARVD/C) evaluate their predictive value adverse cardiac events. Sixty consecutive ARVD/C a definite diagnosis who underwent CMR examination thirty-four healthy controls were enrolled retrospectively. images analyzed for the presence involvement. endpoint defined as composite sustained tachycardia or...

Abstract Major and trace elements, Sr Nd isotopes of bulk particles from the SCS‐NW SCS‐N‐03 traps were studied to provenance sinking in northern South China Sea (SCS). About 63% biogenic materials most lithogenic trap may be contributed resuspended sediments, more are collected winter than summer. The immobile‐element discrimination diagrams also indicate that are, a large degree, local seafloor SCS‐N SCS‐W have seasonal variations. ( 87 Sr/ 86 δ 88 Sr) significantly influenced by cannot...

Abstract The trace metal element zinc (Zn) participates in coral metabolic processes and therefore accumulates their skeletons. These are largely controlled by the changes of environment which they live, so Zn isotopic compositions (δ 66 Zn) skeletons may possibly serve as potential tracers for climate environmental changes. In this study, we first reported δ shallow‐water investigating with monthly resolution values skeleton a modern Porites 10AR2 from Great Barrier Reef Australia, bulk...

Rationale Carbon and oxygen isotopic compositions of individual minerals in calcite–dolomite mixtures could be measured using a selective acid extraction technique based on the different reaction rates calcite dolomite with phosphoric acid. However, poor accuracies are usually obtained when low content analyzed, which may result incorrect conclusions. To overcome this shortcoming, improvements needed accuracy precision content. Methods Calcite were analyzed under conditions GV Isoprime™ II...

Abstract Understanding the geochemical behavior of Mo isotopes in estuarine systems is essential for determining isotopic composition riverine inputs to ocean and assessing historical oxidation state Earth’s ancient oceans. However, extent mechanisms isotope fractionation during processes are not yet fully understood. This study systematically investigated seasonal spatial variations aqueous particulate δ 98 values within Pearl River Estuary (PRE). Our research found that aque. both summer...

Epoxy resin anticorrosion coating is widely used in grounding grid corrosion protection because of its wide range materials, good antiseptic effect and convenient processing. Based on the latest research progress, four kinds epoxy anticorrosive coatings are introduced, which structural modified coating, inorganic organic polyaniline / composite coating. In this paper, current progress base analyzed, prospected possible development direction anti-corrosion grid, provides a reference for...

Abstract Identifying the response of corals to anthropogenic ocean warming and acidification remains challenging, but is critical understanding coral resilience in a changing world. Here, we report composite records skeletal growth (1847–2014) nine Porites spp. colonies from open northern South China Sea (SCS), paired reconstructions sea surface temperature (SST) seawater pH (pH sw ) by examining Sr/Ca δ 11 B two cores. The demonstrate that SCS has experienced significant since 1960s with an...

Abstract Porites corals are valuable geological archives for reconstructing past sea surface temperature (SST) in tropical oceans. Their clumped isotope compositions (indicated by Δ 47 values) provide a potential proxy SST. The value coral usually departs from thermodynamic equilibrium due to vital effects. To explore the dependence of values corals, we determined δ 13 C, 18 O, and two modern South China Sea. Our results indicate no intercolony or intracolony biases on annual timescales....

Prompt and accurate diagnosis of acute ischemic stroke is critical to seek therapy. In traditional Chinese medicine (TCM) science, there a comprehensive system medical care stroke. Here we introduce two-level model for the analysis TCM syndrome Owing limitation sample size imbalance, focused on wind-phlegm collateral obstruction (Feng Tan Yu Zu Zheng). Firstly, Support-Vector-Machine- (SVM-) based diagnostic was set up through selection core symptoms. After pairwise undersampling, improved...

Abstract Climate change in the mid‐to‐late Holocene transition is very important for predicting future climate trends and understanding relationship between abrupt development of past human civilization. In this study, Sr/Ca ratios δ 18 O records with annual resolution extracted from four fossil corals that were growing during Middle Bronze Age Cold Epoch (MBACE) used to reconstruct sea surface temperature (SST) seawater (δ sw ) South China Sea (SCS) transition. The results indicate SCS...
