Psoriasis is a common inflammatory disease of especially high recurrence rate (90%) which suffered by approximately 3% the world population. The overexpression reactive oxygen species (ROS) plays critical role in psoriasis progress. Here we show that biomimetic iron single-atom catalysts (FeN4O2-SACs) with broad-spectrum ROS scavenging capability can be used for treatment and relapse prevention via related gene restoration. FeN4O2-SACs demonstrate attractive multiple enzyme-mimicking...
Atopic dermatitis (AD) is a prevalent chronic inflammatory skin disease that carries significant global economic burden. Elevated levels of reactive oxygen species (ROS) have been recognized as contributing to AD exacerbation, making them potential therapeutic target for treatment. Here, we introduce dual-site biomimetic copper/zinc metal–organic framework (Cu/Zn-MOF) featuring four types enzyme-like activities treatment via suppressing the Fcγ receptor (FcγR)-mediated phagocytosis signal by...
Abstract The cavity-based X-ray free-electron laser (XFEL) has promise in producing fully coherent pulses with a bandwidth of few meV and very stable intensity, whereas the currently existing self-amplified spontaneous emission (SASE) XFEL is capable generating ultra-short chaotic spectra. In general, can provide spectral brightness three orders magnitude higher than that SASE mode, thereby opening new door for cutting-edge scientific research. With development superconducting MHz...
Abstract The current single-atom catalysts (SACs) for medicine still suffer from the limited active site density. Here, we develop a synthetic method capable of increasing both metal loading and mass-specific activity SACs by exchanging zinc with iron. constructed iron (h 3 -FNC) high 6.27 wt% an optimized adjacent Fe distance ~ 4 Å exhibit excellent oxidase-like catalytic performance without significant decay after being stored six months promising antibacterial effects. Attractively,...
Both radar and optical signals are sensitive to the change of surface soil moisture (SSM) roughness properties (such as root mean squared height- RMSH), accuracy retrieved SSM from single remote sensing data is influenced by spatiotemporal roughness. Here, we attempt explore a method simultaneously estimate RMSH bare combining data, so weaken effect on inversion results. To achieve this goal, two satellite synchronous ground experiments were carried out, collecting 88 sampling plots each...
High‐temperature piezoelectric (1− x )BiScO 3 − PbTiO ceramics with composition ( =0.62, 0.63, 0.64, and 0.65) near the morphotropic phase boundary were fabricated. A thermal depoling experiment was used to investigate stability of polarization at temperature range from 200° 460°C. The results indicated that samples rhombohedral began depole when higher than 300°C, while a tetragonal showed good resistance up 440°C, close their Curie temperature.
Excessive inflammation associated with the uncontrolled release of proinflammatory cytokines is main cause death from influenza virus infection. Previous studies have indicated that inhibition interferon gamma-induced protein 10 (IP-10), interleukin-8 (IL-8), monocyte chemoattractant 1 (MCP-1), or their cognate receptors has beneficial effects. Here, by using monocytic U937 cells capable secreting three important during A infection, we measured inhibitory activities on production six...
The Shanghai soft X-ray Free-Electron Laser facility (SXFEL), which is the first FEL in China, being constructed two phases: test (SXFEL-TF) and user (SXFEL-UF). was initiated 2006 funded 2014. commissioning of finished 2020. 2016 to upgrade accelerator energy build undulator lines with five experimental end-stations. output photon will cover whole water window range. This paper presents an overview SXFEL facility, including considerations upgrade, layout design, construction status,...
Abstract This paper first applies a prediction model based on self‐attention memory ConvLSTM (SAM‐ConvLSTM) to predict the global ionospheric total electron content (TEC) maps with up 1 day of lead time. We choose TEC released by Center for Orbit Determination in Europe (CODE) as training data set covering period from 1999 2022. Besides that, we put several space environment additional multivariate‐features into framework enhance its forecasting ability. In order confirm efficiency proposed...
Recently, a new family of piezoelectric perovskite materials based on the solid solution (1− x )BiScO 3 – PbTiO was developed. This system found to have Curie temperature higher than 450°C and excellent properties near MPB composition. Niobium, as donor dopant in Pb(Zr,Ti)O other lead‐based materials, has commonly been used increase electrical resistivity, dielectric, properties. In current work, effect niobium substitution BS–PT reported. The results additions showed no large enhancement...
Abstract Atopic dermatitis (AD) is one of the most common allergic skin disorders affecting over 230 million people worldwide, while safe and efficient therapeutic options for AD are currently rarely available. Reactive oxygen species (ROS) accumulation plays a key role in AD's disease progression. Therefore, novel single‐atom catalyst designed with isolated Cu 1 ‐N 4 sites anchored on carbon support (Cu ISAC), featuring triple antioxidant enzyme‐mimicking activities, cascade catalytic...
This study investigates the impact of East Asian–western North Pacific (EAWNP) intra‐seasonal oscillation (ISO) on tropical cyclone (TC) genesis over South China Sea (SCS) and western (WNP). The result indicates that 20–70‐day (EAWNP‐ISO1) mainly modulates frequency TC genesis, while 10–20‐day quasi‐biweekly (EAWNP‐ISO2) usually influences location. impacts ISO are not only individual but also variation activity. In order to better monitor predict we group intensity into three categories...
Abstract The natural abundance of larval fish four carp species has been affected adversely by the Three Gorges Reservoir in Yangtze River. One methods to conserve is regulate hydrology regimes keep them optimal for spawning. Thirty‐two hydrologic indicators (HIs) associated with regime spawning sites at Jianli reach were analyzed range variability approach. Outputs correlated a genetic programming approach explore relationship between and abundance. Results showed that rate rise discharge...
Abstract In this work, the occurrence probability of extreme geomagnetic storms is estimated by applying value theory to activity Aa index. The index has 172 years observation time span, which much longer than other indices, and thus more suitable for analysis rarely occurred storms. We use two newly developed methods, block maxima method peak over threshold, find that storm happened in March 1989 may happen once per century. This result implies we should pay attention such can cause space...
Abstract Aurora provides an essential diagnostic to spatial and temporal variations of terrestrial space environment is also important proxy solar geomagnetic activities. Contemporary auroral observations have just continued for more than half a century. Visual phenomena recorded in historical books provide key clues understand the activities long history prior modern era. In this study, we compiled new catalog from ancient Korean books, including 2013 records with day‐level resolution 1012...
Multicellular magnetotactic prokaryotes (MMPs) are a unique group of bacteria that composed 10-100 individual cells and show coordinated swimming along magnetic field lines. MMPs produce nanometer-sized magnetite (Fe3O4) and/or greigite (Fe3S4) crystals-termed magnetosomes. Two types magnetosome gene cluster (MGC) regulate biomineralization have been found. Here, we describe dominant spherical MMP (sMMP) species collected from the intertidal sediments Jinsha Bay, in South China Sea. The...
Abstract The presence of grand minima, characterized by significantly reduced solar and stellar activity, brings a challenge to the understanding dynamo. Maunder Minimum (1645–1715 AD) is representative minimum. cyclic variation especially cycle length during this period, critical understand dynamo but remains unknown. By analyzing variations in activity‐related equatorial auroras recorded Korean historical books vicinity low‐intensity paleo‐West Pacific geomagnetic anomaly, we find clear...
