| 1 | Epidemiological Characteristics of Osteoarthritis in Yichang City—Hubei Province,China,2017–2018显示文摘Summary What is already known about this topic?OA has been listed as the fastest increasing major public health problem and ranked second as a cause of disability by World Health Organization(WHO).With population aging,osteoarthritis(OA)is causing an increased economic burden for individuals and society and is attracting an increasing amount of scientific attention. | Yingying Zhang Jiajuan Yang Tanchun Yu Li Ma Yuewei Cheng Xudong Li | 2021 | China CDC weekly2021，3，16： | 2 |
| 2 | Optically-generated focused ultrasound for noninvasive brain stimulation with ultrahigh precision显示文摘High precision neuromodulation is a powerful tool to decipher neurocircuits and treat neurological diseases.Current non-invasive neuromodulation methods offer limited precision at the milimeter level.Here,we report opticallygenerated focused ultrasound(OFUS)for non-invasive brain stimulation with ultrahigh precision.OFUS is generated by a soft optoacoustic pad(SOAP)fabricated through embedding candle soot nanoparticles in a curved polydimethylsiloxane film.SOAP generates a transcranial ultrasound focus at 15 MHz with an ultrahigh lateral resolution of 83μm,which is two orders of magnitude smaller than that of conventional transcranial-focused ultrasound(tFUS).Here,we show effective OFUS neurostimulation in vitro with a single ultrasound cycle.We demonstrate submillimeter transcranial stimulation of the mouse motor cortex in vivo.An acoustic energy of 0.6 mJ/cm?,four orders of magnitude less than that of tFUS,is suffcient for successful OFUS neurostimulation.OFUS offers new capabilities for neuroscience studies and disease treatments by delivering a focus with ultrahigh precision noninvasively. | Yueming Li Ying Jiang Lu Lan Xiaowei Ge Ran Cheng Yuewei Zhan Guo Chen Linli Shi Runyu Wang Nan Zheng Chen Yang Ji-Xin Cheng | 2022 | Light(Science & Applications)2022，11，11： | 1 |
| 3 | Luminescent gold(Ⅲ)exciplexes enable efficient multicolor electroluminescence显示文摘The control of excited states and related emissive properties of gold(Ⅲ)complexes mainly depends on the modulation of intramolecular electronic interactions among gold(Ⅲ)metal center,chelating ligands and/or peripheral groups.However,luminescent gold(Ⅲ)systems based on intermolecular electronic interactions have never been explored.Here we report a series of proof-of-concept gold(Ⅲ)exciplexes using a simple gold(Ⅲ)complex,AuDPPy,as an electron acceptor.The emissive properties of gold(Ⅲ)exciplexes can be regulated by combining AuDPPy with different donors.Inspiringly,these gold(Ⅲ)exciplexes have donor-dependent emission mechanisms:dominant phosphorescence or dual radiative channels of thermally activated delayed fluorescence(TADF)and phosphorescence.Consequently,these gold(Ⅲ)exciplexes deliver green-to-red electroluminescence with external quantum efficiencies(EQEs)of up to 10.1%.More importantly,using these gold(Ⅲ)exciplexes to host multi-resonance TADF emitters results in narrowband yellow,orange,and deep-red electroluminescence with high EQEs of 23.5%,24.4%,and 27.4%,respectively,competitive to the highest values for gold(Ⅲ)OLEDs in similar color gamut. | Lisi Zhan Tianhao Chen Cheng Zhong Xiaosong Cao Yuewei Zhang Yang Zou Zhengyang Bin Jingsong You Dongdong Zhang Lian Duan Chuluo Yang Shaolong Gong | 2023 | Science China Chemistry2023，66，11： | 0 |
| 4 | An Observing System Simulation Experiment to Assess the Potential Impact of a Virtual Mobile Communication Tower–based Observation Network on Weather Forecasting Accuracy in China. Part 1: Weather Stations with a Typical Mobile Tower Height of 40 m显示文摘The importance of a national or regional network of meteorological stations for improving weather predictions has been recognized for many years.Ground-based automatic weather stations typically observe weather at a height of 2-10 m above ground level(AGL);however,these observations may have two major shortcomings.Large portions of data cannot be used if the station height is significantly lower than the model surface level;and such observations may contain large representativity errors as near-surface observations are often affected by the local environment,such as nearby buildings and tall trees.With the recent introduction of a significant number of mobile communication towers that are typically over40 m AGL in China,a campaign has been proposed to use such towers to build a future observing system with an observing height of 40 m.A series of observing system simulation experiments has been conducted to assess the potential utility of such a future observing system as part of a feasibility study.The experiments were conducted using the Weather Research and Forecasting model and its Rapid Update Cycle data assimilation system.The results revealed the possibility of improving weather forecasting by raising present weather stations to a height of 40 m;this would not only enable more observations to pass the terrain check,but should also reduce interpolation errors.Additionally,improvements for temperature,humidity and wind forecasting could be achieved as the accuracy of the initial conditions increases. | Xuanming ZHAO Jiang ZHU Lijing CHENG Yubao LIU Yuewei LIU | 2020 | Advances in Atmospheric Sciences2020，37，6： | 0 |
