| 1 | Design scheme for fast charging station for electric vehicles with distributed photovoltaic power generation显示文摘The demand for fast charging is increasing owing to the rapid expansion of the market for electric vehicles. In addition, the power generation technology for distributed photovoltaic has matured. This paper presents a design scheme for a fast charging station for electric vehicles equipped with distributed photovoltaic power generation system taking the area with certain conditions in Beijing as an example construction site. The technical indexes and equipment lectotype covering the general framework and subsystems of the charging station are determined by analyzing the charging service demand of fast charging stations. In this study, the layout of the station is developed and the operation benefits of the station is analyzed. The design scheme realizes the design objective of 'rationalization, modularization and intelligentization' of the fast charging station and can be used as reference for the construction of a fast charging network in urban area. | Jing Zhang Chang Liu Ruiming Yuan Taoyong Li Kang Li Bin Li Jianxiang Li Zhenyu Jiang | 2019 | Global Energy Interconnection2019，2，2： | 12 |
| 2 | Mesenchymal stromal cells alleviate acute respiratory distress syndrome through the cholinergic anti-inflammatory pathway显示文摘Mesenchymal stromal cells(MSCs)have been considered a promising alternative for treatment of acute respiratory distress syndrome(ARDS).However,there is significant heterogeneity in their therapeutic efficacy,largely owing to the incomplete understanding of the mechanisms underlying the therapeutic activities of MSCs.Here,we hypothesize that the cholinergic antiinflammatory pathway(CAP),which is recognized as a neuroimmunological pathway,may be involved in the therapeutic mechanisms by which MSCs mitigate ARDS.Using lipopolysaccharide(LPS)and bacterial lung inflammation models,we found that inflammatory cell infiltration and Evans blue leakage were reduced and that the expression levels of choline acetyltransferase(ChAT)and vesicular acetylcholine transporter(VAChT)in lung tissue were significantly increased 6 hours after MSC infusion.When the vagus nerve was blocked orα7 nicotinic acetylcholine(ACh)receptor(α7nAChR)-knockout mice were used,the therapeutic effects of MSCs were significantly reduced,suggesting that the CAP may play an important role in the effects of MSCs in ARDS treatment.Our results further showed that MSC-derived prostaglandin E2(PGE2)likely promoted ACh synthesis and release.Additionally,based on the efficacy of nAChR andα7nAChR agonists,we found that lobeline,the nicotinic cholinergic receptor excitation stimulant,may attenuate pulmonary inflammation and alleviate respiratory symptoms of ARDS patients in a clinical study(ChiCTR2100047403).In summary,we reveal a previously unrecognized MSC-mediated mechanism of CAP activation as the means by which MSCs alleviate ARDS-like syndrome,providing insight into the clinical translation of MSCs or CAP-related strategies for the treatment of patients with ARDS. | Xiaoran Zhang Xuxia Wei Yiwen Deng Xiaofeng Yuan Jiahao Shi Weijun Huang Jing Huang Xiaoyong Chen Shuwei Zheng Jieying Chen Keyu Chen Ruiming Xu Hongmiao Wang Weiqiang Li Shiyue Li Huimin Yi Andy Peng Xiang | 2022 | Signal Transduction and Targeted Therapy2022，7，10： | 1 |
| 3 | Hertz-rate metropolitan quantum teleportation显示文摘Quantum teleportation can transfer an unknown quantum state between distant quantum nodes,which holds great promise in enabling large-scale quantum networks.To advance the full potential of quantum teleportation,quantum states must be faithfully transferred at a high rate over long distance.Despite recent impressive advances,a high-rate quantum teleportation system across metropolitan fiber networks is extremely desired.Here,we demonstrate a quantum teleportation system which transfers quantum states carried by independent photons at a rate of 7.1±0.4 Hz over 64-km-long fiber channel.An average single-photon fidelity of≥90.6±2.6%is achieved,which exceeds the maximum fidelity of 2/3 in classical regime.Our result marks an important milestone towards quantum networks and opens the door to exploring quantum entanglement based informatic applications for the future quantum internet. | Si Shen Chenzhi Yuan Zichang Zhang Hao Yu Ruiming Zhang Chuanrong Yang Hao Li Zhen Wang You Wang Guangwei Deng Haizhi Song Lixing You Yunru Fan Guangcan Guo Qiang Zhou | 2023 | Light(Science & Applications)2023，12，6： | 0 |
| 4 | Spectrally multiplexed indistinguishable single-photon generation at telecom-band显示文摘Heralded single-photon source(HSPS)intrinsically suffers from the trade-off between the heralded single-photon rate and the single-photon purity.To break through this trade-off,one can apply multiplexing technology in different degrees of freedom that significantly improves the performance of the HSPS.Here,we propose a 1.5μm chip-scale HSPS on lithium niobate on insulator by employing spectral multiplexing and active feedforward spectral manipulating,and we demonstrate a proof-of-principle experiment with discrete fiber-based components.With continuous-wave laser pumping and three spectral modes multiplexed,our experimental results show that the spectral multiplexing improves the heralded single-photon rate by near threefold while keeping the g^((2))(0)as low as 0.0006±0.0001 at a measured single-photon rate of 3.1 kHz.By measuring the joint spectral intensity,we show that the spectral multiplexing and feed-forward control effectively erase the frequency correlation of photon pairs.Moreover,we implement the Hong-Ou-Mandel interference between the spectrally multiplexed single photons and photons from an independent weak coherence source,which indicates that the multiplexed single photons are highly indistinguishable after the spectral manipulation.Our results pave a way for on-chip scalable and high-performance HSPS with spectral multiplexing toward deterministic single-photon emission. | HAO YU CHENZHI YUAN RUIMING ZHANG ZICHANG ZHANG HAO LI YOU WANG GUANGWEI DENG LIXING YOU HAIZHI SONG ZHIMING WANG GUANG-CAN GUO QIANG ZHOU | 2022 | Photonics Research2022，10，6： | 0 |
