| 1 | Distribution patterns of 210Po, 210Pb and the particle export in the Taiwan Strait during the winter显示文摘210Po and 210Pb are increasingly used to constrain particle dynamics in the open oceans,however they are less used in coastal waters.Here,distributions and partitions of 210Po and 210Pb were examined in the Taiwan Strait,as well as their application to quantify particle sinking.Activity concentrations of dissolved 210Po and 210Pb(<0.6μm)ranged from 1.21 to 7.63 dpm/(100 L)and from 1.07 to 6.33 dpm/(100 L),respectively.Activity concentrations of particulate 210Po and 210Pb varied from 1.96 to 36.74 dpm/(100 L)and from 3.11 to 38.06 dpm/(100 L).Overall,particulate 210Po and 210Pb accounted for the majority of the bulk 210Po and 210Pb.210Po either in dissolved or particulate phases showed similar spatial patterns to 210Pb,indicating similar mechanisms for controlling the distributions of 210Po and 210Pb in the Taiwan Strait.The different fractionation coefficients indicated that particles in the Zhemin Coastal Current(ZCC)inclined to absorb 210Po prior to 210Pb while they showed an opposite effect in the Taiwan Warm Current(TWC).Based on the disequilibria between 210Po and 210Pb,the sinking fluxes of total particulate matter(TPM)were estimated to range from–0.22 to 3.84 g/(m2·d),showing an overall comparable spatial distribution to previous reported sediment accumulation rates.However,our sinking fluxes were lower than the sedimentation rates,indicating a sediment resuspension in winter and horizontal transport of particulate matter from the Taiwan Strait to the East China Sea. | Lihao Zhang Weifeng Yang Min Chen Yinian Zhu Zhou Wang Ziming Fang Yusheng Qiu Yanhong | 2020 | Acta Oceanologica Sinica2020，39，2： | 1 |
| 2 | SEMG-based fighter pilot muscle fatigue analysis and operation performance research显示文摘Fatigue has a tremendously adverse impact on pilot performance.This study aims to explore the Biceps Brachii(BB),Rectus Femoris(RF),Flexor Carpi Radialis(FCR),and Tibialis Anterior(TA)activities of fighter pilots in the early and late combat stages,and the target hitting time.A total of 13 volunteers were recruited to conduct simulated combats inside a real fighter cockpit.The surface Electromyography(sEMG)was collected from all volunteers in the initial and final 20s of flight,and the target hitting time during three simulated combats was recorded.The root mean square(RMS)values of right BB and TA were significantly higher than the left side values(p<0.001),while insignificant differences were found in the RMS values between the bilateral RF and FCR.Compared to the early flight period,the median frequency(MF)values of BB and TA were significantly lower during the late flight period,and the RMS values were significantly higher(p<0.047).Contrastively,the RMS values of FCR and RF differed insignificantly during the late flight period.Regarding the target hitting time,a significant difference was noted between task 1 and rask3.Subjects exhibit varying levels of muscle fatigue for different muscle groups before and after the flight.The muscle fatigue levels are asymmetrical on the left and right sides.Muscle fatigue might reduce the pilots'operational ability.This study provides a reference for fighter pilot fatigue protection and treatment. | Biyun Zhou Bo Chen Huijuan Shi Lihao Xue Yingfang Ao Li Ding | 2022 | Medicine in Novel Technology and Devices2022，，4： | 0 |
| 3 | Antioxidant-enriched autologous biogel promoted diabetic wound healing by remodeling inherent posttraumatic inflammatory patterning and restoring compromised microenvironment homeostasis显示文摘Successful wound healing depends on the reconstruction of proper tissue homeostasis,particularly in the posttraumatic inflammatory tissue microenvironment.Diabetes jeopardizes tissues’immune homeostasis in cutaneous wounds,causing persistent chronic inflammation and cytokine dysfunction.Previously,we developed an autologous regeneration factor(ARF)technology to extract the cytokine composite from autologous tissue to restore immune homeostasis and promote wound healing.However,treatment efficacy was significantly compromised in diabetic conditions.Therefore,we proposed that a combination of melatonin and ARF,which is beneficial for proper immune homeostasis reconstruction,could be an effective treatment for diabetic wounds.Our research showed that the utilization of melatonin-mediated ARF biogel(AM gel)promoted diabetic wound regeneration at a more rapid healing rate.RNA-Seq analysis showed that AM gel treatment could restore more favorable immune tissue homeostasis with unique inflammatory patterning as a result of the diminished intensity of acute and chronic inflammation.Currently,AM gel could be a novel and promising therapeutic strategy for diabetic wounds in clinical practice through favorable immune homeostatic reconstructions in the tissue microenvironment and proper posttraumatic inflammation patterning. | Yixi Yang Le Wang Yonglin Zhou Yijun He Shaozhang Lin Yuwei Zeng Yunhe Zhou Wei Li Zaopeng He Qi Zhao Lihao Chen Zijie Li Wenhao Wang Zhi-Yong Zhang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 4 | Atomic layer deposition to heterostructures for application in gas sensors显示文摘Atomic layer deposition(ALD) is a versatile technique to deposit metals and metal oxide sensing materials at the atomic scale to achieve improved sensor functions. This article reviews metals and metal oxide semiconductor(MOS) heterostructures for gas sensing applications in which at least one of the preparation steps is carried out by ALD. In particular, three types of MOS-based heterostructures synthesized by ALD are discussed, including ALD of metal catalysts on MOS, ALD of metal oxides on MOS and MOS core–shell(C–S) heterostructures.The gas sensing performances of these heterostructures are carefully analyzed and discussed.Finally, the further developments required and the challenges faced by ALD for the synthesis of MOS gas sensing materials are discussed. | Hongyin Pan Lihao Zhou Wei Zheng Xianghong Liu Jun Zhang Nicola Pinna | 2023 | International Journal of Extreme Manufacturing2023，5，2： | 0 |
| 5 | A Novel Robotic Control System Mimics Doctor’s Operation to Assist Percutaneous Coronary Intervention显示文摘Objectives:The use of current robotic systems to assist in percutaneous coronary intervention(PCI)fundamentally differs from performing conventional PCI.To overcome this problem,we developed a novel master-slave robotic control system to assist in PCI,and evaluated its safety and feasibility in the delivery and manipulation of coronary guidewires in vitro and in vivo.Methods:The novel robotic assist PCI system is composed of three parts:1)a master actuator,which imitates the traditional torque used by surgeons in conventional PCI,2)a slave actuator,including a guidewire delivery system and force monitoring equipment,and 3)a local area network based communication system.Results:The experiment was performed in six pigs.Both robotic and manual control completed the operation with no device-or procedure-associated complications.An experienced interventional cardiologist who was afirst-time user of the novel robotic PCI system was able to advance the guidewire into a distal branch of a coronary artery within a similar time to that required with the manual procedure.Conclusion:This early in vivo experiment with the novel robotic assisted PCI control system demonstrated that its feasibility,safety,and procedural effectiveness are comparable to those of manual operation.The novel robotic-assisted PCI control system required significantly less time to learn than other currently available systems. | Boda Zhou Qizhong Li Yajun Xue Lihao Huang Jie Zhou Ou Zhang Ping Zhang Gangtie Zheng | 2022 | Cardiovascular Innovations and Applications2022，6，2： | 0 |
