| 1 | Thermodynamic Analysis of a Mixed Refrigerant Ejector Refrigeration Cycle Operating with Two Vapor-liquid Separators显示文摘A mixed refrigerant ejector refrigeration cycle operating with two-stage vapor-liquid separators(MRERC2) is proposed to obtain refrigeration temperature at-40℃. The thermodynamic investigations on performance of MRERC2 using zeotropic mixture refrigerant R23/R134 a are performed, and the comparisons of cycle performance between MRERC2 and MRERC1(MRERC with one-stage vapor-liquid separator) are conducted. The results show that MRERC2 can achieve refrigeration temperature varying between-23.9℃ and-42.0℃ when ejector pressure ratio ranges from 1.6 to 2.3 at the generation temperature of 57.3-84.9℃. The parametric analysis indicates that increasing condensing temperature decreases coefficient of performance(COP) of MRERC2, and increasing ejector pressure ratio and mass fraction of the low boiling point component in the mixed refrigerant can improve COP of MRERC2. The MRERC2 shows its potential in utilizing low grade thermal energy as driving power to obtain low refrigeration temperature for the ejector refrigeration cycle. | TAN Yingying CHEN Youming WANG Lin | 2018 | Journal of Thermal Science2018，27，3： | 12 |

| 6 | A highly selective dual-channel Hg^(2+) chemosensor based on an easy to prepare double naphthalene Schiff base显示文摘A non-sulfur chemosensor based on an easy to prepare double naphthalene Schiff base is reported for the colorimetric and fluorometric dual-channel sensing of Hg2+ ions by taking advantage of the twisted intramolecular charge transfer (TICT) mechanism. This work provides a novel approach for the selective recognition of mercury ions. Moreover, this sensor serves as a potential recyclable component in sensing materials and the complex L-Hg2+ (L = 1-[(2-naphthalenylimino)methyl]-2-naphthalenol) can therefore be used as a fluorescent sensor for iodine anions. Notably, the color changes are very significant and all the recognition and recycling processes can be observed by the naked eye. | ZHANG YouMing SHI BingBing ZHANG Peng HUO JianQiang CHEN Pei LIN Qi LIU Jun WEI TaiBao | 2013 | Science China Chemistry2013，56，5： | 4 |
| 7 | A novel pathway regulates social hierarchy via lncRNA AtLAS and postsynaptic synapsin Ⅱb显示文摘Dominance hierarchy is a fundamental phenomenon in grouped animals and human beings,however,the underlying regulatory mechanisms remain elusive.Here,we report that an antisense long non-coding RNA(lncRNA)of synapsinⅡ;named as AtLAS,plays a crucial role in the regulation of social hierarchy.AtLAS is decreased in the prefrontal cortical excitatory pyramidal neurons of dominant mice;consistently,silencing or overexpression of AtLAS increases or decreases the social rank,respectively.Mechanistically,we show that AtLAS regulates alternative polyadenylation of synapsinⅡgene and increases synapsin 2b(syn2b)expression.Syn2b reduces AMPA receptor(AMPAR)-mediated excitatory synaptic transmission through a direct binding with AMPAR at the postsynaptic site via its unique C-terminal sequence.Moreover,a peptide disrupting the binding of syn2b with AMPARs enhances the synaptic strength and social ranks.These findings reveal a novel role for lncRNA AtLAS and its target syn2b in the regulation of social behaviors by controlling postsynaptic AMPAR trafficking. | Mei Ma Wan Xiong Fan Hu Man-Fei Deng Xian Huang Jian-Guo Chen Heng-Ye Man Youming Lu Dan Liu Ling-Qiang Zhu | 2020 | Cell Research2020，30，2： | 3 |
| 8 | Determination of ginsenoside compound K in human plasma by liquid chromatography–tandem mass spectrometry of lithium adducts显示文摘Ginsenoside compound K(GCK), the main metabolite of protopanaxadiol constituents of Panax ginseng, easily produces alkali metal adduct ions during mass spectrometry particularly with lithium. Accordingly, we have developed a rapid and sensitive liquid chromatography–tandem mass spectrometric method for analysis of GCK in human plasma based on formation of a lithium adduct. The analyte and paclitaxel(internal standard) were extracted from 50 m L human plasma using methyl tertbutyl ether. Chromatographic separation was performed on a Phenomenex Gemini C18 column(50 mm 2.0 mm; 5 μm) using stepwise gradient elution with acetonitrile–water and 0.2 mmol/L lithium carbonate at a flow rate of 0.5 m L/min. Detection was performed in the positive ion mode using multiple reaction monitoring of the transitions at m/z 629-449 for the GCK-lithium adduct and m/z 860-292 for the adduct of paclitaxel. The assay was linear in the concentration range 1.00–1000 ng/m L(r^2>40.9988)with intra- and inter-day precision of ±8.4% and accuracy in the range of 4.8% to 6.5%. Recovery,stability and matrix effects were all satisfactory. The method was successfully applied to a pharmacokinetic study involving administration of a single GCK 50 mg tablet to healthy Chinese volunteers. | Yunhui Chen Youming Lu Yong Yang Xiaoyan Chen Liang Zhu Dafang Zhong | 2015 | Acta Pharmaceutica Sinica B2015，5，5： | 3 |

| 10 | Achieving high conversion of syngas to aromatics显示文摘Realizing high CO conversion and high aromatics selectivity simultaneously in syngas-to-aromatics(STA)reaction is still challenging.Herein,we report a 57.5%CO conversion along with 74%aromatics selectivity over a composite catalyst consisting of Fe/ZnCr_(2)O_(4)(Fe modified ZnCr_(2)O_(4)spinel)oxide and H-ZSM-5 zeolite.Impregnation of only 3 wt%of Fe onto ZnCr_(2)O_(4)can remarkably increase CO conversion without sacrificing the aromatics selectivity.Oxygen vacancy concentration is improved after impregnating Fe.The highly dispersed iron carbide species is formed during the reaction over Fe/ZnCr_(2)O_(4)spinel oxide.The synergistic effect of oxygen vacancy and iron carbide results in a rapid formation of abundant oxygenated intermediate species,which can be continuously transformed to aromatics in H-ZSM-5.This study provides a new insight into the design of highly efficient catalyst for syngas conversion. | Yi Fu Youming Ni Zhiyang Chen Wenliang Zhu Zhongmin Liu | 2022 | Journal of Energy Chemistry2022，31，3： | 2 |
| 11 | VGLUT3 neurons in median raphe control the efficacy of spatial memory retrieval via ETV4 regulation of VGLUT3 transcription显示文摘The raphe nucleus is critical for feeding, rewarding and memory. However, how the heterogenous raphe neurons are molecularly and structurally organized to engage their divergent functions remains unknown. Here, we genetically target a subset of neurons expressing VGLUT3. VGLUT3 neurons control the efficacy of spatial memory retrieval by synapsing directly with parvalbumin-expressing GABA interneurons(PGIs) in the dentate gyrus. In a mouse model of Alzheimer's disease(AD mice),VGLUT3→PGIs synaptic transmission is impaired by ETV4 inhibition of VGLUT3 transcription. ETV4 binds to a promoter region of VGLUT3 and activates VGLUT3 transcription in VGLUT3 neurons. Strengthening VGLUT3→PGIs synaptic transmission by ETV4 activation of VGLUT3 transcription upscales the efficacy of spatial memory retrieval in AD mice. This study reports a novel circuit and molecular mechanism underlying the efficacy of spatial memory retrieval via ETV4 inhibition of VGLUT3 transcription and hence provides a promising target for therapeutic intervention of the disease progression. | Aodi He Chen Zhang Xiao Ke Yao Yi Quntao Yu Tongmei Zhang Hongyan Yu Huiyun Du Hao Li Qing Tian Ling-Qiang Zhu Youming Lu | 2022 | Science China(Life Sciences)2022，65，8： | 2 |
| 12 | Effects of structural and operating parameters of ECP fan on dust particles removed in the transition flow regime显示文摘An enclosed cyclone passageway(ECP)dust-collecting fan is discussed.The ECP fan separates dust by centrifugal force originating from a driven spiral airflow,and its design takes the constraints of Chinese underground coal mines into consideration.Using the force equilibrium law,a general equation for dust removal in the centrifugal dust removal section(CDRS)of the ECP fan is deduced.This general equation is simplified using the CDRS structure and the fan operating parameters and is analysed numerically.The attractive results show that increases in the airflow rate of the fan,the structural ratio of the ECPs and the radius of the extended axis can improve the dust removal performance of the CDRS.Furthermore,the effects of the structural ratio and the radius on dust removal dominate over that of the flow rate,and the effect of the structural ratio is more significant than that of the radius. | Shiqiang Chen Youming Chen Haiqiao Wang Ronghua Liu Haijiao Cui | 2014 | International Journal of Coal Science & Technology2014，1，4： | 2 |
| 13 | Polar codes: Encoding/decoding and rate-compatible jointly design for HARQ system显示文摘Polar coding are the first class of provable capacity-achieving coding techniques for a wide range of channels.With an ideal recursive structure and many elegant mathematical properties,polar codes are inherently implemented with low complexity encoding and decoding algorithms.Since the block length of the original polar construction is limited to powers of two,rate-compatible polar codes(RCPC)are presented to meet the flexible length/rate transmission requirements in practice.The RCPC codes are well-conditioned to combine with the hybrid automatic repeat request(HARQ)system,providing high throughput efficiency and such RCPC-HAPQ scheme is commonly used in delay-insensitive communication system.This paper first gives a survey of both the classical and state-of-the-art encoding/decoding algorithms for polar codes.Then the RCPC construction methods are discussed,including the puncturing,shortening,multi-kernel construction,etc.Finally,we investigate several RCPC-HARQ jointly design systems and discuss their encoding gain and re-transmission diversity gain. | Qiaoli Zeng Quan Zhou Xiangkun He Youming Sun Xiangcheng Li Haiqiang Chen | 2021 | Intelligent and Converged Networks2021，2，4： | 1 |
