| 1 | Source Contributions to PM2.5 under Unfavorable Weather Conditions in Guangzhou City,China显示文摘Historical haze episodes(2013–16) in Guangzhou were examined and classified according to synoptic weather systems.Four types of weather systems were found to be unfavorable, among which 'foreside of a cold front'(FC) and 'sea high pressure'(SP) were the most frequent(> 75% of the total). Targeted case studies were conducted based on an FC-affected event and an SP-affected event with the aim of understanding the characteristics of the contributions of source regions to fine particulate matter(PM_(2.5)) in Guangzhou. Four kinds of contributions—namely, emissions outside Guangdong Province(super-region), emissions from the Pearl River Delta region(PRD region), emissions from Guangzhou–Foshan–Shenzhen(GFS region), and emissions from Guangzhou(local)—were investigated using the Weather Research and Forecasting–Community Multiscale Air Quality model. The results showed that the source region contribution differed with different weather systems. SP was a stagnant weather condition, and the source region contribution ratio showed that the local region was a major contributor(37%), while the PRD region, GFS region and the super-region only contributed 8%, 2.8% and 7%, respectively, to PM_(2.5) concentrations. By contrast, FC favored regional transport. The super-region became noticeable,contributing 34.8%, while the local region decreased to 12%. A simple method was proposed to quantify the relative impact of meteorology and emissions. Meteorology had a 35% impact, compared with an impact of-18% for emissions, when comparing the FC-affected event with that of the SP. The results from this study can provide guidance to policymakers for the implementation of effective control strategies. | Nan WANG Zhenhao LING Xuejiao DENG Tao DENG Xiaopu LYU Tingyuan LI Xiaorong GAO Xi CHEN | 2018 | Advances in Atmospheric Sciences2018，35，9： | 5 |
| 2 | Experiment and simulation of foaming injection molding of polypropylene/nano-calcium carbonate composites by supercritical carbon dioxide显示文摘Microcellular injection molding of neat isotactic polypropylene(iPP) and isotactic polypropylene/nano-calcium carbonate composites(i PP/nano-CaCO_3) was performed using supercritical carbon dioxide as the physical blowing agent. The influences of filler content and operating conditions on microstructure morphology of i PP and i PP/nano-CaCO_3 microcellular samples were studied systematically. The results showed the bubble size of the microcellular samples could be effectively decreased while the cell density increased for i PP/nano-CaCO_3 composites, especially at high CO_2 concentration and back pressure, low mold temperature and injection speed, and high filler content. Then Moldex 3D was applied to simulate the microcellular injection molding process, with the application of the measured ScCO_2 solubility and diffusion data for i PP and i PP/nano-Ca CO_3 composites respectively. For neat i PP, the simulated bubble size and density distribution in the center section of tensile bars showed a good agreement with the experimental values. However, for i PP/nano-CaCO_3 composites, the correction factor for nucleation activation energy F and the pre-exponential factor of nucleation rate f_0 were obtained by nonlinear regression on the experimental bubble size and density distribution. The parameters F and f_0 can be used to predict the microcellular injection molding process for i PP/nano-CaCO_3 composites by Moldex 3D. | Zhenhao Xi Jie Chen Tao Liu Ling Zhao Lih-Sheng Turng | 2016 | Chinese Journal of Chemical Engineering2016，24，1： | 4 |

| 4 | Polyvalent mRNA vaccination elicited potent immune response to monkeypox virus surface antigens显示文摘Dear Editor,The global monkeypox(Mpox)outbreak leads to a surge in demand for vaccine.The Mpox vaccine in short supply is JYNNEOS(modified vaccinia ankara,MVA)due to less side effects,while ACAM2000 supply is abundant because of the strategic stockpile in U.s.1 The ACAM2000 replaced the first-generation smallpox vaccine Dryvax that has a questionable safety profile.However,the ACAM2000 is associated with high rate of myocarditis and pericarditis,and can cause severe illness in immunocompromised patients,foreshadowing the need to update the strategic stockpile. | Zhenhao Fang Valter S.Monteiro Paul A.Renauer Xingbo Shang Kazushi Suzuki Xinyu Ling Meizhu Bai Yan Xiang Andre Levchenko Carmen J.Booth Carolina Lucas Sidi Chen | 2023 | Cell Research2023，33，5： | 1 |
| 5 | In situ growth of hydrophilic nickel-cobalt layered double hydroxides nanosheets on biomass waste-derived porous carbon for high-performance hybrid supercapacitors显示文摘Rational design and cost-effective fabrication of layered double hydroxides(LDHs)nanosheets with extraordinary electrochemical performance is a key challenge for hybrid supercapacitors(HSCs).Herein,we report a facile in situ growth methodology to eco-friendly synthesize hydrophilic Ni Co-LDHs nanosheets on biomass waste-derived porous carbon(BC)for robust high-performance HSC cathode.The in situ growth process under ultrasonication realizes the rational arrangement of Ni Co-LDHs nanosheets on the surface of BC,which effectively increases the specific surface area,promotes the electronic conductivity and enhances the wettability of Ni Co-LDHs nanosheets without affecting their thickness values.With the beneficial effects of ultrathin thickness of LDHs nanosheets(6.20 nm),large specific surface area(2324.1 m^(2)g^(-1)),low charge transfer resistance(1.65Ω),and high wettability with electrolyte(34°–35°),the obtained Ni2Co1-LDHs/BC50 electrode possesses an ultra-high specific capacitance of 2390 F g^(-1)(956 C g^(-1))at 1 A g^(-1),which is superior to most reported values.Furthermore,an assembled Ni_(2)Co_(1)-LDHs/BC50//YP-80F HSC delivers a maximum specific energy of 52.47 Wh kg^(-1)at375 W kg^(-1),and maintains a high capacitance retention of 75.9%even after 4000 cycles.This work provides a facile approach to fabricate LDHs nanosheets based cathode materials for high-performance HSCs. | Yuchen Wang Yaoyu Liu Zuo Chen Man Zhang Biying Liu Zhenhao Xu Kai Yan | 2022 | Green Chemical Engineering2022，3，1： | 1 |

| 10 | Intravenous route to choroidal neovascularization by macrophage-disguised nanocarriers for mTOR modulation显示文摘Retinal pigment epithelial(RPE) is primarily impaired in age-related macular degeneration(AMD), leading to progressive loss of photoreceptors and sometimes choroidal neovascularization(CNV). mTOR has been proposed as a promising therapeutic target, while the usage of its specific inhibitor,rapamycin, was greatly limited. To mediate the mTOR pathway in the retina by a noninvasive approach, we developed novel biomimetic nanocomplexes where rapamycin-loaded nanoparticles were coated with cell membrane derived from macrophages(termed as MRaNPs). Taking advantage of the macrophage-inherited property, intravenous injection of MRaNPs exhibited significantly enhanced accumulation in the CNV lesions, thereby increasing the local concentration of rapamycin. Consequently, MRaNPs effectively downregulated the mTOR pathway and attenuate angiogenesis in the eye. Particularly, MRaNPs also efficiently activated autophagy in the RPE, which was acknowledged to rescue RPE in response to deleterious stimuli. Overall, we design and prepare macrophage-disguised rapamycin nanocarriers and demonstrate the therapeutic advantages of employing biomimetic cell membrane materials for treatment of AMD. | Weiyi Xia Chao Li Qinjun Chen Jiancheng Huang Zhenhao Zhao Peixin Liu Kai Xu Lei Li Fangyuan Hu Shujie Zhang Tao Sun Chen Jiang Chen Zhao | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 1 |
| 11 | No Male Preference for Large Females in the Asian Common Toad(Duttaphrynus melanostictus):Effect of the Sex Ratio and Breeding System显示文摘Mating preferences are common in natural populations of animals.Numerous studies have shown that male mate choice can occur in a wide range of taxa.However,male mating preferences are still poorly understood in anurans.Sexual selection theory predicts that male mate choice is not expected to arise if 1) adult population exhibited a highly male-biased sex ratio which will diminish male mating success;2) males provide less parental care;3) mating success of males is associated with chorus tenure in which males would maximize their fitness by mating with multiple mates.We tested these predictions in the Asian common toad Duttaphrynus melanostictus from southeastern Tibet,China.Our field experimental results indicated that,the breeding population exhibited a highly male-biased sex ratio,called males did not defend sites which contain significant resources required by females and offspring,both sexes provided no parental care after egg-laying,and the toad species was characterized with prolonged breeding season chorus attendance.In male mate choice experiment,males did not show preferences for a larger gravid female over a smaller gravid female.We suggest that male mating success in the Asian common toad is likely determined by the number but not the quality of mates.Future research should focus on how sexual selection on male acoustic signaling and how female preference exert different types of selection pressure on male call traits in this Tibet toad. | Lixia ZHANG Xiangyu YUAN Yongsun SHENG Xueting ZHONG Jiahong LIAO Zhenhao LIU Wei CHEN | 2020 | Asian Herpetological Research2020，11，4： | 0 |
| 12 | Field theoretical approach to spin models显示文摘We developed a systematic non-perturbative method base on Dyson–Schwinger theory and theΦ-derivable theory for Ising model at broken phase.Based on these methods,we obtain critical temperature and spin spin correlation beyond mean field theory.The spectrum of Green function obtained from our methods become gapless at critical point,so the susceptibility become divergent at Tc.The critical temperature of Ising model obtained from this method is fairly good in comparison with other non-cluster methods.It is straightforward to extend this method to more complicate spin models for example with continue symmetry. | Feng Liu Zhenhao Fan Zhipeng Sun Xuzong Chen Dingping Li | 2021 | Frontiers of physics2021，16，6： | 0 |

| 14 | The nodule-specific transcriptional repressor Top Hub 4 regulates nodule structure and nitrogen fixation capacity in soybean显示文摘Most leguminous plants establish symbiotic relationships with rhizobia to form root organs called nodules(Ferguson et al.,2010).Nodules are specialized organs containing bacterial symbionts,which can provide enormous amounts of fixed nitrogen to their plant hosts(Peoples et al.,2009).Soybean(Glycine max),an economically important grain and oil crop,forms symbiotic nitrogen-fixing nodules,which reduces the demand for chemical nitrogen fertilizers and promotes yield(Saito et al.,2014).Nodule development is spatiotemporally regulated by the action of a number of transcription factors(TFs). | Kui Ge Qi Lv Shengcai Chen Zhenhao Guo Yaqi Peng Yimian Chen Shiyong Sun Xuelu Wang | 2024 | Journal of Genetics and Genomics2024，51，1： | 0 |
| 15 | In silico prediction methods of self-interacting proteins:an empirical and academic survey显示文摘In silico prediction of self-interacting proteins(SIPs)has become an important part of proteomics.There is an urgent need to develop effective and reliable prediction methods to overcome the disadvantage of high cost and labor intensive in traditional biological wet-lab experiments.The goal of our survey is to sum up a comprehensive overview of the recent literature with the computational SIPs prediction,to provide important references for actual work in the future.In this review,we first describe the data required for the task of DTIs prediction.Then,some interesting feature extraction methods and computational models are presented on this topic in a timely manner.Afterwards,an empirical comparison is performed to demonstrate the prediction performance of some classifiers under different feature extraction and encoding schemes.Overall,we conclude and highlight potential methods for further enhancement of SIPs prediction performance as well as related research directions. | Zhanheng CHEN Zhuhong YOU Qinhu ZHANG Zhenhao GUO Siguo WANG Yanbin WANG | 2023 | Frontiers of Computer Science2023，17，3： | 0 |
| 16 | Nanomaterials with dual immunomodulatory functions for synergistic therapy of breast cancer brain metastases显示文摘A long-standing paucity of effective therapies results in the poor outcomes of triple-negative breast cancer brain metastases.Immunotherapy has made progress in the treatment of tumors,but limited by the non-immunogenicity of tumors and strong immunosuppressive environment,patients with TNBC brain metastases have not yet benefited from immunotherapy.Dual immunoregulatory strategies with enhanced immune activation and reversal of the immunosuppressive microenvironment provide new therapeutic options for patients.Here,we propose a cocktail-like therapeutic strategy of microenvironment regulation-chemotherapy-immune synergistic sensitization and construct reduction-sensitive immune microenvironment regulation nanomaterials(SIL@T).SIL@T modified with targeting peptide penetrates the BBB and is subsequently internalized into metastatic breast cancer cells,releasing silybin and oxaliplatin responsively in the cells.SIL@T preferentially accumulates at the metastatic site and can significantly prolong the survival period of model animals.Mechanistic studies have shown that SIL@T can effectively induce immunogenic cell death of metastatic cells,activate immune responses and increase infiltration of CD8+T cells.Meanwhile,the activation of STAT3 in the metastatic foci is attenuated and the immunosuppressive microenvironment is reversed.This study demonstrates that SIL@T with dual immunomodulatory functions provides a promising immune synergistic therapy strategy for breast cancer brain metastases. | Zhenhao Zhao Chufeng Li Yiwen Zhang Chao Li Yongchao Chu Xuwen Li Peixin Liu Hongyi Chen Yu Wang Boyu Su Qinjun Chen Tao Sun Chen Jiang | 2023 | Bioactive Materials2023，，9： | 0 |

| 20 | Investigation on the Effect of the Multilayered Porous Structure of Sea Urchin Skeleton on Its Mechanical Behavior显示文摘In this paper,the effect of stereom structure on the mechanical behavior of the Sea Urchin Inorganic Skeleton(SUIS)has been studied.The stereom microstructure of both Anthocidaris crassispina and Tripnenstes gratilla was characterized by Scanning Electron Microscopy(SEM).Results indicate that a three-layer porous structure consisting of a growth,a support,and a resorption(GSR)layer is a common denominator for both species.The effect of GSR layer order on the mechanical behavior of the SUIS was studied by a finite element method.The results show that the GSR model could effectively reduce the maximum tensile stress on its meridional sutures under unidirectional pressure,hydrostatic pressure,and self-weight situation.For a fabricated three-layered ceramic test strips with different layer orders,the mechanical properties have a completely opposite performance compared with the compressive properties of the calculated SUIS-Iike models.This indicates that the GSR structure can effectively improve the mechanical properties of the SUIS,but it cannot be applied to bionics without considering its synergistic effect with the macro-structure of the SUIS.This is a typical example of bionic invalidation by single structure,where multi-level structure bionics may be an effective solution. | Hui Yu Jianbao Li Zhenhao Hou Jianlin Li Yongjun Chen Chunfu Lin | 2020 | Journal of Bionic Engineering2020，17，3： | 0 |
