| 1 | Numerical Simulation and Analysis of Solid-liquid Two-phase Flow in Centrifugal Pump显示文摘The flow with solid-liquid two-phase media inside centrifugal pumps is very complicated and the relevant method for the hydraulic design is still immature so far.There exist two main problems in the operation of the two-phase flow pumps,i.e.,low overall efficiency and severe abrasion.In this study,the three-dimensional,steady,incompressible,and turbulent solid-liquid two-phase flows in a low-specific-speed centrifugal pump are numerically simulated and analyzed by using a computational fluid dynamics(CFD) code based on the mixture model of the two-phase flow and the RNG k-two-equation turbulence model,in which the influences of rotation and curvature are fully taken into account.The coupling between impeller and volute is implemented by means of the frozen rotor method.The simulation results predicted indicate that the solid phase properties in two-phase flow,especially the concentration,the particle diameter and the density,have strong effects on the hydraulic performance of the pump.Both the pump head and the efficiency are reduced with increasing particle diameter or concentration.However,the effect of particle density on the performance is relatively minor.An obvious jet-wake flow structure is presented near the volute tongue and becomes more remarkable with increasing solid phase concentration.The suction side of the blade is subject to much more severe abrasion than the pressure side.The obtained results preliminarily reveal the characteristics of solid-liquid two-phase flow in the centrifugal pump,and are helpful for improvement and empirical correction in the hydraulic design of centrifugal pumps. | ZHANG Yuliang LI Yi CUI Baoling ZHU Zuchao DOU Huashu | 2013 | Chinese Journal of Mechanical Engineering2013，26，1： | 55 |

| 3 | Computational Analysis of Centrifugal Pump Delivering Solid-liquid Two-phase Flow during Startup Period显示文摘The transient behavior of centrifugal pumps during transient operating periods,such as startup and stopping,has drawn more and more attention recently because of urgent needs in engineering.Up to now,almost all the existing studies on this behavior are limited to using water as working fluid.The study on the transient behavior related to solid-liquid two-phase flow has not been seen yet.In order to explore the transient characteristics of a high specific-speed centrifugal pump during startup period delivering the pure water and solid-liquid two-phase flow,the transient flows inside the pump are numerically simulated using the dynamic mesh method.The variable rotational speed and flow rate with time obtained from experiment are best fitted as the function of time,and are written into computational fluid dynamics(CFD)code-FLUENT by using a user defined function.The predicted heads are compared with experimental results when pumping pure water.The results show that the difference in the transient performance during startup period is very obvious between water and solid-liquid two-phase flow during the later stage of startup process.Moreover,the time for the solid-liquid two-phase flow to achieve a stable condition is longer than that for water.The solid-liquid two-phase flow results in a higher impeller shaft power,a larger dynamic reaction force,a more violent fluctuation in pressure and a reduced stable pressure rise comparing with water.The research may be useful to understanding on the transient behavior of a centrifugal pump under a solid-liquid two-phase flow during startup period. | ZHANG Yuliang LI Yi ZHU Zuchao CUI Baoling | 2014 | Chinese Journal of Mechanical Engineering2014，27，1： | 13 |

| 5 | Experimental Study on a Centrifugal Pump with an Open Impeller during Startup Period显示文摘Transient performance of fluid machinery during transient operating periods,such as startup and stopping,has been drawn more attentions recently due to the growing engineering needs.In this paper,the transient behavior of a prototype centrifugal pump with an open impeller during rapid startup period is studied experimentally.The variations of the rotational speed,flow rate,head,and shaft power during rapid startup period are recorded in experiments at different discharge valve openings.In addition,the non-dimensional flow rate and head are also used to analyze the transient behavior.The research result shows that the rise characteristic of the rotational speed is not basically changed by working points,while mainly depends on the startup characteristics of the driving motor.Compared with the rapid rise of the rotational speed,the flow rate rises slowly in the initial stage of startup.Moreover,the flow rate lags behind the rotational speed to rise to final stable value,and the delay becomes more severe with the increase of the discharge valve opening.The shaft power impact phenomenon generally exists in the process of startup.The non-dimensional analysis shows that the non-dimensional head is very high at the very beginning of startup,and quickly falls to the minimum,then gradually rises to final stable value,while the non-dimensional flow rate always shows the rise tendency during whole startup period.In conclusion,it is found from the non-dimensional results that the quasi-steady analysis is unable to accurately assess the transient flow during startup period. | Yuliang Zhang Zuchao Zhu Yingzi Jin Baoling Cui Yi Li Huashu Dou | 2013 | Journal of Thermal Science2013，22，1： | 5 |
| 6 | Nano-bio interactions: the implication of size-dependent biological effects of nanomaterials显示文摘Due to their many advantageous properties,nanomaterials(NMs)have been utilized in diverse consumer goods,industrial products,and for therapeutic purposes.This situation leads to a constant risk of exposure and uptake by the human body,which are highly dependent on nanomaterial size.Consequently,an improved understanding of the interactions between different sizes of nanomaterials and biological systems is needed to design safer and more clinically relevant nano systems.We discuss the sizedependent effects of nanomaterials in living organisms.Upon entry into biological systems,nanomaterials can translocate biological barriers,distribute to various tissues and elicit different toxic effects on organs,based on their size and location.The association of nanomaterial size with physiological structures within organs determines the site of accumulation of nanoparticles.In general,nanomaterials smaller than 20 nm tend to accumulate in the kidney while nanomaterials between 20 and 100 nm preferentially deposit in the liver.After accumulating in organs,nanomaterials can induce inflammation,damage structural integrity and ultimately result in organ dysfunction,which helps better understand the size-dependent dynamic processes and toxicity of nanomaterials in organisms.The enhanced permeability and retention effect of nanomaterials and the utility of this phenomenon in tumor therapy are also highlighted. | Xiaoyu Wang Xuejing Cui Yuliang Zhao Chunying Chen | 2020 | Science China(Life Sciences)2020，63，8： | 4 |
| 7 | Heterogeneous Network-Based Chronic Disease Progression Mining显示文摘Healthcare insurance fraud has caused billions of dollars in losses in public healthcare funds around the world. In particular, healthcare insurance fraud in chronic diseases is especially rampant. Understanding disease progression can help investigators detect healthcare insurance frauds early on. Existing disease progression methods often ignore complex relations, such as the time-gap and pattern of disease occurrence. They also do not take into account the different medication stages of the same chronic disease, which is of great help when conducting healthcare insurance fraud detection and reducing healthcare costs. In this paper, we propose a heterogeneous network-based chronic disease progression mining method to improve the current understanding on the progression of chronic diseases, including orphan diseases. The method also considers the different medication stages of the same chronic disease. Extensive experiments show that our method can outperform the existing methods by 20% in terms of F-measure. | Chenfei Sun Qingzhong Li Lizhen Cui Hui Li Yuliang Shi | 2019 | Big Data Mining and Analytics2019，2，1： | 3 |
| 8 | Uptake of oxidative stress-mediated extracellular vesicles by vascular endothelial cells under low magnitude shear stress显示文摘Extracellular vesicles(EVs)are increasingly used as delivery vehicles for drugs and bioactive molecules,which usually require intravascular administration.The endothelial cells covering the inner surface of blood vessels are susceptible to the shear stress of blood flow.Few studies demonstrate the interplay of red blood cell-derived EVs(RBCEVs)and endothelial cells.Thus,the phagocytosis of EVs by vascular endothelial cells during blood flow needs to be elucidated.In this study,red blood cell-derived extracellular vesicles(RBCEVs)were constructed to investigate endothelial cell phagocytosis in vitro and animal models.Results showed that low magnitude shear stress including low shear stress(LSS)and oscillatory shear stress(OSS)could promote the uptake of RBCEVs by endothelial cells in vitro.In addition,in zebrafish and mouse models,RBCEVs tend to be internalized by endothelial cells under LSS or OSS.Moreover,RBCEVs are easily engulfed by endothelial cells in atherosclerotic plaques exposed to LSS or OSS.In terms of mechanism,oxidative stress induced by LSS is part of the reason for the increased uptake of endothelial cells.Overall,this study shows that vascular endothelial cells can easily engulf EVs in areas of low magnitude shear stress,which will provide a theoretical basis for the development and utilization of EVs-based nano-drug delivery systems in vivo. | Xian Qin Kun Zhang Juhui Qiu Nan Wang Kai Qu Yuliang Cui Junli Huang Li Luo Yuan Zhong Tian Tian Wei Wu Yi Wang Guixue Wang | 2022 | Bioactive Materials2022，7，3： | 3 |

| 15 | Assessment of Agricultural Drought Vulnerability Based on Crop Growth Stages:A Case Study of Huaibei Plain,China显示文摘Climate change can lead to and intensify drought disasters.Quantifying the vulnerability of disaster-affected elements is significant for understanding the mechanisms that transform drought intensity into eventual loss.This study proposed a growth-stage-based drought vulnerability index(GDVI)of soybean using meteorological,groundwater,land use,and field experiment data and crop growth model simulation.The CROPGRO-Soybean model was used to simulate crop growth and water deficit.Four growth stages were considered since the sensitivity of soybean to drought is strictly related to the growth stage.The GDVI was applied to the Huaibei Plain,Anhui Province,China,with the goal of quantifying the spatiotemporal characteristics of soybean drought vulnerability in typical years and growth stages.The results show that:(1)The sensitivity of leaf-related parameters exceeded that of other parameters during the vegetative growth stage,whereas the top weight and grain yield showed a higher sensitivity in the reproductive growth stage;(2)A semi-logarithmic law can describe the relationship between the drought sensitivity indicators and the GDVI during the four growth stages.The pod-filling phase is the most vulnerable stage for water deficit and with the highest loss upper limit(over 70%);(3)The 2001 and 2002 seasons were the driest time during 1997-2006.Fuyang and Huainan Cities were more vulnerable to drought than other regions on the Huaibei Plain in 2001,while Huaibei and Suzhou Cities were the most susceptible areas in 2002.The results could provide effective decision support for the categorization of areas vulnerable to droughts. | Yanqi Wei Juliang Jin Haichao Li Yuliang Zhou Yi Cui Nii Amarquaye Commey Yuliang Zhang Shangming Jiang | 2023 | International Journal of Disaster Risk Science2023，14，2： | 0 |

| 17 | Single-cell transcriptome analysis reveals a cancer-associated fibroblast marker gene signature in hepatocellular carcinoma that predicts prognosis显示文摘Background and aims:Hepatocellular carcinoma(HCC)is one of the leading causes of cancer death.Multi-pathway combination therapy is used to treat HCC,and immunotherapy is also a routine part of treatment.As a major component of the tumor microenvironment(TME),cancer-associated fibroblasts(CAFs)actively participate in cancer progression through complex functions.However,because CAFs dynamically change during cancer development,most of the current treatment strategies targeting CAFs fail.We created a prognostic CAF marker gene signature(CAFMGS)to investigate the utility of CAFs as a prognostic factor and therapeutic target.Methods:Gene Expression Omnibus(GEO)single-cell RNA sequencing(Sc-RNA-seq)data were analyzed to identify CAF marker genes in HCC.The Cancer Genome Atlas(TCGA)database was used as a training cohort to construct the CAFMGS model and the International Cancer Genome Consortium(ICGC)dataset was used to validate the CAFMGS.Results:Marker genes in the CAFMGS model were(0.0001-SPP1),(0.0084-VCX3A),(0.0015-HMGA1),(0.0082-PLOD2),and(0.0075-CACYBP).The CAFMGS_score was separated into high-risk and low-risk groups based on the median of the patients’OS.Univariate and multivariate analyses confirmed that CAFMGS_score was an independent prognostic factor in the training group.CAFMGS_score was a more accurate prognostic indicator compared with clinicopathological score and tumor mutational burden score.Conclusion:CAFMGS offers a fresh perspective on stromal cell marker genes in HCC prognosis and expands our knowledge of CAF heterogeneity and functional diversity,perhaps paving the way for CAF-targeted immunotherapy in HCC patients. | Hao Chi Dapeng Chen Yuliang Zhang Zilin Cui Yi Bai Yamin Zhang | 2023 | iLIVER2023，2，1： | 0 |

| 20 | Persistence of charge density wave against variation of band structures in V_(x)Ti_(1−x)Se_(2)(x=0–0.1)显示文摘Charge density wave(CDW)is a phenomenon that occurs in materials,accompanied by changes in their intrinsic electronic properties.The study of CDW and its modulation in materials holds tremendous significance in materials research,as it provides a unique approach to controlling the electronic properties of materials.TiSe_(2) is a typical layered material with a CDW phase at low temperatures.Through V substitution for Ti in TiSe_(2),we tuned the carrier concentration in V_(x)Ti_(1-x)Se_(2) to study how its electronic structures evolve.Angle-resolved photoemission spectroscopy(ARPES)shows that the band-folding effect is sustained with the doping level up to 10%,indicating the persistence of the CDW phase,even though the band structure is strikingly different from that of the parent compound TiSe_(2).Though CDW can induce the band fold effect with a driving force from the perspective of electronic systems,our studies suggest that this behavior could be maintained by lattice distortion of the CDW phase,even if band structures deviate from the electron-driven CDW scenario.Our work provides a constraint for understanding the CDW mechanism in TiSe_(2),and highlights the role of lattice distortion in the band-folding effect. | Zhanfeng Liu Tongrui Li Wen Zhu Hongwei Shou Mukhtar Lawan Adam Qilong Cui Yuliang Li Sheng Wang Yunbo Wu Hongen Zhu Yi Liu Shuangming Chen Xiaojun Wu Shengtao Cui Li Song Zhe Sun | 2024 | Nano Research2024，17，3： | 0 |
