| 1 | 不同含水状态下基床级配碎石填料变形特性研究显示文摘基床级配碎石在外界雨水侵入时含水状态发生改变对其变形特性不利,从而影响行车安全,但目前研究含水率对基床级配碎石变形特性的成果甚少,为进一步揭示不同含水状态下基床级配碎石的变形特性,对不同含水率的级配碎石试样开展了多组大型静动三轴试验。首先,通过静三轴试验探讨了含水率对级配碎石应力-应变关系和强度特性的影响;然后,基于动三轴试验,重点研究了含水率、动应力水平对累积应变随荷载作用次数发展规律的影响;在此基础上,建立了综合考虑含水率、荷载作用次数、动应力水平相互耦合作用的累积应变预测模型。基于含水率为5.0%和7.3%的累积应变试验结果,确定了模型中的待定参数,通过含水率为8.6%的试验结果验证了其正确性和合理性,此模型不仅克服了不同动应力水平下累积应变计算模型的分散性,而且能够直观地体现出含水率对累积应变的影响。 | 刘宝 PHAM Duc Phong 苏谦 桂波 | 2016 | 岩土力学2016，37，5： | 10 |
| 2 | 不同含水状态级配碎石临界动应力及变形规律研究显示文摘为评估含水率变化对高速铁路无砟轨道基床表层级配碎石动力性能的影响,本文针对最优含水率和饱和含水率两种状态下级配碎石循环动力性能开展室内大型动三轴试验研究,分析级配碎石的临界动应力和累积变形特性。研究表明:累积变形与荷载作用次数、含水率关系密切,荷载作用次数超过10 000次后,含水率的影响逐渐显现,荷载作用次数达到20 000次时,饱和含水率的累积变形相对最优含水率增大70%;不同含水率级配碎石的衰减型和破坏型累积变形曲线可分别用Stewart模型和Monismith模型预测;级配碎石临界动应力随含水率增大而减小,随围压的增大线性增大,饱和含水状态对应的临界动应力较最优含水状态平均小13%。 | 刘宝 苏谦 PHAM Duc Phong 白皓 LAM Thi Huyen Hanh | 2016 | 铁道学报2016，38，6： | 10 |
| 3 | 越南红河流域沉积物的镜下碳屑分析实验室处理方法对比研究显示文摘本文设计4个不同的实验方法,以越南红河流域原始森林区、河漫滩区和水下三角洲区3个不同沉积环境下的9个样品为实验对象,对镜下碳屑不同的实验室处理方法进行对比研究,实验发现样品用六偏磷酸钠分散法(方法A)和盐酸分散法(方法B)处理后,镜下碳屑形态不易分辨,杂质多,而用氢氟酸处理法(方法C)和附加醋酸酐混合液处理法(方法D),镜下碳屑的形态清晰,杂质少,碳屑数量容易统计,但是方法D中利用醋酸酐与浓硫酸混合液去纤维素与染色过程会使纤维素碳化,结果显示碳屑浓度明显比用前3种方法处理的浓度高。以上实验结果表明方法C是最优的。另外,本研究在进行碳屑统计时,利用NIS-Elements Br 3.0软件的自动统计计数功能,不仅可以减小人为计数产生的误差,还可以实现碳屑的多参数统计,有利于古环境、古气候、古植被变化的多信息解译。 | 陆岸青 李珍 李杰 Xuan Phong Dang Eiji Matsumoto | 2009 | 第四纪研究2009，29，4： | 7 |
| 4 | 越南红河水下三角洲表层沉积物中有机物分布及来源分析显示文摘采用总有机碳(OC%)、总氮(TN%)、有机碳同位素组成(δ13C)以及木质素方法,对越南红河水下三角洲表层沉积物进行研究,结合粒度数据,分析其有机物分布以及来源。结果表明,红河口表层沉积物的(C/N)mol在2.7—18.7之间;有机碳(OC%)和总氮(TN%)在近岸粒径大的站位含量低,粒度小的站位含量高;δ13C(‰)在22.8—25.9之间;Λ8(mg/100mgOC)在0.2—4.9之间。使用简单二端元模型计算后发现陆源有机物在表层沉积物中占的比例在3.7%—89.5%,并且与粒径大小有关,粒径大陆源有机物比例低,粒径小陆源有机物比例高,说明水动力分选是控制陆源有机物分布的主要因素。C/V和S/V分别为0.29±0.13和0.87±0.18,表明该区域的陆源有机物来源于被子植物的草本和木本部分混合。V系列的酸醛比(Ad/Al)v在0.38—2.43之间,平均值为0.70,说明该区域陆源有机物经历了中等程度的降解。 | 李中乔 吴莹 李珍 宋兵 DANG Xuan Phong | 2013 | 海洋与湖沼2013，44，3： | 7 |
| 5 | 越南红河水下三角洲北区表层沉积物类型及分布特征初探显示文摘对2007年采自越南红河水下三角洲北区24个表层沉积物样品进行了粒度分析和粒度参数计算,初步探讨了该区沉积物的主要类型及分布特征。结果表明,越南红河水下三角洲北区的表层沉积物主要由粉砂组成(体积平均含量为54.35%),平均粒径为6φ。按Link沉积物命名法,该区沉积物主要类型有砂、砂质粉砂和黏土质粉砂。水平分布上,由西部的砂向东逐渐变为黏土质粉砂,呈现出由近岸三角洲前缘相的粗粒级沉积物逐渐向前三角洲-浅海相的细粒级沉积物变化的趋势。与前人研究成果对比发现,红河水下三角洲北区沉积物黏土的比例较1996年的比例明显增大,可能与海岸线近10a来总体上呈向陆迁移、水下三角洲沉积向岸蚀退以及纵向上水动力逐渐变弱有关。 | 宋兵 李珍 李杰 李贞 Xuan Phong Dang Eiji Matsumoto | 2009 | 海洋通报2009，28，6： | 5 |
| 6 | 拌和与成型温度对SMA-16混合料性能影响研究显示文摘为明确施工温度对SMA-16混合料路面性能的影响,并为SMA-16路面施工的合理拌和及碾压成型温度提供技术依据,研究不同温度条件下沥青与矿料的粘附性;同时拟定4个拌和温度、2个成型温度,研究不同温度条件下SMA-16混合料的毛体积密度、孔隙率、马歇尔稳定性、水稳定性和高低温性能的变化。结果表明:加热温度为170~185℃时玄武岩粗集料与SBS改性沥青的裹覆性最好;拌和温度对木质素纤维SMA混合料高温稳定性的影响比较大,对水稳定性和低温稳定性的影响不明显;拌和温度为175~185℃时,木质素纤维SMA混合料的高温稳定性、低温变形性能和水稳定性最好。 | 程培峰 NGUYEN Hoang Phong 郝中华 李吉庭 DANG Van Thanh | 2017 | 新型建筑材料2017，44，7： | 4 |

| 9 | Could wastewater analysis be a useful tool for China?——A review显示文摘Analysing wastewater samples is an innovative approach that overcomes many limitations of traditional surveys to identify and measure a range of chemicals that were consumed by or exposed to people living in a sewer catchment area. First conceptualised in 2001, much progress has been made to make wastewater analysis(WWA) a reliable and robust tool for measuring chemical consumption and/or exposure. At the moment, the most popular application of WWA, sometimes referred as sewage epidemiology, is to monitor the consumption of illicit drugs in communities around the globe, including China. The approach has been largely adopted by law enforcement agencies as a device to monitor the temporal and geographical patterns of drug consumption. In the future, the methodology can be extended to other chemicals including biomarkers of population health(e.g. environmental or oxidative stress biomarkers, lifestyle indicators or medications that are taken by different demographic groups) and pollutants that people are exposed to(e.g. polycyclic aromatic hydrocarbons,perfluorinated chemicals, and toxic pesticides). The extension of WWA to a huge range of chemicals may give rise to a field called sewage chemical-information mining(SCIM) with unexplored potentials. China has many densely populated cities with thousands of sewage treatment plants which are favourable for applying WWA/SCIM in order to help relevant authorities gather information about illicit drug consumption and population health status. However, there are some prerequisites and uncertainties of the methodology that should be addressed for SCIM to reach its full potential in China. | Jianfa Gao Jake O'Brien Foon Yin Lai Alexander L.N.van Nuijs Jun He Jochen F.Mueller Jingsha Xu Phong K.Thai | 2015 | Journal of Environmental Sciences2015，27，1： | 4 |

| 13 | Engineering osteoblastic metastases to delineate the adaptive response of androgen-deprived prostate cancer in the bone metastatic microenvironment显示文摘While stromal interactions are essential in cancer adaptation to hormonal therapies,the effects of bone stroma and androgen deprivation on cancer progression in bone are poorly understood.Here,we tissue-engineered and validated an in vitro microtissue model of osteoblastic bone metastases,and used it to study the effects of androgen deprivation in this microenvironment.The model was established by culturing primary human osteoprogenitor cells on melt electrowritten polymer scaffolds,leading to a mineralized osteoblast-derived microtissue containing,in a 3D setting,viable osteoblastic cells,osteocytic cells,and appropriate expression of osteoblast/osteocyte-derived mRNA and proteins,and mineral content.Direct co-culture of androgen receptordependent/ independent cell lines (LNCaP,C4-2B,and PC3) led cancer cells to display functional and molecular features as observed in vivo.Co-cultured cancer cells showed increased affinity to the microtissues,as a function of their bone metastatic potential.Cocultures led to alkaline phosphatase and collagen-I upregulation and sclerostin downregulation,consistent with the clinical marker profile of osteoblastic bone metastases.LNCaP showed a significant adaptive response under androgen deprivation in the microtissues,with the notable appearance of neuroendocrine transdifferentiation features and increased expression of related markers (dopa decarboxylase,enolase 2).Androgen deprivation affected the biology of the metastatic microenvironment with stronger upregulation of androgen receptor,alkaline phosphatase,and dopa decarboxylase,as seen in the transition towards resistance.The unique microtissues engineered here represent a substantial asset to determine the involvement of the human bone microenvironment in prostate cancer progression and response to a therapeutic context in this microenvironment. | Nathalie Bock Ali Shokoohmand Thomas Kryza Joan Rohl Jonelle Meijer Phong A.

| 19 | Locally weighted learning based hybrid intelligence models for groundwater potential mapping and modeling: A case study at Gia Lai province, Vietnam显示文摘The groundwater potential map is an important tool for a sustainable water management and land use planning,particularly for agricultural countries like Vietnam.In this article,we proposed new machine learning ensemble techniques namely AdaBoost ensemble(ABLWL),Bagging ensemble(BLWL),Multi Boost ensemble(MBLWL),Rotation Forest ensemble(RFLWL)with Locally Weighted Learning(LWL)algorithm as a base classifier to build the groundwater potential map of Gia Lai province in Vietnam.For this study,eleven conditioning factors(aspect,altitude,curvature,slope,Stream Transport Index(STI),Topographic Wetness Index(TWI),soil,geology,river density,rainfall,land-use)and 134 wells yield data was used to create training(70%)and testing(30%)datasets for the development and validation of the models.Several statistical indices were used namely Positive Predictive Value(PPV),Negative Predictive Value(NPV),Sensitivity(SST),Specificity(SPF),Accuracy(ACC),Kappa,and Receiver Operating Characteristics(ROC)curve to validate and compare performance of models.Results show that performance of all the models is good to very good(AUC:0.75 to 0.829)but the ABLWL model with AUC=0.89 is the best.All the models applied in this study can support decision-makers to streamline the management of the groundwater and to develop economy not only of specific territories but also in other regions across the world with minor changes of the input parameters. | Hoang Phan Hai Yen Binh Thai Pham Tran Van Phong Duong Hai Ha Romulus Costache Hiep Van Le Huu Duy Nguyen Mahdis Amiri Nguyen Van Tao Indra Prakash | 2021 | Geoscience Frontiers2021，12，5： | 1 |
