    Three essays on corporate finance by Fu, Kangkang

    Published 2016
    “…Moreover, from the principal customers’ perspective, a higher level of environmental risk lowers a supplier firm’s probability of being selected relative to its industry peers by its potential customer. Conditional on an ongoing relationship with principal customers, supplier firms with high environmental risk have lower sales to principal customers and shorter relationship durations. …”

    Health economic aspects of childhood excess weight by Onyimadu, O

    Published 2024
    “…My analyses of CPRD-HES data revealed that children living with overweight and obesity incurred significantly higher direct healthcare costs than their peers with a healthy weight. In comparison to children with healthy weight, those living with overweight generated additional costs of £133.93 and £66.32, on average, in the year preceding and following a BMI measurement, respectively, while children with obesity incurred additional costs of £115.47 and £154.51, on average, during the same periods. …”

    Programmable interfacial band configuration in WS2/Bi2O2Se heterojunctions by Zhang, Hanwen, Fu, Jianhui, Carvalho, Alexandra, Poh, Eng Tuan, Chung, Jing-Yang, Feng, Minjun, Chen, Yinzhu, Wang, Bo, Shang, Qiuyu, Yang, Hengxing, Zhang, Zheng, Lim, Sharon Xiaodai, Gao, Weibo, Gradečak, Silvija, Qiu, Cheng-Wei, Lu, Junpeng, He, Chunnian, Sum, Tze Chien, Sow, Chorng Haur

    Published 2024
    “…Using this material combination, we further design a sophisticated band architecture incorporating both type-I (WS2 straddles Bi2O2Se, fluorescence-quenched) and type-I (Bi2SeO5 straddles WS2, fluorescence-recovered) alignments in one sample through focused laser beam (FLB). By programming the FLB trajectory, we achieve a predesigned localized fluorescence micropattern on WS2 without changing its intrinsic atomic structure. …”

    Constructing 3D self-supporting surfaces with isotropic stress using 4D minimal hypersurfaces of revolution by Ma, Long, He, Ying, Sun, Qian, Zhou, Yuanfeng, Zhang, Caiming, Wang, Wenping

    Published 2021
    “…The existing thrust network analysis methods discretize both geometry and material by approximating the continuous stress field through uniaxial singular stresses, making them an ideal tool for analysis and design of beam structures. In contrast, our method works on piecewise linear surfaces with continuous material. …”

    Effect of geometric scaling on the microstructural development of selective laser melted metal parts by Ng, Angelin Shia Yin

    Published 2022
    “…This study discusses the effect of geometric scaling, delay time (i.e., the time it takes for the laser beam to jump from one scan vector to the adjacent scan vector, which is controlled by the jump speed), gas flow, and defocusing distance on microstructural development and mechanical properties of selective laser melted 316L stainless steel. 316L stainless steel has been used in various industries such as aerospace and petrochemical industries due to its superior properties such as very good corrosion resistance. …”

    On shear adhesion of adhesive fibrils by Linghu, Changhong, Du, Zihao, Sun, Yi, Chen, Weiqiu, Hsia, K. Jimmy

    Published 2024
    “…Our model reveals that, depending on the fibrillar aspect ratio, the adhesive fibril exhibits three distinct deformation regimes: thin film shearing, thick block shearing, and slender beam bending. The important parameters governing the shear adhesion of the lap shear system are the aspect ratio of fibrils, elastic moduli of the fibrils and substrates, while the Poisson's ratio of fibrils has no noticeable effect. …”
