    Conformable ultrasound breast patch for deep tissue scanning and imaging by Du, Wenya, Zhang, Lin, Suh, Emma, Lin, Dabin, Marcus, Colin, Ozkan, Lara, Ahuja, Avani, Fernandez, Sara, Shuvo, Ikra Iftekhar, Sadat, David, Liu, Weiguo, Li, Fei, Chandrakasan, Anantha P., Ozmen, Tolga, Dagdeviren, Canan

    Published 2024
    “…The in vitro studies and clinical trials reveal that the array using a piezoelectric crystal [Yb/Bi-Pb(In <jats:sub>1</jats:sub> <jats:sub>/2</jats:sub> Nb <jats:sub>1/2</jats:sub> )O <jats:sub>3</jats:sub> -Pb(Mg <jats:sub>1/</jats:sub> <jats:sub>3</jats:sub> Nb <jats:sub>2/3</jats:sub> )O <jats:sub>3</jats:sub> -PbTiO <jats:sub>3</jats:sub> ] (Yb/Bi-PIN-PMN-PT) exhibits a sufficient contrast resolution (~3 dB) and axial/lateral resolutions of 0.25/1.0 mm at 30 mm depth, allowing the observation of small cysts (~0.3 cm) in the breast. …”

    Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging by Du, Wenya

    Published 2024
    “…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”

    China's rural migrant workers and labour politics by Chan, J, Selden, M

    Published 2016
    “…As Ching Kwan Lee and Yuan Shen (2009: 110) demonstrate, under dual pressure from the state and academic institutions, many scholars who study workers in post-Cultural Revolution China ‘shun class analysis and define away labour issues as those of mobility, migration, and stratification’. …”

    Local-flexural interactive buckling of S690 high strength steel slender welded I-section columns: testing, modelling and design by Sun, Yao, Liang, Yating, Su, Andi, Zhao, Ou

    Published 2022
    “…A testing programme, adopting two S690 high strength steel slender welded I-sections, was firstly conducted and included initial geometric imperfection measurements and ten pin-ended column tests. The testing programme was accompanied by a numerical modelling programme, where finite element models were developed and validated against the test results and then employed to perform parametric studies to generate further numerical data over a wide range of cross-section dimensions and member effective lengths. …”
