  • Retrieval of frequency spectrum from time-resolved spectroscopic data:comparison of Fourier transform and linear prediction methods

    Article English OPEN
    Eom, Intae; Yoon, Eunjin; Baik, Sung-Hoon; Lim, Yong-Sik; Joo, Taiha;
    (2014)
    Femtosecond time-resolved signals often display oscillations arising from the nuclear and electronic wave packet motions. Fourier power spectrum is generally used to retrieve the frequency spectrum. We have shown by numerical simulations and coherent phonon spectrum of ...

  • DNA binding fluorescent proteins for the direct visualization of largeDNA molecules

    Article English OPEN
    Lee, Seonghyun; Oh, Yeeun; Lee, Jungyoon; Choe, Sojeong; Lim, Sangyong; Lee, Hyun Soo; Jo, Kyubong; Schwartz, David C.;
    (2016)
    Fluorescent proteins that also bind DNA molecules are useful reagents for a broad range of biological applications because they can be optically localized and tracked within cells, or provide versatile labels for in vitro experiments. We report a novel design for a fluo...

  • Gold nanozyme-based paper chip for colorimetric detection of mercuryions

    Article English OPEN
    Han, Kwi Nam; Choi, Jong-Soon; Kwon, Joseph;
    (2017)
    In this study, we developed a facile gold nanozyme-based paper chip (AuNZ-PAD) for Hg2+ detection. This device has the advantages of being simple, rapid, cost effective, sensitive, selective, high throughput, and applicable to onsite detection. The colorimetric mercury ...

  • Speckle statistics and transverse coherence of an x-ray laser withfluctuations in its active medium

    Article English OPEN
    Janulewicz, K. A.; Kim, C. M.; Stiel, H.;
    (2013)
    It is shown that the statistics of the intensity distribution in the output beam of a collisional X-ray laser, analysed in terms of the degree of freedom or equivalently the number of the coherence modes in the beam cross-section, has non-Gaussian character. The non-Gau...

  • Optimal Energy Scheduling and Transaction Mechanism for MultipleMicrogrids

    Article English OPEN
    Kim, Boram; Bae, Sunghwan; Kim, Hongseok;
    (2017)
    In this paper, we propose a framework for optimal energy scheduling combined with a transaction mechanism to enable multiple microgrids to exchange their energy surplus/deficit with others while the distributed networks of microgrids remain secure. Our framework is base...

  • Eco-friendly graphene synthesis on Cu foil electroplated by reusing Cuetchants

    Article English OPEN
    Kwon, Ki Chang; Ham, Juyoung; Kim, Sungjun; Lee, Jong-Lam; Kim, Soo Young;
    (2014)
    Graphene film grown by chemical vapor deposition using Cu substrate is promising for industrial applications. After etching the Cu substrate, which is essential step in graphene transfer process, the etchant solution must be chemically treated to prevent water pollution...

  • Anti-septic activity of alpha-cubebenoate isolated from Schisandrachinensis

    Article English OPEN
    Kook, Minsoo; Lee, Sung Kyun; Kim, Sang Doo; Lee, Ha Young; Hwang, Jae Sam; Choi, Young Whan; Bae, Yoe-Sik;
    (2015)
    Sepsis is a life-threatening, infectious, systemic inflammatory disease. In this study, we investigated the therapeutic effect of alpha-cubebenoate, a novel compound isolated from Schisandra chinensis against polymicrobial sepsis in a cecal ligation and puncture (CLP) e...

  • Adsorptive Removal of Carbamazepine and Diatrizoate in Iron OxideNanoparticles Amended Sand Column Mimicing Managed Aquifer Recharge

    Article English OPEN
    Yoon, Soon Uk; Mahanty, Biswanath; Kim, Chang Gyun;
    (2017)
    The sorption-desorption of recalcitrant pharmaceuticals in sand/soil columns can be used to infer performance of managed aquifer recharge. Removal of carbamazepine (CBZ) and diatrizoate (DTZ) from synthetic wastewater, containing 100 mu g.L-1 of each pharmaceuticals, wa...

  • The use of statins for the treatment of depression in patients withacute coronary syndrome

    Article English OPEN
    Kim, S. W.; Bae, K. Y.; Kim, J. M.; Shin, I. S.; Hong, Y. J.; Ahn, Y.; Jeong, M. H.; Berk, M.; Yoon, J. S.;
    (2015)
    This study aimed to investigate the effect of statins for the treatment of depression in individuals with acute coronary syndrome (ACS). We used 1-year follow-up data of a 24-week double-blind, placebo-controlled trial of escitalopram and a naturalistic prospective obse...

  • Solution-Processed Vertically Stacked Complementary Organic Circuitswith Inkjet-Printed Routing

    Article English OPEN
    Kwon, Jimin; Kyung, Sujeong; Yoon, Sejung; Kim, Jae-Joon; Jung, Sungjune;
    (2016)
    The fabrication and measurements of solution-processed vertically stacked complementary organic field-effect transistors (FETs) with a high static noise margin (SNM) are reported. In the device structure, a bottom-gate p-type organic FET (PFET) is vertically integrated ...
