Using SAS ® Clinical Data Integration to Roundtrip a Complete Study Study Metadata (Define-XML) and Study Data (Dataset-XML)
2015Co-Authors: Ken EllisAbstract:SAS Clinical Data Integration 2.6 now supports the complete CDISC Define-XML 2.0 specification for both import from, and creation of define.xml files. Support for value-level metadata and supplemental documents, as well as support for the new CDISC Dataset-XML specification have been added and give the user a powerful means by which to import and create complete study definitions. Topics covered include: import of CDISC Define-XML file metadata, including domains, value-level metadata, supplemental documents, computational algorithms and code lists import of accompanying domain data from CDISC Dataset-XML files creation of a complete CDISC Define-XML file including all imported metadata (Roundtrip) creation of CDISC Dataset-XML files from the imported domain tables (Roundtrip)

Film growth of c-axis parallel oriented ZnO on entire surface of silica glass pipe for SH-SAW pipe sensor
2017 IEEE International Ultrasonics Symposium (IUS), 2017Co-Authors: Yuta Takamura, Shinji Takayanagi, Chizu Ishida, Mami Matsukawa, Takahiko YanagitaniAbstract:SH-SAW is suitable for liquid sensors to measure conductivity and viscosity because it can propagate without the energy leakage into liquid. We have fabricated a SH-SAW sensor consisting of a c-axis parallel (11–20) oriented ZnO film on a silica glass plate [1]. On the other hand, the long-distance propagation is necessary in order to detect the small changes of the velocity and amplitude. One way to increase propagation distance is wave multiple Roundtrips around the sensor. In previous study, the c-axis parallel oriented ZnO film was grown on a part of the glass pipe surface and the SH-BAW Roundtrips were demonstrated [2]. However, the SH-SAW Roundtrips were not observed because the ZnO film was not grown on the entire surface of the pipe. In this study, we demonstrated the entirepipe-surface deposition of c-axis parallel oriented ZnO film to obtain SH-SAW pipe sensor.

liquid loading characteristics of multiple sh wave Roundtrip in c axis parallel oriented zno film silica glass pipe
Journal of the Acoustical Society of America, 2016Co-Authors: Shinji Takayanagi, Shoko Hiyama, Mami Matsukawa, Takahiko YanagitaniAbstract:Shear waves with in-plane displacement are suitable for liquid sensors because they can propagate without the energy leakage into liquid. In previous study, we have demonstrated the SH-SAW excitation with (11-20) oriented ZnO film whose c-axis is parallel to the substrate plane [1]. For a high sensitive sensor, the long propagation path is needed to detect small changes of the velocity and amplitude. Multiple wave Roundtrips on a pipe surface realizes the long propagation path. In this study, we fabricated IDT/c-axis parallel oriented ZnO film/silica glass pipe structure. The fourth Roundtrip was observed by the time response measurement using a network analyzer. The insertion loss of the first lap consisted of two frequency components at 131 MHz and 160-350 MHz. We also measured the liquid loading characteristics by immersing the inside pipe surface. Compared with the unloaded characteristics, insertion losses with pure water increased 0.6 dB at 131 MHz and 1.1 dB at 236 MHz. Because of small increases i...

Multiple shear wave Roundtrips liquid sensor by c-axis parallel oriented ZnO film/silica glass pipe structure
2014 IEEE International Ultrasonics Symposium, 2014Co-Authors: Shoko Hiyama, Shinji Takayanagi, Takahiko Yanagitani, Yoshiya Kato, Mami MatsukawaAbstract:We demonstrated the multiple Roundtrips of shear horizontal (SH) waves using IDT/c-axis parallel-oriented (1120) ZnO film/silica glass pipe structure for a high-sensitive liquid sensor. Forth Roundtrip was observed in the time response of acoustic waves. The insertion loss of the first lap consisted of two frequency components at 131 MHz and 160–350 MHz. IDT/c-axis parallel-oriented ZnO film/silica glass cylinder structure was also fabricated, but multiple Roundtrips were not occurred. Therefore, we considered the waves propagating in the pipe structure as plate type waves, not surface acoustic waves. In addition, the liquid loading characteristics of the pipe structure sensor were measured by immersing inside or outside of the pipe in liquid. Because the insertion loss increases in the pipe structure with pure water loading were relatively small, we can conclude that the waves were SH-type plate wave. Liquid property detections using both outside and inside of the pipe structure sensor are expected.

Observation of Duration-Tunable Soliton Explosion in Passively Mode-Locked Fiber Laser
IEEE Photonics Journal, 2017Co-Authors: Pan Wang, Xiaosheng Xiao, Hang Zhao, Changxi YangAbstract:We report on the first observation, to the best of our knowledge, of soliton explosions in an ultrafast fiber laser mode-locked by nonlinear polarization evolution. The soliton explosion is a transition state between stable mode-locking and noise-like pulses regimes. By tuning the waveplates and the spectral filter, the duration of soliton explosions is widely tunable from ∼100 Roundtrips to thousands of Roundtrips. Our experimental results together with the numerical simulations reveal the dissipative nature of soliton explosions, and may be beneficial for further understanding of this striking phenomenon.
