  4. Gastric pull-up reconstruction combined with free jejunal transfer (FJT) following total pharyngolaryngo-oesophagectomy (PLE).

    International Journal of Surgery 18:95 (2015) PMID 25865081

    Reconstruction following total pharyngolaryngo-oesophagectomy (PLE) still challenges surgeons because of the extreme length of removed tissue. Gastric pull-up reconstruction, one of the most common reconstructive methods after PLE, has many complications such as anastomotic fistula and gastric n...
  5. Locked Posterior Shoulder Dislocation Associated With Isolated Fractures of the Lesser Tuberosity: A Clinical Study of 22 Cases With a Minimum of 2-Year Follow-up.

    To evaluate the clinical and radiographic outcomes of 2-part lesser tuberosity fracture with a locked posterior dislocation. Retrospective case series study. Beijing Jishuitan Hospital ("first-level teaching hospital"). Between April 2003 and June 2010, 29 patients received surgical treatment fo...
  6. Ultrathin dual-mode filtering characteristics of terahertz metamaterials with electrically unconnected and connected U-shaped resonators array

    Optics Communications 342:20 (2015)

    We experimentally and numerically demonstrate dual-mode resonances of electrically unconnected and connected U-shaped resonators array on flexible polyimide substrate in terahertz (THz) region. The unit cell consisting of two back-to-back U-shaped resonators (TUR) shows strong inductio...

  8. A Massive Expansion of Effector Genes Underlies Gall-Formation in the Wheat Pest Mayetiola destructor

    Current Biology 25(5):613 (2015) PMID 25660540

    Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our understanding of ecology and adaptive radiation [2]. However, the mec...

  10. Influence of spatial incident angles on polarizer with a slit in grooved metal slabs for terahertz communication.

    Applied Optics 54(6):1363 (2015) PMID 25968200

    We report the influence of two spatial incident angles on a terahertz polarizer, which is based on an aluminum slab with a center slit flanked by symmetrically distributed parallel grooves on both sides. Experimental results show that the polarizer shows narrow bandpass filtering effect with a v...
  11. Ultra-broadband terahertz perfect absorber by exciting multi-order diffractions in a double-layered grating structure.

    Optics Express 23(3):2032 (2015) PMID 25836074

    Terahertz (THz) perfect absorber, as a useful functional device, has attracted considerable attention. Traditional metamaterial perfect absorbers are usually in response to single-frequency or multi-frequency owing to the resonance features of the metal-based sub-wavelength structure. In this pa...
