Higher order mode supercontinuum generation in tantalum pentoxide (TaO) channel waveguide.

We fabricated tantalum pentoxide (TaO) channel waveguides and used them to experimentally demonstrate higher-order mode supercontinuum (SC) generation. The TaO waveguide has a high nonlinear refractive index which was in an order magnitude of 10 cm/W and was designed to be anomalously dispersive at the pumping wavelength. To the best of our knowledge, this is the first time a higher-order mode femtosecond pump based broadband SC has been measured from a nonlinear waveguide using the phase-matching method.

Evaluation of intraoperative radiotherapy for gastric carcinoma with D2 and D3 surgical resection.

Aim: To study the proper sites and doses of intraoperative radiotherapy (IORT) for gastric carcinoma and the effects of this treatment.

Methods: A total of 106 patients with stage I-IV gastric carcinoma who received D2 or D3 radical operation combined with IORT were analyzed. Sixty-seven patients with gastric cancer of the antrum and body underwent distal gastrectomy.
