Ureteral stricture caused by holmium: YAG laser lithotripsy is one of the most challenging issues for urologists. Currently, evidence rapamycin application in reducing ureterostenosis not sufficient. This study aimed to assess inhibition ureteral rapamycin-eluting stents vitro and vivo. A bilayered drug-eluting stent consisted drug blending with poly (lactic-co-glycolic acid) (PU/drug stent), which was over-layered polycaprolactone (PCL) ultrasonic atomizing spraying. Stent morphology...

We have investigated the hydride vapor-phase epitaxy growth of -oriented GaN thick films on patterned sapphire substrates (PSSs) . From characterization by atomic force microscopy, scanning electron double-crystal X-ray diffraction, and photoluminescence (PL), it is determined that crystalline optical qualities epilayers grown cylindrical PSS are better than those flat sapphire. However, two main orientations dominate pyramidal PSS, demonstrating poor quality. After etching in mixed acids,...

We present experimental and theoretical results for electron-impact-induced ionization excitation of helium atoms. Using a high-sensitivity high-resolution $(e,2e)$ spectrometer, we measured the differential cross sections ionization-excitation He to $n=1\ensuremath{-}5$ states ${\mathrm{He}}^{+}$ at an impact energy 600 eV. The are compared with 4-body distorted wave (4DW) calculations first Born approximation (FBA) calculations. It was found that 4DW can well describe shapes simultaneous...

We present experimental and theoretical results for electron-impact-induced ionization excitation of the neon valence shell by using a highly sensitive high-resolution ($e, 2e$) spectrometer. The controversies in previous electron momentum spectroscopic have been resolved. satellites at 55.83 71.50 eV are mainly attributed to ${\phantom{\rule{4pt}{0ex}}}^{2}P$ manifold, mixed up with some ${}^{2}S$, not pure ${}^{2}S$ as were assigned earlier electron-momentum spectroscopy. Our distribution...

The photoionization cross-sections of Ti2+ in the ground state ([Ne]3s23p63d23Fe) are calculated using both non-relativistic (LS-coupling) and relativistic (Breit–Pauli) R-matrix methods for photon energy from 27.49 eV (I.P.) to 48.00 eV. results show that, this range, dominated by resonances 3p53d3, 3p53d24d 3p53d24s, which labelled LS-terms combining with multiconfiguration Dirac-Fock calculations. Moreover, fractional parentage coefficients percentages (the square configuration...

The combination of a 3He proportional counter and 4He sharing the same parameters was employed as low background thermal neutron detector. wall material is oxygen-free copper for surface emit rate. Other characters including effect energy resolution were also optimized performance. A portable readout electronics system has been developed output charge sensitive preamplifier directly digitized offline analysis. risetime from 10% to 60% selected estimation electron delay time which proves be...

Infrared absorption in GaAs∕AlxGa1−xAs multiple quantum wells is investigated using a polarizer. Two main peaks, with wave numbers 723 and 1092cm−1, are observed. The peak number 1092cm−1 corresponds to the 0→1 intersubband transition, while other one intrasubband transition. polarized absorbance order of magnitude higher than unpolarized one. authors attribute transition plasma oscillation wells.
