| 1 | Arithmetic and Fourier transform for the PYXIS multi-resolution digital Earth model显示文摘This paper investigates a multi-resolution digital Earth model called PYXIS,which was developed by PYXIS Innovation Inc.The PYXIS hexagonal grids employ an efficient hierarchical labeling scheme for addressing pixels.We provide a recursive definition of the PYXIS grids,a systematic approach to the labeling,an algorithm to add PYXIS labels,and a discussion of the discrete Fourier transform on PYXIS grids. | A.Vince X.Zheng | 2009 | International Journal of Digital Earth2009，2，1： | 20 |
| 2 | Implantation of trabecular micro-bypass stent using a novel “landing strip” technique显示文摘AIM:To describe a novel technique of creating a landing strip within the trabecular meshwork to guide trabecular micro-bypass stent(iStent) implantation in patients who underwent phacoemulsification.METHODS:Thirty-four eyes from 30 patients who underwent i Stent implantation after phacoemulsification from May 2014 to February 2015 were included in our retrospective study. All iStents were implanted via the 'landing strip' technique. A 25-gauge microvitreoretinal blade was used to bisect the trabecular meshwork to less than 1 clock-hour, effectively creating a landing strip. The iStent applicator was pressed along the landing strip and then the stent was released into the trabecular meshwork. RESULTS:Of the 34 eyes with iStent implantation, 27(79.4%) eyes had primary open-angle glaucoma, 6(17.6%) eyes had pseudoexfoliation glaucoma, and 1(2.9%) eye had ocular hypertension. At 6-month follow-up(n=17), the mean number of hypotensive medications decreased from 2.2±1.2 at baseline to 0.8±1.3(P=0.05) and mean intraocular pressure decreased from 19.7±4.1 mm Hg at baseline to 16.7±2.1 mm Hg(P=0.58). Two eyes(5.9%) required subsequent trabeculectomy. CONCLUSION:The 'landing strip' technique appears to be an effective way to assist with iS tent implantation. | Cindy X.Zheng Marlene R.Moster Priyanka Gogte Yang Dai Remy S.Manzi Michael Waisbourd | 2017 | International Journal of Ophthalmology(English edition)2017，10，5： | 2 |

| 4 | Nano-phase transformation of composite precipitates in multicomponent Al-Mg-Si(-Sc)alloys显示文摘Sc-addition can significantly enhance the performance of the micro-alloyed Al-Mg-Si-Sc alloys.However,the mechanisms by which the Sc element modifies the microstructure of the alloys are still unknown in many cases.Here,using atomic-scale transmission electron microscopy and atomic-resolution spectroscopy,we have revealed the microstructural differences between two age-hardened Al-0.5Mg-0.4Si(wt.%)alloys with and without Sc-addition.The first significant effect of Sc-addition on the precipitation microstructure of the Al-Mg-Si-Sc alloy is that Sc-atoms may distribute at theβ'-precipitate/Al-matrix interface and therefore accelerate aging kinetics at the initial stage of hardening.The second significant effect of Sc-addition is that in the transition from theβ'-hardened peak-age stage to theβ′-hardened late stage,Sc-atoms can greatly improve the stability of transitionalβ'/B'/β′composite precipitates by entering the B'-substructures and/or locating at the precipitate/Al interfaces.As such Sc-atoms effectively suppressβ'toβ'transformation and cross-sectional coarsening of bothβ'and composite precipitates,leading to much finer precipitate needles with smaller diameter but much larger length,as compared with those precipitate needles formed in the alloy without Sc-addition.Hence,the alloy with Sc-addition exhibits a much better thermal stability than that without Sc. | S.B.Wang C.F.Pan B.Wei X.Zheng Y.X.Lai J.H.Chen | 2022 | Journal of Materials Science & Technology2022，，15： | 1 |
