AIM: To describe and evaluate a new ophthalmic endoscope surgical technique combined with phacoe-mulsification and intraocular lens (IOL) implantation to treat goniosynechialysis and manage primary angle-closure glaucoma (PACG). ·METHODS: Endoscope-assisted goniosynechialysis combined with phacoemulsification and IOL implantation was performed in 32 eyes of 29 patients with PACG. Regular follow-up was performed 1 week and 1 month, 3, and 6 months after surgery to assess complications, intraocular pressure (IOP), anterior chamber depth, visual acuity, and anterior chamber angle. ·RESULTS: Preoperative mean IOP was 24.88±7.22mmHg with pharmacological treatment, and was 13.70 ±4.02, 13.06 ±3.74, 14.29 ±4.70, and 14.33 ±5.01mmHg 1 week, 1 month, 3 months, and 6 months after surgery, respectively. The postoperative decrease in IOP was significant (P < 0.05). The rate for all eyes with IOP of 21mmHg or less was 93.8% (30 eyes) at the final visit without ocular hypotensive agents. The average preoperative anterior chamber depth was 1.60 ±0.64mm, and this value significantly increased to 2.72±0.62, 2.76±0.70, 2.73±0.68, and 2.74 ±0.71mm at 1 week, 1 month, 3 months, and 6 months, respectively. Visual acuity was improved in 28 eyes (87.5% ) at 6 months postoperatively. The anterior chamber angle had increased in 25 eyes (78.1% ) at the final visit; it was adhesive 90°-180° in 6 eyes, 180°-270° in only 1 eye. Two eyes exhibited minimal hyphema in the early postoperative period, but it could gradually be absorbed. Fibrinous reaction was observed in five eyes and spontaneously disappeared within 7 days. No shallow anterior chamber, iridodialysis, choroidal deta-chment, or malignant glaucoma was found in any ***:Endoscope-assisted goniosynechialysis combined with phacoemulsification and IOL implantation to manage PACG has several advantages, including optimized visualization, greater accuracy, and improved safety. Our results suggest that it has certain curative e

Open and dynamic environments lead to inher- ent uncertainty of Web service QoS （Quality of Service）, and the QoS-aware service selection problem can be looked upon as a decision problem under uncertainty. We use an empiri- cal distribution function to describe the uncertainty of scores obtained from historical transactions. We then propose an approach to discovering the admissible set of services in- cluding alternative services that are not dominated by any other alternatives according to the expected utility criterion. Stochastic dominance （SD） rules are used to compare two services with uncertain scores regardless of the distribution form of their uncertain scores. By using the properties of SD rules, an algorithm is developed to reduce the number of SD tests, by which the admissible services can be reported pro- gressively. We prove that the proposed algorithm can be run on partitioned or incremental alternative services. Moreover, we achieve some useful theoretical conclusions for correct pruning of unnecessary calculations and comparisons in each SD test, by which the efficiency of the SD tests can be im- proved. We make a comprehensive experimental study using real datasets to evaluate the effectiveness, efficiency, and scal- ability of the proposed algorithm.

The southern coast of the Gulf of Maine in the United States is prone to flooding caused by nor＇easters. A state-of-the-art fully-coupled model, the Simulating WAves Nearshore （SWAN） model with unstructured grids and the ADvanced CIRCulation （ADCIRC） model, was used to study the hydrodynamic response in the Gulf of Maine during the Patriot＇s Day storm of 2007, a notable example of nor＇easters in this area. The model predictions agree well with the observed tide-surges and waves during this storm event. Waves and circulation in the Gulf of Maine were analyzed. The Georges Bank plays an important role in dissipating wave energy through the bottom friction when waves propagate over the bank from offshore to the inner gulf due to its shallow bathymetry. Wave energy dissipation results in decreasing significant wave height （SWH） in the cross-bank direction and wave radiation stress gradient, which in turn induces changes in currents. While the tidal currents are dominant over the Georges Bank and in the Bay of Fundy, the residual currents generated by the meteorological forcing and waves are significant over the Georges Bank and in the coastal area and can reach 0.3 m/s and 0.2 m/s, respectively. In the vicinity of the coast, the longshore current generated by the surface wind stress and wave radiation stress acting parallel to the coastline is inversely proportional to the water depth and will eventually be limited by the bottom friction. The storm surge level reaches 0.8 m along the western periphery of the Gulf of Maine while the wave set-up due to radiation stress variation reaches 0.2 m. Therefore, it is significant to coastal flooding.

We investigate the influence of the Stark shift on the entanglement transfer from the two-mode squeezed vacuum state field to two spatially separated atoms in two-photon processes. Our results show that the Stark shift plays an important role in such entanglement transfer. We find that when the Stark shift parameter r is small, the degree of entanglement between the two atoms increases with the increasing of the squeezing parameter ξ first, and after achieving its maximal value, the degree of entanglement will decrease to zero with the increasing of ξ; while for big r, E will increase with the increasing of ξ.

As promising approaches in wastewater treatment, advanced oxidation processes(AOPs) can efficiently degrade and mineralize the organic wastes and contaminants by generating reactive radicals like ·OH, ·SO_(4)^(-), and ·O_(2)^(-). However, due to the stronger oxidability, these reactive radicals exhibit lower selectivity of degradation.
