| 1 | Prevention strategies for ureteral stricture following ureteroscopic lithotripsy显示文摘Ureteral stricture formation after ureteroscopic lithotripsy is a late complication that can lead to hydronephrosis and a subsequent risk of renal deterioration.The specific incidence is unknown,and the mechanism of stricture formation has not been completely explained.In this review,we summarize the current evidence regarding the incidence of this condition and discuss its pathogenesis.We then list preventive strategies to reduce the morbidity of ureteral strictures。 | Hao Dong Yonghan Peng Ling Li Xiaofeng Gao | 2018 | Asian Journal of Urology2018，5，2： | 18 |

| 3 | Optimization based scheduling for a class of production systems with integral constraints显示文摘Operation scheduling for a class of production systems with'instantly consumed'products is very important.It is challenging to satisfy the real time system demand and to consider the realizability of the production schedules.This paper formulates a new model for optimization based production scheduling problems with integral constraints.Based on the detailed analysis of the production rate constraints,it is proved that this type of optimization problems is equivalent to a smooth nonlinear programming problem.The reachable upper and lower bounds of the production amount in every period can be expressed as functions of two variables,i.e.,the production rate at the start and end of that period.It is also proved that the gradients of these functions are monotonic,and their convexity or concavity is guaranteed.When the production cost function is convex,this type of optimization problems is equivalent to a convex programming problem.With the above analysis,a two-stage solution method is developed to solve the production scheduling problems with integral constraints,and in many applications the global optimal solution can be obtained efficiently.With the new model and solution method,the difficulties caused by the constraints on production rate can be overcome and the optimal schedule can be obtained with the real time system demand satisfied.Numerical testing for scheduling of electric power production systems is performed and the testing results are discussed.It is demonstrated that the new model and solution method are effective. | GUAN XiaoHong ZHAI QiaoZhu FENG YongHan GAO Feng | 2009 | Science China(Technological Sciences)2009，52，12： | 5 |
| 4 | Surgical management of esophageal strictures after caustic bums:A 30 years of experience显示文摘AIM: To analyze a 30-year historical series of patients treated in our hospital, who ingested corrosive substances, and to assess the effectiveness of surgical therapy administered in patients with strictures after caustic injury in esophagus during this period.METHODS: A total of 79 cases of caustic burns in esophagus were treated in Tangdu Hospital from 1971 to 2001. Their clinical and pathological data were reviewed, and collected from the medical records of patients and interviews with them.RESULTS: More men (n = 61) than women (n = 18) ingested caustic substances with a sex ratio of 3.4:1 during the30-year period. The caustic materials were liquid lye and acids (54 cases and 25 cases, respectively). Sixty-eight patients were given esophageal replacement in more than three months after caustic injury with no postoperative death, of which 17 cases developed postoperative complications making a complication rate of 25%. The most common one was cervical anastomotic leakage. All patients had improvement in swallowing afterwards. CONCLUSION: The presence and severity of injuries are correlated with the amount of caustic substances ingested. Surgical treatment is a good option in patients with severe strictures, and colonic interposition might be the best surgical process. The most important factors to guarantee a successful outcome for surgery are good vascular supply and absence of tension in the anastomosis. | YongHan Qing-ShuCheng Xiao-FeiLi Xiao-PingWang | 2004 | World Journal of Gastroenterology2004，10，19： | 3 |
| 5 | Characteristics and Nonlinear Growth of the Singular Vector Related to a Heavy Rainfall Case over the Korean Peninsula显示文摘In this study,singular vectors related to a heavy rainfall case over the Korean Peninsula were calculated using the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) adjoint modeling system.Tangent linear and adjoint models include moist physical processes,and a moist basic state and a moist total energy norm were used for the singular-vector calculations.The characteristics and nonlinear growth of the first singular vector were analyzed,focusing on the relationship between the basic state and the singular vector.The horizontal distribution of the initial singular vector was closely related to the baroclinicity index and the moisture availability of the basic state.The temperature-component energy at a lower level was dominant at the initial time,and the kinetic energy at upper levels became dominant at the final time in the energy profile of the singular vector.The nonlinear growth of the singular vector appropriately reflects the temporal variations in the basic state.The moisture-component energy at lower levels was dominant at earlier times,indicating continuous moisture transport in the basic state.There were a large amount of precipitation and corresponding latent heat release after that period because the continuous moisture transport created favorable conditions for both convective and nonconvective precipitation.The vertical propagation of the singular-vector energy was caused by precipitation and the corresponding latent heating in the basic state. | Yonghan CHOI Joowan KIM Dong-Kyou LEE | 2012 | Advances in Atmospheric Sciences2012，29，1： | 2 |
| 6 | Radar Data Assimilation for the Simulation of Mesoscale Convective Systems显示文摘A heavy rainfall case related to Mesoscale Convective Systems (MCSs) over the Korean Peninsula was selected to investigate the impact of radar data assimilation on a heavy rainfall forecast. The Weather Research and Forecasting (WRF) three-dimensional variational (3DVAR) data assimilation system with tuning of the length scale of the background error covariance and observation error parameters was used to assimilate radar radial velocity and reffectivity data. The radar data used in the assimilation experiments were preprocessed using quality-control procedures and interpolated/thinned into Cartesian coordinates by the SPRINT/CEDRIC packages. Sensitivity experiments were carried out in order to determine the optimal values of the assimilation window length and the update frequency used for the rapid update cycle and incremental analysis update experiments. The assimilation of radar data has a positive influence on the heavy rainfall forecast. Quantitative features of the heavy rainfall case, such as the maximum rainfall amount and Root Mean Squared Differences (RMSDs) of zonal/meridional wind components, were improved by tuning of the length scale and observation error parameters. Qualitative features of the case, such as the maximum rainfall position and time series of hourly rainfall, were enhanced by an incremental analysis update technique. The positive effects of the radar data assimilation and the tuning of the length scale and observation error parameters were clearly shown by the 3DVAR increment. | Jo-Han LEE Hyun-Ha LEE Yonghan CHOI Hyung-Woo KIM Dong-Kyou LEE | 2010 | Advances in Atmospheric Sciences2010，27，5： | 2 |
