Asian Journal of Urology 2020年第4期7卷 376-378页

作者： Joshua A.Halpern Arighno Das robert e.brannigan Department of Urology Northwestern University Feinberg School of MedicineChicagoILUSA

Dear editor,eagle-Barrett or prune belly syndrome(PBS)is a rare congenital condition with an estimated incidence of 3.8 cases per 100000 live births in the United States[1].The syndrome is characterized by cryptorchidism,upper and lower urinary tract dilation,and either absence or deficiency of the abdominal wall *** much of the literature has focused upon urinary tract malformation and cryptorchidism,fertility is a crucial aspect of urologic evaluation and care in these patients.

A Cost-effective Flood Warning System for Small Urban Basins

引用

Journal of earth Science 2025年第1期36卷 307-313页

作者： robert e.Criss eric M.Stein Department of earth and Planetary Sciences Washington UniversitySt.Louis MO 63130USA

An effective warning system for flash floods along the upper River des Peres, a small urban stream in eastern Missouri, USA, is based on three enterprise-level, automated rain *** floods in this 25 km~2 basin develop rapidly and are commonly caused by small but intense thunderstorm cells, these rain gauges were necessarily deployed within the watershed, and immediate telemetry and processing of rainfall delivered in 5-minute intervals is required. Available data show that damaging floods in this area occur only 30 min to 3 h following the delivery of 38 mm of rainfall or more in a single hour. Water levels along this stream can rise more than 3 m/h. Since full deployment in Nov. 2021, our system has successfully predicted 3 significant floods with one false positive.

Statistics of evolving Populations and Their Relevance to Flood Risk

引用

Journal of earth Science 2016年第1期27卷 2-8页

作者： robert e.Criss Department of earth and Planetary Sciences Washington University in St.Louis

Statistical methods are commonly used to evaluate natural populations and environmental variables, yet these must recognize temporal trends in population character to be appropriate in an evolving world. New equations presented here define the statistical measures of aggregate historical populations affected by linear changes in population means and standard deviations. These can be used to extract the statistical character of present-day populations, needed to define modern variability and risk, from tables of historical data that are dominated by measurements made when conditions were different. As an example, many factors such as climate change and in-channel structures are causing flood levels to rise, so realistic estimation of future flood levels must take such secular changes into account. The new equations provide estimates of water levels for ＂100-year＂ floods in the USA Midwest that are 0.5 to 2 m higher than official calculations that routinely assume population stationarity. These equations also show that flood levels will continue to rise by several centimeters per year. This rate is nearly ten times faster than the rise of sea level, and thus represents one of the fastest and most damaging rates of change that is documented by robust data.

“采用数据驱动方法对受内压作用的受腐蚀管线断裂强度预报研究”讨论（英文）

引用

Journal of Marine Science and Application 2025年第01期 249-251页

作者： Mojtaba Mokhtari robert e.Melchers Centre for Autonomous Marine Operations and Systems Department of Marine TechnologyNorwegian University of Science and Technology(NTNU) Centre for Infrastructure Performance and Reliability The University of Newcastle

The authors(Cai et al., 2022) claim that their proposed machine learning(ML) models, which are based on three typical ML algorithms and are trained to predict the burst capacity of pitting corroded pipelines, perform better than the existing semi-empirical formulas recommended by the international engineering code developers, DNV and ASMe. The authors' assessments of the semi-empirical burst capacity formulas in Figure 10(a) and Table 8(Cai et al., 2022) incorrectly indicate that DNVGL-RPF101, ASMe B31G, and modified ASMe B31G are dangerously unsafe due to significantly overestimating burst pressures in several cases. In contrast to the results and conclusions in Cai et al.(2022), these semi-empirical formulas have been consistently found to be conservative(Benjamin et al., 2000; Benjamin et al., 2002; Chena et al., 2015; Cronin and Pick, 2000; Kiefner and Vieth, 1989;Mokhtari and Melchers, 2016; 2018; 2019; Netto et al., 2005; Teixeira et al., 2008; Yeom et al., 2015; Zhou and Huang, 2012), and have been safely implemented in the oil/gas industry for many years. The main cause of the contradiction between the authors' claims and well-established practical applications and results lies in the data upon which the study(Cai et al., 2022) is based, along with the authors' misinterpretation of the semi-empirical formulas. These points are elaborated below.

Use of Geochemical and Geophysical Techniques to Characterize and Prospect for Geothermal Resources and Hydrothermal Ore Deposits

引用

Journal of earth Science 2015年第1期26卷 73-77页

作者： robert e.Criss Department of earth and Planetary Sciences Washington UniversitySt.Louis 63130USA

Fluid-rock interactions alter the geochemical, isotopic, petrographic and physical character of host rocks, producing a permanent record of hydrothermal activity. Maps of altered rock properties show regular variations that disclose master geologic controls and delineate likely sites for geothermal and mineral resources. In many cases, geochemical and stable isotope data re- veal the origins of thermal fluids, and they can also provide estimates of reservoir temperatures and identify zones of fluid recharge.
