Geochemical characteristics of different Gosau depositional systems, basins and sediment provenance using major-, trace-, and rare earth elements were also investigated. Geochemical proxies such as boron concentrations were tested for seeking the possibilities of paleosalinity indicators. Due to the [act that several pelagic sections are represented by extremely low boron contents, B/AI＊ ratios are recognized as more robust and differentiate reliably between marine （mean： 160 ± 34） and non-marine （mean： 133 ± 33） samples. Using statistical factor analysis, hemipelagic to pelagic samples flom the Gieghi_ibl Syncline and Slovakian equivalents can be differentiated from marginal-marine to non-marine samples from the Grtinbach and Glinzendorf Syncline related to terrigenous （SiO2, AI203, K20, Th, Rb, Zr and others） and pelagic indicative elements （CaO, St, TOT/C and B/AI＊）. A clear indication for ophiolitic provenance is traced by high amounts of chromium and nickel. Only non-marine successions of the Glinzendorf Syncline show higher Cr and Ni concentrations （up to 250 and 400 ppm, respectively） and enriched Cr/V and Y/Ni ratios trending to an ultramafic source.展开更多

In this study, we investigate if there is a systematic difference coming from the choice between the Vienna Mapping Function 1(VMF1) and the Global Mapping Function(GMF) for the modeling of Zenith Total Delay(ZTD) estimates, as well as the Integrated Precipitable Water Vapor(IPWV) estimates that are deduced from them. As ZTD estimates cannot be fully separated from coordinate estimates, we also investigated the coordinate repeatability between subsequent measurements.For this purpose, we monitored twelve GNSS stations on a global scale, for each of the three climatic zones(polar, mid-latitudes and tropical), with four stations on each zone. We used an automated processing based on the Bernese GNSS Software Version 5.2 by applying the Precise Point Positioning(PPP)approach, L3 Ionosphere-free linear combination, 7 cutoff elevation angle and 2 h sampling. We noticed an excellent agreement with the ZTD estimates and coordinate repeatability for all the stations w.r.t to CODE(the Center for Orbit Determination in Europe) and USNO(US Naval Observatory) products, except for the Antarctic station(Davis) which shows systematic biases for the GMF related results. As a final step, we investigated the effect of using two mapping functions(VMF1 and GMF) to estimate the IPWV,w.r.t the IPWV estimates provided by the Integrated Global Radiosonde Archive(IGRA). The GPS-derived IPWV estimates are very close to the radiosonde-derived IPWV estimates, except for one station in the tropics(Tahiti).展开更多

We investigated the relationship between diagnoses based on cold biopsy samples using the revised Vienna Classification and resected specimens of the same lesions, and the therapeutic implications of diagnoses made using the revised Vienna Classification. The same cold biopsy specimens were also examined using the Japanese Group Classification guidelines, and compared with the resected specimens of the same lesions for reference.RESULTS： A total of 179 lesions were identified. The sensitivity, specificity, positive and negativepredictive values of the revised Vienna Classification for distinguishing between intramucosal lesions and submucosal invasive carcinomas in cold biopsy specimens was 22.2%, 100%, 100%, and 71.4%,respectively, and for distinguishing between intramucosal lesions and those invading the submucosa or beyond was 59.7%, 100%, 100%, and 37.6%,respectively. The sensitivity, specificity, positive and negative predictive values of the Japanese Group Classification for distinguishing between intramucosal lesions and submucosal invasive carcinomas in cold biopsy specimens was 83.3%, 91.4%, 83.3%. and 91.4%, respectively, and for distinguishing between intramucosal lesions and those invading the submucosa or beyond was 95.1%, 91.4%, 97.9%, and 82.1%, respectively. A total of 137 of 144 carcinomas that had invaded the submucosa or beyond and three high-grade intraepithelial neoplasias were diagnosed as ＂carcinoma＂ using the Japanese Group Classificat展开更多

The mainstream new energy charging module consists of a front-end AC/DC converter and a back-end DC/DC converter. This article focuses on the stability control of the three-phase three-level Vienna PFC circuit in the front-end AC/DC section, establishes a mathematical model, and derives the transfer function from control to output. A dual closed-loop control strategy based on three-level Vienna PFC circuit was studied, and two tuning methods for control parameters were studied. Firstly, a current inner loop control model was constructed based on feed forward decoupling method, and a voltage outer loop control model was designed based on power balance;The second is that the current inner loop adopts a Type I system and the voltage outer loop adopts a Type II system to design control parameters. A simulation comparison was conducted on the tuning results of two control parameters, and a better voltage and current loop control parameter tuning method was obtained. The correctness of the method was verified through simulation and experiments.展开更多
