AIM To provide an updated assessment of the safety and efficacy of enhanced recovery after surgery(ERAS) protocols in elective gastric cancer(GC) *** Pub Med, Medline, EMBASE, World Health Organization International Trial Register, and Cochrane Library were searched up to June 2017 for all available randomized controlled trials(RCTs) comparing ERAS protocols and standard care(SC) in GC surgery. Thirteen RCTs, with a total of 1092 participants, were analyzed in this study, of whom 545 underwent ERAS protocols and 547 received SC *** No significant difference was observed between ERAS and control groups regarding total complications(P = 0.88), mortality(P = 0.50) and reoperation(P = 0.49). The incidence of pulmonary infection was significantly reduced(P = 0.03) following gastrectomy. However, the readmission rate after GC surgery nearly tripled under ERAS(P = 0.009). ERAS protocols significantly decreased the length of postoperative hospital stay(P < 0.00001) and medical costs(P < 0.00001), and accelerated bowel function recovery, as measured by earlier time to the first flatus(P = 0.0004) and the first defecation(P < 0.0001). Moreover, ERAS protocols were associated with a lower level of serum inflammatory response, higher serum albumin, and superior shortterm quality of life(QOL).CONCLUSION Collectively, ERAS results in accelerated convalescence, reduction of surgical stress and medical costs, improved nutritional status, and better QOL for GC patients. However, high-quality multicenter RCTs with large samples and long-term follow-up are needed to more precisely evaluate ERAS in radical gastrectomy.

An assessment of surrogate fuel using Bayesian multiple kernel learning model in sight of sooting tendency

引用

Frontiers in Energy 2022年第2期16卷 277-291页

作者： Lei zhu Zhan GAO Xiaogang CHENG fei ren Zhen HUANG Key Laboratory for Power Machinery and Engineering of the Ministry of Education Shanghai Jiao Tong UniversityShanghai 200030China

An integrated and systematic database of sooting tendency with more than 190 kinds of fuels was obtained through a series of experimental investigations. The laser-induced incandescence (LII) method was used to acquire the 2D distribution of soot volume fraction, and an apparatus-independent yield sooting index (YSI) was experimentally obtained. Based on the database, a novel predicting model of YSI values for surrogate fuels was proposed with the application of a machine learning method, named the Bayesian multiple kernel learning (BMKL) model. A high correlation coefficient (0.986) between measured YSIs and predicted values with the BMKL model was obtained, indicating that the BMKL model had a reliable and accurate predictive capacity for YSI values of surrogate fuels. The BMKL model provides an accurate and low-cost approach to assess surrogate performances of diesel, jet fuel, and biodiesel in terms of sooting tendency. Particularly, this model is one of the first attempts to predict the sooting tendencies of surrogate fuels that concurrently contain hydrocarbon and oxygenated components and shows a satisfying matching level. During surrogate formulation, the BMKL model can be used to shrink the surrogate candidate list in terms of sooting tendency and ensure the optimal surrogate has a satisfying matching level of soot behaviors. Due to the high accuracy and resolution of YSI prediction, the BMKL model is also capable of providing distinguishing information of sooting tendency for surrogate design.

Performance of FCC Catalyst Improved with Vanadium Trapping Components

引用

China Petroleum Processing & Petrochemical Technology 2014年第2期16卷 8-11页

作者： ren fei Liu Qianqian zhu Yuxia Research Institute of Petroleum Processing SINOPEC

The vanadium species were contaminated on FCC catalysts by using the Mitchell method. After the hydrothermal deactivation of the FCC catalysts, the cracking reaction was performed on these catalyst samples. The test results revealed that the conversion of feedstock and the gasoline yield obtained over the FCC catalysts with vanadium trapping components were obviously higher than those without addition of vanadium trapping components. The results also showed that the dry gas and coke selectivity on the FCC catalysts containing vanadium trapping components was improved. The X-Ray diffraction results proved that the zeolite crystal structure was well protected by the vanadium trapping components during its hydrothermal deactivation step. The results of SEM-EDX mapping disclosed that the vanadium was enriched on the vanadium trapping components which verified the positive function of vanadium trapping components.

Automatic character detection and segmentation in natural scene images

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第1期8卷 63-71页

作者： zhu Kai-hua QI fei-hu JIANG ren-jie XU Li Department of Computer Science and Technology Shanghai Jiao Tong University Shanghai 200030 China

We present a robust connected-component (CC) based method for automatic detection and segmentation of text in real-scene images. This technique can be applied in robot vision, sign recognition, meeting processing and video indexing. First, a Non-Linear Niblack method (NLNiblack) is proposed to decompose the image into candidate CCs. Then, all these CCs are fed into a cascade of classifiers trained by Adaboost algorithm. Each classifier in the cascade responds to one feature of the CC. Proposed here are 12 novel features which are insensitive to noise, scale, text orientation and text language. The classifier cascade allows non-text CCs of the image to be rapidly discarded while more computation is spent on promising text-like CCs. The CCs passing through the cascade are considered as text components and are used to form the segmentation result. A prototype system was built, with experimental results proving the effectiveness and efficiency of the proposed method.
