| 1 | Prediction of flyrock distance induced by mine blasting using a novel Harris Hawks optimization-based multi-layer perceptron neural network显示文摘In mining or construction projects,for exploitation of hard rock with high strength properties,blasting is frequently applied to breaking or moving them using high explosive energy.However,use of explosives may lead to the flyrock phenomenon.Flyrock can damage structures or nearby equipment in the surrounding areas and inflict harm to humans,especially workers in the working sites.Thus,prediction of flyrock is of high importance.In this investigation,examination and estimation/forecast of flyrock distance induced by blasting through the application of five artificial intelligent algorithms were carried out.One hundred and fifty-two blasting events in three open-pit granite mines in Johor,Malaysia,were monitored to collect field data.The collected data include blasting parameters and rock mass properties.Site-specific weathering index(WI),geological strength index(GSI) and rock quality designation(RQD)are rock mass properties.Multi-layer perceptron(MLP),random forest(RF),support vector machine(SVM),and hybrid models including Harris Hawks optimization-based MLP(known as HHO-MLP) and whale optimization algorithm-based MLP(known as WOA-MLP) were developed.The performance of various models was assessed through various performance indices,including a10-index,coefficient of determination(R^(2)),root mean squared error(RMSE),mean absolute percentage error(MAPE),variance accounted for(VAF),and root squared error(RSE).The a10-index values for MLP,RF,SVM,HHO-MLP and WOA-MLP are 0.953,0.933,0.937,0.991 and 0.972,respectively.R^(2) of HHO-MLP is 0.998,which achieved the best performance among all five machine learning(ML) models. | Bhatawdekar Ramesh Murlidhar Hoang Nguyen Jamal Rostami XuanNam Bui Danial Jahed Armaghani Prashanth Ragam Edy Tonnizam Mohamad | 2021 | Journal of Rock Mechanics and Geotechnical Engineering2021，13，6： | 6 |

| 4 | Estimation of the TBM advance rate under hard rock conditions using XGBoost and Bayesian optimization显示文摘The advance rate(AR)of a tunnel boring machine(TBM)under hard rock conditions is a key parameter in the successful implementation of tunneling engineering.In this study,we improved the accuracy of prediction models by employing a hybrid model of extreme gradient boosting(XGBoost)with Bayesian optimization(BO)to model the TBM AR.To develop the proposed models,1286 sets of data were collected from the Peng Selangor Raw Water Transfer tunnel project in Malaysia.The database consists of rock mass and intact rock features,including rock mass rating,rock quality designation,weathered zone,uniaxial compressive strength,and Brazilian tensile strength.Machine specifications,including revolution per minute and thrust force,were considered to predict the TBM AR.The accuracies of the predictive models were examined using the root mean squares error(RMSE)and the coefficient of determination(R^(2))between the observed and predicted yield by employing a five-fold cross-validation procedure.Results showed that the BO algorithm can capture better hyper-parameters for the XGBoost prediction model than can the default XGBoost model.The robustness and generalization of the BO-XGBoost model yielded prominent results with RMSE and R^(2) values of 0.0967 and 0.9806(for the testing phase),respectively.The results demonstrated the merits of the proposed BO-XGBoost model.In addition,variable importance through mutual information tests was applied to interpret the XGBoost model and demonstrated that machine parameters have the greatest impact as compared to rock mass and material properties. | Jian Zhou Yingui Qiu Shuangli Zhu Danial Jahed Armaghani Manoj Khandelwal Edy Tonnizam Mohamad | 2021 | Underground Space2021，6，5： | 4 |
| 5 | Effect of electrical stimulation of the lower esophageal sphincter in gastroesophageal reflux disease patients refractory to proton pump inhibitors显示文摘AIM: To evaluate the efficacy of lower esophageal sphincter(LES)-electrical stimulation therapy(EST) in a subgroup of patients that reported only partial response to proton pump inhibitors(PPIs) therapy, compared to a group of patient with complete response.METHODS: Bipolar stitch electrodes were laparoscopically placed in the LES and connected to an implantable pulse generator(EndoS tim BV, the Hague, the Netherlands), placed subcutaneously in the anterior abdominal wall. Stimulation at 20 Hz, 215 μsec, 3-8 m Amp in 30 min sessions was delivered starting on day 1 post-implant. Patients were evaluated using gastroesophageal reflux disease(GERD)-HRQL, symptom diaries; esophageal p H and esophageal manometry before and up to 24 mo after therapy and results were compared between partial and complete responders.RESULTS: Twenty-three patients with GERD on LESEST were enrolled and received continuous per-protocol stimulation through 12 mo and 21 patients completed 24 mo of therapy. Of the 23 patients, 16(8 male, mean age 52.1 ± 12 years) had incomplete response to PPIs prior to LES-EST, while 7 patients(5 male, mean age 52.7 ± 4.7) had complete response to PPIs. In the sub-group with incomplete response to PPIs, median(IQR) composite GERD-HRQL score improved significantly from 9.5(9.0-10.0) at baseline on-PPI and 24.0(20.8-26.3) at baseline off-PPI to 2.5(0.0-4.0) at 12-mo and 0.0(0.0-2.5) at 24-mo follow-up(P < 0.05 compared to on-and off-PPI at baseline). Median(IQR) % 24-h esophageal pH < 4.0 at baseline in this sub-group improved significantly from 9.8%(7.8-11.5) at baseline to 3.0%(1.9-6.3) at 12 mo(P < 0.001) and 4.6%(2.0-5.8) at 24 mo follow-up(P < 0.01). At their 24-mo follow-up, 9/11 patients in this sub-group were completely free of PPI use. These results were comparable to the sub-group that reported complete response to PPI therapy at baseline. No unanticipated implantation or stimulation-related adverse events, or any untoward sensation due to stimulation were reported in either group and LES-EST was safely tolerated by both groups. CONCLUSION: LES-EST is safe and effective in controlling symptoms and esophageal acid exposure in GERD patients with incomplete response to PPIs. These results were comparable to those observed PPI responders. | Edy Soffer Leonardo Rodríguez Patricia Rodriguez Beatriz Gómez Manoel G Neto Michael D Crowell | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，1： | 4 |
| 6 | ICC density predicts bacterial overgrowth in a rat model of post-infectious IBS显示文摘AIM:To investigate the interstitial cells of Cajal(ICC) number using a new rat model.METHODS:Sprague-Dawley rats were assigned to two groups.The first group received gavage with Campylobacter jejuni(C.jejuni) 81-176.The second group was gavaged with placebo.Three months after clearance of Campylobacter from the stool,precise segments of duodenum,jejunum,and ileum were ligated in self-contained loops of bowel that were preserved in anaerobic bags.Deep muscular plexus ICC(DMP-ICC) were quantified by two blinded readers assessing the tissue in a random,coded order.The number of ICC per villus was compared among controls,Campylobacter recovered rats without small intestinal bacterial overgrowth(SIBO),and Campylobacter recovered rats with SIBO.RESULTS:Three months after recovery,27% of rats gavaged with C.jejuni had SIBO.The rats with SIBO had a lower number of DMP-ICC than controls in the jejunum and ileum.Additionally there appeared to be a density threshold of 0.12 DMP-ICC/villus that was associated with SIBO.If ileal density of DMP-ICC was < 0.12 ICC/villus,54% of rats had SIBO compared to 9% among ileal sections with > 0.12(P<0.05).If the density of ICC was < 0.12 DMP-ICC/villus in more than one location of the bowel,88% of these had SIBO compared to 6% in those who did not(P<0.001).CONCLUSION:In this post-infectious rat model,the development of SIBO appears to be associated with a reduction in DMP-ICC.Further study of this rat model might help understand the pathophysiology of postinfectious irritable bowel syndrome. | Sam-Ryong Jee Walter Morales Kimberly Low Christopher Chang Amy Zhu Venkata Pokkunuri Soumya Chatterjee Edy Soffer Jeffrey L Conklin Mark Pimentel | 2010 | World Journal of Gastroenterology2010，16，29： | 3 |
| 7 | Effect of sucrose and potassium nitrate on biomass and saponin content of Talinum paniculatum Gaertn. hairy root in balloon-type bubble bioreactor显示文摘Objective:To increase biomass and saponin production in hairy root culture of Talinum paniculatum Gaertn.(T.paniculatum)in balloon-type bubble bioreactor(BTBB).Methods:Hairy roots which were collected from leaf explants of T.paniculatum were infected by Agrobacterium rhizogenes strain LB510.The hairy roots were cultivated at400 m L Murashige and Skoog liquid medium without growth regulator(MS0)in1 000 m L BTBB.Each BTBB had 2 g hairy roots as initial inoculum and these cultures were treated with various concentrations of sucrose(3%,4%,5%,6%w/v)and potassium nitrate(0.5,1.0,1.5 and 2.0 strength of MS medium).Cultures were maintained for 14days.Fresh and dry weights of hairy roots at the end of culture were investigated.Results:Various concentrations of sucrose influenced the biomass accumulation of hairy roots.Maximum biomass was reached by MS medium supplemented with 6%sucrose and it was approximately threefold higher than control.Culture supplemented with potassium nitrate at 2.0 strength of MS0 could increase biomass accumulation of hairy roots until 0.14 g dry weight and it was almost threefold higher than control.However,the maximum saponin content was obtained by MS medium supplemented with 5%sucrose and 2.0 strength potassium nitrate of MS.Conclusions:Based on this research,those conditions can be used to produce biomass and saponin of hairy root of T.paniculatum in the large scale. | Yosephine Sri Wulan Manuhara Alfinda Novi Kristanti Edy Setiti Wida Utami Arif Yachya | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，12： | 3 |
| 8 | Development and Characterization of Eco-Friendly Non-Isocyanate Urethane Monomer from Jatropha curcas Oil for Wood Composite Applications显示文摘The aim of this research work was to evaluate the potential of using renewable natural feedstock,i.e.,Jatropha curcas oil(JCO)for the synthesis of non-isocyanate polyurethane(NIPU)resin for wood composite applications.Commercial polyurethane(PU)is synthesized through a polycondensation reaction between isocyanate and poly-ol.However,utilizing toxic and unsustainable isocyanates for obtaining PU could contribute to negative impacts on the environment and human health.Therefore,the development of PU from eco-friendly and sustainable resources without the isocyanate route is required.In this work,tetra-n-butyl ammonium bromide was used as the activator to open the epoxy ring with 3-Aminopropyltriethoxisylane as a catalyst to yield urethane of JCO(UJCO).The UJCO were characterized by Fourier Transform Infra-Red spectroscopy(FTIR)and their oxirane,and hydroxyl values were measured.The result showed that a decrease in oxirane value was found while the hydroxyl value was increased during the time,confirming that the urethane group was formed.The presence of functional groups in FTIR spectra at wave numbers 1732.08,1562.34,and 3348.42 cm^(−1) indicates the functional groups of C=O(urethane carbonyl),–NH,and–OH,respectively confirmed this finding.The potential applications of NIPU in the wood composite were also outlined. | Samsul Bhakri Muhammad Ghozali Edy Cahyono Evi Triwulandari Witta Kartika Restu Nissa Nurfajrin Solihat Apri Heri Iswanto Petar Antov Viktor Savov Lee Seng Hua ErikaAyu Agustiany Lubos Kristak Widya Fatriasari | 2023 | Journal of Renewable Materials2023，11，1： | 2 |
| 9 | Comparison of catalyst-coated membranes and catalyst-coated substrate for PEMFC membrane electrode assembly:A review显示文摘Catalyst-coated membranes(CCMs)have gained popularity among membrane electrode assembly(MEA)fabricators for their abilities and advantages compared with those of other methods,such as catalyst-coated substrates(CCSs).CCMs show a profound new analysis for reducing platinum(Pt)catalyst loading.In addition,they increase the total number of reactions that occur on the MEA because of their active area amplification,which leads to an improved catalyst-utilization efficiency rate.Moreover,several characteristics are involved in the MEA fabrication methods.Material-manufacturing effects with regard to catalyst inks and analysis of the overall performance of MEAs prepared by the CCM and CCS methods are deliberated.This deliberation emphasizes the practical approaches in minimizing performance deterioration during the fabrication of MEAs using the CCM method and converses the commercialization of the CCM fabrication method toward developing an end product.Novel research is required for MEA fabrication using the CCM methods to ensure that the fuel cell performance is improved.Therefore,this review is focusing on the pros and cons of both distinguished methods,that is,CCM and CCS fabrication,for better comparison. | Bee Huah Lim Edy Herianto Majlan Ahmad Tajuddin Teuku Husaini Wan Ramli Wan Daud Nabilah Afiqah Mohd Radzuan Md.Ahsanul Haque | 2021 | Chinese Journal of Chemical Engineering2021，34，5： | 2 |
