| 1 | WJSC 6^(th) Anniversary Special Issues(2):Mesenchymal stem cells Mesenchymal stem cells in the treatment of spinal cord injuries:A review显示文摘With technological advances in basic research,the intricate mechanism of secondary delayed spinal cord injury(SCI)continues to unravel at a rapid pace.However,despite our deeper understanding of the molecular changes occurring after initial insult to the spinal cord,the cure for paralysis remains elusive.Current treatment of SCI is limited to early administration of high dose steroids to mitigate the harmful effect of cord edema that occurs after SCI and to reduce the cascade of secondary delayed SCI.R ecent evident-based clinical studies have cast doubt on the clinical benefit of steroids in SCI and intense focus on stem cell-based therapy has yielded some encouraging results.An array of mesenchymal stem cells(MSCs)from various sources with novel and promising strategies are being developed to improve function after SCI.In this review,we briefly discuss the pathophysiology of spinal cord injuries and characteristics and the potential sources of MSCs that can be used in the treatment of SCI.We will discuss the progress of MSCs application in research,focusing on the neuroprotective properties of MSCs.Finally,we will discuss the results from preclinical and clinical trials involving stem cell-based therapy in SCI. | Venkata Ramesh Dasari Krishna Kumar Veeravalli Dzung H Dinh | 2014 | World Journal of Stem Cells2014，6，2： | 32 |

| 3 | Diurnal characteristics of geoelectric fields and their changes associated with the Alxa Zuoqi M_S5.8 earthquake on 15 April 2015(Inner Mongolia)显示文摘In China, efforts are being made to monitor geoelectric fields through a large network of stations deployed and managed by the China Earthquake Administration. The diurnal variations in the geoelectric field waveforms were similar in the quiet magnetic periods when K<5(generally, K<3 indicates a quiet time). The arrival time points of the maxima in the geoelectric field waveforms exhibited differences in local time related to geographic longitude. The amplitude of diurnal variation was several to 16.6 mV/km and decreased with increasing latitude. Further,the amplitude of diurnal variation, which was related to seasonal changes, was larger in summer and autumn than in spring and winter. The periods of diurnal changes during quiet days were 24, 12, 8, 6, 4 hours and several minutes over large areas. Finally, the observed diurnal variations in geoelectric field prior to the Alxa Zuoqi M_S5.8 earthquake on 15 April 2015 were studied, and pronounced changes in the spectral values of the geoelectric fields were found to be associated with the Alxa Zuoqi earthquake in Inner Mongolia. | Qing Ye Ye Fan Xuebin Du Tengfa Cui Kechang Zhou Ramesh P.Singh | 2018 | Earthquake Science2018，31，1： | 12 |
| 4 | Understanding the multifunctionality in Cu-doped BiVO_4 semiconductor photocatalyst显示文摘A visible light-induced, Cu-doped BiVO_4 photocatalyst was synthesized by a microwave hydrothermal method. The photocatalytic efficiency was investigated in the degradation of model water pollutants like Methylene Blue(dye) and ibuprofen(pharmaceuticals), as well as the inactivation of Escherichia coli(bacteria). The Cu-doped BiVO4 samples showed better efficiency than undoped BiVO_4, and the 1 wt.% Cu-doped BiVO_4 sample showed the best efficiency. The degradation of Methylene Blue reached 95%, while the degradation of ibuprofen reached 75%, and the inactivation of E. coli reached 85% in irradiation with visible light. The appearance of additional absorption band shoulders and widening of the optical absorption in the visible range makes the prepared powder an efficient visible light-driven photocatalyst. Moreover, the formation of an in-gap energy state just above the valance band as determined by density functional theory(DFT) first principle calculation, facilitates the wider optical absorption range of the doped system. Similarly, this in-gap energy state also acts as an electron trap, which is favorable for the efficient separation and photoexcited charge carriers' transfer process. The formation of oxygen vacancies due to doping also improved the separation of the charge carrier, which promoted the trapping of electrons and inhibited electron hole recombination, thus increasing the photocatalytic activity. No decrease in the efficiency of the 1 wt.% Cu-doped BiVO_4 photocatalyst in the degradation of ibuprofen over three consecutive cycles revealed the stability of the photocatalyst towards photocorrosion. These findings highlight the multifunctional applications of Cu-doped BiVO_4 in wastewater containing multiple pollutants. | Chhabilal Regmi Yuwaraj K.Kshetri Ramesh Prasad PANDey Tae-Ho Kim Gobinda Gyawali Soo Wohn Lee | 2019 | Journal of Environmental Sciences2019，31，1： | 12 |
| 5 | Predictive value of multi-detector computed tomography for accurate diagnosis of serous cystadenoma:Radiologic-pathologic correlation显示文摘AIM:To identify multi-detector computed tomography(MDCT) features most predictive of serous cystadenomas(SCAs),correlating with histopathology,and to study the impact of cyst size and MDCT technique on reader performance.METHODS:The MDCT scans of 164 patients with surgically verified pancreatic cystic lesions were reviewed by two readers to study the predictive value of various morphological features for establishing a diagnosis of SCAs.Accuracy in lesion characterization and reader conf idence were correlated with lesion size(≤3cm or≥3cm) and scanning protocols(dedicated vs routine).RESULTS:28/164 cysts(mean size,39 mm;range,8-92mm) were diagnosed as SCA on pathology.The MDCT features predictive of diagnosis of SCA were microcystic appearance(22/28,78.6%),surface lobulations(25/28,89.3%) and central scar(9/28,32.4%).Stepwise logistic regression analysis showed that only microcystic appearance was signifi cant for CT diagnosis of SCA(P=0.0001).The sensitivity,specificity and PPV of central scar and of combined microcystic appearance and lobulations were 32.4%/100%/100% and 68%/100%/100%,respectively.The reader confidence was higher for lesions>3cm(P=0.02) and for MDCT scans performed using thin collimation(1.25-2.5mm) compared to routine 5 mm collimation exams(P>0.05).CONCLUSION:Central scar on MDCT is diagnostic of SCA but is seen in only one third of SCAs.Microcystic morphology is the most significant CT feature in diagnosis of SCA.A combination of microcystic appearance and surface lobulations offers accuracy comparable to central scar with higher sensitivity. | Anjuli A Shah Nisha I Sainani Avinash Kambadakone Ramesh Zarine K Shah Vikram Deshpande Peter F Hahn Dushyant V Sahani | 2009 | World Journal of Gastroenterology2009，15，22： | 11 |

| 8 | Antioxidant and antimutagenic activities of bark extract of Terminalia arjuna显示文摘Objective:The alcoholic extract of stem bark of Terminalia arjuna(ALTA) was screened for antioxidant and antimutagenic(anticlastogenic) activity.Methods:Antioxidant property was determined by l,l,Diphynyl,2-Picryl hydrazyl(DPPH) assay,super oxide radical scavenging activity,lipid peroxidation assay and total polyphenolic content was determined by Folin-Ciocalteau’s reagent.Antimutagenic activity was evaluated using micronucleus test in mice. Results:The ALTA has shown potent antioxidant activity with EC50 of 2.491±0.160,50.110±0.150 & 71.000±0.250 in DPPH assay,superoxide radical scavenging activity and lipid peroxidation assay, which is comparable with ascorbic acid with EC50 of 2.471±0.140,40.500±0.390 and 63.000±0.360 respectively.In micronucleus test,ALTA(100 & 200 mg/kg,p.o.) showed significant reduction in percentage of micronucleus in both polychromatic erythrocytes(PCE) and normochromatie erythrocytes(NCE) and also shown significant reduction in P/N ratio.Conclusions:These results suggested that ALTA possess significant antioxidant and antimutagenic activity. | Gollapalle Lakshminarayana shastry Viswanatha Santosh Kumar Vaidya Ramesh C Nandakumar Krishnadas Srinath Rangappa | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，12： | 9 |
| 9 | Intravenous vitamin C as adjunctive therapy for enterovirus/rhinovirus induced acute respiratory distress syndrome显示文摘We report a case of virus-induced acute respiratory distress syndrome(ARDS) treated with parenteral vitamin C in a patient testing positive for enterovirus/rhinovirus on viral screening. This report outlines the first use of high dose intravenous vitamin C as an interventional therapy for ARDS, resulting from enterovirus/rhinovirus respiratory infection. From very significant preclinical research performed at Virginia Commonwealth Universitywith vitamin C and with the very positive results of a previously performed phase Ⅰ safety trial infusing high dose vitamin C intravenously into patients with severe sepsis, we reasoned that infusing identical dosing to a patient with ARDS from viral infection would be therapeutic. We report here the case of a 20-year-old, previously healthy, female who contracted respiratory enterovirus/rhinovirus infection that led to acute lung injury and rapidly to ARDS. She contracted the infection in central Italy while on an 8-d spring break from college. During a return flight to the United States, she developed increasing dyspnea and hypoxemia that rapidly developed into acute lung injury that led to ARDS. When support with mechanical ventilation failed, extracorporeal membrane oxygenation(ECMO) was initiated. Twelve hours following ECMO initiation, high dose intravenous vitamin C was begun. The patient's recovery was rapid. ECMO and mechanical ventilation were discontinued by day-7 and the patient recovered with no long-term ARDS sequelae. Infusing high dose intravenous vitamin C into this patient with virus-induced ARDS was associated with rapid resolution of lung injury with no evidence of post-ARDS fibroproliferative sequelae. Intravenous vitamin C as a treatment for ARDS may open a new era of therapy for ARDS from many causes. | Alpha A Fowler Ⅲ Christin Kim Lawrence Lepler Rajiv Malhotra Orlando Debesa Ramesh Natarajan Bernard J Fisher Aamer Syed Christine DeWilde Anna Priday Vigneshwar Kasirajan | 2017 | World Journal of Critical Care Medicine2017，6，1： | 9 |
| 10 | Metabolic syndrome and chronic kidney disease:Current status and future directions显示文摘Metabolic syndrome(Met S) is a term used to denote a combination of selected,widely prevalent cardiovascular disease(CVD)-related risk factors.Despite the ambiguous definition of Met S,it has been clearly associated with chronic kidney disease markers including reduced glomerular filtration rate,proteinuria and/or microalbuminuria,and histopathological markers such as tubular atrophy and interstitial fibrosis.However,the etiological role of Met S in chronic kidney disease(CKD) is less clear.The relationship between MetS and CKD is complex and bidirectional,and so is best understood when CKD is viewed as a common progressive illness along the course of which MetS,another common disease,may intervene and contribute.Possible mechanisms of renal injury include insulin resistance and oxidative stress,increased proinflammatory cytokine production,increased connective tissue growth and profibrotic factor production,increased microvascular injury,and renal ischemia.MetS also portends a higher CVD risk at all stages of CKD from early renal insufficiency to end-stage renal disease.Clinical interventions for MetS in the presence of CKD should include a combination of weight reduction,appropriate dietary modification and increase physical activity,plus targeting of individual CVD-related risk factors such as dysglycemia,hypertension,and dyslipidemia while conforming to relevant national societal guidelines. | G V Ramesh Prasad | 2014 | World Journal of Nephrology2014，3，4： | 8 |
| 11 | New-onset diabetes mellitus after kidney transplantation:Current status and future directions显示文摘A diagnosis of new-onset diabetes after transplantation(NODAT) carries with it a threat to the renal allograft,as well as the same short-and long-term implications of type 2 diabetes seen in the general population.NODAT usually occurs early after transplantation,and is usually diagnosed according to general population guidelines.Non-modifiable risk factors for NODAT include advancing age,African American,Hispanic,or South Asian ethnicity,genetic background,a positive family history for diabetes mellitus,polycystic kidney disease,and previously diagnosed glucose intolerance.Modifiable risk factors for NODAT include obesity and the metabolic syndrome,hepatitis C virus and cytomegalovirus infection,corticosteroids,calcineurin inhibitor drugs(especially tacrolimus),and sirolimus.NODAT affects graft and patient survival,and increases the incidence of post-transplant cardiovascular disease.The incidence and impact of NODAT can be minimized through pre-and post-transplant screening to identify patients at higher risk,including by oral glucose tolerance tests,as well as multi-disciplinary care,lifestyle modification,and the use of modified immunosuppressive regimens coupled with glucose-lowering therapies including oral hypoglycemic agents and insulin.Since NODAT is a major cause of post-transplant morbidity and mortality,measures to reduce its incidence and impact have the potential to greatly improve overall transplant success. | Sneha Palepu G V Ramesh Prasad | 2015 | World Journal of Diabetes2015，6，3： | 8 |
| 12 | Contrast induced neurotoxicity following coronary angiogram with Iohexol in an end stage renal disease patient显示文摘Neurotoxicity is an infrequent adverse reaction to iodinated contrast agents. Contrast induced neurotoxicity following coronary angiogram is very rare. Renal disease is a risk factor for contrast induced neurotoxicity. We report a case of contrast induced neurotoxicity following coronary angiogram and intervention using Iohexol(Omnipaque 350) in an end stage renal disease patient on peritoneal dialysis who had prior exposure to iodinated contrast without any adverse reaction. Hemodialysis had to be initiated for rapid removal of the contrast agent with subsequent complete resolution of neurological deficits. This case highlights the need for interventionalists to be aware of an important adverse reaction to iodinated contrast agents, especially in individuals with renal dysfunction, and that neurotoxicity is a possibility even with prior uneventful exposures. The role and timing of hemodialysis in contrast induced neurotoxicity in patients with chronic kidney disease and in those without chronic kidney disease needs further deliberation. | Narasimha Swamy Gollol Raju Deepak Joshi Ramesh Daggubati Assad Movahed | 2015 | World Journal of Clinical Cases2015，3，11： | 8 |
| 13 | Colorectal cancers in ulcerative colitis from a low-prevalence area for colon cancer显示文摘AIM: To determine the incidence and risk factors for colorectal cancer(CRC) in patients with ulcerative colitis from a low prevalence region for CRC.METHODS: Our prospective database yielded a cohort of 430 patients [age: 44 ± 14.6 years; 248 men(57.7%)] with ulcerative colitis(median disease duration 6, range: 1-39 years) for analysis. Of these, 131(30.5%) had left-sided colitis and 159(37%) extensive colitis. Patients with histologically confirmed CRC within the segment with colitis were compared with those without CRC, to determine the risk factors for the development of CRC.RESULTS: Twelve patients(2.8%) developed CRC. The overall incidence density was 3.56/1000 patient-years of disease- 3/1000 in the first 10 years, 3.3/1000 at 10 to 20 years, and 7/1000 at > 20 years. Three of our 12 patients developed CRC within 8 years of disease onset. On univariate analysis, extensive colitis, longer duration of disease, and poor control of disease were associated with development of CRC. On multivariate analysis, duration of disease and extent of colitis remained significant.CONCLUSION: CRC occurred in 2.8% of patients with ulcerative colitis in our population- an incidence density similar to that in Western countries in spite of a low overall prevalence of colon cancer in our population.The risk increased with extent and duration of disease. | Devendra Desai Sudeep Shah Abhijit Deshmukh Philip Abraham Anand Joshi Tarun Gupta Ramesh Deshpande Varun Khandagale Siji George | 2015 | World Journal of Gastroenterology2015，21，12： | 7 |
| 14 | NG2 Cell Response in the CNP-EGFP Mouse After Contusive Spinal Cord Injury显示文摘成年动物中枢神经系统中的NG2细胞具有异质性。脊髓损伤(SCI)后,具有少突胶质前体细胞(OPCs)功能的NG2细胞亚型如何产生反应性变化及对其正常的发育过程有何影响目前还不清楚。本文采用少突胶质细胞系细胞表达EGFP的CNP-EGFP小鼠,研究正常和SCI后的NG2细胞的特征。在正常小鼠的白质中,对EGFP+NG2+双极细胞和EGFPnegNG2+多极细胞进行鉴别。SCI后,白质损伤边缘区中的EGFP+NG2+细胞3 d增殖达高峰,损伤中心区的EGFPnegNG2+细胞增殖在损伤后7 d达高峰。损伤后EGFP+NG2+细胞的Olig2、Sox10、Sox17等转录因子、基本的膜电生理参数以及钾电流表型均与发育过程增殖的OPCs一致。EGFPnegNG2+细胞不表达少突胶质发生中的转录因子。EGFP+CC1+少突胶质细胞6周时包含在EGFP+NG2+细胞增殖峰时表达BrdU的细胞。EGFPnegCC1+少突胶质细胞未被观察到。神经胶质生长因子2和成纤维细胞生长因子2处理促进少突胶质发生,提高EGFPnegNG2+细胞数量。因此,通过EGFP和转录因子表达,时空增殖类型及对生长因子的反应,两种类型的NG2+细胞对SCI刺激发生反应。SCI后EGFP+NG2+细胞经受细胞和生理变化特征,与在早期出生后的少突胶质发生过程中NG2+细胞中的变化类似。 | JUDITH M LYTLE RAMESH CHITTAJALLU JEAN R WRATHALL VITTORIO GALLO | 2009 | 神经损伤与功能重建2009，4，1： | 7 |
| 15 | Retinal structural-vascular-functional relationship using optical coherence tomography and optical coherence tomography -angiography in myopia显示文摘Background:To examine the retinal structure–vascular-function relationship using optical coherence tomography(OCT)and optical coherence tomography angiography(OCTA)in myopia.Methods:This was a prospective cross-sectional study comprising 86 eyes of 45 individuals with varying axial lengths and spherical equivalents and no posterior segment abnormalities.All eyes underwent optical coherence tomography with the Spectralis SD-OCT and OCTA with RTVue-XR Avanti;Optovue.Individual macular retinal layer thicknesses and flow areas and vessel densities were measured on OCT and OCTA,respectively.Linear correlations were made between the macular layer thicknesses,flow areas and vessel densities with axial length,spherical equivalent and visual acuity.Results:The participants’mean ages were 33.34±14.45 years,mean spherical equivalent refractions were−7.17±5.71 D and axial lengths were 25.95±2.41 mm.There were significant positive correlations of foveal angle(r=0.757,p=0.001),inner retinal(r=0.764,p=0.001)and outer plexiform layer(r=0.771,p=0.001)thickness on OCT and vessel densities in deep capillary plexus(r=0.313,p=0.003)on OCTA with axial length and negative correlations with spherical equivalents and visual acuity.Significant negative correlations of outer nuclear layer(r=−0.560,p=0.03)and photoreceptor outer segment layer thickness(r=−0.856,p<0.001)were noted on OCT with axial length and positive correlations with spherical equivalents and visual acuity.Conclusion:The lateral retinal stretching in myopia could possibly explain the correlation between retinal layer thickness,vascular density and visual acuity in these eyes.Further research is required to investigate this. | Ramesh Venkatesh Shivani Sinha Deepika Gangadharaiah Santosh G.K.Gadde Ashwin Mohan Rohit Shetty Naresh Kumar Yadav | 2019 | Eye and Vision2019，6，1： | 7 |
| 16 | Plasticized Polymer Electrolyte Membranes Based on PEO/PVdF-HFP for Use as an Effective Electrolyte in Lithium-ion Batteries显示文摘Plasticized polymer electrolytes were prepared using poly(ethylene oxide)(PEO)/poly(vinylidene fluoridehexafluoro propylene)(PVd F-HFP) with lithium perchlorate(Li Cl O4) and different plasticizers. XRD and FTIR spectroscopic techniques were used to characterize the structure and the complexation of plasticizer with the host polymer matrix. The role of interaction between polymer hosts and plasticizer on conductivity is discussed using the results of alternating current(a.c.) impedance studies. TG-DTA and SEM were used for thermal and physical characterizations. Maximum ionic conductivity(3.26 × 10^(-4) S·cm^(-1)) has been observed for ethylene carbonate(EC)-based polymer electrolytes. Electrochemical performance of the plasticized polymer electrolyte is evaluated in LiFePO_4/plasticized polymer electrolytes(PPEs)/Li coin cell. Good performance with low capacity fading on charge discharge cycling is demonstrated. | pradeepa prabakaran ramesh prabhu manimuthu sowmya gurusamy edwinraj sebasthiyan | 2017 | Chinese Journal of Polymer Science2017，35，3： | 7 |
| 17 | Genetically modified mouse models for the study of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is associated with obesity,insulin resistance,and type 2 diabetes.NAFLD represents a large spectrum of diseases ranging from(1) fatty liver(hepatic steatosis);(2) steatosis with inflammation and necrosis;to(3) cirrhosis.The animal models to study NAFLD/nonalcoholic steatohepatitis(NASH) are extremely useful,as there are still many events to be elucidated in the pathology of NASH.The study of the established animal models has provided many clues in the pathogenesis of steatosis and steatohepatitis,but these remain incompletely understood.The different mouse models can be classified in two large groups.The first one includes genetically modified(transgenic or knockout) mice that spontaneously develop liver disease,and the second one includes mice that acquire the disease after dietary or pharmacological manipulation.Although the molecular mechanism leading to the development of hepatic steatosis in the pathogenesis of NAFLD is complex,genetically modified animal models may be a key for the treatment of NAFLD.Ideal animal models for NASH should closely resemble the pathological characteristics observed in humans.To date,no single animal model has encompassed the full spectrum of human disease progression,but they can imitate particular characteristics of human disease.Therefore,it is important that the researchers choose the appropriate animal model.This review discusses various genetically modified animal models developed and used in research on NAFLD. | Perumal Nagarajan M Jerald Mahesh Kuma Ramasamy Venkatesan Subeer S Majundar Ramesh C Juyal M Jerald Mahesh Kuma | 2012 | World Journal of Gastroenterology2012，18，11： | 7 |
| 18 | Post-transplant dyslipidemia: Mechanisms, diagnosis and management显示文摘Post-transplant dyslipidemia is highly prevalent and presents unique management challenges to the clinician. The two major outcomes to considerwith post-transplant therapies for dyslipidemia are preserving or improving allograft function, and reducing cardiovascular risk. Although there are other cardiovascular risk factors such as graft dysfunction, hypertension, and diabetes, attention to dyslipidemia is warranted because interventions for dyslipidemia have an impact on reducing cardiac events in clinical trials specific to the transplant population. Dyslipidemia is not synonymous with hyperlipidemia. Numerous mechanisms exist for the occurrence of posttransplant dyslipidemia, including those mediated by immunosuppressive drug therapy. Statin therapy has received the most attention in all solid organ transplant recipient populations, although the effect of proper dietary advice and adjuvant pharmacological and nonpharmacological agents should not be dismissed. At all stages of treatment appropriate monitoring strategies for side effects should be implemented so that the benefits from these therapies can be achieved. Clinicians have a choice when there is a conflict between various transplant society and lipid society guidelines for therapy and targets. | Arnav Agarwal G V Ramesh Prasad | 2016 | World Journal of Transplantation2016，6，1： | 6 |
| 19 | Role of tissue microenvironment resident adipocytes in colon cancer显示文摘Colorectal cancer(CRC) is a multifactorial disease characterized by several genetic and epigenetic alterations occurring in epithelial cells. It is increasingly recognized that tumour progression is also regulated by tumour microenvironment(TME). The bidirectional cross-talk between tumour resident adipocytes and cancer cells within TME has been proposed as active contributor to carcinogenesis. Tumour resident adipocytes exhibit an activated phenotype characterized by increased secretion of pro-tumorigenic factors(angiogenic/inflammatory/immune) which contribute to cancer cell proliferation, invasion, neoangiogenesis, evasion of immune surveillance and therapy resistance. Furthermore, adipocytes represent a fuel rich source for increasing energy demand of rapidly proliferating tumour cells. Interestingly, a relationship between obesity and molecular variants in CRC has recently been identified. Whether adipose tissue promotes cancer progression in subsets of molecular phenotypes or whether local tissue adipocytes are involved in inactivation of tumour suppressor genes and/or activation of oncogenes still needs to be explored. This editorial highlights the major findings related to crosstalk between adipocytes and colon cancer cells and how local paracrine interactions may promote cancer progression. Furthermore, we provide future strategies in studying colonic TME which could provide insights in bidirectional cross-talk mechanisms between adipocytes and colonic epithelial cells. This could enable to decipher critical signalling pathways of both early colonic carcinogenesis and cancer progression. | Maria Tabuso Shervanthi Homer-Vanniasinkam Raghu Adya Ramesh P Arasaradnam | 2017 | World Journal of Gastroenterology2017，23，32： | 6 |
| 20 | 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 |
