17Intelligent Machine Learning Enabled Retinal Blood Vessel Segmentation and Classification显示文摘Automated segmentation of blood vessels in retinal fundus images is essential for medical image analysis.The segmentation of retinal vessels is assumed to be essential to the progress of the decision support system for initial analysis and treatment of retinal disease.This article develops a new Grasshopper Optimization with Fuzzy Edge Detection based Retinal Blood Vessel Segmentation and Classification(GOFED-RBVSC)model.The proposed GOFED-RBVSC model initially employs contrast enhancement process.Besides,GOAFED approach is employed to detect the edges in the retinal fundus images in which the use of GOA adjusts the membership functions.The ORB(Oriented FAST and Rotated BRIEF)feature extractor is exploited to generate feature vectors.Finally,Improved Conditional Variational Auto Encoder(ICAVE)is utilized for retinal image classification,shows the novelty of the work.The performance validation of the GOFEDRBVSC model is tested using benchmark dataset,and the comparative study highlighted the betterment of the GOFED-RBVSC model over the recent approaches.Nora Abdullah Alkhaldi Hanan T.Halawani 2023Computers, Materials & Continua2023,,1:0
18Accelerating the elimination of hepatitis C in Kuwait: An expert opinion显示文摘The hepatitis C virus(HCV)is estimated to affect 71 million people worldwide.In 2016,the World Health Organization adopted the first global health sector strategy to eliminate viral hepatitis as a public health threat by 2030.In December 2018,the European Association for the Study of the Liver,International Liver Foundation convened an expert panel to address the elimination of HCV in Kuwait.Several steps have already been taken to eliminate HCV in Kuwait,including free HCV treatment for Kuwait’s citizens,high blood safety standards,and the implementation of screening and awareness programs.The expert panel made several recommendations aimed at accelerating the elimination of HCV in Kuwait:The development of a national strategy and action plan to guide all HCV elimination activities;the formation of a coordination mechanism to support collaboration between hepatitis working committees;the prioritization of microelimination at primary,secondary or tertiary facilities,in prisons and rehabilitation centers;and ensuring the involvement of multiple stakeholders–including relevant civil society groups–in all activities.Enhanced screening and linkage to care should be prioritized in Kuwait,with the expansion of the prescriber base to primary healthcare providers and nurse practitioners to be considered.Raising awareness and educating people about HCV infection also remain essential to achieve the goal of HCV elimination.Lastly,a national HCV registry should be developed to help monitor the implementation of viral hepatitis plans and progress towards achieving national and international targets.Fuad Hasan Ahmad Alfadhli Abeer Al-Gharabally Mahmoud Alkhaldi Massimo Colombo Jeffrey V Lazarus 2020World Journal of Gastroenterology2020,26,30:0
19New insights into hydraulic fracturing fluids used for hightemperature wells显示文摘Current interest in deep,low-permeability formations(<10 md)demands accelerated development of high-temperature hydraulic fracturing technologies.Conventional guar systems break down above 300°F and require higher polymer loadings to maintain thermal stability.However,higher polymer loadings generate more residue and damage to the proppant pack and the formation.To resolve these problems,a variety of high-temperature stabilizers are added to enhance the thermal stability of these fracturing fluids at temperatures above 300F.The focus of this work is to:(1)identify those additives that best enhance temperature stability of fracturing fluids and(2)study the rheological influence of incorporating these additives on the fracturing fluid systems.The experimental fracturing-fluid solutions were prepared at a total polymer concentration of 30 and 40 lb/1000 gal.Additives such as synthetic polymer,oxygen scavengers,crosslinkers,crosslinker delay additives,and pH buffers were examined in this work.Hydrated polymer solutions were crosslinked with a metallic crosslinker between 200 and 400°F.Viscosity measurements were carried out in a highpressure/high-temperature(HP/HT)rheometer to evaluate rheology and thermal stability.Results show that adding a synthetic polymer and a crosslinker with the slowest reaction rate improves the fracturing fluid thermal stability.Of the three other additives tested,oxygen scavengers showed the greatest enhancement to thermal stability while pH buffers showed the least.Through the addition of high-temperature stabilizing additives,the fracturing fluid in this work was able to maintain a stable performance at temperatures up to 400°F.Maintaining the thermal stability of fracturing fluids at a lower polymer loading remains a challenge in the industry.This work proposes techniques that can be used to enhance the thermal stability of fracturing fluids.Deeper knowledge about these different techniques will allow for better additive development and application in the field.Tariq Almubarak Leiming Li Jun Hong Ng Hisham Nasr-El-Din Mohammed AlKhaldi 2021Petroleum2021,7,1:0
