1Laser cleaning of steel structure surface for paint removal and repaint adhesion显示文摘Paint removal from steel structure is executed for shipyards of marine and offshore engineering.Due to environmental unfriendliness and unhealthy drawbacks of sand blasting technique, laser ablation technique is proposed as a substituting method.By absorbing high energy of the 1064 nm pulsed laser, the paint is vaporized quickly.The ablated debris is then collected by using a suction pump.Initial metal surface of the steel is exposed when laser beam irradiates perpendicularly and scans over it.The cleaned surface fulfills the requirements of surface preparation standards ISO 8501 of SA2.The adhesion is further characterized with pull-off test after carrying out painting with Jotamastic 87 aluminum paint.The repainting can be embedded onto the laser cleaned surface to bond much more tightly.The excellent adhesion strength of 20 MPa between repainted coating and the substrate is achieved, which is higher than what is required by shipyards applications.Xiaoguang Li Tingting Huang Ang Wei Chong Rui Zhou Yoo Sang Choo Minghui Hong 2017光电工程2017,44,3:24

5Systematic review of the outcomes of surgical resection for intermediate and advanced Barcelona Clinic Liver Cancer stage hepatocellular carcinoma:A critical appraisal of the evidence显示文摘AIM To perform a systematic review to determine the survival outcomes after curative resection of intermediate and advanced hepatocellular carcinomas(HCC).METHODS A systematic review of the published literature was performed using the PubM ed database from 1 st January 1999 to 31 st Dec 2014 to identify studies that reported outcomes of liver resection as the primary curative treatment for Barcelona Clinic Liver Cancer(BCLC) stage B or C HCC. The primary end point was to determine the overall survival(OS) and disease free survival(DFS) of liver resection of HCC in BCLC stage B or C in patients with adequate liver reserve(i.e., Child's A or B status). The secondary end points were to assess the morbidity and mortality of liver resection in large HCC(defined as lesions larger than 10 cm in diameter) and to compare the OS and DFS after surgical resection of solitary vs multifocal HCC.RESULTS We identified 74 articles which met the inclusion criteria and were analyzed in this systematic review. Analysis of the resection outcomes of the included studies were grouped according to(1) BCLC stage B or C HCC,(2) Size of HCC and(3) multifocal tumors. The median 5-year OS of BCLC stage B was 38.7%(range 10.0-57.0); while the median 5-year OS of BCLC stage C was 20.0%(range 0.0-42.0). The collective median 5-year OS of both stages was 27.9%(0.0-57.0). In examining the morbidity and mortality following liver resection in large HCC, the pooled RR for morbidity [RR(95%CI) = 1.00(0.76-1.31)] and mortality [RR(95%CI) = 1.15(0.73-1.80)] were not significant. Within the spectrum of BCLC B and C lesions, tumors greater than 10 cm were reported to have median 5-year OS of 33.0% and multifocal lesions 54.0%.CONCLUSION Indication for surgical resection should be extended to BCLC stage B lesions in selected patients. Further studies are needed to stratify stage C lesions for resection.Ye Xin Koh Hwee Leong Tan Weng Kit Lye Juinn Huar Kam Adrian Kah Heng Chiow Siong San Tan Su Pin Choo Alexander Yaw Fui Chung Brian Kim Poh Goh 2018World Journal of Hepatology2018,10,6:10
6Perfect forward secure identity-based authenticated key agreement protocol in the escrow mode显示文摘The majority of existing escrowable identity-based key agreement protocols only provide partial forward secrecy. Such protocols are, arguably, not suitable for many real-word applications, as the latter tends to require a stronger sense of forward secrecy—perfect forward secrecy. In this paper, we propose an efficient perfect forward-secure identity-based key agreement protocol in the escrow mode. We prove the security of our protocol in the random oracle model, assuming the intractability of the Gap Bilinear Diffie-Hellman (GBDH) problem.WANG ShengBao CAO ZhenFu CHENG ZhaoHui CHOO Kim-Kwang Raymond 2009Science in China(Series F)2009,52,8:9
7Iodized oil uptake assessment with cone-beam CT in chemoembolization of small hepatocellular carcinomas显示文摘AIM:To evaluate the utility of assessing iodized oil uptake with cone-beam computed tomography(CT)in transarterial chemoembolization(TACE)for small he-patocellular carcinoma(HCC).METHODS:Cone-beam CT provided by a biplane flat-panel detector angiography suite was performed on eighteen patients(sixteen men and two women;41-76 years;mean age,58.9 years)directly after TACE for small HCC(26 nodules under 30 mm;mean diam-eter,11.9 mm;range,5-28 mm).The pre-procedural locations of the tumors were evaluated using tripha-sic multi-detector row helical computed tomography(MDCT).The tumor locations on MDCT and the iodized oil uptake by the tumors were analyzed on cone-beam CT and on spot image directly after the procedures.RESULTS:All lesions on preprocedural MDCT were de-tected using iodized oil uptake in the lesions on cone-beam CT(sensitivity 100%,26/26).Spot image depictediodized oil uptake in 22 of the lesions(sensitivity 85%).The degree of iodized oil uptake was overestimated(9%,2/22)or underestimated(14%,3/22)on spot image in f ive nodules compared with that of cone-beam CT.CONCLUSION:Cone-beam CT is a useful and conve-nient tool for assessing the iodized oil uptake of small hepatic tumors(< 3 cm)directly after TACE.Ung Bae Jeon Jun Woo Lee Ki Seok Choo Chang Won Kim Suk Kim Tae Hong Lee Yeon Joo Jeong Dae Hwan Kang 2009World Journal of Gastroenterology2009,15,46:8
8Risk prediction of hepatitis B virus-related hepatocellular carcinoma in the era of antiviral therapy显示文摘Hepatocellular carcinoma(HCC)is a grave primary liver cancer that has a limited therapeutic option because it is generally diagnosed later in an advanced stage due to its aggressive biologic behavior.The early detection of HCC has a great impact on the treatment efficacy and survival of patients at high risk for cancer.Potential host,environmental,and virus-related risk factors have been introduced.Hepatitis B virus(HBV)is a major cause of end-stage liver diseases such as liver cirrhosis or HCC in endemic areas,and its serologic or virologic status is considered an important risk factor.HCC risk prediction derived from the identification of major risk factors is necessary for providing adequate screening/surveillance strategies to high-risk individuals.Several risk prediction models for HBV-related HCC have been presented recently with simple,efficient,and readily available to use parameters applicable to average-or unknown-risk populations as well as high-risk individuals.Predictive scoring systems of risk estimation to assess HCC development can provide the way to an evidence-based clinical approach for cost-and effort-effective outcomes,capable of inducing a personalized surveillance program according to risk stratification.In this review,the concepts and perspectives of the risk prediction of HCC are discussed through the analysis of several risk prediction models of HBV-related HCC.Il Han Song So Mi Kim Young Kwang Choo 2013World Journal of Gastroenterology2013,19,47:7
9Gastric peritoneal carcinomatosis-a retrospective review显示文摘AIM To characterize patients with gastric peritoneal carcinomatosis(PC) and their typical clinical and treatment course with palliative systemic chemotherapy as the current standard of care.METHODS We performed a retrospective electronic chart review of all patients with gastric adenocarcinoma with PC diagnosed at initial metastatic presentation between January 2010 and December 2014 in a single tertiary referral centre.RESULTS We studied a total of 271 patients with a median age of 63.8 years and median follow-up duration of 5.1 mo. The majority(n = 217, 80.1%) had the peritoneum as the only site of metastasis at initial presentation. Palliative systemic chemotherapy was eventually planned for 175(64.6%) of our patients at initial presentation, of which 171 were initiated on it. Choice of first-line regime was in accordance with the National Comprehensive Cancer Network Guidelines for Gastric Cancer Treatment. Thesepatients underwent a median of one line of chemotherapy, completing a median of six cycles in total. Chemotherapy disruption due to unplanned hospitalizations occurred in 114(66.7%), while cessation of chemotherapy occurred in 157(91.8%), with 42 cessations primarily attributable to PC-related complications. Patients who had initiation of systemic chemotherapy had a significantly better median overall survival than those who did not(10.9 mo vs 1.6 mo, P < 0.001). Of patients who had initiation of systemic chemotherapy, those who experienced any disruptions to chemotherapy due to unplanned hospitalizations had a significantly worse median overall survival compared to those who did not(8.7 mo vs 14.6 mo, P < 0.001).CONCLUSION Gastric PC carries a grim prognosis with a clinical course fraught with disease-related complications which may attenuate any survival benefit which palliative systemic chemotherapy may have to offer. As such, investigational use of regional therapies is warranted and required validation in patients with isolated PC to maximize their survival outcomes in the long run.Hwee Leong Tan Claramae Shulyn Chia Grace Hwei Ching Tan Su Pin Choo David Wai-Meng Tai Clarinda Wei Ling Chua Matthew Chau Hsien Ng Khee Chee Soo Melissa Ching Ching Teo 2017World Journal of Gastrointestinal Oncology2017,9,3:6
10A systematic literature review of blockchain cyber security显示文摘Since the publication of Satoshi Nakamoto's white paper on Bitcoin in 2008,blockchain has(slowly)become one of the most frequently discussed methods for securing data storage and transfer through decentralized,trustless,peer-to-peer systems.This research identifies peer-reviewed literature that seeks to utilize blockchain for cyber security purposes and presents a systematic analysis of the most frequently adopted blockchain security applications.Our findings show that the Internet of Things(IoT)lends itself well to novel blockchain applications,as do networks and machine visualization,public-key cryptography,web applications,certification schemes and the secure storage of Personally Identifiable Information(PII).This timely systematic review also sheds light on future directions of research,education and practices in the blockchain and cyber security space,such as security of blockchain in IoT,security of blockchain for AI data,and sidechain security.Paul J.Taylor Tooska Dargahi Ali Dehghantanha Reza M.Parizi Kim-Kwang Raymond Choo 2020Digital Communications and Networks2020,6,2:6
11A provable-secure and practical two-party distributed signing protocol for SM2 signature algorithm显示文摘Mobile devices are widely used for data access,communications and storage.However,storing a private key for signature and other cryptographic usage on a single mobile device can be challenging,due to its computational limitations.Thus,a number of(t,n)threshold secret sharing schemes designed to minimize private key from leakage have been proposed in the literature.However,existing schemes generally suffer from key reconstruction attack.In this paper,we propose an efficient and secure two-party distributed signing protocol for the SM2 signature algorithm.The latter has been mandated by the Chinese government for all electronic commerce applications.The proposed protocol separates the private key to storage on two devices and can generate a valid signature without the need to reconstruct the entire private key.We prove that our protocol is secure under nonstandard assumption.Then,we implement our protocol using MIRACL Cryptographic SDK to demonstrate that the protocol can be deployed in practice to prevent key disclosure.Yudi ZHANG Debiao HE Mingwu ZHANG Kim-Kwang Raymond CHOO 2020Frontiers of Computer Science2020,14,3:6
12Capecitabine with radiation is an effective adjuvant therapy in gastric cancers显示文摘AIM:To analyze the outcome of patients who received concurrent capecitabine(Xeloda) and radiation(XRT) compared to the established concurrent 5-fluorouracil(5-FU) with radiation(5FU-RT) and fluoropyrimidine-based chemotherapy alone as adjuvant treatment in gastric cancers.METHODS:All patients with gastric cancers who received adjuvant treatment at the National Cancer Centre Singapore between 1996 and 2006 were reviewed.Treatment outcomes of patients who received XRT were compared with those who had 5FU-RT or chemotherapy alone as adjuvant therapy for gastric cancers.RESULTS:A total of 108 patients were reviewed.Median age at diagnosis was 60.The majority of the patients(64.8%) had advanced stage Ⅲ and Ⅳ disease(with no distant metastasis).All except 4 patients had D2 gastrectomy.Twenty one patients(19.4%) had positive surgical resection margins.Thirty three patients received XRT compared with 52 who had 5FU-RT and 23 who received chemotherapy alone.For the patients in the chemotherapy-only group,all had fluoropyrimidine-based therapy,with added cisplatin in 7 patients and epirubicin in 2 patients.Median recurrence-free survival was longer for the XRT group(52 mo) compared to the 5FU-RT(35 mo) and chemotherapy-only groups(25 mo)(P=0.48).The patients in the XRT group achieved similar median overall survival(53 mo) as the 5FU-RT(54 mo) and the chemotherapy-only groups(44 mo)(P=0.5).CONCLUSION:Capecitabine with concurrent radiation was as effective as concurrent 5FU with radiation or fluoropyrimidine-based chemotherapy alone when used as adjuvant treatment in patients with gastric cancers.Chee Kian Tham Su Pin Choo Donald Yew Hee Poon Han Chong Toh Simon Yew Kuang Ong Sze Huey Tan Michael Lian Chek Wang Kian Fong Foo 2010World Journal of Gastroenterology2010,16,29:6

15Treatment for gastric ‘indefinite for neoplasm/dysplasia' lesions based on predictive factors显示文摘BACKGROUND Gastric ‘indefinite for neoplasm/dysplasia'(IFND) is a borderline lesion that is difficult to diagnose as either regenerative or neoplastic. There is a need for guidance in the identification of a subset of patients, who have an IFND lesion with a higher risk of malignant potential, to enable risk stratification and optimal management.AIM To determine the clinical and pathologic factors for the accurate diagnosis of gastric IFND lesions.METHODS In total, 461 gastric lesions diagnosed via biopsy as IFND lesions were retrospectively evaluated. Endoscopic resection(n = 134), surgery(n = 22), and follow-up endoscopic biopsy(n = 305) were performed to confirm the diagnosis.The time interval from initial biopsy to cancer diagnosis was measured, and diagnostic delays were categorized as > 2 wk, > 2 mo, > 6 mo, and > 1 year. The IFND lesions presenting as regenerating atypia(60%) or atypical epithelia(40%)at initial biopsy were adenocarcinomas in 22.6%, adenomas in 8.9%, and gastritis in 68.5% of the cases.RESULTS Four clinical factors [age ≥ 60 years(2.445, 95%CI: 1.305-4.580, P = 0.005),endoscopic size ≥ 10 mm(3.519, 95%CI: 1.891-6.548, P < 0.001), single lesion(5.702, 95%CI: 2.212-14.696, P < 0.001), and spontaneous bleeding(4.056, 95%CI:1.792-9.180, P = 0.001)], and two pathologic factors [atypical epithelium(25.575,95%CI: 11.537-56.695, P < 0.001], and repeated IFND diagnosis [6.022, 95%CI:1.822-19.909, P = 0.003)] were independent risk factors for gastric cancer. With two or more clinical factors, the sensitivity and specificity for carcinoma were91.3% and 54.9%, respectively. Ten undifferentiated carcinomas were initially diagnosed as IFND. In the subgroup analysis, fold change(5.594, 95%CI: 1.458-21.462, P = 0.012) predicted undifferentiated or invasive carcinoma in the submucosal layers or deeper. Diagnostic delays shorter than 1 year were not associated with worse prognoses. Extremely well-differentiated adenocarcinomas accounted for half of the repeated IFND cases and resulted in low diagnostic accuracy even on retrospective blinded review.CONCLUSION More than two clinical and pathologic factors each had significant cut-off values for gastric carcinoma diagnosis; in such cases, endoscopic resection should be considered.Mi Jung Kwon Ho Suk Kang Hyeon Tae Kim Jin Woo Choo Bo Hyun Lee Sung Eun Hong Kun Ha Park Dong Min Jung Hyun Lim Jae Seung Soh Sung Hoon Moon Jong Hyeok Kim Hye-Rim Park Soo Kee Min Jin won Seo Ji-Young Choe 2019World Journal of Gastroenterology2019,25,4:4
16Milan criteria are useful predictors for favorable outcomes in hepatocellular carcinoma patients undergoing liver transplantation after transarterial chemoembolization显示文摘AIM: To evaluate whether the Milan criteria are useful in patients with hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE) before liver transplantation (LT). METHODS: Thirty-six HCC patients who fulfilled the Milan criteria after having received TACE and subsequently underwent LT were included (TACE + LT group) in the study. As controls, 21 patients who also met the Milan criteria and underwent LT without prior treatment were selected (LT group). Post-LT clinical outcomes, such as HCC recurrence, survival rate, and histologic features of explanted livers, were compared between the two groups. RESULTS: Baseline characteristics were not different between the two groups. Pre-LT maximal tumor diameter in TACE + LT group was similar to that of LT group (2.0 ± 0.6 cm vs 2.3 ± 0.9 cm; P = 0.10). Post-LT histologic findings also revealed similar maximal tumor diameter in the two groups (2.4 ± 1.4 cm vs 2.3 ± 0.9 cm; P = 0.70). Explanted livers showed similar incidence of unfavorable pathologic features. The morality within 60 d after transplantation was not different between the two groups (8.3% vs 9.5%; P = 0.99). Post-LT 5-year survival rate (57% vs 74%; P = 0.70) and cumulative recurrence rate (8.3% vs 4.8%; P = 0.90) were not significantly different between the two groups. CONCLUSION: The Milan criteria are still a useful selec- tion criteria showing favorable outcomes in HCC patientsreceiving TACE before LT.Do Young Kim Moon Seok Choi Joon Hyoek Lee Kwang Cheol Koh Seung Woon Paik Byung Chul Yoo Sung Wook Shin Sung Wook Choo Young Soo Do Jong Chul Rhee 2006World Journal of Gastroenterology2006,12,43:4
17稀碱预处理棕榈残渣制备纤维乙醇显示文摘以棕榈残渣(Empty fruit bunch,EFB)为原料,通过预处理、酶解、发酵等过程制备纤维乙醇。首先对比了碱、碱/过氧化氢等预处理条件对棕榈残渣组成及酶解的影响,结果表明稀碱预处理效果较好。适宜的稀碱预处理条件为:NaOH浓度为1%,固液比为1∶10,在40℃浸泡24 h后于121℃下保温30 min,在该条件下,EFB的固体回收率为74.09%,纤维素、半纤维素和木质素的含量分别为44.08%、25.74%和13.89%。对该条件下预处理后的固体样品,以底物浓度5%、酶载量30 FPU/g底物酶解72 h,纤维素和半纤维素的酶解率分别达到84.44%和89.28%。进一步考察了酶载量和底物浓度对酶解的影响以及乙醇批式同步糖化发酵,当酶载量为30 FPU/g底物,底物浓度由5%增加至25%时,利用酿酒酵母Saccharomyces cerevisiae(接种量为5%,V/V)发酵72 h后乙醇的浓度分别为9.76 g/L和35.25 g/L,可分别达到理论得率的79.09%和56.96%。张海燕 周玉杰 李晋平 戴玲妹 刘德华 张建安 Yuen May Choo Soh Kheang Loh 2013生物工程学报2013,29,4:4
18SecBCS: a secure and privacy-preserving blockchain-based crowdsourcing system显示文摘A robust and scalable crowd management infrastructure is crucial in addressing operational challenges when deploying high-density sensors and actuators in a smart city. While crowdsourcing is widely used in crowd management, conventional solutions, such as Upwork and Amazon Mechanical Turk, generally depend on a trusted third-party platform. There exist several potential security concerns(e.g., sensitive leakage, single point of failure and unfair judgment) in such a centralized paradigm. Hence, a recent trend in crowdsourcing is to leverage blockchain(a decentralized ledger technology) to address some of the existing limitations. A small number of blockchain-based crowdsourcing systems(BCSs) with incentive mechanisms have been proposed in the literature, but they are generally not designed with security in mind. Thus, we study the security and privacy requirements of a secure BCS and propose a concrete solution(i.e., SecBCS)with a prototype implementation based on JUICE.Chao LIN Debiao HE Sherali ZEADALLY Neeraj KUMAR Kim-Kwang Raymond CHOO 2020Science China(Information Sciences)2020,63,3:4
19A microscale optical implant for continuous in vivo monitoring of intraocular pressure显示文摘Intraocular pressure(IOP)is a key clinical parameter in glaucoma management.However,despite the potential utility of daily measurements of IOP in the context of disease management,the necessary tools are currently lacking,and IOP is typically measured only a few times a year.Here we report on a microscale implantable sensor that could provide convenient,accurate,ondemand IOP monitoring in the home environment.When excited by broadband near-infrared(NIR)light from a tungsten bulb,the sensor’s optical cavity reflects a pressure-dependent resonance signature that can be converted to IOP.NIR light is minimally absorbed by tissue and is not perceived visually.The sensor’s nanodot-enhanced cavity allows for a 3–5 cm readout distance with an average accuracy of 0.29 mm Hg over the range of 0–40 mm Hg.Sensors were mounted onto intraocular lenses or silicone haptics and secured inside the anterior chamber in New Zealand white rabbits.Implanted sensors provided continuous in vivo tracking of short-term transient IOP elevations and provided continuous measurements of IOP for up to 4.5 months.Jeong Oen Lee Haeri Park Juan Du Ashwin Balakrishna Oliver Chen David Sretavan Hyuck Choo 2017Microsystems & Nanoengineering2017,3,1:4
20碱木质素过氧化氢预处理制备驱油剂的研究显示文摘探索了碱木质素经H2O2预处理,再经磺化、胺化、烷基化合成驱油用表面活性剂的方法。首先考察了过氧化氢预处理条件对表面张力的影响。结果表明,当过氧化氢与碱木质素质量比为1∶10,温度70℃,处理时间30 min效果较好,经该条件预处理后合成的表面活性剂质量分数为0.9%时,表面张力降至24 mN/m。进一步考察碱、表面活性剂质量分数对孤岛原油油/水界面张力的影响,并与同条件下未经预处理合成的表面活性剂的油/水界面张力对比,结果表明,碱木质素经预处理合成的表面活性剂质量分数为0.4%时,与质量分数为0.4%NaOH复配后可使最低油/水界面张力达0.07 mN/m,较未经氧化预处理组稳定时间明显延长。红外光谱(FT-IR)分析表明了碱木质素改性前后结构的变化。申士成 周玉杰 米杰 张建安 戴玲妹 刘德华 CHOO Y M LOH S K 2014林产化学与工业2014,34,1:4
