1薄板激光焊时失稳变形及其控制显示文摘对薄板激光焊时出现的失稳变形进行了试验研究,利用CCD记录和观察0.8 mm和1.5 mm两种厚度的不锈钢板焊接过程中典型的动态变形行为,这种变形行为既包括变形量的大小又包括变形的方向;根据两种厚度薄板表现出的不同变形行为,分析了各自发生失稳的机理。采用冷却水为介质的背面动态冷却方法对失稳变形进行控制,通过对冷热源距离d和冷却水流量q两个主要冷却参数的优化,在有无拘束两种条件下分别得到了0.8 mm和1.5 mm薄板良好的变形控制效果。同时讨论了合理拘束对失稳变形的影响。温鹏 张旭东 陈武柱 Henry Peng 2006焊接学报2006,27,9:21
2Outcomes of combination MRI-targeted and transperineal template biopsy in restaging low-risk prostate cancer for active surveillance显示文摘Objective:Active surveillance(AS)offers a strategy to reduce overtreatment and now is a widely accepted treatment option for low-risk prostate cancer.An ideal tool for risk-stratification would detect aggressive cancers and exclude such men from taking up AS in the first place.We evaluate if a combination of transperineal template biopsy with magnetic resonance imaging(MRI)-targeted biopsy identifies significant prostate cancer amongst men initially diagnosed with low-risk prostate cancer.Methods:This prospective,single-blinded study included men with low-risk prostate cancer(D’Amico’s Criteria)diagnosed on conventional transrectal ultrasound-guided biopsy.Patients first underwent multiparametric MRI of the prostate6 weeks after initial biopsy.Each suspicious lesion is mapped and assigned a Prostate Imaging Reporting and Data System(PIRADS)score.Template biopsy is first performed with the surgeon blinded to MRI findings followed by MRI-targeted biopsy using a robotic transperineal biopsy platform.Results:The age of the 19 men included is 65.4±4.9 years(mean±SD).Prostate specific antigen(PSA)at diagnosis and at the time of transperineal biopsy were comparable(7.3±1.7 ng/mL and 7.0±1.8 ng/mL,p Z 0.67),so were prostate volumes(34.2±8.9 mL and 32.1±13.4 mL,p Z 0.28).MRI-targeted biopsy had a higher percentage of cancer detection per core compared to template biopsy(11.7%vs.6.5%,p Z 0.02),this was more than 3 times superior for Gleason 7 disease(5.9%vs.1.6%,p<0.01).Four of 18(22.2%)patients with MRI lesions had significant disease with MRI-targeted biopsy alone.Three of 19 patients(15.8%)had significant disease with template biopsy alone.In combination,both techniques upclassified five patients(26.3%),all of whom underwent radical prostatectomy.Whole mount histology confirmed tumour location and grade.All six patients with PIRADS 5 lesions had cancer detected(66.6%significant disease).Conclusion:A combination of MRI-targeted and template biopsy may optimally risk-classify“low-risk”patients diagnosed on initial conventional transrectal ultrasonography(TRUS)prostate biopsy.Kenneth Chen Kae Jack Tay Yan Mee Law Hakan Aydin Henry Ho Christopher Cheng John Shyi Peng Yuen 2018Asian Journal of Urology2018,5,3:2

6High-throughput physical phenotyping of cell differentiation显示文摘In this report,we present multiparameter deformability cytometry(m-DC),in which we explore a large set of parameters describing the physical phenotypes of pluripotent cells and their derivatives.m-DC utilizes microfluidic inertial focusing and hydrodynamic stretching of single cells in conjunction with high-speed video recording to realize high-throughput characterization of over 20 different cell motion and morphology-derived parameters.Parameters extracted from videos include size,deformability,deformation kinetics,and morphology.We train support vector machines that provide evidence that these additional physical measurements improve classification of induced pluripotent stem cells,mesenchymal stem cells,neural stem cells,and their derivatives compared to size and deformability alone.In addition,we utilize visual interactive stochastic neighbor embedding to visually map the high-dimensional physical phenotypic spaces occupied by these stem cells and their progeny and the pathways traversed during differentiation.This report demonstrates the potential of m-DC for improving understanding of physical differences that arise as cells differentiate and identifying cell subpopulations in a label-free manner.Ultimately,such approaches could broaden our understanding of subtle changes in cell phenotypes and their roles in human biology.Jonathan Lin Donghyuk Kim Henry T.Tse Peter Tseng Lillian Peng Manjima Dhar Saravanan Karumbayaram Dino Di Carlo 2017Microsystems & Nanoengineering2017,3,1:1
7Multiparametric MRI reporting using Prostate Imaging Reporting and Data System version 2.0 (PI-RADSv2) retains clinical efficacy in a predominantly post-biopsy patient population显示文摘Objective:To evaluate the efficacy of multiparametric magnetic resonance imaging(mp-MRI)using Prostate Imaging Reporting and Data System version 2.0(PI-RADSv2)definitions in detecting organ-confined prostate cancer.Methods:All patients who underwent radical prostatectomy between January 1,2014 and December 30,2014 were identified.All underwent mp-MRI within 180 days before surgery.Those with prior pelvic irradiation or androgen deprivation therapy were excluded.Fully embedded,whole-mount histopathology was centrally reviewed and correlated with imaging for tumour location,Gleason score(GS)and stage.Results:There were 39 patients included,of which 35(90%)had mp-MRI done post-biopsy.A total of 93 cancer foci were identified on whole-mount pathology,of which mp-MRI detected 63(68%).Of those detected by mp-MRI,14 were PI-RADS 3(n=6 for GS 6,n=8 for GS 7,no GS≥8)and 49 were PI-RADS 4e5(nZ7 for GS 6,nZ33 for GS 7,and nZ9 for GS≥8).There were 30(32%)cancer foci missed by mp-MRI(n=15 for GS 6,n=13 for GS 7 and n=2 for GS≥8).A lesion classified as PI-RADS 4e5 predicted a higher grade cancer on pathology as compared to PI-RADS 3(for GS 7 lesions,odds ratio[OR]=3.53,95%CI:0.93e13.45,p=0.064).The mp-MRI size detection limit was 20 mm2 and 100 mm2 for 50%and 75%probability of cancer,respectively.In associating with radiological and pathologic stage,the weighted Kappa value was 0.69(p<0.0001).The sensitivity and positive predictive values for this study were 68%(95%CI:57%e77%)and 78%(95%CI:67%e86%),respectively.Conclusion:In this predominantly post-biopsy cohort,mp-MRI using PI-RADSv2 reporting has a reasonably high diagnostic accuracy in detecting clinically significant prostate cancer.Edwin Jonathan Aslim Yan Mee Law Puay Hoon Tan John Carson Allen Jr Lionel Tim-Ee Cheng Viswanath Anand Chidambaram Li Yan Khor Benjamin Yongcheng Tan Ernest Wencong Eu Christopher Wai Sam Cheng John Shyi Peng Yuen Henry Sun Sien Ho Lui Shiong Lee 2019Asian Journal of Urology2019,6,3:1
8Isolated blunt iliac artery injury successfully treated with endovascular stent显示文摘Common or external iliac artery injury due to blunt trauma is unusual without an associated pelvic fracture.Here we report on a 62 years old man that sustained left external iliac artery thrombosis due to blunt trauma following fall from motorbike.There was no immediate circulatory compromise.Contrasted CT of abdomen revealed an associated left lower abdominal wall traumatic hernia.The iliac artery was intervened with an endovascular stent to restore luminal flow and the hernia was repaired electively.The entire clinical course and management dilemma are described in this article.Ee Peng Lee Tan Jih Huei Tan Chor Lip Henry Bakin Salinawati Mohamad Yuzaidi Imran Alwi Rizal 2022Chinese Journal of Traumatology2022,25,4:1
9Recent advances on iron-catalyzed coupling reactions involving organolithium reagents显示文摘Owing to their inexpensive and environmentally friendly properties,iron-based catalysts have been actively investigated for new organic reactions.In this account,we summarized our recent results on iron-catalyzed cross-coupling reactions and homo-coupling reactions.With iron-based catalysts,we constructed diverse carbon-carbon bonds,i.e.,C(sp^2)-C(sp^3),C(sp^3)-C(sp^3),C(sp^3)-C(sp^2)and C(sp^2)-C(sp^2)bonds.In order to demonstrate the usefulness of our iron protocol,we also carried out these reactions on gram-scale reactions,leading to good yields.Zhuliang Zhong Xiao-Shui Peng Henry N.C.Wong 2019Chinese Chemical Letters2019,30,8:1

12High‑accuracy measurement of Compton scattering in germanium for dark matter searches显示文摘Compton scattering with bound electrons contributes to a significant atomic effect in low-momentum transfer,yielding background structures in direct light dark matter searches as well as low-energy rare event experiments.We report the measurement of Compton scattering in low-momentum transfer by implementing a 10-g germanium detector bombarded by a^(137)Cs source with a radioactivity of 8.7 mCi and a scatter photon captured by a cylindrical NaI(Tl)detector.A fully relativistic impulse approximation combined with multi-configuration Dirac–Fock wavefunctions was evaluated,and the scattering function of Geant4 software was replaced by our calculation results.Our measurements show that the Livermore model with the modified scattering function in Geant4 is in good agreement with the experimental data.It is also revealed that atomic many-body effects significantly influence Compton scattering for low-momentum transfer(sub-keV energy transfer).Hai‑Tao Jia Shin‑Ted Lin Shu‑Kui Liu Hsin‑Chang Chi Muhammed Deniz Chang‑Hao Fang Peng Gu Xi Jiang Yi‑Ke Shu Qian‑Yun Li Yu Liu Ren‑Ming‑Jie Li Chen‑Kai Qiao Chang‑Jian Tang Henry Tsz‑King Wong Hao‑Yang Xing Li‑Tao Yang Qian Yue Yu‑Lu Yan Kang‑Kang Zhao Jing‑Jun Zhu 2022Nuclear Science and Techniques2022,33,12:1

15Adaptive evolution to the natural and anthropogenic environment in a global invasive crop pest,the cotton bollworm显示文摘The cotton bollworm,Helicoverpa armigera,is set to become the most economically devastating crop pest in the world,threatening food security and biosafety as its range expands across the globe.Key to understanding the eco-evolutionary dynamics of H.armigera,and thus its management,is an understanding of population connectivity and the adaptations that allow the pest to establish in unique environments.We assembled a chromosome-scale reference genome and re-sequenced 503 individuals spanning the species range to delineate global patterns of connectivity,uncovering a previously cryptic population structure.Minghui Jin Henry L.North Yan Peng Hangwei Liu Bo Liu Ruiqing Pan Yan Zhou Weigang Zheng Kaiyu Liu Bo Yang Lei Zhang Qi Xu Samia Elfekih Wendy A.Valencia-Montoya Tom Walsh Peng Cui Yongfeng Zhou Kenneth Wilson Chris Jiggins Kongming Wu Yutao Xiao 2023The Innovation2023,4,4:0
