1Successes and challenges in non-destructive testing of aircraft composite structures显示文摘Composite materials are increasingly used in the aerospace industry.To fully realise the weight saving potential along with superior mechanical properties that composites offer in safety critical applications,reliable Non-Destructive Testing(NDT)methods are required to prevent catastrophic failures.This paper will review the state of the art in the field and point to highlight the success and challenges that different NDT methods are faced to evaluate the integrity of critical aerospace composites.The focus will be on advanced certificated NDT methods for damage detection and characterization in composite laminates for use in the aircraft primary and secondary structures.Hossein TOWSYFYAN Ander BIGURI Richard BOARDMAN Thomas BLUMENSATH 2020Chinese Journal of Aeronautics2020,33,3:19
2Clinical and molecular features of young-onset colorectal cancer显示文摘Colorectal cancer(CRC) is one of the leading causes of cancer related mortality worldwide. Although young-onset CRC raises the possibility of a hereditary component, hereditary CRC syndromes only explain a minority of young-onset CRC cases. There is evidence to suggest that young-onset CRC have a different molecular profile than late-onset CRC. While the pathogenesis of young-onset CRC is well characterized in individuals with an inherited CRC syndrome, knowledge regarding the molecular features of sporadic young-onset CRC is limited. Understanding the molecular mechanisms of young-onset CRC can help us tailor specific screening and management strategies. While the incidence of late-onset CRC has been decreasing, mainly attributed to an increase in CRC screening, the incidence of young-onset CRC is increasing. Differences in the molecular biology of these tumors and low suspicion of CRC in young symptomatic individuals, may be possible explanations. Currently there is no evidence that supports that screening of average risk individuals less than 50 years of age will translate into early detection or increased survival. However, increasing understanding of the underlying molecular mechanisms of young-onset CRC could help us tailor specific screening and management strategies. The purpose of this review is to evaluate the current knowledge about young-onset CRC, its clinicopathologic features, and the newly recognized molecular alterations involved in tumor progression.Veroushka Ballester Shahrooz Rashtak Lisa Boardman 2016World Journal of Gastroenterology2016,22,5:9

5Colonoscopy surveillance for high risk polyps does not always prevent colorectal cancer显示文摘AIM To determine the frequency and risk factors for colorectal cancer(CRC) development among individuals with resected advanced adenoma(AA)/traditional serrated adenoma(TSA)/advanced sessile serrated adenoma(ASSA). METHODS Data was collected from medical records of 14663 subjects found to have AA, TSA, or ASSA at screening or surveillance colonoscopy. Patients with inflammatory bowel disease or known genetic predisposition for CRC were excluded from the study. Factors associated with CRC developing after endoscopic management of high risk polyps were calculated in 4610 such patients who had at least one surveillance colonoscopy within 10 years following the original polypectomy of the incident advanced polyp. RESULTS84/4610(1.8%) patients developed CRC at the polypectomy site within a median of 4.2 years(mean 4.89 years), and 1.2%(54/4610) developed CRC in a region distinct from the AA/TSA/ASSA resection site within a median of 5.1 years(mean 6.67 years). Approximately, 30%(25/84) of patients who developed CRC at the AA/TSA/ASSA site and 27.8%(15/54) of patients who developed CRC at another site had colonoscopy at recommended surveillance intervals. Increasing age; polyp size; male sex; right-sided location; high degree of dysplasia; higher number of polyps resected; and piecemeal removal were associated with an increased risk for CRC developmentat the same site as the index polyp. Increasing age; right-sided location; higher number of polyps resected and sessile endoscopic appearance of the index AA/TSA/ASSA were significantly associated with an increased risk for CRC development at a different site. CONCLUSION Recognition that CRC may develop following AA/TSA/ASSA removal is one step toward improving our practice efficiency and preventing a portion of CRC related morbidity and mortality.Mohamad A Mouchli Lidia Ouk Marianne R Scheitel Alisha P Chaudhry Donna Felmlee-Devine Diane E Grill Shahrooz Rashtak Panwen Wang Junwen Wang Rajeev Chaudhry Thomas C Smyrk Ann L Oberg Brooke R Druliner Lisa A Boardman 2018World Journal of Gastroenterology2018,24,8:5

7Clinical disease registries in acute myocardial infarction显示文摘Disease registries,containing systematic records of cases,have for nearly 100 years been valuable in exploring and understanding various aspects of cardiology. This is particularly true for myocardial infarction,where such registries have provided both epidemiological and clinical information that was not readily available from randomised controlled trials in highlyselected populations. Registries,whether mandated or voluntary,prospective or retrospective in their analysis,have at their core a common study population and common data definitions. In this review we highlight how registries have diversified to offer information on epidemiology,risk modelling,quality assurance/improvement and original research-through data mining,transnational comparisons and the facilitation of enrolment in,and follow-up during registry-based randomised clinical trials.Reza Ashrafi Hussain Hussain Robert Brisk Leanne Boardman Clive Weston 2014World Journal of Cardiology2014,6,6:2

15Fiber guiding at the Dirac frequency beyond photonic bandgaps显示文摘Light trapping within waveguides is a key practice of modern optics,both scientifically and technologically.Photonic crystal fibers traditionally rely on total internal reflection(index-guiding fibers)or a photonic bandgap(photonic-bandgap fibers)to achieve field confinement.Here,we report the discovery of a new light trapping within fibers by the so-called Dirac point of photonic band structures.Our analysis reveals that the Dirac point can establish suppression of radiation losses and consequently a novel guided mode for propagation in photonic crystal fibers.What is known as the Dirac point is a conical singularity of a photonic band structure where wave motion obeys the famous Dirac equation.We find the unexpected phenomenon of wave localization at this point beyond photonic bandgaps.This guiding relies on the Dirac point rather than total internal reflection or photonic bandgaps,thus providing a sort of advancement in conceptual understanding over the traditional fiber guiding.The result presented here demonstrates the discovery of a new type of photonic crystal fibers,with unique characteristics that could lead to new applications in fiber sensors and lasers.The Dirac equation is a special symbol of relativistic quantum mechanics.Because of the similarity between band structures of a solid and a photonic crystal,the discovery of the Dirac-point-induced wave trapping in photonic crystals could provide novel insights into many relativistic quantum effects of the transport phenomena of photons,phonons,and electrons.Kang Xie Wei Zhang Allan D Boardman Haiming Jiang Zhijia Hu Yong Liu Ming Xie Qiuping Mao Lei Hu Qian Li Tianyu Yang Fei Wen Erlei Wang 2015Light(Science & Applications)2015,4,1:1
