| 1 | Using the polymerase chain reaction coupled with denaturing gradient gel electrophoresis to investigate the association between bacterial translocation and systemic inflammatory response syndrome in predicted acute severe pancreatitis显示文摘AIM: To investigate the use of PCR and DGGE to investigate the association between bacterial translocation and systemic inflammatory response syndrome in predicted severe AP.METHODS: Patients with biochemical and clinical evidence of acute pancreatitis and an APACHE Ⅱ score ≥8 were enrolled. PCR and DGGE were employed to detect bacterial translocation in blood samples collected on d1,3, and 8 after the admission. Standard microbial blood cultures were taken when there was clinical evidence of sepsis or when felt to be clinically indicated by the supervising team.RESULTS: Six patients were included. Of all the patients investigated, only one developed septic complications;the others had uneventful illness. Bacteria were detected using PCR in 4 of the 17 collected blood samples. The patient with sepsis was PCR-positive in two samples (taken on d 1 and 3), despite three negative blood cultures. Using DGGE and specific primers, the bacteria in all blood specimens which tested positive for the presence of bacterial DNA were identified as E coli.CONCLUSION: Our study confirmed thatunlike traditional microbiological techniques, PCR can detect the presence of bacteria in the blood of patients with severe AP. Therefore, this latter method in conjunction with DGGE is potentially an extremely useful tool in predicting septic morbidity and evaluating patients with the disease. Further research using increased numbers of patients, in particular those patients with necrosis and sepsis, is required to assess the reliability of PCR and DGGE in the rapid diagnosis of infection in AP. | Callum B Pearce Vitaly Zinkevich Iwona Beech Viera Funjika Ana Garcia Ruiz Afraa Aladawi Hamish D Duncan | 2005 | World Journal of Gastroenterology2005，11，45： | 11 |

| 3 | All-silicon carrier accumulation modulator based on a lateral metal-oxide-semiconductor capacitor显示文摘In silicon photonics, the carrier depletion scheme has been the most commonly used mechanism for demonstrating high-speed electro-optic modulation. However, in terms of phase modulation efficiency, carrieraccumulation-based devices potentially offer almost an order of magnitude improvement over those based on carrier depletion. Previously reported accumulation modulator designs only considered vertical metal-oxidesemiconductor(MOS) capacitors, which imposes serious restrictions on the design flexibility and integratability with other photonic components. In this work, for the first time to our knowledge, we report experimental demonstration of an all-silicon accumulation phase modulator based on a lateral MOS capacitor. Using a Mach–Zehnder interferometer modulator with a 500-μm-long phase shifter, we demonstrate high-speed modulation up to 25 Gbit∕s with a modulation efficiency(V_πL_π) of 1.53 V·cm. | KAPIL DEBNATH DAVID J.THOMSON WEIWEI ZHANG ALI Z.KHOKHAR CALLUM LITTLEJOHNS JAMES BYERS LORENZO MASTRONARDI MUHAMMAD K.HUSAIN KOUTA IBUKURO FREOERIC Y.GARDES GRAHAM T,REED SHINICHI SAITO | 2018 | Photonics Research2018，6，5： | 6 |
| 4 | Ge-on-Si modulators operating at mid-infrared wavelengths up to 8 μm显示文摘We report mid-infrared Ge-on-Si waveguide-based PIN diode modulators operating at wavelengths of 3.8 and8 μm. Fabricated 1-mm-long electro-absorption devices exhibit a modulation depth of >35 dB with a 7 V forward bias at 3.8 μm, and a similar 1-mm-long Mach–Zehnder modulator has a Vπ· L of 0.47 V · cm. Driven by a 2.5 Vpp RF signal, 60 MHz on-off keying modulation was demonstrated. Electro-absorption modulation at 8 μm was demonstrated preliminarily, with the device performance limited by large contact separation and high contact resistance. | TIANTIAN LI MILOS NEDELJKOVIC NANNICHA HATTASAN WEI CAO ZHIBO QU CALLUM GLITTLEJOHNS JORDI SOLER PENADES LORENZO MASTRONARDI VINITA MITTAL DANIEL BENEDIKOVIC DAVID JTHOMSON FREDERIC YGARDES HEQUAN WU ZHIPING ZHOU GORAN ZMASHANOVICH | 2019 | Photonics Research2019，7，8： | 5 |
| 5 | Magnetic and superconducting phase diagrams and transition temperatures predicted using text mining and machine learning显示文摘Predicting the properties of materials prior to their synthesis is of great importance in materials science.Magnetic and superconducting materials exhibit a number of unique properties that make them useful in a wide variety of applications,including solid oxide fuel cells,solid-state refrigerants,photon detectors and metrology devices.In all these applications,phase transitions play an important role in determining the feasibility of the materials in question.Here,we present a pipeline for fully integrating data extracted from the scientific literature into machine-learning tools for property prediction and materials discovery.Using advanced natural language processing(NLP)and machine-learning techniques,we successfully reconstruct the phase diagrams of well-known magnetic and superconducting compounds,and demonstrate that it is possible to predict the phase-transition temperatures of compounds not present in the database.We provide the tool as an online open-source platform,forming the basis for further research into magnetic and superconducting materials discovery for potential device applications. | Callum J.Court Jacqueline M.Cole | 2020 | npj Computational Materials2020，，1： | 4 |

| 7 | Pathways of flower infection and pollen-mediated dispersion of Pseudomonas syringae pv. actinidiae, the causal agent of kiwifruit bacterial canker显示文摘Flowers can provide a protected and nutrient-rich environment to the epiphytic microflora,thus representing a sensible entry point for pathogens such as Pseudomonas syringae pv.actinidiae(Psa).This bacterium can colonize both male and female Actinidia flowers,causing flower browning and fall,and systemic invasion of the host plant,eventually leading to its death.However,the process of flower colonization and penetration into the host tissues has not yet been fully elucidated.In addition,the presence of Psa in the pollen from infected flowers,and the role of pollination in the spread of Psa requires confirmation.The present study employed a Psa strain constitutively expressing the fluorescent GFPuv protein,to visualize in vivo flower colonization.Microscopy observations were performed by means of confocal laser scanning and wide-field fluorescent microscopy,and were coupled with the study of Psa population dynamics by quantitative PCR(q-PCR).The pathogen was shown to colonize stigmata,move along the stylar furrow,and penetrate the receptacles via the style or nectarhodes.Once the receptacle was invaded,the pathogen migrated along the flower pedicel and became systemic.Psa was also able to colonize the anthers epiphytically and endophytically.Infected male flowers produced contaminated pollen,which could transmit Psa to healthy plants.Finally,pollinators(Apis mellifera and Bombus terrestris)were studied in natural conditions,showing that,although they can be contaminated with Psa,the pathogen’s transmission via pollinators is contrasted by its short survival in the hive. | Irene Donati Antonio Cellini Giampaolo Buriani Sofia Mauri Callum Kay Gianni Tacconi Francesco Spinelli | 2018 | Horticulture Research2018，5，1： | 3 |
| 8 | Remote monitoring of implantable defibrillators is associated with fewer inappropriate shocks and reduced time to medical assessment in a remote and rural area显示文摘BACKGROUND Implantable cardioverter defibrillators(ICDs)and cardiac resynchronisation therapy with defibrillators(CRT-D)reduce mortality in certain cardiac patient populations.However,inappropriate shocks pose a problem,having both adverse physical and psychological effects on the patient.The advances in device technology now allow remote monitoring(RM)of devices to replace clinic follow up appointments.This allows real time data to be analysed and actioned and this may improve patient care.AIM To determine if RM in patients with an ICD is associated with fewer inappropriate shocks and reduced time to medical assessment.METHODS This was a single centre,retrospective observational study,involving 156 patients implanted with an ICD or CRT-D,followed up for 2 years post implant.Both appropriate and inappropriate shocks were recorded along with cause for inappropriate shocks and time to medical assessment.RESULTS RM was associated with fewer inappropriate shocks(13.6%clinic vs 3.9%RM;P=0.030)and a reduced time to medical assessment(15.1±6.8 vs 1.0±0.0 d;P<0.001).CONCLUSION RM in patients with an ICD is associated with improved patient outcomes. | Kara Callum Claudia Graune Elizabeth Bowman Edward Molden Stephen J Leslie | 2021 | World Journal of Cardiology2021，13，3： | 2 |

| 10 | 人类增强的一次热带风暴对近岸珊瑚礁的影响显示文摘土地开发以其造成的土壤加速侵蚀和迁移所产生的水体悬浮物及沉积物而成为人类对珊瑚礁的最主要的威胁。我们研究了一次热带风暴后沉积物对圣卢西亚(St.Lucia)珊瑚礁群落的影响,发现最靠近大的河流河口的珊瑚礁沉积物比较多,珊瑚损失比较大。一些地点的珊瑚死亡率超过了50%,其死亡率和褪色的程度取决于当地的沉积物数量。尽管工程师们努力降低侵蚀率,我们仍然发现风暴来临时正在修建的公路附近的地点有更多的沉积物。我们的资料表明土地开发对珊瑚礁有很大的负效应。假如土地开发的需求不断增加,并且大西洋热带地区大风暴近来频繁,问题可能会进一步加剧。 | Joshua Sladek Nowlis Callum M.Roberts Allan H.Smith Erkki Siirila 裴晓菲 | 1997 | 人类环境杂志1997，26，8： | 2 |
| 11 | A review of phosphorus nutrition in irrigated cotton farming systems of Australia显示文摘Australian cotton production predominantly occurs on Vertisols.The average lint yield of cotton grown in Australia is 2260–2700 kg·hm^(−2),which is 2.5 to 3 times the world average.This high productivity per unit of land area requires efficient use of resources such as water and nutrients.However,high yields accelerate the export of nutrients such as phosphorus(P)in seed,depleting the soil reserves of P more than in other countries with lower cotton yields.Recent surveys of cotton industry indicate that P application rates should match seed P export(30~40 kg·hm−2),but historical depletion within subsoil is still evident and is continuing.Depletion of soil P is typically more pronounced in the subsoil than in the topsoil(0~20 cm)where P fertiliser is applied,as cotton roots rely on these layers as important sources of plant available water and available P.This mismatch between zones of P uptake and resupply may increase stratification of available P in the soil profile.Recent studies showed that cotton responded poorly to banded applications of fertiliser P,while dispersal of fertiliser throughout the plant beds was more successful.Researchers have also observed sporadic cotton responses to applied P fertiliser in soils where available P concentrations were well above the previously determined critical concentrations indicative of fertiliser P responses in Australia.To sustain highyielding cotton production in Australia,a greater understanding of cotton root acquisition of applied P,as well as a re-examination of critical soil P concentrations for each production region are required. | NACHIMUTHU Gunasekhar SCHWENKE Graeme MERCER Clarence BISCHOF Callum HULME Pat BELL Michael | 2022 | Journal of Cotton Research2022，5，1： | 2 |
| 12 | Addressing Frequency Control Challenges in Future Low-Inertia Power Systems:A Great Britain Perspective显示文摘The ambitious global targets on decarbonization present the need for massive integration of renewable generation in power systems,resulting in a significant decrease in the system inertia.In addition to the reduction in system inertia,the transmission system in Great Britain(GB)faces some unique challenges owing to its relatively small capacity,while being decoupled from other transmission systems and with the renewable resources largely non-uniformly distributed across the system.This paper presents opinions and insights on the challenges associated with frequency control in a low-inertia system and the potential solutions from a GB perspective.In this paper,we focus on three main techniques that act over different time scales:synchronous condensers,inertia emulation,and fast frequency response.We evaluate their relative advantages and limitations with learnings from recent research and development projects in GB,along with the opinions on their roles in addressing the frequency control challenges in future low-inertia systems. | Qiteng Hong Md Asif Uddin Khan Callum Henderson AgustíEgea-Àlvarez Dimitrios Tzelepis Campbell Booth | 2021 | Engineering2021，7，8： | 2 |
