1Determinants of the impact of blood pressure variability on neurological outcome after acute ischaemic stroke显示文摘Introduction: Increased blood pressure variability (BPV) is detrimental after acute ischaemic stroke, but the interaction between BPV and neuroimaging factors that directly influence stroke outcome has not been explored. Methods: We retrospectively reviewed inpatients from 2007 to 2014 with acute anterior circulation ischaemic stroke, CT perfusion and angiography at hospital admission, and a modified Rankin Scale (MRS) 30- 365 days after stroke onset. BPV indices included SD, coefficient of variation and successive variation of the systolic blood pressure between 0 and 120 hours after admission. Ordinal logistic regression models were fitted to MRS with predictor variables of BPV indices. Models were further stratified by CT perfusion volumetric measurements, proximal vessel occlusion and collateral score. Results: 110 patients met the inclusion criteria. The likelihood of a 1-point rise in the MRS increased with every 10 mm Hg increase in BPV (OR for the 3 BPV indices ranged from 2.27 to 5.54), which was more pronounced in patients with larger ischaemic core volumes (OR 8.37 to 18.0) and larger hypoperfused volumes (OR 6.02 to 15.4). This association also held true for patients with larger mismatch volume, proximal vessel occlusion and good collateral vessels. Conclusions: These results indicate that increased BPV is associated with worse neurological outcome after stroke, particularly in patients with a large lesion core volume, concurrent viable ischaemic penumbra, proximal vessel occlusion and good collaterals. This subset of patients, who are often not candidates for or fail acute stroke therapies such as intravenous tissue plasminogen activator or endovascular thrombectomy, may benefit from interventions aimed at reducing BPV.Adam de Havenon Alicia Bennett Gregory J Stoddard Gordon Smith Lee Chung Steve O’Donnell J Scott McNally David Tirschwell Jennifer J Majersik 2017Stroke & Vascular Neurology2017,2,1:6
2Characterisation of a microwave induced plasma torch for glass surface modification显示文摘Microwave induced plasma torches find wide applications in material and chemical analysis.Investigation of a coaxial electrode microwave induced plasma(CE–MIP)torch is conducted in this study,making it available for glass surface modification and polishing.A dedicated nozzle is designed to inject secondary gases into the main plasma jet.This study details the adaptation of a characterisation process for CE–MIP technology.Microwave spectrum analysis is used to create a polar plot of the microwave energy being emitted from the coaxial electrode,where the microwave energy couples with the gas to generate the plasma jet.Optical emission spectroscopy analysis is also employed to create spatial maps of the photonic intensity distribution within the plasma jet when different additional gases are injected into it.The CE–MIP torch is experimentally tested for surface energy modification on glass where it creates a super-hydrophilic surface.Adam BENNETT Nan YU Fengzhou FANG Marco CASTELLI Guoda CHEN Alessio BALLERI Takuya URAYAMA 2021Frontiers of Mechanical Engineering2021,16,1:2

4Design of a motorised plasma delivery system for ultra-precision large optical fabrication显示文摘A unique plasma figuring(PF)process was created and demonstrated at Cranfield University for manufacturing extremely large telescopes.The atmospheric pressure processing is faster and more cost-effective than other finishing processes;thus,providing an important alternative for large optical surfaces.The industrial scale manufacturing of thousands of ultra-precision metre-scale optics requires a robust PF machine:this requirement is achieved by making the plasma delivery system(PDS)performance repeatable.In this study,a dedicated PDS for large optical manufacturing was proposed to meet the industrial requirement.The PDS is based on an L-type radiofrequency(RF)network,a power supply,and an inductively coupled plasma torch.However,the complexities of these technologies require an in depth understanding of the integrated components that from the PDS.A smart control system for the modified PDS was created.This novel control system aims to make the characterization process deterministic:by automating the tuning of critical electrical components in the RF network,which is achieved by the use of in-line metrology.This paper describes the main design aspects.The PDS was tested with a good correlation between capacitance and RF frequencies.The robust PDS design enables a stable discharge of plasma with a low deviation of RF signals during the total15 hours’test.Hui Zhou Adam Bennett Marco Castelli Renaud Jourdain Jiang Guo Nan Yu 2020International Journal of Extreme Manufacturing2020,2,4:2

7Investigation of a plasma delivery system for optical figuring process显示文摘Plasma figuring process enables the correction of metre-scale optical surfaces,which has advantages such as rapid convergence to ultra-precision accuracy level,no subsurface damage,ease of upscale thanks to the conditions of operation at atmospheric.Such attributes make plasma figuring a highly competitive technology.To maintain a stable discharge of plasma for long period,a robust Plasma Delivery System(PDS)is required for large optics manufacturing.A dedicated PDS,mainly based on an L-type radio frequency(RF)network and an inductively coupled plasma(ICP)torch,had been previously proposed and designed.This study addresses the requirement for improving the robustness and securing the performance of the plasma etching.Due to the complexity of interactions of PDS parameters,single variable optimization is conducted for adjusting the impedance of the plasma torch.The PDS optimization is analysed based on ignition power demand,test repeatability and reflected power values.The results show that reflected power values are controllable within 10 W,when the RF power is supplied from 200 W up to 800 W.Finally,plasma processing is carried out on fused silica glass,using the optimum parameters of the PDS.Nan YU Renaud JOURDAIN Marco CASTELLI Adam BENNETT Jiang GUO Chengyu MA Fengzhou FANG 2021Chinese Journal of Aeronautics2021,34,4:1
