| 1 | Hyperspectral anomaly detection:a performance comparison of existing techniques显示文摘Anomaly detection in Hyperspectral Imagery(HSI)has received considerable attention because of its potential application in several areas.Numerous anomaly detection algorithms for HSI have been proposed in the literature;however,due to the use of different datasets in previous studies,an extensive performance comparison of these algorithms is missing.In this paper,an overview of the current state of research in hyperspectral anomaly detection is presented by broadly dividing all the previously proposed algorithms into eight different categories.In addition,this paper presents the most comprehensive comparative analysis to-date in hyperspectral anomaly detection by evaluating 22 algorithms on 17 different publicly available datasets.Results indicate that attribute and edge-preserving filtering-based detection(AED),local summation anomaly detection based on collaborative representation and inverse distance weight(LSAD-CR-IDW)and local summation unsupervised nearest regularized subspace with an outlier removal anomaly detector(LSUNRSORAD)perform better as indicated by the mean and median values of area under the receiver operating characteristic(ROC)curves.Finally,this paper studies the effect of various dimensionality reduction techniques on anomaly detection.Results indicate that reducing the number of components to around 20 improves the performance;however,any further decrease deteriorates the performance. | Noman Raza Shah Abdur Rahman M.Maud Farrukh Aziz Bhatti Muhammad Khizer Ali Khurram Khurshid Moazam Maqsood Muhammad Amin | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
| 2 | 急性冠状动脉综合征患者使用冠状动脉介入治疗的性别差异:来自澳大利亚墨尔本一家大型城市医院的经验显示文摘目的 :本研究旨在验证急性冠状动脉综合征(ACS)患者使用冠状动脉介入治疗的性别差异。方法 :对墨尔本一家大型城市医院2009-2012年住院的2096例ACS患者数据库进行了回顾性分析。ACS包括不稳定型心绞痛(UA)、ST段抬高型心肌梗死(STEMI)和非ST段抬高型心肌梗死(NSTEMI)。结果 :患者的平均年龄为64.3岁,其中624例(30%)为女性。一半病例被诊断为NSTEMI,23%的病例为STEMI,25%的病例为UA。与男性患者相比,女性患者入院时年龄较大,诊断为STEMI的比例较低,吸烟率较低;在严重共存病或使用冠状动脉造影方面,未观察到性别差异。诊断为STEMI的病例中,女性患者接受血管成形术支架的比例比男性患者低39%(调整OR=0.61,95%可信区间为0.39~0.96);接受冠状动脉旁路移植术的比例比男性患者低66%(调整OR=0.34,95%可信区间为0.13~0.93)。诊断为NSTEMI的病例中,女性患者接受冠状动脉旁路移植术的比例比男性患者低44%(调整OR=0.56,95%可信区间为0.37~0.83)。35~49岁的年轻病例中,女性患者接受血管成形术支架的比例低于男性患者;50岁以上的年长病例中,女性患者接受冠状动脉旁路移植术的比例低于男性患者。结论 :坚持以指南为基础的治疗,将有助于确保知识从指南到临床实践的转换。在进一步的研究中,调查临床表现,根据性别对ACS进行无创性检查和医学干预,也许可以更深入地解释冠状动脉介入治疗的性别差异。 | Linda Worrall-Carter Andrew MacI saac Elizabeth Scruth Muhammad Aziz Rahman | 2017 | 中国护理管理2017，17，2： | 0 |
| 3 | Seed Priming and Foliar Supplementation withβ-aminobutyric Acid Alleviates Drought Stress through Mitigation of Oxidative Stress and Enhancement of Antioxidant Defense in Linseed(Linum usitatissimum L.)显示文摘Drought is one of the critical limitations to agricultural soils and crop plants.Scarcity of water is increasing due to climate change that lead to increasing threats to global food security.Therefore,ecofriendly and cost effective strategies are highly desirable for mitigating drought stress along with sustainable and smart agricultural production.The aim of the study was to mitigate DS using seed priming and exogenous supplementation ofβ-aminobutyric acid(BABA)in linseed(Linum usitatissimum L.).Different doses(0,50,100 and 150μM)of BABA were used for seed priming agent and foliar spraying under three soil moisture levels viz.,25%(SM25),45%(SM45)and 65%(SM65).The response variables of both experiments included different agro-botanical traits and oxidative stress indicators such as melondialdehyde content,free proline accumulation,and antioxidant defense in plants.The linseed plants showed water stress at SM25 that reduced plant height,number of branches per plant,time taken to flower initiation and heading,and root and shoot dry weights.Additionally,the number of capsules and seeds per capsule showed a significant decline at SM25,which led to a drastic reduction in 100-seed weight yield in linseed plants in both experiments.However,seed priming and foliar supplementation with of BABA(50–100μM)significantly improved these morpho-agronomical attributes in linseed plants under DS.The results revealed that the BABA was fully active in linseed plants at SM25.Interestingly,the combination of SM25 with BABA significantly improved the antioxidant enzymes superoxide dismutase(SOD),catalase(CAT),ascorbate peroxidase(APX),and peroxidase(POD)activity,which significantly enhanced DS tolerance in linseed plants.These findings might be useful to oil seed breeders and farmers linseed for breeding program in linseed plants as well as sustainable agricultural production of oil seed crop plants. | Tauqeer Ahmad Yasir Muhammad Ateeq Allah Wasaya Mubshar Hussain Naeem Sarwar Khuram Mubeen Mudassir Aziz Muhammad Aamir Iqbal Chukwuma COgbaga Ibrahim Al-Ashkar Md Atikur Rahman Ayman El Sabagh | 2023 | Phyton-International Journal of Experimental Botany2023，92，11： | 0 |
| 4 | The quality of older adults'involvement in clinical communication with general practitioners:evidence from rural towns in Australia显示文摘Objective:A study was conducted about the putative links of older rural Australians'health knowledge and preparation with their quality of involvement in patient-general practitioner(GP)communication during health intake visits.Methods:It was a cross-sectional study between January 2021 and April 2022.The 32-item quality of involvement in communication scale was designed and incorporated into the SurveyGizmo software.This online survey was administered by sending an email request to the Renmark Rotary Club,which actively promoted this study across five rural towns in South Australia.121 participants completed the surveys.Mean-sum scores were calculated based on the questionnaire responses to evaluate outcomes,specifically initiation of information,active participation,and emotional expression.We employed different methods including t-tests,ANOVA,and leaner regressions to analyse data.Results:The demographic profile of participants characterised by a female predominance(58.7%,71/121),a majority falling within the 65-<70 age bracket(47.1%,57/121),and a high level of educational attainment(58.7%had completed high school or higher,71/121).Additionally,35%of the participants predominantly spoke a language other than English at home.Regarding the initiation of information with GPs,the mean sum-score was(20.5+3.7),indicating a marginally above-average level of engagement.Contrarily,the active participation was suboptimal,as suggested by a mean sum score of(35.9±6.3).Furthermore,the emotional expression was relatively low,with a mean score of(13.9±1.8).Substantial variations were discerned in the quality of patient-GP communication,contingent upon factors such as educational background,language spoken at home,health literacy,and preparatory measures for clinical visits.Participants who predominantly spoke a language other than English at home demonstrated significantly lower levels of information initiation with their GPs(P<0.o01).Higher educational attainment was positively correlated with increased active participation(P<0.001).Enhanced health literacy and thorough visit preparation were significantly associated with increased levels of active participation(P<0.001).Conclusion:Meaningful engagement through recognition,empowerment,and support(health literacy programs)for older rural adults is suggested for improving their quality of involvement in communication with GPs. | Mohammad Hamiduzzaman Noore Siddiquee Harry James Gaffney Muhammad Aziz Rahman Jennene Greenhill | 2023 | Global Health Journal2023，7，4： | 0 |
