灵智的竞争才是美丽的生命——试论石涛的"一画"论     

张绍华 《和田师范专科学校学报》2006,26(5):107-109

石涛的画论思想实是中国绘画美学的一总结形态,但其在总结的基础上鲜明地提出了绘画乃是出自于“心”的创造,是艺术家主体精神无限拓展的产物,因为只有灵智的竞争才是美丽的生命。  相似文献

《心是孤独的猎者》是卡森.麦卡勒斯的名著之一。通过对一个有很多悲微小人物的小镇的描写,麦卡勒斯表现了现代社会中的人的精神孤独感。而其时缓时急、时快时慢的独特叙事方式节奏更体现出其小说的艺术价值。  相似文献   

Troponin T and Heart Type Fatty Acid Binding Protein (h-Fabp) as Biomarkers in Patients Presenting with Chest Pain     

Lakshmi Lavanya Reddy  Swarup A. V. Shah  Alpa J. Dherai  Chandrashekhar K. Ponde  Tester F. Ashavaid 《Indian journal of clinical biochemistry : IJCB》2016,31(1):87-92

Acute coronary syndrome (ACS) is a term for a range of clinical signs and symptoms suggestive of myocardial ischemia. It results in functional and structural changes and ultimately releasing protein from injured cardiomyocytes. These cardiac markers play a major role in diagnosis and prognosis of ACS. This study aims to assess the efficacy of heart type fatty acid binding protein (h-FABP) as a marker for ACS along with the routinely used hs-TropT. In our observational study, plasma h-FABP (cut-off 6.32 ng/ml) and routinely done hs-Trop T (cutoff 0.1 and 0.014 ng/ml) were estimated by immunometric laboratory assays in 88 patients with acute chest pain. Based on the clinical and laboratory test findings the patients were grouped into ACS (n = 41) and non-ACS (n = 47). The diagnostic sensitivity, specificity, NPV, PPV and ROC curve at 95 % CI were determined. Sensitivity of hs-TropT (0.1 ng/ml), hs-TropT (0.014 ng/ml) and h-FABP were 53, 86 and 78 % respectively and specificity for the same were 98, 73 and 70 % respectively. Sensitivity, specificity and NPV calculated for a cut-off combination of hs-TropT 0.014 ng/ml and h-FABP was 100, 51 and 100 % respectively. These results were substantiated by ROC analysis. Measurement of plasma h-FABP and hs-TropT together on admission appears to be more precise predictor of ACS rather than either hs-Trop T or h-FABP.  相似文献   

论“艺术的心”     

陈剑 《楚雄师范学院学报》2011,26(2):68-74

"艺术的心"是丰子恺艺术教育思想中的一个重要概念。在阐述"艺术的心"含义的基础上详细分析了它的三个基本特征——绝缘、同情、慈悲,指出"艺术的心"是审美之心、道德之心、宗教之心三者的融合,然后梳理了"艺术的心"的理论渊源,并将其放在中国现代艺术教育的总体背景中探讨它的理论价值。  相似文献

《西游记》中的观音“疥癞”形象源流考     

高美茹 《鸡西大学学报》2011,11(1):105-106

《西游记》第八回中观音为寻取经人,幻化模样后的人间形象是一个满身病疮的,衣衫褴褛的落魄和尚。在人们心目中法相庄严的观音怎么会幻化成这样一副模样？这绝不是信手拈来的自由发挥,而是有着文献依据的。通过一连串相互继连的记载可以考证出其源流。  相似文献   

An efficient method of addressing ectopic beats: new insight into data preprocessing of heart rate variability analysis     

Wen F  He FT 《Journal of Zhejiang University. Science. B》2011,12(12):976-982

Heart rate variability (HRV) analysis is affected by ectopic beats. An efficient method was proposed to deal with the ectopic beats. The method was based on trend correlation of the heart timing signal. Predictor of R-R interval (RRI) value at ectopic beat time was constructed by the weight calculation and the slope estimation of preceding normal RRI. The type of ectopic beat was detected and replaced by the predictor of RRI. The performance of the simulated signal after ectopic correction was tested by the standard value using power spectrum density (PSD) estimation, whereas the results of clinical data with ectopic beats were compared with the adjacent ectopic-free data. The result showed the frequency indexes after ectopy corrected had less error than other methods with the test of simulated signal and clinical data. It indicated our method could improve the PSD estimation in HRV analysis. The method had advantages of high accuracy and real time properties to recover the sinus node modulation.  相似文献
