Background: The presence of pathological Q waves in the infarct leads on the surface electrocardiogram in an ST-elevation acute myocardial infarction indicates myocardial necrosis. Clinically it might be difficult to ascertain the onset of acute myocardial infarction. Our aim was to assess whether the presence or absence of Q waves at presentation could be used as an indicator of the duration of acute myocardial infarction and predict mortality. Meth.d.: 15 222 patients with ST-elevation acute myocardial infarction and normal intraventricular conduction were randomly assigned streptokinase and aspirin plus bivalirudin or unfractionated heparin in the hERO-2 trial; randomisation did not alter 30-day mortality. 10 244 patients(67%) h.d.Q waves in the infarct territory at the time of randomisation, and 4978(33%) did not. The primary endpoint was 30-day mortality. Findings: There were more deaths at 30 days in patients with initial Q waves than in those without(1044[10%] vs 344[7%], phese findings were similar in patients with a first acute myocardial infarction and when stratified by time to randomisation(0-2, >2-4, >4 h) and by acute myocardial infarction location(anterior or inferior). Both the presence of initial Q waves and time to randomisation were positive univariate predictors, but only the presence of initial Q waves independently predicted 30-day mortality on multivariate analysis(adjusted OR 1.44, 95%CI 1.25-1.65 with clinical indices, and 1.31, 1.12-1.54 with clinical plus ST indices included as predictors). Interpretation: The presence of Q waves in the infarct leads at presentation of ST-elevation acute myocardial infarction independently predicts higher 30-day mortality in patients treated with fibrinolytic therapy. Therefore, a more aggressive approach to reperfusion might be warranted in these patients.

随着计算机硬件技术的日益发展,计算成像学中的光场成像技术(Light-field Imaging)已被成功应用于许多领域之中。光场三维粒子图像测速(Light-field Particle Image Velocimetry, LF-PIV)是一种利用单相机拍摄获取三维流场的新兴测试技术。对比较为成熟的多相机层析三维粒子图像测速技术(Tomographic PIV),其利用单相机的特点使其具有安装校准便捷、对光学窗口数量要求小等优势,故尤其适用于受限空间中的测量。本文将主要介绍光场三维粒子图像测速在两个应用场景中的实验结果,即超声速射流(Supersonic JetFlow)和线性叶栅流(Linear Cascade Flow)。在超声速射流测量中,将其结果与二维PIV以及纹影测量结果做了对比分析,表明光场PIV能够较好的还原空气中超声速条件下的流动特征;对线性叶栅尾缘附近不同叶高处的流场测量结果表明,其捕获到了吸力面分离涡随着攻角变化的变化,观测到了在不同叶高处截面流场的特征变化。两个实验的结果验证了光场PIV在复杂实验工况下的可行性。

In health, emotions are integrated with autonomic bodily responses. Emotional stimuli elicit changes in somatic (including autonomic) bodily states, which feedback to influence the expression of emotional feelings. In patients with spinal cord injury (SCI), this integration of emotion and bodily arousal is partially disrupted, impairing both efferent generation of sympathetic responses and afferent sensory feedback of visceral state via the spinal cord. A number of theoretical accounts of emotion predict emotional deficits in SCI patients, particularly at the level of emotional feelings, yet evidence for such a deficit is equivocal. We used functional MRI (fMRI) and a basic emotional learning paradigm to investigate the expression of emotion- related brain activity consequent upon SCI. We scanned seven SCI patients and seven healthy controls during an aversive fear conditioning task. Subjects viewed randomized presentations of four angry faces. One of the faces (CS + arm) was associated with.d.livery of electrical shock to the upper arm on 50% of trials. This shock was painful to all subjects. A face of the same gender acted as a ‘ safe’ control stimulus (CS- arm). In both control subjects and SCI patients, painful cutaneous stimulation of the arm evoked enhanced activity within components of a central pain matrix, including dorsal anterior cingulate, right insula and medial temporal lobe. however, SCI patients differed from controls in conditioning- related brain activity. SCI patients showed a relative enhancement of activity within dorsal anterior cingulate, periaqueductal grey matter (PAG) and superior temporal gyrus. Conversely, SCI patients showed relative attenuation of activity in subgenual cingulate, ventromedial prefrontal and posterior cingulate cortices to threat of painful arm stimulation (CS + arm >CS- arm). Our findings provide evidence for differences in emotion- related brain activity in SCI patients. We suggest that the observed functional abnormal

Tilted global solar irradiance in Bahrain: an experimental study

CLEAN ENERGY 2024年第2期8卷 27-34页

作者： Vasilikos, N. Georgantopoulou, C. Alajaimi, h. Almajed, S. h. Ahmed, M. Mathioulakis, d. Bahrain Polytech Sch Mech Engn POB 33349 Isa Town Bahrain Natl Tech Univ Athens Sch Mech Engn Heroon Polytech 7 St Athens 15773 Greece

In the present work, tilted global solar irradiance data are presented and analysed, measured for a period of 1 year on the campus of Bahrain Polytechnic, Kingdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis solar tracker. The fixed panel faces south with an angle of 26 degrees with respect to the horizontal, coinciding with the local geographical latitude. The second panel is moved by two motors, controlled by a global positioning system and suitable software so that the Sun's rays are perpendicular to the panel surface. A pyranometer is installed on each panel, recording the tilted global solar irradiance, stored by using a data logger. The analysis of the data obtained shows a 33% solar energy gain on an annual basis for the moving panel (2780 versus 2088 kWh/m2 on the fixed panel). More importantly, in June, when the energy demand in Bahrain is elevated due to the increased residential cooling loads, the solar energy received by the moving panel is 54.7% higher compared with that of the fixed panel. On a percentage basis, the increase in solar energy from the moving panel is profound in the early morning and late evening hours. Moreover, the reduction in the solar energy received by the fixed panel from May to June does not appear in the moving panel because of the adjustable orientation of the latter. Throughout the year, the mean daily solar power varies between 0.37 and 0.56 kW/m2 for the fixed panel, and 0.45 and 0.70 kW/m2 for the moving panel. In winter, solar energy fluctuations are elevated due to erratic weather conditions that present a peak standard deviation of 28% of the corresponding mean. The data presented are useful for potential solar investments in Gulf countries. Tilted global solar irradiance data are measured and analysed for a period of 1 year on the campus of Bahrain Polytechnic, Kingdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis solar tracker.
