目的研究CT源性血流参数是否能够预测新辅助化疗在原发性乳腺癌中病理学的完全缓解(pCR)。方法 20例可能为原发性乳腺癌病人经过新辅助化疗(NAC)通过容积CT灌注经反卷积分析获得整个肿瘤区域的血流量(BF)、血容量(BV)和流量提取(FE)。如果病理学没有检测到肿瘤残留,即为病人获得病理学完全缓解。用Mann-WhitneyU检验研究BF、BV、FE、肿瘤的大小和数量与病理学完全缓解之间的基线关系。受试者操作特征曲线(ROC)分析是最能进行评估预测缓解的参数。用Bland-Altman法评估组内差异和组间差异率。结果完成4次新辅助化疗的20例病人中有17例实现了病理学完全缓解。实现病理学完全缓解者的BF和FE的基线高于没有实现病理学完全缓解者(P=0.032);肿瘤的大小和数量无明显的差异(P>0.05)。ROC分析表明,BF和FE能够有效地识别缓解者(AUC=0.87;P=0.03)。组内差异和组间差异率基本一致。结论原发性乳腺癌在治疗前容积CT表现出高灌注水平时,行新辅助化疗更可能获得完全性病理缓解。要点①CT源性血流参数可能对乳腺癌的治疗有帮助。②CT灌注有助于预测新辅助化疗对乳腺癌的疗效。③在病理学完全缓解者中,BF和FE的基线是较高的。

Road side barriers are constructed to protect passengers and contain vehicles when a vehicle crashes into a barrier. In general, full-scale crash testing needs to be carried out if a geometrically and structurally equivalent barrier has not previously been proven to meet the requirements of containing the vehicle and dissipating sufficient impact energy for passenger protection. As full-scale crash testing is very expensive, the number of data that can be measured in a test is usually limited, and it may not always be possible to obtain good quality measurements in such a test, a reliable and efficient numerical simulation of crash testing is therefore very useful. This paper presents finite element simulations of a 3-rail steel road traffic barrier under vehicle impact. The performance levels defined in Australian Standards AS5100 Clause 10.5 for these barriers are checked. The numerical simulations show that the barrier is able to meet low performance levels. However, the maximum deceleration is higher than the acceptable limit for passenger protection. If present, a kerb launches the vehicles into the barrier, allowing for the possibility of overriding the barrier under certain circumstances, but it redirects the vehicle and reduces the incident angle, which reduces impact force on the barrier. Further investigation into all common kerb profiles on roads should be carried out, as only one kerb profile is investigated in this study.

We review our recent efforts on developing HgCdSe infrared materials on Ga Sb substrates via molecular beam epitaxy(MBE) for fabricating next generation infrared detectors with features of lower production cost and larger focal plane array format size. In order to achieve high-quality HgCdSe epilayers, ZnTe buffer layers are grown before growing HgCdSe, and the study of misfit strain in ZnTe buffer layers shows that the thickness of ZnTe buffer layer needs to be below 300 nm in order to minimize the generation of misfit dislocations. The cut-off wavelength/alloy composition of HgCdSe materials can be varied in a wide range by varying the ratio of Se/Cd beam equivalent pressure during the HgCdSe *** temperature presents significant impact on the material quality of HgCdSe, and lower growth temperature leads to higher material quality for HgCdSe. Typically, long-wave infrared HgCdSe(x = 0.18, cut-off wavelength of 10.4 μm at 80 K) presents an electron mobility as high as 1.3×10~5cm^2·V^(-1)·s^(-1), a background electron concentration as low as 1.6×10^(16)cm^(-3), and a minority carrier lifetime as long as 2.2 μs. These values of electron mobility and minority carrier lifetime represent a significant improvement on previous studies of MBE-grown HgCdSe reported in the open literatures,and are comparable to those of counterpart HgCdTe materials grown on lattice-matched CdZnTe substrates. These results indicate that HgCdSe grown at the University of Western Australia, especially long-wave infrared can meet the basic material quality requirements for making high performance infrared detectors although further effort is required to control the background electron concentration to below 10^(15)cm^(-3). More importantly, even higher quality HgCdSe materials on GaSb are expected by further optimizing the growth conditions, using higher purity Se source material, and implementing postgrowth thermal annealing and defect/impurity gettering/filtering. Our results demonst
