目的前瞻性评价Z轴分辨力与管电流对普通CT结肠成像计算机辅助诊断（CAD）系统在猪结肠模型的息肉检出中的影响。方法在14个猪结肠模型上制造了96个息肉。在16层CT上扫描获得CT结肠影像，扫描准直器宽0．75mm，采用10、50、100与160mAs；螺矩为1．5。每扫描1mAs，CT影像重建厚度（ST）均为1．5mm，重建间隔（RI）为1．3mm。为评价Z轴空间分辨力的影响，还对100mAs的CT扫描用不同的ST（原文为SI，可能有误）与RI组合进行重建（分别为1．0与0．7mm，3．0与2．0mm，3．0与3．0mm．5．0与5．0mm）。随后用CAD程序分析模型数据。

Traumatic brain injury(TBI)is a public health problem with an undue economic burden that impacts nearly every age,ethnic,and gender group across the globe(Capizzi et al.,2020).TBIs are often sustained during a dynamic range of exposures to energetic environmental forces and as such outcomes are typically heterogeneous regarding severity and pathology(Capizzi et al.,2020).

There exists a great need for the development of high performance alloys due to increasing demands for energy conservation and environmental protection. Application of strip casting shows a strong potential for the improvement of properties of existing alloys and also for the development of novel alloy systems with superior properties. The present paper reviews our Center's activities in the development of high performance alloys by strip casting. Examples include (1) Al alloys, (2) wrought Mg alloys, and (3) bulk metallic glass (BMg) alloys.

Aluminum-doped zinc oxide (AZO) thin films were deposited on sapphire (002) and glass substrates by two different sputtering techniques radio frequency magnetron cosputtering of AZO and ZnO targets and sputtering of an AZO target. The dependence of the photoluminescence (PL) and transmittance properties of the AZO films deposited by cosputtering and sputtering on the AZO/ZnO target power ratio, R and the O2/Ar flow ratio, r were investigated, respectively. Only a deep level emission peak appears in the PL spectra of cosputtered AZO films whereas both UV emission and deep level emission peaks are observed in the PL spectra of sputtered AZO films. The absorption edges in the transmittance spectra of the AZO films shift to the lower wavelength region as R and r increase. Effects of crystallinity, surface roughness, PL on the transmittance of the AZO films were also explained using the X-ray diffraction (XRD), atomic force microscopy (AFM), and PL analysis results.
