图像加密技术是保护数字图像在通信传输和存储使用过程中免遭非法使用的基础性技术,在当今数字化时代它具有广泛的应用背景。目前已有的图像加密算法普遍基于混淆和扩散结构,这些算法在安全性和加密效率方面都存在不同程度的优化空间。为了进一步推进图像加密技术的研究,有必要探求多样化的高效且安全的图像加密算法。在本文中,我们提出了一种新的图像加密方法,该方法结合了交织Logistic映射(ILM)和轨道移位像素置乱方法(OSPSM)。所提出的加密方法应用OSPSM策略对图像像素进行混淆处理。这种方法借鉴了行星沿其轨道的旋转运动方式,结合混沌序列扰乱图像的像素位置。本文的加密方案由三个过程组成:(1)轨道移位置乱。通过随机选择最外层轨道的像素,并由于随机选择的像素的移动而开始轨道上像素的旋转移位,使轨道上所有像素都改变它们的位置。这个过程一直持续到最内侧轨道的最后一个像素完成移位。像素移位是根据密钥来改变其原始位置。通过这种方法,轨道上所有像素的位置被随机扰乱。(2)一维向量的循环置乱。将轨道移位后的像素矩阵转换成一维长向量,进一步使用ILM生成的密钥对一维向量的元素进行循环置乱位置;然后将置乱后的一维矢量转换为2D矩阵。(3)基于混沌掩模图像的像素值变换。对置乱后的二维矩阵实施扩散操作,扩散过程包含如下两个步骤:首先,使用ILM生成掩模图像。然后,将生成的掩模图像与置乱后的二维图像矩阵进行异或运算;于是得到最终的密文图像。实验结果、安全性评估以及与现有方法的比较表明,本文所提出的技术方案具有良好的加密效果,尤其是具有非常快的加密速度。因此,本文方案特别适用于需要对图像进行实时加密的应用场景。图23幅,表12个,参考文献84篇。

在可再生能源中,风能是使用最广泛的资源,因为它具有商业接受度、成本低、易于运行和维护、从概念到运行、创造新就业机会的时间相对较短、最少对环境的不利影响。风能行业的快速技术发展和多兆瓦级水平轴风力涡轮机的可用性进一步推动了全球风电利用的推广。众所周知,风速随着高度的增加而增加,因此能量输出也随之增加。然而,由于结构和其他问题,不能超过一定的高度。因此,需要进行其他尝试来提高风力涡轮机的效率,将轮毂高度保持在可接受和可控的范围内。通过修改和重新设计叶片来降低切入速度和/或额定速度,可以提高风力涡轮机的效率或能量输出。这可以通过确定优化参数(例如年发电量、功率系数、能量成本、叶片质量和叶片设计约束(例如物理、几何和空气动力学))来解决。在我们的工作中,我们将添加一个护罩/增强器来包裹“裸涡轮”,从而将效率提高到4-5%,这可以作为最经济的输入能源。

Structural geometry, electronic band gaps, density of states, optical and mechanical properties of double perovskite halides Cs2InBiX6(X = F, Cl, Br, I) are investigated using the density functional theory. These compounds possess genuine perovskite stoichiometry, evaluated using various geometry-based indices like tolerance factor, octahedral factor, and formation energy. The fundamental electronic band gaps are direct and valued in the range 0.80–2.79 e V. These compounds have narrow band gaps(except Cs2InBiX6) due to strong orbital coupling of the cations. The valence band maximum and conduction band minimum are confirmed to be essentially of In 5 s and Bi 6 p characters, respectively. The splitting of Bi 6 p bands due to strong spin-orbit coupling causes reduction in the band gaps. These compounds have large dispersion in their bands and very low carrier effective masses. The substitution of halogen atoms has great influence on the optical properties. The mechanical properties reveal that Cs2InBiX6(X = F, Cl, Br, I) satisfy the stability criteria in cubic structures.

Breast cancer is a frightful disease and serious concern in women around the world causing significant health care burden in both developed and developing countries. Extensive research work has shown that breast cancer provides strong resistance to chemical agents, U V radiation,and hormonal treatments. It is generally accepted that cell genetics is not the only main reason for breast cancer and genetic risk factors, for example, mutations in RRCAI and BRCA2 genes constitute 5%-10% of all breast cancer rates. Other related factors include age, gender,race, ethnicity, weight, reproductive factors, exo-and endogenous hormonal exposures, oral contraceptives use, ultraviolet radiation, diet, and night work(circadian disruption). Many studies have revealed that dietary isoflavones regulate breast cancer occurrence, recurrence and prognosis. Dietary isoflavones have long been part of Asian population diet and there is a significant increase as compared to dietary isoflavones intake among other populations. Dietary isoflavones are natural phytoestrogens having both estrogenic and anti-estrogenic potentials on breast cancer cells in culture, animal models and in experimental trials. This literature survey provides a comprehensive overview on the tumor preventive and tumor promoting potentials of dietary isoflavones on breast cancer. In addition, this paper provides a literature review of dietary isoflavones and their effects on up-regulation and down-regulation of different signaling pathways, genes and proteins. Finally, future perspectives of dietary isoflavones and breast cancer researchers are also critically discussed, which will provide a deeper insight regarding the inner molecular mechanisms of action.
