We study non-overlapping axis-parallel packings of 3D boxes with profits into a dedicated bigger box where rotation is either forbidden or permitted, and we wish to maximize the total profit. Since this optimization problem is NP-hard, we focus on approximation algorithms. We obtain fast and simple algorithms for the non-rotational scenario with approximation ratios 9 ＋ ε and 8 ＋ ε, as well as an algorithm with approximation ratio 7 ＋ ε that uses more sophisticated techniques; these are the smallest approximation ratios known for this problem. Furthermore, we show how the used techniques can be adapted to the case where rotation by 90° either around the z-axis or around all axes is permitted, where we obtain algorithms with approximation ratios 6 ＋ ε and 5 ＋ ε, respectively. Finally our methods yield a 3D generalization of a packability criterion and a strip packing algorithm with absolute approximation ratio 29/4, improving the previously best known result of 45/4.

China's energy security is becoming of ever greater concern to the government and the Communist Party, as there is no replacement for oil which is crucial for high growth rates and raising living standards of the common population to legitimize the rule of the party. Yet, oil not only runs the civilian industry and large parts of the country's infrastructure but also the military, providing a strong base for cooperation between both *** state-ownership of the military-industrial complex and the oil-companies, together with China's stance on non-interference and willingness to project its interests abroad, both parties have a strong rationale for cooperation out of structural and interest-based reasons. This thesis examines the points of connection upon a convergence of interests within the greater setting of China's national interests and the structure of decision-mak-ing in foreign policy making based on network theories and ideas of neo-idealism. Hav-ing a rationale, preconditions and structure for a military-energy cooperation established, it is evident that China's management of its bilateral ties and protection of interests within the current status quo further such cooperation as China is a late-comer on the interna-tional energy markets and so has to deal with weak governments where other oil-majors do not invest, and the need for keeping relations on a pragmatic, friendly and mutually beneficial level. This requires ever higher investments to satisfy the needs of the govern-ments concerned, which in many cases is about sanctioned or embargoed goods such as arms. However, this materialization of bilateral ties in terms of investment-flux and infra-structure projects in order to alter the structure of the current status quo in China's favor is determined by China's capacity to deal with externalities further abroad, intensity of market forces and the wider international setting that may, if China doesn't open its pro-tection of interests as global comm

AIM: To analyze the cellular immune response towards microsatellite-instability(MSI)-induced frameshift-peptides(FSPs) in patients suffering from inflammatory bowel disease(IbD) with and without thiopurine-based immunosuppressive ***: Frequencies of peripheral blood T cell responses of IbD patients(n = 75) against FSPs derived from 14 microsatellite-containing candidate genes were quantified by interferon-γ enzyme-linked immunospot.T cells derived from 20 healthy individuals served as ***: Significant T cell reactivities against MSIinduced FSPs were observed in 59 of 75 IbD patients(78.7%).This was significantly more as we could observe in 20 healthy controls(P = 0.001).Overall,the reactivity was significantly influenced by thiopurine treatment(P = 0.032) and duration of disease(P = 0.002) but not by duration or cumulative amount of thiopurine therapy(P = 0.476).Unexpected,15 of 24(62.5%) IbD patients without prior thiopurine treatment also showed increased FSP-specific immune responses(P = 0.001).CONCLUSION: These findings propose FSPs as potential novel class of inflammation-associated antigens and this in turn may have implications for screening,diagnosis as well as clinical management of patients suffering from IbD and other inflammatory conditions.

随着社会的不断进步,电力已经成为人们生活中不可缺少的一部分,它对电力系统的安全性和可靠性提出了更高的要求。在电力系统中,可能一个很小的电力故障会造成大面积的停电事故,给经济的发展造成不可估量的损失。因此可靠的电力系统故障分析是有效解决电力系统故障的重要的依据。发生故障的因素很多,如电力系统设备故障或者决策错误,以及闪电或者洪水等自然灾害。电力系统数据越来越多,这些数据经常包括很多重要的信息,这些信息将有助于进行电力系统分析。近几年,机器学习是很流行的一个研究方向,具有很强大的计算能力。通过机器学习训练神经网络,研究电力系统数据特征提取和系统故障分析。本论文研究用卷积神经网络提取不同系统结构的电力系统数据的特征,仿真结果让我们更好的理解如何用深入学习来分析电力系统故障。仿真研究了数据训练卷积神经网络,这些数据来自不同故障情景(包括故障时间、类型、位置),以及不同负荷和发电情况。使用Matlab和Simulink创建数据样本,用小波分解提取故障分析的重要的频率,为了利用数据监督机器学习,用滑动窗口方法来创建“有故障”或“没有故障”的样本数据。

Several new treatment options for gastric cancer have been introduced but the prognosis of patients diagnosed with gastric cancer is still poor. Disease prognosis could be improved for high-risk individuals by implementing earlier screenings. because many patients are asymptomatic during the early stages of gastric cancer,the diagnosis is often delayed and patients present with unresectable locally advanced or metastatic disease. Cytotoxic treatment has been shown to prolong survival in general,but not all patients are responders. The application of targeted therapies and multimodal treatment has improved prognosis for those with advanced ***,these new therapeutic strategies do not uniformly benefit all *** whether patients will respond to specific therapies would be of particular value and would allow for stratifying patients for personalized treatment *** imaging by positron emission tomography was the first technique with the potential to predict the response of esophagogastric cancer to neoadjuvant *** and validating tissue-based biomarkers are ongoing *** this review,we discuss the status of several targeted therapies for gastric cancer,as well as proteomic and metabolic methods for investigating biomarkers for therapy response prediction in gastric cancer.
