Multi-tensor Completion for Estimating Missing Values in Video Data

Many tensor-based data completion methods aim to solve image and video in-painting problems. But, all methods were only developed for a single dataset. In most of real applications, we can usually obtain more than one dataset to reflect one phenomenon, and all the datasets are mutually related in some sense. Thus one question raised whether such the relationship can improve the performance of data completion or not? In the paper, we proposed a novel and efficient method by exploiting the relationship among datasets for multi-video data completion. Numerical results show that the proposed method significantly improve the performance of video in-painting, particularly in the case of very high missing percentage

A Closed-loop Cross-Layer Scheme for Wireless Multiuser Transmissions

AbstractTo improve transmission efficiency of wireless communication systems, cross-layer design is investigated, which can adapt to the dynamically variable wireless channel characters. In this paper, a novel cross-layer design for multi-user system is proposed to improve system performance. The Beamforming-MIMO cross-layer system is scheduled through combining multilevel adaptive modulation (AM) at physical layer with truncated automatic repeat request (ARQ) protocol at data link layer, and feed backing modulation mode, ARQ request and transmit weight vector from receiver, in order to improve multi-antennas system performance. This paper derives close-form expressions of the system spectral efficiency and the outage probability for wireless multiuser MIMO transmissions. It shows by simulation that, compared to Alamouti's cross-layer system and SISO cross-layer system, this cross-layer system can achieve better performance. And we analyze the impact of the transmit antenna number and mobile user number on the performance

The Construction and implementation of Evaluation Management Systems in Finance Engineering Major and Its Enlightenment

In finance engineering major, student status management is an important component of universities. It can supervise the quality assessment and management of the learning and performance of undergraduate students, from entrance to graduation, and it reflects universities teaching management in a scientific, standardized, systematic level, as well as it establishes a stable teaching order and provides guarantee to achieve the goal of teaching and personnel training. Based on the analysis of the current situation of student status management systems of China and international universities, this paper discusses design, implementation strategies and guarantee measures of status management systems

Building environment assessment methods and social studies of rural villages in Yunnan and urban development in Chongqing City, Southwest China

Recent urbanization processes and corresponding government policies in China have highlighted the need for much greater understanding of sustainable development and the requirements for sustainability in settings that are very different in rural and urban regions. This paper examines practice and knowledge linked to typical vernacular houses constructed since 1950 in Yunnan Province and regional buildings in Chongqing City in Southwest China. Both areas have played crucial roles in contributing to regional architectural design since the beginning of the 20th Century because of the diversity arising from numerous ethnic groups and various climate types and topography features in the region. The study explores how academic and end-user knowledge accumulated and developed, and how this has revealed social, cultural and political influences on how designers and consumers were motivated towards sustainable design over the same time period. It is argued that locally shared knowledge bases should be considered important for informing governmental policies, planning strategy and consumers’ preferences, as well as influencing actions and social acceptance in relation to sustainable development. Furthermore, sustainable design should not be regarded as a contemporary new idea, but one that has its roots in the historical changes in built environment design and practice

An Improved PageRank Method based on Genetic Algorithm for Web Search

AbstractWeb search engine has become a very important tool for finding information efficiently from the massive Web data. Based on PageRank algorithm, a genetic PageRank algorithm (GPRA) is proposed. With the condition of preserving PageRank algorithm advantages, GPRA takes advantage of genetic algorithm so as to solve web search. Experimental results have shown that GPRA is superior to PageRank algorithm and genetic algorithm on performance

Photothermally Induced Alkyl Radicals and Pyroptosis Synergistically Inhibit Breast Tumor Growth

Photothermal therapy (PTT) is an emerging local tumor ablation technique with clinical translation potential. After the NIR-II laser irradiates the tumor, the photothermal agent Hu-Kaiwen ink (Ink) converts light energy into hyperthermia and maintains the temperature at 42-45°C, thus achieving a low-temperature photothermal therapy. Alkyl radicals can kill tumor cells by overcoming the hypoxic microenvironment of the tumor. The photothermal reaction can induce the conversion of alkyl radicals from 2,2′-azobis[2-(2-imidazolin-2-yl) propane] dihydrochloride (AIPH) and thus have a synergistic tumor inhibition effect. the DNA methyltransferase inhibitor decitabine (DCT) can induce pyroptosis and cause inflammation and immune response to achieve systemic immunity. In this way, a synergistic combination of photothermal, alkyl radicals and pyroptosis could be used to kill breast tumor cells. Sodium alginate (ALG) was used as a carrier to form a hydrogel structure, which can improve the stability and duration of action of the mixed drugs. The significant tumor growth inhibitory effect of composite hydrogels has been demonstrated in both in vitro and ex vivo studies
