An efficient quantum proactive incremental learning algorithm

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 49-57页

In scenarios where a large amount of data needs to be learned, incremental learning can make full use of old knowledge, significantly reduce the computational cost of the overall learning process, and maintain high performance. In this paper, taking the MaxCut problem as our example, we introduce the idea of incremental learning into quantum computing, and propose a Quantum Proactive Incremental Learning algorithm(QPIL). Instead of a one-off training of quantum circuit, QPIL contains a multi-phase training on gradually-increased subgraphs of all vertices, proactively reducing large-scale problems to smaller ones to solve in steps, providing an efficient solution for MaxCut. Specifically, some vertices and corresponding edges are randomly selected for training to obtain optimized parameters of the quantum circuit at first. Then, in each incremental phase, the remaining vertices and corresponding edges are gradually added and the parameters obtained from the previous phase are reused in the parameter initialization of the current phase. We perform experiments on 120 different small-scale graphs, and it shows that QPIL performs superior to prevalent quantum and classical baselines in terms of approximation ratio(AR), time cost, anti-forgetting, and solving stability. In particular, QPIL's AR surpasses 20% of mainstream quantum baselines, and the time cost is less than 1/5 of them. The idea of QPIL is expected to inspire efficient and high-quality solutions in large-scale Max Cut and other combinatorial optimization problems.

Based on strain-based design, high deformability X70 high strength pipeline steel with dual-phase microstructure has been developed, which can be laid in the seismic, the cold or the deepwater region. The results illustrated that the developed X70 steel has the stress-strain curve like round house and it shows good anti-transformation characteristic, high uniform deformation(≥10%), enhanced n-value(≥0.10), and the low yield-tensile ratio Y/T(≤0.85). The dual-phase microstructure of ferrite and bainite contained in the steel can be obtained by the advanced thermo-mechanical control process.

A Preliminary Study of ＂I＂ and ＂We＂ in Teachers＇ Talk in a Military Academy

引用

Sino-US English Teaching 2014年第10期11卷 783-790页

作者： ZHANG jing gao li ZHENG Zhen People's liberation Army University of Science and Technology Nanjing China

This paper is a qualitative study of how and why English teachers in military academy use personal pronoun I and inclusive and exclusive we. Through analysis of teachers＇ use of/and we in the taped videos, some differences in the frequency use of inclusive we and exclusive we have been found and a number of effects the inclusive pronouns create are illustrated. Specifically, the paper reveals how 1 and we help teachers create a sense of authority in the classroom, showing how teachers are aligning with the students. Inclusive pronouns can act as a positive politeness device by imparting knowledge, organizing the contents, and highlighting the important and difficult points. It is noticed that there is fuzziness between inclusive personal pronoun and exclusive pronoun, which can be manipulated by the teacher to create authority or closeness with students.

Neural Regeneration Research 2011年第4期6卷 304-308页

作者： Yonghong Yang Chengqi He lin Yang Qiang gao Shasha li jing He Department of Rehabilitation Medicine West China Hospital Sichuan University Key Laboratory of Rehabilitation Medicine of SichuanProvince Chengdu 610041 Sichuan Province China

Low-frequency electrical stimulation has resulted in favorable effects in the treatment of post-stroke dysphagia. However, the safety of cervical low-frequency electrical stimulation remains unclear because of numerous nerves and blood vessels in the neck. In the present study, rats with ischemic stroke underwent low-frequency electrical stimulation, and systemic and local effects of electrical stimulation at different densities and waveforms were investigated. Electrical stimulation resulted in no significant effects on body mass, liver or kidney function, or mortality rate. In addition, no significant adverse reaction was observed, despite overly high intensity of low-frequency electrical stimulation, which induced laryngismus, results from the present study suggested that it is safe to stimulate the neck with a low-frequency electricity under certain intensities.

Expression of PIN Genes in Rice （Oryza sativa L.）： Tissue Specificity and Regulation by Hormones

Molecular Plant 2009年第4期2卷 823-831页

作者： Ji-Rong Wang Han Hu gao-Hang Wang jing li Jie-Yu Chen Ping Wu State Key Laboratory of Plant Physiology and Biochemistry College of Life Sciences Zi Jin Gang Campus Zhejiang University Hangzhou 310058 People's Republic of China

Twelve genes of the PIN family in rice were analyzed for gene and protein structures and an evolutionary relationship with reported AtPINs in Arabidopsis. Four members of PIN1 （designated as OsPINla-d）, one gene paired with AtPIN2 （OsPIN2）, three members of PIN5 （OsPIN5a-c）, one gene paired with AtPIN8 （OsPIN8）, and three monocot-specific PINs （OsPIN9, OsPINIOa, and b） were identified from the phylogenetic analysis. Tissue-specific expression patterns of nine PIN genes among them were investigated using RT-PCR and GUS reporter. The wide variations in the expression domain in different tissues of the PIN genes were observed. In general, PIN genes are up-regulated by exogenous auxin, while different responses of different PIN genes to other hormones were found.

N6-methyladenosine(m^(6)A), the most prevalent and conserved RNA modification in eukaryotic cells, profoundly influences virtually all aspects of mRNA metabolism. mRNA plays crucial roles in neural stem cell genesis and neural regeneration, where it is highly concentrated and actively involved in these processes. Changes in m^(6)A modification levels and the expression levels of related enzymatic proteins can lead to neurological dysfunction and contribute to the development of neurological diseases. Furthermore, the proliferation and differentiation of neural stem cells, as well as nerve regeneration, are intimately linked to memory function and neurodegenerative diseases. This paper presents a comprehensive review of the roles of m^(6)A in neural stem cell proliferation, differentiation, and self-renewal, as well as its implications in memory and neurodegenerative diseases. m^(6)A has demonstrated divergent effects on the proliferation and differentiation of neural stem cells. These observed contradictions may arise from the time-specific nature of m^(6)A and its differential impact on neural stem cells across various stages of development. Similarly, the diverse effects of m^(6)A on distinct types of memory could be attributed to the involvement of specific brain regions in memory formation and recall. Inconsistencies in m^(6)A levels across different models of neurodegenerative disease, particularly Alzheimer's disease and Parkinson's disease, suggest that these disparities are linked to variations in the affected brain regions. Notably, the opposing changes in m^(6)A levels observed in Parkinson's disease models exposed to manganese compared to normal Parkinson's disease models further underscore the complexity of m^(6)A's role in neurodegenerative processes. The roles of m^(6)A in neural stem cell proliferation, differentiation, and self-renewal, and its implications in memory and neurodegenerative diseases, appear contradictory. These inconsistencies may be a

在已获得对同一目标场景的多个传感器观测图像的情况下,本文建立了一种基于概率模型的多尺度图像信息融合算法.其基本思想是:首先对每个传感器图像分别进行小波包多尺度分解变换,建立基于该传感器图像的塔式结构子图像集,并且在每个尺度上得到基于每个子图像像素的概率模型;然后在每个尺度上的对应像素处,基于来自不同传感器图像的多个对应像素值,利用最小二乘规则对多尺度概率模型中的参数进行估计;再后是根据贝叶斯规则对该像素处的像素值进行融合估计;最后通过利用小波包多尺度逆变换,获得目标场景基于多个传感器图像的融合估计结果.应用该算法我们对获得的可见光和红外两种传感器图像进行计算机仿真实验,结果表明,与相关的方法相比新算法更有效.
