| 3 | EAT-NAS: elastic architecture transfer for accelerating large-scale neural architecture search显示文摘Neural architecture search(NAS) methods have been proposed to relieve human experts from tedious architecture engineering. However, most current methods are constrained in small-scale search owing to the issue of huge computational resource consumption. Meanwhile, the direct application of architectures searched on small datasets to large datasets often bears no performance guarantee due to the discrepancy between different datasets. This limitation impedes the wide use of NAS on large-scale tasks. To overcome this obstacle, we propose an elastic architecture transfer mechanism for accelerating large-scale NAS(EATNAS).In our implementations, the architectures are first searched on a small dataset, e.g., CIFAR-10. The best one is chosen as the basic architecture. The search process on a large dataset, e.g., ImageNet, is initialized with the basic architecture as the seed. The large-scale search process is accelerated with the help of the basic architecture. We propose not only a NAS method but also a mechanism for architecture-level transfer learning. In our experiments, we obtain two final models EATNet-A and EATNet-B, which achieve competitive accuracies of 75.5% and 75.6%, respectively, on ImageNet. Both the models also surpass the models searched from scratch on ImageNet under the same settings. For the computational cost, EAT-NAS takes only fewer than 5 days using 8 TITAN X GPUs, which is significantly less than the computational consumption of the state-of-the-art large-scale NAS methods. | Jiemin FANG Yukang CHEN Xinbang ZHANG Qian ZHANG Chang HUANG Gaofeng MENG Wenyu LIU Xinggang WANG | 2021 | Science China(Information Sciences)2021,64,9: | 1 |

| 10 | Electrohydrodynamic 3D printing of orderly carbon/nickel composite network as supercapacitor electrodes显示文摘Electrohydrodynamic(EHD)3D printing of ca rbon-based materials in the form of orderly networks can have various applications.In this work,microscale carbon/nickel(C-Ni)composite electrodes with controlled porosity have been utilized in electrochemical energy storage of supercapacitors.Polyacrylonitrile(PAN)was chosen as the basic material for its excellent carbonization performance and EHD printing property.Nickel nitrate(Ni(NO_(3))_(2))was incorporated to form Ni nanoparticles which can improve the conductivity and the capacitance performance of the electrode.Well-aligned PAN-Ni(NO_(3))_(2) composite structures have been fabricated and carbonized as C-Ni electrodes with the typical diameter of 9.2±2.1μm.The porosity of the as-prepared C-Ni electrode can be controlled during the EHD process.Electrochemical results show the C-Ni network electrode has achieved a 2.3 times higher areal specific capacitance and 1.7 times higher mass specific capacitance than those of a spin-coated electrode.As such,this process offers a facile and scalable strategy for the fabrication of orderly carbon-based conductive structures for various applications such as energy storage devices and printable electronics. | Bing Zhang Jiankang He Gaofeng Zheng Yuanyuan Huang Chaohung Wang Peisheng He Fanping Sui Lingchao Meng Liwei Lin | 2021 | Journal of Materials Science & Technology2021,,23: | 1 |

| 12 | Synergistic effects of compound physical factor treatment on neurological outcome after peripheral nerve entrapment surgery A randomized controlled study显示文摘BACKGROUND: Iatrophysics can improve the velocity of local microcirculation at peripheral nerve injured sites and promote the recovery from injury. Research has shown that simultaneous application of two physical factors has synergistic effects on the recovery of peripheral nerve function. OBJECTIVE: To treat patients that received peripheral nerve entrapment surgery with comprehensive rehabilitation by decimeter wave therapy and electrical stimulation, and to observe the clinical effects of promoting nerve function recovery. DESIGN: Randomized controlled study. SETTINGS: Department of Orthopaedics, the Third Hospital of Baoding; Department of Hand Surgery, the Third Hospital of Hebei Medical University; Woman-Children Healthcare Center, Southern District, Baoding. PARTICIPANTS: A total of 124 patients, who received peripheral nerve entrapment surgery, were selected from the Department of Orthopaedics, the Third Hospital of Baoding between July 2001 and May 2007. All patients met the diagnostic standard of peripheral nerve entrapment syndrome defined by Doctor Chen in 1995. All subjects gave informed consent for treatments and conditions involved. The experiment was approved by a local ethics committee. All patients were randomly divided into four groups: electrical stimulation group, decimeter wave group, compound physical factor group, and control group, with 31 subjects in each group. METHODS: Patients received neurolysis at an appropriate interval after hospitalization. ① Multi-form wave therapeutic equipment made in China was used to treat patients in the electrical stimulation group after neurolysis. Wave form, stimulus width, interval time, and stimulus intensity were regulated based on the grade of nerve injury. The details were as follows: mild nerve injury: 50-100-ms stimulus width and 1 500-2 000-ms intervals; moderate nerve injury: 100-200-ms stimulus width and 3 000-4 000-ms intervals; severe nerve injury: 200-300-ms stimulus width and 3 000-6 000-ms intervals. Current dosage was 20- 40 mA. The electrical stimulation was given 6 minutes/session, once a day, and 20 days were regarded as one treatment cycle. ② A TMA-A double-frequent mild-hot therapeutic instrument was used on patients in the decimeter wave group after neurolysis. The therapeutic program was adapted to the early and middle-late phase. In the early phase, the decimeter wave was 10-15 W, 10 minutes/session, once a day; in the middle-late phase, the decimeter wave was 10-30 W, 20 minutes/session, once a day. Twenty days were regarded as one treatment cycle. ③ Patients in the compound physical factor group following neurolysis were treated the same as the decimeter wave group and electrical stimulation group, respectively. The treatment was performed once a day, and 20 days were regarded as one course. ④ Patients in the control group were not administered any physical treatment. MAIN OUTCOME MEASURES: Therapeutic efficacy was comprehensively evaluated based on motor and sensory evaluation criteria (set by Subassociation of Hand Surgery, Chinese Medical Association) at 1, 2, and 3 months after surgery, as well as changes in the electromyogram before and after operation. RESULTS: All 124 patients with peripheral nerve entrapment syndrome were included in the final analysis. One month after surgery, fineness rates in the electrical stimulation group, decimeter wave group, and compound physical factor group were not significantly different from those in the control group (P > 0.05). There was also no significant difference between the electrical stimulation group, decimeter wave group, and compound physical factor group (P > 0.05). Two months after surgery, fineness rates in the electrical stimulation group and decimeter wave group were not significantly different from the control group (P > 0.05). However, fineness rates were higher in the compound physical factor group compared to the otherthree groups (P < 0.05). There was no significant difference between the electrical stimulation group and the decimeter wave group (P > 0.05). Three months after operation, fineness rates in the electrical stimulation group, decimeter wave group, and compound physical factor group were higher than the control group (P < 0.05). However, there was no significant difference between the electrical stimulation group, decimeter wave group, and compound physical factor group (P > 0.05). CONCLUSION: The combination of decimeter wave therapy and electrical stimulation can remarkably shorten the recovery time of peripheral nerve function. The synergistic effect is superior to that of electrical stimulation and decimeter wave alone. This suggests that those two physical factors have synergistic effects on the treatment of peripheral nerve entrapment syndrome. | Gaofeng Li Dehu Tian Jianli Yu Wenzhi Li Jie Meng | 2008 | Neural Regeneration Research2008,3,1: | 0 |

| 14 | Distributed power allocation with a novel signaling in dense OFDMA small cell networks显示文摘A distributed power allocation scheme was presented to maximize the system capacity in dense small cell networks. A new signaling called inter-cell-signal to interference plus noise ratio(ISINR) as well as its modification was defined to show the algebraic properties of the system capacity. With the help of ISINR, we have an easy way to identify the local monotonicity of the system capacity. Then on each subchannel in iteration, we divide the small cell evolved node B's(Se NBs) into different subsets. For the first subset, the sum rate is convex with respect to the power domain and the power optimally was allocated. On the other hand, for the second subset, the sum rate is monotone decreasing and the Se NBs would abandon the subchannel in this iteration. The two strategies are applied iteratively to improve the system capacity. Simulations show that the proposed scheme can achieve much larger system capacity than the conventional ones. The scheme can achieve a promising tradeoff between performance and signaling overhead. | Wang Meng Tian Hui Nie Gaofeng Wang Zhibo Liu Yang | 2015 | The Journal of China Universities of Posts and Telecommunications2015,22,3: | 0 |
| 15 | Interactive information disclosure and non-penalty regulatory review risk显示文摘Using monthly data from the Shenzhen Stock Exchange's‘Hudongyi’platform and comment letters from December 2014 to December 2018,this study investigates the influence of interactive information disclosure on non-penalty regulatory review risk.The findings reveal that the richness and activeness of interactive information disclosure are positively associated with regulatory review risk.Moreover,the non-penalty regulatory review is effective as it significantly reduces the probability of receiving a comment letter in the subsequent three periods.The timeliness of interactive information disclosure is negatively associated with regulatory review risks.Additionally,we find that newspaper media coverage partially mediates the relationship between interactive information disclosure and regulatory review risk.For companies with low levels of internal governance,in low-competitive industries,and state-owned companies,the positive relationship between the number of investor questions and regulatory review risk is strengthened.These findings enrich the literature on the determinants of regulatory review risk and the economic consequences of interactive information disclosure in emerging markets. | Meng Wang Yongjie Zhang Yizhe Dong Gaofeng Zou Wanlong Zhao | 2023 | Journal of Management Science and Engineering2023,8,1: | 0 |
| 16 | High-performance computing of 3D blasting wave propagation in underground rock cavern by using 4D-LSM on TianHe-3 prototype E class supercomputer显示文摘Parallel computing assigns the computing model to different processors on different devices and implements it simultaneously.Accordingly,it has broad applications in the numerical simulation of geotechnical engineering and underground engineering,of which models are always large-scale.With parallel computing,the computing time or the memory requirements will be reduced by splitting the original domain of the numerical model into many subdomains,which is thus named as the domain decomposition method.In this study,a cubic and equal volume domain decomposition strategy was utilized to realize the parallel computing on the distributed memory system of four-dimensional lattice spring model(4D-LSM)based on the message passing interface.With a more efficient communication strategy introduced,this study aimed at operating an one-billion-particle model on a supercomputer platform.The preprocessing procedure of the parallelized 4D-LSM was restructured and the particle generation strategy suitable for the supercomputer platform was employed to minimize the time consumption in preprocessing and calculation.On this basis,numerical calculations were performed on TianHe-3 prototype E class supercomputer at the National Supercomputer Center in Tianjin.Two fieldscale three-dimensional blasting wave propagation models were carried out,of which the numerical results verify the computing power and the advantage of the parallelized 4D-LSM in the simulation of large-scale three-dimension models.Subsequently,the time complexity and spatial complexity of 4D-LSM and other particle discrete element methods were analyzed. | Meng Fu Gaofeng Zhao | 2022 | Deep Underground Science and Engineering2022,1,1: | 0 |
