| 1 | Semi-Supervised Learning with Generative Adversarial Networks on Digital Signal Modulation Classification显示文摘Deep Learning(DL)is such a powerful tool that we have seen tremendous success in areas such as Computer Vision,Speech Recognition,and Natural Language Processing.Since Automated Modulation Classification(AMC)is an important part in Cognitive Radio Networks,we try to explore its potential in solving signal modulation recognition problem.It cannot be overlooked that DL model is a complex model,thus making them prone to over-fitting.DL model requires many training data to combat with over-fitting,but adding high quality labels to training data manually is not always cheap and accessible,especially in real-time system,which may counter unprecedented data in dataset.Semi-supervised Learning is a way to exploit unlabeled data effectively to reduce over-fitting in DL.In this paper,we extend Generative Adversarial Networks(GANs)to the semi-supervised learning will show it is a method can be used to create a more dataefficient classifier. | Ya Tu Yun Lin Jin Wang Jeong-Uk Kim | 2018 | Computers, Materials & Continua2018，，5： | 28 |
| 2 | Effect of electroacupuncture on glial fibrillary acidic protein and nerve growth factor in the hippocampus of rats with hyperlipidemia and middle cerebral artery thrombus显示文摘Electroacupuncture(EA)has been shown to reduce blood lipid level and improve cerebral ischemia in rats with hyperlipemia complicated by cerebral ischemia.However,there are few studies on the results and mechanism of the effect of EA in reducing blood lipid level or promoting neural repair after stroke in hyperlipidemic subjects.In this study,EA was applied to a rat model of hyperlipidemia and middle cerebral artery thrombosis and the condition of neurons and astrocytes after hippocampal injury was assessed.Except for the normal group,rats in other groups were fed a high-fat diet throughout the whole experiment.Hyperlipidemia models were established in rats fed a high-fat diet for 6 weeks.Middle cerebral artery thrombus models were induced by pasting 50%FeCl3 filter paper on the left middle cerebral artery for 20 minutes on day 50 as the model group.EA1 group rats received EA at bilateral ST40(Fenglong)for 7 days before the thrombosis.Rats in the EA1 and EA2 groups received EA at GV20(Baihui)and bilateral ST40 for 14 days after model establishment.Neuronal health was assessed by hematoxylin-eosin staining in the brain.Hyperlipidemia was assessed by biochemical methods that measured total cholesterol,triglyceride,low-density lipoprotein and high-density lipoprotein in blood sera.Behavioral analysis was used to confirm the establishment of the model.Immunohistochemical methods were used to detect the expression of glial fibrillary acidic protein and nerve growth factor in the hippocampal CA1 region.The results demonstrated that,compared with the model group,blood lipid levels significantly decreased,glial fibrillary acidic protein immunoreactivity was significantly weakened and nerve growth factor immunoreactivity was significantly enhanced in the EA1 and EA2 groups.The repair effect was superior in the EA1 group than in the EA2 group.These findings confirm that EA can reduce blood lipid,inhibit glial fibrillary acidic protein expression and promote nerve growth factor expression in the hippocampal CA1 region after hyperlipidemia and middle cerebral artery thrombosis.All experimental procedures and protocols were approved by the Animal Use and Management Committee of Beijing University of Chinese Medicine,China(approval No.BUCM-3-2018022802-1002)on April 12,2018. | Na-Ying Xue Dong-Yu Ge Rui-Juan Dong Hyung-Hwan Kim Xiu-Jun Ren Ya Tu | 2021 | Neural Regeneration Research2021，16，1： | 9 |
| 3 | Influence of Acupuncture on Autonomic Balance in Adult Tinnitus Patients:An Exploratory Study显示文摘Acupuncture is an alternative therapy for tinnitus in clinical practice.The mechanism by which acupuncture can alleviate tinnitus is still unknown.Autonomic nervous system was reported to be responsible for tinnitus.The aim of this study was to explore the effect of acupuncture on autonomic balance in adult tinnitus patients.Thirty patients were randomly assigned into either the deep acupuncture(DA)group or the shallow acupuncture(SA)group.Each patient received 6 acupuncture sessions(a-f phase)over three weeks.Measures of heart rate variability and Tinnitus Handicap Inventory(THI)were obtained at baseline and after the sixth acupuncture session in all patients.The results showed that the low frequency/high frequency(LF/HF)pattern was increased at b-f phase until the sixth acupuncture session when compared with that at the first acupuncture session in DA group.However,it continuously increased at b-f phase in SA group even at the sixth acupuncture session,which was not significantly different from that at the first acupuncture session.The decrease in THI in DA group was greater than that in SA group after 3-week treatment(P=0.043).Our preliminary study suggests three-week deep acupuncture can improve tinnitus symptoms in adult tinnitus patients,which may be related to the regulation of autonomic nervous system balance. | Jian-feng TU Mirim Kim Jing-wen YANG Qian-qian LI Gerhard Litscher Lu WANG Guang-xia SHI Daniela Litscher Cun-zhi LIU | 2019 | Current Medical Science2019，39，6： | 2 |
| 4 | Upconversion luminescence of Gd2O3:Er3+and Gd2O3:Er3+/silica nanophosphors fabricated by EDTA combustion method显示文摘Gd2O3:Er^3+nanophosphors were fabricated by the combustion method in presence of Na2 ethylene diamine tetra acetic acid(EDTA-Na2)as fuel at not high temperature(≤350℃)within a very short time of 5 min.The added concentration of Er^3+ions in Gd2O3 matrix was changed from 0.5 mol%to 5.0 mol%.The X-ray diffraction pattern of samples indicates the monoclinic structure of Gd2O3:Er^3+.The morphology and chemical composition analysis of the Gd2O3:Er^3+samples are characterized by a field emission scanning electron microscope(FESEM)and a Fourier-transform infrared spectrometer(FTIR).The photoluminescence(PL),photo luminescence excitation(PLE)and upconversion(UC)at room temperature of the prepared materials with different concentrations of Er^3+were investigated.The PL of Gd2O3:Er^3+nanomaterials are shown in visible at 545,594,623,648,688 nm under excitation at 275 nm.The emission bands from transitions of Er^3+from 2P3/2 to 4F9/2 are observed,UC luminescent spectra of the Gd2O3:Er^3+/silica nanocomposites under 976 nm excitation show the bands at 548 and 670 nm.The influence of excitation power at 980 nm for transitions were measured and calculated.The results indicate that the upconversion process of Gd2O3:Er^3+/silica is two photons absorption mechanism.The low temperature dependence of UC luminescent intensities of the main bands of Gd2O3:Er^3+was investigated towards development of a nanotemperature sensor in the range of 10-300 K. | Le Quoc Minh Tran Kim Anh Nguyen Duy Hung Pham Thi Minh Chau Nguyen Thi Quy Hai Ho Van Tuyen Vu Thi Thai Ha Vu Duc Tu Wieslaw Strek | 2019 | Journal of Rare Earths2019，37，11： | 2 |
