| 1 | Deep Imitation Learning for Autonomous Vehicles Based on Convolutional Neural Networks显示文摘Providing autonomous systems with an effective quantity and quality of information from a desired task is challenging. In particular, autonomous vehicles, must have a reliable vision of their workspace to robustly accomplish driving functions. Speaking of machine vision, deep learning techniques, and specifically convolutional neural networks, have been proven to be the state of the art technology in the field. As these networks typically involve millions of parameters and elements, designing an optimal architecture for deep learning structures is a difficult task which is globally under investigation by researchers. This study experimentally evaluates the impact of three major architectural properties of convolutional networks, including the number of layers, filters, and filter size on their performance. In this study, several models with different properties are developed,equally trained, and then applied to an autonomous car in a realistic simulation environment. A new ensemble approach is also proposed to calculate and update weights for the models regarding their mean squared error values. Based on design properties,performance results are reported and compared for further investigations. Surprisingly, the number of filters itself does not largely affect the performance efficiency. As a result, proper allocation of filters with different kernel sizes through the layers introduces a considerable improvement in the performance.Achievements of this study will provide the researchers with a clear clue and direction in designing optimal network architectures for deep learning purposes. | Parham M.Kebria Abbas Khosravi Syed Moshfeq Salaken Saeid Nahavandi | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，1： | 6 |
| 2 | Intrahepatic distribution of hepatitis B virus antigens in patients with and without hepatocellular carcinoma显示文摘AIM: To study the intrahepatic expression of hepatitis B surface antigen(HBs Ag) and hepatitis B core antigen(HBc Ag) in chronic hepatitis B patients with and without hepatocellular carcinoma. METHODS: A total of 33 chronic hepatitis B patients(mean age of 40.3 ± 2.5 years), comprising of 14 HBe Ag positive and 19 HBe Ag negative patients; and 13 patients with hepatitis B virus related hepatocellular carcinoma(mean age of 49.6 ± 4.7 years), were included in our study. Immunohistochemical staining for HBc Ag and HBs Ag was done using standard streptavidin-biotin-immunoperoxidase technique on paraffin-embedded liver biopsies. The HBc Agand HBs Ag staining distributions and patterns were described according to a modified classification system. RESULTS: Compared to the HBe Ag negative patients, the HBe Ag positive patients were younger, had higher mean HBV DNA and alanine transaminases levels. All the HBe Ag positive patients had intrahepatic HBc Ag staining; predominantly with 'diffuse' distribution(79%) and 'mixed cytoplasmic/nuclear ' pattern(79%). In comparison, only 5% of the HBe Ag-negative patients had intrahepatic HBc Ag staining. However, the intrahepatic HBs Ag staining has wider distribution among the HBe Ag negative patients, namely; majority of the HBe Ag negative cases had 'patchy' HBs Ag distribution compared to 'rare' distribution among the HBe Ag positive cases. All but one patient with HCC were HBe Ag negative with either undetectable HBV DNA or very low level of viremia. Intrahepatic HBc Ag and HBs Ag were seen in 13(100%) and 10(77%) of the HCC patients respectively. Interestingly, among the 9 HCC patients on anti-viral therapy with suppressed HBV DNA, HBc Ag and HBs Ag were detected in tumor tissues but not the adjacent liver in 4(44%) and 1(11%) patient respectively. CONCLUSION: Isolated intrahepatic HBc Ag and HBs Ag can be present in tumors of patients with suppressed HBV DNA on antiviral therapy; that may predispose them to cancer development. | Parham Safaie Mugilan Poongkunran Ping-Ping Kuang Asad Javaid Carl Jacobs Rebecca Pohlmann Imad Nasser Daryl TY Lau | 2016 | World Journal of Gastroenterology2016，22，12： | 5 |
| 3 | Thermodynamic study and methanothermal temperature-programmed reaction synthesis of molybdenum carbide显示文摘Nanostructured molybdenum carbide(Mo_2C) was successfully prepared from molybdenum trioxide(MoO _3) using methanothermal temperature-programmed reaction. Thermodynamic analysis indicated that in presence of methane, the formation of Mo_2 C from MoO _3 occurs through the path of MoO _3 → MoO _2 → Mo_2 C. The carburized MoO _3 was characterized using X-ray diffraction(XRD), CHNS/O analysis, Brunauer–Emmett–Teller(BET) analysis, and field-emission scanning electron microscopy(FESEM). At final carburization temperatures of 700 and 800°C and at methane contents ranging from 5vol% to 20vol%, Mo_2 C was the only solid product observed in the XRD patterns. The results indicated that the effect of methane content on the formation of the carbide phase is substantial compared with the effect of carburization time. Elemental analysis showed that at a final temperature of 700°C, the carbon content of carburized MoO _3 is very close to the theoretical carbon mass percentage in Mo_2 C. At higher carburization temperatures, excess carbon was deposited onto the surface of Mo_2 C. High-surface-area Mo_2 C was obtained at extremely low heating rates; this high-surface-area material is a potential electrocatalyst. | Parham Roohi Reza Alizadeh Esmaeil Fatehifar | 2016 | International Journal of Minerals,Metallurgy and Materials2016，23，3： | 4 |

| 8 | Captive Breeding of the Four-eyed Turtle(Sacalia quadriocellata)显示文摘In 1998,a study on forty-five four-eyed turtles(Sacalia quadriocellata) was initiated to gather preliminary biological data of this species and to investigate the feasibility of its captive reproduction.In the following six years,no courtship behavior was found occurring in males and no oviposition in females.From 2004 to 2007,two successful techniques were applied to initiate reproductive behavior:1) injecting exogenous reproductive hormones;and 2) reducing the stress of living in captivity.As a result of the hormone treatments,courtship behavior and copulation were observed during September and October,2005.However,no courtship displays were seen from the CK males,which were not treated with hormones.Ovulation occurred between December and March,and the correlation was not significant between behavior of ovulation and food intake.Females laid only one clutch of eggs each year,with 2.47 eggs(n=34,range=1–4) at average,and 84 eggs were totally obtained,of which 13 were damaged,52 were infertile and 19 fertile.Of the fertile eggs,nine were hatched with mean incubation period of 105.9 days(n=9,range=89–122 days) at temperature ranging from 24 to 27℃. | HE Bin LIU Yuxiang SHI Haitao ZHANG Jie HU Maogui MA Yonggang FU Lirong HONG Meiling WANG Jichao Fong J.Jonathan Parham F.James | 2010 | Asian Herpetological Research2010，1，2： | 2 |
