Mott-Schottky analysis was used to study the semi-conductive properties of the surface oxide. The results of the capacitance measurements showed that the oxide films on both the coating and the cast alloy were p-type semiconducting characteristics. Both the carrier density （Na）and the flat band potential （Efb） were obviously frequency-dependent, and the optimal frequency range was from 1000 to 1500 Hz. The oxidized coating exhibited higher protectivity than the oxidized cast alloy due to the lower carrier density compared with that of the oxidized cast alloy. The EIS data of the long-term immersing tests suggested that the oxide film served as an inner-barrier layer against chloride ions. The penetration of the aggressive ions into the surface oxide resulted in the decreased polarization resistance as a function of the immersion time.展开更多

For this purpose, groups of eight ferrets （6 to 7 months old） were injected with 0.5 mL of vaccine specimens containing 3.75, 7.5 or 15.0 μg of virus hemagglutinin. Administration was intramuscular and given either as a single dose or as two doses 14 days apart. All vaccine specimens manifested immunogenicity in ferrets for single （HI titer, from 51 ± 7 to 160 ± 23） and double （HI titer, from 697± 120 to 829 ± 117） administrations. To assess the protective effects of the vaccine, ferrets from the vaccinated and control groups were infected intranasally with pandemic virus A/California/7/09 （H1N1） pdm09 at a dose of 106 106/0.5 mL. Fourteen days post-infection, the ferrets inoculated with single or double vaccines containing 3.75, 7.5 or 15.0 ~g of hemagglutinin per dose showed no signs of influenza infection, weight loss, or body temperature rise, and no premature deaths occurred. The number of vaccinated ferrets shedding the virus via the upper airway, as well as the amount of virus shed after infection, was significantly reduced in comparison with animals from the control group. Based on our results, we suggest that a single vaccination at a dose of 3.75 or 7.5 μg hemagglutinin be used for Phase I clinical trials.展开更多

To building up such a system, we must follow certain working procedures which usually consist of four steps： to determine the performance objectives, to design the structure of indicator system, to specify the indicators and to set up the weight of indicators. Each step plays a different role in performance evaluation indicator system and has its own impact on the realization of performance evaluation objectives respectively. So the scientifically building up a performance evaluation indicator system is the key to determine whether the intellectual property is protected well or not.展开更多

It has a wide application in security such as FPGA intellectual property （IP） protection, key generation and digital rights management. Ring oscillator （RO） PUF and Arbiter PUF are the most popular PUFs, but they are not specially designed for FPGA. RO PUF incurs high resource overhead while obtaining less challenge-response pairs, and requires ＂hard macros＂ to implement on FPGAs. The arbiter PUF brings low resource overhead, but its structure has big bias when it is mapped on FPGAs. Anderson PUF can address these weaknesses of current Arbiter and RO PUFs implemented on FPGAs. However, it cannot be directly implemented on the new generation 28 nm FPGAs. In order to address these problems, this paper designs and implements a delay-based PUF that uses two LUTs in an SLICEM to implement two 16-bit shift registers of the PUF, 2-to-1 multiplexers in the carry chain to implement the multiplexers of the PUF, and any one of the 8 flip-flops to latch 1-bit PUF signatures. The proposed delay-based PUF is completely realized on 28 nm commercial FPGAs, and the experimental results show its high uniqueness, reliability and reconfigurability. Moreover, we test the impact of aging on it, and the results show that the effect of aging on the proposed PUF is insignificant, with only 6% bit-flips. Finally, the prospects of the proposed PUF in the FPGA binding and volatile key generation are discussed.展开更多
