This paper presents the status of land-surface temperature (LST) standard products retrieved from Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) data. Based on estimates of the channel-dependence error and noise equivalent temperature difference (NEDT) and the calibration accuracy of MODIS thermal–infrared data, the(More)
This paper presents the outer-round only pipelined architecture for a FPGA implementation of the AES-128 encryption processor. The proposed design uses the Block RAM storing the S-box values and exploits two kinds of Block RAM. By combining the operations in a single round, we can reduce the critical delay. Therefore, our design can achieve a throughput of(More)
Oxidative stress has been suggested to play a key role in the neuropathogenesis of HIV infection. HIV proteins (gp120, Tat) and proinflammatory cytokines can trigger the production of reactive oxygen species (ROS), resulting in DNA and RNA lesions. Among all the lesions induced by ROS, one of the most abundant lesions in DNA and RNA is(More)
Although combined antiretroviral therapy has significantly improved the prognosis of HIV-1 infected patients and decreased the incidence of HIV-1 associated dementia, the cumulative prevalence of this disease, in particular, mild or asymptomatic neurocognitive impairment, has not decreased. Thus, in addition to active antiretroviral therapy, the search for(More)
Nucleoside analogue reverse transcriptase inhibitor (NRTI), an integral component of highly active antiretroviral therapy (HAART), was widely used to inhibit HIV replication. Long-term exposure to NRTIs can result in mitochondrial toxicity which manifests as lipoatrophy, lactic acidosis, cardiomyopathy and myopathy, as well as polyneuropathy. But the(More)
The polymorphisms of the tumor suppressor gene p53 have been extensively investigated in numerous malignant tumors, particularly carcinomas associated with human papillomavirus (HPV) infection. However, the results remain controversial. To address a potential correlation between the p53 genotypes and the risk of esophageal squamous cell carcinoma (ESCC), we(More)
A fast and sensitive liquid chromatography-mass spectrometry method was developed for the determination of ursolic acid (UA) in rat plasma and tissues. Glycyrrhetinic acid was used as the internal standard (IS). Chromatographic separation was performed on a 3.5 μm Zorbax SB-C18 column (30 mm × 2.1 mm) with a mobile phase consisting of methanol and aqueous(More)
We consider a single-machine scheduling problem with periodic maintenance activities. Although the scheduling problem with maintenance has attracted researchers’ attention, most of past studies considered only one maintenance period. In this research several maintenance periods are considered where each maintenance activity is scheduled after a periodic(More)
HIV-associated neurocognitive disorders (HAND), characterized by cognitive, motor, and behavioral abnormalities, are common among people living with HIV and AIDS. In combined antiretroviral therapy era in Western countries, nearly 40% of HIV-infected patients continue to suffer from HAND, mainly with mild or asymptomatic cognitive impairment. However, the(More)
