Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition applications. In this paper, we propose a novel filter design method for fingerprint image enhancement, primarily inspired from the traditional Gabor filter (TGF). The previous fingerprint image enhancement methods based on TGF banks have some drawbacks in their(More)
A unified model is proposed to elucidate the resistive switching behavior of metal-oxide-based resistive random access memory devices using the concept of electron hopping transport along filamentary conducting paths in dielectric layer. The transport calculation shows that a low-electron-occupied region along the conductive filament (CF) is formed when a(More)
MicroRNAs (miRNAs) are a class of 21–24 nucleotide non-coding RNAs that down-regulate gene expression by cleaving or inhibiting the translation of target gene transcripts. miRNAs have been extensively analyzed in a few model plant species such as Arabidopsis, rice and Populus, and partially investigated in other non-model plant species. However, only a few(More)
BACKGROUND Human leukocyte antigen DP (HLA-DP) locus has been reported to be associated with hepatitis B virus (HBV) infection in populations of Japan and Thailand. We aimed to examine whether the association can be replicated in Han Chinese populations. METHODOLOGY/PRINCIPAL FINDINGS Two HLA-DP variants rs2395309 and rs9277535 (the most strongly(More)
Phosphorous (P) deficiency is a major restraint factor for crop production and plants have developed several mechanisms to adapt to low P stress. In this study, a set of 271 introgression lines (ILs) were used to characterize the responses of seedlings to low P availability and to identify QTLs for root traits, biomass, and plant height under P-deficiency(More)
Plants have evolved and adapted to different environments. Dwarfism is an adaptive trait of plants that helps them avoid high-energy costs under unfavourable conditions. The role of gibberellin (GA) in plant development has been well established. Several plant dehydration-responsive element-binding proteins (DREBs) have been identified and reported to be(More)
In the current era of highly active antiretroviral therapy (HAART), the incidence of HIV dementia has declined, but the prevalence of HIV-associated neurocognitive disorder (HAND) remains high. HIV-induced systemic and localized inflammation is considered to be one of the mechanisms of HAND. Changes in cytokine levels in the cerebrospinal fluid (CSF) during(More)
Cellulose represents the most abundant biopolymer in nature and has great economic importance. Cellulose chains pack laterally into crystalline forms, stacking into a complicated crystallographic structure. However, the mechanism of cellulose crystallization is poorly understood. Here, via functional characterization, we report that Brittle Culm1 (BC1), a(More)
