Quality and compressibility analysis of checkerboard-based digital halftoning algorithms
… compressibility of bi-level images produced by checkerboard-based halftoning algorithms. The specific halftone methods of this study are those described by R.M. Case. The bi-level images are created using C/C++ implementations of these algorithms (Villarreal, 2001). Image quality is assessed …

DNA-DNA Checkerboard Hybridization to Identify Bacteria in Human Plaque Samples
… 15 oral bacteria. These probes were used with a checkerboard DNA-DNA hybridization scheme to analyze whether human plaque samples contained any of the 15 bacterial species. Our results have shown that this method is successful in identifying bacterial DNA present in the subgingival patient plaque …

STM studies of the nanoscale electronic landscape of the cuprates
… in electronic density due to phenomena such as checkerboard order and quasiparticle interference. This thesis presents two studies of these patterns and their implications. In the first, I present a doping and temperature dependent study of checkerboard order in the cuprate superconductor Bi2Sr …

Avaliação do sinergismo entre os componentes da pasta ctz e o citronelol frente ao enterococcus faecalis
… against Enterococcus faecalis (ATCC 29212). The checkerboard test was performed to verify the interaction between substances, through the Fractional Inhibitory Concentration Index (IFIC). For this purpose, considering the Minimum Inhibitory Concentration (MIC) as the lowest concentration capable …

Tribology and Micro-Chemistry of Sputter Deposited Composite Coatings on Honed Steel Substrates
… honed steel substrates which consisted of a checkerboard of raised squares separated by 1.5 (mu)m deep channels were prepared by photolithographic and masking techniques. A pin-on-disc apparatus was used to measure friction and wear characteristics of composite coatings. The composite coating …

Manipulating Paradigm and Attention via a Mindfulness Meditation Training Program Improves P300-Based BCI.
… A second aim is to test the efficacy of the checkerboard paradigm (CBP) against the standard row-column paradigm (RCP). Online results show that MMTP had greater accuracies than CTRL and that CBP outperformed the RCP. MMTP participants provided greater amplitude positive target responses, but …

Atividade sinérgica do citral em associação com antimicrobianos convencionais frente à Enterococcus faecalis multirresistentes
… antimicrobianos o qual foi realizado pelo método checkerboard. Os critérios utilizados para avaliar a atividade sinérgica foram definidos pelo Índice de Concentração Inibitória Fracionada (FIC index). O citral foi o mais eficaz frente as cepas de Enterococcus faecalis avaliadas quando comparado ao …

Image Compression and Channel Error Correction using Neurally-Inspired Network Models
… quality, such as PSNR and SSIM. With a regular checkerboard mask, decompressed images were superior as assessed by both subjective and pixel-wise measures. I hypothesized that alternative feature-based measures of reconstruction quality would better support my subjective observations. To test …

Majorana-based Topological Quantum Algorithms in Magnet-Superconductor Hybrid Structures
… realized in two-dimensional MSH systems using a checkerboard and spiral magnetic structures. This intriguing topological phase shows unique and edge-dependent low-energy modes, which can be used to identify the underlying topology. Moreover, I will show how the ability to manipulate the magnetic …

Use of plant-derived essential oil compounds, naturally-occurring apple aroma compounds, and apple juice flavoring mixtures to control the growth of Escherichia coli O157:H7
… The standard agar dilution method (SAD) and checkerboard assay were used to evaluate the efficacy of the nine compounds, alone and in combination against E. coli O157:H7. In general, the EO compounds were significantly more effective against E. coli O157:H7 than the AA compounds (P<0.05). …

Variational study of strongly correlated electronic models
… consistent the- ory. In particular, the issue of checkerboard spatial modulations in the density of states in the low temperature regime of the cuprates is addressed. Finally, we have studied the possibility for spontaneous orbital currents in the cuprates, that might play a key role in the theory …
