Zero-index materials exhibit exotic optical properties that can be utilized for integrated-optics applications. However, practical implementation requires compatibility with complementary metallic-oxide-semiconductor (CMOS) technologies. We demonstrate a CMOS-compatible zero-index metamaterial consisting of a square array of air holes in a 220-nm-thick silicon-on-insulator (SOI) wafer. This des...

A new technique for the refractive index change with high-sensitivity measurements was proposed by the digital image of porous silicon (PSi) microarray utilization in this paper. Under the irradiation of a He-Ne laser, the surface images of the PSi array cells with the microcavity structure were obtained by the digital imaging equipment, whereas the refractive index change of each array cells w...

Effective parallelization of fine-grained tasks, such as in dynamic program analysis, is challenging because thread communication overheads may outweigh the benefits of parallelism. In this paper, we address this issue with deferred methods, a novel Java framework that aggregates invocations of analysis methods in thread-local buffers and processes them altogether when a buffer is full. The fra...

Conn (1942) observed that Alcaligenes faecalis required organic nitrogen, but as observed by Porter (1946) no report was found of a study of nitrogen compounds suitable for continued growth of A. faecalis. It was reported, however, that this organism grew in a medium containing NH4 lactate as a source of nitrogen and carbon (Braun and Cahn-Bronner, 1921), and used NH4NO3, asparagine, cysteine, ...

Since the isolation and discovery of human T-cell leukemia virus type 1 (HTLV-1) over 30 years ago, researchers have utilized animal models to study HTLV-1 transmission, viral persistence, virus-elicited immune responses, and HTLV-1-associated disease development (ATL, HAM/TSP). Non-human primates, rabbits, rats, and mice have all been used to help understand HTLV-1 biology and disease progress...

The present study was designed to assess the effects of the Transcendental Meditation (TM) program on strength of the nervous system, perceptual reactance, reaction time, and auditory threshold. Three reaction time indices of strength of the nervous system were utilized: 1) Nebylitsyn's index, 2) the slope index, and 3) the low level stimulation index. Absolute auditory threshold was the fourth...

The analysis of changes in water quality in a monitoring network system is important because the sources of pollution vary in time and space. This study utilized analysis of the water quality index calculation, hierarchical cluster analysis, and mapping. This was achieved by assessing the water quality parameters of the samples collected from Galma River in Zaria, Northwestern Nigeria in wet an...
