Dual-band Branch Line Coupler with High Isolation Isolation Using Loaded Coupled Lines
2018 International Applied Computational Electromagnetics Society Symposium - China (ACES), 2018A novel dual-band branch line coupler with high power division isolation using coupled lines is proposed. A conventional coupler loaded with quarter-wavelength open coupled lines is adopted to realize the dual bands. Each band has a high isolation due to the introduced transmission zeros.

Isolation and characterization of an avian myogenic cell line
Developmental Biology, 1991Myogenic cell lines have proven extremely valuable for studying myogenesis in vitro. Although a number of mammalian muscle cell lines have been isolated, attempts to produce cell lines from other classes of animals have met with only limited success. We report here the isolation and characterization of seven avian myogenic cell lines (QM1-4 and QM6-8),

Fiber-embedded in-line isolator
Journal of Lightwave Technology, 1991A fiber-embedded optical isolator with a low forward loss has been developed. The isolator consists of thermally diffused expanded core fibers, laminated polarizers, and a Faraday rotation garnet. Backward and forward losses at 1.3 mu m wavelength are 44.0 and 0.9 dB, respectively. The isolator has a minute size, and its alignment is simple. >

The isolation of an antimycin A-resistant human cell line
Experimental Cell Research, 1983An antimycin A-resistant derivative of the human cell line, D98, has been obtained by selective mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine. The derivative, designed MA65, is capable of continuous growth in 15 microM antimycin and the resistant phenotype is stable in the absence of selection.

A great deal of EMI comes from electromagnetic pollution of the AC power mains (11, 12). Among the more predominant sources of contamination of primary power are: common-mode noise due to radiated pickup, differential-mode noise due to other users on the same distribution line, dropouts, and interrupts.

Isolation and Culture of Squamous Cell Carcinoma Lines
2011Cutaneous squamous cell carcinoma (SCC) keratinocytes readily grow, expand in culture, and continuously passage, suggesting either spontaneous immortalisation at the early stage of culture or inherent proliferative capacity. One feature of SCC keratinocytes is genomic DNA rearrangement and single-nucleotide polymorphism studies of fresh frozen primary ...

On-line recognition of handwritten isolated arabic characters
Pattern Recognition, 1989Abstract This paper is concerned with the recognition of isolated handwritten Arabic characters drawn on a graphic tablet. At first, features that are suitable for recognition are proposed. Features that are found to be independent of the writer style are represented as a list (vector) of integer values, while those that are subjected to more ...

Isolation and characterisation of a bipotential haematopoietic cell line
Nature, 1979VARIOUS cell lines have been used to study the regulation of proliferation and differentiation, and events occurring during mutagenesis and carcinogenesis. These include ‘normal’ cell lines which, however, frequently show chromosome changes, especially aneuploidy, and where normality is based essentially on the nontumorigenic capacity of the cells ...

Isolated power and line isolation monitors.
Biomedical instrumentation & technology, 1990Isolated power and line isolation monitor systems are standards in operating rooms and cardiac catheterization suites. They provide the patient and the equipment user with the knowledge of potential hazards. When a potential hazard occurs, appropriate corrective action can take place to prevent unnecessary injury.
