The log-periodic dipole array (LPDA) has become the most popular commercial antenna for reception of TV signal in VHF and UHF bands in Europe. The antenna consists of two booms of a square cross section to which dipoles are attached (Figure 1). The booms play the role of the feeding two-conductor line. The dimensions of the boom are relatively large compared to the wavelength and the dipole len...

Effect of the specific gene knockout on the main metabolism in Escherichia coli was reviewed, and the regulation mechanisms were clarified based on different levels of information such as gene expressions, enzyme activities, intracellular metabolite concentrations, and metabolic fluxes together with fermentation data. The effects of the knockout of such genes as pflA, pta, ppc, pykF, adhE, and ...

Ohr, a bacterial protein encoded by the Organic Hydroperoxide Resistance (ohr) gene, plays a critical role in resistance to organic hydroperoxides. In the present study, we show that the Cys-based thiol-dependent Ohr of Corynebacterium glutamicum decomposes organic hydroperoxides more efficiently than hydrogen peroxide. Replacement of either of the two Cys residues of Ohr by a Ser residue resul...

In this work, a system able to monitor the crowd density detecting mobile phone communications through analysis of electromagnetic spectrum is proposed and experimentally assessed. The variations are collected with low-cost analyzer, high gain log-periodic directive antenna (LPDA). objective relate spectral power in given frequency band estimate connections present number people area. particula...

In this work, a 3D capacitive coupling structure employing periodic pattern was used for application to miniaturized on-chip passive components on MMIC (Monolithic Microwave Integrated Circuit). Unlike conventional periodic structure, the characteristic impedance of the 3D capacitive coupling structure was hardly dependent on frequency. Using the 3D capacitive coupling structure, RF passive com...

The objective of this study was to assess the feasibility and reliability of using miniaturized disk dissolution apparatus for intrinsic dissolution rate (IDR) measurement in the early drug discovery process when bulk drug supply is very limited. The two apparatus, a miniaturized rotating disk system (mRDS) and a miniaturized stationary disk system (mSDS), were evaluated using chloramphenicol a...

Abstract Near-field (NF) signal distribution behavior with a radius of 150 meters was studied to compare far-field (FF) characteristics. It can be found more flexible and detailed in NF than the from an monitor only single location. The origin measured value detection method on equipment introduced detail. three-dimensional model established optimized by phase analysis as well data on-site. The...

We demonstrate a novel approach for building situated information systems using wirelessly connected miniaturized displays. These displays are spatially distributed in a physical work environment and present situated glyphs human-readable abstract graphical signs to provide activity centric notification and feedback. The demo will showcase how such miniaturized display networks can be used in d...
