Flexible transistor active matrix array is fabricated on PEN substrate using all screen-printed gate, source and drain electrodes. Parylene-C and DNTT act as gate dielectric layer and semiconductor, respectively. The transistor possesses high mobility (0.33 cm 2 V -1 s -1 ), large on/off ratio (> 10 6 ) and low leakage current (~10 pA). Active matrix array consists of 10×10 transistors were dem...

As the communication becomes a global affair today, engineers had begin to look into the heterogeneous network solution for faster and cheaper deployment. For heterogeneous network to function properly, efficient and effective mobility management is vital to ensure uninterruptable and ubiquitous connection. Recently there has been many works done to replace the traditional handoff decision algo...

Na energy storage technology is strategically attractive for large scale applications such as grid energy storage. We show in this paper that there is a clear relation between the Jahn−Teller activity of a transition metal ion at the end of charge and the mobility of Na in a cathode material. This is particularly important as mobility at the end of charge limits the capacity of current material...

Next generation wireless networks will rely heavily on packet transport for both data and voice services. In this paper, we describe the Router for Integrated Mobile Access (RIMA) system, which is the core network element of an integrated wireless packet network. RIMA acts as a Mobile Switching Center for standard cellular telephony users, and a mobile router for wireless packet data users. RIM...

There is growing evidence that AT-rich promoter elements play a role in transcription of plant genes. For the promoter of the nuclear gene for chloroplast glutamine synthetase from pea (GS2), the deletion of a 33-bp AT-rich sequence (box 1 native) from the 5'end of a GS2 promoter-P-glucuronidase (GUS) fusion resulted in a 10-fold reduction inGUS activity. The box 1 native element was used in ge...

In this work, zinc indium tin oxide layers with different compositions are used as the active layer of thin film transistors. This multicomponent transparent conductive oxide is gaining great interest due to its reduced content of the scarce indium element. Experimental data indicate that the incorporation of zinc promotes the creation of oxygen vacancies. In thin-film transistors this effect l...

PURPOSE Agents that increase intracellular levels of cAMP mediate gene expression associated with cellular morphology, growth, and/or differentiation via the cAMP response element (CRE). The cAMP element binding protein (CREB) is a transcriptional activator that binds and stimulates gene expression from the CRE in the promoters of cAMP responsive genes. This study was designed to characterize t...

Spintronics attracts much attention because of the potential to build novel spin-based devices which are superior to nowadays charge-based microelectronic devices. Silicon, the main element of microelectronics, is promising for spin-driven applications. Understanding the details of the spin propagation in silicon structures is a key for building novel spin-based nanoelectronic devices. We inves...

There exist several examples of mobile group I introns. These introns appear to use a straightforward mechanism to achieve highly site-specific and efficient insertion into homologous intronless genes. Because the only intron-specific function required by the prevailing model for the mechanism of intron mobility is the introduction of a site-specific double-stranded break in the intronless reci...

A mesenchymal-epithelial cell interaction exists in the testis between the Sertoli cells that form the seminiferous tubule and the mesenchymal-derived peritubular myoid cells that surround the tubule. Analysis of the mesenchymal-epithelial interactions between these cells revealed the local production of a mesenchymal factor, PModS. PModS modulates the differentiated functions of Sertoli cells ...
