Solvent-dependent electrical characteristics and stability of organic thin-film transistors with drop cast bis(triisopropylsilylethynyl) pentacene
Applied Physics Letters, 2008Co-Authors: Chang Su Kim, Stephanie S. Lee, Enrique D. Gomez, John E. Anthony, Yueh-lin LooAbstract:The solvent from which the active layer is drop cast dramatically influences the electrical characteristics and electrical stability of thin-film transistors comprising bis(triisopropylsilylethynyl) pentacene. Casting from high boiling solvents allows slower crystallization; devices cast from toluene and chlorobenzene thus exhibit mobilities >0.1 cm2/V s and on/off ratios of ∼106. More importantly, the solvent choice influences the device stability. Devices from toluene exhibit stable characteristics, whereas devices from chlorobenzene show hystereses on cycling, with dramatic threshold voltage shifts toward positive voltages. The instability in chlorobenzene devices is attributed to the migration of water and solvent impurities to the charge Transport Interface on repetitive testing.

System and Transport Interface of SVC
IEEE Transactions on Circuits and Systems for Video Technology, 2007Co-Authors: Ye-kui Wang, Alex Eleftheriadis, Stéphane Pateux, Miska Matias Hannuksela, Stephan WengerAbstract:Scalable video coding (SVC) and transmission has been a research topic for many years. Among other objectives, it aims to support different receiving devices, perhaps connected through a heterogeneous network structure, using a single bit stream. Earlier attempts of standardized scalable video coding, for example in MPEG-2, H.263, or MPEG-4 Visual, have not been commercially successful. Nevertheless, the Joint Video Team has recently focused on the development of the scalable video extensions of H.264/AVC, known as SVC. Some of the key problems of older scalable compression techniques have been solved in SVC and, at the same time, new and compelling use cases for SVC have been identified. While it is certainly important to develop coding tools targeted at high coding efficiency, the design of the features of the Interface between the core coding technologies and the system and Transport are also of vital importance for the success of SVC. Only through this Interface, and novel mechanisms defined therein, applications can take advantage of the scalability features of the coded video signal. This paper provides an overview of the system Interface features defined in the SVC specification. We discuss, amongst other features, bit stream structure, extended network abstraction layer (NAL) unit header, and supplemental enhancement information (SEI) messages related to scalability information.

ICIP - System and Transport Interface of H.264/AVC Scalable Extension
2006 International Conference on Image Processing, 2006Co-Authors: Ye-kui Wang, Stephan Wenger, Miska HannukselaAbstract:The scalable extension of H.264/AVC, known as scalable video coding or SVC, has recently been the main focus of the Joint Video Team. The higher level syntax of SVC follows the design principles of H.264/AVC. This allows the work towards an optimized file format and RTF payload format to be conducted in parallel with the core SVC specification. This paper provides an overview of the system and Transport Interface design of SVC, including the SVC high-level syntax and functionalities, SVC file format, and SVC RTF payload format.

Aquaporin-1 in plasma membrane and caveolae provides mercury-sensitive water channels across lung endothelium
American Journal of Physiology-Heart and Circulatory Physiology, 1996Co-Authors: Jan E. SchnitzerAbstract:Classically, water Transport across endothelium of the continuous type found in the microvessels of many organs such as lung was thought to occur almost completely via the paracellular pathway through intercellular junctions. Direct transmembrane and transcellular Transport was considered to be minimal. In this study, we focused on the critical Transport Interface in direct contact with the circulating blood by purifying luminal endothelial cell plasma membranes directly from rat lungs and then isolating the noncoated plasmalemmal vesicles or caveolae from these membranes. Immunoblotting of these fractions showed that the transmembrane water channel protein aquaporin-1 was amply expressed on the endothelial cell surface at levels comparable to rat erythrocyte plasma membranes. It was found concentrated, but not exclusively, in caveolae. The functional role of these water channels in Transport was examined in rat lungs perfused in situ with tritiated water by testing known inhibitors of aquaporin-1-mediated transmembrane water Transport. Mercurial sulfhydryl reagents such as HgCl2 reversibly reduced tritiated water uptake without affecting small solute Transport. Just like certain epithelia, endothelia might express physiologically relevant amounts of aquaporin-1 on their cell surface to permit direct, mercurial-sensitive, transcellular Transport of water.
