Quantitative Assessment of Coumarin-Containing Polymer Film's Capability for Photoalignment of Liquid Crystals

The photoalignment of a nematic fluid, E-7, and a glassy-nematic oligofluorene, F(MB)5, was investigated on films of Polymers 1 and 2 in the parallel regime. Polarized absorption spectroscopy and computational chemistry were employed to characterize coumarin monomer's and dimer's molar extinction coefficients and to locate absorption dipoles as parallel to their long molecular axes. Moreover, their orientational order parameters, Sm and Sd, were experimentally determined as functions of the extent of dimerization. Higher Sd and Yd, coumarin dimer's mole fraction, were achieved in films of Polymer 1 than in Polymer 2 because of the greater coumarin mobility of the former. The ability of a coumarin-containing photoalignment film to orient a spin-cast F(MB)5 film was found to improve with increasing YdSd to an extent comparable to that of a rubbed polyimide film. Because of the relatively short lengths of its constituent molecules, E-7 was oriented equally well on both polymer films regardless of the YdSd va...
Silicon speedpath measurement and feedback into EDA flows

Timing, test, reliability, and noise are modeled and abstracted in our design and verification flows. Specific EDA algorithms are then designed to work with these abstracted models, often in isolation of other effects. However, tighter design margins and higher reliability issues have increased the need for accurate models and algorithms. We propose utilizing silicon data to tune and improve the EDA tools and flows. In this paper we describe a silicon methodology to isolate silicon speedpath environments and feed these into a simulation framework to temporally and spatially isolate specific speedpaths in order to model and understand the real effects. This is done using accurate electrical speedpath modeling techniques which may be used to tune the accuracy and correlation of the design models. The effort required to distinguish the many different electrical effects will be outlined.
Drag reduction by leaf aquaplaning in Hexastylis (Aristolochiaceae) and other plant species in floods

AbstractLeaves of a forest-floor plant, Hexastylisarifolia, were subjected to rapid water movement at shallow depths to approximate sheet-flow conditions during flooding. When held 20 mm below the water surface, leaves curled into cones that had higher drag. Both measured and extrapolated drag of aquaplaning and submerged leaves were well below petiole breaking strength. Leaves of some other herbaceous plants that might occasionally be exposed to sheet flow behaved similarly; most had blades with upwardly curved basal lobes and fairly long petioles. Tree leaves with similar basal lobes and long petioles did not aquaplane. The biological significance of low drag during aquaplaning remains uncertain because petiole strength and root strength should be enough to hold the plant in place during sheet flow even witho...
Leadership games and their application in super-peer networks

This paper considers a setting where a single "leadership agent" intervenes in a multi-agent system through actions that (perhaps subtly) change the dynamics of the system. We describe a number of forms this intervention can take and compare these situations to settings in previous work. We identify two important effects of leadership: faster system convergence, and convergence to a better equilibrium. Empirically, we first explore these properties in leadership of algorithms engaged in classical 2-player games. We then apply this general framework to the leadership of a super-peer file-sharing network. In these experiments the network contains some agents that make locally greedy decisions that hamper the network as a whole.We show that a leader acting based on a more global criteria can push the system to a better equilibrium point as well as speeding up convergence. We also show how a mathematical approximation of such super-peer networks can be used to aid a leader in determining a minimum-cost intervention strategy.
Improved Iterative Decoding Algorithm for Turbo Codes

This chapter primarily studies the MAP and the SOVA, and discusses the suitability of combining both algorithms. An iterative decoding algorithm is improved. The frames are first applied with SOVA iterations with error detection for iteration termination. After a fixed maximum number of SOVA iterations, the erroneous frames are continued with Log-MAP iterations. The extrinsic soft output from the last SOVA iteration are selectively fed to the first Log-MAP iteration as initial priori input. The result of the simulation shows that the improved algorithm could reduce the complexity and keep high performance.
Geometry of Quasi-Metric Spaces

The main goal of this chapter is to set the stage for the rest of this monograph by presenting a brief survey of some of the many facets of the theory of quasi-metric spaces. Quasi-metric spaces constitute generalizations of not only the classical Euclidean setting, but of quasi-Banach spaces and ultrametric spaces. In this work, quasi-metric spaces will constitute the natural geometric context in which our main results are going to be developed.
The Rhyme Book Culture of Pre-Tang China

Due to theTang’s and later imperial courts’ enforcement, yunshu 韻書(rhyme books) such as Qieyun 切韻(Spelling Rhymes), Yunlue 韻略(Concise Rhymes), and Hongwu zhengyun 洪武正韻(Standard Rhymes of the Hongwu Reign Period) came to exert extensive linguistic and cultural influence. However, during their inception before the Tang, rhyme books did not enjoy broad recognition, belonging more or less within circles of experts. In examining the case of Lu Fayan’s 陸法言(fl. 581–601) Qieyun (Spelling Rhymes; compiled ca. 601), which is often characterized as the incipient guan yun 官韻(official rhyme book) in Chinese history, the author argues for its more private and personal nature and brings to light a different picture of pre-Tang “tonal and rhyming” culture.
Alkynyl Phosphonate DNA: A Versatile “Click”able Backbone for DNA-Based Biological Applications

Major hurdles associated with DNA-based biological applications include, among others, targeted cell delivery, undesirable nonspecific effects, toxicity associated with various analogues or the reagents used to deliver oligonucleotides to cells, and stability toward intracellular enzymes. Although a plethora of diverse analogues have been investigated, a versatile methodology that can systematically address these challenges has not been developed. In this contribution, we present a new, Clickable, and versatile chemistry that can be used to rapidly introduce diverse functionality for studying these various problems. As a demonstration of the approach, we synthesized the core analogue, which is useful for introducing additional functionality, the triazolylphosphonate, and present preliminary data on its biological properties. We have developed a new phosphoramidite synthon—the alkynyl phosphinoamidite, which is compatible with conventional solid-phase oligonucleotide synthesis. Postsynthesis, the alkynylph...
