Ink property for high-quality printed carbon nanotube (CNT) transistor was investigated and it was found that adhesion property of the semiconducting (s-) CNT micelles was a key issue. Anionic surfactants would prevent the s-CNT micelles from being adsorbed to the surface which was functionalized by amino groups and deteriorate the device characteristics. High-quality and high-uniform CNT transistors...
In the last decade, proof-number search and Monte-Carlo methods have successfully been applied to the combinatorial-games domain. Proof-number search is a reliable algorithm. It requires a well defined goal to prove. This can be seen as a disadvantage. In contrast to proof-number search, Monte-Carlo evaluation is a flexible stochastic evaluation for game-tree search. In order to improve the efficiency...
This paper presents a 4-move perfect ZKIP of knowledge with no cryptographic assumption for the random self reducible problems [TW87] whose domain is NP∩BPP. The certified discrete log problem is such an example. (Finding a witness is more difficult than the language membership problem.) A largely simplified 4-move ZKIP for the Hamilton Circuit problem is also shown. In our ZKIP, a trapdoor coin flipping...
Proof-Number Search (PNS) is a powerful method for solving games and game positions. Over the years, the research on PNS has steadily produced new insights and techniques. With multi-core processors becoming established in the recent past, the question of parallelizing PNS has gained new urgency. This article presents a new technique called Randomized Parallel Proof-Number Search (RPPNS) for parallelizing...
Recently, Monte-Carlo Tree Search (MCTS) has advanced the field of computer Go substantially. In this article we investigate the application of MCTS for the game Lines of Action (LOA). A new MCTS variant, called MCTS-Solver, has been designed to play narrow tactical lines better in sudden-death games such as LOA. The variant differs from the traditional MCTS in respect to backpropagation and selection...
Possibility of controlling the threshold voltage of printed carbon nanotube (CNT) transistor is shown. Printed CNT transistors are fabricated by mask-less printing and coating process on plastic film, and polymeric cover layer which contains phthalocyanine pigment is printed on the CNT channel. Forming the cover layer, threshold voltage shifts by 30 V to negative direction. It successfully reduces...
Printed electronics is expected to be a low-cost, eco-friendly, and on-demand fabrication technology because it decreases the number of process steps and the amount of waste materials. Carbon nanotube (CNT) transistor arrays were fabricated on plastic films by maskless printing without any additional pattering process, and minimum materials were used. During fabrication, the morphology of the CNT...
Fabrication technology for printed carbon nanotube (CNT) transistors was developed. All electrodes, insulators, and CNT channels were directly printed and CNT thin film transistors (TFTs) were fabricated on plastic films without additional patterning processes. In this fabrication, surface free energy was controlled and a mechanism for adsorbing CNTs was applied to form a random network channel. Purified...
This paper reports a design, fabrication, and experimental results of a lamination micromixer with a newly added middle partition plate for efficient mixing. The lamination mixer was simply fabricated in a silicon wafer by double side DRIE processes and combination masks of silicon dioxide and photoresist. The mixing chip contained 10 steps lamination mixer which split a solution to upper and lower...
We experimentally demonstrated wide dynamic range wavelength conversion employing simple feedback control with monitor PD and gain control SOA. Wide dynamic range of 10 dB was achieved for 43 Gbps NRZ signal.
Over the years, an increasing number of two-player games has been added to the list of solved games. However, solving multi-player games has so far received little, if any, attention. One of the reasons is that while two-player games have a unique game-theoretical value, no unique game-theoretical value may exist in multi-player games as they can have many equilibrium points. We propose solving multi-player...
