A suitable behavior is autonomously acquired by using this system. Robots learn the suitable behavior by iterating action and receiving the evaluated value of that action. The evaluated value is calculated by reward function. In general reinforcement learning, we acquire a suitable behavior by setting the suitable reward function for each problem. However in previous research of reinforcement learning, most reward functions are constructed based on human's heuristics. To construct reward functions, trial-and-error is needed, and it imposes an enormous drain on humans. Therefore we propose an approach, which automatically generate reward functions, using Genetic Programming. In this approach, we create a method evaluating reward functions. Reward functions are generated by Genetic Programming, and are evaluated by evaluating method. A suitable reward function is generated by evolution of these reward functions. In this paper, we conducted an experiment to confirm the effectiveness of proposed method. In the experiment, we generate a suitable reward function of a problem, which a route searching problem in a tile-world. Through the experiment, we confirm that the proposed approach can generate a suitable reward function, and the generated reward function can acquire a more suitable behavior in comparison with a reward function by constructed based on human's heuristics.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123380722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using cell-sized (giant) unilamellar lipid vesicles, we studied the effect of exposing the lipid vesicles to an oxidative stress environment. We found that the vesicles underwent fluctuations, and some had morphological transformation. We characterized the main products of cholesterol oxidation as 7β-hydroxycholesterol (7β) and 7-ketocholesterol (7keto). After, we prepared lipid membrane containing the above oxy-cholesterols and investigated the influence of temperature on membrane dynamics. We found that (i) 7b and 7keto rendered vesicles more responsive to temperature changes, (ii) 7keto imparted greater thermo-induced membrane dynamics than 7β, (iii) 7b and 7keto vesicles synergistically, were more thermo-responsive than the individual oxysterols, (iv) the thermo-responsiveness of 7keto-containing vesicles was equivalent to that of 25 hydroxycholesterol (25OH)-containing vesicles, In addition, we carried out langmuir monolayer experiments using the membrane systems above. The results show an increase in molecular area with increase in temperature. and correlated well with the membrane dynamics upon temperature change. These results are important to understanding mechanisms of membrane dynamics upon oxidative stress. The interplay between cholesterol oxidation and temperature provides new ideas for development of oxidative stimulus-dependent therapeutics, including thermo therapy.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130097700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have developed culture methods for reconstructing bile canaliculi (BC) and bile ducts (BDs) formed by small hepatocytes (SHs) which are hepatic progenitor cells, and biliary epithelial cells (BECs), respectively. To study the mechanism of biliary excretion, we need to establish a co-culture system for SHs and BECs. A limitation of conventional culture methods in investigating the mechanisms of hepato-biliary connections is the difficulty to observe the dynamic interactions between SHs and BECs in culture. In addition, patterned constructs do not form in conventional cultures due to the lack of organization of cells. A system that allows more complex dynamics between SHs and BECs to occur is needed in order to investigate the interactions between these cell types. Here, we present an approach called Microfluidic Hydrostatic Deposition Patterning (MHDP) that patterns SH and BEC colonies with defined shape and position, which promotes productive interactions between the cells and eventually induce the formation of heterogeneous tissues integration which is thought to be a prototype of complete biliary networks.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"1102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122918631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
