Future robots/agents will perform situated behaviors for each user. Flexible behavioral learning is required for coping with diverse and unexpected users' situations. Unexpected situations are usually not tractable for machine learning systems that are designed for pre-defined problems. In order to realize such a flexible learning system, we were trying to create a learning model that can function in several different kinds of state transitions without specific adjustments for each transition as a first step. We constructed a modular neural network model based on reinforcement learning. We expected that combining a modular architecture with neural networks could accelerate the learning speed of neural networks. The inputs of our neural network model always include not only observed states but also memory information for any transition. In pure Markov decision processes, memory information is not necessary, rather it can lead to lower performance. On the other hand, partially observable conditions require memory information to select proper actions. We demonstrated that the new learning model could actually learn those multiple kinds of state transitions with the same architectures and parameters, and without pre-designed models of environments. This paper describes the performances of constructed models using probabilistically fluctuated Markov decision processes including partially observable conditions. In the test transitions, the observed state probabilistically fluctuated. The new learning model could function in those complex transitions. In addition, the learning speeds of our model are comparable to a reinforcement learning algorithm implemented with a pre-defined and optimized table-representation of states.

Did Cicero intend his statesman to be understood as a 'new concept' (K. Büchner) when he called him tutor et procurator rei publicae and rector et gubernator civitatis (2.51)?Now numerous instances before and with Cicero of similar metaphors and their combinations applied to political activities make it quite clear that there is nothing new insofar as these phrases are concerned. So in view of their well-known metaphorical character 'minus......tritum sermone nostro' (2.51) should not be translated by 'not frequently used in our language i.e. Latin' but by 'not fully treated in our conversa-tion'.The study of the passages concerning the role of this statesman suggests too that it is chiefly based on auctoritas and is not appreciably different from that of the principes of the Roman republic. It is, however, very remarkable that the analogy of the reason swaying and controlling the mind, by which the imperium of a monarch is explained, seems also to have been used to describe the activities of this statesman (2.67ff.). Cicero, while conceding the superiority to the mixed form of constitution, maintains that monarchy is to be preferred to the other unmixed forms because of, among others, the fact that there will be no imperium at all unless it remains a unit. It could be inferred from this that what Cicero, when using this analogy, had in mind was a statesman who, while acting on auctoritas (2.69: ut sese......sicut speculum praebeat civibus), would be the sole leader in the state. This semi-monarchistic role is, however, clearly incompatible with the principles of the mixed form of constitution which Cicero pronounces the best and sees embodied in the Roman republic. This inconsistency, if it may be called so, could have resulted from his theorizing on an ideal statesman in line with Greek political theories while retaining him in the framework of the Roman republic.Now this statesman is set in opposition to a tyrant who is nothing but a deteriorated form of monarchy as is illustrated by the Roman history. This transformation of the best single form into the worst is most typical of all political changes. The mixed form, according to the Greek theories (mainly Polybios) outlined in the De re publica, is the most effective in maintaining equality and stability and thus preventing any change for the worse because it combines and balances the elements of the three unmixed forms; whereas Cicero sees the vital factor of stabilization in the statesman who cares for the practical interests and the self-respect of his fellow-citizens, foreseeing dangerous changes and taking necessary steps against them. Here Cicero, while following a familiar pattern of political discussions where a tyrant or tyranny is contrasted with a just king or other forms of constitution, reserves for his statesman a leading role in renewing and preserving the Roman state, and all who are present in the conversation are urged to become like him (2.45) since he is an exemplum (2.69), a model to be followed by all his fellow-citizens.The impression thus gained would be that of a 'new' statesman, but he remains nonetheless a traditional i. e. republican princeps, presented as he is in an idealized form. This method of theorizing on the traditional institutions (mos maiorum), idealizing and presenting them as exempla, is used again in the De legibus which was probably begun as soon as, or before, the De re publica was finished.It is not clear whether Augustus was influenced by Cicero's concept of this statesman. Granting that he adopted for his principate the latter's concept, then he pretended it was not new, for he emphasized his role in having restored the Roman republic and posed as a traditional princeps acting on auctoritas. In reality, however, his principate was nothing other than a kind of monarchy, a novus status, as Suetonius called it.

Hepatitis E virus (HEV) infection has previously been reported in wild mongooses on Okinawa Island; to date however, only one HEV RNA sequence has been identified in a mongoose. Hence, this study was performed to detect HEV RNA in 209 wild mongooses on Okinawa Island. Six (2.9%) samples tested positive for HEV RNA. Phylogenetic analysis revealed that 6 HEV RNAs belonged to genotype 3 and were classified into groups A and B. In group B, mongoose-derived HEV sequences were very similar to mongoose HEV previously detected on Okinawa Island, as well as to those of a pig. This investigation emphasized the possibility that the mongoose is a reservoir animal for HEV on Okinawa Island.

Artificial skin having human skin-like texture is necessary for the development of tactile evaluation systems and for robots that have physical contact with humans. This paper describes a novel type of artificial skin having human skin-like texture and a model of human texture perception. The artificial skin is designed by emulating the surface shape pattern and elastic structure of the human skin. Appropriate wettability and friction property of the artificial skin is achieved by designing the surface shape. Through sensory evaluation, we confirm the artificial skin has human skin-like texture due to its surface shape pattern and elastic structure. In addition, we build a model of skin-like texture perception through multivariate analysis between physical parameters and tactile factor scores. This model can indicate what factor is important for human skin-like texture. From the results, artificial skin having optional skin-like texture can be developed

Factor analysis of semantic differential data, with forty-eight cases of collegiate lecture rooms psychologically assessed by students during regular classes, has established that distance evaluation forms diagonal coordinates together with overall evaluation. Multiple regression analysis has then explained psychological distance in five variables: room depth, natural lighting, illumination, window-opening ratio and student density. The ratio of room depth to breadth and main window area on both sides are also explanatory variables, supporting hypotheses of tunnel effect and window-frame rhythms as increasing factor. A multiple-regression equation explaining 69.4% of variance has revealed that 100~180 lx increase of illumination should compensate 1.8m decrease in room depth.

Ubiquinol-10 (QH2), the reduced form of Coenzyme Q10 (CoQ10) serves as a potent antioxidant of lipid membranes. Because many antioxidants reveal potent anti-inflammatory effects, the influence of QH2 on lipopolysaccharide (LPS)-induced pro-inflammatory cytokines and chemokines were determined in the human monocytic cell line THP-1. Stimulation of cells with LPS resulted in a distinct release of Tumour necrosis factor-alpha (TNF-α), Macrophage inflammatory protein-1 alpha (MIP-1α), Regulated upon activation, normal T cell expressed and secreted (RANTES) and Monocyte chemotattractant protein-1 (MCP-1). The LPS-induced responses were significantly decreased by pre-incubation of cells with QH2 to 60.27 ± 9.3% (p = 0.0009), 48.13 ± 6.93% (p = 0.0007) and 74.36 ± 7.25% (p = 0.008) for TNF-α, MIP-1α and RANTES, respectively. In conclusion, our results indicate anti-inflammatory effects of the reduced form of CoQ10 on various proinflammatory cytokines and chemokines in vitro.

In this study, we investigated the taxonomic diversity of actinomycetes isolated from swine manure compost that had undergone self-heating. Pretreatment with sodium dodecyl sulfate and subsequent cultivation of the compost sample on humic acid-vitamin agar at 30 and 50°C resulted in the selective isolation of 125 actinomycete strains. These isolates were classified using a combination of morphological characterization and 16S rDNA sequence analysis, with sequence similarities of ≥97% and ≥99% used to identify isolates at genus and species level, respectively. The isolated actinomycete assemblage consisted of a diverse array of species, with the 125 isolates falling into 10 families, 15 genera, and 22 species. The most dominant thermophilic actinomycetes were Saccharomonospora (Sam.) viridis and Thermobifida fusca, followed by Actinomadura spp. Other species that were frequently isolated at 30°C included Glycomyces spp., Nocardiopsis (Nop.) alba, Nop. composta, Rhodococcus rhodochrous, and Sam. azurea.

終末期がん患者における輸液量と呼吸困難・気道分泌との関連性を明らかにすることを目的として後ろ向き研究を行った. 悪性新生物により死亡した138例を対象とし, 死亡前1週の輸液量1,000 ml/日以下の少量群85例と1,001 ml/日以上の多量群53例に分けて呼吸困難と気道分泌の有無を比較した. また, これらの症状に影響のある因子を多変量解析で求めた. 呼吸困難と気道分泌は多量群の64.2%, 52.8%にみられ, 少量群(32.9%, 15.3%)と比較して有意に高値であった. 呼吸困難に関連していたのは肺病変(オッズ比3.55), 輸液1,001 ml/日以上(3.54), オピオイド投与(0.40)で, 気道分泌では肺病変(7.29), 輸液1,001 ml/日以上(4.43), 食事摂取(0.31)であった. 過量な輸液が呼吸器症状に影響を及ぼすことが示唆され, 1,000 mlを超えない輸液が1つの目安と考えられた.

To minimize the risk of fatalities in the event of earthquakes, it is extremely important to prevent the derailed vehicle from deviating from the track as well as to prevent the vehicle from derailment. Authors have developed a post derailment stopper (hereinafter referred to as, “stopper”), which attaches to a bogie frame and prevents derailed vehicles from veering of the track. For the development of the stopper and evaluation of its efficacy, we conducted running tests under derailment conditions using real bogies and tracks. Based on the results of the running tests, we have developed a 15DOF vehicle dynamics model in order to discuss the motion of the bogie in the derailment condition. In this model, focusing on the analysis of the motion of the bogie and the stopper, vertical wheel displacements which were measured at the running tests are used as input data and non-linear characteristics observed at the running tests are considered. In this paper, we analyze the motion of the bogie and efficacy of the stopper with this model and the test results.

神経回路ができるとき,神経突起が標的細胞と接着することでシナプス結合が成立する.神経回路が成立したあとでも,シナプス形成過程の一部をくりかえすことで,シナプスの強化・抑圧やつなぎかえが起きる.我々は,これらの過程に接着分子カドヘリンが関与する可能性を検討してきた.研究を進める中で,カドヘリンが思いのほかダイナミックにシナプスの生理機能にかかわることがわかり,さらにその過程で新たなシグナル伝達経路も見いだされた.こうしてわかってきた事実は,神経回路のなりたちや可塑性に新たな視点を与えるばかりでなく,カドヘリンが神経伝達物質の放出機構や受容体の機能調節に深くかかわっている可能性も示唆している.またカドヘリン遺伝子の異常は,自閉症などの疾患感受性に関連しており,シナプスの接着・リモデリング関連分子は,新たな治療標的として薬理学への貢献が期待される.
