The reported approach was able to detect informative behavioral details and further prove stress incubation after acute psychological trauma in mice. Standard analyses, in contrast, gave inconclusive results. This approach provides a technical advance allowing exploration of a wide range of potential measurements using standard behavioral tests, and a more solid basis supporting the concluded animal emotionality.","PeriodicalId":122969,"journal":{"name":"2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128444806","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}

It is critical for application service in cloud computing to provide precise information. Ontology servicing is one of the methods to deal with semantic ambiguity and information overload efficiently through appropriate semantic models and semantic technology. This system is the advanced and extended version of the system we have been published before. The experiments reveal that even the testing documents increased; the system may actually be able to produce useful result for text document clustering. In this paper, we propose a cloud service that exploits a novel ontology-based technique for identifying cloud service to improve the accuracy of cloud services searching. Our approach has the capability to perform cloud service concepts from cloud service sources.

Ozden","doi":"10.1109/ICIIBMS.2017.8279731","DOIUrl":"https://doi.org/10.1109/ICIIBMS.2017.8279731","url":null,"abstract":"Parkinson's disease is a neurodegenerative disorder with severe motor deficits such as bradykinesia, muscle rigidity, tremor at rest and abnormal posture. From neurophysiological perspective, the most prominent feature of Parkinsonian pathophysiology is enhanced beta-band power (1340 Hz beta oscillations) in the local field potentials (LFPs) in motor cortex and in several basal ganglia nuclei. Currently, the most effective treatment for advanced Parkinson's disease is the electrical deep brain stimulation (eDBS) targeting at the subthalamic nucleus or internal globus pallidus, in which electrical current at about 125 Hz is continuously injected in to the target area. Even though eDBS significantly alleviates motor symptoms of the disease, it does not provide a complete cure. Therefore, there have been ongoing efforts to develop more effective brain stimulation paradigms, e.g. exploration of alternative areas for stimulation, or employment of advanced stimulation paradigms. A major obstacle against these efforts has been the ambiguities associated with electrical stimulation. Due to nonspecific nature of electrical stimulation and its incompatibility with simultaneous electrophysiology, it has been challenging to fine tune stimulation parameters and target specific neuronal groups or circuits with eDBS. In this work, we demonstrate optogenetics-based brain stimulation as a potential alternative to electrical brain stimulation in the treatment of Parkinson's disease. Optogenetics, with its cellular specificity and compatibility with electrophysiology, offers unique opportunities to monitor the neural activity while modulating the activity of targeted neuronal populations. In our study, we address two important premises for assessment of an optogenetics-based therapeutic brain stimulation paradigm: (1) validation of therapeutic value of precisely targeted deep brain optogenetic modulation; (2) demonstration of potential benefits of spatiotemporally patterned optogenetic stimulation of the motor cortex by characterizing the spatiotemporal dynamics of pathological cortical beta-band activity. In 6-OHDA-induced hemi-Parkinsonian rat model, we used excitatory opsins (ChR2 and C1V1) or inhibitory opsins (iC1C2 and NpHR) to excite or inhibit the subthalamic nucleus. Neural activity across motor cortex was recorded with microelectrode arrays (MEAs, 400μm electrode pitch) implanted unilaterally (6×6 MEA) or bilaterally (two 5×5 MEAs) into the anterior forelimb area of motor cortices. Recording/stimulation sessions were performed during free behavior or during behavioral assays (e.g. amphetamine-induced rotation and mobility test) to quantify and compare therapeutic efficacies of optogenetic stimulation and eDBS. The spatiotemporal dynamics of LFPs were examined with spectral, correlation, and coherence analyses. Our data confirmed the motor deficits such as akinesia and rotational bias in h-P rats. eDBS of subthalamic nucleus improved these motor deficits t","PeriodicalId":122969,"journal":{"name":"2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133478442","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}

The authors have been developing methods to assess mental health status by voice. Analysis using voice has benefits such as, noninvasive, not necessary any specialized device, easy use, and remote-able monitoring. We focused on the pattern of voice frequency during in daily life telephone calls, and developed the Mind Monitoring System (MIMOSYS) which is the smartphone application to monitor the mental health status by voice during telephone calls. MIMOSYS uses voice emotion recognition technology (ST: Sensibility Technology) and outputs “Vitality” which is the indicator to denote the health status immediately after the telephone call and “Mental Activity” which is the indicator to denote the mid-to long-term health status. Higher vitality and Mental Activity values represent a better mental health status. We expect that the user can avoid behavior mental condition due to inducing behavior change, for example depression state, by monitoring mental health status daily using MIMOSYS. When using MIMOSYS, it is desirable to avoid noise as much as possible during telephone calls because empirically at least 7 utterances or more are appropriate for calculating the vitality and it is difficult to correctly detect utterances if noise is contained in the voice. However, environmental sounds will be included when talking in a hands-free manner, and it may cause analyzed results of incorrect mental health status because of unreliable vitality. In this study, we investigate the impact of various noises on the mental health status output by our voice analysis method. We used the sound corpus CENSREC-1-C provided by Speech Resources Consortium in the experiment. This corpus consists of two kinds of data, the simulated data by the noise-addition and the recording data in real environments. One voice data is a numeric string vocalized with several intervals and includes nine or ten utterances. The simulated data includes eight kinds of noise, such as Subway, Babble, Car, Exhibition, Restaurant, Street, Airport and Station. In each noisy environment, noises at SNRs from 20dB to −5dB every 5 dB increments are artificially added to clean voice data without noise. The number of speaker is 104 in this data set. The real environmental data includes two real-noisy environments, such as the university restaurant and the vicinity of highway. In each real environment, there are two SNR conditions, the lower and higher SNR conditions. Furthermore, voice data was recorded with close microphone and remote microphone synchronously in real environments. The number of speaker is 10 in this data set, Voice analysis was performed for both voice data sets. We used only “vitality” for this research because the data have only one time point data. As a result for the simulated data, the mean of vitality values for voice data at SNR of 20dB was lower than it for clean voice data in each environment, and the me","PeriodicalId":122969,"journal":{"name":"2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132698801","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}

Mizuguchi","doi":"10.1109/ICIIBMS.2017.8279749","DOIUrl":"https://doi.org/10.1109/ICIIBMS.2017.8279749","url":null,"abstract":"A better understanding of biological processes, pathways and functions requires reliable information about protein-protein interactions (PPIs). However, it is still a difficult task to identify complete PPI-networks experimentally in a cell or organism. To supplement the limitations of current experimental techniques, we have proposed PSOPIA, a computational method to predict whether two proteins interact or not (http://mizuguchilab.org/PSOPIA/) [1]. The selection of datasets is a big issue for the PPI prediction [2, 3]. It is generally believed that increasing the size and diversity of examples makes the dataset more representative and reduces the noise effects; however, for many algorithms, it is impractical to use a large-scale dataset at the proteome level because of the memory and CPU time requirements. In this study, PSOPIA was retrained on a highly imbalanced large-scale dataset having a diverse set of examples at the proteome level. The dataset consisted of 43,060 high confidence direct physical PPIs obtained from TargetMine [4] (as positives being only 0.13% of the total) and 33,098,951 negative PPIs. As a result, the new prediction model achieved the higher AUC of 0.89 (pAUCfpr<o.5% = 0.24) than the previous model of PSOPIA. Furthermore, it was applied to the problem of filtering out protein pairs incorrectly determined as interacting (false positives) from a low-confidence human PPI dataset. Here, we suggest that a diverse set of large-scale examples is a key toward more reliable PPI prediction, demonstrating the performance of PSOPIA at the proteome level.","PeriodicalId":122969,"journal":{"name":"2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116192199","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}

Systems metabolic engineering for microbial community redesign is a promising approach. The successful development of synthetic microbial communities is essential to add value to the main challenges for sustainable development, such as difficulties to cultivate bacteria in isolation[1], diversity of microbial communities, and many uncharacterized bacteria. Some of these challenges could be addressed by advances in computational tools and modelling. However, current tools only provide separate taxonomic [2] and functional analyses [3]. Development of a metagenomic analysis tool to investigate metagenomes deeply with the help of integrated taxonomic, functional and metabolic pathways analyses may allow to make community modelling and study complex interspecific relations inside the community. This would help finding ways to increase the functional potential of microbial communities either by optimizing external conditions and nutrients or by regulating the taxonomic content and proportions of the bacterial composition.","PeriodicalId":122969,"journal":{"name":"2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125658910","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}
