Audio-visual neural interaction was examined by using ERPs. Eleven male volunteers participated in this study. EEGs were recorded from 19 locations. Japanese vowels (/a/ or /i/) or white-noise (/noise/) were used as auditory stimuli. The face images pronouncing vowel ([a] or [i]) were used as visual stimuli. This study was composed of three conditions, i.e., (1) audio-visual condition (AV condition) due to bimodal stimulus presentation, (2) auditory condition (A condition) due to only auditory stimulus presentation, and (3) visual condition (V condition) due to only visual stimulus presentation. In the AV condition, audio-visual stimuli pairs were phonetically congruent (audio/a/, visual[a]), incongruent (audio/a/, visual[i]), and deviant (/noise/, visual[a]). The participants were instructed to press a button for vowel/a/ or /noise/ stimulus. Audio-visual interaction was examined by subtracting ERPs in the A or V condition from ERPs in the AV condition. Cross-modal facilitatory effects were not observed in auditory perception. On the other hand, topographical changes occurred in face-specific negative components around 170 ms depending on audio and visual informational congruency, i.e., the center of negative activity shifted towards the left hemisphere for "incongruent" stimulus. This result might be concerned with suppression of incongruent visual information. © 2012 IEEE.

To facilitate pronuclear microinjection, we have been developing the Vibratory Microinjection Systems (VMSs) that provides a micropipette with longitudinal vibration. The current VMS utilizes any frequency up to 100 kHz. We compared 35-kHz vibratory microinjection (VM) with ordinary microinjection (OM). Fourteen micropipettes were used to inject 420 BDF1 zygotes. Each micropipette finished its injection quota of 30 eggs, which were manipulated one by one alternately using the two types of microinjections, even when it repeatedly pulled out nuclear components. All microinjections were conducted at a compensation pressure of 30 hPa and digitally recorded for subsequent image analysis. VM resulted in slightly better embryonic development in 4-day culture than OM, but significantly shortened the time spent on microinjection and the time spent swelling the pronucleus by 25% and 30%, respectively. These pronuclear swelling times, together with the almost identical degrees of pronuclear swelling in both groups, suggested that VM injected a GFP solution at a 42% higher speed. VM significantly reduced the incidence of pulling out nuclear components, suggesting VM's capability of removing the nuclear components already adhering to the micropipettes. These results indicate VMS is a useful option which is capable of raising the efficiency of microinjection significantly by saving time, labor and cost of microinjection. © 2012 Japanese Society of Mammalian Ova Research.

This paper presents an application of evolutionary fuzzy classifier design to a road accident data analysis. A fuzzy classifier evolved by the genetic programming was used to learn the labeling of data in a real world road accident data set. The symbolic classifier was inspected in order to select important features and the relations among them. Selected features provide a feedback for traffic management authorities that can exploit the knowledge to improve road safety and mitigate the severity of traffic accidents. © 2012 IEEE.

There is good evidence that naltrexone, an opioid antagonist, has a strong neuroprotective role and may be a potential drug for the treatment of fibromyalgia. In previous work, some of the authors used experimental clinical data to identify input-output linear time invariant models that were used to extract useful information about the effect of this drug on fibromyalgia symptoms. Additional factors such as anxiety, stress, mood, and headache, were considered as additive disturbances. However, it seems reasonable to think that these factors do not affect the drug actuation, but only the way in which a participant perceives how the drug actuates on herself. Under this hypothesis the linear time invariant models can be replaced by State-Space Affine Linear Parameter Varying models where the disturbances are seen as a scheduling signal signal only acting at the parameters of the output equation. In this paper a new algorithm for identifying such a model is proposed. This algorithm minimizes a quadratic criterion of the output error. Since the output error is a linear function of some parameters, the Affine Linear Parameter Varying system identification is formulated as a separable nonlinear least squares problem. Likewise other identification algorithms using gradient optimization methods several parameter derivatives are dynamical systems that must be simulated. In order to increase time efficiency a canonical parametrization that minimizes the number of systems to be simulated is chosen. The effectiveness of the algorithm is assessed in a case study where an Affine Parameter Varying Model is identified from the experimental data used in the previous study and compared with the time-invariant model.

As the rapid growth of smart phone technology, people have a lot of digital image information such as digital photos or videos. Both data hiding and data compression are very important technologies in image processing field. On the overview, it seems that there is no relationship between data hiding and data compression because data hiding mechanisms focus on information security and data compression mechanisms emphasize the compression ratio. However, the more secret data is embedded, the more capacity the stego image increases. Actually, they are closely related. Until now, there are many literatures to discuss the secret data how to be embedded into the media image and keeps the original capacity as soon as possible. In this paper, a reversible data hiding scheme based on EMD data hiding and JPEG (Joint Picture Experts Group) compression technology will be proposed. According to experimental results, the authors can prove that our proposed scheme maintains high embedding capacity, security and good compression ratio.

Ultrafine elongated grain (UFEG) structures with strong 〈110〉// rolling direction (RD) fiber deformation texture were produced by warm caliber-rolling at 773 K, namely tempforming in the 1200 MPa-class medium-carbon low-alloy steel with phosphorous (P) contents of 0.001 and 0.053 mass%. Charpy impact tests were performed at temperature range of -196 to 150 °C on the UFEG structure. Regardless of P content, high upper shelf energy about 145 J and a very low ductile to brittle transition temperature (DBTT) of around -175 °C were obtained. P segregation embrittlement completely disappeared in the 0.053 %P steel and both steels showed ductile fracture on the planes normal to RD at temperature range of -150 to 150 °C. The main reason for the high upper shelf energy and very low DBTT in the 0.053 %P steel would be delamination fracture along RD when both 0.001 and 0.053 %P steels showed quite similar microstructures including texture. Since the occurrence of delamination requires relatively weak interfaces or planes, P segregated to the ferrite grain boundaries and interfaces of cementite particles-ferrite matrix and made them feasible paths for crack branching and consequently delamination occurred. We showed in this work the advantage of delamination (crack arrester-type) on the high absorbed energy obtained by 0.053 %P steel in comparison with 0.001 %P steel. © (2012) Trans Tech Publications, Switzerland.

There has been a considerable increase in the population proportion of senior people among global population. Fall often happens among these senior people, which is also the leading cause of their death. A real-time fall detection system may help us to detect fall events among elderly people in time and reduce the overall casualty rate. This paper proposed a home-based, real-time fall detection system that not only can distinguish up to 4 different kinds of fall events (forward, backward, rightward and leftward), but is also portable, low-cost and with high accuracy rate. The system includes a real-time fall detection band, a home server, and GSM instant messaging function which can transfer fall alert, send emergency help messages.

Many organizations have now adopted Service Oriented Architecture （SOA） as an architectural style to help them with architecture, design and implementation of their core services and systems. Most of these organizations are challenged in integrating SOA style with their overall Enterprise Architecture work. This framework links an SOA style with the Enterprise Architecture （EA） methodologies to help organizations organize their SOA effort as a key part of their Enterprise Architecture. The case study demonstrates the implementation of architecture goal with organization vision in service oriented organizational structure using services that align Business with Technology. The framework is validated and has reserved the privileges of SOA and EA.
