This paper proposes a new kind of visual marker for a wearable computer based Augmented Reality (AR) system. Various marker systems have already been developed for using with an AR system. However, the improvement is needed to use these marker systems on a wearable AR system in terms of the amount of information or the width of the recognizable area. The(More)
Recent activities carried out under auspices of the WPEC Subgroup 24, or those closely related to the subgroup , are summarized. The major efforts were addressing formal studies and implementation of the newly proposed Unified Monte Carlo method, comparison of existing approaches (KALMAN, Monte Carlo, Backward-Forward Monte Carlo, and GANDR), establishing(More)
In order to record multi-site electroretinogram (ERG) responses in isolated carp retinae, we utilized three-dimensional (3D), extracellular, 3.5-μm-diameter silicon (Si) probe arrays fabricated by the selective vapor-liquid-solid (VLS) growth method. Neural recordings with the Si microprobe exhibit low signal-to-noise (S/N) ratios of recorded responses due(More)
Very fine needle-electrode arrays potentially offer both low invasiveness and high spatial resolution of electrophysiological neuronal recordings in vivo. Herein we report the penetrating and recording capabilities of silicon-growth-based three-dimensional microscale-diameter needle-electrodes arrays. The fabricated needles exhibit a circular-cone shape(More)
The Subgroup A activities focus on the development of nuclear reaction models and codes, used in evaluation work for nuclear reactions from the unresolved energy region up to the pion threshold production limit, and for target nuclides from the low teens and heavier. Much of the efforts are devoted by each participant to the continuing development of their(More)
SUMMARY This document serves as a summary of the work of Subgroup 20 (SG20) on covariance matrix evaluation and processing in the resolved / unresolved resonance regions, organized under the Nuclear Energy Agency's Nuclear Science Committee Working Party on International Evaluation Cooperation (WPEC). The work described in this report focuses on: (1)(More)
In this paper, a co-design method and a wafer-level packaging technique of a flexible antenna and a CMOS rectifier chip for use in a small-sized implantable system on the brain surface are proposed. The proposed co-design method optimizes the system architecture, and can help avoid the use of external matching components, resulting in the realization of a(More)
Covariance matrix evaluations in the fast energy range were performed for a large number of actinides, either using low-fidelity techniques or more sophisticated methods that rely on both experimental data as well as model calculations. The latter covariance evaluations included in the ENDF/B-VII.1 library are discussed for each actinide separately.
BACKGROUND This study was conducted to investigate how various irrigation fluids used during neurosurgical procedures affect the degree of postoperative brain edema and cellular damage during experimental neurosurgery in rats. METHODS The cerebral cortex was exposed and incised crosswise with a surgical knife under irrigation with an artificial CSF,(More)
