A computational framework is presented for 3-D liver shape approximation and characterization in order to determine the accuracy of shape reconstruction via Spherical Harmonics expansion. Spherical Harmonics is a powerful mathematical tool for expanding the shape. But in medical domain, livers have very variation geometry, in shape, size, and volume. In this regards, we evaluated and optimized the Spherical Harmonics to create 3-D parametric surface of the liver from Computed Tomography (CT) imaging system which may useful for Shape modeling, surface representation, physical measurement of objects and mathematical model. We select randomly 5 livers from more 100 dataset. Mean Hausdorff distance Errors and Dice similarity coefficient DSC by liver volumes was measured. The experimental results showed that the best order of Spherical Harmonics Expansion for livers is between 12~17.

This report summarizes the proceedings of the second workshop of the 'Minimum information for Biological and Biomedical Investigations' (MIBBI) consortium held on Dec 1-2, 2010 in Rüdesheim, Germany through the sponsorship of the Beilstein-Institute. MIBBI is an umbrella organization uniting communities developing Minimum information (MI) checklists to standardize the description of data sets, the workflows by which they were generated and the scientific context for the work. This workshop brought together representatives of more than twenty communities to present the status of their MI checklists and plans for future development. Shared challenges and solutions were identified and the role of MIBBI in MI checklist development was discussed. The meeting featured some thirty presentations, wide-ranging discussions and breakout groups. The top outcomes of the two-day workshop as defined by the participants were: 1) the chance to share best practices and to identify areas of synergy; 2) defining a series of tasks for updating the MIBBI Portal; 3) reemphasizing the need to maintain independent MI checklists for various communities while leveraging common terms and workflow elements contained in multiple checklists; and 4) revision of the concept of the MIBBI Foundry to focus on the creation of a core set of MIBBI modules intended for reuse by individual MI checklist projects while maintaining the integrity of each MI project. Further information about MIBBI and its range of activities can be found at http://***/.

Workflow technologies have become a major vehicle for the easy and efficient development of science applications. At the same time new computing environments such as the Cloud are now avaiable. A challenge is to determine the right amount of resources to provision for an application. This paper introduces an algorithm named Balanced Time Scheduling (BTS), which estimates the minimum number of virtual processors required to execute a workflow within a user-specified finish time. The resource estimate of BTS is abstract, so it can be easily integrated with any resource description language or any resource provisioning system. The experimental results with a number of synthetic workflows demonstrate that BTS can estimate the computing capacity close to the optimal. The algorithm is scalable so that its turnaround time is only tens of seconds even with workflows having thousands of tasks and edges. © 2008 IEEE.

Shih, Tzay-Farn Department of Computer Science and Information Engineering Chaoyang University of Technology Taichung 41349 Taiwan Department of Management Information Systems National Chung Hsing University Taichung 402 Taiwan Innovative Supply-Chain Application Division Identification and Security Technology Center Industrial Technology Research Institute Hsinchu 310 Taiwan

Radio Frequency Identification (RFID) is a new technology. In recent years, it is convenient and feasible in many applications. However, it also addresses many security issues which are worth discussing. The Counterfeit imposes a menace to industry worldwide, and the problem is not specific for certain products or countries. In 2003, Koh et al. describe a RFID system based on "track and trace" solution to apply into pharmaceutical supply chain management to fight the counterfeit. Moreover, there are applications to solve malicious manner were presented. But there always still existed some disputes and not conform Class 1 Generation 2 (C1G2) standards. Unfortunately, the trick is changeable. The Koh et al.'s scheme is at premise rather primitive. In order to tackle this problem, we propose an anti-counterfeit ownership transfer protocol for low cost RFID system. We only use a tag to be a storage media. The proposed scheme can ensure a secure transaction.

Recently, the triple play service (TPS) has been considered to be a promising business model or application. Thus, the capability for multicast transmission has become a very important requirement for access networks. However, unlike existing passive optical networks (PONs), the arrayed-waveguide grating (AWG) based wavelength-division multiplexing (WDM)-PON does not have multicast capability because it is a P2P network for the downstream direction, from optical line terminal (OLT) to optical network units (ONUs). In this paper, AWG-based WDM-PON architecture with multicast capability is proposed. It provides high scalability and single copy broadcast (SCB) capability by employing multi-stage AWGs at a remote node (RN) and a multi-wavelength converter (MWC) at OLT. The performance of the proposed architecture is evaluated in terms of cost, scalability, link capacity and bandwidth per user, in both upstream and downstream directions, by comparison with other multicasting architectures. ©2008 IEEE.

Nano Drug Delivery System (nano-DDS) is a new medical technology. We studied medical use used by about 7 [nm] ferromagnetic fluids. We searched good energy condition offerrofluid contrast medium radiograph image used by SPring-8 synchrotron radiation X-ray. As results, in case of low photon energy 15.0 [KeV] (λ = 0.8 Å). We showedferrofluid in Acryl amid gel and taro leaf and mugwort. #1. We found Low photon energy could show vascular tissue and ferrofluid distribution respectively. In case of medium photon energy 20.0 [KeV] (λ = 0.6 Å). We observed ferrofluid in rat ear lobe and rat stomach and rat foot. #2. We found medium photon energy could see several organizations by changing exposure. In case of high photon energy 25.0 [KeV] (λ = 0.5 Å). We showed ferrofluid in chicken egg and pork. #3. We found high proton energy was suitable for observing ferrofluid distribution in plain organization, but was not suitable for observing ferrofluid distribution in complicate organization. © 2008 IEEE.

By using the ATLAS detector, observations have been made of a centrality-dependent dijet asymmetry in the collisions of lead ions at the Large Hadron Collider. In a sample of lead-lead events with a per-nucleon center of mass energy of 2.76 TeV, selected with a minimum bias trigger, jets are reconstructed in fine-grained, longitudinally segmented electromagnetic and hadronic calorimeters. The transverse energies of dijets in opposite hemispheres are observed to become systematically more unbalanced with increasing event centrality leading to a large number of events which contain highly asymmetric dijets. This is the first observation of an enhancement of events with such large dijet asymmetries, not observed in proton-proton collisions, which may point to an interpretation in terms of strong jet energy loss in a hot, dense medium.

SPECT using compact high resolution detector or pinhole collimator allows to image physiological functions with high resolution. However, when region-of-interest (ROI) is smaller than the object, the projection data are truncated due to radioisotope outside ROI. The truncation causes artifact and overestimation, which decrease quantitative accuracy. In theory, to eliminate the artifact and the overestimation due to truncation, the untruncated data from another large field-of-view (FOV) detector can be used even if the detector has low resolution. This study was aimed at evaluating feasibility of combination of a small FOV high resolution detector and a large FOV low resolution detector in clinical circumstance. This evaluation was performed by computer simulation with a numerical torso phantom. We tested whether the image in a selected small ROI (in this case, ROI was heart) can be obtained with high resolution and without artifact and overestimation. The small FOV detector with high resolution was with 1.14-mm resolution, 80-mm FOV and parallel collimator. The whole of heart was included in this FOV, but the surrounding area was truncated. The large FOV detector with low resolution has 9-mm resolution, 360-mm FOV and parallel collimator like conventional clinical SPECT. The untruncated projections including the whole of thorax were acquired by this detector. Gaussian noises were added to all projection data. Data from the small detector were reconstructed by maximum likelihood expectation maximization (MLEM) as iterative method, on the reconstruction matrix large enough to contain the whole of thorax. The reconstructed image from the large FOV detector was used as an initial image in iterative reconstruction. The image obtained by our proposed method had high resolution and the counts almost equivalent to that of original image in the small ROI. In conclusion, this result suggests feasibility of the combination of two detectors with small and large FOV to quantitat
