    This paper discusses the use of distributed middlewares as essential tools for facilitating electronic exchange of standard business document between managers, financial institutes, and trading partners in the banking sector. Internally, companies can benefit by creating information architectures that allow systems to easily exchange data. One less expensive and disruptive option that applies to most banks/financial institutes is used traditional mainframe (legacy) system with an array of distributed middlewares to overcome the aforementioned limitations. This paper focuses on developing a new distributed processing architecture based on client-server technology called UAIF – Unified Accounting Information Framework. UAIF is designed to assist managers/financial institutes with a transparent access to information anywhere on the LAN or WAN from any desktop and to meet management specific needs so that some of the accounting and financial works can be widely used for World Wide Web (WWW) applications via Internet or Intranet.  For concept verification, we utilize UAIF to modeling a bank accounting system, which is based on an industrial standard CORBA architecture, XML and OMG General Ledger Facility. This methodology integrates enterprise accounting information system (AIS) with distributed systems via Internet, Intranet, and Electronic Commerce

    Multi-shelled hollow metal oxide nanostructures have attracted tremendous attention in energy storage devices owing to their high specific capacity, rate capability and ameliorated cycling performance. Although great progress has been made in synthesizing multi-shelled hollow structures, most methods still depend on tedious template mediated strategies to generate complex interior structures. Herein, we developed a facile universal self-templated approach to synthesize a series of multi-shelled hollow metal oxide spheres with tailored compositions. This strategy involved the solvothermal preparation of uniform spherical coordination polymers (CPs) as precursors and a subsequent thermal treatment in air. Single-, binary- and ternary-metal multi-shelled hollow oxide spheres (Co, Mn-Co, Ni-Co, Ni-Co-Mn, etc.) were successfully obtained. To demonstrate their applications in energy storage, the electrochemical properties of ZnCo2O4 were investigated by testing the lithium-ion-storage performance. Owing to the unique structures, the multi-shelled hollow ZnCo2O4 spheres exhibited high specific capacity, excellent cycling durability (1200 mA h·g-1 after 200 cycles at 0.1 A g-1) and prominent rate capability (730 mA h·g-1 at 5.0 A g-1)

    Handwriting velcro: Endowing AR glasses with personalized and posture-adaptive text input using flexible touch sensor

    Get PDF
    Text input is a desired feature for AR glasses. While there already exist various input modalities (e.g., voice, mid-air gesture), the diverse demands required by different input scenarios can hardly be met by the small number of fixed input postures offered by existing solutions. In this paper, we present Handwriting Velcro, a novel text input solution for AR glasses based on flexible touch sensors. The distinct advantage of our system is that it can easily stick to different body parts, thus endowing AR glasses with posture-adaptive handwriting input. We explored the design space of on-body device positions and identified the best interaction positions for various user postures. To flatten users' learning curves, we adapt our device to the established writing habits of different users by training a 36-character (i.e., A-Z, 0-9) recognition neural network in a human-in-the-loop manner. Such a personalization attempt ultimately achieves a low error rate of 0.005 on average for users with different writing styles. Subjective feedback shows that our solution has a good performance in system practicability and social acceptance. Empirically, we conducted a heuristic study to explore and identify the best interaction Position-Posture Correlation. Experimental results show that our Handwriting Velcro excels similar work [6] and commercial product in both practicality (12.3 WPM) and user-friendliness in different contexts

    Abstract(#br)A convenient and fast strategy to construct multistage spherical LiNi 0.5 Mn 1.5 O 4 by coprecipitation and following gradient temperature calcination has been developed. Considering about the effect of reaction kinetics, ethanol and water were used as co-solvent to accelerate the crystallite nucleation and reduce the reaction time. The precursors could be obtained within an hour with ethanol/water proportion of 1:3. Due to the synergistic effect of nanoscale primary particles and assembled micro-spheres of hierarchical LiNi 0.5 Mn 1.5 O 4 product, the material showed high electrochemical properties as cathode for lithium ion batteries. The cathode delivered 141 mAh g −1 at 1 C and maintained 94.2% after 200 cycles. Even at 10 C, 114 mAh g −1 could be retained. Furthermore, the full cell with Li 4 Ti 5 O 12 delivered 132.4 mAh g −1 at 1 C and kept 92.4% retention after 200 cycles. And the product at 55 °C also exhibited 133.2 mAh g −1 at 1 C and kept 93.2% after 100 cycles

    Corneal dendritic cells in diabetes mellitus: A narrative review

    Get PDF
    Diabetes mellitus is a global public health problem with both macrovascular and microvascular complications, such as diabetic corneal neuropathy (DCN). Using in-vivo confocal microscopy, corneal nerve changes in DCN patients can be examined. Additionally, changes in the morphology and quantity of corneal dendritic cells (DCs) in diabetic corneas have also been observed. DCs are bone marrow-derived antigen-presenting cells that serve both immunological and non-immunological roles in human corneas. However, the role and pathogenesis of corneal DC in diabetic corneas have not been well understood. In this article, we provide a comprehensive review of both animal and clinical studies that report changes in DCs, including the DC density, maturation stages, as well as relationships between the corneal DCs, corneal nerves, and corneal epithelium, in diabetic corneas. We have also discussed the associations between the changes in corneal DCs and various clinical or imaging parameters, including age, corneal nerve status, and blood metabolic parameters. Such information would provide valuable insight into the development of diagnostic, preventive, and therapeutic strategies for DM-associated ocular surface complications

    Potential of Core-Collapse Supernova Neutrino Detection at JUNO

    Get PDF
    JUNO is an underground neutrino observatory under construction in Jiangmen, China. It uses 20kton liquid scintillator as target, which enables it to detect supernova burst neutrinos of a large statistics for the next galactic core-collapse supernova (CCSN) and also pre-supernova neutrinos from the nearby CCSN progenitors. All flavors of supernova burst neutrinos can be detected by JUNO via several interaction channels, including inverse beta decay, elastic scattering on electron and proton, interactions on C12 nuclei, etc. This retains the possibility for JUNO to reconstruct the energy spectra of supernova burst neutrinos of all flavors. The real time monitoring systems based on FPGA and DAQ are under development in JUNO, which allow prompt alert and trigger-less data acquisition of CCSN events. The alert performances of both monitoring systems have been thoroughly studied using simulations. Moreover, once a CCSN is tagged, the system can give fast characterizations, such as directionality and light curve

    Detection of the Diffuse Supernova Neutrino Background with JUNO

    Get PDF
    As an underground multi-purpose neutrino detector with 20 kton liquid scintillator, Jiangmen Underground Neutrino Observatory (JUNO) is competitive with and complementary to the water-Cherenkov detectors on the search for the diffuse supernova neutrino background (DSNB). Typical supernova models predict 2-4 events per year within the optimal observation window in the JUNO detector. The dominant background is from the neutral-current (NC) interaction of atmospheric neutrinos with 12C nuclei, which surpasses the DSNB by more than one order of magnitude. We evaluated the systematic uncertainty of NC background from the spread of a variety of data-driven models and further developed a method to determine NC background within 15\% with {\it{in}} {\it{situ}} measurements after ten years of running. Besides, the NC-like backgrounds can be effectively suppressed by the intrinsic pulse-shape discrimination (PSD) capabilities of liquid scintillators. In this talk, I will present in detail the improvements on NC background uncertainty evaluation, PSD discriminator development, and finally, the potential of DSNB sensitivity in JUNO

    Bank's risk-taking and ownership structure - evidence for economics in transition stage

    No full text
    Conventional studies assume that inside management plays a major role in corporate governance and argue that foreign institutional investors may lack incentives to monitor invested firms due to their short-term profit orientation. By utilizing 650 observations of Taiwan banks, this study examines the effects of specific types of ownership on the risk-taking behaviours of banks under differential ownership structures. In light of the increasing foreign institution ownership during privatization, this article further constructs relative governance strength variables to observe how inside management and foreign institutions interact to affect these banks' risk-taking. The results show that banks with higher inside management ownership and higher government ownership have higher overdue loan and lower capital adequacy ratios. Banks with higher foreign institution ownership and stronger relative governance strength are associated with lower overdue loans and higher regulatory capital. In general, the results are consistent regardless of the choice of ownership structure or relative governance strength of foreign institutions as independent variable. These findings contribute to add evidence for risk-taking behaviour manifested by banks in the emerging market, where feasible monitoring mechanisms still need to be explored.
