    Brief Announcement: On the Correctness of Transaction Processing with External Dependency

    Get PDF
    We briefly introduce a unified model to characterize correctness levels stronger (or equal to) serializability in the presence of application invariant. We propose to classify relations among committed transactions into data-related and application semantic-related. Our model delivers a condition that can be used to verify the safety of transactional executions in the presence of application invariant

    Important Factors on Sidewalks with Vendor Activities Based on Pedestrian Perception by Gender and Age

    This paper presents an investigation of important factors relating sidewalk performance based on pedestrian perceptions by gender and age. Exploratory factor analysis technique and reliability test of the variables are performed on 45 items of sidewalk current condition in order to extract dimensions of pedestrian perceptions in Jakarta and Bangkok. Based on age, male respondents reveals that eight factors are identified as important on sidewalk performance, and labeled on the basis of the attributed covered as sidewalk interaction, comfort, space availability, safety, vendor problems, walking path, vendor regulation, and vendor's attraction. On the other hand, the first seven factors are similarly stated by female respondents. Grouped by age, young respondents reveal nine factors are considered important and arbitrarily named as comfort, sidewalk interaction, safety, vendor's attraction, vendor problems, vendor regulation, walking path, space availability, and sidewalk condition. The presence of vendors are often deemed as obstruction for walking flow, but their activities should be accommodated by establishing policies and management to accept high performance of the sidewalks and to support the city's economy

    Divisibility of the class numbers of imaginary quadratic fields

    For a given odd integer n>1n>1, we provide some families of imaginary quadratic number fields of the form Q(x2tn)\mathbb{Q}(\sqrt{x^2-t^n}) whose ideal class group has a subgroup isomorphic to Z/nZ\mathbb{Z}/n\mathbb{Z}.Comment: 10 pages, accepted for publication in Journal of Number Theory (2017

    Carbon Nanoarch Encapsulating Fe Nanowire on Ni (111)

    Full text link
    We investigate the stable structures of Fe-filled single-walled carbon nanotubes (SWNTs) on Ni(111), using density functional theory calculations. We find stable geometries and electronic states for the nanotube on Ni(111). We propose the possibility that the C-C bonds of carbon nanotube are broken by Fe wire and Ni surface. That is, when Fe-filled SWNT(3, 3) adsorb on Ni(111) surface, SWNT transforms into arch-like structure.Comment: 13 pages, 6 figures, submitted to Japanese Journal of Applied Physics 22 April 2005. submitted to Japanese Journal of Applied Physics 22 April 200

    The Spiegelungssatz for p=5 from a Constructive Approach

    Get PDF
    We describe explicitly the relation between the 5-ranks of the ideal class groups of two quadratic fields with conductors m and 5m, respectively, and that of the associated cyclic quartic field.</p

    A patentability requirement and industries targeted by R&D

    Full text link
    In this paper, we introduce into a Schumpeterian growth model an inventive step: a minimum innovation size required for patents, which is a patentability requirement. We show that each R&D firm targets only the industries that the incumbent’s technology is sufficiently obsolete in order to satisfy an inventive step requirement. This is because a technological gap between innovator and incumbent is larger in the industries that use older technology. Under the circumstance, strengthening an inventive step requirement reduces the industries targeted by R&D, on the other hand, increases R&D investments to the targeted industries. Consequently, we find a nonmonotonic effect of the inventive step on the aggregate flow of innovations.* Revised: [14-27, 2014
