    Completeness Rules for Spin Observables in Pseudoscalar Meson Photoproduction

    The number and type of measurements needed to ascertain the amplitudes for pseudoscalar meson photoproduction are analyzed in this paper. It is found that 8 carefully selected measurements can determine the four transversity amplitudes without discrete ambiguities. That number of measurements is one less than previously believed. We approach this problem in two distinct ways: (1) solving for the amplitude magnitudes and phases directly; and (2) using a bilinear helicity product formulation to map an algebra of measurements over to the well-known algebra of the 4Ă—44\times 4 Gamma matrices. It is shown that the latter method leads to an alternate proof that 8 carefully chosen experiments suffice for determining the transversity amplitudes completely. In addition, Fierz transformations of the Gamma matrices are used to develop useful linear and nonlinear relationships between the spin observables. These relationships not only help in finding complete sets of experiments, but also yield important constraints between the 16 observables for this reaction.Comment: 32 pages, no figures, LaTeX/REVTeX, submitted to Phys.

    One-China Policy and Taiwan

    In April 2003, the severe acute respiratory syndrome ( SARS ) disease spread to the island of Taiwan. These statements, made by the general who assigned the R.O.C. government to assume the task of the post-surrender administration of Formosa, and those of the high governmental officials of the leading Allied Powers not only demonstrate that the R.O.C. government has not acquired title to the island of Taiwan by occupation for the State of China, but also attest to the existence of a rule in international law that if title to a territory of the defeated State is to be changed after a war, then it must be achieved by a territorial treaty. ... Because the modern State is based on territory, China\u27s claim of sovereignty over Taiwan is necessarily predicated on its claim of title to the island of Taiwan. As analyzed herein, China never reacquired title to the island of Taiwan by any recognized means in international law: it did not acquire it under the Cairo Declaration; it did not acquire it by the Peace Treaty of San Francisco or any other treaty

    The Exact Wavefunction Factorization of a Vibronic Coupling System

    We investigate the exact wavefunction as a single product of electronic and nuclear wavefunction for a model conical intersection system. Exact factorized spiky potentials and nodeless nuclear wavefunctions are found. The exact factorized potential preserves the symmetry breaking effect when the coupling mode is present. Additionally the nodeless wavefunctions are found to be closely related to the adiabatic nuclear eigenfunctions. This phenomenon holds even for the regime where the non-adiabatic coupling is relevant, and sheds light on the relation between the exact wavefunction factorization and the adiabatic approximation

    Multi-Label Zero-Shot Learning with Structured Knowledge Graphs

    Full text link
    In this paper, we propose a novel deep learning architecture for multi-label zero-shot learning (ML-ZSL), which is able to predict multiple unseen class labels for each input instance. Inspired by the way humans utilize semantic knowledge between objects of interests, we propose a framework that incorporates knowledge graphs for describing the relationships between multiple labels. Our model learns an information propagation mechanism from the semantic label space, which can be applied to model the interdependencies between seen and unseen class labels. With such investigation of structured knowledge graphs for visual reasoning, we show that our model can be applied for solving multi-label classification and ML-ZSL tasks. Compared to state-of-the-art approaches, comparable or improved performances can be achieved by our method.Comment: CVPR 201

    Implement Innovative Proactive-Service-Center to Enhance Service Performance in Customer Site

    Get PDF
    How to more efficiently and effectively enhance service performance is an on-going challenge to any service team. A new service model, Proactive-Service-Center (P-S-C), is developed since Feb’01. As a result, the service performance results are improved in terms of same day issue closure rate, issue response time and system uptime. The P-S-C is not only an innovative way to enhance service performance but also a systematic way to build-up engineers\u27 trouble-shooting capability. In the old service situation, the information flows randomly among customer engineers, customer section managers, AMT engineers, and AMT site managers. The average time spent is around two hours from Issue Happened to Dedicated Engineer on site. Customer and AMT engineers are running around like a chicken without head. The information flows inefficiently and ineffectively among customer engineers, section managers, AMT engineers and site managers. The detailed solutions are not documented and remained in the engineers\u27 heads. In the PSC model, the information flows automatically from the system which is down to the customer Server then to the PSC Server and the dedicated AMT engineer is automatically informed. The information flows efficiently and effectively. The actions done are then systematically entered and documented in PSC and a monthly analysis report is generated and provided to customers. The cost savings of PSC can be estimated indirectly. The issue response time is reduced from 2 hours to 58 minutes (reduced by 62 minutes). This translates to the increase of system uptime by 62 minutes. This will bring cost savings. In addition, the issue closure rate is improved from 50% to 85% (improved by 35%). This also translates to the increase of system uptime. The system uptime enhancement is cost savings. Three areas which need improvement are identified to be Technology, People and Process. Technology: Internet is used and many auto functions (for example, reminding, reporting) are built-in to enhance the capability. People: Dedicated Engineer Matrix is built-in PSC and the right engineer can be reached at the right time in the most efficient manner. Process: Process is real time and systematic with clear R&R defined to ensure efficiency and experience build-up in the future
