Comments on correlation functions of large spin operators and null polygonal Wilson loops

We discuss the relation between correlation functions of twist-two large spin operators and expectation values of Wilson loops along light-like trajectories. After presenting some heuristic field theoretical arguments suggesting this relation, we compute the divergent part of the correlator in the limit of large 't Hooft coupling and large spins, using a semi-classical world-sheet which asymptotically looks like a GKP rotating string. We show this diverges as expected from the expectation value of a null Wilson loop, namely, as (ln mu(-2))(2). mu being a cut-off of the theory. (C) 2012 Elsevier B.V. All rights reserved.

Recomendações de usabilidade e de acessibilidade em projetos de ambientes informacionais digitais para idosos

The usability and accessibility, when applied to digital information environments, provide ease of use and access to information, respectively. Thus, we aim to discuss these concepts and apply them in specific digital environments to the elderly through the documentary and bibliographic study of specific recommendations on projects for elderly users. This study was conducted in conjunction with students at the Universidade Aberta à Terceira Idade (UNATI) - UNESP - Marilia, who assisted in the classification of recommendations for usability and accessibility are essential (Priority 1), important (Priority 2) and optional (Priority 3). The results indicate the importance of this type of study for the digital and social inclusion of older people by facilitating elements of access and use of information, providing the building more inclusive informational architectures. The resulting recommendations can be used as a starting point for the design of digital environments for the elderly in a specific heuristic evaluation, for example. However, it remains important to the application of usability testing with users, including the application to validate these recommendations, since different contexts may arise from the implementation of different elements, resources and information services.

Online Shopping Websites: An Evaluation of User Experience and Interface Ergonomic Criteria from the Perspective of Older Users

This paper presents a user experience evaluation of two online shopping websites from the perspective of older users (those aged 50 and older). Two online shopping websites were evaluated using methodological procedures established in prior research [1]. The methodology consists of four steps: (1) heuristic interface evaluation using an ergonomic criteria checklist, (2) online identification and experience questionnaire, (3) evaluation of user experience and interface interaction, and (4) satisfaction questionnaire. Results of the study revealed the analyzed websites are not suitable for older users, who find it difficult to interact with these interfaces.

Discovering promising regions to help global numerical optimization algorithms

We have developed an algorithm using a Design of Experiments technique for reduction of search-space in global optimization problems. Our approach is called Domain Optimization Algorithm. This approach can efficiently eliminate search-space regions with low probability of containing a global optimum. The Domain Optimization Algorithm approach is based on eliminating non-promising search-space regions, which are identifyed using simple models (linear) fitted to the data. Then, we run a global optimization algorithm starting its population inside the promising region. The proposed approach with this heuristic criterion of population initialization has shown relevant results for tests using hard benchmark functions.
