Structures such as bridges, offshore platforms, wind power facilities, and drilling rigs generate a corresponding periodic structural response under cyclic loads such as solar radiation, tides and sea-land breeze. Data recovery and forecasting are major parts of the work to ensure structural safety using periodic structural health monitoring data. In this context, a combined method of autoregressive (AR) model and matrix factorization (MF) method is presented to reaching the tasks of data imputation and prediction. The combined method with a graph-based temporal regularizer can well capture the cyclic characteristics and random character. The verification of the method is conducted using an in-situ temperature monitoring dataset of a high-speed railway steel bridge. The application of the method for both data recovery and forecasting with structured missing entries is carried out, which indicates the combined method owns outstanding performance in accurately recover missing entries and making predictions. In the last part, the analysis of rank order and length of time lag is made to show its influence on imputation accuracy. [ABSTRACT FROM AUTHOR]

Social equity consists of opportunity equity and outcome equity. Although numerous studies have used ultimatum games to examine individuals' decision-making behavior in outcome distributions, few studies have explored this behavior in opportunity distributions. Our study used a modified version of the ultimatum game to explore fairness decision-making behavior and the underlying psychological mechanisms of opportunity equity in gain and loss contexts. We found that opportunity equity had a similar influence as outcome equity on people's fairness perception and decision-making behavior, even though the number of opportunities had nothing to do with the outcome. However, we also found that there were some differences between opportunity equity and outcome equity in the behavior pattern of evaluation and reaction processes. Our results provide evidence of inequity aversion for inequality of opportunity and expand inequity aversion theory. These findings may contribute to the reduction of social inequity and promote the development of a more harmonious society. • Opportunity equity had an impact on people's fairness perception and decision-making behavior in gain and loss contexts. • The inequity aversion in the opportunity distribution was smaller than that in the outcome distribution. • Fairness perception was affected by the fairness level of distribution, the actual self-payoff and the actual other-payoff. • The evaluation and reaction processes may be different between the opportunity equity and outcome equity.

[Display omitted] • A new phylogeny of Brisingida with broad coverage is reported. • Both Brisingida families and four genera are recovered as non-monopheletic. • Brisingida is revised to encompass 5 families and 17 genera. • New genus, species and combinations are described and a diagnostic key is provided. • Convergence caused by paedomorphosis is found in phylogenetically distant genera. Brisingida Fisher 1928 is one of the seven currently recognised starfish orders, and one of the least known taxa as being exclusive deep-sea inhabitants. Modern deep-sea expeditions revealed their common occurrences in various deep-sea settings including seamounts, basins and hydrothermal vent peripheral, underlining the necessity of clarifying their global diversity and phylogeny. In this study, we present a comprehensive molecular phylogeny of Brisingida which encompasses the highest taxonomic diversity to date. DNA sequences (COI, 16S, 12S and 28S) were obtained from 225 specimens collected in the global ocean, identified as 58 species spanning 15 of the 17 extant genera. Phylogenetic relationship was inferred using both maximum likelihood and Bayesian inference methods, revealing polyphyletic families and genera and indicating nonnegligible bias in prior morphology-based systematics. Based on the new phylogeny, a novel classification of the order, consisting of 5 families and 17 genera, is proposed. Families Odinellidae, Brisingasteridae and Novodiniidae (sensu Clark and Mah, 2001) were resurrected to encompass the genera Odinella , Brisingaster and Novodinia. Brisingidae and Freyellidae were revised to include 11 and 3 genera, respectively. A new genus and species, two new subgenera and seven new combinations are described and a key to each genus and family is provided. Transformations of morphological traits were evaluated under the present phylogenetic hypothesis. A series of paedomorphic characters were found in many genera and species, which led to a high degree of homoplasy across phylogenetically distant groups. Our results provide new insights in the phylogeny and ontogeny of the order, and highlight the necessity to evaluate character convergence under sound phylogenetic hypothesis. [ABSTRACT FROM AUTHOR]
