A transition from asymmetric to symmetric patterns in time-dependent extended systems is described. It is found that one dimensional cellular automata, started from fully random initial conditions, can be forced to evolve into complex symmetrical patterns by stochastically coupling a proportion p of pairs of sites located at equal distance from the center of the lattice. A nontrivial critical v...
A motion trajectory is an intuitive representation form in time-space domain for a micromotion behavior of moving target. Trajectory analysis is an important approach to recognize abnormal behaviors of moving targets. Against the complexity of vehicle trajectories, this paper first proposed a trajectory pattern learning method based on dynamic time warping (DTW) and spectral clustering. It intr...
betes mellitus and pulmonary tuberculosis has long been observed. Moreover, the incidence of tuberculosis in diabetics is more than in the general population. Windle,' in a study of 333 necropsies of diabetics, gave an incidence of pulmonary tuberculosis in 50 per cent. Himsworth' reported an incidence of 6.5 per cent pulmonary tuberculosis in routine x-ray films. Root3 stated that in children ...
Given a multimillion-node social network, how can we summarize connectivity pattern from the data, and how can we find unexpected user behavior? In this paper we study a complete graph from a large who-follows-whom network and spot lockstep behavior that large groups of followers connect to the same groups of followees. Our first contribution is that we study strange patterns on the adjacency m...
As one of the motivational theories which define both values and attitudes beyond personal as well as organizational benefits, Public Service Motivation (PSM) model aims to underscore the appreciation of individuals with regard to public interests. If PSM pattern being optional is synchronized with civic-organizational behavior, its effectiveness is manifested in improving service quality. The ...
BACKGROUND Idiopathic REM sleep behavior disorder is a prodromal stage of Parkinson's disease and dementia with Lewy bodies. Hyposmia, reduced dopamine transporter binding, and expression of the brain metabolic PD-related pattern were each associated with increased risk of conversion to PD. The objective of this study was to study the relationship between the PD-related pattern, dopamine transp...
Due to the lack of access to the real-world event-log repositories in critical domains such as healthcare and banking, the evaluation and maintenance of data analytics algorithms has become a challenge. Generating synthetic log repositories that simulate a variety of complex real-world event-log repositories will be an effective way of producing benchmarks to evaluate data analytics algorithms ...
Property classifications and patterns, i.e., high-level abstractions that describe common behavior, have been used to assist practitioners in generating formal specifications that can be used in formal verification techniques. The Specification Pattern System (SPS) provides descriptions of a collection of patterns. Each pattern is associated with a scope that defines the extent of program execu...
We report the generation of a dynamic labyrinthine pattern in an active alcohol film. A dynamic labyrinthine pattern is formed along the contact line of air/pentanol/aqueous three phases. The contact line shows a clear time-dependent change with regard to both perimeter and area of a domain. An autocorrelation analysis of time development of the dynamics of the perimeter and area revealed a str...
