Epidemiological studies have identified associations between mortality and changes in concentration of particulate matter. These studies have highlighted the public concerns about health effects of particulate air pollution. Modeling fine particulate matter PM2.5 exposure risk and monitoring day-to-day changes in PM2.5 concentration is a critical step for understanding the pollution problem and...
objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...
Objective: The effects of scoliotic deformity on the biomechanics of gait are not clear. The aim of this study was to compare the spatiotemporal variables during gait in adolescent idiopathic scoliosis and healthy individuals. Methods: Eighteen healthy adolescent girls and 19 adolescent patients with idiopathic scoliosis that were matched for age, height, mass and BMI participated in this stud...
conclusions zebris movement analysis system is a highly reliable instrument for the measurement of gait parameters at different speeds in healthy athletes and those after acl reconstruction surgery. this implies its use in the assessment and treatment process of gait deficits in such a clinically important population. background reconstruction surgery is one of the treatment methods after an an...
The influence of partial coupling delay on the spatiotemporal spiking dynamics is explored in a modular neuronal network. The modular neuronal network is composed of two subnetworks which present the small-world property and scale-free property, respectively. Numerical results show that spatiotemporal order that the modular network is most coherent in time and nearly synchronized in space can e...
Detection of motion is a crucial component of visual processing. To probe the computations underlying motion perception, we created a new class of non-Fourier motion stimuli, characterized by their third- and fourth-order spatiotemporal correlations. As with other non-Fourier stimuli, they lack second-order correlations, and therefore their motion cannot be detected by standard Fourier mechanis...
Species diversity in nature is accomplished by coexistence. In a spatial environment, inferior but rapidly moving species can coexist with superior but relatively stationary species. Recent work showed that chaotic dynamics can provide the spatiotemporal variation in the fitness required for coexistence, via the dynamical mechanism of synchronization and intermittency. Utilizing a realistic mod...

background: patellofemoral pain syndrome (pfps) is one of the most frequent causes of anterior knee pain in adolescents and adults. this disorder can have a big effect on patients’ ability and quality of life and gait. methods: this review included all articles published during 1990 to 2016. an extensive literature search was performed in databases of science direct, google scholar, pubmed an...
The Spatio-temporal data is the description of the time, space, and attribute information of the geographic spatiotemporal process, which reflects the spatio-temporal process information of geographical phenomenon changing with the time on the earth-surface space. The spatio-temporal process information is complex and changing. Thus according to the objective of dynamic visualization of geograp...
