One of the main tasks in analyzing pedestrian movement is to detect places where pedestrians stop, as those places usually are associated with specific human activities, and they can allow us to understand pedestrian movement behavior. Very few approaches have been proposed to detect the locations of stops in positioning data sets, and they often are based on selecting the location of candidate stops as well as potential spatial and temporal thresholds according to different application requirements. However, these approaches are not suitable for analyzing the slow movement of pedestrians where the inaccuracy of a nondifferential global positioning system commonly used for movement tracking is so significant that it can hinder the selection of adequate thresholds. In this article, we propose an exploratory statistical approach to detect patterns of movement suspension using a local indicator of spatial association (LISA) in a vector space representation. Two different positioning data sets are used to evaluate our approach in terms of exploring movement suspension patterns that can be related to different landscapes: players of an urban outdoor mobile game and visitors of a natural park. The results of both experiments show that patterns of movement suspension were located at places such as checkpoints in the game and different attractions and facilities in the park. Based on these results, we conclude that using LISA is a reliable approach for exploring movement suspension patterns that represent the places where the movement of pedestrians is temporally suspended by physical restrictions (e.g., checkpoints of a mobile game and the route choosing points of a park).

A coarse-grained model of a two-dimensional colloidal suspension was designed. The model was athermal and, in addition, a lattice approximation was introduced. It consisted of solvent (monomer) molecules, dimer molecules, and immobile impenetrable obstacles that introduced additional heterogeneity into the system.

Quercetin is a natural flavonoid and one of the most powerful antioxidants. Due to its wide range of biological properties, it may improve cognitive and physical performance by affecting nervous tissue. The current study is aimed at determining the effect of prenatal exposure to quercetin against methimazole (MMI)-induced hypothyroidism on reflexive motor behavior in mouse offspring.

Schizophrenia is an esteemed neuropsychiatric condition delineated by the manifestation which role of the N-methyl-D-aspartate receptor (NMDAR) is important. Lutein administration exhibits protective effects via NMDA receptors. Thus, the main goal of this research was to investigate how lutein can possibly act as an antioxidant and provide protection for the brain against schizophrenia-like behaviours in mice.

Objectives: This research aims to investigate the relationship between the height of the internal longitudinal arch of the foot and the static and dynamic balance of 7-10-year-old boy gymnasts.
Methods: This study was descriptive-correlational, and its statistical population included male gymnast students aged 7 to 10 in the city of Gouchan. These gymnasts were screened for flat feet using the Brady test.

Background: Mesenchymal stem cells may have neuroprotective and tissue regenerative capabilities and the potential to rescue retinal degeneration in chorioretinal diseases including myopic chorioretinal atrophy. Transplantation of human (allogeneic) adipose tissue-derived mesenchymal stem cell (adMSC) suspensions has been clinically conducted to treat retinal degenerative diseases. However, serious side effects including proliferative vitreoretinopathy and epiretinal membrane formation have been reported.
