"Los linfocitos T son uno de los muchos tipos celulares involucrados en la respuesta inmune adaptativa. Estas células altamente móviles patrullan en busca de antígenos, alcanzan sitios de infección e infiltran tumore...

Precise temporal coordination in crowd simulation—ensuring agents arrive at targets in a specific order or at set intervals—remains a challenge for real-time applications. While existing force-based methods...

The purpose of this study is to analyze the dynamics of crowdfunding campaigns in the Middle East and raise the question of “does social capital matter” in this respect? The study uses the Zoomaal.com platform as a...

Abstract Effective evacuation strategies are critical for preventing stampedes in large-scale, high-density crowd management. This paper develops a second-order sliding mode controller within a distributed parameter syst...

Abstract As urban areas expand, the importance of crowd control and population management increases significantly. Major events are organized and structured to guarantee participant safety and mitigate disruptions and em...

"We characterize the dynamics of runners in the famous “Running of the Bulls” Festival by computing the individual and global velocities and densities, as well as the crowd pressure. In contrast with all previously s...

We present an experimental investigation of the pressure dynamics during the flow of self-propelledparticles through narrow passages. When the ensemble is flowing, pressure fluctuates around aconstant value that does not...

Dense granular flows through constrictions, as well as competitivepedestrian evacuations, are hindered by a propensity to form clogs. We use simulations of model pedestrians and experiments with granular disks to explore...

At the dawn of the twentieth century, on the platform of a southern Italian train station, amidst the bustle, women and children in tears crowd together to say goodbye to travelers. The travelers are young men who are un...

Computer simulations using Cellular Automata (CA) have been applied with considerable success in different scientific areas. In this work we use CA in order to specify and implement a simulation model that allows to inve...

We report experimental results of the speed-density relation emerging in pedestrian dynamics when individuals keep a prescribed safety distance among them. To this end, we characterize the movement of a group of people r...

It is suggested that the motion of pedestrians can be described as if they would be subject to ``social forces.'' These ``forces'' are not directly exerted by the pedestrians' personal environment, but they are a measure...

Since the 1938 United States Fair Labor Standards Act, the classification of work days and rest days has become fundamental in urban studies. However, identified distinctive mobility patterns challenge this framework, ex...
