User Equilibrium Route Assignment for Microscopic Pedestrian Simulation [PDF]

, 2014
For the simulation of pedestrians a method is introduced to find routing alternatives from any origin position to a given destination area in a given geometry composed of walking areas and obstacles. The method includes a parameter which sets a threshold

Metformin enhances external urethral sphincter integrity and restores continence via AMPK activation in a rat model of stress urinary incontinence

Animal Models and Experimental Medicine, EarlyView.
The pathogenesis of stress urinary incontinence (SUI) is intimately associated with injury to the external urethral sphincter (EUS). In this study, we established an SUI model induced by double vaginal distension and demonstrated that metformin treatment activated the AMPK signaling in the EUS tissue.

AGENT-BASED CROWD SIMULATION CONSIDERING EMOTION CONTAGION FOR EMERGENCY EVACUATION PROBLEM [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
During emergencies, emotions greatly affect human behaviour. For more realistic multi-agent systems in simulations of emergency evacuations, it is important to incorporate emotions and their effects on the agents.

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

Optimizing Evacuation Strategies in Mountain Communities to Mitigate Geohazards Risk: A Hybrid Simulation Framework

International Journal of Disaster Risk Science
Evacuation strategies play a crucial role in mitigating human casualties from geohazards. While evacuation simulations have been widely used to investigate crowd behavior in response to disasters such as fires and earthquakes, their application to ...

Robust Design Optimization for Egressing Pedestrians in Unknown Environments

, 2019
In this paper, we deal with a size-variable group of pedestrians moving in a unknown confined environment and searching for an exit. Pedestrian dynamics are simulated by means of a recently introduced microscopic (agent-based) model, characterized by an ...

3D visual simulation of individual and crowd behavior in earthquake evacuation [PDF]

SIMULATION, 2018
Simulation of behaviors in emergencies is an interesting subject that helps to understand evacuation processes and to give out warnings for contingency plans. Individual and crowd behaviors in the earthquake are different from those under normal circumstances. Panic will spread in the crowd and cause chaos.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

From individual behaviour to an evaluation of the collective evolution of crowds along footbridges

, 2016
This paper proposes a crowd dynamic macroscopic model grounded on microscopic phenomenological observations which are upscaled by means of a formal mathematical procedure.

Free Trade Zones and Corporate ESG: Evidence From a Quasi‐Natural Experiment in China

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how China's Pilot Free Trade Zones (FTZs) influence corporate ESG performance. Using a staggered difference‐in‐differences model on Chinese listed firms from 2009 to 2024, we combine coarsened exact matching (CEM) and geography‐based instrumental variables to ensure robust identification.
