System Issues in Multi-agent Simulation of Large Crowds

open access: yes, 2007
Crowd simulation is a complex and challenging domain. Crowds demonstrate many complex behaviours and are consequently difficult to model for realistic simulation systems.

Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration

open access: yesAdvanced Science, EarlyView.
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

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

open access: yesInternational 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 ...

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces

open access: yesAdvanced Science, EarlyView.
The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.

Enhancing Specific Stiffness of Nano‐Architected Materials Through Generative AI and Active Learning

open access: yesAdvanced Science, EarlyView.
A structure‐centric generative framework searches voxelated design space directly, coupling a variational autoencoder with multi‐objective optimization and active learning to progressively expand the validated design domain. The discovered nano‐architectures, realized as pyrolytic carbon by two‐photon lithography, deliver 18–23% higher stiffness and 26–

A heterogeneous crowd evacuation model integrating multi-dimensional panic emotion characteristics

open access: yesJournal of Physics: Complexity
In emergency evacuation scenes, environmental uncertainties and information deficits often trigger panic among individuals, which in turn impairs their ability to make sound judgments and decisions.

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

open access: yesThe 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.

Intrinsic Mechanical Parameters and their Characterization in Solid‐State Lithium Batteries

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
This review focuses on the intrinsic mechanical parameters and their associated characterization in solid‐state batteries. The physical significance of mechanics parameters is introduced with exhaustive classifications by elastic, plastic deformations and fracture in bulk, adhesion, friction at interfaces, and mechanical fatigue in cells ...

The Effect of Selected Physical and Behavioral Factors on the Duration of Complete Crowd Evacuation in Emergencies: A Case Study of Bani Hashem Shrine [PDF]

open access: yesدانش پیشگیری و مدیریت بحران
Background and objective The primary goal in emergencies is the complete evacuation of the crowd to save lives, but the behaviors of the crowd, their interactions with the physical environment, and the use of evacuation management strategies can affect ...

Augmented reality-based evacuation simulation to study crowd behaviors [PDF]

open access: yes, 2020
To date, it has been especially challenging to correlate progress in human behavior education in emergencies with complicated dynamics of crowd behavior particularly during evacuation.
