Animal Development: Crowd Control
نویسنده
چکیده
To shape a developing animal, individual cell movements must be coordinated over long distances. Two recent studies help show how this is achieved during convergence and extension of the Drosophila germ-band, where polarity within the plane of the embryonic epithelium biases junction remodeling to polarize cell intercalation.

Parietal neural prosthetic control of a computer cursor in a graphical-user-interface task.
OBJECTIVE To date, the majority of Brain-Machine Interfaces have been used to perform simple tasks with sequences of individual targets in otherwise blank environments. In this study we developed a more practical and clinically relevant task that approximated modern computers and graphical user interfaces (GUIs). This task could be problematic given the known sensitivity of areas typically used...
متن کاملA Federated Agent-based Crowd Simulation Architecture
Crowd control has become increasingly important in urbanized military operations such as peace keeping, riot control, disaster management, emergency evacuation, and rescue operations. In this paper, we describe an architecture for simulating virtual crowd to aid in the training, planning and decision making process in the area of military operations. Our system makes use of the light-weight age...
متن کاملCrowd Simulation Via Multi-Agent Reinforcement Learning
Artificial intelligence is frequently used to control virtual characters in movies and games. When these characters appear in crowds, controlling them is called crowd simulation. In this paper, I suggest that crowd simulation could be accomplished by multi-agent reinforcement learning, a method by which groups of agents can learn to act autonomously in their environment. I present a case study ...
متن کاملA Conceptual Framework for Investigating Organizational Control and Resistance in Crowd-Based Platforms
This paper presents a research agenda for crowd behavior research by drawing from the organizational control literature. It addresses the need for research into the organizational and social structures that guide user behavior and contributions in crowd-based platforms. Crowd behavior is situated within a conceptual framework of organizational control. This framework helps scholars more fully a...
متن کاملAnimal Disease and the Industrialization of Agriculture
The industrialization of animal agriculture has fundamentally transformed animal health markets while animal health innovations have promoted this industrialization. The subtlety of these interactions shows how little we know about agricultural industrialization. To illustrate, we consider three stylized features of industrialized animal agriculture. These are the closing off of production acti...
