Ghrist's technique involves replacing a complex physical system with an abstract space for easier analysis. He can then use algebra and calculus to break down the abstract space into pieces, figure out their structure, and reassemble them to gain insight into the physical system.
The National Institute of Standards and Technology (NIST) has developed a program to facilitate the development and sharing of security configuration checklists. The program provides guidelines for creating more effective checklists and includes an easy-to-use repository of existing checklists.
A new quantum computer architecture, proposed by NIST scientist Emanuel Knill, overcomes the fragility of qubits by using a pyramid-style hierarchy and teleportation to continuously double-check accuracy. This approach enables reliable computing even if individual logic operations make errors up to 3 percent of the time.
A UCLA physicist uses complex systems analysis to study how best-selling books reach their sales peaks, finding that two types of shocks can lead to predictable sales patterns. The researcher's model has been applied to understanding earthquakes and other natural disasters.
A new study by Northwestern University researchers shows that social networks can efficiently lead to global organization, even with imperfect information transmission due to noise or error. The model is adaptable and robust, capable of responding to external conditions, and people tend to adjust their opinions based on the majority
Dr. Hou's project aims to develop a theoretical foundation for wireless sensor network design and deployment, focusing on optimal routing, performance limits, and energy-related problems. The goal is to fill gaps in current understanding and enable the growing field of wireless sensor networks to realize its potential.
Researchers have developed a new method to find communities in large, complex networks, revealing structure and commonalities among members. The technique was tested on college football conferences with over 90% accuracy, showing promise for understanding systems like food webs and social networks.
A University of Toronto study examines the 2000 Walkerton and 2001 North Battleford water contamination outbreaks, blaming systemic failures on human factors. The research highlights the importance of information circulation, competence, and public safety guidelines in complex systems.
A team of researchers has discovered that using small-world networking can improve the efficiency of parallel computing in simulations. By linking computers to their nearest neighbors and a few other random computers, the simulation process can run faster without data traffic jams.
Annualised hours contracts (AHCs) offer advantages for both companies and staff, including higher hourly wages, lower overtime, and stronger job security. AHCs are often implemented in volatile industries with complex shift systems, providing employees with flexibility over the working year.
A cognitive psychologist at Brookhaven Lab provides guidance on designing voting systems that minimize human error and facilitate accurate understanding. The expert's recommendations include organizing information in a consistent manner, providing clear instructions, and allowing voters to control the pace of their use.
Researchers at TSRI develop a method for controlling chemical reactions by encapsulating molecules in nanocapsules, enabling self-regulatory amplification and exponential growth. This discovery offers a new approach to controlling reactivity without the need for autocatalysts.
