Researchers develop computer model showing how diverse species can arise from arrangement of organisms across an area without physical barriers or natural selection. The study found that genetic distance increases over generations, leading to a rapid increase in species numbers until they reach a steady state.
Beijing Institute of Technology researchers developed a unique multi-living agent concept to analyze complex information systems under SRSC environment. They found that analyzing agents' livelihood can determine system behavior well or not.
Biochemist David Deamer explores the molecular self-assembly processes that led to the first protocells nearly 4 billion years ago. He proposes a combinatorial chemistry approach to understanding how life began, suggesting complex systems of molecules assembled on early Earth.
The Partition Decoupling Method (PDM) is a new mathematical tool that can unscramble the underlying structure of time-dependent, interrelated complex data. The researchers applied it to the equities market, revealing both known structures and patterns as well as new ones.
Researchers find that tree canopy-inspired branching design is more efficient than traditional models in controlling liquid flow. The study uses constructal theory to create 'smart' materials with self-healing and self-cooling properties.
The University of Washington is leading a $6.25M project to develop an electronic Sherlock Holmes system for complex data analysis in the military. The system will integrate various types of sensor data to predict behavior and make decisions, addressing the challenge of handling high degrees of complexity and uncertainty.
Researchers understand that a smooth decrease in stress at the end of a primary fault reduces the likelihood of an earthquake jumping to another fault. This study highlights the importance of slip gradient and rupture front acceleration in determining fault jump probability.
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.
