A new computational model analyzes any type of complex network, revealing critical points for controlling the entire system. Researchers found sparse networks require more nodes to control, while dense networks need fewer. The algorithm offers potential applications in reprogramming adult cells and identifying new drug targets.
New research from Psychological Science shows that attentional task sets modulate subliminal semantic and visuomotor processes differently. High-capacity individuals recover more quickly from distractions than low-capacity individuals.
Researchers at EPFL developed a brain-computer interface that learns to recognize users' mental intentions, allowing for multitasking and reducing fatigue. The system uses statistical analysis and probability theory to distinguish between commands and enable users to control devices over longer periods.
The DFG will establish 11 new Collaborative Research Centres, receiving €94.4m for four-year projects on astrophysics, immune systems, and data analysis. New CRCs focus on efficient lift systems, self-organisation in physics & biology.
Researchers developed a special sequence of high-precision electromagnetic pulses to protect the arbitrary quantum state of a single spin. This breakthrough enables the use of nitrogen-vacancy centers in diamond as highly sensitive nanoscale magnetic sensors and potentially, qubits for larger-scale quantum information processing.
Professor John A. Burns received the W. T. and Idalia Reid Prize for his work in computational methods for control, design, and optimization of infinite dimensional dynamical systems. The prize is funded by an endowment from the late Mrs. Idalia Reid.
A new device developed at the Weizmann Institute uses sniffing technology to enable communication and wheelchair steering for severely disabled individuals. The device was tested on healthy volunteers and quadriplegics, showing promising results in mastering the skill, which can also be used as a 'third hand' for surgeons and pilots.
Researchers at Cornell University have developed a method to precisely study electron interactions using single-molecule devices. By controlling the spin of cobalt-based molecules, they observed how it affects electron flow and interaction with surrounding conduction electrons.
John A. Burns has been awarded the W. T. and Idelia Reid Prize in Mathematics for his fundamental contributions to computational methods and applications in control, design, and optimization of infinite dimensional dynamical systems. He is currently working on reducing energy consumption and greenhouse gas emissions through modeling, s...
A study published in the Journal of Vision found that outfielders catch fly balls by tracking optical acceleration, rather than predicting the ball's trajectory. The research used a virtual environment to test three major theories of fly catching, and confirmed that baseball players continuously track the ball and run forward or backwa...
Rafal Goebel, an Assistant Professor at Loyola University Chicago, will be honored with the SIAM Activity Group on Control and Systems Theory Prize for his contributions to hybrid systems and control theory. The prize recognizes his novel results on well-posedness of solutions and robustness of asymptotic stability in hybrid control sy...
Scientists discovered that atomic nuclei in NMR experiments behave according to super-adiabaticity, a quantum mechanical concept. This can help improve image resolution and potentially lead to portable MRI machines.
A study by Adam Galinsky and Jennifer Whitson found that individuals seek to regain control by perceiving connections between unrelated events, leading to superstitions and conspiratorial thinking. Restoring a sense of control can normalize perceptions and behavior.
The study, which examined men's reports of sexual desire and arousal, found that factors like depression, relationships, and scent play a significant role in shaping their experiences. The Kinsey Institute's dual control model suggests that separate systems for excitation and inhibition exist within the central nervous system.
Researchers at Kennedy Krieger Institute discovered separate adaptable networks controlling each leg and leg movements, e.g., forward or backward walking. This finding enhances understanding of motor skills and brain plasticity, signaling advancements for future rehab practices.
Murat Arcak, a researcher at Rensselaer Polytechnic Institute, received the 2007 SIAG/CST Prize for his work on passivity approach and robustness in largescale networks. His research has enhanced performance and robustness for wireless and biological networks.
Researchers have developed a novel simulator that can recreate quantum behavior in atoms and particles, enabling control over individual parts of a quantum system. This breakthrough is crucial for developing powerful quantum computers that can perform calculations billions of times faster than normal computers.
The USC-Harvard team identified a protein switch that regulates the immune response, shedding light on the balance between tolerance and aggression in autoimmune diseases. The finding supports the combinatorial control theory of gene expression, with implications for understanding signal transduction and transcriptional networks.
A software suite will be developed to simulate and calculate chemical properties, enabling the control of complex chemical processes in Navy's all-electric ships. The partnership combines advances in molecular theories, computer algorithms, and supercomputing capabilities.
