Researchers at the University of California San Diego found that oscillators operating at similar frequencies lock onto each other in succession, creating a staircase effect in the gut. This new mathematical solution answers two longstanding biological questions, shedding light on how food moves through the digestive tract and is churned.
A research team has experimentally demonstrated a nonlinear wave phenomenon that changes its frequency depending on the direction of incoming waves. The system exhibits different responses to waves entering from one side versus the other, with potential applications in medical ultrasound imaging and noise control.
Researchers developed an equation describing pressure wave propagation in bubbly flows, confirming that changes in tube cross-sectional area contribute to pressure wave attenuation. The rate of change in tube cross-sectional area is a key parameter governing pressure wave attenuation.
Researchers have experimentally confirmed complex synchronisation patterns in oscillatory systems, including leaf-like structures and gaps representing unsynchronised states. This breakthrough builds on previous studies using breathing-soliton lasers to explore nonlinear dynamics.
Researchers at Lancaster University have developed a new method to detect Alzheimer's disease by analyzing changes in brain oxygenation dynamics and neuronal function. The study found that individuals with Alzheimer's disease exhibit altered respiratory frequency, which may be an early indicator of the condition.
Scientists have successfully created conditions for mechanical qubits by engineering anharmonicity close to the ground state. By cooling a nanotube device to near absolute zero, researchers demonstrated a new mechanism that boosts nonlinear effects in the system, paving the way for quantum computing.
Researchers at Max Born Institute find that ultrafast mid-infrared excitation of electrons in bismuth reduces crystal symmetry, opening new quantum pathways for coherent phonon excitation. This leads to bidirectional atomic motions and oscillations with a frequency different from low-excitation levels.
Engineers at Tokyo Institute of Technology have developed a technique to support the classification performance of neural networks operating on sensor time series by feeding recorded signals into elementary non-linear dynamical systems. This approach increases the classification performance by augmenting the data through additional tim...
Scientists successfully created a light source that produced two entangled light beams using rubidium atoms. The entanglement was achieved by adding new detection steps to measure the quantum correlations in the amplitudes and phases of the fields generated, enabling applications in quantum computing, encryption, and metrology.
The study demonstrates that chaos synchronization can occur even under constraints of narrow frequency intervals, giving rise to phenomena that could be leveraged for useful operations in ensembles of distant nodes. This breakthrough has potential applications in distributed sensing, such as gathering readings from distant sensors.
