Nonlinear self-excited thermoacoustic oscillations of a ducted premixed flame: Bifurcations and routes to chaos [PDF]

, 2014
Thermoacoustic systems can oscillate self-excitedly, and often non-periodically, owing to coupling between unsteady heat release and acoustic waves. We study a slot-stabilized two-dimensional premixed flame in a duct via numerical simulations of a $G ...

Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

Sensitive and Cost‐Effective Detection of Gamma Rays Using Cd‐Functionalized QTF and MEMS–Based Microcantilever Sensors

IET Nanobiotechnology, Volume 2026, Issue 1, 2026.
Ionizing radiation poses a serious health risk to humans; therefore, sensitive detection is significant. Gamma rays are a form of ionizing radiation that can pass through the human body and interact with matter through ionization. Several techniques have been conventionally used to detect ionizing radiation.

Breath by Breath: Navigating the Landscape of Exhaled Breath in Clinical Research and Prospects for the Future

Journal of Analytical Methods in Chemistry, Volume 2026, Issue 1, 2026.
Exhaled breath analysis (EBA) has evolved as a noninvasive diagnostic technique with enormous promise in healthcare. The development in this area is based on the concept that the breathalyzers employed to measure the alcohol concentration in the blood can be utilized to evaluate health by analyzing the intricate chemical makeup of exhaled breath, which
