Responsive liquid metal materials towards unstructured environment

Responsive Materials, Volume 4, Issue 1, February 2026.
Room‐temperature liquid metals integrate conductivity, deformability, and interfacial dynamics, enabling robust performance in unstructured environments. This review highlights key properties, requirements, and applications across in vivo, underwater, natural, space, and radiation settings, with advances in sensing, actuation, thermal regulation, and ...

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 ...

Experimental and theoretical investigation of the flashback of a swirling, bluff-body stabilised, premixed flame [PDF]

, 2015
Flashback of an open turbulent, premixed flame in a swirl burner with central bluff-body is considered. The aim is to obtain further understanding of the physical mechanisms responsible for the upstream flame propagation.

Focused Power Ultrasound Mediated Inferior Perirenal Adipose Tissue Modification Therapy for Essential Hypertension: A Pilot Study

The Journal of Clinical Hypertension, Volume 27, Issue 10, October 2025.
ABSTRACT Perirenal adipose tissue (PRAT) contributes to the maintenance of elevated blood pressure through afferent nerves and serves as an important peripheral, modifiable target for hypertension management. This single‐center, prospective pilot trial assessed the feasibility and safety of a novel focused power ultrasound device for perirenal adipose ...

Detached Eddy Simulation (DES) of a Turbulent Premixed Flame Stabilized on a Bluff Body

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 2, June 2025.
ABSTRACT As the demand for net‐zero emissions intensifies, low‐emission fuels (LEFs) are increasingly explored for their potential to reduce pollutants in combustion systems. The present study investigates the flame dynamics and pollutant emissions (CO and NOx) of different LEFs using detached eddy simulations (DES), a method that offers better ...

Weakly nonlinear analysis of thermoacoustic bifurcations in the Rijke tube [PDF]

, 2016
In this study we present a theoretical weakly nonlinear framework for the prediction of thermoacoustic oscillations close to Hopf bifurcations. We demonstrate the method for a thermoacoustic network that describes the dynamics of an electrically heated ...
