Fractal Geometry as an Effective Heat Sink

Strojniški vestnik - Journal of Mechanical Engineering, 2022
"How long is the coast of Britain?" was the question stated by Mandelbrot. Using smaller and smaller rulers the coast length limits to infinity. If this logic is applied to the fractal heat sink geometry, infinite cooling capacity should be obtained using fractals with mathematically infinite surface area.

Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Wearable acoustic bioelectronics for health monitoring and therapy

FlexMat, EarlyView.
Wearable acoustic bioelectronics (WABEs) enable flexible, integrated, wireless, and miniaturized platforms for ultrasound‐based monitoring and therapeutic modulation. Abstract Wearable acoustic bioelectronics (WABEs) are an emerging class of body‐coupled acoustic systems that integrate ultrasound transducers with miniaturized electronics, spanning skin‐

Simultaneous 3/4‐power scaling of leaf mass and 2/3‐power scaling of leaf area with stem mass in plants

Grassland Research, EarlyView.
Abstract Background Plant allometry theory developed in the last century focused on 2/3‐power scaling, determined by light interception considerations. More recently, 3/4‐power scaling based on the properties of vascular distribution networks has been proposed.

Temperature–strain decoupled electronic skin for human–machine interaction

InfoMat, EarlyView.
Temperature fluctuations can cause signal drift in wearable strain sensors, interfering with human‐motion monitoring. This study integrates a serpentine strain sensor with a miniature thermistor and uses a temperature–strain calibration model to compensate for temperature‐induced resistance changes in real time, suppressing thermal drift while ...

Multi‐Objective Spatial Optimization of Cropland Layouts in Highly Urbanized Regions: Evidence From Dongguan, China

Land Degradation &Development, EarlyView.
ABSTRACT Cropland protection in highly urbanized regions requires reconciling stable quantitative‐qualitative targets with the functional optimization of extremely fragmented spatial structures. This study develops a patch‐level multi‐objective spatial reconfiguration framework of cropland layouts based on the Non‐dominated Sorting Genetic Algorithm‐II

Hyperbolic Laplacian and Dirichlet Problem in the Bicomplex Context

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this article, we present all the necessary elements for the detailed solutions of the Dirichlet problem for the cases of the 𝔹ℂ–unit disk and for what we will call the semi–positive subspace in 𝔹ℂ (which is the analogous of the half right–side space in complex analysis).

Inferring Inter‐Well Fracture Interactions in Unconventional Reservoirs Using Fiber‐Optic Sensing and Coupled Multiphysics Modelling

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Integrating distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) data with numerical simulations to analyze inter‐well interference and production responses remains challenging. This study employs a coupled thermal–hydraulic–mechanical simulation framework to model heat transfer, fluid flow, and geomechanical responses ...
