State‐Dependent Market (In)Efficiency in Cryptocurrency Markets

Journal of Futures Markets, EarlyView.
ABSTRACT This paper develops a meta‐learning framework to test whether cryptocurrency market inefficiency is static or state‐dependent. To resolve competing claims between the Efficient and Adaptive Market Hypotheses (AMH), we construct an adaptive trading strategy using high‐frequency data for 50 major cryptocurrencies.

Fractal dimensions of fractal transformations and quantization dimensions for bi-Lipschitz mappings

Journal of Fractal Geometry, Mathematics of Fractals and Related Topics
In this paper, we study the fractal dimension of the graph of a fractal transformation and also determine the quantization dimension of a probability measure supported on the graph of the fractal transformation. Moreover, we estimate the quantization dimension of the invariant measure corresponding to a weighted iterated function system consisting of ...

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.

Analysis of Impact Crushing Characteristics of Steel Fiber Reinforced Recycled Aggregate Concrete Based on Fractal Theory

Fractal and Fractional
The fractal theory can effectively describe the complexity and multi-scale of concrete under impact load and provide a scientific basis for evaluating concrete’s impact resistance.

Fractal dimension

, 1995
The role of Fractal Geometry as an extension of Classical Geometry has become increasingly important, making it now possible to define shapes of clouds, coastlines and profiles in the horizon.

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 ...

The Fractal Dimension of Taxonomic Systems

, 1990
The hypothesis that biological diversity has a fractal geometry is tested through the examination of size-frequency distributions of taxa with different numbers of subtaxa. Data used derive from 44 checklists and catalogues of species concerning protists,

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Linking Ecosystem Risk, Health, Services to Ecological Security Assessment in the Yellow River Basin: Spatiotemporal Dynamics and Nonlinear Driving Characteristics

Land Degradation &Development, EarlyView.
ABSTRACT A scientific assessment of ecological security (ES) and its nonlinear mechanism for key driving factors in the Yellow River Basin (YRB) is of great significance for ecological protection and sustainable development. This study proposes an ES assessment framework, which links ecosystem risk (ER), ecosystem health (EH), and ecosystem services ...
