Review: Fractal Geometry in Precipitation

open access: yesAtmosphere
Rainfall, or more generally the precipitation process (flux), is a clear example of chaotic variables resulting from a highly nonlinear dynamical system, the atmosphere, which is represented by a set of physical equations such as the Navier–Stokes ...

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

open access: yesDeep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Stretch Tunable Active Frequency Selective Fabric for Dynamically Switchable Bandstop and Transparency

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This stretchable active frequency selective fabric achieves reversible switching between bandstop and transparent states through strain‐induced reconfiguration of its conductive network. Its zero‐power and mechanically tunable characteristics offer potential for wearable electromagnetic functional materials.

An algorithm for seizure detection in rodents

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Epilepsy animal research often relies on long‐term intracranial electroencephalographic (iEEG) recordings. Here, we describe an artificial neural network (ANN) algorithm for automatic detection of seizures. Methods The algorithm was trained on iEEG recordings of three mouse models of chronic epilepsy: (1) the pilocarpine model of ...

Fractal Geometry on Hyperbolic Manifolds

open access: yes, 2006
In this survey we give a report on some recent results obtained in the studies of hyperbolic manifolds by means of fractal geometry. Emphasis has been put on results derived in the quantitative and qualitative fractal analysis of long term geodesic dynamics on hyperbolic manifolds.
