Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Dynamic Winkler Foundation for vibration analyses of flexible footings
Procedia Engineering, 2017 Abstract For the design of mitigation measures against railway traffic induced vibrations the interaction between the unbounded soil and the flexibility of the foundation must be taken into account. Common numerical schemes like Boundary Elements, Transmitting Boundaries, and Perfectly Matched Layer bear computational costs which render their ...

Analytic Study on Rigid Beam Resting on Winkler Foundation
Journal of the Korea Academia-Industrial cooperation Society, 2011 Displacement, contact pressure and moment which are developed in rigid beam on the Winkler foundation and 2 parameter Winkler foundation were derived. It can be seen that moment distribution along with rigid beam on the Winkler foundation are regardless of spring constant and the moments calculated from assuming linear spring constant were greater than

Characterization of spin-orbit interactions of GaAs heavy holes using a quantum point contact
, 2014 We present transport experiments performed in high quality quantum point contacts embedded in a GaAs two-dimensional hole gas. The strong spin-orbit interaction results in peculiar transport phenomena, including the previously observed anisotropic Zeeman
