The Crustal Thickness of the Philippine Sea Plate Derived from Gravity Data

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
We constructed a new free-air gravity anomaly map of the Philippine Sea Plate (PSP) using ship-tracked gravity data from the National Geophysical Data Center (NGDC).

Transition from connected to fragmented vegetation across an environmental gradient: scaling laws in ecotone geometry [PDF]

open access: yes, 2009
A change in the environmental conditions across space—for example, altitude or latitude—can cause significant changes in the density of a vegetation type and, consequently, in spatial connectivity.

Exogenous stimulation of Tanacetum vulgare roots with pipecolic acid leads to tissue-specific responses in terpenoid composition. [PDF]

open access: yesPlant Biol (Stuttg)
Tissue‐specific changes in terpenoid patterns in tansy are induced by simulated induction of systemic acquired resistance using pipercolic acid. Abstract Tanacetum vulgare L., tansy, is a perennial plant with highly variable terpenoid composition, with mono‐ and sesquiterpenoids being the most abundant.

Challenges facing green space: is statute the answer? [PDF]

open access: yes, 2019
Against a backdrop of austerity, characterised by public-sector funding cuts and a devolutionary agenda, this paper explores how legislation might address two, inter-related challenges which face public urban green space ('greenspace') in England and ...

A numerical method for efficient 3D inversions using Richards equation

open access: yes, 2017
Fluid flow in the vadose zone is governed by Richards equation; it is parameterized by hydraulic conductivity, which is a nonlinear function of pressure head.

Determining the prevalence and predictors of sleep disordered breathing in patients with chronic heart failure: rationale and design of the SCHLA-HF registry [PDF]

open access: yes, 2014
BACKGROUND: The objective of the SCHLA-HF registry is to investigate the prevalence of sleep-disordered breathing (SDB) in patients with chronic heart failure with reduced left ventricular systolic function (HF-REF) and to determine predictors of SDB in ...

Determining Geological Properties by a Hybrid Seismic-Magnetotelluric Approach [PDF]

open access: yes, 2002
This paper concerns the controlled source audio magnetotelluric technique (CSAMT) for imaging subsurface structure. Given the short time available, we limited our investigation to a simple 1D earth model where regional seismic and well logs suggest ...

High‐Precision Delineation of Curie Point Depth Under Remanent Magnetization Using Physics‐Informed Neural Networks

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Curie point depth (CPD), a key indicator of the lithosphere's thermal structure, is typically estimated using spectral analysis or interface inversion methods. However, these approaches often neglect the effects of remanent magnetization, leading to substantial uncertainty.

Successful Implementation of Environmental Policy and Governance: Understanding and Modeling Micro Governance

open access: yesEnvironmental Policy and Governance, Volume 36, Issue 2, Page 221-239, April 2026.
ABSTRACT Successful implementation of environmental policy and governance highly depends on the capacity to know about, build new and utilize existing governance structures. However, the theoretical tools and available methods to assess the complexity of emerging or existing structures are rather limited.
