The Long Trajectory of Rubber Physics: 3500+ Years and Counting

open access: yesJournal of Polymer Science, EarlyView.
Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...

WorldCuP: A database of checklists documenting the World's Cultivated Plants and their distributions

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Human life would be unrecognizable without the benefits of cultivated plants, including crops, ornamentals, or plants with other uses. Despite their importance in daily life and prevalence across landscapes, we know surprisingly little about global cultivated plant distributions.

The goals, achievements, and tools of modern geodesy

open access: yes, 2009
Friedrich Robert Helmert (1843-1917) defined geodesy as the science “of measurements and mappings of the Earth’s surface”. Over time, this definition of geodesy has been extended, mainly as a consequence of technological developments allowing geodesy to ...

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Evaluating Pose Estimation Uncertainty From Automatic Point Cloud Registration in Multi‐Sensor Robotic Systems

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The poses derived from automatic point cloud registration between stationary laser scans that occur naturally in robotic multi‐sensor systems operating in stop‐and‐go mode have the potential to greatly improve and aid localization and trajectory estimation.

Gravity changes due to mountain-building processes and their detectability with satellite gravity missions [PDF]

open access: yes, 2018
The Himalaya and Alps mountain ranges, and Tibetan plateau are presently subject to uplift, as documented by GNSS vertical movement rates. Uplift occurs in response to climatic mass loss (deglaciation or hydrologic mass loss) or due to the dynamic forces

Intrinsic Geodesy

open access: yes, 1985
The science of Geodesy has undergone far-reaching changes in the last half century. The impact of new technology, from electromag netic distance measurements to the use of artificial satellites, has been great, and is still largely to be felt.

Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

open access: yesSustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.
