Integrated sediment mapping and evaluation in riverbed considering fluvial geomorphic diversity

Frontiers in Remote Sensing
A crucial indicator of hydrodynamic conditions, sediment transport systems, and geomorphic evolution is riverbed sediment. Hydraulic engineering, channel upkeep, and ecological management all depend on accurate sediment classification.

Borophene‐based sensing platforms: Pioneering ultrasensitive detection

FlexMat, EarlyView.
Schematic Diagram of Performance Optimization Strategies and Sensing Application Characteristics of Two‐Dimensional Boron‐Based Materials in Novel Sensors. Abstract Borophene is an emerging two‐dimensional (2D) material. Since significant breakthroughs were achieved in the experimental synthesis of borophene, the exploration and development of ...

Tidal bore effect in heavy ion collisions [PDF]

Journal de Physique Lettres, 1976
Between the very high energy regime (E > 200 MeV/N) where the energy deposited by the projectile into the target nucleus propagates behind the incoming particle at the velocity of sound and the low energy regime ( E < 40 MeV/N) where partial equilibrium might be reached, we predict the appearance of a new class of phenomena.

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

Sentipensar [Feel‐Thinking] Cultivates Collective Scientific Sensemaking and Worldbuilding Within and Beyond Ecological Despair

Science Education, EarlyView.
ABSTRACT Educating youth about environmental and climate justice is crucial in realizing a sustainable and flourishing future. Yet this can be challenging given the intense eco‐emotions youth experience and express while learning about these consequential realities and their implications.

Developing a low‐cost drone‐based method for deploying and retrieving autonomous recording units in inaccessible areas

Wildlife Society Bulletin, EarlyView.
Autonomous recording units (ARUs) are increasingly used for passive acoustic monitoring, but deploying them in remote or inaccessible locations remains challenging. We developed and field‐tested a lightweight, low‐cost floating platform for drone‐assisted deployment and retrieval of ARUs in wetland interiors.

Impact of and adaptation strategies for sea-level rise on Yangtze River Delta

Advances in Climate Change Research, 2018
The Yangtze River Delta characterized by a dense population and a rapidly developing economy is highly vulnerable to sea-level rise. The data from the China Oceanic Information Network and the Zhejiang Provincial Hydrology Bureau are used to analyze sea ...

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

Minimal analytical model for undular tidal bore profile; quantum and Hawking effect analogies

New Journal of Physics, 2018
Waves travelling up-river, driven by high tides, often consist of a smooth front followed by a series of undulations. A simple approximate theory gives the rigidly travelling profile of such ‘undular hydraulic jumps’, up to scaling, as the integral of ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.
