Automated extraction of leaf mass per area from digitized herbarium specimens
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Physical Modeling of Current-Induced Seabed Scour around a Vibrating Submarine Pipeline
Most of the existing researches either focus on vortex-induced-vibrations (VIV) of a pipeline near a rigid boundary, or on seabed scour around a fixed pipeline. In the fields, pipeline vibration and seabed scour are actually always coupled.

Novel Glomeromycotina–moss associations identified in California dryland biocrusts
Summary Drylands, which comprise c. 45% of Earth's land area, host biological soil crusts (biocrusts): symbiotic communities of cyanobacteria, fungi, algae, lichen, and bryophytes that stabilize soil and support key ecosystem functions. Moss‐dominated biocrusts are particularly interesting due to their potential to illuminate ancient bryophyte–fungal ...

Pipelines placed on the seabed are subjected to a range of hydrodynamic forces due to currents, waves and tidal events.The seabed is often disturbed by the complex flowconditions so that sediment transport and erosion can be caused.

Numerical simulations are conducted to investigate the local scour below a vertically vibrating subsea pipeline for gap ratios ranging from −0.3 to 0.1 and a wide range of reduced velocities ranging from 0.5 to 15.

Experimental Study on the Function of Spoilers in Protecting Submarine Pipeline
:A new method was proposed to protect submarine pipelines. Flexible spoilers were installed under the submarine pipeline to change the flow field and pressure distribution, and reduce the pressure gradient between both sides of the pipeline, so that to ...

Safety Assessment of Gas Pipelines Crossing River through Hydrodynamic Analysis
Gas pipelines are buried and installed across rivers to supply the gas necessary for daily life. When crossing rivers, gas pipelines are typically installed on bridges; however, when installation on bridges is not feasible, the pipelines are buried in ...

Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

Experimental study of scour around a forced vibrating pipeline in quiescent water
Submarine pipelines are widely used for the conveyance of hydrocarbons, oil or other fluids in the offshore industry. Although much progress has been made on pipeline-seabed interactions in the past decades, an experimental study solely devoted to ...
