UAV Remote Sensing Inversion of Pond Water Depth Based on Color-Space Conversion

Redai dili
Shore-based ponds are small water bodies widely distributed in coastal areas and play important roles in aquaculture, agricultural irrigation, and ecological regulation. Accurate and efficient water-depth monitoring is key to the scientific management of

Focal Mechanism and Rupture Process of 2004 Alhoceima (Morocco, Mw=6.2) Earthquake from Teleseismic and Regional Broad-Band Data. [PDF]

, 2004
We have study the focal mechanism of the 2004 Alhoceima (Morocco, Mw=6.2) earthquake using teleseismic and regional broad-band data. The solution obtained shows strike slip motion with planes striking respectively on NNE-SSW and WNW-ESE direction and ...

Mapping Nanoscale Protein‐Corona Kinetics of DoE‐Optimized Perfluorocarbon Encapsulated‐PLGA Nanoparticles by In Situ, Time‐Resolved Synchrotron SAXS

Advanced Healthcare Materials, EarlyView.
A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

First detection of the ground state JK = 1 sub 0 going to 0 sub 0 submillimeter transition of interstellar ammonia [PDF]

The JK = 1 sub 0 approaching O sub 0 transition of ammonia at 572.5 GHz was detected in OMC-1 from NASA's Kuiper Airborne Observatory. The central velocity of the line (VLSR approximately = 9 km/s) indicates that it originates in the molecular cloud ...

Bifunctional Surfaces With Immobilized Antibodies and Bioactive Peptides Mediate Selective Capture and Proliferation of Endothelial Colony‐Forming Cells

Advanced Healthcare Materials, EarlyView.
A tunable bifunctional surface is developed by combining Fc‐binding peptides and RGD motifs to present oriented antibodies alongside integrin‐mediated signaling. The platform selectively captures endothelial colony‐forming cells while promoting their adhesion and proliferation.

A Wavelet Extraction Method of Attenuation Media for Direct Acoustic Impedance Inversion in Depth Domain

Applied Sciences
The seismic image produced by pre-stack depth migration is more accurate and has clearer geological significance than the time image. However, the waveform of the depth-domain seismic image is affected not only by depth-dependent velocity variation but ...

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

Joint inversion of Rayleigh wave phase velocity and ellipticity using USArray: Constraining velocity and density structure in the upper crust [PDF]

, 2012
Rayleigh wave ellipticity, or H/V ratio, observed on the surface is particularly sensitive to shallow earth structure. In this study, we jointly invert measurements of Rayleigh wave H/V ratio and phase velocity between 24–100 and 8–100 sec period ...

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.
