Coherence‐Gated Wrapped‐Phase InSAR With Matrix‐Based Uncertainty Diagnostics for Burial‐Mound Hotspot Ranking (Sicily, Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

Defect‐Engineered SrTiO3‐x for Flexoelectric‐Dominated Catalysis

open access: yesEcoEnergy, EarlyView.
Defect‐engineered SrTiO3‐x nanoparticles with enhanced flexoelectricity efficiently degrade pollutants and produce hydrogen under ultrasound‐driven flexocatalysis. This materials–engineering approach offers a scalable pathway for combining environmental remediation and renewable energy applications. ABSTRACT Flexocatalysis provides an alternative route

Straightening out planar poly-line drawings [PDF]

open access: yes, 2014
We show that any $y$-monotone poly-line drawing can be straightened out while maintaining $y$-coordinates and height. The width may increase much, but we also show that on some graphs exponential width is required if we do not want to increase the height.

Solar Geoengineering Effects on Malaria Transmission Risk in South Asia Under G6sulfur Scenario

open access: yesInternational Journal of Climatology, EarlyView.
Comparison of EIR (unit: No of infected bites per person per day) for each considered country in South Asia, under the considered scenarios, averaged over the period 2020–2090. A regression equation is shown for each country (for Bhutan EIRG = 0.1690 × 10−10 EIRS + 0.5968 × 10−12) to illustrate the projected trend.

Modem illumination of monotone polygons

open access: yes, 2009
We study a generalization of the classical problem of illumination of polygons. Instead of modeling a light source we model a wireless device whose radio signal can penetrate a given number k of walls. We call these objects k-modems and study the minimum number of k-modems necessary to illuminate monotone and monotone orthogonal polygons.

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Marine litter can shift sea turtle nests toward the shoreline

open access: yesOikos, EarlyView.
Marine litter is an emerging threat to sea turtle rookeries, yet its effects on nesting behaviour remain poorly understood. In this study, we investigated how macro‐litter accumulation on beaches influences the spatial distribution of loggerhead turtle Caretta caretta nests on Boa Vista Island, Cabo Verde.

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

Numerical Methods for Solving Convection-Diffusion Problems [PDF]

open access: yes, 2012
Convection-diffusion equations provide the basis for describing heat and mass transfer phenomena as well as processes of continuum mechanics. To handle flows in porous media, the fundamental issue is to model correctly the convective transport of ...
