Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search

Journal of Field Robotics, EarlyView.
ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

Radio galaxies and their environment [PDF]

, 1993
The relationships between radio galaxies and their environment are varied, complex, and evolve with cosmic epoch. Basic questions are what role the environment plays in triggering and fuelling (radio) galaxy activity what the effects of this activity are on its environment, and how radio galaxies and environment evolve. Clearly, this could be the topic

Innovation for Sustainable Development: Assessing Sustainability‐Oriented Innovations in the UK Palm Oil Supply Chains

Sustainable Development, EarlyView.
ABSTRACT This research evaluates the adoption of Sustainability‐Oriented Innovations (SOIs) by UK food manufacturers, particularly in the palm oil sector. Despite the global palm oil industry's environmental and social impacts, such as deforestation and labour exploitation, empirical studies on SOIs are limited. This paper addressed this gap by mapping

Environment of Quiescent Low-mass Galaxies Hosting AGNs in MaNGA

The Astrophysical Journal
The discovery of active galactic nuclei (AGNs) in low-mass ( M _* ≤ 5 × 10 ^9 M _⊙ ) galaxies has pushed forward the idea that AGN feedback may play a role in quenching star formation in the low-mass regime.

From voids to filaments: environmental transformations of galaxies in the SDSS

, 2017
We investigate the impact of filament and void environments on galaxies, looking for residual effects beyond the known relations with environment density. We quantified the host environment of galaxies as the distance to the spine of the nearest filament,

High‐Contrast Colorless‐to‐Colored Thermochromic Materials

Small, EarlyView.
We developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated

Adsorption of Helium on Cationic or Anionic Tetracene and Pentacene

Small Structures, EarlyView.
How does the arrangement of helium atoms that are adsorbed on tetracene or pentacene ions change with increasing coverage? When does the adsorption layer change from 1D to 2D, and to 3D? Is the transition abrupt? Are the helium atoms localized? Is the arrangement the same for cations and anions? What changes as the acene grows in length?

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.
