Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

open access: yesLaser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.

Digital surveillance of animals and nature recovery

open access: yesPeople and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Evaluation of four gridded climate products in streamflow and drought simulations in the Kelantan River Basin, Malaysia

open access: yes
The availability of meteorological stations is generally limited and sparsely dispersed in many regions. Gridded climate products (GCPs) are commonly utilized in hydro-climatic modelling due to their wide spatial and temporal coverage. This study aims to

High‐Resolution Satellite Imagery Reveals Landscape‐Scale Benthic Habitat Changes in a Turbid Coral Reef

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
High‐resolution satellite imagery and landscape metrics revealed a 77% decline in coral‐dominated habitats at Abrolhos Bank between 2010 and 2024, accompanied by macroalgal and zoanthid expansion. Spatial reorganisation indicates increasing fragmentation, homogenisation and loss of reef structural complexity.

Optimum stimulus for eliciting masseter vestibular-evoked myogenic potential: a comparative exploration with three different acoustic stimuli

open access: yesThe Egyptian Journal of Otolaryngology
Objective To compare the EMG rectified amplitude, absolute latencies, interpeak interval, and Interaural asymmetry parameters of masseter vestibular-evoked myogenic potential (mVEMP) elicited using clicks, 500 Hz tone bursts, and 500 Hz NB CE-chirps ...

Integrated assessment of meteorological drought impacts on terrestrial water storage and vegetation dynamics in East Africa

open access: yesRiver, EarlyView.
Abstract Water is essential for life, and effective hydrological management is crucial for economic stability and quality of life. Poor water resource governance can lead to scarcity, displacement, or even fatal consequences. Hydrological conditions in East Africa are influenced by drivers such as demographic expansion, industrialization, droughts, and

Managing Robot Perception: How Families Present Their Faces to a Toy Robot

open access: yesSymbolic Interaction, EarlyView.
Playing with a robot's face detection capabilities constitutes a praxeological approach to learning about new technology. We explore how family members discover suitable formations for a Cozmo robot to scan a single face, drawing on video recordings from Swedish homes. Taking an ethnomethodology and conversation‐analysis perspective, we demonstrate how

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

open access: yesBoreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Evaluating satellite rainfall products against ground-based observations over Zambia

open access: yesDiscover Geoscience
Evaluating Satellite Rainfall Products (SRPs) is essential for reliable precipitation estimates, especially in the face of climate change and inadequate networks of ground-based observations.
