A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

open access: yesIbis, EarlyView.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.

Impacts of land use change on diaspore‐dispersing ant assemblages in southwestern Amazonia

open access: yesInsect Conservation and Diversity, EarlyView.
Land use changes shift ant assemblages, more intensive land uses are dominated by generalist and open habitat specialist species engaging in group foraging. The diaspore removal rates cannot differ, but the quality of dispersal was lower in disturbed habitats.

Integrative Computational and Experimental Approaches Reveal the Protective Role of Moderate Caffeine Intake Against Apical Periodontitis Induced Bone Loss

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To investigate whether moderate systemic caffeine intake modulates the progression of apical periodontitis (AP) and associated alveolar bone loss, combining in vivo rat experiments with in silico molecular docking to explore potential mechanisms. Methodology Male Wistar rats were randomly assigned to four groups (n = 8 per group): control,

Navigating the Tension Lines of Value Co‐Creation: Frontline Care Staff's Experiences With Residential Transition Processes for Service Users in Co‐Located Supported Housing

open access: yesSocial Policy &Administration, EarlyView.
ABSTRACT Theoretically grounded in Public Service Logic (PSL), this study investigates frontline care staff's experiences with value‐creation negotiations across residential transition processes for service users with intellectual disabilities to and within co‐located supported housing in a Norwegian municipal setting.

Estimating Mangrove Forest Volume Using Terrestrial Laser Scanning and UAV-Derived Structure-from-Motion

open access: yesDrones, 2019
Mangroves provide a variety of ecosystem services, which can be related to their structural complexity and ability to store carbon in the above ground biomass (AGB).

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

Studying the influence of livestock pressure on gully erosion in rangelands of SW Spain by means of the UAV+SfM workflow

open access: yesBoletín de la Asociación de Geógrafos Españoles, 2018
Gully erosion in agrosilvopastoral systems of SW Spain represents a common degradation process, but has been hardly analysed. The suitability of using the Unmanned Aerial Vehicles (UAV) and Structure from Motion photogrammetry (SfM) workflow to map ...

On computing local monodromy and the numerical local irreducible decomposition

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

Fusion of dense spatial features and sparse temporal features for three‐dimensional structure estimation in urban scenes

open access: yesIET Computer Vision, 2013
The authors present a novel approach to improve three‐dimensional (3D) structure estimation from an image stream in urban scenes. The authors consider a particular setup, where the camera is installed on a moving vehicle.
