The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, EarlyView.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Law and Infrastructure: Reliability, Automation Transition, and Irregularities of “U‐Space”

Regulation &Governance, EarlyView.
ABSTRACT The European Union (EU) is making regulatory efforts to allow for the safe integration of drones into civilian airspace through automated means. Commission Implementing Regulation (EU) 2021/664 concerning unmanned traffic management (a system referred to as “U‐Space”) furthers that commitment. Accordingly, drone operators must avail themselves

Environment adaptive navigation (EAN): A data-driven approach for improved navigation accuracy

Mehran University Research Journal of Engineering and Technology
The quality of GNSS-based navigation services is highly influenced by the type of operating environment. The urban environments with buildings and structures pose substantial challenges for GNSS navigation accuracy. To address this challenge, we propose

Testing the Flyby Anomaly with the GNSS Constellation

, 2011
We propose the concept of a space mission to probe the so called flyby anomaly, an unexpected velocity change experienced by some deep-space probes using earth gravity assists.

GNSS Software Receiver for UAVs [PDF]

, 2016
This paper describes the current activities of GPS/GNSS Software receiver development at DTU Space. GNSS Software receivers have received a great deal of attention in the last two decades and numerous implementations have already been presented. DTU Space has just recently started development of our own GNSS software-receiver targeted for mini UAV ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

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

The 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.
