Phosphorus gradient yields threshold MAOC response governed by microbial and stoichiometric controls

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phosphorus (P) availability is a key factor that mediates the formation of mineral‐associated organic carbon (MAOC) in soils, yet reported responses to P fertilization are often inconsistent.

A multi-sensor fusion simultaneous localization and mapping algorithm suitable for coal mines

Meikuang Anquan
Simultaneous localization and mapping (SLAM) is a key technology to achieve coal mine intellectualization, but its usage is restricted in underground coal mines due to feature degradation.

Teaching socio‐communicative behaviours in play routines with caregivers: A feasibility study

British Journal of Special Education, EarlyView.
Abstract The first signs of autism often become evident as early as before a child's first birthday, and very early intervention is key to securing optimal outcomes. In the present study, two mother–child dyads participated, with mothers being trained in behavioural strategies targeting socio‐communicative behaviours in their children, who were high ...

LOFF: LiDAR and Optical Flow Fusion Odometry

Drones
Simultaneous Location and Mapping (SLAM) is a common algorithm for position estimation in GNSS-denied environments. However, the high structural consistency and low lighting conditions in tunnel environments pose challenges for traditional visual SLAM ...

The First World War at Sea: Death, Commemoration and Cultural Remembrance

History, EarlyView.
Abstract Despite the ever‐increasing body of work devoted to war memorials, national days of remembrance and the commemoration of the First World War in Britain, academic focus remains firmly on the commemoration of the First World War on land. Yet, while the number of people who died at sea paled in comparison to their counterparts on the battlefield ...

Mamba-DQN: Adaptively Tunes Visual SLAM Parameters Based on Historical Observation DQN

Applied Sciences
The parameter configuration of traditional visual SLAM algorithms usually relies on expert experience and extensive experiments, and the parameter configuration needs to be reset as the scene changes, which is a complex and tedious process.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

PEBO-SLAM: Observer Design for Visual Inertial SLAM With Convergence Guarantees

IEEE Transactions on Automatic Control
This paper introduces a new linear parameterization to the problem of visual inertial simultaneous localization and mapping (VI-SLAM) -- without any approximation -- for the case only using information from a single monocular camera and an inertial measurement unit.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

An Improved SLAM Algorithm for Substation Inspection Robots Based on 3D Lidar and Visual Information Fusion

Energies
Current substation inspection robots mainly use Lidar as a sensor for localization and map building. However, laser SLAM has the problem of localization error in scenes with similar and missing environmental structural features, and environmental maps ...
