UAV‐Based Precision Seed Dropping for Automated Reforestation

Journal of Field Robotics, EarlyView.
ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Aftermath of the Forest Carbon Credit Crisis as Experienced by Restoration and Conservation Organisations

Sustainable Development, EarlyView.
ABSTRACT In 2023, The Guardian reported on several scientific studies denouncing the role of certain forest carbon credits in mitigating climate change. Subsequently, credit prices on the voluntary carbon market (VCM) plummeted—providing a quantitative indication of its impact.

Collateralization of the Body in the Central Sahara: On Forms and Effects

Economic Anthropology, EarlyView.
ABSTRACT This article tracks a transporter along the route linking Tripoli to the Saharan town of Ghadames in post‐2011 Libya, asking what secures an obligation when the institutions that normally underwrite it (offices, courts, recognized names) have receded. I distinguish the debt, the sum owed, from the security pledged to answer for it: what may be

Acoustic stimulation for sleep enhancement and declarative memory: A systematic review and meta‐analysis

Sleep Research, EarlyView.
Abstract Background Acoustic stimulation is a non‐invasive neuromodulation approach with unclear efficacy for sleep and cognition across paradigms and populations. This meta‐analysis systematically evaluated its effects on sleep architecture and declarative memory. Methods We searched the PubMed, Web of Science, the Cochrane Library, Scopus, and Embase

Self‐Assembly of a Colloidal Honeycomb Crystal in Silico for Topological Valley Photonics

Small, EarlyView.
The self‐assembly of a colloidal honeycomb crystal is demonstrated in computer simulations, using an assembly strategy that not only suppresses the formation of real‐space topological defects observed experimentally but also yields topological photonic properties in reciprocal space.

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, EarlyView.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.

Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Advanced Sensing Materials and Their Applications for Power Sensors

High Voltage, EarlyView.
ABSTRACT The construction of new‐generation power systems imposes stringent requirements on the safety and reliability of critical equipment, making accurate state perception essential for grid security and digital transformation. Sensing materials fundamentally determine sensor performance in terms of sensitivity, bandwidth, environmental adaptability
