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 ...

Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

Sensory Neuroscience, EarlyView.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

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.

The impacts of HF and VHF radiation towards preliminary breakdown events in lightning flashes

, 2019
Even though the mechanisms pertinent to the generation of radiation in frequency range above 3 MHz (HF and VHF radiation) are not well understood, it is thought that this radiation is caused by the electrical breakdown of virgin air rather than by the ...

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Investigation of preliminary breakdown pulses in lightning waveforms

, 2013
The cloud-to-ground lightning contains one or more sporadic discharges. These cloud discharges usually include a pre-starting process which is called the preliminary breakdown (PB) before a leader initiation.

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 ...

From foraging to decomposition: Large vertebrates as biotic drivers of trace element cycling across landscapes

Journal of Animal Ecology, EarlyView.
We highlight an overlooked pathway in ecosystem functioning: the role of animal carcass decomposition in trace element cycling. By linking animal life cycles to landscape‐scale processes, we explain how large animals redistribute scarce elements and influence spatial heterogeneity, with implications for ecosystem functioning and restoration.
