Research on the Audible Noise Spectrum Characteristics of Typical AC Bundled Conductors in High‐Altitude Areas at 4300 m

High Voltage, EarlyView.
ABSTRACT The low pressure in high‐altitude areas exacerbates the issue of audible noise (AN) caused by intense corona discharge on the conductor surface. This problem is a critical factor in the structural design and conductor selection for extra‐high‐voltage and ultrahigh‐voltage (UHV) AC transmission lines.

Temperature Extraction Scheme for Composite Insulator Core Rod Sheath of Overhead Transmission Lines Based on Oriented Bounding Boxes

High Voltage, EarlyView.
ABSTRACT Unmanned Aerial Vehicle (UAV) inspection of overhead transmission line composite insulators allows for the rapid acquisition of large amounts of infrared images of insulators in service, which can be used to analyse their operational status. However, efficiently and accurately analysing these images remains a challenge.

Soil N:P ratio influences species coexistence via nitrogen‐form niche differentiation in alpine grasslands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant species coexistence in nutrient‐limited ecosystems is often maintained by niche differentiation in nitrogen (N) uptake. However, how this partitioning responds to changes in nutrient stoichiometry is still poorly understood.

Dynamic rhizosphere C:N:P stoichiometry of plants, soils and microbial biomass under different grazing patterns

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Analysing grassland ecological stoichiometry is crucial for evaluating ecosystem quality and health via energy flow and elemental equilibrium. Grazing is a dominant human activity shaping alpine grasslands on the Qinghai–Tibet Plateau (QTP), yet few studies have used ...

Conservative roots confer a larger microbial carbon pump efficacy than acquisitive roots by regulating microbial life‐history strategy

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Environmental Total Factor Productivity and the Cost‐Effectiveness of GHG Emission Reduction: The Case of Crop Production in China

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT China's diversified agricultural policies have effectively improved both the yield and environmental performance of the crop sector. Quantifying productivity trends and their drivers is key to formulating strategies for high‐quality and low‐carbon crop development.

Conceptualizing moral migration: how disillusionment and the transnational right motivate migration to Russia Conceptualiser la migration morale : comment les désillusions et la droite transnationale motivent l’émigration vers la Russie

Journal of the Royal Anthropological Institute, EarlyView.
Russia is consistently a top migration destination. While most migrate to Russia from other post‐Soviet countries, a small but highly visible group of the Russian‐speaking diaspora has returned from Europe and North America. Lauded in Russian media as ‘ideological migrants’, their narratives at first glance echo those of the state as they claim to flee

Gold in Tibet

Harrison Forman wrote this article after his expeditions to Tibet in the 1930s. In 1932 Forman organized a motor caravan expedition to Central Asia and was the first Westerner to drive a motorcar to the shores of Lake Kokonor in Tibet.
