The United States is the world's largest oil/gas methane emitter according to current national reports. Reducing these emissions a top priority in US government's climate action plan. Here, we use 2010 2019 high-resolution inversion of surface and satellite observations atmospheric quantify emission trends for individual production regions North America relate them infrastructure. We estimate mean 14.8 (12.4 16.5) Tg a-1 2019, 70% higher than reported by Environmental Protection Agency....
The Pacific oyster, Crassostrea gigas, belongs to one of the most species-rich phyla and provides important ecological economical services. Here we present a genome assembly for variety this species, black-shelled using combination 61.8 Gb Nanopore long reads 105.6 raw BGI-seq short reads. comprised 3,676 contigs, with total length 587 Mb contig N50 581 kb. Annotation identified 283 (48.32%) repetitive sequences 26,811 protein-coding genes. A long-term transposable element active,...
Resource depletion, land-use change, and population growth triggered by the industrial revolution represent serious issues shared globally that have altered structure, processes, functions of ecosystems had significant impacts on human well-being survival security. This paper assesses changes in ecosystem service values (ESVs) karst areas based perspective change. Guizhou province, which is typical South China Karst (SCK) ecologically fragile areas, was taken as a research subject. The past,...
Forest fires, severe natural disasters causing substantial damage, necessitate accurate predictive modeling to guide preventative measures effectively. This study introduces an enhanced window-based Transformer time series forecasting model aimed at improving the precision of forest fire predictions. Leveraging data from 2020 2021 in Chongli, a myriad influencing factors were ascertained using remote sensing satellite and GIS technologies, with their interrelationships estimated through...
In supply chain research, it is essential to consider factors related carbon emissions due global climate change. this paper, we examine a dual-channel green consisting of one manufacturer leader and retailer follower where there are direct channel channel, formulating the corresponding centralized decentralized model Compared with single-channel chain, at disadvantage existence channel. A promotion policy, as kind common activity in operation proposed make more competitive, performance...
This paper presents a novel sizing and optimization approach for the emerging series-hybrid unmanned convertiplane, which can be used to translate top-level design requirements into parameters corresponding optimal power supply strategy minimum total takeoff weight. The method comprehensively considers constraints in rotor, fixed-wing, transition modes, pays special attention characteristic response of Series Hybrid Electric System (S-HES) complex application scenarios, especially coupling...
The rocky desertification control project in karst areas exacerbates the transfer of landscape types, changes ecosystem structure and function, has a significant impact on ecological assets. How to analyze relationship between type shifts spatial temporal evolution assets is one key questions that need be addressed achieve goal overall improvement quality sustainable regional economic development. This study takes Qixingguan District, Bijie City, Guizhou Province—a typical plateau...
Hybrid electric distributed propulsion tilt-wing UAVs show unlimited application prospects due to their high efficiency and vertical take-off landing capabilities. Aiming at the power requirements of UAVs, this article presents an optimization design method for series hybrid systems suitable type aircraft. Based on flight conditions constraints various modes, demand models are established mode, transition forward mode. The solving each component system by analyzing architecture transmission...
The joined-wing configuration SensorCraft, presents a more feasible way to meet tough design requirements such as long- endurance and 360-deg radar coverage compared conventional flying wing configurations. Proper assessment of the interactions between aerodynamics, structure, embedded antenna in optimization SensorCraft is essential obtain superior performances. This paper establishes performance estimation model describes an integrated process aerodynamic, aircraft. Results show that...
The unmanned tilt-wing cargo aircraft using distributed propulsors is an emerging significantly different from traditional types. This paper proposes aerodynamic, propulsion, noise, weight integrated optimization design method for this new aircraft. consists of several functional modules specially developed or adjusted targeting the aircraft's characteristics, such as boundary state analysis, propeller/rotor oblique inflow waked wing noise evaluation, multi-state mass multi-objective genetic...
Introduction In aquatic animals, colors not only reflect their sensory qualities but also affect nutritional components and market price. Noble scallop Chlamys nobilis is an importantly economical bivalve cultured in the south sea of China renowned for its various shell colors. Methods this study, nutrient compositions were compared among golden, yellow, brown colour noble scallops originating from same population breeding new varieties. Results Among three scallops, there no significant...
The Nanwenghe Nature Reserve is located in the Daxing’anling forest region, which abundant meadow resource prone to fire season every year. In this paper, change soil chemical properties of burned stands was emphasized. results showed that: (1) Soil organic matter (SOM) concentration an extremely significant difference from that control (p < 0.01). Alkali-hydrolysable N, available K and total N were significantly lower than those 0.05). (2) Total P, K, pH P not different concentrations...
Abstract Wildfire, as a natural phenomenon, shapes global ecosystems and threatens human communities. The meteorological conditions of the forest environment is one critical factors, which exists obvious effect on risk wildfire for given landscape fuel type. It high challenge to predict wildland fire risks owing huge amount paramenters with volume,variety,value velocity. Driven by emerging Artificial Intelligence Big Data analytics, this work proposes machine learning model (Fuzzy C-Means...
