RefGPT: Reference -> Truthful & Customized Dialogues Generation by GPTs and for GPTs
General chat models, like ChatGPT, have attained impressive capability to
resolve a wide range of NLP tasks by tuning Large Language Models (LLMs) with
high-quality instruction data. However, collecting human-written high-quality
data, especially multi-turn dialogues, is expensive and unattainable for most
people. Though previous studies have used powerful LLMs to generate the
dialogues automatically, but they all suffer from generating untruthful
dialogues because of the LLMs hallucination. Therefore, we propose a method
called RefGPT to generate enormous truthful and customized dialogues without
worrying about factual errors caused by the model hallucination. RefGPT solves
the model hallucination in dialogue generation by restricting the LLMs to
leverage the given reference instead of reciting their own knowledge to
generate dialogues. Additionally, RefGPT adds detailed controls on every
utterances to enable highly customization capability, which previous studies
have ignored. On the basis of RefGPT, we also propose two high-quality dialogue
datasets generated by GPT-4, namely RefGPT-Fact and RefGPT-Code. RefGPT-Fact is
100k multi-turn dialogue datasets based on factual knowledge and RefGPT-Code is
76k multi-turn dialogue dataset covering a wide range of coding scenarios. Our
code and datasets are released in https://github.com/ziliwangnlp/RefGP
Seroprevalence Survey of Avian influenza A (H5) in wild migratory birds in Yunnan Province, Southwestern China
BACKGROUND: Highly pathogenic avian influenza virus (HPAIV) is a highly contagious disease which is a zoonotic pathogen of significant economic and public health concern. The outbreaks caused by HPAIV H5N1 of Asian origin have caused animal and human disease and mortality in several countries of Southeast Asia, such as Bangladesh, Cambodia, China, India, Indonesia, Laos, Myanmar, Thailand and Viet Nam. For the first time since 1961, this HPAIV has also caused extensive mortality in wild birds and has sparked debate of the role wild birds have played in the spread of this virus. Other than confirmed mortality events, little is known of this virus in wild birds. There is no report on the seroprevalence of avian influenza H5 infection in wild migratory birds in Yunnan Province. In this study we examined live wild birds in Yunnan Province for H5 specific antibody to better understand the occurrence of this disease in free living birds. METHODS: Sera from 440 wild birds were collected from in Kunming and Northern Ailaoshan of Yunnan Province, Southwestern China, and assayed for H5 antibodies using the hemagglutination inhibition (HI) assays. RESULTS: The investigation revealed that the seroprevalence of avian influenza H5 was as following: Ciconiiformes 2.6%, Strigiformes 13.04%, Passeriformes 20%, Cuculiformes 21.74%, Gruiformes 0%, Columbiformes 0%, Charadriiformes 0% and Coraciiformes 0%. Statistical analyses showed that there was a significant difference of prevalence between the orders (P < 0.01). Specific avian influenza H5 antibodies were detected in 23 of 440 (5.23%) sera. Mean HI titer 23 positive sera against H5 were 5.4 log(2). CONCLUSIONS: The results of the present survey indicated that the proportion of wild birds had previously infected AIV H5 at other times of the year. To our knowledge, this is the first seroprevalence report of avian influenza H5 infection in wild migratory birds in China’ s southwestern Yunnan Province. The results of the present survey have significant public health concerns

Comparative analysis between the laser beam welding and low current pulsed GMA assisted high-power laser welding by numerical simulation
By introducing the low current pulsed gas metal arc (GMA), the bridging ability of the laser beam welding (LBW) can be effectively improved. However, the impact mechanism of the additive GMA is hard to investigate by experimental methods. In this paper, the three-dimensional transient mass and heat transfer models of the low current pulsed GMA assisted high-power laser welding and single LBW are established. The pulsed arc and laser heat source models are optimized based on the arc morphology images, arc voltage and welding current. The drop transfer and arc pressure models are improved by comprehensively considering the effect of the molten pool surface deformation and the interaction of laser and arc on the arc heat flow distribution. Based on the established welding models, a comparative analysis is conducted to investigate the evolution characteristics of the temperature and flow fields in the molten pool. The simulated results show that the additive low current pulsed GMA in novel hybrid welding significantly increases the high temperature region of the molten pool, while allowing the liquid metal to expand transversely, thereby increasing the length and width of the molten pool. These greatly improve the bridging ability of LBW and extend its application range

Analyzing Macro-Level Ecological Change and Micro-Level Farmer Behavior in Manas River Basin, China
Environmental degradation is closely related to unreasonable land use behaviors by farmers. In this study, participatory rural assessment (PRA) is used to conduct a detailed survey of farmers and plots and to collect relevant natural and social statistics. The accuracy of remote sensing data is verified by comparative analysis, and the change in status of various land use types in each research period is reflected by the change in the dynamic degree and change in range. We examine how farmers’ attitudes and behaviors affect environmental degradation, using a sample of 403 farmers in China’s Manas River Basin. Due to age, education, income and other differences, farmers’ land use behaviors, as well as their attitude toward and feelings about environmental degradation, vary greatly. We found that most farmers considered the environment to be very important to their lives and crop production, but nearly 21% did not know the causes of environmental degradation and nearly 8% did not consider the environmental impacts of their crop production activities. A new model for oasis expansion—land integration—is presented here. This model can increase the area of cultivated land, reduce cultivated land fragmentation, save irrigation water, improve the field microclimate and form a good ecological cycle. Through land transfer, ecological compensation and ecological protection incentives, the government should guide farmers’ land use behaviors toward cooperation with the river basin’s ecological protection and land use planning
Analysis of Ecological and Economic Benefits of Rural Land Integration in the Manas River Basin Oasis
Land consolidation is an effective means of promoting the regularization of fragmented arable land, optimizing the allocation of land resources and improving the environment in farming areas, as well as an important means of increasing the economic returns of farming households, and it is important to scientifically assess the ecological and economic benefits of agricultural land consolidation. In this study, participatory rural assessment (PRA) was used to investigate, in detail, the meaning, satisfaction and changes in farmland rehabilitation before and after implementation. The accuracy of the remote sensing data was verified through an experiment on the net cultivation coefficient. We used a sample of 447 farmers from nine villages in Manas County to study the differences in plot area, crop unit value, income and irrigation before and after the farmers’ integration. We found that, after the integration of farmland, the cultivated area increased significantly, the crop unit yield increased by at least 42.66%, the average income of farmers increased by a value of RMB 4324/ha and the water savings were all higher than 7.18 m3/ha. At the same time, after the integration of farmland, the number of plots was significantly reduced, the arable land became more regular and the microclimate of the farmland improved significantly. The government and individuals should follow the concept and construction requirements of the “community of life in mountain, water, forest, lake, grass and sand”, consider the economic and ecological benefits of land consolidation, ensure the quality of farmland ecosystems, actively explore new models of land consolidation and stimulate the economic vitality of rural areas
