    Comparison of adaptive optical scanning holography based on new evaluation methods

    Abstract Adaptive Optical Scanning Holography (AOSH) represents a powerful technique that employs an adaptive approach to selectively omit certain lines within holograms, guided by the utilization of Normalized-Mean-Error (NME) as a predictive measure. This approach effectively diminishes scanning time and conserves the storage space required for data preservation. However, there exists alternative methods superior to…

  • Protective effect of uridine on atrial fibrillation: a Mendelian randomisation study

    Protective effect of uridine on atrial fibrillation: a Mendelian randomisation study

    Abstract Uridine, a pyrimidine nucleoside, is crucial in the synthesis of metabolites. According to observational studies, a higher plasma uridine level is associated with a lower risk of atrial fibrillation (AF). However, the casual relationship between uridine and AF is still unknown. In this study, we used the Mendelian randomisation (MR) approach to explore causality.…

    Carbon footprint and embodied nutrition evaluation of 388 recipes

    Abstract Food consumption, which delivers fundamental energy and essential nutrients to human beings, is crucial for achieving a series of sustainable goals. Alongside rising population growth and living standards, there has been a significant increase in food cultivation demands, supply chain complexities, and waste management. Therefore, to protect human health and the environment, promoting sustainable…

    Spring biomass burning in Indochina enhances summer Yangtze River Valley rainfall through land–atmosphere interactions

    Abstract Indochina is one of the regions with the most severe biomass burning (BB) in the world, which produces enormous amounts of atmospheric aerosols, mostly in spring. Moreover, the spring soil moisture anomalies in Indochina have been found to have a significant influence on the summer rainfall in the Yangtze River Valley (YRV). It is…

Usually they request a set of drawings, she says, with a detailed set of requirements. But Smith, who joined London’s Royal Botanic Gardens, Kew, more than 20 years ago, says: “We also…

  • Local Bayesian Dirichlet mixing of imperfect models

    Local Bayesian Dirichlet mixing of imperfect models

    Abstract To improve the predictability of complex computational models in the experimentally-unknown domains, we propose a Bayesian statistical machine learning framework utilizing the Dirichlet distribution that combines results of several imperfect models. This framework can be viewed as an extension of Bayesian stacking. To illustrate the method, we study the ability of Bayesian model averaging…

  • Influence of forest vegetation restoration on carbon increment after mining

    Influence of forest vegetation restoration on carbon increment after mining

    Abstract We have clarified the study area has a history of 65 years and has been restored for 6 years. This study investigated the carbon storage characteristics of undisturbed natural forests and restored mining vegetation in Yunnan Province, China. The goal was to quantify carbon reserves and increments to inform ecological restoration strategies. Four vegetation components (tree,…

  • Earth just had its hottest year on record — climate change is to blame

    Earth just had its hottest year on record — climate change is to blame

    The past 12 months were the hottest on record. Some 7.3 billion people worldwide were exposed, for at least 10 days, to temperatures that were heavily influenced by global warming, with one-quarter of people facing dangerous levels of extreme heat over the past 12 months, according to a report by the non-profit organization Climate Central.…

  • Why is Delhi’s air pollution so bad right now?

    Why is Delhi’s air pollution so bad right now?

    As the Hindu festival of Diwali kicks off on 10 November, the Indian capital of Delhi, already blanketed in choking smog, is bracing for pollution to worsen. Over the past week, children struggling to breath the acrid air have flooded hospital emergency departments, and schools have been forced to close. Why is Delhi’s air pollution…
