Spiking neural networks (SNNs) serve as a promising computational framework for integrating insights from the brain into artificial intelligence (AI). Existing software infrastructures based on SNNs exclusively support simulation or brain-inspired AI, but not both simultaneously. To decode nature of biological and create we present cognitive engine (BrainCog). This SNN-based platform provides essential infrastructure developing AI simulation. BrainCog integrates different neurons, encoding...
Abstract The optical properties of atmospheric secondary brown carbon (BrC) aerosol are poorly understood because its chemical complexity, and this has hampered quantitative assessments the impacts light‐absorbing material on glaciers Tibetan Plateau. For study, a statistical approach was developed to investigate BrC light absorption over southeastern margin Secondary sources for were more important than primary ones. A diurnal cycle in explained by formation chromophores photochemical...
The light-absorbing properties of atmospheric brown carbon (BrC) are poorly understood due to its complex chemical composition. Here, a black-carbon-tracer method was coupled with source apportionments organic aerosol (OA) explore the primary and secondary BrC from North China Plain (NCP). Primary emissions contributed more OA light absorption than processes, biomass burning accounted for 60% at λ = 370 nm, followed by coal combustion (35%) hydrocarbon-like (5%). Secondary high in early...
Urban fugitive dust samples were collected to determine the chemical profiles of over Xi'an. Seventy eight and divided into categories paved road dust, construction cement soil dust. Eighteen elements, including Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Ba, Pb, water–soluble inorganic ions, Na+, Mg2−, Ca2−, NH4−, F−, Cl−, NO3− SO42−, measured. The most abundant elements in these urban Fe. Ti showed strong positive correlations with each other, indicating they are typical...
Heihe River Basin is the second largest inland river basin in China, where water supply service upper reach has greater influence on sustainable development of middle and lower reaches. This study analyzed land use/land cover change (LUCC) by carrying out scenario simulation. Firstly, we LUCC climate during 1990–2005; then service, which was represented annual yield, estimated with Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model. Thereafter three scenarios (precipitation...
Abstract. Brown carbon (BrC) constitutes a large fraction of organic and exhibits strong light absorption properties, thus affecting the global radiation budget. In this study, we investigated chemical functional bonds, sources BrC in six megacities China, namely Beijing, Harbin, Xi'an, Chengdu, Guangzhou, Wuhan. The average values coefficient mass efficiency at 365 nm northern cities were higher than those southern by 2.5 1.8 times, respectively, demonstrating abundance present China's...
Abstract Realistic projection of future climate‐carbon (C) cycle feedbacks requires better understanding and an improved representation the C in permafrost regions current generation Earth system models. Here we evaluated 10 terrestrial ecosystem models for their estimates net primary productivity (NPP) responses to historical climate change Northern Hemisphere. In comparison with satellite estimate from Moderate Resolution Imaging Spectroradiometer (MODIS; 246 ± 6 g m −2 yr −1 ), most...
This study investigates the impact of spatial changes over a 400-year period on summer microclimate residential courtyard in China. Using ENVI-met simulations, we analyze how factors such as orientation, building height, and opening positions affect thermal environment. The results show that east–west-oriented courtyards experienced 0.2–0.4 °C lower daytime temperatures compared to north–south ones. Additionally, taller surrounding buildings increased courtyard’s average temperature by...
Abstract Cirque metrics are widely used to deduce palaeoclimate conditions, with extensive research in the alpine regions of High Mountain Asia (HMA). Some debates remain regarding relationship between cirque morphology and climate/topography a detailed study is needed deepen knowledge development. This delineated analysed 375 cirques eastern Kunlun Mountains, northeastern Tibetan Plateau. Results show that area development degree decrease from west east. Cirques modern glaciers...
The timing and extent of ‘Little Ice Age’ (LIA) glacial advances on the Tibetan Plateau (TP) are critical for understanding climate during past millennium. However, lack LIA chronologies in central Tibet makes it difficult to fully understand nature throughout TP. In this study, two presumed moraines east Mount Jaggang, Xainza range, TP, were examined dated using 10 Be surface exposure dating. Eight boulders from yielded apparent exposure-ages ranging 41 ± 31 529 130 years. These indicate...
Mountain glaciers are sensitive to climate change, especially in climatic transition zones. We investigated Late Quaternary glacial history two valleys around the Karola Pass of eastern Lhagoi Kangri Range, central Himalaya, using cosmogenic 10Be surface exposure dating. Four events were dated 0.36 ± 0.09 0.13 0.02 ka (LIA = Little Ice Age), 2.5 0.2 (Neoglacial), 9.7 0.4 8.2 (Early Holocene) and 23.1 0.9 16.3 0.7 (LGM-LG, LGM Last Glacial Maximum; LG Lateglacial). The extent glacier coverage...
