Abstract:
... The temporal variation of greenhouse gas concentrations in China during the COVID-19 lockdown in China is analyzed in this work using high resolution measurements of near surface △CO₂, △CH₄ and △CO concentrations above the background conditions at Lin'an station (LAN), a regional background station in the Yangtze River Delta region. During the pre-lockdown observational period (IOP-1), both △CO₂ a ...
temporalvariation, etc ; crop residues; cropland; China; Show all 4 Subjects
Abstract:
... Burning crop residues is a common way to remove them during the final stages of crop ripening in China. To conduct research effectively, it is critical to reliably and quantitatively estimate the extent and location of a burned area. Here, we investigated three publicly available burned area products—MCD64A1, FireCCI 5.1, and the Copernicus Burnt Area—and evaluated their relative performance at es ...

Abstract:
... Mesial temporal lobe epilepsy (MTLE) is the most common partial complex epilepsy in adults and the most unresponsive to medications. Electrical deep brain stimulation (DBS) of the hippocampus has proved effective in controlling seizures in epileptic rodents and in drug-refractory MTLE patients. However, current DBS paradigms implement arbitrary fixed-frequency or patterned stimuli, disregarding th ...

Abstract:
... Approaching to groundwater management means of controlling multiple pollutants from multiple sources, with high spatial and temporal variability. This complex socio-ecological issue cannot be solved only by scientific knowledge developed in controlled research settings. The challenge lies on different forms of analysis that consider the interdependencies and uncertainties of the real world, adding ...
temporalvariation, etc ; Japan; atmospheric deposition; environment; uranium; Show all 5 Subjects
Abstract:
... We examine the temporal changes of ²³⁶U/²³⁸U and ²³⁵U/²³⁸U in atmospheric deposition from samples collected in Tokyo and Akita from 1963 to 1979 and elucidate the spatial distribution and historical changes of the anthropogenic sources of uranium in Japan. The ²³⁶U/²³⁸U ratio of atmospheric deposition in Tokyo peaked in 1963 and again during the 1970s, while the corresponding ²³⁵U/²³⁸U ratios of a ...

Abstract:
... Citizen science offers a unique opportunity to connect urban-dwellers with the often hidden natural world upon their doorsteps and to contribute to authentic research that increases knowledge of urban ecology and biodiversity. With the majority of Australia’s population residing in large cities, this diverse potential pool of participants in science creates a significant opportunity to increase th ...

Abstract:
... Recent research related to the evolution of different types of green water events, generated in wave flume experiments, has shown that some events, such as plunging-dam-break (PDB) and hammer-fist (HF) types, can present multiple-valued water surface elevations during formation at the bow of the structure. However, the applicability of analytical models to capture the evolution (i.e., the spatio-t ...

Abstract:
... Smart control in water systems aims to reduce the cost of infrastructure expansion by better utilizing the available capacity through real-time control. The recent availability of sensors and advanced data processing is expected to transform the view of water system operators, increasing the need for deploying a new generation of data-driven control solutions. To that end, this paper proposes a da ...

Abstract:
... Three Gorges Reservoir area, the largest reservoir area in China The frequency and intensity of extreme weather events increase with climate warming, and the local climate effects in the large reservoir area may also change the local precipitation structure. Therefore, based on the precipitation sequence data in the Three Gorges Reservoir (TGR) area from 1959 to 2019, the proposed multi-time-scale ...

Abstract:
... Amidst the global extinction crisis, climate change will expose ecosystems to more frequent and intense extreme climatic events, such as heatwaves. Yet, whether predator species loss—a prevailing characteristic of the extinction crisis—will exacerbate the ecological consequences of extreme climatic events remains largely unknown. Here, we show that the loss of predator species can interact with he ...

Abstract:
... Quantifying the uncertainty linked to the degree to which the spatio‐temporal variability of the catchment descriptors (CDs), and consequently calibration parameters (CPs), represented in the distributed hydrology models and its impacts on the simulation of flooding events is the main objective of this paper. Here, we introduce a methodology based on ensemble approach principles to characterize th ...

Abstract:
... Individual variation is central to species involved in complex interactions with others in an ecological system. Such ecological systems could exhibit tipping points in response to changes in the environment, consequently leading to abrupt transitions to alternative, often less desirable states. However, little is known about how individual trait variation could influence the timing and occurrence ...

Abstract:
... Phytoplankton assemblages are privileged descriptors of the ecological status of marine ecosystems regularly included in routine monitoring programmes. The high spatial and temporal variability of phytoplankton and the intrinsic difficulties of species identifications, however, combine in making reiterate assessments of this component of marine biota particularly demanding. Coarse levels of taxono ...

Abstract:
... Under conditions of rapid urbanization, quantitative measurement of the expansion characteristics of urban landscapes and evaluation of their spatial and temporal differentiation properties is an important scientific problem. The Multi-order Adjacency Index (MAI) is an effective indicator of the quantitative characteristics of urban landscape expansion; however, it cannot directly reflect the spat ...

Abstract:
... Environmental and spatial–temporal processes are proposed as important mechanisms regulating permanent pond communities, but comprehensive research of these factors at fine scales (i.e. patches or microhabitats) is still lacking. Here, we investigated environmental, spatial, and temporal variables influencing community structure and diversity (α, β, γ) in pond microhabitats over one annual cycle ( ...

Abstract:
... The concerted action of commercial esterases, proteases and amidases has been demonstrated to be relevant in polyurethane (PU) degradation by in vitro experiments. However, the spatial and temporal dynamics of these activities during PU biodegradation by PU-degrading bacteria have not been addressed. Here, we examined the capability of Alicycliphilus denitrificans BQ1 to biodegrade the polyester ( ...

Abstract:
... Time-varying parameters, which are often expressed in functional forms, have been widely used to improve hydrological modeling. Here, we assume that the time-varying parameters may be caused by deficiencies of the model structures. To justify this point, the SIMHYD model was selected as the base model, and the ensemble Kalman filter (EnKF) was used to identify the temporal variation of parameters. ...
