The impact of agent definitions and interactions on multiagent learning for coordination in traffic management domains
(2020)Autonomous Agents and Multi-Agent SystemsThe state-action space of an individual agent in a multiagent team fundamentally dictates how the individual interacts with the rest of the team. Thus, how an agent is defined in the context of its domain has a significant effect on team performance when learning to coordinate. In this work we explore the trade-offs associated with these design choices, for example, having fewer agents in the team that individually are able to process and ...Journal Article -
Anxieties of the Dominant: Legal, Social, and Religious in the Politics of Religious Conversion in India
(2022)Oxford Journal of Law and ReligionThe promulgation of the new state-level conversion laws in India or some changes in already existing ones by ordinances is premised upon various conspiracy theories of Hindu fundamentalists against Muslims. Implicit in and placed at the centre of these new anti-conversion laws and public debates thereof is the conspiracy theory of love-jihad that Muslim men lure Hindu women on the pretext of love and get them convert to Islam to eventually ...Journal Article -
Photosynthetic capacity dominates the interannual variation of annual gross primary productivity in the Northern Hemisphere
(2022)Science of The Total EnvironmentAnnual gross primary productivity (AGPP) of terrestrial ecosystems is the largest carbon flux component in ecosystems; however, it's unclear whether photosynthetic capacity or phenology dominates interannual variation of AGPP, and a better understanding of this could contribute to estimation of carbon sinks and their interactions with climate change. In this study, observed GPP data of 494 site-years from 39 eddy covariance sites in ...Journal Article -
Exploring actors' perceptions of the precision agriculture innovation system – A Group Concept Mapping approach in Germany and Switzerland
(2023)Technological Forecasting and Social ChangePrecision Agriculture Technologies (PATs) promise to enhance productivity and foster sustainability. However, attempts to explain the low adoption of PATs, particularly in Europe, lack attention to the role of shared understanding of PATs among actors in the development and diffusion of this innovation. To uncover what could guide the emergence of a collective understanding of PATs, we explore how the actors comprising the nascent innovation ...Journal Article -
Temperature distribution in a gas-solid fixed bed probed by rapid magnetic resonance imaging
(2023)Chemical Engineering ScienceControlling the temperature distribution inside catalytic fixed bed reactors is crucial for yield optimization and process stability. Yet, in situ temperature measurements with spatial and temporal resolution are still challenging. In this work, we perform temperature measurements in a cylindrical fixed bed reactor by combining the capabilities of real-time magnetic resonance imaging (MRI) with the temperature-dependent proton resonance ...Journal Article -
Temporal variations of carbon and water fluxes in a subtropical mangrove forest: Insights from a decade-long eddy covariance measurement
(2023)Agricultural and Forest MeteorologyMangroves, highly efficient ecosystems in sequestering CO2, are strongly impacted by climate change. The lack of long-term observation in mangroves hinders the evaluation of seasonal and inter-annual variability in carbon and water fluxes and their responses to various environmental drivers. In this study, we measured net ecosystem CO2 exchange and evapotranspiration between the atmosphere and subtropical mangroves using the eddy covariance ...Journal Article -
Networking the forest infrastructure towards near real-time monitoring - A white paper
(2023)Science of The Total EnvironmentForests account for nearly 90 % of the world's terrestrial biomass in the form of carbon and they support 80 % of the global biodiversity. To understand the underlying forest dynamics, we need a long-term but also relatively high-frequency, networked monitoring system, as traditionally used in meteorology or hydrology. While there are numerous existing forest monitoring sites, particularly in temperate regions, the resulting data streams ...Journal Article -
Towards monitoring stem growth phenology from space with high resolution satellite data
(2023)Agricultural and Forest MeteorologyRadial stem growth is a key ecosystem process resulting in long-term carbon sequestration. Despite recognition of its importance to global carbon cycling, high uncertainties remain regarding how radial growth phenology (e.g., the onset, mid, and cessation of radial growth) will be affected by climate change. In this study, we evaluated to what extent high spatially (3 × 3 m) and temporally (up to daily) resolved satellite imagery from ...Journal Article -
Predominant contributions through lichen and fine litter to litterfall mercury deposition in a subalpine forest
(2023)Environmental ResearchLitterfall, typically referring to needles/leaves, may stand for >50% of the total mercury (Hg) deposition in forest ecosystems. By detailed categorisation, we reveal for the first time that the contributions through lichens and fine litter, together 9.98 μg Hg m−2 yr−1, could be as high as that in needle litter (9.96 μg m−2 yr−1) to the annual total Hg deposition (44.6 μg m−2 yr−1) in a subalpine forest in Switzerland. Noticeably, needle ...Journal Article -
Animal-associated marine Acidobacteria with a rich natural-product repertoire
(2023)ChemSponges are well known as rich sources of bioactive natural products. Various studies suggest that many of these compounds are produced by symbiotic bacteria. However, substance supplies and functional insights about the producers remain limited because cultivation remains unsuccessful. To identify alternative, sustainable sources of sponge-derived polyketides, we computationally analyzed 5,289 characterized and orphan trans-acyltransferase ...Journal Article
