Small Number of Defects per Nanostructure Leads to “Digital” Quenching of Photoluminescence: The Case of Metal Halide Perovskites
Sign Up to like & getrecommendations! Published in 2020 at "Advanced Energy Materials"
DOI: 10.1002/aenm.202001724
Abstract: Long charge carrier diffusion length and large grain size are commonly believed to be inherent properties of highly luminescent polycrystalline thin‐film semiconductors. However, exactly these two properties make luminescence very susceptible to quenching by just… read more here.

DOI: 10.1086/706087
Abstract: I argue that the human mind includes an innate domain-specific system for representing precise small numerical quantities. This theory contrasts with object-tracking theories and with domain-general theories that only make use of mental models. I… read more here.

DOI: 10.1088/1361-6501/adf24c
Abstract: River discharge estimation is crucial for effective water resource management. However, high operational and maintenance expenditures at hydrological stations have led to declining availability of reliable discharge data. Estimating river discharge with a small number… read more here.

DOI: 10.1093/ije/dyy057
Abstract: Background: Cluster randomised trials (CRTs) are increasingly used to assess the effectiveness of health interventions. Three main analysis approaches are: cluster-level analyses, mixed-models and generalized estimating equations (GEEs). Mixed models and GEEs can lead to… read more here.

DOI: 10.1109/jiot.2024.3350636
Abstract: Many estimation and reconstruction algorithms in signal processing fields can be improved themselves if the number of signals is known. However, this assumption of preknowledge is challenging in real environments. Additionally, it is often necessary… read more here.
