1. Multipole-moment effects in ion-molecule reactions at low temperatures: part III - the He+ + CH4 and He+ + CD4 reactions at low collision energies and the effect of the charge-octupole interaction 

   Zhelyazkova, Valentina; Martins, Fernanda B., V; Merkt, Frederic (2022)

   Physical Chemistry Chemical Physics

   We present experimental and theoretical studies of the He+ + CH4 and He+ + CD4 reactions at collision energies in the k(B).(0-10) K range. Helium atoms in a supersonic beam are excited to a low-field-seeking Rydberg-Stark state and merged with a supersonic beam of CH4 or CD4 using a curved surface-electrode deflector. The ion-molecule reactions are studied within the orbit of the helium Rydberg [He(n)] electron, which suppresses ...

2. Long-term evidence for ecological intensification as a pathway to sustainable agriculture 

   MacLaren, Chloe; Mead, Andrew; van Balen, Derk; et al. (2022)

   Nature Sustainability

   Ecological intensification (EI) could help return agriculture into a 'safe operating space' for humanity. Using a novel application of meta-analysis to data from 30 long-term experiments from Europe and Africa (comprising 25,565 yield records), we investigated how field-scale EI practices interact with each other, and with N fertilizer and tillage, in their effects on long-term crop yields. Here we confirmed that EI practices (specifically, ...

3. Constraining Global Coronal Models with Multiple Independent Observables 

   Badman, Samuel T.; Brooks, David H.; Poirier, Nicolas; et al. (2022)

   The Astrophysical Journal

   Global coronal models seek to produce an accurate physical representation of the Sun's atmosphere that can be used, for example, to drive space-weather models. Assessing their accuracy is a complex task, and there are multiple observational pathways to provide constraints and tune model parameters. Here, we combine several such independent constraints, defining a model-agnostic framework for standardized comparison. We require models to ...

4. Live shopping promotions: which categories should a retailer discount to shoppers already in the store? 

   Wamsler, Julia; Vuckovac, Denis; Natter, Martin; et al. (2022)

   OR Spectrum

   Digitalization allows retailers to target customers with personalized promotions when they enter the store. Although traditional promotional retailer objectives, such as store visit, become obsolete once the shopper is already in the store, retailers still tend to target customers based on indicators that drive store visit, such as recency, frequency, and monetary value (RFM). In order to improve promotional efficiency, the authors propose ...

5. Embracing heterogeneity: Why plural understandings strengthen interdisciplinarity and transdisciplinarity 

   Vienni-Baptista, Bianca; Fletcher, Isabel; Lyall, Catherine; et al. (2022)

   Science and Public Policy

   Interdisciplinarity and transdisciplinarity are seen as promising ways to address societies' grand challenges and so have become important topics in academic and policy discourses, particularly as part of discussions about mission-oriented knowledge production and research funding processes. However, there is an important disconnect between the way these terms are defined and used in the academic literature and the way they are defined ...
