  1. An adaptive-noise Augmented Kalman Filter approach for input-state estimation in structural dynamics 

    Vettori S.; Di Lorenzo E.; Peeters B.; et al. (2023)
    Mechanical Systems and Signal Processing
    The establishment of a Digital Twin of an operating engineered system can increase the potency of Structural Health Monitoring (SHM) tools, which are then bestowed with enhanced predictive capabilities. This is particularly relevant for wind energy infrastructures, where the definition of remaining useful life is a main driver for assessing the efficacy of these systems. In order to ensure a proper representation of the physical structure, ...

  2. Palm oil and the Roundtable of Sustainable Palm Oil (RSPO) label: Are Swiss consumers aware and concerned? 

    Wassmann B.; Siegrist M.; Hartmann C. (2023)
    Food Quality and Preference
    Palm oil is commonly and increasingly used in many products, despite its association with various problematic ecological, social, and health-related issues. The international Roundtable of Sustainable Palm Oil (RSPO) label is intended to guide consumers toward more sustainable palm oil product purchases. Unfortunately, it is often the case that consumers profess concern for specific food sustainability issues, yet fail to translate this ...

  3. Latency and geofence testing of wireless emergency alerts intended for the ShakeAlert® earthquake early warning system for the West Coast of the United States of America 

    McBride S.K.; Sumy D.F.; Llenos A.L.; et al. (2023)
    Safety Science
    ShakeAlert, the earthquake early warning (EEW) system for the West Coast of the United States, attempts to provides crucial warnings before strong shaking occurs. However, because the alerts are triggered only when an earthquake is already in progress, and the alert latencies and delivery times are platform dependent, the time between these warnings and the arrival of shaking is variable. The ShakeAlert system uses, among other public ...

  4. Tackling Climate Change with Machine Learning 

    Rolnick D.; Donti P.L.; Kaack L.H.; et al. (2023)
    ACM Computing Surveys
    Climate change is one of the greatest challenges facing humanity, and we, as machine learning (ML) experts, may wonder how we can help. Here we describe how ML can be a powerful tool in reducing greenhouse gas emissions and helping society adapt to a changing climate. From smart grids to disaster management, we identify high impact problems where existing gaps can be filled by ML, in collaboration with other fields. Our recommendations ...

  5. Relationships between geochemical properties and microbial nutrient acquisition in tropical forest and cropland soils 

    Kidinda L.K.; Doetterl S.; Kalbitz K.; et al. (2023)
    Applied Soil Ecology
    Land-use conversion can profoundly modify geochemical and microbial properties that drive organic carbon (C) dynamics in tropical soils. However, it is unclear how microbes adjust nutrient acquisition strategies to changing geochemical properties across deeply weathered soils developed from geochemically contrasting parent material. Here we show that along a geochemical gradient in forest and cropland, a proxy variable, the chemical index ...

  6. A new bound for the Brown–Erdős–Sós problem 

    Conlon D.; Gishboliner L.; Levanzov Y.; et al. (2023)
    Journal of Combinatorial Theory. Series B
    Let f(n,v,e) denote the maximum number of edges in a 3-uniform hypergraph not containing e edges spanned by at most v vertices. One of the most influential open problems in extremal combinatorics then asks, for a given number of edges e≥3, what is the smallest integer d=d(e) such that f(n,e+d,e)=o(n2)? This question has its origins in work of Brown, Erdős and Sós from the early 70's and the standard conjecture is that d(e)=3 for every ...

  7. The Potential of Open Lists for the Election of Women to the German Bundestag. Results of a Survey Experiment 

    Rudolph L.; Däubler T.; Menzner J. (2022)
    Politische Vierteljahresschrift
    Women are underrepresented in the German parliament (Bundestag), especially in parties in and to the right of the political center. Gender quotas are frequently discussed as a remedy, but they infringe on the liberties of parties, candidates, and voters. In contrast, open lists receive little attention, although they would avoid these constitutional issues. Therefore, we examine how many German voters – overall and by party – would choose ...

  8. Study on the internal crack network of the ASR-affected concrete by the tomography-based numerical model 

    Gallyamov E.R.; Shakoorioskooie M.; Molinari J.F. (2022)
    Cement and Concrete Research
    In this paper, we present a novel finite element model to simulate alkali-silica reaction in a realistic concrete meso-structure. Application of the internal ASR loading leads to the evolution of multiple deviated cracks and corresponding macroscopic expansion. A particular crack-extension algorithm and a solution scheme provide numerical stability and allow to model complicated crack patterns while preserving the physics. The predictive ...

  9. Reflecting on the environmental impact of the captured carbon feedstock 

    Moretti, Christian (2023)
    Science of The Total Environment
    Climate change mitigation potentials of carbon capture and utilization (CCU) closely depend on the energy and chemicals used to capture the chemically inert CO2. The potential environmental benefits of CCU are typically assessed using Life Cycle Assessment (LCA) methodology. Although LCA is a standardized method, modelling CO2 as a carbon feedstock instead of an emission introduces an ambiguous “multifunctionality issue”. Inconsistent ...

  10. Leakage does not fully offset soy supply-chain efforts to reduce deforestation in Brazil 

    Villoria, Nelson; Garrett, Rachael; Gollnow, Florian; et al. (2022)
    Nature Communications
    Zero-deforestation supply chain policies that leverage the market power of commodity buyers to change agricultural producer behavior can reduce forest clearing in regions with rapid commodity expansion and weak forest governance. Yet leakage—when deforestation is pushed to other regions—may dilute the global effectiveness of regionally successful policies. Here we show that domestic leakage offsets 43-50% of the avoided deforestation ...

  12. Finite element simulations of hydraulic fracturing: A comparison of algorithms for extracting the propagation velocity of the fracture 

    Pezzulli, Edoardo; Nejati, Morteza; Salimzadeh, Saeed; et al. (2022)
    Engineering Fracture Mechanics
    The finite element method is a powerful and general numerical method used to simulate subsurface processes. In this paper, we take recent hydraulic fracturing propagation algorithms and assess their performance when used within the finite element framework. In particular, we evaluate aperture and energy-based methodologies that are capable of extracting the propagation velocity of a hydraulic fracture propagating throughout the toughness ...

  13. Combined loading of RC pile groups in clay accounting for N–M interaction 

    Psychari, Antonia; Anastasopoulos, Ioannis (2022)
    Soil Dynamics and Earthquake Engineering
    Motivated by the need for retrofit of existing bridges, this paper explores the nonlinear response of pile groups in clay under combined loading. The problem is analysed numerically, employing a kinematic hardening model for soil, and the Concrete Damaged Plasticity (CDP) model for the reinforced concrete (RC) piles. Using a reference 2 × 1 pile group, it is shown that three resistance mechanisms are mobilized: axial pile loading (Max), ...

  14. Transient acceleration events in LISA Pathfinder data: Properties and possible physical origin 

    Armano M.; Audley H.; Baird J.; et al. (2022)
    Physical Review D
    We present an in depth analysis of the transient events, or glitches, detected at a rate of about one per day in the differential acceleration data of LISA Pathfinder. We show that these glitches fall in two rather distinct categories: fast transients in the interferometric motion readout on one side, and true force transient events on the other. The former are fast and rare in ordinary conditions. The second may last from seconds to hours ...

  15. Precise determination of the low-energy electronuclear Hamiltonian of LiY1-x Hox F4 

    Beckert A.; Grimm M.; Hermans R.I.; et al. (2022)
    Physical Review B
    The insulating rare-earth magnet LiY1-xHoxF4 has received great attention because a laboratory field applied perpendicular to its crystallographic caxis converts the low-energy electronic spin Hamiltonian into the (dilute) transverse field Ising model. The mapping between the real magnet and the transverse field Ising model is strongly dependent on the exact nature of the low-energy Hamiltonian for the material, which can be determined ...

  16. Developing of biophysical food for monitoring postharvest supply chains for avocado and potato and deploying of biophysical apple 

    You L.; Schudel S.; Defraeye T. (2023)
    Journal of Food Engineering
    Horticultural products are prone to high postharvest losses due to their perishability and susceptibility to drivers for food decay, including temperature. A narrow temperature window must typically be maintained to prevent accelerated decay and, at the same time, thermal damage, such as chilling injury. Food simulators or so-called biophysical food help monitor temperature anomalies in the postharvest cold chain, and optimize refrigerated ...

  17. Metabolic reconstitution of germ-free mice by a gnotobiotic microbiota varies over the circadian cycle 

    Hoces D.; Lan J.; Sun W.; et al. (2022)
    PLoS Biology
    The capacity of the intestinal microbiota to degrade otherwise indigestible diet components is known to greatly improve the recovery of energy from food. This has led to the hypothesis that increased digestive efficiency may underlie the contribution of the microbiota to obesity. OligoMM12-colonized gnotobiotic mice have a consistently higher fat mass than germ-free (GF) or fully colonized counterparts. We therefore investigated their ...

  18. Dos and don'ts in large animal models of aortic insufficiency 

    Weisskopf M.; Glaus L.; Trimmel N.E.; et al. (2022)
    Frontiers in Veterinary Science
    Aortic insufficiency caused by paravalvular leakage (PVL) is one of the most feared complications following transcatheter aortic valve replacement (TAVI) in patients. Domestic pigs (Sus scrofa domestica) are a popular large animal model to study such conditions and develop novel diagnostic and therapeutic techniques. However, the models based on prosthetic valve implantation are time intensive, costly, and often hamper further hemodynamic ...

  19. earch for a W′ boson decaying to a vector-like quark and a top or bottom quark in the all-jets final state at √s = 13 TeV 

    Tumasyan A.; Adam W.; Andrejkovic J.W.; et al. (2022)
    Journal of High Energy Physics
    A search is presented for a heavy W′ boson resonance decaying to a B or T vector-like quark and a t or a b quark, respectively. The analysis is performed using proton-proton collisions collected with the CMS detector at the LHC. The data correspond to an integrated luminosity of 138 fb−1 at a center-of-mass energy of 13 TeV. Both decay channels result in a signature with a t quark, a Higgs or Z boson, and a b quark, each produced with a ...

  20. General framework for cyclic and fine-tuned causal models and their compatibility with space-time 

    Vilasini V.; Colbeck R. (2022)
    Physical Review A
    Causal modeling is a tool for generating causal explanations of observed correlations and has led to a deeper understanding of correlations in quantum networks. Existing frameworks for quantum causality tend to focus on acyclic causal structures that are not fine-tuned i.e., where causal connections between variables necessarily create correlations between them. However, fine-tuned causal models (which permit causation without correlation) ...
