Abstract:
... The Iowa caucuses are the inaugural event of the American presidential nomination process. When the state Democratic Party failed to report the 2020 caucus results in a timely manner, researchers began to assess how party and press officials co-constructed the events. This research presents an in-depth case of the Iowa state and local Democratic Party’s public communication response regarding an e ...

Abstract:
... To avert the degradation information island brought by a single model for state estimation of lithium-ion batteries (LIBs), multi-model integration is well worth being extended for health evaluation. A cloud-edge collaboration strategy that integrates multi-model adaptation and machine learning is proposed for battery capacity prediction in lifespan. In this respect, multiple individual algorithms ...

Abstract:
... Watershed models are robust tools that inform management and policy in a variety of sectors, but these models are often neglected through time due to economic or technical constraints. Additionally, they are not readily accessible tools for key decision makers. Conversely, machine learning models are robust alternatives to common hydrologic modeling frameworks. The random forest algorithm specific ...

Abstract:
... Rainfall is arguably the most important yet most variable input for rainfall-runoff hydrologic models. In this study, the authors search for the characteristics of radar-rainfall estimates that are most important for skillful streamflow predictions. They perform comprehensive hydrologic investigations of radar-rainfall characteristics, including spatiotemporal resolution, radar range visibility, s ...

Abstract:
... Context Vegetation quantity and quality influence the degree large grazers drive grassland structural heterogeneity. Invasive plants threaten the function of cross-scale interactions that exist when multiscale effects such as fire and grazing interplay to shape structural heterogeneity patterns. Objectives We investigated how grazing pressure and time since fire at the patch-scale influenced forag ...

Abstract:
... Despite potential importance of tributaries to Shovelnose sturgeon populations and historical declines range wide, limited population demographic and sampling efficiency information exists on shovelnose sturgeon populations in tributaries of the Upper Mississippi River. As such, we sought to evaluate the catch statistics of boat electrofishing, drifted trammel netting, and otter trawling for asses ...

Abstract:
... This study surveyed 258 organic grain farmers in Iowa in the U.S. Midwest. We identified seven areas of challenges related to organic grain farming adoption: organic farming operations, marketing, policy, finance, inputs and information, social pressures, and land tenure. Respondents reported three key areas where extension programs were needed: education, research, and technical services. Regardi ...

Abstract:
... This communication introduces HLM-Tetis, which is a model structure coupled to the Hillslope Link Model (HLM) framework developed by the Iowa Flood Center. The model was designed to improve some limitations of previous HLM model structures. The following changes have been made: (1) modules to simulate snow processes; (2) better flexibility to simulate infiltration and percolation; (3) more flexibi ...

Abstract:
... The upper Mississippi River (UMR) contains diverse, dense, and reproducing assemblages of native freshwater mussels. In the case of an injury to mussels and their habitats, such as a hazardous material spill, train derailment, or barge grounding, resource managers have few restoration strategies. Resource managers need a means to document, quantify, and mitigate adverse effects on mussels resultin ...

Abstract:
... Malnutrition is common among older adults and is related to quality of life, cognitive function, and depression. To what extent nutrition interventions can improve these outcomes remains unclear. The aim of this study was to investigate the effect of nutrition therapy on health-related quality of life (EQ-5D), self-rated health, cognitive function, and depression in community dwelling older adults ...

Abstract:
... Porcine sapovirus (SaV) was first identified by electron microscopy in the United States in 1980 and has since been reported from both asymptomatic and diarrhoeic pigs usually in mixed infection with other enteric pathogens. SaV as the sole aetiological agent of diarrhoea in naturally infected pigs has not previously been reported in the United States. Here, we used four independent lines of evide ...

Abstract:
... Within-season estimates of crop-specific planted area, conditions, and expected yields are critical for decision- and policy-making related to agriculture and food security. However, these estimates require in-season crop type maps which are not currently widely available. Machine learning and remote sensing data can be used to create crop type maps that provide crop-specific land cover classifica ...

Abstract:
... A circular economy (CE) aims to decouple human activities from economic activities and resource use, and its overall goal is reducing or avoiding negative environmental externalities. The newly developed Circular Economy Lifecycle Assessment and Visualization (CELAVI) framework simulates changes in supply chain environmental impacts as it transitions toward circularity. This study expands CELAVI b ...

Abstract:
... The severe manipulation of soil that occurs in the right‐of‐way (ROW) easement areas for pipeline installation leads to soil degradation and yield loss. The objectives of this study were to investigate the use of the Visual Evaluation of Soil Structure method (VESS) and root litter sampling as alternative ways to characterize pipeline installation impacts on soil degradation. Digital images of agg ...

Abstract:
... As laying hen housing styles change throughout Iowa to meet legislative and consumer demands, drying of manure can be economically expensive and energy intensive. With about 50% of total electricity consumption and about 60% of annual electricity costs attributed to manure drying, this represents an opportunity for producers to decrease production costs while reducing electrical grid strain. To un ...

Serum samples from 24 subjects (6 mother–daughter and 6 mother–son dyads) in a rural community (Columbus Junction, Iowa) and 24 subjects (6 mother–daughter and 6 mother–son dyads) in an urban community (East Chicago, Indiana) were analyzed for 74 sulfated metabolites of polychlorinated biphenyls (PCBs). We detected significantly higher mean concentrations of total assessed PCB sulfates in the urba ...
