Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

open access: yesAI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

The role of venture‐financed startups in innovation for US agriculture

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO2 Sensing

open access: yesAngewandte Chemie, EarlyView.
Solvent intercalation disrupts the stacking order of protonated porphyrin‐based 2D COF nanoparticles, resulting in a less compactly packed structure with increased accessibility of porphyrin sites. This structural modulation leads to significantly enhanced chemiresistive NO2 sensing performance.

Austrocedrus from the Late Cretaceous of Antarctica and its implications for the early evolution of southern cypresses (Callitroideae, Cupressaceae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The modern distribution of the southern cypresses, Callitroideae (Cupressaceae), reflects a classic Gondwanan distribution. The initial diversification of Callitroideae is estimated to have occurred during the Cretaceous, yet fossils from this period are rare, hampering our understanding of its early evolutionary history.

Awareness and use of a community health worker program among racial/ethnic minority adults in Philadelphia: Results from a cross‐sectional community health survey

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Community health workers (CHW) programs are effective at reducing hospitalizations, improving mental health, and supporting health‐promoting behaviors. Research suggests awareness and use of CHW services remain uneven across communities nationally.
