State of the Art in High-Load Multi-Rotational Disc Bearings: Design, Practice, and Future Needs

High-load multi-rotational (HLMR) disc bearings have been available domestically since the 1970s. In the decades since, they have become an increasingly attractive option for use when bridges require higher rotations or loads than typical elastomeric bearings can transfer. These...

Sex ratio shapes female response to sexual conflict in the wild

Abstract Chronically male-biased sex ratios are predicted to intensify sexual conflict and reduce female fitness. Yet empirical tests of female responses in natural settings are rare. We tested how female reproductive performance depends on social environment in the field using t...

Abstract This study examines the effect of public disclosure of financial misconduct in the retail banking industry on the real economy. We propose that strengthened public disclosure of misconduct imposes disciplinary pressure which improves services and intermediation in the re...

Conceptual System Design Case Study for Decision Analysis

As part of organizations pursuing innovation, systems engineering teams include experts in decision-driven data generation, analysis, and synthesis. These experts provide skill in crafting decision support models that show the relationship between decision alternatives and fundam...

Evaluation of Human Stem Cell Conditioned Medium and Culture Conditions on Alleviating Elastase-Compromised Human Aortic Smooth Muscle Cell Function

Abstract Cardiovascular health depends critically on the integrity of the vascular extracellular matrix (ECM) and the behavior of vascular smooth muscle cells (VSMCs), both of which can be adversely affected in vascular diseases. This study quantitatively evaluates the therapeuti...

Sublethal Effects of Crude Oil Exposure Alter Population‐Level Responses in an Individual Based Model of a Passerine Bird

Although large oil spills cause intense ecological damage and receive heavy media and research attention, small spills occur much more frequently and have ecological consequences. Currently, assessment of damage to wildlife after oil spills of any magnitude primarily involves car...
