This paper examines the structure, behavior and performance of the N95 respirator market in the U.S. before and during the COVID-19 pandemic (2020-early 2022). It focuses on the behavior and performance of government and private sector organizations in the allocation of scarce supplies of N95...

Ranking suppliers performance is one of the central issues of supplier management. In supplier selection, most quantitative analysis assumes that any two suppliers are comparable on any criteria. This assumption is then used to rank the suppliers. In practice, however, suppliers are not always...

This study addresses the problem of improving the performance of water quality trading auctions when information about delivery coefficients of nonpoint sources is revealed to potential sellers. We consider the case in which a regulator participating in an auction market as a buyer of water...

Pupil segmentation is a first and important topic of iris recognition, identity recognition and eye movement information extraction for mental analysis. However, due to the negative effects of eyelash occlusion, eyelid occlusion and off-gaze deflection, making a precise pupil segmentation is a...

Here we present a novel numerical method by exploiting periodicity to analyze a real-scale reverse electrodialysis (RED), including an unlimited number of microstructures and electrode segmentations. Flow and current distributions are calculated for a unit cell with on-demand adjustment of...

We hypothesize that firms required by SFAS No. 131 to begin disclosing segment information attempt to counteract potential competitive harm by increasing information redaction. Using a difference-in-difference setting, we find that firms increasing the number of reported segments after the rule...
