Weaning-Induced Alterations to Sulfur Amino Acid Utilization in Pigs
(2023-04-24)
Weaning is one of the most stressful events for pigs. It is associated with low and variable feed intake, poor nutrient utilization, and high feed costs. A small percentage of weaned pigs do not ingest feed for several ...
Analysis and Optimization of Lithographic Performance on Massively-Parallel Electron-beam Systems
(2023-04-24)
While electron-beam (e-beam) lithography is widely used in transferring fine-feature patterns onto a substrate, its major drawback is the low throughput, especially for large-scale patterns. The massively-parallel electron-beam ...
The Impact of the Gross Book-to-market Ratio in REITs, and Corporate Reactions to PBGC Variable Rate Premium Increases
(2023-04-24)
The first two essays explore the usefulness of the gross book-to-market ratio in equity REITs.
The first essay shows that the traditional calculation of the market-to-book (and book-to-market)
ratio is flawed. We show ...
