 Revisiting Theories for the Growth of Single Crystalline Ice: Laboratory Data and Code to Compute the Crystal Shape Functions by Jerry Y. Harrington and Gwenore F. Pokrifka.
This data set comprises individual time-series data for crystals grown in the substrate crystal imaging chamber (Pokrifka et al., 2025) along with surrogate time-series data extracted from free fall chamber measurements (Takahashi et al., 1991).

Skeletal Age Estimation – Transition Analysis (TA3-V1.0) by George R. Milner (PI), Jesper L. Boldsen (co-PI), Stephen D. Ousley (co-PI).
A computer program, TA3-V1.0, is developed to facilitate skeletal age estimation for forensic investigations (personal identification) and archaeological research (paleodemography and paleoepidemiology).

Spatially separate production of hydrogen oxides and nitric oxide in lightning by Jena M. Jenkins and William H. Brune
The atmosphere’s most important oxidizer, the hydroxyl radical (OH), is generated in abundance by lightning, but the contribution of this electrically generated OH (LOH) to global OH oxidation remains highly uncertain. Part of this uncertainty is due to the abundant nitric oxide (NO) also generated in lightning, which could rapidly remove the LOH before it can oxidize other pollutants in the atmosphere

Information about strains in the Penn State E. coli Reference Center
he Penn State E. coli Reference Center was established in 1967 and today with approximately 90,000 isolates serves as one of the largest collections of a single bacterial species. This site is a resource for the scientific community, providing documentation of isolates in the collection, known metadata, and genomic-based resources for learning more about the strains.
