Pierre Briaud, Maxime Bros, Ray Perlner, Daniel Smith-Tone
HPPC is a multivariate signature scheme submitted to the NIST PQC standardization process in response to the recent call for additional signature schemes. We show that, despite some non-standard notational choices in the submission document, HPPC can be

Survey of agricultural plastic waste in the American Midwest: usage and disposal

January 1, 2026
Author(s)
Julie Rieland, Christina Gore, Kalman Migler, Kathryn Beers
An estimated 4 % of global plastics are used for agricultural applications in forms such as films, jugs, fence posts, and hoses. However, there is limited data on actual use, and more importantly on its fate at end of life. We first present a comprehensive

Chemical Kinetics and Fire

December 31, 2025
Author(s)
Gregory Linteris, John Griffiths
The purpose of this chapter is to set out the principles of chemical kinetics as they apply to combustion in flames and fires. Chemical equilibrium, which was discussed in a previous chapter, deals with the final preferred state of a given set of reactants

Intermethod Characterization of Commercially Available Extracellular Vesicles as Reference Materials

The National Institute of Standards and Technology (NIST) is developing analytical methods to characterize extracellular vesicles (EVs) to support the urgent need for standardized EV reference materials (RMs). This study used orthogonal techniques

Light shift suppression in a CPT magnetometer using linear polarization and double frequency interrogation

December 30, 2025
Author(s)
Mario Alberto Gonzalez Maldonado, Yang Li, Jamie McKelvy, Andrey Matsko, Irina Novikova, Eugeniy Mikhailov, John Kitching, Ying-Ju Wang
We demonstrate a suppression of the light shift in a Coherent-Population-Trapping (CPT) atomic magnetometer by using linearly polarized light and a differential measurement between magnetic resonances. The radio frequency that creates the optical sidebands
