A counting proof for the smallest critical set in a Latin square
Richard Bean
A critical set in a Latin square is a set of entries that determines the square uniquely and is minimal with this property. We prove that every partial Latin square of order wi…
A tight single-change covering design with block size 6
Richard Bean
We give a tight single-change covering design with and . This answers Problem 1 of the Nineteenth British Combinatorial Conference, which asked whether such a design ex…
Critical Sets in Latin Squares and Associated Structures
Richard Winston Bean
A critical set in a Latin square of order is a set of entries in an array which can be embedded in precisely one Latin square of order , with the property that i…
Ultrasound cavitation and exfoliation dynamics of 2D materials re-vealed in operando by X-ray free electron laser megahertz imaging
Kang Xiang, Shi Huang, Hongyuan Song +22
Ultrasonic liquid phase exfoliation is a promising method for the production of two-dimensional (2D) layered materials. A large number of studies have been made in investigating th…
3D-Printed Sheet Jet for Stable Megahertz Liquid Sample Delivery at X-ray Free Electron Lasers
Patrick E. Konold, Tong You, Johan Bielecki +23
X-ray Free Electron Lasers (XFELs) can probe chemical and biological reactions as they unfold with unprecedented spatial and temporal resolution. A principal challenge in this purs…
Megahertz X-ray Multi-projection imaging
Pablo Villanueva-Perez, Valerio Bellucci, Yuhe Zhang +21
X-ray time-resolved tomography is one of the most popular X-ray techniques to probe dynamics in three dimensions (3D). Recent developments in time-resolved tomography opened the po…
