A strongly polynomial-time algorithm for minimizing submodular functions

open access: yes
This paper presents a combinatorial polynomial-time algorithm for minimizing submolular set functions. The algorithm employs a scaling scheme that uses a flow in the complete directed graph on the underlying set with each arc capacity equal to thescaled ...

Polarization‐Dependent Calibration of Nitrogen‐Vacancy Axes for Precise Three‐Dimensional Magnetic Field Vector Determination

open access: yesAdvanced Physics Research, EarlyView.
Using polarization‐controllable pump light as the measurement basis, we break the polarization symmetry of NV center fluorescence and build the correlation between polarization direction and NV axis orientation, achieving high‐precision optical calibration of NV axes.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.
