Investigating the Association Between Companionship and Behavior Concordance: A Dyadic Panel Study

open access: yesPersonal Relationships, Volume 32, Issue 2, June 2025.
ABSTRACT Partners in romantic relationships influence each other's behaviors through various social exchange processes. One underexplored process that is assumed to be relevant for couples' behaviors is companionship. Companionship is defined as experiencing pleasurable social interactions or engaging in shared activities for the purpose of having an ...

In Vivo Brain B1+ Inhomogeneity Correction and NOE Image Enhancement at 7 T via Flexible Metasurfaces

open access: yesNMR in Biomedicine, Volume 38, Issue 5, May 2025.
Metasurfaces were utilized to improve in vivo brain B1+ inhomogeneity at 7 T and enhance NOE imaging and multipool Z‐spectra fitting. Results showed that B1+ magnitude was increased global and locally within the temporal lobes while NOE image enhancement was also observed in the temporal lobes. ABSTRACT Nuclear Overhauser effect (NOE) MRI has been used

Tridiagonal Symmetries of Models of Nonequilibrium Physics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We study the boundary symmetries of models of nonequilibrium physics where the steady state behaviour strongly depends on the boundary rates. Within the matrix product state approach to many-body systems the physics is described in terms of matrices ...

Robust error calibration for serial crystallography

open access: yesActa Crystallographica Section D, Volume 81, Issue 5, Page 265-275, May 2025.
We present a new error‐calibration algorithm for reflection intensities in serial crystallography. We reformulate the mathematical basis of the problem and apply different levels of uncertainty to each observed lattice corresponding to its measurement accuracy.

gscramble: Simulation of Admixed Individuals Without Reuse of Genetic Material

open access: yesMolecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT While a best practice for evaluating the behaviour of genetic clustering algorithms on empirical data is to conduct parallel analyses on simulated data, these types of simulation techniques often involve sampling genetic data with replacement.

Harmonic analysis on the SU(2) dynamical quantum group

open access: yes, 2001
Dynamical quantum groups were recently introduced by Etingof and Varchenko as an algebraic framework for studying the dynamical Yang-Baxter equation, which is precisely the Yang-Baxter equation satisfied by 6j-symbols.

Who should benefit from environmental policies? Social preferences and nonmarket values for the distribution of environmental improvements

open access: yesAmerican Journal of Agricultural Economics, Volume 107, Issue 3, Page 725-751, May 2025.
Abstract The literature is replete with valuations of the costs and benefits of environmental change, yet the issue of where those impacts fall across society is rarely considered. This is a significant knowledge gap given clear evidence of social preferences regarding distributional effects reflected in both policy and protest.

Perceptual Novelty Drives Early Exploration in a Bottom‐Up Manner

open access: yesDevelopmental Science, Volume 28, Issue 3, May 2025.
ABSTRACT Children are more likely than adults to explore new options, but is this due to a top‐down epistemic‐uncertainty‐driven process or a bottom‐up novelty‐driven process? Given immature cognitive control, children may choose a new option because they are more susceptible to the automatic attraction of perceptual novelty and have difficulty ...
