Voxel Volume Overlap: Voxel‐Size Sensitive Indicators of Subject Motion in Functional MRI
Human Brain Mapping, Volume 46, Issue 13, September 2025.Different impact of identical motion in fMRI solely due to voxel sizes, as detected by scan‐to‐scan voxel volume overlap (STSVVO; > 90% overlap: green, > 80%: yellow, > 55%: red, < 55%: gray), for 3 × 3 × 3 (A & B) vs. 2 × 2 × 2 mm (C & D). Note substantial shifts toward lower overlap with higher spatial resolution.

Managerial and Decision Economics, Volume 46, Issue 6, Page 3375-3383, September 2025.ABSTRACT Managers often say that they want to make their company more profitable by increasing the unit margin, operating margin, or margin rate, making these strategic objectives. There is some confusion in their language, as these three metrics seem to be equivalent to maximum profit.

ADAF: An Artificial Intelligence Data Assimilation Framework for Weather Forecasting
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 9, September 2025.Abstract The forecasting skill of numerical weather prediction (NWP) models critically depends on the accurate initial conditions, also known as analysis, provided by data assimilation (DA). Traditional DA methods often face a trade‐off between computational cost and accuracy due to complex linear algebra computations and the high dimensionality of the

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.Abstract Modeling density distributions along Jupiter's magnetic field lines is essential for understanding the Io plasma torus, moon plasma interactions, and plasma throughout the magnetosphere. This study compares multi‐fluid and kinetic approaches to diffusive equilibrium and the effects of different plasma distribution functions and anisotropy.

Conservation Science and Practice, Volume 7, Issue 7, July 2025.Conservation professionals often consider causal assumptions that connect strategic actions to results. Uncertainty in agricultural conservation assumptions was evaluated on three constructed value of information metrics: evidence, relevance, and reducibility. A sub‐set of assumptions was prioritized for learning‐based management.

ON NICHOLS BICHARACTER ALGEBRAS
JP Journal of Algebra, Number Theory and ApplicationsIn this paper, we define two Lie operations, and with that we define the bicharacter algebras, Nichols bicharacter algebras, etc. We obtain explicit bases for and over a connected braided vector of diagonal type with and . We give the sufficient and necessary conditions for and , respectively.

On the presentation of pointed Hopf algebras [PDF]
, 2010 We give a presentation in terms of generators and relations of Hopf algebras generated by skew-primitive elements and abelian group of group-like elements with action given via characters. This class of pointed Hopf algebras has shown great importance in

Priority search with outside options
Theoretical Economics, Volume 20, Issue 3, Page 1081-1134, July 2025.This paper examines the welfare implications of priority service in a frictional search environment with heterogeneous outside options. Priority search facilitates expedited matching with public options in the market by charging a service premium.

Left coideal subalgebras of Nichols algebras
, 2023 We determine all Nichols algebras of finite-dimensional Yetter-Drinfeld modules over groups such that all its left coideal subalgebras in the category of $\mathbb{N}_0$-graded comodules over the group algebra are generated in degree one as an algebra. Here we confine ourselves to Yetter-Drinfeld modules in which each group-homogeneous component is at ...
