Consumption in Asset Returns

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT Using information in returns, we identify the stochastic process of consumption. We find that aggregate consumption reacts over multiple quarters to innovations spanned by financial markets. This persistent component accounts for over a quarter of consumption variation. These shocks command a large and significant risk premium, driving a large

The Accuracy Smoothness Dilemma in Prediction: A Novel Multivariate M‐SSA Forecast Approach

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Forecasting presents a complex estimation challenge, as it involves balancing multiple, often conflicting, priorities and objectives. Conventional forecast optimization methods typically emphasize a single metric, such as minimizing the mean squared error (MSE), which may neglect other crucial aspects of predictive performance. To address this

Accountability in Government Use of AI: Citizen Concerns and Preferences

open access: yesPublic Administration, EarlyView.
ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

open access: yesExperimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

Decoding the Structural Complexity of Fungal α‐ and β‐Glucan Matrix via Statistical Analysis of Solid‐State NMR Chemical Shifts

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Solid‐state NMR combined with principal component analysis enables quantitative classification of fungal α‐ and β‐glucan architectures in intact cell walls, revealing conserved triple‐helical β‐1,3‐glucan conformations across species and predominantly bundled‐sheet α‐1,3‐glucan assemblies with condition‐dependent polymorphism. Statistical clustering of

How Long Is the Coast of Quantum Chemistry? Or, How to Evaluate Density Functional Theory as a Scientific Revolution

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
Within quantum chemistry, density functional theory (DFT) is a revolution. This serves as an example of a multitude of other scientific events, supporting the idea that revolutions are always large, if observed with the appropriate magnification. ABSTRACT Distinguishing scientific revolutions from normal science is a subjective, conflicting matter ...
