The time evolution of cosmological redshift as a test of dark energy

, 2007
The variation of the expansion rate of the Universe with time produces an evolution in the cosmological redshift of distant sources (for example quasar Lyman-$\alpha$ absorption lines), that might be directly observed by future ultra stable, high ...

Simulation of Simultaneous Confidence Intervals for All Differences of Signal-to-Noise Ratios of Log-Normal Distributions

WSEAS Transactions on Systems
A low signal relative to background noise (signal-to-noise ratio: SNR) signifies a challenge in distinguishing the signal from the background noise. Herein, estimates for the simultaneous confidence intervals (SCIs) for the differences between the SNRs ...

Fiducial Confidence Intervals for Agreement Measures Among Raters Under a Generalized Linear Mixed Effects Model

A generalization of the classical concordance correlation coefficient (CCC) is considered under a three-level design where multiple raters rate every subject over time, and each rater is rating every subject multiple times at each measuring time point. The ratings can be discrete or continuous.

Selective Modulation of Evidence Accumulation by Hippocampal Theta Oscillations During Mnemonic Decision‐Making

Human Brain Mapping, Volume 47, Issue 7, May 2026.
Hippocampal theta power during memory retrieval predicts evidence accumulation in a mnemonic similarity task. Trial‐level MEG signals were integrated with a linear ballistic accumulator model, revealing that theta oscillations modulate decision dynamics, linking neural variability to memory‐based discrimination performance.

Stellar Content from high resolution galactic spectra via Maximum A Posteriori

, 2005
This paper describes STECMAP (STEllar Content via Maximum A Posteriori), a flexible, non-parametric inversion method for the interpretation of the integrated light spectra of galaxies, based on synthetic spectra of single stellar populations (SSPs).

Strategic (Inconsistent) Disclosures and Sophisticated Investors: Evidence from Hedge Funds

Journal of Accounting Research, Volume 64, Issue 2, Page 923-978, May 2026.
ABSTRACT Recent SEC regulations require that qualified hedge fund advisers provide their investors with narrative disclosures of their business and operations. We find that 40% of these disclosures omit or de‐emphasize information regarding advisers' operational and investment risks when compared to other sources of public information. Funds with such “

The King Is Dead – Long Live Who? A Family and Firm Embeddedness Perspective on Succession after the CEO‐Owner's Sudden Death

Journal of Management Studies, Volume 63, Issue 3, Page 1192-1228, May 2026.
Abstract When the CEO‐owner of an SME suddenly dies, who should take over? Integrating the social embeddedness perspective with research on crisis management, we theorize that an SME's financial health gets progressively worse before it stabilizes and recovers, reflecting an inverse U‐shaped relationship between time since the CEO‐owner's sudden death ...

Statistical Issues in Astrophysical Searches for Particle Dark Matter

, 2014
In this review statistical issues appearing in astrophysical searches for particle dark matter, i.e. indirect detection (dark matter annihilating into standard model particles) or direct detection (dark matter particles scattering in deep underground ...

Automated identification of radiotherapy treatment sites from unstructured physician notes

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Purpose Ambiguous or incomplete documentation is a recurrent bottleneck in radiation oncology workflows, leading to inefficiencies in communication and potential treatment delays. Large language models (LLMs) pose a solution to addressing these ambiguities without added burden to clinical staff.
