Afgeschafte CO₂-heffing was ‘stok achter de deur’ om Tata en Shell onder druk te zetten
In de week dat de Tweede Kamer de CO₂-heffing buiten werking stelde, staakten grote vervuilers de onderhandelingen met de overheid om tot minder uitstoot te komen. Die heffing was belangrijker dan tot dusver werd aangenomen: ze was de stok om bedrijven te dwingen tot vergaande vergroening. Die stok is nu weg.

Recency effect disappears when information is integrated from independent perceptual sources
Decision-making often involves integrating discrete pieces of information from distinct sources over time, yet the cognitive mechanisms underlying this integration remain unclear. In this study, we examined how individuals accumulate and integrate discrete sensory evidence. Participants performed a task involving random dot motion stimuli presented in single- and double-pulse trials. These stimuli varied in motion coherence, source consistency of pulses (either the same or orthogonal directions…

Identification of Noise-Associated Glitches in KAGRA O3GK with Hveto
Transient noise ("glitches") in gravitational wave detectors can mimic or obscure true signals, significantly reducing detection sensitivity. Identifying and excluding glitch-contaminated data segments is therefore crucial for enhancing the performance of gravitational-wave searches. We perform a noise analysis of the KAGRA data obtained during the O3GK observation. Our analysis is performed with hierarchical veto (Hveto) which identifies noises based on the statistical time correlation between…

Velocity dependence of the mass modifications of $ρ$ and $ω$ mesons in 12 GeV $p+A$ reactions
This study measured the invariant mass spectra of $ρ$ and $ω$ mesons in the \ee~decay channel for 12 GeV (12.9 GeV/$c$) $p+\mathrm{C}$ and $p+\mathrm{Cu}$ reactions ($\sqrt{s}_{NN}=5.1$ GeV) at the KEK 12-GeV Proton Synchrotron. The measured spectra were divided into three \bg\ regions to examine their velocity dependence. Across all regions, significant excesses were observed on the low-mass side of the \omegameson peak, beyond the contributions of known hadronic sources, in the data of the …

CataractSurg-80K: Knowledge-Driven Benchmarking for Structured Reasoning in Ophthalmic Surgery Planning
Cataract surgery remains one of the most widely performed and effective procedures for vision restoration. Effective surgical planning requires integrating diverse clinical examinations for patient assessment, intraocular lens (IOL) selection, and risk evaluation. Large language models (LLMs) have shown promise in supporting clinical decision-making. However, existing LLMs often lack the domain-specific expertise to interpret heterogeneous ophthalmic data and provide actionable surgical plans. …

The Identification Power of Combining Experimental and Observational Data for Distributional Treatment Effect Parameters
This paper investigates the identification power gained by combining experimental data, in which treatment is randomized, with observational data, in which treatment is self-selected, for distributional treatment effect (DTE) parameters. While experimental data identify average treatment effects, many DTE parameters, such as the distribution of individual treatment effects, are only partially identified. We examine whether, and how, combining the two data sources tightens the identified set for…

Impact of model parameter degeneracy on leptonic radiation models. The case of blazar multi-wavelength spectra
Leptonic one-zone radiation models are commonly used to describe multi-wavelength data and explore the physical properties of high-energy sources, such as active galactic nuclei. However, these models often require a large number of free parameters. In the context of possible parameter degeneracy and the complex landscape of the parameter space, we study how the choice of the fitting procedure impacts the characterization of the source properties. Furthermore, we examine how the data coverage a…

Numerical analysis of quasiperiodic oscillations in the Hartle-Thorne spacetime
We numerically analyze quasiperiodic oscillations (QPOs) using a well-established spacetime model with neutron star sources. Within the framework of general relativity, we present expressions for the fundamental frequencies of test particles in the gravitational field of a slowly rotating and slightly deformed compact object defined by the Hartle-Thorne (HT) metric. Using the Relativistic Precession Model (RPM) formulated by Stella and Morinsk, we examine quasiperiodic oscillation data from eig…

20 GeV halo-like excess of the Galactic diffuse emission and implications for dark matter annihilation
Fifteen years of the Fermi Large Area Telescope (LAT) data in the halo region of the Milky Way (MW) are analyzed to search for gamma rays from dark matter annihilation. Gamma-ray maps within the region of interest ($|l| \le 60$ deg, $10 \le |b| \le 60$ deg) are modeled using point sources, the GALPROP models of cosmic-ray interactions, isotropic background, and templates of Loop I and the Fermi bubbles, and then the presence of a halo-like component is further examined. A st…
