The reaction of firms' expectations to monetary policy: evidence from Norwegian firms

open access: yesThe Scandinavian Journal of Economics, EarlyView.
Abstract An important transmission channel of monetary policy is the expectations channel. However, although this channel is important in theory, it has received limited attention in the empirical literature. One reason for this lack of focus is the scarcity of data on firms' expectations.

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

Stable Cuts, NAC‐Colourings and Flexible Realisations of Graphs

open access: yesJournal of Graph Theory, Volume 113, Issue 3, Page 411-427, November 2026.
ABSTRACT A (2‐dimensional) realisation of a graph G is a pair ( G , p ), where p maps the vertices of G to R 2. A realisation is flexible if it can be continuously deformed while keeping the edge lengths fixed, and rigid otherwise. We say that G is rigid if every generic realisation of G is rigid; otherwise, G is flexible. In this paper, we investigate

Capturing Heterogeneous Time‐Variation in Covariate Effects in Non‐Proportional Hazard Regression Models

open access: yesBiometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT A central focus in survival analysis is examining how covariates affect survival time. These covariate effects are often found to be either time‐varying, heterogeneous—such as being specific to patients, treatments, or subgroups—or exhibit both characteristics simultaneously. While the standard model, the Cox proportional hazards model, allows

Appendicular Skeletal Muscle Mass and Sarcopenia as Prognostic Markers in Amyotrophic Lateral Sclerosis

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Amyotrophic lateral sclerosis (ALS) is characterized by progressive muscle wasting and functional decline. Prognostic assessment in clinical practice relies largely on functional scales and traditional anthropometric measures. The prognostic relevance of muscle mass, muscle strength and sarcopenia in ALS remains incompletely defined.
