Rate of Interest and Intertemporal Preferences in Multisectoral Frameworks: A Critical View

open access: yesMetroeconomica, EarlyView.
ABSTRACT This paper analyses a closure of Sraffa's price system found in some neoclassical literature, which involves equating the rate of interest with the rate of time preference. This closure aims to reconnect the rate of interest with individuals' intertemporal preferences.

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

open access: yesExperimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Trend Inflation and the Costs of Price Dispersion in a Fiscal DSGE Model

open access: yesSouth African Journal of Economics, Volume 94, Issue 3, September 2026.
ABSTRACT Most inflation‐targeting frameworks allow for a positive trend inflation rate, yet its optimal level remains uncertain. The extended deliberation in South Africa to move from a 3%–6% target band to a 3% target (with a 1% tolerance band) illustrates this tension.

Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3104-3115, June 2026.
ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...
