Is the World Getting Smaller? Network‐Driven Heterogeneity in Gravity‐Model Elasticities

The World Economy, EarlyView.
ABSTRACT Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks.

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Computational model of haemodynamics during atrial fibrillation

The Journal of Physiology, EarlyView.
Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

The Long Shadow of Karl Weierstraß Over the Calculus of Variations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.
