Article Abstract
This study investigated miscible fingering phenomena in a saturated porous medium due solely to fluid density differences. The objective was to determine dissolved salt concentrations in the porous medium and, thus, local fluid density with high temporal resolution and covering substantial volume. A magnetic resonance imaging method, which can achieve this goal by adding Cu(II)SO(4) to salt solutions, has been developed. This method was applied here to observe and quantify three-dimensional miscible fingering for the initial unstable layering of saltwater above freshwater. Additionally, characteristic properties were defined and evaluated to facilitate a more meaningful comparison with numerical simulations.

Introduction: Climate health is gaining prominence in medical curricula worldwide, with academic and healthcare institutions setting targets to reach carbon net zero. However, the integration of evidence-based strategies to reduce carbon footprint in medical education is constrained by a scarcity of research. This research study uses a novel approach to quantifying the carbon footprint of three teaching modalities within an undergraduate medical curriculum.

Background: Carotid web (CaW) is a rare fibromuscular dysplasia lesion at the carotid bifurcation linked to thromboembolic events in young patients. CaW-induced hemodynamic disturbances contribute to thrombosis, but the impact of CaW morphology on long-term thrombotic risk remains unclear.
Method: This study developed three-dimensional numerical models based on patient-specific carotid artery anatomy with CaW angles of 30°, 60°, and 90° (models A, B, and C).

Tumour growth involves dynamic interactions among tumour cells, extracellular materials, and host tissue. The tumour exerts mechanical stresses on the host tissue and simultaneously experiences compression across the tumour-host interface. This article presents a mathematical model that mimics an in vivo set-up, where an avascular tumour is surrounded by healthy/normal tissue, utilizing conservation principles for the constituents in each region.

As a 2D material with distinctive ferroelectric properties, InSe offers significant potential for the applications in information memory and advanced data storage technologies. It also exhibits a complex phase diagram that is highly sensitive to temperature and pressure variations, resulting in diverse lattice configurations. While extensive studies have focused on the phase transition behavior of InSe, its impact on phonon transport remains largely unexplored.
