Hindlimb biomechanics of Lagosuchus talampayensis (Archosauria, Dinosauriformes), with comments on skeletal morphology

open access: yesJournal of Anatomy, Volume 246, Issue 6, Page 948-973, June 2025.
The study constructs a 3D whole‐body biomechanical model of the Late Triassic archosaurian reptile Lagosuchus talampayensis, which includes reconstructions of the hindlimb musculature. The process of constructing the model revealed that numerous limb bones curated with the main specimens are from other, as‐yet‐undetermined archosaurs.

Quantitative sedimentological analysis of the aeolian–fluvial Triassic Sherwood Sandstone Group, Cheshire Basin, UK

open access: yesSedimentology, Volume 72, Issue 4, Page 1233-1274, June 2025.
ABSTRACT Sedimentological analysis of the outcropping Sherwood Sandstone Group, northern Cheshire Basin, UK, documents the preserved stratigraphic expression of water table‐controlled aeolian‐dominated erg‐margin successions (Wilmslow Sandstone Formation and lower Helsby Sandstone Formation), overlain by dryland fluvial deposits (middle Helsby ...

Semi-analytical and numerical methods for computing transient waves in 2D acoustic / poroelastic stratified media

open access: yes, 2012
Wave propagation in a stratified fluid / porous medium is studied here using analytical and numerical methods. The semi-analytical method is based on an exact stiffness matrix method coupled with a matrix conditioning procedure, preventing the occurrence

Straining Flow Effects on Sperm Flagellar Energetics in Microfluidic Cross‐Slot Traps

open access: yesSmall, Volume 21, Issue 21, May 26, 2025.
This study explores the impact of straining flow on the flagellar energetics of single trapped sperm using microfluidic cross‐slot devices. Findings reveal that higher strain rates disrupt periodic beating, reduce amplitude, and power dissipation, while maintaining frequency.

Treatment‐Free Remission Outcomes in a BCR::ABL1 Digital PCR Selected Clinical Cohort of CML Patients

open access: yesEuropean Journal of Haematology, Volume 114, Issue 5, Page 900-907, May 2025.
ABSTRACT Approximately 40%–60% of patients reaching a stable deep molecular response during TKI treatment will maintain a state of remission after TKI discontinuation, denoted as treatment‐free remission (TFR). Depth of molecular response assessed by BCR::ABL1 digital PCR prior to TKI discontinuation has demonstrated its significance as a reliable ...
