A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, EarlyView.
This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.

Kidney Transplant Recipients Develop Nasal Mucosal Antibodies to SARS‐CoV‐2 With ACE2‐Inhibiting Activity Following mRNA Vaccination

Transplant Infectious Disease, EarlyView.
Kidney transplant recipients develop nasal mucosal antibodies after systemic COVID‐19 vaccination, which are able to inhibit binding of SARS‐CoV‐2 to the ACE2 receptor, but at a lower concentration than the general population. ABSTRACT Background Less than 60% of kidney transplant recipients (KTRs) become IgG seropositive for the viral spike (S ...

Investigation of Keel Curvature Effect on the Hydrodynamic Characteristics of a V-Shaped Planing Surface

International Journal of Maritime Technology, 2015
In this paper, three-dimensional two phase turbulent free surface flow is solved by an in-house code. The incompressible Reynolds average Navier-Stocks equations (RANS) with k-ε turbulence model are solved by the finite volume method in the non ...

Microscopic seepage simulation of gas and water in shale pores and slits based on VOF

Open Physics
The microscopic pore-fracture structure and wettability have a significant influence on the two-phase seepage of shale gas and water. Due to the limitation of experimental conditions, the seepage patterns of gas and water in shale pores and slits under ...

Optimized Mesh Zoning for Dam Bottom Outlet CFD Simulations Using Richardson Extrapolation and Grid Convergence Analysis

Engineering Reports, Volume 8, Issue 6, June 2026.
A Richardson‐extrapolation–based mesh zoning framework is developed to optimize CFD simulation accuracy and computational efficiency in dam bottom outlet flows. Using six mesh scenarios and multi‐parameter convergence analysis (pressure, velocity, TKE), the method identifies an optimal fine‐resolution zone around the gate and progressively coarser ...

Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

Energy Science &Engineering, Volume 14, Issue 6, Page 3042-3055, June 2026.
Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...

Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 247-266, June 2026.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).
