Fluid Structure Interaction Using Modal Superposition and Lagrangian CFD
Journal of Marine Science and EngineeringThis study investigates the impact of fluid loads on the elastic deformation and dynamic response of linear structures. A weakly coupled modal solver is presented, which involves the solution of a dynamic equation of motion with external loads.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Study of the Natural Frequencies of a Disc [PDF]
, 2015 This thesis presents experimental methods designed to determine the natural frequencies of a disc in air and submerged in water. With the goal of showing the change in natural frequencies when the disc is submerged.

FEBS Letters, EarlyView.Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Crack Detection of Fan Blade Based on Natural Frequencies
International Journal of Rotating Machinery, 2018 A simple method was developed to detect damage based on a discrete mathematical model for fan blades using changes in natural frequencies combined with a fluid-structure analysis.

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Molecular Oncology, EarlyView.BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

Natural frequencies of two elementary rigid frames [PDF]
, 1964 The natural frequencies of two elementary rigid frames, the rectangular bent and the two member frame, were determined for various ratios of length, moment of inertia, and mass per unit length of the vertical and horizontal members.

Natural Frequencies of Shear Deformable Plates by Polyharmonic Splines
Journal of Applied Mathematics, 2013 We use the third-order shear deformation theory and a collocation technique with polyharmonic splines to predict natural frequencies of moderately thick isotropic plates.
