Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]
, 2016 The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...

Dynamic phototuning of 3D hydrogel stiffness [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Extracellular matrix (ECM) stiffness is an influential factor in many biological processes. Temporal changes in ECM stiffness are observed in cancer, cardiovascular disease, and wound healing, and are likely involved in disease progression.

VERTICAL VIBRATIONS OF BASE ISOLATED MACHINEFOUNDATIONS
Journal of Engineering, 2010 Vibration of base isolated machine foundations has been studied using the Scaled Boundary Finite Element Method (SBFEM) and the cone model method. The dynamic stiffness of soil supporting rigid massless foundation was determined.

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Evaluation of dynamic behavior of varved clays from the Warsaw ice-dammed lake, Poland
Open Geosciences, 2023 Soil stiffness degradation due to dynamic loading may result in damage to engineering structures. Therefore, dynamic soil properties gained importance in recent years in the areas where vibrations of different origins are transmitted to the ground.

Reliable Dynamic Motions for a Stiff Quadruped [PDF]
, 2009 We present a kinodynamic planning methodology for a high-impedance quadruped robot to negotiate a wide variety of terrain types with high reliability. We achieve motion types ranging from dynamic, double-support lunges for efficient locomotion over extreme obstacles to careful, deliberate foothold and body pose selections which allow for precise ...
