Atherosclerotic plaque rupture can initiate stroke or myocardial infarction. Lipid-rich plaques with thin fibrous caps have a higher risk to rupture than fibrotic plaques. Elastic moduli differ for lipid-rich and fibrous tissue and can be reconstructed using tissue displacements estimated from intravascular ultrasound radiofrequency (RF) data acquisitions. This study investigated if modulus rec...

Osteoblast differentiation of mesenchymal stem cells is regulated by both soluble factor (e.g., bone morphogenetic proteins (BMP)) and mechanically transduced signaling, but the mechanisms have only been partially elucidated. In this study, physical association of BMP Receptor I (BMPRI) with integrin β1 sub-unit (Iβ1) was hypothesized to mediate osteoblast differentiation of rat bone marrow-der...

As one of the most important two-dimensional (2D) materials, BN nanosheets attracted intensive interest in the past decade. Although there are many methods suitable for the preparation of BN sheets, finding a cheap and nontoxic way for their mass and high-quality production is still a challenge. Here we provide a highly effective and cheap way to synthesize gram-scale-level well-structured BN n...

Abstract In this paper, we study two-loop contribution to the effective action of a two-dimensional non-linear sigma model. We derive new formula, which can be applicable regularization general type. As examples, obtain known results for dimensional and investigate types cutoff one. Also, discuss non-local contributions restrictions on regularization.

Abstract. Due to age, structural deterioration, and other factors, concrete constructions such as beams columns will inevitably deteriorate. The growth of nanomaterials recent advances in multidisciplinary research has broadened cement composites' applicability various fields. A self-sensing composite can detect its own deformation, strain, stress by changing electrical characteristics, which m...
