Laser-induced graphene (LIG) has gained considerable attention recently due to its unique properties and potential applications. In this study, we investigated using LIG in polyimide (PI) as a material for antenna The LIG-−PI composite was prepared by facile picosecond laser (1064 nm) irradiation process, which resulted conductive network within the PI matrix. Furthermore, formation confirmed R...

The interaction of vascular smooth muscle cells (SMCs) and extracellular matrix plays important roles in vascular remodeling. We investigated the signaling pathways involved in SMC-induced matrix contraction and SMC migration in three-dimensional (3D) collagen matrix. Matrix contraction is inhibited by the disruption of actin filaments but not microtubules. Therefore, we investigated the roles ...

Let P={Pij; i, j=l, 2, ... , r} be the transition matrix of a stationary, regular Markov chain C with r states and a={ai; i=l, 2, ... , r} be its limiting vector which represents the stationary distribution of the chain. Suppose that there is another regular Markov chain C' with the transition matrix pI ={p;j} and the limiting vector a' ={a;}. If pI is close to P, we can expect that a' is also ...

Brushless DC motors (BLDC) are widely used in industrial areas. The BLDC motors are driven either by indirect ACAC converters or by direct AC-AC converters. Direct AC-AC converters i.e. matrix converters are used in this paper to drive the three phase BLDC motor and it eliminates the bulky DC link energy storage element. A matrix converter converts the AC power supply to an AC voltage of variab...

BACKGROUND Tks5 regulates invadopodium formation, but the precise timing during invadopodium lifetime (initiation, stabilization, maturation) when Tks5 plays a role is not known. RESULTS We report new findings based on high-resolution spatiotemporal live-cell imaging of invadopodium precursor assembly. Cortactin, N-WASP, cofilin, and actin arrive together to form the invadopodium precursor, f...

Diacylphosphatidylinositol (PI) is the starting reactant in the process of phosphatidylinositide-related signal transduction mediated through the lipid raft domain. We investigated intermolecular interactions of PI with major raft components, sphingomyelin (SM) and cholesterol (Chol), using surface pressure-molecular area (π-A) isotherm measurements. The classical mean molecular area versus com...

eactive compatibilization, in which a compatibilizer is formed by an interfacial coupling between wo reactive polymers, is commonly used when blending immiscible homopolymers. We consider eactive compatibilization using two multifunctional reactive polymers, which leads to a rosslinked copolymer at the interface. Experiments were conducted on model blends of olydimethylsiloxane PDMS and polyiso...

Focal adhesions are an elaborate network of interconnecting proteins linking actin stress fibers to the extracellular matrix substrate. Modulation of the focal adhesion plaque provides a mechanism for the regulation of cellular adhesive strength. Using interference reflection microscopy, we found that activation of phosphoinositide 3-kinase (PI 3-kinase) by PDGF induces the dissipation of focal...
