We present a hybrid cell-centred/vertex model for mechanically simulating planar cellular monolayers undergoing cell reorganisation. Cell centres are represented by a triangular nodal network, while the cell boundaries are formed by an associated vertex network. The two networks are coupled through a kinematic constraint which we allow to relax progressively. Special attention is paid to the ch...

V79 Chinese hamster cells dissociated with 1 nm EDTA retain 2 kinds of cell adhesion mechanisms, one dependent on Ca2+ and the other independent of Ca2+. Ehrlich's ascites tumour (EAT) cells are provided with neither Ca2+-dependent nor CA2+-independent mechanisms. Studies on the aggregation of cells of 25 different hybrid clones obtained by fusing these 2 lined cells revealed the following poin...

in this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hbmscs) into hepatocytes on a three-dimentional (3d) nanofibrous scaffold formed by poly (ε-caprolactone) (pcl), collagen and polyethersulfone (pes). the nanofiber was prepared by the electrospining technique. hbmscs were isolated using combining gradient density centrifugation ...

This paper investigates the effect of temperature on a hybrid energy storage system with various energy management systems. The hybrid energy storage system consists of a fuel cell, ultracapacitor and battery with associated DC/DC and DC/AC converters. The energy management strategies employed are the state machine control strategy, fuzzy frequency/logic decoupling strategy, minimization strate...

The energy conversion efficiency of hybrid organic-inorganic perovskite solar cells (PSCs) has reached a value comparable to commercially available silicon cells. main challenges for their commercialization are instability and toxicity.

The replication of mouse-tropic and xenotropic strains of murine leukemia virus in human x mouse hybrid cells was investigated. NB-tropic strains of the leukemia virus replicated efficiently in several hybrid lines, including those that contained a complete complement of human chromosomes and many mouse chromosomes. In lines with only a few mouse chromosomes, NB-tropic viruses failed to replica...

design of bridge deck with long-term strength, durability and permanence is a significant interest for engineers. one applicable solution to this challenge could be via using hybrid system consisting of conventional materials such as concrete and steel with frp plates which is also known as composite deck. since these deck are relatively new so their performance is not completely known. the pre...

This paper evaluates the performance of a grid connected hybrid system. The hybrid system consists of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC). Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. The objective of the paper is to coordinate the two control modes and determine the ref...
