Implications of Criticality in Membrane Bound Processes

Criticality in unbounded-types branching processes

Conditions for almost sure extinction are studied in discrete time branching processes with an infinite number of types. It is not assumed that the expected number of children is a bounded function of the parent’s type. There might also be no integer m such that there is a lower positive bound, uniform over the ancestor’s type, for the probability that a population is extinct at the m-th genera...

Physical Backwash Optimization in Membrane Filtration Processes: Seawater Ultrafiltration Case

Seawater ultrafi ltration (UF) as a pretreatment of reverse osmosis (RO) process in a thermal power plant was investigated using a 100 kDa hollow fi ber membrane. The choice of the UF physical backwash conditions remains arbitrary or ensuing from a sensibility study. As the optimum must take into account the factors interactions, we led a response surface study to analy...

E-commerce processes: a study of criticality

This paper, based on interviews undertaken with consultants experienced in e-commerce engagements, has identified ten process which are critical to the success of e-commerce. The processes are: order fulfilment, revenue generation/collection, financial control, IT/Web changes, business processes, e-integration, order generation, call centre integration, 24/7 operation, and consumer behaviour. T...

Dialogic and the Emergence of Criticality in Complex Group Processes

Membrane-induced folding and structure of membrane-bound annexin A1 N-terminal peptides: implications for annexin-induced membrane aggregation.

Annexins constitute a family of calcium-dependent membrane-binding proteins and can be classified into two groups, depending on the length of the N-terminal domain unique for each individual annexin. The N-terminal domain of annexin A1 can adopt an alpha-helical conformation and has been implicated in mediating the membrane aggregation behavior of this protein. Although the calcium-independent ...
