Cecile Pickart 1954–2006

When an unusually gifted scientist passes away prematurely, and when her friendship was so widely treasured , the intensity of sadness is difficult to convey. Cecile Pickart shaped the ubiquitin field for over two decades with equal parts creativity, rigor, and fairness (see photo). Her finest work centered on the polyubiquitin chain, the primary signal for protein degradation by the proteasome...

M m m Queue with Balking, Reneging and Additional Servers

In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...

M M m K Queue With Additional Servers and Discouragement (RESEARCH NOTE)

Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals with multi-server queueing system with additional servers and discouragement. The customers arrive in poisson fashion and are served exponentially by a pool of permanent and addi...

Rebreathing in a Double T-piece System by Anis Baraka, Bernard Brandstater, Musa Muallem and Cecile Seraphim Summary

A double T-piece paediatric system is described. During spontaneous respiration, the system will perform like a Magill system if the fresh gas flow is delivered via the distal T-piece; the proximal T-piece will provide an outlet. During controlled ventilation the set will perform like a Rees system if the fresh gas flow is delivered via the proximal T-piece; the distal T-piece will provide a co...
