Analysis of Anmmap/Ph1, Ph2/N/∞ queueing system operating in a random environment

Structural basis of the myosin X PH1N-PH2-PH1C tandem as a specific and acute cellular PI(3,4,5)P3 sensor

Myosin X (MyoX) is an unconventional myosin that is known to induce the formation and elongation of filopodia in many cell types. MyoX-induced filopodial induction requires the three PH domains in its tail region, although with unknown underlying molecular mechanisms. MyoX's first PH domain is split into halves by its second PH domain. We show here that the PH1(N)-PH2-PH1(C) tandem allows MyoX ...

Computational analysis of (MAP1, MAP2)/(PH1, PH2)/N queues with finite buffer in wireless cellular networks

This paper studies a queueing model with the finite buffer of capacity K in wireless cellular networks, which has two types of arriving calls—handoff and originating calls, both of which follow the Markov arriving process with different rates. The channel holding times of the two types of calls follow different phase-type distributions. Firstly, the joint distribution of two queue lengths is de...

Multi-Objective Lead Time Control in Multistage Assembly Systems (TECHNICAL NOTE)

In this paper we develop a multi-objective model to optimally control the lead time of a multistage assembly system. The multistage assembly system is modeled as an open queueing network, whose service stations represent manufacturing or assembly operations. The arrival processes of the individual parts of the product, which should be assembled to each other in assembly stations, are assumed to...

Urinary oxalate excretion in urolithiasis and nephrocalcinosis.

AIMS To investigate urinary oxalate excretion in children with urolithiasis and/or nephrocalcinosis and to classify hyperoxaluria (HyOx). METHODS A total of 106 patients were screened. In those in whom the oxalate: creatinine ratio was increased, 24 hour urinary oxalate excretion was measured. Liver biopsy and/or genomic analysis was performed if primary hyperoxaluria (PH) was suspected. Stoo...
