Steady state distributions for manpower models under conditions of growth
… workforce supporting the U.S. Navy and a state police organization. This study looks at such systems under conditions of change and develops the equations that describe the steady state distribution of personnel. The conditions of change include systems where recruitment is constant, …

Queueing Models for Large Scale Call Centers
… incorporates only the density the abandonment distribution at the origin, our result incorporate the entire abandonment distribution. This is accomplished by a scaling the hazard rate function of the abandonment distribution as the system moves into heavy traffic. Our main results are to obtain …

A Lyapunov analysis of LRU
… asymptotically exact TTL approximation for the steady state distribution of our LRU Markov model. We further present ongoing theoretical extensions to other variants of LRU, as well as simulations that validate our model. We conclude by proposing a variance corrected model to better approximate …

Cell fate reprogramming using transcription factor feedback overexpression
… cell back to its undifferentiated, pluripotent state would be a significant breakthrough for regenerative medicine. For example, lost or damaged cells could be replaced by patient-specific reprogrammed cells, thus providing on-demand, compatible, high-quality cells of any required type. However, …

Analyzing the make-to-stock queue in the supply chain and eBusiness settings
… knowledge to both agents. Under the continuous state approximation that the M/M/1 queue has an exponential rather than geometric steady-state distribution, we characterize the optimal centralized and Nash solutions, and show that a contract with linear transfer payments based on backorder, …

On the power of centralization in distributed processing
… demonstrate a surprising phase transition in the steady-state delay, as p changes: in the limit of a large number of stations, and when any amount of centralization is available (p > 0), the average queue length in steady state scales as log 1/1-p 1/1-[lambda] when the traffic intensity [lambda] …

Generalised Markovian analysis of timed transition systems
… onto a Markov chain through a process known as state space generation. The Markov chain thus generated can then be solved for its steady-state distribution by numerically determining the solution to a large set of sparse linear equations known as the steady-state equations. Existing techniques …

Monte Carlo simulation of ion transport of high strain ionomeric polymer transducers
… on modeling the cation transport and cation steady state distribution due to the actuation of an IPT. Ion transport in the IPT depends on the morphology of the hydrated Nafion membrane and the morphology of the metal electrodes. Recent experimental findings show that adding conducting powders …

Collaborating queues: large service network and a limit order book
We analyse the steady-state behaviour of two different models with collaborating queues: that is, models in which "customers" can be served by many types of "servers", and "servers" can process many types of "customers". The first example is a large-scale service system, such as a call centre. …

In vitro reconstitution of Central Spindle Motility
… microtubule (MT) overlaps, can influence the steady state distribution of cargoes is not understood molecularly. For example, in dividing sensory organ precursor cells, the antiparallel MT overlap of the central spindle controls the asymmetric segregation of signalling endosomes containing …

Regulation of lipid signaling at the Golgi by the lipid phosphatases hSAC1 and OCRL1
… distinct cellular compartments. This assymetric distribution of phosphoinositides is achieved by the presence of an elaborate set of lipid kinases and phosphatases operating at specific organelle membranes. The lipid phosphatase SAC1 is found in both endoplasmic reticulum (ER) and Golgi. Similar …

Deciphering the regulation of perforin-2-mediated endocytic escape in dendritic cells
… of intracellular compartments. Analysis of its steady-state distribution showed that perforin-2 was proteolytically processed with full-length and cleaved forms present in early and late endocytic compartments, respectively. Since perforin-2 was recruited to antigen-containing phagosomes, I …

Network Structures Arising from Spike-Timing Dependent Plasticity
… that the ``triplet model'' leads to a partially steady-state distribution of synaptic weights and induces Hebbian competition. The ``suppression model'' develops a stable distribution of weights when the average weight is high and shows predominantly anti-Hebbian competition. The "NMDAR-based" …

The Role of the YXXΦ Motif in CD82 Trafficking and Function
… of this motif have drastic effect on the steady state distribution of CD82. Results from the intracellular trafficking and recycling assays reveal that there is a defect in the intracellular trafficking of CD82 upon the mutation of its YXXФ motif. We found that both CD82 WT and CD82 YVAA …

Advances in the stochastic and deterministic analysis of multistable biochemical networks
… proteins may sit at one of two or more different steady state concentrations in otherwise identical cells, and in spite of them being in the same environment. Models of multisite protein phosphorylation have shown that this mechanism is able to exhibit unlimited multistability. Nevertheless, these …
