iMetaMed, EarlyView.Combining clinical data with serum proteomics and metabolomics, the HGB–CAPZB–acetic acid model was developed as a potential diagnostic index to distinguish the active and stable stages of Helicobacter pylori‐infected chronic gastritis, and the related mechanism was explored through multi‐omics.

Stability criteria for controlled queueing networks [PDF]
, 2006 We give criteria for the stability of a very general queueing model under different levels of control. A complete classification of stability (or positive recurrence), transience and null-recurrence is presented for the two queue model. The stability and

MARKOV MODULATED FLUID QUEUES WITH BATCH FLUID ARRIVALS
Journal of the Operations Research Society of Japan, 2001 Summary: In the conventional Markov modulated fluid queue, the buffer content process has a continuous sample path. This paper concerns a Markov modulated fluid queue whose buffer content process may have jumps. This model extends not only the conventional fluid queue but also the MAP/G/1 model.

Restless bandit marginal productivity indices II: multiproject case and scheduling a multiclass make-to-order/-stock M/G/1 queue [PDF]
, 2004 This paper develops a framework based on convex optimization and economic ideas to formulate and solve approximately a rich class of dynamic and stochastic resource allocation problems, fitting in a generic discrete-state multi-project restless bandit ...

The continuity heuristic: Temporal extrapolation in consumer judgment
Journal of Consumer Psychology, EarlyView.Abstract From choosing an established brand over a newcomer to deciding when to replace a product or commit to a subscription, consumers routinely make judgments about how much longer things will last. Across 24 studies (N = 9718), this research introduces and tests the continuity heuristic, an intuitive forecasting strategy in which consumers use how ...

Fluid limits for overloaded multiclass FIFO single-server queues with general abandonment
Stochastic Systems, 2013 We consider an overloaded multiclass nonidling first-in-first-outsingle-server queue with abandonment. The interarrival times, servicetimes, and deadline times are sequences of independent and identically,but generally distributed random variables.

Impact of Loss Synchronization on Reliable High Speed Networks: A Model Based Simulation
Journal of Computer Networks and Communications, 2014 Contemporary nature of network evolution demands for simulation models which are flexible, scalable, and easily implementable. In this paper, we propose a fluid based model for performance analysis of reliable high speed networks.

Fluid approximation analysis of a call center model with time-varying arrivals and after-call work
Operations Research Perspectives, 2015 Important features to be included in queueing-theoretic models of the call center operation are multiple servers, impatient customers, time-varying arrival process, and operator’s after-call work (ACW).

Limnology and Oceanography: Methods, EarlyView.Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.
