A new method for calculating average molecular weights is presented nonlinear polymers. In contrast to the previous methods of Flory and Stockmayer which first calculate distribution all species then use distributions properties, calculates these properties directly. Gordon, probability generating functions are not required. Starting with elementary utilizing recursive nature network polymers property relations can be developed more simply. We illustrate calculations Mw Mz, gel point a wide...

We present a randomization procedure for computing transient solutions to discrete state space, continuous time Markov processes. This computes probabilities. It is based on construction relating process chain. Modifications and extensions of the method allow computation distributions first passage times sojourn in processes, also expected cumulative occupancy number events occurring during interval. Several implementations are discussed. In particular we an implementation general class...
Work by D.E. Eckhardt and L.D. Lee (1985), shows that independently developed program versions fail dependently. The authors show there is a precise duality between input choice in this model consider generalization which different can be using diverse methodologies. use of methodologies shown to decrease the probability simultaneous failure several versions. Indeed, it theoretically possible obtain exhibit better than independent behavior. formalize notion methodological diversity...
Failure times of a software reliability growth process are modeled as order statistics independent, nonidentically distributed exponential random variables. The Jelinsky-Moranda, Goel-Okumoto, Littlewood, Musa-Okumoto logarithmic, and power law models all special cases statistic models, but there many additional examples well. Various characterizations, properties, this class developed presented.
We show that (i) Brownian motion conditioned to be positive is meander; (ii) tied-down meander excursion; and (iii) bridge excursion. Using these results we derive the distribution of suprema
PURPOSE Oral mucositis (OM) remains a common, debilitating toxicity of radiation therapy (RT) for head and neck cancer. The goal this phase IIb, multi-institutional, randomized, double-blind trial was to compare the efficacy safety GC4419, superoxide dismutase mimetic, with placebo reduce duration, incidence, severity severe OM (SOM). PATIENTS AND METHODS A total 223 patients (from 44 institutions) locally advanced oral cavity or oropharynx cancer planned be treated definitive postoperative...
Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status financial performance relative aspirations affect firm risk behavior. The finds that CEOs tend pay smaller for target firms, but these tendencies change when prior deviates from the industry average returns, thereby leading higher premiums. also be even larger have more recently attained status. Taken together, findings contribute literatures by suggesting...
Recursive computational formulas for the steady-state distributions of exponential single-server (preemptive and nonpreemptive) priority queues with two classes customers are derived using Neuts’ theory matrix-geometric invariant probability vectors.
Abstract Our recursive method is extended to calculate several new parameters for stepwise polyfunctional polymerization. In the pregel region we weight average molecular weight, M w , polydisperse reactants and effective functionality, f e of a reacting mixture. These quantities are useful systems employing reactive oligomers. We also number branches per molecule, B longest chain. should be viscosity relations. postgel give relations extent reaction in soluble fraction. This result can used...

Abstract A model of a two-echelon (two levels repair, one level supply) repairable-item provisioning system is presented. It desired to find the capacities base and depot repair facilities as well spares which together guarantee specified service at minimum cost.

Feller (1966) claims that a regenerative stochastic process with non-lattice interarrival-time distribution has limiting distribution. This is true if (i) the class of distributions restricted, or (ii) regularity conditions are imposed on sample paths process.
Manganese exposure produces Parkinson9s-like neurologic symptoms, suggesting a selective dysregulation of dopamine transmission. It is unknown, however, how manganese accumulates in dopaminergic brain regions or it regulates the activity neurons.

During aging humans lose midbrain dopamine neurons, but not all regions exhibit vulnerability to neurodegeneration. Microglia maintain tissue homeostasis and neuronal support, microglia become senescent likely some of their functional abilities. Since is the greatest risk factor for Parkinson's disease, we hypothesized that aging-related changes in neurons occur vulnerable substantia nigra pars compacta (SNc) ventral tegmental area (VTA).

Background: EUS-guided gastroenterostomy (EUS-GE) is a minimally invasive therapy for the management of gastric outlet obstruction (GOO). EUS-GE has demonstrated excellent short-term efficacy without risks surgical bypass. However, there limited data on follow-up outcomes. In this study, we collected 6-month patients who underwent benign and malignant etiologies, to aim show shift in paradigm their algorithm. Methods: This was retrospective multicenter study across 7 international centers...
