The present study investigated and analyzed the clinical impact of sublobectomy on pulmonary functions.Changes in pulmonary function before and after sublobectomy were compared to the changes after lobectomy.Changes in the pulmonary function before and after sublobectomy and lobectomy did not exhibit remarkable differences in long-term effects. Surgery-related indexes of the sublobectomy group ...

Based on social network perspective, we developed a model about the knowledge sharing of communities of practice (CoPs), analyzed the knowledge sharing of CoPs from the view of the network density, network centrality, network structure. And we found out that only the above indexes are kept in appropriately level can stimulate the knowledge sharing in CoPs. The strong ties contribute to the tran...

For many graphs parameters, criticality is a fundamental issue. For domination number, Brigham, Chinn, and Dutton began the study of graphs where the domination number decreases on the removal of any vertex. Brigham, Haynes, Henning, and Rall defined the term (γ, k)-critical and proved results for graphs that are (γ, 2)-critical or bicritical. A graph G is said to be (γ, k)-critical if γ(G − S)...

Spent fuel transportation and storage cask designs based on a burnup credit approach must consider issues that are not relevant in casks designed under a fresh-fuel loading assumption. For example, the spent fuel composition must be adequately characterized and the criticality analysis model can be complicated by the need to consider axial burnup variations. Parametric analyses are needed to ch...

An increasing trend in embedded system design is to integrate components with different levels of criticality into a shared hardware platform for better cost and power efficiency. Such mixed-criticality systems are subject to certifications at different levels of rigorousness, for validating the correctness of different subsystems on various confidence levels. The realtime scheduling of certifi...

A secure index is a data structure that allows a querier with a " trapdoor " for a word x to test in O(1) time only if the index contains x; The index reveals no information about its contents without valid trapdoors, and trapdoors can only be generated with a secret key. Secure indexes are a natural extension of the problem of constructing data structures with privacy guarantees such as those ...

background: to evaluate the situation in a district demographic and health indexes are of great  importance. the aim of this article is to analyze some demographic and health indexes in chadegan district during 2004-2009. methods: this was a descriptive study and the target population was the population of chadegan district from 2004-2009. data collection was done according to registered data i...

This paper combines the CRSP market index with multiple factors to create a single multifactor index. Empirical tests of different indexes indicate that: (1) Sharpe ratios substantially increase and GRS test statistics decrease as multifactors are incrementally added index; (2) resultant significantly priced in cross-sectional associated beta loadings t-values exceeding 3.0 most cases.

A non-Abelian and stochastic self organized criticality model has been proposed in which each avalanche contains one stochastic site and all remaining sites in the avalanche are deterministic. Studies of avalanche structures, waves and size moments showed the shell-like avalanche structures, correlated waves within avalanches and complex size moments. We may assert that the model shows multifra...
