PURPOSE We aimed to explore the value of localizing small ground-glass nodules (GGNs; <10 mm) or multiple GGNs within the same lobe in re-aerated lung specimens using CT-guided fine-needle localization. METHODS Thirty-five lung specimens containing single small GGNs (<10 mm) and eight specimens containing two or more GGNs in the same lobe were re-aerated with an inflatable aerator. All lesion...

This paper presents a novel multi-objective genetic algorithm (MOGA) based on the NSGA-II algorithm, which uses metamodels to determine optimal sampling locations for installing pressure loggers in a water distribution system (WDS) when parameter uncertainty is considered. The new algorithm combines the multi-objective genetic algorithm with adaptive neural networks (MOGA–ANN) to locate pressur...

BACKGROUND To ensure sustainable routine surveillance of mosquito vectors, simple, effective and ethically acceptable tools are required. As a part of that, we evaluated the efficiency of resting boxes baited with fresh and aging cattle urine for indoor and outdoor sampling of An. arabiensis in the lower Moshi rice irrigation schemes. METHODS A cattle urine treatment and re-treatment schedule...

We present a novel approach for 3D hand motion tracking of stage characteristics as observed in cognitive psychology. A Hidden Markov Model acquired in humancomputer interaction is used to represent the high-level structure of gestures reduce the dimensionality of the search space. The estimation of hand gestures is handled by combing the model and particle filter. The sampling is introduced PE...

Exact simulation approaches for a class of diffusion bridges have recently been proposed based on rejection sampling techniques. The existing rejection sampling methods may not be practical due to small acceptance probabilities. This paper proposes an adaptive approach which improves the existing methods significantly under certain scenarios. The idea of the new method is based on a layered pro...

| Our goal in this paper is to set a theoretical basis for the comparison of re-sampling and interpolation methods. We consider the general problem of the approximation of an arbitrary continuously-deened function f(x) |not necessarily bandlimited| when we vary the sampling step T. We present an accurate L 2 computation of the induced approximation error as a function of T for a general class o...

The use of adaptive designs in conjoint analysis has been shown to lead to an endogeneity bias in part-worth estimates using sampling experiments. In this paper, we re-examine the endogeneity issue in light of the likelihood principle. The likelihood principle asserts that all relevant information in the data about model parameters is contained in the likelihood function. We show that adhering ...

Abstract 7 Long sampling tubes are often required for particle measurements in street 8 canyons. This may lead to significant losses of the number of ultrafine (those below 9 100 nm) particles within the sampling tubes. Inappropriate treatment of these losses 10 may significantly change the measured particle number distributions (PND), because 11 most of the ambient particles, by number, exist ...

Objective: The aim of the present study was to determine the effect of "Community Re-entry Program" (CRM) on psychological condition in the patients with schizophrenia. Materials & Methods: In this quasi experimental design study that sampling was performed available and none randomized. 24 patients with schizophrenia who had the inclusion criteria selected and were placed into two intervent...

In recent years, online social networks (OSN) have emerged as a platform of sharing variety of information about people, and their interests, activities, events and news from real worlds. Due to the large scale and access limitations (e.g., privacy policies) of online social network services such as Facebook and Twitter, it is difficult to access the whole public network in a limited amount of ...
