E-mail address: [email protected] The residence time of a diffusing particle in a prescribed spatial region recently finds an increasing number of applications in physics and chemistry. A partial differential equation for the residence time moments is derived, as a generalization of the ...

We proposed in a previous paper [Opt. Commun. 228, 33 (2003)] a modified radiative transfer equation to describe radiative transfer in a medium with a spatially varying refractive index. The present paper is devoted to the demonstration that this equation perfectly works in the non-absorbing / non-scattering limit, what was contested by L. Martí-López and coworkers [Opt. Commun. 266, 44 (2006)]...

We consider the control of a production facility consisting of a single workstation with multiple failure modes and part types using a continuous flow control model. Technical issues concerning the convexity and differentiability of the differential cost function are investigated. It is proven that under an optimal control policy the differential cost is C1 on attractive control switching bound...

Few studies have examined how e-business processes can be leveraged to create business value. By examining the technical, relational and business components of an e-business process, we propose a three-layer structure to identify the source of e-business value in procurement, channel management, and customer service processes. We tested research model using structural equation modeling with dat...

This paper studies the transfer of tacit and explicit knowledge from foreign parents to international joint ventures (IJVs) and the impact of these two types of knowledge transfers on the performance of young and mature IJVs. We estimate a structural equation model using survey data from 334 Korean joint ventures and find support for our hypotheses regarding IJV age, knowledge transfers, and pe...

6 In this study, a total of 370 rice samples collected from six provinces in China were 7 surveyed for the presence of aflatoxins (AFs) and ochratoxin A (OTA) using 8 dispersive liquid-liquid microextraction coupled to liquid chromatography with 9 fluorescence detection. The results obtained in this survey showed that 63.5% 10 (235/370) and 4.9% (18/370) of rice samples contained detectable amo...

Based on gathered survey data from Chinese apparel exporters, using structural equation modeling technique, a proposed firm’s export market oriented (EMO) behavior model was empirically tested. A great set of antecedent factors (i.e., organizational structure, export systems, export coordination, top management factors, and export dependence) and moderating factors (i.e., environmental turbulen...
