In this paper, I consider theoretical models of the decay via photobleaching of a sample of surface-immobilized fluorescent molecules excited by a spatially varying laser intensity profile. I show that, with mild restrictions on the photobleaching mechanism, the fluorescence decay measured in a nonuniform excitation profile is always nonexponential. Under the same conditions, the fluorescence d...

The concept of Fuzzy-random-variable was introduced as an analogous notion to randomvariable in order to extend statistical analysis to situations when the outcomes of some random experiment are fuzzy sets. But in contrary to the classical statistical methods no unique definition has been established yet. In this paper a set-theoretical concept of fuzzy-random-variable will be presented. This n...

The paper conceptualizes ways to approach meaning, purpose, and components of tools to measure the digital divide. Three arguments are raised in this paper. First, I raise criticism of policymakers who prefer to approach the digital divide from a cost and rapid outputs perspectives, at the expense of a thoughtful analysis of: (i) the purpose of the tool, (ii) the level of observation, and (iii)...

This essay explores a conceptual definition of psychological processes. Previous researchers from the fields of psychology and neuroscience have noted that improving the definition of psychological processes may be extremely useful to help current efforts to map the neurobiological basis of psychological phenomena. in this essay i suggest a conceptual path in which psychological processes might...

This conceptual paper introduces the Theory of Dialogical Self to the career development literature. The life themes component of the Theory of Career Construction is the focus of application for dialogical self. It is proposed that the notion of dialogical self may contribute to understanding how individuals construct the career-related life themes. Dialogical self is thus presented as a promi...

We report the discovery of a new smectic-C{*} liquid-crystal phase with six-layer periodicity by resonant x-ray diffraction. Upon cooling, the new phase appears between the SmC{alpha}{*} phase having a helical structure and the SmC{d4}{*} phase with four-layer periodicity. This SmC{d6}{*} phase was identified in two mixtures which have an unusual reversed SmC{d4}{*}-SmC{*} phase sequence. The S...

T treatise on the study of cross-cultural differences between modern societies starts with an examination of the various ways in which culture has been conceptualized. Approaches to the concept and study of culture have varied between academic disciplines, and sometimes even within them. The goal of this analysis is not to provide one right perspective. Culture can be whatever a scholar decides...

Close relationships play a vital role in human health, but much remains to be learned about specific mechanisms of action and potential avenues for intervention. This article provides an evaluation of research on close relationships processes relevant to health, drawing on themes from major relationship science theories to present a broad conceptual framework for understanding the interpersonal...

The complex molecular networks in the cell can give rise to surprising interactions: gene deletions that are synthetically lethal, gene overexpressions that promote stemness or differentiation, synergistic drug interactions that heighten potency. Yet, the number of actual interactions is dwarfed by the number of potential interactions, and discovering them remains a major problem. Pooled screen...
