Shot noise of coupled semiconductor quantum dots

The low-frequency shot noise properties of two electrostatically coupled semiconductor quantum dot states which are connected to emitter/collector contacts are studied. A master equation approach is used to analyze the bias voltage dependence of the Fano factor as a measure of temporal correlations in tunneling current caused by Pauli’s exclusion principle and the Coulomb interaction. In particula

Does vitamin d intake during infancy promote the development of atopic allergy?

The active metabolite of vitamin D, 1,25-(OH)2D3, has immunomodulatory properties in addition to its more established action on bone and calcium metabolism. Recently vitamin D has been proposed as one of several environmental factors responsible for the increase in atopic diseases during the last decades. The objective of this study was to determine whether the estimated dose of dietary vitamin D3

Popular Abstract in Swedish I Ärlighetseffekten. Den litterära självbiografin sedd genom pressen. Fallet La Force des choses av Simone de Beauvoir undersöks den litterära självbiografin som genre sedd genom receptionen i pressen av den tredje delen av Simone de Beauvoirs självbiografi La Force des choses vid utgivningen i Frankrike 1963. Studien innehåller tre huvuddelar som tar upp kommentarerna In light of autobiographical theory, this study deals with the critics' reception of Simone de Beauvoir's La Force des choses when the book was first published in 1963 in France. The three main parts examine the critical comments on the genre, the final controversial words expressing the author's disappointment, and the evaluation of her style. For the latter, Morten Nøjgaard's theory of literary

aroma - An R object-oriented microarray analysis environment

We have implemented a self-contained package for DNA microarray analysis in R. The package is named aroma and is formerly known as com.braju.sma. The purpose of the package is to provide end-users with easy access to the latest statistical tools and methods, to provide other statisticians with a structured platform to develop and test new analysis methods, and to make our methods available to an a

Numerical Simulations for Studies of Unsteady Combustion in Practical Combustion Devices

A major problem in the design of combustion equipment is to prevent the occurrence of combustion instabilities. Combustion instabilities appear as periodic oscillations in pressure and heat release through a feedback mechanism between the fluid dynamics and the combustion process. These oscillations may induce e.g. mechanical vibrations and increased heat transfer, leading to poor performance or e

The Relationships between Sex Hormones and Sexual Function in Middle-Aged and Older European Men.

Context: Limited data are available exploring the associations between sex hormones, multiple domains of sexual functioning, and sexual function-related distress in nonpatient samples in Europe. Objectives: The aim of the study was to investigate the relationships between serum testosterone (T), estradiol (E2), and dihydrotestosterone (DHT) and sexual function in a multicenter population-based stu

Canonical bases for subalgebras of factor algebras

We introduce canonical bases for subalgebras of quotients of the commutative and non-commutative polynomial ring. The usual theory for Gröbner bases and its counterpart for subalgebras of polynomial rings, also called SAGBI bases, are combined to obtain a tool for computation in subalgebras of factor algebras.
