Event Generators

A brief overview of the current state of general purpose event generators, focusing on recent developments in extending the precision of QCD to next-to-leading order.

Dynamical diophantine approximation

Let $mu$ be a Gibbs measure of the doubling map $T$ of the circle. For a $mu$-generic point $x$ and a given sequence ${r_n} subset R^+$, consider the intervals $(T^nx - r_n pmod 1, T^nx + r_n pmod 1)$. In analogy to the classical Dvoretzky covering of the circle we study the covering properties of this sequence of intervals. This study is closely related to the local entropy function of the Gibbs

Objects of attention

The starting-point of this talk is the question which are the objects of attention? The answer simply is that there are no objects of attention as such, i.e., no generic objects of attention. Instead several kinds of object of attention can be discerned troughout the attention process. Which kind will constitute the actual object of attention in a certain situation depends on the task that the sub

Electron Transport in Quantum Dots Defined in Low-Dimensional Semiconductor Structures

Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

Abstract in Italian Negli ultimi trent’anni il sindacato ha iniziato a perdere valenza sotto il profilo nazionale, questo soprattutto a causa del declino degli iscritti a tali organizzazioni. Declino che ha interessato, bene o male, tutti i paesi occidentali, dall’Europa agli Stati Uniti d’America. Ciononostante (o proprio per questo), gli studiosi delle relazioni industriali e della sociologia de
