In this paper we treat the solvability of a general problem of linear electromagnetics. More precisely, we study the propagation (in the time domain) of electromagnetic fields in a bianisotropic medium, which presents dispersion. This is modeled by linear constitutive relations containing convolution terms. So the problem is represented by an integrodifferential equation in some appropriate Hilber
High throughput in particle and molecular sorting schemes is an important performance indicator and can be realized through increased volumetric processing rates or increased concentrations. Here we investigate the effect of increased concentration of high-molecular weight DNA in micropillar arrays for deterministic lateral displacement (DLD). We find that the array imposes regular fluctuations in
This thesis aims to examine how university-educated members of Generation Z in Sweden explain their decision to delay parenthood. As declining fertility rates across the globe risk to strain the global economy, this topic has never been more relevant. Sweden and the Noridcs have served as examples on which other nations have based their fertility strategies, but as the region has seen a sudden, an
Flooding of coastal infrastructure due to rising sea levels and storm surges can be mitigated by coastal protection. The design of such infrastructure depends not only on the storm surge still-water level but also strongly on storm-wave characteristics. Therefore, numerical wave modelling is essential in the absence of wave observations. Fetch-limited seas with low moderate wave-energy climates ar
Popular Abstract in Swedish Avhandlingen innehåller ett inledningskapitel följt av fyra separata studier. Studierna behandlar olika aspekter av humankapital, begåvning och immigration. I den första studien, Ability and Rates of Return to Schooling ? making use of the Swedish Enlistment Battery Test, används det svenska mönstringstestet för att skatta avkastningen på utbildningen för individer medThis thesis consists of an introductory chapter followed by four separate papers. The papers deal with various aspects of human capital, ability and migration. Using the Swedish Military Enlistment test, the first paper, Ability and Rates of Return to Schooling ? making use of the Swedish Enlistment Battery Test, estimates the return to schooling for individuals belonging to different parts of th

Denna studie genomfördes i Sverige med syftet att erbjuda ett nytt perspektiv på ämnet turnover och hur olika faktorer påverkar beslutet att säga upp sig från jobbet eller stanna kvar. Med detta syfte undersökte studien de sex faktorerna lön och förmåner, miljö, karriärmöjligheter, kollegiala aspekter, meningsfullhet och balans mellan arbete och privatliv, som har ansetts vara några av de mest infThis study was conducted in Sweden with the motivation to provide a new perspective on the topic of turnover, specifically how different factors may affect turnover decision making. With this aim, the study examined the six factors salary and benefits, environment, career opportunities, collegial aspects, meaningfulness, and work/life balance, that have been regarded as some of the most influentia
A search for pair-produced third generation scalar leptoquarks is presented, using proton-proton collisions at root s = 7 TeV at the LHC. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 4.7 fb(-1). Each leptoquark is assumed to decay to a tau lepton and a b-quark with a branching fraction equal to 100%. No statistically significant excess above the Stan
We report a search for first generation scalar leptoquarks using 1.03 fb(-1) of proton-proton collisions data produced by the Large Hadron Collider at root s = 7 TeV and recorded by the ATLAS experiment. Leptoquarks are sought via their decay into an electron or neutrino and a quark, producing events with two oppositely charged electrons and at least two jets, or events with an electron, missing t
The results of a search for the production of second generation scalar leptoquarks are presented for final states consisting of either two muons and at least two jets or a muon plus missing transverse momentum and at least two jets. A total of 1.03 fb(-1) integrated luminosity of proton-proton collision data produced by the Large Hadron Collider at root s = 7 TeV and recorded by the ATLAS detector
Deprotonation of the ionogenic tetradentate ligand 6,6'-bis(1H-tetrazol-5-yl)-2,2'-bipyridine [H2bipy(ttr)2] in the presence of Fe(II) in solution has afforded an anionic mononuclear complex and a neutral two-dimensional coordination polymer formulated as, respectively, NEt3H{Fe[bipy(ttr)2][Hbipy(ttr)2]}·3MeOH (1) and {Fe[bipy(ttr)2]}n (2). The anions [Hbipy(ttr)2](-) and [bipy(ttr)2](2-) embrace
We demonstrate transport spectroscopy on bottom-up grown few-electron quantum dots in semiconductor nanowires. The dots are defined by InP double barrier heterostructures in InAs nanowires catalytically grown from nanoparticles. By changing the dot size, we can design devices ranging from single-electron transistors to few-electron quantum dots. In the latter case, electrons can be added one by on
We demonstrate high contrast quantum interference between one-photon and three-photon absorption pathways in an organic solid at room temperature. Illumination of a thin polymer film activated with fluorescing dendrimer chromophores of large three photon absorption cross section with two simultaneous femtosecond pulses at near-IR frequency. and its third harmonic UV frequency 3. results in a spati
InP quantum dots grown on GaInP by the Stranski-Krastanow technique are less well studied than InAs quantum dots grown on GaAs. We here give a review of the main experimental evidence for the InP dots being charged when grown in between n-type barriers.
In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. This architecture implies that quantum computers are especially suited to simulate quantum systems that are otherwise difficult to compute. In this work, the excitation and
