A simple model is presented as an aid in understanding, first, the relative noise performance and, second, the noise reduction achievable by referencing, in different experimental approaches to single shot broadband coherent anti-Stokes Raman scattering (CARS). Qualitative agreement is obtained with previous experimental investigations of CARS noise. The broadband dye laser radiation is described

Popular Abstract in Swedish Leukemi, "det vita blodet", var ursprungligen en beskrivande diagnos på tillstånd där leukocyter (vita blodkroppar), eller snarare deras maligna, d.v.s. canceromvandlade former, tillväxte i sådan grad att de trängde undan andra blodbildande celler. I en sådan situation drabbas patienterna av blodbrist, infektioner och blödningar. Med tiden har vi lärt oss särskilja olikIn the present thesis, clinicogenetic correlations are investigated in a large population-based series of acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), acute lymphoblastic leukemia, and chronic myeloid leukemia, for which the karyotypes were analyzed at the same center. The karyotypic pattern, i.e. normal karyotype or 1, 2 or ³3 anomalies, does not differ between males and female

Popular Abstract in Swedish Som titeln antyder behandlar avhandlingen titrerande polyelektrolyter, d.v.s. stora molekyler med många syra-basgrupper. Sådana molekyler kan vi finna lite överallt, ja till och med i våra kroppar, som innehåller en mängd olika polyelektrolyter. Deras egenskaper kan variera starkt beroende på omständigheterna och har många biologiska och industriella tillämpningar. Att Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. Sampling is facilitated for the latter two by the use of pivot

Popular Abstract in Swedish Många grundläggande processer i naturen involverar transport av energi från ett ställe till ett annat. Ett exempel på detta är fotosyntesen där solljus fångas upp av molekylkomplex, för att sedan transporteras till ett reaktionscenter. I reaktionscentret byggs den laddning upp som sedan används för att framställa växtmassa. För att minimera energiförlusten i den här typAn efficient transfer of energy in molecular systems has proven to be of fundamental importance both in nature and industrial applications. The ability of molecules to work together forming collective excitations, so-called excitons, plays a key role in for example the extraordinary fast energy transfer involved in the first steps of photosynthesis. The characterization of excitonic states in conj

Background. When delivering an embedded product, such as a mobile phone, third party products, like games, are often bundled with it in the form of Java MIDlets. To verify the compatibility be- tween the runtime platform and the MIDlet is a labour-intensive task, if input data should be manually generated for thousands of MIDlets. Aim. In order to make the verification more efficient, we investiga

Less than a decade has elapsed since the publication in 2000 of the first anthology devoted to lipocalins (Biochim Biophys Acta 1482, 2000), and only a few years since the first Lipocalin International Symposium in Copenhagen in 2003 (Benzon Symposium no. 50 “The Lipocalin Protein Superfamily,” Copenhagen, 2003) and the introduction of a public lipocalin website (http://www.jenner.ac.uk/lipocalins

There is today a need of better prediction of part geometry regarding industrial products by simulations. There is a need for better prediction of material inflow, stresses and strains and final geometry. One way to solve this could be by using a more advanced friction model. Today a zero order friction model (Coulomb friction) is normally used. By using a friction model of higher order the fricti
