Повний текст джерелаAtt säkerställa och förbättra cybersäkerheten hos industriella styrsystem är av stor vikt för samhällssäkerheten. Det är känt att det förekommer sårbar-heter hos den här typen av system, som om de utnyttjas kan leda till allvarliga konsekvenser. Till exempel kan cyberattacker mot industriella styrsystem leda till storskaliga strömavbrott, dricksvattenbrist och störningar i olje- och gasproduktion. Av dessa skäl har de här problemen fått stor uppmärksamhet inom såväl forskningen som hos myndigheter och industrin. Den här avhandlingen motiveras främst av att de åtgärder som kan vidtas för att skydda industriella styrsystem ofta är kostsamma. I många fall är det därför inte möjligt att åtgärda alla sårbarheter som kan hittas hos systemen. Man behöver därför ta hänsyn till två problem. Till att börja med, hur man kan identifiera vilka sårbarheter, eller kombinationer av dessa, som det är mest kritiskt att förhindra angrepp mot. En viktig del av denna analys är att beräkna effekten av sådana angrepp. Detta problem behandlas i avhandlingens första del. Nästa problem är att fördela en budget för säkerhetsåtgärder för att förebygga de mest kritiska sårbarheterna, vilket behandlas i avhandlingens andra del. Avhandlingens första bidrag är ett ramverk för att bedöma effekten av angrepp mot industriella styrsystem. Här betraktar vi industriella styrsystem som både har till uppgift att reglera och att övervaka. För system med regler-uppgifter föreslår vi ett ramverk för att uppskatta effekterna av flera olika angreppsstrategier. Vi visar att beräkningen av effekten av samtliga strategier kan reduceras till att lösa en uppsättning konvexa minimeringsproblem. Eftersom lösningsalgoritmer för sådana problem är välkända så kan exakta värden enkelt beräknas. För industriella styrsystem med övervakningsuppgifter analyserar vi effekten av angrepp i form av injektion av bias. Vi bevisar attdenna effekt kan fås som lösningen till ett så kallat kvadratiskt programmeringsproblem med kvadratiska bivillkor, som går att lösa exakt på ett effektivt sätt. Vi demonstrerar resultaten i numeriska exempel. Avhandlingens andra bidrag är en flexibel modelleringsmetod för resurs-fördelning av säkerhetsåtgärder. Metoden vi föreslår är lämpad för dynamiska modeller av industriella styrsystem och löser resursfördelningsproblemet när antalet sårbarbeter och åtgärder är stort. Den föreslagna metoden kan effektivt identifiera de farligaste sårbarheterna i systemet. Sedan visar vi hur problemet med att eliminera dessa sårbarheter kan formuleras som en minimering av en linjär funktion med submodulära bivillkor. Detta innebär att man med garanterad prestanda kan hitta en sub otimal lösning med hjälp aven snabb så kallad girig algorithm. Vi demonstrerar att våra metoder går att tillämpa genom simuleringar av ett industriellt temperatur regleringssystem.

Повний текст джерелаDenna uppsats har undersökt vilken inverkan Solvens II kommer ha på svenska ömsesidiga livbolags tillgångssidor. Med hjälp av en kvantitativ analys och en kvalitativ undersökning av våra resultat har vi funnit att det kommer ske en betydande förändring i efterfrågan av vissa instrument. En stor ökning på efterfrågan av statsobligationer och ränteswappar med långa löptider är att vänta. Dessutom kommer både företags- och säkerställda obligationer vara betydligt mer attraktiva investeringsalternativ under det nya regelverket. En annan stor inverkan är den lägre riskjusterade avkastningen för aktier och aktierelaterade produkter. Över tid kommer detta sannolikt leda till en reduktion av svenska livbolags relativt höga exponering har gentemot aktier. Därutöver finner vi att bolagen har mycket att vinna på att införliva en optimering med avseende på de av regelverket angivna kapitalkraven.

Повний текст джерелаDen optimala tillgångsallokeringen är ett konstant aktuellt ämne. Den här uppsatsen ämnar undersöka effekten av riskviktning och målrisk på Sharpekvoten för en portfölj som handlar terminskontrakt på aktieindex och obligationer mellan 2000 och 2018. Dessutom undersöker denna uppsats på vilken nivå - instrument, tillgångsklass eller total portföljnivå - som en momentumstrategi har störst effekt. Vilket undersöks med statitisk försöksplanering. Det slutgiltiga resultatet i denna uppsats visar att riskviktning och målrisk förbättrar Sharpe-kvoten jämfört med en klassisk 60/40 kapitalallokering. Vidare är nyttjande av momentumstrategier det mest fördelaktiga på tillgångsklassnivå, det vill säga att allokera mellan aktieindex- och obligationsterminskontrakt.

Повний текст джерелаMuhammad, Khalid. "Longterm impact of anti-CD20 mediated transient B cell depletion on memory B cells in patients with rheumatoid arthritis." Doctoral thesis, kostenfrei, 2009. https://nbn-resolving.org/urn:nbn:de:bvb:20-opus-36319.
Повний текст джерелаDiverse roles of B cells in the pathophysiology of rheumatoid arthritis are now well established. B cells contribute to autoimmunity by producing autoantibodies, processing autoantigen and the production of different cytokines which are involved in the inflammatory cascade. Therefore approaches to target B lymphocytes directly or indirectly are developed for clinical practice to treat autoimmune diseases including rheumatoid arthritis. Transient B cell depletion by rituximab (anti-CD20 antibody) has gained prime importance in recent years. Meanwhile anti-CD20 mediated transient B cell depletion therapy is now used with clinical efficiency in the treatment of patients with rheumatoid arthritis. Rituximab induces noteworthy changes in the homeostasis of peripheral B cell subpopulations during the repletion phase with emerging immature B cells in peripheral blood followed by normalization of the naïve B cell pool and a longterm delay in memory B cell subsets in patients with rheumatoid arthritis. Particularly IgD+CD27+ memory B cells repopulate very slowly during B cell regeneration. In a prospective clinical study, our laboratory has shown that the overall number of memory B cells correlates well to the duration of clinical response to rituximab. Little is known about the particular molecular changes in the memory B cell repertoire after rituximab therapy. To better understand peripheral memory B cell subsets, we explored in detail the somatic mutational frequency and pattern of Ig-VH3 gene rearrangements by using a single B cell sorting technique followed by nested PCR before and up to 6 years after rituximab therapy in 18 RA patients. We compared rituximab inflicted dynamics of mutational acquisition to memory B cell repopulation in 4 healthy donors and 6 non RA patients undergoing high dose chemotherapy followed by autologous or allogeneic stem cell transplantation (SCT). Firstly we analyzed the peripheral composition of memory B cell subsets. The phenotypic analysis of peripheral pre-switch (IgD+CD27+) and post-switch (IgD-CD27+) memory B cells did not reveal any quantitative differences in RA patients prior to B cell depletion therapy compared to healthy donors. However extending those studies in directly analysing the B cell immunoglobulin receptor from individual B cells of RA patients and healthy controls brought interesting results. Pre-switched and post-switched memory B cells showed a highly significant difference in the amount of mutations/sequence. The population of IgD+CD27+ memory B cells is comprised of non-mutated, low and highly mutated (median= 9 mutations/ sequence) rearranged Ig receptors whereas the IgD-CD27+ memory B cell compartment shows quite uniformly highly mutated (median 18 mutations/ sequence) sequences indicating a significant difference between these two groups (mutational frequencies 3.83±0.19% vs. 7.1±0.53%; P=0.0001). Profound changes were noted in the re-emerging pre-switch memory B cells (IgD+/ CD27+) after transient B cell depletion with rituximab. These cells showed over a time period of 6 years after treatment with rituximab significantly delayed acquisition of mutations in Ig receptors on the single B cell level. One year after a single course of rituximab 84% of single repopulating IgD+/CD27+ B cells were unmutated and no highly mutated Ig-VH gene rearrangements were found(P=0.0001). Over time increasing numbers of mutations could be detected i-e 7.8% during 2nd year of regeneration (P=0.0001), 14% after 4 years (n=2). Nevertheless even 6 years after rituximab, VH mutations in IgD+ memory B cells were still reduced with 27% highly mutated sequences compared to 52% pre therapy(P=0.0001). Post-therapy analysis of CDR3 length of regenerated IgD+ memory B cells revealed increased CDR3 length which also correlates well with elevated number of non-mutated VH gene rearrangements observed during repletion phase. In comparison patients undergoing high dose chemotherapy followed by allogeneic stem cell transplantation repopulated IgD+ memory cells earlier with higher numbers of mutations in IgD+ memory B cells. One year after transplantation Ig receptors showed already 22% highly mutated and 42 % unmutated VH rearrangements. These findings indicated that anti-CD20 mediated B cell depletion seems not only to delay the production of pre-switch memory B cells but also significantly affects the acquisition of mutations in the IgD+ memory B cell pool. In contrary to the mutational pattern of IgD+ memory B cells after rituximab class switched memory B cells repopulate in the periphery with quantitatively normal mutations in their Ig receptors. Although the numeric replenishment of these recirculating class-switched memory B cells was also reduced after rituximab, we found no delay in quantitative acquisition of mutations also an increased proportion of IgA expressing B cells in this memory B cell subset was detected. Our data showed that post-therapy mutational targeting in RGYW/WRCY motifs were significantly increased as compared with that of pre-treatment (27% before rituximab vs. 43% after therapy, P=0.0003) indicating that affinity maturation may operate differently in class-switched memory B cells before and after B cell depletion. These results indicate a normal development process with an unimpaired mechanism of mutational acquisition in class-switched memory B cells. These data argue for different requirements to undergo somatic hypermutations in IgD+ memory B cells in comparison to class switched memory B cells. To conclude, our work has demonstrated for the first time a delayed acquisition of somatic hypermutations at single Ig receptor VH gene rearrangements of IgD+ memory B cells in comparison to class-switched memory B cells. These results demonstrate that IgD+ memory B cells are particularly susceptible to anti-CD20 treatment in patients with rheumatoid arthritis. In addition antigenic pressure and/or selection are substantially reduced by rituximab therapy which is basically not seen in the class-switched memory compartment. These data are in line with the hypothesis that IgD+ memory B cells have distinct requirements for activating their mutational machinery compared to class-switched memory B cells which recover normal mutations during regeneration phase. The results have implications in understanding the pathophysiology of memory B cell in rheumatoid arthritis and may be helpful in designing new targeted therapies

Повний текст джерелаThis thesis analyses the impact of residual interference of a CDMA system such as UMTS on the coverage and capacity of the network. The residual interference depends on the spreading code properties and also on the chosen receiver technique. Several complementary procedures are mounted in the system level in order to control the interference level: power control, admission control and resource allocation. The first part of the thesis is focused on the receiver techniques. Two receiver families are studied and compared in terms of performance: the correlation receivers (RAKE receiver) and the multiuser bloc linear receivers. Different approaches for performance evaluation of the receivers are analysed and compared: exact calculus, approximate calculus based either on the gaussian model of interference or approximate based on the development of the mean error probability in Taylor series and the asymptotic evaluation for systems with great spreading factors. The complexity of implementation of the receiver has also been considered. We proposed a linear bloc-sub-optimal receiver based on splitting the processing in sub blocs. The tradeoff between complexity and performances of such a receiver has been optimised. In order to evaluate the impact of the receiver choice on the other procedures mounted in the system level, the second part is focused on the analysis of the interference at the output of a RAKE receiver or a bloc linear receiver. The goodness of the gaussian model, which presents a lot of advantages, has been discussed. The interference model has been taken into consideration with different level of simplifications and introduced in some system study examples: call admission and code allocation, power allocation, and the resulting tradeoff between coverage and capacity

Повний текст джерелаBecause of the current global biodiversity decline, understanding the consequences of each threat on biodiversity is crucial for conservation biology. Invasive species are among the main threats at the global scale, and can locally imply harmful damages on ecosystems. Studying the phenomena driving the effects and potential for expansion of these species appears as a crucial element to assess their long terms impacts. In this study, we focused our efforts on an invasive population of the African clawed frog, Xenopus laevis, in France, to bring insight about the interactions of this population with its environment and to study the changes in resource allocation to the life history traits, related to reproduction, survival and dispersal probabilities, during the range expansion of the population. We studied the diet in the French invasive population and in other invasive and native populations, and found that this species can expand by predating a narrow, as well as a broad, range of prey categories. We also detected an impact of X. laevis on the native amphibian community in France. In the second section of the thesis, we reported a decrease in reproductive investment, and an increased dispersal allocation of resources at the range edge. We finally studied population dynamics and detected a lower survival probability and density at the range core. All these results combined suggest that the potential for long term impacts is important in France for X. laevis as well as in other areas where the species has been, or will be, introduced
