Application of the IS-MP-IA model to the German economy and policy implications
No full textExtending the IS-MP-IA model developed by Romer (2000) and applying the GARCH (Engle, 1982, 2001) methodology, the author finds that equilibrium GDP in Germany is positively affected by stock market performance and real exchange rate appreciation, and negatively influenced by the expected inflation rate, the government deficit/GDP ratio, and the U.S. federal funds rate. The relatively low deficit/GDP ratio of 1.83% in 2003 indicates that its fiscal condition was healthy. However, some other EU members may need to exercise fiscal discipline. Because real appreciation has a positive impact on output, a stronger euro may not be a concern for Germany but may be worried by those EU member nations which depend upon exports to stimulate their economies.
Winning redefined, a new brand positioning for MP Motorsport
No full textMP Motorsport is a talent educating race team participating in the classes below the Formula 1. The problem with the lower classes and therefore MP Motorsport as well is that these classes don’t get much attention and exposure. As a company run by people with passion the branding and positioning is more something that naturally emerged from this passion rather than a series of conscious decisions. This makes it fragile. A more conscious strategy and vision on how MP Motorsport needs to be branded and positioned against their competition that is more than “look how cool racing is” is needed to become more attractive for sponsoring. This report describes the process from analysis to finding the right positioning and an advise for a new brand identity and an implementation plan to help becoming more attractive for sponsoring goals. The analysis done with employees showed a unique characteristic that will help the team to position themselves against the competition; the family atmosphere. This atmosphere is what also characterises their contradictory personality. This personality is on one hand leading and ambitious and on the other hand modest and involved. Competition and stakeholder analysis have been performed to find the right combination of being unique to the competition, desirable for the stakeholders (the fans and sponsors) and builds upon the core strengths of the company. Then using the brand key model, a positioning is made with the essence: Be your best self. The belief, “in everyone hides a talent” and values like “everyone is equal” and “together we succeed” combined with the essence and the positioning resulted in a brand story that describes the feeling MP Motorsport wants to communicate. To manifestate the brand, an advise has been set up for a tone of voice and tone of image. Wrapped in a concept called “winning redefined” this advise is part of the whole implementation plan that should lead the way for the team to implement the newly created brand in short and long term actions. In 3 phases MP Motorsport is advised to start with a clear brand introduction to the target groups Gen Z and potential sponsors. The next phase revolves around creating a community to attract both Gen Z talents and subsequently sponsors to interact with the team and each other. Finally the last phase is long term focused and aims for sustainable growth. In this phase the community is established and can expect various opportunities to discover and develop a whole range of talents, sponsors and gen z are connected to each other via MP Motorsport and the team is able to finance the lower classes without the pressure of the money drivers bring along.Strategic Product Desig
Derivations (MP) and Evaluations (OT)
No full textThe main claim of this paper is that the minimalist framework and optimality theory adopt more or less the same architecture of grammar: both assume that a generator defines a set S of potentially well-formed expressions that can be generated on the basis of a given input, and that there is an evaluator that selects the expressions from S that are actually grammatical in a given language L. The paper therefore proposes a model of grammar in which the strengths of the two frameworks are combined: more specifically, it is argued that the computational system of human language CHL from MP creates a set S of potentially well-formed expressions, and that these are subsequently evaluated in an optimality theoretic fashion.The definitive version of this paper is published in Linguistics in Potsdam 25 (2006).Broekhuis, H.

An Endoribonuclease Functionally Linked to Perinuclear mRNP Quality Control Associates with the Nuclear Pore Complexes
No full textNuclear mRNA export is a crucial step in eukaryotic gene expression, which is in yeast coupled to cotranscriptional messenger ribonucleoprotein particle ( mRNP) assembly and surveillance. Several surveillance systems that monitor nuclear mRNP biogenesis and export have been described, but the mechanism by which the improper mRNPs are recognized and eliminated remains poorly understood. Here we report that the conserved PIN domain protein Swt1 is an RNA endonuclease that participates in quality control of nuclear mRNPs and can associate with the nuclear pore complex (NPC). Swt1 showed endoribonuclease activity in vitro that was inhibited by a point mutation in the predicted catalytic site. Swt1 lacked clear sequence specificity but showed a strong preference for single-stranded regions. Genetic interactions were found between Swt1 and the THO/TREX and TREX-2 complexes, and with components of the perinuclear mRNP surveillance system, Mlp1, Nup60, and Esc1. Inhibition of the nuclease activity of Swt1 increased the levels and cytoplasmic leakage of unspliced aberrant pre-mRNA, and induced robust nuclear poly(A)(+) RNA accumulation in mlp1 Delta and esc1 Delta strains. Overexpression of Swt1 also caused strong nuclear poly(A)(+) RNA accumulation. Swt1 is normally distributed throughout the nucleus and cytoplasm but becomes concentrated at nuclear pore complexes (NPCs) in the nup133 Delta mutant, which causes NPC clustering and defects in mRNP export. The data suggest that Swt1 endoribonuclease might be transiently recruited to NPCs to initiate the degradation of defective pre-mRNPs or mRNPs trapped at nuclear periphery in order to avoid their cytoplasmic export and translation.</p

A novel approach to MP-PIC: Continuum particle model for dense particle flows in fluidized beds
No full textA novel approach to Multiphase-Particle-in-Cell (MP-PIC), called Continuum Particle Model (CPM), is developed for dense gas-particle flows. CPM has high computational speed, comparable to that of MP-PIC, but a robustness and accuracy closer to that of a Discrete Element Model (DEM). The gas phase is treated as a continuum phase and particles are tracked discretely, but particle collisions are modelled by considering the divergence of the continuum particle stress tensor. Details on efficient solution to the model are presented. For comparison, a parametric study is performed for quasi-2D fluidized beds. Comparison of CFD-CPM is made with MP-PIC and CFD-DEM. The particle stress models by Harris and Crighton, and by Srivastava and Sundaresan are tested in our CFD-CPM. Results from CFD-CPM based on the Srivastava and Sundaresan particle stress model show good agreement with CFD-DEM results. We validate our model by comparison with experimental benchmark results from Gopalan et. al. (2016).Complex Fluid Processin
The role of interleukin 12 and nitric oxide in the development of spontaneous autoimmune disease in MRL/MP-lpr/lpr mice
No full textMRL/MP-lpr/lpr (MRL/lpr) mice develop a spontaneous autoimmune disease. Serum from these mice contained significantly higher concentrations of nitrite/nitrate than serum from age-matched control MRL/MP-+/+ (MRL/+), BALB/c or CBA/6J mice. Spleen and peritoneal cells from MRL/lpr mice also produced significantly more nitric oxide (NO) than those from the control mice when cultured with interferon (IFN) gamma and lipopolysaccharide (LPS) in vitro. It is interesting to note that peritoneal cells from MRL/lpr mice also produced markedly higher concentrations of interleukin (IL) 12 than those from MRL/+ or BALB/c mice when cultured with same stimuli. It is striking that cells from MRL/lpr mice produced high concentrations of NO when cultured cells from MRL/+ or BALB/c mice. The enhanced NO synthesis induced by IFN- gamma/LPS was substantially inhibited by anti-IL-12 antibody. In addition, IL-12-induced NO production can also be markedly inhibited by anti-IFN-gamma antibody, but only weakly inhibited by anti-tumor necrosis factor alpha antibody. The effect of IL-12 on NO production was dependent on the presence of natural killer and possibly T cells. Serum from MRL/lpr mice contained significantly higher concentrations of IL-12 compared with those of MRL/+ or BALB/c control mice. Daily injection of recombinant IL-12 led to increased serum levels of IFN- gamma and NO metabolites, and accelerated glomerulonephritis in the young MRL/lpr mice (but not in the MRL/+ mice) compared with controls injected with phosphate-buffered saline alone. These data, together with previous finding that NO synthase inhibitors can ameliorate autoimmune disease in MRL/lpr mice, suggest that high capacity of such mice to produce IL-12 and their greater responsiveness to IL-12, leading to the production of high concentrations of NO, are important factors in this spontaneous model of autoimmune disease
Protein synthesis directed by cowpea mosaic virus RNAs
No full textThe study described here concernes the proteins that are synthesized under direction of CPMV-RNAs.In chapter III it is described that sufficient radioactive labelling of proteins was achieved when 35 S as sulphate was administered to intact Vigna plants, cultivated in Hoagland solution. After fractionation of the cells, a fraction containing virus-specific (vesicle) structures could be isolated in which the majority of the replicase activity and CPMV-specific dsRNA was located. Comparison of proteins extracted from these fractions from infected and mock-infected leaves resulted in the detection of twoproteins, besides the coat proteins. These proteins, with molecular weights of about 170,000 and 72,000 could only be detected after the development of the radioactive labelling technique using 35 S as sulphate.In vitro studies using the messenger-dependent lysate from rabbit reticulocytes (MDL) and wheat germ extracts show that the virion RNAs stimulate the incorporation of amino acids in acid precipitable material. The optimization and characteristics of both in vitro systems are described in chapter IV.Product analysis of the synthesized polypeptides shows that the CPMV-RNAs can be reproducibly translated into well defined products (chapter V), indicating that these RNAs act well as messengers in the cell-free systems used. From the characteristics of these systems and the product analysis, it has become clear that CPMV-RNAs needed particular conditions for their in vitro translation (chapter IV and V). In wheat germ extracts the addition of spermidine (0.4 mM) together with a lowering of the Mg 2+ concentration to about 3.0 mM was required for the efficient translation of CPMV-RNAs. Furthermore, increasing the K + concentration to 130 mM was advantageous for the translation into high molecular weight polypeptides. In the MDL the addition of heterologous tRNA was absolutely necessary for the translation of CPMV-RNA into high molecular weight products.Estimations of the molecular weights by polyacrylamide gel electrophoresis in SDS containing gels, of the products synthesized, showed that there is a considerable variation in the molecular weights determined. The molecular weight of BP (the largest product synthesized under direction of B-RNA) was estimated to be 180,000 to 190,000. MP 1 (the large molecular weight product synthesized under direction of M RNA) has a molecular weight that varies from 110,000 to 125,000. The other largepolypeptide synthesized under direction of M-RNA (MP 2 ) has an estimated molecular weight between 105,000 and 95,000.Comparison between the polypeptides synthesized in both types of extract shows that the products are - at least electrophoretically - identical (chapter VI). Also in chapter VI it is described that comparison with virus-specific proteins found in vivo gives little information about either the origin of the virus-specific proteins found in vivo or about the nature of the in vitro synthesized polypeptides.In all the in vitro translation experiments no coat proteins could be detected among the translation products. In chapter VII experiments are described which were undertaken to reveal the translation strategy of CPMV-RNAs. From these experiments it was concluded that it was very unlikely that the coat proteins are synthesized from subgenomic messengers nor from internal initiation sites. The overall conclusion is that the large polypeptides synthesized under direction of Band M-RNA are probably precursor molecules from which the coat proteins (and other virus-specific proteins) are generated by a mechanism of posttranslational cleavage. Processing experiments in either wheat germ extracts or MDL did not, up until now, reveal any precursor- product relations hip between the polypeptides synthesized. This is in contrast to other findings where in MDL the M-RNA specific products could be processed (Pelham, Virology 96, 463), albeit into products not recognized as being virus-specific proteins.<p/
Effect of MP‐AzeFlu compared to monotherapy on COX‐2, PGE2, and EP2 gene expression in upper airway mucosa
No full textAbstract MP‐AzeFlu (intranasal fluticasone and azelastine) has been widely studied and has demonstrated efficacy in Allergic rhinitis with a superior effect compared to these drugs administered individually; however, the mechanism by which MP‐AzeFlu produces this improved clinical effect has not yet been fully explained. In this study, we investigated the effect of MP‐AzeFlu and fluticasone propionate (FP) on arachidonic acid metabolism as measured by changes in regulation of cyclooxygenase (COX) isoforms, prostaglandin (PG) D2, PGE2, PGE2 receptor (EP) 2, and EP3. Expression of these key inflammation markers was assessed through an in vitro model of upper airway inflammation using fibroblasts derived from both healthy and inflamed upper airway mucosa. Both MP‐AzeFlu and FP inhibited interleukin‐1β‐induced COX‐2 messenger RNA (mRNA) and protein expression and PGE2 secretion in vitro. MP‐AzeFlu and FP both upregulated EP2 mRNA expression, though neither upregulated EP2 protein expression. This downregulation of COX‐2 and PGE2 coupled with upregulation of EP2 receptor expression reinforces the anti‐inflammatory effect of MP‐AzeFlu in upper airway inflammation
