PIDR(s): IDR(s) as a Projection Method
No full textThe Induced Dimension Reduction(s) method (or the IDR(s) method) is an example of an iterative method used for solving systems of linear equations. Projection methods are a special type of iterative method. They find an approximate solution in a subspace (the right subspace) by requiring that the residual is orthogonal to another subspace (the left subspace). In this thesis we investigate how we can implement IDR(s) as a projection method. We call this method IDR(s), which stands for Projected IDR(s).We present an implementation of PIDR(s) for solving systems of linear equations and for solving eigenvalue problems. These implementations are not meant to be optimal, but they are used to show that IDR(s) can indeed be seen as a projection method.Track: educationScience Education and CommunicationApplied Science

Urokinase treatment for severe neurological complications in a patient with thrombotic thrombocytopenic purpura
No full textIn a patient with thrombotic thrombocytopenic purpura (TTP) severe neurological complications leading to coma were repeatedly reversed by treatment with urokinase. Although the therapeutic modalities for TTP still appear to be a matter of debate, thrombolytic treatment could be considered in TTP patients with severe organ involvement before the corresponding function is completely compromised
When self-consistency makes a difference
No full textCompound semiconductor power RF and microwave device modeling requires, in many cases, the use of selfconsistent electrothermal equivalent circuits. The slow thermal dynamics and the thermal nonlinearity should be accurately included in the model; otherwise, some response features subtly related to the detailed frequency behavior of the slow thermal dynamics would be inaccurately reproduced or completely distorted. In this contribution we show two examples, concerning current collapse in HBTs and modeling of IMPs in GaN HEMTs. Accurate thermal modeling is proved to be be made compatible with circuit-oriented CAD tools through a proper choice of system-level approximations; in the discussion we exploit a Wiener approach, but of course the strategy should be tailored to the specific problem under consideratio
Antiplatelet treatment in septic shock with severe bleeding and thrombocytopenia
No full textThe authors have seen a patient with septic shock candidosis of the biliary ducts, severe hemorrhagic syndrome and marked thrombocytopenia, who was successfully treated with antiplatelet drugs, associated with replacement therapy and an antifibrinolytic agent. The patient was a 42-yr-old woman who had undergone cholecystectomy two years previously and had since suffered repeated episodes of abdominal pain with hyperpyrexia and jaundice. During one of the episodes, the patient was admitted to the surgical department. A few hours later, shock and anuria occurred; the next day, despite massive fluid replacement, she was still in severe shock. At laparotomy, a stone occluding the choledochus was removed and Kehr drainage placed; neither hepato-splenomegaly nor other alterations of the abdominal organs was observed; profuse bleeding occurred during surgery. The patient was bleeding profusely from the surgical wound, the peritoneal drainage, the gastric cannula and the site of catheterization of the subclavian vein. Laboratory data obtained shortly thereafter showed severe thrombocytopenia but no gross laboratory abnormalities of the clotting and fibrinolytic systems. These data suggested there might be in vivo platelet consumption; treatment with dipyridamole, 25 mg every 6 hours, and lysine acetylsalicylate-L-ASA-, 450 mg every 12 hours i.v. was therefore associated with replacement therapy (red blood cells, fresh frozen plasma and platelet concentrates). Within 10 hours the shock subsided and diuresis started. On the second postoperative day, due to persistent severe thrombocytopenia and hemorrhagic syndrome, without signs of activated coagulation, treatment with E-aminocaproic acid-E-ACA-, 4 g every six hours i.v., was also instituted. From the third postoperative day, hemorrhage progressively decreased. Platelet transfusions were no longer administered after the fifth day, when the platelet count began to rise. Treatment with E-aminocaproic acid was stopped on the sixth day. Ten days after laparotomy, the patient was transferred to the wards; her general condition had markedly improved, no further bleeding had been reported and the platelet count had gradually reached the normal range. Oral antiaggregating treatment with dipyridamole alone, 420 mg per day, was prescribed.(Szirmai - Stuttgart

No full textMy research analyzes the characteristics of the first reception of husserlian phenomenology in the United States. The base of this work is a detailed historiographical reconstruction of this phase representing the point of departure of all those studies on phenomenological tradition that have been developed in the American academic world. Several institutions belong to the context in which this reception took place: the New School for Social Research as the original center for the teaching of phenomenology and a number of societies arisen since the sixties to diffuse Husserl’s philosophy in the United States (First Part: Chapter 2 and Chapter 3).
This first reception, promoted since the late thirties by Kaufmann, Schutz, Gurwitsch, Cairns and Farber, must be distinguished from an earlier phase, presenting only the general approach to Husserl’s thought of some American scholars (Second Part: Chapter 1). The origin of the studies of each author undoubtedly typifies their promotion of husserlian phenomenology: Gurwitsch, Schutz and Kaufmann belong to the European tradition, (First Part: Chapter 1) while the Americans Farber and Cairns mainly owe the growing interest in Husserl’s thought to their studies in Freiburg (Second Part: Chapter 2). Nevertheless, during this phase of reception of phenomenology, the original adherence to his lesson – useful to distinguish them from others Husserl’s students emigrated in United States – gradually disappears from their critiques. The aim of my research is to single out the salient features that characterize the different interpretations of Husserl’s thought elaborated by each author, whereas their originality can be indicated as decisive for following developments (Third Part). Gurwitsch builds an interesting critique of Husserl’s whole-part theory, focuses his analysis on the noema, and elaborates a non-egological conception of consciousness. Schutz’s critique of transcendental phenomenology mainly refers to his concept of mundane intersubjectivity. For what concerns Cairns, his few writings published until now don’t allow to deepen the exam on his interpretation. After the arrival in the United States, Kaufmann concentrates his discussion on the relationship between husserlian phenomenology and the logic. Farber proposes a critique which is far from being an original interpretation, although his analysis remains bound to the interest in phenomenology until the end.
With this work I want to explain how the interest about husserlian phenomenology began in the United States, who were its promoters, and also what kind of interpretations they developed in the American academic world. It must be considered that they hadn’t a decisive influence on further developments of phenomenological studies, but in any case helped bringing the attention on Husserl’s thought throughout their teaching
