No full textA Guiné-Equatorial, um dos países pouco conhecidos do continente africano, é analisado por Max Liniger-Goumaz do ponto de vista das origens e da herança colonial. A máquina do Estado, os responsáveis políticos, os interesses locais e, principalmente, os interesses externos, são analisados segundo conexões com o esquema da autoridade local. O autor mostra ainda que as alterações ocorridas em termos do sistema de poder não correspondem a mudanças reais no plano político econômico.nuloEquatorial Guinea, one of the countries less known on the African Continent, is analyzed by Max Liniger-Goumaz the points of view on origins and heritance the colonial. The state machine, the responsible politicians, local interests and mainly foreign interests, are analyzed according to their connections with the scheme of local authority. The author still shows that chances done in the ruling system do not correspond to the real changes in the political economic plan
Drude Weight for the Lieb-Liniger Bose Gas
No full textBased on the method of hydrodynamic projections we derive a concise formula
for the Drude weight of the repulsive Lieb-Liniger -Bose gas. Our
formula contains only quantities which are obtainable from the thermodynamic
Bethe ansatz. The Drude weight is an infinite-dimensional matrix, or bilinear
functional: it is bilinear in the currents, and each current may refer to a
general linear combination of the conserved charges of the model. As a
by-product we obtain the dynamical two-point correlation functions involving
charge and current densities at small wavelengths and long times, and in
addition the scaled covariance matrix of charge transfer. We expect that our
formulas extend to other integrable quantum models

Vakuum-Reposition einer Pingpong-Fraktur beim Neugeborenen
No full textSchädelimpressionen beim Neugeborenen können pränatal oder perinatal, dann meist im Rahmen einer instrumentell-assistierten Geburt, entstehen und sind insgesamt selten. Traditionell werden solche Frakturen operativ versorgt. Wir machen mit diesem Fall auf eine einfache und sichere Methode der geschlossenen Reposition aufmerksam
Interaction and external field quantum quenches in the Lieb-Liniger and Gaudin-Yang model
No full textA review of the solution of the Lieb-Liniger is given. Using the wave function, the dynamics after a quench with a time dependent interaction strength is studied. Directly calculating the overlaps of wave functions, an interaction strength linear in time is examined. Furthermore utilizing those overlaps and the so called Yudson representation a time periodic interaction strength is studied. Moreover the dynamics of the Lieb-Liniger model with an external homogenous field is analyzed. After giving a review of the solution of the Gaudin-Yang model, an outlook on how the wave function for the Gaudin-Yang model in an external homogenous field could be obtained is given.M.S.Includes bibliographical referencesby Stefan M.

Computational Evidence for Laboratory Diagnostic Pathways: Extracting Predictive Analytes for Myocardial Ischemia from Routine Hospital Data
No full textBackground: Laboratory parameters are critical parts of many diagnostic pathways, mortality scores, patient follow-ups, and overall patient care, and should therefore have underlying standardized, evidence-based recommendations. Currently, laboratory parameters and their significance are treated differently depending on expert opinions, clinical environment, and varying hospital guidelines. In our study, we aimed to demonstrate the capability of a set of algorithms to identify predictive analytes for a specific diagnosis. As an illustration of our proposed methodology, we examined the analytes associated with myocardial ischemia; it was a well-researched diagnosis and provides a substrate for comparison. We intend to present a toolset that will boost the evolution of evidence-based laboratory diagnostics and, therefore, improve patient care. Methods: The data we used consisted of preexisting, anonymized recordings from the emergency ward involving all patient cases with a measured value for troponin T. We used multiple imputation technique, orthogonal data augmentation, and Bayesian Model Averaging to create predictive models for myocardial ischemia. Each model incorporated different analytes as cofactors. In examining these models further, we could then conclude the predictive importance of each analyte in question. Results: The used algorithms extracted troponin T as a highly predictive analyte for myocardial ischemia. As this is a known relationship, we saw the predictive importance of troponin T as a proof of concept, suggesting a functioning method. Additionally, we could demonstrate the algorithm’s capabilities to extract known risk factors of myocardial ischemia from the data. Conclusion: In this pilot study, we chose an assembly of algorithms to analyze the value of analytes in predicting myocardial ischemia. By providing reliable correlations between the analytes and the diagnosis of myocardial ischemia, we demonstrated the possibilities to create unbiased computational-based guidelines for laboratory diagnostics by using computational power in today’s era of digitalization
Local resection of metanephric adenoma with kidney preservation
No full textMetanephric adenoma (MA) is a rare renal neoplasm present at any age. Usually, a total nephrectomy is performed. Some successful partial nephrectomies or selective tumor resections are described in adults but not in children. We present here the case of a 15-month-old boy, the youngest patient yet to be reported with an MA. We performed a local resection of the tumor. Today, 2 1/2 years after surgery, we can document a favorable clinical course and normal ultrasound findings in the follow-up of the operated kidney. This case gives further evidence that organ-sparing resection of MA is feasible in selected cases. A close clinical and ultrasound follow-up is mandatory for this approach
