Suzanne Clauser
No full textAus einer österreichisch-französischen Familie stammend, ist Suzanne Clauser (ps. Dominique Auclères, *16. 5. 1898 in Wien, † 11.9.1981 in Paris) in Frankreich unter dem Pseudonym Dominique Auclères als Übersetzerin und Journalistin bekannt geworden. Ihre literarische Vermittlertätigkeit ist eng mit dem Werk von Arthur Schnitzler verbunden, dessen Rezeption in Frankreich sie ab Ende der 1920-er Jahre entscheidend prägt. Ausser ihrer Rolle für die französische Schnitzler-Rezeption ist Dominique Auclères vor allem als « grand reporter » der Tageszeitungen Le Journal und Le Figaro hervorgetreten, in denen sie sich als Spezialistin für Mitteleuropa und den Balkan etabliert hat. Ihre Erfahrungen als « grand reporter » und (aussen-)politische Journalistin hat sie in Mes quatre vérités, Vent du large, 1948, und in Mes fenêtres sur l’Histoire, Plon, 1978, verarbeitet. Ausserdem hat sie veröffentlicht: Anastasia, qui êtes-vous ?, Hachette, 1962, eine « Docu-fiction » über Anastasia, eine Tochter von Zar Nikolaus II, sowie zwei Bücher zur Habsburger-Dynastie : Les Enfants de Toscane, Presses de la Cité, 1969 (gemeint sind die Kinder des Großherzogs von Toskana, Ferdinand IV Salvator, 1835–1908), und Soleil d’exil : le bannissement des Habsbourg, Presses de la Cité, 1974
New mini-osteotomy of the infraorbital nerve in bony decompression for endocrine orbitopathy
No full textEndocrine orbitopathy is a systemic complex disease that involves the orbital contents. The symptoms are exophthalmos and correlated. The surgical techniques used to correct this condition can be fat decompression by the Olivari technique, 3-wall bony decompression, or the combination of these 2 surgical strategies, the ancillary procedure. Fat decompression is indicated when the intraconal and extraconal fat tissue is increased, whereas bony decompression is used in the presence of extraocular muscle involvement, associated with a normal quantity of intraconal-extraconal fat. Surgical techniques include the transconjunctival approach and ostectomy of the medial wall (when possible through endoscopy), orbital floor, and lateral wall of the orbit.Complications of this type of intervention are often represented by sensitivity disorders of the second branch of the trigeminal nerve, compressed by the intraorbital contents when they prolapse into the sinus. Possible sensitivity disorders are paresthesia, anesthesia, hypoaesthesia, dysesthesia, and hyperesthesia.The innovation introduced by the first author in 2007 consists of a mini ostectomy around the infraorbital foramen with removal of bone fragment. This determines relaxation of the nerve and makes easier the descent toward the sinus, allowing a larger expansion of the orbit contents. The absence of compression significantly reduces the sensitive complications. After treatment of the basic disease, surgical indications should be given according to the Werner classification. Fat decompression with the coronal approach is almost entirely abandoned for the transconjunctival approach, which allows adequate exposure of the lower orbit.The use of mini ostectomy of the infraorbital foramen combined with a 3-wall bony expansion showed a significant reduction of sensitive complications that often cause patient discomfort
On The Complete Description Of Entangled Systems Part I: Hidden Variables And The Context Communication Cost of Simulating Quantum Correlations

correlations are capable of violating Boole's conditions of possible
experience, such as the Clauser-Horne-Shimony-Holt inequality, even beyond the
Tsirelson bound. This can be achieved by communicating a single bit encoding

Laying the foundation for building a Quantum Networking Benchmark suite using Quantum Network Applications: Evaluating the inclusion of the Clauser-Horne-Shimony-Holt game quantum network application
No full textThe rapid advancement of Quantum Network architectures necessitates a comprehensive and quantitative comparison to assess their effectiveness and performance. Unfortunately, there does not exist an implemented quantum network benchmark suite capable of determining the superior architecture. Hence, our study aims to establish the foundation for developing a benchmark suite by leveraging existing quantum network applications. However, the specific inclusion of quantum network applications in the suite remains to be determined. Therefore, to address this gap, our study will explore the potential inclusion of the Clauser-Horne-Shimony-Holt (CHSH) game based on its effectiveness in identifying errors within various properties of the quantum networking system. We use an exploratory research methodology involving experiments performed on simulated quantum networks utilizing SquidASM. Each experiment simulates multiple quantum networks, with a single property as the independent variable. For each value of the independent variable, we calculate both the success probability of the game and the number of successes per second. Subsequently, we employ the one-way ANOVA test to examine if there are significant variations in these performance metrics. Our results demonstrate that the CHSH game exhibits sensitivity to all properties affecting the quality of entanglement between nodes, execution time, and the error probability of both single-qubit gates and measure operations. Additionally, we compare the success probabilities based on different input combinations using the Root Mean Squared metric to uncover any underlying patterns within the data. As a result, we discovered a procedure for quantifying the difference between the error probabilities of measurements of zero and one. Based on the outcomes of our study, we consider the CHSH game to be a suitable addition to the benchmark suite if the testing requirements of the suite align with the qualities offered by the application. We anticipate that these results will aid the development of the benchmark suite and advance the understanding of quantum network architectures and their evaluationhttps://gitlab.com/tmaliappis28/research-project Repository link Public repository containing all code used in the project ShowEdit https://surfdrive.surf.nl/files/index.php/s/w7qq3pQXYgUkr8T?path=%2FResults%2FCHSH%20game%20-%20Thomas%20Maliappis Surfdrive that contains also all code used in the projectCSE3000 Research ProjectComputer Science and Engineerin
The Matrisome: In Silico Definition and In Vivo Characterization by Proteomics of Normal and Tumor Extracellular Matrices
No full textThe extracellular matrix (ECM) is a complex meshwork of cross-linked proteins providing both biophysical and biochemical cues that are important regulators of cell proliferation, survival, differentiation, and migration. We present here a proteomic strategy developed to characterize the in vivo ECM composition of normal tissues and tumors using enrichment of protein extracts for ECM components and subsequent analysis by mass spectrometry. In parallel, we have developed a bioinformatic approach to predict the in silico “matrisome” defined as the ensemble of ECM proteins and associated factors. We report the characterization of the extracellular matrices of murine lung and colon, each comprising more than 100 ECM proteins and each presenting a characteristic signature. Moreover, using human tumor xenografts in mice, we show that both tumor cells and stromal cells contribute to the production of the tumor matrix and that tumors of differing metastatic potential differ in both the tumor- and the stroma-derived ECM components. The strategy we describe and illustrate here can be broadly applied and, to facilitate application of these methods by others, we provide resources including laboratory protocols, inventories of ECM domains and proteins, and instructions for bioinformatically deriving the human and mouse matrisome.National Cancer Institute (U.S.) (U54 CA126515
On the complete description of entangled systems part I–exploring hidden variables and context communication cost in simulating quantum correlations
No full textIn this article, we investigate classical simulations of quantum-type probabilities and correlations that defy Boole’s conditions of possible experience, specifically the Clauser-Horne-Shimony-Holt inequality, and even surpass the Tsirelson bound. We demonstrate that such violations can be achieved by encoding a single bit to communicate the measurement context. Our findings highlight the crucial role of context communication in reproducing quantum correlations that are stronger than classical limits, providing insights into the fundamental principles underlying entangled systems
Quantifying Uncertainty in Fractured Geothermal Reservoirs Using a Discrete Fracture Model
No full textFractures occur at varying scales and orientations in the subsurface. The role of fractures as conduits for fluid flow in a reservoir must be well constrained for planning and development of a geothermal system. This study examines the uncertainty associated with fractures in a rock matrix using a discrete fracture network modelling approach; fractures are considered as discrete elements embedded in a rock matrix. Many fractures are below the resolution of geophysical investigation methods and are therefore typically described by a statistical distribution of permeability, length and orientation. A Monte Carlo approach is used whereby multiple reservoir simulations are conducted using fracture network parameters drawn randomly from a pre-defined distribution. The simulation results show that fracture permeability is the major factor which influences the production. An increase in fracture network permeability from 8:33x10-^12 m2 to 8:33x10-^10 m2 showed an increase of uncertainty in reservoir production by up to a factor of six when considering the standard deviation. The results show that this uncertainty increases by up to 200 % with the life of the reservoir for the high permeability case. Stochastic analysis of the azimuth uncertainty revealed an opposite trend where a decrease in uncertainty of 34 % was observed over the 30 year simulated lifetime of the reservoir. The orientation of fractures in the reservoir was found to play an important role in the temperature field in the reservoir with increases in production temperature ranging from 0:5 K to 3 K resulting from the proximity of fractures to the production well. The results also indicate that discrete fracture networks which possess similar orientations of fractures produce statistically similar production profiles. The findings of this study show that a stochastic approach can be used for efficient planning of geothermal doublet systems based on expected trends in production.Civil Engineering and GeosciencesGeoscience & EngineeringJoint Master's in Applied Geophysics: Delft University of Technology, ETH Zürich, RWTH Aachen Universit
Unveiling contextual realities by microscopically entangling a neutron
No full textThe development of qualitatively new measurement capabilities is often a prerequisite for critical scientific and technological advances. Here we introduce an unconventional quantum probe, an entangled neutron beam, where individual neutrons can be entangled in spin, trajectory and energy. The spatial separation of trajectories from nanometers to microns and energy differences from peV to neV will enable investigations of microscopic magnetic correlations in systems with strongly entangled phases, such as those believed to emerge in unconventional superconductors. We develop an interferometer to prove entanglement of these distinguishable properties of the neutron beam by observing clear violations of both Clauser-Horne-Shimony-Holt and Mermin contextuality inequalities in the same experimental setup. Our work opens a pathway to a future of entangled neutron scattering in matter.RID/TS/Instrumenten groepRID/Algemeen/Bedrijfsondersteunin
