Machine Learning and Field Inversion approaches to Data-Driven Turbulence Modeling
… improved closure for the Reynolds stress tensor field. The first approach uses machine learning to learn a general closure model from data. A novel framework is developed to train deep neural networks using experimental velocity and pressure measurements. The sensitivity of the RANS equations to …

Optimization for source localization and geoacoustic inversion in underwater acoustics
Matched-field inversion techniques are widely used for source localization and geoacoustic parameter estimation. These inversion methods correlate the received data with modeled data and find the model parameters which provide the maximum correlation. However, when a large number of unknown …

Monte Carlo Simulation Of Hole Transport And Terahertz Amplification In Multilayer Delta Doped Semiconductor Structures
… presence of a perpendicular in-plane magnetic field. Inversion population on intersubband transitions arises due to light hole accumulation in E B fields, as in the bulk p-Ge laser. However, the considered structure achieves spatial separation of hole accumulation regions from the doped layers, …

Higher order chromatin degradation induced by hydrogen peroxide in glial cells
… embedding and its fragmentation was assessed by field inversion gel electrophoresis (FIGE). To detect single strand fragmentations, the DNA was digested with S1 nuclease before FIGE. We found that the exposure of oligodendrocytes to pathological concentrations of H2O2, induces a rapid digestion …

Physics-Informed, Data-Driven Framework for Model-Form Uncertainty Estimation and Reduction in RANS Simulations
… data and empirical prior knowledge for a full-field inversion. The merits of incorporating prior knowledge and physical constraints in calibrating RANS model discrepancies are demonstrated and discussed. Second, a random matrix theoretic framework is proposed for estimating model-form …

Cartographie de grands fragments d'ADN des chaines Kappa d'immunoglobulines de souris BALB/c
… A l'aide de la technique d'électrophorèse par Inversion de champ (FIGE pour "Field Inversion Gel Electrophoresis") nous avons établi quatre cartes de restriction de grands fragments d'ADN associées à la région constante Ck de la chaîne légère des Immunoglobulines de souris BALB/c. Au total, …

A quasi-dynamic and self-consistent rupture model to simulate earthquake ruptures
… defined by a previously performed moment tensor inversion. The simultanously inverted scalar seismic moment allows an estimation of the extension of the rupture. The modeled rupture plane is discretized by a set of rectangular boundary elements. For each boundary element an applied traction …

Physical mapping of a 2-Mb region centered at D10S94, a locus very tightly linked to the multiple endocrine neoplasia type 2 gene(s)
… genes. Long range restriction mapping by pulsed field gel electrophoresis revealed a dense cluster of CpG islands at D10S94. Genes potentially associated with these CpG islands represent candidate genes for MEN2. To determine whether relatively large sequence alterations, which could serve to …
