MATHICSE Technical Report : A multi level Monte Carlo method with control variate for elliptic PDEs with log-normal coefficients
Creators: name: Nobile, Fabio
name: Tesei, Francesco
Publisher: name: Écublens, MATHICSE
Year: 2019

description: We consider the numerical approximation of the stochastic Darcy problem with log-normal permeability field and propose a novel Multi Level Monte Carlo approach with a control variate variance reduction technique on each level. We model the log-permeability as a stationary Gaussian random field with a covariance function belonging to the so called Matérn family, which includes both fields with very limited and very high spatial regularity. The control variate is obtained starting from the solution of an auxiliary problem with smoothed permeability coefficient and its expected value is effectively computed with a Stochastic Collocation method on the finest level in which the control variate is applied. We analyze the variance reduction induced by the control variate, and the total mean square error of the new estimator. To conclude we present some numerical examples and a comparison with the standard Multi Level Monte Carlo method, which shows the effectiveness of the proposed method.

description: Bromodomain-containing protein 4 (BRD4) is a member of the bromodomain and extra-terminal domain (BET) family of proteins. It epigentically regulates the transcription of growth-promoting genes and has become an attractive target for the development of anticancer and anti-inflammatory agents. In the current study, we performed an in silico screening of a small-molecule chemical library against the acetyl–lysine binding site of the first bromodomain (BD1) in BRD4 protein. Potential inhibitors identified through virtual screening were further studied through molecular dynamics simulations, water entrapment analysis and Molecular Mechanics (MM)/Poisson–Boltzmann surface area (PBSA) binding free energy calculations. Many of the identified compounds exhibit better G-score (–11.64 kcal∙mol−1 to –10.31 kcal∙mol−1) and predicted binding affinity (–9.66 kcal∙mol−1 to –6.63 kcal∙mol−1) values towards BRD4-BD1 than that of the reference compound (+)-JQ1. Molecular dynamics simulation studies show that in free-form BRD4 the reported conserved water molecules are not retained at their specific positoins due to flexibiliy in the ZA-loop. In BRD4–ligand complexes the number and positions of conserved water molecules depends on the bound ligand. Identified potential inhibitors bind stably at the acetyl–lysine binding pocket of BRD4 and form direct and water-mediated hydrogen bonds with higher occupancy which may contribute to ligand specificity towards BRD4-BD1. Further, through MM/PBSA we calculated the binding free energies of selected compounds, which shows that they have comparable energies to that of (+)-JQ1, while NSC744713 shows better binding free energy.

description: Mirroring the increasing percentage of women in the professional workforce, the number of females in sales has dramatically risen in recent years. The growth of gender diversity within the world of B-to-B buying and selling requires an examination of potential gender effects associated with interpersonal communications. The latter influences perceptions of authenticity, which in turn, influence sales effectiveness. The current study uses an international sample to review interpersonal communication drivers that are associated with buyer perceptions of salesperson authenticity. Gender differences associated with the processing of body language and the spoken word are particularly examined. Results indicate that, in high-involvement sales situations, female perceptions of salesperson authenticity are highly influenced by salesperson body language. Male perceptions, conversely, are more heavily influenced by the spoken word. Implications for sales training are provided.

description: We study the helicity distributions of light flavor quark-antiquark ($q \bar{q}$) pairs in the nucleon sea. The valence quarks are handled by adopting the light-cone SU(6) quark-spectator-diquark model and the sea $q \bar{q}$ pairs are treated from statistical consideration by introducing the helicity suppression factors $l_q(x)$ and $\bar l_q(x)$ to parametrize the helicity distributions of q-flavor sea quark and antiquark respectively, while $Δl_q(x)=l_q(x)-\bar l_q(x)$ represents a combined effect of helicity contribution due to sea $q \bar{q}$ pairs. From fitting the nucleon polarization asymmetries $A^N_1$ in inclusive deep inelastic scattering processes and the single-spin asymmetries $A^{W^{\pm}}_L$ in Drell-Yan type processes, we find a significant asymmetry between the quark and antiquark helicity distributions of the nucleon sea. Therefore the quark-antiquark asymmetry of helicity distributions of nucleon sea $q \bar{q}$ pairs, i.e., $Δq_s(x) \neq Δ\bar q_s(x)$, plays an important role for a comprehensive understanding of the nucleon spin content.

Year: 2019

description: We study the accuracy of the discrete least-squares approximation on a finite dimensional space of a real-valued target function from noisy pointwise evaluations at independent random points distributed according to a given sampling probability measure. The convergence estimates are given in mean-square sense with respect to the sampling measure. The noise may be correlated with the location of the evaluation and may have nonzero mean (offset). We consider both cases of bounded or square-integrable noise / offset. We prove conditions between the number of sampling points and the dimension of the underlying approximation space that ensure a stable and accurate approximation. Particular focus is on deriving estimates in probability within a given confidence level. We analyze how the best approximation error and the noise terms affect the convergence rate and the overall confidence level achieved by the convergence estimate. The proofs of our convergence estimates in probability use arguments from the theory of large deviations to bound the noise term. Finally we address the particular case of multivariate polynomial approximation spaces with any density in the beta family, including uniform and Chebyshev.

Publisher: name: Écublens, MATHICSE

description: In this work we build on the classical adaptive sparse grid algorithm (T. Gerstner and M. Griebel, Dimension-adaptive tensor-product quadrature), obtaining an enhanced version capable of using non-nested collocation points, and supporting quadrature and interpolation on unbounded sets. We also consider several profit indicators that are suitable to drive the adaptation process.We then use such algorithm to solve an important test case in Uncertainty Quantification problem, namely the Darcy equation with lognormal permeability random field, and compare the results with those obtained with the quasi-optimal sparse grids based on profit estimates, which we have proposed in our previous works (cf. e.g. Convergence of quasi-optimal sparse grids approximation of Hilbert-valued functions: application to random elliptic PDEs). To treat the case of rough permeability fields, in which a sparse grid approach may not be suitable, we propose to use the adaptive sparse grid quadrature as a control variate in a Monte Carlo simulation. Numerical results show that the adaptive sparse grids have performances similar to those of the quasi-optimal sparse grids and are very effective in the case of smooth permeability fields. Moreover, their use as control variate in a Monte Carlo simulation allows to tackle efficiently also problems with rough coefficients, significantly improving the performances of a standard Monte Carlo scheme.

description: In this work we introduce the Multi-Index Stochastic Collocation method (MISC) for computing statistics of the solution of a PDE with random data. MISC is a combination technique based on mixed differences of spatial approximations and quadratures over the space of random data. We propose an optimization procedure to select the most eective mixed differences to include in the MISC estimator: such optimization is a crucial step and allows us to build a method that, provided with sufficient solution regularity, is potentially more eective than other multi-level collocation methods already available in literature. We then provide a complexity analysis that assumes decay rates of product type for such mixed differences, showing that in the optimal case the convergence rate of MISC is only dictated by the convergence of the deterministic solver applied to a one dimensional problem. We show the effectiveness of MISC with some computational tests, comparing it with other related methods available in the literature, such as the Multi- Index and Multilevel Monte Carlo, Multilevel Stochastic Collocation, Quasi Optimal Stochastic Collocation and Sparse Composite Collocation methods.

description: We present a theoretical analysis of the CORSING (COmpRessed SolvING) method for the numerical approximation of partial differential equations based on compressed sensing. In particular, we show that the best s-term approximation of the weak solution of a PDE with respect to an orthonormal system of N trial functions, can be recovered via a Petrov-Galerkin approach using m << N orthonormal test functions. This recovery is guaranteed if the local a-coherence associated with the bilinear form and the selected trial and test bases fulfills suitable decay properties. The fundamental tool of this analysis is the restricted infsup property, i.e., a combination of the classical inf-sup condition and the well-known restricted isometry property of compressed sensing.

MATHICSE Technical Report : Discrete least-squares approximations over optimized downward closed polynomial spaces in arbitrary dimension
Creators: name: Cohen, Albert
name: Migliorati, Giovanni
name: Nobile, Fabio
Publisher: name: Écublens, MATHICSE
Year: 2019

description: We analyze the accuracy of the discrete least-squares approximation of a function u in multivariate polynomial spaces $P_\Lambda := span\{y \mapsto y^\nu | \nu \in \Lambda\}$ with $\Lambda\subset N_0^d$ over the domain $\Gamma := [-1,1]^d$, based on the sampling of this function at points $y^1,...,y^m \in \Gamma$. The samples are independently drawn according to a given probability density $\rho$ belonging to the class of multivariate beta densities, which includes the uniform and Chebyshev densities as particular cases. Motivated by recent results on high-dimensional parametric and stochastic PDEs, we restrict our attention to polynomial spaces associated with downward closed sets $\Lambda$ of prescribed cardinality n and we optimize the choice of the space for the given sample. This implies in particular that the selected polynomial space depends on the sample. We are interested in comparing the error of this least-squares approximation measured in $L^2(\Gamma,\rho)$ with the best achievable polynomial approximation error when using downward closed sets of cardinality n. We establish conditions between the dimension n and the size m of the sample, under which these two errors are proven to be comparable. Our main finding is that the dimension d enters only moderately in the resulting trade-off between m and n, in terms of a logarithmic factor ln(d), and is even absent when the optimization is restricted to a relevant subclass of downward closed sets, named anchored sets. In principle, this allows one to use these methods in arbitrarily high or even infinite dimension. Our analysis builds upon [3] which considered fixed and non-optimized downward closed multi-index sets. Potential applications of the proposed results are found in the development and analysis of efficient numerical methods for computing the solution of high-dimensional parametric or stochastic PDEs, but is not limited to this area.

description: We analyze the recent Multi-index Stochastic Collocation (MISC) method for computing statistics of the solution of a partial differential equation with random data, where the random coefficient is parametrized by means of a countable sequence of terms in a suitable expansion. MISC is a combination technique based on mixed differences of spatial approximations and quadratures over the space of random data and, naturally, the error analysis uses the joint regularity of the solution both with respect to the physical variables (the variables in the phys- ical domain) and the parametric variables (the parameters corresponding to randomness). In MISC, the number of problem solutions performed at each discretization level is not deter- mined by balancing the spatial and stochastic components of the error, but rather by suitably extending the knapsack-problem approach that we have employed in the construction of the quasi-optimal sparse-grids and Multi-index Monte Carlo methods. In this methodology, we use a greedy optimization procedure to select the most effective mixed differences to include in the MISC estimator and provide a complexity analysis based on a summability argument showing algebraic rates of convergence with respect to the overall computational work. We apply our theoretical estimates to a linear elliptic partial differential equation in which the diffusion coefficient is modeled as a random field whose realizations have spatial regularity determined by a scalar parameter (in the spirit of a Matérn covariance) and we estimate the rate of convergence in terms of the smoothness parameter, the physical dimension and the complexity of the linear solver. Numerical experiments show the effectiveness of MISC in this infinite-dimensional setting compared with Multi-index Monte Carlo, as well as the sharpness of the convergence result.

description: We review the spectral cover formalism for constructing both U(n) and SU(n) holomorphic vector bundles on elliptically fibered Calabi-Yau three-folds which admit a section. We discuss the allowed bases of these three-folds and show that physical constraints eliminate Enriques surfaces from consideration. Relevant properties of the remaining del Pezzo and Hirzebruch surfaces are presented. Restricting the structure group to SU(n), we derive, in detail, a set of rules for the construction of three-family particle physics theories with phenomenologically relevant gauge groups. We show that anomaly cancellation generically requires the existence of non-perturbative vacua containing five-branes. We illustrate these ideas by constructing four explicit three-family non-perturbative vacua.

Virus-host interaction sites as well as sites under positive selection in primate, rodent and bat NTCP sequences are given and compared between the three mammalian orders and other mammalian species in which NTCP-HBV interactions have been functionally tested. The variability at the preS1 domain, notably the essential and accessory domains that are crucial for HBV- NTCP interaction are presented for primate, rodent, and bat orthohepadnaviruses. The mammalian species that naturally host orthohepadnaviruses are indicated, as well as those with exogenous orthohepadnaviruses (that originated from isolated cross-species transmissions). On the far right, the known replication capacity of orthohepadnaviruses are indicated for the species that have been experimentally tested by others [21, 24, 47, 86], the corresponding references are indicated in bracket. The amino acids of rodent preS1 domains are not included, because they are too divergent to primate and bat orthohepadnavirus pres1 sequences making alignment uncertain.

description: The continuous monitoring of a quantum system strongly influences the emergence of chaotic dynamics near the transition from the quantum regime to the classical regime. Here we present a feedback control scheme that uses adaptive measurement techniques to control the degree of chaos in the driven-damped quantum Duffing oscillator. This control relies purely on the measurement backaction on the system, making it a uniquely quantum control, and is only possible due to the sensitivity of chaos to measurement. We quantify the effectiveness of our control by numerically computing the quantum Lyapunov exponent over a wide range of parameters. We demonstrate that adaptive measurement techniques can control the onset of chaos in the system, pushing the quantum-classical boundary further into the quantum regime.

description: We consider finite element error approximations of the steady incompressible Navier-Stokes equations defined on a randomly perturbed domain, the perturbation being small. Introducing a random mapping, these equations are transformed into PDEs on a fixed reference domain with random coefficients. Under suitable assumptions on the random mapping and the input data, in particular the so-called small data assumption, we prove the well-posedness of the problem. We assume then that the mapping depends affinely on $L$ independent random variables and adopt a perturbation approach expanding the solution with respect to a small parameter $\varepsilon$ that controls the amount of randomness in the problem. We perform an a posteriori error analysis for the first order approximation error, namely the error between the exact (random) solution and the finite element approximation of the first term in the expansion with respect to ". Numerical results are given to illustrate the theoretical results and the effectiveness of the error indicator.

description: The present work concerns the approximation of the solution map S associated to the parametric Helmholtz boundary value problem, i.e., the map which associates to each (real) wavenumber belonging to a given interval of interest the corresponding solution of the Helmholtz equation. We introduce a least squares rational Padé-type approximation technique applicable to any meromorphic Hilbert space-valued univariate map, and we prove the uniform convergence of the Padé approximation error on any compact subset of the interval of interest that excludes any pole. This general result is then applied to the Helmholtz solution map S, which is proven to be meromorphic in C, with a pole of order one in every (single or multiple) eigenvalue of the Laplace operator with the considered boundary conditions. Numerical tests are provided that confirm the theoretical upper bound on the Padé approximation error for the Helmholtz solution map.

description: We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials. Thermodynamic extensive variables on the macro-scale are obtained by integrating over a representative elementary volume (REV). Using Euler homogeneity of the first order, we obtain the Gibbs equation for the REV. From this we define the intensive variables, the temperature, pressure and chemical potentials and, using the balance equations, derive the entropy production for the REV. The entropy production defines sets of independent conjugate thermodynamic fluxes and forces in the standard way. The transport of two-phase flow of immiscible components is used to illustrate the equations.

The non-trivial background metric and RR five-form field strength play a crucial role in the solution. When a D5-brane is dragged across a stack of N D3-branes a bundle of N fundamental strings joining the two types of branes is created, as in the Hanany-Witten effect. Our solutions give a detailed description of this bundle in terms of a D5-brane wrapped on a sphere. We discuss extensions of these solutions which have an interpretation in terms of gauge theory multi-quark states via the AdS/CFT correspondence.

description: Supersymmetry breaking may be linked to the formation of gaugino condensates in a hidden sector. In this work, the process of formation of the condensate is examined in a cosmological context, using an effective field theory of the gaugino bilinear which provides a reasonable interpolation between the high- and low-temperature phases. The implementation of anomaly requirements generates a large potential barrier between the zero-condensate configuration and that of the true (SUSY-breaking) vacuum. As a consequence, the transition to bubbles of true vacuum may be subject to an enormous exponential suppression. This leads to the same difficulties with inhomogeneity of the universe which occurred in the original inflationary scenarios.

description: Many motivated extensions of the Standard Model predict the existence of cosmic strings. Gravitational waves originating from the dynamics of the resulting cosmic string network have the ability to probe many otherwise inaccessible properties of the early universe. In this study we show how the spectrum of gravitational waves from a cosmic string network can be used to test the equation of state of the early universe prior to Big Bang Nucleosynthesis (BBN). We also demonstrate that current and planned gravitational wave detectors such as LIGO, LISA, DECIGO/BBO, and ET/CE have the potential to detect signals of a non-standard pre-BBN equation of state and evolution of the early universe (e.g., early non-standard matter domination or kination domination) or new degrees of freedom active in the early universe beyond the sensitivity of terrestrial collider experiments and cosmic microwave background measurements.

description: The LASCAR campaign is a field experiment originally conducted to provide data for building and testing lidar based minute-scale forecasting models. The measurement goal was to capture the dominant westerly inflow to the Risø test site.
This was achieved by deploying 3 scanning lidars in a compact area surrounding building 313 at Risø. One unit (Sirocco) was stationed on the roof of the building and performed fast (13 s/scan) repeating PPI scans facing west with an elevation angle of zero degrees. This provides 2D horizontal slices of the wind inflow. Another scanning lidar (Whittle) was deployed on the ground in front (west) of the building, and performed repeating RHI scans (26 s/scan) to provide 2D vertical slices of the wind inflow. The third scanning lidar (Brise) was deployed on the ground behind (east) of the building and performed repeating 5-beam DBS scans to provide vertical profiles of the horizontal winds. Measurements from a nearby (V52 calibration) met-mast are also included in the dataset.
A complete written description of the experiment will be available in a forthcoming PhD thesis by Elliot Simon.
This is an original dataset. The lidar portion represents a level 2.3 data product in the FAIR lidar data schematics, that is geo-located radial velocities stored in NetCDF files with dimensions of time, range and line-of-sight number.The met-mast data format is a labelled HDF5 file.

description: We generalize several well known quantum equations to a Tsallis' q-scenario, and provide a quantum version of some classical fields associated to them in recent literature. We refer to the q-Schrödinger, q-Klein-Gordon, q-Dirac, and q-Proca equations advanced in, respectively, [Phys. Rev. Lett. {\bf 106}, 140601 (2011), EPL {\bf 118}, 61004 (2017) and references therein]. Also, we introduce here equations corresponding to q-Yang-Mills fields, both in the Abelian and not-Abelian instances. We show how to define the q-Quantum Field Theories corresponding to the above equations, introduce the pertinent actions, and obtain motion equations via the minimum action principle. These q-fields are meaningful at very high energies (TeVs) for $q=1.15$, high ones (GeVs) for $q=1.001$, and low energies (MeVs)for $q=1.000001$ [Nucl. Phys. A {\bf 955} (2016) 16 and references therein]. (See the Alice experiment of LHC). Surprisingly enough, these q-fields are simultaneously q-exponential functions of the usual linear fields' logarithms.

description: The relation between some perturbative non-BPS states of the heterotic theory on T^4 and non-perturbative non-BPS states of the orbifold limit of type IIA on K3 is exhibited. The relevant states include a non-BPS D-string, and a non-BPS bound state of BPS D-particles (`D-molecule'). The domains of stability of these states in the two theories are determined and compared.

MATHICSE Technical Report : A continuation multi level Monte Carlo (C-MLMC) method for uncertainty quantification in compressible aerodynamics

description: In this work we apply the Continuation Multi-Level Monte Carlo (C-MLMC) algorithm proposed by [Collier et al, BIT 2014] to efficiently propagate operational and geometrical uncertainties in compressible aerodynamics numerical simulations. The key idea of MLMC is that one can draw MC samples simultaneously and independently on several approximations of the problem under investigations on a hierarchy of nested computational grids (levels). The expectation of an output quantity is computed as a sample average using the coarsest solutions and corrected by averages of the differences of the solutions of two consecutive grids in the hierarchy. By this way, most of the computational effort is transported from the finest level (as in a standard Monte Carlo approach) to the coarsest one. In the continuation algorithm (C-MLMC) the parameters that control the number of levels and realizations per level are computed on the y to further reduce the overall computational cost. The C-MLMC is applied to the quasi 1D convergent-divergent Laval nozzle and the 2D transonic RAE-2822 airfoil.

description: We investigate the thermoelectric effect for baryon rich plasma produced in heavy ion collision experiments. We estimate the associated Seebeck coefficient for the hadronic matter. Using kinetic theory within relaxation time approximation we calculate the Seebeck coefficient of a hadronic medium with a temperature gradient. The calculation is performed for hadronic matter modeled by hadron resonance gas model with hadrons and resonance states up to a cutoff in the mass as 2.25 GeV. We argue that the thermoelectric current produced by such effect can produce magnetic field in heavy ion collision experiments.

description: Due to its long-lasting tranquilizing effect on the human body, the abusive use of flunitrazepam (FNZ) in sexual assault and robbery is commonly encountered. In this study, the assembly of a hybrid nanocomposite comprising cerium oxide (CeO2) nanoparticles and reduced graphene oxide (rGO) nanosheets onto the surface of a screen printed carbon electrode (SPCE) is presented for the sensitive determination of flunitrazepam in various beverages. The properties of the CeO2-rGO nanocomposite were evaluated using various spectroscopic and microscopic techniques, while its electrochemical properties were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). A distinct composite structure with improved current response and electron transfer properties was achieved through the judicious application of rGO nanosheets to facilitate the in situ formation and anchoring of CeO2 nanoparticles. Under optimal conditions, the CeO2-rGO modified SPCE demonstrated flunitrazepam detection to 124 nM with a sensitivity of 40 µA µM−1 cm−2 and exhibited a broad linear response in the concentration range from 0.1 to 300 µM. The quantification of flunitrazepam in spiked beverage samples using CeO2-rGO/SPCE demonstrated satisfactory recovery from 96 to108%. The functionalized sensor was further integrated into a microfluidic chip to prepare a portable flunitrazepam electrochemical platform, in which multiple samples can be processed and reliable analysis can be conducted at low sample volumes. The designed electrochemical microfluidic platform demonstrated desirable performance for flunitrazepam determination, offering a promising solution for on-site determination of illicit drugs in the field of forensic investigations.

description: Die Urteile über die sozial-emotionalen Kompetenzen von Kindern mit Verhaltensauffälligkeiten unterscheiden sich zwischen Eltern und Lehrpersonen. Die Ursachen für die Urteilsunterschiede wurden bisher wenig untersucht. Verschiedene Studien zeigen, dass die Urteile mit den Ergebnissen von standardisierten Entwicklungstests schwach korrelieren. Zusätzlich besteht ein Zusammenhang zwischen den sozial-emotionalen Kompetenzen der Kinder und der Lehrperson-Schüler:in-Beziehung bzw. der Empathie der Eltern. Es wird der Frage nachgegangen, wie übereinstimmend Eltern und Lehrpersonen die sozial-emotionalen Kompetenzen beurteilen und wie die Lehrperson-Schüler:in-Beziehung bzw. die Empathie der Eltern diese Urteilsunterschiede erklären. Ausgewertet wurden querschnittliche Fragebogendaten, welche die Einschätzungen von Eltern und Lehrpersonen zu N = 158 Kindern mit Verhaltensauffälligkeiten aus dem Kindergarten sowie der Grundschule enthielten. Alle Urteile der Lehrpersonen korrelierten mit den Ergebnissen des Entwicklungstests, während nur ein Teil der Urteile der Eltern damit zusammenhing. Moderierte Regressionsanalysen zeigen, dass Eltern die sozial-emotionalen Kompetenzen der Kinder mit Verhaltensauffälligkeiten höher einschätzten als Lehrpersonen. Mit einer besseren Lehrperson-Schüler:in-Beziehung näherten sich die Urteile von Eltern und Lehrpersonen an, mit einer höheren Empathie der Eltern wurden die Urteilsunterschiede grösser. Die Ergebnisse widerspiegeln die Wichtigkeit, die Beurteilung von sozial-emotionalen Kompetenzen in der Aus- und Weiterbildung von Lehrpersonen zu thematisieren.

description: The Eddington-inspired Born-Infeld (EiBI) gravity is a modification of the theory of general relativity inspired by the nonlinear Born-Infeld electrodynamics. The theory is described by a series of higher curvature terms added to the Einstein-Hilbert action with the parameter $κ$. The EiBI gravity has several interesting exact neutral and charged black hole solutions. We study the problem of overcharging extremal black hole solutions of EiBI gravity using a charged test particle to create naked singularity. We show that unlike general relativity, the overcharging could be possible for a charged extremal black hole in EiBI gravity as long as the matter sector is described by usual Maxwell's electrodynamics. Once the matter sector is also modified in accordance to the Born-Infeld prescription with the parameter $b$, the overcharging is not possible as long as the parameters obey the condition $4 κb^2 \leq 1$.
