Stochastic simulators

description: Computational models, a.k.a. simulators, are used in all fields of engineering and applied sciences to help design and assess complex systems. Advanced analyses such as optimization or uncertainty quantification, which require repeated runs by varying input parameters, cannot be carried out with brute force methods such as Monte Carlo simulation due to computational costs. Thus the recent development of surrogate models such as polynomial chaos expansions and Gaussian processes, among others.  For so-called stochastic simulators used e.g.~in epidemiology, mathematical finance or wind turbine design, there exists an intrinsic source of stochasticity on top of well-identified system parameters. Hence, for a given vector of inputs, repeated runs of the simulator (called replications) will provide different results, as opposed to the case of deterministic simulators. Consequently, for each input realization, the response is a random variable to be characterized.  In this talk we present recent developments in surrogate models for such simulators, which we call stochastic emulators. We first focus on generalized lambda models (GLaM), which combine so-called parametric lambda distributions and polynomial chaos expansions. Stochastic polynomial chaos expansions allows us to address more complex, e.g.  multimodal, output distributions. In both cases, no replicated runs of the simulator are needed. Finally, a spectral approach based on a random field representation can be used when trajectories of the stochastic simulator are available. The various methods will be illustrated with engineering application examples.

Economics

description: When it comes to fighting poverty, the prescription of most economists is growth. This means growth of agriculture in many low-income countries where production of food and various commodity crops remains the biggest employer. There are risks, however – especially for local populations marginalized by rising commercial activity or incorporated into it on adverse terms. Based on evidence from the coffee heartlands of Rwanda and Laos, this policy brief highlights tools for measuring the impacts of agricultural growth on poverty in rural areas. And it emphasizes the oft-overlooked importance of labour dynamics in such settings.

description: In recent years, serverless computing has emerged as a popular cloud computing paradigm, focusing strongly on ease of use and automatic scalability. Serverless computing, such as Amazon Web Services (AWS) Lambda, offers several advantages over traditional cloud computing models: managed infrastructure, auto-scaling and millisecond-level billing, thereby significantly reducing development time and improving cost-efficiency. However, applications still need to be built explicitly for use with the cloud serverless APIs, and existing applications cannot directly run on e.g. AWS Lambda. In this thesis, we explore the feasibility of transparently running arbitrary unmodified programs on serverless computing platforms by intercepting the creation of OS processes and offloading them to the cloud.

OS processes are a common denominator among many programs, which enables us to treat them as opaque. In contrast, existing approaches would either sacrifice transparency and require modifications to user programs or be specifically tailored/optimized to a particular programming language and/or application. Instead, operating at a lower level of abstraction - at the process level - enables both transparency and programming language agnosticism.

We demonstrate our hypothesis by offloading a Python image processing program and compilation build systems. We extend the computational resources of a 16vCPU VM via offloading to speed up an image resizing task by a factor of more than 5 and improve the compilation time of the Inkscape project by more than a factor of 2, respectively.

description: Wind-driven snow redistribution affects the glacier mass balance by eroding or depositing mass from or to different parts of the glacier’s surface. High-resolution observations are used to test the ability of large eddy simulations as a tool for distributed mass balance modeling. We present a case study of observed and simulated snow redistribution over Hintereisferner glacier (Ötztal Alps, Austria) between 6 and 9 February 2021. Observations consist of three high-resolution Digital Elevation Models (∆x=1 m) derived from terrestrial laser scans taken shortly before, directly after, and 15 hours after snowfall. The scans are complemented by data sets from three onsite weather stations. After the snow fall event the snowpack decreased by 0.08 m on average over the glacier and typical snow redistribution patterns were observed. The decrease of the snow depth is to be attributed to both post-snowfall compaction and redistribution of snow. Simulations were performed with the WRF model at ∆x=48 m with a newly implemented snow drift module. The spatial patterns of the simulated snow redistribution agree well with the observed generalized patterns. Snow redistribution contributed -0.026 m to the surface elevation decrease over the glacier surface on 8 Feb, resulting in a mass loss of -3.9 kg m−2, which is in the same order of magnitude as the observations. With the single case study we cannot yet extrapolate to the impact of post-snowfall events on the seasonal glacier mass balance, but the study shows that the snow drift module in WRF is a powerful tool to improve knowledge on snow redistribution over glaciers and that the model setup can be applied to other mountain glaciers.

description: A new formalism for thermodynamics of AdS black holes called the {\em restricted phase space thermodynamics} (RPST) is proposed. The construction is based on top of Visser's holographic thermodynamics, but with the AdS radius fixed as a constant. Thus the RPST is free of the $(P,V)$ variables but inherits the central charge and chemical potential as a new pair of conjugate thermodynamic variables. In this formalism, the Euler relation and the Gibbs-Duhem equation hold simultaneously with the first law of black hole thermodynamics, which guarantee the appropriate homogeneous behaviors for the black hole mass and the intensive variables. The formalism is checked in detail in the example case of 4-dimensional RN-AdS black hole in Einstein-Maxwell theory, in which some interesting thermodynamic behaviors are revealed.

description: Superconducting high entropy alloy (HEA) are emerging as a new class of superconducting materials. It provides a unique opportunity to understand the complex interplay of disorder and superconductivity. We report the synthesis and detail bulk and microscopic characterization of Nb$_{60}$Re$_{10}$Zr$_{10}$Hf$_{10}$Ti$_{10}$ HEA alloy using transport, magnetization, specific heat, and muon spin rotation/relaxation ($μ$SR) measurements. Bulk superconductivity with transition temperature $T_{C}$ = 5.7 K confirmed by magnetization, resistivity, and heat capacity measurements. Zero-field $μ$SR measurement shows that the superconducting state preserves time-reversal symmetry, and transverse-field measurements of the superfluid density are well described by an isotropic s-wave model.

description: Using a random temporal signal for sample excitation (RATS method) is a new, efficient approach to measuring photoluminescence (PL) dynamics. The method can be used in single-point measurement (0D), but also it can be converted to PL decay imaging (2D) using a single-pixel camera configuration. In both cases, the reconstruction of the PL decay and PL snapshot is affected by ubiquitous noise. This article provides a detailed analysis of the noise effect on the RATS method and possible strategies for its elimination. We carried out an extensive set of simulations focusing on the effect of noise introduced through the random excitation signal and the corresponding PL waveform. We show that the PL signal noise level is critical for the method. Furthermore, we analyze the role of acquisition time, where we demonstrate the need for a non-periodic excitation signal. We show that it is beneficial to increase the acquisition time while increasing the number of measurements in the single-pixel camera configuration has a minimal effect above a certain threshold. Finally, we study the effect of a regularization parameter used in the deconvolution step, and we observe that there is an optimum value set by the noise present in the PL dataset. Our results provide a guideline for optimization of the RATS measurement, but also study effects generally occurring in PL decay measurements methods relying on the deconvolution step.

description: The scattering matrix which describes low-energy, non-relativistic scattering of spin-1/2 fermions interacting via finite-range potentials can be obtained from a geometric action principle in which space and time do not appear explicitly arXiv:2011.01278. In the case of zero-range forces, causality leads to constraints on scattering trajectories in the geometric picture. The effect of spatial dimensionality is also investigated by considering scattering in two and three dimensions. In the geometric formulation it is found that dimensionality is encoded in the phase of the harmonic potential that appears in the geometric action.

description: The evolution of massive stars is the basis of several astrophysical investigations, from predicting gravitational-wave event rates to studying star-formation and stellar populations in clusters. However, uncertainties in massive star evolution present a significant challenge when accounting for these models' behaviour in stellar population studies. In this work, we present a comparison between five published sets of stellar models from the BPASS, BoOST, Geneva, MIST, and PARSEC simulations at near-solar metallicity. The different sets of stellar models have been computed using slightly different physical inputs in terms of mass-loss rates and internal mixing properties. Moreover, these models also employ various pragmatic methods to overcome the numerical difficulties that arise due to the presence of density inversions in the outer layers of stars more massive than 40 M$_\odot$. These density inversions result from the combination of inefficient convection in the low-density envelopes of massive stars and the excess of radiative luminosity to the Eddington luminosity. We find that the ionizing radiation released by the stellar populations can change by up to 18 percent, the maximum radial expansion of a star can differ between 100-1600 R$_\odot$, and the mass of the stellar remnant can vary up to 20 M$_\odot$ between the five sets of simulations. We conclude that any attempts to explain observations that rely on the use of models of stars more massive than 40 M$_\odot$ should be made with caution.

description: Background: As clinical genetics advances, we learn more about genetics and genomics, which may be relevant for patients. This makes recontacting more important. Recontacting entails that new contact is established with former patients to pass on new genetic information. Recontacting involves many stakeholders, but there is no overview of the stakeholder landscape. This document is the protocol for a stakeholder analysis of recontacting in clinical genetics in the Netherlands.

Methods: Dutch stakeholders are identified by searching for website pages on Google that mention or discuss recontacting in clinical genetics. Textual information from these website pages is collected and synthesized using textual narrative synthesis. Dutch stakeholders are categorized on the basis of actor-linkage analysis and influence-interest analysis.

description: Understanding the connection between nuclear activity and galaxy environment remains critical in constraining models of galaxy evolution. By exploiting extensive catalogued data from the Galaxy and Mass Assembly (GAMA) survey, we identify a representative sample of 205 quasars at 0.1 < z < 0.35 and establish a comparison sample of galaxies, closely matched to the quasar sample in terms of both stellar mass and redshift. On scales <1 Mpc, the galaxy number counts and group membership of quasars appear entirely consistent with those of the matched galaxy sample. Despite this, we find that quasars are ~1.5 times more likely to be classified as the group center, indicating a potential link between quasar activity and cold gas flows or galaxy interactions associated with rich group environments. On scales of ~a few Mpc, the clustering strength of both samples are statistically consistent and beyond 10 Mpc we find no evidence that quasars trace large scale structures any more than the galaxy control sample. Both populations are found to prefer intermediate-density sheets and filaments to either very high- or very low- density environments. This weak dependence of quasar activity on galaxy environment supports a paradigm in which quasars represent a phase in the lifetime of all massive galaxies and in which secular processes and a group-centric location are the dominant trigger of quasars at low redshift.

description: The Lightning Network (LN) is a widely-adopted peer-to-peer network that not only addresses Bitcoin's scaling problem but also enables private payments. LN uses a sophisticated onion encryption and routing scheme to ensure the anonymity of the payer and the payee, as well as the secrecy of the payment amount. Recent work has shown that an application-level attacker can hijack payment routes and use the resulting central position to deanonymize the sender and the receiver of a payment. However, these attacks are visible or require a significant fraction of parties to collude. This paper presents a stealthier, passive network-level attack exploiting the joint centralization of the LN at the application and at the network layers. Five autonomous systems can thus see the traffic of up to 80% of all observable communication channels and infer ongoing payments -- even though the traffic is encrypted, and many participants use Tor to hide themselves. The comprehensive view allows the attacker not only to estimate the value of a payment but also to effectively reduce the anonymity size of its endpoints. We show that this deanonymization attack, which we call Revelio, is practical in today's topology of LN and its underlying infrastructure: Our attack perfectly deanonymizes the senders or the receiver in almost one-third of tested payments.

description: We find a class of twisted and differentially rotating neutron star magnetospheres that do not have a light cylinder, generate no wind and thus do not spin-down. The magnetosphere is composed of embedded differentially rotating flux surfaces, with the angular velocity decreasing as $Ω\propto 1/r$ (equivalently, becoming smaller at the foot-points closer to the axis of rotation). For each given North-South self-similar twist profile there is a set of self-similar angular velocity profiles (limited from above) with a "smooth", dipolar-like magnetic field structure extending to infinity. For spin parameters larger than some critical value, the light cylinder appears, magnetosphere opens up, and the wind is generated.

description: A dilute gas of hard disks confined between two straight parallel lines is considered. The distance between the two boundaries is in between one and two particle diameters, so that the system is quasi-one-dimensional. A Boltzmann-like kinetic equation, that takes into account the limitation in the possible scattering angles, is derived. It is shown that the equation verifies an $H$ theorem implying a monotonic approach to equilibrium. The implications of this result are discussed, and the equilibrium properties are derived. Closed equations describing how the kinetic energy is transferred between the degrees of freedom parallel and perpendicular to the boundaries are derived for states that are homogeneous along the direction of the boundaries. The theoretical predictions agree with results obtained by means of molecular dynamics simulations.

By discussing the connection between Goldstone and Gauge theories, we establish that this model effectively computes the partition function of the Schwarzian theory where the $\textrm{SL}(2,\mathbb{R})$ symmetry is realized on the base space. The computation is straightforward, involves a local quantum measure and does not rely on localization arguments. Non-localities in the model are exclusively related to the value of fixed gauge invariant moduli. Furthermore, we study the properties of these models when all degrees of freedom are allowed to fluctuate. We discuss the UV finiteness properties of these systems and the emergence of a Planck's length.

description: TQ 264698. Excavations following a resistivity survey on a site adjacent to that of the Augustinian Priory of St Mary, Merton, revealed a late 14th cent roadway partly overlain by a floor of c 1500. The whole was covered by a destruction layer dating from the demolition, which started in 1538, of the main Priory buildings. The site was crossed by two early 18th cent irrigation ditches. A small stratified sequence of medieval pottery was recovered, and derived material in a layer formed during the destruction of the Priory included pottery, bone and metal. Several documentary references are noted, including a 14th cent possible reference to hunting by the Canons, borne out by finds of fallow deer bones. A tentative date of c 1325-1500 is suggested for the Cheam series of pottery. There is also a report on the mollusca. Au(amp)

description: World Quantum Theory: A Unified Framework for Quantum and Classical Physics Based on Frequency

The propagation speed of photons in a vacuum is commonly assumed to be a constant c, which serves as the foundation for numerous classical and quantum physical theories. However, its applicability under complex energy fields, such as gravitational or electromagnetic fields, remains an area of ongoing debate. This paper introduces the "World Quantum" theory, proposing that photons are composed of fundamental energy units called "World Quanta." The theory suggests that the frequency of the World Quantum's "Internal-Rotation" (inherent at the speed of light c) provides a baseline for energy, while "Macro-Rotation" (the path influenced by external fields) governs the photon’s trajectory and momentum.

The theory introduces the concept of the "World Factor" (Φw), a new parameter that quantifies the effects of external energy fields on photon path bending, allowing for a revised photon energy formula. Notably, the theory includes a negative feedback mechanism that prevents infinite energy growth as a particle’s speed approaches c, addressing the paradox in relativity, which asserts that infinite energy is required for an object to reach light speed.

This unified framework offers new insights into photon behavior, energy, momentum, and mass in complex environments, resolving inconsistencies observed under extreme conditions, such as in strong gravitational fields. While experimental validation remains a goal, potential experimental schemes are proposed to test the theory’s core predictions, providing a pathway for future advancements in understanding the relationship between quantum and classical physics.

We compute analytically the spectrum of the leptonic invariant mass for $B \rightarrow X_c \ell \barν$ up to and including terms of order $1/m_Q^3$ within the HQE at next-to-leading order (NLO) in $α_s$. The full dependence of the differential rate on the mass of the final-state quark is taken into account. We discuss the implications of our results for the precision determination of the CKM matrix element $|V_{cb}|$.

description: The Canonical Polyadic (CP) tensor decomposition is frequently used as a model in applications in a variety of different fields. Using jackknife resampling to estimate parameter uncertainties is often desirable but results in an increase of the already high computational cost. Upon observation that the resampled tensors, though different, are nearly identical, we show that it is possible to extend the recently proposed Concurrent ALS (CALS) technique to a jackknife resampling scenario. This extension gives access to the computational efficiency advantage of CALS for the price of a modest increase (typically a few percent) in the number of floating point operations. Numerical experiments on both synthetic and real-world datasets demonstrate that the new workflow based on a CALS extension can be several times faster than a straightforward workflow where the jackknife submodels are processed individually.
Critical gravitational collapse of a non-minimally coupled scalar field

description: We study the critical gravitational collapse of a massless scalar field non-minimally coupled to gravity, using a quadratic coupling function with a strength parameter $ξ$. We concentrate on critical phenomena of type II, and determine with an accuracy of at least $10^{-12}$ the value of the critical amplitude for collapse to a black hole, as well as the values of the critical and echoing exponents. Obtaining such high accuracy in the critical amplitude requires us to do a coordinate radial transformation that effectively increases resolution near the central regions by a factor of at least $10^3$. As expected, we find that for the case of small coupling the critical behaviour is very similar to that of a minimally coupled scalar field. On the other hand, for high coupling the dynamics become so violent that we need to introduce a special slicing condition, known as the shock-avoiding slicing condition, in order to avoid gauge pathologies that would otherwise cause our simulations to fail. With this new gauge condition we are able to perform high accuracy simulations even in the strong coupling regime, where we find that the critical and echoing exponents become significantly smaller, and that the echoing behavior is richer and can not be modelled by a single harmonic.

description: In this article, we investigate the effect of next-to-the-nearest atom hopping on Klein tunnelling in graphene. An effective quantum dynamics equation is obtained based on an emergent generalized Dirac structure by analyzing the tight-binding model beyond the linear regime. We show that this structure has some interesting theoretical properties. First, it can be used to simplify quantum transport calculations used to characterize Klein tunnelling; second, it is not Chirally symmetric as hinted by previous work. Finally, it is reminiscent of theories on a space with a discrete topology. Exploiting these properties, we show that the discrete topology of the crystal lattice has an effect on the Klein tunnelling, which can be experimentally probed by measuring the transmittance through $n-p-n$ junctions. We argue that this simulates quantum gravitational analogues using graphene and we propose an experiment to perform such measurements.

description: A nanostructured thermoelectric device is designed by connecting a double-barrier resonant tunneling heterostructure to two electron reservoirs. Based on Landauers equation and Fermi-Dirac statistics, the exact solution of the heat flow is calculated. The maximum power output and efficiency are calculated through the optimizations of several key parameters. The optimum characteristic curve of the performance is obtained. The reasonably working region of the device is determined, the selection criteria of main parameters are provided, and the optimum configuration of the device is drawn. Results show that the heterojunction becomes a perfect energy filter by appropriately regulating the chemical potentials of electron reservoirs and optimally choosing the widths of barrier and quantum well and the nanostructured thermoelectric device with resonance tunneling may obtain simultaneously a large power output and a high efficiency.

description: Bidirectional quantum teleportation scheme is a two-way quantum communication process, in which two parties simultaneously receive each other information. Recently, in paper [1] (Zhou et al., IEEE Access, 7, 44269 (2019)), a six-qubit cluster state has been used to teleport three-qubit entangled state (Alice) and arbitrary single-qubit unknown quantum state (Bob) bidirectionally. An experimental point of view, the preparation and the maintenance of cluster type entangled state is very difficult and costly. So, in this paper we have designed an optimal scheme for bidirectional quantum teleportation scheme and shown that proposed scheme requires optimized amount of quantum resources.

description: We construct "soft-collinear gravity", the effective field theory which describes the interaction of collinear and soft gravitons with matter (and themselves), to all orders in the soft-collinear power expansion. Despite the absence of collinear divergences in gravity at leading power, the construction exhibits remarkable similarities with soft-collinear effective theory of QCD (gauge fields). It reveals an emergent soft background gauge symmetry, which allows for a manifestly gauge-invariant representation of the interactions in terms of a soft covariant derivative, the soft Riemann tensor, and a covariant generalisation of the collinear light-cone gauge metric field. The gauge symmetries control both the unsuppressed collinear field components and the inherent inhomogeneity in $λ$ of the invariant objects to all orders, resulting in a consistent expansion.

description: The recent muon $g-2$ result from Fermilab combined with the Brookhaven result, strongly points to new physics beyond the Standard Model which can be well described by the electroweak sector of supersymmetry if the masses of the sleptons and some of the electroweak gauginos are in the few hundred GeV range. However, the Higgs boson mass measurement at 125 GeV indicates a mass scale for squarks which lies in the few TeV region indicating a split mass spectrum between squarks and sleptons. This apparent puzzle is resolved in a natural way in gluino-driven radiative breaking of the electroweak symmetry where radiative breaking is driven by a large gluino mass and the gluino color interactions lead to a large splitting between the squarks and the sleptons. We show that an analysis without prejudice using an artificial neural network also leads to the gluino-driven radiative breaking. We use a set of benchmarks and a deep neural network analysis to test the model for the discovery of light sleptons and sneutrinos at HL-LHC and HE-LHC.

description: 题目 : 世界量子理论:从频率角度看量子和经典物理学的统一框架

摘要传统物理学假设光子传播速度在光速 c 上是恒定的,这构成了许多经典和量子物理理论的基础。然而,这一假设在复杂场(例如引力场或介质)中的适用性仍然存在争议。本文提出了“世界量子”理论,该理论通过区分光子的本征旋转(自旋)和宏观旋转(宏观旋转)来重新研究光子的传播行为。引入了一个关键参数,即“世界因子”(Φw=(c/v)2),将光子能量公式修改为 。在这个框架内,光子的传播速度 v 可能小于光速 c,其波长-频率积也可能小于 c。通过推导和分析,本文统一了量子物理学和经典物理学的理论框架,解释了光子能量、质量和动量的起源,同时为光子在引力场和极端条件下的行为提供了新的视角。虽然目前缺乏实验验证,但我们提出了几种实验方案,通过观察来检验该理论的核心预测。

description: The resonant mode approximation of the scattering matrix is considered for calculating the optical properties of multilayered periodic structures within the formalism of the Fourier-modal method for two diffraction thresholds in close proximity of the spectral-angular range of interest. The developed approximation opens up possibilities for the fast calculation of the scattering matrix of these structures when describing the integral characteristics of spectra and dispersion curves containing high-Q resonances, such as bound states in the continuum.

description: We investigate the predictions of inflation models with a non-minimal coupling to gravity for inflationary observables such as the spectral index and tensor-to-scalar ratio in a general setting. We argue that, depending on the relation between the Jordan frame potential and a function characterizing the non-minimal coupling, one can classify the model into three categories each of which gives distinctive predictions for the inflationary observables. We derive general predictions for each class and also investigate some explicit models to discuss how the general features arise. Our results would be useful to design an inflation model consistent with observational constraints with a non-minimal coupling to gravity.

description: In tri-partite systems, there are three basic biseparability, $A$-$BC$, $B$-$CA$ and $C$-$AB$ biseparability according to bipartitions of local systems. We begin with three convex sets consisting of these basic biseparable states in the three qubit system, and consider arbitrary iterations of intersections and/or convex hulls of them to get convex cones. One natural way to classify tri-partite states is to consider those convex sets to which they belong or do not belong. This is especially useful to classify partial entanglement of mixed states. We show that the lattice generated by those three basic convex sets with respect to convex hull and intersection has infinitely many mutually distinct members, to see that there are infinitely many kinds of three qubit partial entanglement. To do this, we consider an increasing chain of convex sets in the lattice and exhibit three qubit Greenberger-Horne-Zeilinger diagonal states distinguishing those convex sets in the chain.

description: World Quantum Theory: A Unified Framework for Quantum and Classical Physics from a Frequency Perspective

AbstractTraditional physics assumes that the speed of photon propagation is constant at the speed of light c, forming the foundation of many classical and quantum physical theories. However, the applicability of this assumption in complex fields (such as gravitational fields or media) remains contentious. This paper proposes the "World Quantum" theory, which reexamines photon propagation behavior by distinguishing between the photon's intrinsic rotation (self-spin) and macroscopic rotation (macro-rotation). A key parameter, the "World Factor" (Φw=(c/v)2), is introduced, modifying the photon energy formula to . Within this framework, the photon's propagation speed v may be less than the speed of light c, and its wavelength-frequency product may also be less than c. Through derivations and analyses, this paper unifies the theoretical frameworks of quantum and classical physics, explaining the origins of photon energy, mass, and momentum while offering new perspectives on photon behavior in gravitational fields and under extreme conditions. Although experimental validation is currently lacking, we propose several experimental schemes to test the core predictions of this theory through observations.
