description: In the past decade, significant progress has been made in the acquisition and processing of seismic wavefield gradient data (e.g., recordings of ground strain and rotation). When combined with conventional multicomponent seismic data, wavefield gradients enable the estimation of local wavefield properties (e.g., the local wave speed, the propagation direction, and the wave type) and the reconstruction of spatially under-sampled seismic wavefields. However, the seismological community has yet to embrace wavefield gradient data as a new observable.

We present TwistPy (Toolbox for Wavefield Inertial Sensing Techniques), an open-source software package for seismic data processing written in Python. It includes routines for single-station polarization analysis and filtering, as well as array processing tools. A special focus lies on innovative techniques to process spatial wavefield gradient data and, in particular, rotational seismic data obtained from dedicated rotational seismometers or small-aperture arrays of three-component sensors. Routines currently included in the package comprise polarization analysis and filtering in both the time domain and the time-frequency domain (for three-component and six-component data), dynamic tilt corrections, and beamforming (Bartlett, Capon, and MUSIC beamformers).  

With TwistPy, we attempt to lower the barrier of entry for the seismological community to use state-of-the art multicomponent and wavefield gradient analysis techniques by providing a user-friendly software interface.

description: Probabilistic programming languages (PPLs) are expressive means for creating and reasoning about probabilistic models. Unfortunately hybrid probabilistic programs, involving both continuous and discrete structures, are not well supported by today's PPLs. In this paper we develop a new approximate inference algorithm for hybrid probabilistic programs that first discretizes the continuous distributions and then performs discrete inference on the resulting program. The key novelty is a form of discretization that we call bit blasting, which uses a binary representation of numbers such that a domain of $2^b$ discretized points can be succinctly represented as a discrete probabilistic program over poly($b$) Boolean random variables. Surprisingly, we prove that many common continuous distributions can be bit blasted in a manner that incurs no loss of accuracy over an explicit discretization and supports efficient probabilistic inference. We have built a probabilistic programming system for hybrid programs called HyBit, which employs bit blasting followed by discrete probabilistic inference. We empirically demonstrate the benefits of our approach over existing sampling-based and symbolic inference approaches.

title: Filmtechnische Strategien zur akustischen und visuellen Darstellung von Gedanken und Gefühlen in Filmen von Cristina und Francesca Comencini sowie Nanni Moretti
Creators: name: John, Margot
Year: 2012

description: Für die emotionale Filmgestaltung ist es wichtig, wie die Kamera das Geschehen festhält. Hier gilt es zwischen dem Blickwinkel, der Bildschärfe und der jeweiligen Einstellungsgröße zu unterscheiden. Als Montage versteht man die Aneinanderreihung der einzelnen Bilder mithilfe von Schnitten oder Überblendungen. Die Filme der Comencini Schwestern unterliegen einer linearen und parallelen Erzählstruktur, während Morettis Film seine Chronologie dank der Tonspur erhält. Die Sympathie oder Antipathie des Zuschauers für eine Figur und die Darstellung des Raums werden, neben der Bildkomposition und Kameratechniken, durch markante Licht- und Schatteneffekte erzielt. Die spannungsgeladenen Momente werden durch die musikalische Begleitung aus dem Off verstärkt. In ausgewählten Filmsequenzen werden die Techniken der Filmgestaltung beleuchtet, um dann auf die Vorgehensweisen jedes einzelnen Regisseurs im Resümee einzugehen. Zusammenfassend ist festzustellen, dass die Comencinis die einzelnen Szenen mit aufwändigen Kameratechniken emotionalisieren, während Morettis Figuren den Zuschauer aufgrund ihrer humorvollen oder ernsten Mimik fesseln. Zur Darstellung von Erinnerungen und Wünschen verwendet Cristina Comencini Zeit- und Raumsprünge oder Fernsehbilder. Francesca Comencini drückt die Gedanken ihrer Figuren mithilfe der synchronen Sprache oder leitmotivischer Musik aus. Giovanni Moretti erläutert seine Gedanken in synchronen und asynchronen Monologen oder surrealen Dialogsituationen.

Enhancement of Seismic Phase Identification using Polarization Filtering and Array Analysis

description: Single-station polarization analysis allows us to extract wave parameters, such as inclination, azimuth, and ellipticity angle, directly from a recorded seismic signal theoretically. In reality, however, seismic data are not purely polarized in the finite analysis window due to varying noise levels, complex wavefield interactions, and calibration errors. Hence, this would potentially influence the observation window of phases of interest. In order to minimize these systematic errors, the involvement of arrays and array processing techniques can further increase the signal-to-noise ratio of coherent signals in a wavefield, which allows us to identify different seismic phases, especially the weaker phases that are usually difficult to observe in a single waveform, even after filtering for a desired wave type. In this study, we present a new approach that combines polarization analysis and filtering in the time-frequency domain using the S-transform with conventional array analysis such as beamforming to enhance seismic signals and distinguish different phases based on their expected slownesses and backazimuth. We apply this approach on AlpArray data and demonstrate wavefield separation in vespagrams using various polarization filters. We also discuss the benefits of our approach especially on small amplitude inner core phases (e.g., PKIKPPKIKP) and their applications for advancing seismological study of Earth’s inner core.

description: Storing carbon in the deep ocean is a key-feedback mechanism that allows astronomical forcing to drive the late Pleistocene glacial/interglacial variations. As carbon storage is intrinsically linked to oxygenation, proxies for sediment oxygenation have been used to quantify changes in carbon storage during the late Pleistocene. However, evidence for astronomically-paced changes in carbon storage beyond the late Pleistocene is limited, hindering our understanding of the stability of this feedback mechanisms.

Here we used molecular fossils (biomarkers) in marine sediment cores that span the last ~3.5 million years to assess the long-term impact of astronomical forcing on deep ocean oxygenation, and hence carbon storage, and explore the stability of this deep ocean feedback mechanism. Using high-resolution records from three independent cores from the North Atlantic, we find that the concentration of biomarkers from anaerobic bacteria is eccentricity paced during the middle and late Pleistocene with high abundances during glacials and absence during interglacials. We interpret this data to reflect a decrease in oxygenation and hence increase in carbon storage during the most recent glacials. Across the MPT this pacing changes to obliquity forcing and we show that this forcing is persistent into the late Pliocene, highlighting the stability of this feedback mechanism. However, prior to 2.7 Myr we find no biomarkers of anaerobic bacteria across the North Atlantic, suggesting reduced carbon storage prior to the intensification of the glaciation of the Northern Hemisphere. Our findings indicate that the lowering of atmospheric CO2 by the sequestration of carbon in the deep ocean in response to astronomical forcing persisted throughout the Quaternary and was essential for the development of Plio/Pleistocene ice ages, but this feedback mechanisms did not persist into the warm Pliocene.

description: The dynamical Casimir effect is the physical phenomenon where the mechanical energy of a movable wall of a cavity confining a quantum field can be converted into quanta of the field itself. This effect has been recognized as one of the most astonishing predictions of quantum field theory. At the quantum scale, the energy conversion can also occur incoherently, namely without an physical motion of the wall. We employ quantum thermodynamics to show that this phenomenon can be employed as a tool to cool down the wall when there is a non-vanishing temperature gradient between the wall and the cavity. At the same time, the process of heat-transfer enables to share the coherence from one cavity mode, driven by a laser, to the wall, thereby forcing its coherent oscillation. Finally, we show how to employ one laser drive to cool the entire system including the case when it is composed of other subsystems.

They are implied by the large size asymptotic analysis of exact Pfaffian identities for expectation values of ratios of characteristic polynomials in ensembles of orthogonal or quaternionic self-dual random matrices. We show that they amount to identities for the theta function with the period matrix of a hyperelliptic curve, and in this form we reprove them by direct geometric methods.

description: We develop a novel framework for describing quantum fluctuations in field theory, with a focus on cosmological applications. Our method uniquely circumvents the use of operator/Hilbert-space formalism, instead relying on a systematic treatment of classical variables, quantum fluctuations, and an effective Hamiltonian. Our framework not only aligns with standard formalisms in flat and de Sitter spacetimes, which assumes no backreaction, demonstrated through the $φ^3$-model, but also adeptly handles time-dependent backreaction in more general cases. The uncertainty principle and spatial symmetry emerge as critical tools for selecting initial conditions and understanding effective potentials. We discover that modes inside the Hubble horizon \emph{do not} necessarily feel an initial Minkowski vacuum, as is commonly assumed. Our findings offer fresh insights into the early universe's quantum fluctuations and potential explanations to large-scale CMB anomalies.

description: We prove analytically the ballistic thermal rectification effect (BTRE) in the Corbino disk characterized by an annular shape. We derive the thermal rectification efficiency (RE) and show that it can be expressed as the product of two independent functions, the first dependent on the temperatures of the heat baths and the second on the system's geometry. It follows that a perfect BTRE can be reached with the increase of the ratios of the heat baths' temperatures and of the radius of the outer edge to the inner edge of the disk. We also show that, by introducing a potential barrier into the Corbino disk, the RE can be greatly improved. Quite remarkably, by an appropriate choice of parameters, the thermal diode effect can be reversed. Our results are robust under variation of the Corbino geometry, which may provide a novel and flexible route to manipulate the heat flow at the nanoscale.

Evaluation of RANS-based turbulence models for isothermal flow in a realistic can-type gas turbine combustor application

Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The present study assesses RANS-based turbulence models to simulate isothermal flow in a combustor representing a constituent can combustor of can-annular configuration used in jet engines. Two-equation models (standard $k-ε$, realizable $k-ε$, standard $k-ω$, SST $k-ω$), and Linear Pressure Strain - Reynolds Stress Model (LPS-RSM), are assessed by comparing their predictions of mean axial and transverse velocity, turbulent kinetic energy, and shear stress with the experimental data at the primary and dilution hole planes in combustor. While the two-equation models generally have failed to predict the confined swirling flow at both positions accurately, the SST $k-ω$ model yielded the most accurate, followed by standard $k-ω$ and realizable $k-ε$ models. The discrepancies between the computational and experimental results could be attributed to the isotropic turbulence assumptions, which, however, are invalid for confined swirling flows. Further, the two-equation model formulations cannot capture the intricacies of vortex flow and its interaction with the surroundings in confined swirling flows. LPS-RSM, which considers turbulence anisotropy, showed some promise, although overpredicted results follow the trend with experimental values at the primary holes plane. However, at dilution holes plane, the model overpredicted the velocity field and underestimated turbulence field, including turbulent kinetic energy and shear stress. These observed discrepancies can be ascribed to the pressure-strain correlation in the LPS-RSM, which assumes the pressure is a linear function of the strain-rate tensor. However, for complex flows, this linear assumption is quite simplistic. Hence, this study suggests that more advanced turbulence models such as non-LPS-RSM are needed to accurately predict the confined swirling flow in combustors.

CFD analysis of the influence of contraction size on electroviscous flow through the slit-type non-uniform microfluidic device

Year: 2023
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The electroviscous effects are relevant in controlling and manipulating the fluid, thermal, and mass transport microfluidic processes. The existing research has mainly focused on the fixed contraction ratio ($d_\text{c}$, i.e., the area ratio of contraction to expansion) concerning the widely used contraction-expansion geometrical arrangement. This study has explored the influence of the contraction ratio ($d_\text{c}$) on the electroviscous flow of electrolyte liquids through the charged non-uniform microfluidic device. The numerical solution of the mathematical model (Poisson's, Nernst-Planck, and Navier-Stokes) using a finite element method (FEM) yields the local flow fields. In general, the contraction ratio significantly affects the hydrodynamic characteristics of microfluidic devices. The total electrical potential and pressure drop maximally increase by {1785\% and 2300\%}, respectively, with an overall contraction ratio ($0.25\le d_\text{c}\le 1$). Further, an electroviscous correction factor ($Y$, i.e., the ratio of apparent to physical viscosity) maximally enhances by 11.24\% (at $K=8$, $S=16$ for $0.25\le d_\text{c}\le 1$), 31.80\% (at $S=16$, $d_\text{c}=0.75$ for $2\le K\le 20$), 22.89\% (at $K=2$, $d_\text{c}=0.5$ for $4\le S\le 16$), and 46.99\% (at $K=2$, $d_\text{c}=0.75$ for $0\le S \le 16$). The present numerical results may provide valuable guidelines for the performance optimization and design of reliable and essential microfluidic devices.

Drainage divide asymmetry as an indicator of large-scale landscape transience on the Southeast Tibetan Plateau
Creators: name: Gelwick, Katrina
name: Willett, Sean D.
name: Wang, Yanyan
Publisher: name: ETH Zurich
Year: 2023

description: Landscapes are sculpted by a complex response of surface processes to external forcings, such as climate and tectonics. Several major stream captures have been documented on the Southeast Tibetan Plateau, leading to the hypothesis that the region experiences exceptionally high rates of drainage reorganization driven by horizontal shortening and propagating uplift. Here we determine the prevalence, intensity, and spatial patterns of ongoing drainage reorganization on the Southeast Tibetan Plateau and evaluate the relative time scales of this transience by comparing drainage divide asymmetry for four geomorphic metrics that operate at different spatial and temporal scales. Specifically, we evaluate drainage divide asymmetry in catchment-restricted topographic relief, hillslope gradient, normalized channel steepness (ksn), and χ. ksn and χ are both precipitation-corrected to account for the strong precipitation gradient across the region. We calculate the migration direction and Scherler & Schwanghart (2020)’s divide asymmetry index (DAI) in each metric for drainage divides across the entire region in order to analyze how well the asymmetry in these metrics agree along divides and where consistent divide movement is inferred. We find a high incidence of strongly asymmetric divides in all metrics across the entire Southeast Tibetan Plateau. While the magnitude of asymmetry varies significantly between metrics, a majority of divides agree on divide migration direction across all metrics. Divides with higher magnitudes of asymmetry are more likely to agree on migration direction across multiple metrics. While χ agrees least often with the other metrics on migration direction, it agrees on direction >90% of the time when low DAI divides are excluded. We also establish that disagreement in predicted divide migration directions between χ and the other geomorphic metrics can be interpreted as evidence of localized variations in tectonic uplift or erodibility, glacial alteration, or recent lateral stream capture. Our work confirms the high incidence of drainage reorganization across the Southeast Tibetan Plateau and highlights both transient and stable areas in the landscape with unprecedented resolution. In addition, we propose how to combine geomorphic metrics to ascertain how drainage divides migrate across different timescales and identify local deviations in tectonic uplift and erodibility.

description: Climate change is amplified in the arctic and boreal regions. This causes higher average temperatures and less precipitation in the summer months and is resulting in longer wildfire seasons, severity, frequency and extent. This increases the relies of carbon into the atmosphere as greenhouse gases and aerosols, amplifying climate change even further. Black carbon (BC) is a fraction of organic carbon, resulting from the incomplete combustion of biomass and fossil fuels. BC may be inaccessible for biodegradation, because of its highly condensed aromatic molecular structure and therefore stores carbon on long timescales on land and in the ocean. BC is produced on land, but is transported as dissolved BC (DBC) by the rivers to the oceans, where it cycles on millennial timescales, sequestering BC. Thus, it is important to understand the significance of BC in the context of increased fires in this vulnerable region in the face of climate change.
The Mackenzie River is a major source of terrestrial dissolved organic carbon (DOC) and the largest source of sediments to the Arctic Ocean. Here, we resolve the cycling of riverine DBC from the Mackenzie River to its fate in the Beaufort Sea, and the influence of mixing with Pacific water masses entering from the Chukchi Sea. We present DBC concentration data in ocean water, which was collected on two cruises in the Beaufort Sea in 2021 and 2022 covering the outflow of the Mackenzie River. 
For DBC concentrations, we digested solid phase extracts of DOC with nitric acid to oxidize BC molecules into benzenepolycarboxylic acids (BPCAs), which were then quantified on High Performance Liquid Chromatography (HPLC). We compare the concentrations of the DBC and DOC to trace the mixing of DBC river outflow with the ocean water. Since DBC originates on land and is relatively stable to biodegradation we can resolve the pathways of DBC from the Mackenzie River to the Arctic Ocean.

description: В технологии возделывания сельскохозяйственных культур без обработки почвы (технология No-till) очень важно, чтобы физические свойства почвы не ухудшались, а были в оптимальных значениях для роста и развития возделываемых растений в течение длительного времени. Одним из важнейших показателей агрофизических свойств почвы является её плотность, от которой зависят водно-воздушные, тепловые и биологические свойства почвы, а также её водопроницаемость, водоудерживающая способность, распространение корней и создание условий для произрастания возделываемых растений и их урожайности.
В связи с этим целью наших исследований является определение динамики плотности почвы в течение 6 лет при возделывании сельскохозяйственных культур без обработки почвы в севообороте на чернозёме обыкновенном зоны неустойчивого увлажнения Ставропольского края.

description: Представлены результаты исследований по изучению влияния технологии без обработки почвы (No-till), а также разных доз минеральных удобрений на полевую всхожесть растений озимой пшеницы в сравнении с традиционной технологией. Установлена высокая эффективность минеральных удобрений при возделывании озимой пшеницы по обеим технологиям, так как их внесение приводит к повышению полевой всхожести семян озимой пшеницы, но по технологии No-till, количество взошедших растений достоверно больше.

description: Image-Text pretraining on web-scale image caption dataset has become the default recipe for open vocabulary classification and retrieval models thanks to the success of CLIP and its variants. Several works have also used CLIP features for dense prediction tasks and have shown the emergence of open-set abilities. However, the contrastive objective only focuses on image-text alignment and does not incentivise image feature learning for dense prediction tasks. In this work, we propose the simple addition of local-to-global correspondence learning by self-distillation as an additional objective for contrastive pre-training to propose SILC. We show that distilling local image features from an exponential moving average (EMA) teacher model significantly improves model performance on several computer vision tasks including classification, retrieval, and especially segmentation. We further show that SILC scales better with the same training duration compared to the baselines. Our model SILC sets a new state of the art for zero-shot classification, few shot classification, image and text retrieval, zero-shot segmentation, and open vocabulary segmentation.

Light Source Estimation via Intrinsic Decomposition for Novel View Synthesis
Creators: name: Tetruashvili, David Simon
Publisher: name: ETH Zurich
Year: 2023

description: In this thesis, we propose a method for light source estimation via intrinsic decomposition within a Neural Radiance Field-like setting. We begin by exploring a learned method to recover light sources from intrinsic components - reflectance, shading, and surface normals. As demonstrated, the learned mapping is unable to properly learn the relationship between the different intrinsic components, and instead overfits some components while ignoring the rest. However, inference of local SH lighting, while somewhat spatially discontinuous, shows promise for future extensions. For these reasons, we later pivot our approach to directly optimize global spherical harmonics lighting, in which the in-scene radiance is represented by coefficients of a single global basis function. With this optimization-based approach, we successfully reconstruct a coarse estimate of the lighting of our scenes. To validate and support our method, we introduce a novel synthetic dataset, which consists of intrinsic components of several scenes. For each scene in our dataset, we provide geometry, shading, reflectance, and fully diffuse and rendered passes. We hope that extensions of our work could serve as modules of future NeRF models, enabling the joint optimization and refinement of lighting, geometry, and radiance.

description: With the end of Moore's Law and the increasing demand for computing, photonic accelerators are garnering considerable attention. This is due to the physical characteristics of light, such as high bandwidth and multiplicity, and the various synchronization phenomena that emerge in the realm of laser physics. These factors come into play as computer performance approaches its limits. In this study, we explore the application of a laser network, acting as a photonic accelerator, to the competitive multi-armed bandit problem. In this context, conflict avoidance is key to maximizing environmental rewards. We experimentally demonstrate cooperative decision-making using zero-lag and lag synchronization within a network of four semiconductor lasers. Lag synchronization of chaos realizes effective decision-making and zero-delay synchronization is responsible for the realization of the collision avoidance function. We experimentally verified a low collision rate and high reward in a fundamental 2-player, 2-slot scenario, and showed the scalability of this system. This system architecture opens up new possibilities for intelligent functionalities in laser dynamics.

description: The notion of $α$-equivalence between $λ$-terms is commonly used to identify terms that are considered equal. However, due to the primitive treatment of free variables, this notion falls short when comparing subterms occurring within a larger context. Depending on the usage of the Barendregt convention (choosing different variable names for all involved binders), it will equate either too few or too many subterms. We introduce a formal notion of context-sensitive $α$-equivalence, where two open terms can be compared within a context that resolves their free variables. We show that this equivalence coincides exactly with the notion of bisimulation equivalence. Furthermore, we present an efficient $O(n\log n)$ runtime hashing scheme that identifies $λ$-terms modulo context-sensitive $α$-equivalence, generalizing over traditional bisimulation partitioning algorithms and improving upon a previously established $O(n\log^2 n)$ bound for a hashing modulo ordinary $α$-equivalence by Maziarz et al. Hashing $λ$-terms is useful in many applications that require common subterm elimination and structure sharing. We have employed the algorithm to obtain a large-scale, densely packed, interconnected graph of mathematical knowledge from the Coq proof assistant for machine learning purposes.

description: Power Electronics is a key technology for all forms of generation and utilization of electric power in modern societies, ranging from renewable energy systems and highly diverse power supply applications including fast charging of EVs and hyper-scale datacenters to variable frequency drives for industrial automation. The progress in the area has been driven over the past 40 years by new power semiconductor device concepts and corresponding circuit topologies with a focus on voltage-source converter (VSC) structures and/or the application of switching elements limited to unipolar voltage-blocking capability. With reference to recently intensifying R&D activities on two-gate monolithic bi-directional switches (M-BDSs) featuring bipolar voltage blocking and bidirectional current control capability, the talk highlights the potential advantages of M-BDSs for the realization of ultra-compact non-isolated and isolated three-phase PFC rectifier systems and next generation inverter systems with low motor insulation stress. In this context, the performance gains achievable utilizing three level T-type VSC topologies, new Solid-State-Transformer structures, and the unique features of current-source converter approaches – today solely employed in thyristor-based high-power medium-voltage motor drives - and AC/AC matrix converter concepts over state-of-the-art VSC systems are emphasized. Final considerations are on the paramount importance of minimization of life-cycle environmental impacts and/or ensuring circular economy compatibility of future power electronics systems for the next disruptive performance improvement towards Power Electronics 5.0.
