description: We study the complexity of high-dimensional approximation in the $L_2$-norm when different classes of information are available; we compare the power of function evaluations with the power of arbitrary continuous linear measurements. Here, we discuss the situation when the number of linear measurements required to achieve an error $\varepsilon \in (0,1)$ in dimension $d\in\mathbb{N}$ depends only poly-logarithmically on $\varepsilon^{-1}$. This corresponds to an exponential order of convergence of the approximation error, which often happens in applications. However, it does not mean that the high-dimensional approximation problem is easy, the main difficulty usually lies within the dependence on the dimension $d$. We determine to which extent the required amount of information changes, if we allow only function evaluation instead of arbitrary linear information. It turns out that in this case we only lose very little, and we can even restrict to linear algorithms. In particular, several notions of tractability hold simultaneously for both types of available information.
Intensity interferometry: Optical imaging with kilometer baselines

description: Optical imaging with microarcsecond resolution will reveal details across and outside stellar surfaces but requires kilometer-scale interferometers, challenging to realize either on the ground or in space. Intensity interferometry, electronically connecting independent telescopes, has a noise budget that relates to the electronic time resolution, circumventing issues of atmospheric turbulence. Extents up to a few km are becoming realistic with arrays of optical air Cherenkov telescopes (primarily erected for gamma-ray studies), enabling an optical equivalent of radio interferometer arrays. Pioneered by Hanbury Brown and Twiss, digital versions of the technique have now been demonstrated, reconstructing diffraction-limited images from laboratory measurements over hundreds of optical baselines. This review outlines the method from its beginnings, describes current experiments, and sketches prospects for future observations.

description: We consider the nonlinear wave equation known as the $ϕ^{6}$ model in dimension 1+1. We describe the long time behavior of all the solutions of this model close to a sum of two kinks with energy slightly larger than twice the minimum energy of non constant stationary solutions. We prove orbital stability of two moving kinks. We show for low energy excess $ε$ that these solutions can be described for long time less o equivalent than $-\ln{(ε)}ε^{-\frac{1}{2}}$ as the sum of two moving kinks such that each kink's center is close to an explicit function which is a solution of an ordinary differential system. We give an optimal estimate in the energy norm of the remainder $(g(t),\partial_{t}g(t))$ and we prove that this estimate is achieved during a finite instant $t=T\lesssim -\ln{(ε)}ε^{-\frac{1}{2}}.$

Discriminating abilities of threshold-free evaluation metrics in link prediction

Year: 2022
Subjects: subject: Data Analysis, Statistics and Probability (physics.data-an)
subject: FOS: Physical sciences

description: Link prediction is a paradigmatic and challenging problem in network science, which attempts to uncover missing links or predict future links, based on known topology. A fundamental but still unsolved issue is how to choose proper metrics to fairly evaluate prediction algorithms. The area under the receiver operating characteristic curve (AUC) and the balanced precision (BP) are the two most popular metrics in early studies, while their effectiveness is recently under debate. At the same time, the area under the precision-recall curve (AUPR) becomes increasingly popular, especially in biological studies. Based on a toy model with tunable noise and predictability, we propose a method to measure the discriminating abilities of any given metric. We apply this method to the above three threshold-free metrics, showing that AUC and AUPR are remarkably more discriminating than BP, and AUC is slightly more discriminating than AUPR. The result suggests that it is better to simultaneously use AUC and AUPR in evaluating link prediction algorithms, at the same time, it warns us that the evaluation based only on BP may be unauthentic. This article provides a starting point towards a comprehensive picture about effectiveness of evaluation metrics for link prediction and other classification problems.

description: Excerpts from the report: The Southeast Wisconsin Rivers Basin lies in eastern and southern Wisconsin, north central Illinois, and northern Michigan. There are portions of two major continental drainage basins in the study area, the Upper Mississippi and the Great Lakes - St. Lawrence. The total drainage area is about 15,530,600 acres, or 24,266 square miles. The study area is bounded on the east by Lake Michigan, on the west by the Wisconsin and Galena-Platte drainage basins, on the south by the Wisconsin state line, except for the inclusion of the Rock River basin, downstream to Rockton, Illinois, and on the north by the northern boundary of the Menominee River basin in Michigan. The purpose of this report is to provide economic information and analysis for use in planning the orderly development of the land and water resources of the Southeast Wisconsin Rivers Basin. Although the focus is on the agricultural economy, data on other sectors of the economy are included. The report presents historic conditions and benchmark projections of the agricultural economy. As such, it sets forth directions toward which the agricultural economy is expected to move, provided no additional water resource development occurs on the existing resource base. Procedures used are briefly described, as well as the assumptions on which conclusions are based. Projections of the rural farm population, employment, income, rural farm water needs and agricultural land use to 1980, 2000, and 2020 are presented.

Subjects: subject: 420 Englisch

description: The current study investigates variation in the marking of two aspectual subcategories of the imperfective in Bahamian English. First, it looks into variable auxiliary be use in progressive and future constructions, that is, the variation between full, contracted and zero be in non-past V-ing environments and related contexts. Second, the paper examines variable application of preverbal does/is/’s in non-past habitual environments. The two variables were selected to represent the ‘informal’ and ‘anti-formal’ group respectively, that is, one feature that classifies as a reduction of English structure and one direct transfer from the creole (Allsopp, 1996, pp. lvi–lvii). Thus, in addition to examining the linguistic constraints, the study will take a close look at the stylistic factors conditioning the variation, placing a special focus on the distribution of the non-standardized variants over various registers as well as how speakers employ them to create linguistic styles.

description: In card-based cryptography, a deck of physical cards is used to achieve secure computation. A shuffle, which randomly permutes a card-sequence along with some probability distribution, ensures the security of a card-based protocol. The authors proposed a new class of shuffles called graph shuffles, which randomly permutes a card-sequence by an automorphism of a directed graph (New Generation Computing 2022). For a directed graph $G$ with $n$ vertices and $m$ edges, such a shuffle could be implemented with pile-scramble shuffles with $2(n+m)$ cards. In this paper, we study graph shuffles and give an implementation, an application, and a slight generalization of them. First, we propose a new protocol for graph shuffles with $2n+m$ cards. Second, as a new application of graph shuffles, we show that any cyclic group shuffle, which is a shuffle over a cyclic group, is a graph shuffle associated with some graph. Third, we define a hypergraph shuffle, which is a shuffle by an automorphism of a hypergraph, and show that any hypergraph shuffle can also be implemented with pile-scramble shuffles.

description: We argue that strain applied to a time-reversal and inversion breaking Weyl semi-metal in a magnetic field can induce an electric current via the chiral magnetic effect. A tight binding model is used to show that strain generically changes the locations in the Brillouin zone but also the energies of the band touching points (tips of the Weyl cones). Since axial charge in a Weyl semi-metal can relax via inter-valley scattering processes the induced current will decay with a timescale given by the lifetime of a chiral quasiparticle. We estimate the strength and lifetime of the current for typical material parameters and find that it should be experimentally observable.

Ice calibration studies for IceCube Upgrade with multi-PMT optical modules, and studies of the sensitivity of future IceCube extensions to astrophysical neutrinos in the MeV and GeV range

description: The IceCube neutrino observatory is a large-scale particle physics experiment at the South Pole. IceCube consists of a series of sensors embedded in the ice that detect the Cherenkov radiation produced when a neutrino interacts with the ice. Given its great success and reliability, the IceCube detector is being expanded through two extension projects: IceCube Upgrade and IceCube-Gen2. The IceCube Upgrade project aims to install ∼700 new optical modules in a dense configuration in the existing IceCube volume to detect low-energy neutrinos; construction is planned for the Australian summer of 2025-2026. IceCube-Gen2 envisions an expansion of the instrumented volume from 1 to 8 km3 with new optical modules. Construction is scheduled to begin shortly after the completion of IceCube Upgrade. This expansion will allow IceCube to significantly increase its detection rate of cosmic high-energy neutrinos and further improve our understandingof the universe.
 This thesis presents the results of simulation studies that evaluate the potential of future detector extensions for a number of topics. The first study focuses on the detection of low-energy neutrinos released during a core collapse supernova (CCSN) with the new IceCube-Gen2 detector when equipped with multi-PMT digital optical modules (mDOMs). It is shown that CCSNe can be detected up to distances of ∼250 kpc with a false detection rate of less than one per century. The second study examines the calibration of bubble column parameters in IceCube Upgrade. The bubble column, a region of frozen ice in the middle of the strings with poorer optical properties than the bulk ice, is a significant source of systematic uncertainties in the current detector, and determining its properties will benefit not only the future detector but also allow improved re-analyzes of existing data. This study shows that its properties can be reconstructed with high precision by lining up two adjacent mDOMs and flashing the LEDs in one of them. The last study investigates the sensitivity of IceCube Upgrade for detecting a GeV neutrino flux from a compact binary merger. The results show that the sensitivity for detecting these sources is improved by a factor of 2.4 compared to current DeepCore capabilities.
Symmetry Breaking and Convex Set Phase Diagrams for the q-state Potts Model

Year: 2016
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We demonstrate that the occurrence of symmetry breaking phase transitions together with the emergence of a local order parameter in classical statistical physics is a consequence of the geometrical structure of probability space. To this end we investigate convex sets generated by expectation values of certain observables with respect to all possible probability distributions of classical q-state spins on a two-dimensional lattice, for several values of q. The extreme points of these sets are then given by thermal Gibbs states of the classical q-state Potts model. As symmetry breaking phase transitions and the emergence of associated order parameters are signaled by the appearance ruled surfaces on these sets, this implies that symmetry breaking is ultimately a consequence of the geometrical structure of probability space. In particular we identify the different features arising for continuous and first order phase transitions and show how to obtain critical exponents and susceptibilities from the geometrical shape of the surface set. Such convex sets thus also constitute a novel and very intuitive way of constructing phase diagrams for many body systems, as all thermodynamically relevant quantities can be very naturally read off from these sets.

description: Coulomb interaction has a striking effect on electronic propagation in one dimensional conductors. The interaction of an elementary excitation with neighboring conductors favors the emergence of collective modes which eventually leads to the destruction of the Landau quasiparticle. In this process, an injected electron tends to fractionalize into separated pulses carrying a fraction of the electron charge. Here we use two-particle interferences in the electronic analog of the Hong-Ou-Mandel experiment in a quantum Hall conductor at filling factor 2 to probe the fate of a single electron emitted in the outer edge channel and interacting with the inner one. By studying both channels, we analyze the propagation of the single electron and the generation of interaction induced collective excitations in the inner channel. These complementary information reveal the fractionalization process in time domain and establish its relevance for the destruction of the quasiparticle which degrades into the collective modes.

description: In this paper we present the results of a mid infrared study of G49.5-0.4, or W51A, part of the massive starbirth complex W51. Combining public data from the $Spitzer$ IRAC camera, and Gemini mid infrared camera T-ReCS at 7.73, 9.69, 12.33 and 24.56 \micron, with spatial resolution of $\sim$0.5\arcsec, we have identified the mid infrared counterparts of 8 ultracompact HII regions, showing that two radio sources are deeply embedded in molecular clouds and another is a cloud of ionized gas. From the T-ReCS data we have unveiled the central core of W51 region, revealing massive young stellar candidates. We modeled the spectral energy distribution of the detected sources suggesting the embedded objects are sources with spectral types ranging from B3 to O5, but the majority of the fits indicate stellar objects with B1 spectral types. We also present an extinction map of IRS~2, showing that a region with lower extinction corresponds to the region where a proposed jet of gas has impacted the foreground cloud. From this map, we also derived the total extinction towards the enigmatic source IRS~2E, which amounts to $\sim$60 magnitudes in the $V$ band. We calculated the color temperature due to thermal emission of the circumstellar dust of the detected sources; the temperatures are in the interval of $\sim$100 -- 150 K, which corresponds to the emission of dust located at 0.1 pc from the central source. Finally, we show a possible mid infrared counterpart of a detected source at mm wavelengths that was found by \cite{zap08,zap09} to be a massive young stellar object undergoing a high accretion rate.

The two most favoured scenarios for this evolution are either the size growth of individual galaxies through a sequence of dry minor merger events, or the addition of larger, newly quenched galaxies to the pre-existing population (i.e., a progenitor bias effect). We use the 20k zCOSMOS-bright spectroscopic survey to select bona fide quiescent galaxies at 0.2

description: Molybdenum is a bio-essential trace nutrient, and elevated urinary molybdenum has been implicated as correlating with lower testosterone levels in men. To properly address the contention that molybdenum constitutes a potential health risk factor, we reviewed statistical research findings on molybdenum exposure and somatic levels in humans in a biological plausibility context, which is an indispensable component of reliable risk factor determination. Our analysis applied advanced nonparametric statistical modeling that expands linear regressions to include more potential variables and common confounders. The analysis shows that previously published negative molybdenum-testosterone associations no longer retain statistical relevance. In place of molybdenum as a stressor responsible for lowered testosterone levels, body mass index, age, related hormone variability, and underlying global downward trends in testosterone are shown to be the factors responsible for this effect.

description: The expansion of telecommunications incurs increasingly severe crosstalk and interference, and a physical layer cognitive method, called blind source separation (BSS), can effectively address these issues. BSS requires minimal prior knowledge to recover signals from their mixtures, agnostic to carrier frequency, signal format, and channel conditions. However, previous electronic implementations of BSS did not fulfill this versatility requirement due to the inherently narrow bandwidth of radio-frequency (RF) components, the high energy consumption of digital signal processors (DSP), and their shared weaknesses of low scalability. Here, we report a photonic BSS approach that inherits the advantages of optical devices and can fully fulfill its "blindness" aspect. Using a microring weight bank integrated on a photonic chip, we demonstrate energy-efficient, WDM-scalable BSS across 19.2 GHz of bandwidth, covering many standard frequency bands. Our system also has a high (9-bit) resolution for signal demixing thanks to a recently developed dithering control method, resulting in higher signal-to-interference ratios (SIR) even for ill-conditioned mixtures.

description: The present study was conducted across 28 sampling locations in an industrial zone (Peenya) of Bengaluru city to characterize the various chemical parameters of groundwater. Groundwater chemistry was evaluated using Water Quality Index (WQI) and Piper plots. The WQI results showed that around 78% of sampling points were unfit for drinking water consumption. Results of Piper plots categorized groundwater samples principally into Ca·Mg-HCO3 type (39%) and mixed Ca·Mg − Cl · SO4 type (53.5%). The study used principal component analysis and hierarchical cluster analysis to evaluate possible sources of water pollution. The five major principal components were extracted, and it showed that the water quality in the study area was likely influenced by both natural geogenic and anthropogenic sources. Water was not typically used for drinking purposes, but was used for various industrial uses. Human health risk assessment showed that in most sampling locations (86%), values of the Hazard Index were greater than 1, which indicated that water was not suitable for drinking because of its potential to cause non-carcinogenic health effects in adults and children. Long-term monitoring of contamination in the study area revealed that the concentration of Cr(VI) still existed at concerning levels in groundwater. Thus, the current study aids in identifying risks associated with heavy metal contamination and serves as a foundation for developing a remediation plan to address environmental issues.
Self-Sustained Recycling in the Inner Dust Ring of Pre-Transitional Disks

description: Observations of pre-transitional disks show a narrow inner dust ring and a larger outer one. They are separated by a cavity with no or only little dust. We propose an efficient recycling mechanism for the inner dust ring which keeps it in a steady-state. No major particle sources are needed for replenishment. Dust particles and pebbles drift outwards by radiation pressure and photophoresis. The pebbles grow during outward drift until they reach a balanced position where residual gravity compensates photophoresis. While still growing larger they reverse their motion and drift inwards. Eventually, their speed is fast enough that they get destroyed in collisions with other pebbles and drift outwards again. We quantify the force balance and drift velocities for the disks LkCa15 and HD135344B. We simulate single particle evolution and show that this scenario is viable. Growth and drift timescales are on the same order and a steady state can be established in the inner dust ring.

description: This paper presents a novel approach to solve simultaneously the problems of human activity recognition and whole-body motion and dynamics prediction for real-time applications. Starting from the dynamics of human motion and motor system theory, the notion of mixture of experts from deep learning has been extended to address this problem. In the proposed approach, experts are modelled as a sequence-to-sequence recurrent neural networks (RNN) architecture. Experiments show the results of 66-DoF real-world human motion prediction and action recognition during different tasks like walking and rotating.

description: The active galaxy MCG--6-30-15 has a 400 pc diameter stellar kinematically distinct core, counter-rotating with respect to the main body of the galaxy. Our previous high spatial resolution (0".1) H-band observations of this galaxy mapped the stellar kinematics and [Fe II] 1.64 μm gas dynamics though mainly restricted to the spatial region of the counter-rotating core. In this work we probe the stellar kinematics on a larger field-of-view and determine the ionised and molecular gas dynamics to study the formation of the counter-rotating core and the implications for AGN fuelling. We present integral field spectroscopy observations with SINFONI in the H and K-bands in the central 1.2 kpc and with VIMOS HR-blue in the central 4 kpc of the galaxy. Ionised gas outflows of v ~ 100 km/s are traced by the [Ca VIII] 2.32 μm coronal line and extend out to at least a radius of r ~ 140 pc. The molecular gas, traced by the H2 2.12 μm emission is also counter rotating with respect to the main body of the galaxy, indicating that the formation of the distinct core was associated with inflow of external gas into the centre of MCG--6-30-15. The molecular gas traces the available gas reservoir for AGN fuelling and is detected as close as r ~ 50 - 100 pc. External gas accretion is able to significantly replenish the fuelling reservoir suggesting that the event that formed the counter-rotating core was also the main mechanism providing gas for AGN fuelling.

description: Josephson junctions in a two-dimensional electron gas with spin-orbit coupling are a promising candidate to realize topological superconductivity. While it is known that the geometry of the junction strongly influences the size of the topological gap, the question of how to construct optimal geometries remains unexplored. We introduce a greedy numerical algorithm to optimize the shape of Majorana junctions. The core of the algorithm relies on perturbation theory and is embarrassingly parallel, which allows it to explore the design space efficiently. By introducing stochastic variations in the junction Hamiltonian, we avoid overfitting geometries to specific system parameters. Furthermore, we constrain the optimizer to produce smooth geometries by applying image filtering and fabrication resolution constraints. We run the algorithm in various setups and find that it reliably produces geometries with increased topological gaps over large parameter ranges. The results are robust to variations in the optimization starting point and the presence of disorder, which suggests the optimizer is capable of finding global maxima.

description: In this VERTICO early science paper we explore in detail how environmental mechanisms, identified in HI, affect the resolved properties of molecular gas reservoirs in cluster galaxies. The molecular gas is probed using ALMA ACA (+TP) observations of 12CO(2-1) in 51 spiral galaxies in the Virgo cluster (of which 49 are detected), all of which are included in the VIVA HI survey. The sample spans a stellar mass range of 9 < log M*/Msol < 11. We study molecular gas radial profiles, isodensity radii, and surface densities as a function of galaxy HI deficiency and morphology. There is a weak correlation between global HI and H2 deficiencies, and resolved properties of molecular gas correlate with HI deficiency: galaxies that have large HI deficiencies have relatively steep and truncated molecular gas radial profiles, which is due to the removal of low-surface density molecular gas on the outskirts. Therefore, while the environmental mechanisms observed in HI also affect molecular gas reservoirs, there is only a moderate reduction of the total amount of molecular gas.

description: Entanglement pre-thermalization (EP) is a quasi-stationary nonequilibrium state of a composite system in which each individual subsystem looks thermal but the entire system remains nonthermal due to quantum entanglement between subsystems. We theoretically study the dynamics of EP following a coherent split of a one-dimensional harmonic potential in which two interacting bosons are confined. This problem is equivalent to that of an interaction quench between two harmonic oscillators. We show that this simple model captures the bare essentials of EP; that is, each subsystem relaxes to an approximate thermal equilibrium, whereas the total system remains entangled. We find that a generalized Gibbs ensemble, which incorporates nonlocal conserved quantities, exactly describes the total system. In the presence of a symmetry-breaking perturbation, EP is quasi-stationary and eventually reaches thermal equilibrium. We analytically show that the lifetime of EP is inversely proportional to the magnitude of the perturbation.

description: Due to its robust antibacterial activity in acidic environments and effectiveness against old fluoroquinolone-resistant bacterial strains, the use of delafloxacin (DFX) is projected to increase in the coming years. Here, we investigated the effect on the thoracic limb rate (TLR) of the water flea Simocephalus vetulus under the combined exposure of DFX (0, 100, 200, and 400 µg L−1) and calcium (Ca) (26 and 78 mg L−1) using Bayesian statistics-based linear models. The findings showed unexpected increases and decreases in the TLR of maternal S. vetulus exposed to DFX in the 26 mg Ca L−1. In the 78 mg Ca L−1 condition, we found a clearer decrease in TLR during DFX treatments. In addition, in the 26 mg Ca L−1, elusive changes in the TLR of neonatal S. vetulus whose mothers were exposed to DFX were observed, whereas the reduced TLR of the neonate, whose mother was exposed to 400 µg DFX L−1, was apparent in the higher Ca condition. While the elevated Ca content did not appear to have a clear effect on organisms’ TLR, it acted as a synergist in conjunction with DFX, leading to a reduction in TLR, the underlying mechanism of which remains poorly understood. The results of our study indicate that DFX may pose an ecological risk as a xenobiotic; therefore, taking into account the abundance of Ca in specific aquatic environments, a comprehensive ecological risk assessment should be conducted. Moreover, the inclusion of Bayesian statistics in ecotoxicological studies is highly recommended to improve data analysis and interpretation.

description: A homogeneous search for stellar flares has been performed using every available Kepler light curve. An iterative light curve de-trending approach was used to filter out both astrophysical and systematic variability to detect flares. The flare recovery completeness has also been computed throughout each light curve using artificial flare injection tests, and the tools for this work have been made publicly available. The final sample contains 851,168 candidate flare events recovered above the 68% completeness threshold, which were detected from 4041 stars, or 1.9% of the stars in the Kepler database. The average flare energy detected is ~$10^{35}$ erg. The net fraction of flare stars increases with $g-i$ color, or decreasing stellar mass. For stars in this sample with previously measured rotation periods, the total relative flare luminosity is compared to the Rossby number. A tentative detection of flare activity saturation for low-mass stars with rapid rotation below a Rossby number of ~0.03 is found. A power law decay in flare activity with Rossby number is found with a slope of -1, shallower than typical measurements for X-ray activity decay with Rossby number.

Gamma-ray emission from galaxy cluster outskirts versus radio relics

description: Galaxy cluster peripheries provide important information on the nature of ICM/IGM linkage. In this paper we consider potential future observations in the gamma-ray domain at cluster edges involving the radio relic phenomenon. We focus on the spectral signature of gamma radiation that should be evident in the energy range of Fermi--LAT, i.e. $\gtrsim 10^{-1}$ GeV and the CTA energy range $\sim$ $ 10^{2}$ GeV. The spectral signature results from a comparable gamma-ray flux due to the IC and $ π^{0} $ decay on the edge of the cluster, and its spectral position is a function of the magnetic field and relative efficiency of the acceleration of protons and electrons. We aim to draw attention to the dependence of the gamma-ray structure on the magnetic field value. As an example, we carried out analyses of two types of non-thermal diffuse radio emission: the radio relic of A 2256 and the radio halo of Coma cluster. We suggest that in both cases the expected spatially correlated gamma-ray spectrum should have a characteristic structure that depends on the strength of the local magnetic field. In both of the clusters we calculated the combined flux of gamma radiation from the actual observational values of the used observables. The revealed spectral dependence on the magnetic field would allow us to relate the future spectral observations, in particular the position of the gamma-ray signature, to the value of the magnetic field in the border area between galaxy clusters and their connecting filaments, possibly constraining the estimated relative efficiency of particle acceleration at the edge of the cluster.

Design, Fabrication and Characterization of Capacitively Coupled Silicon-Organic Hybrid Modulators
Creators: name: Alam, Ahmed Shariful
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2017

description: Silicon-organic hybrid (SOH) modulators [1] offer fast and efficient electro-optic modulation with very small footprints. Traditional SOH modulators suffer from bandwidth limitation due to the higher RC time constant that originates from the resistive coupling of the RF signal. In the current thesis, we propose a new modulator concept establishing a capacitive coupling of the RF signal as opposed to the resistive one in the conventional SOH modulators and hence the name capacitively coupled SOH (CC-SOH) modulator. A high-κ dielectric, BaT iO3 is characterized in optical and in RF regime and later used to design capacitively coupled SOH modulator. The fabicated CCSOH is characterized to have a flat frequency response up to 65 GHz indicating that the 3-dB bandwidth is at least 3 times higher than the SOH modulators.
