description: Despite abundant data on the spatial distribution of contemporary human settlements, historical data on the long-term evolution of human settlements at fine spatial and temporal granularity is scarce, limiting our quantitative understanding of long-term changes of built-up areas. This is because commonly used mapping methods (e.g., image classification) and suitable data sources (i.e., aerial imagery, multi-spectral remote sensing data, LiDAR) have only been available in recent decades. However, there are alternative data sources such as cadastral records that are digitally available, containing relevant information such as building age information, allowing for an approximate, digital reconstruction of past building distributions. We conducted a non-exhaustive search of open and publicly available data resources from administrative institutions in the United States and gathered, integrated, and harmonized cadastral parcel data, tax assessment data, and building footprint data for 33 counties, wherever building footprint geometries and building construction year information was available. The result of this effort is a unique dataset which we call the Multi-Temporal Building Footprint Dataset for 33 U.S. Counties (MTBF-33). MTBF-33 contains over 6.2 million building footprints including their construction year, and can be used to derive retrospective depictions of built-up areas from 1900 to 2015, at fine spatial and temporal grain and can be used for data validation purposes, or to train statistical learning approaches aiming to extract historical information on human settlements from remote sensing data, historical maps, or similar data sources.

description: We discuss recent developments and challenges of beam dynamics in Dielectric Laser Acceleration (DLA), for both high and low energy electron beams. Starting from ultra-low emittance nanotip sources the paper follows the beam path of a tentative DLA light source concept. Acceleration in conjuction with focusing is discussed in the framework of Alternating Phase Focusing (APF) and spatial harmonic ponderomotive focusing. The paper concludes with an outlook to the beam dynamics in laser driven nanophotonic undulators, based on tilted DLA grating structures.

description: Individual inequality increases, and gender inequality exists, regarding the number of papers by computer scientists. Both patterns vanish when only papers by first authors with durable careers are considered. Underneath lies the Matthew Effect, a mechanism of cumulative advantage that amplifies differences, including gender differences. These are the results from a computational study of 300,000 female and male authors in computer science who started their careers between 1970 and 2000. The study helps identify the systemic mechanisms by which gender inequality emerges.
description: Individuelle und Geschlechter-Ungleichheit nimmt zu, was die Anzahl der Veröffentlichungen in der Informatik betrifft. Beide Muster verschwinden jedoch, wenn nur Arbeiten von Erstautor*innen mit dauerhaften Karrieren betrachtet werden.

Dies sind die Ergebnisse einer computergestützten Untersuchung von 300.000 weiblichen und männlichen Autor*innen in der Informatik, die ihre Karriere zwischen 1970 und 2000 begonnen haben. Die Studie trägt dazu bei, die systemischen Mechanismen zu ermitteln, durch die Geschlechter-Ungleichheit entsteht.

description: The exploitation of ultrafast electron dynamics in quantum cascade lasers (QCLs) holds enormous potential for intense, compact mode-locked terahertz (THz) sources, squeezed THz light, frequency mixers, and comb-based metrology systems. Yet the important sub-cycle dynamics have been notoriously difficult to access in operational THz QCLs. Here, we employ high-field THz pulses to perform the first ultrafast two-dimensional spectroscopy of a free-running THz QCL. Strong incoherent and coherent nonlinearities up to eight-wave mixing are detected below and above the laser threshold. These data not only reveal extremely short gain recovery times of 2 ps at the laser threshold, they also reflect the nonlinear polarization dynamics of the QCL laser transition for the first time, where we quantify the corresponding dephasing times between 0.9 and 1.5 ps with increasing bias currents. A density-matrix approach reproducing the emergence of all nonlinearities and their ultrafast evolution, simultaneously, allows us to map the coherently induced trajectory of the Bloch vector. The observed high-order multi-wave mixing nonlinearities benefit from resonant enhancement in the absence of absorption losses and bear potential for a number of future applications, ranging from efficient intracavity frequency conversion, mode proliferation to passive mode locking.

description: The last two decades have been characterized by diverse crises such as the financial crisis, the coronavirus pandemic and climate change. These far-reaching events and the resulting public debates repeatedly raise the question of whether and how people’s political attitudes change over time. Following on from the crises of the last two decades, this blog post takes a closer look at three questions about the changing attitudes of the population: 1. How do people view the economic situation? 2. Does it make a difference who is in the federal government? 3. Is the fear of climate change growing?

Anknüpfend an die Krisen der letzten zwei Jahrzehnte, werden in diesem Blog-Beitrag drei Fragen zum Wandel von Einstellungen der Bevölkerung näher beleuchtet: 1. Wie wird die wirtschaftliche Lage eingeschätzt? 2. Macht es einen Unterschied, wer in der Bundesregierung ist? 3. Wird die Angst vor dem Klimawandel größer?

description: We compute mixed QCD-electroweak corrections to the neutral-current Drell-Yan production of a pair of massless leptons in the high invariant mass region. Our computation is fully differential with respect to the final state particles. At relatively low values of the dilepton invariant mass, $m_{\ell \ell} \sim 200$ GeV, we find unexpectedly large mixed QCD-electroweak corrections at the level of -1%. At higher invariant masses, $m_{\ell \ell} \sim 1$ TeV, we observe that these corrections can be well approximated by the product of QCD and electroweak corrections. Hence, thanks to the well-known Sudakov enhancement of the latter, they increase at large invariant mass and reach e.g. -3% at $m_{\ell \ell} = 3$ TeV. Finally, we note that the inclusion of mixed corrections reduces the theoretical uncertainty related to the choice of electroweak input parameters to below the percent level.

A framework for scale-sensitive, spatially explicit accuracy assessment of binary built-up surface layers

description: To better understand the dynamics of human settlements, thorough knowledge of the uncertainty in geospatial built-up surface datasets is critical. While frameworks for localized accuracy assessments of categorical gridded data have been proposed to account for the spatial non-stationarity of classification accuracy, such approaches have not been applied to (binary) built-up land data. Such data differs from other data such as land cover data, due to considerable variations of built-up surface density across the rural-urban continuum resulting in switches of class imbalance, causing sparsely populated confusion matrices based on small underlying sample sizes. In this paper, we aim to fill this gap by testing common agreement measures for their suitability and plausibility to measure the localized accuracy of built-up surface data. We examine the sensitivity of localized accuracy to the assessment support, as well as to the unit of analysis, and analyze the relationships between local accuracy and density / structure-related properties of built-up areas, across rural-urban trajectories and over time. Our experiments are based on the multi-temporal Global Human Settlement Layer (GHSL) and a reference database for the state of Massachusetts (USA). We find strong variation of suitability among commonly used agreement measures, and varying levels of sensitivity to the assessment support. We then apply our framework to assess localized GHSL data accuracy over time from 1975 to 2014. Besides increasing accuracy along the rural-urban gradient, we find that accuracy generally increases over time, mainly driven by peri-urban densification processes in our study area. Moreover, we find that localized densification measures derived from the GHSL tend to overestimate peri-urban densification processes that occurred between 1975 and 2014, due to higher levels of omission errors in the GHSL epoch 1975.

description: We report the first direct measurement of the helium isotope ratio, 3He/4He, outside of the Local Interstellar Cloud, as part of science verification observations with the upgraded CRyogenic InfraRed Echelle Spectrograph (CRIRES). Our determination of 3He/4He is based on metastable HeI* absorption along the line-of-sight towards Tet02 Ori A in the Orion Nebula. We measure a value 3He/4He=(1.77+/-0.13)x10^{-4}, which is just ~40 per cent above the primordial relative abundance of these isotopes, assuming the Standard Model of particle physics and cosmology, (3He/4He)_p = (1.257+/-0.017)x10^-4. We calculate a suite of galactic chemical evolution simulations to study the Galactic build up of these isotopes, using the yields from Limongi & Chieffi (2018) for stars in the mass range M=8-100 M_sun and Lagarde (2011,2012) for M=0.8-8 M_sun. We find that these simulations simultaneously reproduce the Orion and protosolar 3He/4He values if the calculations are initialized with a primordial ratio (3He/4He)_p=(1.043+/-0.089)x10^-4. Even though the quoted error does not include the model uncertainty, this determination agrees with the Standard Model value to within ~2sigma. We also use the present-day Galactic abundance of deuterium (D/H), helium (He/H), and 3He/4He to infer an empirical limit on the primordial 3He abundance, (3He/H)_p < (1.09+/-0.18)x10^-5, which also agrees with the Standard Model value. We point out that it is becoming increasingly difficult to explain the discrepant primordial 7Li/H abundance with non-standard physics, without breaking the remarkable simultaneous agreement of three primordial element ratios (D/H, 4He/H, and 3He/4He) with the Standard Model values.

Non-perturbative Green's function method to determine the electronic spectral function due to electron-phonon interactions: Application to a graphene model from weak to strong coupling

description: In solid state physics, the electron-phonon interaction (EPI) is central to many phenomena. The theory of the renormalization of electronic properties due to EPIs became well established with the theory of Allen-Heine-Cardona, usually applied to second order in perturbation theory (P2). However, this is only valid in the weak coupling regime, while strong EPIs have been reported in many materials. Although non-perturbative (NP) methods have started to arise in the last years, they are usually not well justified, and it is not clear to what degree they reproduce the exact theory. To address this issue, we present a stochastic approach for the evaluation of the non-perturbative interacting Green's function in the adiabatic limit, and show it is equivalent to the Feynman expansion to all orders in the perturbation. Also, by defining a self-energy, we can reduce the effect of broadening needed in numerical calculations, improving convergence in the supercell size. In addition, we clarify whether it is better to average the Green's function or self-energy. Then we apply the method to a graphene tight-binding model, and obtain several interesting results: (i) The Debye-Waller term, which is normally neglected, does affect the change of the Fermi velocity. (ii) The P2 and NP self-energies differ even at room temperature for some k-points, raising the question of how well P2 works in other materials. (iii) Close to the Dirac point, positive and negative energy peaks merge. (iv) In the strong coupling regime, a peak appears at energy E=0, which is consistent with previous works on disorder and localization in graphene. (v) The spectral function becomes more asymmetric at stronger coupling and higher temperatures. Finally, in the Appendix we show that the method has better convergent properties when the coupling is strong relative to when it is weak, and discuss other technical aspects.

Quantum and classical annealing in a continuous space with multiple local minima

description: The protocol of quantum annealing is applied to an optimization problem with a one-dimensional continuous degree of freedom, a variant of the problem proposed by Shinomoto and Kabashima. The energy landscape has a number of local minima, and the classical approach of simulated annealing is predicted to have a logarithmically slow convergence to the global minimum. We show by extensive numerical analyses that quantum annealing yields a power law convergence, thus an exponential improvement over simulated annealing. The power is larger, and thus the convergence is faster, than a prediction by an existing phenomenological theory for this problem. Performance of simulated annealing is shown to be enhanced by introducing quasi-global searches across energy barriers, leading to a power-law convergence but with a smaller power than in the quantum case and thus a slower convergence classically even with quasi-global search processes. We also reveal how diabatic quantum dynamics, quantum tunneling in particular, steers the systems toward the global minimum by a meticulous choice of annealing schedule. This latter result explicitly contrasts the role of tunneling in quantum annealing against the classical counterpart of stochastic optimization by simulated annealing.

But TREs that follow international best practice can, in fact, increase, not diminish, FAIRness of data.  Adopting the internationally recognized Five Safes framework could help to better protect sensitive data while still meeting demands for a more open and accessible service delivery on the FAIR principles.

Doch TREs, die internationalen Best Practices folgen, können die FAIRness von Daten tatsächlich erhöhen und nicht verringern. Die Übernahme des international anerkannten Five-Safes-Rahmens könnte dabei helfen, sensible Daten besser zu schützen und gleichzeitig die Forderungen nach einem offeneren und zugänglicheren Dienst zu erfüllen, der den FAIR-Grundsätzen entspricht.

description: This blog series provides a step-by-step overview of the Wi4impact research project, which examines the knowledge transfer impact of science blogs and podcasts at German higher education and non-university research institutions. The first blog post presents a brief theoretical introduction to our research topic. The term knowledge transfer is by no means consistent within or outside the academic world. Broadly perceived, it denotes effects of research and science on the non-academic world. In the past, economic, and technological aspects dominated the understanding of knowledge transfer, focusing on natural sciences. Only recently there has been a paradigm shift toward a more societal significance that pays greater attention to social sciences and humanities (SSH). In the context of the umbrella term third mission, policy makers request forms of academic evaluation in all fields, which poses the question of how to measure the impact of knowledge transfer. The blog post proposes a set of definitions underlying a study of the impact of digital transfer media.
description: Diese vierteilige Blogreihe gibt einen schrittweisen Einblick in das Forschungsprojekt Wi4impact, in dem die Wissenstransferleistung von Wissenschaftsblogs und -podcasts deutscher Hochschulen und Forschungseinrichtungen untersucht wird. Im ersten Beitrag geben wir eine kurze theoretische Einführung zum Untersuchungsgegenstand. Der Begriff „Wissenstransfer“ wird innerhalb und außerhalb der akademischen Welt keineswegs einheitlich verstanden. Weit gefasst bezeichnet er die Wirkung von Forschung und Wissenschaft aus der akademischen Welt heraus. In der Vergangenheit dominierten wirtschaftliche und technologische Perspektiven das Begriffsverständnis, wobei das schwerpunktmäßige Interesse auf den Naturwissenschaften lag. Erst in jüngster Zeit zeichnet sich ein Paradigmenwechsel hin zu einer gesellschaftlichen Bedeutung ab, die den Sozial- und Geisteswissenschaften (GSW) größere Aufmerksamkeit schenkt. Unter dem Oberbegriff „Third mission“ fordert die Politik Formen der wissenschaftlichen Evaluation von allen Disziplinen ein, was die Frage aufwirft, wie die Wirkung von Wissenstransfer konkret gemessen werden kann. Der Blogbeitrag schlägt Definitionen vor, die einer Studie zum Impact von digitalen Transfermedien zugrunde liegen.

description: The Fermi Gamma-ray Burst Monitor (GBM) triggers on-board in response to $\sim$ 40 short gamma-ray bursts (SGRBs) per year; however, their large localization regions have made the search for optical counterparts a challenging endeavour. We have developed and executed an extensive program with the wide field of view of the Zwicky Transient Facility (ZTF) camera, mounted on the Palomar 48 inch Oschin telescope (P48), to perform target-of-opportunity (ToO) observations on 10 Fermi-GBM SGRBs during 2018 and 2020-2021. Bridging the large sky areas with small field of view optical telescopes in order to track the evolution of potential candidates, we look for the elusive SGRB afterglows and kilonovae (KNe) associated with these high-energy events. No counterpart has yet been found, even though more than 10 ground based telescopes, part of the Global Relay of Observatories Watching Transients Happen (GROWTH) network, have taken part in these efforts. The candidate selection procedure and the follow-up strategy have shown that ZTF is an efficient instrument for searching for poorly localized SGRBs, retrieving a reasonable number of candidates to follow-up and showing promising capabilities as the community approaches the multi-messenger era. Based on the median limiting magnitude of ZTF, our searches would have been able to retrieve a GW170817-like event up to $\sim$ 200 Mpc and SGRB afterglows to z = 0.16 or 0.4, depending on the assumed underlying energy model. Future ToOs will expand the horizon to z = 0.2 and 0.7 respectively.

description: It has been hypothesized that some form of "modular" structure in artificial neural networks should be useful for learning, compositionality, and generalization. However, defining and quantifying modularity remains an open problem. We cast the problem of detecting functional modules into the problem of detecting clusters of similar-functioning units. This begs the question of what makes two units functionally similar. For this, we consider two broad families of methods: those that define similarity based on how units respond to structured variations in inputs ("upstream"), and those based on how variations in hidden unit activations affect outputs ("downstream"). We conduct an empirical study quantifying modularity of hidden layer representations of simple feedforward, fully connected networks, across a range of hyperparameters. For each model, we quantify pairwise associations between hidden units in each layer using a variety of both upstream and downstream measures, then cluster them by maximizing their "modularity score" using established tools from network science. We find two surprising results: first, dropout dramatically increased modularity, while other forms of weight regularization had more modest effects. Second, although we observe that there is usually good agreement about clusters within both upstream methods and downstream methods, there is little agreement about the cluster assignments across these two families of methods. This has important implications for representation-learning, as it suggests that finding modular representations that reflect structure in inputs (e.g. disentanglement) may be a distinct goal from learning modular representations that reflect structure in outputs (e.g. compositionality).

description: The rise of right-wing populist parties in Europe led some mainstream political parties to attempt to regain the support of voters by adopting far-right pro-nationalist and anti-immigrant stances. However, new research out of Germany and Israel suggests this strategy primarily benefits far-right parties and not the political mainstream parties, as they had hoped. Using survey data from native-born residents in 26 European countries between 1995 and 2017 in combination with party manifesto data, the researchers found that when mainstream parties take nationalist, anti-immigration positions, they likely unintentionally boost the electoral chances of far-right party competitors.
description: Der Aufstieg rechtspopulistischer Parteien in Europa hat dazu geführt, dass einige etablierte politische Parteien versuchen, die Unterstützung der Wähler*innen zurückzugewinnen, indem sie rechtsextreme, pro-nationalistische und einwanderungsfeindliche Positionen einnehmen. Neue Forschungsergebnisse aus Deutschland und Israel deuten jedoch darauf hin, dass diese Strategie in erster Linie den rechtsextremen Parteien zugute kommt und nicht, wie erhofft, den Parteien der politischen Mitte. Anhand von Umfragedaten von Einwohner*innen mit Migrationshintergrund in 26 europäischen Ländern zwischen 1995 und 2017 in Kombination mit Daten aus Parteiprogrammen fanden die Forschenden heraus, dass Mainstream-Parteien, die nationalistische und einwanderungsfeindliche Positionen vertreten, wahrscheinlich ungewollt die Wahlchancen rechtsextremer Parteien erhöhen.

Nonlinear magnetoconductivity in Weyl and multi-Weyl semimetal in quantizing magnetic field

description: Magnetotransport and magneto-optics experiments offer a very powerful probe for studying the physical properties of materials. Here, we investigate the second-order nonlinear magnetoconductivity of tilted type-I Weyl and multi-Weyl semimetal. In contrast to the presence of chiral anomaly in the linear response regime, we show that Weyl semimetal do not host chiral charge pumping in the nonlinear transport regime. We predict that an inversion symmetry broken and tilted Weyl semimetal can support finite longitudinal nonlinear magnetoconductivity, which is otherwise absent in untilted Weyl semimetal. The nonlinear magnetoconductivity vanishes in the ultra-quantum limit, oscillates in the intermediate magnetic field regime and saturates in the semiclassical limit. The nonlinear magnetoconductivity depends intricately on the tilt orientation, and it can be used to determine the tilt orientation in Weyl and multi-Weyl semimetals, via nonlinear magnetoresistivity or second harmonic generation experiments.

description: In quasi-1D conducting nanowires spin-orbit coupling destructs spin-charge separation, intrinsic to Tomonaga-Luttinger liquid (TLL). We study renormalization of a single scattering impurity in a such liquid. Performing bosonization of low-energy excitations and exploiting perturbative renormalization analysis we extend the phase portrait in $K_s$ - $K_c$ space, obtained previously for TLL with decoupled spin-charge channels.

description: Formamide (NH$_2$CHO), a potential prebiotic precursor, has been proposed to play an important role in the context of origin of life on our planet. It has been observed in different environments in space including the protostellar regions and comets. The abundance and stability of NH$_2$CHO in the early stages of star formation can be better understood by incorporating the formation and destruction data in the astrochemical models. We carried out an experimental investigation to study the destruction of pure NH$_2$CHO ice at 12 K by the interaction of Ly$α$ (121.6 nm) photons. The UV photo destruction of NH$_2$CHO was studied using Fourier-transform infrared spectroscopy. After UV processing, the intensity of NH$_2$CHO IR bands decreases and new bands corresponding to HCN, CO, NH$_4^+$ OCN$^-$, HNCO, and CO$_2$ appeared in the spectrum. Destruction and cumulative product formation cross-sections were derived. The comparison of destruction rate derived from the cross-section in cold and dense molecular cloud for different energetic processing agents, reveals that UV photons induces an order of magnitude higher NH$_2$CHO destruction than cosmic rays, but three orders of magnitude lower than for H atoms.

description: SVR-GARCH model tends to "backward eavesdrop" when forecasting the financial time series volatility in which case it tends to simply produce the prediction by deviating the previous volatility. Though the SVR-GARCH model has achieved good performance in terms of various performance measurements, trading opportunities, peak or trough behaviors in the time series are all hampered by underestimating or overestimating the volatility. We propose a blending ARCH (BARCH) and an augmented BARCH (aBARCH) model to overcome this kind of problem and make the prediction towards better peak or trough behaviors. The method is illustrated using real data sets including SH300 and S&P500. The empirical results obtained suggest that the augmented and blending models improve the volatility forecasting ability.
