description: We study the capability of future measurements of the galaxy clustering power spectrum to probe departures from a power-law spectrum for primordial fluctuations. On considering the information from the galaxy clustering power spectrum up to quasi-linear scales, i.e. $k<0.1$ h Mpc$^{-1}$, we present forecasts for DESI, Euclid and SPHEREx in combination with CMB measurements. As examples of departures in the primordial power spectrum from a simple power-law, we consider four $Planck$ 2015 best-fits motivated by inflationary models with different breaking of the slow-roll approximation. These four representative models provide an improved fit to CMB temperature anisotropies, although not at statistical significant level. As for other extensions in the matter content of the simplest $Λ$CDM model, the complementarity of the information in the resulting matter power spectrum expected from these galaxy surveys and in the primordial power spectrum from CMB anisotropies can be effective in constraining cosmological models. We find that the three galaxy surveys can add significant information to CMB to better constrain the extra parameters of the four models considered.

description: Handlungsorientierung als Unterrichtskonzept bedeutet eine Verknüpfung von Denken und Handeln im Unterrichtsgeschehen. Die Lernenden sollen getreu dem Prinzip learning by doing bzw. learning by communicating durch aktives fremdsprachliches Handeln in möglichst authentischen Lernsituationen fremdsprachliche Handlungskompetenzen erlernen. Die Aktualität dieses Unterrichtskonzepts zeigt sich u. a. darin, dass dem Gemeinsamen europäischen Referenzrahmen (GeR) ein handlungsorientierter Ansatz zugrunde liegt. In diesem Artikel werden zunächst grundlegende Prinzipien eines handlungsorientierten Unterrichts erläutert. Darauf aufbauend wird eine mit diesem Unterrichtskonzept durchgeführte Unterrichtseinheit skizziert und auf die empirische Studie eingegangen, mithilfe derer der Unterricht ausgewertet wurde. Die Unterrichtseinheit wurde von den Chinesischlernenden so gut aufgenommen, dass die Notwendigkeit der Auseinandersetzung mit Unterrichtskonzepten für den Chinesischunterricht signifikant zum Ausdruck kommt. Die Schüler sprachen sich deutlich für einen im Sinne der Handlungsorientierung gestalteten Unterricht aus, der dazu beiträgt, die Distanz der Sprache zu überwinden und das Chinesische als authentische, lebendige und durchaus erlernbare Sprache zu erleben.

description: Populist leaders mobilize supporters to accomplish the political transformations they seek to achieve. However, once they are in office, populist leaders also encounter mobilizations against them because of their exclusionary rhetoric as well as their attack on existing democratic norms. These populists’ practices represent an erosion of (or threat to) political rights and move oppositional groups into struggle. Therefore, an increase in mobilizations under a populist leader can be seen as resistance to populism. Based on panel data analysis across 18 Latin American countries between 1990-2018, we find that populist rhetoric triggers a higher level of pro-democratic protests when it is combined with a populist leader’s rejection of democratic norms. The findings are discussed in line with the political consequences of populism in contemporary Latin America.
Higher-curvature Corrections to Holographic Entanglement with Momentum Dissipation

description: We study the effects of Gauss-Bonnet corrections on some nonlocal probes (entanglement entropy, $n$-partite information and Wilson loop) in the holographic model with momentum relaxation. Higher-curvature terms as well as scalar fields make in fact nontrivial correction to the coefficient of universal term in entanglement entropy. We use holographic methods to study such corrections. Moreover, holographic calculation indicates that mutual and tripartite information undergo a transition beyond which they identically change their values. We find that the behavior of transition curves depends on the sign of the Gauss-Bonnet coupling $λ$. The transition for $λ>0$ takes place in larger separation of subsystems than that of $λ<0$. Finally, we examine the behavior of modified part of the force between external point-like objects as a function of Gauss-Bonnet coupling and its sign.

description: David Ewins was a major figure in experimental structural dynamics. He pioneered the subject that became known as modal testing, writing the seminal book on the topic which is still in use 40 years later. He did outstanding research across a wide range of topics, notably modal testing, rotating machinery vibration and the dynamics of structural joints. He was always interested in industrial applications and was a firm believer in the need for research to demonstrate impact long before it became fashionable. He was the founding director of one of the first Rolls-Royce University Technology Centres and made major contributions to the company. He loved interacting with engineers at all levels in academia and industry, and he was a passionate educator of both PhD students and engineers in industry. His influence continues to be reflected in their careers.
$Λ_c \to Λ\ell^+ ν_\ell$ form factors and decay rates from lattice QCD with physical quark masses

description: The first lattice QCD calculation of the form factors governing $Λ_c \to Λ\ell^+ ν_\ell$ decays is reported. The calculation was performed with two different lattice spacings and includes one ensemble with a pion mass of 139(2) MeV. The resulting predictions for the $Λ_c \to Λe^+ ν_e$ and $Λ_c \to Λμ^+ ν_μ$ decay rates divided by $|V_{cs}|^2$ are $0.2007(71)(74)\:{\rm ps}^{-1}$ and $0.1945(69)(72)\:{\rm ps}^{-1}$, respectively, where the two uncertainties are statistical and systematic. Taking the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cs}|$ from a global fit and the $Λ_c$ lifetime from experiments, this translates to branching fractions of $\mathcal{B}(Λ_c\toΛe^+ν_e)=0.0380(19)_{\rm LQCD\:\:}(11)_{τ_{Λ_c}}$ and $\mathcal{B}(Λ_c\toΛμ^+ν_μ)=0.0369(19)_{\rm LQCD\:\:}(11)_{τ_{Λ_c}}$. These results are consistent with, and two times more precise than, the measurements performed recently by the BESIII Collaboration. Using instead the measured branching fractions together with the lattice calculation to determine the CKM matrix element gives $|V_{cs}|= 0.949(24)_{\rm LQCD\:\:}(14)_{τ_{Λ_c}}(49)_{\mathcal{B}}$.

description: The hidden sector U(1) vector bosons created from inflationary fluctuations can be a substantial fraction of dark matter if their mass is around $10^{-5}$eV. The creation mechanism makes the vector bosons' energy spectral density $ρ_{cdm}/ΔE$ very high. Therefore, the dark electric dipole transition rate in atoms is boosted if the energy gap between atomic states equals the mass of the vector bosons. By using the Zeeman effect, the energy gap between the 2S state and the 2P state in hydrogen atoms or hydrogen like ions can be tuned. The $2S$ state can be populated with electrons due to its relatively long life, which is about $1/7$s. When the energy gap between the semi-ground $2S$ state and the 2P state matches the mass of the cosmic vector bosons, induced transitions occur and the 2P state subsequently decays into the 1S state. The $2P\to1S$ decay emitted Lyman-$α$ photons can then be registered. The choices of target atoms depend on the experimental facilities and the mass ranges of the vector bosons. Because the mass of the vector boson is connected to the inflation scale, the proposed experiment may provide a probe to inflation.

Performance Analysis of Multi-User Massive MIMO Downlink under Channel Non-Reciprocity and Imperfect CSI

description: This paper analyzes the performance of linearly precoded time division duplex based multi-user massive MIMO downlink system under joint impacts of channel non-reciprocity (NRC) and imperfect channel state information (CSI). We consider a generic and realistic NRC model that accounts for transceiver frequency-response as well as mutual coupling mismatches at both user equipment (UE) and base station (BS) sides. The analysis covers two most prominent forms of linear precoding schemes, namely, zero-forcing (ZF) and maximum-ratio transmission (MRT), and assumes that only the statistical properties of the beamformed channel are used at the UE side to decode the received signal. Under the approximation of i.i.d. Gaussian channels, closed-form analytical expressions are derived for the effective signal to interference and noise ratios (SINRs) and the corresponding capacity lower bounds. The expressions show that, in moderate to high SNR, the additional interference caused by imperfect NRC calibration can degrade the performance of both precoders significantly. Moreover, ZF is shown to be more sensitive to NRC than MRT. Numerical evaluations with practical NRC levels indicate that this performance loss in the spectral efficiency can be as high as 42% for ZF, whereas it is typically less than 13% for MRT. It is also shown that due to the NRC, the asymptotic large-antenna performance of both precoders saturate to an identical finite level. The derived analytical expressions provide useful tools and valuable technical insight, e.g., into calculating the NRC calibration requirements in BSs and UEs for any given specific performance targets in terms of effective SINR or the system capacity bound.

description: Hyperdimensional computing is a novel paradigm, capable of processing complex data structures with simple operations. Its main limita-tions lie in the conversion of real world data onto hyperdimensional space, which due to lack of a universal translation scheme, oftentimes requires application-specific methods. This work presents a novel method for un-supervised hyperdimensional conversion of arbitrary image data. Addition-ally, this method is augmented by the ability of creating HyperSymbols, or class prototypes, provided that such class labels are available. The proposed method achieves promising performance on MNIST dataset, both in translat-ing individual samples as well as producing HyperSymbols for downstream classification task.

description: Through the continuing trend of miniaturization new cost efficient and fast methods for processing small parts are required. In this paper a new non-mechanical process for the forming process of micro deep drawing is presented. This new deep drawing process utilizes a laser initiated plasma shock wave at the target, which forms the sheet. Several pulses can be applied at one point and therefore high forming degrees can be reached without increasing the energy density. In this paper the pressure of the shock wave is measured in order to enable optimizations of the process in future. Furthermore a distribution of the thickness over the deep drawn cups will be introduced. Finally laser deep drawing of samples made out of Al99.5, Cu and stainless steel sheet metal with thicknesses of 20 µm and 50 µm are shown.

description: Peroxisomes are organelles involved in many metabolic processes including lipid metabolism, reactive oxygen species (ROS) turnover, and antimicrobial immune responses. However, the cellular mechanisms by which peroxisomes contribute to bacterial elimination in macrophages remain elusive. Here, we investigated peroxisome function in iPSC-derived human macrophages (iPSDM) during infection with Mycobacterium tuberculosis (Mtb). We discovered that Mtb-triggered peroxisome biogenesis requires the ESX-1 type 7 secretion system, critical for cytosolic access. iPSDM lacking peroxisomes were permissive to Mtb wild-type (WT) replication but were able to restrict an Mtb mutant missing functional ESX-1, suggesting a role for peroxisomes in the control of cytosolic but not phagosomal Mtb. Using genetically encoded localization-dependent ROS probes, we found peroxisomes increased ROS levels during Mtb WT infection. Thus, human macrophages respond to the infection by increasing peroxisomes that generate ROS primarily to restrict cytosolic Mtb. Our data uncover a peroxisome-controlled, ROS-mediated mechanism that contributes to the restriction of cytosolic bacteria.

description: Food safety is important to prevent foodborne illnesses that can negatively affect public health and the economy. Preventative measures can be taken by government agencies, food-related workers, and consumers to reduce the occurrence of such illnesses. This paper examines the impact of government policies on food safety from the perspective of consumers, restaurant employees and employers, and food processing workers. The first essay explores how food safety recalls affect consumer behavior. The second essay studies the impact of minimum wage policies on service quality in the restaurant industry. The third essay investigates the effect of minimum wage policies on product food safety in the meat and poultry processing industry.
Resummation of Transverse Momentum Distributions in Distribution Space

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Differential spectra in observables that resolve additional soft or collinear QCD emissions exhibit Sudakov double logarithms in the form of logarithmic plus distributions. Important examples are the total transverse momentum $q_T$ in color-singlet production, N-jettiness (with thrust or beam thrust as special cases), but also jet mass and more complicated jet substructure observables. The all-order logarithmic structure of such distributions is often fully encoded in differential equations, so-called (renormalization group) evolution equations. We introduce a well-defined technique of distributional scale setting, which allows one to treat logarithmic plus distributions like ordinary logarithms when solving these differential equations. In particular, this allows one (through canonical scale choices) to minimize logarithmic contributions in the boundary terms of the solution, and to obtain the full distributional logarithmic structure from the solution's evolution kernel directly in distribution space. We apply this technique to the $q_T$ distribution, where the two-dimensional nature of convolutions leads to additional difficulties (compared to one-dimensional cases like thrust), and for which the resummation in distribution (or momentum) space has been a long-standing open question. For the first time, we show how to perform the RG evolution fully in momentum space, thereby directly resumming the logarithms $[\ln^n(q_T^2/Q^2)/q_T^2]_+$ appearing in the physical $q_T$ distribution. The resummation accuracy is then solely determined by the perturbative expansion of the associated anomalous dimensions.

description: This report aims to provide insights into how recent PNG government reform efforts are impacting on the primary health care system. These include the introduction of a free primary health care policy, national grants to provinces for recurrent health expenditure, changes in medical supply policies, and development funds allocated to members of parliament for health infrastructure in their electorates. It presents illustrations of how PNG’s primary health care system functions, drawing mainly on the perspectives of health administrators and frontline workers on the ground. The findings detailed in this report set out the realities of providing frontline health services to communities at the local level. This provides some insights into health system operations and reveals how different provincial contexts influence the implementation of health reforms, the utilisation of available health funds and the performance of health facilities.

description: Die Erkrankung an Mundhöhlenkarzinomen bedeutet für betroffene Patienten häufig massive Funktionsverluste und Veränderungen ihrer bisherigen Lebensweise.Funktionsstörungen und Auffälligkeiten ergeben sich bei den Abläufen der Nahrungsaufnahme, des Sprechens und beim äußeren Erscheinungsbild. Als zusätzliche Belastung für den Patienten tritt die Grunderkrankung Krebs hinzu. Die vorliegende Untersuchung verfolgte das Ziel, Belastungsfaktoren und deren Bedeutung, die sich aus dieser Erkrankung für die Betroffenen ergeben, zu erheben. Um die subjektiven Bedeutungsstrukturen hervorzuheben, wurde als Erhebungsinstrument das narrative Interview eingesetzt. Insgesamt wurden 14 Interviews mit 6 Frauen und 8 Männern geführt. Die Auswertung erfolgte nach inhaltsanalytischen Kriterien. Als Ergebnis kann festgehalten werden, dass es sich bei der Erkrankung an Mundhöhlenkarzinomen um ein lebensveränderndes Ereignis handeln kann.Die Verarbeitung dieses Ereignisses kann somit auch als längerfristiger Prozess betrachtet werden. Als Auswirkung der Funktionsverluste begleiten insbesondere Ängste, Unsicherheiten, Scham und Trauer die Patienten. Vermeidungsverhalten und Isolierungstendenzen treten als häufige Konsequenz auf die erlittene Schädigung auf. Starke Beziehungsgeflechte einerseits, aber auch aktives Verhalten und Selbstbewusstsein scheinen die Verarbeitung günstig zu beeinflussen. Auf Grund der Bedeutungsstärke der psychosozialen Faktoren bei schwerwiegenden Erkrankung bzw. chronischen Defektzuständen, ergibt sich somit für therapeutische Handlungskonsequenzen eine stärkere Berücksichtigung dieser Faktoren. Die Berücksichtigung der Individualität einer jeden Krankengeschichte sollte hierbei als zusätzliches Kriterium wesentlich sein.

description: Through a combination of laser beams, we engineer a two-dimensional optical lattice of Mexican hat potentials able to host atoms in its ring-shaped wells. When tunneling can be ignored (at high laser intensities), we show that a well-defined qubit can be associated with the states of the atoms trapped in each of the rings. Each of these two-level systems can be manipulated by a suitable configuration of Raman laser beams imprinting a synthetic flux onto each Mexican hat cell of the lattice. Overall, we believe that the system has the potential to form a scalable architecture for atomtronic flux qubits.

description: After researching the digital news preservation landscape in the USA, Portico identified a potential gap. While libraries and archives have strategies for preserving print newspapers, hyper-local digital newspapers are less likely to be preserved. This is at a time of rapid loss of hyper-local print news and an increased dependence on digital-only news.

A mechanism for preserving digital news is web archiving, but due to the rapid turnover of stories on news websites, it can be difficult to visit the site frequently enough to capture every article. Some newspapers provide RSS feeds, but not all, and it can be difficult to detect corrected articles in these feeds. Other newspapers implement a subscription model and cannot be harvested without a special arrangement. Some newspapers are aggregated into larger databases, but these often don’t include the smallest digital-only platforms and are for-profit subscription services that may not be preserved by a third party.

Portico is a community-supported dark archive for scholarly material that forms agreements and works with publishers to preserve their content. Based on this research, Portico initiated a pilot to determine if digital news articles could be managed in a similar way to journal articles. Portico partnered with a single newspaper and worked with their content management system provider to retrieve an XML export of every article. The XML and supporting files (photos etc.) were successfully ingested into the archive and were similar to journal articles. To confirm if this was repeatable, Portico worked with another newspaper on the same platform and reused the workflow with few changes.

Portico is repeating this experiment with two more newspapers on different platforms. If the content can be archived from each, Portico will seek to expand the work and develop a business model to support a broader effort in digital news preservation. An early step will be to reach out to the ~3000 newspapers on the platforms that have already been configured.

For the poster, the author will share details of the process used for this project and seek feedback from the community about the value of this approach for preserving digital news.

description: Graphene quantum dots (GQD's) have optical properties which are very different from those of an extended graphene sheet. In this Article we explore how the size, shape and edge--structure of a GQD affect its optical conductivity. Using representation theory, we derive optical selection rules for regular-shaped dots, starting from the symmetry properties of the current operator. We find that, where the x- and y-components of the current operator transform with the same irreducible representation (irrep) of the point group - for example in triangular or hexagonal GQD's - the optical conductivity is independent of the polarisation of the light. On the other hand, where these components transform with different irreps - for example in rectangular GQD's - the optical conductivity depends on the polarisation of light. We find that GQD's with non-commuting point-group operations - for example dots of rectangular shape - can be distinguished from GQD's with commuting point-group operations - for example dots of triangular or hexagonal shape - by using polarized light. We carry out explicit calculations of the optical conductivity of GQD's described by a simple tight--binding model and, for dots of intermediate size, \textcolor{blue}{($10 \lesssim L \lesssim 50\ \text{nm}$)} find an absorption peak in the low--frequency range of the spectrum which allows us to distinguish between dots with zigzag and armchair edges. We also clarify the one-dimensional nature of states at the van Hove singularity in graphene, providing a possible explanation for very high exciton-binding energies. Finally we discuss the role of atomic vacancies and shape asymmetry.

description: A touring exhibition with objects from the Egyptian collection of the Rijksmuseum van Oudheden (RMO) in Leiden was ready to be transported to Japan, when international travel was curtailed in March 2020 due to the Covid-19 pandemic. After a delay of five months, it was possible to mount the show at the first venue, but without couriers from the RMO. A plan was devised to enable the Japanese team to unpack and install the objects while a team from the RMO followed the process through a livestreaming video connection that allowed mutual communication in real-time. This contribution summarises how the exhibition’s partners prepared for this unusual installation method by adapting to, until then, unprecedented circumstances and reflects on its merits and disadvantages.

description: We calculate the energy and angular momentum fluxes across the event horizon of a tidally deformed, rapidly rotating black hole to next-to-leading order in the curvature of the external spacetime. These are expressed in terms of tidal quadrupole moments and their time derivatives, which provide a characterization of a generic tidal environment. As an application of our results, we provide an expression for the energy and angular-momentum fluxes across the horizon when the black hole is a member of a binary system on a slowly-moving, quasi-circular orbit. Our expressions are accurate to 1.5 post-Newtonian order beyond the leading-order fluxes, but they are valid for arbitrary mass ratios. We compare our results to those previously obtained in the case of an extreme mass ratio binary, and find that they do not agree at the 1.5 post-Newtonian order. We investigate a number of possible sources for this discrepancy, but are ultimately unable to resolve it.

description: In der vorliegenden Arbeit werden inhomogene Ladungs- und Spinverteilungen, sog. Streifenstrukturen, als Grundzustandseigenschaften von dotieterten Einband-Hubbard-Modellen untersucht. Experimentell wurden Streifenstrukturen in dotierten Kuprat- Supraleitern nachgewiesen. Das Hubbard-Modell wird anhand von Gutzwiller-Wellenfunktionen untersucht. Der ursprügliche Gutzwiller-Ansatz wurde dabei um zwei äußere Variationsfelder erweitert, welche die Ausprägung von Ladungs- und Spininhomgenitäten bewerkstelligen. Um methodische Probleme in 2D-Rechnungen zu umgehen, führen wir unsere Berechnungen in einer Dimension unter Verwendung von Superzellen durch. Systeme mit ausschließlich Nächstem-Nachbar-Hopping zeigen bei Dotierungen 0
description: In the present work we study inhomogenous charge and spin distributions, so called stripes, as groundstate properties of doped one band Hubbard models. There is experimental evidence for stripes in doped cuprate-superconductors. Thereby, the Hubbard model is investigated by using Gutzwiller-type wave functions. In order to allow for inhomogenous charge and spin distributions, the original Gutzwiller Ansatz has been extended by two atomic fields per sites which are treated as further variational parameters. To avoid numerical problems as seen in two dimensional supercell calculations, we have performed calculations with one dimensional supercells. Systems with only nearest neighbour hopping show stripes with a characteristic periodicity n=1/d for a given doping level 0

description: Biomass feedstocks can be used to substitute fossil fuels and effectively remove carbon from the atmosphere to offset residual CO2 emissions from fossil fuel combustion and other sectors. Both features make biomass valuable for climate change mitigation; therefore, CO2 emission mitigation leads to complex and dynamic interactions between the energy and the land-use sector via emission pricing policies and bioenergy markets. Projected bioenergy deployment depends on climate target stringency as well as assumptions about context variables such as technology development, energy and land markets as well as policies. This study investigates the intra- and intersectorial effects on physical quantities and prices by coupling models of the energy (REMIND) and land-use sector (MAgPIE) using an iterative soft-link approach. The model framework is used to investigate variations of a broad set of context variables, including the harmonized variations on bioenergy technologies of the 33rd model comparison study of the Stanford Energy Modeling Forum (EMF-33) on climate change mitigation and large scale bioenergy deployment. Results indicate that CO2 emission mitigation triggers strong decline of fossil fuel use and rapid growth of bioenergy deployment around midcentury (~ 150 EJ/year) reaching saturation towards end-of-century. Varying context variables leads to diverse changes on mid-century bioenergy markets and carbon pricing. For example, reducing the ability to exploit the carbon value of bioenergy increases bioenergy use to substitute fossil fuels, whereas limitations on bioenergy supply shift bioenergy use to conversion alternatives featuring higher carbon capture rates. Radical variations, like fully excluding all technologies that combine bioenergy use with carbon removal, lead to substantial intersectorial effects by increasing bioenergy demand and increased economic pressure on both sectors. More gradual variations like selective exclusion of advanced bioliquid technologies in the energy sector or changes in diets mostly lead to substantial intrasectorial reallocation effects. The results deepen our understanding of the land-energy nexus, and we discuss the importance of carefully choosing variations in sensitivity analyses to provide a balanced assessment.
