description: Microwave driving is a ubiquitous technique for superconducting qubits (SCQs), but the dressed states description based on the conventionally used perturbation theory cannot fully capture the dynamics in the strong driving limit. Comprehensive studies beyond these approximations applicable to transmon-based circuit quantum electrodynamics (QED) systems are unfortunately rare as the relevant works have been mainly limited to single-mode or two-state systems. In this work, we investigate a microwave-dressed transmon coupled to a single quantized mode over a wide range of driving parameters. We reveal that the interaction between the transmon and resonator as well as the properties of each mode is significantly renormalized in the strong driving limit. Unlike previous theoretical works, we establish a non-recursive, and non-Floquet theory beyond the perturbative regimes, which excellently quantifies the experiments. This work expands our fundamental understanding of dressed cavity QED-like systems beyond the conventional approximations. Our work will also contribute to fast quantum gate implementation, qubit parameter engineering, and fundamental studies on driven nonlinear systems.

description: We assess the potential of the ferrimagnetic spinel ferrites CoFe2O4 and NiFe2O4 to act as spin filtering barriers in magnetic tunnel junctions. Our study is based on the electronic structure calculated by means of first-principles density functional theory within different approximations for the exchange correlation energy. We show that, in agreement with previous calculations, the densities of states suggest a lower tunneling barrier for minority spin electrons, and thus a negative spin-filter effect. However, a more detailed analysis based on the complex band-structure reveals that both signs for the spin-filtering efficiency are possible, depending on the band alignment between the electrode and the barrier materials and depending on the specific wave-function symmetry of the relevant bands within the electrode.

description: This paper proposes the use of an event camera as a component of a vision system that enables counting of fast-moving objects - in this case, falling corn grains. These type of cameras transmit information about the change in brightness of individual pixels and are characterised by low latency, no motion blur, correct operation in different lighting conditions, as well as very low power consumption. The proposed counting algorithm processes events in real time. The operation of the solution was demonstrated on a stand consisting of a chute with a vibrating feeder, which allowed the number of grains falling to be adjusted. The objective of the control system with a PID controller was to maintain a constant average number of falling objects. The proposed solution was subjected to a series of tests to determine the correctness of the developed method operation. On their basis, the validity of using an event camera to count small, fast-moving objects and the associated wide range of potential industrial applications can be confirmed.

title: Measurement of the Neutron-Neutron Scattering Length
Creators: name: Knösel, Marco
Publisher: name: UNSPECIFIED
Year: 2023

description: The ¹S₀ neutron-neutron scattering length aₙₙ characterizes the two-neutron interaction at low energies and therefore is a fundamental quantity in many broad research fields such as nuclear structure physics. There were numerous attempts to determine the scattering length in the past decades, some of them with contradicting results, also including more recent ones. The precise and accurate measurement of aₙₙ still remains challenging and to this day, in contrast to the proton-proton scattering length, no direct measurement via n-n scattering is feasible. In this work, a new approach to measure aₙₙ is presented that makes use of relativistic radioactive ion beams created at high energies, in order to investigate n-n scattering at low energies. The experiment will be conducted at the "Radioactive Ion Beam Factory" of the research institute RIKEN in Japan and aims at the investigation of the free two-neutron system using the knockout reactions ⁶He(p,pα)2n and t(p,2p)2n. Furthermore, single-neutron events resulting from the d(p,2p)n reaction will serve for calibration and validation purposes. In the case of the ⁶He(p,pα)2n reaction, the n-n scattering length is accessible by comparison of the experimentally determined two-neutron relative-energy spectrum to calculations using the effective field theory for halo nuclei, called "Halo EFT". For the t(p,2p)2n reaction, the corresponding calculations will instead be based on pionless EFT. For the purpose of this experiment, the new high-resolution neutron detector HIME is currently developed and constructed at the "Institut für Kernphysik" in Darmstadt, Germany. A prototype of that detector has already been built at RIKEN. In this work, it was taken in operation and tested with electronics from "Gesellschaft für Schwerionenforschung" in Darmstadt. All reactions will take place in inverse kinematics with a beam energy of about 200 MeV/nucleon, resulting in two-neutron systems that move with relativistic velocity in the laboratory system. Thereby, a nearly constant neutron-detection efficiency in the relative-energy region of interest can be achieved. The measurements will be kinematically complete, which allows for a strong background suppression. In order to reach sufficient resolution, the relative-energy spectrum will be reconstructed by direct invariant-mass measurement, requiring coincident two-neutron detection. The analysis methods for the reconstruction of the primary interaction points in the neutron detector, which have been developed in this work, are tested and discussed with simulated data. Due to the limited resolution, efficiency and acceptance of the experimental setup, the measured relative-energy distribution cannot be compared directly to theoretical calculations. Different approaches of solving this issue are presented and discussed with simulated data as well.

description: We investigate with angle resolved photoelectron spectroscopy the change of the Fermi Surface (FS) and the main bands from the paramagnetic (PM) state to the antiferromagnetic (AFM) occurring below 72 K in Fe_{1.06}Te. The evolution is completely different from that observed in iron-pnictides as nesting is absent. The AFM state is a rather good metal, in agreement with our magnetic band structure calculation. On the other hand, the PM state is very anomalous with a large pseudogap on the electron pocket that closes in the AFM state. We discuss this behavior in connection with spin fluctuations existing above the magnetic transition and the correlations predicted in the spin-freezing regime of the incoherent metallic state.

description: To better understand DNA's 3D folding in cell nuclei, researchers developed chromosome capture methods such as Hi-C that measure the contact frequencies between all DNA segment pairs across the genome. As Hi-C data sets often are massive, it is common to use bioinformatics methods to group DNA segments into 3D regions with correlated contact patterns, such as Topologically Associated Domains (TADs) and A/B compartments. Recently, another research direction emerged that treats the Hi-C data as a network of 3D contacts. In this representation, one can use community detection algorithms from complex network theory that group nodes into tightly connected mesoscale communities. However, because Hi-C networks are so densely connected, several node partitions may represent feasible solutions to the community detection problem but are indistinguishable unless including other data. Because this limitation is a fundamental property of the network, this problem persists regardless of the community-finding or data-clustering method. To help remedy this problem, we developed a method that charts the solution landscape of network partitions in Hi-C data from human cells. Our approach allows us to scan seamlessly through the scales of the network and determine regimes where we can expect reliable community structures. We find that some scales are more robust than others and that strong clusters may differ significantly. Our work highlights that finding a robust community structure hinges on thoughtful algorithm design or method cross-evaluation.

description: Preservice teacher training programs for linguistically and culturally responsive Physical Education Teacher Education (PETE) are still in the early stages of development. No evidence is known, so far. The study examined the effects of an intervention within the context of a PETE program on attitudes towards linguistically responsive teaching (LCD). The study used a quasi-experiment with two intervention groups (IG1 and IG2) and one control group (CG). Thirdy-six students were included (age: 22.55 ± 3.96 years), with 10 assigned for the IG1, 15 assigned for the IG2 and 11 for the CG. IG1 and IG2 participated in a  excursions (duration: 15 lessons 90 min each) based on attitudes changing strategies. All groups were pre-and post-tested in attitudes towards LCD. The control group did not receive any treatment. After the intervention, significant improvements were found in the IG1 and IG2 on several attitudes towards LCD (Pillai F(22,42) = 2.76, p = .002, η2p = 0.59) using repeated-measures multivariate analysis of variance. This study provides the first evidence from a quasi-experiment on increasing an important PETE aspect related to LCD. The program may be improved and further analyzed to install a method to achieve one important educational goal within ordinary PETE programs in Germany and to contribute to the professional development of the preservice teachers in planning, executing and evaluating their lessons regarding LCD.

description: We analyze in full mathematical rigor the most general quartically perturbed invariant probability measure for a random tensor. Using a version of the Loop Vertex Expansion (which we call the mixed expansion) we show that the cumulants write as explicit series in 1/N plus bounded rest terms. The mixed expansion recasts the problem of determining the subleading corrections in 1/N into a simple combinatorial problem of counting trees decorated by a finite number of loop edges. As an aside, we use the mixed expansion to show that the (divergent) perturbative expansion of the tensor models is Borel summable and to prove that the cumulants respect an uniform scaling bound. In particular the quartically perturbed measures fall, in the N to infinity limit, in the universality class of Gaussian tensor models.

description: Specific signalling thresholds of the WNT/β-catenin pathway affect embryogenesis and tissue homeostasis in the adult, with mutations in this pathway frequently occurring in cancer. Excessive WNT/β-catenin activity inhibits murine anterior development associated with embryonic lethality and accounts for the driver event in 80% of human colorectal cancers. Uncontrolled WNT/β-catenin signalling arises primarily from impairment mutation in the tumour suppressor gene APC that otherwise prevents prolonged stabilisation of β-catenin. Surprisingly, no inhibitor compounds for WNT/β-catenin signalling have reached clinical use in part owing to the lack of specific in vivo assays that discriminate between on-target activities and dose-limiting toxicities. Here, we present a simple in vivo assay with a binary outcome whereby the administration of candidate compounds to pregnant and phenotypically normal Apcflox/flox mice can rescue in utero death of Apcmin/flox mutant conceptus without subsequent post-mortem assessment of WNT/β-catenin signalling. Indeed, the phenotypic plasticity of born Apcmin/flox conceptus enables future refinement of our assay to potentially enable dosage finding and cross-compound comparisons. Thus, we show for the first time the suitability of endogenous WNT/β-catenin signalling during embryonic development to provide an unambiguous and sensitive mammalian in vivo model to assess the efficacy and bioavailability of potential WNT/β-catenin antagonists.

description: Physical Education (PE) has a great potential to address education for sustainable development (ESD) as an overarching topic. But up to now this educational potential has not yet been fully utilized. The development of teaching competencies as well as global competencies of students has been called for by the German Ministry of Education and the Arts across all school subjects. However, generally speaking, PE teachers do not associate their subject with ESD. This might be due to the lack of knowledge about the concept of ESD, or to the separate teaching of contents within PE teacher education. This means that content knowledge, pedagogical content knowledge and pedagogical knowledge are taught neither in relation to each other nor to teaching practice within teacher education.

In this article we present a modular concept for a university class that implements ESD in PE teacher education: ESD outdoor – Education for sustainable development through outdoor sports. A theoretical seminar with contents like the educational concept of ESD and specific sustainability topics was implemented parallel to a practical sport climbing course. Students were stimulated to link theoretical and practical contents during a field trip, to reflect on their routines in sport with regard to sustainable development, that is environmental integrity, social equity, and long-term economic vitality. Based on this, students were guided to develop and to try action alternatives. Additionally students prepared and implemented teaching units for specific topics and analyzed them from an educational perspective.

description: In this work, we propose a parameter estimation framework for fracture propagation problems. The fracture problem is described by a phase-field method. Parameter estimation is realized with a Bayesian approach. Here, the focus is on uncertainties arising in the solid material parameters and the critical energy release rate. A reference value (obtained on a sufficiently refined mesh) as the replacement of measurement data will be chosen, and their posterior distribution is obtained. Due to time- and mesh dependencies of the problem, the computational costs can be high. Using Bayesian inversion, we solve the problem on a relatively coarse mesh and fit the parameters. In several numerical examples our proposed framework is substantiated and the obtained load-displacement curves, that are usually the target functions, are matched with the reference values. © 2020, The Author(s).

description: We present a Quality by Design (QbD) styled approach for optimizing lipid nanoparticle (LNP) formulations, aiming to offer scientists an accessible workflow. The inherent restriction in these studies, where the molar ratios of ionizable, helper, and PEG lipids must add up to 100%, requires specialized design and analysis methods to accommodate this mixture constraint. Focusing on lipid and process factors that are commonly used in LNP design optimization, we provide steps that avoid many of the difficulties that traditionally arise in the design and analysis of mixture-process experiments by employing space-filling designs and utilizing the recently developed statistical framework of self-validated ensemble models (SVEM). In addition to producing candidate optimal formulations, the workflow also builds graphical summaries of the fitted statistical models that simplify the interpretation of the results. The newly identified candidate formulations are assessed with confirmation runs and optionally can be conducted in the context of a more comprehensive second-phase study.

description: Solar spectral irradiance measured by two recently developed array spectroradiometers (called UV-BTS and VIS-BTS) are compared to the results of a scanning double monochromator system which is certified as a travelling reference instrument by the Network for the detection of atmospheric composition change (NDACC) and fulfils the specifications of S-2 UV instruments of the world meteorological organization (WMO). The comparison took place between 15 and 18 May 2017 at the Institute of Meteorology and Climatology of the University of Hanover (IMuK) between 4:00 and 17:00UTC. The UV-BTS array spectroradiometer is equipped with special hardware to significantly reduce internal stray light which has been the limiting factor of many array spectroradiometers in the past. It covers a wavelength range of 200 nm-430 nm. The VIS-BTS covers a wider spectral range from 280 nm up to 1050 nm, and stray light reduction is achieved by mathematical methods. For the evaluation, wavelength integrated quantities and spectral global irradiance are compared. The deviation for UV index measured by the UV-BTS, is within ±1% for solar zenith angles (SZA) below 70° and increased to a maximum of ±3% for SZA between 70° and 85° when synchronisation between measurements was possible. The deviation of global spectral irradiance is smaller ±2.5% in the spectral range from 300 nm to 420 nm (evaluated for SZA < 70°). The VIS-BTS achieved the same deviation for blue light hazard as the UV-BTS for the UV index. The evaluations of global spectral irradiance data of the VIS-BTS show a deviation smaller than ±2% in the spectral range from 365 nm to 900 nm (evaluated for SZA < 70°). Below 365 nm, the deviation rises up to ±7% at 305 nm due to remaining stray light. The agreement within the limited time of the intercomparison is considered to be satisfactory for a number of applications and provides a good basis for further investigations. © 2018 IOP Publishing Ltd.

description: Entropy-based (M_N) moment closures for kinetic equations are defined by a constrained optimization problem that must be solved at every point in a space-time mesh, making it important to solve these optimization problems accurately and efficiently. We present a complete and practical numerical algorithm for solving the dual problem in one-dimensional, slab geometries. The closure is only well-defined on the set of moments that are realizable from a positive underlying distribution, and as the boundary of the realizable set is approached, the dual problem becomes increasingly difficult to solve due to ill-conditioning of the Hessian matrix. To improve the condition number of the Hessian, we advocate the use of a change of polynomial basis, defined using a Cholesky factorization of the Hessian, that permits solution of problems nearer to the boundary of the realizable set. We also advocate a fixed quadrature scheme, rather than adaptive quadrature, since the latter introduces unnecessary expense and changes the computationally realizable set as the quadrature changes. For very ill-conditioned problems, we use regularization to make the optimization algorithm robust. We design a manufactured solution and demonstrate that the adaptive-basis optimization algorithm reduces the need for regularization. This is important since we also show that regularization slows, and even stalls, convergence of the numerical simulation when refining the space-time mesh. We also simulate two well-known benchmark problems. There we find that our adaptive-basis, fixed-quadrature algorithm uses less regularization than alternatives, although differences in the resulting numerical simulations are more sensitive to the regularization strategy than to the choice of basis.

description: The Hubble constant inferred from the 6-parameter fit to the CMB power spectrum conflicts with the value obtained from direct measurements via type Ia supernova and Cepheids observations. We write down effective operators involving spin-0, spin-1/2, and spin-1 dark matter that lead to the relativistic production of dark matter particles at early times, and consequently lead to an increase in the number of relativistic degrees of freedom. This mechanism which is amenable to CMB, BBN, and structure formation observables can sufficiently raise the value of the Hubble constant derived from CMB and reconcile local and CMB probes of the Hubble constant. This mechanism alone increases $H_0$ up to $70\, {\rm km s^{-1} Mpc^{-1}}$, and with the help of a Phantom-like cosmology, reach $H_0 \simeq 71-73\, {\rm km s^{-1} Mpc^{-1}}$. Lastly, we outline the region of parameter space which reproduces $H_0 \simeq 71-73\, {\rm km s^{-1} Mpc^{-1}}$ while obeying all relevant constraints.

description: Climate change can only be tackled with public support for sustainable policies. Thus, public attitudes towards climate change matter. More than 3 decades of climate change opinion (CCO) research—conducted by geographers, environmental psychologists, behavioural scientists, sociologists etc.—have provided us with a wealth of information about which predictors shape public CCOs. This review synthesises these findings and highlights the different geographies (the self, the nation, the region, the digital) that emerge within this research. Given the increased importance of social media, virtual geographies of climate change scepticism are increasingly being identified. Our paper argues that new research agendas must be developed to address the meshwork of virtual space and small scale geographies (regions, towns, districts) in which CCOs are formed. © 2022 The Authors.

description: We consider the problem of minimizing an objective function that depends on an orthonormal matrix. This situation is encountered when looking for common principal components, for example, and the Flury method is a popular approach. However, the Flury method is not effective for higher dimensional problems. We obtain several simple majorization-minizmation (MM) algorithms that provide solutions to this problem and are effective in higher dimensions. We then use simulated data to compare them with other approaches in terms of convergence and computational time.

description: The performance of inertial navigation systems is largely dependent on the stable flow of external measurements and information to guarantee continuous filter updates and bind the inertial solution drift. Platforms in different operational environments may be prevented at some point from receiving external measurements, thus exposing their navigation solution to drift. Over the years, a wide variety of works have been proposed to overcome this shortcoming, by exploiting knowledge of the system current conditions and turning it into an applicable source of information to update the navigation filter. This paper aims to provide an extensive survey of information aided navigation, broadly classified into direct, indirect, and model aiding. Each approach is described by the notable works that implemented its concept, use cases, relevant state updates, and their corresponding measurement models. By matching the appropriate constraint to a given scenario, one will be able to improve the navigation solution accuracy, compensate for the lost information, and uncover certain internal states, that would otherwise remain unobservable.

description: Artificial Intelligence (AI) is at the forefront of modern technology, and its effects are felt in many areas of society. To prevent algorithmic disparities, fairness, accountability, transparency, and ethics (FATE) in AI are being implemented. However, the current discourse on these issues is largely dominated by more economically developed countries (MEDC), leaving out local knowledge, cultural pluralism, and global fairness. This study aims to address this gap by examining FATE-related desiderata, particularly transparency and ethics, in areas of the global South that are underserved by AI. A user study (n=43) and a participatory session (n=30) were conducted to achieve this goal. The results showed that AI models can encode bias and amplify stereotypes. To promote inclusivity, a community-led strategy is proposed to collect and curate representative data for responsible AI design. This will enable the affected community or individuals to monitor the increasing use of AI-powered systems. Additionally, recommendations based on public input are provided to ensure that AI adheres to social values and context-specific FATE needs.

description: We present the first-ever collection of delta Scuti stars found over the entire area of the Small Magellanic Cloud (SMC). The sample consists of 2810 variables of which over 2600 objects belong to the SMC while the remaining stars are most likely members of the Milky Way's halo. The sample has been divided into 2733 singlemode and 77 multimode pulsators. We provide observational parameters (pulsation periods, mean magnitudes, amplitudes, Fourier coefficients) of all delta Sct stars and the long-term I- and V-band time-series photometric measurements collected during the fourth phase of the Optical Gravitational Lensing Experiment (OGLE-IV).

description: In this paper, we propose a real-time FPGA implementation of the Semi-Global Matching (SGM) stereo vision algorithm. The designed module supports a 4K/Ultra HD (3840 x 2160 pixels @ 30 frames per second) video stream in a 4 pixel per clock (ppc) format and a 64-pixel disparity range. The baseline SGM implementation had to be modified to process pixels in the 4ppc format and meet the timing constrains, however, our version provides results comparable to the original design. The solution has been positively evaluated on the Xilinx VC707 development board with a Virtex-7 FPGA device.

description: The matching of the soundtrack in a movie or a video can have an enormous influence in the message being conveyed and its impact, in the sense of involvement and engagement, and ultimately in their aesthetic and entertainment qualities. Art is often associated with creativity, implying the presence of inspiration, originality and appropriateness. Evolutionary systems provides us with the novelty, showing us new and subtly different solutions in every generation, possibly stimulating the creativity of the human using the system. In this paper, we present Genetic Soundtracks, an evolutionary approach to the creative matching of audio to a video. It analyzes both media to extract features based on their content, and adopts genetic algorithms, with the purpose of truncating, combining and adjusting audio clips, to align and match them with the video scenes.

description: Ein Sensor benötigt eine Arbeitsfrequenz in UHF-Bereich und liegt damit innerhalb der Frequenzen, die für Luftfahrtanwendungen begrenzt sind. Wird er pulsmoduliert statt kontinuierlich betrieben, so erzeugt er weniger mittlere Leistung. Der Anzeigewert eines Funkstörmessempfängers richtet sich jedoch nach der Reaktion des Bewertungsfilters und folgt nur bei der Mittelwert-Bewertung der mittleren Leistung. Die Normen ED- 14/DO - 160 erfordern die Anwendung der Spitzenwert-Bewertung, was durch die Erfassung des Amplitudenmaximums innerhalb der Verweildauer ein scharfes Kriterium ist. Hier reduziert sich der Anzeigewert wenig, wenn das Verhältnis von Einschaltdauer zu Periode der Modulation größer als 0,01 ist.

description: Es wurde eine neue Methode zur Messung der Störfestigkeit von IC's vorgestellt, die es erlaubt, die Störfestigkeit getrennt für das elektrische und magnetische Feld zu bewerten. Diese Methode verwendet eine definierte Massefläche, einen Distanzring und zwei separate Feldquellen zur Erzeugung des elektrischen bzw. magnetischen Prüffeldes. Das Testboard mit dem IC wird in die Massefläche eingelegt und anschließend eine der Feldquellen unter Verwendung des Distanzringes über dem IC positioniert. Die Höhe des Distanzringes bestimmt dabei den Abstand zwischen der Feldquelle und dem IC. Da sich der IC bei dieser Methode im Nahfeld der Quelle befindet, kann die Messung der Störfestigkeit getrennt für das elektrische und magnetische Feld erfolgen und damit der Störmechanismus näher untersucht werden. Diese Methode bietet sich daher als Ergänzung zur Messung in der TEM-Zelle nach DINEN62132-2 an. Die vorgestellte Methode wurde verwendet, um die Schirmwirkung auf IC-Ebene zu untersuchen. Dabei wurde zwischen der Schirmwirkung gegenüber dem elektrischen und dem magnetischen Feld unterschieden. Im Rahmen der Untersuchungen wurden verschiedene Schirmkonfigurationen und Materialien verwendet. Die gewonnenen Ergebnisse zeigen sehr anschaulich, welche Schirmkonfigurationen zur Schirmung elektrischer bzw. magnetischer Felder geeignet sind.
