description: The Schrodinger functional is used to define a renormalised coupling for pure SU(4) Yang-Mills theory, with Wilson action and suitably selected boundary conditions on the link field. The coupling, which runs with the size of the lattice, is then determined by a finite-size scaling technique through a large range of momenta, thereby allowing a connection to be made between the high energy regime and the low energy non-perturbative regime, where contact is made with the physical scale of the theory. Using data from previous SU(2) and SU(3) simulations obtained with the same technique, the running of the 't Hooft coupling defined through the Schrodinger functional is studied, and we check whether the large-N expectation that g^2*N is a universal function of the energy scale E holds down to energies of the order of the string tension. Finally, we determine Lambda_SF in units of the string tension as a function of N at leading order in 1/N^2.

description: Plastic scintillators are widely used as particle detectors in many fields, mainly, medicine, particle physics and astrophysics. Traditionally, they are coupled to a photo-multplier (PMT) but now silicon photo-multipliers (SiPM) are evolving as a promising robust alternative, specially in space born experiments since plastic scintillators may be a light option for low Earth orbit missions. Therefore it is timely to make a new analysis of the optimal design for experiments based on plastic scintillators in realistic conditions in such a configuration. We analyze here their response to an isotropic flux of electron and proton primaries in the energy range from 1 MeV to 1 GeV, a typical scenario for cosmic ray or space weather experiments, through detailed GEANT4 simulations. First, we focus on the effect of increasing the ratio between the plastic volume and the area of the photo-detector itself and, second, on the benefits of using a reflective coating around the plastic, the most common technique to increase light collection efficiency. In order to achieve a general approach, it is necessary to consider several detector setups. Therefore, we have performed a full set of simulations using the highly tested GEANT4 simulation tool: several parameters have been analyzed such as the energy lost in the coating, the deposited energy in the scintillator, the optical absorption, the fraction of scintillation photons that are not detected, the light collection at the photo-detector, the pulse shape and its time parameters and finally, other design parameters as the surface roughness, the coating reflectivity and the case of a scintillator with two decay components. This work could serve as a guide on the design of future experiments based on the use of plastic scintillators.

Decuplet Contributions to Hyperon Axial Vector Form Factors

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

description: We consider the predictions of chiral perturbation theory for $SU(3)$ breaking in the axial vector form factor $g_1$ measured in semileptonic hyperon decays. We confirm that if only octet baryon intermediate states are included, the non-analytic corrections are $\sim 100\%$. These corrections are dominated by an $SU(3)$-symmetric wavefunction renormalization, which explains the fact that the ``corrected'' predictions still fit the data well. We argue that the large corrections are nonetheless strong evidence that this chiral expansion is breaking down. Following a recent suggestion of Jenkins and Manohar, we then include contributions from decuplet baryon intermediate states. Unlike these authors, we do not neglect the octet--decuplet mass difference $Δ$. We find that the effects of $Δ\ne 0$ significantly change the pattern of corrections: we still find that the decuplet corrections can cancel the large octet contributions in a non-trivial way, but the corrections no longer favor the $SU(6)$ values of the axial couplings. We also argue that $D$ and $F$ axial couplings cannot be reliably extracted from calculations which keep only the non-analytic corrections.

Examining Frontal Lobe Functions and their ‘Family Resemblance

description: The frontal lobes constitute approximately one-third of the total brain area. It is not surprising then to learn that the frontal lobes are important in a variety of functions. Research has shown us that the frontal lobes play a role in motor functions, divergent thinking, environmental control of behavior, temporal memory, spatial orientation, social behavior, olfaction, and face movements. Given this wide variety of functions, researchers have found it a difficult and puzzling task to tie them together into some sort of coherent framework that would describe an overall function of the frontal lobes. Is there any sort of 'family resemblance' among these different functions? Are these various functions related in some way? Throughout this paper I will first discuss the functions of the frontal lobes and second discuss the 'family resemblance' among these functions.

Helmholtz Association
Helmholtz Metadata Collaboration

description: In 2019, the Helmholtz Association of German Research Centres set up the Helmholtz Metadata Collaboration (HMC) platform to tackle the topic of metadata within its organization. HMC was established with the mission to leverage the visibility and reusability of data across the Helmholtz Association and beyond, and to turn FAIR (Findable, Accessible, Interoperable, Reusable) research data into reality. The vision is to create a sustainable, distributed, semantically enriched FAIR Helmholtz data space.

Over the last four years we have put great efforts into reaching our goals. Our work is focussed on three key strategic areas:

(1)   Assessing and monitoring the state of FAIR data across HelmholtzThrough a mixed method approach we are continuously learning about the data ecosystem within Helmholtz and beyond and communicate them to relevant stakeholders. Those findings enable individuals and institutions alike to identify concrete actions to improve data handling. Measures and results so far include community survey conducted, a FAIR data dashboard and an information portal established.

(2)   Facilitating connectivity of Helmholtz research dataThe Helmholtz data space will enable scientists to easily find and combine data from different scientific domains. Within our platform its technical and social features were define d. Several tools were developed and deployed, workflows for e.g., the backbone for FAIR Digital Objects were implemented and a first Helmholtz Knowledge Graph (connecting data from 32 data providers) was released.  

(3)   Transforming (meta)data recommendations into implementations. Our stakeholders act on different levels of the Helmholtz research data ecosystem. Through offering practical advice, training and guidelines on implementing community recommendations we aim to bridge different levels in knowledge, communication and technical capabilities between them and harmonize the approaches across Helmholtz. Further, annual calls for community projects are used to implement specific community solutions.

Our work is closely intertwined with national (e.g. National Research Infrastructure Germany (NFDI)) and international (e.g. EOSC, RDA) efforts which is ensured through collaboration with the relevant partners.

We want to present our approach, some of our results and the lessons learnt on our road to FAIR. By sharing our experiences with the RDA-DE community, we want to engage in an active discussion on (meta)data, relevant stakeholder and how to shape our path to a FAIR data ecosystem together.

description: The internal structure of hadrons is important for a variety of topics, including the hadron form factors, proton spin and spin asymmetry in polarized proton scattering. For a systematic study generalized parton distributions (GPDs) encode important information on hadron structure in the entire impact parameter space. We report on a computation of nucleon GPDs based on simulations with two dynamical non-perturbatively improved Wilson quarks with pion masses down to 350MeV. We present results for the total angular momentum of quarks with chiral extrapolation based on covariant baryon chiral perturbation theory.

description: The original \bnum -(or $\barν_τ$-) energy spectrum from the gravitational collapse of a star has a larger average energy than the spectrum for \bnue since the opacity of \bnue exeeds that of \bnum (or $ν_τ$). Flavor neutrino conversion, \bnue $\leftrightarrow$ \bnum, induced by lepton mixing results in partial permutation of the original \bnue and \bnum spectra. An upper bound on the permutation factor, $p \leq 0.35$ (99$\%$ CL) is derived using the data from SN1987A and the different models of the neutrino burst. The relation between the permutation factor and the vacuum mixing angle is established, which leads to the upper bound on this angle. The excluded region, $\sin^2 2θ> 0.7 - 0.9$, covers the regions of large mixing angle solutions of the solar neutrino problem: ``just-so" and, partly, MSW, as well as part of region of $ν_{e} - ν_μ$ oscillation space which could be responsible for the atmospheric muon neutrino deficit. These limits are sensitive to the predicted neutrino spectrum and can be strengthened as supernova models improve.

Software Automation

description: We present a unique implementation of python coding in an asynchronous object-oriented framework to fully automate the process of collecting data with the George Mason University Observatory’s 0.8-meter telescope. The goal of this project is to streamline the process of collecting research data and monitoring weather, most often for follow-up observations for the TESS mission. We have automated slews and dome movements, CCD exposures, saving FITS images, focusing and guiding on the target, and taking calibration images (darks and flats). We also have automated periodically checking weather conditions to automate the decision-making involved in whether a shutdown is necessary. We are now able to input the specifications of the desired target in a user-friendly GUI that generates an input configuration file and launches the command-line code at the beginning of the night. The code, in its current state, has been tested and used for observations without error on at least 110 nights.

description: Interplay of spin-orbit coupling and vibronic coupling on heavy $d^1$ site of cubic double perovskites is investigated by ab initio calculations. The stabilization energy of spin-orbital-lattice entangled states is found comparable to or larger than the exchange interactions, suggesting the presence of Jahn-Teller dynamics in the systems. In Ba$_2$YMoO$_6$, the pseudo JT coupling enhances the mixing of the ground and excited spin-orbit multiplet states, which results in strong temperature dependence of effective magnetic moments. The entanglement of the spin and lattice degrees of freedom induces a strong magneto-elastic response. This multiferroic effect is at the origin of the recently reported breaking of local point symmetry accompanying the development of magnetic ordering in Ba$_2$NaOsO$_6$.

Nonperturbative Conditions for Local Weyl Invariance on a Curved World Sheet

description: We investigate Weyl anomalies on a curved world sheet to second order in a weak field expansion. Using a local version of the exact renormalization group equations, we obtain nonperturbative results for the tachyon/graviton/dilaton system. We discuss the elimination of redundant operators, which play a crucial role for the emergence of target space covariance. Performing the operator product expansion on a curved world sheet allows us to obtain the nonperturbative contributions to the dilaton $β$ function. We find the $β$ functions, after suitable field redefinitions, to be related to a target space effective action through a $κ$ function involving derivatives. Also we can establish a nonperturbative Curci-Paffuti relation including the tachyon $β$ function.

Subjects: subject: 530 Physik

description: In classical thermodynamic processes the unavoidable presence of irreversibility, quantified by the entropy production, carries two energetic footprints: the reduction of extractable work from the optimal, reversible case, and the generation of a surplus of heat that is irreversibly dissipated to the environment. Recently it has been shown that in the quantum regime an additional quantum irreversibility occurs that is linked to decoherence into the energy basis. Here we employ quantum trajectories to construct distributions for classical heat and quantum heat exchanges, and show that the heat footprint of quantum irreversibility differs markedly from the classical case. We also quantify how quantum irreversibility reduces the amount of work that can be extracted from a state with coherences. Our results show that decoherence leads to both entropic and energetic footprints which both play an important role in the optimization of controlled quantum operations at low temperature.

In classical thermodynamics irreversibility occurs whenever a non-thermal system is brought into contact with a thermal environment. Using quantum trajectories the authors here establish two energetic footprints of quantum irreversible processes, and find that while quantum irreversibility leads to the occurrence of a quantum heat and a reduction of work production, the two are not linked in the same manner as the classical laws of thermodynamics would dictate.

description: This paper theoretically investigates the relations between the structure of relativistic jets and produced synchrotron images, by using a steady axisymmetric force-free jet model. We especially focus on the limb-brightened jets that are largely symmetric to the jet axes and observed in some active galactic nuclei such as M87, Mrk~501, Cyg~A, and 3C84. We find that symmetrically limb-brightened images can be produced when magnetic field lines of the jet penetrate a fast-spinning black hole as motivated by the Blandford-Znajek mechanism. On the other hand, jets with magnetic field lines that pass through a slowly spinning black hole or the Keplerian accretion disk produce highly asymmetric radio images. In addition, the edge of a counter jet tends to be luminous in the accretion-disk model even for rather small viewing angles, which may be problematic for some observed jets. We also suggest that the site of particle accelerations in relativistic jets can be constrained by fitting the radio images to observations. This kind of study focusing on the jet images far away from the central engine is complimentary to those concentrating directly on the innermost region with upcoming data of the Event Horizon Telescope.

description: We employ a mesoscopic model for studying aggregation processes of protein-like hydrophobic-polar heteropolymers. By means of multicanonical Monte Carlo computer simulations, we find strong indications that peptide aggregation is a phase separation process, in which the microcanonical entropy exhibits a convex intruder due to nonnegligible surface effects of the small systems. We analyze thermodynamic properties of the conformational transitions accompanying the aggregation process from the multicanonical, canonical, and microcanonical perspective. It turns out that the microcanonical description is particularly advantageous as it allows for unraveling details of the phase-separation transition in the thermodynamic region, where the temperature is not a suitable external control parameter anymore.

Dynamical density functional theory for the evaporation of droplets of nanoparticle suspension

description: We develop a lattice gas model for the drying of droplets of a nanoparticle suspension on a planar surface, using dynamical density functional theory (DDFT) to describe the time evolution of the solvent and nanoparticle density profiles. The DDFT assumes a diffusive dynamics but does not include the advective hydrodynamics of the solvent, so the model is relevant to highly viscous or near to equilibrium systems. Nonetheless, we see an equivalent of the coffee-ring stain effect, but in the present model it occurs for thermodynamic rather the fluid-mechanical reasons. The model incorporates the effect of phase separation and vertical density variations within the droplet and the consequence of these on the nanoparticle deposition pattern on the surface. We show how to include the effect of slip or no-slip at the surface and how this is related to the receding contact angle. We also determine how the equilibrium contact angle depends on the microscopic interaction parameters.

description: We report the full control over the internal states of ultracold $^{23}$Na$^{87}$Rb molecules, including vibrational, rotational and hyperfine degrees of freedom. Starting from a sample of weakly bound Feshbach molecules, we realize the creation of molecules in single hyperfine levels of both the rovibrational ground and excited states with a high-efficiency and high-resolution stimulated Raman adiabatic passage. Starting from the rovibrational and hyperfine ground state, we demonstrate rotational and hyperfine control with one- and two-photon microwave spectroscopy. This achievement of fully controlling the molecular internal states paves the way to study state dependent molecular collisions and state controlled chemical reactions.

description: Kindness can boost happiness and wellbeing. It can benefit individuals (e.g., increasing resilience) as well as society (e.g., increasing trust). With digital technology permeating our daily lives, there are increasing opportunities for such technology to enable, mediate, and amplify kindness in society. In this paper, we propose kind computing, a new computing paradigm that explicitly incorporates kindness into the development and use of digital technology. We envisage software engineering as a discipline that can deliver such technology. However, software engineering techniques do not provide explicit abstractions, formalisms, and tools to consider, analyse, and implement software that delivers such technology. With reference to related work, we elaborate on kind computing and the role of software engineering in enabling it, identify open research challenges, elicit three categories of kind computing requirements, and sketch a research agenda for future work.

description: We study spectral statistics in spatially extended chaotic quantum many-body systems, using simple lattice Floquet models without time-reversal symmetry. Computing the spectral form factor $K(t)$ analytically and numerically, we show that it follows random matrix theory (RMT) at times longer than a many-body Thouless time, $t_{\rm Th}$. We obtain a striking dependence of $t_{\rm Th}$ on the spatial dimension $d$ and size of the system. For $d>1$, $t_{\rm Th}$ is finite in the thermodynamic limit and set by the inter-site coupling strength. By contrast, in one dimension $t_{\rm Th}$ diverges with system size, and for large systems there is a wide window in which spectral correlations are not of RMT form.

Die gesundheitliche Versorgung geistig behinderter Menschen. Eine qualitative Erhebung der Sichtweisen von Bezugspersonen und professionellen Akteuren
Creators: name: Thienel, Christine

Subjects: subject: 610

description: Hintergrund: Studienergebnisse weisen darauf hin, dass die gesundheitliche Versorgung geistig behinderter Menschen defizitär verläuft. Dies trifft auch auf Deutschland zu, obwohl hier bereits 2009 die UN-Behindertenrechtskonvention ratifiziert wurde und zahlreiche politische Aktivitäten zur Umsetzung folgten. Hinweise auf Anpassungsmöglichkeiten der vorhandenen nationalen Versorgungsstrukturen sind daher von hoher Bedeutung. Dafür ist es zunächst notwendig zu wissen, wie sich die Versorgungssituation aktuell darstellt. Methodik: Zur Bestandsaufnahme der gesundheitlichen Versorgungssituation geistig behinderter Menschen in Deutschland wurde eine explorative qualitative Untersuchung mittels teilstandardisierter Leitfadeninterviews durchgeführt. Befragt wurden Bezugspersonen der Betroffenen sowie professionelle Akteure der Versorgung. Die Auswertung erfolgte mittels eines strukturierenden inhaltsanalytischen Vorgehens in Anlehnung an Mayring und Gläser & Laudel. Ergebnisse: Hinweise auf Herausforderungen in Bezug zur gesundheitlichen Versorgung der Zielgruppe finden sich im Kontext der Inanspruchnahme, in Bezug auf den Zeitbedarf der Betroffenen und die Zeitressourcen der Akteure sowie in Bezug auf die Kooperation zwischen den Beteiligten. Hinweise auf Einflussfaktoren zeigten sich auf drei Ebenen. Auf Ebene der Betroffenen stehen eine häufig begrenzte Compliance und Kommunikationsfähigkeit sowie Verhaltensauffälligkeiten im Vordergrund. Auf Ebene der Akteure stellen der Umgang mit den Betroffenen sowie die Qualifikation der Akteure zentrale Einflussfaktoren dar. Auf Systemebene sind personelle und zeitliche Ressourcen sowie das aktuelle Vergütungssystem relevante Einflussfaktoren. In den Schilderungen der Interviewpartner*innen finden sich zudem zahlreiche Hinweise auf Veränderungspotentiale. Fazit: Die Ergebnisse deuten an, dass es bisher in Deutschland, trotz zahlreichen Aktivitäten, nicht gelungen ist die Vorgaben der UN-BRK zur Gesundheitsversorgung von Menschen mit Behinderung umzusetzen. Weitere Forschungsaktivitäten sind notwendig, um die bestehenden Versorgungsstrukturen eingehend zu analysieren und Möglichkeiten für eine Anpassung an die spezifischen Bedarfe geistig behinderter Menschen aufzuzeigen.

description: Applying the HSD transport approach to charmonium dynamics within the 'hadronic comover model' and the 'QGP melting scenario', we show that the suppression pattern seen at RHIC cannot be explained by the interaction with baryons, comoving mesons and/or by color screening mechanism. The interaction with hadrons in the late stages of the collision (when the energy density falls below the critical) gives a sizable contribution to the suppression. On the other hand, it does not account for the observed additional charmonium dissociation and its dependence on rapidity. Together with the failure of the hadron-string models to reproduce high v2 of open charm mesons, this suggests strong pre-hadronic interaction of c-cbar with the medium at high energy densities.

description: For a quantum system subject to external parameters, the Berry phase is an intra-level property, which is gauge invariant module $2π$ for a closed loop in the parameter space and generally is non-quantized. In contrast, we define a inter-band character $Θ$ for a closed loop, which is gauge invariant and quantized as integer values. It is a quantum mechanical analogy of the Euler character based on the Gauss-Bonnet theorem for a manifold with a boundary. The role of the Gaussian curvature is mimicked by the difference between the Berry curvatures of the two levels, and the counterpart of the geodesic curvature is the quantum geometric potential which was proposed to improve the quantum adiabatic condition. This quantized inter-band character is also generalized to quantum degenerate systems.

description: This paper presents a framework for fast and robust motion planning designed to facilitate automated driving. The framework allows for real-time computation even for horizons of several hundred meters and thus enabling automated driving in urban conditions. This is achieved through several features. Firstly, a convenient geometrical representation of both the search space and driving constraints enables the use of classical path planning approach. Thus, a wide variety of constraints can be tackled simultaneously (other vehicles, traffic lights, etc.). Secondly, an exact cost-to-go map, obtained by solving a relaxed problem, is then used by A*-based algorithm with model predictive flavour in order to compute the optimal motion trajectory. The algorithm takes into account both distance and time horizons. The approach is validated within a simulation study with realistic traffic scenarios. We demonstrate the capability of the algorithm to devise plans both in fast and slow driving conditions, even when full stop is required.

description: At Carnegie Mellon University in Silicon Valley, the graduate master program ends with a practicum project during which students serve as software engineering consultants for an industry client. In this context, students are challenged to demonstrate their ability to work on self-managing and self-organizing teams. This paper presents a field study of the Software Engineering Method and Theory (SEMAT) Essence framework. The objective is to evaluate the effectiveness of the Essence’s novel state-based monitoring and goal-driven steering approach. The researchers conducted the study on seven graduate master student teams applying the approach throughout their practicum projects. The research methodology involves weekly observation and recording of each team’s state progression and collecting students’ reflection on the application of the approach. The main result validates that the approach provides student teams with a holistic, lightweight, non-prescriptive and method-agnostic way to monitor progress and steer projects, as well as an effective structure for retrospective and risk management. The monitoring and steering mechanisms are most effective during project initiation. The benefit decreases later in the project lifecycle. The conclusion is that the approach adds value to the whole learning and teaching experience and hence could be leveraged in software engineering education.

description: Many studies have shown that cells use temporal dynamics of signalling molecules to encode information. One particular class of temporal dynamics is persistent and transient signals, i.e. signals of long and short durations respectively. It has been shown that the coherent type-1 feedforward loop with an AND logic at the output (or C1-FFL for short) can be used to discriminate a persistent input signal from a transient one. This has been done by modelling the C1-FFL, and then use the model to show that persistent and transient input signals give, respectively, a non-zero and zero output. Instead of assuming the structure of C1-FFL, this paper shows that it is possible to deduce the C1-FFL model from the requirement of discriminating a persistent signal. We do this by first formulating a statistical detection problem of distinguishing persistent signals from transient ones. The solution of the detection problem is to compute the log-likelihood ratio of observing a persistent signal to a transient signal. We show that, if this log-likelihood ratio is positive, which happens when the signal is likely to be persistent, then it can be approximately computed by a C1-FFL. Although the capability of C1-FFL to discriminate persistent signals is known, this paper adds an information processing interpretation on how a C1-FFL works as a detector of persistent signals.

description: In this article, we investigate the motion of a spinning particle at a constant inclination, different from the equatorial plane, around a Kerr black hole. We mainly explore the possibilities of stable circular orbits for different spin supplementary conditions. The Mathission-Papapetrau's equations are extensively applied and solved within the framework of linear spin approximation. We explicitly show that for a given spin vector of the form $S^{a} = \left(0,S^r,S^θ,0\right)$ , there exists an unique circular orbit at $(r_c,θ_c)$ defined by the simultaneous minima of energy, angular momentum and Carter constant. This corresponds to the Innermost Stable Circular Orbit (ISCO) which is located on a non-equatorial plane. We further establish that the location ($r_c,θ_c$) of the ISCO for a given spinning particle depends on the radial component of the spin vector ($S^r$) as well as the angular momentum of the black hole ($J$). The implications of using different spin supplementary conditions are investigated.

Revisiting questions i asked my mother in Conversation with Di Brandt
Creators: name: Weingarten, Jeffrey Aaron
Publisher: name: Canadian Literature
Year: 2018

description: Reissued in Fall 2015 by Turnstone Press, Di Brandt's questions i asked my mother explores the ethical, moral, and existential queries of a lyric persona simultaneously youthful and adult, a woman whose perspective constantly oscillates between her footing in the past—surrounded by her family in Reinland, Manitoba—and in the immediate present, at a time when she experiences her distance from those times, places, and people. In its time, these aspects of the text brought Brandt into dialogue with topical issues such as second-wave feminism and Canadian multiculturalism. Thirty years later, Brandt’s sequence retains its power because of that dialogue. This interview with Brandt was conducted in June and July 2015.
