description: A Bose-Hubbard Hamiltonian, modeling cold bosons in an optical lattice, is used to simulate the dynamics of interacting open quantum systems as subsystems a larger closed system, avoiding complications like the introduction of baths, complex absorbing potentials or absorbing boundaries. The numerically exact unitary dynamics is compared with effective descriptions of the subsystems based on non-Hermitian Hamiltonians or Lindblad master equations. The validity of popular models with constant decay rates is explicitly analyzed for decaying single and double wells. In addition we present a discrete lattice version of the Siegert approximation method for calculating decay rates.

Year: 2019

description: Niemand hat die Klage darüber, dass mit der patriarchalen Sprache keine weibliche Stimme zu erheben ist, schöner gesungen als Ingeborg Bachmann in Malina. „Hier ist keine Frau“ und „es war Mord“ endet der Roman. Seit Anfang des Jahres diskutieren wir endlich wieder die Rolle der Sprache für eine gendergerechte Welt und den potenziellen Beitrag der Literatur. Bereits kurz vor und in der Folge der heftigen Angriffe gegen gendergerechte Sprache zum Weltfrauentag 2019 (vgl. Hartmann 2019) meldeten sich auch Autorinnen und Autoren zu Wort. Bis dahin schien das Thema in der aktuellen gesellschaftlichen und literarischen Debatte bestenfalls eine Nebenrolle zu spielen.
So postuliert Margarethe Stokowski in Die letzten Tage des Patriarchats (2018), dem derzeit vieldiskutierten Buch des deutschsprachigen Feminismus, den radikalen sozialen Wechsel jeder weiblichen Biografie „wenn man schwanger wird“. Mag die Formulierung auch als grammatikalisch korrekt das Lektorat passiert haben, treibt sie doch die ganze Absurdität des generischen Maskulinums auf die Spitze, als permanente Zumutung an Frauen, sich gemeint zu fühlen, wo sie sprachlich nicht repräsentiert werden – selbst, wenn das Maskulinum gar nicht existiert.

description: The polarization switch of a free-electron laser (FEL) is of great importance to the user scientific community. In this paper, we investigate the generation of controllable polarization FEL from two well-known approaches for Dalian coherent light source, i.e., crossed planar undulator and elliptical permanent undulator. In order to perform a fair comparative study, a one-dimensional time-dependent FEL code has been developed, in which the imperfection effects of an elliptical permanent undulator are taken into account. Comprehensive simulation results indicate that the residual beam energy chirp and the intrinsic FEL gain may contribute to the degradation of the polarization performance for the crossed planar undulator. And the elliptical permanent undulator is not very sensitive to the undulator errors and beam imperfections. Meanwhile, with proper configurations of the main planar undulators and additional elliptical permanent undulator section, circular polarized FEL with pulse energy exceeds 100 $μ$J could be achieved at Dalian coherent light source.

Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: The equation determining whether a projective structure admits a connection in its given projective class that has skew-symmetric Ricci tensor is an overdetermined system of semi-linear partial differential equations which we call the projective Einstein-Weyl (pEW) equation. In 2-dimensions, we give local obstructions for projective surfaces to admit such a connection in its projective class. The obstructions are the resultants of polynomial equations that have to be satisfied for there to admit any pEW solution.

On the Temporal Evolution of the Disc Counterpart of Type II Spicules in Quiet Sun

description: The type II spicule has been speculated to provide enough hot plasma to play an important role in the mass loading and heating of the corona. We analyse the disc counterpart to type II spicules, RBEs, in three high quality datasets from CRISP at the SST. In a quiet Sun region at disc centre we find lower Doppler velocities, 15-40km/s, and Doppler widths, 2-15km/s, of RBEs than in earlier coronal hole studies, 30-50km/s and 7-23km/s, respectively. We examine the spatial dependence of Doppler velocities and widths along RBE axes and conclude that there is no clear trend over the FOV or in individual RBEs in quiet Sun at disc centre. These differences with previous coronal hole studies are attributed to the more varying magnetic field configuration in quiet Sun conditions. Using an extremely high cadence dataset allowed us to improve greatly on the determination of lifetimes of RBEs, found to range from 5 to 60s with an average of 30s, as well as the transverse motions in RBEs, with transverse velocities up to 55km/s and averaging 12km/s. Furthermore, our measurements of the recurrence rates of RBEs provide important new constraints on coronal heating by spicules. We also see many examples of a sinusoidal wave pattern in the transverse motion with periods averaging 54s and amplitudes from 21.5 to 129km, agreeing well with previous studies of wave motion in limb spicules. We interpret the appearance of RBEs over their full length within a few seconds as the result of a combination of three kinds of motions as reported earlier for spicules. Finally, we look at the temporal connection between Ha and Ca 8542 RBEs and find Ca 8542 in addition to being located closer to the footpoint also appear before the Ha RBE. This connection supports the idea that heating occurs in spicules and contribute more weight to the prominence of spicules as a source for heating and mass loading of the corona.

Publisher: name: Zenodo
Year: 2024

description: We are pleased to announce the launch of the Energy and Resource System Modeling Proficiency Badge Scheme, a collaborative initiative born from the partnership between RE-INTEGRATE and Climate Compatible Growth (CCG). This innovative certification system aims to standardise and recognize modelling proficiency across various tools and institutions, with an initial focus on OSeMOSYS and CLEWs.

Objective: To establish a standardised certification system that benchmarks modelling proficiency in energy and resource system modelling tools - initially OSeMOSYS and CLEWs but with plans to incorporate other tools too -  through a tiered badge system: Bronze, Silver & Gold that signifies modelling competency. An additional two-levelled ‘Instructors’ badge is also included to denote capacity building and instructing competence. Initially, this system will  be deployed in a  CCG/RE-INTEGRATE context - with a longer term aim of the badge system to become relevant for wider practitioners beyond these organisations.

description: Results for the Lambda N and Sigma N interactions obtained at next-to-leading order in chiral effective field theory are reported. At the order considered there are contributions from one- and two-pseudoscalar-meson exchange diagrams and from four-baryon contact terms without and with two derivatives. SU(3) flavor symmetry is imposed for constructing the hyperon-nucleon interaction while the explicit SU(3) symmetry breaking by the physical masses of the pseudoscalar mesons (pi, K, eta) is taken into account. An excellent description of the hyperon-nucleon system can be achieved at next-to-leading order. It is on the same level of quality as the one obtained by the most advanced phenomenological hyperon-nucleon interaction models.

description: Surface temperature inhomogeneities in classical T Tauri stars (CTTS) induced by magnetic activity and mass accretion lead to rotational modulation of both photometric and spectroscopic parameters of these stars. Using the extended photometric catalogue by Grankin et al. (2007), we have derived the periods and amplitudes of the rotational modulation of brightness and color for 31 CTTS; for six of them, the periods have been revealed for the first time. The inclinations of the rotation axis and equatorial rotational velocities of CTTS have been determined. We show that the known periods of brightness variations for some of the CTTS are not the axial rotation periods but are the Keplerian periods near the inner boundary of the dusty disk. We have found that the angular velocity of CTTS with a mass of 0.3 - 3 M_sun in the Taurus-Auriga complex remains constant in the age range 1 - 10 Myr. CTTS on radiative evolutionary tracks rotate faster than completely convective CTTS. The specific angular momentum of CTTS depends on the absolute luminosity in the Hα- line.

description: In a number of estimation problems in bioinformatics, accuracy measures of the target problem are usually given, and it is important to design estimators that are suitable to those accuracy measures. However, there is often a discrepancy between an employed estimator and a given accuracy measure of the problem. In this study, we introduce a general class of efficient estimators for estimation problems on high-dimensional binary spaces, which representmany fundamental problems in bioinformatics. Theoretical analysis reveals that the proposed estimators generally fit with commonly-used accuracy measures (e.g. sensitivity, PPV, MCC and F-score) as well as it can be computed efficiently in many cases, and cover a wide range of problems in bioinformatics from the viewpoint of the principle of maximum expected accuracy (MEA). It is also shown that some important algorithms in bioinformatics can be interpreted in a unified manner. Not only the concept presented in this paper gives a useful framework to design MEA-based estimators but also it is highly extendable and sheds new light on many problems in bioinformatics.

title: Rural landscapes and the World Heritage List
Creators: name: L'Erario, Andrea
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Since 1992 “Cultural landscapes” of outstanding value are recognized by the Operational Guidelines of the World Heritage Convention and some rural landscapes are inscribed as in the World Heritage List.

However, “ordinary” rural landscapes are present in several UNESCO Properties, also in “Natural” or “Mixed”. According to the approaches of the European Landscape Convention, regarding the importance of preserving both “ordinary” and “outstanding” landscapes, and of the ICOMOS-IFLA Principles regarding Rural Landscapes as Heritage, which affirms that rural landscapes are “one of the most common types of continuing cultural landscapes”, the overall protection of several UNESCO Properties can be reached by preserving the component related to “ordinary” rural systems, managed by local people with traditional methods. Their safeguarding becomes fundamental for the overall protection of the integrity of the UNESCO Properties.

For this reason, the need of providing an updated overview regarding presence and state of preservation of rural landscapes in all UNESCO Properties – Cultural heritage (monuments, groups of buildings and sites), Natural heritage and Mixed Sites – brought to a wide survey aimed at supporting the assessment of the effectiveness of the Management Plans or National policies for the UNESCO Sites conservation.

The research illustrates that rural systems, classified according the WRLI classification, are present in over the 30% of UNESCO Sites. The survey considers several kinds of rural systems (including gathering/hunting by indigenous people).

The research considers: 1. Rural landscape systems strictly related to the Sites management from a functional point of view (agro-environmental, cultural, economic, …); 2. Rural landscapes related to the protected Property from a perceptive point of view, in particular visual, whose preservation is fundamental for the integrity of the Site itself; 3. Relict rural landscapes.

This study is part of a wider research aimed at understanding the preservation level of rural heritage in UNESCO Properties.

description: We outline a general method for computing nuclear capture reactions on the lattice. The method consists of two major parts. In this study we detail the second part which consists of calculating an effective two-body capture reaction on the lattice at finite volume. We solve this problem by calculating the two-point Green's function using an infrared regulator and the capture amplitude to a two-body bound state. We demonstrate the details of this method by calculating on the lattice the leading M1 contribution to the radiative neutron capture on proton at low energies using pionless effective field theory. We find good agreement with exact continuum results.

description: We study the Renyi entropy in the finite temperature crossover regime of a Hubbard chain using quantum Monte Carlo. The ground state entropy has characteristic features such as a logarithmic divergence with block size and $2\kF$ oscillations that are a hallmark of its Luttinger liquid nature. The interplay between the (extensive) thermal entropy and the ground state features is studied and we analyze the temperature induced decay of the amplitude of the oscillations as well as the scaling of the purity. Furthermore, we show how the spin and charge velocities can be extracted from the temperature dependence of the Renyi entropy, bridging our findings to recent experimental proposals on how to implement the measurement of Renyi entropies in cold atom system. Studying the Renyi mutual information, we also demonstrate how constraints such as particle number conservation can induce persistent correlations visible in the mutual information even at high temperature.

description: We argue that the observed large-scale cosmic microwave anomalies, discovered by WMAP and confirmed by the Planck satellite, are most naturally explained in the context of a marginally-open universe. Particular focus is placed on the dipole power asymmetry, via an open universe implementation of the large-scale gradient mechanism of Erickcek et al. Open inflation models, which are motivated by the string landscape and which can excite `super-curvature' perturbation modes, can explain the presence of a very-large-scale perturbation that leads to a dipole modulation of the power spectrum measured by a typical observer. We provide a specific implementation of the scenario which appears compatible with all existing constraints.

description: Traditional practices of cultivating and gathering of food in rural areas embody the entangled dimensions of nature and culture. These traditional landscapes and waterscapes, living repositories of bio-cultural diversity, have much to teach us about resilience. This is manifest in the intangible and tangible cultural heritage associated with these places, including the physical shaping of the landscape and water systems; their complex systems of traditional knowledge, governance and management practices; and their sacred dimensions.

This workshop will build on sessions recently convened within the Culture-Nature/Nature-Culture Journeys ICOMOS Scientific Symposium (2017) and the IUCN World Conservation Congress (2016), which provided an opportunity to share experience from diverse regions on the theme of constructing resilience.In this session we will take the dialogue further, and will explore how frameworks being developed through global dialogues (such as the indicators of resilience in socio-ecological production landscapes used by the International Partnership of the Satoyama Initiative, or IPSI) can contribute to strategies for sustaining rural landscapes in diverse settings.
A Review of Hot Executive Functions in Preschoolers

Subjects: hot executive functions; cool executive functions; delay of gratification; Iowa Gambling task; preschool

description: Executive functions (EF), a term used to refer to a large number of abilities involved in self-regulation, has become an important focus of research in early development. A distinction between cool and hot EF is often made based on whether a problem involves abstract versus motivational aspects. While research on cool EF in preschoolers is abundant, relatively little work has been done on hot EF abilities. The current paper focuses primarily on research utilizing two hot EF tasks: the delay of gratification task (Mischel et al. 1989) and preschool variants of the Iowa Gambling task (Bechara et al. 1994). The pattern of findings clearly indicate age improvements in hot EF during the preschool period. Finally, processes involved in hot EF tasks are placed into the broader context of early EF and self-regulation and areas warranting future research are discussed.

description: Based on a recently started programme, we report the first search for intranight optical variability among radio-quiet weak-line-quasars (RQWLQs). Eight members of this class were observed on 13 nights in the R-band, such that each source was monitored continuously at least once for a minimum duration of about 3.5 hours, using the recently installed 130 cm telescope at Devasthal, India. Statistical analysis of the differential light curves was carried out using two versions of the F-test. Based on the INOV data acquired so far, the radio-quiet WLQ population appears to exhibit stronger INOV activity as compared to the general population of radio-quiet quasars (RQQs), but similar to the INOV known for radio-loud quasars of non-blazar type. To improve upon this early result, as well as extend the comparison to blazars, a factor of ?2 improvement in the INOV detection threshold would be needed. Such efforts are underway, motivated by the objective to search for the elusive radio-quiet blazars using INOV observations.

description: Rural landscapes with interconnected CultureNature heritage value have much to contribute to the resiliency and sustainability of food production, use of renewable natural resources and overall well-being of communities. Their contributions have had limited recognition within the global framework for the UN Sustainable Development Goals (SDGs), and some reference in the UN-Habitat New Urban Agenda. Rural landscapes are addressed in SDG 11 as a type of ‘human settlement’ and Target 11.4 calls for 'strengthening efforts ‘to protect and safeguard the world’s cultural and natural heritage’. The World Rural Landscape Initiative of the ICOMOS-IFLA ISC on Cultural Landscapes (ISCCL) has compiled an ICOMOS doctrinal text of principles that advocates for more recognition of heritage values of rural landscapes and provides guidance on conservation. These principles address the CultureNature interconnectedness integral to many rural landscapes. This workshop will explore in more depth strategies for this aspect of rural landscapes in order to provide further guidance.

description: Current-phase relation in a Josephson junction formed by putting two s-wave superconductors on the same edge of a two dimensional topological insulator is investigated. We consider the case that the junction length is finite and magnetic impurity exists. The similarity and difference with conventional Josephson junction is discussed. The current is calculated in the semiconductor picture. Both the $2π$- and $4π$-period current-phase relations ($I_{2π}(ϕ), I_{4π}(ϕ)$) are studied. There is a sharp jump at $ϕ=π$ and $ϕ=2π$ for $I_{2π}$ and $I_{4π}$ respectively in the clean junction. For $I_{2π}$, the sharp jump is robust against impurity strength and distribution. However for $I_{4π}$, the impurity makes the jump at $ϕ=2π$ smooth. The critical (maximum) current of $I_{2π}$ is given and we find it will be increased by asymmetrical distribution of impurity.

description: Background:

The management and monitoring of surgical drains is an essential aspect in the management of surgical patients. Despite its importance, senior surgeons at our hospital highlighted a recurrent gap in knowledge; new trainees, and nurses’ confidence in managing surgical drains. It was hypothesised that the lack of confidence was linked to a lack of specific training.



Summary of Work:

To address this specific gap in knowledge a physical and visible training resource, accessible by the entire multidisciplinary team was created. This was accessible via a QR code which we displayed in multiple clinical areas of a single University Hospital on an A4 poster.  An initial anonymous survey was conducted collecting responses from junior doctors, nurses, and physician associates within the surgical department. This survey utilised multiple choice and free text questions relating to current knowledge of surgical drains to gather pre-intervention data to ascertain the level of knowledge of surgical drains. This information was used to design a resource covering types of drains, complications, contacts for escalation, and clinical cases. After 4 months, a post-intervention survey was completed.



Summary of Results:

14 members of the MDT responded to the pre-intervention survey, including 4 house Officers (FY1), 10 senior house officers (FY2+) and 2 physician associates. 64.3% (9/14) of participants stated that they were not confident in identifying different types of surgical drains, 42.9% (6/14) stated they did not know minimum documentation requirements and 35.7% (5/14) were unconfident in identifying common complications. Free text answers further highlighted the lack of consistent documentation of drain outputs at the time of ward round affecting clinical management. 4 participants responded to the post-intervention survey. 100% (4/4) of responses stated they were more confident in their surgical drain knowledge after utilising the resource.



Discussion and Conclusion:

Rotation is part of the universal experience of NHS teams. Our project highlights the efficacy of creating a cross-discipline, easy-access resources to help the transition of new teams onto clinical wards.



Take-Home Message:

Developing a physical learning resource available in the clinical area has the potential to enhance knowledge regarding patient care, trainee, and MDT experience.

description: Regulating emotions volitionally requires the inhibition and modification of an elicited emotional action readiness and includes phases of reflection, planning and self-regulation. The proposed internalization model of reflective emotion regulation argues that caregivers’ co-regulation of emotionally challenging events plays a constitutive role for the development of 4- to 6-year-olds’ reflective emotion regulation. The model specifies the gradual shift from co- to self-regulation by focusing on two important ways how caregivers structure emotionally challenging interactions: Through emotion talk, caregivers promote the development of preschoolers’ emotional awareness. Once established, they support children in establishing a repertoire of effective emotion regulation strategies and they guide preschoolers’ emerging skills to generate, evaluate, and select from alternative appraisals or behavioral responses.

description: The MIEZE (Modulation of Intensity with Zero Effort) technique is a variant of neutron resonance spin echo (NRSE), which has proven to be a unique neutron scattering technique for measuring with high energy resolution in magnetic fields. Its limitations in terms of flight path differences have already been investigated analytically for neutron beams with vanishing divergence. In the present work Monte-Carlo simulations for quasi-elastic MIEZE experiments taking into account beam divergence as well as the sample dimensions are presented. One application of the MIEZE technique could be a dedicated NRSE-MIEZE instrument at the European Spallation Source (ESS) in Sweden. The optimisation of a particular design based on Montel mirror optics with the help of Monte Carlo simulations will be discussed here in detail.

description: We investigate the light transmission through a nanoaperture in a metal film deposited on a planar metamaterial. An effect of an anomalously high light transmission through the nanoaperture is revealed, which we associate with the enhancement of the field at the interface of the planar structure "metamaterial-metal" due to the appearance of an optical Tamm state. In this structure, we also observe an "optical diode" effect: the light transmission radically changes as the direction of irradiation of the structure is reversed. Our numerical results agree well with experimental data.

Einfluss von Sekundärströmungen auf den Druckrückgewinn in Axialdiffusoren

description: Für die Auslegung von effizienten Turbinendiffusoren müssen die Abströmbedingungen der vorgeschalteten Turbine mit einbezogen werden. Dabei ist es wichtig, die sich aus der Abströmung ergebenden instationären Effekte und Sekundärströmungen zu berücksichtigen. Diese haben einen erheblichen Einfluss auf die Stabilisierung der Grenzschicht und damit auf den erzielten Druckrückgewinn im Diffusor. Um den Einfluss von Sekundärströmungen auf den Druckrückgewinn zu untersuchen, werden am Diffusorprüfstand des Instituts für Turbomaschinen und Fluid-Dynamik der Leibniz Universität Hannover unterschiedliche Abströmbedingungen aus einer Turbinenstufe nachgebildet. Dafür kommen ein turbomaschinenähnlicher Rotor mit NACA-Profilen und zwei Rotoren mit zylindrischen Speichen zum Einsatz. Durch die Variation der Drehzahl und des Massenstroms wird ein breites Spektrum an Zuströmbedingungen für den nachgeschalteten Ringdiffuusor generiert. Für den Ringdiffuusor werden zwei Geometrien mit 15 ° und 20° halbem Öffnungswinkel verwendet. Durch den Einsatz von instationär messenden dreidimensionalen Hitzdrahtsonden und instationären Druckaufnehmern im Gehäuse werden die instationären Strömungsphänomene im gesamten Ringdiffusor aufgelöst. Entscheidend für die Stabilisierung der gehäuseseitigen Grenzschicht ist der Transport von kinetischer Energie aus der Hauptströmung in die Grenzschicht. Die Strömungsbedingungen in der Nähe des Gehäuses am Diffusoreintritt haben dabei einen entscheidenden Einffluss auf die Ausprägung der gehäuseseitigen Grenzschicht. In Überlastpunkten des NACA-profilierten Rotors bilden sich an den Schaufelspitzen Wirbelstrukturen aus, die im Ringdiffusor einen Transport von energiereicher Strömung in die Grenzschicht gewährleisten und dadurch zu einem erhöhten Druckrückgewinn führen. Der Eintrag von turbulenter kinetischer Energie in der gehäusenahen Strömung im Diffusoreintritt kann isoliert für die eingesetzten Rotoren linear mit dem Druckrückgewinn im Ringdiffusor korreliert werden. Die Schubspannungen in der gehäusenahen Strömung im Diffusoreintritt werden für den 20°-Ringdiffusor über eine logarithmische Funktion mit dem erzielten Druckrückgewinn korreliert. Diese Korrelation erfolgt unabhängig vom eingesetzten Rotor und bildet damit einen Zusammenhang, der ausschließlich von den auftretenden Strömungsphänomen und nicht von der Geometrie des Rotors abhängig ist. Für alle untersuchten Betriebspunkte liegt eine anisotrope Turbulenz vor. Beim Einsatz des turbomaschinenähnlichen NACA-profilierten Rotors wird für die Betriebspunkte, die einen Druckrückgewinnkoeffizienten >0.35 erreichen, eine axialsymmetrische Turbulenz mit einer höheren Schwankungsgröße in radialer Richtung nachgewiesen.
