description: Studying the average properties of active galactic nuclei (AGN) host stellar populations is an important step in understanding the role of AGN in galaxy evolution and the processes which trigger and fuel AGN activity. Here we calculate model spectral energy distributions (SEDs) that include emission from the AGN, the host galaxy stellar population, and dust enshrouded star formation. Using the framework of cosmic X-ray background population synthesis modeling, the model AGN hosts are constrained using optical (B band) and near infrared (J band, 3.6 um, 5.7 um, 8.0 um, and 24 um) luminosity functions and number counts. It is found that at z < 1, type 1 and type 2 AGN hosts have similar stellar populations, in agreement with the orientation based unified model and indicative of secular evolution. At z > 1, type 2 AGN hosts are intrinsically different from type 1 AGN hosts, suggesting that the simple orientation based unified model does not hold at z > 1. Also, it is found that if Compton thick (CT) AGN evolve like less obscured type 2 AGN, then, on average, CT AGN hosts are similar to type 2 AGN hosts; however, if CT obscuration is connected to an evolutionary stage of black hole growth, then CT AGN hosts will also be in specific evolutionary stages. Multi-wavelength selection criteria of CT AGN are discussed.

description: Im vorliegenden Artikel werden theoretische und methodische Ansätze zur interkulturellen Kompetenzvermittlung im Rahmen der Integrationsförderung von eingewanderten Lernern konzipiert. Dazu werden wichtige Begriffe, auf denen der Lernprozess beruhen muss (“Integration“, “Kultur, Kommunikation, Sprache“; “Interkulturelle Kompetenz“, “Interkulturelle Kompetenzvermittlung“) erläutert und analysiert. Auf der Grundlage der konzipierten methodischen Ansätze der interkulturellen Kompetenzvermittlung werden Ziele, Lerninhalt und -methoden sowie entsprechende didaktische Lernmittel bestimmt. Die konzipierten methodischen Ansätze der interkulturellen Kompetenzvermittlung sind auf die Erzielung folgender Resultate bei Lernenden gerichtet: Aneignung von Kenntnissen über eine fremde Kultur und ihre Besonderheiten, Normen und Prinzipien des kommunikativen Verhaltens in einem anderen soziokulturellen Umfeld und angemessene Verhaltensmuster; Erwerb von Fertigkeiten und Fähigkeiten zur effektiven Kommunikation und zum Zusammenwirken in verschiedenen interkulturellen Situationen; Förderung von für eine produktive Kommunikation wünschenswerten persönlichen Eigenschaften wie unvoreingenommene Wahrnehmung, Verständnis, Akzeptanz der eigenen Gefühle, Empathie, was den Begriff “interkulturelle Toleranz“ kennzeichnet. Für die interkulturelle Kompetenzvermittlung werden Ziele, Lerninhalt und -methoden sowie entsprechende didaktische Lernmittel bestimmt. Da die interkulturelle Kompetenz vor allem als Aspekt der Handlungskompetenz des Menschen verstanden wird, wird der Lernprozess in Form eines Trainings mit geeigneten Lernmethoden und Aktions- und Sozialformen gestaltet. Im Rahmen des durchgeführten Trainings umfasst jeder Unterricht vier Phasen: Orientierung, eine kognitive Phase, Transformation, Reflexion. In der Orientierungsphase werden die Studierenden auf das entsprechende Thema sensibilisiert. Das Ziel der kognitiven Phase ist es, neues Wissen zu einem Thema der interkulturellen Kommunikation zu vermitteln. Die Transformationsphase fördert beim Lernenden die Handlungskompetenz. Das Ziel der Reflexionsphase ist es, die Studierenden zur Selbstreflexion und Selbstevaluation ihrer Leistungen und zur Reflexion persönlicher Erfahrungen anzuregen. Also die interkulturelle Kompetenzvermittlung ist ein zielgerichteter pädagogischer Lernprozess, der auf den wissenschaftlichen Grundlagen konzipiert wird und die Bestimmung von Zielen, Lerninhalten, Lernmethoden und Organisationsformen der Lerntätigkeit aller Teilnehmenden voraussetzt.

description: Epitaxially grown, high quality semiconductor InSb nanowires are emerging material systems for the development of high performance nanoelectronics and quantum information processing and communication devices, and for the studies of new physical phenomena in solid state systems. Here, we report on measurements of a superconductor-normal conductor-superconductor junction device fabricated from an InSb nanowire with aluminum based superconducting contacts. The measurements show a proximity induced supercurrent flowing through the InSb nanowire segment, with a critical current tunable by a gate, in the current bias configuration and multiple Andreev reflection characteristics in the voltage bias configuration. The temperature dependence and the magnetic field dependence of the critical current and the multiple Andreev reflection characteristics of the junction are also studied. Furthermore, we extract the excess current from the measurements and study its temperature and magnetic field dependences. The successful observation of the superconductivity in the InSb nanowire based Josephson junction device indicates that InSb nanowires provide an excellent material system for creating and observing novel physical phenomena such as Majorana fermions in solid state systems.

description: Concrete structures are increasingly becoming exposed to organic acid attack conditions, such as those found in agriculture and food-related industries. This paper aims to experimentally verify the thermodynamic modeling of cement pastes under acetic acid attack. For this, a modeling approach implemented in IPHREEQC via Matlab is described, and results are compared with measured pH and compositions of equilibrated solutions (MP-AES) as well as unreacted/precipitated solids (XRF, XRD and STA) for a wide range of acid concentrations. The 11% replacement of cement by silica fume (SF) led to a 60 or 70% reduction (measured or modeled, respectively) of Portlandite content in the hardened cement paste due to the pozzolanic reaction resulting in higher content of CSH phases, which has effects on the progression of dissolution processes and a resulting pH with increased acid concentrations. Considering that no fitting parameter was used, the model predictions showed good agreement with measured values of pH, dissolved ion concentrations and composition of the remaining (degraded) solids overall. The discrepancies here were more pronounced at very high acid concentrations (equilibrium pH < ~4), i.e., after the full dissolution of hydrate phases due to limitations in the model used to describe Al-, Si- and Fe-gel phases and/or identified experimental challenges in precipitation of calcium and aluminum acetate hydrates.

description: The response of Dirac fermions to a Coulomb potential is predicted to differ significantly from the behavior of non-relativistic electrons seen in traditional atomic and impurity systems. Surprisingly, many key theoretical predictions for this ultra-relativistic regime have yet to be tested in a laboratory. Graphene, a 2D material in which electrons behave like massless Dirac fermions, provides a unique opportunity to experimentally test such predictions. The response of Dirac fermions to a Coulomb potential in graphene is central to a wide range of electronic phenomena and can serve as a sensitive probe of graphene's intrinsic dielectric constant, the primary factor determining the strength of electron-electron interactions in this material. Here we present a direct measurement of the nanoscale response of Dirac fermions to a single Coulomb potential placed on a gated graphene device. Scanning tunneling microscopy and spectroscopy were used to fabricate tunable charge impurities on graphene and to measure how they are screened by Dirac fermions for a Q = +1|e| impurity charge state. Electron-like and hole-like Dirac fermions were observed to respond very differently to tunable Coulomb potentials. Comparison of this electron-hole asymmetry to theoretical simulations has allowed us to test basic predictions for the behavior of Dirac fermions near a Coulomb potential and to extract the intrinsic dielectric constant of graphene: ε_g= 3.0 \pm 1.0. This small value of ε_g indicates that microscopic electron-electron interactions can contribute significantly to graphene properties.

description: The n-3H and p-3He elastic phase-shifts below the trinucleon disintegration thresholds are calculated by solving the 4-nucleon problem with three different realistic nucleon-nucleon interactions (the I-N3LO model by Entem and Machleidt, the Argonne v18 potential model, and a low-k model derived from the CD-Bonn potential). Three different methods -- Alt, Grassberger and Sandhas, Hyperspherical Harmonics, and Faddeev-Yakubovsky -- have been used and their respective results are compared. For both n-3H and p-3He we observe a rather good agreement between the three different theoretical methods. We also compare the theoretical predictions with the available experimental data, confirming the large underprediction of the p-3He analyzing power.

description: The material of the article deals with one of the leading problems of the research project, which is dedicated to studying the experience of socialisation of Ukrainian refugees in European countries. The study analyses experience of a Ukrainian asylum seeker in Germany, one of the leaders of European countries, that is concerned with the problems of displaced people, provides social protection and humanitarian assistance within the framework of various government programmes. The study is based on the premise that Ukrainian refugees are experts in their own experience of socialisation / social adaptation in a foreign country, and that communication skills are an element of the psychological stability of Ukrainians. Evaluation of the respondents' life experience was carried out by qualitative and quantitative methods. The total sample of the study is 78 people (59 female and 19 male) from 35 families living in Wiesbaden, Russelsheim on the Main, Taunusstein (Germany). We compared effects of stress resistance in each of the groups by the following points: male, female, children; at the time of arrival and long stay in a foreign country; adaptability of children to conditions from these families. The results show that men and women who have leading roles in their families face more stress, and possess resistance skills relatively better than those who have ... The indicator of perception of the social situation by refugees differs, – between those who have just arrived and those who have already had social experience of living in new conditions for some time.

description: We present distance measurement of the semiregular variable RX Bootis (RX Boo) with its annual parallax. Using the unique dual-beam system of the VLBI Exploration of Radio Astrometry (VERA) telescope, we conducted astrometric observations of a water maser spot accompanying RX Boo referred to the quasar J1419+2706 separated by 1.69 degrees from RX Boo. We have measured the annual parallax of RX Boo to be 7.31 +/- 0.50 mas, corresponding to a distance of 136 +10/-9 pc, from the one-year monitoring observation data of one maser spot at VLSR = 3.2 km/s. The distance itself is consistent with the one obtained with Hipparcos. The distance uncertainty is reduced by a factor of two, allowing us to determine the stellar properties more accurately. Using our distance, we discuss the location of RX Boo in various sequences of Period-Luminosity (PL) relations. We found RX Boo is located in the Mira sequence of PL relation. In addition, we calculated the radius of photosphere and the mass limitation of RX Boo and discussed its evolutionary status.

description: We investigate the nature of the superfluid-insulator quantum phase transition driven by disorder for non-interacting ultracold atoms on one-dimensional lattices. We consider two different cases: Anderson-type disorder, with local energies randomly distributed, and pseudo-disorder due to a potential incommensurate with the lattice, which is usually called the Aubry-André model. A scaling analysis of numerical data for the superfluid fraction for different lattice sizes allows us to determine quantum critical exponents characterizing the disorder-driven superfluid-insulator transition. We also briefly discuss the effect of interactions close to the non-interacting quantum critical point of the Aubry-André model.

description: Energy accessibility, reliability and availability are key components of improved quality of life and human development in all spheres. As the United Nations’ SDG 7 calls for access to electricity for all by 2030, Africa still has a wide gap to fill as the statistics show that 85% of the population that will not have access to electricity is in Africa. As the world tries to wean itself off non-renewable energy and transition to green through use of renewable energy sources, hydropower energy remains at the heart of Africa for this venture. With majority of the rural population in Africa lacking electricity, there is need for a low-tech system that utilizes river flow to generate just enough energy for normal operation in these regions. Micro-hydrokinetic river turbine technology (µ-HRT), which offers less intermittency, can potentially contribute to sustainably electrifying Africa rural areas. The technology has been adopted by few countries worldwide, with limited comprehensive study in Africa even though the technology seems viable for use in African rivers. This paper reviewed the status of the µ-HRT applications in Africa and some of the barriers to its development. The study found out that the technology has not been vastly developed in Africa. Despite numerous barriers, the technology is simply a low-tech technology that requires the use of local resources and capacity building for its sustainability in terms of construction, operation and maintenance requirements. It is therefore recommended that R&D and field trials be conducted for its possible adoption.

description: The thermoelectric transport properties of $\text{Bi}_2\text{Te}_3/\text{Sb}_2\text{Te}_3$superlattices are analyzed on the basis of first-principles calculations and semi-classical Boltzmann theory. The anisotropy of the thermoelectric transport under electron and hole-doping was studied in detail for different superlattice periods at changing temperature and charge carrier concentrations. A clear preference for thermoelectric transport under hole-doping, as well as for the in-plane transport direction was found for all superlattice periods. At hole-doping the electrical transport anisotropies remain bulk-like for all investigated systems, while under electron-doping quantum confinement leads to strong suppression of the cross-plane thermoelectric transport at several superlattice periods. In addition, insights on the Lorenz function, the electronic contribution to the thermal conductivity and the resulting figure of merit are given.

description: Motivated by recent experimental results, we study the effect of size reduction on half-doped manganite, La$_{0.5}$Ca$_{0.5}$MnO$_3$, using the combination of density functional theory (DFT) and dynamical mean field theory (DMFT). We find that upon size reduction, the charge-ordered antiferromagnetic phase, observed in bulk, to be destabilized, giving rise to the stability of a ferromagnetic metallic state. Our theoretical results, carried out on defect-free nanocluster in isolation, establish the structural changes that follow upon size reduction to be responsible for this. Our study further points out the effect of size reduction to be distinctively different from application of hydrostatic pressure. Interestingly, our DFT+DMFT study, additionally, reports the correlation-driven stability of charge-orbitally ordered state in bulk La$_{0.5}$Ca$_{0.5}$MnO$_3$, even in absence of long range magnetic order.

description: This study examines the impact of corruption on credit risk in Southeast Asian commercial banks by using machine learning models to predict non-performing loans (NPLs) based on the Corruption Perception Index (CPI). Analyzing data from 70 banks over a decade, it employs Decision Tree, Random Forest, Gradient Boosted Trees, and XGBoost models, evaluated using R², RMSE, and MAE. Findings indicate that ensemble methods, particularly XGBoost, outperform simpler models in predicting NPLs influenced by corruption. Results confirm that corruption significantly increases NPLs, weakening banks’ lending capacity and financial stability. By addressing limitations of traditional risk assessment methods, this study highlights machine learning’s effectiveness in integrating corruption indices for better credit risk management. The insights benefit investors, bank managers, and policymakers, emphasizing the need for anti-corruption measures and advanced predictive models to mitigate financial risks in the region.

description: The issue of Critical Raw Materials (CRMs) and potential interruptions to their supply and availability due to concerns such as shortages, trade restrictions or geopolitical considerations are topics that are relatively unknown to the general public. Education and the dissemination of this information amongst the general public has been promoted as a key factor in addressing this and enabling the transition towards a circular economy. By and large, the general public are unaware of the existence of CRMs, their importance in our world and how they contributes to this issue. Educating people about these issues is one way to redress this shortcoming in modern society. Electronic repair events, repair cafés and repair workshops have been gaining momentum at national and international level as a means of addressing the perceived waste inherent in the current linear consumption model. Repair events have existed for quite some time throughout Europe and around the world. When considered in conjunction with the problem of CRM education, they provide aninnovative and novel platform for the dissemination of knowledge and the education of the general public on CRM issues. However, at present electronic repair events and workshops lack the capacity or knowledgebase to educate the public about complex issues such as CRMs and their importance. Raw Engagement for Electronics Repair (REFER) is a KIC Raw Materials project that seeks to address this gap and use platforms such as electronic repair workshops to educate the general public and the wider society about CRMs through engagement in such events. The project will host 60 Restarter Party events across 6 different E.U. member states, engaging with up to 6,000 members of the general public directly on matters of repair, re-use and CRM importance. A set of educational resources has been developed to support these engagements and related referrals through social media, word-of-mouth and website interactions.

description: Water vapor plays an important role in many aspects of the climate system, by affecting radiation, cloud formation, atmospheric chemistry and dynamics. Even the low stratospheric water vapor content provides an important climate feedback, but current climate models show a substantial moist bias in the lowermost stratosphere. Here we report crucial sensitivity of the atmospheric circulation in the stratosphere and troposphere to the abundance of water vapor in the lowermost stratosphere. We show from a mechanistic climate model experiment and inter-model variability that lowermost stratospheric water vapor decreases local temperatures, and thereby causes an upward and poleward shift of subtropical jets, a strengthening of the stratospheric circulation, a poleward shift of the tropospheric eddy-driven jet and regional climate impacts. The mechanistic model experiment in combination with atmospheric observations further shows that the prevailing moist bias in current models is likely caused by the transport scheme, and can be alleviated by employing a less diffusive Lagrangian scheme. The related effects on atmospheric circulation are of similar magnitude as climate change effects. Hence, lowermost stratospheric water vapor exerts a first order effect on atmospheric circulation and improving its representation in models offers promising prospects for future research.

Reduced remanence () is higher than 0.7. High-temperature magnetic measurements show very good stability above 300 C with coercive field as high as 5.2 kOe at 330 C. For annealed Sm(CobalFe0 3Zr0 02B0 04)7 5, very good loop squareness and high maximum energy product of 10.7 MGOe have been obtained. Increasing Zr content results in less uniform microstructure of annealed ribbons.

description: Highly charged heavy ions at rest offer a wide spectrum of precision measurements. The GSI Helmholtzzentrum für Schwerionenforschung GmbH is able to deliver ions up to U92+. As the production of these heavy, highly charged ions requires high kinetic energies, it is necessary to decelerate these ions for ultimate precision. The broad energy distribution, which results from the deceleration in the HITRAP linear decelerator, needs to be reduced to allow for further transportation and experiments. The HITRAP cooling trap is designed to cool, i.e., reduce, this energy spread by utilizing electron cooling. The commissioning of this trap is done with Ar16+-ions from a local EBIT ion source. By analyzing the signal of stored ions after ejection, properties such as ion lifetime, charge exchange, and ion motions can be observed. Here, we provide an overview of the recent results of the commissioning process and discuss future experiments.

Reframing pedagogic practices using a social practice perspective to explain and inform change in the Irish Technological Higher Education Sector
Creators: name: Harding, Nuala
Publisher: name: Lancaster University
Year: 2022

description: This practice-focused ethnographic study was conducted in the context of the Irish technological higher education sector to elucidate and enhance pedagogic practices during a time of radical change with the establishment of Technological Universities. Underpinned by Social Practice Theory (SPT), the Teaching and Learning Regime (TLR) theoretical framework was trialled to reframe the pedagogic practices of lecturers within the sector. Rather than deploying a narrow focus of evaluating the impact of professional development using a practice perspective, this study explored broader questions regarding change to pedagogic practices, including the material environment and contextual factors which condition their adoption. The ontological perspective of Critical Realism (CR) informed the design of a theory-driven methodological approach to research design and analysis of data. A process for the systematic mapping of data to the TLR theoretical framework was devised. Nineteen postgraduate diploma graduates from four geographically dispersed Institutes of Technology (IoTs) participated in this research study. The postgraduate programme was designed to develop pedagogic practices and address sectoral requirements. An essential aspect of the research design was the requirement for research participants to teach for one year after graduation. This enabled the examination of pedagogic practices and conditioners of change within the workgroup. To avoid reliance on self-reporting and informed by the SPT elements of materials, competences and meanings, the variety of data collection methods included semi-structured and focus group interviews, classroom observations and digital artefacts to represent teaching. New perspectives of pedagogic practices emerged with substantial evidence of early-career transmission-focused practices changing to contemporary approaches, thereby impacting student experiences. The TLR transpired to be a comprehensive theory for understanding, explaining, and implementing change in higher education. The study will inform the design and evaluation of professional development and change initiatives at the micro-, meso- and macro-level in the Irish technological higher education sector.

description: We coincidently measure the molecular frame photoelectron angular distribution and the ion sum-momentum distribution of single and double ionization of CO molecules by using circularly and elliptically polarized femtosecond laser pulses, respectively. The orientation dependent ionization rates for various kinetic energy releases allow us to individually identify the ionizations of multiple orbitals, ranging from the highest occupied to the next two lower-lying molecular orbitals for various channels observed in our experiments. Not only the emission of a single electron, but also the sequential tunneling dynamics of two electrons from multiple orbitals are traced step by step. Our results confirm that the shape of the ionizing orbitals determine the strong laser field tunneling ionization in the CO molecule, whereas the linear Stark effect plays a minor role.

1ES 0229+200: An extreme blazar with a very high minimum Lorentz factor

description: The blazar 1ES 0229+200 is a high frequency peaked BL Lac object with a hard TeV spectrum extending to 10 TeV. Its unusual spectral characteristics make it a frequently used probe for intergalactic radiation and magnetic fields. With new, simultaneous observations in the optical, ultraviolet (UV) and X-rays, the synchrotron emission is probed in great detail. The X-ray emission varies by a factor of ~2 in 2009, while being rather stable in 2010. The X-ray spectrum is very hard (Γ~ 1.8) and it shows an indication of excess absorption above the Galactic value. The X-ray emission is detected up to ~100 keV without any significant cut-off, thus 1ES 0229+200 belongs to the class of extreme blazars. The simultaneous measured, host galaxy- and extinction-corrected optical and UV fluxes illustrate that the cut-off of the low energy part of the synchrotron emission is located in the UV regime. The minimum energy of the electron distribution has to be rather high to account for this cut-off. This implies that there is a narrow-band energy distribution function of radiating electrons, which is responsible for the unusually hard TeV spectrum. Other extreme blazars have similar synchrotron peak frequencies but much softer TeV spectra, hence 1ES 0229+200 has one of the highest inverse Compton (IC) peak frequency and the narrowest electron distribution among the extreme blazars known to date.

description: This document, a public report on the computational approaches and models, is a deliverable of the LICROX Project, which is funded by the European Union’s H2020 Programme under Grant Agreement No. 951843. It aims to expose in a detailed manner all the theoretical models used to study the light propagation inside the tandem photoelectrochemical cells, and in particular to determine the external quantum efficiency and short circuit currents of the different materials. In addition, it also presents some strategies applied to optimize the performance of the given tandem devices, both by introducing 1-dimensional nanophotonic structures and/or by using 3-dimensional scattering centers. Some main computational results are also presented and indicate that in both cases a considerable increase of the BiVO4 short circuit current can be achieved in relation to a bare flat photoanode due to a better light trapping and distribution alongside the device.
Arquitectura Semântica Para A Integração De Sistemas No Domínio Do Turismo

description: The tourism industry is characterized by its heterogeneity and by a high volume of online transactions. Small tourist operators develop their own booking systems more and more to avoid paying commissions to the big tourist information system owners. Due to this fact, many new sources of tourist information are appearing in the Internet and the escalation of these new sources makes the planning of holidays more complex to the tourists. The development of a system that enables the integration of different sources becomes an urgent necessity when it comes to help tourists plan their holidays and at the same time gives means to the tourist operators to develop new marketing strategies. One of them is most certainly the development of Dynamic Packaging. Dynamic Packaging allows the tourist or the agent to freely choose the products that will compose a holiday package. At the same time the tourist operators will be able to set business rules that will be dynamically applied when the packages are being created. SEED architecture describes the implementation of an integration system and it also intents to be a base to develop a system that will support Dynamic Packaging. The integration of different sources of information can be made by using technologies related to the Semantic Web. The implementation of Dynamic Packaging is supported by reasoning engines that allow the definition and interpretation of semantic rules.
Excited state g-functions from the Truncated Conformal Space

description: In this paper we consider excited state g-functions, that is, overlaps between boundary states and excited states in boundary conformal field theory. We find a new method to calculate these overlaps numerically using a variation of the truncated conformal space approach. We apply this method to the Lee-Yang model for which the unique boundary perturbation is integrable and for which the TBA system describing the boundary overlaps is known. Using the truncated conformal space approach we obtain numerical results for the ground state and the first three excited states which are in excellent agreement with the TBA results. As a special case we can calculate the standard g-function which is the overlap with the ground state and find that our new method is considerably more accurate than the original method employed by Dorey et al.

description: Archaeologists have not generally utilized faunal remins resulting from subsistence activities to their best advantage in interpreting past cultural systems. This is mainly due to the absence of an objective system of analysis whereby the relevant information can be elicited. The present study examines the major factors acting upon the faunal remains in archaeological sites and postulates the configurations these remains would take when subjected to alteration by these factors in their various states. A methodology is proposed that serves to isolate each variable for separate analysis so that its impact upon the faunal material can be individually assessed. The validity of these techniques of analysis is tested by use of a control .archaeological sample where the states of the variables are largely known due to the presence of documentary records. The archaeological sites are three Metis settlements from the Canadian Plains. The applicability of the techniques is generally corroborated. The study indicates that states of variables pertaining to the logistics of procurement, to the procedures employed for processing the subsistence resource, and to many of the aspects of the social structure of the community under consideration, can be deduced from patterning in faunal remains.
