description: We introduce a classification of simple, regular, closed symmetric operators with deficiency indices (1,1) according to a geometric criterion that extends the classical notions of entire operators and entire operators in the generalized sense due to M. G. Krein. We show that these classes of operators have several distinctive properties, some of them related to the spectra of their canonical selfadjoint extensions. In particular, we provide necessary and sufficient conditions on the spectra of two canonical selfadjoint extensions of an operator for it to belong to one of our classes. Our discussion is based on some recent results in the theory of de Branges spaces.

description: Numerous diffuse sources contribute in addition to industrial plants to atmospheric particulate matter (PM) concentrations causing concern regarding potential health effects and environmental impacts. Routine monitoring focuses on PM mass and determination of the total concentrations for selected elements. However, assessment of the (eco-)toxicological potential and the spatial distribution as well as the interaction in the environment requires suitable characterisation of the elemental speciation and mobility. Classical off-line sequential extraction techniques have been explored for this purpose but require high effort and were of limited suitability especially for low particle mass sampled on filters. A novel online sequential extraction (OSE) technique was recently developed using low amounts of model dust samples with transient elemental monitoring by inductively coupled plasma mass spectrometry (ICP-MS) to overcome the challenges. However, the application of this method to PM samples was not reported until now. In the current study, the OSE was adapted for application to punches of PM2.5 filter samples to achieve elemental fractionation with minimum manual input, low relative standard deviations and reduced risk of contamination or loss of residual sample material during solvent changes. Four samples from China and seven samples from Germany were exemplary investigated to identify regional and temporal changes in elemental fractionation and to highlight the potential of the OSE method for filter samples. Normalisation of the data as percentage of the aqua regia leachable fraction for each element demonstrated clear differences between the Chinese and the German samples. In particular, fireworks affected samples showed a unique characteristic mobility pattern. In addition, normalisation to the aqua regia leachable Mn content was performed to highlight the combination of the elemental fractionation pattern and the relative abundance between the various investigated samples. Thereby, a major improvement in the classification of the PM samples was achieved. Principal component analysis visualises the observed differences in 2-D plots with clusters of different regional and also partly different temporal samples. The obtained results indicate the potential of OSE for an improved understanding of chemical element patterns of PM samples in future studies.

description: In light of the discovery of a Higgs-like particle at the LHC, we revisit the status of the precision electroweak data, focusing on two discrepant observables: 1) the long-standing 2.4 sigma deviation in the forward-backward asymmetry of the bottom quark A_{FB}^b, and 2) the 2.3 sigma deviation in R_b, the ratio of the Z \rightarrow b \bar b partial width to the inclusive hadronic width, which is now in tension after a recent calculation including new two-loop electroweak corrections. We consider possible resolutions of these discrepancies. Taking the data at face value, the most compelling scenario is that new physics directly affects A_{FB}^b and R_b, bringing the prediction into accord with the measured values. We propose a modified `Beautiful Mirrors' scenario which contains new vector-like quarks that mix with the b quark, modifying the Z b\bar b vertex and thus correcting A_{FB}^b and R_b. We show that this scenario can lead to modifications to the production rates of the Higgs boson in certain channels, and in particular a sizable enhancement in the diphoton channel. We also describe additional collider tests of this scenario.

description: Random bond disorder in antiferromagnetic spin-1/2 Heisenberg ladders is investigated using the Stochastic Series Expansion Quantum Monte Carlo method. We find that the effects of individual bond impurities vary strongly, depending on their position on legs and rungs. We initially focus on how the distribution of local bond energies depends on the impurity concentration. Then we study how the phase diagram of even-leg ladders is affected by random bond doping. We observe Bose glass phases in two regimes ($h' < h \lesssim h_{c1}$ and $h" < h

description: To extract vanadium (V) ions from the ferruginous siltstone at Abu Zeneima in Southwestern Sinai, Egypt, a synthesized chelating N-phenyl acetyl-N-naphthyl hydroxyl amine (PANHA), was used. Complete characterization was carried out successfully to elucidate the structure using several techniques such as FT-IR,1H-NMR, 13C-NMR, GC-MS and TGA analysis performances. Improved experimental measurements, such as pH, shaking time, initial concentration of V(V), PANHA dosage, temp., and stripping agents, have been achieved with the solvent extraction technique. At 25 ℃ and 0.015 mole per liter through 30 minutes, PANHA/CHCl3 has an extreme retention potential of 50 mg per gram at 25 ℃ at pH 1.5 at 1:1 aqueous to organic phase ratio. The linear regression analysis, consisting of a log D track versus pH, shows a straight line with a slope of 0.859, indicates that a mole of H+ was released during the extraction. The stability constant (β), of PANHA-V(V) complex was calculated from the intersection (log β=1.7958), and it was found to equal 63.1. The stoichiometry mechanism among a chelating ligand of PANHA and V(V) indicates a roughly linear correlation with slope of 0.882 which explains that one mole of PANHA chelating ligand can react with one mole of V (V). According to the kinetic and thermodynamic interpretations, the pseudo-second order kinetic model predicted the kinetics of vanadium (V) extraction, the thermodynamic factors ΔS, ΔH, and ΔG were also measured. As the temperature rises, ∆G values rise from -10.45 kJ/mol at 198 K to -2.2 kJ/mol at 353 K. Vanadium may be stripped from the loaded PANHA/CHCl3, by 0.5M NaOH with a 99% efficiency rate. To obtain a vanadium concentrate (NH4VO3, AMV) with a vanadium content of 42.6 percent and pureness of 98 percent, the enhanced variables were finally put to use.

description: The magnetic phase diagram has been mapped out via the measurements of electronic resistivity, magnetization and specific heat in the cobalt-based layered LnCo1-xFexAsO (Ln=La, Sm) compounds. The ferromagnetic (FM) transition at 63 K for LaCoAsO is rapidly suppressed upon Fe doping, and ultimately disappears around x=0.3 in the LaCo1-xFexAsO system. When La is replaced by magnetic rare earth element Sm, the 3d electrons first undergo a FM transition at Tc = 75 K, followed by an antiferromagnetic (AFM) transition at a lower temperature TN1 = 45 K. With partial Fe doping on the Co site, both FM (Tc) and AFM (TN1) transition temperatures are significantly suppressed, and finally approach zero kelvin at x = 0.3 and 0.2, respectively. Meanwhile, a third magnetic transition at TN2 = 5.6 K for SmCoAsO, associated with the AFM order of the Sm3+ 4f-oments, is uncovered and TN2 is found to be almost robust against the small Fe-doping. These results suggest that the 4f electrons of Sm3+ have an important effect on the magnetic behavior of 3d electrons in the 1111 type Co-based LnCo1-xFexAsO systems. In contrast, the magnetism of the f-electrons is relatively unaffected by the variation of the 3d electrons. The rich magnetic phase diagram in the Co-rich side of the LnCo1-xFexAsO system, therefore, is established.

description: Die Beschäftigung mit Postkolonialismus hat in den letzten Jahren auch in Österreich zugenommen. Dennoch gibt es nach wie vor Forschungslücken in Bezug auf postkolonialer Theorie in der Pädagogik und Didaktik. Auch im Bereich der österreichischen Schulbuchforschung gibt es Aufholbedarf. Das Ziel dieser Arbeit ist, herauszufinden inwiefern in Ethikschulbüchern Wissensinhalte durch postkoloniale Theorie vermittelt werden. Dazu werden die Theorien Othering, Orientalismus, Rassismus, Eurozentrismus, Strategischer Essentialismus und Repräsentation verwendet, um zu analysieren, welche dieser Aspekte in den Ethikschulbüchern vorhanden sind. Das Material besteht aus vier verschiedenen Ethikschulbücher, die seit 2021 verfasst wurden, auf Grund des neu eingeführten und verpflichtenden Schulfaches Ethik. Die Bücher sollen mit Hilfe der Schulbuchanalyse nach Markom & Weinhäupl (2007), sowie der kolonialen Diskursanalyse (Stewart, 2022) untersucht werden. Obwohl in allen vier Schulbüchern gut gelungene Ansätze gefunden werden konnten, gibt es dennoch auch Verbesserungspotenzial, vor allem im Hinblick auf das Miteinbeziehen von außereuropäischen Ansätzen und Philosoph*innen.

description: Crop residue ashes exhibit significant capacity to adsorb pesticides and affect their adsorption behaviour in soils. The present study evaluated the effect of sugarcane trash ash (STA), the third most important crop whose residues are burnt in fields in India, on atrazine and fipronil leaching behaviour in three sugarcane growing soils. The STA reduced downward mobility of atrazine in soils but, effect varied with the soil type. No atrazine residues were detected in the leachate. Atrazine was fairly mobile in the sandy loam soil than the loam and the clay loam soils and increasing leaching intensity from 64 to 128 mm, further increased herbicide’s downward mobility. Significant atrazine degradation was observed during leaching process and 38–43, 1.5–12.5 and 27–41% of column applied atrazine was degraded in the silty clay loam, the sandy clay loam and the loam soils, respectively. Higher atrazine degradation in the clay loam and the loam soils was attributed to slow water percolation rate and longer time to complete leaching process. Hydroxyatrazine, deethylatrazine and deisopropylatrazine metabolites of atrazine were detected in the soil samples, but their amounts varied in different treatments. Compared to atrazine, fipronil was highly retained in the surface layer (0–5 cm) in the control and STA-mixed soil columns and no fipronil was detected in the leachate. Trash burning is a regular practice; therefore, continuous mixing of STA in soils can reduce leaching of mobile pesticides applied in sugarcane crop. This study has implications in identifying the role of crop residue burning on fate of pesticides applied in soils.

description: We report the first experimental demonstration of recently proposed energy-efficient single flux quantum logic, eSFQ. This logic can represent the next generation of RSFQ logic eliminating dominant static power dissipation associated with a dc bias current distribution and providing over two orders of magnitude efficiency improvement over conventional RSFQ logic. We further demonstrate that the introduction of passive phase shifters allows the reduction of dynamic power dissipation by about 20%, reaching ~0.8 aJ per bit operation. Two types of demonstration eSFQ circuits, shift registers and demultiplexers (deserializers), were implemented using the standard HYPRES 4.5 kA/cm2 fabrication process. In this paper, we present eSFQ circuit design and demonstrate the viability and performance metrics of eSFQ circuits through simulations and experimental testing.

description: Ciprofloxacin (Cip), a fluoroquinolone antibiotic, was determined by linear sweep adsorptive stripping voltammetric method using multilayer reduced graphene oxide electrode (m-rGO). The m-rGO electrode was fabricated directly, simply and promptly from graphite platform by potentiostatic technique without further modification. The produced electrode exhibited excellent performance for ciprofloxacin (Cip) determination with a much higher signal of Cip than that on the initial graphite electrode (13.4 times). This dominance of the m-rGO electrode resulted from the large electrochemically active surface area, electrochemical catalysis, suitable functional groups on the electrode surface. Experimental conditions such as the electrode fabrication time, the supporting solution, and accumulation time were optimised to obtain the Cip highest signal. A Cip analytical method established under the optimal conditions had a good linear relationship between the Cip signal with its concentration range from 0.5 to 20 µM (R2 = 0.9953). The method showed a low detection limit (LOD = 0.078 µM), satisfactory reproducibility (RSD = 1.50%), and high accuracy. Cip concentration in a spiked lake water sample determined by the proposed method with acceptable precision (RSD = 5.59%) and trueness (recovery = 94.2–106.3%) was comparable with LC-MS/MS method.

description: The Encke Gap is a 320-km-wide opening in Saturn's outer A ring that contains the orbit of the small moon Pan and an array of dusty features composed of particles less than 100 microns across. In particular, there are three narrow ringlets in this region that are not longitudinally homogeneous, but instead contain series of bright clumps. Using images obtained by the Cassini spacecraft, we track the motions of these clumps and demonstrate that they do not follow the predicted trajectories of isolated ring particles moving under the influence of Saturn's and Pan's gravitational fields. We also examine the orbital properties of these ringlets by comparing images taken at different longitudes and times. We find evidence that the orbits of these particles have forced eccentricities induced by solar radiation pressure. In addition, the mean radial positions of the particles in these ringlets appear to vary with local co-rotating longitude, perhaps due to the combined action of drag forces, gravitational perturbations from Pan, and collisions among the ring particles. The dynamics of the dust within this gap therefore appears to be much more complex than previously appreciated.

description: In the present study, an agro-waste, almond shell was derived as activated carbon. Based on chemical oxygen demand (COD) removal of leachate, the optimised conditions of activated carbon were obtained and loaded with TiO2 nanoparticles. Brunauer Emmett Teller analysis technique is used to probe the textural properties through the specific surface area. The specific surface area of the TiO2 nanoparticle loaded activated carbon (TiO2@ASAc-7) and efficiently activated carbon (ASAc-7) were 153.3 m2/g and 54.7 m2/g. A band at 536 cm−1 in FTIR of TiO2@ASAc-7 composite demonstrates the spreading of vibrational modes of TiO2 in 4AS material. SEM-EDX shows the elemental peaks of carbon, oxygen and Ti nanoparticles along with atomic percentages of C 70.1, O 22.61, and Ti 7.29. The optimum values of pH 5.5, dose 1.75 g/50 mL, time 160 minutes and temperature 30°C were observed at maximum COD removal of 78.6%. The adsorption isotherm records were appropriately fitted to Freundlich, Hill, Khan, Redlich–Peterson, Toth, and Koble–Corrigan. The correlation coefficient (R2 = 0.9707) and a comparatively low value of the root mean square error (RMSE = 3.97) demonstrates that the adsorption technique adapted a pseudo-second-order model. Negative values of ΔG0 signify that COD removal by TiO2@ASAc-7 was spontaneous and positive values of the enthalpy change (∆H° = 37.816 kJmol−1) indicate that the process was endothermic in nature. To optimise the COD removal efficiency from the leachate sample, a central composite design for a subset of the RSM was also performed.

description: TThere are two temporal delay effects used to describe the reoccurrence of day events in dreams. The day-residue effect is the reflection of events in dreams 1-2 nights after its occurrence and has been observed in typical and unusual day events. The dream-lag effect is the re-surfacing of daily events approximately a week after and more likely to occur when personally significant events are encountered. Further, degree of emotional intensity affects likelihood of day incorporation. The current study explores the temporal pattern of incorporation of emotionally salient day events. A sample of undergraduate psychology students (N = 45) completed a daily journal of events containing emotional importance. Nightly dream journals were also maintained for one week and were required to include as much detail as possible. Independent judges rated the number of correspondences between day events and the subsequent 7 dreams. Analysis revealed a main effect of day, main effect of emotion; negative emotions (p < 0.05) and neutral items (p < 0.01) were much more likely to be incorporated in dreams than positive emotions. In addition, there were significantly more incorporations on day 1 versus day 5 (p < 0.05) and day 7 (p < 0.05) for both negative and neutral correspondences. Overall, correspondences indicated a day-residue effect, but no dream-lag effect.

description: Prometheus stahl einst den Göttern das Feuer und brachte es zu den Menschen. Dafür wurde er von den Göttern bestraft, doch die Menschen zogen daraus einen großen Nutzen und mussten weder erfrieren noch verhungern. So ähnlich kann man auch die Kernenergie betrachten. Viele Wissenschafter*innen arbeiteten daran, die Energie, die bei der Kernspaltung von Uran entsteht, nutzbar zu machen, damit die Menschen daraus ihren Vorteil ziehen können. Viele von ihnen starben an der Strahlenkrankheit und, genauso wie das Feuer, lässt sich auch die Kernenergie nicht gänzlich durch Menschen steuern. Bei beiden Kräften besteht immer das Risiko eines Unfalles, der großen Schaden über die Menschen bringen könnte. In Österreich hat die Erforschung der Kernenergie eine lange Tradition, die spätestens mit der Festlegung von Wien als Sitz der IAEA (International Atomic Energy Agency) ihren Höhepunkt erlangte. In Österreich wurde mit der Gemeinschaftskernkraftwerk Tullnerfeld Ges. m. b. H (GKT) die erste Gesellschaft gegründet, die sich mit dem Bau eines österreichischen Kernkraftwerkes im Tullnerfeld in Niederösterreich befassen sollte. Die GKT wurde im Februar 1970 gegründet und eine ihrer ersten Aufgaben bestand darin, den Reaktortyp und die Produktionsfirma für diesen Reaktor auszusuchen. Ausgewählt wurde ein Siedewasserreaktor der KWU (Kraftwerk Union) und 1972 war Baubeginn. 1976 wurde der Bau mit Verspätung fertiggestellt und bis 1978 folgte die Inbetriebnahme. Das Kernkraftwerk Tullnerfeld wurde bis zur Volksabstimmung im November 1978 mit nichtnuklearem Hilfsdampf in Betrieb genommen und konnte damit fast gänzlich in Betrieb genommen werden. Es ist somit das einzige Kernkraftwerk weltweit, das komplett fertiggestellt, aber dennoch nie mit nuklearem Material bestückt wurde. Die Masterarbeit wird dieses einzigartige Kernkraftwerk und die Entscheidungen, die vor und nach der Volksabstimmung getroffen wurden, abbilden. Gleichzeitig wird an diesen Beispielen illustriert werden, dass Archive, in diesem Fall ein Wirtschaftsarchiv, für die Forschung in diesen Gebieten unerlässlich sind. Die Wichtigkeit von Wirtschaftsarchiven, auch in technischen Unternehmen, spannt in dieser Arbeit einen Bogen um die Geschichte des Kernkraftwerkes Tullnerfeld.

description: Charge and spin density waves, periodic modulations of the electron and magnetization densities, respectively, are among the most abundant and non-trivial low-temperature ordered phases in condensed matter. The ordering direction is widely believed to result from the Fermi surface topology. However, several recent studies indicate that this common view needs to be supplemented. Here, we show how an enhanced electron-lattice interaction can contribute to or even determine the selection of the ordering vector in the model charge density wave system ErTe3. Our joint experimental and theoretical study allows us to establish a relation between the selection rules of the electronic light scattering spectra and the enhanced electron-phonon coupling in the vicinity of band degeneracy points. This alternative proposal for charge density wave formation may be of general relevance for driving phase transitions into other broken-symmetry ground states, particularly in multiband systems such as the iron based superconductors.

description: We predict the enhancement of the spin-rotation coupling due to the interband mixing. The Bloch wavefunctions in the presence of mechanical rotation are constructed with the generalized crystal momentum which includes a gauge potential arising from the rotation. Using the eight- band Kane model, the renormalized spin-rotation coupling is explicitly obtained. As a result of the renormalization, the rotational Doppler shift in electron spin resonance and the mechanical torque on an electron spin will be strongly modulated.

description: Graphene is convenient material for nanomechanichal applications since high-frequency oscillations are easily accessible. In this Article, we consider graphene on a rough substrate attached to imperfections at random locations. We explore the statistics of low-lying phonon modes, which exert most influence on the conductivity of graphene. We find that the nearest neighbor spacings of low lying eigenfrequencies have the Wigner-Dyson probability distribution after averaging over the random configurations of disorder. Due to interaction of electrons with the oscillations of the membrane, an electron can be transfered to higher or lower energies, which is a manifestation of the phonon-assisted Tien-Gordon effect. The Tien-Gordon effect suppresses the conductivity of graphene. In the regime of low Fermi energies and small sizes of the sample an increase of conductivity is observed which we refer to Klein tunneling and electron-hole pair creation. Eventually, when the increase of the transmission becomes too prominent, the pair creation changes the ground state of the system, signalizing the limit of applicability of the single-particle Dirac equation used in this paper.

description: We report an experimental study of recently formulated entropic Leggett-Garg inequality (ELGI) by Usha Devi et al. (arXiv: 1208.4491v2 (2012)). This inequality places a bound on the statistical measurement outcomes of dynamical observables describing a macrorealistic system. Such a bound is not necessarily obeyed by quantum systems, and therefore provides an important way to distinguish quantumness from classical behavior. Here we study ELGI using a two-qubit nuclear magnetic resonance system. To perform the noninvasive measurements required for the ELGI study, we prepare the system qubit in a maximally mixed state as well as use the `ideal negative result measurement' procedure with the help of an ancilla qubit. The experimental results show a clear violation of ELGI by over four standard deviations. These results agree with the predictions of quantum theory. The violation of ELGI is attributed to the fact that certain joint probabilities are not legitimate in the quantum scenario, in the sense they do not reproduce all the marginal probabilities. Using a three-qubit system, we experimentally demonstrate that three-time joint probabilities do not reproduce certain two-time marginal probabilities.

description: The pollution indices of microplastic content in bottled water from South Eastern Nigeria were evaluated. Microplastic contamination factors, pollution load and risk index, polymer risk indices and estimated daily intake for adults and children were determined. Microplastic concentrations, types and shapes were assessed using scanning electron microscopy (SEM) – energy-dispersive X-ray spectroscopy (EDS). From documented literature, this is the first study on microplastics in bottled water from Africa. The microplastics were found in 92% of the samples. The four types of microplastics were polyethylene (PE), polyvinyl chloride (PVC), polyethylene terephthalate (PET) and polydimethyl siloxane (PDMS) while the dominant shapes were fragment, film and pellet/granule. Principal component analysis shows strong association of the concentration of microplastics with total solids and total suspended solids. Pollution risk indices show medium pollution risks of microplastics in bottled water. The estimated daily intake was generally low and therefore shows no risk from daily consumption but reveals a higher intake of microplastics for children than adults. The source of the MPs was attributed to leaching from the packaging material, which should be monitored by appropriate regulatory bodies.
Correlation of task-related dream content with memory performance of a film task – A pilot study

description: Dreams could reflect memory consolidation processes during sleep. The present pilot study examined whether the incorporation of a film sequence shows a relationship to task performance. Twenty-two participants (17 women, 5 men) were exposed to a late-night paradigm in which they were shown a film sequence prior to the second sleep-onset. REM dreams and morning dreams have been collected. Compared with those of a control group the incorporation of film elements in the study group dreams was only higher for morning dream reports on one of two scales. The incorporation rate in morning dreams correlated on one scale with increased memory task performance. Due to the consolidation of declarative tasks, mainly during NREM, and procedural tasks during REM sleep, dream reports should be collected in the respective sleep stage in which the learning task is consolidated.  Furthermore, tasks with high incorporation rates should be selected to show the relationship to task performance consistently.

description: We consider general 2D orbifold CFTs of the form M^N/S_N, with M a target space manifold and S_N the symmetric group, and generalize the Lunin-Mathur covering space technique in two ways. First, we consider excitations of twist operators by modes of fields that are not twisted by that operator, and show how to account for these excitations when computing correlation functions in the covering space. Second, we consider non-twist sector operators and show how to include the effects of these insertions in the covering space. We work two examples, one using a simple bosonic CFT, and one using the D1-D5 CFT at the orbifold point. We show that the resulting correlators have the correct form for a 2D CFT.

description: In this work, novel mixtures based on silicon and tin materials were synthesised via reaction of 2.407, 5.247, 7.195, or 9.59 g of tin chloride dihydrate with 6 g of sodium metasilicate pentahydrate. The samples, which were synthesised using 2.407, 5.247, 7.195, and 9.59 g, are abbreviated as T1, T2, T3, and T4, respectively. XRD confirmed that these mixtures consist of amorphous Sn/Si, sodium tin silicate, tin oxide, and sodium silicate. The average crystallite size of T1, T2, T3, and T4 samples is 5.23, 8.13, 12.26, 15.72 nm, respectively. The synthesised mixtures were used as adsorbents for the removal of methylene blue and crystal violet dyes from aqueous media. 15 min, pH 6, and 298 Kelvin are regarded as the optimum conditions for the removal of studied dyes using T1, T2, T3, and T4 samples. The adsorption process of crystal violet or methylene blue dyes was fitted well with the Langmuir equilibrium isotherm and pseudo-second-order kinetic model. The thermodynamic parameters confirmed that the removal of crystal violet and methylene blue dyes is chemical, spontaneous, and exothermic. The maximum adsorption capacity of T1, T2, T3, and T4 samples towards crystal violet dye is 34.81, 36.83, 29.46, and 11.98 mg/g, respectively. Also, the maximum adsorption capacity of T1, T2, T3, and T4 samples towards methylene blue dye is 30.13, 29.33, 17.09, and 13.43 mg/g, respectively. HCl: butanol (1:3) can efficiently desorb the dyes for three cycles of adsorption/desorption. Hence, the adsorbents can be used successfully several times for the removal of crystal violet and methylene blue dyes.

description: In this paper we establish some spectral conditions for a graph to be Hamilton-connected in terms of the spectral radius of the adjacency matrix or the signless Laplacian of the graph or its complement. For the existence of Hamiltonian paths or cycles in a graph, we also give a sufficient condition by the signless Laplacian spectral radius.

„Kommunikation ist für die Politik systemnotwendig. Politische Kommunikation legitimiert Politik. Für die Bürger ist Politik primär medienvermittelt. Die Medien sind zum Format-, Takt-, Bild und Modellgeber der Politik avanciert“ (Korte & Regge, 2016, S. 601).
Diese Äußerung verdeutlicht die Bedeutung hinsichtlich politischer Verständigung in der Gesellschaft durch die Kommunikation über Medien und gibt einen Einblick in das Zusammenspiel von medienvermittelter Politik. Die Wirklichkeit zeigt, dass im Jahr 2024 eine Informationsbeschaffung durch mediale Angebote bereits Kindern im Grundschulalter zugänglich und vertraut ist, was Chancen auf Mitbestimmung in einer vernetzten Welt schafft, jedoch auch Eltern und Angehörige vor diverse Herausforderungen stellt (vgl. Warburg, 2021, S. 8).
Hier setzt die politische Bildung an, die eng verknüpft ist mit der Vermittlung von Medienkompetenz und somit auch dem verantwortungsvollen Umgang und dem Wissen über den Einfluss politischer Kommunikation durch Massenmedien sowie dem Wissen über die Kommunikation von Nachrichten über soziale Medien (vgl. ebd., S. 41). In der KIM-Studie 2022 (Kindheit, Internet, Medien) wird allerdings darauf aufmerksam gemacht, dass dem Thema „Nachrichten“ im Schul-Unterricht kaum eine Bedeutung zukommt (vgl. ebd., S. 48). Aus diesem Grund soll die vorliegende Forschungsarbeit zeigen, welchen Bezug Grundschulkinder zur Nachrichtenwelt haben und welche Vorstellungen damit verbunden sind.

description: With combined hopping parameter and strong coupling expansions, we calculate a dimensionally reduced Polyakov-loop effective theory valid for heavy quarks at nonzero temperature and arbitrary chemical potential. We numerically compute the critical endpoint of the deconfinement transition as a function of quark masses and number of flavours. We also investigate the applicability of the model to the low-T and high density region, specifically in terms of baryon condensation phenomena.

description: Potential line emission at 111 and 129 GeV from 16 unassociated Fermi-LAT point sources has been reported recently by Su & Finkbeiner (2012c). Together with similar features seen by Fermi in a region near the Galactic Centre, the evidence has been interpreted as the spectral signature of dark matter annihilation or internal bremsstrahlung. Through a combination of supervised machine-learning algorithms and archival multiwavelength observations we find that 14 out of the 16 unassociated sources showing the line emission in the Su & Finkbeiner sample are most likely active galactic nuclei (AGN). Based on this new evidence, one must widen the range of possible solutions for the 100-140 GeV excess to include a very distinct astrophysical explanation. While we cannot rule out a dark matter origin for the line emission in the Galactic Centre, we posit that if the detection in the Su & Finkbeiner sample is indeed real it might be related to accretion, bubble, or jet activity in nearby (z < 0.2) AGN. Alternatively, given the right conditions, the similarity could be due to a chance occurrence caused by extragalactic background light (EBL) absorption. Or else one must concede that the features are an artefact of instrumental or calibration issues.

description: In the spaces $S^p$ of functions of several variables, $2π$-periodic in each variable, we study the approximative properties of operators $A^\vartriangle_{\varrho,r}$ and $P^\vartriangle_{\varrho,s}$, which generate two summation methods of multiple Fourier series on triangular regions. In particular, in the terms of approximation estimates of these operators, we give a constructive description of classes of functions, whose generalized derivatives belong to the classes $S^pH_ω$.
