description: Die Technologiekosten erneuerbarer Energien sind in den letzten Jahren stark gefallen. Es hängt jedoch vom Vergütungsrahmen ab, in welchem Umfang StromverbraucherInnen von diesen Kostensenkungen profitieren können. Berechnungen mit einem Finanzierungsmodell zeigen, dass die derzeit geltende gleitende Marktprämie zunehmend zu erhöhten Finanzierungskosten führt, was den sinkenden Technologiekosten entgegenwirkt. Zudem können steigende Eigenkapitalanforderungen sich negativ auf die Akteursvielfalt bei Investitionen in erneuerbare Energien und die Realisierungsraten von Projekten auswirken. Abhilfe kann eine Weiterentwicklung des Vergütungsrahmens hin zu Differenzverträgen schaffen. Differenzverträge führen zu geringen Finanzierungskosten und verringern damit auch die Gesamtkosten der erneuerbaren Stromversorgung in der Größenordnung von jährlich 0,8 Milliarden Euro im Jahr 2030. Zudem sichern sie StromverbraucherInnen gegen hohe Zahlungen für erneuerbaren Strom im Fall hoher Strompreise ab. Mit einem Übergang zu Differenzverträgen ergibt sich zugleich die Chance, die Anreize für eine systemfreundliche Standortwahl und Auslegung der Anlagen wirksamer und einfacher zu gestalten.

description: Die geplante Mütterrente II wird bei unverändertem aktuellem Rentenwert die Rentenausgaben um jährlich 3,5 Milliarden Euro erhöhen. Begünstigt werden Rentnerinnen mit vor 1992 geborenen Kindern bei mindestens drei Kindern. Nach Berechnungen auf Basis des Sozio-oekonomischen Panels (SOEP) betrifft dies fast ein Viertel aller Rentnerinnen. Simulationsrechnungen zeigen, dass die Mütterrente II überproportional Rentnerinnen mit niedrigen Haushaltseinkommen zugutekommt, da diese häufiger drei oder mehr Kinder haben. In den unteren 20 Prozent der Einkommensverteilung steigen die Einkommen der begünstigten Rentnerinnen um durchschnittlich sechs Prozent, bei alleinlebenden Frauen ab 75 Jahren um 8,5 Prozent. Die übrigen Rentnerhaushalte werden mit durchschnittlich 0,4 Prozent des Einkommens belastet, da die Reform die Rentenanpassungen der kommenden Jahre reduzieren wird. Die verringerte Rentenanpassung macht in den nächsten Jahren etwa 40 Prozent des Ausgangsfinanzierungsvolumens der Reform aus – insoweit wird die Reform von der Rentnergeneration mit finanziert. ArbeitnehmerInnen und ArbeitgeberInnen werden durch höhere Rentenbeitragssätze belastet. Zudem steigt der steuerfinanzierte Bundeszuschuss, was die SteuerzahlerInnen belastet.

description: Under a magnetic field along its axis, domain wall motion in a uniaxial nanowire is much slower than in the fully anisotropic case, typically by several orders of magnitude (the square of the dimensionless Gilbert damping parameter). However, with the addition of a magnetic field transverse to the wire, this behaviour is dramatically reversed; up to a critical field strength, analogous to the Walker breakdown field, domain walls in a uniaxial wire propagate faster than in a fully anisotropic wire (without transverse field). Beyond this critical field strength, precessional motion sets in, and the mean velocity decreases. Our results are based on leading-order analytic calculations of the velocity and critical field as well as numerical solutions of the Landau-Lifshitz-Gilbert equation.

description: We present a formula for tunneling conductance in ballistic ferromagnet/ferromagnetic insulator/superconductor junctions where the superconducting state has opposite spin pairing symmetry. The formula can involve correctly a ferromagnetism has been induced by effective mass difference between up- and down-spin electrons. Then, this effective mass mismatch ferromagnet and standard Stoner ferromagnet have been employed in this paper. As an application of the formulation, we have studied the tunneling effect for junctions including spin-triplet p-wave superconductor. The conductace spectra show a clear difference between two ferromagnets depending upon the way of normalization of the conductance. Especially, a essential difference is seen in zero-bias conductance peaks reflecting characteristics of each ferromagnets. From obtained results, it will be suggested that the measurements of the tunneling conductance in the junction provide us a useful information about the mechanism of itinerant ferromagnetism in metal.

So ist der durchschnittliche Stundenlohn unter Verwendung der vertraglichen Arbeitszeit im untersten Dezil der Lohnverteilung zwischen 2014 und 2015 um rund sieben Prozent und zwischen 2015 und 2016 nochmals um sechs Prozent gestiegen. Das Lohnwachstum im unteren Lohnsegment ist gerade in solchen Regionen stark, in denen besonders viele Beschäftigte vor der Reform unter 8,50 Euro verdienten. So ist der Stundenlohn durch die Mindestlohnreform im untersten Fünftel der regionalen Lohnverteilungen um 5,8 Prozent, beziehungsweise 56 Cent, gestiegen. Gleichzeitig ist allerdings die Arbeitszeit im unteren Lohnsegment zurückgegangen, so dass sich der Bruttomonatsverdienst der anspruchsberechtigten Beschäftigten mit niedrigen Löhnen kaum verändert hat. Insofern bleibt abzuwarten, ob die Reform den intendierten Beitrag zur Stabilisierung der sozialen Sicherungssysteme im Sinne steigender sozialversicherungspflichtiger Entgelte leisten kann.

description: Objective: To provide a detailed and differentiated description of the path to receiving the correct amyotrophic lateral sclerosis (ALS) diagnosis, including delay times, referrals, alternate diagnoses, and clinical progression. Methods: Medical records until the date of ALS diagnosis were reviewed and linked to the Swedish Motor Neuron Disease Quality Registry. Results: The study included 353 Stockholm ALS patients diagnosed in 2016–2021. Patients were divided into four groups: 117 (33.1%) with lower extremity (LE), 85 (24.1%) with upper extremity (UE), 136 (38.5%) with bulbar, and 15 (4.2%) with respiratory onset. The time from onset to diagnosis was 16.0 (9.4–27.5) months in LE, 12.9 (8.8–17.8) months in UE, 11.7 (7.4–16.0) months in bulbar, and 8.3 (4.7–15.6) months in respiratory onset. Patients with UE or LE onset were often referred to orthopedics or a spinal/hand surgery clinic (29.3% for LE and 41.8% for UE), while bulbar patients were more frequently referred to ENT (66.3%). For those with LE or UE onset, the most common alternate diagnosis was spinal/foraminal stenosis whereas myasthenia gravis and stroke were more common for bulbar onset patients. For the respiratory group, cardiopulmonary diagnoses predominated. The proportion of all patients in King’s stage 3 or 4 increased from 11.3% to 46.1% from the initial health care visit to diagnosis. Conclusions: There was great variation in the path to ALS diagnosis according to the onset clinical phenotype. In all groups, the diagnostic delay and clinical progression was substantial. We identified subgroups where the delay was the longest and might be reduced.

description: In reported experiments, a steel indenter was pressed into a soft elastomer layer under varying inclination angles and subsequently was detached under various inclination angles too. The processes of indentation and detachment were recorded with a video camera, and the time dependences of the normal and tangential components of the contact force and the contact area, as well as the average contact pressure and average tangential stresses, were measured as functions of the inclination angle. Based on experimental results, a simple theoretical model of the indentation process is proposed, in which tangential and normal contacts are considered independently. Both experimental and theoretical results show that at small indentation angles (when the direction of motion is close to tangential), a mode with elastomer slippage relative to the indenter is observed, which leads to complex dynamic processes—the rearrangement of the contact boundary and the propagation of elastic waves (similar to Schallamach waves). If the angle is close to the normal angle, there is no slipping in the contact plane during the entire indentation (detachment) phase.

description: Fission-fragment mass distributions are asymmetric in fission of typical actinide nuclei for nucleon number $A$ in the range $228 \lnsim A \lnsim 258$ and proton number $Z$ in the range $90\lnsim Z \lnsim 100$. For somewhat lighter systems it has been observed that fission mass distributions are usually symmetric. However, a recent experiment showed that fission of $^{180}$Hg following electron capture on $^{180}$Tl is asymmetric. We calculate potential-energy surfaces for a typical actinide nucleus and for 12 even isotopes in the range $^{178}$Hg--$^{200}$Hg, to investigate the similarities and differences of actinide compared to mercury potential surfaces and to what extent fission-fragment properties, in particular shell structure, relate to the structure of the static potential-energy surfaces. Potential-energy surfaces are calculated in the macroscopic-microscopic approach as functions of fiveshape coordinates for more than five million shapes. The structure of the surfaces are investigated by use of an immersion technique. We determine properties of minima, saddle points, valleys, and ridges between valleys in the 5D shape-coordinate space. Along the mercury isotope chain the barrier heights and the ridge heights and persistence with elongation vary significantly and show no obvious connection to possible fragment shell structure, in contrast to the actinide region, where there is a deep asymmetric valley extending from the saddle point to scission. The mechanism of asymmetric fission must be very different in the lighter proton-rich mercury isotopes compared to the actinide region and is apparently unrelated to fragment shell structure. Isotopes lighter than $^{192}$Hg have the saddle point blocked from a deep symmetric valley by a significant ridge. The ridge vanishes for the heavier Hg isotopes, for which we would expect a qualitatively different asymmetry of the fragments.

description: We investigated effects of a Rashba-type spin-orbit coupling (SOC) on the condensed density and superfluid density tensor of a two-component Fermi gas in the BCS-BEC crossover at zero temperature. In anisotropic three dimensions (3D), we found that SOC has an opposite effect on condensation (enhanced) and superfluidity (suppressed in the SOC direction) and this effect becomes most pronounced for very weak interactions and the SOC strength being larger than a characteristic value. Furthermore, as functions of SOC strength, the condensed density changes monotonously for all interaction parameters while the superfluid density has a minimum when the interaction parameter is below a critical value. We also discussed the isotropic two dimensional (2D) case where analytical expressions for the gap and number equations were obtained and the same phenomena was found as that of the 3D case.

description: Liquid metal embrittlement (LME) cracking is a phenomenon observed during resistance spot welding (RSW) of zinc−coated advanced high−strength steels (AHSS) in automotive manufacturing. In this study, severe cracks are observed at the edge of the sheet under reduced flange widths. These cracks, traversing the AHSS sheet, culminate at the edge with a width of approximately 1.2 mm. Through combined numerical and experimental investigations, and material testing, these cracks are identified and validated as a new type of LME crack. The mechanism behind this crack formation is attributed to unique geometric conditions that, when compared to center welding, amplify radial material flow by ninefold to 0.87 mm. The resultant tangential tensile stresses approximate 760 MPa, which exceed the yield strength of the examined advanced high−strength steel (AHSS) under heightened temperature conditions, and when combined with liquid zinc, promote the formation of this new type of LME crack.

Der Projektbetreiber und einige europäische Energieversorgungsunternehmen argumentieren, es handele sich um ein privatwirtschaftlich angelegtes, rentables Investitionsprojekt, das für die Versorgungssicherheit Deutschlands und Europas mit Erdgas notwendig sei. Analysen des DIW Berlin zeigen, dass das geplante Pipelineprojekt Nord Stream 2 zur Sicherung der Erdgasversorgung in Deutschland und Europa nicht notwendig ist. Die dem Projekt zugrundeliegenden energiewirtschaftlichen Analysen, insbesondere das EU-Referenzszenario, überschätzen den deutschen und europäischen Erdgasbedarf erheblich. Auf der Angebotsseite ist keine Versorgungslücke für den Fall, dass Nord Stream 2 nicht gebaut wird, zu erkennen. Unterschiedliche Wirtschaftlichkeitsrechnungen legen zudem nahe, dass mit dem Projekt hohe Verluste bis in Milliardenhöhe zu erwarten sind. Ebenso ist unklar, wie stark sich Nord Stream 2 auf Erdgaskunden in Deutschland auswirken würde.

description: The question of whether the Universe is spatially homogeneous and isotropic on the largest scales is of fundamental importance to cosmology, but has not yet been answered decisively. Surprisingly, neither an isotropic primary CMB nor combined observations of luminosity distances and galaxy number counts are sufficient to establish such a result. The inclusion of the Sunyaev-Zel'dovich effect in CMB observations, however, dramatically improves this situation. We show that even a solitary observer who sees an isotropic blackbody CMB can conclude that the universe is homogeneous and isotropic in their causal past when the Sunyaev-Zel'dovich effect is present. Critically, however, the CMB must either be viewed for an extended period of time, or CMB photons that have scattered more than once must be detected. This result provides a theoretical underpinning for testing the Cosmological Principle with observations of the CMB alone.

Role of external carbon and metal salt dosing in membrane bioreactor system to achieve limits of technology nutrient removal from municipal wastewater
Creators: name: Pattanayak, Soubhagya Kumar
Publisher: name: University of British Columbia
Year: 2014

description: Membrane bioreactor (MBR) technology in conjunction with conventional biological nutrient removal has been demonstrated to be successful in recent years. However, the limits of technology (LoT) effluent goal, ≤ 3 mg TN/L (total nitrogen) and ≤ 0.1 mg TP/L (total phosphorus), could potentially push a system to the limits of its capability. The broad objective of the long-term PhD study was to investigate role of external dosing of alum in a membrane biological nutrient removal (MBNR) system targeting LoT effluent nutrient levels. Two parallel MBNR systems, modified Bardenpho configuration, were operated under similar process conditions with metal salt addition being the only difference. The continuous flow MBNR system performance data signified the importance of external methanol and alum dosing in accomplishing the LoT nutrient removal goal. The stoichiometric methanol ratio, i.e. mg methanol required / mg NO₃-N removed, was calculated to be 6.1 in reducing average permeate NO₃-N concentration to 1.4 mg/L. Similarly, an average molar Al/TP ratio of 1.9 was required to reduce PO₄-P concentration to 0.07 mg/L in the permeate. Chemical phosphorus removal did not have any influence on COD removal, nitrification (except for a brief period) and denitrification. The relationship between chemical P removal and enhanced biological phosphorus removal (EBPR) was dynamic and was dependent on alum dosage concentration. At high dosage levels (i.e. 80 mg/L), alum supplementation competed with and finally, inhibited EBPR until the MBNR system was converted to a chemical P removal system. Activated sludge modeling was undertaken to analyze its suitability in predicting the performance of an MBNR system targeting LoT goals. The model was successful in predicting nitrogen removal, while parameter calibration was required for fitting of the measured suspended solids and EBPR data. Moreover, the model could not predict the relationship between the simultaneous biological and chemical P removal accurately. A direct batch DON measurement method, batch anion exchange resin adsorption followed by persulfate digestion, was developed and validated successfully. Using the method, the DON contribution to permeate total nitrogen was observed to vary from 7 percent to 96 percent in the parallel MBNR systems, when permeate TN concentrations were less than 3 mg/L.

description: The object of this thesis is the exhibitional and narrative design of a collaborative spatial museological model tool, in relation to the museum of the Ancient Fora in Thessaloniki, named ThessArchaia. The spatial final proposal is substantiated by a theoretical study of the imperatives and conditions of the new museology, as it evolved through the academic dialogue, but also the extraordinary recent public health conditions. This study was prepared with the intention of creating an alternative approach regarding the inevitable hybridity of the museum of the future, which differs from the reasoning of open-air museums, but which is also placed closer to the future visitor of a monument or a group through the use of new technologies. The dual form of the design proposal is also a different version in the design of an exhibition stand with mobile features and cultural versus commercial qualities. Its methodology began with the theoretical research of the field of interest and then concluded with the museological architectural design of the proposal. Overall it presents a hybrid museum alternative in response to the current question of what the future of the museum will be.

description: In this work, the quark-hadron phase transition in a chameleon Brans-Dicke model of brane world cosmology within an effective model of QCD is investigated. Whereas, in the chameleon Brans-Dicke model of brane world cosmology, the Friedmann equation and conservation of density energy are modified, resulting in an increased expansion in the early Universe. These have important effects on quark-hadron phase transitions. We investigate the evolution of the physical quantities relevant to quantitative descriptions of the early times, namely, the energy density, $ρ$, temperature, $T$, and the scale factor, $a$, before, during, and after the phase transition. We do this for smooth crossover formalism in which lattice QCD data is used for obtaining the matter equation of state and first order phase transition formalism. Our analyses show that the quark-hadron phase transition has occurred at approximately one nanosecond after the big bang and the general behavior of temperature is similar in both of two approaches.

Ab initio based polarizable force field generation and application to liquid silica and magnesia

description: We extend the program potfit, which generates effective atomic interaction potentials from ab initio data, to electrostatic interactions and induced dipoles. The potential parametrization algorithm uses the Wolf direct, pairwise summation method with spherical truncation. The polarizability of oxygen atoms is modeled with the Tangney-Scandolo interatomic force field approach. Due to the Wolf summation, the computational effort in simulation scales linearly in the number of particles, despite the presence of electrostatic interactions. Thus, this model allows to perform large-scale molecular dynamics simulations of metal oxides with realistic potentials. Details of the implementation are given, and the generation of potentials for SiO2 and MgO is demonstrated. The approach is validated by simulations of microstructural, thermodynamic and vibrational properties of liquid silica and magnesia.

Democracy

description: An oft-heard criticism of the digital age is that too much power is concentrated in the hands of too few individuals. An infrastructure that is both democratic and designed to serve the common good, particularly one utilized by social platforms, conflicts fundamentally with the business models of large commercial platforms. Unsurprisingly, current debates about common-good alternatives to the standard commercial platforms are thus increasingly focusing on the so-called fediverse. As a portmanteau combining the words “federation” and “universe,” the term “fediverse” refers to a collection of interoperable, decentralized social networks and other online services that are independent but able to communicate with each other. 

By moving away from profit-oriented logics, decentralized networks for the purpose of communication pose a genuine threat to dominant power structures. As decisions relevant to technical design, user management, and content moderation are now distributed among various instances (i.e., communities with their own rules and culture), the focus is once again on communication and interaction, rather than advancing the profit maximization of platform economies.

description: Im Grundstoffsektor, ein gewichtiger Emittent von Treibhausgasen weltweit, werden Emissionsminderungspotentiale noch unzureichend ausgeschöpft. Vor allem von Möglichkeiten der Substitution von Materialien, des verbesserten Produktdesigns oder des Recyclings und der Wiederverwendung von Produkten wird zu wenig Gebrauch gemacht. Um diese Potentiale zu erschließen, muss in Europa ein kohärenter Politikrahmen entstehen, der es erlaubt, das Portfolio von Emissionsminderungspotentialen zu erschließen. Hier werden vier Bereiche, in denen prioritär und zeitnah gehandelt werden muss, sowie die zugehörigen Politikinstrumente vorgestellt. Der Umfang und die Qualität von Recycling müssen gesteigert werden; Märkte für klimafreundliche Produkte und Technologien müssen geschaffen werden, sowohl kurzfristig für die Etablierung von Innovationen auf dem Markt, als auch langfristig durch CO2-Preissignale; die Emissionen aus CO2-intensiven Prozessen und Technologien müssen reduziert werden.

description: Primordial Black Holes (PBH's) can form in the early Universe from the collapse of large density fluctuations. Tight observational limits on their abundance constrain the amplitude of the primordial fluctuations on very small scales which can not otherwise be constrained, with PBH's only forming from the extremely rare large fluctuations. The number of PBH's formed is therefore sensitive to small changes in the shape of the tail of the fluctuation distribution, which itself depends on the amount of non-Gaussianity present. We study, for the first time, how quadratic and cubic local non-Gaussianity of arbitrary size (parameterised by f_nl and g_nl respectively) affects the PBH abundance and the resulting constraints on the amplitude of the fluctuations on very small scales. Intriguingly we find that even non-linearity parameters of order unity have a significant impact on the PBH abundance. The sign of the non-Gaussianity is particularly important, with the constraint on the allowed fluctuation amplitude tightening by an order of magnitude as f_nl changes from just -0.5 to 0.5. We find that if PBH's are observed in the future, then regardless of the amplitude of the fluctuations, non-negligible negative f_nl would be ruled out. Finally we show that g_nl can have an even larger effect on the number of PBH's formed than f_nl.

description: In the classical theorems of extreme value theory the limits of suitably rescaled maxima of sequences of independent, identically distributed random variables are studied. So far, only affine rescalings have been considered. We show, however, that more general rescalings are natural and lead to new limit distributions, apart from the Gumbel, Weibull, and Fréchet families. The problem is approached using the language of Renormalization Group transformations in the space of probability densities. The limit distributions are fixed points of the transformation and the study of the differential around them allows a local analysis of the domains of attraction and the computation of finite-size corrections.

description: We use a recent approach to soft-gluon resummation based on effective field theory to implement soft-gluon resummation at NNNLL order for slepton-pair production in SUSY extensions of the Standard Model. This approach resums large logarithmic corrections arising from the dynamical enhancement of the partonic threshold region caused by steeply falling parton luminosities. We evaluate the resummed invariant-mass distribution and total cross section for slepton-pair production at the Tevatron and LHC, matching our results onto NLO fixed-order calculations. As a byproduct, we also study virtual SUSY effects in the context of soft-gluon resummation for the Drell-Yan process.

description: Rydberg spin waves are optically excited in a quasi-one-dimensional atomic sample of Rb atoms. Pair-wise spin-wave correlations are observed by a spatially selective transfer of the quantum state onto a light field and photoelectric correlation measurements of the light. The correlations are interpreted in terms of the dephasing of multiply-excited spin waves by long-range Rydberg interactions.

description: We construct explicitly the canonical transformation that controls the full dependence (local and non-local) of the vertex functional of a Yang-Mills theory on a background field. After showing that the canonical transformation found is nothing but a direct field-theoretic generalization of the Lie transform of classical analytical mechanics, we comment on a number of possible applications, and in particular the non perturbative implementation of the background field method on the lattice, the background field formulation of the two particle irreducible formalism, and, finally, the formulation of the Schwinger-Dyson series in the presence of topologically non-trivial configurations.
