description: Paleoaltimetry - the reconstruction of the elevation of mountain ranges in the geological past - is key to understanding the geodynamic drivers of surface uplift. Simultaneously, surface uplift of Earth’s major mountain ranges redirected atmospheric flow and impacted climate globally. At a smaller scale, mountain building affects regional climate and biodiversity. Stable isotope paleoaltimetry is a powerful tool to quantify the past elevation of mountain ranges. It is based on the inverse relationship between the stable isotopic composition of meteoric waters and elevation, which is represented by the so-called isotopic lapse rate. However, variations in climatic parameters modify isotopic lapse rates and impact moisture transport over the continents and consequently affect paleoelevation reconstructions. Here, we show the results of a combined stable isotope paleoaltimetry and paleoclimate modeling approach in the European Alps. This approach allows for an improved and more realistic estimation of isotopic lapse rates, large-scale isotope-in-precipitation patterns over Europe and hence Alpine paleoaltimetry calculations. The European Alps are an ideal target for a combined paleoaltimetry - climate modeling approach, given that they are (a) one of the most-studied mountain ranges for which many geoscientific data are available, and (b) sufficiently small and oriented near-parallel to dominant atmospheric circulation patterns. The latter implies that no major global climatic changes are expected in response to Alpine surface uplift, as opposed to e.g. the Andes or the Tibet-Himalaya mountain ranges. Results from 4D-MB SPP phase 1 and 2 show that: (1) Changing the surface elevation of even a small orogen can complicate stable isotope paleoaltimetry by mixing the elevation and climate signal in a more complex way than commonly assumed. Climate models can help separate these signals and constrain surface uplift histories. (2) The Central Alps were already high during the Early and Middle Miocene, whereas the Eastern Alps were still at significantly lower elevations, thereby confirming that surface uplift propagated from west to east, as would be expected from oblique continent-continent collision. Together, the results highlight the importance and viability of this combined, interdisciplinary approach. Based on the results from 4D-MB SPP phase 1 and 2, we propose that future efforts to reconstruct surface uplift of mountain ranges follow this state-of-the-art approach, while keeping local limitations to proxy material availability and access to facilities in mind.

description: Recently, indications for an emission line at 3.55 keV have been found in the combined spectra of a large number of galaxy clusters and also in Andromeda. This line could not be identified with any known spectral line. It is tempting to speculate that it has its origin in the decay of a particle contributing all or part of the dark matter. In this note we want to point out that axion-like particles being all or part of the dark matter are an ideal candidate to produce such a feature. More importantly the parameter values necessary are quite feasible in extensions of the Standard Model based on string theory and could be linked up to a variety of other intriguing phenomena, which also potentially allow for new tests of this speculation.

description: La Convención Biológica de Diversidad (CBD) estableció como objetivo proteger el 10% de todas las áreas marinas y costeras para el 2020, mediante áreas protegidas y otras medidas de conservación. Al 2012 sólo el 2.3% del total de la superficie oceánica se encontraba bajo una categoría de protección.1 Además varias Áreas Marinas Protegidas (AMPs) enfrentan importantes deficiencias, y el mal desempeño puede estar asociado con debilidades en las reglas formales e informales (instituciones) que influyen su gobernanza. Esta situación es particularmente problemática en países en vías de desarrollo, tema que abordamos al examinar las AMPs en Costa Rica. Costa Rica tiene una larga historia en conservación y últimamente ha trabajado en mejorar sus AMPs. Esto brinda la oportunidad de observar cómo se han reproducido los desafíos de gobernanza en el tiempo y la forma en que los actores están tratando de superarlos. Para explicar el estado actual de la gestión de AMPs en Costa Rica, utilizamos un enfoque de investigación cualitativo basado en las teorías de estabilidad y cambio institucional, y formulamos cuatro preguntas clave: ¿Cuáles son los retos actuales en la gobernanza de AMPs en Costa Rica? ¿Cómo emergieron estos retos en el tiempo? ¿Qué mejoras se han llevado a cabo? ¿Cuáles temas necesitan ser abordados y por qué?

Publisher: name: Wiley-VCH
Year: 2023

description: In times of an ever‐increasing demand for portable energy storage systems, post‐lithium‐based battery systems are increasingly coming into the focus of current research. In this realm, zinc–air batteries can be considered a very promising candidate to expand the existing portfolio of lithium‐based rechargeable battery systems due to their high theoretical energy density of 1086 Wh kg⁻¹. Despite a steady increase in research over the past 5 years, a breakthrough in realizing fully electrically rechargeable zinc–air batteries has yet to come. This perspective article highlights pitfalls that have probably hampered the development of rechargeable zinc–air batteries over years. This involves a fundamental evaluation of the zinc–air battery system, whereby fallacies of an alleged rechargeability are uncovered. Especially, the electrode balancing of the zinc anode as well as the interface between anode and electrolyte is focused herein. Known phenomena such as morphological changes are re‐evaluated by taking the contrasting battery stresses from shallow discharge to a highly desirable deep discharge into account. Existing challenges are discussed and prospected based on current approaches aiming to shed new light on a fundamental understanding and an opening of new avenues for rechargeability in zinc–air batteries.
Methodology to Optimally Place Pressure Sensors for Leak Detection in Water Distribution Systems using Value of Information and Entropy

Publisher: name: Zenodo
Year: 2021
Subjects: Water Distribution Networks, Leak detection, Optimisation, Value of Information

description: The presence of leaks in water distribution networks (WDN) is a very common problem that impacts these systems in a variety of ways, including the loss of drinking water, the deterioration of the quality of supply water due to the intrusion of substances into the system, the structural damage caused by infiltrations, and the uneven distribution of pressures and flows in the network, among others. For this reason, the use of sensors to identify possible where leaks could be located, and to operate the network is imperative. However, placing the sensors in the network is not a trivial problem, due to the complexities of the networks, the uncertainties around them, and the limited resources.
 Although many researchers have proposed different methodologies for locating sensors, methods accounting for the costs of the decision-making situation and the nature of the decision-maker are very limited. Moreover, the existing methods largely rely on demand-driven analysis approaches, which limit their applicability.
 This thesis presents a methodology to determine the optimal location of pressure sensors for identifying the existence of leaks in water distribution systems. The methodology is based on two unrelated concepts, Value of Information (VOI) and Entropy. The former is common in areas such as medicine and economics but with very limited application in water distribution systems. The latter is a concept from Information Theory, which have been used in the past for locating sensors in the water environment. The proposed methodology, which has a simplified framework with practical interpretation, involves the judgment of decision-makers and switches from the assumption of a demand-driven analysis to a more realistic approach in which the demands are a function of the pressure's system (pressure-driven analysis). Additionally, the methodology considers, to a certain extent, the possible sources of uncertainty and parameter variation along time, towards robust solutions.
 The methodology is applied in the case study of the city of Braila, in Romania, which has the goal of reducing water losses caused by leaks by a value of 50 L/h/km. Results show that the sensor locations obtained agree with previous methods in simpler networks, and that well distributed sensors are obtained, although the performance of the method is depending on the selection of the threshold in pressure that is considered critical. A by-product of this research is the Sensor Detection Value (SDV) index, which is based on VOI concepts and that facilitate the application of the methodology and the interpretation of the results.

description: The microwave properties of glass-fibers reinforced polymer composite embedded with an orthogonal array of Fe77Si10B10C3 microwires have been investigated. The composites containing orthogonal wire arrays display a remarkable transmission window in the frequency band of 1 to 6 GHz under zero external magnetic field indicating an intrinsic double-negative-index characteristic. The polymer matrices have proved to exert a synergistic effect on the microwave properties, which is responsible for the disappearance of the transmission windows when Ek is perpendicular to the glass fiber direction. The plasma frequency of the orthogonal microwire array composite is higher than that of the parallel microwire array with identical wire spacing; this could be attributed to the enhanced microwire-wave interaction induced by the axial electrical components on the additional layer of perpendicular wires. All these features make this new kind of orthogonal microwire composites promising for potential cloaking and sensing applications.

Strong polygamy of quantum correlations in multi-party quantum systems

subject: FOS: Physical sciences

description: We propose a new type of polygamy inequality for multi-party quantum entanglement. We first consider the possible amount of bipartite entanglement distributed between a fixed party and any subset of the rest parties in a multi-party quantum system. By using the summation of these distributed entanglements, we provide an upper bound of the distributed entanglement between a party and the rest in multi-party quantum systems. We then show that this upper bound also plays as a lower bound of the usual polygamy inequality, therefore the strong polygamy of multi-party quantum entanglement. For the case of multi-party pure states, we further show that the strong polygamy of entanglement implies the strong polygamy of quantum discord.

description: The GoTriple discovery platform is based on an extensible ingestion platform that supports the harvesting of repositories by using the standard OAI-PMH protocol. The platform is open and welcomes data providers that want to see their contents’ metadata indexed in GoTriple. Besides large aggregators like Isidore, OpenAIRE, DOAJ and BASE in fact, GoTriple has already integrated several smaller publications and research data archives. To ease the onboarding of new providers, a specific web application, the Harvesting Management System, has been developed. It easily allows data providers to register to the platform and propose one or more SSH-related data sources+ accessible via OAI-PMH. These “proposed sources” will be later verified by GoTriple administrators, both to test the technical correctness of the import process and to ensure the relevance of the acquired data in the context of SSH. During this workshop, we will present the whole process for becoming a GoTriple provider through a step-by-step approach. We welcome real prospect users with whom we can live test the integration of their repositories in GoTriple. No specific technical knowledge is needed to participate in this session but in case you want to participate in the tests, the coordinates of your OAI-PMH endpoint are needed: its URL, the data model used (Dublin Core or Europeana Data Model), and the set to harvest.

Topics in Kondo insulators
Creators: name: Wugalter, Ari
Publisher: name: No Publisher Supplied
Year: 2020

description: We have studied Kondo insulator states in the single and two-channel Kondo models. The Kondo insulator state shows remarkable optical properties. Specifically, a dielectric constant which is ≈ 100 times higher than for a regular insulator. Moreover, the diamagnetic permeability does not seem to be affected by the onset of the Kondo effect. This suggest that while the Kondo effect is very effective in suppressing the longitudinal current fluctuations, it is largely ineffective in its influence on diamagnetic currents.In the two channel Kondo model, we observe the formation of a half-Kondo insulator, where the spontaneous breaking of channel symmetry leads to the formation of a Kondo insulator in one channel, while the other channel remains metallic. We discuss, how this phenomenon can be understood using the concept of order fractionalization, in which the channel magnetization breaks up into an emergent spinor order parameter. By integrating out the fermions we derive an effective action that describes this symmetry breaking and its emergent collective modes. A remarkable observation is that topological defects in the order parameter carry a U(1) flux, manifested in the Aharonov-Bohm phase picked by electrons that orbit the defect. By studying the effective action, we argue that the phase diagram contains a non-magnetic transition between a large and a small Fermi surface.
Ultra-low acoustic-phonon-limited mobility and giant phonon-drag thermopower in MgZnO/ZnO heterostructures

description: We present numerical simulations of the acoustic-phonon-limited mobility, $μ_{ac}$, and phonon-drag thermopower, $S^{g}$, in two-dimensional electron gases confined in MgZnO/ZnO heterostructures. The calculations are based on the Boltzmann equation and are made for temperatures in the range 0.3-20 K and sheet densities $0.5$-$30\times 10^{15}$ m$^{-2}$. The theoretical estimations of $μ_{ac}$ are in good agreement with the experiment without any adjustable parameters. We find that the magnitude of $μ_{ac}$ is dramatically decreased in relation to GaAs based heterostructures. The phonon-drag thermopower, $S^{g}$, which according to Herring's expression is inversely proportional to $μ_{ac}$ is severely increased exceeding 200 mV/K at $T=5$ K depending on sheet density. The giant values of $S^{g}$ lead to a strong improvement of the figure of merit $ZT$ at low temperatures. Our findings suggest that MgZnO/ZnO heterostructures can be candidates for good thermoelectric materials at cryogenic temperatures.

description: Asteroids with satellites are natural laboratories to constrain the formation and evolution of our solar system. The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. Based on W.M. Keck adaptive optics observations, we found a unique and stable orbital solution, which is uncommon in comparison to the orbits of other large multiple asteroid systems studied so far. From lightcurve observations recorded since 1957, we showed that because the large Req=125-km primary may be made of two joint lobes, the moon could be ejecta of the low-velocity encounter, which formed the system. The inferred density of Hektor's system is comparable to the L5 Trojan doublet (617) Patroclus but due to their difference in physical properties and in reflectance spectra, both captured Trojan asteroids could have a different composition and origin.

description: In this study tensiometric measurements have been carried out to study the host- guest inclusion complexes in the presence of micellar media. The encapsulation effect on the micellar parameters has been analyzed. Thermodynamics of the systems was discussed in terms of the change in standard free energy of micellization. The values of critical micelle concentration, maximum surface excess concentration and minimum area per molecule of the surfactant at air-liquid interface have been evaluated. The resulting parameters allow the observation of concomitant reorganizations occurring in the system.

description: A striking difference along the Alpine Orogen is the style of collisional tectonics during the Oligo-Miocene, with the onset of escape tectonics in the Eastern Alps (Fig. 1A). The indentation of the Adriatic Plate into the Eastern Alpine Orogen resulted in the formation of conjugate dextral and sinistral strike-slip faults in the vicinity of the Tauern Window. Moreover, major changes occurred in the foreland of the Eastern and Southern Alps in the Early Miocene, with the cessation of the northern Alpine front propagation and the onset of thrusting along the Southern Alpine Front. In this study, we present new results from structural, stratigraphic and subsidence analyses of the eastern North Alpine Foreland Basin (NAFB; Fig. 1B) as part of the “Mountain Building in 4 Dimensions” project, German branch of the European AlpArray initiative, which aims at better understanding the deep crustal-mantle structures of the Alpine Orogen and their relation to surface processes. Our results show a first phase of onset of foreland sedimentation in the eastern NAFB between c. 33-28 Ma, followed by a strong tectonic-driven subsidence between c. 28-25 Ma ending by a phase of erosion and the formation of a basin-wide Northern Slope Unconformity (NSU; Fig. 1C & 1D). During this time period, the rift-related Mesozoic normal faults of the European platform were reactivated and are capped by the NSU (Fig. 1D). We interpret this phase as an increase in the flexure of the subducting European Plate under the growing Alpine Orogen. Between 25-19 Ma, the eastern NAFB remained in a deep-marine, underfilled state with a gently increase in subsidence. A major shift took place around 19-17 Ma with strong tectonic-driven uplift, ranging from 200 m (absolute minimum) to 1200 m depending on uncertainties on paleo-water depths, and rapid sedimentary infill of the basin (Fig. 1C & 1D). We discuss the possible causes for this major tectono-sedimentary shift in the eastern NAFB in relation to contemporaneous changes in collisional tectonics within the Eastern and Southern Alps, and with a potential Early Miocene slab break-off event beneath the Eastern Alps.

description: We present a mechanism for the stabilization of colloids in liquid mixtures without use of surfactants or polymers. When a suitable salt is added to a solvent mixture, the coupling of the colloid's surface chemistry and the preferential solvation of ions leads to a repulsive force between colloids that can overcome van der Waals attraction. This repulsive force is substantial in a large range of temperatures, mixture composition and salt concentrations. The increased repulsion due to addition of salt occurs even for charged colloids. This mechanism may be useful in experimental situations where steric stabilization with surfactants or polymers is undesired.

description: With the current global projection of over 130 million electric vehicles (EVs), there soon will be a need for battery waste management. Especially for all‐solid‐state lithium‐ion batteries (lithium ASSBs), aspects of waste management and circular economy have not been addressed so far. Within such ASSBs, the use of solid‐electrolytes like garnet‐type Li₆.₅La₃Zr₁.₅Ta₀.₅O₁₂ (LLZTO) may shift focus on strategies to recover not only the transition metal elements but also elements like La/Zr/Ta. In this work, we present a two‐step recycling approach using citric acid as the leaching agent to separate and recover the individual components of a model cell comprising of Li₄Ti₅O₁₂ (LTO) anode, Li₆.₅La₃Zr₁.₅Ta₀.₅O₁₂ (LLZTO) garnet electrolyte and LiNi₁/₃Mn₁/₃Co₁/₃O₂ (NMC) cathode. We observe that by adjusting the concentration of citric acid, it was possible to separate the materials from each other without strong mixing of individual phases and also to maintain their principle performance characteristics. Thus, the process developed has a potential for upscaling and can guide towards considering separation capability of battery components in the development of lithium ASSBs.
Understanding the evolution of close binary systems with radio pulsars

description: We calculate the evolution of close binary systems (CBSs) formed by a neutron star (behaving as a radio pulsar) and a normal donor star, evolving either to helium white dwarf (HeWD) or ultra short orbital period systems. We consider X-ray irradiation feedback and evaporation due to radio pulsar irradiation. We show that irradiation feedback leads to cyclic mass transfer episodes, allowing CBSs to be observed in-between as binary radio pulsars under conditions in which standard, non-irradiated models predict the occurrence of a low mass X-ray binary. This behavior accounts for the existence of a family of eclipsing binary systems known as redbacks. We predict that redback companions should almost fill their Roche lobe, as observed in PSR J1723-2837. This state is also possible for systems evolving with larger orbital periods. Therefore, binary radio pulsars with companion star masses usually interpreted as larger than expected to produce HeWDs may also result in such {\it quasi - Roche Lobe Overflow} states, rather than hosting a carbon-oxygen WD. We found that CBSs with initial orbital periods $\mathrm{P_{i}<1}$ day evolve into redbacks. Some of them produce low mass HeWDs, and a subgroup with shorter $\mathrm{P_{i}}$ become black widows (BWs). Thus, BWs descent from redbacks, although not all redbacks evolve into BWs. There is mounting observational evidence favoring that BW pulsars are very massive ($\mathrm{\gtrsim 2\; M_{\odot}}$). As they should be redback descendants, redback pulsars should also be very massive, since most of the mass is transferred before this stage.

McGehee regularization of general SO(3)-invariant potentials and applications to stationary and spherically symmetric spacetimes

description: The McGehee regularization is a method to study the singularity at the origin of the dynamical system describing a point particle in a plane moving under the action of a power-law potential. It was used by Belbruno and Pretorius to perform a dynamical system regularization of the singularity at the center of the motion of massless test particles in the Schwarzschild spacetime. In this paper, we generalize the McGehee transformation so that we can regularize the singularity at the origin of the dynamical system describing the motion of causal geodesics (timelike or null) in any stationary and spherically symmetric spacetime of Kerr-Schild form. We first show that the geodesics for both massive and massless particles can be described globally in the Kerr-Schild spacetime as the motion of a Newtonian point particle in a suitable radial potential and study the conditions under which the central singularity can be regularized using an extension of the McGehee method. As an example, we apply these results to causal geodesics in the Schwarzschild and Reissner-Nordström spacetimes. Interestingly, the geodesic trajectories in the whole maximal extension of both spacetimes can be described by a single two-dimensional phase space with non-trivial topology. This topology arises from the presence of excluded regions in the phase space determined by the condition that the tangent vector of the geodesic be causal and future directed.

Data driven techniques for modal decomposition and reduced-order modelling of fluids
Creators: name: Beit-Sadi, Mohammad
Publisher: name: Imperial College London
Year: 2023

description: In this thesis, a number of data-driven techniques are proposed for the analysis and extraction of reduced-order models of fluid flows. Throughout the thesis, there has been an emphasis on the practicality and interpretability of data-driven feature-extraction techniques to aid practitioners in flow-control and estimation. The first contribution uses a graph theoretic approach to analyse the similarity of modes extracted using data-driven modal decomposition algorithms to give a more intuitive understanding of the degrees of freedom in the underlying system. The method extracts clusters of spatially and spectrally similar modes by post-processing the modes extracted using DMD and its variants. The second contribution proposes a method for extracting coherent structures, using snapshots of high dimensional measurements, that can be mapped to a low dimensional output of the system. The importance of finding such coherent structures is that in the context of active flow control and estimation, the practitioner often has to rely on a limited number of measurable outputs to estimate the state of the flow. Therefore, ensuring that the extracted flow features can be mapped to the measured outputs of the system can be beneficial for estimating the state of the flow. The third contribution concentrates on using neural networks for exploiting the nonlinear relationships amongst linearly extracted modal time series to find a reduced order state, which can then be used for modelling the dynamics of the flow. The method utilises recurrent neural networks to find an encoding of a high dimensional set of modal time series, and fully connected neural networks to find a mapping between the encoded state and the physically interpretable modal coefficients. As a result of this architecture, the significantly reduced-order representation maintains an automatically extracted relationship to a higher-dimensional, interpretable state.

Approximate Bayesian computation and agent based modelling for inference of size dependence in stochastic gene expressionof Size Dependence in Stochastic Gene Expression
Creators: name: Bowman, Anthony
Publisher: name: Imperial College London
Year: 2023

description: Gene expression is an inherently stochastic process, but it is also subject to sources of extrinsic noise. Chief among these sources is the cell cycle, both through its different stages, but also through the change in cell size that happens throughout it. In order to fully understand these sources of variability, mathematical modelling and quantitative gene expression data must be combined. Unfortunately, when working with agent-based models of gene expression that incorporate the cell cycle, we do not have access to an analytical likelihood function. These types of models can only be simulated. Approximate Bayesian computation (ABC) is a class of simulation-based likelihood free inference methods that is useful for dealing with problems of this nature. In this thesis we have firstly developed more efficient ABC methods for model selection that can help us decide among different competing biological mechanisms. Secondly we have integrated models of gene expression, including the totally asymmetric exclusion process (TASEP), into the cell cycle. We have done so by developing agent-based models of growing and dividing cells, where each cell contains biochemical reactions. In this way, we are able to couple gene expression to cell size and the cell cycle. Finally, in collaboration with biologists, we have applied these models and our ABC methods to single cell transcription and cell size snapshot data in S.pombe, in order to uncover the precise molecular mechanisms that control transcription rates scaling with cell size. We find that transcription of both constitutive and periodic genes is a Poisson process with transcription rates scaling with cell size and without evidence for transcriptional off states. Modelling and experimental data indicate that scaling relies on the coordination of RNA polymerase II (RNAPII) transcription initiation rates with cell size and that RNAPII is a limiting factor. Our modeling results are validated by real-time quantitative imaging that shows size increase is accompanied by a rapid concentrationindependent recruitment of RNAPII onto chromatin. Overall, this thesis highlights applications of mathematical modelling and statistical inference to biological data, to uncover biological mechanisms

description: We first recall the connection, going back to A. Thue, between rational approximation to algebraic numbers and integer solutions of some Diophantine equations. Next we recall the equivalence between several finiteness results on various Diophantine equations. We also give many equivalent statements of Mahler's generalization of the fundamental theorem of Thue. In particular, we show that the theorem of Thue--Mahler for degree $3$ implies the theorem of Thue--Mahler for arbitrary degree $\ge3$, and we relate it with a theorem of Siegel on the rational integral points of the projective line $¶^1(K)$ minus $3$ points. Finally we extend our study to higher dimensional spaces in connection with Schmidt's Subspace Theorem.

description: The energy shortages of the recent past have prompted a keen awareness of the pervasiveness of direct and indirect energy utilization in the domestic economy. Analysis of the relationship of energy to various components of the economic system requires treatment of the components in a total economic setting. Since the United States has a consistent set of national income accounts and their production account transforms into a sectoral input-output (I/O) tableau, I/O techniques appear to be a feasible way of incorporating this interrelatedness. The model utilized in this study is the readily available I/O construct incorporated into a linear programming framework and appended with BTU energy requirements and employment and value-added data. The impacts of energy resource shortages are explored for a representation of the food and fiber system in the context of sector interdependence.

Type II Seesaw Origin of Non-zero $θ_{13}, δ_{CP} $ and Leptogenesis

description: We discuss the possible origin of non-zero reactor mixing angle $θ_{13}$ and Dirac CP phase $δ_{CP}$ in the leptonic sector from a combination of type I and type II seesaw mechanisms. Type I seesaw contribution to neutrino mass matrix is of tri-bimaximal (TBM) type which gives rise to vanishing $θ_{13}$ leaving the Dirac CP phase undetermined. If the Dirac neutrino mass matrix is assumed to take the diagonal charged lepton type structure, such a TBM type neutrino mass matrix originating from type I seesaw corresponds to real values of Dirac Yukawa couplings in the terms $Y_{ij} \bar{L_i} H N_j$. This makes the process of right handed heavy neutrino decay into a light neutrino and Higgs $(N \rightarrow νH)$ CP preserving ruling out the possibility of leptogenesis. Here we consider the type II seesaw term as the common origin of non-zero $θ_{13}$ and $δ_{CP}$ by taking it as a perturbation to the leading order TBM type neutrino mass matrix. First, we numerically fit the type I seesaw term by taking oscillation as well as cosmology data and then compute the predictions for neutrino parameters after the type II seesaw term is introduced. We consider a minimal structure of the type II seesaw term and check whether the predictions for neutrino parameters lie in the $3σ$ range. We also compute the predictions for baryon asymmetry of the Universe by considering type II seesaw term as the only source of CP violation and compare it with the latest cosmology data.

Innovation Dynamics & Modelling

description: EUPRO is a core facility to investigate structure, dynamics and impacts of project-based R&D collaboration to grasp and understand the development of the European Research Area (ERA). Advanced research in this direction needs constant EUPRO updates, but also extensions to other transnational and national research funding activities. NATPRO addresses this gap by providing a systematic information basis on nationally funded R&D projects, and by focussing on specific national funding programmes and selected countries depending on data availability. NATPRO extension will be able to respond to interesting policy questions, such as the relation between national and European funding, in terms of thematic complementarity and/or organisational overlapping; structure and dynamics of multi-level networks, featuring nodes (organisations) acting at the national level, at the European level, or at both levels (‘gatekeeper’); and relationships between a set of characteristics of organisations and their ability to attract national vs. European funding.

description: Supernovae provide a backdrop from which we can probe the end state of stellar evolution in the final years before the progenitor star explodes. As the shock from the supernova expands, the timespan of mass loss history we are able to probe also extends, providing insight to rapid time-scale processes that govern the end state of massive stars. While supernovae transition into remnants on timescales of decades to centuries, observations of this phase are currently limited. Here we present observations of SN 1970G, serendipitously observed during the monitoring campaign of SN 2011fe that shares the same host galaxy. Utilizing the new Jansky Very Large Array upgrade and a deep X-ray exposure taken by the Chandra Space Telescope, we are able to recover this middle-aged supernova and distinctly resolve it from the HII cloud with which it is associated. We find that the flux density of SN 1970G has changed significantly since it was last observed - the X-ray luminosity has increased by a factor of ~3, while we observe a significantly lower radio flux of only 27.5 micro-Jy at 6.75 GHz, a level only detectable through the upgrades now in operation at the Jansky Very Large Array. These changes suggest that SN 1970G has entered a new stage of evolution towards a supernova remnant, and we may be detecting the turn-on of the pulsar wind nebula. Deep radio observations of additional middle-aged supernovae with the improved radio facilities will provide a statistical census of the delicate transition period between supernova and remnant.

description: This Professional Report explores the connection between Accessory Dwelling Units (ADUs) and the housing aims of the age-friendly movement, seeking to appraise the efficacy of ADU adoption as a viable solution for the delivery of affordable housing for older persons in Austin, who are seeking to successfully age in place. This research reviews the existing ADU and relevant Senior Planning literature. Interviews with relevant professional actors in the City of Austin with insights into senior planning efforts and housing development in Austin are represented here. This report finds that ADUs face significant regulatory barriers that prevent them from being an easily adopted affordable housing solutions for seniors in Austin but can and should be an ongoing player in Austin’s larger affordable housing efforts. This report engages with the case study cities of Austin and Los Angeles, in the attempt to understand the status of their current Age-friendly plans, and to draw forth applicable lessons for ADU-related approaches. The secondary case study of Portland offers a positive example of ADU progress in the United States that is covered here as well. Lessons relevant to ADUs are connected to relevant senior planning documents, specifically the City of Austin’s “Age-Friendly Austin Action Plan,” and Los Angeles’ “Purposeful Aging Los Angeles: An Age-Friendly Initiative.” In pursuit of addressing the needs of elder populations with goals of aging in place, the housing typology of ADUs are compared with alternative affordable housing approaches. The recommendations indicated by this report reinforce the findings of the City of Austin audit titled “City Services for Older Adults.” Further recommendations are provided in support of a strategy tying ADUs and seniors together in Austin that may offer support for some seniors, before concluding with a broader recommendation in favor of statewide zoning reform. The recommendations include a call for increased staffing for Austin's Age-friendly efforts, improved data collection on senior service usage, and for further financing research to be conducted by city staff in pursuit of affordable housing solutions for seniors.
