description: The code FADO is the first publicly available population spectral synthesis tool that treats the contribution from ionised gas to the observed emission self-consistently. We study the impact of the nebular contribution on the determination of the star formation rate (SFR), stellar mass, and consequent effect on the star-forming main sequence (SFMS) at low redshift. We applied FADO to the spectral database of the SDSS to derive the physical properties of galaxies. As a comparison, we used the data in the MPA-JHU catalogue, which contains the properties of SDSS galaxies derived without the nebular contribution. We selected a sample of SF galaxies with H$α$ and H$β$ flux measurements, and we corrected the fluxes for the nebular extinction through the Balmer decrement. We then calculated the H$α$ luminosity to estimate the SFR. Then, by combining the stellar mass and SFR estimates from FADO and MPA-JHU, the SFMS was obtained. The H$α$ flux estimates are similar between FADO and MPA-JHU. Because the H$α$ flux was used as tracer of the SFR, FADO and MPA-JHU agree in their SFR. The stellar mass estimates are slightly higher for FADO than for MPA-JHU on average. However, considering the uncertainties, the differences are negligible. With similar SFR and stellar mass estimates, the derived SFMS is also similar between FADO and MPA-JHU. Our results show that for SDSS normal SF galaxies, the additional modelling of the nebular contribution does not affect the retrieved fluxes and consequentially also does not influence SFR estimators based on the extinction-corrected H$α$ luminosity. For the stellar masses, the results point to the same conclusion. These results are a consequence of the fact that the vast majority of normal SF galaxies in the SDSS have a low nebular contribution.

description: Recent news reports claim that China is overtaking the United States and all other countries in scientific productivity and scientific impact. A straightforward analysis of high-impact papers in astronomy reveals that this is not true in our field. In fact, the United States continues to host, by a large margin, the authors that lead high-impact papers. Moreover, this analysis shows that 90% of all high-impact papers in astronomy are led by authors based in North America and Europe. That is, only about 10% of countries in the world host astronomers that publish "astronomy's greatest hits".

description: With the urgent need to mitigate climate change and rising global temperatures, technological solutions that reduce atmospheric CO2 are an increasingly important part of the global solution. As a result, the nascent carbon capture, utilization, and storage (CCUS) industry is rapidly growing with a plethora of new technologies in many different sectors. There is a need to holistically evaluate these new technologies in a standardized and consistent manner to determine which technologies will be the most successful and competitive in the global marketplace to achieve decarbonization targets. Life cycle assessment (LCA) and techno-economic assessment (TEA) have been employed as rigorous methodologies for quantitatively measuring a technology's environmental impacts and techno-economic performance, respectively. However, these metrics evaluate a technology's performance in only three dimensions and do not directly incorporate stakeholder needs and values. In addition, technology developers frequently encounter trade-offs during design that increase one metric at the expense of the other. The technology performance level (TPL) combined indicator provides a comprehensive and holistic assessment of an emerging technology's potential, which is described by its techno-economic performance, environmental impacts, social impacts, safety considerations, market/deployability opportunities, use integration impacts, and general risks. TPL incorporates TEA and LCA outputs and quantifies the trade-offs between them directly using stakeholder feedback and requirements. In this article, the TPL methodology is being adapted from the marine energy domain to the CCUS domain. Adapted metrics and definitions, a stakeholder analysis, and a detailed foundation-based application of the systems engineering approach to CCUS are presented. The TPL assessment framework is couched within the internationally standardized LCA framework to improve technical rigor and acceptance. It is demonstrated how stakeholder needs and values can be directly incorporated, how LCA and TEA metrics can be balanced, and how other dimensions (listed earlier) can be integrated into a single metric that measures a technology's potential.

description: Das Aufteilen von periodischen Programmen auf mehrere CPUs eines MPSoC kann schwer, wenn nicht unmöglich sein wenn sie mehr Resourcen benötigen als das System zur Verfügung hat. Die Genauigkeit der Ausgabe kann verringert werden indem nicht jede Instanz ausgeführt wird, eine Methode durch die die Aufteilung leichter fällt. Eine weiterer Ansatz ist die Genauigkeit zu verringern ist die Integration von CPUs, die annähernde Ergebnisse liefern. Gängige Algorithmen sind jedoch nicht auf die besonderen Erfordernisse derartiger Systeme eingestellt und können unter Umständen eine Aufteilung erzeugen die ungültig ist. In dieser Arbeit werden Algorithmen prästeniert, die auf diese Erfordernisse eingehen können und dadurch die Aufteilung erleichtern. Die Resultate zeigen, dass die Integration von derartigen CPUs nicht nur die Aufteilung verbessern, sondern auch besser ausgeführt werden können. Diese Beobachtung liefert eine weitere Methode mit der die Genauigkeit eines Systems verringert werden kann ohne Programm Instanzen völlig auszulassen.
description: Trying to assign a set of periodic tasks to the Central processing unit (CPU)s of a Multi-Processor Systemon a Chip (MPSoC) that can be easily scheduled can be hard if not impossible if the load if the tasksis too much for the CPUs to bear. Reducing the Quality of service (QoS) the system can achieve by omitting task instances has been evaluated and shown to improve the viability of task partitions. Using additional QoS degrading methods like the introduction of a CPUs using approximation can allow further improvements to the partition results and their schedulability. However, established partitioning algorithms do not take the special requirements of a MPSoC containing approximate CPUs into accountand possibly create an invalid task partition. In this thesis a partitioning algorithms are presented that are aware of approximation and can improve the resulting task partition. The results show, that the inclusion of CPUs using approximation allows task-sets to be partitioned more easily. Additionallyscheduling the resulting partitions yields longer execution using established scheduling algorithms.This observation shows another QoS degrading method of lowering the processor utilization that is notas drastic as the outright omitting the execution of task instances.

description: The existence of bottlenecks often leads to the stagnation of pedestrian gatherings, which seriously affects the efficiency of traffic and reduces the flow of pedestrians. Some studies have shown that setting devices in front of bottlenecks can promote pedestrian evacuation under certain conditions. In this paper, the effect of setting diversion devices in front of the exit on pedestrian flow is studied. From our observation, these diversion devices can form a buffer zone before the exit and affect pedestrian behaviors. The evacuation times are found to decrease as the devices became farther away from the exit. In our experiments, it is found that the effect of shunt piles on evacuation is better than in the case of safety barriers and without device conditions. Under the condition of setting up safety barriers approximately 1m and 3m in front of the exit, the evacuation times are extended by 0.88% and 2.67%. For shunt piles, the evacuation times are 11.53% and 14.96% shorter than that of those without a device regarding the different distances to exit (1m and 3m, respectively). In addition, setting up shunt piles reduces the time interval between two consecutive pedestrians. To sum up, in our experimental settings, the diversion devices can effectively improve the average speed ahead of the exit and promote evacuation to become more orderly, which reduces the congestion in the later period of evacuation. In other words, this study demonstrates that a reasonable layout of facilities can not only meet the daily functional requirements but also improve the efficient use of space in emergencies, reducing the probability of crowd conventions and jams.

description: Employing a recently-developed dispersive optical model (DOM) which allows a complete description of experimental data both above (up to 200 MeV) and below the Fermi energy in $^{40}$Ca, we demonstrate that elastic nucleon-nucleus scattering data constrain the spectral strength in the continuum of orbits that are nominally bound in the independent-particle model. In the energy domain between 0 and 200 MeV, the integrated strength or depletion number is highly sensitive to the separation of the IPM orbit to the scattering continuum. This sensitivity is determined by the influence of the surface-absorption properties of the DOM self-energy. For an ab initio calculation employing the self-energy of the charge-dependent Bonn (CDBonn) interaction which only includes the effect of short-range correlations, no such sensitivity is obtained and a depletion of 4% is predicted between 0 and 200 MeV irrespective of the orbit. The ab initio spectral strength generated with the CDBonn interaction approaches the empirical DOM spectral strength at 200 MeV. Both spectral distributions allow for an additional 3-5% of the strength at even higher energies which is associated with the influence of short-range correlations. We suggest that the non-local form of the DOM allows for an analysis of elastic-nucleon-scattering data that directly determines the depletion of bound orbits. While obviously relevant for the analysis of elastic nucleon scattering on stable targets, this conclusion holds equally well for experiments involving rare isotopes in inverse kinematics as well as experiments with electrons on atoms or molecules.

description: Zwischen den Betrugsvorwürfen gegen die Bloggerin Marie Sophie Hingst alias Fräulein ReadOn am 31. Mai 2019 im Spiegel und dem Selbstmord der Bloggerin im Juli 2019 und noch darüber hinaus fand in der deutschen Blogosphäre ein online und stellenweise sehr emotional geführter Diskurs über den Frame der Authentizität am Beispiel der Bloggerin Hingst statt. Nach der qualitativen Auswertung eines Korpus‘ von 15 Blogs, die auch untereinander vernetzt sind, lässt sich der Frame Authentizität in weitere Subframes zu Echtheit, Fiktion, Identität, Lüge, Name, Persönlichkeit, Pseudonym, Täuschen, Verantwortung, Vertrauen, Wahrheit und Wirklichkeit unterteilen und auf diese Art und Weise analysieren. Belegstellen zu diesen Subframes wurden im Korpus annotiert und ausgewertet. Die Blogosphäre, die teilweise mit Hingst persönlich in Kontakt stand, teilweise auch ihre Blogposts kommentiert, gelikt und geteilt, sie also aktiv authentifiziert hat, befasst sich in den analysierten Blogposts u.a. mit den Auswirkungen des Betrugs auf die Authentizität von Hingst, auf die von Hingsts Blogposts, auf die Authentizität der eigenen Blogger:innen-Identität und der Publikationsform des Blogs generell. Da Hingst außerdem Historikerin war und behauptet hatte eine Jüdin, deren Angehörige im Holocaust umgekommen sind, zu sein, wird der Frame Authentizität im vorliegenden Diskurs u.a. in zwei dominanten Kontexten verwendet: im Kontext des Holocaust und im Kontext der Persönlichkeitsstörung.

description: Techniques are developed for creating new and general language families of only semilinear languages, and for showing families only contain semilinear languages. It is shown that for language families L that are semilinear full trios, the smallest full AFL containing L that is also closed under intersection with languages in NCM (where NCM is the family of languages accepted by NFAs augmented with reversal-bounded counters), is also semilinear. If these closure properties are effective, this also immediately implies decidability of membership, emptiness, and infiniteness for these general families. From the general techniques, new grammar systems are given that are extensions of well-known families of semilinear full trios, whereby it is implied that these extensions must only describe semilinear languages. This also implies positive decidability properties for the new systems. Some characterizations of the new families are also given.

description: About $39$ years ago, Kaplansky conjectured that the dimension of a semisimple Hopf algebra over an algebraically closed field of characteristic zero is divisible by the dimensions of its simple modules. Although it still remains open, some partial answers to this conjecture play an important role in classifying semisimple Hopf algebras. This paper focuses on the recent development of Kaplansky's sixth conjecture and its applications in classifying semisimple Hopf algebras.

description: Objectives: Acquired brain injury (ABI) has long-lasting effects, and patients and their families require continued care and support, often for the rest of their lives. For many individuals living with an ABI disorder, nonpharmacological rehabilitation treatment care has become increasingly important care component and relevant for informed healthcare decision making. Our study aimed to appraise economic evidence on the cost-effectiveness of nonpharmacological interventions for individuals living with an ABI. Methods: This systematic review was registered in PROSPERO (CRD42020187469), and a protocol article was subject to peer review. Searches were conducted across several databases for articles published from inception to 2021. Study quality was assessed according the Consolidated Health Economic Evaluation Reporting Standards checklist and Population, Intervention, Control, and Outcomes criteria. Results: Of the 3772 articles reviewed 41 publications met the inclusion criteria. There was a considerable heterogeneity in methodological approaches, target populations, study time frames, and perspectives and comparators used. Keeping these issues in mind, we find that 4 multidisciplinary interventions studies concluded that fast-track specialized services were cheaper and more cost-effective than usual care, with cost savings ranging from £253 to £6063. In 3 neuropsychological studies, findings suggested that meditated therapy was more effective and saved money than usual care. In 4 early supported discharge studies, interventions were dominant over usual care, with cost savings ranging from £142 to £1760. Conclusions: The cost-effectiveness evidence of different nonpharmacological rehabilitation treatments is scant. More robust evidence is needed to determine the value of these and other interventions across the ABI care pathway.

description: Any audio recording encapsulates the unique fingerprint of the associated acoustic environment, namely the background noise and reverberation. Considering the scenario of a room equipped with a fixed smart speaker device with one or more microphones and a wearable smart device (watch, glasses or smartphone), we employed the improved proportionate normalized least mean square adaptive filter to estimate the relative room impulse response mapping the audio recordings of the two devices. We performed inter-device distance estimation by exploiting a new set of features obtained extending the definition of some acoustic attributes of the room impulse response to its relative version. In combination with the sparseness measure of the estimated relative room impulse response, the relative features allow precise inter-device distance estimation which can be exploited for tasks such as best microphone selection or acoustic scene analysis. Experimental results from simulated rooms of different dimensions and reverberation times demonstrate the effectiveness of this computationally lightweight approach for smart home acoustic ranging applications

description: Many aspects of the three-dimensional (3-D) structure and evolution of interplanetary coronal mass ejections (ICMEs) remain unexplained. Here, we investigate two main topics: (1) the coherence scale of magnetic fields inside ICMEs, and (2) the dynamic nature of ICME magnetic complexity. We simulate ICMEs interacting with different solar winds using the linear force-free spheromak model incorporated into the EUHFORIA model. We place a swarm of ~20000 spacecraft in the 3-D simulation domain and characterize ICME magnetic complexity and coherence at each spacecraft based on simulated time series. Our simulations suggest that ICMEs retain a lower complexity and higher coherence along their magnetic axis, but that a characterization of their global complexity requires crossings along both the axial and perpendicular directions. For an ICME of initial half angular width of $45^\circ$ that does not interact with other large-scale solar wind structures, global complexity can be characterized by as little as 7-12 spacecraft separated by $25^\circ$, but the minimum number of spacecraft rises to 50-65 (separated by $10^\circ$) if interactions occur. Without interactions, ICME coherence extends for $45^\circ$, $20^\circ$-$30^\circ$, $15^\circ$-$30^\circ$, and $0^\circ$-$10^\circ$ for $B$, $B_ϕ$, $B_θ$, and $B_r$, respectively. Coherence is also lower in the ICME west flank compared to the east flank due to Parker spiral effects. Moreover, coherence is reduced by a factor of 3-6 by interactions with solar wind structures. Our findings help constrain some of the critical scales that control the evolution of ICMEs and aid in the planning of future dedicated multi-spacecraft missions.

description: Data-based mathematical modeling of biochemical reaction networks, e.g. by nonlinear ordinary differential equation (ODE) models, has been successfully applied. In this context, parameter estimation and uncertainty analysis is a major task in order to assess the quality of the description of the system by the model. Recently, a broadened eigenvalue spectrum of the Hessian matrix of the objective function covering orders of magnitudes was observed and has been termed as sloppiness. In this work, we investigate the origin of sloppiness from structures in the sensitivity matrix arising from the properties of the model topology and the experimental design. Furthermore, we present strategies using optimal experimental design methods in order to circumvent the sloppiness issue and present non-sloppy designs for a benchmark model.

description: Electrically-controlled dynamics of fluids and particles at microscales is a fascinating area of research with applications ranging from microfluidics and sensing to sorting of biomolecules. The driving mechanisms are electric forces acting on spatially separated charges in an isotropic medium such as water. Here we demonstrate that anisotropic conductivity of liquid crystals enables new mechanism of highly efficient electro-osmosis rooted in space charging of regions with distorted orientation. The electric field acts on these distortion-separated charges to induce liquid crystal-enabled electro-osmosis (LCEO). LCEO velocities grow with the square of the field, which allows one to use an AC field to drive steady flows and to avoid electrode damage. Ionic currents in liquid crystals that have been traditionally considered as an undesirable feature in displays, offer a broad platform for versatile applications such as liquid crystal enabled electrokinetics, micropumping and mixing.

description: Heterogeneous networks have a key role in the design of future mobile communication networks, since the employment of small cells around a macrocell enhances the network's efficiency and decreases complexity and power demand. Moreover, research on Blind Interference Alignment (BIA) has shown that optimal Degrees of Freedom (DoF) can be achieved in certain network architectures, with no requirement of Channel State Information (CSI) at the transmitters. Our contribution is a generalised model of BIA in a heterogeneous network with one macrocell with K users and K femtocells each with one user, by using Kronecker (Tensor) Product representation. We introduce a solution on how to vary beamforming vectors under power constraints to maximize the sum rate of the network and how optimal DoF can be achieved over K+1 time slots.

description: Pseudo two-colour diagrams or Chromosome maps (ChM) indicate that NGC 2808 host five different stellar populations. The existing ChMs have been derived by the Hubble Space Telescope photometry, and comprise of stars in a small field of view around the cluster centre. To overcome these limitations, we built a ChM with U,B,I photometry from ground-based facilities that disentangle the multiple stellar populations of NGC 2808 over a wider field of view. We used spectra collected by GIRAFFE@VLT in a sample of 70 red giant branch (RGB) and seven asymptotic giant branch (AGB) stars to infer the abundances of C, N, O, Al, Fe, and Ni, which combined with literature data for other elements (Li, Na, Mg, Si, Ca, Sc, Ti, Cr and Mn), and together with both the classical and the new ground-based ChMs, provide the most complete chemical characterisation of the stellar populations in NGC 2808 available to date. As typical of the multiple population phenomenon in globular clusters, the light elements vary from one stellar population to another; whereas the iron peak elements show negligible variation between the different populations (at a level of $\lesssim0.10$~dex). Our AGB stars are also characterised by the chemical variations associated with the presence of multiple populations, confirming that this phase of stellar evolution is affected by the phenomenon as well. Intriguingly, we detected one extreme O-poor AGB star (consistent with a high He abundance), challenging stellar evolution models which suggest that highly He-enriched stars should avoid the AGB phase and evolve as AGB-manqué star.

Collective Activity Bursting in a Population of Excitable Units Adaptively Coupled to a Pool of Resources

description: We study the collective dynamics in a population of excitable units (neurons) adaptively interacting with a pool of resources. The resource pool is influenced by the average activity of the population, whereas the feedback from the resources to the population is comprised of components acting homogeneously or inhomogeneously on individual units of the population. Moreover, the resource pool dynamics is assumed to be slow and has an oscillatory degree of freedom. We show that the feedback loop between the population and the resources can give rise to collective activity bursting in the population. To explain the mechanisms behind this emergent phenomenon, we combine the Ott-Antonsen reduction for the collective dynamics of the population and singular perturbation theory to obtain a reduced system describing the interaction between the population mean field and the resources.
Why do migrant workers rely more often on referrals?

description: Intuitively, one can expect that migrant workers have smaller social networks in the new destination country and by that smaller probability of finding a job through referrals. However, empirical analysis of the SOEP data from 2002 to 2008 show that 41.21% of migrant workers and 31.79% of native workers found their current job through referrals. Estimation results of the panel probit model with random effects show that 7.26% statistically significant difference of the predicted probabilities of using referrals between migrant and native workers is not explained by the characteristics of the individuals and firms. In order to explain this puzzle, this paper presents a search and matching model with heterogeneous worker groups and several search channels. The firm observes the noisy signal of the productivity, the nationality and the search channel of the worker to form unbiased expectations about the true productivity of the worker. The probabilities to be hired for the two worker groups and different search channels are determined using ex-ante union bargained wage and expectations of the firm. Calibration results of the model show that even when migrant workers have smaller size of the social network, they gain more from recommendations, because their employment chances are initially much lower than employment chances of native workers.

description: We explore the observability of the neutral hydrogen (HI) and the singly-ionized isotope helium-3 ($^3$HeII) in the intergalactic medium (IGM) from the Epoch of Reionization down to the local Universe. The hyperfine transition of $^3$HeII, which is not as well known as the HI transition, has energy splitting corresponding to 8 cm. It also has a larger spontaneous decay rate than that of neutral hydrogen, whereas its primordial abundance is much smaller. Although both species are mostly ionized in the IGM, the balance between ionization and recombination in moderately high density regions renders them abundant enough to be observed. We estimate the emission signal of both hyperfine transitions from large scale filamentary structures and discuss the prospects for observing them with current and future radio telescopes. We conclude that HI in filaments is possibly observable even with current telescopes after 100 hours of observation. On the other hand, $^3$HeII is only detectable with future telescopes, such as SKA, after the same amount of time.
