description: Many efforts have been made to image the spatiotemporal electrical activity of the brain, with the purpose of mapping its function and dysfunction, as well as aiding the management of brain disorders. Here, I develop a novel deep learning-based source imaging framework (DeepSIF), that provides robust and precise spatiotemporal estimates of underlying brain dynamics from non-invasive high-density electroencephalography (EEG) and magnetoencephalography (MEG) recordings. DeepSIF employs synthetic training data generated by biophysical models capable of modeling mesoscale brain dynamics. The rich characteristics of underlying brain sources are embedded in the realistic training data and implicitly learned by DeepSIF networks, avoiding complications associated with explicitly formulating and tuning priors in an optimization problem, as often is the case, in conventional source imaging approaches.
 I first demonstrate the necessity of using a realistic source model, such as a brain network model consisting of interconnected neural mass models, for the training data. Then, deep neural networks are trained and evaluated by (1) series of comprehensive numerical experiments, (2) imaging sensory and cognitive brain responses in a total of 20 healthy subjects from three public datasets, and (3) rigorously validating DeepSIF’s capability in identifying epileptogenic regions in a total cohort of 64 drug-resistant epilepsy patients by comparing DeepSIF results with invasive measurements and surgical resection outcomes. Interictal spike from EEG or MEG recordings, as well as ictal recordings from EEG recordings from three different clinical centers are used as the input for the trained DeepSIF networks.
 DeepSIF demonstrates robust and excellent performance, producing results that are concordant with common neuroscience knowledge about sensory and cognitive information processing, as well as clinical findings about the location and extent of the epileptogenic tissue, outperforming conventional source imaging methods. The DeepSIF method, as a novel data-driven imaging framework, demonstrates its versatility at adapting to different tasks as a general ESI framework. It enables efficient and effective high-resolution functional imaging of spatiotemporal brain dynamics, suggesting its wide applicability and value to neuroscience research and clinical applications.

title: Kapitalismus versus Marktwirtschaft. Karl Marx und Fernand Braudel
Creators: name: Faber, Malte

Publisher: name: University of Heidelberg
Year: 2018

description: Since the beginning of the finance crisis, the notion of capitalism and the adjective capitalistic are more and more employed in public discourse without making an attempt to define it. In contrast, the concept of market economy is less used. We try in this paper to differentiate both concepts by going back to the approaches by Karl Marx (1818-1883) and Fernand Braudel (1902-1985). Marx does not use the term capitalism but only capitalistic production, while Braudel argues on the basis of a wealth of empirical evidence that one has to differentiate between capitalism and market economy, because he sees a contrast between them. For this reason, he has different view of a capitalistic economy as Marx has.

Failed-Detonation Supernovae: Sub-Luminous Low-Velocity Ia Supernovae and Their Kicked Remnant White Dwarfs with Iron-Rich Cores

description: Type Ia supernovae (SNe Ia) originate from the thermonuclear explosions of carbon-oxygen (C-O) white dwarfs (WDs). The single-degenerate scenario is a well-explored model of SNe Ia where unstable thermonuclear burning initiates in an accreting, Chandrasekhar-mass WD and forms an advancing flame. By several proposed physical processes the rising, burning material triggers a detonation, which subsequently consumes and unbinds the WD. However, if a detonation is not triggered and the deflagration is too weak to unbind the star, a completely different scenario unfolds. We explore the failure of the Gravitationally-Confined Detonation (GCD) mechanism of SNe Ia, and demonstrate through 2D and 3D simulations the properties of failed-detonation SNe. We show that failed-detonation SNe expel a few 0.1 solar masses of burned and partially-burned material and that a fraction of the material falls back onto the WD, polluting the remnant WD with intermediate-mass and iron-group elements, that likely segregate to the core forming an WD whose core is iron rich. The remaining material is asymmetrically ejected at velocities comparable to the escape velocity from the WD, and in response, the WD is kicked to velocities of a few hundred km/s. These kicks may unbind the binary and eject a runaway/hyper-velocity WD. Although the energy and ejected mass of the failed-detonation SN are a fraction of typical thermonuclear SNe, they are likely to appear as sub-luminous low-velocity SNe Ia. Such failed detonations might therefore explain or are related to the observed branch of peculiar SNe Ia, such as the family of low-velocity sub-luminous SNe (SN 2002cx/SN 2008ha-like SNe).

description: We present a prescription to calculate manifestly gauge invariant tree-level helicity amplitudes for arbitrary scattering processes with off-shell initial-state gluons within the kinematics of high-energy scattering. We show that it is equivalent to Lipatov's effective action approach, and show its computational potential through numerical calculations for scattering processes with several particles in the final state.

description: High elimination rates and concerns for horse welfare are important issues in endurance riding. Improved understanding of the causes of elimination could increase completion rates in this sport. We have identified pre-ride laboratory risk factors that enable an assessment of potential elimination before the ride. A longitudinal cohort study was performed among 49 healthy horses competing in the 160 km endurance ride at the 2016 World Championship of Endurance Riding in Samorin/Slovakia. Blood samples were taken before the event. For statistical evaluation, horses were categorized into three groups: finishers, lame horses, and metabolically eliminated horses. Risk factors were calculated for each group using multinominal logistic regression. δ-Aminolevulinic-dehydratase (ALAD), thiobarbituric acid reactive substances (TBARSs), iron, and serum amyloid A (SAA) were measured and did not show an impact on the race outcome, but elevated pre-ride superoxide dismutase (SOD) was shown to have an effect on lameness elimination (p = 0.011). It might serve as an indicator for withdrawing horses at risk of later elimination before endurance rides, ultimately resulting in lower elimination rates and an increase in overall horse welfare.

description: Efficient coordination between Mg2+ and vitamin D maintains adequate Ca2+ levels during lactation. This study explored the possible interaction between Mg2+ (0.3, 0.8, and 3 mM) and 1,25-dihydroxyvitamin D3 (1,25D; 0.05 and 5 nM) during osteogenesis using bovine mesenchymal stem cells. After 21 days, differentiated osteocytes were subjected to OsteoImage analysis, alkaline phosphatase (ALP) activity measurements, and immunocytochemistry of NT5E, ENG (endoglin), SP7 (osterix), SPP1 (osteopontin), and the BGLAP gene product osteocalcin. The mRNA expression of NT5E, THY1, ENG, SP7, BGLAP, CYP24A1, VDR, SLC41A1, SLC41A2, SLC41A3, TRPM6, TRPM7, and NIPA1 was also assessed. Reducing the Mg2+ concentration in the medium increased the accumulation of mineral hydroxyapatite and ALP activity. There was no change in the immunocytochemical localization of stem cell markers. Expression of CYP24A1 was higher in all groups receiving 5 nM 1,25D. There were tendencies for higher mRNA abundance of THY1, BGLAP, and NIPA1 in cells receiving 0.3 mM Mg2+ and 5 nM 1,25D. In conclusion, low levels of Mg2+ greatly enhanced the deposition of bone hydroxyapatite matrix. The effect of Mg2+ was not modulated by 1,25D, although the expression of certain genes (including BGLAP) tended to be increased by the combination of low Mg2+ and high 1,25D concentrations.
Perturbations and chaos in quantum maps

description: The local density of states (LDOS) is a distribution that characterizes the effect of perturbations on quantum systems. Recently, it was proposed a semiclassical theory for the LDOS of chaotic billiards and maps. This theory predicts that the LDOS is a Breit-Wigner distribution independent of the perturbation strength and also gives a semiclassical expression for the LDOS witdth. Here, we test the validity of such an approximation in quantum maps varying the degree of chaoticity, the region in phase space where the perturbation is applying and the intensity of the perturbation. We show that for highly chaotic maps or strong perturbations the semiclassical theory of the LDOS is accurate to describe the quantum distribution. Moreover, the width of the LDOS is also well represented for its semiclassical expression in the case of mixed classical dynamics.

title: Image analysis and modeling of cellular organization in micropatterned environments
Creators: name: Linke, Marco
Publisher: name: Heidelberg University Library
Year: 2017

description: In experimental cellular biophysics, it has become standard practice to control the shape and organization of adherent cells. For this purpose, micropatterned environments are being used, which are fabricated using techniques from materials science. Thereby, cell variability can be reduced, which facilitates statistical analysis and allows for a detailed comparison to mathematical models. In this thesis we combine image processing with computational modeling and use the normalization properties of micropatterned environments to investigate cellular organization. In the first part, we apply image analysis techniques to study cell shape and internal organization. For this, we first analyze how contractile polymer bundles, so-called stress fibers, determine the shape of adherent cells in two and three dimensions. Next, we investigate the detailed structure of such bundles and quantify their influence on cellular contraction dynamics. In the second part of the thesis we develop different computational modeling approaches to gain deeper understanding into the interplay between cell shape and the microtubule network. We propose models that are based either on stochastic simulations of polymers or on an effective continuum theory for liquid crystals. With these models we can explain experimental results and predict the internal architecture of cells adhering to micropatterned substrates.

Helioseismic Holography of an Artificial Submerged Sound Speed Perturbation and Implications for the Detection of Pre-Emergence Signatures of Active Regions
Creators: name: Braun, Douglas C.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We use a publicly available numerical wave-propagation simulation of Hartlep et al. 2011 to test the ability of helioseismic holography to detect signatures of a compact, fully submerged, 5% sound-speed perturbation placed at a depth of 50 Mm within a solar model. We find that helioseismic holography as employed in a nominal "lateral-vantage" or "deep-focus" geometry employing quadrants of an annular pupil is capable of detecting and characterizing the perturbation. A number of tests of the methodology, including the use of a plane-parallel approximation, the definition of travel-time shifts, the use of different phase-speed filters, and changes to the pupils, are also performed. It is found that travel-time shifts made using Gabor-wavelet fitting are essentially identical to those derived from the phase of the Fourier transform of the cross-covariance functions. The errors in travel-time shifts caused by the plane-parallel approximation can be minimized to less than a second for the depths and fields of view considered here. Based on the measured strength of the mean travel-time signal of the perturbation, no substantial improvement in sensitivity is produced by varying the analysis procedure from the nominal methodology in conformance with expectations. The measured travel-time shifts are essentially unchanged by varying the profile of the phase-speed filter or omitting the filter entirely. The method remains maximally sensitive when applied with pupils that are wide quadrants, as opposed to narrower quadrants or with pupils composed of smaller arcs. We discuss the significance of these results for the recent controversy regarding suspected pre-emergence signatures of active regions.

description: Waste can be replaced, but not destroyed. That was one of the main rules that Christian Unverzagt described in his 1991 classic with Volker Grassmuck "Das Müll-System. Eine metarealistische Bestandsaufnahme" (The Waste System. A Metarealistic Record). Waste is the troublesome and ecologically impurifying flip-side of modernity. More and more things produce more and more waste. Nowadays it has become a new resource to build industries on. Facing a completely garbage-saturated, polluted world, the challenge is, to let go of things, to let them be.

Reconstructing the accretion history of the Galaxy from the kinematics and metallicity distribution of halo stars

Publisher: name: Zenodo
Year: 2024

description: The ΛCDM model predicts a hierarchical formation for galaxies: the merging history is thus crucial to understand how they form and evolve. In the last twenty years, many accreted substructures have been found in the Galactic halo, identified as stellar over-densities in specific regions of kinematics-related spaces with different chemical properties. We analysed the outcomes of high-resolution N-body simulations, which modelled a Milky Way-type galaxy accreting a satellite with mass ratio 1:10, with different orbital parameters and initial metallicity gradients, in order to check whether these methods were solid or not. We found that energy and angular momentum are not generally conserved for such a massive satellite, due to the dynamical friction, thus resulting in the satellite stars redistributing over a large fraction of the E − Lz space. As a consequence, different regions of the E − Lz can feature different metallicity distribution functions (MDFs) even if caused by a single satellite merger event, due to the initial metallicity gradients. Nevertheless, we found some solid trends in the global properties of the MDFs when moving throughout the E − Lz space. This global coherence could be exploited to interpret the observational data, fact that would be crucial now, given the unprecedented data flow, driven by the Gaia mission and the complementary spectroscopic surveys.

description: We propose here the dark matter content of galaxies as a cold bosonic fluid composed of Weakly Interacting Slim Particles (WISPs), represented by spin-0 axion-like particles and spin-1 hidden bosons, thermalized in the Bose-Einstein condensation state and bounded by their self-gravitational potential. We analyze two zero-momentum configurations: the polar phases in which spin alignment of two neighbouring particles is anti-parallel and the ferromagnetic phases in which every particle spin is aligned in the same direction. Using the mean field approximation we derive the Gross-Pitaevskii equations for both cases, and, supposing the dark matter to be a polytropic fluid, we describe the particles density profile as Thomas-Fermi distributions characterized by the halo radii and in terms of the scattering lengths and mass of each particle. By comparing this model with data obtained from 42 spiral galaxies and 19 Low Surface Brightness (LSB) galaxies, we constrain the dark matter particle mass to the range $10^{-6}-10^{-4} eV$ and we find the lower bound for the scattering length to be of the order $10^{-14} fm$.

It is known that, in a certain extension of the warped extra dimension model, the third generation quarks could strongly couple to the KK gluon owing to appropriate bulk fermion mass parameters. Taking account of kinematical cuts to reduce background events, we show the model parameter space which leads to a significance larger than 5$σ$ with the integrated luminosity of 10 (100) ${\rm fb}^{-1}$.

description: The isostructural α-γ phase transition in cerium is analyzed using density-functional theory with different exchange-correlation functionals, in particular the PBE0 hybrid functional and the exact- exchange plus correlation in the random-phase approximation [(EX+cRPA)@PBE0] approach. We show that the Hartree-Fock exchange part of the hybrid functional actuates two distinct solutions at zero temperature that can be associated with the α and γ phases of cerium. However, despite the relatively good structural and magnetic properties, PBE0 predicts the γ phase to be the stable phase at ambient pressure and zero temperature, in contradiction with low temperature experiments. EX+cRPA reverses the energetic ordering, which emphasizes the importance of correlation for rare- earth systems.

description: Die Bedeutung eines bereits in der Grundschule beginnenden Fremdsprachenunterrichts beschäftigt die Bildungspolitik schon seit vielen Jahren und machte den Grundschulfremdsprachenunterricht in der Vergangenheit zu einem intensiv diskutierten Thema. Insbesondere die Frage nach der richtigen Sprachverwendung spielt dabei eine wichtige Rolle. Das Ziel der vorliegenden Arbeit ist es, herauszuarbeiten, ob der Fremdsprachenunterricht in der Grundschule ausschließlich in Französisch zu bestreiten ist, oder ob die Lehrkräfte situationsbedingt auch auf die deutsche Sprache zurückgreifen können. Anhand der historischen Entwicklung des Grundschulfremdsprachenunterrichts werden in der Arbeit zuerst die verschiedenen Ansätze und Konzepte in ihrem historischen Kontext aufgezeigt. Darauf aufbauend wird die gegenwärtige Situation in Deutschland dargelegt. Um ein Verständnis für die Besonderheiten eines grundschulgemäßen Fremdsprachenunterrichts zu schaffen, werden anschließend die Erkenntnisse aus der Spracherwerbsforschung zum Erst- und Zweitspracherwerb hinzugezogen und daraus Prinzipien des Grundschulfremdsprachenunterrichts formuliert. Die deutschlandweit unterschiedliche Handhabung macht es zudem notwendig, sich auf den Fremdsprachenunterricht eines Bundeslandes zu beschränken. Anhand der Vorgaben im Berliner Rahmenlehrplan werden die darin festgelegten Ziele des Grundschulfremdsprachenunterrichts aufgezeigt und auf mögliche Schwierigkeiten aufmerksam gemacht. Im Anschluss wird an die theoretischen Grundlagen angeknüpft und die Bedeutung der Sprachverwendung der Lehrkraft in den Blick genommen. Dabei wird die Frage aufgegriffen, ob die Lehrkraft in gewissen Situationen unterstützend auf die deutsche Sprache zurückgreifen darf. Es werden demgegenüber verschiedene Positionen beleuchtet und Perspektiven unterrichtender Lehrkräfte hinzugezogen. Darauf aufbauend werden abschließend Grundsätze zur Sprachverwendung der Lehrkraft aufgestellt und die Möglichkeiten sowie Begrenzungen in der Umsetzung diskutiert.

description: The heliosphere represents a uniquely accessible domain of space, where fundamental physical processes common to solar, astrophysical and laboratory plasmas can be studied under conditions impossible to reproduce on Earth and unfeasible to observe from astronomical distances. Solar Orbiter, the first mission of ESA's Cosmic Vision 2015-2025 programme, will address the central question of heliophysics: How does the Sun create and control the heliosphere? In this paper, we present the scientific goals of the mission and provide an overview of the mission implementation.

description: The influence of bond randomness on long range magnetic ordering in the weakly coupled S = 1/2 antiferromagnetic spin chain materials Cu(py)2(Cl1-xBrx)2 is studied by muon spin rotation and bulk measurements. Disorder is found to have a strong effect on the ordering temperature TN, and an even stronger one on the saturation magnetization m0, but considerably more so in the effectively lower-dimensional Br-rich materials. The observed behavior is attributed to Random Singlet ground states of individual spin chains, but remains in contradiction with chain mean field theory predictions. In this context, we discuss the possibility of a universal distribution of ordered moments in the weakly coupled Random Singlet chains model.

Convolutional Compressed Sensing Using Deterministic Sequences

description: In this paper, a new class of circulant matrices built from deterministic sequences is proposed for convolution-based compressed sensing (CS). In contrast to random convolution, the coefficients of the underlying filter are given by the discrete Fourier transform of a deterministic sequence with good autocorrelation. Both uniform recovery and non-uniform recovery of sparse signals are investigated, based on the coherence parameter of the proposed sensing matrices. Many examples of the sequences are investigated, particularly the Frank-Zadoff-Chu (FZC) sequence, the \textit{m}-sequence and the Golay sequence. A salient feature of the proposed sensing matrices is that they can not only handle sparse signals in the time domain, but also those in the frequency and/or or discrete-cosine transform (DCT) domain.

description: Junge Ärzte:innen sowie Pflegende in der stationären Patientenversorgung sind vielseitig belastet und beansprucht. Die Belastungen können dabei mit gravierenden Konsequenzen behaftet sein. Zu bedenken sind vor allem eine reduzierte Gesundheit der betroffenen Ärzte:innen sowie Pflegenden, die mit nachteiligen Effekten auf ihr Leistungsvermögen und letztendlich die von ihnen gewährleistete Patientenversorgung assoziiert sind. Ferner ist eine Verstärkung des Fachkräftemangels zu befürchten. Zusammenhänge (sowie Einflussfaktoren und Interventionen) des Wohlergehens der Mitarbeitenden mit dem der Patienten sollten auch in Deutschland intensiver erforscht und diskutiert werden. So vielseitig wie die Belastungen sind auch Interventionsmöglichkeiten, um dieselben zu verringern. Neben notwendigen großen Reformen im Gesundheitssystem oder der ärztlichen Aus- und Weiterbildung, die Mitarbeitende vor Ort wenig beeinflussen können, gibt es doch einen relevanten Gestaltungsspielraum in Krankenhäusern und deren einzelnen Abteilungen selbst. Hier ist ein strategisches Vorgehen nötig, dass entsprechende langfristige Ziele (z.B. innerhalb einer Gesamtstrategie wie der Strategie Charité 2030) definiert und Maßnahmen zu deren Erreichen konsequent umsetzt und regelmäßig evaluiert. Dafür muss das Rad nicht neu erfunden werden. Best-practice Beispiele aus In- und Ausland sowie konkrete Handreichungen (z.B. der Unfallversicherungen) geben den Rahmen vor. So kann eine (Sicherheits-) Kultur wachsen, die sich an den Bedürfnissen aller Menschen im Gesundheitswesen - Patienten:innen wie Ärzte:innen, Pflegende und aller anderen Berufsgruppen - orientiert und nachhaltige, effektive und gesunde Versorgungsbedingungen ermöglicht. Bei der Gestaltung dieser Bedingungen kommt Ärzten:innen eine besondere Bedeutung zu. Sie üben einen freien Beruf aus. Es gilt für sie, das Wohl der sich ihnen anvertrauenden Patienten:innen, das Wohl anderer Berufsgruppen im Behandlungsteam sowie das eigene Leistungsvermögen gegen die Interessen von Dritten zu verteidigen. Dabei müssen sie sich als Experten mit verschiedenen herausfordernden Rollen im Gesundheitswesen begreifen, die diese Ziele nur gemeinsam mit den anderen Berufsgruppen erreichen können.

$Z_3$ Scalar Singlet Dark Matter

description: We consider the minimal scalar singlet dark matter stabilised by a $Z_3$ symmetry. Due to the cubic term in the scalar potential, semi-annihilations, besides annihilations, contribute to the dark matter relic density. Unlike in the $Z_2$ case, the dark matter spin independent direct detection cross section is no more linked to the annihilation cross section. We study the extrema of the potential and show that a too large cubic term would break the $Z_3$ symmetry spontaneously, implying a lower bound on the direct detection cross section, and allowing the whole parameter space to be tested by XENON1T. In a small region of the parameter space the model can avoid the instability of the standard model vacuum up to the unification scale. If the semi-annihilations are large, however, new physics will be needed at TeV scale because the model becomes non-perturbative. The singlet dark matter mass cannot be lower than 53.8 GeV due to the constraint from Higgs boson decay into dark matter.

description: Purpose: The research in the field of Indigenous peoples and the espousal of their cultural values in the work environment is recognised as being important as a means of overcoming workplace inequities. The purpose of this paper is to examine research about Maori, the Indigenous people of Aotearoa New Zealand that may inform future enterprises for the long-term prosperity of marginalised Indigenous peoples. Design/methodology/approach: This study reviews the literature on unique cultural dynamics of whanau Maori (New Zealand Maori family/community) study practices and the importance of work/home/life balance. Furthermore, it considers strengths-based community enterprises that can lead to sustainable prosperity for Maori. Findings: The review yielded three theoretical principles that explain mana (sociocultural and psychological well-being), which can be generalised across multiple contexts, with the workplace being one of these contexts. These principles of mana create a contextual match with whanau external realities; an experiential match of a mana empowerment framework that transfers to the study context and an interpersonal understanding of being understood and empowered within the study context. Research limitations/implications: The literature review has been limited to research from 2005 onwards and to research that investigates Maori, the Indigenous peoples of Aotearoa New Zealand. Although the review of the literature has these limitations, the review may be of interest to other studies of Indigenous peoples worldwide. Practical implications: The key factors are interwoven, and their importance is considered in relation to the development of positive and supportive environments, which link to job retention, satisfaction and productivity in the workplace for Maori. This, in turn, can have beneficial knock-on effects for not only the New Zealand economy but also more importantly for enhancing sustainable livelihoods for upcoming generations. Social implications: Tied together, these factors are paramount for cultural, social and ecological benefits for nga rangatahi (young Maori adults) and the wider community in the workplace. Originality/value: The literature review’s value and originality derive from a dearth of recent research on supporting nga rangatahi (young Maori adults) for sustainable prosperity.

description: With the Clean Energy for all Europeans legislative package, the European Union (EU) aimed to put consumers “at the heart” of EU energy policy. The recast of the Renewable Energy Directive (RED II) acknowledged the importance of energy communities for the energy transition and introduced new provisions for renewable energy communities (RECs), empowering them to participate in the energy market. This article analyses the progress of transposing and implementing key provisions of the RED II that apply to RECs in nine European countries and focuses on timeliness and completeness of transposition. It comprises both a qualitative and quantitative assessment covering (1) the definition, rights, and market activities of RECs; (2) key elements of enabling frameworks; and (3) consideration of REC specificities in support schemes for renewable energy. The analysis shows considerable variation in transposition performance between the analysed countries. The authors investigate the reasons for this variation and relate them to findings of European implementation and compliance research. Key factors identified include actor-related and capacity-related factors, institutional fit, and characteristics of the RED II itself. Future research in this field needs multi-faceted avenues and should pay particular attention to the influence of national governments and incumbents, not only in the transposition process, but already in upstream policy formulation at the European level.
