description: We identified two optical counterparts of brightest ultraluminous X-ray Sources (ULXs) in galaxies NGC5474 and NGC3627 (M66). The counterparts in Hubble Space Telescope images are very faint, their V magnitudes are 24.7 ($M_V \approx -4.5$) and 25.9 ($M_V \approx -4.2$), respectively. NGC5474 X-1 changes the X-ray flux more than two orders of magnitude, in its bright state it has $L_X \approx 1.6 \times 10^{40}$ erg/s, the spectrum is best fitted by an absorbed power-law model with a photon index $Γ\approx 0.94$. M66 X-1 varies in X-rays with a factor of ~2.5, its maximal luminosity being $2.0 \times 10^{40}$ erg/s with $Γ\approx 1.7$. Optical spectroscopy of the NGC5474 X-1 has shown a blue spectrum, which however was contaminated by a nearby star of 23 mag, but the counterpart has a redder spectrum. Among other objects captured by the slit are a background emission-line galaxy (z=0.359) and a new young cluster of NGC5474. We find that these two ULXs have largest X-ray-to-optical ratios of $L_X/L_{opt}$ ~ 7000 for NGC5474 X-1 (in its bright state) and 8000 for M66 X-1 both with the faintest optical counterparts ever measured. Probably their optical emission originates from the donor star. If they have super-Eddington accretion discs with stellar-mass black holes, they may also have the lowest mass accretion rates among ULXs such as in M81 X-6 and NGC1313 X-1.

description: Die eigentliche, in den verschiedenen Formen der Skandalisierung von "Algorithmisierung" des Rechts und seines Gegenstandsbereichs sich nur unterschiedlich ausformende, durch das Auftreten der neuen digitalen Rechtsakteure aufgetane Problematik, besteht darin, dass die Technik es erschwert, einige funktionalen Fiktionen aufrecht zu erhalten, hinter denen sich die Unentscheidbarkeitsparadoxie verbirgt. Unter dieser Prämisse lautet die soziologische Anschlussfrage weniger, wofür Algorithmen Äquivalente darstellen, als vielmehr, welche Äquivalente zu den klassischen Mechanismen des Verbergens der Fiktionalität sich mit ihrem Aufkommen einspielen. Der vorgeschlagene Ansatz versucht eine Teilantwort auf der Ebene von Semantik. Der Begriff der algorithmic accountability fungiert als einheitliche Lösungsformel für die diversen Folgeprobleme der Entscheidungsparadoxie. Anhand einer Zurückverfolgung der Geschichte der accountability-Semantik werden drei Bedeutungsdimensionen des Begriffs unterschieden, welche allesamt als Antwort auf Fragen nach dem Umgang mit diversen Problemen dienen können, die die vermehrte Beteiligung algorithmischen Entscheidens an der sozialen Welt aufwirft.

description: We describe a minimal extension of the standard model by three right-handed neutrinos, a scalar doublet, and a scalar singlet (the "$ν$DFSZ") which serves as an existence proof that weakly coupled high-scale physics can naturally explain phenomenological shortcomings of the SM. The $ν$DFSZ can explain neutrino masses, baryogenesis, the strong CP problem, and dark matter, and remains calculably natural despite a hierarchy of scales up to $\sim 10^{11}$ GeV. It predicts a SM-like Higgs boson, (maximally) TeV-scale scalar states, intermediate-scale hierarchical leptogenesis ($10^5\text{ GeV}\lesssim M_{N}\lesssim 10^7\text{ GeV}$), and axionic dark matter.

description: This paper presents work in progress from a comparative qualitative analysis of political discourses on the admission or rejection of refugees in different countries around the world. Despite being subject to the norms and principles of international law that require states to open their borders to refugees seeking safety from persecution and serious human rights violations, states differ significantly in terms of their refugee policies and their justifications for these policies. In our project, we compare political discourses on the admission of refugees in different countries. We also try to account for country differences by drawing on the notion of "discursive opportunity structures". We illustrate how different discursive opportunity structures might have shaped the political discourses in two of our six country cases: The Turkish discourse on Syrian refugees and the Chilean discourse on Venezuelan migrants.

description: We prove uniform estimates for the expected value of averages of order statistics of bivariate functions in terms of their largest values by a direct analysis. As an application, uniform estimates for the expected value of averages of order statistics of sequences of independent random variables in terms of Orlicz norms are obtained. In the case where the bivariate functions are matrices, we provide a "minimal" probability space which allows us to $C$-embed certain Orlicz spaces $\ell_M^n$ into $\ell_1^{cn^3}$, $c,C>0$ being absolute constants.
Nutrition Requirements in Patients with Acute Brain Injury Undergoing Pentobarbital Infusion

Year: 2016

description: Pentobarbital infusion can be a treatment intervention to manage acute brain injury patients with refractory increases in intracranial pressure (ICP).  In fact, acute brain injury patients often experience metabolic changes, which result in different nutritional requirements. These considerations are critical since inappropriate nutrition can result in complications such as refeeding syndrome or underfeeding. The purpose of this study was to assess calories received through nutrition feeding for patients with acute brain injury who underwent pentobarbital infusion, compared against predicted nutrition requirements, and evaluate the need for more accurate methods to optimize nutrition regimens.
This is a retrospective cohort study of acute brain injury adult patients admitted to University of North Carolina (UNC) hospital neuroscience Intensive Care Unit (ICU) from May 1, 2010 to August 31, 2013 who underwent pentobarbital infusion for longer than 48 hours and at least 16 years old. Data were collected 48 hours before, during, and 48 hours after pentobarbital infusion.
Eighteen patients were included in the study. The median age was 57 years (Interquartile range, IQR 54 – 63). Patients spent an average of 6.4 days in the pentobarbital phase. Mean total nutrition calories from tube feed for pre-pentobarbital was 1385.4 kcal ± 542.4; during pentobarbital phase was 510.3 kcal ± 317.1; and post-pentobarbital phase was 1021 kcal ± 509. In addition, both Harris-Benedict equation and 25 kcal/kg predicted higher total nutritional calories required for these patients with acute brain injury receiving pentobarbital infusion.

description: Millimeter wave channels suffer from considerable degradation in the channel quality when the signal is Non Line of Sight (NLOS) between the source and the destination. Multihop relaying is thus anticipated to improve the communi- cation between a source and its destination. This is achieved by transmitting the signal to a sequence of relays in which a Line of Sight (LOS) signal exists between two nodes along the path, or more generally when the signal is better than the transmitted signal directly from the source to the destination. In this paper, we consider a millimeter wave network composed of multiple source- destination pairs and a set of deployed relays. We formulate the problem of multihop relaying as a cooperative network formation game in which each relay chooses which source-destination pair to assist in order to improve the end-to-end performance, that is, the multihop delay between the source and the destination. Further, we present an algorithm based on the Nash Bargaining Solution to ensure fairness among the different source-destination pairs and assess its efficiency on numerical simulations.

Cultivating a sense of belonging: examining the effectiveness of the urban male leadership academy scholars program in promoting academic success and serving as an intervention to increase enrollment, retention and graduation rates of Black and Latino male college students
Creators: name: Perez, Kristy Clementina
Publisher: name: No Publisher Supplied
Year: 2023

description: The college enrollment and graduation rates of Black and Latino males continues to be a persistent higher education problem. Furthermore, institutions of higher education fail the interests and educational advancement of Black and Latino men by many measures such as retention and college completion rates. More specifically, institutionalized racism obstructs Black and Latino males from advancing educationally or pushes them out before they even graduate from high school. In higher education, institutional racism manifests itself in admissions policies that appear race-neutral by implementing and relying heavily on standardized tests such as the SAT, which disproportionately excludes historically marginalized communities of color such as Black and Latino males (Garcia, 2019; Figueroa & Garcia, 2006). In 2010, using a more comprehensive admissions process that placed more emphasis on the students’ academic potential and motivation rather than on SAT scores, the Urban Male Leadership Academic Scholars Program was created. The aim was to increase the enrollment, retention, and graduation rates of Black and Latino men in the Percy E. Sutton SEEK Program and Baruch College. The purpose of this qualitative research study was to examine the Urban Male Leadership Academy Scholars students’ experiences and perceptions of the Urban Male Leadership Academy Scholars Program and Baruch College. While applying Critical Race Theory and using sense of belonging as the conceptual framework, the study found that participants viewed their relationship with one another as well as the UMLA facilitators and staff as brothers, a support network and like a family. Participants also shared that UMLA provided a healing, therapeutic & affirming environment, an institutional pathway into the top-tier CUNY four-year college and raised their critical consciousness. The participants also expressed the need to expand the UMLA program. Due to the global pandemic, institutions across the country paused the use of standardized tests scores as a criterion for admissions. This presents an opportunity to end gatekeeping mechanisms that perpetuate institutionalized racism and instead broaden its admissions model. Practitioners, administrators, and policymakers also need to institute Black and Latino Male Initiatives on college campuses based on a CRT and anti-racist framework. Further research on Black and Latino alumni who participated in BMI programs as well as their post-graduation experience is also recommended.
Long-slit spectral observations and stellar mass-to-light ratio of spiral galaxy UGC11919

description: We performed the long-slit observations of spiral galaxy UGC11919 with the Russian 6-m telescope to study its kinematics and stellar population. The previous studies gave basis to suspect that this galaxy possesses a peculiarly low mass-to-light ratio $M/L_B$ of stellar population which could indicate the presence of bottom-light stellar initial mass function (IMF). The ratio $M/L_B$ estimated for different evolutionary models of stellar population using both the broad-band magnitudes and the detailed spectral data confirms this peculiarity if the disc inclination angle $i>30^o$, as it was obtained earlier from the optical photometry, in a good agreement with the HI data cube modelling. However the re-processing of HI data cube we carried out showed that it is compatible with much lower value $i=13^o$ corresponding to the "normal" ratio $M/L_B$, which does not need any peculiar stellar IMF. Stellar velocity dispersion measured at one disc radial scalelength from the center also better agrees with the low disc inclination. However in this case we should admit that the disc possesses a non-axisymmetric shape even after taking into account a two-armed spiral structure. The derived stellar kinematic profiles reveal a signature of kinematically decoupled nuclear disc in the galaxy. Using different evolution models of stellar population we estimated the stellar metallicity [Z/H] (-0.4, -0.5 and -0.3 dex) and the mean luminosity-weighted (for the luminosity in the spectral range $4800-5570$ Å) stellar age (4.2, 2.6 and 2.3 Gyr) for the bulge, disc and nuclear disc of this galaxy respectively.

Codetermination’s Effect on Firm Performance through the Great Recession: A Cross-Country Analysis between Germany and the United Kingdom
Creators: name: Talcott, Charles
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This thesis examines the effects of German codetermination on firm profitability, productivity, employment, and wages. In addition to laying out the theoretical considerations regarding codetermination, this thesis contains a review of the empirical studies of codetermination conducted to date and a unique study comparing German and British firms through the Great Recession (2007–2010) and the recovery thereafter (2011–2014). Using four multiple regression models, I compare a sample of German codetermined firms (n = 71) with a comparable set of British firms (n = 291) that feature no board-level employee representation. The results of the empirical analysis indicate that property rights theorists are incorrect in concluding that codetermination causes firms to underperform. These findings are consistent with the results of previous studies of codetermination. At the end of this thesis, I outline several promising areas for future research on codetermination.

description: We study statistical restricted isometry, a property closely related to sparse signal recovery, of deterministic sensing matrices of size $m \times N$. A matrix is said to have a statistical restricted isometry property (StRIP) of order $k$ if most submatrices with $k$ columns define a near-isometric map of ${\mathbb R}^k$ into ${\mathbb R}^m$. As our main result, we establish sufficient conditions for the StRIP property of a matrix in terms of the mutual coherence and mean square coherence. We show that for many existing deterministic families of sampling matrices, $m=O(k)$ rows suffice for $k$-StRIP, which is an improvement over the known estimates of either $m = Θ(k \log N)$ or $m = Θ(k\log k)$. We also give examples of matrix families that are shown to have the StRIP property using our sufficient conditions.

description: A class of nucleosome remodeling motors translocate nucleosomes, to which they are attached, toward the middle of DNA chain in the presence of ATP during in vitro experiments. Such a biological activity is likely based on a physical mechanism for detecting and comparing the lengths of the flanking polymer chains. Here we propose that a pivoting mode of DNA fluctuation near the surface of the nucleosome coupled with binding reaction with a DNA binding site of the motor provides a physical basis for length detection. Since the mean frequency of fluctuation is higher for a shorter chain than a longer one due to its lower drag coefficient, a shorter chain has a higher rate of receptor binding, which triggers the ATP-dependent activity of the remodeling motor. Dimerization of such units allows the motor to compare the length of the flanking DNA chains, enabling the translocation of the nucleosome toward the center of the DNA.
Music as a treatment for anxiety and/or pain for children during painful procedures: An Integrative Review
Creators: name: Morgan, Leah

Year: 2015

description: Pain is a subjective, unpleasant sensory experience which is formed and exacerbated by previous memories of pain (International Association for the Study of Pain, 1994; Young, 2005). Personal experiences of pain, which can be caused by childhood medical procedures, can be worsened by the presence of anxiety and anxiety can lead to higher reports of pain (Goodenough et al., 1999; Whitehead-Pleaux, Baryza, & Sheridan, 2006). Pain can begin as early as a day old and if the pain goes unattended, it has been associated with lifelong effects including lower pain threshold, PTSD, medical fear, and avoidance of healthcare (Pate, Blount, Cohen, & Smith, 2010; Rennick, Johnston, Dougherty, Platt, & Ritchie, 2002; Taddio, Shah, Gilbert-MacLeod, & Katz, 2008). An integrative review was performed to examine the state of the literature on using music as a treatment for pain and anxiety in children during painful procedures. A search of CINAHL, PubMed, and EMBASE resulted in eight randomized controlled trials involving music as an intervention with a total of 596 children age 0-18 undergoing a painful procedures. In general, music was seen to be a predictor of decreasing pain and/or anxiety during painful procedures. However, due to the heterogeneous nature of the studies it was difficult to draw definitive conclusions. Future research should focus on larger sample sizes and more consistent methods to answer questions of music’s effectiveness.

demonstrated that low-income African American mothers have the lowest breastfeeding
initiation rates in the state (CDC 328). In addition to the spatial distribution of breastfeeding
support networks, I also map the distribution of low-income African American women of
childbearing age across the state of North Carolina and look at the relationship between the
locations of the women alongside the distribution of breastfeeding-friendly facilities to determine
trends that address the cause of low initiation rates.

description: Abstract: The potassium concentration in the extracellular environment is a crucial modulator of neuronal excitability. Recent advances in the technology of ionic actuators are enabling the perturbation of the ionic milieu at the spatiotemporal resolution of neuronal cells and action potentials, thereby holding the promise of making the control of potassium concentration a viable neuromodulation modality. We first introduce a theoretical framework based on bifurcation analysis to inform principled approaches to such neuromodulation strategy. We then propose a hybrid computational framework to couple the circuit-level description of neural membranes with the finite element modeling of ionic transport in cellular fluids and ionic actuators. As case studies, we assume cortical neurons as target cells and PEDOT:PSS-coated electrodes as iontronic transducers (see Fig. on the right). These efforts may shed light on how neural activity can be shaped by targeting extracellular potassium.

We find the different dynamical regimes (soft and hard excitation) to affect the oscillation intensity but not their period. This configuration may permit to implement compact hyper-parametric sources on an integrated optical circuit, with interesting applications in communications, sensing and metrology.

The Functional Connectivity of the Resting Brain in Children With Attention Deficit Hyperactivity Disorder
Creators: name: Guerra, Carina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Attention deficit hyperactivity disorder (ADHD) is a prevalent and detrimental psychiatric disorder that is recently being examined with a distributed network perspective using functional magnetic resonance imaging (fMRI). Specific disruptions in the connections within and in between intrinsic connectivity networks during a resting state have been considered as a way to characterize various psychiatric disorders including ADHD. Disruptions in the within-network connectivity of the default mode network (DMN) as well as in the regulation of the salience network (SAL) have been implicated in the pathophysiology of ADHD. The current study examined these disruptions by performing independent component analyses on the resting state fMRI scans of 13 children with ADHD and 13 age and gender matched neurotypical children. SAL activations were compared between groups to determine whether the SAL was being adequately attenuated in children with ADHD. Our results indicate that the left prefrontal cortical region of the SAL was improperly attenuated, while the left posterior parietal region was overly attenuated during a resting state in children with ADHD compared to controls. Intrinsic connectivity of the DMN was examined using group correlation matrices. Results from this analysis show that some of the connectivities within the DMN exhibited previously determined developmentally delayed trends that highlighted a failure for circuitry to integrate. However, several other connectivities found to be disrupted in the current study in children with ADHD were not connectivities that had been identified by previous literature to be developmentally dynamic. Therefore, these findings provide mixed results that do not unanimously support the maturational delay hypothesis of ADHD. Overall, this study’s findings provide preliminary evidence that state-inappropriate SAL activations and specific connectivity disruptions within the DMN are present during the resting state in children with ADHD.

Island innovation in an era of climate change: Tokelau's moral leadership through renewable energy
Creators: name: Ellsmoor, James

description: Small Island Developing States (SIDS) have become protagonists in the global movement to reduce
greenhouse gas emissions by calling upon their extreme environmental vulnerability to situate
themselves as leaders in the fight against climate change. At international climate conventions, SIDS
have captured the imagination of the public worldwide by demonstrating the real impacts of climate
change in an accelerated timeframe. The prevailing wisdom dictates that SIDS are non-competitive in
entrepreneurship, yet these small nations have become global leaders in both mitigating their
contributions to greenhouse gas emissions and adapting to the effects of climate change. By engaging
in policy innovation, many islands have been able to turn their constraints to their advantage to situate
themselves as global leaders in knowledge production for climate change adaptation. Yet, how might
innovation be characterized in the context of climate change? This study approaches this question
using the case of the Pacific island territory of Tokelau, which has a population of less than 1,500, and
yet became a global leader in climate debates by generating almost all of its electricity with solar
photovoltaic panels. As an extremely isolated and recently depopulated territory, Tokelau had major
constraints to developing such a project. This study identifies creative indigenous thinking and
engagement with its political status as a sub-national island jurisdiction (SNIJ) of New Zealand as
island innovations that enabled Tokelau at once to enact the groundbreaking Tokelau Renewable
Energy Project and couple it with a move towards moral leadership in global climate politics. These
finding reveals that SNIJs and SIDS can turn their perceived disadvantages as small and isolate states
into engines of innovation that create a significant impact within and well beyond their own shores.
title: Die Tragödie der Kultur als Tragödie der Soziologie oder wie die Soziologie das Menschliche aus dem Blick zu verlieren droht: Anmerkungen zu einer fatalen Entwicklung

description: Kulturen sind Konkretheiten, Sinneinheiten in der "Fülle" der Geschichte, vom Menschen geschaffen zur Verwirklichung des mit ihm gegebenen Versprechens. Diese Bestimmung von Kultur stammt von Johann Gottfried Herder und gilt ebenso für Georg Simmel. Bei Simmel tritt indes das Tragische der Kultur hervor. Kultur ist der Inbegriff einer Bewegung: des zu sich selbst Findens der menschlichen Seele. Doch ihr Weg führt durch die 'Sphäre' des "Geistes". Kunst, Recht, Religion, Technik, Wissenschaft, Sitte - in ihnen hat der Geist eine "beharrende Existenz gewonnen"; und in ihnen, nach der ihnen eigenen sachlichen Ordnung, werden die Bewegungen der Seele fortan "gesammelt" und gelenkt. Durch das "Gefüge der Kultur" verläuft mithin ein "Spalt" und die "Idee der Kultur" verliert ihre "Heimat". Der Mensch "läuft Gefahr, von seiner eigenen Schöpfung erschlagen zu werden". Was bei Georg Simmel vorgezeichnet ist, wird bei Alfred Weber explizit Thema: Die Tragödie der Kultur ist auch die Tragödie der Wissenschaft - und dementsprechend auch der Soziologie. Die Tragödie der Soziologie ist eine zweifache: Zum einen ist die Soziologie angewiesen auf ihre immanente Ordnung, auf ihre Begriffe und Denkfiguren. Die sozialen und kulturellen Lebensformen sind jedoch mehr als der Soziologie durch ihre Betrachtungsweise vermittelt wird. Was die Soziologie sieht, sind die "Ausdrucksseiten" und "Ausdrucksarten" der Kultur, nicht die kulturellen Universalien selbst. Das ist ihr Schicksal. Zum anderen läuft die Soziologie Gefahr, sich 'ihrer Sache', und letztlich sich selbst, zu entfremden - dann, wenn der Rationalisierungsprozess, welcher ihr Denken zusehends durchsetzt, mit all den Formen und Prinzipien, die ihn 'ausmachen', Realitätscharakter annimmt. Eingeschlossen in die "beharrende Existenz" ihres eigenen Denkens droht die Soziologie die Bewegungen der Seele und mithin das Menschliche gänzlich aus dem Blick zu verlieren; und der Weg zu den Hyperrealitäten von Jean Baudrillard ist nicht mehr weit. Was den zweiten Teil der Tragödie angeht, hält die Soziologie ihr Schicksal indes in den eigenen Händen. Ideengeschichtliche Aufklärung hilft ihr, dies zu erkennen.

description: In this paper we determine the phase diagrams (for $T=0$ as well as $T>0$) of the Penson-Kolb-Hubbard model for two dimensional square lattice within Hartree-Fock mean-field theory focusing on investigation of superconducting phases and possibility of the occurrence of the phase separation. We obtain that the phase separation, which is a state of coexistence of two different superconducting phases (with $s$-wave and $η$-wave symmetries), occurs in define range of the electron concentration. In addition, increasing temperature can change the symmetry of the superconducting order parameter (from $η$-wave into $s$-wave). The system considered exhibits also an interesting multicritical behaviour including bicritical points.

description: Starting from a Su-Schrieffer-Heeger-like model inferred from first-principles simulations, we show that the metal-insulator transition in In/Si(111) is a first-order grand canonical Peierls transition in which the substrate acts as an electron reservoir for the wires. This model explains naturally the existence of a metastable metallic phase over a wide temperature range below the critical temperature and the sensitivity of the transition to doping. Raman scattering experiments corroborate the softening of the two Peierls deformation modes close to the transition.

description: One view of the solar-wind turbulence is that the observed highly anisotropic fluctuations at spatial scales near the proton inertial length $d_p$ may be considered as Kinetic Alfvén waves (KAWs). In the present paper, we show how phase-mixing of large-scale parallel propagating Alfvén waves is an efficient mechanism for the production of KAWs at wavelengths close to $d_p$ and at large propagation angle with respect to the magnetic field. Magnetohydrodynamic (MHD), Hall-Magnetohydrodynamic (HMHD), and hybrid Vlasov-Maxwell (HVM) simulations modeling the propagation of Alfvén waves in inhomogeneous plasmas are performed. In linear regime, the role of dispersive effects is singled out by comparing MHD and HMHD results. Fluctuations produced by phase-mixing are identified as KAWs through a comparison of polarization of magnetic fluctuations and wave group velocity with analytical linear predictions. In the nonlinear regime, comparison of HMHD and HVM simulations allows to point out the role of kinetic effects in shaping the proton distribution function. We observe generation of temperature anisotropy with respect to the local magnetic field and production of field-aligned beams. The regions where the proton distribution function highly departs from thermal equilibrium are located inside the shear layers, where the KAWs are excited, this suggesting that the distortions of the proton distribution are driven by a resonant interaction of protons with KAW fluctuations. Our results are relevant in configurations where magnetic field inhomogeneities are present, as, for example, in the solar corona where the presence of Alfvén waves has been ascertained.
Bound by the Care We’ve Learned to Receive: The Persistence of Adolescent Health and Dental Care Utilization Behaviors into Young Adulthood

description: The transition from adolescence to young adulthood, though often considered a period of newfound independence and freedom, is characterized by worsening health and decreased health and dental care utilization, especially among males. To further understand the factors that shape health and dental care utilization during young adulthood, this study examines the socioeconomic stratification of adolescent health and dental care utilization behaviors, the impact of these behaviors during adolescence on health and dental care utilization during young adulthood, and the modifying effects of gender on utilization across the transition to young adulthood. Controlling for disparate levels of access and need, I use multivariate logistic regressions to analyze data from Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health. I find that lower parental educational attainment and income are significantly associated with lower odds of care during adolescence. My results also reveal the persistence of adolescent utilization behaviors into young adulthood, but gender is not related to the endurance of such behaviors. Among other theories, I integrate the life course perspective into the Behavioral Model of Health Services Use to explain my findings and make a call for improvements in social and health care policies to prevent the further stratification of health and dental care use, as well as the persistence of poor utilization behaviors into young adulthood.
Learning on Graphs: Supervised and Unsupervised Methods

description: We study two methods for learning from network graph data. First, we present a novel method for the unsupervised learning problem of community detection. The proposed method is, to the best of our knowledge, the first enabling users to "zoom in" and "zoom out" on communities with varying levels of focus on network metadata. Second, we review Decagon, a system proposed by Zitnik et al. for the supervised learning task of link prediction. On a biomedical benchmark dataset, Decagon achieves state-of-the-art prediction accuracy. This work adds to the network scientist's machine learning toolkit, illustrating its power in a biomedical domain with significant public health impact.

description: We consider weak solutions for a diffuse interface model of two non-Newtonian viscous, incompressible fluids of power-law type in the case of different densities in a bounded, sufficiently smooth domain. This leads to a coupled system of a nonhomogenouos generalized Navier-Stokes system and a Cahn-Hilliard equation. For the Cahn-Hilliard part a smooth free energy density and a constant, positive mobility is assumed. Using the $L^\infty$-truncation method we prove existence of weak solutions for a power-law exponent $p>\frac{2d+2}{d+2}$, $d=2,3$.
