Year: 2022
Subjects: economics

description: State and local policies increasingly restrict access to job applicants’ criminal records, but without addressing the underlying reasons that employers conduct criminal background checks. Employers may thus still ask about an applicant’s criminal record later in the hiring process or make inaccurate judgments about an applicant’s criminal record based on demographic characteristics. In this paper, we use a field experiment conducted in partnership with a nationwide staffing platform to test a range of alternative policies that more directly address the reasons that employers may conduct criminal background checks. The experiment asked hiring managers at nearly a thousand U.S. businesses to make actual hiring decisions under different randomized conditions. We find that 39% of businesses in our sample are willing to work with workers with a criminal record at baseline, which rises to over 50% when businesses are offered crime and safety insurance, a single performance review, a background check covering just the past year, or objective information on the productivity of these workers. Wage subsidies can achieve similar increases but at a substantially higher cost. Based on our findings, the staffing platform modified its user interface to relax the criminal background check requirement and offer crime and safety insurance.

description: Future Communication networks are tending towards a diverse wireless networking world where the positioning information (PI) could be helpful in different techniques like the dynamic resource allocation. On the other hand, the PI could be widely used for cooperative techniques in the relay and/or routing selection process. In this paper, we propose to use the PI in the selection of the relays and then to apply an efficient double layer distributed space time block code (DLSTBC) scheme between the different relays. Using the amplify and forward (AF) technique, we show that the proposed code is very efficient whatever the transmitted power is. Moreover, we show that the relay selection process based on PI yields very powerful results when compared to the random relay selection (RS) process

Does Saving Cause Borrowing?

Subjects: savings nudges

description: We study whether or not nudging individuals to save more has the unintended consequence of additional borrowing in high-interest unsecured consumer credit. We analyze the effects of a large-scale experiment in which 3.1 million bank customers were nudged to save more via (bi-)weekly SMS and ATM messages. Using Machine Learning methods for causal inference, we build a score to sort individuals according to their predicted treatment effect. We then focus on the individuals in the top quartile of the distribution of predicted treatment effects who have a credit card and were paying interest at baseline. Relative to their control, this group increased their savings by 5.7% on average or 61.84 USD per month. At the same time, we can rule out increases in credit card interest larger than 1.25 USD with 95% statistical confidence. We thus estimate that for every additional dollar of savings, individuals incur less than 2 cents in additional borrowing cost. This is a direct test test of the predictions of rational co-holding models, and is an important result to evaluate policy proposals to increase savings via nudges or more forceful measures.
On the large-scale instability in interacting dark energy and dark matter fluids

description: Recently, Valiviita et al. (2008) have reported a large-scale early-time instability in coupled dark energy and dark matter models. We take the same form of energy-momentum exchange and specialise to the case when the interaction rate is proportional to Hubble's parameter and the dark energy density only. Provided the coupling is made small enough for a given equation of state parameter, we show that the instability can be avoided. Expressions are derived for non-adiabatic modes on super-horizon scales in both the radiation and matter dominated regimes. We also examine the growth of dark matter perturbations in the sub-horizon limit. There we find that the coupling has almost no effect upon the growth of structure before dark energy begins to dominate. Once the universe begins to accelerate, the relative dark matter density fluctuations not only cease to grow as in uncoupled models, but actually decay as the universe continues to expand.

Bei "Wiarda wundert sich" treffen sie sich zur Wahldebatte. AM 9. MAI wird er gewählt, der neue Chefrepräsentant der deutschen Hochschulen, doch ein öffentliches Aufeinandertreffen vorab war nicht geplant. Schade, dachte ich. Denn wer HRK-Präsident wird, ist nicht nur für die wahlberechtigten Hochschulleitungen von Bedeutung, sondern auch für alle anderen an den Hochschulen. Macht er seinen Job gut, prägt der Neue die wissenschaftspolitischen Debatten entscheidend mit. Zwei Männer, zwei in Westdeutschland aufgewachsene Präsidenten mittelgroßer ostdeutscher Universitäten, sind die Kandidaten, die ins Rennen gehen. Sie müssen aber die Vielfalt der Hochschulen und Menschen, die dort arbeiten, vertreten. Wie kann das gelingen? Was ist die HRK, was sollte sie ein, und für wen spricht sie? Das ist nur eine der Fragen, die ich den beiden gestellt habe: dem Wirtschaftsinformatiker Oliver Günther, seit 2012 Präsident der Universität Potsdam, und den Mediziner und Pharmakologe Walter Rosenthal, der seit 2014 die Friedrich-Schiller-Universität Jena leitet. Außerdem wollte ich wissen, wie zwei Unipräsidenten die Kluft zwischen Universitäten und Hochschulen für angewandte Wissenschaft in der HRK überwinden wollen, wie ihre Lösung für die Novelle des Wissenschaftszeitvertragsgesetzes aussähe – und welche Schlussfolgerungen sie aus den neuerdings sinkenden Studierendenzahlen ziehen. Und schließlich habe ich sie gefragt, wie sie die Forschungs- und Innovationspolitik der Bundesregierung beurteilen – und welche Veränderungen sie erreichen wollen. Wer Streit zwischen den beiden erwartet, wird weitgehend enttäuscht. Mehr nach innen und außen kommunizieren wollen sie beide. Aber beim genauen Hinhören zeigen sich dann doch die Unterschiede. Vor allem für jene, die nicht wahlberechtigt sind, könnten sie entscheidend sein.

description: We study the frictions in dealer-intermediation in residential real estate through the lens of “iBuyers,” technology entrants, who purchase and sell residential real estate through online platforms. iBuyers supply liquidity to households by allowing them to avoid a lengthy sale process. They sell houses quickly and earn a 5% spread. Their prices are well explained by a simple hedonic model, consistent with their use of algorithmic pricing. iBuyers choose to intermediate in markets that are liquid and in which automated valuation models have low pricing error. These facts suggest that iBuyers’ speedy offers come at the cost of information loss concerning house attributes that are difficult to capture in an algorithm, resulting in adverse selection. We calibrate a dynamic structural search model with adverse selection to understand the economic forces underlying the tradeoffs of dealer intermediation in this market. The model reveals the central tradeoff to intermediating in residential real estate. To provide valuable liquidity service, transactions must be closed quickly. Yet, the intermediary must also be able to price houses precisely to avoid adverse selection, which is difficult to accomplish quickly. Low underlying liquidity exacerbates adverse selection. Our analysis suggests that iBuyers’ technology provides a middle ground: they can transact quickly limiting information loss. Even with this technology, intermediation is only profitable in the most liquid and easy to value houses. Therefore, iBuyers’ technology allows them to supply liquidity, but only in pockets where it is least valuable. We also find limited scope for dealer intermediation even with improved pricing technology, suggesting that underlying liquidity will be an impediment for intermediation in the future.
Property-Tax-Induced Mobility and Redistribution: Evidence from Mass Reappraisals

description: I investigate the effect of property tax changes on individual homeowner mobility and voted tax rates using a panel of individual assessment and sales records in Ohio. I use regulatory stabilization rules that cause changes in individual taxes with no mechanical change in quantity of public goods to examine how changes in a homeowner's tax bill influence sales, foreclosure events, and home equity loan origination. The changes in taxes I observe are driven by changes in relative assessment growth within school districts and allow me to identify the effects of changes in taxes separately from the effects of changing housing wealth. Using a leave-one-out by county random forest regression on assessed values to instrument for tax changes, I find that a $0.10 increase in the price per dollar of services leads to a 5% increase in the likelihood of sale with no change in the likelihood of foreclosure. I also find suggestive evidence of increased voted tax rates at the school district level when the ratio of median to mean taxable value decreases.

description: Public goods provided by local governments shape many fundamental aspects of life, such as access to education, safety, and neighborhood quality. But how much households value publicly provided goods compared to neighborhood amenities remains unclear. This paper uses a sample of 1.5 million houses in thousands of neighborhoods that straddle local government boundaries to isolate local government valuation. We find that households value access to specific local governments even when comparing homes on opposite sides of the same street but in different governments, suggesting an important role for excludable local public goods. White and Black households show little differential valuation, while Hispanic and especially Asian households exhibit lower and higher valuation, respectively. Local government valuation is mediated through the quality of schooling, free-riding on high-property tax payers, and the quality of peers with whom public goods are consumed.

description: Although the astronomy community is witnessing an era of large telescopes, smaller and medium sized telescopes still maintain their utility being larger in numbers. In order to obtain better scientific outputs it is necessary to incorporate modern and advanced technologies to the back-end instruments and to their interfaces with the telescopes through various control processes. However often tight financial constraints on the smaller and medium size observatories limit the scope and utility of these systems. Most of the time for every new development on the telescope the back-end control systems are required to be built from scratch leading to high costs and efforts. Therefore a simple, low cost control system for small and medium size observatory needs to be developed to minimize the cost and efforts while going for the expansion of the observatory. Here we report on the development of a modern, multipurpose instrument control system UNICS (Unified Instrument Control System) to integrate the controls of various instruments and devices mounted on the telescope. UNICS consists of an embedded hardware unit called Common Control Unit (CCU) and Linux based data acquisition and User Interface. The Hardware of the CCU is built around the Atmel make ATmega 128 micro-controller and is designed with a back-plane, Master Slave architecture. The Graphical User Interface (GUI) has been developed based on QT and the back end application software is based on C/C++. UNICS provides feedback mechanisms which give the operator a good visibility and a quick-look display of the status and modes of instruments. UNICS is being used for regular science observations since March 2008 on 2m, f/10 IUCAA Telescope located at Girawali, Pune India.

description: Bank liabilities include debt with long-term maturities and deposits that typically are not withdrawn for extended periods. This subjects bank liabilities to debt dilution. Our analysis shows that this has major effects for how monetary policy shocks are transmitted to banks and for optimal capital regulation. Interest rate cuts produce protracted increases in bank risk which are stronger in low-rate regimes. Capital regulation addresses debt dilution but is subject to a time-inconsistency problem. We compare Ramsey and Markov-perfect optimal policies and find that regulator commitment significantly impacts optimal bank capital regulation, sometimes in unexpected ways.

description: Notre intention, dans cette these, est d'examiner par une analyse interne le degre de coherence artistique qui existe aux niveaux symboliques, thematiques et structuraux dans Le Jour est noir de Marie-Claire Blais. A cette fin, nous nous servirons de trois methodes critiques: critique phenomenologique, critique thematique et critique structurale. Le premier chapitre etudie la symbolique du temps selon une methode phenomenologique. Dans le roman, les images qui se referent a l'eau constituent l'expression centrale du temps, formant un reseau temporel et spatial qui symbolise le passe, le present et l'avenir des person-nages. L'Eau est evoquee sous plusieurs aspects: la mer, la riviere, le brouillard et la neige. Leurs nuances symboliques seront examinees. Le deuxieme chapitre etudie la thematique de l'a-lienation. Deux niveaux d'alienation sont decrits: une alienation relative et une alienation absolue. Le troisieme chapitre examine la structure interieure du roman a la lumiere des observations de Claude Bremond sur la structure des oeuvres romanesques parues dans son article "La Logique des possibles narratifs."

description: To gain the run parameters of the combined process of coagulation/in situ chlorination/ultrafiltration (UF) so that the system can remove as much organic contaminants as possible without serious membrane fouling, the impacts of operation conditions in coagulation and pre-chlorination unit were investigated in a pilot-scale test. The characteristics of organics in UF influent were examined by excitation emission matrix spectroscopy to find out fouling behavior of different natural organic matter compositions to UF membrane. Thereafter, the operation parameters of different processing units of the hybrid device were optimized by response surface methodology (RSM). The results showed that the tests with the agitation speed of 40 r min−1 had the lowest membrane fouling rate and the highest CODMn removal, in addition, inappropriate dosage of sodium hypochlorite in membrane influent might exert negative impacts on membrane by lowering UV254 rejection, especially during the high algae laden period. The predominant factors of membrane fouling were the existence of tryptophan protein-like substances and the soluble microbial products. Optimum values of the mechanical rotation speed in coagulation unit, chemical dosage in pre-chlorination unit, and membrane flux in UF unit of the integrative process were 41.79 r min−1, 1.40 mg L−1, and 82.26 LMH, respectively.

description: Spin ensembles play a pivotal role in various quantum applications such as metrology and simulating many-body physics. Recent research has proposed utilizing spin cat states to encode logical quantum information, with logical lifetimes potentially on the order of seconds, achieved via enhanced collective interactions that scale with system size. We investigate the dynamics of spin cat states under inhomogeneous broadening, revealing a phenomenon termed 'parity-sensitive inhomogeneous dephasing': for small amplitudes, odd cat states are significantly more susceptible to inhomogeneous dephasing compared to even cat states due to the difference in parity symmetry. This discrepancy between even and odd cat states vanishes at large amplitudes, and behave similarly to a spin coherent state with the same amplitude. To analyze the stability of the spin coherent state, we perform a mean-field analysis of the driven-dissipative dynamics, from which we identify a synchronization phase transition wherein the ensemble becomes completely dephased beyond a critical inhomogeneous linewidth. The mean-field analysis suggests that the dissipative stabilization can suppress the decoherence effects from inhomogeneous broadening. We argue that the stability of the mean-field model provides a reasonable estimate for that of spin cat states with a large amplitude in the full quantum model. Our findings shed light on the stability of collective spin states, important for advancing quantum technologies.

Simultaneous X-ray/optical/UV snapshots of active galactic nuclei from XMM-Newton: spectral energy distributions for the reverberation mapped sample

description: We employ contemporaneous optical, UV and X-ray observations from the XMM-Newton EPIC-pn and Optical Monitor (OM) archives to present, for the first time, simultaneous spectral energy distributions (SEDs) for the majority of the Peterson et al. (2004) reverberation mapped sample of active galactic nuclei (AGN). The raw data were reduced using the latest pipelines and are all analysed consistently. The virial mass estimates from Peterson et al. (2004) allow us to calculate Eddington ratios lambda_Edd for the sample using the bolometric accretion luminosities determined directly from the SEDs. We calculate hard X-ray bolometric corrections kappa_2-10keV for the sample and confirm a trend for increasing bolometric correction with Eddington ratio proposed in previous studies. Our comparison with previous work on these objects suggests that the OM bandpass may be less susceptible to intrinsic reddening than the far-UV peak of the thermal disc spectrum in AGN, yielding larger bolometric corrections than previous work: kappa_2-10keV ~ 15 - 30 for lambda_Edd ~ 0.2, but part of this increase could be attributed to spectral complexity preventing accurate recovery of the intrinsic luminosity in some sources. Long-term optical-UV variability contributes a second-order, but significant change to the total bolometric luminosity when comparing multiple observations for individual objects.We also consider the effect of a recently proposed correction for radiation pressure when determining black hole masses with reverberation mapping, and find that the revised mass estimates do not significantly alter the range of bolometric corrections seen but may yield a narrower distribution of Eddington ratios.

description: We study the renormalizable quantum gravity formulated as a perturbed theory from conformal field theory (CFT) on the basis of conformal gravity in four dimensions. The conformal mode in the metric field is managed non-perturbatively without introducing its own coupling constant so that conformal symmetry becomes exact quantum mechanically as a part of diffeomorphism invariance. The traceless tensor mode is handled in the perturbation with a dimensionless coupling constant indicating asymptotic freedom, which measures a degree of deviation from CFT. There are no massive ghosts because they are not gauge invariant in this formulation. Higher order renormalization is carried out using dimensional regularization, in which the Wess-Zumino integrability condition is applied to reduce indefiniteness existing in higher-derivative actions. The effective action of quantum gravity improved by renormalization group is obtained. We then make clear that conformal anomalies are indispensable quantities to preserve diffeomorphism invariance. Anomalous scaling dimensions of the cosmological constant and the Planck mass are calculated. The effective cosmological constant is obtained in the large number limit of matter fields.

description: Cosmological constant behavior can be realized as solutions of the Dirac-Born-Infeld (DBI) action within Type IIB string theory and the AdS/CFT correspondence. We derive a family of attractor solutions to the cosmological constant that arise purely from the "relativistic" nature of the DBI action without an explicit false vacuum energy. We also find attractor solutions with values of the equation of state near but with $w\ne-1$; the forms for the potential arising from flux interactions are renormalizable and natural, and the D3-brane tension can be given by the standard throat form. We discuss present and future observational constraints on the theory.

description: The discovery of the Higgs boson has led to new possible signatures for heavy resonance searches at the LHC. Since then, search channels including at least one Higgs boson plus another particle have formed an important part of the program of new physics searches. In this report, the status of these searches by the CMS Collaboration is reviewed. Searches are discussed for resonances decaying to two Higgs bosons, a Higgs and a vector boson, or a Higgs boson and another new resonance. All analyses use proton-proton collision data collected at $\sqrt{s}$ = 13 TeV in the years 2016-2018. A combination of the results of these searches is presented together with constraints on different beyond-the-standard model scenarios, including scenarios with extended Higgs sectors, heavy vector bosons and extra dimensions. Studies are shown for the first time by CMS on the validity of the narrow-width approximation in searches for the resonant production of a pair of Higgs bosons. The potential for a discovery at the High Luminosity LHC is also discussed.

Descent into the abyss of the unconscious : a Jungian approach to E.T.A. Hoffmann and Fyodor Dostoevsky
Creators: name: Loy, Coral Pauline Stenmark
Publisher: name: University of British Columbia
Year: 2011

description: The mythological writings of C.G. Jung provide the basis for a comparative study of two nineteenth-century authors — E.T.A. Hoffmann and Fyodor Dostoevsky. The hero myth is the main interpretive tool, although other aspects of Jungian theory are also included in order to expand the concept of psychic growth. The introductory section sets forth Jung's basic ideas, as well as those of his follower, Erich Neumann. The second chapter offers an analysis of Hoffmann's Der Sandmann. The traumatic experience of the young Nathanael is shown to be the original projection of his psychic dilemma. His development is characterized by a feeling of impotence, as manifest in his fear of losing his eyes. This psychic impotence finally wins the struggle for control when Nathanael commits suicide. Crime and Punishment is also examined in light of the hero myth. Raskolnikov's crime is discussed as a psychic necessity, shifting his motivation from his outer deprivation to his inner impotence. He, too, is plagued by threatening archetypes, but unlike Nathanael he is able to overcome them; he finally recognizes his psychic situation and through this recognition draws closer to a state of psychic wholeness. The final chapter explores the advantages and disadvantages of a Jungian approach to literature, as seen in the analyses of the two works.

description: As in previous years, including 2023, a major focus in the neurooncological area of neuropathology was put on more precise and constantly faster diagnostic procedures, even reaching the level of ultra-fast intraoperative diagnostics based on methylation profiling. Neuropathological diagnostic precision and clinical follow-up treatment has been further increased by combining DNA methylation profiling with targeted panel sequencing. A few new, molecularly defined tumor subtypes have been proposed, among others, a glioneuronal tumor with ATRX alteration, kinase fusion and anaplastic features (in its abbreviated form named GTAKA) and the de novo replication repair deficient glioblastoma, IDH-wildtype both having either distinct prognostic or therapeutic implications. Regarding the understanding of brain tumor development and progression, several novel mechanisms have been presented which might also be considered as treatment targets in the future, such as a) autonomous rhythmical Ca2+ oscillations in interconnected glioma cell networks driving tumor growth; b) transfer of mitochondria from normal astrocytes to glioma cells enhancing proliferation and self-renewal; c) brain endothelial cell remodeling upon matrix-metalloprotease 9 secretion by tumor cells metastasizing into the CNS and d) anti-tumor activity of microglia in CNS metastasis of breast cancer. Finally, in contrast to previous years, several very promising neurooncological treatment studies have been conducted, focusing on specific targets such as H3K27M or IDH1/2 mutations for which a proper neuropathological assessment is key. The continuous translation of potential new treatment targets using faster and precise diagnostic procedures will further pave the way for better individualized clinical care of neurooncological patients.

description: Modeling and prediction of H2S emission from wastewater are important since gaseous H2S will induce significant corrosion and odor problems. Most previous studies focused on H2S emission of wastewater in pipeline systems, which may not be fit for H2S emission in wastewater treatment plants (WWTPs). This study provided a two-phase mass transfer model for prediction of H2S emission concentrations. The model is based on the mass transfer rate equation of the mass transfer impetus, expressed by the concentration difference. The main parameters of the model are the mass transfer coefficient, the carrier gas flow rate and the concentration of H2S in liquid phase. The results showed that the model can simulate and predict H2S emission concentrations of various processes in WWTPs. Moreover, the model can analyze and predict the influences of different pH values, mass transfer coefficients and carrier gas flow rates on H2S emission concentrations and loads. Therefore, the model provides theoretical guidance for design of WWTPs regarding H2S emissions. Implications: Modeling and prediction of H2S emission from wastewater are quite important since gaseous H2S will induce significant corrosion and odor problems. Most of previous studies are focused on H2S emission from wastewater in pipeline system, which may not be fit for H2S emission in wastewater treatment plants (WWTPs). Thus in this study, a model for predicting H2S emission from typical units of WWTPs is established and verified. Moreover, the influences of pH values, mass transfer coefficients and carrier gas flow rates on H2S emission are analyzed. The model can be a useful tool to predict the H2S concentration in odor gas collection system of WWTP and understand the behaviors of H2S emission under different WWTPs operating conditions.

description: We present an interesting monogamy equation for $(2 \otimes 2 \otimes n)$-dimensional pure states, by which a quantity is found to characterize the tripartite entanglement with the GHZ type and W typeentanglements as a whole. In particular, we, for the first time, reveals that for any quantum state of a pair of qubits, the difference between the two remarkable entanglement measures, concurrence and negativity, characterizes the W type entanglement of tripartite pure states with the two-qubit state as reduced density.

description: The analysis of debris disk observations is often based on the assumption of a dust phase composed of compact spherical grains consisting of astronomical silicate. Instead, observations indicate the existence of water ice in debris disks. We quantify the impact of water ice as a potential grain constituent in debris disks on the disk parameter values estimated from photometric and spatially resolved observations in the mid- and far-infrared. We simulated photometric measurements and radial profiles of debris disks containing water ice and analyzed them by applying a disk model purely consisting of astronomical silicate. Subsequently, we quantified the deviations between the derived and the true parameter values. As stars in central positions we discuss a $β$ Pic sibling and main-sequence stars with spectral types ranging from A0 to K5. To simulate observable quantities we employed selected observational scenarios regarding the choice of wavelengths and instrument characteristics. For the $β$ Pic stellar model and ice fractions $\geq 50\ \%$ the derived inner disk radius is biased by ice sublimation toward higher values. However, the derived slope of the radial density profile is mostly unaffected. Along with an increasing ice fraction, the slope of the grain size distribution is overestimated by up to a median factor of $\sim 1.2$ for an ice fraction of $90\ \%$ while the total disk mass is underestimated by a factor of $\sim 0.4$. The reliability of the derived minimum grain size strongly depends on the spectral type of the central star. For an A0-type star the minimum grain size can be underestimated by a factor of $\sim 0.2$, while for solar-like stars it is overestimated by up to a factor of $\sim 4 - 5$. Neglecting radial profile measurements and using solely photometric measurements, the factor of overestimation increases for solar-like stars up to $\sim 7 - 14$.

description: As lesões perfurocontusas por arma de fogo (PAF) apresentam características distintas entre as feridas de entrada e saída, fornecendo informações cruciais para a investigação forense e o tratamento médico. Trauma em região da face, tem sido cada vez mais comum devido a crescente na violência urbana ultimamente. Com isso, as lesões maxilofaciais causadas por arma de fogo têm se tornado rotina nos hospitais de emergência representando um grave problema de saúde pública. O tratamento dos ferimentos penetrantes em face é um desafio em consequência do difícil acesso, comprometimento de estruturas nobres, e risco de fatalidade. Em região de infraorbitária direita causando edema, lesão perfuro-contusa em região malar direita, acuidade visual, motricidade ocular extrínseca de supraversão e infraversão prejudicadas e exoftalmia do olho direito, sendo estabelecido um tratamento em conjunto entre as especialidades de cirurgia e traumatologia bucomaxilofacial e oftalmologia, para remoção do artefato, desbridamento local, remoção de tecido granulomatoso e síntese da conjuntiva ocular e tecidual. Diante do caso clínico apresentado, nota-se que os pacientes com ferimentos por arma de fogo em regiões maxilofaciais, devem ser avaliados por uma equipe multiprofissional, dando ênfase à diminuição das sequelas funcionais e estéticas e às taxas de morbimortalidade. Geralmente maior e mais irregular que a ferida de entrada, com bordas evertidas (viradas para fora). Pode apresentar lacerações e fraturas ósseas, devido à deformação do projétil ao atravessar os tecidos. É de comum pedir uma tomografia para definir uma conduta médica segura e aplicada.

description: Precise radial velocity measurements from HIRES on the Keck I telescope are presented for 40 stars in the outer halo globular cluster NGC 2419. These data are used to probe the cluster's stellar mass function and search for the presence of dark matter in this cluster. NGC 2419 is one of the best Galactic globular clusters for such a study due to its long relaxation time (T_{r0} ~ 10^{10} yr) and large Galactocentric distance (R_{GC} ~ 90 kpc) -- properties that make significant evolutionary changes in the low-mass end of the cluster mass function unlikely. We find a mean cluster velocity of =-20.3 +- 0.7 km/sec and an internal velocity dispersion of σ= 4.14 +- 0.48 km/sec, leading to a total mass of (9.0 +- 2.2) * 10^5 Msun and a global mass-to-light ratio of M/L_V = 2.05 +- 0.50 in solar units. This mass-to-light ratio is in good agreement with what one would expect for a pure stellar system following a standard mass function at the metallicity of NGC 2419. In addition, the mass-to-light ratio does not appear to rise towards the outer parts of the cluster. Our measurements therefore rule out the presence of a dark matter halo with mass larger than ~10^7 Msun inside the central 500 pc, which is lower than what is found for the central dark matter densities of dSph galaxies. We also discuss the relevance of our measurements for alternative gravitational theories such as MOND, and for possible formation scenarios of ultra-compact dwarf galaxies.

Why haven't the observed high-frequency QPOs been produced by (MHD) computer simulations of black hole accretion disks?

description: We compare some predictions of Wagoner & Tandon (2021) with the results of the hydrodynamic and magnetohydrodynamic (MHD) simulations of Reynolds & Miller (2009). It appears that the MHD simulations were not run for long enough and the numerical damping was not small enough to produce the observed high-frequency QPOs (and the g-mode seen in the hydro simulations).
