description: The Milky Way halo was predominantly formed by the merging of numerous progenitor galaxies. However, our knowledge of this process is still incomplete, especially in regard to the total number of mergers, their global dynamical properties and their contribution to the stellar population of the Galactic halo. Here, we uncover the Milky Way mergers by detecting groupings of globular clusters, stellar streams and satellite galaxies in action ($\mathbf{J}$) space. While actions fully characterize the orbits, we additionally use the redundant information on their energy ($\textit{E}$) to enhance the contrast between groupings. For this endeavour, we use $\textit{Gaia}$ EDR3 based measurements of $170$ globular clusters, $41$ streams and $46$ satellites to derive their $\mathbf{J}$ and $\textit{E}$. To detect groups, we use the $\texttt{ENLINK}$ software, coupled with a statistical procedure that accounts for the observed phase-space uncertainties of these objects. We detect a total of $N=6$ groups, including the previously known mergers $\textit{Sagittarius}$, $\textit{Cetus}$, $\textit{Gaia-Sausage/Enceladus}$, $\textit{LMS-1/Wukong}$, $\textit{Arjuna/Sequoia/I'itoi}$ and one new merger that we call $\textit{Pontus}$. All of these mergers, together, comprise $62$ objects ($\approx 25\%$ of our sample). We discuss their members, orbital properties and metallicity distributions. We find that the three most metal-poor streams of our Galaxy -- "C-19" ([Fe/H]$=-3.4$ dex), "Sylgr" ([Fe/H]$=-2.9$ dex) and "Phoenix" ([Fe/H]$=-2.7$ dex) -- are associated with $\textit{LMS-1/Wukong}$; showing it to be the most metal-poor merger. The global dynamical atlas of Milky Way mergers that we present here provides a present-day reference for galaxy formation models.

description: The compelling original idea of a time crystal has referred to a structure that repeats in time as well as in space, an idea that has attracted significant interest recently. While obstructions to realize such structures became apparent early on, focus has shifted to seeing a symmetry breaking in time in periodically driven systems, a property of systems referred to as discrete time crystals. In this work, we introduce Stark time crystals based on a type of localization that is created in the absence of any spatial disorder. We argue that Stark time crystals constitute a phase of matter coming very close to the original idea and exhibit a symmetry breaking in space and time. Complementing a comprehensive discussion of the physics of the problem, we move on to elaborating on possible practical applications, and we argue that the physical demands of witnessing genuine signatures of many-body localization in large systems may be lessened in such physical systems.

Renaissance

description: The most painted scene from the Decameron's first tale of day five shows Cymon stands gazing at Iphigenia, while she is sleeping in the woods. After admiring her beauty, the young nobleman changes from a badly mannered lout to an ideal polymath. Falling instantly in love Cymon turn into wise, becoming a model of the transforming power of beauty. The pictorial tradition usually respects the Decameron's original text and represents Cymon resting on his staff while peering over Iphigenia, in a calm, meditative state of mind. In only a few cases, two of which depict in the Calumny of Botticelli, Cymon’s pose changes to a hand-to-face posture, typical of melancholy figures. In this paper we examine the close connection that joins melancholy and love from Antiquity to the Modern Age, attempted to argue that Cymon's hand-to-face posture is symptomatic of an astonishment, of a mental alienation caused by Love, which is similar to melancholy. Traditionally considered pathological conditions strictly relate to madness, Love insanity and Melancholy become during the Renaissance the only two mental dispositions that make man receptive to divine inspiration. It was Marsilio Ficino, the great Florentine philosopher and commentator on Plato's Dialogues, who gave such unprecedented importance to them, providing also relevance to vision of beauty, through which man's soul may approach heavenly beauty and be reminded of its divine origins.

description: We study a simplified system of the original Ericksen--Leslie equations for the flow of nematic liquid crystals. This is a coupled non-parabolic dissipative dynamic system. We show the convergence of global classical solutions to single steady states as time goes to infinity (uniqueness of asymptotic limit) by using the Łojasiewicz--Simon approach. Moreover, we provide an estimate on the convergence rate. Finally, we discuss some possible extensions of the results to certain generalized problems with changing density or free-slip boundary condition.

description: We present a comparative analysis of a set of GaAs-based THz quantum cascade lasers, based on longitudinal-optical phonon scattering depopulation, by using an ensemble Monte Carlo simulation, including both carrier-carrier and carrier-phonon scattering. The simulation shows that the parasitic injection into the states below the upper laser level limits the injection efficiency and thus the device performance at the lasing threshold. Additional detrimental effects playing an important role are identified. The simulation results are in reasonable agreement with the experimental findings.

description: This essay discusses two early encounters of theater that took place in different parts of the world at approximately the same time: in the German-speaking countries in Europe and on the islands of Japan in Asia during the second half of the sixteenth century and the first decades of the seventeenth century. In both cases a particular kind of “national” theater emerged from these developments, which was able to embrace elements of highly diverse origins: Johann Wolfgang von Goethe’s Weimar theater plays and devices from different European performance cultures, and Izumo no Okuni’s kabuki elements stemming from a range of genres, including the Christian mystery plays. These new forms, recognized as a national theater, came into existence by way of intercultural performances. Ultimately, what came into being out of an “intercultural” encounter was later deemed genuinely “intracultural.”

description: This article explores Rosanna Raymond’s performative intervention titled “Soli I Tai—Soli I Uta” (Tread on the Sea—Tread on the Land). Today, many cultural institutions try to develop progressive strategies to facilitate “intercultural dialogue.” In this endeavor, performative strategies are explored, some of which are developed in collaboration with experts from so-called “source communities.” Such collaborations have longer histories in Australia, Aotearoa New Zealand, or Canada. In central Europe, and especially in Germany, this has been a more recent development. One prominent example is the one-month artist residency of the Pacific artist Rosanna Raymond (b. 1967) at the Ethnological Museum Berlin in 2014, which culminated in her “acti.VA.tion” entitled “Soli I Tai—Soli I Uta.” My article analyzes how Raymond’s performative intervention dramaturgically put different epistemic systems and “ways of knowing” into a contrasting relationship and thus enabled spectators to gain declarative epistemic knowledge, that is to say, knowledge about knowledge and different “ways of knowing.”

Random Hypersurface Models for Extended Object Tracking
Creators: name: Baum, Marcus
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: Target tracking algorithms usually assume that the received measurements stem from a point source. However, in many scenarios this assumption is not feasible so that measurements may stem from different locations, named measurement sources, on the target surface. Then, it is necessary to incorporate the target extent into the estimation procedure in order to obtain robust and precise estimation results. This paper introduces the novel concept of Random Hypersurface Models for extended targets. A Random Hypersurface Model assumes that each measurement source is an element of a randomly generated hypersurface. The applicability of this approach is demonstrated by means of an elliptic target shape. In this case, a Random Hypersurface Model specifies the random (relative) Mahalanobis distance of a measurement source to the center of the target object. As a consequence, good estimation results can be obtained even if the true target shape significantly differs from the modeled shape. Additionally, Random Hypersurface Models are computationally tractable with standard nonlinear stochastic state estimators.

description: Aims Although heart failure (HF) with preserved ejection fraction (HFpEF) is a leading cause for hospitalization, its overall costs remain unclear. Therefore, we assessed the health care-related costs of ambulatory HFpEF patients and the effect of spironolactone. Methods and results The aldosterone receptor blockade in diastolic HF trial is a multicentre, prospective, randomized, double-blind, placebo-controlled trial conducted between March 2007 and April 2011 at 10 sites in Germany and Austria that included 422 ambulatory patients [mean age: 67 years (standard deviation: 8); 52% women]. All subjects suffered from chronic New York Heart Association (NYHA) class II or III HF and preserved left ventricular ejection fraction of 50% or greater. They also showed evidence of diastolic dysfunction. Patients were randomly assigned to receive 25 mg of spironolactone once daily (n = 213) or matching placebo (n = 209) with 12 months of follow-up. We used a single-patient approach to explore the resulting general cost structure and included medication, number of general practitioner and cardiologist visits, and hospitalization in both acute and rehabilitative care facilities. The average annual costs per patient in this cohort came up to euro1, 118 (± 2,475), and the median costs were euro332. We confirmed that the main cost factor was hospitalization and spironolactone did not affect the overall costs. We identified higher HF functional class (NYHA), male patients with low haemoglobin level, with high oxygen uptake (VO(2)max) and coronary artery disease, hyperlipidaemia, and atrial fibrillation as independent predictors for higher costs. Conclusions In this relatively young, oligosymptomatic, and with regard to the protocol without major comorbidities patient cohort, the overall costs are lower than expected compared with the HFrEF population. Further investigation is needed to investigate the impact of, for example, comorbidities and their effect over a longer period of time. Simultaneously, this analysis suggests that prevention of comorbidities are necessary to reduce costs in the health care system.

description: Purpose: To develop a customized method to produce uniform phantoms for task-based assessment of CT image quality. Methods: Contrasts between polymethyl methacrylate (PMMA) and fructose solutions of different concentrations (240, 250, 260, 280, 290, 300, 310, 320, 330, and 340 mg/mL) were calculated. A phantom was produced by laser cutting PMMA slabs to the shape of a patient's neck. An opening of 10 mm diameter was cut into the left parapharyngeal space. An angioplasty balloon was inserted and filled with the fructose solutions to simulate low-contrast lesions. The phantom was scanned with six tube currents. Images were reconstructed with filtered back projection (FBP) and adaptive iterative dose reduction 3D (AIDR 3D). Calculated and measured contrasts were compared. The phantom was evaluated in a detectability experiment using images with 4 and 20 HU lesion contrast. Results: Low-contrast lesions of 4, 9, 11, 13, 18, 20, 24, 30, 35, and 37 HU contrast were simulated. Calculated and measured contrasts correlated excellently (r = 0.998; 95% confidence interval: 0.991 to 1). The mean +/- SD difference was 0.41 +/- 2.32 HU (P < 0.0001). Detection accuracy and reader confidence were 62.9 +/- 18.2% and 1.58 +/- 0.68 for 4 HU lesion contrast and 99.6 +/- 1.3% and 4.27 +/- 0.92 for 20 HU lesion contrast (P < 0.0001), confirming that the method produced lesions at the threshold of detectability. Conclusion: A cost-effective and flexible approach was developed to create uniform phantoms with low-contrast signals. The method should facilitate access to customized phantoms for task-based image quality assessment.

description: We have probed a section (l ~ 150, b ~ -60) of the trailing tidal arm of the Sagittarius dwarf spheroidal galaxy by identifying a sample of Red Clump stream stars. Red Clump stars are not generally found in the halo field, but are found in significant numbers in both the Sagittarius galaxy and its tidal streams, making them excellent probes of stream characteristics. Our target sample was selected using photometric data from the Sloan Digital Sky Survey, Data Release 6, which was constrained in color to match the Sagittarius Red Clump stars. Spectroscopic observations of the target stars were conducted at Kitt Peak National Observatory using the WIYN telescope. The resulting spectroscopic sample is magnitude limited and contains both main sequence disk stars and evolved Red Clump stars. We have developed a method to systematically separate these two stellar classes using kinematic information and a Bayesian approach for surface gravity determination. The resulting Red Clump sample allows us to determine an absolute stellar density of ρ = 2.7 +/- 0.5 RC stars kpc-3 at this location in the stream. Future measurements of stellar densities for a variety of populations and at various locations along the streams will lead to a much improved understanding of the original nature of the Sagittarius galaxy and the physical processes controlling its disruption and subsequent stream generation.

description: Coupling a quantum many-body system to an external environment dramatically changes its dynamics and offers novel possibilities not found in closed systems. Of special interest are the properties of the steady state of such open quantum many-body systems, as well as the relaxation dynamics toward the steady state. However, new computational tools are required to simulate open quantum many-body systems, as methods developed for closed systems cannot be readily applied. Several approaches to simulating open many-body systems are reviewed, and advances made in recent years toward the simulation of large system sizes are pointed out.

description: Background: The current COVID-19 pandemic comes with multiple psychological stressors due to health-related, social, economic, and individual consequences and may cause psychological distress. The aim of this study was to screen the population in Germany for negative impact on mental health in the current COVID-19 pandemic and to analyze possible risk and protective factors. Methods: A total of 6,509 people took part in an online survey in Germany from 27 March to 6 April. The questionnaire included demographic information and ascertained psychological distress, anxiety and depressive symptoms, and risk and protective factors. Results: In our sample, over 50% expressed suffering from anxiety and psychological distress regarding the COVID-19 pandemic. Participants spent several hours per day thinking about COVID-19 (M = 4.45). Psychological and social determinants showed stronger associations with anxiety regarding COVID-19 than experiences with the disease. Conclusions: The current COVID-19 pandemic does cause psychological distress, anxiety, and depression for large proportions of the general population. Strategies such as maintaining a healthy lifestyle and social contacts, acceptance of anxiety and negative emotions, fostering self-efficacy, and information on where to get medical treatment if needed, seem of help, while substance abuse and suppression of anxiety and negative emotions seem to be associated with more psychological burden.
Thermo-plastic constitutive relations and a variational solution technique using finite elements
Creators: name: Charlwood, Robin Gurney
Publisher: name: University of British Columbia
Year: 2011

description: This study is concerned with a thermo-elasto-plastic continuum in which the thermodynamic coupling between material deformations, heat generation and flow are included. The elasto-plastic behavior is represented by a linear "rate-type" theory and restricted to infinitesimal deformations. The heat flow equations are posed in incremental form for the linear theory of heat conduction. The theory is such that the conservation laws of thermodynamics are satisfied. A displacement formulation is used and the field equations are shown to be linear operator equations. The operators are tested for symmetry and positive-definiteness in order to test their suitability for solution by a variational method. It is shown that the special case of thermo-elasticity may be solved by minimisation of a functional and that convergence of approximate solutions may be predicted. In the general case of thermo-elasto-plasticity, the operator is shown to be unsymmetric. Therefore an iterative functional is introduced in order to obtain a solution by a variational method. Approximate solutions to some illustrative problems are found using a finite-element-formulation, and it is shown that the results are consistent with expected physical behavior.

The proton microquasar

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a model for high-energy emission in microquasars where the energy content of the jets is dominated by relativistic protons. We also include a primary leptonic component. Particles are accelerated up to relativistic energies in a compact region located near the base of the jet, where most of the emission is produced. We calculate the production spectrum due to proton and electron synchrotron radiation and photohadronic interactions. The target field for proton-photon collisions is provided by the synchrotron radiation in the acceleration region. In models with a significant leptonic component, strong internal photon-photon absorption can attenuate the emission spectrum at high energies. Depending on the values of the parameters, our model predicts luminosities in the range 10^34-10^37 erg s^-1 up to GeV energies, with a high-energy tail that can extend up to 10^16 eV. In some cases, however, absorption effects can completely suppress the emission above 10 GeV, giving rise to different spectral shapes. These results can be tested in the near future by observations with instruments like GLAST-Fermi, HESS II and MAGIC II.

description: Tumor-associated macrophages (TAMs) promote tumor growth and metastasis by suppressing tumor immune surveillance. Herein, we provide evidence that the immunosuppressive phenotype of TAMs is controlled by long-chain fatty acid metabolism, specifically unsaturated fatty acids, here exemplified by oleate. Consequently, en-route enriched lipid droplets were identified as essential organelles, which represent effective targets for chemical inhibitors to block in vitro polarization of TAMs and tumor growth in vivo. In line, analysis of human tumors revealed that myeloid cells infiltrating colon cancer but not gastric cancer tissue indeed accumulate lipid droplets. Mechanistically, our data indicate that oleate-induced polarization of myeloid cells depends on the mammalian target of the rapamycin pathway. Thus, our findings reveal an alternative therapeutic strategy by targeting the pro-tumoral myeloid cells on a metabolic level.

In the velocity distribution for three magnitude-binned subsamples we however find a novel structure at $(U, V) = (7, -19)$ km s$^{-1}$ in fainter samples, potentially related to the Coma Berenices stream. We also see a double-peaked feature in $U$-$W$ at $U \approx -30$ km s$^{-1}$ and in $V$-$W$ at $V \approx -20$ km s$^{-1}$ for fainter samples. We determine the velocity distribution and velocity moments as a function of absolute magnitude for two samples based on the bifurcation identified in Gaia Data Release 2 in the colour-magnitude diagram. The brighter, redder sequence has a larger velocity dispersion than the fainter, bluer sequence across all magnitudes. It is hard to reconcile this kinematic difference with a bifurcation caused purely by atmospheric composition, while it fits neatly with a significant age difference between the two sequences. Our results provide novel insights into the kinematic properties of white dwarfs and demonstrate the power of analytical techniques that work for the large fraction of stars that do not have measured radial velocities in the current era of large-scale astrometric surveys.

description: We investigate the effects of pseudoscalar-photon mixing on electromagnetic radiation in the presence of correlated extragalactic magnetic fields. We model the Universe as a collection of magnetic domains and study the propagation of radiation through them. This leads to correlations between Stokes parameters over large scales and consistently explains the observed large-scale alignment of quasar polarizations at different redshifts within the framework of the big bang model.

description: Aims: Impaired autonomic nervous system regulation is frequently observed in patients with stroke. The aim of this prospective study was to evaluate the impact of cardiac autonomic tone on functional outcome after the early post-stroke rehabilitation. Methods and results: One hundred and three consecutive patients (67 +/- 11 years, body mass index (BMI) 27.1 +/- 5.4 kg/m(2), 64% men) with ischaemic (84% of patients) and haemorrhagic stroke were studied. Depressed heart rate variability (HRV), as a surrogate marker of increased sympathetic tone, was defined by the standard deviation of NN intervals < 100 ms and HRV triangular index <= 20 assessed from a 24 h Holter electrocardiogram at admission to rehabilitation (23 +/- 16 days after stroke). Twenty-two per cent of patients had depressed HRV at baseline and were comparable with patients with normal HRV with regard to their functional [Barthel Index (BI), modified Rankin Scale (mRS), and Rivermead Motor Assessment (RMA)] and biochemical status. After a 4-week follow-up, 70% of patients with depressed HRV showed a cumulative functional disability, defined by mRS >= 4, BI <= 70, and RMA <= 5, in contrast to patients with normal HRV (35%,P = 0.003). Patients with depressed HRV showed a worse functional status by BI (-16%,P < 0.001), RMA (-12%,P < 0.05), and mRS (+16%,P < 0.01), compared with patients with normal HRV. Cumulative functional disability was associated with depressed HRV (odds ratio 4.25, 95% confidence interval 1.56-11.54,P < 0.005) after adjustment for age, sex, and body mass index (odds ratio 4.6, 95% confidence interval 1.42-14.97,P < 0.05). Conclusions: The presence of autonomic cardiovascular dysregulation in patients with subacute stroke was associated with adverse functional outcome after the early post-stroke rehabilitation.

description: Motivated by recent cosmic ray experimental results there has been a proposition for a scenario where a secluded dark matter particle annihilates, primarily, into Standard Model leptons through a low mass mediator particle. We consider several varieties of this scenario depending on the type of mixing among gauge bosons and we study the implications in novel direct dark matter experiments for detecting low energy recoiling electrons. We find significant event rates and time modulation effects, especially in the case where the mediator is massless, that may be complementary to those from recoiling nuclei.

description: We demonstrate sympathetic cooling of a 43Ca+ trapped-ion "memory" qubit by a 40Ca+ "coolant" ion near the ground state of both axial motional modes, whilst maintaining coherence of the qubit. This is an essential ingredient in trapped-ion quantum computers. The isotope shifts are sufficient to suppress decoherence and phase shifts of the memory qubit due to the cooling light which illuminates both ions. We measure the qubit coherence during 10 cycles of sideband cooling, finding a coherence loss of 3.3% per cooling cycle. The natural limit of the method is O(0.01%) infidelity per cooling cycle.

Face-based Selection of Corners in 3D Substructuring

description: In most recent substructuring methods, a fundamental role is played by the coarse space. For some of these methods (e.g. BDDC and FETI-DP), its definition relies on a 'minimal' set of coarse nodes (sometimes called corners) which assures invertibility of local subdomain problems and also of the global coarse problem. This basic set is typically enhanced by enforcing continuity of functions at some generalized degrees of freedom, such as average values on edges or faces of subdomains. We revisit existing algorithms for selection of corners. The main contribution of this paper consists of proposing a new heuristic algorithm for this purpose. Considering faces as the basic building blocks of the interface, inherent parallelism, and better robustness with respect to disconnected subdomains are among features of the new technique. The advantages of the presented algorithm in comparison to some earlier approaches are demonstrated on three engineering problems of structural analysis solved by the BDDC method.

Thermodynamic Geometry of black hole in the deformed Horava-Lifshitz gravity

description: We investigate the thermodynamic geometry and phase transition of Kehagias-Sfetsos black hole in the deformed Horava-Lifshitz gravity with coupling constant $λ=1$. The phase transition in black hole thermodynamics is thought to be associated with the divergence of the capacities. And the structures of these divergent points are studied. We also find that the thermodynamic curvature produced by the Ruppeiner metric is positive definite for all $r_+ > r_-$ and is divergence at $η_2=0$ corresponded to the divergent points of $C_Φ$ and $C_T$. These results suggest that the microstructure of the black hole has an effective repulsive interaction, which is very similar to the ideal gas of fermions. These may shine some light on the microstructure of the black hole.

The Past and Future History of Regulus

description: We show how the recent discovery of a likely close white dwarf companion to the well known star Regulus, one of the brightest stars in the sky, leads to considerable insight into the prior evolutionary history of this star, including the cause of its current rapid rotation. We infer a relatively narrow range for the initial masses of the progenitor system: M_{10} = 2.3 +/- 0.2 M_sun and M_{20} = 1.7 +/- 0.2 M_sun, where M_{10} and M_{20} are the initial masses of the progenitors of the white dwarf and Regulus, respectively. In this scenario, the age of the Regulus system would exceed 1 Gyr. We also show that Regulus, with a current orbital period of 40 days, has an interesting future ahead of it. This includes (i) a common envelope phase, and, quite possibly, (ii) an sdB phase, followed by (iii) an AM CVn phase with orbital periods < 1 hr. Binary evolution calculations are presented in support of this scenario. We also discuss alternative possibilities, emphasizing the present uncertainties in binary evolution theory. Thus, this one particular star system illustrates many different aspects of binary stellar evolution.

description: An algorithm to systematically and efficiently generate free fermionic heterotic string models was recently introduced. This algorithm has been adopted by the Free Fermionic Model Construction (FFMC) program at Baylor University. As its first application, the algorithm is being applied to systematically generate the complete set of free fermionic heterotic string models with untwisted left-moving (worldsheet supersymmetric) sectors, up to continually advancing Layer and Order. Statistical analysis of this study will be reported in the near future. However, in a series of separate notes we will be reporting some of the more interesting models that appear along the way. In this, our first such note, we reveal a different string embedding of E8 than is standard. That is, rather than realize E8 via an SO(16) embedding, 248 = 120 + 128, we realize it via an SU(9) embedding, 248 = 80 + 84 + 84-bar. This is obtained in a Layer 1, Order 6 model for which modular invariance itself dictates a gravitino sector accompany the gauge sector.

Tristram (1884) reported the Asia Minor Ground Squirrel Spermophilus xanthoprymnus as “exceedingly abundant on the sandy and stony plains of the uplands of Moab and Gilead [Palestine]”; this species was omitted from his earlier paper (Tristram 1866). Although Kock (1998) suggested that such evidence most probably results from confusion with a diurnal Psammomys obesus, Hoffman et al. (2005) continue to report S. xanthoprymnus as present in Syria and Jordan. This ground squirrel does not occur south of the Syrian-Turkish border (cf. Kryštufek & Vohralík 2012) and we are not aware of any observations within Syria. The Museum of Vertebrate Zoology at Harvard University holds a voucher labelled Citellus mugosaricus (= Spermophilus pygmaeus) (VertNet 2023). Species identity is certainly erroneous since S. pygmaeus is native to steppes to the north of the line Caucasus—Caspian Sea—Aral Sea (see map in Kryštufek & Vohralík 2012).
