description: We present high-precision photometry and polarimetry for the protoplanetary disk around HD142527, with a focus on determining the light scattering parameters of the dust. We re-reduced polarimetric differential imaging data of HD142527 in the VBB (735 nm) and H-band (1625 nm) from the ZIMPOL and IRDIS subinstruments of SPHERE/VLT. With polarimetry and photometry based on reference star differential imaging, we were able to measure the linearly polarized intensity and the total intensity of the light scattered by the circumstellar disk with high precision. We used simple Monte Carlo simulations of multiple light scattering by the disk surface to derive constraints for three scattering parameters of the dust: the maximum polarization of $P_{\rm max}$, the asymmetry parameter $g$, and the single-scattering albedo $ω$. We measure a reflected total intensity of $51.4\pm1.5$ mJy and $206\pm12$ mJy and a polarized intensity of $11.3\pm0.3$ mJy and $55.1\pm3.3$ mJy in the VBB and H-band, respectively. We also find in the visual range a degree of polarization that varies between $28\%$ on the far side of the disk and $17\%$ on the near side. The disk shows a red color for the scattered light intensity and the polarized intensity, which are about twice as high in the near-infrared when compared to the visual. We determine with model calculations the scattering properties of the dust particles and find evidence for strong forward scattering ($g\approx 0.5-0.75$), relatively low single-scattering albedo ($ω\approx 0.2-0.5$), and high maximum polarization ($P_{\rm max} \approx 0.5-0.75$) at the surface on the far side of the disk for both observed wavelengths. The optical parameters indicate the presence of large aggregate dust particles, which are necessary to explain the high maximum polarization, the strong forward-scattering nature of the dust, and the observed red disk color.

The Labour Movement and the National Question: The Communist Party ofYugoslavia in Macedonia in the Inter-War Period
Creators: name: Willemsen, Heinz
Publisher: name: Moving the Social
Year: 2014

description: In economically less developed countries, communism and nationalism tend to appear as closely related concepts, even though they might belong to ideologically different spheres. In the case of Macedonia, scholarship has viewed the domestic communist organization as an instrument in the service of a nationalist movement. However, even the still limited source material available today would allow one to draw a more complex picture of the situation. Typically East European by social background and world view, the Macedonian communists shared the scepticism of orthodox Marxists as regards nation and nationalism and resisted Soviet attempts to exploit national discontent in the Balkans in the early post-World War I era. In the wake of a severe inter-generational conflict, a group of young Belgrade students gained control of the Communist Party of Yugoslavia in the late 1930s. The subsequent transformation of the party according to the Bolshevik model prepared the ground for a greater emphasis on the national question, especially since the Comintern had decreed in 1935 the transition to a policy of national front.

description: Human behavior is notoriously difficult to change, but a disruption of the magnitude of the COVID-19 pandemic has the potential to bring about long-term behavioral changes. During the pandemic, people have been forced to experience new ways of interacting, working, learning, shopping, traveling, and eating meals. A critical question going forward is how these experiences have actually changed preferences and habits in ways that might persist after the pandemic ends. Many observers have suggested theories about what the future will bring, but concrete evidence has been lacking. We present evidence on how much U.S. adults expect their own post-pandemic choices to differ from their pre-pandemic lifestyles in the areas of telecommuting, restaurant patronage, air travel, online shopping, transit use, car commuting, uptake of walking and biking, and home location. The analysis is based on a nationally-representative survey dataset collected between July and October 2020. Key findings include that the new normal will feature a doubling of telecommuting, reduced air travel, and improved quality of life for some.

Studies of the interactions between stromal cells and B lymphoid progenitors
Creators: name: Lemoine, François Michel
Publisher: name: University of British Columbia
Year: 2010

description: The overall goal of the work, described in this thesis was to investigate the molecular mechanisms that regulate normal pre-B cell proliferation and how these may be altered in transformed pre-B cells. Monoclonal antibodies and molecular biological techniques have allowed a number of stages of pre-B cell differentiation to be defined but little is known about mechanisms controlling their proliferation. Studies of pre-B cell production in animal models and in long-term cultures that support pre-B cell proliferation have suggested that stromal cells play a key role in this regard. As a first step to investigate the mechanisms involved, a number of pre-B cell supportive murine stromal cell lines were isolated and characterized. A number of pre-B cell lines were also isolated, cloned and characterized. From these, spontaneous and Abelson murine leukemia virus transformants were derived. These cell lines were then used in co-culture experiments to demonstrate that stromal cells constitutively secrete a pre-B stimulating factor. Characterization of the pre-B cell stimulating activity produced by one stromal cell line (M2-10B4) showed it to be a 10 Kd molecule sensitive to freezing and different from any cloned hemopoietic growth factor described to date. The possibility that extracellular matrix components might be involved in stromal cell-mediated control of pre-B cell growth was also investigated. It was found that pre-B cells attach specifically to fibronectin and that although fibronectin by itself cannot support pre-B cell proliferation, it contributes to stromal cell stimulation of pre-B cell growth. Both of these mechanisms were found to be affected in malignantly transformed pre-B cell populations irrespective of the mode of transformation. Transformed pre-B cells were found to have acquired the ability to secrete a novel 3 Kd autocrine factor that is also capable of stimulating normal pre-B cells. In addition transformed pre-B cells showed a greatly decreased ability to adhere to fibronectin and had become insensitive to the synergistic stimulating effect of fibronectin. It will be of interest to determine in the future whether these findings have a counterpart in human malignant pre-B cell populations.

Redshift of light emitted by particles orbiting a black hole immersed in a strong magnetic field

description: In this paper we analyze the frequency shifts of the light emitted by particles describing stable circular geodesics around a static black hole immersed in an external magnetic field of arbitrary strength. This system is represented by the Ernst solution of the Einstein-Maxwell equations. The presence of the magnetic field and its magnitude affects both the geodesics and the red-blueshifts of the light emitted by neutral or charged particles orbiting the black hole. When the magnetic field is turned off we recover the characteristic redshifts coming from particles orbiting a Schwarzschild black hole.
Causal Limit of Neutron Star Maximum Mass in $f(R)$ Gravity in View of GW190814

description: We investigate the causal limit of maximum mass for stars in the framework of$f(R)$ gravity. We choose a causal equation of state, with variable speed of sound, and with the transition density and pressure corresponding to the SLy equation of state. The transition density is chosen to be equal to twice the saturation density $ρ_t\sim 2ρ_0$, and also the analysis is performed for the transition density, chosen to be equal to the saturation density $ρ_t\sim ρ_0$. We examine numerically the combined effect of the stiff causal equation of state and of the sound speed on the maximum mass of static neutron stars, in the context of Jordan frame of $f(R)$ gravity. This yields the most extreme upper bound for neutron star masses in the context of extended gravity. As we will evince for the case of $R^2$ model, the upper causal mass limit lies within, but not deeply in, the mass-gap region, and is marginally the same with the general relativistic causal maximum mass, indicating that the $\sim 3M_{\odot}$ general relativistic limit is respected. In view of the modified gravity perspective for the secondary component of the GW190814 event, we also discuss the strange star possibility. Using several well established facts for neutron star physics and the Occam's razor approach, although the strange star is exciting, for the moment, it remains a possibility for describing the secondary component of GW190814. We underpin the fact that the secondary component of the compact binary GW190814 is probably a neutron star, a black hole or even a rapidly rotating neutron star, but not a strange star. We also discuss, in general, the potential role of the extended gravity description for the binary merging.

Approximately Einstein ACH metrics, volume renormalization, and an invariant for contact manifolds
Creators: name: Seshadri, Neil
Publisher: name: arXiv
Year: 2007
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: To any smooth compact manifold $M$ endowed with a contact structure $H$ and partially integrable almost CR structure $J$, we prove the existence and uniqueness, modulo high-order error terms and diffeomorphism action, of an approximately Einstein ACH (asymptotically complex hyperbolic) metric $g$ on $M\times (-1,0)$. We consider the asymptotic expansion, in powers of a special defining function, of the volume of $M\times (-1,0)$ with respect to $g$ and prove that the log term coefficient is independent of $J$ (and any choice of contact form $θ$), i.e., is an invariant of the contact structure $H$. The approximately Einstein ACH metric $g$ is a generalisation of, and exhibits similar asymptotic boundary behaviour to, Fefferman's approximately Einstein complete Kähler metric $g_+$ on strictly pseudoconvex domains. The present work demonstrates that the CR-invariant log term coefficient in the asymptotic volume expansion of $g_+$ is in fact a contact invariant. We discuss some implications this may have for CR $Q$-curvature. The formal power series method of finding $g$ is obstructed at finite order. We show that part of this obstruction is given as a one-form on $H^*$. This is a new result peculiar to the partially integrable setting.

description: The discriminant-analysis method has been applied to optimize the exotic-beam charge recognition in a projectile fragmentation experiment. The experiment was carried out at the GSI using the fragment separator (FRS) to produce and select the relativistic secondary beams, and the ALADIN setup to measure their fragmentation products following collisions with Sn target nuclei. The beams of neutron poor isotopes around 124La and 107Sn were selected to study the isospin dependence of the limiting temperature of heavy nuclei by comparing with results for stable 124Sn projectiles. A dedicated detector to measure the projectile charge upstream of the reaction target was not used, and alternative methods had to be developed. The presented method, based on the multivariate discriminant analysis, allowed to increase the efficacy of charge recognition up to about 90%, which was about 20% more than achieved with the simple scalar methods.

description: Depression is a public health issue which severely affects one's well being and cause negative social and economic effect for society. To rise awareness of these problems, this publication aims to determine if long lasting effects of depression can be determined from electoencephalographic (EEG) signals. The article contains accuracy comparison for SVM, LDA, NB, kNN and D3 binary classifiers which were trained using linear (relative band powers, APV, SASI) and non-linear (HFD, LZC, DFA) EEG features. The age and gender matched dataset consisted of 10 healthy subjects and 10 subjects with depression diagnosis at some point in their lifetime. Several of the proposed feature selection and classifier combinations reached accuracy of 90% where all models where evaluated using 10-fold cross validation and averaged over 100 repetitions with random sample permutations.

description: During the 1970s, in the course of a renewal of European integration, German trade unions increasingly started to turn their attention towards the European level. In particular, the Confederation of German Trade Unions (DGB) shifted the attention to European policy preparation and making. This realignment also sheds light on the need of a more coherent internal coordination in regard of European policies. For this purpose a new department (Abteilung Europäische Integration) was established inside the structure of the DGB. Though the department had been set-up with high expectations, it remained a temporary institution, since it had been closed only after three years. This paper scrutinises the background and motivations for both the beginnings and the closure of the DGB’s European Integration department, concentrating in detail on organisational aspects that still constitute a desideratum within research on Europeanisation.

description: During the research cruise AL547 with RV ALKOR (October 20-31, 2020), a collaborative underwater network of ocean observation systems was deployed in Boknis Eck (SW Baltic Sea, German exclusive economic zone (EEZ)) in the context of the project ARCHES (Autonomous Robotic Networks to Help Modern Societies). This network was realized via a Digital Twin Prototype approach. During that period different scenarios were executed to demonstrate the feasibility of Digital Twins in an extreme environment such as underwater. One of the scenarios showed the collaboration of stage IV Digital Twins with their physical counterparts on the seafloor. This way, we address the research question, whether Digital Twins represent a feasible approach to operate mobile ad hoc networks for ocean and coastal observation.

description: This article focuses on the state of research relating to trade unions and European politics. An overview on the development of the European Trade Union Congress (ETUC) is followed by a glance at the trade unions’ programmatic positions regarding ideas and concepts of European integration. In reference to the dictum of Vobrubas, revealing the lack of a genuine intellectual discussion about Europe, it is possible to trace an intellectual critique concerning Europe from the right wing of the political spectrum as well as from the left. From the trade unions’ point of view the debate on the future of Europe focussed on the establishment of a balance between economic and social aspects of integration. Since academic literature dealing with trade unionism is as comprehensive as literature on European integration it could be assumed that the combination of both entails similar results. However, a short view on trade union literature regarding European integration as well as a glance at European literature concerning trade unionism shows the limits of current academic research.

description: About 25% of the Milky Way globular clusters (GCs) exhibit unusually extended color distribution of stars in the horizontal-branch (HB) phase. This phenomenon is now best understood as due to the presence of helium enhanced second generation subpopulations, which has raised a possibility that these peculiar GCs might have a unique origin. Here we show that these GCs with extended HB are clearly distinct from other normal GCs in kinematics and mass. The GCs with extended HB are more massive than normal GCs, and are dominated by random motion with no correlation between kinematics and metallicity. Surprisingly, however, when they are excluded, most normal GCs in the inner halo show clear signs of dissipational collapse that apparently led to the formation of the disk. Normal GCs in the outer halo share their kinematic properties with the extended HB GCs, which is consistent with the accretion origin. Our result further suggests heterogeneous origins of GCs, and we anticipate this to be a starting point for more detailed investigations of Milky Way formation, including early mergers, collapse, and later accretion.

description: The excitonic recombinations in hexagonal boron nitride (hBN) are investigated with spatially resolved cathodoluminescence spectroscopy in the UV range. Cathodoluminescence images of an individual hBN crystallite reveals that the 215 nm free excitonic line is quite homogeneously emitted along the crystallite whereas the 220 nm and 227 nm excitonic emissions are located in specific regions of the crystallite. Transmission electron microscopy images show that these regions contain a high density of crystalline defects. This suggests that both the 220 nm and 227 nm emissions are produced by the recombination of excitons bound to structural defects.

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: This work contains the teleparallel version of the stationary axisymmetric solutions. We obtain the tetrad and the torsion fields representing these solutions. The tensor, vector and axial-vector parts of the torsion tensor are evaluated. It is found that the axial-vector has component only along $ρ$ and $z$ directions. The three possibilities of the axial vector depending on the metric function $B$ are discussed. The vector related with spin has also been evaluated and the corresponding extra Hamiltonian is furnished. Further, we use the teleparallel version of M$\ddot{o}$ller prescription to find the energy-momentum distribution of the solutions. It is interesting to note that (for $λ=1$) energy and momentum densities in teleparallel theory are equal to the corresponding quantities in GR plus an additional quantity in each, which may become equal under certain conditions. Finally, we discuss the two special cases of the stationary axisymmetric solutions.

description: The possible existence of axion-like particles could lead to a new type of long distance communication. In this work, basic antenna concepts are defined and a Friis-like equation is derived to facilitate long-distance link calculations. An example calculation is presented showing that communication over distances of 1000 km or more may be possible for $m_{a}< 3.5$ meV and $g_{aγγ} > 5 \times 10^{- 8} {\text{GeV}}^{- 1}$.
description: 18 pages, including 3 figures Version 2 has been modified to show portions of the coupling-mass plane that may lead to long distance communication, rather than concentrating on an example using the PVLAS parameters

description: This volume covers Leg 50 of the cruises of the Drilling Vessel Glomar Challenger. Our knowledge of the earliest stages in the evolution of the Atlantic Ocean remains very limited. Although much progress has been made by studying the geological record of sedimentary basins from various Atlantic margins and by drilling in the deep ocean, the oldest part of the record is still unknown. Recent Glomar Challenger cruises in the Central and North Atlantic, including DSDP Leg 50, have added substantial information bearing on our still-schematic views on the evolution of rifted margins. Although drilling into the deep oceanic basins at sites as close as possible to the foot of a margin is a direct and powerful method to study the early history of margins, this approach is difficult because the most interesting targets are generally beneath the thick sediments of continental rises. In the search for target areas where the Glomar Challenger drill could reach very old strata, the eastern Atlantic margins have long been considered particularly attractive, because unlike their western counterparts that are buried by a thick wedge of Tertiary hemipelagic rise sediments they are characterized by poorly developed continental rises. The margin off Morocco is one of these "starved" margins and has many features that make it especially suitable for study by deep drilling. Since it is among the oldest "starved" passive margins of the Atlantic — and hence of the world — we can here address both the Jurassic history of the ocean and the fundamental questions of the evolution of passive margins. Drilling into the Moroccan Basin on Leg 50 aimed at filling a specific gap in our understanding of the pre-Oxfordian history of both the Atlantic and the world ocean. The Glomar Challenger left Funchal, on the island of Madeira on 11 September 1976 and returned to Funchal, Madeira Islands in November, 1976.

description: We consider the diffusion of a non-relativistic heavy quark of fixed mass M, in a one-dimensionally expanding and strongly coupled plasma using the AdS/CFT duality. The Green's function constructed around a static string embedded in a background with a moving horizon, is identified with the noise correlation function in a Langevin approach. The (electric) noise decorrelation is of order 1/T(τ) while the velocity de-correlation is of order MD(τ)/T(τ). For MD>1, the diffusion regime is segregated and the energy loss is Langevin-like. The time dependent diffusion constant D(τ) asymptotes its adiabatic limit 2/π\sqrtλ T(τ) when τ/τ_0=(1/3η_0τ_0)^3 where η_0 is the drag coefficient at the initial proper time τ_0.

description: Due to the common neurodevelopmental origin and easy accessibility, the retina serves as a surrogate marker for changes in the brain. Hence, Optical Coherence Tomography (OCT), a tool to examine the neuronal layers of retina has gained importance in investigating psychiatric disorders. Several studies in the last decade have reported retinal structural alterations in schizophrenia (SCZ), bipolar disorder (BD), and major depressive disorder (MDD). However, the findings are inconsistent. Hence, we conducted a meta-analysis to investigate alterations in OCT parameters in patients with SCZ, BD and MDD. We searched electronic databases for studies that examined OCT parameters in patients with SCZ, BD and MDD published up to January 2023. The primary outcome measures were thickness and volumes of the retinal Nerve Fibre Layer (RNFL). We conducted meta-analysis using a random effects model. The searches yielded 2638 publications of which 43 studies were included in the final analysis across all disorders. Compared to controls, the RNFL was thinner in SCZ patients (SMD = −0.37, p = <0.001) and BD patients (SMD = −0.67, p = < 0.001), but not in MDD patients (SMD = −0.08, p = 0.54). On quadrant wise analysis, temporal quadrant RNFL was thinner in SCZ but not in BD, while all other quadrants were thinner in both SCZ and BD. We found significant reductions in RNFL thickness in SCZ and BD, but not in MDD. The differential involvement in various quadrants and parameters across the disorders has potential implications for using retinal parameters as a diagnostic biomarker.

Weighted percolation on directed networks

description: We present an analysis of the percolation transition for general node removal strategies valid for locally tree-like directed networks. On the basis of heuristic arguments we predict that, if the probability of removing node $i$ is $p_i$, the network disintegrates if $p_i$ is such that the largest eigenvalue of the matrix with entries $A_{ij}(1-p_i)$ is less than 1, where $A$ is the adjacency matrix of the network. The knowledge or applicability of a Markov network model is not required by our theory, thus making it applicable to situations not covered by previous works. We test our predicted percolation criterion against numerical results for different networks and node removal strategies.

description: The recently adopted Ariel ESA mission will measure the atmospheric composition of a large number of exoplanets. This information will then be used to better constrain planetary bulk compositions. While the connection between the composition of a planetary atmosphere and the bulk interior is still being investigated, the combination of the atmospheric composition with the measured mass and radius of exoplanets will push the field of exoplanet characterisation to the next level, and provide new insights of the nature of planets in our galaxy. In this white paper, we outline the ongoing activities of the interior working group of the {\it Ariel} mission, and list the desirable theoretical developments as well as the challenges in linking planetary atmospheres, bulk composition and interior structure.

Covariant Mappings for the Description of Measurement, Dissipation and Decoherence in Quantum Mechanics

Publisher: name: arXiv
Year: 2007
Subjects: subject: Quantum Physics (quant-ph)

description: The general formalism of quantum mechanics for the description of statistical experiments is briefly reviewed, introducing in particular position and momentum observables as POVM characterized by their covariance properties with respect to the isochronous Galilei group. Mappings describing state transformations both as a consequence of measurement and of dynamical evolution for a closed or open system are considered with respect to the general constraints they have to obey and their covariance properties with respect to symmetry groups. In particular different master equations are analyzed in view of the related symmetry group, recalling the general structure of mappings covariant under the same group. This is done for damped harmonic oscillator, two-level system and quantum Brownian motion. Special attention is devoted to the general structure of translation-covariant master equations. Within this framework a recently obtained quantum counterpart of the classical linear Boltzmann equation is considered, as well as a general theoretical framework for the description of different decoherence experiments, pointing to a connection between different possible behaviours in the description of decoherence and the characteristic functions of classical Lévy processes.
