description: We discovered Fe $K_α$ complex emission and pulsation in two highly variable sources (4XMM J174917.7--283329, 4XMM J174954.6--294336). The equivalent widths of 6.4 and 6.7 keV lines of 4XMM J174917.7--283329 are $99^{+84}_{-72}$ and $220^{+160}_{-140}$ eV, respectively. The continuum is fitted by a partially absorbed apec model with plasma temperature of $kT=13^{+10}_{-2}$ keV. The inferred mass of the white dwarf (WD) is $0.9^{+0.3}_{-0.2}\ M_{\odot}$. We detected pulsations with a period of $1212\pm3$ s and a pulsed fraction of $26\pm6\%$. The light curves of 4XMM J174954.6--294336 display asymmetric eclipse and dipping behaviour. To date, this is only the second intermediate polar (IP) that shows a total eclipse in X-rays. The spectrum of the sources is characterized by a power-law model with photon index $Γ=0.4\pm0.2$. The equivalent widths of the 6.4 keV and 6.7 keV iron lines are $171^{+99}_{-79}$ and $136^{+89}_{-81}$ eV, respectively. The continuum is described by emission from optically thin plasma with a temperature of $kT\sim35$ keV. The inferred mass of the WD is $1.1^{+0.2}_{-0.3}\ M_{\odot}$. We discovered coherent pulsations from the source with a period of $1002\pm2$ s. The pulsed fraction is $66\pm15\%$. The measured spin period, hard photon index, and equivalent width of the fluorescent Fe $K_α$ line in both sources are consistent with the values found in IP. While 4XMM J174954.6--294336 was already previously classified as an IP, we also suggest 4XMM J174917.7--283329 as a new IP. The X-ray eclipses in 4XMM J174954.6--294336 are most likely caused by a low-mass companion star obscuring the central X-ray source. The asymmetry in the eclipse is likely caused by a thick bulge that intercepts the line of sight during the ingress phase but not during the egress phase located behind the WD along the line of sight.

description: The intrinsic carrier transport dynamics in phosphorene is theoretically examined. Utilizing a density functional theory treatment, the low-field mobility and the saturation velocity are characterized for both electrons and holes in the monolayer and bilayer structures. The analysis clearly elucidates the crystal orientation dependence manifested through the anisotropic band structure and the carrier-phonon scattering rates. In the monolayer, the hole mobility in the armchair direction is estimated to be approximately five times larger than in the zigzag direction at room temperature (460 cm$^2$/Vs vs. 90 cm$^2$/Vs). The bilayer transport, on the other hand, exhibits a more modest anisotropy with substantially higher mobilities (1610 cm$^2$/Vs and 760 cm$^2$/Vs, respectively). The calculations on the conduction-band electrons indicate a comparable dependence while the characteristic values are generally smaller by about a factor of two. The variation in the saturation velocity is found to be less pronounced. With the anticipated superior performance and the diminished anisotropy, few-layer phosphorene offers a promising opportunity particularly in p-type applications.
Queer Korean diaspora: an ethnography of geopolitics
Creators: name: Eda, Haruki
Publisher: name: No Publisher Supplied
Year: 2022

description: Limited empirical research exists on social movements among overseas Koreans, whose divergent experiences of migration and identity complicate the dynamics of ethnic solidarity. Besides the prolonged Cold War ideological division, Korean communities in Japan and the United States face alienation rooted in racial subordination and heteropatriarchal norms. In major U.S. cities, diverse Korean subjects gravitate towards grassroots organizing, including transnational adoptees, Zainichi Koreans (Koreans in/from Japan), and queer-identified individuals. Existing sociological theory does not adequately explain the agency of such community organizers who negotiate differences and inequalities while seeking ethnic solidarity. I use the concept of queer diaspora to examine how geopolitical structures and discourses shape the embodied dimension of Korean ethnic community formation. I conduct ethnography of transnational Korean community organizing based on personal involvement since 2008 and five years of observation from 2015 until 2020 in New York and San Francisco, including 25 in-depth interviews and archival research with five U.S.-based organizations. My analysis shows how the organizers cultivate queer diasporic kinship by centering their alternative sense of place, time, and belonging. Their embodied practices animate ethnic community solidarity through what I call geopolitical healing, a process of articulating the sacredness of life and land. As a counter-hegemonic mode of ethnic mobilization, the queer Korean diaspora challenges liberal interpretations of sovereignty and nationhood that underscore the dominant discourse of Korean unification. Engaging with the literature on nationalism, social movements, and queer migration, my research draws attention to the spiritual realm of social life that manifest in a cultural ecology of spaces, bodies, and meanings.

description: Deep Learning (DL) algorithms provide numerous benefits in different applications, and they usually yield successful results in scenarios with enough labeled training data and similar class proportions. However, the labeling procedure is a cost and time-consuming task. Furthermore, numerous real-world classification problems present a high level of class imbalance, as the number of samples from the classes of interest differ significantly. In various cases, such conditions tend to promote the creation of biased systems, which negatively impact their performance. Designing unbiased systems has been an active research topic, and recently some DL-based techniques have demonstrated encouraging results in that regard. In this work, we introduce an extension of the Debiasing Variational Autoencoder (DB-VAE) for semantic segmentation. The approach is based on an end-to-end DL scheme and employs the learned latent variables to adjust the individual sampling probabilities of data points during the training process. For that purpose, we adapted the original DB-VAE architecture for dense labeling in the context of deforestation mapping. Experiments were carried out on a region of the Brazilian Amazon, using Sentinel-2 data and the deforestation map from the PRODES project. The reported results show that the proposed DB-VAE approach is able to learn and identify under-represented samples, and select them more frequently in the training batches, consequently delivering superior classification metrics.

description: The curvature-corrected field emission current density, obtained by linearizing at or below the Fermi energy, is investigated. Two special cases, corresponding to the peak of the normal energy distribution and the mean normal energy, are considered. It is found that the current density evaluated using the mean normal energy results in errors in the net emission current below 3% for apex radius of curvature, $R_a \geq 5$nm and for apex fields $E_a$ in the range $3-10$ V/nm for an emitter having work-function $ϕ= 4.5$eV. An analytical expression for the net field emission current is also obtained for locally parabolic tips using the generalized cosine law. The errors are found to be below 6% for $R_a \geq 5$nm over an identical range of apex field strengths. The benchmark current is obtained by numerically integrating the current density over the emitter surface and the current density itself computed by integrating over the energy states using the exact Gamow factor and the Kemble form for the WKB transmission coefficient. The analytical expression results in a remarkable speed-up in the computation of the net emission current and is especially useful for large area field emitters having tens of thousands of emission sites.

description: We explore the discovery potential of Higgs pair production at a 100 TeV collider via full leptonic mode. The same mode can be explored at the LHC when Higgs pair production is enhanced by new physics. We examine two types of fully leptonic final states and propose a partial reconstruction method. The reconstruction method can reconstruct some kinematic observables. It is found that the $m_{T2}$ variable determined by this reconstruction method and the reconstructed visible Higgs mass are important and crucial to discriminate the signal and background events. It is also noticed that a new variable, denoted as $Δm$ which is defined as the mass difference of two possible combinations, is very useful as a discriminant. We also investigate the interplay between the direct measurements of $t\bar{t} h$ couplings and other related couplings and trilinear Higgs coupling at hadron colliders and electron-positron colliders.

description: In recent years the number of diamond wires on the market increased with the importance of the
diamond wire process for silicon wafer production. These wires differ in many parameters and no optimum is known
yet. For a wafering company the detailed wire parameters are less important as long as the wire produces high quality
wafers with low wire consumption. This work therefore presents an evaluation of ten diamond wires that focuses on
wafer quality in terms of wafer total thickness variation. It is shown that this evaluation should be valid for various wire
saws, several changes of the sawing parameters and both mono- and multicrystalline silicon. Furthermore the potential
wire consumption for the production of multicrystalline silicon wafers with a Meyer Burger DS 271 wire saw and
PEG 200 as coolant is estimated to be below 2 m/wafer.

description: We obtain a complete and exact in the weak-coupling limit ($U \rightarrow 0$) ground state phase diagram of the repulsive fermionic Hubbard model on the square lattice for filling factors $0 < n < 2$ and next-nearest-neighbour hopping amplitudes $0 \le t^{\prime} \le 0.5$. Phases are distinguished by the symmetry and the number of nodes of the superfluid order parameter. The phase diagram is richer than may be expected and typically features states with a high --- higher than that of the fundamental mode of the corresponding irreducible representation --- number of nodes. The effective coupling strength in the Cooper channel $λ$, which determines the critical temperature $T_c$ of the superfluid transition, is calculated in the whole parameter space and regions with high values of $λ$ are identified. It is shown that besides the expected increase of $λ$ near the Van Hove singularity line, joining the ferromagnetic and antiferromagnetic points, another region with high values of $λ$ can be found at quarter filling and $t^{\prime}=0.5$ due to the presence of a line of nesting at $t^{\prime} \ge 0.5$. The results can serve as benchmarks for controlled non-perturbative methods and guide the ongoing search for high-$T_c$ superconductivity in the Hubbard model.

description: We present a detailed analysis of broadband X-ray observations of the pulsar PSR J1420-6048 and its wind nebula (PWN) in the Kookaburra region with Chandra, XMM-Newton, and NuSTAR. Using the archival XMM-Newton and new NuSTAR data, we detected 68 ms pulsations of the pulsar and characterized its X-ray pulse profile which exhibits a sharp spike and a broad bump separated by ~0.5 in phase. A high-resolution Chandra image revealed a complex morphology of the PWN: a torus-jet structure, a few knots around the torus, one long (~7') and two short tails extending in the northwest direction, and a bright diffuse emission region to the south. Spatially integrated Chandra and NuSTAR spectra of the PWN out to 2.5' are well described by a power law model with a photon index $Γ {\approx}$ 2. A spatially resolved spectroscopic study, as well as NuSTAR radial profiles of the 3--7 keV and 7--20 keV brightness, showed a hint of spectral softening with increasing distance from the pulsar. A multi-wavelength spectral energy distribution (SED) of the source was then obtained by supplementing our X-ray measurements with published radio, Fermi-LAT, and H.E.S.S. data. The SED and radial variations of the X-ray spectrum were fit with a leptonic multi-zone emission model. Our detailed study of the PWN may be suggestive of (1) particle transport dominated by advection, (2) a low magnetic-field strength (B ~ 5$μ$G), and (3) electron acceleration to ~PeV energies.

description: Methods. We use the code MCFOST to solve the non-LTE problem of line formation in non-axisymmetric accreting magnetospheres. We compute the Brγ line profile originating from accretion columns for models with different magnetic obliquities. We also derive monochromatic synthetic images of the Brγ line emitting region across the line profile. This spectral line is a prime diagnostics of magnetospheric accretion in young stars and is accessible with the long baseline near-infrared interferometer GRAVITY installed at the ESO Very Large Telescope Interferometer. Results. We derive Brγ line profiles as a function of rotational phase and compute interferometric observables, visibilities and phases, from synthetic images. The line profile shape is modulated along the rotational cycle, exhibiting inverse P Cygni profiles at the time the accretion shock faces the observer. The size of the line's emission region decreases as the magnetic obliquity increases, which is reflected in a lower line flux. We apply interferometric models to the synthetic visibilities in order to derive the size of the line-emitting region. We find the derived interferometric size to be more compact than the actual size of the magnetosphere, ranging from 50 to 90\% of the truncation radius. Additionally, we show that the rotation of the non-axisymmetric magnetosphere is recovered from the rotational modulation of the Brγ-to-continuum photo-centre shifts, as measured by the differential phase of interferometric visibilities.

process is based on a high temperature step in an atmosphere containing POCl3 and a BSG/SiOx layer stack

that the reaction of POCl3 with the SiOx layer results in the formation of a PSG layer converting a fraction of the SiOx

description: The large electric dipole moments associated with highly excited Rydberg states of atoms and molecules make gas-phase samples in these states very well suited to deceleration and trapping using inhomogeneous electric fields. The methods of Rydberg-Stark deceleration with which this can be achieved are reviewed here. Using these techniques, the longitudinal motion of beams of atoms and molecules moving at speeds as high as 2500~m/s have been manipulated, with changes in kinetic energy of up to $|ΔE_{\mathrm{kin}}|=1.3\times10^{-20}$~J ($|ΔE_{\mathrm{kin}}|/e=80$~meV or $|ΔE_{\mathrm{kin}}|/hc=650$~cm$^{-1}$) achieved, while decelerated and trapped samples with number densities of $10^6$--$10^7$~cm$^{-3}$ and translational temperatures of $\sim150$~mK have been prepared. Applications of these samples in areas of research at the interface between physics and physical chemistry are discussed.

description: The article explores the ways in which illustrated magazines of the Weimar period contribute to a larger gendering of transnational exchange, particularly through imagetext doubling and shifts. It takes the Weimar society magazine Uhu as a major reference point, investigating how it modelled itself on American lifestyle and 'smart' magazines and made use of the iconic figure of the 'Girl' to carve out a spatio-temporal continuum between 'Amerika' and Europe. While the Girl is a figure of the stage and screen as much as of the modern magazine, it is in the magazine that this figure comes into her own. The Girl incorporates modernity as a multimodal and multifaceted configuration much like the modern magazine itself. The article argues that the Girl enters the illustrated magazines not only as a subject matter but also as a tool of gendered self-reflection, particularly in the work of female writers, illustrators, and photographers.

description: We show that an interplay of double exchange and impurity randomness can explain the competition between metal-ferromagnetic and insulating charge ordered states in doped manganites. The double exchange is simplified in the Ising type, whereas the randomness is modeled by the Falicov-Kimball binary distribution. The combined model is considered in a framework of dynamical mean-field theory. Using the Kubo-Greenwood formalism, the transport coefficients are explicitly expressed in terms of single particle spectral functions. Dividing the system into two sublattices we have pointed out a direct calculation to the checkerboard charge order parameter and the magnetizations. Numerical results show us that the checkerboard charge order can settle inside the ferromagnetic state at low temperature. An insulator-metal transition is also found at the point of the checkerboard charge order-ferromagnetic transition.

description: We carry out a comprehensive survey of electromagnetic form factors of all light, heavy and heavy-light ground-state pseudoscalar and scalar mesons. Our analysis is based upon a Schwinger-Dyson equations treatment of a vector $\times$ vector contact interaction. It incorporates confinement and ensures axial vector and vector Ward-Takahashi identities are satisfied along with the corresponding corollaries such as the Goldberger-Treiman relations. The algebraic simplicity of the model allows us to compute the form factors at arbitrarily large virtualities of the probing photon momentum squared with relative ease. Wherever possible and insightful, we compare our results for the electromagnetic form factors and the charge radii with those obtained earlier through Schwinger-Dyson equations, lattice and with experimental observations available. We also comment on the scope and shortcomings of the model.

description: Protoporphyrin IX (PPIX) is formed from δ-aminolevulinic acid (ALA) during heme biosynthesis. Due to its cyclic tetrapyrrole core structure, it absorbs in the visible region of the electromagnetic spectrum and is thus colored. Both ALA and PPIX have become of great interest to neurosurgery, because in high-grade glioma, ALA diffuses into the tumor and is converted to PPIX. Fluorescence-guided resection (FGR) takes advantage of both the enrichment of PPIX in the tumor and its fluorescent properties, which enable visualization of tumor tissue. ALA-mediated FGR thus maximizes the extent of resection with better prognosis for patients. Tumor cells are able to produce porphyrins naturally or after administration of ALA, which is also reflected in elevated plasma fluorescence of cancer patients. PPIX might thus serve as a biomarker for monitoring of the tumor burden. A liquid chromatography-mass spectrometry (LC-MS)-based method is presented to quantify PPIX in blood and serum in the context of current fluorescence-based diagnostics. The method is able to distinguish between zinc PPIX, a component of red blood cells of importance in the detection of lead poisoning and iron deficiency anemia, and metal-free PPIX. In a proof-of-principle study, it was used to follow a time course of a glioblastoma patient undergoing surgery and confirmed elevated PPIX blood levels before ALA administration. During surgery, these blood levels increased about four-fold. The here developed 10 min reversed-phase LC-target MS method now allows patient screening with high specificity and throughput.

description: In order to improve the sawn-surface morphology of the wafers, ultrasonic vibration-assisted diamond
wire sawing is studied in this paper. Experiments are conducted with and without applying vibrations in order to
compare the effect of ultrasonic vibrations on surface characteristics of the sawn silicon. The surfaces without
vibration super-imposed show the characteristics of typical sawn surfaces produced by diamond wire sawing
consisting of crushed fragments and lines parallel with the wire direction. While the surfaces of grooves produced
ultrasonic vibration-assist displays intermittent patterns due to the recurring cutting action by diamond grits as a
result of ultrasonic vibrations. The grooves produced by ultrasonic vibration-assisted wire sawing have higher hybrid
parameters of the surface roughness (Sda and Sdq) compared to those without ultrasonic vibration-assisted attributed to
the formation of intermittent patterns. The higher Sdq value is reported as favorable in the literature for better light
absorption. The phase analysis shows no significant difference between the surfaces for all sawn grooves regardless
of the application of vibrations. The spectra mainly consist of Si-IV, a-Si and Si-III and Si-XII. In summary, it is
evident that the ultrasonic vibration-assisted diamond wire sawing process can improve the surface morphology of
the sawn wafers.

description: We present the discovery of a new satellite of asteroid (130) Elektra - S/2014 (130) 1 - in differential imaging and in integral field spectroscopy data over multiple epochs obtained with SPHERE/VLT. This new (second) moonlet of Elektra is about 2 km across, on an eccentric orbit and about 500 km away from the primary. For a comparative study, we also observed another triple asteroid system (93) Minerva. For both systems, component-resolved reflectance spectra of the satellites and primary were obtained simultaneously. No significant spectral difference was observed between the satellites and the primary for either triple system. We find that the moonlets in both systems are more likely to have been created by sub-disruptive impacts as opposed to having been captured.

description: Today’s costs of silicon wafer material of a photovoltaic module are around 30-40% of its total production
costs including feedstock, ingot casting and wafering. Therefore, there is a substantial interest in the development of a
kerf-loss free and thus cost-saving silicon wafer production. One method amongst various technologies for direct wafer
production is the Direct-Cast Silicon (DCS) process. In this wafer casting process, molten silicon is directly crystallized
on a re-usable substrate. The exploration of the solar cell efficiency potential and the characterization of DCS wafer
material are of immanent relevance for future development of the DCS technology. A high efficiency solar cell process,
developed for defect-rich multicrystalline silicon material at the University of Konstanz, was applied on DCS wafers. IV
measurements, Light Beam Induced Current (LBIC) and electroluminescence (EL) were performed. The goal was to gain
insight into the material quality and material properties, and to provide feedback for wafer production. Thereby, with
16.0%, the highest solar cell efficiency for this material could be obtained so far.

description: A single-wall carbon nanotube possesses two different types of plasmons specified by the wavenumbers in the azimuthal and axial directions. The azimuthal plasmon that is caused by interband transitions has been studied, while the effect of charge doping is unknown. In this paper, we show that when nanotubes are heavily doped, intraband transitions cause the azimuthal plasmons to appear as a plasmon resonance in the near-infrared region of the absorption spectra, which is absent for light doping due to the screening effect. The axial plasmons that are inherent in the cylindrical waveguide structures of nanotubes, account for the absorption peak of the metallic nanotube observed in the terahertz region. The excitation of axial (azimuthal) plasmons requires a linearly polarized light parallel (perpendicular) to the tube's axis.

description: In the accretion-driven growth scenario, part of the intracluster light is formed in the group environment. We report the serendipitous discovery of a group of galaxies with signs of diffuse light in the foreground of the known galaxy cluster MACS J0329-0211 at z=0.45. Our investigation began with the detection of diffuse light streams around a pair of bright galaxies in the southeastern region of a Suprime-Cam image of the galaxy cluster MACS J0329-0211. Our analysis is based on the extended CLASH-VLT redshift catalog and on new spectroscopic data obtained ad hoc with the Italian Telescopio Nazionale Galileo. We use the density reconstruction method to analyze the redshift distribution of the galaxies in the region around the galaxy pair. We also use available photometric and X-ray data to better characterize the properties of the group. Thanks to the large amount of redshift data collected in this region, we have been able to discover the existence of a group of galaxies, here called GrG J0330-0218, which is associated with the pair of galaxies. These are the two brightest group galaxies (BGG1 and BGG2). We extracted 41 group members from the redshift catalog and estimate a mean redshift z=0.1537 and a line-of-sight velocity dispersion sigmav=370 km/s. In the phase-space diagram, the distribution of the galaxies of GrG J0330-0218 follows the characteristic trumpet-shaped pattern, which is related to the escape velocity of galaxy clusters, suggesting that the group is a virialized structure. Under this assumption, the mass of the group is M200 about 6E13 Msun. We also measured a mass-to-light ratio of 130 Msun/Lsun and a luminosity fraction of diffuse light of about 20% within 0.5 R200. We conjecture that galaxy pairs that are surrounded by diffuse light, probably due to tidal interactions, can serve as signposts for groups.

description: A cost-effective method for passivation of boron diffused p+ silicon surfaces using standard industrial
inline plasma-enhanced chemical vapour deposited (PECVD) silicon nitride (SiNx) films deposited on ultrathin (~0.6
nm) chemically grown silicon oxide (SiOx) is presented. Very low emitter saturation current density (J0e) values of 26
and 48 fA/cm2, respectively, are reported for 75-Ω/sq planar and textured p+ silicon, respectively. Contactless coronavoltage
measurements indicate significantly lower positive charge density Qtotal in the SiNx films when deposited on
the ultrathin SiOx, (+ 4×1011 cm-2 compared to + 11012 cm-2 for SiNx films deposited on H-terminated silicon
surfaces). In addition, the mid-gap interface defect density Dit at the Si surface was found to be ~2×1011 eV-1cm-2 for
SiNx films deposited on the ultrathin SiOx, compared to ~7×1011 eV-1cm-2 for SiNx films deposited on H-terminated
silicon. From advanced numerical modelling, the electron surface recombination velocity parameter Sn0 at the heavily
boron doped surface is extracted to be 450 cm/s. In the case of p+ silicon surface passivation, positive fixed charge
densities of up to 8×1011 cm-2 can be tolerated, provided that the mid-gap Dit value is of the order of 1011 eV-1cm-2.
From measurements and numerical simulations we explain the surface passivation mechanism of the fabricated
samples to be completely ruled by chemical passivation (i.e., negligible field-effect passivation).

description: This work focuses on the orthogonal substrate functionalization by using parallel, additive contact lithography. Orthogonal functionalization of substrates patterned by capillary stamping may yield functional hybrid layers, in which the properties of the stamped pattern and the second component can be coupled. The coupling of functional films can lead to both additive and synergistic effects, allowing the properties of the hybrid film to be targeted for specific applications. Three different examples were investigated for this purpose. Lithiumniobate (LiNbO3), nickel ferrite (Ni2Fe4O4), and poly(2-(methacryloyloxy)ethyl ferrocenecarboxylate) (PFcMA) were each stamped and orthogonally functionalized with various components. While the stamping of LiNbO3 on previously developed stamping techniques, the other two examples involve new developed stamping techniques such as solvothermal stamping and stamping from polymer melts. Microstructured LiNbO3 holey films were generated by direct stamping with a polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) stamp an aqueous solution of lithium acetate (C2H3LiO2) and niobium oxalate hydrate (C10H5NbO2 • 6 (H2O)). Calcination of the stamped precursor film on ITO resulted in pure LiNbO3 without any impurities. Orthogonal modification of the LiNbO3-film with gold nanoparticles via electrodeposition at the positions of the macropores increased the intensity of the second harmonic output by a factor of 5.4. Capillary imprinting with DNHG-derived aerogel stamps combined with a solvothermal synthesis based on ethanol solutions of iron(III) acetylacetonate (Fe(C5H7O2)3) and nickel(II) acetylacetonate (C10H14NiO4) yielded submicron arrays of nickel ferrite dots on indium tin oxide (ITO) substrates. Then, the ITO substrates functionalized with ordered monolayers of submicron nickel ferrite dots were further orthogonally functionalized with metallic nickel by electrodeposition. The submicron nickel ferrite dots reduced the remanence of the ferromagnetic nickel film by half, while the saturation value of the magnetic moment per area remained largely constant. Furthermore, hybrid stamps made of Ni/MnO2 were generated for capillary microstamping of the stimuli-responsive ferrocene-containing polymer (PFcMA) blended with multiwalled carbon nanotubes (CNTs) from the melt. Electrochemical WCA switching reversibly transformed the PFcMA-CNT hybrid microdots from a high-WCA state, in which the PFcMA is reduced, to a low-WCA state, in which the PFcMA is oxidized (the ferrocene units are positively charged), and vice versa. Orthogonal substrate functionalization of the areas around the PFcMA-CNT hybrid microdots shifted the WCA switching range by nearly 50°.

description: We present global 3D radiation magnetohydrodynamical simulations of accretion onto a 6.62 solar mass black hole with quasi-steady state accretion rates reaching 0.016 to 0.9 times the critical accretion rate, which is defined as the accretion rate to power the Eddington luminosity assuming a 10% radiative efficiency, in different runs. The simulations show no sign of thermal instability over hundreds of thermal timescales at 10 $r_{\rm g}$. The energy dissipation happens close to the mid-plane in the near-critical runs and near the disk surface in the low accretion rate run. The total radiative luminosity inside $\sim$20 $r_{\rm g}$ is about 1% to 30% the Eddington limit, with a radiative efficiency of about 6% and 3%, respectively, in the sub- and near-critical accretion regimes. In both cases, self-consistent turbulence generated by the magnetorotational instability (MRI) leads to angular momentum transfer, and the disk is supported by magnetic pressure. Outflows from the central low-density funnel with a terminal velocity of $\sim$0.1$c$ are seen only in the near-critical runs. We conclude that these magnetic pressure dominated disks are thermally stable and thicker than the $α$ disk, and the effective temperature profiles are much flatter than that in the $α$ disks. The magnetic pressure of these disks are comparable within an order of magnitude with the previous analytical magnetic pressure dominated disk model.
