description: We explore the ability of four different inverse population synthesis codes to recover the physical properties of galaxies from their spectra by SED fitting. Three codes, DynBaS, TGASPEX, and GASPEX, have been implemented by the authors and are described in detail in the paper. STARLIGHT, the fourth code, is publicly available. DynBaS selects dynamically a different spectral basis to expand the spectrum of each target galaxy; TGASPEX uses an unconstrained age basis, whereas GASPEX and STARLIGHT use for all fits a fixed spectral basis selected a priori by the code developers. Variable and unconstrained basis reflect the peculiarities of the fitted spectrum and allow for simple and robust solutions to the problem of extracting galaxy parameters from spectral fits. We assemble a Synthetic Spectral Atlas of Galaxies (SSAG), comprising 100,000 galaxy spectra corresponding to an equal number of star formation histories based on the recipe of Chen et al. (2012). We select a subset of 120 galaxies from SSAG with a colour distribution similar to that of local galaxies in the seventh data release (DR7) of the Sloan Digital Sky Survey (SDSS) and produce 30 random noise realisations for each of these spectra. For each spectrum we recover the mass, mean age, metallicity, internal dust extinction, and velocity dispersion characterizing the dominant stellar population in the problem galaxy. All methods produce almost perfect fits to the target spectrum, but the recovered physical parameters can differ significantly. Our tests provide a quantitative measure of the accuracy and precision with which these parameters are recovered by each method. From a statistical point of view all methods yield similar precisions, whereas DynBaS produces solutions with minimal systematic biases in the distributions of residuals for all of these parameters.

description: We present a fast spectral algorithm for community detection in complex networks. Our method searches for the partition with the maximum value of the modularity via the interplay of several refinement steps that include both agglomeration and division. We validate the accuracy of the algorithm by applying it to several real-world benchmark networks. On all these, our algorithm performs as well or better than any other known polynomial scheme. This allows us to extensively study the modularity distribution in ensembles of Erdős-Rényi networks, producing theoretical predictions for means and variances inclusive of finite-size corrections. Our work provides a way to accurately estimate the effect size of modularity, providing a $z$-score measure of it and enabling a more informative comparison of networks with different numbers of nodes and links.

Geometrical approach to bosonization of D>1 dimensional (non)-Fermi liquids
Creators: name: Khveshchenko, D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: We discuss an approach to higher-dimensional bosonization of interacting fermions based on a picture of fluctuating Fermi surface. Compared with the linearized ''constructive'' approach this method allows an account of the Fermi surface curvature due to non-Gaussian terms in the bosonized Lagrangian. On the basis of this description we propose a procedure of calculating density response functions beyond the random-phase approximation (RPA). We also formulate a bosonic theory of the compressible metal-like state at the half-filled lowest Landau level and check that in the Gaussian approximation it reproduces RPA results of the gauge theory by Halperin, Lee, and Read.
Eikonal approximation in the theory of two-dimensional fermions with long-range current-current interactions

description: We study the behavior of response functions of two-dimensional (2D) fermions interacting via a long-range transverse gauge field in the eikonal approximation. We observe that an exponentially vanishing wave-function renormalization prevents divergences in the density-density correlation function and the pairing susceptibility. The wave-function renormalization also shows up in a suppression of the dHvA effect. Elaborating on an observation recently made by Ioffe, Lidsky, and Altschuler, we also infer an effective bosonic description which makes it possible to reproduce our eikonal results in terms of free 2D bosons.

description: Presentation of Case: A 71 year old female developed end stage kidney disease in the context of a pulmonary renal presentation of anti-MPO microscopic polyangiitis (MPA) 5 years prior to presentation. After induction treatment with plasma exchange, iv cyclophosphamide and corticosteroids she remained dialysis dependent. Initially ANCA negative post-induction, her anti-MPO titre fluctuated at a low titre in the intervening years without clinically active disease. Immunosuppression with prednisolone and azathioprine was withdrawn at 2 years and she was active on the deceased donor kidney transplant waiting list. She presented with lower back and hip pain and was evaluated. Diagnostic Testing: Cross sectional imaging revealed an expansile mass in the right pelvic bone and a 6cm right kidney lesion. A biopsy of the pelvic lesion revealed a clear cell renal cell carcinoma (IMDC Score 3). Serological assays demonstrated a > 4 fold rise in her anti-MPO titre in the 6 months prior to presentation. Following a multi-disciplinary review that noted the theoretical potential for MPA relapse she was initiated on Ipilinumab (anti-CTLA4 ) and Nivolumab (Anti-PD1) immunotherapy. Within one week the patient developed malaise, arthralgia, a purpuric lower extremity rash and epistaxis. Her CRP climbed from 20mg/L to 100mg/L. Differential & Final Diagnosis: The presumptive diagnosis was a rapid relapse of her MPA consequent to dual pathway checkpoint inhibition. Discussion of Management: Nivolumab and Ipilinumab therapy was withdrawn and the patient was treated with 40mg of prednisolone daily. The rash, epistaxis and systemic symptoms abated within days. Conclusions: Recent experimental and genetic studies have implicated the role of programmed cell death protein 1 (PD-1), programmed cell death protein-ligand 1 (PDL-1), and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) in the pathogenesis of medium and large vessel vasculitis. This case suggests a key role the PD1-PDL1 and CTLA4-CD80/86 pathways in the down regulating of anti-MPO antibody responses in small vessel vasculitis in vivo. This case highlights the potential for checkpoint inhibition to cause disease relapse but also point to the potential for harnessing these pathways for novel disease modifying therapies in the future.

description: We present black hole mass measurements from kinematic modeling of high-spatial resolution integral field spectroscopy of the inner regions of 9 nearby (ultra-)luminous infrared galaxies in a variety of merger stages. These observations were taken with OSIRIS and laser guide star adaptive optics on the Keck I and Keck II telescopes, and reveal gas and stellar kinematics inside the spheres of influence of these supermassive black holes. We find that this sample of black holes are overmassive ($\sim10^{7-9}$ M$_{Sun}$) compared to the expected values based on black hole scaling relations, and suggest that the major epoch of black hole growth occurs in early stages of a merger, as opposed to during a final episode of quasar-mode feedback. The black hole masses presented are the dynamical masses enclosed in $\sim$25pc, and could include gas which is gravitationally bound to the black hole but has not yet lost sufficient angular momentum to be accreted. If present, this gas could in principle eventually fuel AGN feedback or be itself blown out from the system.

description: Existing methods for nonlinear robust control often use scenario-based approaches to formulate the control problem as large nonlinear optimization problems. The optimization problems are challenging to solve due to their size, especially if the control problems include time-varying uncertainty. This paper draws from local reduction methods used in semi-infinite optimization to solve robust optimal control problems with parametric and time-varying uncertainty. By iteratively adding interim worst-case scenarios to the problem, methods based on local reduction provide a way to manage the total number of scenarios. We show that the local reduction method for optimal control problems consists of solving a series of simplified optimal control problems to find worst-case constraint violations. In particular, we present examples where local reduction methods find worst-case scenarios that are not on the boundary of the uncertainty set. We also provide bounds on the error if local solvers are used. The proposed approach is illustrated with two case studies with parametric and additive time-varying uncertainty. In the first case study, the number of scenarios obtained from local reduction is 101, smaller than in the case when all $2^{14+3\times192}$ extreme scenarios are considered. In the second case study, the number of scenarios obtained from the local reduction is two compared to 512 extreme scenarios. Our approach was able to satisfy the constraints both for parametric uncertainty and time-varying disturbances, whereas approaches from literature either violated the constraints or became computationally expensive.

description: In this paper the smallest thermal screening mass associated with the correlator of the $CT$-odd operator, $\sim {\rm Tr}F_{μν}\tilde{F}^{μν}$, is determined in strongly coupled non-Abelian gauge plasmas which are holographically dual to non-conformal, bottom-up Einstein+scalar gravity theories. These holographic models are constructed to describe the thermodynamical properties of $SU(N_c)$ plasmas near deconfinement at large $N_c$ and we identify this thermal mass with the Debye screening mass $m_D$. In this class of non-conformal models with a first order deconfinement transition at $T_c$, $m_D/T$ displays the same behavior found for the expectation value of the Polyakov loop (which we also compute) jumping from zero below $T_c$ to a nonzero value just above the transition. In the case of a crossover phase transition, $m_D/T$ has a minimum similar to that found for the speed of sound squared $c_s^2$. This holographic framework is also used to evaluate $m_D$ as a function of $η/s$ in a strongly coupled conformal gauge plasma dual to Gauss-Bonnet gravity. In this case, $m_D/T$ decreases with increasing $η/s$ in accordance with extrapolations from weak coupling calculations.

description: We present a novel approach for the dimensionality reduction of galaxy images by leveraging a combination of variational auto-encoders (VAE) and domain adaptation (DA). We demonstrate the effectiveness of this approach using a sample of low redshift galaxies with detailed morphological type labels from the Galaxy-Zoo DECaLS project. We show that 40-dimensional latent variables can effectively reproduce most morphological features in galaxy images. To further validate the effectiveness of our approach, we utilised a classical random forest (RF) classifier on the 40-dimensional latent variables to make detailed morphology feature classifications. This approach performs similarly to a direct neural network application on galaxy images. We further enhance our model by tuning the VAE network via DA using galaxies in the overlapping footprint of DECaLS and BASS+MzLS, enabling the unbiased application of our model to galaxy images in both surveys. We observed that DA led to even better morphological feature extraction and classification performance. Overall, this combination of VAE and DA can be applied to achieve image dimensionality reduction, defect image identification, and morphology classification in large optical surveys.

description: Presentation of Case: A 63-year-old female presented with PMR with CRP 37mg/L and ESR 80mm/hr. Prednisolone 15mg resulted in a marked response. On weaning prednisolone to 10mg she developed headaches, scalp tenderness, jaw claudication and diplopia prompting an increase of prednisolone to 60mg. Diagnostic testingTemporal artery biopsy was in keeping with GCA (Fig. 1A&B). Her headaches settled, but she developed rhinnorhoea, epistaxis, vasculitic rash and shortness-of-breath. Urinalysis demonstrated no casts. Chest-Xray revealed right-sided consolidation (Fig. 1C) and CT sinuses confirmed mucosal thickening (Fig. 1D). Inflammatory markers remained elevated ESR 39mm/hr and CRP 59mg/L with a normal creatinine 71µmol/L [62-124]. Differentail and final diagnsosis C-ANCA was positive with PR3 114 IU/ml [0-3.1] confirming the diagnosis of GPA. Nasal biopsy demonstrated inflammation without granulomatous changes. She received prednisolone 1mg/Kg and intravenous Cyclophosphamide. Azathioprine maintenance was initiated once she was in remission. Discossion of management Our case highlights GPA can present with features typical of GCA. This is important as the treatment and prognosis are different with systemic steroids usually sufficient to treat GCA, but GPA requires additional Cyclophosphamide or Rituximab therapy. Conclusion: Large vessel vasculitis [LVV] can be a feature of GPA and may affect aorta, subclavians or carotid arteries. LVV often presents at the time of initial diagnosis of GPA, but may precede or occur after the GPA diagnosis [1, 2]. Disclosures: None
Absence of Josephson coupling between certain superconductors

description: It is generally believed that superconductivity can occur in materials irrespective of whether the charge carriers in the material are electrons or holes. Here we point out that Josephson tunneling would not occur between superconductors with charge carriers of opposite sign. Consequently, observation of Josephson tunneling between two superconductors implies that their charge carriers have the same sign. We propose that this has profound implications for the understanding of superconductivity and in particular is consistent with the theory of hole superconductivity.

description: Simulating the real-time dynamics of lattice gauge theories, underlying the Standard Model of particle physics, is a notoriously difficult problem where quantum simulators can provide a practical advantage over classical approaches. In this work, we present a complete Rydberg-based architecture, co-designed to digitally simulate the dynamics of general gauge theories coupled to matter fields in a hardware-efficient manner. Ref. [1] showed how a qudit processor, where non-abelian gauge fields are locally encoded and time-evolved, considerably reduces the required simulation resources compared to standard qubit-based quantum computers. Here we integrate the latter with a recently introduced fermionic quantum processor [2], where fermionic statistics are accounted for at the hardware level, allowing us to construct quantum circuits that preserve the locality of the gauge-matter interactions. We exemplify the flexibility of such a fermion-qudit processor by focusing on two paradigmatic high-energy phenomena. First, we present a resource-efficient protocol to simulate the Abelian-Higgs model, where the dynamics of confinement and string breaking can be investigated. Then, we show how to prepare hadrons made up of fermionic matter constituents bound by non-abelian gauge fields, and show how to extract the corresponding hadronic tensor. In both cases, we estimate the required resources, showing how quantum devices can be used to calculate experimentally-relevant quantities in particle physics.

With strong, frequent and persistent katabatic winds occurring year long, the measurement area is among the most prone to snow transport by wind on the ice sheet. Available data collected almost continuously at a half-hourly resolution at two locations 100 km apart include 2-m wind speed and direction, 2-m air temperature, 2-m air relative humidity with respect to ice and drifting snow mass fluxes. The data files contain the following variables and units: YYYY: year; MM: month; DD: day; hh: hour; mm: minute; U2m: 2-m wind speed (m/s): zU: actual height of the anemometer (m); T2m: 2-m air temperature (° C); RH2m: 2-m air relative humidity (% w.r.i.); zT: actual height of the thermo-hygrometer (m); FC1: drifting snow flux from lower level (g m-2 s-1); FC2: drifting snow flux from upper level (g m-2 s-1); zFC1: actual top height above ground of the lower FlowCapt sensor (m).

description: Our overall goal is to unify and extend some results in the literature related to the approximation of generating functions of finite and infinite sequences over a field by rational functions. In our approach, numerators play a significant role. We revisit a theorem of Niederreiter on (i) linear complexities and (ii) '$n^{th}$ minimal polynomials' of an infinite sequence, proved using partial quotients. We prove (i) and its converse from first principles and generalise (ii) to rational functions where the denominator need not have minimal degree. We prove (ii) in two parts: firstly for geometric sequences and then for sequences with a jump in linear complexity. The basic idea is to decompose the denominator as a sum of polynomial multiples of two polynomials of minimal degree; there is a similar decomposition for the numerators. The decomposition is unique when the denominator has degree at most the length of the sequence. The proof also applies to rational functions related to finite sequences, generalising a result of Massey. We give a number of applications to rational functions associated to sequences.

description: Simulations of lattice gauge theories with tensor networks and quantum computing have so far mainly focused on staggered fermions. In this paper, we use matrix product states to study Wilson fermions in the Hamiltonian formulation and present a novel method to determine the additive mass renormalization. Focusing on the single-flavor Schwinger model as a benchmark model, we investigate the regime of a nonvanishing topological $θ$-term, which is inaccessible to conventional Monte Carlo methods. We systematically explore the dependence of the mass shift on the volume, the lattice spacing, the $θ$-parameter, and the Wilson parameter. This allows us to follow lines of constant renormalized mass, and therefore to substantially improve the continuum extrapolation of the mass gap and the electric field density. For small values of the mass, our continuum results agree with the theoretical prediction from mass perturbation theory. Going beyond Wilson fermions, our technique can also be applied to staggered fermions, and we demonstrate that the results of our approach agree with a recent theoretical prediction for the mass shift at sufficiently large volumes.

For the class C ensemble we derive a more explicit representation of the j.p.d.f. which results in a new type of random matrix model.

description: The design and engineering of molecular communication (MC) components capable of processing chemical concentration signals is the key to unleashing the potential of MC for interdisciplinary applications. By controlling the signaling pathway and molecule exchange between cell devices, synthetic biology provides the MC community with tools and techniques to achieve various signal processing functions. In this paper, we propose a design framework to realize any order concentration shift keying (CSK) systems based on simple and reusable single-input single-output cells. The design framework also exploits the distributed multicellular consortia with spatial segregation, which has advantages in system scalability, low genetic manipulation, and signal orthogonality. We also create a small library of reusable engineered cells and apply them to implement binary CSK (BCSK) and quadruple CSK (QCSK) systems to demonstrate the feasibility of our proposed design framework. Importantly, we establish a mathematical framework to theoretically characterize our proposed distributed multicellular systems. Specially, we divide a system into fundamental building blocks, from which we derive the impulse response of each block and the cascade of the impulse responses leads to the end-to-end response of the system. Simulation results obtained from the agent-based simulator BSim not only validate our CSK design framework but also demonstrate the accuracy of the proposed mathematical analysis.

description: High resolution spectroscopy with the Subaru High Dispersion Spectrograph, and Swift ultraviolet photometry are presented for the pulsating extreme helium star V652\,Her. Swift provides the best relative ultraviolet photometry obtained to date, but shows no direct evidence for a shock at ultraviolet or X-ray wavelengths. Subaru has provided high spectral and high temporal resolution spectroscopy over 6 pulsation cycles (and eight radius minima). These data have enabled a line-by-line analysis of the entire pulsation cycle and provided a description of the pulsating photosphere as a function of optical depth. They show that the photosphere is compressed radially by a factor of at least two at minimum radius, that the phase of radius minimum is a function of optical depth and the pulse speed through the photosphere is between 141 and 239 km/s (depending how measured) and at least ten times the local sound speed. The strong acceleration at minimum radius is demonstrated in individual line profiles; those formed deepest in the photosphere show a jump discontinuity of over 70 km/s on a timescale of 150 s. The pulse speed and line profile jumps imply a shock is present at minimum radius. These empirical results provide input for hydrodynamical modelling of the pulsation and hydrodynamical plus radiative transfer modelling of the dynamical spectra.

description: Analytical solutions of the Schrödinger equation for the one-dimensional quantum well with all possible permutations of the Dirichlet and Neumann boundary conditions (BCs) in perpendicular to the interfaces uniform electric field $\mathscr{E}$ are used for the comparative investigation of their interaction and its influence on the properties of the system. Limiting cases of the weak and strong voltages allow an easy mathematical treatment and its clear physical explanation; in particular, for the small $\mathscr{E}$, the perturbation theory derives for all geometries a linear dependence of the polarization on the field with the BC-dependent proportionality coefficient being positive (negative) for the ground (excited) states. Simple two-level approximation elementary explains the negative polarizations as a result of the field-induced destructive interference of the unperturbed modes and shows that in this case the admixture of only the neighboring states plays a dominant role. Different magnitudes of the polarization for different BCs in this regime are explained physically and confirmed numerically. Hellmann-Feynman theorem reveals a fundamental relation between the polarization and the speed of the energy change with the field. It is proved that zero-voltage position entropies $S_x$ are BC independent and for all states but the ground Neumann level (which has $S_x=0$) are equal to $\ln2-1$ while the momentum entropies $S_k$ depend on the edge requirements and the level. Varying electric field changes position and momentum entropies in the opposite directions such that the entropic uncertainty relation is satisfied.

description: Applying the transformation of fermion operators to the fermion quasiparticles introduced by Halperin, Lee, and Read, we estimate the scaling behavior of the ground-state energy and quasiparticle gaps as a function of filling fraction for a ''principal sequence'' of fractional-quantum-Hall-effect ν=N/(2N±1) states converging towards the gapless state at half filling. The exponent describing the shape of the cusp δE(ν)∼δνη is found to be greater than 1 and to depend nontrivially on the interaction potential. The dependence of quasiparticle gaps agrees with the results of recent measurements by R. R. Du et al.

description: Presentation of Case: We present two cases of antineutrophil cytoplasmic autoantibody (ANCA)–associated vasculitis (AAV). The first was an 86-year-old woman with known bronchiectasis, seronegative inflammatory oligoarthiritis and polymyalgia rheumatic who presented with COVID-19 infection and developed diffuse alveolar hemorrhage with severe hypoxemia. The second case was a previously healthy 60-year-old female who developed dyspnea, weight loss and mononeuropathy with multiple granulomatous pulmonary nodules shortly after COVID-19 vaccination. Diagnostic Testing: The first case was found to be positive for perinuclear-ANCA and myeloperoxidase (MPO) antibodies. The second case underwent computed tomography-guided lung biopsy which showed acute necrotizing granulomatous inflammation without active infection. She was also strongly positive for proteinase 3 (PR3)-ANCA. Differential & Final Diagnosis: Case 1 was unable to undergo bronchoscopy due to do-not-intubate status. It was thought that this was truly a new case of vasculitis given that she had previously undergone a workup with negative ANCA antibodies. She was empirically treated with high dose steroids and convalescent plasma with clinical and radiographic improvement. Given the persistently positive antibodies months after hospitalization, she was started on rituximab and then methotrexate which could not be tolerated. Case 2 was diagnosed on granulomatosis with polyangiitis and initiated on prednisone with subsequent rituximab resulting in clinical and radiological improvement. Discussion of Management: Any inflammatory process can lead to AAV although the causes are vast and can be from infection, genetic predisposition or medication.1,2 AAV may occur with COVID-19 antigenic exposure, either from infection or immunization, although the risk after vaccination is rare and less common than that associated with other immunizations.1,3,4 It was felt to be necessary to wait to administer Rituximab until after the patients had mounted an appropriate antibody response. A prior study did not show worse outcomes for patients with rheumatologic diseases taking immunosuppressants who developed COVID-19 infection, but another study showed more severe disease.5,6 Conclusions: Although rare, AAV can be associated with COVID-19 antigenic exposure after infection or immunization. Early diagnosis of AAV is important as immunosuppressive therapy may improve outcomes. Disclosures: None

description: We investigated the effect of Dibucaine hydrochloride (DC$\cdot$HCl), one of the local anesthetics, on phase behavior of ternary liposome composed of dioleoylphosphatidylcholine (DOPC), dipalmitoylphosphatidylcholine (DPPC), and cholesterol (Chol). The large DOPC/DPPC/Chol liposome, that is directly observable by optical microscope, is commonly known to be laterally separated into liquid-ordered (Lo) phase (raft-like domain) and liquid-disordered (Ld) phase under certain conditions and is useful for study of lipid-raft-like domains as a simple model system. In order to confirm the effect of DC$\cdot$HCl on a miscibility transition temperature, $T_{\rm c}$, of the ternary liposome, we observed the liposomes with three concentrations, 0, 0.05, and 0.2~mM, of DC$\cdot$HCl at various temperatures. In addition, we calculated the angle-averaged two-dimensional autocorrelation (2D-AC) functions in order to quantify the phase behavior. The results of these observations and calculations revealed that the DC$\cdot$HCl molecules induce the reduction of $T_{\rm c}$ of the ternary liposome. Furthermore, we calculated the circularity of Lo domain in order to confirm the change in the line tension of the Lo/Ld phase boundary and revealed that the insertion of the DC molecules induces the reduction of line tension. In terms of the critical phenomena, we conclude that the insertion of the DC molecules induces the reduction of the $T_{\rm c}$ of the ternary liposome due to reduction of line tension. This suggests that the DC molecules may disturb function of ion channels via affecting the lipid bilayers which surround ion channels.

Abstract An oral fixed-dose combination of relugolix/estradiol/norethisterone (also known as norethindrone) acetate ( Ryeqo®; Myfembree ®) has been approved for the management of heavy menstrual bleeding associated with uterine fibroids in the USA and management of moderate to severe symptoms of uterine fibroids in the EU. Relugolix is a gonadotropin releasing hormone (GnRH) receptor antagonist that decreases serum estradiol and progesterone concentrations to postmenopausal levels. The addition of estradiol/norethisterone acetate to relugolix ameliorates relugolix-induced bone loss and hot flush. In the two phase 3 LIBERTY trials, relugolix + estradiol/norethisterone substantially decreased menstrual bleeding and improved a range of other uterine fibroid symptoms in women with uterine fibroids-associated heavy menstrual bleeding. The combination was generally well tolerated, with vasomotor symptoms being the most common adverse reaction. Treatment with this combination for over up to 2 years did not induce a clinically meaningful bone loss in the majority of women. Relugolix/estradiol/norethisterone acetate, with its convenient once-daily administration, is a useful addition to current pharmacological treatment options for premenopausal women with symptomatic uterine fibroids.

Bosonization of current-current interactions
Creators: name: Khveshchenko, D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: We discuss a generalization of the conventional bosonization procedure to the case of current-current interactions which have a natural representation in terms of current instead of fermion-number-density operators. A consistent bosonization procedure requires a geometrical quantization of the Hamiltonian action of W on its coadjoint orbits. An integrable example of a nontrivial realization of this symmetry is presented by the Calogero-Sutherland model. For an illustrative nonintegrable example we consider transverse gauge interactions and calculate the fermion Green function.
Disk Winds as an Explanation for Slowly Evolving Temperatures in Tidal Disruption Events

description: Among the many intriguing aspects of optically discovered tidal disruption events (TDEs) is that their temperatures are lower than expected and that the temperature does not evolve as rapidly with decreasing fallback rate as would be expected in standard disk theory. We show that this can be explained qualitatively using an idea proposed by Laor & Davis in the context of normal active galactic nuclei: that larger accretion rates imply stronger winds and thus that the accretion rate through the inner disk only depends weakly on the inflow rate at the outer edge of the disk. We also show that reasonable quantitative agreement with data requires that, as has been suggested in recent papers, the circularization radius of the tidal stream is approximately equal to the semimajor axis of the most bound orbit of the debris rather than twice the pericenter distance as would be expected without rapid angular momentum redistribution. If this explanation is correct, it suggests that the evolution of TDEs may test both non-standard disk theory and the details of the interactions of the tidal stream.

description: Affine quantization is a relatively new procedure, and it can solve many new problems. This essay reviews this new, and novel, procedure for particle problems, as well as those of fields and gravity. New quantization tools, which are extremely close to, and even constructed from, the tools of canonical quantization, are able to fully solve selected problems that using the standard canonical quantization would fail. In particular, improvements can even be found with an affine quantization of fields, as well as gravity.

description: By means of density functional theory calculations, we predict that several two dimensional AB binary monolayers, where A and B atoms belong to group IV or III-V, are ferroelectric. Dipoles arise from the buckled structure, where the A and B ions are located on the sites of a bipartite corrugated honeycomb lattice with trigonal symmetry. We discuss the emerging valley-dependent properties and the coupling of spin and valley physics, which arise from the loss of inversion symmetry, and explore the interplay between ferroelectricity and Rashba spin-spitting phenomena. We show that valley-related properties originate mainly from the binary nature of AB monolayers, while the Rashba spin-texture developing around valleys is fully controllable and switchable by reversing the ferroelectric polarization.

description: Deep learning models have provided huge interpretation power for image-like data. Specifically, convolutional neural networks (CNNs) have demonstrated incredible acuity for tasks such as feature extraction or parameter estimation. Here we test CNNs on strong-field ionization photoelectron spectra, training on theoretical data sets to `invert' experimental data. Pulse characterization is used as a `testing ground', specifically we retrieve the laser intensity, where `traditional' measurements typically lead to 20% uncertainty. We report on crucial data augmentation techniques required to successfully train on theoretical data and return consistent results from experiments, including accounting for detector saturation. The same procedure can be repeated to apply CNNs in a range of scenarios for strong-field ionization. Using a predictive uncertainty estimation, reliable laser intensity uncertainties of a few percent can be extracted, which are consistently lower than those given by traditional techniques. Using interpretability methods can reveal parts of the distribution that are most sensitive to laser intensity, which can be directly associated with holographic interferences. The CNNs employed provide an accurate and convenient ways to extract parameters, and represent a novel interpretational tool for strong-field ionization spectra.
