description: Artificial intelligence (AI) solutions that automatically extract information from digital histology images have shown great promise for improving pathological diagnosis. Prior to routine use, it is important to evaluate their predictive performance and obtain regulatory approval. This assessment requires appropriate test datasets. However, compiling such datasets is challenging and specific recommendations are missing. A committee of various stakeholders, including commercial AI developers, pathologists, and researchers, discussed key aspects and conducted extensive literature reviews on test datasets in pathology. Here, we summarize the results and derive general recommendations for the collection of test datasets. We address several questions: Which and how many images are needed? How to deal with low-prevalence subsets? How can potential bias be detected? How should datasets be reported? What are the regulatory requirements in different countries? The recommendations are intended to help AI developers demonstrate the utility of their products and to help regulatory agencies and end users verify reported performance measures. Further research is needed to formulate criteria for sufficiently representative test datasets so that AI solutions can operate with less user intervention and better support diagnostic workflows in the future.

description: Solitary stars that wander too close to their galactic centres can become tidally disrupted, if the tidal forces due to the supermassive black hole (SMBH) residing there overcome the self-gravity of the star. If the star is only partially disrupted, so that a fraction survives as a self-bound object, this remaining core will experience a net gain in specific orbital energy, which translates into a velocity "kick" of up to $\sim 10^3$ km/s. In this paper, we present the result of smoothed particle hydrodynamics (SPH) simulations of such partial disruptions, and analyse the velocity kick imparted on the surviving core. We compare $γ$ = 5/3 and $γ$ = 4/3 polytropes disrupted in both a Newtonian potential, and a generalized potential that reproduces most relativistic effects around a Schwarzschild black hole either exactly or to excellent precision. For the Newtonian case, we confirm the results of previous studies that the kick velocity of the surviving core is virtually independent of the ratio of the black hole to stellar mass, and is a function of the impact parameter $β$ alone, reaching at most the escape velocity of the original star. For a given $β$, relativistic effects become increasingly important for larger black hole masses. In particular, we find that the kick velocity increases with the black hole mass, making larger kicks more common than in the Newtonian case, as low-$β$ encounters are statistically more likely than high-$β$ encounters. The analysis of the tidal tensor for the generalized potential shows that our results are robust lower limits on the true relativistic kick velocities, and are generally in very good agreement with the exact results.

description: Die Masterarbeit beschäftigt sich mit dem audiovisuellen Format Visual Album und dessen kritischen Potenzial. An der Schnittstelle von Film und Musikvideo deckt das es neue Denk- und Funktionsweisen audiovisueller Medien auf. Ziel der vorliegenden Arbeit ist es, formal-ästhetische und inhaltliche Strategien der Selbstermächtigung anhand vom Fallbeispiel When I Get Home von Solange (R: Solange Knowles et al., US 2019) zu untersuchen. Als Visual Album einer Schwarzen Musikerin adressiert es auf direkte wie subversive Weise Themen um geschlechterspezifische Diskriminierung und rassistische Darstellungsweisen in klassischen audiovisuellen Medien. Wichtige theoretische Konzepte zur Thematik von Musikvideoanalyse und alternativen Formaten, sowie feministische und intersektionale Perspektiven und Theorien zum Stilmittel Afro-Surrealismus werden dabei zu Rate gezogen. Die Arbeit macht sich zudem zur Aufgabe, die bisher wenig untersuchte Gattung Visual Album in den Fokus zu rücken und in einem Charakterisierungsversuch den Begriff zu schärfen, indem zentrale formaler Eigenschaften des jungen Formats definiert werden.
description: The master’s thesis focuses on the audiovisual format visual album and its critical potential. Located at the intersection of the genres film and music video, the visual album reveals new approaches on thinking and functionality of traditional audiovisual media. The work’s aim is to examine formal-aesthetic and content-related strategies of self-empowerment using When I Get Home by Solange (D: Solange Knowles et al., US: 2019) as its case study. As a visual album written, produced, and performed by a black female musician, it directly and subversively addresses gender discrimination and racist tendencies in representations in traditional media. Important theoretical concepts on the topic of music video analysis and transforming audiovisual media, as well as feminist and intersectional perspectives and theories on the stylistic aspects of afro-surrealism are being described. The thesis also sets itself the task of focusing on the thus far scarcely studied visual album genre, and, in an attempt, to sharpen the term by defining central formal characteristics of the young format.

description: Covid-19 has grown rapidly in all parts of the world and is considered an international disaster because of its wide-reaching impact. The impact of Covid-19 has spread to Indonesia, especially in the slowdown in economic growth. This was influenced by the implementation of Community Activity Restrictions (PPKM) which limited community economic activities. This study aims to analyze the mapping of public sentiment towards PPKM policies in Indonesia during the pandemic based on Twitter data. Knowing the mapping of public sentiment regarding PPKM is expected to help stakeholders in the policy evaluation process for each region. The method used is BERT with IndoBERT specific model. The results showed the evaluation value of IndoBERT f-1 score reached 84%, precision 86%, and recall 84%. Meanwhile for the evaluation of the use of SVM f-1 score 70%, 72% precision, and 70% recall. Multinominal Naïve Bayes evaluation shows f-1 score 83%, precision 78%, and recall 80%. As a conclusion, BERT method with the IndoBERT model is proven to be higher than classical methods such as SVM and Multinominal Naïve Bayes.

description: Dust Obscured Galaxies (DOGs), which are observationally characterized as faint in the optical and bright in the infrared, are the final stage of galaxy mergers and are essential objects in the evolution of galaxies and active galactic nuclei (AGNs). However, the relationship between torus-scale gas dynamics around AGNs and DOGs lifetime remain unclear. We obtained evolution of the spectral energy distributions (SEDs) of a galaxy merger system with AGN feedback, from post-processed pseudo-observations based on an N-body/Smoothed Particle Hydrodynamics (SPH) simulation. We focused on a late stage merger of two identical galaxies with a supermassive black hole (SMBH) of 10$^8$ M$_\odot$. We found that the infrared luminosity of the system reaches ultra- and hyper-luminous infrared galaxy classes (10$^{12}$ and 10$^{13}$ L$_\odot$, respectively). The DOGs phase corresponds to a state in which the AGNs are buried in dense gas and dust, with the infrared luminosity exceeding 3.3 $\times$ 10$^{12}$ L$_\odot$. We also identified the sub-categories of DOGs, namely bump and power-law DOGs from the SEDs and their evolution. The bump DOGs tend to evolve to power-law DOGs on several Myrs. We found that contribution from the hot dust around the nucleus in the infrared radiation is essential for identifying the system as a power-law DOG; the gas and dust distribute non-spherically around the nucleus, therefore, the observed properties of DOGs depend on the viewing angle. In our model, the lifetime of merger-driven DOGs is less than 4 Myrs, suggesting that the observed DOGs phase is a brief aspect of galaxy mergers.

description: Recently, the CDF collaboration reported a new measurement of the $W$ boson mass $M_W = 80.4335 \pm 0.0094$ GeV, which shows a $\sim 7σ$ deviation from the standard model prediction $80.3545 \pm 0.0057$ GeV obtained by the electroweak (EW) global fit. This deviation can be explained by new physics generating moderate EW oblique parameters $S$, $T$, and $U$. In this work, we use the loop corrections induced by some extra EW multiplets to explain the CDF $M_W$ anomaly. The lightest neutral particle in the multiplets can also serve as a candidate of cold dark matter (DM). We consider two such models, namely singlet-triplet scalar DM and singlet-doublet fermionic DM models, and perform numerical scans to find the parameter points accounting for the $M_W$ anomaly. The constraints from the correct DM thermal relic density and direct detection are also taken into account. We find the parameter points simultaneously interpreting the $M_W$ anomaly and satisfying the DM requirements in the former model, but do not find such parameter points in the latter model.

description: Unlocking the mystery of the strange metal state has become the focal point of high T$_{c}$ research, not because of its importance for superconductivity, but because it appears to represent a truly novel phase of matter dubbed `quantum supreme matter'. Detected originally through high magnetic field, transport experiments, signatures of this phase have now been uncovered with a variety of probes. Our high resolution optical data of the low T$_{c}$ cuprate superconductor, Bi$_{2-x}$Pb$_{x}$Sr$_{2-y}$La$_{y}$CuO$_{6+δ}$ allows us to probe this phase over a large energy and temperature window. We demonstrate that the optical signatures of the strange metal phase persist throughout the phase diagram. The strange metal signatures in the optical conductivity are two-fold, (i): a low energy Drude response with Drude width on the order of temperature and (ii): a high energy conformal tail with doping dependent power-law exponent. While the Drude weight evolves monotonously throughout the entire doping range studied, the spectral weight contained in the high energy conformal tail appears to be doping and temperature independent. Our analysis further shows that the temperature dependence of the optical conductivity is completely determined by the Drude parameters. Our results indicate that there is no critical doping level inside the superconducting dome where the carrier density starts to change drastically and that the previously observed 'return to normalcy' is a consequence of the increasing importance of the Drude component relative to the conformal tail with doping. Importantly, both the doping and temperature dependence of the resistivity are largely determined by the Drude width.

description: The compact simply connected Riemannian 4-symmetric spaces were classified by J.A. Jim{é}nez according to type of the Lie algebras. As homogeneous manifolds, these spaces are of the form $G/H$, where $G$ is a connected compact simple Lie group with an automorphism $\tildeγ$ of order four on $G$ and $H$ is a fixed points subgroup $G^γ$ of $G$. According to the classification by J.A. Jim{é}nez, there exist seven compact simply connected Riemannian 4-symmetric spaces $ G/H $ in the case where $ G $ is of type $ E_8 $. In the present article, %as Part II continuing from Part I, for the connected compact %exceptional Lie group $E_8$, we give the explicit form of automorphisms $\tildeω^{}_4,\tildeκ^{}_4$ and $ \tilde{\varepsilon}^{}_4$ of order four on $E_8$ induced by the $C$-linear transformations $ω^{}_4, κ^{}_4$ and $ \varepsilon^{}_4$ of the 248-dimensional $ C $-vector space ${\mathfrak{e}_8}^{C}$, respectively. Further, we determine the structure of these fixed points subgroups $(E_8)^{{}_{ω^{}_4}}, (E_8)^{{}_{κ^{}_4}}$ and $(E_8)^{{}_{\varepsilon^{}_4}}$ of $ E_8 $. These amount to the global realizations of three spaces among seven Riemannian 4-symmetric spaces $ G/H $ above corresponding to the Lie algebras $ \mathfrak{h}=\mathfrak{su}(2)\oplus i\mathbf{R} \oplus \mathfrak{e}_6, i\mathbf{R} \oplus \mathfrak{so}(14)$ and $\mathfrak{h} =\mathfrak{su}(2) \oplus i\mathbf{R}\oplus \mathfrak{so}(12)$, where $ \mathfrak{h}={\rm Lie}(H) $. With this article, the all realizations of inner automorphisms of order four and fixed points subgroups by them have been completed in $ E_8 $.

description: The problem of world inflation and the desire to compare our theories of inflation in open economies with the accumulating evidence prompted the sponsors to organize a conference on Bank Credit, Money and Inflation at the Katholieke Universiteit Leuven in September 1974. The papers and comments in this volume are the contributions of the conference and its principal work.

Most of the papers fall within the very broad framework known as the monetary approach to the balance of payments and inflation. The distinguishing characteristic of this approach is not a particular analytical structure or model but a set of general principles guiding research. Two principles appear to be generally and perhaps universally accepted by those who use the framework. Both are long-run propositions

description: We present the first data release of the Survey on extragALactic magnetiSm with SOFIA (SALSA Legacy Program) with a set of 14 nearby ($<20$ Mpc) galaxies with resolved imaging polarimetric observations using HAWC+ from $53$ to $214$ $μ$m at a resolution of $5-18$" ($90$ pc $-$ $1$ kpc). We introduce the definitions and background on extragalactic magnetism, and present the scientific motivation and sample selection of the program. Here, we focus on the general trends in the emissive polarization fraction. Far-infrared polarimetric observations trace the thermal polarized emission of magnetically aligned dust grains across the galaxy disks with polarization fractions of $P=0-15$% in the cold, $T_{\rm d} = [19,48]$ K, and dense, $\log_{10}(N_{\rm HI+H_{2}}) = [19.96,22.91]$, interstellar medium. The spiral galaxies show a median $\langle P_{154μm} \rangle = 3.3\pm0.9 $% across the disks. We report the first polarized spectrum of starburst galaxies showing a minimum within $89-154$ $μ$m. The falling $53-154$ $μ$m polarized spectrum may be due to a decrease in the dust grain alignment efficiency produced by variations in dust temperatures along the line-of-sight in the galactic outflow. We find that the starburst galaxies and the star-forming regions within normal galaxies have the lowest polarization fractions. We find that 50% (7 out of 14) of the galaxies require a broken power-law in the $P-N_{HI+H_{2}}$ and $P-T_{d}$ relations with three different trends. Group 1 has a relative increase of anisotropic random B-fields produced by compression or shear of B-fields in the galactic outflows, starburst rings, and inner-bar of galaxies; and Groups 2 and 3 have a relative increase of isotropic random B-fields driven by star-forming regions in the spiral arms, and/or an increase of dust grain alignment efficiency caused by shock-driven regions or evolutionary stages of a galaxy.

Cyclotron-resonance-induced negative dc conductivity in a two-dimensional electron system on liquid helium

description: We theoretically predict instability of a zero-dc-current state of the two-dimensional electron system formed on the surface of liquid helium induced by the cyclotron resonance (CR). This conclusion follows from the theoretical analysis of the dc magnetoconductivity which takes into account the contribution from radiation in an exact way. A many-electron model of the dynamic structure factor of the 2D Coulomb liquid is used to describe the influence of strong internal forces acting between electrons. For low electron densities and high amplitudes of the microwave field, the dc magnetoconductivity is shown to become negative in the vicinity of the CR which causes the instability. This effect is strongly suppressed by Coulomb forces in the region of high densities.

description: Efficient technology that requires less energy than is currently used to get the same or better output has fueled the growth of our economy for more than a century. But while America was building its infrastructure and developing its industry and service sectors, the energy intensity of the economy, BTU per dollar of output, fell dramatically. If this had not happened, it would now take four times as much petroleum, coal, and natural gas to produce current GDP, at the 1919 energy-intensity level. This would amount to 85 percent of the current world production of fossil fuels—just to support the U.S. economy. Producing, transporting, and using that much energy, even if it were technically feasible, would devastate the natural environment and contribute to carbon dioxide emissions that would exceed the atmospheric concentration some scientists think would be catastrophic.

description: Individuals with schizophrenia spectrum disorders (SSD) are at heightened risk for exposure to stressful life events which can lead to increased sensitivity to stress and a dysregulated stress response, which are in turn associated with poor long-term functioning. Stress reactivity is thus a promising treatment target in the early stages of SSD. Integrated-Coping Awareness Therapy (I-CAT) is a manualized intervention integrating mindfulness and positive psychology to target a dysregulated stress response in SSD. The current study is a preliminary randomized-controlled trial (RCT) comparing I-CAT (n = 18) with treatment as usual (TAU; n = 18) in individuals in the early stages of SSD. I-CAT was hypothesized to be more effective than TAU on primary outcomes: increasing positive emotions, decreasing negative emotions, reducing stress, and improving functioning and quality of life; and secondary outcomes: reducing symptoms, increasing mindfulness, and improving overall well-being. Excellent therapy attendance rates, low study attrition, and positive participant feedback demonstrated that I-CAT was a feasible and well-tolerated psychosocial intervention. Results suggest I-CAT led to greater reduction in symptoms (i.e., overall, negative, and disorganized symptoms), increased observational mindfulness, increased endorsement of a sense of purpose in life, and preservation of work abilities and school social functioning compared with TAU. Future work should replicate and extend these findings in a larger-scale RCT.

description: Tobacco origin identification is significantly important in tobacco industry. Modeling analysis for sensor data with near infrared spectroscopy has become a popular method for rapid detection of internal features. However, for sensor data analysis using traditional artificial neural network or deep network models, the training process is extremely time-consuming. In this paper, a novel broad learning system with Takagi-Sugeno (TS) fuzzy subsystem is proposed for rapid identification of tobacco origin. Incremental learning is employed in the proposed method, which obtains the weight matrix of the network after a very small amount of computation, resulting in much shorter training time for the model, with only about 3 seconds for the extra step training. The experimental results show that the TS fuzzy subsystem can extract features from the near infrared data and effectively improve the recognition performance. The proposed method can achieve the highest prediction accuracy (95.59 %) in comparison to the traditional classification algorithms, artificial neural network, and deep convolutional neural network, and has a great advantage in the training time with only about 128 seconds.
Buoyancy and Marangoni Effects on Horizontal Ribbon Growth

description: Unsteady simulations of horizontal ribbon growth of silicon were performed that included both Marangoni and buoyancy effects. A chaotic flow was observed dominated by strong Marangoni-driven jets emerging near the local temperature minima on the free surface. This oscillatory flow caused the vertical position of the leading edge of the sheet to fluctuate, resulting in corrugations on the top surface of the ribbon. Additionally, larger amplitude and wavelength nonuniformities appeared on the bottom of the sheet resulting in a sheet with varying thickness. Lastly, the unsteady flow caused temporal variations in growth rate, which when converted to distance using the pull speed, matched the wavelengths observed on the top surface. All three of these phenomena have been observed experimentally: The median of the surface wavelengths and amplitudes decreased with increasing temperature sensitivity of surface tension and had wavelengths on the same order as experiments for a sensitivity corresponding to uncontaminated silicon. Oscillations in growth rate have been observed using passive antimony demarcation and thickness variations have been measured after sheet removal. These results indicate that the chaotic flow makes producing thin uniform sheets using HRG challenging.

description: With the tremendous advancements in technology and the Internet, data security has become a major issue around the globe. To guarantee that data is protected and does not go to an unintended endpoint, the art of data hiding (steganography) emerged. Steganography is the art of hiding information such that it is not detectable to the naked eye. Various techniques have been proposed for hiding a secret message in a carrier document. In this paper, we present a novel design that applies Reed-Solomon (RS) error correcting codes in steganographic applications. The model works by substituting the redundant RS codes with the steganographic message. The experimental results show that the proposed design is satisfactory with the percentage of decoded information 100% and percentage of decoded secret message 97. 36%. The proposed model proved that it could be applied in various steganographic applications.

description: My comments on "A Proposal for Redefining the Monetary Aggregates,11 (Federal Reserve Bulletin January 1978) takes the form of three separate statements. One is the statement adopted by the Shadow Open Market Committee on March 11. The second is a criticism of the computation of the monetary base as currently defined and published in Washington* The criticism is excerpted from a weekly letter written by H. Erich Heinemann, a Vice President of Morgan Stanley and Company. The third was written by Jerry L. Jordan, former director of research at the Federal Reserve Bank of St. Louis and currently a Senior Vice-President at Pittsburgh National Bank. I have included the statements by Heinemann and Jordan not only because I regard them as correct, but because they present the positions of two knowledgeable users of monetary data.

description: The field of artificial intelligence based image enhancement has been rapidly evolving over the last few years and is able to produce impressive results on non-astronomical images. In this work we present the first application of Machine Learning based super-resolution (SR) and de-noising (DN) to enhance X-ray images from the European Space Agency's XMM-Newton telescope. Using XMM-Newton images in band [0.5, 2] keV from the European Photon Imaging Camera pn detector (EPIC-pn), we develop XMM-SuperRes and XMM-DeNoise deep learning-based models that can generate enhanced SR and DN images from real observations. The models are trained on realistic XMM-Newton simulations such that XMM-SuperRes will output images with two times smaller point-spread function and with improved noise characteristics. The XMM-DeNoise model is trained to produce images with 2.5x the input exposure time from 20 to 50 ks. When tested on real images, DN improves the image quality by 8.2%, as quantified by the global peak-signal-to-noise ratio. These enhanced images allow identification of features that are otherwise hard or impossible to perceive in the original or in filtered/smoothed images with traditional methods. We demonstrate the feasibility of using our deep learning models to enhance XMM-Newton X-ray images to increase their scientific value in a way that could benefit the legacy of the XMM-Newton archive.

description: We review theoretical foundations and some recent progress related to the quest of controlling the motion of charge carriers with intense laser pulses and optical waveforms. The tools and techniques of attosecond science enable detailed investigations of a relatively unexplored regime of nondestructive strong-field effects. Such extremely nonlinear effects may be utilized to steer electron motion with precisely controlled optical fields and switch electric currents at a rate that is far beyond the capabilities of conventional electronics.

description: The $\boldsymbol{p}$-adic diaphony as introduced by Hellekalek is a quantitative measure for the irregularity of distribution of a sequence in the unit cube. In this paper we show how this notion of diaphony can be interpreted as worst-case integration error in a certain reproducing kernel Hilbert space. Our main result is an upper bound on the $\boldsymbol{p}$-adic diaphony of the Halton sequence.
Parameter-free analytic continuation for quantum many-body calculations

description: We develop a reliable parameter-free analytic continuation method for quantum many-body calculations. Our method is based on a kernel grid, a causal spline, a regularization using the second-derivative roughness penalty, and the L-curve criterion. We also develop the L-curve averaged deviation to estimate the precision of our analytic continuation. To deal with statistically obtained data more efficiently, we further develop a bootstrap-averaged analytic continuation method. In the test using the exact imaginary-frequency Green's function with added statistical error, our method produces the spectral function that converges systematically to the exact one as the statistical error decreases. As an application, we simulate the two-orbital Hubbard model for various electron numbers with the dynamical-mean field theory in the imaginary time and obtain the real-frequency self-energy with our analytic continuation method, clearly identifying a non-Fermi liquid behavior as the electron number approaches the half filling from the quarter filling. Our analytic continuation can be used widely and it will facilitate drawing clear conclusions from imaginary-time quantum many-body calculations.

A theory for the stabilization of polar crystal surfaces by a liquid environment

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Polar crystal surfaces play an important role in the functionality of many materials, and have been studied extensively over many decades. In this article, a theoretical framework is presented that extends existing theories by placing the surrounding solution environment on an equal footing with the crystal itself; this is advantageous, e.g., when considering processes such as crystal growth from solution. By considering the polar crystal as a stack of parallel plate capacitors immersed in a solution environment, the equilibrium adsorbed surface charge density is derived by minimizing the free energy of the system. In analogy to the well-known diverging surface energy of a polar crystal surface at zero temperature, for a crystal in solution it is shown that the "polar catastrophe" manifests as a diverging free energy cost to perturb the system from equilibrium. Going further than existing theories, the present formulation predicts that fluctuations in the adsorbed surface charge density become increasingly suppressed with increasing crystal thickness. We also show how, in the slab geometry often employed in both theoretical and computational studies of interfaces, an electric displacement field emerges as an electrostatic boundary condition, the origins of which are rooted in the slab geometry itself, rather than the use of periodic boundary conditions. This aspect of the work provides a firmer theoretical basis for the recent observation that standard "slab corrections" fail to correctly describe, even qualitatively, polar crystal surfaces in solution.

description: Since its inception, the Scanlon Plan has attracted considerable attention. The current national concern with productivity has renewed interest in the Plan as a way to improve productivity levels as well as the quality of work. The attractive features of the Plan include a phi1osopy based on cooperative labor-management relationships, a structure for increasing productivity, and an opportunity for increased need satisfaction for all employees. Despite the many benefits attributed to the Plan, it is the position of this paper that: (1) there have been few well designed studies that can assess the multiple impacts of the Plan, and (2) there has been little theoretical elaboration of models that would aid in predicting , the impact of the Plan in different types of organizations over time. The lack of systematic research and theorizing is not mer'e1y of academic interest; it also has real practical implications.

description: The open-source python package diffpy.mpdf, part of the DiffPy suite for diffraction and pair distribution function analysis, provides a user-friendly approach for performing magnetic pair distribution function (mPDF) analysis. The package builds on existing libraries in the DiffPy suite to allow users to create models of magnetic structures and calculate corresponding one-dimensional and three-dimensional mPDF patterns. diffpy.mpdf can be used to perform fits to mPDF data either in isolation or in combination with atomic PDF data for joint refinements of the atomic and magnetic structure. Examples are given using MnO and MnTe as representative antiferromagnetic compounds and MnSb as a representative ferromagnet.

description: Purpose: Psychotic disorders develop during mid-adolescence through early adulthood, with the initial few months a “critical period” offering the greatest promise for recovery. However, the duration of untreated psychosis is typically over a year. This study aimed to identify aspects of care episodes contributing to delays in diagnosis of a first psychotic episode. Methods: Study subjects included 161 adolescents and young adults referred to a first episode psychosis treatment program. We captured the various ways that people who experience a severe mental illness engage in treatment using standardized interviews with patients and informants (e.g., family member) and medical record review. Results: A psychotic disorder diagnosis was not given for 38% of subjects at their initial episode of care. Time to first care episode was virtually the same for subjects that did and did not receive a psychosis diagnosis; 50% within 1 month and 84% within 6 months. Compared to initial care episodes with a psychosis diagnosis, those without a psychosis diagnosis less often involved emergency services (80% vs. 38%, respectively; p value = 1 × 10−7) and more often outpatient primary care (6% vs. 18%; p value = .032) and mental health (32% vs. 49%; p value = .045) services. However, dangerousness indicators were similar (29% vs. 28%; p value = 1). Dangerousness indicators increased to 54% (p value = .002) by the time of eventual diagnosis for those requiring multiple care episodes. Conclusions: Clinicians were important contributors to delays in diagnosis and treatment of psychosis. Interventions targeting outpatient health care providers may be fruitful in reducing the duration of untreated psychosis.

description: We report the first example of magnetic pair distribution function (mPDF) data obtained through use of neutron polarization analysis. Using the antiferromagnetic semiconductor MnTe as a test case, we present high-quality mPDF data collected on the HYSPEC instrument at the Spallation Neutron Source using longitudinal polarization analysis to isolate the magnetic scattering cross section. Clean mPDF patterns are obtained for MnTe in both the magnetically ordered state and the correlated paramagnet state, where only short-range magnetic order is present. We also demonstrate significant improvement in the quality of high-resolution mPDF data through application of ad hoc corrections that require only minimal human input, minimizing potential sources of error in the data processing procedure. We briefly discuss the current limitations and future outlook of mPDF analysis using polarized neutrons. Overall, this work provides a useful benchmark for mPDF analysis using polarized neutrons and provides an encouraging picture of the potential for routine collection of high-quality mPDF data.

description: We envision that quantum spin Hall effect should be observed in $(111)$-oriented thin films of SnSe and SnTe topological crystalline insulators. Using a tight-binding approach supported by first-principles calculations of the band structures we demonstrate that in these films the energy gaps in the two-dimensional band spectrum depend in an oscillatory fashion on the layer thickness. These results as well as the calculated topological invariant indexes and edge state spin polarizations show that for films ~20-40 monolayers thick a two-dimensional topological insulator phase appears. In this range of thicknesses in both, SnSe and SnTe, (111)-oriented films edge states with Dirac cones with opposite spin polarization in their two branches are obtained. While in the SnTe layers a single Dirac cone appears at the projection of the G point of the two-dimensional Brillouin zone, in the SnSe (111)-oriented layers three Dirac cones at M points projections are predicted.
