description: We present results from a comprehensive lensing analysis in HST data, of the complete CLASH cluster sample. We identify new multiple-images previously undiscovered allowing improved or first constraints on the cluster inner mass distributions and profiles. We combine these strong-lensing constraints with weak-lensing shape measurements within the HST FOV to jointly constrain the mass distributions. The analysis is performed in two different common parameterizations (one adopts light-traces-mass for both galaxies and dark matter while the other adopts an analytical, elliptical NFW form for the dark matter), to provide a better assessment of the underlying systematics - which is most important for deep, cluster-lensing surveys, especially when studying magnified high-redshift objects. We find that the typical (median), relative systematic differences throughout the central FOV are $\sim40\%$ in the (dimensionless) mass density, $κ$, and $\sim20\%$ in the magnification, $μ$. We show maps of these differences for each cluster, as well as the mass distributions, critical curves, and 2D integrated mass profiles. For the Einstein radii ($z_{s}=2$) we find that all typically agree within $10\%$ between the two models, and Einstein masses agree, typically, within $\sim15\%$. At larger radii, the total projected, 2D integrated mass profiles of the two models, within $r\sim2\arcmin$, differ by $\sim30\%$. Stacking the surface-density profiles of the sample from the two methods together, we obtain an average slope of $d\log (Σ)/d\log(r)\sim-0.64\pm0.1$, in the radial range [5,350] kpc. Lastly, we also characterize the behavior of the average magnification, surface density, and shear differences between the two models, as a function of both the radius from the center, and the best-fit values of these quantities.

description: We investigate the characteristic effects of nuclear motion on attosecond transient absorption spectra in molecules by calculating the spectrum for different model systems. Two models of the hydrogen molecular ion are considered: one where the internuclear separation is fixed, and one where the nuclei are free to vibrate. The spectra for the fixed nuclei model are similar to atomic spectra reported elsewhere, while the spectra obtained in the model including nuclear motion are very different and dominated by extremely broad absorption features. These broad absorption features are analyzed and their relation to molecular dissociation investigated. The study of the hydrogen molecular ion validates an approach based on the Born-Oppenheimer approximation and a finite electronic basis. This latter approach is then used to study the three-dimensional hydrogen molecule including nuclear vibration. The spectrum obtained from H$_2$ is compared to the result of a fixed-nuclei calculation. In the attosecond transient absorption spectra of H$_2$ including nuclear motion we find a rich absorption structure corresponding to population of different vibrational states in the molecule, while the fixed-nuclei spectra again are very similar to atomic spectra. We find that light-induced structures at well-defined energies reported in atomic systems are also present in our fixed nuclei molecular spectra, but suppressed in the ${\text{H}_2}^+$ and H$_2$ spectra with moving nuclei. We show that the signatures of light-induced structures are closely related to the nuclear dynamics of the system through the shapes and relative arrangement of the Born-Oppenheimer potential energy curves.

description: We present a novel approach to generate Bessel-Gauss modes of arbitrary integer order and well-defined optical angular momentum in a gradient index medium of transverse parabolic profile. The propagation and coherence properties, as well as the quality factor, are studied using algebraic techniques that are widely used in quantum mechanics. It is found that imposing the well-defined optical angular momentum condition, the Lie group $SU(1,1)$ comes to light as a characteristic symmetry of the Bessel-Gauss beams.

description: Основными частицами, входящими в состав первичных солнечных космических лучей (СКЛ), являются протоны, их доля составляет до 90 %. Оставшаяся часть состоит из электронов и ядер с зарядовым числом Z ≥ 2. Взаимодействуя с веществом атмосферы Земли, эти частицы испытывают серии взаимодействий (в основном, с ядрами азота и кислорода), теряя свою энергию как на электромагнитные потери, так и на ядерные реакции, в ходе которых рождаются целые каскады вторичных частиц (электроны, протоны, нейтроны, каоны, мюоны, гамма-кванты). Современные подход к исследованию частиц вторичных КЛ в атмосфере Земли включает в себя как экспериментальные методы, так и численное моделирование. В ПГИ был разработан специальный модуль программного комплекса RUSCOSMICS, позволяющий детально изучать характеристики каскадов КЛ и получать их в виде количественных значений энергетических спектров, высотных кривых, а также вклада в скорость ионообразования. В данной работе представлены результаты для частного случая, когда в качестве входных значений модели используются спектры СКЛ, соответствующие событию GLENo61. Наряду с этим представлены аналогичные данные, полученные в результате прохождения через атмосферу Земли ядер кислорода первичных галактических КЛ.

description: Explainable AI (XAI) is the study on how humans can be able to understand the cause of a model's prediction. In this work, the problem of interest is Scene Text Recognition (STR) Explainability, using XAI to understand the cause of an STR model's prediction. Recent XAI literatures on STR only provide a simple analysis and do not fully explore other XAI methods. In this study, we specifically work on data explainability frameworks, called attribution-based methods, that explain the important parts of an input data in deep learning models. However, integrating them into STR produces inconsistent and ineffective explanations, because they only explain the model in the global context. To solve this problem, we propose a new method, STRExp, to take into consideration the local explanations, i.e. the individual character prediction explanations. This is then benchmarked across different attribution-based methods on different STR datasets and evaluated across different STR models.

description: A simple model is developed to describe the intermolecular interactions in solid C60. The model correctly predicts the observed ground-state structure Pa and the first-order transition to the high-temperature fcc phase. The calculated transition temperature Tc 270 K and its pressure dependence dTc/dP=11.5 K/kbar agree very well with recent experiments. Below Tc, there exist nearly degenerate orientations that are separated by potential barriers of order 300 meV, leading to a glassy behavior with T 90 130 K. It is suggested that similar orientational disorder exists in K3C60 and other fullerides.

description: The PCI diagnostic is an internal reference interferometer that creates an image of absolutely calibrated electron density fluctuations integrated along the line of sight of the probing light beam. While conventional PCI diagnostics installed on fusion experiments worldwide employ light of wavelength equal to 10.59 $μ$~m, the same system using light at 1.55 $μ$~m wavelength would extend the spectral response in wave-number and frequency by factors of seven and over one hundred, respectively, thereby potentially providing quantitative measurements of the internal structure of density perturbations induced by either turbulent or radio-frequency waves, simultaneously covering ion to electron gyro-radius scales up to the GHz frequency region. Based on a previously developed 1.55 $μ$~m PCI prototype system, constraints to the design for such a diagnostic in fusion grade devices are presented and compared to those faced with the conventional method.

description: A light injection system using LEDs and optical fibres was designed for the calibration and monitoring of the photomultiplier array of the SNO+ experiment at SNOLAB. Large volume, non-segmented, low-background detectors for rare event physics, such as the multi-purpose SNO+ experiment, need a calibration system that allow an accurate and regular measurement of the performance parameters of their photomultiplier arrays, while minimising the risk of radioactivity ingress. The design implemented for SNO+ uses a set of optical fibres to inject light pulses from external LEDs into the detector. The design, fabrication and installation of this light injection system, as well as the first commissioning tests, are described in this paper. Monte Carlo simulations were compared with the commissioning test results, confirming that the system meets the performance requirements.

description: Orientational disorder appears to persist in solid C60 even at low temperature, and similar static disorders is likely to exist in A3C60. The effects of such disorder on their electronic structures are studied by three-band tight-binding models for the C60 and A3C60 conduction bands. The densities of states for the disordered systems are quite different from those in the ordered systems. Participation-ratio analyses suggest that most of the states are delocalized, but there should nonetheless be a host of experimental consequences associated with short mean free paths.

description: This paper introduces an innovative approach to road network generation through the utilization of a multi-modal Large Language Model (LLM). Our model is specifically designed to process aerial images of road layouts and produce detailed, navigable road networks within the input images. The core innovation of our system lies in the unique training methodology employed for the large language model to generate road networks as its output. This approach draws inspiration from the BLIP-2 architecture arXiv:2301.12597, leveraging pre-trained frozen image encoders and large language models to create a versatile multi-modal LLM. Our work also offers an alternative to the reasoning segmentation method proposed in the LISA paper arXiv:2308.00692. By training the large language model with our approach, the necessity for generating binary segmentation masks, as suggested in the LISA paper arXiv:2308.00692, is effectively eliminated. Experimental results underscore the efficacy of our multi-modal LLM in providing precise and valuable navigational guidance. This research represents a significant stride in bolstering autonomous navigation systems, especially in road network scenarios, where accurate guidance is of paramount importance.

description: The human habitat is a host where microbial species evolve, function, and continue to evolve. Elucidating how microbial communities respond to human habitats is a fundamental and critical task, as establishing baselines of human microbiome is essential in understanding its role in human disease and health. However, current studies usually overlook a complex and interconnected landscape of human microbiome and limit the ability in particular body habitats with learning models of specific criterion. Therefore, these methods could not capture the real-world underlying microbial patterns effectively. To obtain a comprehensive view, we propose a novel ensemble clustering framework to mine the structure of microbial community pattern on large-scale metagenomic data. Particularly, we first build a microbial similarity network via integrating 1920 metagenomic samples from three body habitats of healthy adults. Then a novel symmetric Nonnegative Matrix Factorization (NMF) based ensemble model is proposed and applied onto the network to detect clustering pattern. Extensive experiments are conducted to evaluate the effectiveness of our model on deriving microbial community with respect to body habitat and host gender. From clustering results, we observed that body habitat exhibits a strong bound but non-unique microbial structural patterns. Meanwhile, human microbiome reveals different degree of structural variations over body habitat and host gender. In summary, our ensemble clustering framework could efficiently explore integrated clustering results to accurately identify microbial communities, and provide a comprehensive view for a set of microbial communities. Such trends depict an integrated biography of microbial communities, which offer a new insight towards uncovering pathogenic model of human microbiome.

description: We have measured the anisotropic thermal conductivity of an untwinned single crystal of YBa2Cu3O7- in the most conducting a-b plane from 14 to 200 K. Unlike previous analyses, ours attributes the observed rapid rise in thermal conductivity in the superconducting state to the electronic contribution of the Cu-O plane. We propose that strong suppression of the quasiparticle scattering rate with decreasing temperature is responsible for the large enhancement of the superconducting-state thermal conductivity.
The Connection Between the Positron Fraction Anomaly and the Spectral Features in Galactic Cosmic-Ray Hadrons

description: Recent data on Galactic cosmic-ray (CR) leptons and hadrons gave rise to two exciting problems: on the lepton side, the origin of the rise of the CR positron fraction e+/(e- + e+) at ~10 - 300 GeV of energy; on the hadron side, the nature of the spectral hardening observed in CR protons and nuclei at ~TeV energies. The lepton anomaly indicates the existence of a nearby e+/- source. It has been proposed that high-energy positrons can be produced inside nearby supernova remnants (SNRs) via interactions of CR hadrons with the ambient medium. A distinctive prediction of this mechanism is a high-energy rise of the boron-to-carbon ratio, which has not been observed. It also requires old SNRs at work (with ineffective magnetic field amplification and slow shock speed), that cannot account for the CR hadronic spectra observed up to the knee energies (~5 PeV). We propose a new picture where, in addition to such a nearby CR accelerator, the high-energy spectrum of CR hadrons is provided by the large-scale population of SNRs, on average younger, that can efficiently accelerate CRs up to the knee. Under this scenario, the spectral hardening of CR hadrons can be naturally interpreted as the transition between the two components. As we will show, our two-component model breaks the connection between the positron fraction and the boron-to-carbon ratio, which is now predicted to decrease with energy in accordance with the data. Forthcoming data from AMS will be crucial for testing this model.

description: Recently, SyncMap pioneered an approach to learn complex structures from sequences as well as adapt to any changes in underlying structures. This is achieved by using only nonlinear dynamical equations inspired by neuron group behaviors, i.e., without loss functions. Here we propose Symmetrical SyncMap that goes beyond the original work to show how to create dynamical equations and attractor-repeller points which are stable over the long run, even dealing with imbalanced continual general chunking problems (CGCPs). The main idea is to apply equal updates from negative and positive feedback loops by symmetrical activation. We then introduce the concept of memory window to allow for more positive updates. Our algorithm surpasses or ties other unsupervised state-of-the-art baselines in all 12 imbalanced CGCPs with various difficulties, including dynamically changing ones. To verify its performance in real-world scenarios, we conduct experiments on several well-studied structure learning problems. The proposed method surpasses substantially other methods in 3 out of 4 scenarios, suggesting that symmetrical activation plays a critical role in uncovering topological structures and even hierarchies encoded in temporal data.

description: We investigate the star formation activity in a young star forming cluster embedded at the edge of the RCW 41 HII region. As a complementary goal, we aim at demonstrating the gain provided by Wide-Field Adaptive Optics instruments to study young clusters. We used deep, JHKs images from the newly commissioned Gemini-GeMS/GSAOI instrument, complemented with Spitzer IRAC observations, in order to study the photometric properties of the young stellar cluster. GeMS is an AO instrument, delivering almost diffraction limited images over a field of 2' across. The exquisite angular resolution allows us to reach a limiting magnitude of J = 22 for 98% completeness. The combination of the IRAC photometry with our JHKs catalog is used to build color-color diagrams, and select Young Stellar Objects (YSOs) candidates. We detect the presence of 80 Young Stellar Object (YSO) candidates. Those YSOs are used to infer the cluster age, which is found to be in the range 1 to 5 Myr. We find that 1/3 of the YSOs are in a range between 3 to 5 Myr, while 2/3 of the YSO are < 3 Myr. When looking at the spatial distribution of these two populations, we evidence a potential age gradient across the field, suggesting sequential star formation. We construct the IMF, and show that we can sample the mass distribution well into the brown dwarf regime (down to 0.01 Msun). The logarithmic mass function rises to peak at 0.3 Msun, before turning over and declining into the brown dwarf regime. The total cluster mass derived is estimated to be 78 +/- 18 Msun, while the ratio of brown dwarfs to star derived is 18 p/- 5 %. When comparing with other young clusters, we find that the IMF shape of the young cluster embedded within RCW 41 is consistent with those of Trapezium, IC 348 or Chamaeleon I, except for the IMF peak, which happens to be at higher mass. This characteristic is also seen in clusters like NGC 6611 or even Taurus.

description: Background: Von Willebrand Factor (VWF) antigen is released from activated endothelial cells and platelets. It plays a role in vascular inflammation and thrombosis, both important in the pathogenesis of Antineutrophil Cytoplasmic Antibody-associated vasculitis (AAV). Previous work found that VWF correlates with disease activity in childhood-onset primary CNS vasculitis1. We sought to determine the relationship between VWF and disease activity over time in children with AAV. Methods: This is a retrospective cohort study including children diagnosed with granulomatosis with polyangiitis and microscopic polyangiitis according to European league against rheumatism (EULAR)/ Paediatric Rheumatology International Trials Organisation (PRINTO)/ Paediatric Rheumatology European Society (PReS) classification criteria for childhood vasculitis or the Chapel Hill Consensus Conference (CHCC) disease definitions at The Hospital for Sick Children, Toronto, between 2006 and 2019. The primary outcome measure was active disease attributable to vasculitis. How this related to laboratory parameters including platelets, c-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and serial VWF antigen measurements was studied using generalized estimating equations (GEE) analysis to account for repeated measurements within a patient. Repeated measures correlation was used to determine associations of paired observations within a child. Diagnostic performance was evaluated using receiver operating curve (ROC) analysis. Results: 731 total VWF measurements were collected in 25 GPA and 8 MPA patients. Baseline demographics and disease characteristics are shown in Table 1. VWF antigen levels were higher during active disease (median = 2.03 IU/mL, IQR = [1.35, 2.55]) compared to inactive disease (median = 1.18 IU/mL, IQR = [0.94, 1.53). VWF antigen was the only variable that is significantly associated with active disease (OR 3.01, p<0.001, 95CI [2.3, 3.93]). The effect of VWF did not show a substantial difference between the MPA versus GPA. There was a moderate positive correlation between VWF antigen and WBC, and moderate negative correlation with HGB and GFR. The AUC was 0.87 with all (VWF, ESR, CRP, platelets) laboratory parameters included, 0.86 and 0.81 when platelets and VWF were removed, respectively. Conclusions: Increased VWF antigen levels correlate with active vasculitis in this pediatric-onset AAV cohort, and this may be used as an additional biomarker in childhood ANCA-associated vasculitis.

description: The results of a semiclassical variational calculation of the t-J model are presented. The generalized staggered flux phases are introduced. It is found that these flux phases are stable for a large parameter range of the phase diagram. An interesting feature of these flux phases is that for small doping they have the best potential energy and for larger doping they have the best kinetic energy. It is also found that only those flux phases that do not break the local time reversal and parity symmetries are energetically favored. For sufficiently small J/t and doping the spiral phase is stable.

description: The production of long-lived radioactive isotopes in materials due to the exposure to cosmic rays on Earth surface can be an hazard for experiments demanding ultra-low background conditions, typically performed deep underground. Production rates of cosmogenic isotopes in all the materials present in the experimental set-up, as well as the corresponding cosmic rays exposure history, must be both well known in order to assess the relevance of this effect in the achievable sensitivity of a given experiment. Although NaI(Tl) scintillators are being used in experiments aiming at the direct detection of dark matter since the first nineties of the last century, very few data about cosmogenic isotopes production rates have been published up to date. In this work we present data from two 12.5 kg NaI(Tl) detectors, developed in the frame of the ANAIS project, which were installed inside a convenient shielding at the Canfranc Underground Laboratory just after finishing surface exposure to cosmic rays. The very fast start of data taking allowed to identify and quantify isotopes with half-lives of the order of tens of days. Initial activities underground have been measured and then production rates at sea level have been estimated following the history of detectors; values of about a few tens of nuclei per kg and day for Te isotopes and 22Na and of a few hundreds for I isotopes have been found. These are the first direct estimates of production rates of cosmogenic nuclides in NaI crystals. A comparison of the so deduced rates with calculations using typical cosmic neutron flux at sea level and a carefully selected description of excitation functions will be also presented together with an estimate of the corresponding contribution to the background at low and high energies, which can be relevant for experiments aiming at rare events searches.

description: Вторгаясь в атмосферу Земли, космические лучи (КЛ) испытывают множество взаимодействий с окружающим их веществом, теряя при этом свою энергию. Одним из важных для исследования процессов является ионизация, которая индуцируется этими частицами в большом диапазоне высот, начиная примерно от 80 км и вплоть до уровня земли. При этом, в зависимости от их начальной энергии меняется, соответственно, и скорость ионообразования. В представленной работе рассматривается моделирование прохождения протонов галактических КЛ (ГКЛ) в случае использования глобальной геометрии атмосферы, построенной на базе NRLMSISE-00, при этом шаг сетки для выбора физических параметров (температура, плотность, состав) составляет 5 градусов. Спектр первичных частиц соответствует минимуму солнечной активности, а значения жесткости геомагнитного обрезания получены посредством модели IGRF. Результатом вычислений является карта ионизации атмосферы Земли для интервала широты от -90 до 90 градусов, долготы от 0 до 360 градусов и высоты от 0 до 80 км. Также производится верификация модельных данных при помощи высотных профилей скорости счета, полученных в ходе эксперимента по запуску шаров-зондов с установленными на них счетчиками Гейгера.

description: Although most pregnancies result in a good outcome, complications are not uncommon and can be associated with serious implications for mothers and babies. Predictive modeling has the potential to improve outcomes through better understanding of risk factors, heightened surveillance for high risk patients, and more timely and appropriate interventions, thereby helping obstetricians deliver better care. We identify and study the most important risk factors for four types of pregnancy complications: (i) severe maternal morbidity, (ii) shoulder dystocia, (iii) preterm preeclampsia, and (iv) antepartum stillbirth. We use an Explainable Boosting Machine (EBM), a high-accuracy glass-box learning method, for prediction and identification of important risk factors. We undertake external validation and perform an extensive robustness analysis of the EBM models. EBMs match the accuracy of other black-box ML methods such as deep neural networks and random forests, and outperform logistic regression, while being more interpretable. EBMs prove to be robust. The interpretability of the EBM models reveals surprising insights into the features contributing to risk (e.g. maternal height is the second most important feature for shoulder dystocia) and may have potential for clinical application in the prediction and prevention of serious complications in pregnancy.

description: Berry curvature is a fundamental element to characterize topological quantum physics, while a full measurement of Berry curvature in momentum space was not reported for topological states. Here we achieve two-dimensional Berry curvature reconstruction in a photonic quantum anomalous Hall system via Hall transport measurement of a momentum-resolved wave packet. Integrating measured Berry curvature over the two-dimensional Brillouin zone, we obtain Chern numbers corresponding to -1 and 0. Further, we identify bulk-boundary correspondence by measuring topology-linked chiral edge states at the boundary. The full topological characterization of photonic Chern bands from Berry curvature, Chern number, and edge transport measurements enables our photonic system to serve as a versatile platform for further in-depth study of novel topological physics.

description: Результатом моделирования прохождения протонов первичных космически лучей (КЛ) через атмосферу Земли при помощи программного комплекса RUSCOSMICSявляется количественная оценка значений потоков частицвторичных КЛ на разных высотах (до 80 км). Для обеспечения высокого уровня соответствия реальным условиям, эти данные должны проходить обязательную верификацию. Наилучшим методом является их сравнение с высотными профилями скорости счета, полученными в ходе экспериментов по запуску стратосферных шаров-зондов с установленными на них счетчиками Гейгера. Несмотря на то, что проверка корректности происходит для локального участка, такой подход можно назвать преимущественным, поскольку полеты проводятся на протяжении нескольких десятков лет и обеспечивают хорошую точность имеющимся рядам данных. В представленной работе рассматривается верификация результатов моделирования, полученных для случая минимума солнечной активности.
Pairing of spinless fermions in two dimensions

Year: 1991

description: We study the real-space pairing instability of spinless fermions on a two-dimensional square lattice with short-range attractive interactions. Various symmetries of the pairing order parameter are considered. It is found that in both nonflux and flux phases the most stable pairing state is chiral and anisotropic. It breaks both the parity and the time-reversal symmetries. The quasiparticle excitation has a minimum gap which could be much smaller than its average over the Fermi surface. The temperature dependence of the order parameter and the critical magnetic field are found to be similar to those of the classical BCS solutions. A possible connection with the high-temperature superconductivity is discussed.

description: At a distance of 50 kpc and with a dark matter mass of $\sim10^{10}$ M$_{\odot}$, the Large Magellanic Cloud (LMC) is a natural target for indirect dark matter searches. We use five years of data from the Fermi Large Area Telescope (LAT) and updated models of the gamma-ray emission from standard astrophysical components to search for a dark matter annihilation signal from the LMC. We perform a rotation curve analysis to determine the dark matter distribution, setting a robust minimum on the amount of dark matter in the LMC, which we use to set conservative bounds on the annihilation cross section. The LMC emission is generally very well described by the standard astrophysical sources, with at most a $1-2σ$ excess identified near the kinematic center of the LMC once systematic uncertainties are taken into account. We place competitive bounds on the dark matter annihilation cross section as a function of dark matter particle mass and annihilation channel.

description: For quiet geomagnetic conditions during solar terminator passages results of observations of amplitude variations of the partial reflection radar signals (the observatory Tumanny of the Polar Geophysical Institute, 69.0N, 35.7E) at the heights of the D-region of the ionosphere are given. Temporary variations of signal amplitudes which were reflected at the height of 75 km and their spectra were analyzed. It was found that the components of the time spectrum of the variations which correspond to resonant frequencies of the atmosphere (the acoustic cut-off and the Brunt-Väisälä ones) in certain cases were intensified. On the basis of the theory of acoustic-gravity waves and the empirical model of neutral structure and temperature of the atmosphere NRLMSISE-00identification of the experimental periods corresponding to the atmospheric resonances has been done and calculation of neutral temperature at the heights of the mesosphere have been carried out. The values of the calculated temperature from experimental data showed satisfactory consent with data of other independent observations.

description: In the Higgs portal framework, the Higgs field generally mixes with the Standard Model singlet leading to the existence of two states, one of which is identified with the 125 GeV scalar observed at the LHC. In this work, we analyse direct and indirect constraints on the second mass eigenstate and the corresponding mixing angle. The existence of the additional scalar can be beneficial as it can stabilise the otherwise-metastable electroweak vacuum. We find parameter regions where all of the bounds, including the stability constraints, are satisfied. We also study prospects for observing the decay of the heavier state into a pair of the 125 GeV Higgs-like scalars.

description: This paper examines the problem of stabilizing linear distributed delay systems with nonlinear distributed delay kernels and dissipativity constraints. Specifically, the nonlinear distributed kernel includes functions such as polynomials, trigonometric and exponential functions. By constructing a Liapunov-Krasovskiǐ functional related to the distributed kernels, sufficient conditions for the existence of a state feedback controller which stabilizes the uncertain distributed delay systems with dissipativity constraints are given in terms of linear matrix inequalities (LMIs). In contrast to existing methods, the proposed scenario is less conservative or requires a smaller number of decision variables based on the application of a newly derived integral inequality. Finally, numerical examples are presented to demonstrate the validity and effectiveness of the proposed methodology.

description: The precipitations of energetic electrons observed at the Spitsbergen latitude, which manifest themselves in the optical range as auroras, differ in their origin and morphology from the precipitations in other regions of the auroral zone. The electron energy determines the height of the auroral luminescence, which in the experiment can be determined from triangulation observations. In 2018, optical devices of the Polar Geophysical Institute on the Spitsbergen archipelago were supplemented with an additionalcamera. The camera is installed in the Barentsburg settlement, 4 km southern of the main optical pavilion and has a field of view of about 30 degrees. In patrol mode, the camera is directed to the zenith, which allows, together with the data of the all-sky camera, located in the main optical pavilion, to obtain information about the height of the observed structures of auroras in the vicinity of the zenith. The report contains the parameters of the optical system used for triangulation and examples of the registration of auroral structures.
Spin polarons in high-Tc copper oxides: Differences between electron- and hole-doped systems
Creators: name: Si, Q.
name: Lu, J.P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: It is argued that in the small-doping region there is an asymmetry between the hole-doped and the electron-doped copper oxide systems. This asymmetry is reflected in both the magnetic and transport properties. Significant oxygen p-p orbital overlap leads to a large conduction-band width, which has qualitatively different effects on the two differently doped systems. In the hole-doped case, large-spin polarons are formed as the system is doped; this leads to a quick destruction of the antiferromagnetic correlation. In the electron-doped case, doped carriers are more localized; thus the magnetic correlation is more robust with respect to doping. In the low doping concentration, the low-temperature conductivity is shown to be two-dimensional variable-range-hopping type. The conductivity, which is expected to scale with the asymmetry of the magnetic phase diagram, is smaller in an electron-doped system than that of a hole-doped system.
