description: An approach to optimizing the Q factors of two-dimensional photonic crystal (2D-PC) nanocavities based on deep learning is proposed and demonstrated. We prepare a dataset consisting of 1000 nanocavities generated by randomly displacing the positions of many air holes of a base nanocavity and their Q factors calculated by a first-principle method. We train a four-layer neural network including a convolutional layer to recognize the relationship between the air holes' displacements and the Q factors using the prepared dataset. After the training, the neural network becomes able to estimate the Q factors from the air holes' displacements with an error of 13% in standard deviation. Crucially, the trained neural network can estimate the gradient of the Q factor with respect to the air holes' displacements very quickly based on back-propagation. A nanocavity structure with an extremely high Q factor of 1.58 x 10^9 is successfully obtained by optimizing the positions of 50 air holes over ~10^6 iterations, having taken advantage of the very fast evaluation of the gradient in high-dimensional parameter space. The obtained Q factor is more than one order of magnitude higher than that of the base cavity and more than twice that of the highest Q factors reported so far for cavities with similar modal volumes. This approach can optimize 2D-PC structures over a parameter space of a size unfeasibly large for previous optimization methods based solely on direct calculations. We believe this approach is also useful for improving other optical characteristics.

description: We consider a network model of snake states to study the localization problem of non-interacting fermions in a random magnetic field with zero average. After averaging over the randomness, the network of snake states is mapped onto $M$ coupled SU$(2N)$ spin chains in the $N \rightarrow 0$ limit. The number of snake states near the zero-field contour, $M$, is an even integer. In the large conductance limit $g = M {e^2 \over 2 π\hbar}$ ($M \gg 2$), it turns out that this system is equivalent to a particular representation of the ${\rm U}(2N) / {\rm U}(N) \times {\rm U}(N)$ sigma model ($N \rightarrow 0$) {\it without} a topological term. The beta function $β(1/M)$ of this sigma model in the $1/M$ expansion is consistent with the previously known $β(g)$ of the unitary ensemble. These results and further plausible arguments support the conclusion that all the states are localized.

description: We examine the effects that planetary encounters have on the moon systems of ejected gas giant planets. We conduct a suite of numerical simulations of planetary systems containing three Jupiter-mass planets (with the innermost planet at 3 AU) up to the point where a planet is ejected from the system. The ejected planet has an initial system of 100 test-particle moons. We determine the survival probability of moons at different distances from their host planet, measure the final distribution of orbital elements, examine the stability of resonant configurations, and characterize the properties of moons that are stripped from the planets. We find that moons are likely to survive in orbits with semi-major axes out beyond 200 planetary radii (0.1 AU in our case). The orbital inclinations and eccentricities of the surviving moons are broadly distributed and include nearly hyperbolic orbits and retrograde orbits. We find that a large fraction of moons in two-body and three-body mean-motion resonances also survive planetary ejection with the resonance intact. The moon-planet interactions, especially in the presence of mean-motion resonance, can keep the interior of the moons molten for billions of years via tidal flexing, as is seen in the moons of the gas giant planets in the solar system. Given the possibility that life may exist in the subsurface ocean of the Galilean satellite Europa, these results have implications for life on the moons of rogue planets---planets that drift through the galaxy with no host star.

description: We use the deuteration of $c$-$\mathrm{C_{3}H_{2}}$ to probe the physical parameters of starless and protostellar cores, related to their evolutionary states, and compare it to the $\mathrm{N_{2}H^{+}}$-deuteration in order to study possible differences between the deuteration of C- and N-bearing species. We observed the main species $c$-$\mathrm{C_{3}H_{2}}$, the singly and doubly deuterated species $c$-$\mathrm{C_{3}HD}$ and $c$-$\mathrm{C_{3}D_{2}}$, as well as the isotopologue $c$-$\mathrm{{H^{13}CC_{2}H}}$ toward 10 starless cores and 5 protostars in the Taurus and Perseus Complexes. We examined the correlation between the $N$($c$-$\mathrm{C_{3}HD}$)/$N$($c$-$\mathrm{C_{3}H_{2}}$) ratio and the dust temperature along with the $\mathrm{H_2}$ column density and the CO depletion factor. The resulting $N$($c$-$\mathrm{C_{3}HD}$)/$N$($c$-$\mathrm{C_{3}H_{2}}$) ratio is within the error bars consistent with $10\%$ in all starless cores with detected $c$-$\mathrm{C_{3}HD}$. This also accounts for the protostars except for the source HH211, where we measure a high deuteration level of $23\%$. The deuteration of $\mathrm{N_{2}H^{+}}$ follows the same trend but is considerably higher in the dynamically evolved core L1544. Toward the protostellar cores the coolest objects show the largest deuterium fraction in $c$-$\mathrm{C_{3}H_{2}}$. We show that the deuteration of $c$-$\mathrm{C_{3}H_{2}}$ can trace the early phases of star formation and is comparable to that of $\mathrm{N_{2}H^{+}}$. However, the largest $c$-$\mathrm{C_{3}H_{2}}$ deuteration level is found toward protostellar cores, suggesting that while $c$-$\mathrm{C_{3}H_{2}}$ is mainly frozen onto dust grains in the central regions of starless cores, active deuteration is taking place on ice.

description: Image processing problems have always been challenging due to the complexity of the signal. These problems comprise image enhancement, such as denoising, inpainting or digital zoom, decomposing the image into relevant parts, such as background subtraction
and segmentation, image compression, object identification or recognition, and others. The complexity of the signal comes from the dimension of the images and by the large number of variations that can occur, such as contrast, luminance, occlusions, perspective, scale, rotation, etc.. This variety of problems has been tackled
with different methods, with many of them depending on a transformation of the signal into a more meaningful representation. For instance, image compression
relies on the fact that images can be accurately represented by a small number of elements of a proper basis. These include the Fourier or wavelet domains, but in fact
any collection of elements can be used to efficiently represent images, as long as they constitute sources commonly found in images. This suggests that images belong to a type of signal that can be targeted by the sparse coding framework.
Sparse coding assumes that a certain class of signals can be expressed linearly by a small number of elements from a given set or frame. A range of image processing
problems can then be solved by cleverly formulating an optimization problem with three main components: an objective function that matches the criterion to optimize,
an appropriate frame or dictionary, and a penalty or constraint that enforces sparsity of the image representation. Strictly speaking, the sparsity of a vector is defined by

description: Social isolation affects a quarter of older adults in the United States, complicating efforts for Americans who wish to age at home or in the community. Social isolation is a key risk factor for adverse health outcomes and high health care costs, and is expected to have increased during COVID-19 due to social distancing efforts. However, little research has examined the impact of social isolation on health care utilization. Literature in this area tends to be conducted internationally, uses short follow-up times, measures social isolation through single-item variables, and usually does not control for both social isolation and loneliness in the same sample. No prior studies have examined the association between social isolation and nursing home entry in a United States-based sample. This dissertation includes three studies that expand knowledge on the associations between social isolation and hospitalization, nursing home entry, and mortality in a nationally-representative sample of community-dwelling Americans ages 65 and older. Data from the Health and Retirement Study were used to construct a multi-domain measure of social isolation while controlling for loneliness. The first study uses a panel data analysis to examine whether social isolation was associated with overnight hospital stays, nursing home entry, and mortality among older adults tracked between 2006 and 2018. The second study uses a time-to-event analysis to examine whether social isolation is associated with earlier time to long-term nursing home placement (residency of 100+ days) and mortality over ten years. The third study provides an exploratory, cross-sectional analysis to examine whether use of senior services moderates the association between social isolation and nursing home entry among respondents interviewed between 2010 and 2012. Results demonstrate that social isolation is significantly associated with increased nursing home entry and early mortality. Research examining the association between social isolation and health care utilization has important implications for the expansion of home and community-based services under Medicaid and billing codes to cover screening, referral, and treatment under Medicare. Future research should evaluate whether initiatives that enhance social connections in home or community-based settings are effective in offsetting nursing home entry, reducing premature mortality, and curbing health care costs for patients and payers.

description: The masses and dispersions of light hadrons are calculated in lattice QCD using an O(a^2) tadpole-improved gluon action and an O(a^2) tadpole-improved next-nearest-neighbor fermion action originally proposed by Hamber and Wu. Two lattices of constant volume with lattice spacings of approximately 0.40 fm and 0.24 fm are considered. The results reveal some scaling violations at the coarser lattice spacing on the order of 5%. At the finer lattice spacing, the calculated mass ratios reproduce state-of-the-art results using unimproved actions. Good dispersion and rotational invariance up to momenta of pa ~ 1 are also found. The relative merit of alternative choices for improvement operators is assessed through close comparisons with other plaquette-based tadpole-improved actions.

description: It is proposed that a lattice, with constituent masses and spring constants, may be considered as a model system for topological matter. For instance, a relative variation of the inter- and intra-unit cell spring constants can be used to create, tune, and invert band structure. Such an aspect is obtained while preserving time reversal symmetry, and consequently emulates the quantum spin Hall effect. The modal displacement fields of the mass-spring lattice were superposed so to yield pseudospin fields, with positive or negative group velocity. Considering that harmonic oscillators are the basis of classical and quantum excitations over a range of physical systems, the spring-mass system yields further insight into the constituents and possible utility of topological material.

description: Plunging river inflows affect lake and reservoir water quality, reservoir storage capacity and hazards. After plunging, they form gravity-driven density currents near the bed. The plunging process at the river-lake/reservoir interface provides upstream boundary conditions for density currents and controls the pathway and fate of all constituents they carry. It is therefore important to identify and quantify the turbulent flow and mixing processes diluting the plunging inflow by entraining ambient water. In the present study, for the first time, the three-dimensional flow field of a laterally unconfined plunging inflow was measured in the field using a vesselmounted ADCP at the Rhône River inflow at Lake Geneva (Switzerland/France). The ADCP data provide insight into the related hydrodynamic processes and a direct quantification of the plunging mixing coefficient Ep. The value found for Ep is an order of magnitude larger than previously observed in laterally confined configurations.

The uncertainties are around $40\%$ smaller than those from $Planck$ 2015 TT$+$lowP. In order to check the validity of these new distance priors, we adopt the distance priors to constrain the cosmological parameters in different dark energy models, including the $Λ$CDM model, the $w$CDM model and the CPL model, and conclude that the distance priors provide consistent constraints on the relevant cosmological parameters compared to those from the full $Planck$ 2018 data release.

description: We consider the scattering of two color dipoles (e.g., heavy quarkonium states) at low energy - a QCD analog of Van der Waals interaction. Even though the couplings of the dipoles to the gluon field can be described in perturbation theory, which leads to the potential proportional to (N_c^2-1)/R^{7}, at large distances R the interaction becomes totally non-perturbative. Low-energy QCD theorems are used to evaluate the leading long-distance contribution \sim (N_f^2-1)/(11N_c - 2N_f)^2 R^{-5/2} exp(-2 μR) (μis the Goldstone boson mass), which is shown to arise from the correlated two-boson exchange. The sum rule which relates the overall strength of the interaction to the energy density of QCD vacuum is derived. Surprisingly, we find that when the size of the dipoles shrinks to zero (the heavy quark limit in the case of quarkonia), the non-perturbative part of the interaction vanishes more slowly than the perturbative part as a consequence of scale anomaly. As an application, we evaluate elastic πJ/ψand πJ/ψ\to πψ' cross sections.

description: Light curves of the Z Cam type dwarf nova AT Cnc observed during standstill in 2016 and 2018 are analyzed. On the time scale of hours, previous reports on periodicities, in particular the presence of negative superhumps, could not be confirmed. Instead, a modulation with a period equal to the spectroscopic orbital period was detected which we thus interpret as a manifestations of the binary revolution. It enables us to derive a more accurate value of 0.201634 $\pm$ 0.000005 days (or its alias of 0.021580 days) for the period. AT Cnc also exhibits a hitherto unreported modulation of 25.731 $\pm$ 0.005 min, stable in period but not in amplitude over the entire time base of two years of the observations. We tentatively interpret this modulation in the context of an intermediate polar model for the system.

description: In an effort to understand the potential role of microRNAs (miRNAs) in mammary-gland stem or progenitor cells, miRNA microarrays were performed on subpopulations of the mouse mammary epithelial cell (MEC) line COMMA-DβGeo. This cell line contains a heterogeneous subpopulation of progenitors characterized by the expression of stem cell antigen 1 (Sca-1; encoded by Ly6a). Microarray analysis indicated that the Sca-1 subpopulations have distinct miRNA expression profiles. Functional studies were performed on miR-205, which was highly expressed in the Sca-1-positive (Sca-1+) cells. When miR-205 was overexpressed in vitro, the COMMA-DβGeo cells underwent several significant morphological and molecular changes. miR-205 overexpression led to an expansion of the progenitor-cell population, decreased cell size and increased cellular proliferation. In addition, the colony-forming potential of the two Sca-1 subpopulations was increased. Target prediction for miR-205 indicated that it might regulate the expression of the tumor-suppressor protein PTEN. Overexpression studies using reporter constructs confirmed that PTEN expression is regulated by miR-205. In addition to PTEN, several other putative and previously validated miR-205 targets were identified by microarray analysis, including the previously reported miR-205 targets ZEB1 and ZEB2. Additionally, in normal mouse MECs, high expression of miR-205 was observed in stem-cell-enriched cell populations isolated by FACS using established cell-surface markers.
Design, Modeling, and Power Electronic Control for Transient Stabilization of Power Grids Using Flywheel Energy Storage Systems

description: There is much interest in implementing more wind power plants in future electric energy systems. However, because wind power is unpredictable and difficult to control, large sudden disturbances in wind power generation can cause high deviations in frequency and voltage or even transient instabilities. To address these concerns, one possible solution is to add fast energy storage, such as flywheel energy storage systems. Flywheels can respond faster than conventional generators and could stabilize the system until slower generators can respond. The following approach for transient stabilization using flywheels is proposed. First, the dynamic model for the interconnected system is obtained so that control using the flywheel can be designed and
tested for provable performance. Next, flywheels are placed at each bus with wind generators, which are
the potential disturbance locations. Then, a variable speed drive controller for flywheels is designed
using time-scale separation and nonlinear passivity-based control logic. Switches in the power electronics
interfacing between the flywheel and the rest of the power grid are controlled in order to regulate both the
flywheel speed and the power electronic currents. The controller set points are chosen so that the
flywheel absorbs the wind power disturbance and the rest of the system is minimally affected. Finally,
the power electronics are sized to ensure that the flywheel can handle a certain range of disturbances.
Due to the complex nature of large interconnected power systems, automated methods are
implemented for both the modeling and control of power systems. An automated approach is presented
for symbolically deriving the dynamic model of power systems using the Lagrangian formulation from
classical mechanics, where the model is described in terms of the energy functions of the system.
Another automated method is introduced for symbolically deriving the control law using passivity-based
control, where the control law is derived from desired closed-loop energy functions.
Finally, in the actual implementation of flywheels, one major design challenge is to support the high
speed rotor. A passive magnetic bearing design is presented and the resultant magnetic fields and forces
are computed, demonstrating that stable levitation of the flywheel in all directions is achieved.

description: During the evolution of proto-planetary disc, photo-evaporations of both central and external stars play important roles. Considering the complicated radiation surroundings in the clusters, where the star formed, the proto-planetary discs survive in different lifetimes due to flyby events. In this paper, we mainly focus on the disc around a T Tauri star, which encounters with another main-sequence star with different temperatures in hyperbolic orbits with different peri-center distances, eccentricities and inclinations. We find the criterion for gap-opening due to photo-evaporation of central star after the flyby event. A gap is opened in the late stage of gas disc, and induce that the gap only influence the planet formation and migration limitedly. If the flyby orbit has a moderate value of peri-center distance, which weakly depends on the eccentricity and inclination, the external photo-evaporation lead to a maximum mass loss during the flyby event. Flyby stars in orbits with smaller eccentricities or larger inclinations induce larger mass loss. Adopting a simple multiple flyby models, we conclude that in open clusters, gas discs usually survive in typical lifetimes between 1 and 10 Myr, except there are many massive stars in dense open clusters. In globular clusters, discs disperse very quickly and hardly produce the gas giant planets. The fast-depleted discs are probably responsible for the null detection of giant planets in globular clusters.

description: A bipartite state $ρ^{AB}$ has a $k$-symmetric extension if there exists a $k+1$-partite state $ρ^{AB_1B_2\ldots B_k}$ with marginals $ρ^{AB_i}=ρ^{AB}, \forall i$. The $k$-symmetric extension is called bosonic if $ρ^{AB_1B_2\ldots B_k}$ is supported on the symmetric subspace of $B_1B_2\ldots B_k$. Understanding the structure of symmetric/bosonic extension has various applications in the theory of quantum entanglement, quantum key distribution and the quantum marginal problem. In particular, bosonic extension gives a tighter bound for the quantum marginal problem based on seperability. In general, it is known that a $ρ^{AB}$ admitting symmetric extension may not have bosonic extension. In this work, we show that when the dimension of the subsystem $B$ is $2$ (i.e. a qubit), $ρ^{AB}$ admits a $k$-symmetric extension if and only if it has a $k$-bosonic extension. Our result has an immediate application to the quantum marginal problem and indicates a special structure for qubit systems based on group representation theory.

description: We present a calculation for the $K^+\toπ^+ π^0 $ decay amplitude using a quenched simulation of lattice QCD with the Wilson quark action at $β=6/g^2=6.1$. The decay amplitude is extracted from the ratio, the $K\toππ$ three-point function divided by either $K$ and $π$ meson two-point functions or $K$ meson two-point function and I=2 $ππ$ four-point function; the two different methods yield consistent results. Finite size effects are examined with calculations made on $24^3\times 64$ and $32^3\times 64$ lattices, and are shown that they are explained by one-loop effects of chiral perturbation theory. The lattice amplitude is converted to the continuum value by employing a one-loop calculation of chiral perturbation theory, yielding a value in agreement with experiment if extrapolated to the chiral limit. We also report on the $K$ meson $B$ parameter $B_K$ obtained from the $K^+\toπ^+π^0$ amplitude using chiral perturbation theory.

The long-distance piece is estimated using chiral perturbation theory techniques and large-N_C considerations, leading to a consistent description of the pi^0-->e+ e-, eta-->mu+ mu- and K_L-->mu+ mu- branching ratios.

description: In various real-world problems, we are presented with classification problems with positive and unlabeled data, referred to as presence-only responses. In this article we study variable selection in the context of presence only responses where the number of features or covariates p is large. The combination of presence-only responses and high dimensionality presents both statistical and computational challenges. In this article, we develop the PUlasso algorithm for variable selection and classification with positive and unlabeled responses. Our algorithm involves using the majorization-minimization framework which is a generalization of the well-known expectation-maximization (EM) algorithm. In particular to make our algorithm scalable, we provide two computational speed-ups to the standard EM algorithm. We provide a theoretical guarantee where we first show that our algorithm converges to a stationary point, and then prove that any stationary point within a local neighborhood of the true parameter achieves the minimax optimal mean-squared error under both strict sparsity and group sparsity assumptions. We also demonstrate through simulations that our algorithm outperforms state-of-the-art algorithms in the moderate p settings in terms of classification performance. Finally, we demonstrate that our PUlasso algorithm performs well on a biochemistry example. Supplementary materials for this article are available online.

A Model for High Temperature Superconductors using the Extended Hubbard Model
Creators: name: de Mello, Evandro V. L.
Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We derive a method to study the phase diagram for high temperature superconductors (HTCS). Our starting point is the Hubbard Hamiltonian with a weak attractive interaction to obtain the formation of bound pairs. We consider this attractive potential at different positions for different compounds accordingly to the experimental results of the coherence length. We then construct a wave function of the BCS type by a variational method using the Fourier transform of this extended Hubbard potential and then derive an energy gap equation. This approach allows us to obtain the critical temperature as function of the doping concentration which gives very good agreement with the experimental phase diagrams of YBaCuO and La(Sr,Ba)CuO compounds.

Light-Front Quark Model Analysis of Exclusive $0^{-}$$\to$$0^{-}$ Semileptonic Heavy Meson Decays

Year: 1999

description: We present the analysis of exclusive $0^{-}$$\to$$0^{-}$ semileptonic heavy meson decays using the constituent quark model based on the light-front quantization. Our model is constrained by the variational principle for the well-known linear plus Coulomb interaction motivated by QCD. Our method of analytic continuation to obtain the weak form factors avoids the difficulty associated with the contribution from the nonvalence quark-antiquark pair creation. Our numerical results for the heavy-to-heavy and heavy-to-light meson decays are in a good agreement with the available experimental data and the lattice QCD results. In addition, our model predicts the two unmeasured mass spectra of $^{1}S_{0}(b\bar{b})$ and $^{3}S_{1}(b\bar{s})$ systems as $M_{b\bar{b}}$=9657 MeV and $M_{b\bar{s}}$= 5424 MeV.

Meta: Countering the information deluge with content feeds
Creators: name: Wade, Alex
Publisher: name: Zenodo
Year: 2019

description: The Meta project at the Chan Zuckerberg Initiative (CZI) is an innovative, intuitive way of empowering scientists to keep up to date with the literature. As with many modern online systems, the app centers around feeds, that in this case are personalized recommendations of scientific papers tailored to individual's research interests. In this presentation, we describe the vision and value proposition of the Meta product, as well as the unique, methodological perspective that differentiates Meta from other services in this field (Semantic Scholar, PubMed, etc). We describe the underlying methods we use to index the entire biomedical literature and support the creation of feeds through curation and data analysis. We also discuss how this contributes to the CZI vision of open science more generally.

description: Accelerating the calculations of finite-temperature thermodynamic properties is a major challenge for rational materials design. Reliable methods can be quite expensive, limiting their effective applicability in autonomous high-throughput workflows. Here, the 3-phonons quasi-harmonic approximation (QHA) method is introduced, requiring only three phonon calculations to obtain a thorough characterization of the material. Leveraging a Taylor expansion of the phonon frequencies around the equilibrium volume, the method efficiently resolves the volumetric thermal expansion coefficient, specific heat at constant pressure, the enthalpy, and bulk modulus. Results from the standard QHA and experiments corroborate the procedure, and additional comparisons are made with the recently developed self-consistent QHA. The three approaches - 3-phonons, standard, and self- consistent QHAs - are all included within the automated, open-source framework AFLOW, allowing automated determination of properties with various implementations within the same framework.

description: We study properties of the oscillation effects in the matter of the Earth on antineutrino fluxes from supernovae. We show that these effects can provide explanation of the difference in the energy spectra of the events detected by Kamiokande-2 and IMB detectors from SN1987A as well as the absence of high-energy events with $E\gta 40$ MeV. This explanation requires the neutrino oscillation parameters $Δm^2$ and $\sin^2 2θ$ to be in the region of the LMA solution of the solar neutrino problem and the normal mass hierarchy if $|U_{e 3}|^2\gta 10^{-3}$. The hierarchy can be inverted if $|U_{e 3}|^2\ll 10^{-3}$. The solution of the solar neutrino problem based on $ν_e$-conversion to a pure sterile state is disfavoured by SN1987A data.

description: Machine learning has increasingly gained more popularity with its incredibly powerful ability to make predictions or calculated suggestions for large amounts of data. We apply the machine learning classification to 85,613,922 objects in the $Gaia$ data release 2, based on the combination of the Pan-STARRS 1 and AllWISE data. The classification results are cross-matched with Simbad database, and the total accuracy is 91.9%. Our sample is dominated by stars, $\sim$ 98%, and galaxies makes up 2%. For the objects with negative parallaxes, about 2.5\% are galaxies and QSOs, while about 99.9% are stars if the relative parallax uncertainties are smaller than 0.2. Our result implies that using the threshold of 0 $< σ_π/π
