description: Based on SDSS data, we have selected a sample of nine edge-on spiral galaxies with bulges whose major axes show a high inclination to the disk plane. Such objects are called polar-bulge galaxies. They are similar in their morphology to polar-ring galaxies, but the central objects in them have small size and low luminosity. We have performed a photometric analysis of the galaxies in the g and r bands and determined the main characteristics of their bulges and disks. We show that the disks of such galaxies are typical for the disks of spiral galaxies of late morphological types. The integrated characteristics of their bulges are similar to the parameters of normal bulges. The stellar disks of polar-bulge galaxies often show large-scale warps, which can be explained by their interaction with neighboring galaxies or external accretion from outside.

description: Auf der Nordfriesischen Insel Sylt wurde seit 2006 bei Tinnum eine wikingerzeitliche Siedlung mit zahlreichen Grubenhäusern gegraben. Der nur saisonal genutzte Ort diente Handwerk und Handel und war offenbar von der Nordsee her erreichbar. In der Feuerstelle eines Hauses fanden sich nicht nur ein Webgewicht, sondern auch verkohlte Pflanzenreste. Die archäobotanische Untersuchung von Helmut Kroll ergab sehr kleine und leichte Roggenkörner sowie eine „aberwitzige“ Menge kleiner Unkrautsaat. Diese Probe ist Ausgesiebtes von Roggen und damit ein seltener Beleg für den Gebrauch von Sieben. Wie und warum das Ausgesiebte in die Feuerstelle gelangte, ist nicht sicher zu klären.

description: We present the first experimental application of coherent Raman spectroscopy (CRS) on the ro-vibrational $ν_2$ mode spectrum of methane (CH$_4$). Ultrabroadband femtosecond/picosecond (fs/ps) CRS is performed in the molecular fingerprint region from 1100 to 2000 cm$^{-1}$, employing fs laser-induced filamentation as the supercontinuum generation mechanism to provide the ultrabroadband excitation pulses. We introduce a time-domain model of the CH$_4$ $ν_2$ CRS spectrum, including all five ro-vibrational branches allowed by the selection rules $Δv = 1$, $ΔJ = 0$, $\pm1$, $\pm2$; the model includes collisional linewidths, computed according to a modified exponential gap scaling law and validated experimentally. The use of ultrabroadband CRS for in situ monitoring of the CH$_4$ chemistry is demonstrated in a laboratory CH$_4$/air diffusion flame: CRS measurements in the fingerprint region, performed across the laminar flame front, allow the simultaneous detection of molecular oxygen (O$_2$), carbon dioxide (CO$_2$), and molecular hydrogen (H$_2$), along with CH$_4$. Fundamental physicochemical processes, such as H$_2$ production via CH$_4$ pyrolysis, are observed through the Raman spectra of these chemical species. In addition, we demonstrate ro-vibrational CH$_4ν_2$ CRS thermometry, and we validate it against CO$_2$ CRS measurements. The present technique offers an interesting diagnostics approach to in situ measurement of CH$_4$-rich environments, e.g., in plasma reactors for CH$_4$ pyrolysis and H$_2$ production.

Legitimacy, Success and rebellion in Chechnya: the rise and fall of Chechen Independence
Creators: name: Tomas, Alison
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This paper traces rebel legitimacy in Chechnya from 1990-2007 to determine the impact of heightened legitimacy on rebel outcomes of success. The findings of this analysis suggest that the ability of Chechen rebels to obtain legitimacy amongst national political elites, the international community, and the local population contributed significantly to the movement’s ability to access resources, networks, and materials that contributed to the movement’s initial success in the early 1990’s. Consequently, reduced legitimacy in the later years of the rebellion facilitated challenges to rebel ability to access materials and avenues that support successful rebellion outcomes.

description: Various Fe-vacancy orders have been reported in tetragonal Fe1-xSe single crystals and nanowires/nanosheets, which are similar to those found in alkali metal intercalated A1-xFe2-ySe2 superconductors. Here we report the in-situ angle-resolved photoemission spectroscopy study of Fe-vacancy disordered and ordered phases in FeSe multi-layer thin films grown by molecular beam epitaxy. Low temperature annealed FeSe films are identified to be Fe-vacancy disordered phase and electron doped. Further long-time low temperature anneal can change the Fe-vacancy disordered phase to ordered phase, which is found to be semiconductor/insulator with (root 5) x (root 5) superstructure and can be reversely changed to disordered phase with high temperature anneal. Our results reveal that the disorder-order transition in FeSe thin films can be simply tuned by vacuum anneal and the (root 5) x (root 5) Fe-vacancy ordered phase is more likely the parent phase of FeSe.

description: Let $f \colon \mathcal{M} \to \mathbb{R}$ be a Lipschitz and geodesically convex function defined on a $d$-dimensional Riemannian manifold $\mathcal{M}$. Does there exist a first-order deterministic algorithm which (a) uses at most $O(\mathrm{poly}(d) \log(ε^{-1}))$ subgradient queries to find a point with target accuracy $ε$, and (b) requires only $O(\mathrm{poly}(d))$ arithmetic operations per query? In convex optimization, the classical ellipsoid method achieves this. After detailing related work, we provide an ellipsoid-like algorithm with query complexity $O(d^2 \log^2(ε^{-1}))$ and per-query complexity $O(d^2)$ for the limited case where $\mathcal{M}$ has constant curvature (hemisphere or hyperbolic space). We then detail possible approaches and corresponding obstacles for designing an ellipsoid-like method for general Riemannian manifolds.

description: Two-particle pseudorapidity correlations of hadrons produced in Pb+Pb collisions at 2.76 TeV at the CERN Large Hadron Collider are analyzed in the framework of a model based on viscous 3+1-dimensional hydrodynamics with the Glauber initial condition. Based on our results, we argue that the correlation from resonance decays, formed at a late stage of the evolution, produce significant effects. In particular, their contribution to the event averages of the coefficients of the expansion in the Legendre basis explain 60-70% of the experimental values. We have proposed an accurate way to compute these coefficients, independent of the binning in pseudorapidity, and tested a double expansion of the two-particle correlation function in the azimuth and pseudorapidity, which allows us to investigate the pseudorapidity correlations between harmonics of the collective flow. In our model, these quantities are also dominated by non-flow effects from the resonance decays. Finally, our method can be used to compute higher-order cumulants for the expansion in orthonormal polynomials which offers a suitable way of eliminating the non-flow effects from the correlation analyses.

Unbiased Delayed Feedback Label Correction for Conversion Rate Prediction

description: Conversion rate prediction is critical to many online applications such as digital display advertising. To capture dynamic data distribution, industrial systems often require retraining models on recent data daily or weekly. However, the delay of conversion behavior usually leads to incorrect labeling, which is called delayed feedback problem. Existing work may fail to introduce the correct information about false negative samples due to data sparsity and dynamic data distribution. To directly introduce the correct feedback label information, we propose an Unbiased delayed feedback Label Correction framework (ULC), which uses an auxiliary model to correct labels for observed negative feedback samples. Firstly, we theoretically prove that the label-corrected loss is an unbiased estimate of the oracle loss using true labels. Then, as there are no ready training data for label correction, counterfactual labeling is used to construct artificial training data. Furthermore, since counterfactual labeling utilizes only partial training data, we design an embedding-based alternative training method to enhance performance. Comparative experiments on both public and private datasets and detailed analyses show that our proposed approach effectively alleviates the delayed feedback problem and consistently outperforms the previous state-of-the-art methods.

description: Charged plasma and Fermi liquid are two distinct states of electronic matter intrinsic to dilute two-dimensional electron systems at elevated and low temperatures, respectively. Probing their thermodynamics represents challenge because of lacking an adequate technique. Here we report thermodynamic method to measure the entropy per electron in gated structures. Our technique appears to be three orders of magnitude superior in sensitivity to the ac calorimetry, allowing entropy measurements with only $10^8$ electrons. This enables us to investigate the correlated plasma regime, previously inaccessible experimentally in two-dimensional electron systems in semiconductors. In experiments with clean two-dimensional electron system in Si-based structures we traced entropy evolution from the plasma to Fermi-liquid regime by varying electron density. We reveal that the correlated plasma regime can be mapped onto the ordinary non-degenerate Fermi gas with an interaction-enhanced temperature dependent effective mass. Our method opens up new horizons in studies of low-dimensional electron systems.

description: A diode, a device allowing unidirectional signal transmission, is a fundamental element of logic structures and lies in the heart of modern information systems. Spin wave or magnon, representing a collective quasi-particle excitation of the magnetic order in magnetic materials, is a promising candidate of information carrier for the next generation energy-saving technologies. Here we propose a scalable and reprogrammable pure spin wave logic hardware architecture using domain walls and surface anisotropy stripes as waveguides on a single magnetic wafer. We demonstrate theoretically the design principle of the simplest logic component, a spin wave diode, utilizing the chiral bound states in a magnetic domain wall with Dzyaloshiskii-Moriya interaction, and confirm its performance through micromagnetic simulations. Our findings open a new vista for realizing different types of pure spin wave logic components and finally achieving an energy-efficient and hardware-reprogrammable spin wave computer.

The Failing Agenda

description: Scholars of the presidency have focused their attention on the factors that correlate with legislative success while also assuming that presidents want to avoid legislative failures at all costs. However, researchers have yet to advance an explanation for why presidential policy proposals succeed at such a low rate when presidents should be able to avoid these types of failures if they wished based on their knowledge of those correlates of success. This paper examines previous work on presidential success in Congress and hypothesizes about factors that could lead presidents to intentionally pursue items that are likely to fail. Those hypotheses are then used to develop a theory of presidential motivation - that presidents seek the maximum possible effect on public policy outcomes - by which we can better evaluate American presidents. I conclude by discussing the implications of this theory for future study of the presidency.

description: Active gas accretion onto the Milky Way is observed in an object called the Smith Cloud, which contains several million solar masses of neutral and warm ionized gas and is currently losing material to the Milky Way, adding angular momentum to the disk. It is several kpc in size and its tip lies two kpc below the Galactic plane. It appears to have no stellar counterpart, but could contain a stellar population like that of the dwarf galaxy Leo P. There are suggestions that its existence and survival require that it be embedded in a dark matter halo of a few 10^8 solar masses.

description: Plant hormones (PHs) or phytohormones are signaling molecules produced within plants that influence plant growth, seed germination, fruit maturation, and fruit ripening and control physiological processes including embryogenesis, regulation of organ size, pathogen defense, and reproductive developments. Methyl salicylate (MeSA), synthesized in plants from salicylic acid (SA), is a plant hormone that plays an important role in the resistance of plants to pathogens, thermogenesis in some flowers, and flower durability. Ion mobility spectrometry (IMS) is a fast, inexpensive, and sensitive technique with growing applications in the analysis of various classes of analytes. Furthermore, as there are different types of portable IMS, this technique can be used for the on-site analysis of compounds released from plants with fast repose time (few millisecond) indicating the importance of the development of IMS-based methods for chemical analysis in the field of agriculture, plant science, and food chemistry. In this work, an IMS-based method was developed to exploit the advantages of SPME, MCC, and IMS for the fast and sensitive analysis of real samples in a complex matrix. The SPME−MCC−IMS method was employed for the quantitative
 analysis of MeSA in tomato leaves.

A Comparison of Sponsorship Recognition Ability Among UNC Student Men's Basketball Fans

description: In 2003, the University of North Carolina-Chapel Hill (UNC) was unable to completely cover its scholarship budget through traditional means, due in part to a rise in tuition rates (Chapel Hill News, 2003). The pattern of elaborate athletic-related spending among competitor universities forced UNC to explore additional revenue streams that could potentially bolster their financial status, with specific attention towards the prospect of commercial signage within Kenan Stadium and the Dean E. Smith Center for the first time (Dick Baddour, personal communication, March 10, 2004). The study examined the recall and recognition ability of UNC students with respect to commercial sponsors of UNC men's basketball games. The findings showed a significant difference between upperclassmen and graduate students on the basis of sponsor recognition ability, however no difference in recognition between genders and a weak relationship between recognition ability and games attended.

description: Our goal is to provide a robust estimate of the metal content of the ICM in massive clusters. We make use of published abundance profiles for a sample of ~60 nearby systems, we include in our estimate uncertainties associated to the measurement process and to the almost total lack of measures in cluster outskirts. We perform a first, albeit rough, census of metals finding that the mean abundance of the ICM within r_180 is very poorly constrained, 0.06Z_sol < Z < 0.26Z_sol, and presents no tension with expectations. Similarly, the question of if and how the bulk of the metal content in clusters varies with cosmic time, is very much an open one. A solid estimate of abundances in cluster outskirts could be achieved by combining observations of the two experiments which will operate on board Athena, the XIFU and the WFI, provided they do not fall victim to the de-scoping process that has afflicted several space observatories over the last decade.

description: Existing planet-finding spectrometers are limited by systematic errors that result from their seeing-limited design. Of particular concern is the use of multi-mode fibers (MMFs), which introduce modal noise and accept significant amounts of background radiation from the sky. We present the design of a single-mode fiber-based acquisition camera for a diffraction-limited spectrometer named "iLocater." By using the "extreme" adaptive optics (AO) system of the Large Binocular Telescope (LBT), iLocater will overcome the limitations that prevent Doppler instruments from reaching their full potential, allowing precise radial velocity (RV) measurements of terrestrial planets around nearby bright stars. The instrument presented in this paper, which we refer to as the acquisition camera "demonstration system," will measure on-sky single-mode fiber (SMF) coupling efficiency using one of the 8.4m primaries of the LBT in fall 2015.

description: Tobacco and alcohol are the predominant etiologic factors for oral cancer. Studies show an association between disease severity and tobacco cessation. Relationship between oral biopsy diagnosis and risk factor cessation is unknown. Patients diagnosed with hyperkeratosis, dysplasia or carcinoma were sent questionnaires addressing demographics and risk factor use. Statistical analyses assessed whether behavior change was associated with the biopsy procedure and whether that change was related to diagnostic or demographic categories. Response rate was 37.4% (605/1619). Higher percentages of subjects with more severe diagnoses quit cigarettes and alcohol following biopsy. Younger respondents were less likely to quit smoking prior to biopsy and more likely to be still smoking (p<0.01). For patients with suspicious oral lesions, clinicians should be aware that oral biopsy diagnosis is an important tool against risk factor addiction. Younger patients are more likely to continue to be cigarette users even after controlling for severity of diagnosis.

Indirect techniques have revealed that phase Q might be composed of two subphases, one of them associated with sulfide. Here we provide experimental evidence that noble gases trapped within meteoritic sulfides present chemically- and thermally-driven behavior patterns that are similar to Q-gases. We therefore suggest that phase Q is likely composed of two subcomponents: carbonaceous phases and sulfides. In situ decay of iodine at concentrations levels consistent with those reported for meteoritic sulfides can reproduce the 129Xe excess observed for Q-gases relative to fractionated Solar Wind. We suggest that the Q-bearing sulfides formed at high temperature and could have recorded the conditions that prevailed in the chondrule-forming region(s).

description: Hot-carrier solar cells are envisioned to utilize energy filtering to extract power from photogenerated electron-hole pairs before they thermalize with the lattice, and thus potentially offer higher power conversion efficiency compared to conventional, single absorber solar cells. The efficiency of hot-carrier solar cells can be expected to strongly depend on the details of the energy filtering process, a relationship which to date has not been satisfactorily explored. Here, we establish the conditions under which electron-hole separation in hot-carrier solar cells can occur reversibly, that is, at maximum energy conversion efficiency. We thus focus our analysis on the internal operation of the hot-carrier solar cell itself, and in this work do not consider the photon-mediated coupling to the sun. After deriving an expression for the voltage of a hot-carrier solar cell valid under conditions of both reversible and irreversible electrical operation, we identify separate contributions to the voltage from the thermoelectric effect and the photovoltaic effect. We find that, under specific conditions, the energy conversion efficiency of a hot-carrier solar cell can exceed the Carnot limit set by the intra-device temperature gradient alone, due to the additional contribution of the quasi-Fermi level splitting in the absorber. We also establish that the open-circuit voltage of a hot-carrier solar cell is not limited by the band gap of the absorber, due to the additional thermoelectric contribution to the voltage. Additionally, we find that a hot-carrier solar cell can be operated in reverse as a thermally driven solid-state light emitter. Our results help explore the fundamental limitations of hot-carrier solar cells, and provide a first step towards providing experimentalists with a guide to the optimal configuration of devices.

description: In this paper, we explore the possibilities and limitations of recovering sparse signals in an online fashion. Employing a mean field approximation to the Bayes recursion formula yields an online signal recovery algorithm that can be performed with a computational cost that is linearly proportional to the signal length per update. Analysis of the resulting algorithm indicates that the online algorithm asymptotically saturates the optimal performance limit achieved by the offline method in the presence of Gaussian measurement noise, while differences in the allowable computational costs may result in fundamental gaps of the achievable performance in the absence of noise.

The effects of attention deficit and hyperactivity disorder (ADHD) on clinical measures of concussion
Creators: name: Littleton, Ashley Cameron
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The purpose of this study was to examine the effects of attention deficit hyperactivity disorder (ADHD) and stimulant medications on concussion measures in physically active individuals, and examine differences in practice effects between an un-medicated ADHD group and matched controls. All participants were administered CNS Vital Signs (CNSVS), the Balance Error Scoring System (BESS), and the Standardized Assessment of Concussion (SAC) on three separate testing sessions (the ADHD group completed session one and two on medication and session three off medication), each 7-9 days apart. The ADHD group had diminished scores on measures of overall neurocognition, psychomotor speed and processing speed; these scores improved with medication (p<0.05).Our study suggests that it is especially important to obtain a baseline measure in individuals with ADHD, because it is difficult to compare scores to normative data and individuals with ADHD should also be tested on their medication if possible.

description: Characterization of the minute cosmic microwave background polarization signature requires multi-frequency, high-throughput precision instrument systems. We have previously described the detector fabrication of a 40 GHz focal plane and now describe the fabrication of detector modules for measurement of the CMB at 90 GHz. The 90 GHz detectors are a scaled version of the 40 GHz architecture where, due to smaller size detectors, we have implemented a modular (wafer level) rather than the chip-level architecture. The new fabrication process utilizes the same design rules with the added challenge of increased wiring density to the 74 TES's as well as a new wafer level hybridization procedure. The hexagonally shaped modules are tile-able, and as such, can be used to form the large focal planes required for a space-based CMB polarimeter. The detectors described here will be deployed in two focal planes with 7 modules each in the Johns Hopkins University led ground-based Cosmology Large Angular Scale Surveyor (CLASS) telescope.

description: Graph-based neural network models are gaining traction in the field of representation learning due to their ability to uncover latent topological relationships between entities that are otherwise challenging to identify. These models have been employed across a diverse range of domains, encompassing drug discovery, protein interactions, semantic segmentation, and fluid dynamics research. In this study, we investigate the potential of Graph Neural Networks (GNNs) for medical image classification. We introduce a novel model that combines GNNs and edge convolution, leveraging the interconnectedness of RGB channel feature values to strongly represent connections between crucial graph nodes. Our proposed model not only performs on par with state-of-the-art Deep Neural Networks (DNNs) but does so with 1000 times fewer parameters, resulting in reduced training time and data requirements. We compare our Graph Convolutional Neural Network (GCNN) to pre-trained DNNs for classifying MedMNIST dataset classes, revealing promising prospects for GNNs in medical image analysis. Our results also encourage further exploration of advanced graph-based models such as Graph Attention Networks (GAT) and Graph Auto-Encoders in the medical imaging domain. The proposed model yields more reliable, interpretable, and accurate outcomes for tasks like semantic segmentation and image classification compared to simpler GCNNs

description: We study the geodesic motion of massive and massless test particles in the background of a particular class of multiple charge black holes in gauged supergravity theories in D = 4. We have analysed the horizon structure along with the nature of the effective potentials for the case of four equal charges. In view of the corresponding effective potentials, we have discussed all the possible orbits in detail for different values of energy and angular momentum of the incoming test particles. The periods for one complete revolution of circular orbits and the advance of perihelion of the planetary orbit have also been investigated in greater detail for massive test particles. We have also discussed the time period of unstable circular motion and cone of avoidance of massless test particles in detail. All the corresponding results obtained for massive and massless test particles are then compared accordingly.
