description: The nature of light, the existence of magnetism, the physical meaning of a vacuum are problems so deeply related to philosophy that they have been discussed for thousands of years. In this paper, we concentrate ourselves on a question that concerns the three of them: does light speed in a vacuum change when a magnetic field is present? The experimental answer to this fundamental question has not yet been given even if it has been stated in modern terms for more than a century. To fully understand the importance of such a question in physics, we review the main facts and concepts from the historical point of view.

description: It is well acknowledged that innovation is a key success factor in mobile service domain. Having creative ideas is the first critical step in the innovation process. Many studies suggest that customers are a valuable source of creative ideas. However, the literature also shows that adults may be constrained by existing technology frames, which are known to hinder creativity. Instead young children (aged 7-12) are considered digital natives yet are free from existing technology frames. This led us to study them as a potential source for creative mobile service ideas. A set of 41,000 mobile ideas obtained from a research project in 2006 granted us a unique opportunity to study the mobile service ideas from young children. We randomly selected two samples of ideas (N=400 each), one contained the ideas from young children, the other from adults (aged 17-50). These ideas were evaluated by several evaluators using an existing creativity framework. The results show that the mobile service ideas from the young children are significantly more original, transformational, implementable, and relevant than those from the adults. Therefore, this study shows that young children are better sources of novel and quality ideas than adults in the mobile services domain. This study bears significant contributions to the creativity and innovation research. It also indicates a new and valuable source for the companies that seek for creative ideas for innovative products and services.

Understanding Developmental Plasticity in Coloration Among Playa Populations of S. bombifrons
Creators: name: Carroll, Dylan Gerard
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Developmental plasticity can lead to genetically similar organisms displaying drastically different
phenotypes in direct response to environmental cues. This research examined whether phenotypic
plasticity in coloration occurs among spadefoot toad tadpoles, Spea bombifrons. In the wild, S.
bombifrons tadpoles inhabit ponds exhibiting a wide range of color environments, and previous
observations had suggested that these tadpoles might engage in background color matching. I
specifically evaluated whether these tadpoles can alter their coloration in direct response to background
coloration or light intensity. I found that substrate coloration influences the coloration of spadefoot
tadpoles and metamorphs, as those raised on a lighter substrate developed a lighter coloration than
those raised on a darker substrate. Furthermore, this plasticity was found to be indeterminate, as
juvenile toads not subjected to substrate or light treatments for a month lost the coloration differences
found between them at the tadpole and metamorph stages. The results of this experiment could help
display how developmental plasticity evolves to respond to environmental cues and its role in aiding the
way organisms adapt to novel environments.

description: Vertically stacked exchange coupled magnetic heterostructures of cylindrical geometry can host complex noncolinear magnetization patterns. By tuning the interlayer exchange coupling between a layer accommodating magnetic vortex state and an out-of-plane magnetized layer, one can efficiently realize new topological chiral textures such as cone state vortices and circular stripe domains. We study how the number of circular stripes can be controlled by both the interlayer exchange coupling and the sample geometrical parameters. By varying geometrical parameters, a continuous phase transition between the homogeneous state, cone state vortex, circular stripe domains, and the imprinted vortex takes place, which is analysed by full scale micromagnetic simulations. The analytical description provides an intuitive pictures of the magnetization textures in each of these phases. The possibility to realize switching between different states allows for engineering magnetic textures with possible applications in spintronic devices.

description: We present GLASS, the Generator for Large Scale Structure, a new code for the simulation of galaxy surveys for cosmology, which iteratively builds a light cone with matter, galaxies, and weak gravitational lensing signals as a sequence of nested shells. This allows us to create deep and realistic simulations of galaxy surveys at high angular resolution on standard computer hardware and with low resource consumption. GLASS also introduces a new technique to generate transformations of Gaussian random fields (including lognormal) to essentially arbitrary precision, an iterative line-of-sight integration over matter shells to obtain weak lensing fields, and flexible modelling of the galaxies sector. We demonstrate that GLASS readily produces simulated data sets with per cent-level accurate two-point statistics of galaxy clustering and weak lensing, thus enabling simulation-based validation and inference that is limited only by our current knowledge of the input matter and galaxy properties.

Measuring inaccessible structural features from virtual models using PhotoScan, CloudCompare, and a drone-mounted camera
Creators: name: Becker, Naomi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This study focused on establishing a straightforward process to create a 3D model using photogrammetric software and drone photography allowing for the extraction of measurements of structural data from inaccessible locations. The project specified field data collection techniques, image processing workflow, and methods of measurement extraction that enabled structural measurements to be taken from the Northeast high wall of the Boone Quarry outside of Boone, NC. The study established the need for specifically tailored methods for extracting these data from 3D models in order to compensate for potential biases in the drone data collection method, as well as illuminated some potential for bias in structural measurements taken manually in the field. Using this information, projects utilizing drone imaging and photogrammetry will be able to design their data collection in a way that corrects for some of these biases and ensures a more complete data set of structural features.

C 72, 027001 (2005)] is extended to the fractional forms using the generalized fractional derivative and the fractional Nikiforov-Uvarov (NU) technique. Analytical solutions of bound states of the Schrodinger equation for the present potential are obtained in the terms of fractional Jacobi polynomials. It is demonstrated that the classical results are a special case of the present results at Elfa=Beta=1 Therefore, the present results play important role in molecular chemistry and nuclear physics.

General contact mechanics theory for randomly rough surfaces with application to rubber friction

Year: 2015
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We generalize the Persson contact mechanics and rubber friction theory to the case where both surfaces have surface roughness. The solids can be rigid, elastic or viscoelastic, and can be homogeneous or layered. We calculate the contact area, the viscoelastic contribution to the friction force, and the average interfacial separation as a function of the sliding speed and the nominal contact pressure. We illustrate the theory with numerical results for a rubber block sliding on a road surface. We find that with increasing sliding speed, the influence of the roughness on the rubber block decreases, and for typical sliding speeds involved in tire dynamics it can be neglected.

description: We report measurement of temperature dependence of phonon spectra in quasi one-dimensional metal cyanides MCN (M=Cu, Ag and Au). Ab initio lattice dynamics calculations have been performed to interpret the phonon-spectra as well as to understand the anamolous thermal expansion behavior in these compounds. We bring out the differences in the phonon mode behavior to explain the differences in the thermal expansion behavior among the three compounds. The chain-sliding modes are found to contribute maximum to the negative thermal expansion along c axis in the Cu and Ag compounds, while the same modes contribute to positive thermal expansion in the Au compound. Several low energy transverse modes lead to positive thermal expansion along a and b axis in all the compounds. The calculated elastic constants and Born effective charges are correlated with the difference in nature of bonding among these metal cyanides.

A Man Alone: Muhammad Ali Jinnah and the All-India Muslim League's Support for the British During World War II
Creators: name: Harrell, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: During World War II, the All-India Muslim League was the only major Indian independence organization to support the British war effort. This paper examines what caused the League to offer such support and how the relationship established with the British during this era impacted the League and the foundation of Pakistan. This thesis argues that the League offered support to protect the organization's politically fragile future and that League leader Muhammad Ali Jinnah furthered used the war to increase control over the party. In doing so, the League acquired a special place of power from the British yet become more homogeneous as different concepts of Pakistan were unintentionally shunned as Jinnah's pragmatic, non-definite view of the future state came to dominate the party. The result was a League that, while politically powerful, relied heavily on the will of one person and approached the Partition and creation of Pakistan with no definite goals for the new state.

description: We present our preliminary results on the asteroseismological investigations of the ZZ Ceti star GD 244. We used literature values of the effective temperature and surface gravity and utilized the White Dwarf Evolution Code of Bischoff-Kim, Montgomery and Winget (2008, ApJ, 675, 1512) to build our model grid for the seismological analysis. Five observed pulsational modes published up to now were used to find acceptable model solutions. We found that the best model fits have masses between 0.61 and 0.74 M_solar and constitute two groups with hydrogen layer masses of either ~10^{-5} or 10^{-6} M_solar. Based on a statistical analysis of a larger sample of possible model solutions, we assume that the mass of the star is below ~0.68 M_solar and the oxygen content in the centre is less than 60 percent.

description: A phenomenological study for determining the chirality structure in lepton-flavor-violating Higgs (hLFV) decays $h \to τμ$ at the LHC is presented. We estimate the effects of the $τ$ polarization in the analysis andthe importance of determining the relative visible momentum ratio $x$, and show the analysis with a collinear mass $m_{col1}$ by assuming one missing particle is appropriate. We find that the sensitivity would be generically affected up to $\pm$ $4-6$~\% in terms of the BR$(h\to τμ)$ upper bound, and show the altered bounds on the $(|y_{μτ}|, |y_{τμ}|)$ plane. We further study the benchmark scenarios, and demonstrate the sensitivity study for the chirality structure using the relative visible momentum ratio. We find that the two fully polarized cases, the $τ_R$ and $τ_L$ scenarios consistent with the recently reported excess, are distinguishable at 2$σ$ level for 1000~fb$^{-1}$. We also show that a further improved study potentially provides a similar sensitivity already for 139~fb$^{-1}$.

description: Scarcity of data and technological limitations for resource-poor languages in developing countries like India poses a threat to the development of sophisticated NLU systems for healthcare. To assess the current status of various state-of-the-art language models in healthcare, this paper studies the problem by initially proposing two different Healthcare datasets, Indian Healthcare Query Intent-WebMD and 1mg (IHQID-WebMD and IHQID-1mg) and one real world Indian hospital query data in English and multiple Indic languages (Hindi, Bengali, Tamil, Telugu, Marathi and Gujarati) which are annotated with the query intents as well as entities. Our aim is to detect query intents and extract corresponding entities. We perform extensive experiments on a set of models in various realistic settings and explore two scenarios based on the access to English data only (less costly) and access to target language data (more expensive). We analyze context specific practical relevancy through empirical analysis. The results, expressed in terms of overall F1 score show that our approach is practically useful to identify intents and entities.
Self-Ownership, Autonomy, and Non-Conventionalist Accounts of Property: A Comparison of Locke and Kant
Creators: name: Irvin, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: One of the most fundamental issues in western political philosophy is the question of property. Its nature, origin, justification, and purpose have been explored many times over. As an institution that shapes the life of its society, it stands in continuous need of explanation and justification. Most treatments of the question of property have focused on the issue of private property, a form of property where particular individuals have rights—such as rights of access, control, use, or exchange—over particular objects, parts of the world, or ideas. The focus on private property make sense, because it is the form of the institution most commonly found in the societies where western philosophy has developed. The same is true in our present society, where private property and the protection of property rights—particularly rights of exchange and rights of control—is the foundation of capitalism.
The many explorations of property have resulted in widely varying theories about its justification, or lack thereof. However, these theories can be roughly categorized into one of three strains. Theories in the first strain argue that moral claims about property rights exist independent of cultural norms, conventional practices, or laws and policy. The second strain is that of the conventionalists and most utilitarians. These theories argue that private property is justified, but that it is justified in virtue of the fact that the practice of property would be consented to and/or it is beneficial to some end, such as utility maximization. The third strain is that of Marxists and some philosophical anarchists. These theories hold that private property is inherently wrong, and that it either cannot be legitimized by consent or that claims that our current property system could be consented to are false.
One fruitful way to study the issue of property is to compare two theories that are in the same strain, against the same set of standards. The reason for this is that theories in the same strain will typically reach similar conclusions, but along different lines of argument. By utilizing a set of standards to analyze each theory’s argument, it will become clearer which line of argument is most likely to support the shared conclusions or—if neither argument supports the conclusions—if the conclusions themselves are untenable. The shared standards will also provide a framework where shared weaknesses or strengths can be more clearly identified. Thus, this paper will compare the property theories of Locke and Kant, two writers whose conclusions about private property place them in the first strain. They are of particular interest because they utilize very different lines of argument to get to their conclusions.

description: The European Space Agency's Rosetta mission to comet 67P/Churyumov-Gerasimenko has offered scientists the opportunity to study a comet in unprecedented detail. Four instruments of the Rosetta orbiter, namely, the Micro-Imaging Dust Analysis System (MIDAS), the Grain Impact Analyzer and Dust Accumulator (GIADA), the COmetary Secondary Ion Mass Analyser (COSIMA), and the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) have provided information on cometary dust particles. Cross-instrument comparisons are crucial to characterize cometary dust particles beyond the capabilities of individual sensors, as they are sensitive to different dust components. We present the first comparison between detections of the ROSINA COmet Pressure Sensor (COPS) and GIADA. These two instruments are complementary as the former is sensitive solely to volatiles of icy particles, while the latter measured the dust particle as a whole, including refractories and condensed (semi)volatiles. Our goal is to correlate the particles detected by COPS and GIADA and to assess whether they belong to a common group. We statistically analyzed the in situ data of COPS and GIADA by calculating Pearson correlation coefficients. Among the several types of particles detected by GIADA, we find that COPS particles are significantly correlated solely with GIADA fluffy agglomerates (Pearson correlation coefficient of 0.55 and p-value of $4.6\cdot 10^{-3}$). This suggests that fluffy particles are composed of both refractories and volatiles. COPS volatile volumes, which may be represented by equivalent spheres with a diameter in the range between 0.06 $μ$m and 0.8 $μ$m, are similar to the sizes of the fractal particle's subunits identified by MIDAS (i.e., 0.05-0.18 $μ$m).

Determinants of Medical Insurance Participation in Rural China
Creators: name: Lee, William
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: While China experienced rapid economic growth in the past decade, development of health care has lagged in comparison. After the collapse of the previous insurance system in the late 1970s, continuing healthcare reforms have been implemented to promote healthcare access, especially for rural households. Although research has been done to assess the outcomes of the health care reforms in China, limited studies have been done to analyze the decision-making behavior of rural households. This study investigates the impact of healthcare access on insurance participation rate in rural China. The data for this study was extracted from the China Nutrition and Health survey, a longitudinal dataset collected by the Carolina Population Center at UNC. Probit regressions were utilized to estimate the effects of healthcare access factors on insurance participation rate. The estimation results indicated that travelling time and waiting time to receive healthcare negatively impact the probability of having medical insurance. On the other hand, cost of travelling, cost of common cold treatment and the availability of necessary medicines increase the probability of having medical insurance. Among the control variables, presence of chronic illness, higher education level and employment in labor-intensive occupation contribute most significantly and positively to having medical insurance. Thus the specified decision-driving factors of this study are found to be consistent with previous research in health-seeking behavior. The result of this research suggests that additional services to improve access can further improve health insurance and healthcare utilization in rural China.

description: Light dark matter($\simeq 1-30~\rm{MeV}$) particles pair produced in electron-positron annihilation $ e^-e^+ \stackrelγ{\longrightarrow} χ\barχ$ inside the supernova core can take away the energy released in the supernova SN1987A explosion. Working within the formalism of $q$-deformed statistics (with the average value of the supernovae core temperature(fluctuating) being $T_{SN} = 30~\rm{MeV}$) and using the Raffelt's criterion on the emissivity for any new channel $\dot{\varepsilon}(e^+ e^- \to χ\overlineχ) \le 10^{19}~{erg~g^{-1}s^{-1}}$, we find that as the deformation parameter $q$ changes from $1.0$ (undeformed scenario) to $1.1$(deformed scenario), the lower bound on the scale $Λ$ of the dark matter effective theory varies from $3.3\times 10^6$ TeV to $3.2 \times 10^7$ TeV for a dark matter fermion of mass $m_χ= 30~\rm{MeV}$. Using the optical depth criteria on the free streaming of the dark matter fermion, we find the lower bound on $Λ\sim 10^{8}~\rm{TeV}$ for $m_χ= 30~\rm{MeV}$. In a scenerio,where the dark matter fermions are pair produced in the outermost sector of the supernova core (with radius $0.9 R_c \le r \le R_c$, $R_c (=10~\rm{km})$ being the supernova core radius or the radius of proto-neutron star), we find that the bound on $Λ$ ($\sim 3 \times 10^7$ TeV)obtained from SN cooling criteria (Raffelt's criteria) is comparable with the bound obtained from free streaming (optical depth criterion) for light fermion dark matter of mass $m_χ=10 - 30$ MeV.

description: Der vorliegende Forschungsbericht zeigt einmal mehr eindrücklich, wie innovativ die deutsche Textilforschung ist. Mit jedem Jahr wird deutlicher, dass Textil ein Schlüssel für die Transformation in ein klimaneutrales Zeitalter ist. Dabei stehen viele Entwicklungen im Zeichen einer umfassenden Kreislaufwirtschaft mit dem Ziel, bis 2050 in Europa klimaneutral zu sein. Angesichts der ambitionierten Ziele, die sich Politik und Wirtschaft gesteckt haben, können wir auch in der Textilforschung mit Fug und Recht von einer Zeitenwende reden. Doch diese Zeitenwende wird derzeit von verschiedenen Faktoren überschattet. So droht die Neujustierung der Mittelvergabe im Ergebnis zu Kürzungen zu führen - mit erheblichen Auswirkungen für die mittelständische Industrie. Weniger Forschungsförderung ist gerade angesichts der derzeitigen Herausforderungen der völlig falsche Weg! Vor dem Hintergrund explodierender Energie- und Rohstoffpreise, der galoppierenden Inflation und der unsicheren weltpolitischen Lage sind die Investitionsmittel in Forschung und Entwicklung gerade in den mittelständischen Unternehmen knapp. Nur mit einer weiter kraftvollen textilen Forschungslandschaft wird Deutschland seine Spitzenstellung bei hochinnovativen technischen Textilien halten und Sprunginnovationen für neue Materialien, Kreislaufwirtschaft und Klimaneutralität entwickeln können. Was das Know-how unserer Forscherinnen und Forscher angeht, kann ich aus voller Überzeugung sagen: Wir können Green Deal Textil. Um das in Deutschland und in Europa auf den unterschiedlichsten Anwendungsfeldern in der Praxis umzusetzen, braucht es eine beherzte und mutige Forschungsförderung. Forschungsvereinigungen wie das Forschungskuratorium Textil (FKT) stehen dafür als kompetenter Partner und Wissensvermittler mit viel Elan und einem großen Netzwerk in Forschung und Mittelstand bereit. Viele Expertinnen und Experten haben uns in den vergangenen Monaten mit großem Einsatz unterstützt, der textilen Forschung in Deutschland eine Richtung zu geben. Damit wollen wir Motor sein, die Branche zukunftsfest aufzustellen. Ein Anliegen, das durch die wirtschaftlichen Folgen der Corona-Pandemie und die folgenschweren Veränderungen entlang der globalen Lieferketten noch mehr an Bedeutung gewonnen hat. Noch nie waren die Herausforderungen so enorm! Für die deutsche Textilforschung ist dies nicht nur Ansporn, sondern auch Verpflichtung. Die deutschen Forschungsinstitute stehen bereit, den Wandel aktiv mitzugestalten. Politisch brauchen wir dafür neben dem nötigen Rückenwind auch die Begeisterung für eine Branche, die jeden Tag zeigt, dass Textil der Werkstoff ist, aus dem Zukunft gestaltet wird!

description: We introduce a category of vector spaces modelling full propositional linear logic, similar to probabilistic coherence spaces and to Koethe sequences spaces. Its objects are {\it rigged sequences spaces}, Banach spaces of sequences, with norms defined from pairing with finite sequences, and morphisms are bounded linear maps, continuous in a suitable topology. The main interest of the work is that our model gives a realization of the free linear logic exponentials construction.
Unrepentant Savagery: Decoding Meaning in Islamic State's Propaganda
Creators: name: Calder, Joseph M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This investigation was first inspired by the seeming contradiction between international condemnations of Islamic State and yet, the many thousands of mostly young, European supporters of Islamic State who chose to join the State during its first year.  This study is the latest manifestation of an investigation of the author into the appeal of Islamic State to European Muslims, which began with an attempt to study the motivations of foreign fighters and female muhajirat  who originated from Europe, Australia and America. Both research constraints and a IRB concerns cut that study short – this study an adaptation from that study based on the aforementioned constraints. This study asks the question “how does Islamic State market an image of religious legitimacy that resonates with its supporters despite widespread ‘mainstream’ Islamic condemnation.”
The study proceeds by examining primary source data including Islamic State audio/visual, print, social media and graphical propaganda. Special attention is paid to Islamic State’s English language magazine, Dabiq. In addition to primary sources, secondary, analytical sources examining the various uses of Islamic State propaganda are also used in order to inform a broader understanding of Islamic State. For the purposes of investigation, the author has chosen three themes of Islamic State propaganda that enhance Islamic State’s general message of religious legitimacy: brutality, victimhood and apocalyptic utopianism. Each of those themes constitutes one of the study’s three chapters. Chapters proceed by first giving an overview of the theme, then give context to how those themes have been used historically or in other jihadist movements, then examining specific examples of that theme in Islamic State propaganda before finally analyzing how each theme contributes to Islamic State’s overall message of religious legitimacy.
Automated detection of river ice using MODIS data: Examining spatial and temporal patterns in Arctic river ice breakup
Creators: name: Cooley, Sarah

description: The annual spring river ice breakup has vast consequences for northern ecosystems as
well as significant economic implications for Arctic industry and transportation. River ice
breakup research is restricted by the sparse distribution of hydrological stations in the Arctic. A
trend towards earlier ice breakup has been noted across the Arctic region, yet the specific
climatic drivers of these trends are complex and can vary both regionally and within river
systems. Consequently, understanding the response of river ice processes to a warming Arctic
requires examination of both spatial and temporal trends in breakup timing. In this paper, I
describe an automated algorithm for detecting the timing of river ice breakup using MODIS
imagery that enables identification of spatial and temporal breakup patterns at whole-river scales
and present an analysis of breakup timing on the Mackenzie, Lena, Ob and Yenisey rivers.
Through splitting the rivers into 10 km segments and classifying each river pixel as snow, ice,
mixed ice/water or open water, I am able to determine the dates of breakup from 2000-2014 with
a mean uncertainty of around +/- 1.5 days. Where temporal trends are statistically significant,
they are consistently negative, indicating an overall shift towards earlier breakup. Considerable
variability in the statistical significance and magnitude of trends along each river suggests
changing climatic drivers are impacting breakup patterns. Trends detected on the lower
Mackenzie confirm previously observed weakening ice resistance and earlier breakup timing
near the Mackenzie delta. In Siberia, the increased magnitude of trends upstream and strong
correlation between breakup initiation and whole-river breakup patterns suggests that upstream
discharge may play the dominant role in determining breakup timing. Exploratory analysis
demonstrates that this method may in the future also be used to examine types of breakup events
and assess event severity.

description: We study phase transitions and critical phenomena in nonequilibrium steady states controlled by an electric field. We employ the D3/D7 model in the presence of a charge density and electric field at finite temperatures. The system undergoes the first-order and the second-order phase transitions under the variation of the electric field in the presence of dissipation. We numerically find that the critical exponents which we define for the nonequilibrium phase transition in this model take the mean-field values.

description: We have measured the thermal conductivity along the c-axis, \k{appa}||c, parallel to ferromagnetic spin-chains of single crystals of the S = 1/2 quasi-one-dimensional spin system CsCuCl3 in magnetic fields up to 14 T, in order to investigate the thermal conductivity due to spins, \k{appa}spin, and the change of thermal conductivity corresponding to the change of the spin state. In the temperature dependence of \k{appa}||c, no contribution of \k{appa}spin has been observed, while a dip has been observed at the antiferromagnetic phase transition temperature, TN. Furthermore, it has been found that \k{appa}||c at a low temperature of 5.1 K below TN changes with increasing field perpendicular to the c-axis in good correspondence to the field-induced change of the spin state.

description: ● Initial evidence from studies that tested judgment of individual targets, when both group-membership and diagnostic individuating information are available (Cao & Banaji, 2016; Rubinstein, Jussim, & Stevens, 2018), suggests that the individuating information governs deliberate judgment, whereas group-membership still governs automatic judgment. ● These studies used novel fictitious targets (unknown to the participant prior to the study). ● Bar-Anan and Navon (2018) tested whether there is evidence for such a discrepancy in judgment of targets that are relatively familiar to the perceivers. Meaning, if the same discrepancy exists even when the individuating information is long held in memory and the perceiver has a Long history of exposure to individuating information about a group member. They tested the deliberate and automatic (IAT) evaluations of well-known black and white actors. They found that automatic preference was discrepant from the deliberate preference, often favoring the member of the dominant group. ● These results provide novel evidence and suggest that long familiarity with the members of a stigmatized group does not automatize the positive deliberate evaluation of these individuals, and does not dethrone group evaluation from its central role in the automatic evaluation of the individual. ● Social groups in their study were groups with obvious external features (black/white, young/old). ● The purpose of the present study is to see whether this discrepancy replicates with other social groups that have no visible physical characteristics. ● We will also ask people directly about their attitudes toward Gay and Straight people, to seek further evidence for the hypothesis that attitudes towards different social groups are behind the discrepancy.
Low-Complexity Blind Parameter Estimation in Wireless Systems with Noisy Sparse Signals

description: Baseband processing algorithms often require knowledge of the noise power, signal power, or signal-to-noise ratio (SNR). In practice, these parameters are typically unknown and must be estimated. Furthermore, the mean-square error (MSE) is a desirable metric to be minimized in a variety of estimation and signal recovery algorithms. However, the MSE cannot directly be used as it depends on the true signal that is generally unknown to the estimator. In this paper, we propose novel blind estimators for the average noise power, average receive signal power, SNR, and MSE. The proposed estimators can be computed at low complexity and solely rely on the large-dimensional and sparse nature of the processed data. Our estimators can be used (i) to quickly track some of the key system parameters while avoiding additional pilot overhead, (ii) to design low-complexity nonparametric algorithms that require such quantities, and (iii) to accelerate more sophisticated estimation or recovery algorithms. We conduct a theoretical analysis of the proposed estimators for a Bernoulli complex Gaussian (BCG) prior, and we demonstrate their efficacy via synthetic experiments. We also provide three application examples that deviate from the BCG prior in millimeter-wave multi-antenna and cell-free wireless systems for which we develop nonparametric denoising algorithms that improve channel-estimation accuracy with a performance comparable to denoisers that assume perfect knowledge of the system parameters.

description: Previous studies of GD 244 revealed seven pulsation frequencies (two doublets and three single periods) in the light variations of the star. The data obtained at McDonald Observatory between 2003 and 2006, and our additional measurements in 2006 and 2007 at Konkoly Observatory, allow the investigation of the long-term pulsational behaviour of GD 244. We found that the 307.1 s period component of one of the doublets show long-term, periodic amplitude modulation with a time scale of ~740 days. Possible explanations are that nonlinear resonant mode coupling is operating among the rotationally split frequency components, or two modes, unresolved in the yearly data are excited at ~307.1 s. This is the first time that such long-term periodic amplitude modulation is published on a ZZ Ceti star.
