Absolute Parallelism: Spherical Symmetry and Singularities

description: Observing the list of compatible second order equations of Absolute Parallelism (AP) found by Einstein and Mayer (they used D=4), we choose the one-parameter class of equations which take on a 3-linear form (when contra-frame density of some weight is in use). Spherically symmetric solutions to these equations are considered, and we try not to add any delta-sources (ie, $δ(x)$-sources of unknown nature) during integrations allowed due to this high symmetry. Using two different ways to fix the radius and time, we have found that only non-static solutions (except for trivial one, of course) are possible. If D=5, such solutions, looking like a single wave moving along the radius, could serve as an expanding cosmological model (with a simple Hubble diagram). With one coordinate choice (gauge), a single second order equation remains and there exist spherically symmetric solutions with arising singularities. On the other hand, a more reasonable (covariant) choice of the radius and time reduces the problem to a system of two first order equations looking like Chaplygin gas dynamics, where solutions are seemingly free of emerging singularities and gradient catastrophe.

description: Primordial gravitational waves are created during the de Sitter phase of an exponentially-expanding (inflationary) universe, due to quantum zero-point vacuum fluctuations. These waves produce fluctuations in the temperature of the Cosmic Background Radiation (CBR). We calculate the multipole moments of the correlation function for these temperature fluctuations in a spatially-closed Friedman-Robertson-Walker (FRW) cosmological model. The results are compared to the corresponding multipoles in the spatially-flat case. The differences are small unless the density parameter today, $Ω_0$, is greater than 2.

description: We obtain a constraint on the parameters of a generalized cubic Galileon gravity model exhibiting the Vainshtein mechanism by using multi-wavelength observations of the Coma Cluster. The generalized cubic Galileon model is characterized by three parameters of the turning scale associated with the Vainshtein mechanism, and the amplitude of modifying a gravitational potential and a lensing potential. X-ray and Sunyaev-Zeldovich (SZ) observations of the intra-cluster medium are sensitive to the gravitational potential, while the weak-lensing (WL) measurement is specified by the lensing potential. A joint fit of a complementary multi-wavelength dataset of X-ray, SZ and WL measurements enables us to simultaneously constrain these three parameters of the generalized cubic Galileon model for the first time. We also find a degeneracy between the cluster mass parameters and the gravitational modification parameters, which is influential in the limit of the weak screening of the fifth force.

description: In this study, we compare the difference in the impact between open access (OA) and non-open access (non-OA) articles. 1761 Nature Communications articles published from 1 Jan. 2012 to 31 Aug. 2013 are selected as our research objects, including 587 OA articles and 1174 non-OA articles. Citation data and daily updated article-level metrics data are harvested directly from the platform of nature.com. Data is analyzed from the static versus temporal-dynamic perspectives. The OA citation advantage is confirmed, and the OA advantage is also applicable when extending the comparing from citation to article views and social media attention. More important, we find that OA papers not only have the great advantage of total downloads, but also have the feature of keeping sustained and steady downloads for a long time. For article downloads, non-OA papers only have a short period of attention, when the advantage of OA papers exists for a much longer time.

Investigating the Folding and Fibril-forming Behaviors of AAN- and NDI-Containing Foldamers
Creators: name: Vulpis, Troy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Aromatic foldamers containing 1,4,5,8-naphthalenetetracarboxylic diimide (NDI) and 1,5-dialkoxynaphthalene (DAN) in alternation have been shown to assemble into supramolecular structures and, when heated, irreversibly aggregated fibrils. By replacing electron-rich DAN with similarly electron-rich aminoalkoxynaphthalene (AAN) in a similarly alternating peptide, we hypothesize that we can form similar stacked and fibril structures when the two monomers are connected by patterned charged and hydrophobic amino acids. Notably, AAN has a pKa of approximately 5, meaning pH can be used as a switch to alter the charge state of AAN, which we hypothesize can be used to alter the stacked or aggregated structure of the peptide as a whole. Presently, syntheses toward peptides with high fibril-forming propensities are being optimized, with the aim of studying their behaviors in response to pH modulation. In this work, we have also explored the π stacking and charge transfer behavior of an AAN- and NDI-containing peptide in both neutral and acidic environments.

description: Considerable progress has been made in recent years in observations of atmospheric signatures of giant exoplanets, but processes in rocky exoplanets remain largely unknown due to major challenges in observing small planets. Numerous efforts to observe spectra of super-Earths, exoplanets with masses of 1-10 Earth masses, have thus far revealed only featureless spectra. In this paper we report a 4-$σ$ detection of variability in the dayside thermal emission from the transiting super-Earth 55 Cancri e. Dedicated space-based monitoring of the planet in the mid-infrared over eight eclipses revealed the thermal emission from its dayside atmosphere varying by a factor 3.7 between 2012 and 2013. The amplitude and trend of the variability are not explained by potential influence of star spots or by local thermal or compositional changes in the atmosphere over the short span of the observations. The possibility of large scale surface activity due to strong tidal interactions possibly similar to Io, or the presence of circumstellar/circumplanetary material appear plausible and motivate future long-term monitoring of the planet.

description: COVID-19, a new disease of the coronavirus family, has engulfed the entire world. While developed countries suffered the most; India, despite its high population density, has managed to keep the number of deaths relatively low. ‘Innovation challenges’ were given by the government, its intermediaries and corporate to crowd source the ideas and to empower the citizen innovators, on the onset of a pandemic. Government and the corporate supported them by testing, prototyping help, translating their relevant ideas into products and recognition. A large number of participants including individual citizens to students, startups, traders, and entrepreneurs responded to the challenge through their simple and frugal innovations when there was an acute shortage and urgent need of creative solutions in terms of personal protection equipment (PPE), medical equipment and accessories and other health and welfare tools to aid the personal hygiene as well as a safe environment for humans. Some innovations were impromptu attempts by citizen innovators. This communication summarizes notable instances of timely innovations at various levels in the society during the crisis. Various sources such as journal articles, news articles, commercial enterprises, as well as academic and research institutions have been reviewed for the collection of the information. The relevance of these practical innovations to COVID-19, which helped the society, underlines the people’s belief that innovation can indeed help the nation conquer the crisis and if empowered, a common man is capable of converting the crisis into opportunity. The active participation by various sectors of the society and the last person from the weaker section of society, including 'women self-help groups' have highlighted a good example of the ‘quadruple helix model of innovation’ which emphasizes on constant interactions between academia, industry, government and public. There is a need to sustain, support and encourage this inquisitive mindset to create the next wave of innovation to fight any such calamity and support socioeconomic development in the future.

description: Modern signal processing (SP) methods rely very heavily on probability and statistics to solve challenging SP problems. SP methods are now expected to deal with ever more complex models, requiring ever more sophisticated computational inference techniques. This has driven the development of statistical SP methods based on stochastic simulation and optimization. Stochastic simulation and optimization algorithms are computationally intensive tools for performing statistical inference in models that are analytically intractable and beyond the scope of deterministic inference methods. They have been recently successfully applied to many difficult problems involving complex statistical models and sophisticated (often Bayesian) statistical inference techniques. This survey paper offers an introduction to stochastic simulation and optimization methods in signal and image processing. The paper addresses a variety of high-dimensional Markov chain Monte Carlo (MCMC) methods as well as deterministic surrogate methods, such as variational Bayes, the Bethe approach, belief and expectation propagation and approximate message passing algorithms. It also discusses a range of optimization methods that have been adopted to solve stochastic problems, as well as stochastic methods for deterministic optimization. Subsequently, areas of overlap between simulation and optimization, in particular optimization-within-MCMC and MCMC-driven optimization are discussed.

description: Stars with a different vertical motion relative to the galactic disk have a different average acceleration. According to Modified Newtonian Dynamics (MOND) theories they should therefore have a different average orbital velocity while revolving around the Milky Way. We show that this property can be used to constrain MOND theories by studying stars in the local neighborhood. With the {\sc Hipparcos} dataset we can only place marginal constraints. However, the forthcoming {\sc GAIA} catalogue with its significantly fainter cutoff should allow placing a stringent constraint.

Forecasting output growth and inflation with stock returns: A MIDAS approach

Subjects: subject: 150202 Financial Econometrics

description: Improving forecasts of macroeconomic indicators such as output growth and inflation is of focal interest to academics and policy makers. Because stock returns can be observed at very high frequencies, there is the question of whether high frequency information is useful for forecasting output and inflation. Furthermore, stock data is timely, whereas macro data is available only at a lag, so there is a question of whether stock returns can help to indicate the current state of the economy, i.e., "nowcasting". In this thesis, we study the predictive power of daily stock returns on output growth and inflation with Mixed Data Sampling (henceforth, MIDAS) regression models both in forecasting and nowcasting contexts. We filter the daily stock returns with a newly proposed frequency domain filter, and aggregate the daily data with MIDAS weights using estimated parameter values. We find that predictors with MIDAS regressions perform quite well in inflation forecasting. For Singapore inflation, filtered stock returns forecast better than unfiltered stock returns; for US inflation, on the other hand, unfiltered stock returns forecast better than filtered stock returns. Predictors with MIDAS regressions perform fairly well in Singapore output growth forecasting in that contemporary stock returns have higher forecasting accuracy than the benchmark model, but for the US output growth, we don't see any improvements with our MIDAS regressions.

APOE Inhibition of Remyelination and Regulation of OPC differentiation
Creators: name: Elssner, Isabel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Apolipoprotein E (APOE) interacts with the lipoprotein receptor to transport lipoproteins and facilitates ingestion of apoptotic cells, also known as efferocytosis. APOE-deficient macrophages ingest fewer apoptotic cells than wildtype cells. Because apoptotic cells are found in lesions of demyelination, we speculated that APOE and efferocytosis may be involved in remyelination. Our hypothesis is that APOE regulates OPC differentiation via the microglia secretome. To test this hypothesis, we assessed remyelination in vivo using APOE-/-, APOE2, APOE3, and APOE4 knock-in mice and in vitro using the OPC differentiation assay. In vivo, we found APOE3 mice showed delayed remyelination at the 5+2 week time point, but by 5+3 week the APOE3 variant was similar to WT. This indicates that APOE3 partly inhibits the remyelination process. Furthermore, it was found that APOE-/- had significantly more remyelination than other genotypes at the 5+1 time point, which suggests murine APOE inhibits remyelination temporarily. In vitro, the OPC differentiation assay showed that APOE3 and APOE-/- macrophage secretomes retained significantly more round and primary processes than the positive control indicating there were less factors driving initial cell differentiation. This suggests that murine APOE is required for efferocytosis and secretome content, but APOE3 may inhibit efferocytosis and alter the beneficial factors for OPC differentiation.

For moderate circuit impedance, we compute analytically the universal lineshape for the decay of the charge susceptibility along the circuit, that relates to spatial entanglement between the qubit and its electromagnetic environment. At large circuit impedance, we numerically find further spatial correlations that are specific to a true many-body state.

description: We analyze the dynamics of a network of electrically coupled, modified FitzHugh-Nagumo (FHN) oscillators. The network building-block architecture is a bidimensional squared array shaped as a torus, with unidirectional nearest neighbor coupling in both directions. Linear approximation about the origin of a single torus, reveals that the array is able to oscillate via a Hopf bifurcation, controlled by the interneuronal coupling constants. Group theoretic analysis of the dynamics of one torus leads to discrete rotating waves moving diagonally in the squared array under the influence of the direct product group $\mathbb{Z}_N\times\mathbb{Z}_N\times\mathbb{Z}_2\times\mathbb{S}^1.$ Then, we studied the existence multifrequency patterns of oscillations, in networks formed by two coupled tori. We showed that when acting on the traveling waves, this group leaves them unchanged, while when it acts on the in-phase oscillations, they are shifted in time by $ϕ.$ We therefore proved the possibility of a pattern of oscillations in which one torus produces traveling waves of constant phase shift, while the second torus shows synchronous in-phase oscillations, at $N-$ times the frequency shown by the traveling waves.

SAVing submerged aquatic vegetation: understanding preferential utilization of N forms to reduce cyanobacteria blooms in Lake Mattamuskeet, North Carolina
Creators: name: Farquhar, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Lake Mattamuskeet, located on the Albemarle-Pamlico Peninsula in North Carolina, is the largest natural freshwater lake in the state and one of the most important waterfowl wintering grounds on the United States East Coast. Since the early 1990s, the lake has lost 93% of its submerged aquatic vegetation (SAV) and has shifted to a phytoplankton-dominated lake. The wide-spread loss of SAV has corresponded with an increase in cyanobacterial, harmful algal blooms (HABs) that pose a threat to the recreational users and wildlife of the lake. Therefore, it is crucial to understand factors that promote cyanobacterial dominance, so environmental managers with Mattamuskeet National Wildlife Refuge and the NC Department of Environmental Quality can target their SAV-restoration plan at the most problematic bloom organisms. Previous scientific studies suggest that certain nitrogen forms, particularly ammonium, may selectively stimulate the growth of cyanobacteria relative to other, non-HAB forming phytoplankton groups. Our study used experimental nutrient enrichments of ammonium and nitrate on Lake Mattamuskeet waters to assess whether the growth of cyanobacteria is selectively stimulated by ammonium enrichment. Results from three experiments indicated that, in comparison with nitrate, ammonium enrichment did not selectively stimulate cyanobacteria growth relative to other phytoplankton groups (p < 0.05). Additionally, there was no selective stimulation under N limiting or P limiting conditions. Nutrient reduction strategies to decrease cyanobacteria biomass in Lake Mattamuskeet should consider nutrient loading from both ammonium and nitrate sources and also phosphorous, as there was evidence of the system being primarily P-limited in some cases.

Cyber-securitization: a Critical Discourse Analysis of the Securitization of Cyberspace in the European Union, 1993-2021

Subjects: International relations

description: Cybersecurity is emerging as a significant field of interest in International Relations. Cyber threats and harms are presented as existential security threats requiring intervention by governments. This dissertation introduces Securitisation Theory (ST) developed by the Copenhagen School before introducing the cybersecuritization framework developed by Lene Hansen and Helen Nissenbaum. The cybersecuritization framework consists of three grammatical modalities of securitizations: hypersecuritizations, everyday security practices and technifications.
 This dissertation uses the critical discourse analysis (CDA) method, specifically topoi analysis, to uncover the discursive strategies employed by the European Union (EU) in relation to cyberspace and cybersecurity. Thirty-eight EU texts (including reports, press releases, EU Parliament, framework decisions, feasibility studies, etc.) were analysed. This research discovers which argumentations are present in the discourse. Furthermore, the argumentations are considered alongside the grammatical modalities to determine how they are used to construct cyberspace as a security issue.
 Overall, this research found that 11 of 16 topos were present in EU cybersecurity discourse. The most frequent topoi were identified as the danger and threat topos, the burdening topos, the usefulness topos, and the humanitarianism topos. These topoi were found in all three grammatical modalities, most frequently everyday security practices. The intertextuality and interdiscursivity of utterances made within the discourse were discussed and evidence of recontextualization was present. As this dissertation analyses one discursive strategy, namely argumentations, a suggestion for future research is provided which proposes future research should analyse other discursive strategies and linguistic devices used in EU cybersecurity discourse.

description: We predict a bistability in the photon emission from a solid-state single-atom laser comprising a microwave cavity coupled to a voltage-biased double quantum dot. To demonstrate that the single-atom laser is bistable, we evaluate the photon emission statistics and show that the distribution takes the shape of a tilted ellipse. The switching rates of the bistability can be extracted from the electrical current and the shot noise in the quantum dots. This provides a means to control the photon emission statistics by modulating the electronic transport in the quantum dots. Our prediction is robust against moderate electronic decoherence and dephasing and is important for current efforts to realize single-atom lasers with gate-defined quantum dots as the gain medium.

description: Exoplanets in extremely close-in orbits are immersed in a local interplanetary medium (i.e., the stellar wind) much denser than the local conditions encountered around the solar system planets. The environment surrounding these exoplanets also differs in terms of dynamics (slower stellar winds, but higher Keplerian velocities) and ambient magnetic fields (likely higher for host stars more active than the Sun). Here, we quantitatively investigate the nature of the interplanetary media surrounding the hot Jupiters HD46375b, HD73256b, HD102195b, HD130322b, HD179949b. We simulate the three-dimensional winds of their host stars, in which we directly incorporate their observed surface magnetic fields. With that, we derive mass-loss rates (1.9 to 8.0 $\times 10^{-13} M_{\odot}$/yr) and the wind properties at the position of the hot-Jupiters' orbits (temperature, velocity, magnetic field intensity and pressure). We show that these exoplanets' orbits are super-magnetosonic, indicating that bow shocks are formed surrounding these planets. Assuming planetary magnetic fields similar to Jupiter's, we estimate planetary magnetospheric sizes of 4.1 to 5.6 planetary radii. We also derive the exoplanetary radio emission released in the dissipation of the stellar wind energy. We find radio fluxes ranging from 0.02 to 0.13 mJy, which are challenging to be observed with present-day technology, but could be detectable with future higher sensitivity arrays (e.g., SKA). Radio emission from systems having closer hot-Jupiters, such as from tau Boo b or HD189733b, or from nearby planetary systems orbiting young stars, are likely to have higher radio fluxes, presenting better prospects for detecting exoplanetary radio emission.

CFO Age and Real Earnings Management

description: This study examines the relationship between chief financial officer (CFO) age and real earnings management. Real earnings management is proxied by abnormal operating cash flows, abnormal production costs and abnormal discretionary expenses. Based on the extant literature, I develop two competing hypotheses in relation to CFO age and real earnings management. Using a sample of publicly listed US companies over the period from 2007 to 2018, I find a significant positive relationship between CFO age and real earnings management, implying that younger (older) CFOs engage less (more) in real earnings management. I also find that the negative relationship between younger CFO and real earnings management is more pronounced in the presence of younger CEO, CEO-chair separation and higher level of institutional ownership. Findings from the empirical analysis remain robust across alternative metrics of CFO age and real earnings management. Using two-stage least squares estimation, I show that the documented finding is not subject to the endogeneity problem. Overall, this study contributes to corporate governance literature and earnings management literature by identifying a robust relationship between CFO age and real earnings management.
Faster quantum searching with almost arbitrary operators

description: Grover search algorithm drives a quantum system from an initial state to a desired final state by using selective phase inversions of these two states. In (1), we studied a generalization of Grover algorithm which relaxes the assumption of the efficient implementation of the selective phase inversion of the initial state, also known as diffusion operator. This assumption is known to become a serious handicap in cases of physical interest (2,3,4,5). Our general search algorithm works with almost arbitrary diffusion operator with only restriction of having the initial state as one of its eigenstates. The price that we pay for using arbitrary operator is an increase in the number of oracle queries by a factor of order of B, where B is a characteristic of the eigenspectrum of diffusion operator and it can be large in some situations. Here we show that by using quantum fourier transform, we can regain the optimal query complexity of Grover algorithm without losing the freedom of using arbitrary diffusion operators for quantum searching. However, the total number of operators required by algorithm is still order of B times more than that of Grover algorithm. So our algorithm offers advantage only if oracle operator is computationally more expensive than diffusion operator, which is true in most search problems.
An Investigation of Social Belongingness as a Predictor of Physiological and Psychological Responses to Exam Stress

description: Social belongingness is a fundamental human need associated with a host of positive physiological and psychological health outcomes. Academic stress is a frequent and major stressor for undergraduate students that can negatively impact students’ physical and psychological well-being. Could social belongingness buffer the negative psychological and physical effects of exam stress within college students? The goal of the present study was to investigate whether social belongingness attenuated physiological (i.e., salivary cortisol, interleukin-6 [IL-6]) and psychological responses to exam stress. Participants (N=52) completed two study sessions: one during a week they did not have any exams (baseline), and one the day of a stressful exam. During their baseline session, participants completed a battery of questionnaires assessing their baseline levels of stress and social belongingness, and provided saliva and blood spot samples to measure salivary cortisol and IL-6. During the exam stress session, participants again completed a measure of psychological stress, and provided saliva and blood spot samples. Results showed significant increases in perceived stress during the exam stress session compared to the baseline session. However, levels of cortisol and IL-6 during baseline and exam stress sessions were not significantly different. Belongingness did not predict physiological or psychological stress reactivity, but did predict lower levels of psychological stress at both baseline and stress sessions. Results of the present study suggest that belongingness may protect against general stress levels. Findings can be used to create and implement interventions to reduce academic stress in undergraduate students.

description: Collaborative partnerships between educators and families in early childhood education and care (ECEC) settings are proven to provide positive outcomes for children and reflect quality in educational service provision. However, while the significance of these collaborative partnerships has been evidenced, actualisation of collaborative partnerships in practice remains an enigma. Currently, a mismatch exists between policy discourse and field practices, perpetuating a disconnect in expectations and outcomes of collaborative partnerships for stakeholders. Existing research points to the need to better understand how collaborative partnerships are enacted, maintained, and sustained by educators and families. This research study sought to explore how educators and families perceived and experienced successful collaborative partnerships in ECEC settings, rated as Exceeding Australia’s National Quality Standards. Three ECEC services participated in a poststructural case study. Data collection included observations of daily routines with educators and family members, followed by semi-structured interviews. Situational Analysis cartographic mapping provided a simultaneous data collection and analysis method that complemented the poststructural research design to reveal the multiple truths of participants. Findings revealed that high-quality collaborative partnerships were positively influenced by educator and family values being strongly aligned with the service philosophy, and that ECEC spaces were a mediating factor in collaborative partnerships. The study’s insights extend on existing literature to offer new understandings of how key components and inclusions of collaborative partnerships are enacted in practice and provide further clarity for the ECEC field in terms of translating and actualising research insights into practice. In addition to these ECEC findings, the study offers an innovative methodological contribution through the employment of a poststructural case study approach, the novel application of situational analysis, and extending the application of cartographic mapping.
