description: Zero modes are an essential part of topological field theories, but they are frequently also an obstacle to the explicit evaluation of the associated path integrals. In order to address this issue in the case of Ray-Singer Torsion, which appears in various topological gauge theories, we introduce a massive variant of the Ray-Singer Torsion which involves determinants of the twisted Laplacian with mass but without zero modes. This has the advantage of allowing one to explicitly keep track of the zero mode dependence of the theory. We establish a number of general properties of this massive Ray-Singer Torsion. For product manifolds $M=N \times S^1$ and mapping tori one is able to interpret the mass term as a flat $\mathbb{R}_{+}$ connection and one can represent the massive Ray-Singer Torsion as the path integral of a Schwarz type topological gauge theory. Using path integral techniques, with a judicious choice of an algebraic gauge fixing condition and a change of variables which leaves one with a free action, we can evaluate the torsion in closed form. We discuss a number of applications, including an explicit calculation of the Ray-Singer Torsion on $S^1$ for $G=PSL(2,R)$ and a path integral derivation of a generalisation of a formula of Fried for the torsion of finite order mapping tori.

description: Eye regression occurs across cave-dwelling populations of many species and is often coupled with a decrease or loss in eye function. Teleost fishes are among the few vertebrates to undergo widespread colonization of caves and often exhibit eye regression with blindness. Cave populations of the poeciliid fish Poecilia mexicana (cave molly) exhibit reduced—albeit functional—eyes, offering the opportunity to investigate partial eye regression. We sequenced eye transcriptomes of cave and surface populations of P. mexicana to identify differentially expressed genes that potentially underlie eye regression in cave mollies. We identified 29 significantly differentially expressed genes, 20 of which were directly related to light sensitivity, eye structure and visual signalling. Twenty-seven of these genes were downregulated in cave compared to surface populations. Functional enrichment analysis revealed eye-related gene ontologies that were under-represented in cave mollies. In addition, a set of co-expressed genes related to vision and circadian rhythm was correlated with habitat type (cave versus surface). Our study suggests that differential gene expression plays a key role in the beginning evolutionary stages of eye regression in P. mexicana, shedding further light on regressive evolution in cavefish.

description: Binary-driven-hypernovae (BdHNe) within the induced gravitational collapse (IGC) paradigm have been introduced to explain energetic ($E_{\rm iso}\gtrsim 10^{52}$~erg), long gamma-ray bursts (GRBs) associated with type Ic supernovae (SNe). The progenitor is a tight binary composed of a carbon-oxygen (CO) core and a neutron star (NS) companion, a subclass of the newly proposed "ultra-stripped" binaries. The CO-NS short-period orbit causes the NS to accrete appriciable matter from the SN ejecta when the CO core collapses, ultimately causing it to collapse to a black hole (BH) and producing a GRB. These tight binaries evolve through the SN explosion very differently than compact binaries studied in population synthesis calculations. First, the hypercritical accretion onto the NS companion alters both the mass and momentum of the binary. Second, because the explosion timescale is on par with the orbital period, the mass ejection can not be assumed to be instantaneous. This dramatically affects the post-SN fate of the binary. Finally, the bow shock created as the accreting NS plows through the SN ejecta transfers angular momentum, braking the orbit. These systems remain bound even if a large fraction of the binary mass is lost in the explosion (well above the canonical 50\% limit), and even large kicks are unlikely to unbind the system. Indeed, BdHNe produce a new family of NS-BH binaries unaccounted for in current population synthesis analyses and, although they may be rare, the fact that nearly 100\% remain bound implies they may play an important role in the compact merger rate, important for gravitational waves (GWs) that, in turn, can produce a new class of ultrashort GRBs.

description: Historically, FU Orionis-type stars are low-mass, pre-main sequence stars. The members of this class experience powerful accretion outbursts and remain in an enhanced accretion state for decades or centuries. V1515 Cyg, a classical FUor, started brightening in the 1940s and reached its peak brightness in the late 1970s. Following a sudden decrease in brightness it stayed in a minimum state for a few months, then started a brightening for several years. We present results of our ground-based photometric monitoring complemented with optical/NIR spectroscopic monitoring. Our light curves show a long-term fading with strong variability on weekly and monthly time scales. The optical spectra show P Cygni profiles and broad blue-shifted absorption lines, common properties of FUors. However, V1515 Cyg lacks the P Cygni profile in the Ca II 8498 Å line, a part of the Ca infrared triplet (IRT), formed by an outflowing wind, suggesting that the absorbing gas in the wind is optically thin. The newly obtained near-infrared spectrum shows the strengthening of the CO bandhead and the FeH molecular band, indicating that the disk has become cooler since the last spectroscopic observation in 2015. The current luminosity of the accretion disk dropped from the peak value of 138 $L_{\odot}$ to about 45 $L_{\odot}$, suggesting that the long-term fading is also partly caused by the dropping of the accretion rate.

The Effects of the Introduction of Mass Transit on Residential Real Estate: A Case Study into the Charlotte Light Rail

description: In a car-centric world, many urban planners, economists, and city residents boast of the positive benefits of public transportation infrastructure and its ability to connect a city while making it greener and more mobile. Yet, numerous public transportation systems across the country exist which transport near-empty units across cities and above roads, such as the Detroit People Mover. This study attempts to quantify the Charlotte light rail’s (made up of the LYNX Blue Line and Blue Line Extension) impact on nearby residential real estate prices as a measure of success. In order to test the hypothesis that the Charlotte light rail positively impacted nearby real estate prices (within a half mile of the light rail line), I ran a difference-in-difference analysis made up of 25 years of home prices for 162 Charlotte neighborhoods from Zillow. The results of this linear, multivariate regression imply that the original LYNX Blue Line, which began operations in November of 2007, positively impacted nearby residential real estate prices both directly after operations began and later in its life. However, the LYNX Blue Line Extension, which connects directly to the original LYNX Blue Line in the center city of Charlotte, negatively impacted nearby residential real estate values since it began operation. While a plethora of factors may be responsible for the negative correlation between real estate prices and the LYNX Blue Line Extension, they are out of the scope of this study’s regression and analysis.

Here, we present the direct synthesis of two unique, atomically thin, multi-junction heterostructures by combining graphene with the monolayer transition-metal dichalocogenides: MoS2, MoSe2, and WSe2.The realization of MoS2-WSe2-Graphene and WSe2-MoSe2-Graphene heterostructures leads toresonant tunneling in an atomically thin stack with spectrally narrow room temperature negative differential resistance characteristics.

description: For the inflaton field we determine a new exact solution by using the Lie symmetry analysis. Specifically, we construct a second-order differential master equation for arbitrary scalar field potential by assuming that the spectral index for the density perturbations $n_{s}$ and the scalar to tensor ratio $r$ are related as $n_{s}-1=h\left( r\right) $. Function $h\left( r\right) $ is classified according to the admitted Lie symmetries for the master equation. The possible admitted Lie symmetries form the $A_{2}$, $A_{3,2}$, $A_{3,3}$ and $sl\left( 3,R\right) $ Lie algebras. The new inflationary solution is recovered by the Lie symmetries of the $A_{3,3}$ algebra. Scalar field potential is derived explicitly, while we compare the resulting spectral indices with the observations.

description: Double-lined eclipsing binaries allow the direct determination of masses and radii, which are key to test stellar models. With the launch of the TESS mission, many well-known eclipsing binaries have been observed at higher photometric precision, permitting the improvement of the absolute dimensions determinations. Using TESS data and newly-obtained spectroscopic observations, we aim at determining the masses and radii of the eccentric eclipsing binary systems V889 Aql and V402 Lac, together with their apsidal motion parameters. We modelled simultaneously radial velocity curves and times of eclipse for each target to precisely determine the orbital parameters of the systems, which we used to analyse the light curves and then obtain their absolute dimensions. We compared the obtained values with those predicted by theoretical models. We determined masses and radii of the components of both systems with relative uncertainties lower than 2%. V889 Aql is composed of two stars with masses $2.17\pm0.02$ M$_{\odot}$ and $2.13\pm0.01$ M$_{\odot}$ and radii $1.87\pm0.04$ R$_{\odot}$ and $1.85\pm0.04$ R$_{\odot}$. We found conclusive evidence of the presence of a third body orbiting V889 Aql with a period of 67 years. Based on the detected third light and the absence of signal in the spectra, we suggest that this third body could in turn be a binary composed by two $\sim$1.4 M$_{\odot}$ stars. V402 Lac is composed by two stars with masses $2.80\pm0.05$ M$_{\odot}$ and $2.78\pm0.05$ M$_{\odot}$ and radii $2.38\pm0.03$ R$_{\odot}$ and $2.36\pm0.03$ R$_{\odot}$. The times of minimum light are compatible with the presence of a third body for this system too, although its period is not yet fully sampled. In both cases we have found a good agreement between the observed apsidal motion rates and the model predictions.

On the Kinetic Theory of Subauroral Arcs

Year: 2022

description: We report on numerical and theoretical investigation of subauroral arcs within strong subauroral ion drifts (SAID)--STEVE and Picket Fence. Their explanation requires the specific suprathermal electron distribution and excitation of vibrational and electronic states of neutral species. We show that the ionospheric feedback in the strong SAID with low-density troughs with or without a so-called ionospheric valley generates intense, small-scale field-aligned currents and electric fields below the F2 peak. With these fields, we solved the Boltzmann kinetic equation for the distribution of electrons and power for excitation and ionization of neutral gas (the energy balance). The obtained suprathermal electron population and energy balance are just what is necessary for Picket Fence. Concerning STEVE, the kinetic theory predictions are in a good qualitative agreement with its basic features. Besides, the theory predicts that subauroral arcs might have the transient phase with typical aurora-like emissions that fade out afterwards.
Nano-diamonds in proto-planetary discs: Life on the edge

description: Nano-diamonds remain an intriguing component of the dust in the few sources where they have been observed in emission. This work focusses on the nano-diamonds observed in circumstellar discs and is an attempt to derive critical information about their possible sizes, compositions, and evolution using a recently-derived set of optical constants. The complex indices of refraction of nano-diamonds and their optical properties (the efficiency factors Qext, Qsca, Qabs, and Qpr) were used to determine their temperatures, lifetimes, and drift velocities as a function of their radii (0.5-100 nm), composition (surface hydrogenation and irradiated states), and distance from the central stars in circumstellar regions. The nano-diamond temperature profiles were determined for the stars HR 4049, Elias 1, and HD 97048 in the optically-thin limit. The results indicate that large nano-diamonds (a = 30 - 100 nm) are the hottest and therefore the least resistant in the inner disc regions (~ 10-50 AU), while small (a < 10 nm) fully-hydrogenated nano-diamonds remain significantly cooler in these same regions. We discuss these results within the context of nano-diamond formation in circumstellar discs. Large nano-diamonds, being the hottest, are most affected by the stellar radiation field, however, the effects of radiation pressure appear to be insufficient to move them out of harm's way. The nano-diamonds that best survive and therefore shine in the inner regions of proto-planetary discs are then seemingly small (a < 10 nm), hydrogenated, and close in size to pre-solar nano-diamonds (a ~ 1.4 nm). Nevertheless, it does not yet appear possible to reconcile their existence there with their seemingly short lifetimes in such regions.

This is taken as an excuse to describe convenient calculus in infinite dimensions which allows for short and transparent proofs of the main facts of the theory of manifolds of smooth mappings. Smooth manifolds of immersions, diffeomorphisms, and shapes, and weak Riemannian metrics on them are treated, culminating in the surprising fact, that geodesic distance can vanish completely for them.

description: Thermal spin pumping constitutes a novel mechanism for generation of spin currents; however their weak intensity constitutes a major roadblock for its usefulness. We report a phenomenon that produces a huge spin current in the central region of a multilayer system, resulting in a giant spin Seebeck effect in a structure formed by repetition of ferromagnet/metal bilayers. The result is a consequence of the interconversion of magnon and electron spin currents at the multiple interfaces. This work opens the possibility to design thin film heterostructures that may boost the application of thermal spin currents in spintronics.

description: We construct new dispersive sum rules for the effective field theory of the standard model at mass dimension six. These spinning sum rules encode information about the spin of UV states: the sign of the IR Wilson coefficients carries a memory of the dominant spin in the UV completion. The sum rules are constructed for operators containing scalars and fermions, although we consider the dimension-six SMEFT exhaustively, outlining why equivalent relations do not hold for the remaining operators. As with any dimension-six dispersive argument, our conclusions are contingent on the absence of potential poles at infinity, so-called boundary terms, and we discuss in detail where these are expected to appear. There are a number of phenomenological applications of spinning sum rules, and as an example we explore the connection to the Peskin-Takeuchi parameters and, more generally, the set of oblique parameters in universal theories.

description: Humans and songbirds share the key trait of vocal learning, manifested in speech and song, respectively. Striking analogies between these behaviours include that both are acquired during developmental critical periods when the brain's ability for vocal learning peaks. Both behaviours show similarities in the overall architecture of their underlying brain areas, characterized by cortico-striato-thalamic loops and direct projections from cortical neurons onto brainstem motor neurons that control the vocal organs. These neural analogies extend to the molecular level, with certain song control regions sharing convergent transcriptional profiles with speech-related regions in the human brain. This evolutionary convergence offers an unprecedented opportunity to decipher the shared neurogenetic underpinnings of vocal learning. A key strength of the songbird model is that it allows for the delineation of activity-dependent transcriptional changes in the brain that are driven by learned vocal behaviour. To capitalize on this advantage, we used previously published datasets from our laboratory that correlate gene co-expression networks to features of learned vocalization within and after critical period closure to probe the functional relevance of genes implicated in language. We interrogate specific genes and cellular processes through converging lines of evidence: human-specific evolutionary changes, intelligence-related phenotypes and relevance to vocal learning gene co-expression in songbirds.This article is part of the theme issue ‘What can animal communication teach us about human language?’.
"In the World, but Not of It": Evangelism and Identity in the Orthodox Church in America during the Twentieth Century
Creators: name: Joshua Howard
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: This thesis argues that throughout the twentieth century, the Orthodox Church in America contemplated whether to turn inward and defend Orthodoxy from American and earthly influence or compromise with outside influences in order to spread the faith across the continent. Its commitment to preserve Orthodoxy from secularism led to periods of isolation after the Russian Revolution, but postwar ecumenism and liturgical revival led clergy to reclaim evangelism as a means to bringing others into the true church and combatting secularism. Nonetheless, the failure of ecumenism to convert the non-Orthodox complicated this narrative, leading parish priests and laity to pursue social conservatism to combat secularism. The first chapter will situate the OCA within the Russian Revolution, explaining the theological and social motivations for declaring autocephaly and separating from the Russian Orthodox Church in Moscow. The second chapter examines the OCA’s ecumenical relationships with Catholics and liberal Protestants as the OCA explored ecumenism as a means to spread Orthodoxy and stop the spread of secularism. The final chapter examines the OCA in the context of the rise of the Christian Right, arguing that while high clergy remained committed to ecumenism, some priests and laity viewed social conservatism as a better solution to secularism. In more recent years, the OCA has changed its relationship with American society and outside influence as laity and clergy become more involved in Orthodox and public discourse through digital platforms.

description: The search for planets orbiting other stars has recently expanded to include stars from galaxies outside the Milky Way. With the TESS and Gaia surveys, photometric and kinematic information can be combined to identify transiting planet candidates of extragalactic origin. Here, 1,080 low-luminosity red giant branch stars observed by Gaia and TESS with kinematics suggesting a high likelihood of extragalactic origin were searched for planet transits. Transit injection-recovery tests were performed to measure the sensitivity of the TESS data and completeness of the transit search. Injected signals of planets larger than Jupiter with orbital periods of 10 days or less were recovered in $\approx$44% of cases. Although no planet transits were detected in this sample, we find an upper limit on planet occurrence of 0.52% for hot Jupiters, consistent with previous studies of planet occurrence around similar host stars. As stars in the halo tend to be lower metallicity, and short period giant planet occurrence tends to be strongly correlated with stellar metallicity, we predict that relative to the Galactic disk population, a smaller fraction of halo stars will host planets detectable by transit surveys. Thus, applying the known planet occurrence trends to potential planet detection around halo stars, we predict $\gtrsim$7,000 stars must be searched with similar cadence and precision as the stars studied here before a detection of a planet of extragalactic origin is likely. This may be possible with future data releases from the TESS and Gaia missions.

Nuclear Receptor RORα Functions as a Transcriptional Activator of Alpha-1A-Adrenergic Receptor

description: Upregulation of the A subtype of alpha-1 adrenergic receptors (alpha-1A-ARs) is linked to cardioprotection during heart failure. Similarly, the transcription factor retinoid-related orphan receptor alpha (RORα) is upregulated to provide cardioprotection and has also been shown to contribute to adaptive changes in cardiomyocyte biology during heart failure. Though both alpha-1A-ARs and RORα contribute to cardioprotection and are both present in cardiomyocytes, a link between the two has not yet been found. In this paper, we show that RORα acts as a transcription factor regulating α1a levels in cardiomyocytes. We initially found through microarray analysis of heart tissue that α1A-ARs are expressed at significantly lower levels in the hearts of RORα knockout mice. Further analysis through quantitative reverse transcriptase polymerase chain reaction (qPCR) showed a decrease in alpha-1A-AR expression level in global and cardiomyocyte-specific RORα knockout mice. These results suggest that RORα might act as a transcriptional regulator of α1A, potentially linking the cardioprotective effects of α1a and RORα. Establishing a link between two important cardioprotective mechanisms may contribute to a better understanding of positive clinical outcomes in human heart failure, and may potentially open a new route for therapeutics to treat heart failure.

description: The accurate description of nuclear quantum effects, such as zero-point energy, is important for modeling a wide range of chemical and biological processes. Within the nuclear-electronic orbital (NEO) approach, such effects are incorporated in a computationally efficient way by treating electrons and select nuclei, typically protons, quantum mechanically with molecular orbital techniques. Herein, we implement and test a NEO coupled cluster method that explicitly includes the triple electron-proton excitations, where two electrons and one proton are excited simultaneously. Our calculations show that this NEO-CCSD(eep) method provides highly accurate proton densities and proton affinities, outperforming any previously studied NEO method. These examples highlight the importance of the triple electron-electron-proton excitations for an accurate description of nuclear quantum effects. Additionally, we also implement and test the second-order approximate coupled cluster with singles and doubles (NEO-CC2) method, as well as its scaled-opposite-spin (SOS) versions. The NEO-SOS$'$-CC2 method, which scales the electron-proton correlation energy as well as the opposite-spin and same-spin components of the electron-electron correlation energy, achieves nearly the same accuracy as the NEO-CCSD(eep) method for the properties studied. Because of its low computational cost, this method will enable a wide range of chemical and photochemical applications for large molecular systems. This work sets the stage for a wide range of developments and applications within the NEO framework.

description: Our recent re-analysis of the solar photospheric spectra with non-local thermodynamic equilibrium (non-LTE) models resulted in higher metal abundances compared to previous works. When applying the new chemical abundances to Standard Solar Model calculations, the new composition resolves the long-standing discrepancies with independent constraints on the solar structure from helioseismology. Critical to the determination of chemical abundances is the accuracy of the atomic data, specially the $f$-values, used in the radiative transfer models. Here we describe in detail the calculations of $f$-values for neutral oxygen and nitrogen used in our non-LTE models. Our calculations of $f$-values are based on a multi-method, multi-code approach and are the most detailed and extensive of its kind for the spectral lines of interest. We also report in this paper the details of extensive R-matrix calculation of photo-ionization cross sections for oxygen. Our calculation resulted in reliable $f$-values with well constrained uncertainties. We compare our results with previous theoretical and experimental determinations {of atomic data. We also quantify the influence of adopted photo-ionisation cross-sections on the spectroscopic estimate of the solar O abundance, using the data from different sources. We confirm that our 3D non-LTE value is robust and unaffected by the choice of photo-ionisation data, contrary to the recent claim made by Nahar.

description: Humans and songbirds share the key trait of vocal learning, manifested in speech and song, respectively. Striking analogies between these behaviours include that both are acquired during developmental critical periods when the brain's ability for vocal learning peaks. Both behaviours show similarities in the overall architecture of their underlying brain areas, characterized by cortico-striato-thalamic loops and direct projections from cortical neurons onto brainstem motor neurons that control the vocal organs. These neural analogies extend to the molecular level, with certain song control regions sharing convergent transcriptional profiles with speech-related regions in the human brain. This evolutionary convergence offers an unprecedented opportunity to decipher the shared neurogenetic underpinnings of vocal learning. A key strength of the songbird model is that it allows for the delineation of activity-dependent transcriptional changes in the brain that are driven by learned vocal behaviour. To capitalize on this advantage, we used previously published datasets from our laboratory and that correlate gene co-expression networks to features of learned vocalization within and after critical period closure to probe the functional relevance of genes implicated in language. We interrogate specific genes and cellular processes through converging lines of evidence: human-specific evolutionary changes, intelligence-related phenotypes and relevance to vocal learning gene co-expression in songbirds.This article is part of the theme issue ‘What can animal communication teach us about human language?’.

description: Tip of the red giant branch measurements based on Hubble Space Telescope and ground-based imaging have resulted in accurate distances to 29 galaxies in the nearby Centaurus A Group. All but two of the 29 galaxies lie in either of two thin planes roughly parallel with the supergalactic equator. The planes are only slightly tilted from the line-of-sight, leaving little ambiguity regarding the morphology of the structure. The planes have characteristic r.m.s. long axis dimensions of ~300 kpc and short axis dimensions of ~60 kpc, hence axial ratios ~0.2, and are separated in the short axis direction by 303 kpc.
