description: We studied the thermodynamic properties of the lithium perchlorate (LiClO4) + ethylene carbonate (EC) +water ternary system by using cell potential measurements. Thermodynamic properties reported were obtained using the electrochemical cell: Li-ISE|LiClO4(m)|ClO4-ISE in a variety of mixed solvent systems containing 0, 10, 20 and 30% mass fractions of ethylene carbonate in water + EC mixtures (wEC/wmixture% = 0, 10, 20 and 30) on the wide range of ionic strength from 0.0090 to 2.4900 mol.kg−1 at T = (298.2, 308.2 and 318.2) K. The obtained results were analysed using Extended Debye-Huckel equation and Pitzer model. The values of Pitzer ion-interaction parameters β(0), β(1) and Cϕ were used to drive the values of thermodynamic properties such as the excess Gibbs free energy, the solvent activity, mean activity coefficients, the osmotic coefficients and diffusion coefficients for this system.

description: Social media is known for its ability to spread information and raise awareness quickly, with online action often resulting in real-world changes. However, few have studied how effective social media can be when regarding the legal system, particularly when related to how social media can impact the overturning of wrongful convictions. With an estimated minimum of 46,000 people wrongfully incarcerated and only an estimated 1,000 attorneys donating their time to work on these cases, determining ways in which to provide support in overturning the charges for these individuals is vital. Five case studies of wrongfully incarcerated individuals were analyzed to compare the amount of social media interaction their case received, time the individual spent incarcerated, and characteristics that could have affected the level of bias seen on social media surrounding the individual. This study provides insight into how social media can help to promote true justice in the legal system, as well as what characteristics of wrongfully convicted individuals allow for successful framing of their cases on social media.

description: The light curves of 2768 stars with effective temperatures and surface gravities placing them near the gamma Doradus/delta Scuti instability region were observed as part of the Kepler Guest Observer program from Cycles 1 through 5. The light curves were analyzed in a uniform manner to search for gamma Doradus, delta Scuti, and hybrid star pulsations. The gamma Doradus, delta Scuti, and hybrid star pulsations extend asteroseismology to stars slightly more massive (1.4 to 2.5 solar masses) than our Sun. We find 207 gamma Doradus, 84 delta Scuti, and 32 hybrid candidate stars. Many of these stars are cooler than the red edge of the gamma Doradus instability strip as determined from ground-based observations made before Kepler. A few of our gamma Doradus candidate stars lie on the hot side of the ground-based gamma Doradus instability strip. The hybrid candidate stars cover the entire region between 6200 K and the blue edge of the ground-based delta Scuti instability strip. None of our candidate stars are hotter than the hot edge of the ground-based delta Scuti instability strip. Our discoveries, coupled with the work of others, shows that Kepler has discovered over 2000 gamma Doradus, delta Scuti, and hybrid star candidates in the 116 square degree Kepler field of view. We found relatively few variable stars fainter than magnitude 15, which may be because they are far enough away to lie between spiral arms in our Galaxy, where there would be fewer stars.

description: The inverse Kirkwood-Buff integrals were used to calculate the preferential solvation parameters of the natural polyphenolic compound chrysin in binary mixtures of ethanol (1) + water (2) and methanol (1) + water (2) as a function of their thermodynamic properties. At temperatures between 298.15 K and 318.15 K, chrysin is extremely sensitive to specific solvation effects; therefore, the negative values of δx1,3 were found in the water-rich range of 0 < x1 < 0.30 for methanol (1) + water (2) and 0 < x1 < 0.25 for ethanol (1) + water (2) which suggested that water (2) preferentially dissolves chrysin (3). In co-solvent-rich regions, the values of δx1,3 were positive, and the co-solvents preferentially dissolve chrysin (3). The solvation of drugs in water-rich mixtures is likely to be facilitated by hydrophobic hydration around aromatic rings or groups.
An ecological assessment of the non-indigenous isopod, Synidotea laticauda, in Delaware Bay
Creators: name: Boyd, Sean G.

Year: 2008

description: Synidotea laticauda is a non-indigenous marine isopod that has been documented in Delaware Bay since 1998. Due to its relatively resent arrive there is a general lack of scientific knowledge about the impact this isopod may have on local ecosystems. Extremely high seasonal abundances, documented over the past three years, suggest the potential for a strong impact. A presence-absence survey conducted during the summer of 2006 documented S. laticauda along portions of both the New Jersey and Delaware coasts of Delaware Bay and on several oyster seed beds within the bay. Isopods were only present in portions of the bay containing anthropogenic structures and salinities between 2 and 22. Synidotea laticauda were not observed along the Atlantic coasts of New Jersey or Delaware. Temperature-salinity challenges found that S. laticauda die quickly in fresh water but can survive in salinities of 30 and 35. The temperature-salinity challenges also found that S. laticauda survived in water temperatures typical for Delaware Bay. Although lethargic, isopods experienced very little mortality at 5° C; however, high mortality was experienced above 25° C. Regular monitoring of recently deployed (clean) and continuously deployed (fouled) cages in the Maurice River identified a preference for structures accumulating biological fouling. Several trophic interactions between S. laticauda and the biota of Delaware Bay were also identified in this study. Single-choice feeding trials identified predation on nine fauna and flora species and established S. laticauda as an omnivore capable of exploiting multiple food resources within the bay. Furthermore, gut content analyses of fish collected from the Maurice and Nantuxent Rivers indicate that a minimum of four predatory fish species consume S. laticauda, although it does not appear to be an important component of their diet. Collectively these findings indicate S. laticauda will persist in portions Delaware Bay but with a nominal ecological impact.

description: We present the ground state extension of the efficient quantum Monte Carlo algorithm for lattice fermions of arXiv:1411.0683. Based on continuous-time expansion of imaginary-time projection operator, the algorithm is free of systematic error and scales \emph{linearly} with projection time and interaction strength. Compared to the conventional quantum Monte Carlo methods for lattice fermions, this approach has greater flexibility and is easier to combine with powerful machinery such as histogram reweighting and extended ensemble simulation techniques. We discuss the implementation of the continuous-time projection in detail using the spinless $t-V$ model as an example and compare the numerical results with exact diagonalization, density-matrix-renormalization-group and infinite projected entangled-pair states calculations. Finally we use the method to study the fermionic quantum critical point of spinless fermions on a honeycomb lattice and confirm previous results concerning its critical exponents.

Sarcasm Used by Couples in the U.K. and U.S.: A Cultural Comparison
Creators: name: d'Oelsnitz, Anaïs
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Components of communication are key in romantic relationships and vary dependent on the dyad. A sense of humor facilitates playfulness; sarcasm use, while more ambiguous in meaning, might also serve to enhance relationship quality. For those who are less comfortable with direct communication (i.e., sharing their feelings), sarcasm might serve as a useful tool in sharing their thoughts without being too vulnerable. Such sharing might produce individual and dyadic benefits (i.e., laughter, closeness) or bolster fundamental aspects of relationship functioning (i.e., trust, comfort). Sarcasm is a particular communication strategy likely influenced by individual (i.e., gender) and situational factors (i.e., culture). The purpose of the current study was to investigate the effects of (a) culture (U.K. vs. U.S.), (b) gender (male vs. female), and the interaction between culture and gender on the use of sarcasm and humor, while considering openness to emotional expression as a potential explanation for these differences. Participants in romantic relationships completed an online survey examining their use of sarcasm, humor, and emotional expression with their partner (N=88). Moderated mediation analyses revealed a significant negative association between openness to express emotion and sarcasm use for individuals in romantic relationships. Existing literature on the use of sarcasm as an alternative for more direct and literal expression of emotions supports these findings. The findings also indicated that gender and culture interact in unexpected, complex ways to predict sarcasm use, noting the importance of openness to expression of emotion as part of the process. Furthermore, the current investigation demonstrated that the pattern of findings for sarcasm use did not generalize to humor more broadly in a dyadic context. Findings indicate the importance of understanding nuanced communication processes, particularly with regard to their use based on unique societal and cross-cultural factors.

description: The TOTEM experiment has made a precise measurement of the elastic proton-proton differential cross-section at the centre-of-mass energy sqrt(s) = 8 TeV based on a high-statistics data sample obtained with the beta* = 90 optics. Both the statistical and systematic uncertainties remain below 1%, except for the t-independent contribution from the overall normalisation. This unprecedented precision allows to exclude a purely exponential differential cross-section in the range of four-momentum transfer squared 0.027 < |t| < 0.2 GeV^2 with a significance greater than 7 sigma. Two extended parametrisations, with quadratic and cubic polynomials in the exponent, are shown to be well compatible with the data. Using them for the differential cross-section extrapolation to t = 0, and further applying the optical theorem, yields total cross-section estimates of (101.5 +- 2.1) mb and (101.9 +- 2.1) mb, respectively, in agreement with previous TOTEM measurements.

description: This review provides a broad overview of the studies and effects of nonlocal response in metallic nanostructures. In particular, we thoroughly present the nonlocal hydrodynamic model and the recently introduced generalized nonlocal optical response (GNOR) model. The influence of nonlocal response on plasmonic excitations is studied in key metallic geometries, such as spheres and dimers, and we derive new consequences due to the GNOR model. Finally, we propose several trajectories for future work on nonlocal response, including experimental setups that may unveil further effects of nonlocal response.

description: Graphene is an interesting material for spintronics, showing long spin relaxation lengths even at room temperature. For future spintronic devices it is important to understand the behavior of the spins and the limitations for spin transport in structures where the dimensions are smaller than the spin relaxation length. However, the study of spin injection and transport in graphene nanostructures is highly unexplored. Here we study the spin injection and relaxation in nanostructured graphene with dimensions smaller than the spin relaxation length. For graphene nanoislands, where the edge length to area ratio is much higher than for standard devices, we show that enhanced spin-flip processes at the edges do not seem to play a major role in the spin relaxation. On the other hand, contact induced spin relaxation has a much more dramatic effect for these low dimensional structures. By studying the nonlocal spin transport through a graphene quantum dot we observe that the obtained values for spin relaxation are dominated by the connecting graphene islands and not by the quantum dot itself. Using a simple model we argue that future nonlocal Hanle precession measurements can obtain a more significant value for the spin relaxation time for the quantum dot by using high spin polarization contacts in combination with low tunneling rates.
Examining the Effects of Inorganic Arsenic on Chromatin Accessibility and Genomic Response in Placental Cells Using ATAC-sequencing and RNA-sequencing

description: Exposure to environmental metals/metalloids, such as inorganic arsenic (iAs), is associated with a myriad of detrimental human health effects. Prenatal iAs exposure is associated with adverse health outcomes including pregnancy complications, and perinatal and later-onset effects in the offspring, but the precise mechanisms for these complications are understudied. We sought to examine the genomic and epigenetic contributions that may underlie the relationships among prenatal arsenic exposure, altered placental functions, and adverse health outcomes. To assess iAs’ effects on the placenta, we exposed JEG-3 placental choriocarcinoma cells to varying iAs concentrations for 24 hours. The Assay for Transposase-Accessible Chromatin with high-throughput sequencing (ATAC-seq) was then used to identify open regions of chromatin and RNA-sequencing (RNA-seq) was used to measure genome-wide iAs-induced changes in transcript levels. The results highlight that iAs modifies the chromatin structure differentially across the genome in a dose-dependent manner. Specifically, following exposure to iAs, 5297 chromatin regions were differentially accessible. The RNA sequencing data highlighted that 7485 genes displayed differential expression. Our findings provide mechanistic insight into the toxicity of iAs on human placental cells. These data are relevant to the known effects of prenatal exposure to iAs on fetal development and provide support for the Developmental Origins of Health and Human Diseases (DOHaD) hypothesis.

description: Supernova generated shock waves are responsible for most of the destruction of dust grains in the interstellar medium (ISM). Calculations of the dust destruction timescale have so far been carried out using plane parallel steady shocks, however that approximation breaks down when the destruction timescale becomes longer than that for the evolution of the supernova remnant (SNR) shock. In this paper we present new calculations of grain destruction in evolving, radiative SNRs. To facilitate comparison with the previous study by Jones et al. (1996), we adopt the same dust properties as in that paper. We find that the efficiencies of grain destruction are most divergent from those for a steady shock when the thermal history of a shocked gas parcel in the SNR differs significantly from that behind a steady shock. This occurs in shocks with velocities >~ 200 km/s for which the remnant is just beginning to go radiative. Assuming SNRs evolve in a warm phase dominated ISM, we find dust destruction timescales are increased by a factor of ~2 compared to those of Jones et al. (1996), who assumed a hot gas dominated ISM. Recent estimates of supernova rates and ISM mass lead to another factor of ~3 increase in the destruction timescales, resulting in a silicate grain destruction timescale of ~2-3 Gyr. These increases, while not able resolve the problem of the discrepant timescales for silicate grain destruction and creation, are an important step towards understanding the origin, and evolution of dust in the ISM.

description: Theoretical models predict that a population of Intermediate Mass Black Holes (IMBHs) of mass $M_\bullet \approx 10^{4-5} \, \mathrm{M_{\odot}}$ might form at high ($z > 10$) redshift by different processes. Such objects would represent the seeds out of which $z > 6$ Super-Massive Black Holes (SMBHs) grow. We numerically investigate the radiation-hydrodynamic evolution governing the growth of such seeds via accretion of primordial gas within their parent dark matter halo of virial temperature $T_{vir} \sim 10^4 \, \mathrm{K}$. We find that the accretion onto a Direct Collapse Black Hole (DCBH) of initial mass $M_0=10^5 \, \mathrm{M_{\odot}}$ occurs at an average rate $\dot{M}_{\bullet} \simeq 1.35 \, \dot{M}_{Edd} \simeq 0.1 \, \mathrm{M_{\odot} \, yr^{-1}}$, is intermittent (duty-cycle $ < 50\%$) and lasts $\approx 142 \, \mathrm{Myr}$; the system emits on average at super-Eddington luminosities, progressively becoming more luminous as the density of the inner mass shells, directly feeding the central object, increases. Finally, when $\approx 90\%$ of the gas mass has been accreted (in spite of an average super-Eddington emission) onto the black hole, whose final mass is $\sim 7 \times 10^6 \, \mathrm{M_{\odot}}$, the remaining gas is ejected from the halo due to a powerful radiation burst releasing a peak luminosity $L_{peak}\sim 3\times 10^{45} \, \mathrm{erg \, s^{-1}}$. The IMBH is Compton-thick during most of the evolution, reaching a column density $N_H \sim 10^{25} \, \mathrm{cm^{-2}}$ in the late stages of the simulation. We briefly discuss the observational implications of the model.

A Method for Computing the Off-Shell Four-point Tree Level Gluon Scattering Amplitude by the CHY Formalism
Creators: name: Stewart, Alexander
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: A method for computing the off-shell four-point tree level gluon scattering amplitude through the CHY formalism is proposed. First, we compute the relevant partial amplitude through standard procedures in quantum field theory. We then examine the previous work on computing gluon scattering amplitudes on-shell through the CHY formalism. We propose a modification to the CHY formalism to compute the off-shell four-point tree level gluon scattering amplitude and demonstrate how this modification results in an amplitude matching the off-shell quantum field theory computation in Feynman gauge.

Examining Mediators of the Relation Between Self-Concept Clarity and Body Dissatisfaction and Disordered Eating

description: Self-concept clarity, appearance contingent self-worth, and appearance-related social comparison have been shown to be correlated with body dissatisfaction and disordered eating. In the current study, we examine associations between these constructs and test four mediation models for appearance contingent self-worth and appearance-related social comparison as mediators of the relationship between self-concept clarity and body dissatisfaction and disordered eating. Using two waves of data collection, undergraduate females (N = 441 at Time 1; N = 237 at Time 2) completed online surveys of the study’s core constructs at points separated by approximately 14 months. Aligned with our hypotheses, we found significant correlations between self-concept clarity, appearance contingent self-worth, and appearance-related social comparison and eating disorder symptoms. Mediation analyses indicated that appearance contingent self-worth partially mediated the relationship between self-concept clarity and both body dissatisfaction and disordered eating. Additionally, appearance-related social comparison partially mediated the relationship between self-concept clarity and body dissatisfaction and fully mediated the relationship between self-concept clarity and disordered eating. Future research should examine if these findings extend to broader demographic groups. Future work could also extend the present models to test relationship contingent self-worth and other areas of social comparison, such as eating and exercise comparisons as mediators. Clinical implications include the potential for disordered eating interventions targeting a decrease in appearance contingent self-worth or appearance-related social comparisons.
Revisiting galactic rotation curves given a noncommutative-geometry background

description: It was shown earlier by Rahaman et al. that a noncommutative-geometry background can account for galactic rotation curves without the need for dark matter. The smearing effect that characterizes noncommutative geometry is described by means of a Gaussian distribution intended to replace the Dirac delta function. The purpose of this paper is two-fold: (1) to account for the galactic rotation curves in a more transparent and intuitively more appealing way by replacing the Gaussian function by the simpler Lorentzian distribution proposed by Nozari and Mehdipour and (2) to show that the smearing effect is both a necessary and sufficient condition for meeting the stability criterion.
