description: We propose a cooling scheme to prepare stationary entanglement of neutral atoms in the Rydberg blockade regime by combination of periodically collective laser pumping and dissipation. In each cycle, the controlled unitary dynamics process can selectively pump atoms away from the non-target state while maintaining the target state unchanged. The subsequent dissipative process redistributes the populations of ground states through the engineered spontaneous emission. After a number of cycles, the system will be eventually stabilized into the desired steady state independent of the initial state. This protocol does not rely on coherent addressing of individual neutral atoms or fine control of Rydberg interaction intensity, which can in principle greatly improve the feasibility of experiments in related fields.

description: Quantum phase estimation algorithm has been successfully adapted as a sub frame of many other algorithms applied to a wide variety of applications in different fields. However, the requirement of a good approximate eigenvector given as an input to the algorithm hinders the application of the algorithm to the problems where we do not have any prior knowledge about the eigenvector. In this paper, we show that the principal eigenvalue of an irreducible non-negative operator can be determined by using an equal superposition initial state in the phase estimation algorithm. This removes the necessity of the existence of an initial good approximate eigenvector. Moreover, we show that the success probability of the algorithm is related to the closeness of the operator to a stochastic matrix. Therefore, we draw an estimate for the success probability by using the variance of the column sums of the operator. This provides a priori information which can be used to know the success probability of the algorithm beforehand for the non-negative matrices and apply the algorithm only in cases when the estimated probability reasonably high. Finally, we discuss the possible applications and show the results for random symmetric matrices and 3-local Hamiltonians with non-negative off-diagonal elements.

Optimizing emergency stroke transport strategies using physiological models
Creators: name: Paydarfar, Daniel A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Background and Purpose: The criteria for choosing between Drip and Ship (DNS) and Mothership (MS) transport strategies in emergency stroke care is widely debated. While existing data-driven probability models can inform transport decision-making at an epidemiological level, we propose a novel mathematical, physiologically derived framework that provides insight into how patient characteristics underlying infarct core growth influence these decisions. 

Methods: We represent the physiology of time-dependent infarct core growth within an ischemic penumbra as an exponential function with consideration to rate-determining collateral blood flow. Monte Carlo methods generate distributions of infarct core volumes, which are translated to distributions of 90-day modified Rankin Scores. We apply the model to a stroke network that serves the rural Bastrop County and urban Travis County by simulating transport strategies from thousands of potential patient pickup locations. In every pickup location, the simulation yields a distribution of outcomes corresponding to each transport strategy. A two-sample Kolmogorov-Smirnov test and student t-test determine which transport strategy provides a significantly better probability of a good outcome for a given pickup location in each respective county (P < 0.01).  

Results: In Travis County, DNS provides significantly better probabilities of a good outcome in 24.0% of the pickup locations, while 59.8% favor MS. In Bastrop County, 11.3% of the pickup locations favor DNS, while only 7.1% favor MS. The remaining pickup locations in each county are not statistically significant in either direction. We also reveal how differing rates of infarct core growth, the application of bypass policies, and the use of large vessel occlusion field tests impact these results.  

Conclusions: Modeling stroke physiology enables the use of clinically relevant metrics for determining comparative significance between DNS and MS in a given geography. This formalism can help understand and inform emergency medical service transport decision-making, as well as regional bypass policies.
Comment on "first accuracy evaluation of NIST-F2"

description: We discuss the treatment of the systematic frequency shifts due to microwave lensing and distributed cavity phase in "First accuracy evaluation of NIST-F2" 2014 Metrologia 51 174-182. We explain that the microwave lensing frequency shift is generally non-zero and finite in the limit of no applied microwave field. This systematic error was incorrectly treated and we find that it contributes a significant frequency offset. Accounting for this shift implies that the measured microwave amplitude dependence (e.g due to microwave leakage) is comparable to the total reported inaccuracy. We also discuss the importance of vertically aligning the fountain perpendicular to the axis of the cavity feeds, when the cavity has only two independent feeds. Finally, we note that background gas collisions have a different behavior for cold clock atoms than for clock atoms at room-temperature, and therefore room temperature measurements do not directly apply to laser-cooled clocks.

Morphometrics as a robust tool for disambiguation in plant taxonomy: the case of Lactuca livida, a commonly accepted but never delimited taxon

description: An important goal of taxonomy is to clarify the identity of ambiguous taxa. Since lineage divergence usually involves ecological shifts that are associated with plant morphology, we propose that searching for fixed, non-overlapping morphological characters and specific associations of features should be the first task in disambiguation. We applied this idea in an analysis of the taxonomic identity of Lactuca livida, an Iberian endemic relative of L. virosa that, despite an extremely imprecise delimitation, is usually recognized in standard floras and germplasm banks. We analysed 24 possible diagnostic characters across the Iberian Peninsula, drawn from related taxonomic literature. No discontinuities in frequency variability distribution characters were found, even in two bimodal quantitative characters: leaf lobation and number of florets per capitulum. There were no notable patterns of association among characters, and the PCA/PCoA score plots did not show any distinctive groupings. Leaf lobation followed a significant geographic pattern, but there was no effective segregation of leaf shapes. We conclude that the variability found is symplesiomorphic, as it is present throughout the Serriola group of Lactuca, to which L. virosa belongs. The analyses, together with previous biological knowledge, indicates that Lactuca livida should be considered a synonym of L. virosa.

description: The thesis question is: "How did two 'high resource' school districts respond to federal free and reduced-price meal distribution during COVID-19 school closures?" This thesis explores how COVID-19 has impacted children's access to school provided, free and reduced-price meals during school closures. In comparing two high-resource school districts, we can analyze the differences in resource utilization at the district-level between two districts with similar amount of resources/funding and aim to understand how these districts differ in emergency meal provision strategies from an equity standpoint.

Maxwell field with gauge fixing term in de Sitter space: exact solution and stress tensor

Year: 2022

description: The Maxwell field with a general gauge fixing (GF) term is nontrivial, not only the longitudinal and temporal modes are mixed up in the field equations, but also unwanted consequences might arise from the GF term. We derive the complete set of solutions in de Sitter space, and implement the covariant canonical quantization which restricts the residual gauge transformation down to a quantum residual gauge transformation. Then, in the Gupta-Bleuler (GB) physical state, we calculate the stress tensor which is amazingly independent of the gauge fixing constant and is also invariant under the quantum residual gauge transformation. The transverse components are simply the same as those in the Minkowski spacetime, and the transverse vacuum stress tensor has only one UV divergent term ($\propto k^4$), which becomes zero by the 0th-order adiabatic regularization. The longitudinal-temporal stress tensor in the GB state is zero due to a cancelation between the longitudinal and temporal parts. More interesting is the stress tensor of the GF term. Its particle contribution is zero due to the cancelation in the GB state, and its vacuum contribution is twice that of a minimally-coupling massless scalar field, containing $k^4$ and $k^2$ divergences. After the 2nd-order adiabatic regularization, the GF vacuum stress tensor becomes zero too, so that there is no need to introduce a ghost field, and the zero GF vacuum stress tensor can not be a possible candidate for the cosmological constant. Thus, all the physics predicted by the Maxwell field with the GF term will be the same as that without the GF term. We also carry out analogous calculation in the Minkowski spacetime, and the stress tensor is similar to, but simpler than that in de Sitter space.

description: Land values have tended to increase at a substantially more rapid rate than the general level of prices in recent years. There is a growing body of evidence that this is occurring due, in part, to factors other than agricultural opportunity costs, size of parcel, improvements and other factors historically related to land values (Bishop, Bryant, Pasour). Some other factors influencing rural land values seem to include urbanization, investment or speculation, and increasing wealth or incomes. Additional information on the determinants of land values is needed if these phenomena are to be more completely understood. This paper reports on a study of the relationships of socio-economic characteristic of land owners (buyers and sellers) and rural land values.

description: Hemp (Cannabis sativa) is a well-known crop with a great potential to produce fibers without being excessively water and nutrient demanding. Moreover, hemp can be considered a viable and sustainable alternative to reach a cleaner production in the garment industry. Accurate information on fiber traits will enhance the exploitation of hemp in textile and biofuel industry. The aim of this work was to investigate the cyto-histological characteristics of hemp primary and secondary fibers through semi-thin sections and a light microscopy approach. To this purpose, we cultivated in open field a dioecious hemp variety under two different sowing densities and two different fertilization regimes. We confirmed the prominent role of sex in influencing all the analyzed traits; moreover, we found the possibility to mitigate it by changing the sowing density and the fertilization regime. In particular, the cell wall thickening in primary fibers was reduced in female plants by high fertilization. In male plants, combining high fertilization and low density, secondary fibers development is deeply increased. Cell area, in both plant sexes, was reduced by high fertilization. Operating on these simple agronomic aspects could thus result in the desired amount of fibers/lignin, depending on the final purpose of hemp cultivation.

description: We present Atacama Large Millimeter/submillimeter Array observations at $\approx100$ GHz with $0.05$ arcsec (3 pc) resolution of the kiloparsec-scale jet seen in the nearby Seyfert galaxy NGC 1068, and we report the presence of parsec-scale blobs at the head of the jet. The combination of the detected radio flux ($\approx0.8$ mJy), spectral index ($\approx0.5$), and the blob size ($\approx10$ pc) suggests a strong magnetic field of $B\approx240\,μ$G. Such a strong magnetic field most likely implies magnetic field amplification by streaming cosmic rays. The estimated cosmic-ray power by the jet may exceed the limit set by the star formation activity in this galaxy. This result suggests that even modest-power jets can increase the galactic cosmic-ray content while propagating through the galactic bulge.

description: A class of models of dark sectors consider new very weak interaction between the ordinary and dark matter transmitted by U'(1) gauge bosons A' (dark photons) mixing with our photons. If such A's exist, they could be searched for in a light-shining-through-a-wall experiment with a high energy electron beam from the CERN SPS. The proposed search scheme suggests detection of the e+e- pairs produced in the A' -> e+e- decay with a very small opening angle. Coordinate chambers based on the thin-wall drift tubes with a minimal material budget and a two-hit resolution for e+ and e- tracks separated by more than 0.5 mm are considered as an option for detecting such pairs.
Student Perceptions of Racial Microaggressions
Creators: name: Wainwright, Anna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: In order to begin to comprehend the extent of racism and inequality today, scholars must analyze the various aspects of racism that exist in contemporary society. Not simply institutional forces, but also individual level practices and acts at the micro-level that perpetuate racist structures. Racial microaggressions (RM) are part of these micro-level forces. Racial microaggressions can be defined as daily interactions that target a particular racial or ethnic group and communicate hostile or negative insults to a targeted group (Pierce 1969). In order to better understand the phenomenon of RM, I conducted a survey on undergraduate students at the University of North Carolina at Chapel Hill. Looking particularly at RM against black students from a white aggressor, I analyze various perceptions of RM scenarios from a number of key demographics. This study replicates the work of Tao and colleagues (2017) and expands the scope of their study. I find that negative emotional reactions and critiques of cultural competency become more likely when individuals are presented with RM scenarios while positive emotional reactions and feelings of neutrality become less common. I found inconsistent results when looking at how demographics affect this relationship. Variables such as sexual orientation and political ideology produced more significant results compared to that of race, gender, high school minority enrollment and year in school.

description: Anthemis parlatoreana was collected in the north west coast of Sicily. Fresh and dried aerial parts were subjected to distillation procedure for the extraction and isolation of essential oils. In both fresh and dried samples, the most abundant chemical classes were ketones and esters, represented to a greater extent by β-thujone and β-artemisia acetate, respectively. In dried vegetable material, a high content of α-pinene and δ3-carene was also registered. Aqueous, methanol and ethyl acetate extracts of aerial parts were also investigated in terms of polyphenolic content and antioxidant potential. All the extracts tested showed a quite different quali-quantitative profile and in terms of chemical classes, most of compounds belonged to the hydroxycinnamic class (15 compounds) followed by flavonoid one (11 compounds); the rest was comprised of 2 sequiterpenoids, 2 organic acids and 1 hydroxybenzoic acid derivative. Further, the dried methanolic followed by the dried aqueous extracts revealed the best quenching ability, whereas concerning iron chelating capacity, although all of them showed a marked capacity to disrupt or inhibit the formation of iron (II)-Ferrozine complex, a slight difference was observed between the dried and the fresh ones, since the former have a slightly higher chelating power than the latter.
The Paradox of Gender Inequality between Japan and the Philippines: Issue Framing in Post-War Women’s Movements

description: Despite Japan’s strong economic prosperity and worldwide influence, it has a relatively low level of gender egalitarianism. The Philippines, meanwhile, while still a developing country, has a higher level of gender equality than Japan. This thesis investigates how social movements in the post-World War II period – specifically the New Life Movement and Women’s Liberation Movement in Japan and the Filipino Women’s Movement in the Philippines – may help explain the economic development – gender equality paradox between Japan and the Philippines. Through an adapted critical frame theory framework and an examination of both secondary and statistical sources, I analyzed the actors, issue frames, proposed social problem and solution, goals, methods, and outcomes of each movement. I found that the issue frame utilized by each movement was connected to its ability to bring about social and legislative change, especially each issue frame’s broadness of scope, adoption or rejection of traditional gender roles, and inclusion or exclusion of government support. Thus, the issue frames utilized by post-war social movements may help explain the economic development – gender equality paradox between Japan and the Philippines. The findings of this thesis are relevant to future studies of social and women’s movements and how issue framing affects movement success.

description: Living creatures exhibit a remarkable diversity of locomotion mechanisms, evolving structures specialized for interacting with their environment. In the vast majority of cases, locomotor behaviours such as flying, crawling and running are orchestrated by nervous systems. Surprisingly, microorganisms can enact analogous movement gaits for swimming using multiple, fast-moving cellular protrusions called cilia and flagella. Here, I demonstrate intermittency, reversible rhythmogenesis and gait mechanosensitivity in algal flagella, to reveal the active nature of locomotor patterning. In addition to maintaining free-swimming gaits, I show that the algal flagellar apparatus functions as a central pattern generator that encodes the beating of each flagellum in a network in a distinguishable manner. The latter provides a novel symmetry-breaking mechanism for cell reorientation. These findings imply that the capacity to generate and coordinate complex locomotor patterns does not require neural circuitry but rather the minimal ingredients are present in simple unicellular organisms.This article is part of the Theo Murphy meeting ‘Unity and diversity of ciliary systems in locomotion and transport’.

Health During COVID-19: Racial and Ethnic Disparities in Healthcare Access and Resources Through Provider Perspectives
Creators: name: Dev, Kristina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: The COVID-19 pandemic has highlighted various social inequalities, including racial health disparities. People of color in the United States are diagnosed with and die from the coronavirus at higher rates than White individuals, and face additional barriers in accessing treatment and other forms of healthcare. Factors that place people of color at a higher risk for the coronavirus are widespread and systemic, and lead to the poorer coronavirus outcomes seen within communities of color. This study reveals how people of color are navigating the COVID-19 pandemic, and the role of community social workers and healthcare workers in providing access to health-determining resources and healthcare. Interviews with social workers and healthcare providers answer how barriers to healthcare are navigated during the pandemic, what the challenges of serving these populations are, and how cultural and language differences are overcome to improve access to healthcare resources and treatment. Additional interview topics include how undocumented and uninsured individuals are accessing coronavirus testing and treatment, and how adequate and appropriate care is ensured for these individuals. This study exhibits the importance of access to healthcare in shaping disease outcomes, and the relationship between systemic racism and public health. Understanding of these factors provides insight to how the needs of communities of color can be better addressed, and what steps must be taken to address health disparities.

description: The ‘mass ratio’ hypothesis states that ecosystem functioning is driven by the functional traits of the most dominant species in communities. Thus, we aimed to evaluate (i) How topographical conditions and stand age determine changes in tree community composition, richness, abundance and carbon dominant (CD) species, and (ii) Assess whether community-weighted mean of functional trait values of CD species explain aboveground carbon (AGC) stock. We used community-weighted mean of wood density and maximum stem diameter to evaluate the effect of functional dominance in AGC stock. We found that different topographic conditions and stand age change community composition, richness, abundance and CD species along the late-secondary stage. Our results showed that functional trait values of CD species determine AGC stock. Thus, the proportion of CD species was shaped by topography and stand age, whereas carbon stock by the dominant species’ functional traits (wood density and diameter). This study advances our understanding of the mechanisms that drive carbon stock in tropical forests and supports the ‘mass ratio’ hypothesis. We emphasize the relevance of the trait-based approach to understand forest functioning and trait functional composition and taxonomic identity for carbon storage, recovery and increase in secondary Atlantic Forests.

description: In this work we propose a novel approach to integrate the Lane-Emden equations for relativistic anisotropic polytropes. We take advantage of the fact that Gravitational Decoupling allows to decrease the number of degrees of freedom once a well known solution of the Einstein field equations is provided as a seed so after demanding the polytropic equation for the radial pressure the system is automatically closed. The approach not only allows to extend both isotropic or anisotropic known solutions but simplifies the computation of the Tolman mass whenever the Minimal Geometric Deformation is considered given that the $g_{tt}$ component of the metric remains unchanged. We illustrate how the the method works by analyzing the solutions obtained from Tolman IV, Durgapal IV and Wymann IIa isotropic systems as a seed for the integration.

Creators: name: Gellion, Stephen J.
Publisher: name: Central Queensland University
Year: 2018
Subjects: Educational planning and teaching practice

description: Teachers undertake planning activities at an individual, collegial and whole school level. Existing research into teacher planning has mainly focused on collegial and whole school planning. However, there is limited research into the use of teacher planning time provided to teachers in the Australian secondary school context. This research explored teacher perceptions and experiences of planning time using a sequential mixed method methodology.

description: To investigate the effects of environment in the quenching phase, we study the empirical relations for green valley (GV) galaxies between overdensity and other physical properties (i.e., effective radius $r_{\rm e}$, Sérsic indices $n$, and specific star formation rate sSFR). Based on five 3D-{\it HST}/CANDELS fields, we construct a large sample of 2126 massive ($M_{\star} > 10^{10} M_{\sun}$) GV galaxies at $0.5

description: We study a simple one-dimensional coupled wave-heat system and obtain a sharp estimate for the rate of energy decay of classical solutions. Our approach is based on the asymptotic theory of $C_0$-semigroups and in particular on a result due to Borichev and Tomilov (Math. Ann., 2010), which reduces the problem of estimating the rate of energy decay to finding a growth bound for the resolvent of the semigroup generator. This technique not only leads to an optimal result, it is also simpler than the methods used by other authors in similar situations.

Supplementary methods and figures from Synchrony and symmetry-breaking in active flagellar coordination

description: Living creatures exhibit a remarkable diversity of locomotion mechanisms, evolving structures specialized for interacting with their environment. In the vast majority of cases, locomotor behaviours such as flying, crawling and running are orchestrated by nervous systems. Surprisingly, microorganisms can enact analogous movement gaits for swimming using multiple, fast-moving cellular protrusions called cilia and flagella. Here, I demonstrate intermittency, reversible rhythmogenesis and gait mechanosensitivity in algal flagella, to reveal the active nature of locomotor patterning. In addition to maintaining free-swimming gaits, I show that the algal flagellar apparatus functions as a central pattern generator which encodes the beating of each flagellum in a network in a distinguishable manner. The latter provides a novel symmetry-breaking mechanism for cell reorientation. These findings imply that the capacity to generate and coordinate complex locomotor patterns does not require neural circuitry but rather the minimal ingredients are present in simple unicellular organisms.This article is part of the Theo Murphy meeting ‘Unity and diversity of ciliary systems in locomotion and transport’.
Rejection Sensitivity and Female Adolescent Depression: The Impact of Social Support
Creators: name: Baresich, Kayla
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Background: Adolescence is a time of rapid physical maturation, psychological and cognitive development amidst the backdrop of a constantly evolving social landscape. It is likely a combination of these many factors that puts girls at a three-fold greater risk of developing mood disorders compared to their male peers. Rejection sensitivity has been identified as a powerful predictor of depression and may be particularly relevant to female adolescents due to the increasingly high importance of social relationships to girls in this developmental stage. In the current study, the impact of social support from family and friends was examined as a positive influence on reducing rejection sensitivity, and thus, symptoms of depression in adolescent girls. 
Objective: The objective of the current study was to determine whether higher rejection sensitivity and lack of perceived social support would independently predict depression and whether a lack of perceived social support from family, rather than friends, would be a stronger predictor of depression. Furthermore, family social support was expected to buffer the effects of rejection sensitivity on girls’ risk for depression. 
Method: 56 adolescent girls (mean age = 12.46, SD = .93) completed self-reported measures of rejection sensitivity (Child’s Rejection Sensitivity Questionnaire), social support (Multidimensional Scale of Perceived Social Support), and depressive symptoms (Mood and Feelings Questionnaire). Factor analyses were utilized to identify distinct constructs of depression (somatic, self-hatred, suicidal/hopeless) assessed using the Mood and Feelings Questionnaire. Exploratory mediation analyses examined social support as a mediator in the relationship between rejection sensitivity and depression symptoms.
Results: Rejection sensitivity significantly predicted depression (p < .001), and social support from both family and friends was associated with reduced depression symptoms assessed over the total MFQ (p = .001, p = .007). Furthermore, social support from family mediated the effects of rejection sensitivity on somatic symptoms of depression, but not symptoms associated with self-hatred or suicidality/hopelessness.
Conclusions: Social support, particularly from family, was protective against the deleterious effects of rejection sensitivity on depression symptoms. These findings highlight the importance of considering social factors in the risk of adolescent depression and the critical buffering influence of emotional support.
Asymptotic work statistics of periodically driven Ising chains

description: We study the work statistics of a periodically-driven integrable closed quantum system, addressing in particular the role played by the presence of a quantum critical point. Taking the example of a one-dimensional transverse Ising model in the presence of a spatially homogeneous but periodically time-varying transverse field of frequency $ω_0$, we arrive at the characteristic cumulant generating function $G(u)$, which is then used to calculate the work distribution function $P(W)$. By applying the Floquet theory we show that, in the infinite time limit, $P(W)$ converges, starting from the initial ground state, towards an asymptotic steady state value whose small-$W$ behaviour depends only on the properties of the small-wave-vector modes and on a few important ingredients: the time-averaged value of the transverse field, $h_0$, the initial transverse field, $h_{\rm i}$, and the equilibrium quantum critical point $h_c$, which we find to generate a sequence of non-equilibrium critical points $h_{*l}=h_c+lω_0/2$, with $l$ integer. When $h_{\rm i}\neq h_c$, we find a "universal" edge singularity in $P(W)$ at a threshold value of $W_{\rm th}=2|h_{\rm i}-h_c|$ which is entirely determined by $h_{\rm i}$. The form of that singularity --- Dirac delta derivative or square root --- depends on $h_0$ being or not at a non-equilibrium critical point $h_{*l}$. On the contrary, when $h_{\rm i}=h_c$, $G(u)$ decays as a power-law for large $u$, leading to different types of edge singularity at $W_{\rm th}=0$. Generalizing our calculations to the case in which we initialize the system in a finite temperature density matrix, the irreversible entropy generated by the periodic driving is also shown to reach a steady state value in the infinite time limit.

description: We elucidate the intermediate of the macroscopic fluid model and the microscopic kinetic model by studying the Poisson algebraic structure of the one-dimensional Vlasov-Poisson system. The water-bag model helps formulating the hierarchy of sub-algebras, which interpolates the gap between the fluid and kinetic models. By analyzing the embedding of the sub-manifold of an intermediate hierarchy in a more microscopic hierarchy, we characterize the microscopic effect as the symmetry breaking pertinent to a macroscopic invariant.
