description: The growth and morphogenesis of cultured plant tissues can be improved by small amounts of some organic elements. In addition to being a natural source of carbon, organic additives may contain natural vitamins, phenols, fiber, hormones and also proteins. Hence, the physiological effects of apricot gum on the regeneration capacity and growth rate of three different plant species i.e. carrot (as a model plant), stevia (as an herbaceous plant), and grapevine (as a woody plant) were examined. The proliferated callus cultures of carrot and in vitro-derived microcuttings of stevia and grapevine were inoculated on their respective standardized proliferation media supplemented with 2.0-6.0 g/l apricot gum. The growth parameters of treated samples were measured and compared to gum-free medium. Earlier callus initiations with greater fresh weight, volume, as well as improved pigmentation were recorded in media fortified with apricot gum. The usefulness of gum application was also obvious in both stevia and grapevine with respect to better shoot multiplication and rooting parameters. Due to positive effects of apricot gum, longer vines with a higher number of lateral shoots, internodes and leaf area were achieved. Overall, the gum at the rate of 4.0 g/L was found to be a logical concentration with respect to encouraging response in all three species. Owing to promising results evolved in the present research, the application of gum in commercial tissue culture protocols is highly recommended. However, further studies are needed to exploit plant derived gums as an alternative carbon source in plant tissue culture media.

description: We present a definition of unsigned magnification in gravitational lensing valid on arbitrary convex normal neighborhoods of time oriented Lorentzian manifolds. This definition is a function defined at any two points along a null geodesic that lie in a convex normal neighborhood, and foregoes the usual notions of lens and source planes in gravitational lensing. Rather, it makes essential use of the van Vleck determinant, which we present via the exponential map, and Etherington's definition of luminosity distance for arbitrary spacetimes. We then specialize our definition to spacetimes, like Schwarzschild's, in which the lens is compact and isolated, and show that our magnification function is monotonically increasing along any geodesic contained within a convex normal neighborhood.

Raise Up: An Analysis of the Experience of Black Women Senior Level Administrators in College Athletics
Creators: name: Nottage, Gabrielle Nicole
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The purpose of this research is to explore the experience of NCAA Division I Black female senior-level administrators, the microaggressions they encounter in the work place and the coping strategies that are developed to maintain mental, physical and emotional well-being. Seven participants were interviewed to reach themes for exploring racial microaggressions, the reactions and process of these racial microaggressions and coping strategies. Four themes of racial microaggressions were revealed: environmental manifestations, external interactions, stereotypes of Black women and exclusion. The experience of racial microaggressions solicited various reactions and consequences that impacted their careers. There were six themes of coping strategies that were recognized during the interviews: religion and spirituality, armoring, self-care, shifting, community and champions and mentorship. This research provides a unique contribution to the field by providing insight into the nuances of racial microaggressions in college athletics and distinctive ways in which Black senior-level administrators respond to these frequent interactions. The participants shared examples of environmental racial microaggressions and as well as individual racial slights experienced throughout their career. The most prominent impact was to react by educating others. This study highlights the need for athletic directors and presidents to foster inclusive athletic departments that provide opportunity for employees to reach success by being their authentic selves.

description: We provide an improved 3D geometry model of the Northwest Pacific subduction plate. Our model focuses on revealing the morphology, degree of extension and especially the local structure of the subducted plate. The subducting Pacific slabs exhibit a significant variation from north to south over the Kuril-Japan-Izu-Bonin-Mariana Island arc, with a pattern of high-low-high-vertical changes in the subduction dip. The stagnant Pacific slab in the mantle transition zone extends westward as far as eastern China. Localized smaller structures including gaps, tears, and segments are better illustrated in our new model.

description: We have carried out car-following experiments with a 25-car-platoon on an open road section to study the relation between a car's speed and its spacing under various traffic conditions, in the hope to resolve a controversy surrounding this fundamental relation of vehicular traffic. In this paper we extend our previous analysis of these experiments, and report new experimental findings. In particular, we reveal that the platoon length (hence the average spacing within a platoon) might be significantly different even if the average velocity of the platoon is essentially the same. The findings further demonstrate that the traffic states span a 2D region in the speed-spacing (or density) plane. The common practice of using a single speed-spacing curve to model vehicular traffic ignores the variability and imprecision of human driving and is therefore inadequate. We have proposed a car-following model based on a mechanism that in certain ranges of speed and spacing, drivers are insensitive to the changes in spacing when the velocity differences between cars are small. It was shown that the model can reproduce the experimental results well.

description: We propose Kernel Hamiltonian Monte Carlo (KMC), a gradient-free adaptive MCMC algorithm based on Hamiltonian Monte Carlo (HMC). On target densities where classical HMC is not an option due to intractable gradients, KMC adaptively learns the target's gradient structure by fitting an exponential family model in a Reproducing Kernel Hilbert Space. Computational costs are reduced by two novel efficient approximations to this gradient. While being asymptotically exact, KMC mimics HMC in terms of sampling efficiency, and offers substantial mixing improvements over state-of-the-art gradient free samplers. We support our claims with experimental studies on both toy and real-world applications, including Approximate Bayesian Computation and exact-approximate MCMC.

UNSETTLING AUTHENTICITY, QUEERING LANDSCAPES: THE ROLE OF NATURE AT THREE STATE HISTORIC SITES IN DURHAM, NORTH CAROLINA
Creators: name: Biggs, Mary  Titchener
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Today, the outdoor landscapes of Durham's three state historic sites resemble each other closely. Historic Stagville, Bennett Place, and Duke Homestead all have mown grass lawns, large stands of trees, and nature trails. However, none of these sites would have looked this way during the historical periods they represent. In fact, certain aspects of these landscapes actually obscure vital historical truths, and the attention to authenticity inside the buildings of these public historic sites differs considerably from the management and interpretation of the physical landscapes outside. Drawing on scholarship in cultural landscape and authenticity, as well as queer theory, I investigate how site staff manage landscapes around preserved buildings and how visitors experience these managed spaces. Through a queer landscape analytic, I seek to unsettle the constructed natural landscapes in which we learn about the past and deepen our understandings of how articulations of the past act in our present.

description: We present empirical metallicity-dependent calibrations of effective temperature against colours for dwarfs of luminosity classes IV and V and for giants of luminosity classes II and III, based on a collection from the literature of about two hundred nearby stars with direct effective temperature measurements of better than 2.5 per cent. The calibrations are valid for an effective temperature range 3,100 - 10,000 K for dwarfs of spectral types M5 to A0 and 3,100 - 5,700 K for giants of spectral types K5 to G5. A total of twenty-one colours for dwarfs and eighteen colours for giants of bands of four photometric systems, i.e. the Johnson ($UBVR_{\rm J}I_{\rm J}JHK$), the Cousins ($R_{\rm C}I_{\rm C}$), the Sloan Digital Sky Survey (SDSS, $gr$) and the Two Micron All Sky Survey (2MASS, $JHK_{\rm s}$), have been calibrated. Restricted by the metallicity range of the current sample, the calibrations are mainly applicable for disk stars ([Fe/H]$\,\gtrsim\,-1.0$). The normalized percentage residuals of the calibrations are typically 2.0 and 1.5 per cent for dwarfs and giants, respectively. Some systematic discrepancies at various levels are found between the current scales and those available in the literature (e.g. those based on the infrared flux method IRFM or spectroscopy). Based on the current calibrations, we have re-determined the colours of the Sun. We have also investigated the systematic errors in effective temperatures yielded by the current on-going large scale low- to intermediate-resolution stellar spectroscopic surveys. We show that the calibration of colour ($g-K_{\rm s}$) presented in the current work provides an invaluable tool for the estimation of stellar effective temperature for those on-going or upcoming surveys.

Year: 2020

description: ABSTRACT       Naomi Christine Askew: Developing a Nurse-Led Home Health Protocol to Reduce Heart Failure Readmissions      (Under the direction of Meg Zomorodi)       Background: There is a changing the mindset of practitioners and healthcare administrators alike to focus on a more preventative approach in the delivery of health care services that includes addressing the social determinants of health (SDOH). This emphasis on prevention, along with the implementation of the Hospital Readmission Reduction Program (HRRP) by the ACA has resulted in the need for healthcare organizations to strategize methods to reduce costs and prevent readmissions.      Purpose: To develop a protocol for a nursing led intervention to reduce heart failure (HF) readmissions in a home health setting.       Methods: Using quality improvement (QI) methodology to improve care provided to HF patients within a home health setting using telehealth monitoring, proactive HF management and outpatient follow-up to increase access to care.      Results: During the pilot study time frame, a total of 140 patients were admitted with primary or secondary diagnosis of HF. Of these 140 patients admitted, 67 patients were admitted to the partnering cardiology service. Of the 67, only three were qualified to receive home health services and were screened for inclusion for the pilot protocol. However, barriers identified limited the protocol initiation. Therefore, data collection ceased with the focus shifting from patient outcomes to recognition of system based implementation.

The article shows how important the „applied“ management model is for a successful management of mega projects.
Unstable Identities: The Decline of Partisanship in Contemporary Chile
Creators: name: De la Cerda, Nicolas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Between 1990 and 2018 Chile experienced one of Latin America’s most dramatic declines in party identification, from 80% in the early 1990s to less than 20% in 2016. This decline seems puzzling as it coincided with outstanding economic performance, low perceived corruption levels, and an institutionalized party system. This paper argues, and finds quantitative evidence that the decline is related to the short-lived nature of identity-based bonds between parties and citizens generated by the country’s authoritarian experience (1973-1990).  This cleavage decreased after 2000 as right-wing parties distanced themselves from the authoritarian regime for electoral purposes. Their actions ultimately undermined the links between all the main political parties and their constituencies. More broadly, the paper concludes that unless political identities are continually reinforced by political actors they are unlikely to remain stable sources of identification.

description: Time-periodic driving provides a promising route to engineer non-trivial states in quantum many-body systems. However, while it has been shown that the dynamics of integrable systems can synchronize with the driving into a non-trivial periodic motion, generic non-integrable systems are expected to heat up until they display a trivial infinite-temperature behavior. In this paper we show that a quasi-periodic time evolution over many periods can also emerge in systems with weak integrability breaking, with a clear separation of the timescales for synchronization and the eventual approach of the infinite-temperature state. This behavior is the analogue of prethermalization in quenched systems. The synchronized state can be described using a macroscopic number of approximate constants of motion. We corroborate these findings with numerical simulations for the driven Hubbard model.

description: We review the status of String Gas Cosmology after the 2015 Planck data release. String gas cosmology predicts an almost scale-invariant spectrum of cosmological perturbations with a slight red tilt, like the simplest inflationary models. It also predicts a scale-invariant spectrum of gravitational waves with a slight blue tilt, unlike inflationary models which predict a red tilt of the gravitational wave spectrum. String gas cosmology yields two consistency relations which determine the tensor to scalar ratio and the slope of the gravitational wave spectrum given the amplitude and tilt of the scalar spectrum. We show that these consistency relations are in good agreement with the Planck data. We discuss future observations which will be able to differentiate between the predictions of inflation and those of string gas cosmology.

Formal and informal mentorship relationships seem to increase new and early career teacher (ECT) retention. The purpose of this study is to ascertain the impact of formal and informal mentorship on new and ECT retention in Northern Alberta. Semi-structured interviews with three teachers who moved and chose to stay in Northern Alberta help clarify the factors leading to teachers remaining in Northern Alberta to teach. Participants felt both

formal and informal mentorship relationships were important and helpful for their growth as new and ECTs. They also felt a feeling of community and a culture of collaboration were key factors in their decision to stay in their Northern Alberta schools. Conclusions drawn are

feelings of community and being a part of collaborative planning efforts increases the desire for new and ECTs to stay and teach in Northern Alberta communities. Recommendations for school and divisional leaders are to invest in both strong centralized and school-based mentorship programs and supporting a culture of collaboration at both the school and division levels to help increase retention of new and ECTs.

description: The first neutron texture diffractometer in China has been built at China Advanced Research Reactor due to the strong demands of texture measurement with neutrons from domestic user community. This neutron texture diffractometer has high neutron intensity, moderate resolution and is mainly applied to study the texture in the commonly used industrial materials and engineering components. In this paper, the design and characteristics of this instrument are described. The results for calibration with neutrons and quantitative texture analysis of Zr alloy plate are presented. The comparison of texture measurement among different neutron texture diffractometer of HIPPO at LANSCE, Kowari at ANSTO and neutron texture diffractometer at CARR illustrates the reliable performance of this texture diffractometer.

title: Accurate reduced models for the pH oscillations in the urea-urease reaction confined to giant lipid vesicles
Creators: name: Straube, Arthur
name: Winkelmann, Stefanie
name: Höfling, Felix
Year: 2022

description: Our theoretical study concerns an urea-urease-based pH oscillator confined to giant lipid vesicles. Under suitable conditions, differential transport of urea and hydrogen ion across the unilamellar vesicle membrane periodically resets the pH clock that switches the system from acid to basic, resulting in self-sustained oscillations. We analyse the structure of the limit cycle, which controls the dynamics for giant vesicles and dominates the strongly stochastic oscillations in small vesicles of submicrometer size. To this end, we derive reduced models, amenable to analytic treatments, and show that the accuracy of predictions, including the period of oscillations, is highly sensitive to the choice of the reduction scheme. In particular, we suggest an accurate two-variable model and show its equivalence to a three-variable model that admits an interpretation in terms of a chemical reaction network. The accurate description of a single pH oscillator appears crucial for rationalizing experiments and understanding communication of vesicles and synchronization of rhythms.

description: Astrophysical tests of the stability of Nature's fundamental couplings are a key probe of the standard paradigms in fundamental physics and cosmology. In this report we discuss updated constraints on the stability of the fine-structure constant $α$ and the proton-to-electron mass ratio $μ=m_p/m_e$ within the Galaxy. We revisit and improve upon the analysis by Truppe {\it et al.} by allowing for the possibility of simultaneous variations of both couplings and also by combining them with the recent measurements by Levshakov {\it et al.} By considering representative unification scenarios we find no evidence for variations of $α$ at the 0.4 ppm level, and of $μ$ at the 0.6 ppm level; if one uses the Levshakov bound on $μ$ as a prior, the$α$ bound is improved to 0.1 ppm. We also highlight how these measurements can constrain (and discriminate among) several fundamental physics paradigms.

description: Advancements in gravitational-wave interferometers, particularly the next generation, are poised to profoundly impact gravitational wave astronomy and multimessenger astrophysics. A hybrid quantum algorithm is proposed to carry out quantum inference of parameters from compact binary coalescences detected in gravitational-wave interferometers. It performs quantum Bayesian Inference with Renormalization and Downsampling (qBIRD). We choose binary black hole (BBH) mergers from LIGO observatories as the first case to test the algorithm, but its application can be extended to more general instances. The quantum algorithm is able to generate corner plots of relevant parameters such as chirp mass, mass ratio, spins, etc. by inference of simulated gravitational waves with known injected parameter values with zero noise, Gaussian noise and real data, thus recovering an accuracy equivalent to that of classical Markov Chain Monte Carlo inferences. The simulations are performed with sets of 2 and 4 parameters. These results enhance the possibilities to extend our capacity to track signals from coalescences over longer durations and at lower frequencies extending the accuracy and promptness of gravitational wave parameter estimation.

description: The aim of this study was to determine the impact of inter-professional teaching on the application of ergonomic operator and patient positioning. A randomized case-control study was conducted with 83 first-year dental students at the UNC Chapel Hill Adams School of Dentistry. Forty-nine percent (n=41) of the students solicited participated. All students participated in a didactic lecture on ergonomics, along with a pre-clinical practice session with peer patients. During the clinical practice session students in the case group received ten minutes of one-on-one individualized instruction. Two weeks later, all students were assessed using a rubric on operator and patient positioning, while simulating restorative work. There was a statistically significant difference between the two groups with respect to the composite ergonomic compliance score (p=0.005), operator shoulder abduction position (p=0.03), and lateral flexion of the spinal column (p=0.02). Hands-on individualized instruction positively effects ergonomic compliance.

description: Quasi-2D Coulomb systems are of fundamental importance and have attracted much attention in many areas nowadays. Their reduced symmetry gives rise to interesting collective behaviors, but also brings great challenges for particle-based simulations. Here, we propose a novel algorithm framework to address the $O(N^2)$ simulation complexity associated with the long-range nature of Coulomb interactions. First, we introduce an efficient Sum-of-Exponentials (SOE) approximation for the long-range kernel associated with Ewald splitting, achieving uniform convergence in terms of inter-particle distance, which reduces the complexity to $O(N^{7/5})$. We then introduce a random batch sampling method in the periodic dimensions, the stochastic approximation is proven to be both unbiased and with reduced variance via a tailored importance sampling strategy, further reducing the computational cost to $O(N)$. The performance of our algorithm is demonstrated via various numerical examples. Notably, it achieves a speedup of $2\sim 3$ orders of magnitude comparing with Ewald2D method, enabling molecular dynamics (MD) simulations with up to $10^6$ particles on a single core. The present approach is therefore well-suited for large-scale particle-based simulations of Coulomb systems under confinement, making it possible to investigate the role of Coulomb interaction in many practical situations.

description: We present ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC 043234 ($d\simeq90$ Mpc) by the All-Sky Automated Survey for SuperNovae (ASAS-SN). The source had a peak bolometric luminosity of $L\simeq10^{44}$ ergs s$^{-1}$ and a total integrated energy of $E\simeq7\times10^{50}$ ergs radiated over the $\sim6$ months of observations presented. The UV/optical emission of the source is well-fit by a blackbody with roughly constant temperature of $T\sim35,000$ K, while the luminosity declines by roughly a factor of 16 over this time. The optical/UV luminosity decline is broadly consistent with an exponential decline, $L\propto e^{-t/t_0}$, with $t_0\simeq60$ days. ASASSN-14li also exhibits soft X-ray emission comparable in luminosity to the optical and UV emission but declining at a slower rate, and the X-ray emission now dominates. Spectra of the source show broad Balmer and helium lines in emission as well as strong blue continuum emission at all epochs. We use the discoveries of ASASSN-14li and ASASSN-14ae to estimate the TDE rate implied by ASAS-SN, finding an average rate of $r \simeq 4.1 \times 10^{-5}~{\rm yr}^{-1}$ per galaxy with a 90% confidence interval of $(2.2 - 17.0) \times 10^{-5}~{\rm yr}^{-1}$ per galaxy. ASAS-SN found roughly 1 TDE for every 70 Type Ia supernovae in 2014, a rate that is much higher than that of other surveys.

A REVIEW OF THE ROLE OF CLEANERS IN ESTABLISHING AND MAINTAINING ENVIRONMENTAL HEALTH CONDITIONS IN HEALTHCARE FACILITIES IN MALAWI
Creators: name: Schram, Hayley E.

description: Healthcare facility (HCF) cleaners, including ward attendants and grounds laborers, play an important role in preventing healthcare-acquired infections and promoting a safe healthcare environment. There is little evidence describing cleaner roles in HCFs in low- and middle-income countries and the factors that facilitate and constrain their roles and responsibilities. In response, we analyzed data from 57 interviews with cleaners in 45 rural HCFs in Malawi.       Cleaner constraints included: inadequate training on infection prevention and control and waste management; insufficient work-related resources; performing tasks unrelated to core responsibilities; risk of work-related injuries; and occasional disrespect from medical staff and patients. Job facilitators included: positive collaboration with medical staff and highly expressed job satisfaction.       Male ward attendants attained higher education than females and reported excess physical tasks, such as stocking supplies; females reported performing more administrative duties. Descriptions of cleaner roles did not differ by region, HCF type, cleaner type, or gender.

The Indigenous Struggle Water Rights in Seventeenth Century New Spain
Creators: name: Love, Cody Joseph
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: This project examines how indigenous agrarian communities in Mexico’s Central Highlands used both legal and extralegal strategies to maintain their access to water while facing increasing environmental changes and competition from private landholders, cities, and other indigenous communities during the seventeenth century. A careful analysis of legal disputes over water reveals how indigenous communities leveraged their legal statuses, rhetorical strategies, and direct means of control to maintain their ability to irrigate their fields during a period of increasing demand for water. It also shows that despite the changes in imperial policy, indigenous communities continued trying to exploit hegemonic authority in local power struggles to assert their communal sovereignty. As such, legal and direct confrontations over water access were more than struggles for subsistence or economic gain. Rather, these struggles were assertions of local power over the landscape in which indigenous communities vied against each other and an increasing colonial presence.
P-V criticality of charged dilatonic black holes

description: In this paper, we investigate the critical behavior of charged black holes of Einstein-Maxwell-dilaton gravity in the presence of two Liouville-type potentials which make the solution asymptotically neither flat nor AdS and has a parameter $% Λ$ treated as a thermodynamic quantity that can vary. We obtain a Smarr-type relation for charged dilatonic black holes and find out that the volume is different from the geometrical volume. We study the analogy of the Van der Waals liquid-gas system with the charged dilatonic black hole system while we treat the black hole charge as a fixed external parameter. Moreover, we show that the critical values for pressure, temperature and volume are physical provided the coupling constant of dilaton gravity is less than one and the horizon is sphere. Finally, we calculate the critical exponents and show that they are universal and are independent of the details of the system although the thermodynamic quantities depend on the dilaton parameter and the dimension of the spacetime.

description: Bacterial biofilms are usually assumed to originate from individual cells deposited on a surface. However, many biofilm-forming bacteria tend to aggregate in the planktonic phase so that it is possible that many natural and infectious biofilms originate wholly or partially from pre-formed cell aggregates. Here, we use agent-based computer simulations to investigate the role of pre-formed aggregates in biofilm development. Focusing on the initial shape the aggregate forms on the surface, we find that the degree of spreading of an aggregate on a surface can play an important role in determining its eventual fate during biofilm development. Specifically, initially spread aggregates perform better when competition with surrounding unaggregated bacterial cells is low, while initially rounded aggregates perform better when competition with surrounding unaggregated cells is high. These contrasting outcomes are governed by a trade-off between aggregate surface area and height. Our results provide new insight into biofilm formation and development, and reveal new factors that may be at play in the social evolution of biofilm communities.

The Effects of Prolonged Sitting and Mental Stress: A Synapse to Cerebrovascular Function
Creators: name: Blackwell, Jade
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Acute bouts of prolonged sitting and stress may lead to cerebrovascular disruptions. This study evaluated the effects of prolonged (2hrs) sitting and mental stress on cerebrovascular function. Six participants (42.8 [7.7] y, 33% F, 24.8 [1.4] kg/m2) were randomized to sit for 2hrs (LONG) or 20min (SHORT) prior to receiving a mental stressor. Brain Pulse Wave Velocity (brainPWV) was measured using a Transcranial Doppler. Executive function was assessed using the Trail Making Test (TMT), and Verbal Fluency Test (VFT). brainPWV increased by 11.1 cm/s after 2hrs of uninterrupted sitting, although it was not statistically significant (P=0.329, ES: 0.45). There was a significant condition effect (P=0.004, ES: -0.99) for brainPWV pre vs. post mental arithmetic test. There were no significant differences between conditions for the TMT (P=0.282, ES: 0.49), and VFT (P=0.907, ES: 0.50). Prolonged sitting combined with mental stress does increase brainPWV, however it has no effect on executive function.

description: This is the documentation on current results of a research project jointly conducted by Stiftung Deutsche Kinemathek (SDK) and Zuse Institute Berlin (ZIB). In this project, we are working on a practical yet sustainable archiving solution for audiovisual material. In the course of the project two major obstacles were identified: 1) Metadata is collected according to standards established in the community but lacking a prescribed serialisation format. 2) Storage size of audiovisual material and time scales of production processes make it often impractical to defer submission for archival storage until all components have arrived and can be processed in one go.
