Multifamily Recycling: An Evaluation of Existing Municipal Recycling Mandates and Payment Structures
Creators: name: Schwartz, Lily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: In communities of all sizes across the United States, multifamily residents have lower levels of access to recycling services than single-family residents (SPC, 2016). To address this challenge and widely promote the practice of recycling, many states and municipalities have enacted recycling mandates. This thesis aims to answer two main research questions: “How effective are existing municipal recycling mandates for providing access to recycling services to residents of multifamily properties?” and “How do different payment structures used to fund multifamily recycling services distribute costs amongst residents of single-family and multifamily properties? Is this cost distribution perceived as fair?” Two primary methods of data collection were used to answer these questions: first, the content of municipal recycling mandates for multifamily properties was analyzed using three standards (convenience, capacity, and compliance agency); second, a case study was conducted to describe and compare the payment structures used to fund multifamily recycling in two North Carolinian municipalities. The majority of municipal recycling mandates were proved to be ineffective by at least one of the three standards for measuring access to recycling services, and the case study confirmed that a payment structure was considered less fair if multifamily residents were required to pay the same amount as single-family residents and had less or no access to municipal recycling services.

description: This scoping review explores the breadth and depth to which Domestic Violence Intervention Programs (DVIPs) in the United States and globally: (a) incorporate components that address the relationship between intimate partner violence (IPV) and social injustice, racism, economic inequality, and adverse childhood experiences (ACEs); (b) use restorative (RJ)/transformative justice (TJ) practices, individualized case management, partnerships with social justice actors, and strengths-based parenting training in current programming; and (c) measure effectiveness. In 2021, we searched 12 academic databases using a combination of search terms and Medical Subject Headings. In all, 27 articles that discussed at least one key concept relative to DVIP curricula were included in the final review. Findings suggest that very few DVIPs address ACEs and/or the relationship between structural violence, social inequality, and IPV perpetration. Even fewer programs use restorative practices including RJ or TJ. Furthermore, DVIPs use inconsistent methods and measures to evaluate effectiveness. To respond to IPV perpetration more effectively and create lasting change, DVIPs must adopt evidence-informed approaches that prioritize social and structural determinants of violence, trauma-informed care, and restoration.
Finding Links between Obesity and Diabetes: Using Diacylglycerol Kinase to Regulate Insulin Signaling

description: In the U.S., two-thirds of adults are overweight or obese, with 35.7% of them - nearly 78 million people – obese. What used to be a disease that only afflicted adults is now also increasingly being diagnosed in children, contributing to ever-growing obesity rates. In particular, obesity and diabetes are closely linked, with obese people at higher risk for developing type 2 diabetes. All this only further intensifies the urgent need to address obesity and type 2 diabetes. In particular, we need to understand how the two conditions are linked and what metabolic processes are involved, in order to develop treatment and prevention strategies that will ultimately reduce the burden of type 2 diabetes on healthcare.
My project looks at how the triacylglycerol synthesis and insulin signaling pathways are linked. In particular, we are studying how lipid intermediates cause insulin resistance in hepatocytes. We are interested in whether phosphatidic acid (PA) and diacylglycerol (DAG) affect Akt phosphorylation, and the mechanism by which PA and DAG might inhibit insulin signaling. Diacylglycerol kinase (DGK) is the enzyme that catalyzes conversion of DAG to PA, and was used as a tool to manipulate the cellular content of PA and DAG. The content and activity of DGK was adjusted by DGK overexpression in mouse hepatocytes, thus altering the balance of PA and DAG. The physiological consequences were then used to determine how insulin signaling is affected. Our hypothesis is that DGK regulates insulin signaling by changing intracellular PA and DAG levels. The isoform used was the DGKθ isoform. Our results showed that PA is associated with impaired insulin action in mouse hepatocytes, but DAG is not.

description: Structural, elastic, electronic properties and the features of inter-atomic bonding in hypothetical Ir-based carbides-antiperovskites Ir3MC (M=Ti, Zr, Nb and Ta), as predicted from first-principles calculations, have been investigated for a first time. Their elastic constants, bulk, shear and Young`s moduli, compressibility, Poisson`s ratio, Debye temperature have been evaluated, and their stability, character of elastic anisotropy, brittle / ductile behavior, as well as electronic structure have been explored in comparison with binary carbides MC having NaCl-type structure. Authors hope that the presented results will be useful for future synthesis of these phases, as well as for extending the knowledge about the group of antiperovskite-type promising materials.

description: Ferromagnetic contacts are widely used to inject spin polarized currents into non-magnetic materials such as semiconductors or 2-dimensional materials like graphene. In these systems, oxidation of the ferromagnetic materials poses an intrinsic limitation on device performance. Here we investigate the role of ex-situ transferred chemical vapour deposited hexagonal boron nitride (hBN) as an oxidation barrier for nanostructured cobalt and permalloy electrodes. The chemical state of the ferromagnets was investigated using X-ray photoemission electron microscopy owing to its high sensitivity and lateral resolution. We have compared the oxide thickness formed on ferromagnetic nanostructures covered by hBN to uncovered reference structures. Our results show that hBN reduces the oxidation rate of ferromagnetic nanostructures suggesting that it could be used as an ultra-thin protection layer in future spintronic devices.

description: BACKGROUND: Delivery of cancer treatments, such as chemotherapy, requires a complex set of decisions that can change over time. Traditional measures of chemotherapy delivery, such as relative dose intensity, measure the amount of chemotherapy received by the end of treatment but mask the timing of dose reductions, delays, and discontinuation. These events may be important for delivering timely interventions to support adherence and lower the risk of recurrence.
MATERIALS AND METHODS: We used an institutional database to identify women diagnosed with stage I-III breast cancer receiving adjuvant chemotherapy with a standard 4-cycle regimen of docetaxel + cyclophosphamide (TC, every 21 days) from April 2014 to December 2019. LCD was calculated as the amount of a given chemotherapy agent delivered at a specified time, t, divided by the total planned standard chemotherapy dose at time t. We visualized LCD curves for each chemotherapy agent and reported the median LCD and interquartile range (IQR) at the end of the regimen, overall and by age group (<65 years vs. 65+ years).
RESULTS: The study population included 80 women. At the end of treatment, overall median LCDs for both cyclophosphamide and docetaxel were 100% (IQR: 99.6%, 100%), suggesting that TC was well tolerated. However, the lower quartile LCD for cyclophosphamide was 98.7% in older women treated with TC compared with 99.7% in younger women.
CONCLUSION: Within our cohort, adjuvant TC was well tolerated with LCD curves showing largely on-time and full-dose administration. Subgroup analyses showed only slight decreases in adjuvant TC LCD for patients aged 65+ versus <65 years.

The Association between Water Lead Levels and Blood Lead Levels: A Systematic Review
Creators: name: Komandur, Abhishek
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Lead adversely impacts health when consumed through drinking water, but there is no standard model describing the relationship between lead in water and blood. To better understand this relationship, I conducted a systematic literature review. Eighteen studies published after 1995 were identified from online databases and other sources, of which eleven measured both water lead and blood lead. All 11 papers showed a statistically significant positive correlation between water and blood lead. However, there is large variance in how these papers modeled the relationship, and limitations of the studies limit their generalizability. The remaining seven papers estimated blood lead from water lead using physiologically-based pharmacokinetic models. These results demonstrate a deficit in information on dose-response relationships between water lead and blood lead. A better understanding would aid in assessing the health risks of lead exposure from drinking water, which in turn would help with regulatory policy-making.
Open Access and Discovery Tools: How do Primo Libraries Manage Green Open Access Collections?

description: Scholarly Open Access repositories contain lots of treasures including rare or otherwise unpublished materials and articles that scholars self-archive, often as part of their institution's mandate. But it can be hard to discover this material unless users know exactly where to look. Since the very beginning, libraries have played a major role in supporting the OA movement. Next to all services they can provide to support the deposit of research output in the repositories, they can make Open Access materials widely discoverable by their patrons through general search engines (Google, Bing...), specialized search engines (like Google Scholar) and library discovery tools, thus expanding their collection to include materials that they would not necessarily pay for. In this paper, we intend to focus on two aspects regarding Open Access and Primo discovery tool. In early 2013, Ex Libris Group started to add institutional repositories to Primo Central Index (PCI), their mega-aggregation of hundreds of millions of scholarly e-resources. After 2 years, it may be interesting to take stock of the current situation of PCI regarding Open Access institutional repositories. On basis of a survey to carry out among the Primo community, the paper also shows how libraries using Primo discovery tool integrate Green Open Access contents in their catalog. Two major ways are possible for them: Firstly, they can directly harvest, index and manage any repository in their Primo and display those free contents next to the more traditional library collections; Secondly, if they are PCI subscribers, they can quickly and easily activate any, if not all, of the Open Access repositories contained PCI, making thus the contents of those directly discoverable to their end users.

description: This paper is concerned with the interfacial thermal resistance for polymer composites reinforced by various covalently functionalised graphene. By using molecular dynamics simulations, the obtained results show that the covalent functionalisation in graphene plays a significant role in reducing the graphene-paraffin interfacial thermal resistance. This reduction is dependent on the coverage and type of functional groups. Among the various functional groups, butyl is found to be the most effective in reducing the interfacial thermal resistance, followed by methyl, phenyl and formyl. The other functional groups under consideration such as carboxyl, hydroxyl and amines are found to produce negligible reduction in the interfacial thermal resistance. For multilayer graphene with a layer number up to four, the interfacial thermal resistance is insensitive to the layer number. The effects of the different functional groups and the layer number on the interfacial thermal resistance are also elaborated using the vibrational density of states of the graphene and the paraffin matrix. The present findings provide useful guidelines in the application of functionalised graphene for practical thermal management.

Surviving the Casting Economy: Reality Television and Cultural Citizenship, Consumer Labor, and Commodification
Creators: name: Hribar, Casey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The primary aim of the thesis I am creating is to explore the complex and often taken for
granted role reality television has on contemporary American society. Discourses I will engage
in to achieve this goal include neoliberalism, the concept of celebrity, consumer labor, and the
irony bribe, among others. Neoliberalism, as defined by Teppo Eskelinen, is a political ideology
that is marked by minimal government involvement in the lives of citizens. Free markets and
individual responsibility outweigh the idea of a public good (Eskelinen 751). I will use this
ideology to critique reality television’s impact on cultural citizenship. I will unpack the concept
of celebrity, which, as defined by Matthew Guterl, “is a person in the public eye who, for better
or worse, has earned fame or infamy, or found renown or scandal, as a consequence of some act
or supposed quality, and is celebrated as a result” (80). I will use this definition to analyze the
desire to participate in reality television, and assess cast members’ need to market themselves
further than their fifteen minutes of fame.
I will also utilize the irony bribe, coined by Dana Cloud. The irony bribe essentially
refers to the ability of RTV to be both real and fake at the same time, providing an ironic
detachment from the program, while also inspiring a fervent love for it (Cloud 413). I will
analyze this quality in reference to something I call the casting economy. Finally, I will utilize
Mark Andrejevic’s concept of consumer labor to analyze reality television’s impact on the
economy, as well as media and technology development both nationally and internationally.
Under consumer labor, viewers have the ability to give valuable input on what they would like to
experience, with their only compensation being participation in new, seemingly democratic
television programming, for producers and editors to comb through and utilize in their
programming, ensuring its success (Andrejevic, “Reality TV” 17-18; Andrejevic, “The Kindler,
Gentler Gaze of Big Brother” 256-257; Andrejevic, “The Work of Being Watched” 230).
One term I have coined that will be used to tie many of these themes together is the
“casting economy”. If reality television were truly “real” producers would be able to pull any
random number of people off the street, place them in an enclosed setting, and see riveting drama
soar. However, this is not the case, and a whole economy of its own, the casting economy, has
risen behind this genre to ensure its success. The casting economy includes everything from the
never-ending well of potential contestants seeking fame, selecting contestants to maintain a
neoliberal agenda as well as the irony bribe, and the utilization of different locals both nationally
and internationally to create sensational, yet addictive programming.

description: Alkaline-earth and ytterbium cold atomic gases make it possible to simulate SU(N)-symmetric fermionic systems in a very controlled fashion. Such a high symmetry is expected to give rise to a variety of novel phenomena ranging from molecular Luttinger liquids to (symmetry- protected) topological phases. We review some of the phases that can be stabilized in a one dimensional lattice. The physics of this multicomponent Fermi gas turns out to be much richer and more exotic than in the standard SU(2) case. For N > 2, the phase diagram is quite rich already in the case of the single-band model, including a molecular Luttinger liquid (with dominant superfluid instability in the N-particle channel) for incommensurate fillings, as well as various Mott-insulating phases occurring at commensurate fillings. Particular attention will be paid to the cases with additional orbital degree of freedom (which is accessible experimentally either by taking into account two atomic states or by putting atoms in the p-band levels). We introduce two microscopic models which are relevant for these cases and discuss their symmetries and strong coupling limits. More intriguing phase diagrams are then presented including, for instance, symmetry protected topological phases characterized by non-trivial edge states.

description: We propose and investigate a spin transistor device consisting of two ferromagnetic leads connected by a two-dimensional topological insulator as the channel material. It exploits the unique features of the topological spin-helical edge states, such that the injected carriers with a non-collinear spin-direction would travel through both edges and show interference effect. The conductance of the device can be controlled in a simple and allelectric manner by a side-gate voltage, which effectively rotates the spin-polarization of the carrier. At low voltages, the rotation angle is linear in the gate voltage, and the device can function as a good spin-polarization rotator by replacing the drain electrode with a paramagnetic material.

Democratizing Afghanistan: An Analysis of Foreign Implementation Efforts and the Obstacles Preventing Success
Creators: name: Herzog, Claire C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: For nearly a century, the United States has attempted to influence countries abroad,
hoping to create democratic governments where they do not already exist. Whether or not
these attempts have been successful, the U.S. continues to pursue the ideal of democracy,
particularly in post-conflict regions or in countries suffering from ongoing conflict. This is no
different in Afghanistan. In response to the 9/11 terrorist attacks in New York and
Washington, D.C., the U.S. launched the 2001 invasion of Afghanistan with the goal of
eradicating both al Qaeda and the Taliban. After a swift military victory, the U.S., its allies,
and Afghanistan signed the Bonn Agreement, establishing guidelines to create a new
representative, democratic government that would hopefully flourish in the following years.
However, thirteen years later, the region is still fraught with violence and corruption, and
democracy is far from legitimate or functioning. This should inspire U.S. policymakers to
look deeper into why democracy has not found a welcoming home in Afghanistan—is it
Afghanistan, its troublesome history, its ethnic divides, and its recurring flirtation with
terrorism, or is it a failure on the part of the U.S. and its allies?
In order to answer this question, my thesis will first explain how democracy
promotion came to be such a prominent aspect of American foreign policy, how it has
morphed through time, and how effective it has been in different countries and situations.
After describing the history of democratization, both in general and in Afghanistan, my thesis
will move to describe and analyze the various impediments to Afghan democracy that are
currently in place. By listing and explaining what has been responsible for undermining
democracy in Afghanistan, the reader will then be able to understand if there are any possible
solutions that could remove or circumvent these impediments, and whether or not the United
States and its allies can be involved in such solutions. Finally, this paper will discuss the past
attempts at democracy implementation in Afghanistan since the enactment of the Bonn
Agreement and detail the successes and failures of these efforts. Essentially, it is clear that
these three elements come together to explain that even a massive U.S. and allied effort is not
enough to simultaneously stem the tide of Taliban insurgency, overcome a history of
instability and entrenched ethnic divides, and successfully complete reconstruction efforts.
However, there is a chance that, in the distant future, the general population of Afghanistan
could rise up against the Taliban, against the warlords corrupting the government, and
against poverty and illiteracy so that the country can move toward an organic democracy,
with the terms, pace, and structure dictated by the Afghan citizens.

description: This study applied qualitative methods and a user design approach to develop and iteratively refine a model for a virtual reality intervention designed to supplement standard inpatient treatment for adolescents hospitalized for suicide-related crises: the practice experiences for school reintegration (PrESR). The PrESR model allows patients to practice therapeutic skills within an immersive school environment to increase skill knowledge and skill use and to improve school reintegration. Adolescents previously hospitalized for suicide-related thoughts and behaviors (n = 13), hospital professionals with experience providing supports to hospitalized adolescents (n = 7), and school professionals with experience supporting adolescents with suicide-related risks (n = 12) completed focus group and/or one-on-one interviews to inform the development of the PrESR model. Transcribed interviews were analyzed using content analysis, and structured feedback was analyzed by calculating frequencies. Participating adolescents were between the ages of 13 and 18, identifying their race as White (61%), Asian (7.7%), American Indian and Black (7.7%), or Black (7.7%; note that 15.4% preferred not to answer) and their ethnicity as Hispanic (23%) or non-Hispanic (77%). Adolescents identified their gender as girl or woman (46%), boy or man (38%), or "some other way" (15%). A majority of adolescent and professional participants endorsed the PrESR as holding the potential to promote skill learning. Feedback addressed improvements to scenarios and skills; safety concerns, constraints to consider, and barriers to implementation; and information to include in the treatment manual. Findings also informed the types of difficulties adolescents face in schools and the potential feasibility of a virtual reality intervention to enhance standard inpatient care of adolescents hospitalized for suicide-related crises.

Year: 2018

description: With increasing effects of climate change, cities and towns are becoming more interested in developing resilient infrastructure. Bicycle infrastructure, one popular form of resilient infrastructure is becoming more present in towns and cities. Town qualities, such as close-knit communities, smaller sized blocks, and density make them especially suitable for bicycle infrastructure. My focus on Beaufort, North Carolina, highlights different challenges and opportunities small coastal towns can provide. The progress and potential of bicycle infrastructure in Beaufort highlight how it can guide a community into becoming more prepared for climate change. This research will expand the relatively new area of bicycle infrastructure in small communities and bolster research on resilient solutions for coastal communities facing climate change.

description: We present a method for coherently combining short data segments from gravitational-wave detectors to improve the sensitivity of semi-coherent searches for continuous gravitational waves. All-sky searches for continuous gravitational waves from unknown sources are computationally limited. The semi-coherent approach reduces the computational cost by dividing the entire observation timespan into short segments to be analyzed coherently, then combined together incoherently. Semi-coherent analyses that attempt to improve sensitivity by coherently combining data from multiple detectors face a computational challenge in accounting for uncertainties in signal parameters. In this article, we lay out a technique to meet this challenge using summed Fourier transform coefficients. Applying this technique to one all-sky search algorithm called TwoSpect, we confirm that the sensitivity of all-sky, semi-coherent searches can be improved by coherently combining the short data segments. For misaligned detectors, however, this improvement requires careful attention when marginalizing over unknown polarization parameters. In addition, care must be taken in correcting for differential detector velocity due to the Earth's rotation for high signal frequencies and widely separated detectors.

description: We report on the X-ray spectral behavior within the steady states of GRS 1915+105. Our work is based on the full data set on the source obtained using the Proportional Counter Array on the Rossi X-ray Timing Explorer and 15 GHz radio data obtained using the Ryle Telescope. The steady observations within the X-ray data set naturally separated into two regions in the color-color diagram and we refer to them as steady-soft and steady-hard. GRS 1915+105 displays significant curvature in the coronal component in both the soft and hard data within the {\it RXTE}/PCA bandpass. A majority of the steady-soft observations displays a roughly constant inner disk radius (R_in), while the steady-hard observations display an evolving disk truncation which is correlated to the mass accretion rate through the disk. The disk flux and coronal flux are strongly correlated in steady-hard observations and very weakly correlated in the steady-soft observations. Within the steady-hard observations we observe two particular circumstances when there are correlations between the coronal X-ray flux and the radio flux with log slopes η~0.68 +/- 0.35 and η~ 1.12 +/- 0.13. They are consistent with the upper and lower tracks of Gallo et al. (2012), respectively. A comparison of model parameters to the state definitions show that almost all steady-soft observations match the criteria of either thermal or steep power law state, while a large portion of the steady-hard observations match the hard state criteria when the disk fraction constraint is neglected.

The Effects of Smoking on Antibody Response to the A/California/7/2009 (H1N1)pdm09-like Virus in the Influenza Vaccine

description: The use of tobacco has been an important public health concern within the past several
decades and is still expected to be problematic well into the future. Recently, cigarette smoke
has been associated with a decreased immune response to the influenza vaccine; however, there
is limited data regarding previous smokers and how the immune system functions following the
cessation of smoking. The focus of this study was to determine how the antibody response to the
H1N1pdm09-like strain within the influenza vaccine varied among current smokers. previous
smokers, and nonsmokers as well as between lean and obese individuals within each group. Pre- and
post-vaccination serum samples from 60 study subjects from the 2016-2017 influenza season
were analyzed via hemagglutination inhibition assays (HAl) to determine the antibody titers in
response to the H 1 N 1 pdm09-like strain in the influenza vaccine. There was a general trend for
the lean subjects to have higher HAl titers than the obese subjects; however, this trend was
insignificant. Additionally, it was found that the HAl titer differences between current smokers,
previous smokers, and nonsmokers were insignificant. The percent sero-protected (the
percentage of individuals with an HAl titer of 40 or greater) and the titer fold change (a measure
ofthe antibody level change between pre-vaccination and post-vaccination) were both found to
be insignificant between all six groups. Several limitations of this study such as a small sample
size may have led to insignificant results; however, although this study did not produce
significant results, this does not mean that smoking does not have an effect on antibody levels.
More studies are needed to analyze this relationship.

description: The fragmentation times corresponding to the loss of the chromophore (C$α$-- C$β$ bond dissociation channel) after photoexcitation at 263 nm have been investigated for several small peptides containing tryptophan or tyrosine. For tryptophan-containing peptides, the aromatic chromophore is lost as an ionic fragment (m/z 130), and the fragmentation time increases with the mass of the neutral fragment. In contrast, for tyrosine-containing peptides the aromatic chromophore is always lost as a neutral fragment (mass = 107 amu) and the fragmentation time is found to be fast (\textless{}20 ns). These different behaviors are explained by the role of the postfragmentation interaction in the complex formed after the C$α$--C$β$ bond cleavage.

METHODS: The authors conducted a cross-sectional data analysis using data from the Pregnancy Risk Assessment and Monitoring System from 2016 to 2018 to analyze rural-urban differences in the receipt of medical visits and care content delivery during the prepregnancy year, as well as the prenatal and postpartum periods among birthing people in the US, using survey-weighted multivariable logistic regression models.
RESULTS: Rural-dwelling birthing people were significantly less likely to attend a medical visit in the prepregnancy year or postpartum period, even when controlled for sociodemographic and clinical characteristics. Compared to their urban counterparts, they were also less likely to receive comprehensive screening and counseling in the prepregnancy and postpartum maternity phases.
CONCLUSION: Efforts to ameliorate rural-urban differences in maternal care access and quality should explicitly adopt multilevel, systemic approaches to policy and program implementation and evaluation. Policymakers and practitioners should consider telehealth as a potential complementary tool to minimize gaps in quality of care which disproportionately impact rural-dwelling birthing people.

description: We present the results of extinction measurements toward the main ejecta shell of the Cassiopeia A supernova (SN) remnant using the flux ratios between the two near-infrared (NIR) [Fe II] lines at 1.26 and 1.64 $μ{\rm m}$. We find a clear correlation between the NIR extinction ($E(J-H)$) and the radial velocity of ejecta knots, showing that redshifted knots are systematically more obscured than blueshifted ones. This internal "self-extinction" strongly indicates that a large amount of SN dust resides inside and around the main ejecta shell. At one location in the southern part of the shell, we measure $E(J-H)$ by the SN dust of 0.23$\pm$0.05 mag. By analyzing the spectral energy distribution of thermal dust emission at that location, we show that there are warm ($\sim$100 K) and cool ($\sim$40 K) SN dust components and that the latter is responsible for the observed $E(J-H)$. We investigate the possible grain species and size of each component and find that the warm SN dust needs to be silicate grains such as MgSiO$_{3}$, Mg$_{2}$SiO$_{4}$, and SiO$_{2}$, whereas the cool dust could be either small ($\leq$0.01 $μ{\rm m}$) Fe or large ($\geq$0.1 $μ{\rm m}$) Si grains. We suggest that the warm and cool dust components in Cassiopeia A represent grain species produced in diffuse SN ejecta and in dense ejecta clumps, respectively.

Kinematic Anomalies in the RESOLVE Survey

description: We are determining rotation curves for the galaxies in the RESOLVE (REsolved Spectroscopy
Of a Local VolumE) survey to identify kinematic anomalies in the ionized and neutral hydrogen
gas. We have developed software for extracting galaxy rotation curves and other useful kinematic
information such as asymmetries and extent from optical spectra of galaxies. We analyze the results
from 60 galaxies, comparing 53 of them to galaxies with corresponding HI profiles. Specifically, we
compare the optically extracted rotation velocities to the HI profile linewidths and find that they
agree, with some scatter. We investigate reasons for the observed discrepancies between the two
types of velocity measurements and conclude that galaxy interactions are a likely mechanism for some
of the disagreement. Furthermore, we conclude that for galaxies with close neighbors the optically
determined rotation velocity yields a more robust result than the velocity determined from the HI
profile linewidth. We also analyze kinematic and mass asymmetries, but find no statistically significant
results.

description: In this paper, we prove that the linearized system of elliptic triangle homographic solution of planar charged three-body problem can be transformed to that of the elliptic equilateral triangle solution of the planar classical three-body problem. Consequently, the results of Mart\'ınez, Samà and Simó ([15] in J. Diff. Equa.) of 2006 and results of Hu, Long and Sun ([6] in Arch. Ration. Mech.Anal.) of 2014 can be applied to these solutions of the charged three-body problem to get their linear stability.

Effects of an extension-constraint functional knee brace on the ankle mechanics of adolescent athletes in a jump-landing task 6 months post-ACL reconstruction
Creators: name: Wilkey, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Context: The prevalence of secondary ACL injury is highest among adolescents. It is
important to understand how both surgery and rehabilitation affect lower extremity
biomechanics in this population because poor lower extremity mechanics can contribute
to ACL tears. Functional knee bracing following reconstructive surgery could potentially
reduce the occurrence of secondary tears by correcting harmful mechanics at the knee.
Altering knee kinetics and kinematics may also have an impact on the mechanics of other
joints in the kinematic chain, particularly the ankle. It is important to monitor for these effects because poor ankle mechanics can potentially contribute to further injury at any of the joints along the kinematic chain, including secondary ACL tear.
Hypothesis: It was hypothesized that wearing a functional knee brace would increase
vertical ground reaction force, decrease ankle range of motion in the sagittal plane, and increase ankle moments in the sagittal plane.
Study Objective: To determine whether or not wearing a functional knee brace during
rehabilitation affects ankle mechanics in patients six months following ACL
reconstruction surgery.
Methods: Twenty adolescent patients who had undergone ACL reconstruction surgery
and were receiving physical therapy were recruited for the study. All subjects were
assessed through motion analysis while performing a stop jump task. Subjects first
completed the task while wearing an extension-constraint functional knee brace on the
surgical limb and then without wearing the brace. For all subjects, data were collected six months following ACL reconstruction surgery. Statistical analysis was run using pairedsamples t-tests with a significant alpha level of .05. Results: There were no significant differences found between the braced and non-braced
conditions for any of the six variables being observed. These variables included peak
vertical ground reaction force, peak dorsiflexion angle, peak plantar flexion angle, total ankle range of motion, peak plantar flexion moment, and peak dorsiflexion moment.
Conclusions: Extension-constraint functional knee bracing seems to have no effect on the
mechanics of the ankle on the surgical side. Clinical Relevance: Clinicians can utilize this type of brace during the rehabilitation process knowing they will not be negatively impacting the mechanics at the ankle.

description: EcoDataCube for Europe comprises multiple land cover, terrain, climatic, soil and vegetation ARCO (Analysis-Ready Cloud-Optimised) layers for continental EU at relatively fine spatial resolutions (30-m to 1-km) for a period of 20 years (2000—2020). In general, the 30-m datasets are based on harmonised time-series of Landsat and Sentinel-2 imagery (GLAD Landsat ARD), multi-source Earth Observation data (e.g. ERA-5, Chelsa climate, MOD11A2, Suomi NPP/VIIRS), and a spatiotemporal ensemble machine learning approach capable of producing per-pixel probabilities and uncertainty outputs. This mapping framework was used to predict 43 land cover classes (compatible with CORINE Land Cover-CLC), 16 forest tree species (potential and realized distributions), and 5 soil properties for 4 depths (i.e. organic carbon, pH, bulk density, clay and sand content). All ARCO layers are publicly accessible as proper Open Data (CC BY) through Web Viewer (https://ecodatacube.eu) and SpatialTemporal Asset Catalog (STAC - https://stac.ecodatacube.eu).

description: Scintillators attract wide research interest for their distinct applications in radiation detection. Elpasolite halides are among the most promising scintillators due to their high structural symmetry and good scintillation performance. Better understanding of their underlying scintillation mechanism opens up new possibilities in scintillator development. In this work, we employ a variety of experimental techniques to study the two mixed-anion elpasolites Cs2NaRBr3I3 (R = La, Y). The emission of intrinsic Cs2NaRBr3I3 with a light yield ranging from 20,000 to 40,000 ph/MeV is dominant by self-trapped exciton emission. Partial substitution of R with Ce introduces a competing emission, the Ce3+ 5d to 4f radiative transition. Ab initio calculations were performed to investigate the electronic structures as well as the binding energies of polarons in Cs2NaRBr6. The calculated large self-trapped exciton binding energies are consistent with the observed high light yield due to self-trapped exciton emission. The unique electronic structure of halide elpasolites as calculated enhances the STE stability and the STE emission. The highly tunable scintillation properties of mixed-anion elpasolites underscore the role of their complex scintillation mechanism. Our study provides guidance for the design of new elpasolites scintillators with exceptional energy resolution and light yield desirable for applications.
