description: In standard cosmology, the growth of structure becomes significant following matter-radiation equality. In non-thermal histories, where an effectively matter-dominated phase occurs due to scalar oscillations prior to Big Bang Nucleosynthesis, a new scale at smaller wavelengths appears in the matter power spectrum. Density perturbations that enter the horizon during the matter-dominated phase grow linearly with the scale factor prior to the onset of radiation domination, which leads to enhanced inhomogeneity on small scales if dark matter thermally and kinetically decouples during the matter-dominated phase. The microhalos that form from these enhanced perturbations significantly boost the self-annihilation rate for dark matter. This has important implications for indirect detection experiments: the larger annihilation rate will result in observable signals from dark matter candidates that are usually deemed untestable. As a proof of principle, we consider Binos in heavy supersymmetry with an intermediate extended Higgs sector and all other superpartners decoupled. We find that these isolated Binos, which lie under the neutrino floor, can account for the dark matter relic density while also leading to observable predictions for Fermi-LAT. Current limits on the annihilation cross section from Fermi-LAT's observations of dwarf spheroidal galaxies may already constrain Bino dark matter up to masses $\mathcal{O}(300)$ GeV, depending on the internal structure of the microhalos. More extensive constraints are possible with improved gamma-ray bounds and boost calculations from $N$-body simulations.

description: Conclusive evidence of order by disorder is scarce in real materials. Perhaps one of the strongest cases presented has been for the pyrochlore XY antiferromagnet Er2Ti2O7, with the ground state selection proceeding by order by disorder induced through the effects of quantum fluctuations. This identification assumes the smallness of the effect of virtual crystal field fluctuations that could provide an alternative route to picking the ground state. Here we show that this order by virtual crystal field fluctuations is not only significant, but competitive with the effects of quantum fluctuations. Further, we argue that higher-multipolar interactions that are generically present in rare-earth magnets can dramatically enhance this effect. From a simplified bilinear-biquadratic model of these multipolar interactions, we show how the virtual crystal field fluctuations manifest in Er2Ti2O7 using a combination of strong coupling perturbation theory and the random phase approximation. We find that the experimentally observed psi2 state is indeed selected and the experimentally measured excitation gap can be reproduced when the bilinear and biquadratic couplings are comparable while maintaining agreement with the entire experimental spin-wave excitation spectrum. Finally, we comments on possible tests of this scenario and discuss implications for other order-by-disorder candidates in rare-earth magnets.

description: In this paper, we consider a general distributed estimation problem in relay-assisted sensor networks by taking into account time-varying asymmetric communications, fading channels and intermittent measurements. Motivated by centralized filtering algorithms, we propose a distributed innovation-based estimation algorithm by combining the measurement innovation (assimilation of new measurement) and local data innovation (incorporation of neighboring data). Our algorithm is fully distributed which does not need a fusion center. We establish theoretical results regarding asymptotic unbiasedness and consistency of the proposed algorithm. Specifically, in order to cope with time-varying asymmetric communications, we utilize an ordering technique and the generalized Perron complement to manipulate the first and second moment analyses in a tractable framework. Furthermore, we present a performance-oriented design of the proposed algorithm for energy-constrained networks based on the theoretical results. Simulation results corroborate the theoretical findings, thus demonstrating the effectiveness of the proposed algorithm.

How can young massive clusters reach their present-day sizes?

description: The classic question that how young massive star clusters attain their shapes and sizes, as we find them today, remains to be a challenge. Both observational and computational studies of star-forming massive molecular gas clouds infer that massive cluster formation is primarily triggered along the small-scale ($\lesssim0.3$ pc) filamentary substructures within the clouds. The present study is intended to investigate the possible ways in which a filament-like-compact, massive star cluster (effective radius 0.1-0.3 pc) can expand $\gtrsim10$ times, still remaining massive enough ($\gtrsim10^4 M_\odot$), to become a young massive star cluster, as we observe today. To that end, model massive clusters (of initially $10^4 M_\odot-10^5 M_\odot$) are evolved using Sverre Aarseth's state-of-the-art N-body code NBODY7. All the computed clusters expand with time, whose sizes (effective radii) are compared with those observed for young massive clusters, of age $\lesssim100$ Myr, in the Milky Way and other nearby galaxies. It is found that beginning from the above compact sizes, a star cluster cannot expand by its own, i.e., due to two-body relaxation, stellar-evolutionary mass loss, dynamical heating by primordial binaries and stellar-mass black holes, up to the observed sizes of young massive clusters; they always remain much more compact compared to the observed ones. This calls for additional mechanisms that can boost the expansion of a massive cluster after its assembly. Using further N-body calculations, it is shown that a substantial residual gas expulsion, with $\approx30$% star formation efficiency, can indeed swell the newborn embedded cluster adequately. The limitations of the present calculations and their consequences are discussed.

National Joint Registries and the United States
Creators: name: Fraser, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Background: On May 3, 2010 the Board of the American Joint Replacement Registry (AJRR) held its first meeting. After decades of debate and examination of existing joint registries, the American Academy of Orthopaedic Surgeons (AAOS) has recently determined that establishing the AJRR is a worthwhile project. This study will analyze the benefits and drawbacks of developing a national joint registry in the United States and will suggest the best design for the AJRR. Methods: In addition to conducting literature reviews of existing domestic and foreign joint registries, this study interviewed a variety of orthopaedic surgeons, including the chair of the AJRR, to gain unique perspectives on the future of an American joint registry. Results: Of 12 foreign national registries examined, 10 obtain the bulk of funding directly from the government, 9 are run by professional orthopaedic societies, and 6 mandate registry participation. Domestic joint registry proponents claim benefits of registries to include detecting poorly performing implants, gathering epidemiological data, and determining risk factors for bad outcomes. Major obstacles facing joint registries include the cost and burden of data collection and validation, encouraging surgeon participation, and determining what outcomes to measure. Conclusions: Barriers to the successful establishment of a national joint registry in the United States include the vast scale and cost of data collection and the need to appease all major stakeholders (surgeons, device manufacturers, hospitals, patients, payers, and government). If well-run, however, the AJRR could yield substantial benefits including the ability to detect poorly performing devices, gather epidemiological data, and ultimately improve the quality and value of total joint replacement. Clinical Relevance: The implementation of a national total joint registry in the US could have far-reaching influence on clinical orthopedics. In the short-term, registry data could be used to facilitate recalls of defective devices and identify risk factors for peri-operative complications. In the long-term, registry data could ultimately serve as a foundation for altering surgeon behaviors, limiting implant selection, and even determining which surgeons and hospitals should be performing total joint replacements.

description: The State of Illinois has had a well established Emergency Medical System disaster response plan since the 1970s. In the case of a wide spread event the readily available provider resources could be quickly depleted. The concept of an extended statewide medical emergency response was conceived in the mid- 1990s. IMERT (Illinois Medical Emergency Response Team) was established. While it is well respected and a role model for other states, the organization is not without inadequacies. This paper is an evaluation of the IMERT program to date.

description: The decorrelation in the azimuthal angle between the most forward and the most backward jets (Mueller-Navelet jets) is measured in data collected in pp collisions with the CMS detector at the LHC at sqrt(s) = 7 TeV. The measurement is presented in the form of distributions of azimuthal-angle differences, Delta(phi), between the Mueller-Navelet jets, the average cosines of (pi - Delta(phi)), 2(pi - Delta(phi)), and 3(pi - Delta(phi)), and ratios of these cosines. The jets are required to have transverse momenta, pT, in excess of 35 GeV and rapidities, |y|, of less than 4.7. The results are presented as a function of the rapidity separation, Delta(y), between the Mueller-Navelet jets, reaching Delta(y) up to 9.4 for the first time. The results are compared to predictions of various Monte Carlo event generators and to analytical predictions based on the DGLAP and BFKL parton evolution schemes.

Hispanic Participation in Cancer Support Groups: The Role of the Occupational and Environmental Health Nurse
Creators: name: Guevara, Enrique Henry, PhD, RN, COHN-S/CM
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: The occupational and environmental health nurse (OEHN) can play widely varied roles in assisting employees who have cancer. This paper explores those roles, particularly the possibilities for and barriers in referring Hispanic employees and their families to support groups or other resources. Hispanics’ barriers to using support groups include the lack of Spanish-speaking groups and the fact that Hispanics often rely on familial and spiritual-care groups instead of formal support groups. When considering Internet-based support groups, further barriers arise because of Hispanics’ traditionally limited access to computers and the Internet. The OEHN’s other roles in assisting an employee with cancer include a clinician, a case and disease manager, an educator, a researcher, a counselor, a consultant, and a facilitator for interdisciplinary interaction among a company’s human resources staff, management, legal department, and employee assistance department. Recommendations for the OEHN include the following: (a) use support groups to augment, not replace, other support mechanisms; (b) consider referral to an Internet-based support group on a case-by-case basis; (c) expect more use of face-to-face and Internet-based support groups with Hispanics as younger Hispanics, who are more familiar with computers, get older and cancer incidence rises among them.

description: Time series data on cropping pattern at disaggregated level were analysed and its implications on geospatial drought assessment were demonstrated. An index of Cropping Pattern Dissimilarity (CP-DI) between a pair of years, developed in this study, proved that the cropping pattern of a year has a higher degree of similarity with that of recent past years only and tends to be dissimilar with longer time difference. The temporal divergence in cropping pattern has direct implications on geospatial approach of drought assessment, in which, time series NDVI data are compared for drought interpretation. It was found that, seasonal NDVI profiles of drought year and normal year did not show any anomaly when the cropping patterns were dissimilar and two normal years having dissimilar cropping pattern showed different NDVI profiles. Therefore, it is suggested that such temporal comparisons of NDVI are better restricted to recent past years to achieve more objective interpretation.

description: The average white dwarf (WD) masses in cataclysmic variables (CVs) have been measured to significantly exceed those of single WDs, which is the opposite of what is theoretically expected. We present the results of binary population synthesis models taking into account consequential angular momentum loss (CAML) that is assumed to increase with decreasing WD mass. This approach can not only solve the WD mass problem, but also brings in agreement theoretical predictions and observations of the orbital period distribution and the space density of CVs. We speculate that frictional angular momentum loss following nova eruptions might cause such CAML and could thus be the missing ingredient of CV evolution.

Local subsystems in gauge theory and gravity

description: We consider the problem of defining localized subsystems in gauge theory and gravity. Such systems are associated to spacelike hypersurfaces with boundaries and provide the natural setting for studying entanglement entropy of regions of space. We present a general formalism to associate a gauge-invariant classical phase space to a spatial slice with boundary by introducing new degrees of freedom on the boundary. In Yang-Mills theory the new degrees of freedom are a choice of gauge on the boundary, transformations of which are generated by the normal component of the nonabelian electric field. In general relativity the new degrees of freedom are the location of a codimension-2 surface and a choice of conformal normal frame. These degrees of freedom transform under a group of surface symmetries, consisting of diffeomorphisms of the codimension-2 boundary, and position-dependent linear deformations of its normal plane. We find the observables which generate these symmetries, consisting of the conformal normal metric and curvature of the normal connection. We discuss the implications for the problem of defining entanglement entropy in quantum gravity. Our work suggests that the Bekenstein-Hawking entropy may arise from the different ways of gluing together two partial Cauchy surfaces at a cross-section of the horizon.

A Program Model for Latino Family Support Services at the University of North Carolina Craniofacial Center
Creators: name: Cook, Anne Bouchelle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Latino patients face many challenges when seeking health care because of sociocultural, financial, and language barriers, which influence the overall level of support for a family within and outside of the health care system. At the University of North Carolina Craniofacial Center (UNC CFC), Latino families have identified a desire to connect with other Latino parents who have children with craniofacial differences and have also requested improvements in the Spanish craniofacial educational materials. The provision of these supports, in theory, will augment the Latino's ability to successfully coordinate and cope with their child's care. This paper designs a program plan and an evaluation plan for social and informational support services for the Latino patient families seen at the UNC CFC. The program includes the implementation of a bimonthly Spanish-speaking support group and the utilization of services through the Family Support Network of North Carolina to increase social support and subsequent volunteering of Latino families. To increase the informational support for the families, the program includes planned viewing times for a Spanish cleft lip and/or palate video as well as provision of Spanish craniofacial booklets manufactured by the Cleft Palate Foundation. An initial assessment of the program will include a qualitative evaluation of the implementation of the program, and will include examination of records of service utilization and Latino parent focus groups. Future evaluations of longer-term outcomes will include pre- and post- intervention surveys of the Latino parents receiving the services, and informal interviews with UNC CFC staff members. If this project successfully creates a supportive social and educational environment for the parents and families of Latino patients, it can serve as a model for culturally appropriate support programs to be implemented within other fields in health care.

The Effect of HIV Public Health Marketing Campaigns on Linkage to Care: Can Advertisements Encourage Individuals to go to a Medical Clinic for HIV testing and/or HIV care?
Creators: name: Watkins, Holly
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: BACKGROUND: In recent years, North Carolina has averaged approximately 1,400 - 1,500 new HIV reports annually and a majority of those new cases are among African-Americans. Approximately 30 percent of the individuals newly reported each year with HIV disease also represents new AIDS cases. This significant proportion of late diagnoses (i.e. AIDS) indicates the need for increased HIV testing, education and linkage to care in North Carolina. OBJECTIVE: This paper describes how HIV affects North Carolinians and examines the link between public health marketing campaigns and linking HIV positive patients to HIV care and treatment. METHOD: A public health marketing campaign that includes advertisements on television stations and specific web sites will be available at given times throughout the calendar year. The advertisements will include a specific call to action (either a web site address or phone number to get more information) which can be measured an evaluated to determine if the individual gets further information about getting tested for HIV and/or get into HIV care. RESULTS: A marketing campaign using television commercials was launched in June 2012. The television commercials aired during three separate time periods: June 2012 - August 2012, December 2012 - February 2012 and January 2013 - May 29, 2013. Results from that campaign showed that 54 individuals called to get more information on getting tested for HIV or getting into care for HIV. 32 of those individuals were linked to HIV care and medications. CONCLUSIONS: This campaign taught us valuable lessons, including the importance of using not only television, but expanding to the use of web sites. Many of the individuals that we want to reach use the internet as the primary means of getting information, meeting people and communication. The question then becomes, "Can advertisements encourage people to get tested for HIV or motivate them to get into care if they are HIV positive?"

We solve the problem of optimal allocation of observations under the measurement budget constrain for two types of sets, ellipsoids and hyperrectangles. By elaborating on the two examples of Sobolev ellipsoids and hyperectangles, we demonstrate how re-allocating the measurements in the (sub-)optimal way improves on the standard uniform allocation. In particular, we improve the famous Pinsker (1980) bound.

description: Magneto-transport measurements of Shubnikov-de Haas (SdH) oscillations have been performed on two-dimensional electron gases (2DEGs) confined in CdTe and CdMnTe quantum wells. The quantum oscillations in CdMnTe, where the 2DEG interacts with magnetic Mn ions, can be described by incorporating the electron-Mn exchange interaction into the traditional Lifshitz-Kosevich formalism. The modified spin splitting leads to characteristic beating pattern in the SdH oscillations, the study of which indicates the formation of Mn clusters resulting in direct anti-ferromagnetic Mn-Mn interaction. The Landau level broadening in this system shows a peculiar decrease with increasing temperature, which could be related to statistical fluctuations of the Mn concentration.

Two Roads to Providing the HPV Vaccine: a United States-United Kingdom Comparative Analysis of Adopting and Allocating a Preventive Therapy

description: Vaccinating populations against a common cancer seems like a public health and health outcomes miracle, but that is the hope of those who have worked to develop and disseminate a human papilloma virus (HPV) vaccine. The United States Food and Drug Administration (FDA) and the United Kingdom Joint Committee on Vaccination and Immunisation (JCVI) approved a new HPV vaccine, Gardasil, in 2006 and 2007 respectively. The vaccine's approval is a substantial and still unfolding event in both systems' health services, health care quality, and public health outcomes arenas. The vaccine has the potential to cost and possibly to save billions of health care dollars, to save millions of people from contracting sexually transmitted HPV infections, and to prevent thousands of women from developing cervical cancer annually. This research compares and contrasts the response to the new HPV vaccine by the health systems and political environments in the United States and the United Kingdom.

description: Hydrochloric acid (HCl) leaching process plays a significant role in energy-critical elements extraction industry. In this thesis, a low-emission process integrating CO2 capture with SiO2-assisted pyro-hydrolysis was developed for regenerating valuable HCl from CaCl2 waste. The feasibility of this process was comprehensive investigated from techno-economic, thermodynamic, and kinetic aspects. To achieve this, both experimental approach and simulation approach including flowsheet simulation, density functional theory calculation, were employed in this thesis. These findings provide valuable support for the advancement of HCl regeneration technology and make a significant contribution to the circular economy and sustainable development of the HCl-based critical elements extraction industry.

Program Plan and Evaluation for the Skin Cancer Prevention Initiative: A Collaborative Skin Cancer Prevention Program for Transplant Recipients at the University of North Carolina
Creators: name: Moye, Virginia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Due to the use of long-term immunosuppressive therapy required to prevent transplant rejection, solid organ transplant recipients are at extremely elevated risk of developing skin cancer. Squamous cell carcinoma of the skin is 65- to 200-times more common among transplant recipients than in the general population. It is exceptionally aggressive, with a rate of metastasis of ~7%. Sun exposure is a major modifiable risk factor for the development of skin cancer. Nonetheless, previous research has established that many transplant recipients are unaware of their increased risk of skin cancer and the value of sun protection. As a result, prevention programs targeting sun exposure have the potential to lengthen and improve quality of life for many of these individuals. This paper outlines a program and evaluation plan for the Skin Cancer Prevention Initiative, a skin cancer prevention program for transplant recipients at the University of North Carolina. By establishing a strong collaboration between UNC’s transplant clinics and Department of Dermatology, the program seeks to reduce the burden of suffering due to skin cancer among UNC’s transplant population. Key aspects of the program include (a) emphasis on patient education, (b) a streamlined dermatology referral process, (c) individualized risk assessment, and (d) provision of free or discounted sunscreen and wide brim hats to transplant recipients.
