description: We present an energy dependent X-ray variability study of the 2010 outburst of the black hole X-ray binary MAXI J1659-152 with the Swift X-ray Telescope (XRT). The broad-band noise components and the quasi periodic oscillations (QPO) observed in the power spectra show a strong and varied energy dependence. Combining Swift XRT data with data from the Rossi X-ray Timing Explorer, we report, for the first time, an rms spectrum (fractional rms amplitude as a function of energy) of these components in the 0.5-30 keV energy range. We find that the strength of the low-frequency component (< 0.1 Hz) decreases with energy, contrary to the higher frequency components (> 0.1 Hz) whose strengths increase with energy. In the context of the propagating fluctuations model for X-ray variability, we suggest that the low-frequency component originates in the accretion disk (which dominates emission below ~ 2 keV) and the higher frequency components are formed in the hot flow (which dominates emission above ~ 2 keV). As the properties of the QPO suggest that it may have a different driving mechanism, we investigate the Lense-Thirring precession of the hot flow as a candidate model. We also report on the QPO coherence evolution for the first time in the energy band below 2 keV. While there are strong indications that the QPO is less coherent at energies below 2 keV than above 2 keV, the coherence increases with intensity similar to what is observed at energies above 2 keV in other black-hole X-ray binaries.

description: How complex organic - and potentially prebiotic - molecules are formed in regions of low- and high-mass star-formation remains a central question in astrochemistry. In particular, with just a few sources studied in detail, it is unclear what role environment plays in complex molecule formation. In this light, a comparison of relative abundances of related species between sources might be useful to explain observed differences. We seek to measure the relative abundance between three important complex organic molecules, ethylene glycol ((CH$_2$OH)$_2$), glycolaldehyde (CH$_2$OHCHO) and methyl formate (HCOOCH$_3$), toward high-mass protostars and thereby provide additional constraints on their formation pathways. We use IRAM 30-m single dish observations of the three species toward two high-mass star-forming regions - W51/e2 and G34.3+0.2 - and report a tentative detection of (CH2OH)2 toward both sources. Assuming that (CH$_2$OH)$_2$, CH$_2$OHCHO and HCOOCH$_3$ spatially coexist, relative abundance ratios, HCOOCH$_3$/(CH$_2$OH)$_2$, of 31 and 35 are derived for G34.3+0.2 and W51/e2, respectively. CH$_2$OHCHO is not detected, but the data provide lower limits to the HCOOCH$_3$/CH$_2$OHCHO abundance ratios of $\ge$193 for G34.3+0.2 and $\ge$550 for W51/e2. A comparison of these results to measurements from various sources in the literature indicates that the source luminosities may be correlated with the HCOOCH$_3$/(CH$_2$OH)$_2$ and HCOOCH$_3$/CH$_2$OHCHO ratios. This apparent correlation may be a consequence of the relative timescales each source spend at different temperatures-ranges in their evolution. Furthermore, we obtain lower limits to the ratio of (CH$_2$OH)$_2$/CH2OHCHO for G34.3+0.2 ($\ge$6) and W51/e2 ($\ge$16). This result confirms that a high (CH$_2$OH)$_2$/CH$_2$OHCHO abundance ratio is not a specific property of comets, as previously speculated.

description: It was recently proposed that weakly interacting massive particles (WIMP) may provide new ways of generating the observed baryon asymmetry in the early universe, as well as addressing the cosmic coincidence between dark matter and baryon abundances. This suggests a new possible connection between weak scale new particle physics and modern cosmology. This review summarizes the general ideas and simple model examples of the two recently proposed WIMP baryogenesis mechanisms: baryogenesis from WIMP dark matter annihilation during thermal freezeout, and baryogenesis from metastable WIMP decay after thermal freezeout. This letter also discusses the interesting phenomenology of these models, in particular the experimental signals that can be probed in the intensity frontier experiments and the Large Hadron Collider (LHC) experiments.

Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: The outputs of non-linear feed-forward neural network are positive, which could be treated as probability when they are normalized to one. If we take Entropy-Based Principle into consideration, the outputs for each sample could be represented as the distribution of this sample for different clusters. Entropy-Based Principle is the principle with which we could estimate the unknown distribution under some limited conditions. As this paper defines two processes in Feed-Forward Neural Network, our limited condition is the abstracted features of samples which are worked out in the abstraction process. And the final outputs are the probability distribution for different clusters in the clustering process. As Entropy-Based Principle is considered into the feed-forward neural network, a clustering method is born. We have conducted some experiments on six open UCI datasets, comparing with a few baselines and applied purity as the measurement . The results illustrate that our method outperforms all the other baselines that are most popular clustering methods.

description: We derive the general counting rules for a quantum effective field theory (EFT) in $\mathsf{d}$ dimensions. The rules are valid for strongly and weakly coupled theories, and predict that all kinetic energy terms are canonically normalized. They determine the energy dependence of scattering cross sections in the range of validity of the EFT expansion. We show that the size of cross sections is controlled by the $Λ$ power counting of EFT, not by chiral counting, even for chiral perturbation theory ($χ$PT). The relation between $Λ$ and $f$ is generalized to $\mathsf{d}$ dimensions. We show that the naive dimensional analysis $4π$ counting is related to $\hbar$ counting. The EFT counting rules are applied to $χ$PT, low-energy weak interactions, Standard Model EFT and the non-trivial case of Higgs EFT.

description: We present observations of Swift J1112.2-8238, and identify it as a candidate relativistic tidal disruption flare (rTDF). The outburst was first detected by Swift/BAT in June 2011 as an unknown, long-lived (order of days) $γ$-ray transient source. We show that its position is consistent with the nucleus of a faint galaxy for which we establish a likely redshift of $z=0.89$ based on a single emission line that we interpret as the blended [OII]$\lambda3727$ doublet. At this redshift, the peak X/$γ$-ray luminosity exceeded $10^{47}$ ergs s$^{-1}$, while a spatially coincident optical transient source had $i^{\prime} \sim 22$ (M$_g \sim -21.4$ at $z=0.89$) during early observations, $\sim 20$ days after the Swift trigger. These properties place Swift J1112.2-8238 in a very similar region of parameter space to the two previously identified members of this class, Swift J1644+57 and Swift J2058+0516. As with those events the high-energy emission shows evidence for variability over the first few days, while late time observations, almost 3 years post-outburst, demonstrate that it has now switched off. Swift J1112.2-8238 brings the total number of such events observed by Swift to three, interestingly all detected by Swift over a $\sim$3 month period ($<3\%$ of its total lifetime as of March 2015). While this suggests the possibility that further examples may be uncovered by detailed searches of the BAT archives, the lack of any prime candidates in the years since 2011 means these events are undoubtedly rare.

Drug Courts in Vermont: Would the integration of Methadone Maintenance Therapy (MMT) in treatment protocols reduce recidivism among heroin using offenders?
Creators: name: Fisher, Terry
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Vermont is often thought of as a peaceful, bucolic place, steeped in tradition and rural appeal. Although this picture is accurate, it fails to account for the overall changes occurring in Vermont. Vermont is a predominately rural state with a fairly homogenous population of I- 619,107 (U.S. Census Bureau, 2003). The state's largest community, Burlington, hosts over 150,000 members of this population and is the only community with a metropolitan status by U.S. Census Bureau standards. With a density of 65 persons/square mile (U.S. Census Bureau, Quickfacts, 2003), Vermont is quite rural by most measures. However, even in this rural haven of dairy farms and activist ice cream businesses, the use and abuse of heroin is rising dramatically.

Assessment of Formal Program Planning at the North Carolina Division of Public Health
Creators: name: Ervin, Claire M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: This paper examines the program planning processes employed at the North Carolina Division of Public Health (NCDPH). Through the use of a sixtyfour question Likert-scale survey, two major research questions were addressed: 1) How often do program planners employ certain elements of formal program planning; 2) How important program planners feel those elements of program planning are. Findings from the survey suggest that formal program planning is not occurring with regularity, even though program planners believe that formal program planning is important. The results of this survey were then coupled with prior research conducted on the same population regarding the barriers and facilitators to performing formal program planning. By merging these data, the researcher was able to make certain inferences as to why certain program planning elements were occurring with greater frequency than others. These data also provided the necessary information to develop the foundation for initial interventions to improve the formal program planning processes at the NCDPH. Two interventions are suggested as a result ofthis survey.

description: We report the observation and the theoretical explanation of the parametric down-conversion nonlinear susceptibility at the $K$-absorption edge of diamond and at the $L_{23}$-absorption edge of a silicon crystal. Using arguments similar to those invoked to successfully predict resonant inelastic x-ray spectra, we derive an expression for the renormalization term of the non-linear susceptibility at the x-ray edges, which can be evaluated by using first-principles calculations of the atomic scattering factor $f_1$. Our model is shown to reproduce the observed enhancement of the parametric down-conversion at the diamond $K$ and the Si $L_{23}$ edges rather than the suppression previously claimed.

Using the Transtheoretical Model to address Member Retention rates at the ViQuest Center, a medically modeled wellness center
Creators: name: Simmons, Rose Ann
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Physical Inactivity is a major public health issue facing America. The issue of inactivity led to the release of the Surgeon Generals Report on Physical Activity and Health in 1996. The report was the first of its kind to bring together numerous studies on the health benefits of physical activity and exercise. The report contributed to a revolution in the fitness industry, with 11.2 million memberships being sold in 1997. However, member retention is a challenge for the fitness industry, including the ViQuest Center. A majority of individuals discontinue their memberships due to controllable factors such as no time, too busy or not using. The underlying issue relates to their behavior. These individuals have been unsuccessful at achieving a physically active lifestyle. Behavior modification programs have been used to assist people in achieving healthy behaviors. The Transtheoretical Model is one approach that can be used to identify an individuals' motivation to change and assist them in making a healthy behavior a reality. It is expected that health clubs, including the ViQuest Center, that institute a behavior modification program at the time of initial membership will be able to increase their member retention numbers and save money.

description: Precise measurements of the baryon acoustic oscillation (BAO) scale as a standard ruler in the clustering pattern of large-scale structure is a central goal of current and future galaxy surveys. The BAO peak may be sharpened using the technique of density-field reconstruction, in which the bulk displacements of galaxies are estimated using a Zel'dovitch approximation. We use numerical simulations to demonstrate how the accuracy of this approximation depends strongly on local environment, and how this information may be used to construct an improved BAO measurement through environmental re-weighting and using higher-order perturbation theory. We outline further applications of the displacement field for testing cosmological models.

description: A set of views defined by selection queries splits a database relation into sub-relations, each containing a subset of the original rows. This decomposition into horizontal fragments is lossless when the initial relation can be reconstructed from the fragments by union. In this paper, we consider horizontal decomposition in a setting where some of the attributes in the database schema are interpreted over a specific domain, on which a set of special predicates and functions is defined. We study losslessness in the presence of integrity constraints on the database schema. We consider the class of conditional domain constraints (CDCs), which restrict the values that the interpreted attributes may take whenever a certain condition holds on the non-interpreted ones, and investigate lossless horizontal decomposition under CDCs in isolation, as well as in combination with functional and unary inclusion dependencies.

Public Health and the Incident Command System: A Shift From Disasters To Every Day Management
Creators: name: Ray, William C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: The organizational structure of a public health agency can directly affect the success or failure of its programs. Currently within public health, quality improvement initiatives are being undertaken in order to improve the provision of services and response to the needs of the public. As a part of the identification of areas for improvement, the assessment of the organizational structure of the public health entity needs to become an integral part of that process. The current needs and challenges that public health entities confront are expanding and changing. The services, projects, and programs that local health departments are responsible for are varied and broad. Those entities need an organizational structure that allows for an efficient and effective response to those broad needs. The Incident Command System (ICS) is an organizational structure that will facilitate the most effective and efficient response to everyday needs or issues that arise from a sudden disaster. The ICS is currently utilized mainly in response to disasters. The features detailed in this paper, along with case studies of ICS use, will support the proposal that the ICS is an effective organizational structure for every day management of a public health entity. The foundations and boundaries that the ICS establishes allows all types of organizations—hospitals, veterinary clinics, local health departments (LHD), etc.—to tailor the structure to meet the specific needs and mission of the organization. It allows for response to the broad range of needs that public health entities see daily. When a disaster does occur, the structure is already in place to respond and valuable time and resources are not lost in the transition. Personnel education and training about the ICS is vital. To ensure effective management and operation within the structure, as well as support from involved personnel, education is incredibly important. Quality improvement initiatives have allowed for LHDs to improve 2 services and organizational function. The use of an ICS structure will complement and greatly facilitate CQI initiatives.

Intraprostatic Injection of Absolute Ethanol or Botulinum Toxin as a Treatment for Benign Prostatic Hyperplasia: A Systematic Review of the Literature
Creators: name: McKim, Stephen Ernest
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: INTRODUCTION: Benign prostatic hyperplasia (BPH) is a highly prevalent disease that inflicts significant inconvenience upon men afflicted with it and, if left untreated, can progress to complete obstruction resulting in uremia and kidney failure. The purpose of this paper is to systematically review the published evidence regarding the use of two injectable agents, botulinum toxin (BT) and absolute ethanol (AE), used intraprostatically and to assess their effectiveness as a potential minimally invasive treatment for benign prostatic hyperplasia. METHODS: A comprehensive literature search of several databases including MEDLINE was performed, and articles were selected based on their fitting predefined inclusion and exclusion criteria. These studies were evaluated based on four research questions examining the efficacy of the treatment in relieving subjective and objective elements of BPH, its safety, and comparisons with traditional treatment options. RESULTS: A total of five studies using BT and six using AE was selected for inclusion in the review. The studies varied significantly in the quality of their design and implementation. Subjective relief of the BPH symptoms was measured in every study, while resolution of the different objective signs of BPH was measured to a varying degree in each study. Very few significant safety issues were reported in any of these studies. No study using either agent directly compared the therapeutic effects of intraprostatic injection to a traditional therapy for BPH. CONCLUSIONS: Published studies indicate that intraprostatic injection of AE and BT are safe and effective treatments for BPH. Whether these treatments are superior to traditional interventions for BPH in efficacy or cost remains to be determined, and before this treatment modality can be recommended for use in routine practice, blinded, high quality, controlled randomized trials testing them must be performed.

description: The dispersion of the star-formation main sequence (SFMS) reflects the diversity of star formation histories and variation in star formation rates (SFRs) in star-forming galaxies (SFGs) with similar stellar masses ($M^\ast$). We examine the dispersion of local SFMS using a complete sample of Sloan Digital Sky Survey galaxies at 0.01$$8.8. The SFRs are estimated from H$α$ in combination with 22$μm$ observation from WISE. The catalog of bulge+disk decomposition from Simard et al. (2011) is available for the sample galaxies. We measure the dispersion of specific SFR (SSFR) as a function of $M^*$. We confirm that the dispersion increases with $M^*$ from 0.37$\pm0.01$dex at $\log(M^\ast/M_\odot)$10.2. Despite star formation is mostly associated with disks, the dispersion of disk SSFR still increases with $M^*$. We conclude that the presence of bulges/bars is likely responsible for the large dispersion of SSFR in massive SFGs while low-mass SFGs are mostly disk-dominated and thus with small dispersion. Our results suggest that star formation on galactic scales is dramatically affected by central dense structures through both enhancing and/or quenching processes; while lower-mass SFGs tend to have less bursty star formation histories. However, the dispersion of SSFR becomes significantly smaller and remains constant when only disk-dominated SFGs are counted. This finding implies that the impact of stochastic stellar feedback on star formation is likely to follow the same pattern in all disk galaxies, showing no correlation with halo potential.

description: Background: Colorectal cancer is the third most common neoplasm in the United States, with over 150,000 people receiving a new diagnosis every year. Colorectal cancer is also the second-leading cause of all cancer-associated mortality, attributed to deaths totaling nearly 50,000 annually. Despite the morbidity and mortality of colorectal cancer and the effectiveness early detection, colorectal cancer screening lags behind other types of screening. Patient education and health literacy are posited to play a role in the lack of colorectal cancer screening in American adults. Purpose: To evaluate the effectiveness of patient-oriented educational materials, including small media and decision aids on the outcomes of screening uptake, patient knowledge, and patient intent. Data Sources: MEDLINE, CINAHL, hand-searched reference list Study Selection: One reviewer independently selected studies addressing the study questions and met eligibility criteria. Data Extraction: Information on study design, setting, intervention, comparators, study population, outcomes, and quality were extracted by one reviewer. The reviewer assigned a quality rating for each study. Data Synthesis: The reviewer found that with regards to increasing colorectal cancer screening uptake, the evidence is mixed, with two studies demonstrating the a positive effect, three demonstrating no effect, and one showing a negative effect. All three studies investigating patient knowledge suggest an increase in knowledge. Patient intent for screening was mixed, with one study showing a positive effect, one showing a negative effect and two showing no effects at all. Limitations Only investigated randomized controlled trials as opposed to pre-post test interventions. Articles used different measurement tools/methods for assessing outcomes of interest. Limited the number of outcomes to only three. Investigated only educational materials while excluding other interventions. Conclusion: Evidence is mixed regarding the effectiveness of patient-directed educational interventions on CRC screening uptake. More evidence and standardization of outcomes/methods and educational content are needed in order to assess patient intent and uptake of screening. Nevertheless, patient educational materials are effective at improving patient knowledge, important especially when informed consent and informed decision-making are goals for appropriate care.
Duality and deformations of stable Grothendieck polynomials

description: Stable Grothendieck polynomials can be viewed as a K-theory analog of Schur polynomials. We extend stable Grothendieck polynomials to a two-parameter version, which we call canonical stable Grothendieck functions. These functions have the same structure constants (with scaling) as stable Grothendieck polynomials, and (composing with parameter switching) are self-dual under the standard involutive ring automorphism. We study various properties of these functions, including combinatorial formulas, Schur expansions, Jacobi-Trudi type identities, and associated Fomin-Greene operators.

A Model for Remote Ischemic Conditioning in Prehospital ST-Elevation Myocardial Infarction Patients: A Systematic Review
Creators: name: Quigley, Benjamin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Acute myocardial infarction is treated regularly with emergency coronary intervention, but this treatment comes with the risk of reperfusion injury. Remote ischemic conditioning (RIC) is a treatment that has the potential to reduce the impact of reperfusion injury, but it is unclear what effect it has on patients diagnosed with ST-elevation myocardial infarction (STEMI) when used before cardiac intervention. This systematic review was performed to identify and evaluate studies that assess whether RIC improves mortality, reduces myocardial injury, and leads to better clinical outcomes when used in patients at risk for reperfusion injury. Searches were performed in PubMed, EMBASE, and ClinicalTrials.gov through April 2018 for clinical trials comparing RIC and standard care before patients with STEMI receive ether percutaneous coronary intervention (PCI) or thrombolytic intervention. Outcomes considered in this review include all-cause mortality, infarct size, ST-segment resolution, cardiac biomarker trends, left ventricular ejection fraction, and myocardial salvage index. One investigator selected qualifying trials, extracted data, and assessed the strength of evidence.Eleven studies (2,981 participants) were included in this review and most were found to demonstrate a low risk of bias. Evidence was found to be of moderate strength for four outcomes (all-cause mortality, infarct size, left ventricular ejection fraction, and myocardial salvage index), low strength for one outcome (ST-segment resolution), and very low strength for one outcome (cardiac biomarker trends). All-cause mortality was the only outcome for which the evidence showed no difference between RIC and standard care. Significant decreases in infarct size, when measured directly through imaging, was moderate, ranging from 2% to 6.5%, but varied widely when infarct size was measured using ST-segment resolution and cardiac biomarker trends as proxies. Myocardial salvage index was consistently shown to be improved in RIC patients but varied in magnitude from 8.7% to 50% higher median index scores. Most studies found higher left ventricular ejection fractions with magnitudes ranging from 2.6% to 10%. The evidence synthesized here shows that RIC improves intermediate cardiac outcomes but has not been shown to improve all-cause mortality.

Functional Capacity in Men and Women Following Cardiac Rehabilitation
Creators: name: Gee, Michael

description: Nearly one in three Americans suffers from cardiovascular disease (CVD), which is responsible for over 850,000 U.S. deaths each year. Cardiac rehabilitation (CR) is an effective treatment for CVD; CR involves multifaceted interventions of supervised exercise, dietary modifications, and counseling. Based on previous research, which is confirmed by this paper’s systematic review, CR is effective at improving patients’ functional capacity. Although women represent over half of CVD patients, there is surprisingly little known about the comparative effectiveness of CR in men and women. This master’s paper seeks to determine whether CR is equally effective at improving functional capacity, as determined by maximal metabolic equivalents (METs) achieved in men and women. The research is based upon data between 2001 to 2011 from the University of North Carolina health Care Cardiac Rehabilitation Program at Meadowmont. Based on de-identified records from 680 CR participants (189 women; 491 men), CR does seem to be somewhat more effective in men than in women. Specifically, adjusting for potential confounders, men achieved an average improvement of 2.15 METs after CR and women achieved an average improvement of 1.61 METs. It is unclear why men benefit more from CR than do women; these results, however, imply that tailoring cardiac rehabilitation programs to women may yield further improvement in functional capacity for female participants.
