description: This is a pre-registration for the study "Considerations for Retaining Challenging Longitudinal Samples: Mental Health Symptoms and Contact Methods as Predictors of Retention among a Sample of Repeat and First-Time DUI Offenders". This study will examine whether psychiatric comorbidity is associated with levels of attrition and amount of effort required for follow-up in a sample of repeat and first-time DUI offenders. It also aims to determine how much contact is needed and which methods of contact are most effective in reaching this population. The attached pre-registration provides detailed information about the data set, sample, design, and analytic plans for this study.

description: The Kepler mission's discovery of a number of circumbinary planets orbiting close (a_p < 1.1 au) to the stellar binary raises questions as to how these planets could have formed given the intense gravitational perturbations the dual stars impart on the disk. The gas component of circumbinary protoplanetary disks is perturbed in a similar manner to the solid, planetesimal dominated counterpart, although the mechanism by which disk eccentricity originates differs. This is the first work of a series that aims to investigate the conditions for planet formation in circumbinary protoplanetary disks. We present a number of hydrodynamical simulations that explore the response of gas disks around two observed binary systems: Kepler-16 and Kepler-34. We probe the importance of disk viscosity, aspect-ratio, inner boundary condition, initial surface density gradient, and self-gravity on the dynamical evolution of the disk, as well as its quasi steady-state profile. We find there is a strong influence of binary type on the mean disk eccentricity, e_d, leading to e_d = 0.02 - 0.08 for Kepler-16 and e_d = 0.10 - 0.15 in Kepler-34. The value of alpha-viscosity has little influence on the disk, but we find a strong increase in mean disk eccentricity with increasing aspect-ratio due to wave propagation effects. The choice of inner boundary condition only has a small effect on the surface density and eccentricity of the disk. Our primary finding is that including disk self-gravity has little impact on the evolution or final state of the disk for disks with masses less than 12.5 times that of the minimum-mass solar nebula. This finding contrasts with the results of self-gravity relevance in circumprimary disks, where its inclusion is found to be an important factor in describing the disk evolution.

description: Stationary density waves rotating at a constant pattern speed $Ω_{\rm P}$ would produce age gradients across spiral arms. We test whether such age gradients are present in M81 by deriving the recent star formation histories (SFHs) of 20 regions around one of M81's grand-design spiral arms. For each region, we use resolved stellar populations to determine the SFH by modeling the observed color-magnitude diagram (CMD) constructed from archival Hubble Space Telescope (HST) F435W and F606W imaging. Although we should be able to detect systematic time delays in our spatially-resolved SFHs, we find no evidence of star formation propagation across the spiral arm. Our data therefore provide no convincing evidence for a stationary density wave with a single pattern speed in M81, and instead favor the scenario of kinematic spiral patterns that are likely driven by tidal interactions with the companion galaxies M82 and NGC 3077.

description: The present work aimed to study the chemical composition and bioactivity of the leaf essential oil of Cupressus sempervirens L. and Cupressus lusitanica Mill. (Cupressaceae) on mycelial growth and germination of Colletotrichum fructicola conidia at the essential oil concentrations of 0.1, 0.5, 1.0, 1.5, and 2.0 µL·mL−1. The essential oil of C. sempervirens presented β-thujene as the major compound (31.4 wt.%), whereas C. lusitanica essential oil was composed mainly of α-pinene (22.7 wt.%). The bioactivity tests showed that both essential oils were ineffective in controlling adult C. fructicola individuals at the tested doses. However, antifungal activity of the oils against germination of the conidia was observed, in which C. sempervirens and C. lusitanica essential oils inhibited 50 % and 38 % of C. fructicola conidia germination at the concentration of 2 µL·mL−1. Morphological alterations of hyphae were also observed after exposure to C. sempervirens essential oil at the dose of 2 µL·mL−1.

Year: 2019

description: This study looked at possible hazard mitigation options that can be implemented in Princeville, North Carolina. Having faced numerous extreme flooding events in the past few decades, the town is currently susceptible to further damage. The town flooded for various reasons, including the lack of proper structural mitigation measures currently in place. Based on the recommended mitigation measures brought forth by the North Carolina Emergency Management, this study evaluated three of their approaches using case studies: 1) Buyouts, 2) Town Relocation, and 3) Structural Elevation. The case study towns had previously implemented these mitigation practices post-disasters, and they were evaluated on their applicability to Princeville. To determine the best fit mitigation strategy for Princeville, a policy evaluation framework was used. The evaluation criterion has 5 parts: 1) Effectiveness, 2) Efficiency, 3) Flexibility, 4) Equity, and 5) feasibility. This study found that the best mitigation strategy to be applied to Princeville is a combination of buyouts and town relocation that will focus on the most flood-prone areas first. These strategies will also be used to preserve the cultural and historical history of Princeville.

description: For wound healing, angiogenesis is one of the main therapeutic factors for recovering the injured tissue. To address this issue, a combination of two different polymers, alginate (ALG) and hyaluronic acid (HA) in an 80:20 ratio composition is used to optimize the bead system along with the 5 IU heparin (Hep) by crosslinking into calcium chloride (CaCl2). Encapsulation of Vascular endothelial growth factor (VEGF) in the bead system shows delayed cumulative release in phosphate buffer saline (PBS). For in vitro studies, calf pulmonary artery endothelial (CPAE) cells showed biocompatibility. ALG–HA/VEGF150 improves endothelial Vascular cell adhesion protein 1 (VCAM1) and endothelial nitric oxide synthase (eNOS) expression markers in CPAE cells. In vivo evaluation of the bead system shows around 68% of wound closure 2 weeks post-implantation in 8 mm punch wound models. The treatment group shows decreased epithelial gap between the ends of the wound and neo-epidermal regeneration. ALG–HA/VEGF150 induced significant vascularization, collagen type-1 (Col-1) and fibronectin (FN) development in the in vivo models after 2 weeks of the implantation. Hence, ALG–HA/VEGF150 beads can be used to promote wound healing. Schematic workflow diagram including in vitro and in vivo results.

description: This document was created to serve as a framing document for the development of an Equity Plan for Dorothea Dix Park. The call for an Equity Plan originated from the Master Planning Advisory Committee as a next steps action item following the adoption of the Dix Park Master Plan. To aid in the development of this Equity Plan, this framework will serve multiple purposes. First, a brief summary of the site’s history will be given, with additional focus on landscape uses and sensitive themes that have resulted from the site’s development. Second, a summary of the planning process to date will be given, with a focus on community outreach and engagement efforts. Third, a review of relevant literature will answer the following questions: 1) What is an equity plan?; 2) What is the Park Equity Movement?; 3) What are some comparable plans that can inform the creation of the Dix Park Equity Plan. Fourth and finally, project details that will aid in crafting the Equity Plan will be provided, including recommendations in the areas of process, potential partner organizations, and equity dimensions. These sections combine to provide a base of knowledge that will aid in the speed and thoroughness of the creation of the Dix Park Equity Plan.

description: Temperature and oxidation-sensitive liposomes were prepared by stabilizing dioleoylphosphatidylethanolamine (DOPE) bilayers with the ion pair of poly(ethyleneimine)/(phenylthio)acetic acid (PEI/PTA). An upper critical solution temperature (UCST) behavior was observed when PEI/PTA ion pair was suspended in an aqueous solution. It was observed that the UCST increased with increasing PTA content. The ion pair was self-assembled into nanospheres owing to its amphiphilic property which was confirmed by transmission electron microscopy. The FT-IR spectroscopic spectrum showed that the ion pair formed a salt bridge between the amino group and the carboxyl group and the PTA content in the ion pair was readily oxidized by H2O2. Further, DOPE liposomal membranes could be stabilized with PEI/PTA ion pair. Due to the amphiphilic property, the ion pair played a role as a stabilizer for the formation of DOPE liposomes. The liposome released its payload in a temperature-responsive manner, possibly because when the temperature is raised, the ion pair loses its amphiphilic property and can be detached from the liposomal membrane. The liposome was also oxidation-responsive in terms of release, possibly because the amphiphilic property of the ion pair disappears when the PTA is oxidized. The schematic diagram of temperature and oxidation-sensitive DOPE liposome incorporating PEI/PTA ion pair.

description: Transurethral resection of the prostate (TURP) is the standard surgical treatment for benign prostate enlargement (BPE). Photoselective vaporization of the prostate (PVP) is an alternative, but there is limited real-life evidence of PVP risks. To compare short- and long-term risks of PVP to those of TURP in the treatment of BPE. Consecutive patients who underwent elective PVP or TURP between 2006 and 2018 in 20 hospitals in Finland were retrospectively studied using a combination of national registries (n = 27,408; mean age 71 years). Short-term risks were postoperative mortality, major adverse cardiovascular events (MACE), and reoperations for bleeding. Long-term risks were reoperations for BPE or any urethral operations within 12 years. Differences between treatment groups were balanced by inverse probability of treatment weighting. Risks were analyzed using the Kaplan–Meier method and Cox regression. There were no differences in postoperative mortality or MACE between the study groups. Reoperations for bleeding were less frequent after PVP (0.9%, HR: 0.72, p = 0.042). Bleeding was more likely in patients with atrial fibrillation (number needed to treat [NNT] for PVP vs TURP: 61). Cumulative incidence for reoperation was higher after PVP (23.5%) than after TURP in long-term follow-up (17.8%; HR: 1.20, p < 0.0001, NNT: −31.7). PVP is associated with lower postoperative bleeding risk but higher long-term reoperation risk than TURP. Patients with high bleeding risk and a low likelihood of needing reoperation appear most suitable for laser vaporization.KEY MESSAGEPVP is associated with lower postoperative bleeding risk but higher long-term reoperation risk than TURP. PVP appears an attractive treatment option, especially for patients with high bleeding risk and a low likelihood of needing a reoperation.

title: Who were the people of the Fourth Cataract? Using dental non-metric traits to explore population history in the middle Nile valley from the Neolithic to Medieval period
Creators: name: Phillips, E
Publisher: name: Liverpool John Moores University
Year: 2024

description: The 4th Cataract human skeletal collection, curated at the British Museum, is unique containing remains dating from the Kerma to Medieval periods, but from within a 30km region along the Nile. The geographically focused nature of this collection provides opportunities to explore biological continuity, in situ evolution, and migration. Nubia has a long and rich history with distinct shifts in cultural practices. Situated between sub-Saharan Africa to the south and Egypt/Mediterranean to the north, Nubia is often considered a corridor through the Sahara. Many archaeological excavations have taken place there in the recent years, steadily increasing the number of skeletal collections available for study. These distinctive qualities make Nubia ideal for investigating population movement and origins of the cultures that developed there. Dental nonmetric traits, following the Arizona State University Dental Anthropology System, were used to study inter-group differences based on biodistances. Both model-free and model-bound statistical analyses were used. Data from the 4th Cataract were compared to samples from Upper and Lower Nubia to investigate both geographical and temporal patterning. Results were then contextualised further through comparisons with samples from East Africa and proximate regions in Eurasia. Results revealed biological continuity in the 4th Cataract region from the Kerma through Medieval periods (MMD range 0.001 - 0.082). Continuity was also observed in Upper and Lower Nubia from the Neolithic onwards. Evidence for the movement of people was identified in the data, but changes were not wholesale and varied depending on region/time-period. Comparisons with East African and Eurasian published data showed that both regions were important influences in Nubian populations. Similarities between Nubian and sub-Saharan groups appear to be clinal, with influence from this region diminishing temporally from the Neolithic onwards. Biological affinities with Egyptian/Eurasian groups revealed geographical patterning, but also appear to be related to the Egyptian invasion of Nubia. This study also found that the relationship between cultural change and population movement was complex. This research highlights the importance of using both archaeological and biological methods when investigating past population dynamics.

Examining implicit and explicit attitudes toward psychotherapy versus medication

Subjects: subject: Social and Behavioral Sciences

description: This project is Study 2 in a two-part study designed to investigate implicit and explicit beliefs about the effectiveness (vs. unhelpfulness) of therapy (vs. medication) in a large, diverse sample of individuals. Participants were adults who visited the Project Implicit Mental Health website (https://implicit.harvard.edu/implicit/user/pimh/index.jsp) between 7/5/16 and 5/15/19, and chose the Treatment IAT study labeled “Do you implicitly favor medication or talk therapy?” An exploratory analysis of data collected from participants between September 2011 and November 2015 (Study 1) was first conducted to evaluate the Treatment IAT, and to investigate whether therapy-as-effective implicit associations varied as a function of age, gender, race, ethnicity, education, and mental health history. Based on these results, Study 2 aims to replicate Study 1’s findings in a more recent sample of visitors to Project Implicit Mental Health. In addition, several important changes to the mental health history questionnaire have been made to allow for a more nuanced and accurate evaluation of individuals’ mental health history. Specifically, in Study 1, participants had to choose whether they struggled with mental or emotional difficulties currently or in the past, and whether they received any help for mental or emotional difficulties currently or previously, without allowing them to select both current and previous options. In Study 2, these questions were modified to allow participants to choose previous, current, or both. This would capture, for instance, someone who is currently depressed and has also had prior episodes. Additionally, the mental health history questionnaire now asks whether an individual has struggled with specific mental health diagnoses (using a checklist of common diagnoses) rather than mental health or emotional difficulties broadly, and includes additional questions on the duration of mental health difficulties, and on the helpfulness of each mental health help-seeking experience. These changes were made to allow for a more thorough investigation of how implicit and explicit attitudes toward therapy and medication vary based on one’s mental health history. Thus, in addition to replicating findings from Study 1, Study 2 will test how implicit and explicit mental health treatment attitudes vary based on these new mental health history variables.

description: We have identified a new class of Asymptotic Giant Branch (AGB) stars in the Small and Large Magellanic Clouds (SMC/LMC) using optical to infrared photometry, light curves, and optical spectroscopy. The strong dust production and long-period pulsations of these stars indicate that they are at the very end of their AGB evolution. Period-mass-radius relations for the fundamental-mode pulsators give median current stellar masses of 1.14 M_sun in the LMC and 0.94 M_sun in the SMC (with dispersions of 0.21 and 0.18 M_sun, respectively), and models suggest initial masses of <1.5 M_sun and <1.25 M_sun, respectively. This new class of stars includes both O-rich and C-rich chemistries, placing the limit where dredge-up allows carbon star production below these masses. A high fraction of the brightest among them should show S star characteristics indicative of atmospheric C/O ~ 1, and many will form O-rich dust prior to their C-rich phase. These stars can be separated from their less-evolved counterparts by their characteristically red J-[8] colors.

description: We study theoretically a possibility of creation and ultrafast control (erasing, spatial frequency multiplication) of population density gratings in a multi-level resonant medium having a resonance transition frequency in the THz range. These gratings are produced by subcycle THz pulses coherently interacting with a nonlinear medium, without any need for pulses to overlap, thereby utilizing an indirect pulse interaction via an induced coherent polarization grating. High values of dipole moments of the transitions in the THz range facilitate low field strength of the needed THz excitation. Our results clearly show this possibility in multi-level resonant media. Our theoretical approach is based on an approximate analytical solution of time-dependent Schrödinger equation (TDSE) using perturbation theory. Remarkably, as we show here, quasi-unipolar subcycle pulses allow more efficient excitation of higher quantum levels, leading to gratings with a stronger modulation depth. Numerical simulations, performed for THz resonances of the H20 molecule using Bloch equations for density matrix elements, are in agreement with analytical results in the perturbative regime. In the strong-field non-perturbative regime, the spatial shape of the gratings becomes non-harmonic. A possibility of THz radiation control using such gratings is discussed. The predicted phenomena open novel avenues in THz spectroscopy of molecules with unipolar and quasi-unipolar THz light bursts and allow for better control of ultra-short THz pulses.

Perceptions of Carbon Taxes in North Carolina
Creators: name: Buenrostro, Kathia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Carbon taxes have the potential to reduce carbon emissions to slow global warming and the impacts of climate change. The literature has focused on studying carbon taxes in left-leaning places such as British Columbia and Colorado. I conducted interviews with key stakeholders to better understand the challenges, misconceptions, and opportunities regarding carbon taxes in North Carolina, a more moderate state, to begin to fill the gap. In general, stakeholders believe that (1) revenue-neutral carbon taxes will be the most politically viable, (2) there should be a great deal of transparency about the purpose of the tax and the destination of the revenue, and (3) events such as hurricanes have potential to prompt carbon taxes. Stakeholders who would prefer to use the revenue for environmental initiatives would prefer those that have co-benefits and build resiliency at the local level. While Carbon taxes should only be implemented after more thorough stakeholder involvement, this project begins to inform this larger process, particularly for North Carolina researchers interested in carbon pricing and climate policies.

When a network evolves, there may exist subgraphs within which the internal flows generally follow a rule: the change rates of the flow intensity are either collectively high or low. Classic network measures such as degree, clustering, and betweenness can be used to quantify the process of network evolution by profiling the variation in overall properties over time and analyzing such variations at either the network or node level. However, it remains challenging to directly identify and explain how a spatial network is evolving at a mesoscopic scale. To bridge this gap, we introduce the concept of the Collective Flow Evolution Pattern (CFEP) as a mesoscopic description for spatial network evolution. Four types of patterns with distinct characteristics are defined to clarify the collective evolutionary behaviors of flows. We also provide an analytical framework that utilizes flow change rates in sequential spatial network snapshots to detect CFEPs as optimized flow groups. Simulation experiments are conducted to validate the proposed framework, and a case study of large-scale human mobility data from the Twin Cities Metropolitan Area, Minnesota, US, is presented to explore the human mobility network evolution.

description: A shape sensitive, variational approach for the matching of surfaces considered as thin elastic shells is investigated. The elasticity functional to be minimized takes into account two different types of nonlinear energies: a membrane energy measuring the rate of tangential distortion when deforming the reference shell into the template shell, and a bending energy measuring the bending under the deformation in terms of the change of the shape operators from the undeformed into the deformed configuration. The variational method applies to surfaces described as level sets. It is mathematically well-posed and an existence proof of an optimal matching deformation is given. The variational model is implemented using a finite element discretization combined with a narrow band approach on an efficient hierarchical grid structure. For the optimization a regularized nonlinear conjugate gradient scheme and a cascadic multilevel strategy are used.

description: We report on the observation of a new phenomenon occurring in a fiber ring laser. This phenomenon is about the transition from an initially bidirectional emission of a reciprocal fiber ring laser to a unidirectional emission at a certain pump power threshold. In addition, the final direction is not predefined but appears to be randomly chosen every time the threshold is exceeded. Therefore, we term this new phenomenon direction instability. Furthermore, we provide a first discussion of how the instability threshold is influenced by the length and the loss of the cavity. We show that the threshold follows a power times length scaling, indicating a nonlinear origin.
Finiteness conditions and cotorsion pairs

description: We study the interplay between the notions of $n$-coherent rings and finitely $n$-presented modules, and also study the relative homological algebra associated to them. We show that the $n$-coherency of a ring is equivalent to the thickness of the class of finitely $n$-presented modules. The relative homological algebra part comes from the study of orthogonal complements to this class of modules with respect to ${\rm Ext}^1_R(F,-)$ and ${\rm Tor}_1^R(F,-)$. We also construct cotorsion pairs from these orthogonal complements, allowing us to provide further characterizations of $n$-coherent rings.

description: Smart polymeric systems are required that are able to release a therapeutic drug with control over timing and location of delivery. Herein we have investigated the architecture-controlled and pH-triggered release of ibuprofen from a polymeric nanoparticle system prepared using ring-opening metathesis polymerisation. The co-polymerisation of norbornene-derived ibuprofen (NB-Ibu) and poly(ethylene glycol) (NB-PEG) monomers produced polymers with block and random sequence architectures. Self-assembly into nanoparticle systems and release of ibuprofen only under basic conditions was shown to be controlled by polymer sequence.

description: Let $W$ be a subset of the set of real points of a real algebraic variety $X$. We investigate which functions $f: W \to \mathbb R$ are the restrictions of rational functions on $X$. We introduce two new notions: ${\it curve-rational \, functions}$ (i.e., continuous rational on algebraic curves) and ${\it arc-rational\, functions}$ (i.e., continuous rational on arcs of algebraic curves). We prove that under mild assumptions the following classes of functions coincide: continuous hereditarily rational (introduced recently by the first named author), curve-rational and arc-rational. In particular, if $W$ is semialgebraic and $f$ is arc-rational, then $f$ is continuous and semialgebraic. We also show that an arc-rational function defined on an open set is arc-analytic (i.e., analytic on analytic arcs). Furthermore, we study rational functions on products of varieties. As an application we obtain a characterization of regular functions. Finally, we get analogous results in the framework of complex algebraic varieties.
Elliptically polarized high-harmonic radiation for production of isolated attosecond pulses

description: Circularly polarized attosecond pulses are powerful tool to study chiral light-matter interaction via chiral electron dynamics. However, access to isolated circularly polarized attosecond pulses enabling straightforward interpretation of measurements, still remains a challenge. In this work, we experimentally demonstrate the generation of highly elliptically polarized high-harmonics in a two-color, bi-circular, collinear laser field. The intensity and shape of the combined few-cycle driving radiation is optimized to produce a broadband continuum with enhanced spectral chirality in the range of 15-55 eV supporting the generation of isolated attosecond pulses with duration down to 150 as. We apply spectrally resolved polarimetry to determine the full Stokes vector of different spectral components of the continuum, yielding a homogenous helicity distribution with ellipticity in the range of 0.8-0.95 and a negligible unpolarized content.
Assessment of Centralized Kitchens for Multigenerational Populations in North Carolina: A Case Study Approach
Creators: name: Pollan, Hilary
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This masters project, driven by a proposal from community partner Food Insight Group (FIG), assesses the potential for centralized kitchens in North Carolina to meet the nutritional needs of multigenerational populations that participate in federally-subsidized meal programs, specifically among older adult and early childhood populations. Additionally, the project explores how centralized kitchens can play an integrating role in developing local food supply chains. Three case studies of existing centralized kitchens serving older adults and/or early childhood education centers - WAGES NC in Wayne County, Food Runner’s Collaborative in Raleigh, and Child Care Services Association in Durham -  were conducted. This project identified that inter-organizational collaboration on centralized kitchens offers an effective solution to serve federally-funded older adults and early childhood education meal programs within a region, as long as the organizational partners have shared missions and are committed to carefully coordinating operations within the centralized kitchen. Furthermore, centralized kitchens are best able to procure local food to support small and mid-size farmers when a local food supply chain already exists within the region. The results of this project will be used to inform FIG’s future decisions about nutritional interventions to meet the needs of multigenerational populations, and may be useful for other advocates considering inter-organizational collaborative approaches to address the nutritional needs of a community.

description: As an innovative transport alternative for short-distance trips, dock-less bike share has swept across the globe since 2016. Its great convenience, flexibility, low fare and health benefits attract urban dwellers' interests. For cities, it also created great economic value, environmental benefits and close integration with existing public transit system.

With dozens of bike-share companies quickly flooding city streets with millions of brightly colored shared bicycles, China is experiencing a bike share boom since 2016. In this study, I take Shenzhen as a research example to explore how bike sharing usage pattern is affected by different factors. The results reveal that there are five significant hot spots of bike share usage in Shenzhen, presenting a distinct  layer structure. In addition, the results also indicate population, employment, restaurants, companies, schools, urban road network, metro station and bike availability are the most significant influencing factors.

Various stakeholders can take advantage of the analysis. For bike share operation companies, they should prioritize the integration of bike share and metro system rather than bus system. In addition, it is important to deploy specialized team to work on the oversupply and under-supply of bikes during peak hours. For government, the real-time data generated by bike share usage could assist decision-makers to deploy the bike-related infrastructure, even the transport infrastructure in a more effective way.

In short, there is an interesting and complicated interaction between bike sharing activities and our urban environment. We are looking forward to seeing bike sharing to bring more amazing changes and surprises to our cities!

description: Using unique recently released nationally representative high-quality data at the plant level, this paper presents the first comprehensive evidence on the relationship between productivity and size of the export market for Germany, a leading actor on the world market for manufactured goods. It documents that firms that export to countries inside the euro-zone are more productive than firms that sell their products in Germany only, but less productive than firms that export to countries outside the euro-zone, too. This is in line with the hypothesis that export markets outside the euro-zone have higher entry costs that can only by paid by more productive firms.
