description: The purpose of this qualitative study is to understand the perceived patient barriers and facilitators of post-surgical exercise adherence in patients undergoing TKA. We used an interpretive description approach. Data was gathered using semi-structured qualitative interviews. Participants were interviewed at 8 weeks post-operatively to capture physical, psychological, social and contextual changes and information. Topics that were explored included participants’ experience with physical activity and exercise, motivation to perform physical activity, beliefs that exercise will reduce pain, factors that limit their ability to engage in exercise, and the importance of self-regulation in exercise adherence. This study identified 4 themes within the WHO adherence framework: patient-related factors, condition-related factors, health care system, and social support. In particular, self-regulation, knowledge of exercise, post-operative complications, comorbidities, social support, and lack of guidance from health care providers were identified as personal and environmental characteristics that influence exercise adherence. Exercise adherence is a multidimensional, interconnected construct and future research should focus on understanding the factors, particularly health care system, that impact adherence.IMPLICATIONS FOR REHABILITATIONRehabilitation therapists should aim to foster competence and confidence in post-operative rehabilitation by implementing strategies such as positive-reinforcement, goal setting, and increased education regarding the benefits of exercise.Clinical strategies to improve exercise adherence should be implemented both pre-and-post-operatively.Health care providers should clearly discuss post-operative outcomes and expectations (e.g., complications, etc.) with patients prior to surgery.

Planning, Social Infrastructure, and the Maker Movement in New York City

description: In recent years, the maker movement has captured the imaginations of policy makers and planners across the United States. As with any large, potentially paradigmatic idea (think “sustainability” or “resiliency”), the phenomenon has quickly become freighted with overlapping, competing, and sometimes contradictory meanings (Markusen 1999). Making is sometimes characterized as a distinct mode of production, enabled by the widespread commercial availability of design and prototyping platforms and fabrication tools (Stangler and Maxwell 2012; Milstein Symposium 2014). Other definitions place consumption center stage, highlighting people’s desire to eat, wear, and use products that have been created locally (Heying 2010; Roy 2015), or that are customized to personal specifications (Maker Media and Deloitte Center for the Edge 2013; Bryson, Clark, and Mulhall 2014). Still other definitions center on individuals’ yearning to reconnect with the material world, to “engage passionately with objects in ways that make them more than just consumers” (Dougherty 2012, 12).

description: Phylogenetic generalized least squares (PGLS) regression is widely used to detect evolutionary correlations. In contrast to the equal treatment of analyzed traits in conventional correlation methods such as Pearson and Spearman's rank tests, we must designate one trait as the independent variable and the other as the dependent variable. However, in our PGLS regression analyses (using Pagel's λ model) of both empirical and simulated datasets, switching independent and dependent variables yielded many conflicting results. A serious problem with PGLS regression that has not been noticed before is that selecting an inappropriate trait as the dependent variable will often result in an error. To assess correlations in simulated data, we established a gold standard by analyzing changes in traits along phylogenetic branches. Next, we tested seven potential criteria for dependent variable selection: log-likelihood, Akaike information criterion, R2, p-value, Pagel's λ, Blomberg et al.'s K, and the estimated λ in Pagel's λ model. We determined that the last three criteria performed equally well in selecting the dependent variable and were superior to the other four. For practicality, we suggest using the trait with a higher λ or K value as the dependent variable in future PGLS regressions. In analyzing the evolutionary relationship between two traits, we should designate the trait with a stronger phylogenetic signal as the dependent variable even if it could logically assume the cause in the relationship.

Civic Meaning: The Role of Place, Typology and Design Values in Urbanism
Creators: name: Groat, Linda N.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2000

description: What is civic meaning? How might such meaning be expressed and conveyed through urban design? Are some urban design strategics better than others in conveying civic meaning? These are the questions I was asked to address as part of the University of North Carolina's spring 1999 symposium on "Traditional Urbanism Reconsidered." I approach these questions from the perspective of an academic researcher who has been investigating the topic of 'environmental meaning' for more than two decades, through empirical studies and theoretical analyses. Environmental meaning, as I and other researchers have framed it, highlights the importance and complexity of the processes by which people apprehend and construct meaning in their physical environments, from small to large scale, including both built and natural environments. Within this larger framework, the notion of civic meaning raises the question of how the urban or town scale environment might convey a sense of citizenship, civic engagement, and community cohesion. Given the theme of the symposium, the implicit question being posed is whether traditional urbanism and/or New Urbanism are likely to be more successful than Modernist and typical suburban developments in engendering civic meaning. This of course is a complex question, one that defies a simple answer. None of the urban design strategies - traditional, Modernist, suburban, or New Urbanist - is by any means monolithic. The range of examples is endless, the quality of execution completely variable. Nevertheless, it is vitally important to address the question because the quality of our experiences in neighborhoods and cities depends on it. In this article, I begin from the premise that 'civic meaning' is a critical, but often missing, ingredient in our lives as citizens in our communities. Achieving authentic civic meaning requires that it be embedded in our social practices - especially the processes enacted for making and sustaining communities, in the actual physical form of our communities, and even in our fundamental values. As a prelude to the discussion of the extent to which various forms of urban design (e.g. typical suburban development or New Urbanist) are capable of engendering civic meaning, three underlying principles will be examined: 1) the model of place experience, 2) the notion of typology as means by which people interpret physical form, and 3) the concept of the designer-as-cultivator, based on an understanding of organizational and environmental values.

description: Urban sprawl is a hot-button issue in the U.S. Though the term is widely used to describe the distaste for contemporary American suburban and urban development, a select few group of researchers, academics and practitioners have led the response to the argument against sprawl. This paper seeks to characterize sprawl from the perspective of landscape architecture while focusing on quantitative measurements and definitions of sprawl. At its core it examines the issue of the evolution of urban form through time, and offers options for addressing the debates over the negative or positive ramifications of sprawl.

description: Layered molecular materials and especially MoS2 are already accepted as promising candidates for nanoelectronics. In contrast to the bulk material, the observed electron mobility in single-layer MoS2 is unexpectedly low. Here we reveal the occurrence of intrinsic defects in MoS2 layers, known as inversion domains, where the layer changes its direction through a line defect. The line defects are observed experimentally by atomic resolution TEM. The structures were modeled and the stability and electronic properties of the defects were calculated using quantum-mechanical calculations based on the Density-Functional Tight-Binding method. The results of these calculations indicate the occurrence of new states within the band gap of the semiconducting MoS2. The most stable non-stoichiometric defect structures are observed experimentally, one of which contains metallic Mo-Mo bonds and another one bridging S atoms.

description: Informal caregivers provide ongoing assistance to a loved one with a health condition. No studies have compared caregiving intensity and perception of burden across chronic medical conditions. Databases were searched from inception through 11 September 2020 to identify studies that included the Level of Care Index or the Zarit Burden Inventory (ZBI) among caregivers for people with chronic diseases. Pooled mean ZBI scores and 95% confidence intervals by medical condition were calculated using a random effects model and heterogeneity with I2. Ninety-seven included articles reported on 98 unique samples across 21 chronic diseases. No study used the Level of Care Index. Among 12 disease groups with more than one study, heterogeneity was too high (I2 range: 0–99.6%, ≥76.5% in 11 groups) to confidently estimate burden. The percent of studies rated high risk of bias ranged from 0% to 98%, but all external validity items were rated as high-risk in >50% of studies. Findings highlight the need for studies on caregiver burden to improve sampling techniques; better report sampling procedures and caregiver and care recipient characteristics; and develop a standard set of outcomes, including a measure of caregiving intensity. Systematic Review Registration: CRD42017080962IMPLICATIONS FOR REHABILITATIONThe amount of burden reported by caregivers to loved ones is associated with reduced physical and mental health.We found considerable heterogeneity in perceived burden reported by informal caregivers across different studies within disease groups, which is likely related to methodological issues, including sampling techniques.Health care providers who use research on caregiver burden should assess how representative study samples may be and exercise caution in drawing conclusions.

The role of the Legendre transform in the study of the Floer complex of cotangent bundles

description: Consider a classical Hamiltonian H on the cotangent bundle T*M of a closed orientable manifold M, and let L:TM -> R be its Legendre-dual Lagrangian. In a previous paper we constructed an isomorphism Phi from the Morse complex of the Lagrangian action functional which is associated to L to the Floer complex which is determined by H. In this paper we give an explicit construction of a homotopy inverse Psi of Phi. Contrary to other previously defined maps going in the same direction, Psi is an isomorphism at the chain level and preserves the action filtration. Its definition is based on counting Floer trajectories on the negative half-cylinder which on the boundary satisfy "half" of the Hamilton equations. Albeit not of Lagrangian type, such a boundary condition defines Fredholm operators with good compactness properties. We also present a heuristic argument which, independently on any Fredholm and compactness analysis, explains why the spaces of maps which are used in the definition of Phi and Psi are the natural ones. The Legendre transform plays a crucial role both in our rigorous and in our heuristic arguments. We treat with some detail the delicate issue of orientations and show that the homology of the Floer complex is isomorphic to the singular homology of the loop space of M with a system of local coefficients, which is defined by the pull-back of the second Stiefel-Whitney class of TM on 2-tori in M.

Year: 1990

description: The latter part of the 1980s saw a revival of concern about environmental issues. These issues began to occupy more of policy makers' time and attention at both the national and local levels. Little has been done to evaluate public opinion about the difficult choices between the environment and growth and development, however. In October 1989, MarketSearch Corporation of Columbia, S.C., conducted a telephone survey of 1500 residents of North and South Carolina, 750 from each state, on economic development and the environment. The purpose of the study was to evaluate public opinions and attitudes about these two important areas and how people in the two Carolinas feel about them. This report focuses on the viewpoints of North Carolinians by highlighting some of the study's key findings.

Changing Institutional Structures to Improve the Coordination of Land Use and Transportation in the Research Triangle

Year: 2001

description: When Sandy Ogburn, Assistant to the General Manager at Triangle Transit Authority (TTA), first arrived in the North Carolina Research Triangle region from Philadelphia, she planned to stay only two years. However, because of "the slower pace of life, all the amenities in the region, and the beautiful blue color of the sky," she and her family have made the Triangle home for over 25 years. During that time, Ms. Ogburn has been an active member of the Triangle community, serving as a member of the Durham City Council, as chair of the Durham-Chapel Hill-Carrboro Metropolitan Planning Organization (DCHC MPO) Transportation Advisory Committee, and as chair of the TTA Board of Directors. Unfortunately, recent trends may threaten the high quality of life that has attracted people, like Ogburn. and businesses to the Triangle in the past. Traffic congestion and air pollution problems that have plagued other fast-growing metropolitan areas have come to the Triangle. According to the North Carolina Department of Environment and Natural Resources (NC DENR), the Research Triangle region experienced eight Code Red ("unhealthy") and twenty-three Code Orange ("unhealthy for sensitive groups") ozone days in 1999 (NC DENR 2000). Automobile emissions are a major source of this pollution, and an inefficient regional transportation system contributes to the emissions problem by exacerbating traffic congestion. Traffic volumes on Interstate 40 at the Wake-Durham county line increased from about 71,000 vehicles per day in 1990 to over 11,000 vehicles per day by 1995 (Eisenstadt and Hoar 1995). Commuters often spend an hour traversing the 10-mile stretch of Interstate 40 between Research Triangle Park and Raleigh. The region's congestion problem has increasingly drawn press coverage, with helicopter traffic reports and live views from traffic cameras broadcast each night on the local news.

description: We measure surface recombination velocities (SRVs) below 10 cm/s on low-resistivity (1.4 Ωcm) p-type crystalline silicon wafers passivated with plasma-assisted and thermal atomic layer deposited (ALD) aluminium oxide (Al2O3) films. Ultrathin Al2O3 films (< 5 nm) are particularly relevant for the implementation into solar cells, as the deposition rate of the ALD process is very low compared to e.g. plasma-enhanced chemical vapor deposition (PECVD). Hence, we examine the passivation quality of a stack consisting of an ultrathin Al2O 3 passivation layer deposited by ALD and a SiNx capping layer deposited by PECVD. Our experiments show a substantial improvement of the thermal stability during firing at 810°C for the Al2O 3/SiNx stacks compared to a single Al2O 3 layer. We report on a 'regeneration effect' observed for Al 2O3 single layers after firing, where the degraded passivation is significantly improved after annealing at 400°C and also by illumination at room temperature using a halogen lamp. Nevertheless, for Al 2O3/SiNx stacks we measure SRVs < 15 cm/s after firing, whereas for Al2O3 single layers the regenerated SRVs are in the range of 10-30 cm/s. Al2O 3/SiNx stacks are hence ideally suited for the implementation into industrial-type silicon solar cells, although 'regenerated' Al2O3 single layers should result in a comparable cell performance.

description: In diesem Open-Access-Buch geht Steve Kenner der Frage nach, inwiefern sich politische Bildungsprozesse aus den Partizipationserfahrungen junger Menschen rekonstruieren lassen. Er begleitete politische Jugendinitiativen und führte Interviews mit politisch aktiven Jugendlichen (u.a. Fridays for Future und Antirassismus-Arbeitsgemeinschaften). Die Ergebnisse der Untersuchung offenbaren, dass die selbstbestimmte politische Aktion zu vielfältigen Bildungsgelegenheiten führt. Quellenkritik, Recherche, Auseinandersetzung mit vielfältigen Perspektiven sowie das sachliche und wertgebundene Beurteilen zeichnen die Erfahrungen der Jugendlichen aus. Sie erleben Selbstwirksamkeit, lernen mit Misserfolgen umzugehen, Konflikte zivil zu lösen, sich im Kollektiv politisch zu organisieren und damit verbundene Herausforderungen zu bewältigen. Die begleiteten Gruppen erweisen sich nicht als homogene politische Gemeinschaft. Und dennoch besteht die Gefahr der Verinselung in ihrem Protest. Hier kann und sollte die formale politische Bildung und die demokratische Schulentwicklung ansetzen und die Partizipationserfahrungen in der politischen Aktion als Bildungsgelegenheit verstehen.

description: We present a new fabrication method for epitaxial graphene on SiC which enables the growth of ultra-smooth defect- and bilayer-free graphene sheets with an unprecedented reproducibility, a necessary prerequisite for wafer-scale fabrication of high quality graphene-based electronic devices. The inherent but unfavorable formation of high SiC surface terrace steps during high temperature sublimation growth is suppressed by rapid formation of the graphene buffer layer which stabilizes the SiC surface. The enhanced nucleation is enforced by decomposition of deposited polymer adsorbate which acts as a carbon source. Unique to this method are the conservation of mainly 0.25 and 0.5 nm high surface steps and the formation of bilayer-free graphene on an area only limited by the size of the sample. This makes the polymer-assisted sublimation growth technique a promising method for commercial wafer scale epitaxial graphene fabrication. The extraordinary electronic quality is evidenced by quantum resistance metrology at 4.2 K showing ultra-high precision and high electron mobility on mm scale devices comparable to state-of-the-art graphene.
Optimal enumeration of state space of finitely buffered stochastic molecular networks and exact computation of steady state landscape probability

description: Stochasticity plays important roles in molecular networks when molecular concentrations are in the range of $0.1 μ$M to $10 n$M (about 100 to 10 copies in a cell). The chemical master equation provides a fundamental framework for studying these networks, and the time-varying landscape probability distribution over the full microstates provide a full characterization of the network dynamics. A complete characterization of the space of the microstates is a prerequisite for obtaining the full landscape probability distribution of a network. However, there are neither closed-form solutions nor algorithms fully describing all microstates for a given molecular network. We have developed an algorithm that can exhaustively enumerate the microstates of a molecular network of small copy numbers under the finite buffer condition that the net gain in newly synthesized molecules is smaller than a predefined limit. We also describe a simple method for computing the exact mean or steady state landscape probability distribution over microstates. We show how the full landscape probability for the gene networks of the self-regulating gene and the toggle-switch in the steady state can be fully characterized. We also give an example using the MAPK cascade network. Our algorithm works for networks of small copy numbers buffered with a finite copy number of net molecules that can be synthesized, regardless of the reaction stoichiometry, and is optimal in both storage and time complexity. The buffer size is limited by the available memory or disk storage. Our algorithm is applicable to a class of biological networks when the copy numbers of molecules are small and the network is closed, or the network is open but the net gain in newly synthesized molecules does not exceed a predefined buffer capacity.

description: In this paper a DWT based steganography in frequency domain, termed as ATFDWT has been proposed. Here, the cover image is transformed into the time domain signal through DWT, resulting four sub-image components as 'Low resolution', 'Horizontal orientation', 'Vertical orientation' and 'Diagonal orientation'. The secret message/image bits stream in varying positions are embedded in 'Vertical orientation sub-image' followed by reverse transformation to generate embedded/encrypted image. The decoding is done through the reverse procedure. The experimental results against statistical and visual attack has been computed and compared with the existing technique like IAFDDFTT[1], in terms of Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR), Standard Deviation(SD) and Image Fidelity(IF) analysis, which shows better performances in ATFDWT.

description: We construct in the K matrix formalism concrete examples of symmetry enriched topological phases, namely intrinsically topological phases with global symmetries. We focus on the Abelian and non-chiral topological phases and demonstrate by our examples how the interplay between the global symmetry and the fusion algebra of the anyons of a topologically ordered system determines the existence of gapless edge modes protected by the symmetry and that a (quasi)-group structure can be defined among these phases. Our examples include phases that display charge fractionalization and more exotic non-local anyon exchange under global symmetry that correspond to general group extensions of the global symmetry group.

description: We propose a simple theoretical model which explains a formation of dipolar 2D and 3D colloidal structures in nematic liquid crystal. Colloidal particles are treated as effective hard spheres interacting via their elastic dipole, quadrupole and octopole moments. It is shown that octopole moment plays an important role in the formation of 2D and 3D nematic colloidal crystals. We generalize this assumption on the case of the external electric field and theoretically explain a giant electrostriction effect in 3D crystals observed recently [A. Nych et al., Nature Communications \textbf{4}, 1489 (2013)].

Robust Auxiliary Vector Filtering with Constrained Constant Modulus Design for Beamforming
Creators: name: Wang, Lei

Subjects: subject: Information Theory (cs.IT)

description: This paper proposes an auxiliary vector filtering (AVF) algorithm based on a constrained constant modulus (CCM) design for robust adaptive beamforming. This scheme provides an efficient way to deal with filters with a large number of elements. The proposed beamformer decomposes the adaptive filter into a constrained (reference vector filters) and an unconstrained (auxiliary vector filters) components. The weight vector is iterated by subtracting the scaling auxiliary vector from the reference vector. The scalar factor and the auxiliary vector depend on each other and are jointly calculated according to the CCM criterion. The proposed robust AVF algorithm provides an iterative exchange of information between the scalar factor and the auxiliary vector and thus leads to a fast convergence and an improved steady-state performance over the existing techniques. Simulations are performed to show the performance and the robustness of the proposed scheme and algorithm in several scenarios.

description: We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measurement of the sensitivity. Our method determines the usefulness of the state for the usual protocol for estimating the angle of rotation with Dicke states, which is based on the measurement of the second moment of a total spin component. It can also be used to detect entangled states that are useful for quantum metrology. We apply our method to recent experimental results.
Carrier envelope phase effects in ultrafast, strong-field ionization dynamics of multielectron systems: Xe and CS$_2$

description: Carrier envelope phase (CEP) stabilized 5 fs and 22 fs pulses of intense 800 nm light are used to probe the strong-field ionization dynamics of multielectron entities, xenon and carbon disulfide. We compare ion yields obtained with and without CEP-stabilization: with 8-cycle (22 fs) pulses, Xe$^{6+}$ yields are suppressed (relative to Xe$^+$ yields) by between 30% and 50%, depending on phase, reflecting the phase dependence of non-sequential ionization and its contribution to the formation of higher charge states. On the other hand, ion yields for Xe$^{q+}$ ($q$=2-4) with CEP-stablized pulses are enhanced (by up to 50%) compared to those with CEP-unstabilized pulses. Such enhancment is particulary pronounced with 2-cycle (5 fs) pulses and is distinctly phase-dependent. Orbital shape and symmetry are found to have a bearing on the response of CS$_2$ to variations in optical field that are effected as CE phase is controllably altered, keeping the overall intensity constant. Molecular fragmentation is found to depend on field strength (not intensity); the observed relative enhancement of fragmentation when CEP-stabilized 2-cycle pulses are used is found to be at the expense of molecular ionization.

The Disconnect Between CAMA, CRC, Local Governments, and the Protection of North Carolina's Coastal Waters
Creators: name: Bierly, Richard H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2000

description: The North Carolina Coastal Area Management Act (CAMA) requires coastal counties to prepare land use plans every five years as a means of protecting the health of our coastal environment while guiding economic development. A primary role of the Coastal Resources Commission (CRC) is to assist local governments in understanding the requirements for these plans and to approve them when submitted. Some members of the Coastal Resources Advisory Council (CRAC) also participate in this review process. To offset the expense of this planning effort, the Division of Coastal Management (DCM) awards grants of up to $500,000 annually. The beauty of the concept is that it allows local governments to set their own priorities, identify local problems and challenges and to take steps to cope with them as they guide economic growth in their jurisdictions.
Multiple Isotope Magneto Optical Trap from a single diode laser

description: We present a Dual Isotope Magneto Optical Trap produced using a single diode laser. We generate all the optical frequencies needed for trapping both species using a fiber intensity modulator. All the optical frequencies are amplified simultaneously using a tapered amplifier. The independent control of each frequency is on the RF side rather than on the optical side. This introduces an enormous simplification for laser cooling applications that often require an acousto-optic modulator for each laser beam. Frequency changing capabilities are limited by the modulator bandwidth (10 GHz). Traps for more isotopes can be simply added by including additional RF frequencies to the modulator.

description: We present a new model for the calculation of the diffuse fraction of the global solar irradiance for solar system simulations. The importance of an accurate estimation of the horizontal diffuse irradiance is highlighted by findings that an inaccurately calculated diffuse irradiance can lead to significant over- or underestimations in the annual energy yield of a photovoltaic (PV) system by as much as 8%. Our model utilizes a time series of global irradiance in one-minute resolution and geographical information as input. The model is validated by measurement data of 28 geographically and climatologically diverse locations worldwide with one year of one-minute data each, taken from the Baseline Surface Radiation Network (BSRN). We show that on average the mean absolute deviation of the modelled and the measured diffuse irradiance is reduced from about 12% to about 6% compared to three reference models. The maximum deviation is less than 20%. In more than 80% of the test cases, the deviation is smaller 10%. The root mean squared error (RMSE) of the calculated diffuse fractions is reduced by about 18%.
