description: One-dimensional electronic fluids are peculiar conducting systems, where the fundamental role of interactions leads to exotic, emergent phenomena, such as spin-charge (spinon-holon) separation. The distinct low-energy properties of these 1D metals are successfully described within the theory of linear Luttinger liquids, but the challenging task of describing their high-energy nonlinear properties has long remained elusive. Recently, novel theoretical approaches accounting for nonlinearity have been developed, yet the rich phenomenology that they predict remains barely explored experimentally. Here, we probe the nonlinear spectral characteristics of short GaAs quantum wires by tunnelling spectroscopy, using an advanced device consisting of 6000 wires. We find evidence for the existence of an inverted (spinon) shadow band in the main region of the particle sector, one of the central predictions of the new nonlinear theories. A (holon) band with reduced effective mass is clearly visible in the particle sector at high energies.

Preliminary Study of The Growth of Metallic Aerosols Under Reduced Pressure Environment
Creators: name: Hsieh, Ming-Ta
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: The growth behavior of metallic aerosols under normal and reduced pressure environments was investigated. Particles grown at both environments exhibit very irregular profiles. Particles' growth, in general, can be categorized into three types in this study, they are: cluster-cluster aggregation, particle-cluster aggregation, and ballistic aggregation. A descriptor, called fractal dimension, is applied to quantifying the effect of reducing the pressure on the growth of particles. According to the measurements of fractal dimension, at higher pressure, 0.1 and 1.0 atm., cluster-cluster aggregation occurred at the early stage of growth; while particle-cluster aggregation occurred at the later stage of growth. Opposite phenomenon was found when pressure decreased to 0.01 atm.
title: Hydrolysis products generated by lipoprotein lipase and their association with oxidative stress in THP-1 macrophages
Creators: name: Monefa, Marzana
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Lipoprotein lipase (LPL) is an extracellular lipase that hydrolyzes triglycerides (TG) from TG-rich lipoproteins (Lp) within the bloodstream. In the arteries, macrophage LPL expression has been observed to negatively influence atherosclerosis and promote cardiovascular disease. Previously, our laboratory reported that Lp hydrolysis products (HPs) generated by LPL resulted in the upregulated expression of 63 small nucleolar RNAs (snoRNA) within the human macrophage cell. Interestingly, the very low-density lipoprotein (VLDL) HPs by LPL induced the production of reactive oxygen species (ROS), and the cell stress further induced the snoRNA expression in various cell models. The inhibition of NADPH oxidase (NOX) in the cell models diminished snoRNA expression. This project aimed to assess the role of Lp HPs by LPL in oxidative stress using in vitro and in silico approaches. For in vitro studies, human VLDL and chylomicron (CM) HPs generated by LPL were incubated with THP-1 macrophages, with or without a NOX inhibitor (NOXi). The ROS production and lipid peroxidation in the media and cells were analyzed. With an increase in free fatty acid (FFA) concentration from both Lp HPs by LPL, relative to control, there was a decreasing trend in ROS generation for the lowest FFA concentration followed by increasing trend for other FFA concentrations. However, when THP-1 cells were incubated with 0.5 nmol/μL FFA of both Lps HPs by LPL, there was a reduction in ROS with NOXi treatment relative to control. Extracellular ROS was higher with NOXi with 0.5 nmol/μL FFA from VLDL. On the other hand, no change in media malondialdehyde (MDA) with both Lps HPs by LPL was decreased with the addition of NOXi, while the cellular MDA was decreased with or without NOXi. For in silico analyses, available transcriptomic datasets for Lp lipolysis by LPL in two cell lines showed an upregulation of stress-inducing genes and a downregulation of genes associated with cell cycle arrest. Henceforth, my study indicated that Lp HPs by LPL may stimulate foam cell conversion through enhanced NOX-mediated ROS and extracellular MDA levels, which may lead to cellular stress and cell death.

description: We present variants of the Conjugate Gradient (CG), Conjugate Residual (CR), and Generalized Minimal Residual (GMRES) methods which are both pipelined and flexible. These allow computation of inner products and norms to be overlapped with operator and nonlinear or nondeterministic preconditioner application.The methods are hence aimed at hiding network latencies and synchronizations which can become computational bottlenecks in Krylov methods on extreme-scale systems or in the strong-scaling limit. The new variants are not arithmetically equivalent to their base flexible Krylov methods, but are chosen to be similarly performant in a realistic use case, the application of strong nonlinear preconditioners to large problems which require many Krylov iterations. We provide scalable implementations of our methods as contributions to the PETSc package and demonstrate their effectiveness with practical examples derived from models of mantle convection and lithospheric dynamics with heterogeneous viscosity structure. These represent challenging problems where multiscale nonlinear preconditioners are required for the current state-of-the-art algorithms, and are hence amenable to acceleration with our new techniques. Large-scale tests are performed in the strong-scaling regime on a contemporary leadership supercomputer, where speedups approaching, and even exceeding $2\times$ can be observed. We conclude by analyzing our new methods with a performance model targeted at future exascale machines.

Positive Behaviour Support: Development and evaluation of an online staff training protocol
Creators: name: Conlon, Niall
Publisher: name: London South Bank University
Year: 2021

description: Positive behaviour support (PBS) is recognised as an evidenced based approach to addressing challenging behaviours exhibited by people with intellectual disabilities (IDD). The quality of staff performance is a crucial determinants of client outcomes but the comparative effectiveness of PBS training methods with regard to staff behaviour is rarely studied. The purpose of the current programme of research was to examine the effectiveness of behavioural training protocols in providing frontline care staff with the knowledge and skills required to deliver PBS. Firstly, a systematic review was conducted to expand on previous reviews of PBS training by including recent studies of PBS training and refining inclusion criteria to be more relevant to social care settings. Results indicated that training duration, skills practice and supervision were important determinants of positive training outcomes. The need for more comparision and control trials was also identified. Study 1 investigated the comparative effectiveness of behavioural skills training (BST) and workshop training on staff knowledge and competence, finding that there were no differences between groups in knowledge or competence at post-test. An analysis of interview data indicated that participants preferred BST and had a positive view of PBS. Participants believed that organisational factors, training individualisation and skills practice were important determinants of training success. In Study 2, a three-arm randomised controlled trial evaluated the comparative effectiveness of programmed instruction (PI), standard online instruction (SOI) and workshop training on participants attitudes, knowledge and application of knowledge related to PBS. It found that knowledge and application score increases were highest for those in the PI condition and lowest within the workshop condition. No changes to attitudes to challenging behaviour were observed following training. Study 3 utilised a within-subjects, pre-post-test design to evaluate the impact of PI training on the participants’ attitudes to challenging behaviour, knowledge of PBS, burnout and intervention design abilities. Results indicated that PI based PBS training was effective in increasing staff knowledge. While burnout was observed to have decreased following training, no changes in attitudes to challenging behaviour or intervention design ability were observed. The findings of the thesis indicate that in addition to previously identified features of PBS training, training methodology impacts significantly on training outcomes. They also suggest that online PI-based PBS training is an effective training methodology. Evidence from the thesis’ studies isuggest that PBS training can have positive impacts on outcomes with regard to PBS knowledge, performing behaviour analytic procedures, applying knowledge and staff burnout. Implications for future PBS training research and practice are discussed.

description: Same-sex sexual behavior is ubiquitous in the animal kingdom, but its adaptive origins remain a prominent puzzle. Here I suggest the possibility that same-sex sexual behavior arises as a consequence of the competition between an evolutionary drive for a wide diversity in traits, which improves the adaptability of a species, and a drive for sexual dichotomization of traits, which promotes opposite-sex attraction and increases the rate of reproduction. A simple analytical "toy model" is proposed for describing this tradeoff. The model exhibits a number of interesting features, and suggests a simple mathematical form for describing the sexual orientation continuum.

Factors Influencing the Effectiveness of In-Room Filtration Units (Portable Air Cleaning Devices) for Controlling Certain Viable Aerosols
Creators: name: Hsu, Chang-Fu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: With the recent increase in the number of tuberculosis cases in the United States, the potential presence in hospital air of viable aerosols such as the bacteria causing Tuberculosis (Tb), Mycobacterium tuberculosis (Mtb), has started a search for a solution to the problem of providing and maintaining organism-free hospital air. In many instances it is difficult, if not impossible, to modify or upgrade hospital HVAC systems to provide adequate air cleaning, so the use of in-room air cleaning devices offers the most promising way of controlling the spread of these bacteria. It was the objective of this study to develop design criteria and specifications for the use of in-room air cleaning devices in hospital rooms, with the specific intent of controlling the spread of the bacteria causing tuberculosis. Evaluation was carried out through use of a mixing factor, K, which was the dependent variable used to determine the influence of various factors on the efficacy of a filtration unit. Design factors such as air flow rate and the configuration of the air inlet and outlet on air cleaner performance were evaluated. In addition, data on the effect of air cleaner location within a room and the consequence of furniture within a room on altering the overall room aerosol concentration was investigated. Furthermore, the results indicate that it is difficult, if not impossible, to define standard design specifications due to hospital room variation such as room volume and furniture arrangement, presence or lack of windows, etc. However, the method of evaluation is such that it can be used as the theoretical basis to design the in-room filtration unit and develop the specifications of the in-room filtration unit by utilizing the concept of air mixing and particle concentration decay rates.

An Investigation of Variance Associated with Carolina Power & Light's Emergency Air Samplers at the Shearon Harris Energy& Environmental Center
Creators: name: Rushing, David Albert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Carolina Power & Light Company has two nuclear power plants in operation, with a third soon to go into operation. Their nuclear power program is supported by a central health physics group that has as one of its responsibilities the upkeep of emergency air samplers for use at the plants when needed. A potential problem was identified in that the plants did not all use the same air sampling components such as particulate filters and radioiodine collection cartridges. The concern was that the substitution of components could change the air flow rates from the calibrated flow rates. This study was to investigate the calibration errors in the emergency air sampling program at CP&L's central health physics facility. Both high volume and low volume air samplers are maintained in operational status. The high volume samplers are used to sample airborne particulates and the low volume samplers are used for sampling radioiodine and particulates. The high volume samplers required little testing to determine that the total error in their flow rates was well within the recommended limit of +/- 20% specified in the REGULATORY GUIDE 8.25.(1) for sampled air volumes. In a worst case scenario the high volume samplers had a 10.5% total error. The low volume samplers required more testing than did the high volume samplers because of problems discovered during the initial testing. The major problem was air leakage in the sampling head on the sampler. It was found that this air leakage would be the worst during plant use of the sampler. Because of the leakage the calibrated air flow would not be the correct value. However by using the calibrated flow rate, the calculated concentration of airborne radionuclides would be higher than the actual concentration present. Recommendations were to use the high volume samplers with no changes. There were three possible choices given in the recommendations for the low volume samplers. The first is to replace the low volume samplers with new units that have desirable features that the present samplers do not have. The second choice is to replace only the sampling heads. The third choice is to suspend any further particulate sampling with the low volume samplers in their present condition if neither of the first two recommendations were implemented.

Holographic model for heavy vector meson masses

description: The experimentally observed spectra of heavy vector meson radial excitations show a dependence on two different energy parameters. One is associated with the quark mass and the other with the binding energy levels of the quark anti-quark pair. The first is present in the large mass of the first state while the other corresponds to the small mass splittings between radial excitations. In this article we show how to reproduce such a behavior with reasonable precision using a holographic model. In the dual picture, the large energy scale shows up from a bulk mass and the small scale comes from the position of anti-de Sitter (AdS) space where field correlators are calculated. The model determines the masses of four observed S-wave states of charmonium and six S-wave states of bottomonium with , 6.1 % rms error. In consistency with the physical picture, the large energy parameter is flavor dependent, while the small parameter, associated with quark anti-quark interaction is the same for charmonium and bottomonium states.

Dosimetry of Custom Inserts for Electron Beams Produced by a Varian Clinac 1800: Effect on Dose Output and Mean Incident Energy
Creators: name: Kinsey, Charles W.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: Customizing of electron beam treatment dimensions is a common clinical technique. The degree in which the measured energy and dose output for a particular beam varies depends on the degree of blocking and the nominal energy of that beam. Published measurements for the Varian Clinac 1800 are sparse and measurements for each custom insert manufactured are time consuming. Relative output and mean incident energy measurements were performed for 160 nominal beam energy / cone / insert combinations on a Varian 1800 at the Rock Hill Radiation Therapy Center in Rock Hill, South Carolina. Relative output measurements of the manufacturer supplied cones indicated no consistency in the data for all nominal beam energies. For example, the variation in relative output for increasing treatment field dimensions for the 6 MeV beam is different than for the 20 MeV beam. For custom square inserts within each cone, however, the data presented consistent behavior for all beams. The "square root" model for approximating relative output worked well with the custom square inserts and rectangular inserts with a relatively low length to width ratio. For rectangular inserts with a high length to width ratio, the model exhibited a positive bias for all nominal beam energies and cones. It is theorized this bias may be due to the need to extrapolate the measured data for very small dimensions. By using some alternative measurement technique for these smaller dimensions, the bias may be reduced to an acceptable level. The resulting energy measurements using the manufacturer supplied cones and inserts were mimicked by the use of custom inserts defining the same square dimensions for each cone. These data showed no effect of the inserts / cones on mean incident energy for the 6 MeV, 9 MeV, and 12 MeV nominal beam energies. An effect on mean incident energy for the 16 MeV and 20 MeV beams was noted only for the cases of the 4x4 and 6x6 inserts and for cases of rectangular inserts with a high length to width ratio. The "square root" model for approximating mean incident energy appeared to be a valid predictive tool for these measurements.

The Use of Compensation in Siting Hazardous Waste Facilities: Analysis of Current Practices and Recommendations for the Future
Creators: name: Hawthorne, Marsha Kay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1988

description: Siting hazardous waste facilities has become more and more difficult because of the legacy of pollution from old sites and the public's perception of inequitable costs imposed by new ones. Since new facilities may be needed soon, the use of compensation to offset residual costs along with expanded public participation can facilitate siting and help overcome local opposition. A survey of all 50 states determined the types of compensation and expanded public participation currently used by each state. These types are divided into required versus endorsed measures, and compensation is further categorized into preventive, mitigative, and compensatory measures. States use a combination of negotiation, legislation, and administration to implement these measures. Specific types and categories of compensation as well as their primary method of implementation are tabulated by state and summarized, and these results are illustrated geographically. According to this survey, some form of compensation or expanded public participation is either required or endorsed by 35 states. Case studies demonstrating the use of these measures are compiled, and recommendations for effective types of compensation and public participation are proposed.

Examination of the Hepatic and Renal Toxicity from Concurrent Oral Exposure to Chloroform and Trichloroethylene
Creators: name: Lilly, Michelle Ziegler
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: Increased hepatic and renal toxicity occurs following concurrent exposure to carbon tetrachloride (CCl4) and trichloroethylene (TCE) relative to that seen from each chemical alone. Consequently, the interaction of TCE and chloroform (CHCl3), a close structural analogue of CCl4, was examined. Adult male F-344 rats were gavaged with 0, 0.5 or 1.0 ml CHCl3/kg, 0 or 1.0 ml TCE/kg or their factorial combinations in corn oil. Urine was collected at 0, 6, 12, 24, 36 and 48 hrs, and hepatotoxicity was assessed at 24 and 48 hrs. To examine the influence of gavage vehicle, additional rats were gavaged with 0, 0.5 or 1.0 ml CHCl3/kg, 0 or 1.0 ml TCE/kg or their factorial combinations in an aqueous vehicle (10% Emulphor 620). Urine was collected at 0, 6, 12, 24, 36 and 48 hrs, and hepatotoxicity was assessed at 24 and 48 hrs. CHCl3 alone caused hepatic and renal toxicity. At 48 hours post dosing, serum AST and LDH were observed to increase 88-146 fold and 45-48 fold, respectively, when CHCl3 was administered in corn oil. Increases in AST and LDH were significant when CHCl3 was administered in the aqueous solution; however, elevations were no more than 3-fold for either enzyme. Vehicle differences were also observed in increases of ALT and bile acids. Both were significantly elevated when administered in oil compared to the aqueous vehicle. Peak hepatotoxicity was observed to be 48 hours when CHCl3 was administered in oil whereas in the aqueous vehicle, 24 is greater or equal to 48 hours, based on elevations in ALT and bile acids. CHCl3 appeared to be more nephrotoxic when administered in the oil vehicle compared to the aqueous. Histopathological lesions (both renal tubule degeneration and renal tubule necrosis) were more severe in the groups receiving CHCl3 in oil compared to the aqueous vehicle. In contrast to CHCl3, TCE alone was not overtly toxic to either organ. Concurrent exposure to both CHCl3 and TCE produced significantly less toxicity relative to CHCl3 alone. This was observed in serum enzymes at 24 and 48 hours and in urinary enzymes at 36 and 48 hours. Additionally, histological lesions were consistently less severe when CHCl3 was administered in the presence of TCE compared to CHCl3 alone. In conclusion, hepatic and renal toxicity were observed following CHCl3 exposure and no effects were observed from TCE alone. CHCl3 was significantly more acutely hepatotoxic when administered in an oil than in an aqueous vehicle. Relative to CHCl3 alone, serum and urinary indicators were significantly decreased following concurrent administration of CHCl3 and TCE which appeared to be independent of the dosing vehicle.

description: For X a finite subset of the circle and for 0 < r <= 1 fixed, consider the function f_r : X -> X which maps each point to the clockwise furthest element of X within angular distance less than 2 pi r. We study the discrete dynamical system on X generated by f_r, and especially its expected behavior when X is a large random set. We show that, as |X| -> infinity, the expected fraction of periodic points of f_r tends to 0 if r is irrational and to 1/q if r = p/q is rational with p and q coprime. These results are obtained via more refined statistics of f_r which we compute explicitly in terms of (generalized) Catalan numbers. The motivation for studying f_r comes from Vietoris-Rips complexes, a geometric construction used in computational topology. Our results determine how much one can expect to simplify the Vietoris-Rips complex of a random sample of the circle by removing dominated vertices.

Channel Redesign: Flood Mitigation for the University of North Carolina at Chapel Hill Coker Arboretum Drainage Channel
Creators: name: Phillips, Jesse
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The Coker Arboretum drainage channel is prone to flooding during heavy storm events, such as the storm event that occurred on June 30th, 2013. The flooding on June 30th, 2013 caused about $4,200 in damages to the arboretum walking paths and sent large amounts of sediment-laden stormwater into Raleigh Street to the East. This report focuses on channel redesign as a means for flood mitigation in the Coker Arboretum. Hydraulic and hydrologic modeling, technical consultations, and field investigations were used to explore five channel redesign options under two main approaches, peak flow attenuation and an increase in channel discharge capacity. Dry detention basin performance was analyzed in an attempt to achieve peak flow attenuation. For an increase in discharge capacity, the channel was redesigned such that water levels did not surpass a critical depth, including freeboard, during a 10 year SCS - Type II design storm. The most functional and cost effective solution was determined to be an increase in discharge capacity. An implementation plan was developed and project costs were compared to the present value of future benefits.

description: We study the zero-temperature phase diagram of a spin-orbit-coupled Bose-Einstein condensate of spin $1$, with equally weighted Rashba and Dresselhaus couplings. Depending on the antiferromagnetic or ferromagnetic nature of the interactions, we find three kinds of striped phases with qualitatively different behaviors in the modulations of the density profiles. Phase transitions to the zero-momentum and the plane-wave phases can be induced in experiments by independently varying the Raman coupling strength and the quadratic Zeeman field. The properties of these transitions are investigated in detail, and the emergence of tricritical points, which are the direct consequence of the spin-dependent interactions, is explicitly discussed.

DBP Formation in North Carolina Drinking Waters: A Comparison Between Predicted and Observed Concentrations
Creators: name: Greiner, Tony
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: In this study, DBP concentrations in the water treatment plant and the distribution system were measured for six utilities in North Carolina over the period of one year. All six utilities treated their water in a conventional fashion consisting of flocculation, sedimentation, and filtration, and all disinfected using only free chlorine. The objectives of this project were: • to evaluate the levels of DBPs (THMs, HAAs) throughout the treatment plant and distribution system during three seasons for six utilities; • to model the formation of these DBPs by three different methods using the predictive equations. One of the three methods is the procedure developed and used in Malcolm Pimie's WTP Model (1992); and • to determine the ability of the model to accurately predict DBP formation by comparing the model predictions to the concentrations measured. It should be mentioned that analysis was also performed on the same North Carolina database and investigated the trends and correlations between DBP formation and water quality characteristics. The results of this study can be found in the Master's Thesis by Alexa Obolensky titled DBP Formation in North Carolina Drinking Waters: Observations and Correlations (1992).

description: Let $G$ be a graph and $p \in [1, \infty]$. The parameter $f_p(G)$ is the least integer $k$ such that for all $m$ and all vectors $(r_v)_{v \in V(G)} \subseteq \mathbb{R}^m$, there exist vectors $(q_v)_{v \in V(G)} \subseteq \mathbb{R}^k$ satisfying $$\|r_v-r_w\|_p=\|q_v-q_w\|_p, \ \text{ for all }\ vw\in E(G).$$ It is easy to check that $f_p(G)$ is always finite and that it is minor monotone. By the graph minor theorem of Robertson and Seymour, there are a finite number of excluded minors for the property $f_p(G) \leq k$. In this paper, we determine the complete set of excluded minors for $f_\infty(G) \leq 2$. The two excluded minors are the wheel on $5$ vertices and the graph obtained by gluing two copies of $K_4$ along an edge and then deleting that edge. We also show that the same two graphs are the complete set of excluded minors for $f_1(G) \leq 2$. In addition, we give a family of examples that show that $f_\infty$ is unbounded on the class of planar graphs and $f_\infty$ is not bounded as a function of tree-width.

description: Quite different R&D lag structures predominate in studies of agricultural R&D compared with studies of R&D in other industries, and compared with studies of economic growth more broadly. Here we compare the main models and their implications using long-run data for U.S. agriculture. We reject the models predominantly used in studies of economic growth and industrial R&D both on prior grounds and using various statistical tests. The preferred model is a 50-year gamma lag distribution model. The estimated elasticity of MFP with respect to the knowledge stock is 0.28 and the implied marginal benefit-cost ratio is 23:1.

description: Recent Cosmic Microwave Background (CMB) temperature and polarization anisotropy measurements from the Planck mission have significantly improved previous constraints on the neutrino masses as well as the bounds on extended models with massless or massive sterile neutrino states. However, due to parameter degeneracies, additional low redshift priors are mandatory in order to sharpen the CMB neutrino bounds. We explore here the role of different priors on low redshift quantities, such as the Hubble constant, the cluster mass bias, and the reionization optical depth $τ$. Concerning current priors on the Hubble constant and the cluster mass bias, the bounds on the neutrino parameters may differ appreciably depending on the choices adopted in the analyses. With regard to future improvements in the priors on the reionization optical depth, a value of $τ=0.05\pm 0.01$, motivated by astrophysical estimates of the reionization redshift, would lead to $\sum m_ν<0.0926$~eV at $90\%$~CL, when combining the full \textit{Planck} measurements, Baryon Acoustic Oscillation and Planck clusters data, thereby opening the window to unravel the neutrino mass hierarchy with existing cosmological probes.

description: We show the three-dimensional electronic structure of the Kondo lattice CeIn3 using soft x-ray angle resolved photoemission spectroscopy in the paramagnetic state. For the first time, we have directly observed the three-dimensional topology of the Fermi surface of CeIn3 by photoemission. The Fermi surface has a complicated hole pocket centred at the Γ-Z line and an elliptical electron pocket centred at the R point of the Brillouin zone. Polarization and photon-energy dependent photoemission results both indicate the nearly localized nature of the 4f electrons in CeIn3, consistent with the theoretical prediction by means of the combination of density functional theory and single-site dynamical meanfield theory. Those results illustrate that the f electrons of CeIn3, which is the parent material of CeMIn5 compounds, are closer to the localized description than the layered CeMIn5 compounds.

description: We discover novel topological effects in the one-dimensional Kitaev chain modified by long-range Hamiltonian deformations in the hopping and pairing terms. This class of models display symmetry-protected topological order measured by the Berry/Zak phase of the lower band eigenvector and the winding number of the Hamiltonians. For exponentially-decaying hopping amplitudes, the topological sector can be significantly augmented as the penetration length increases, something experimentally achievable. For power-law decaying superconducting pairings, the massless Majorana modes at the edges get paired together into a massive non-local Dirac fermion localised at both edges of the chain: a new topological quasiparticle that we call topological massive Dirac fermion. This topological phase has fractional topological numbers as a consequence of the long-range couplings. Possible applications to current experimental setups and topological quantum computation are also discussed.

On the self-similarity of nonhelical magnetohydrodynamic turbulence

description: We re-analyze the Olesen arguments on the self-similarity properties of freely evolving, nonhelical magnetohydrodynamic turbulence. We find that a necessary and sufficient condition for the kinetic and magnetic energy spectra to evolve self-similarly is that the initial velocity and magnetic field are not homogeneous functions of space of different degree, to wit, the initial energy spectra are not simple powers of the wavenumber with different slopes. If, instead, they are homogeneous functions of the same degree, the evolution is self-similar, it proceeds through selective decay, and the order of homogeneity fixes the exponents of the power laws according to which the kinetic and magnetic energies and correlation lengths evolve in time. If just one of them is homogeneous, the evolution is self-similar and such exponents are completely determined by the slope of that initial spectrum which is a power law. The latter evolves through selective decay, while the other spectrum may eventually experience an inverse transfer of energy. Finally, if the initial velocity and magnetic field are not homogeneous functions, the evolution of the energy spectra is still self-similar but, this time, the power-law exponents of energies and correlation lengths depend on a single free parameter which cannot be determined by scaling arguments. Also in this case, an inverse transfer of energy may in principle take place during the evolution of the system.
