Self-consistent nonperturbative anomalous dimensions

Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A self-consistent treatment of two and three point functions in models with trilinear interactions forces them to have opposite anomalous dimensions. We indicate how the anomalous dimension can be extracted nonperturbatively by solving and suitably truncating the topologies of the full set of Dyson-Schwinger equations. The first step requires a sensible ansatz for the full vertex part which conforms to first order perturbation theory at least. We model this vertex to obtain typical transcendental equations between anomalous dimension and coupling constant $g$ which coincide with know results to order $g^4$.

The Effect of Massive Neutrinos on the Halo Spin Flip Phenomenon

description: The halo spin flip refers to the phenomenon that the spin axes of dark matter halos with masses above a certain threshold tend to be preferentially aligned perpendicular to the hosting large-scale filaments, while low-mass halos tend to have their spin axes aligned parallel to such structures. Extensive work has so far been conducted to understand this phenomenon under the assumption of cold dark matter and suggested that its origin should be closely related to the nonlinear evolution of the halo angular momentum in the anisotropic cosmic web. We present, for the first time, a numerical examination of this phenomenon assuming the presence of massive neutrinos, finding a clear and robust dependence of the threshold mass for the spin flip on the total neutrino mass. Our physical explanation is that the presence of more massive neutrinos retard the nonlinear evolution of the cosmic web, which in turn allows the halo spin vectors to better retain their memories of the initial tidal interactions in the nonlinear regime. Our finding implies that the statistical alignment of halo spins with the large-scale structures can be in principle used as a probe of the total neutrino mass.

Absence of hole pairing in a simple t-J model on the Shastry-Sutherland lattice

description: The Shastry-Sutherland model is a two-dimensional frustrated spin model whose ground state is a spin gap state. We study this model doped with one and two holes on a 32-site lattice using exact diagonalization. When t'>0, we find that the diagonal dimer order that exists at half-filling are retained at these moderate doping levels. No other order is found to be favored on doping. The holes are strongly repulsive unless the hopping terms are unrealistically small. Therefore, the existence of a spin gap at half-filling does not guarantee hole-pairing in the present case.

description: Light wave-packets propagating from the Earth to satellites will be deformed by the curved background spacetime of the Earth, thus influencing the quantum state of light. We show that Gaussian coherence of photon pairs, which are initially prepared in a two-mode squeezed state, is affected by the curved spacetime background of the Earth. We demonstrate that quantum coherence of the state increases for a specific range of height h and then gradually approaches a finite value with further increasing height of the satellite's orbit in Kerr spacetime, because special relativistic effect are involved. Meanwhile, we find that Gaussian coherence increases with the increase of Gaussian bandwidth parameter, but the Gaussian coherence decreases with the growth of the peak frequency. In addition, we also find that total gravitational frequency shift causes changes of Gaussian coherence less than $%1$ and different initial peak frequencies also can effect rate of change with the satellite height in geostationary Earth orbits.

Our results for the pure limit yield values of the the critical temperature and the critical exponent $ν$ in excellent agreement with previous high precision studies. In the disordered case, a mixed "chiral" phase is found which may be in the same universality class as 3d Heisenberg spin glasses.

description: The nuclear recoil effect on the $^2 P_{3/2}$-state $g$ factor of B-like ions is calculated to first order in the electron-to-nucleus mass ratio $m/M$ in the range $Z=18$--$92$. The calculations are performed by means of the $1/Z$ perturbation theory. Within the independent-electron approximation, the one- and two-electron recoil contributions are evaluated to all orders in the parameter $αZ$ by employing a fully relativistic approach. The interelectronic-interaction correction of first order in $1/Z$ is treated within the Breit approximation. Higher orders in $1/Z$ are partially taken into account by incorporating the screening potential into the zeroth-order Hamiltonian. The most accurate to date theoretical predictions for the nuclear recoil contribution to the bound-electron $g$ factor are obtained.

Social Impact Investing and the changing face of conservation finance
Creators: name: Olmsted, Paige
Publisher: name: The University of British Columbia
Year: 2018

description: A consistent and significant challenge facing the conservation of natural resources is where the money will come from, and what new sources will arise as trusted sources dry up? While roughly US$30B is spent on conservation efforts globally per annum, the annual need to maintain critical ecosystem functions in the long term is estimated to be ten times higher. In an era where public support is increasingly insufficient, social impact investing is one funding strategy garnering attention in the policy sphere. Social impact investing directs capital to organizations, funds, and projects that generate both social and financial returns. Banks and investment firms, along with foundations and governments, are increasingly interested in the potential for novel financial arrangements to direct more funding toward critical social challenges, including environmental and conservation issues. Existing impact funds and initiatives demonstrate how billions can be leveraged to support projects ranging from healthcare to poverty alleviation to infrastructure, and highlight the opportunity for similar models to generate financial support for conservation objectives without undermining fundamental ecological goals. Ecological conservation has not yet been a focal point in the impact investing space, but current research and reporting suggests there is available capital as well as a substantial need for funding. While several billion dollars are currently invested as impact capital in conservation-related programs, in the next decade dramatic increases in this area are anticipated. The extent of this expansion, and the effectiveness of these funds in achieving real conservation gains, will rely upon appropriate investment vehicles being available and, importantly on the engagement of conservation community. Both will require education, coordination, and leadership on the part of conservation organizations, investors, and organizations serving intermediary roles. Not all conservation programs are appropriate for this type of financing. Here we provide an explanation of current actors in the conservation impact arena as well as critical features and requisite data to consider feasibility. Though conservation receives a relatively small percentage of philanthropic giving as compared to health and poverty related social causes, there are challenges unique to the practice of natural resources conservation that may explain in part why conservation thus far represents a small percentage of overall impact investing as compared to other sectors. These challenges include reliable risk assessment, consistent and comparable impact measurement, and (where applicable) generating competitive economic returns. To address these challenges, ... key recommendations [are proposed].

description: We study the effect of spin-orbit coupling on quantum gates produced by pulsing the exchange interaction between two single electron quantum dots. Spin-orbit coupling enters as a small spin precession when electrons tunnel between dots. For adiabatic pulses the resulting gate is described by a unitary operator acting on the four-dimensional Hilbert space of two qubits. If the precession axis is fixed, time-symmetric pulsing constrains the set of possible gates to those which, when combined with single qubit rotations, can be used in a simple CNOT construction. Deviations from time-symmetric pulsing spoil this construction. The effect of time asymmetry is studied by numerically integrating the Schrödinger equation using parameters appropriate for GaAs quantum dots. Deviations of the implemented gate from the desired form are shown to be proportional to dimensionless measures of both spin-orbit coupling and time asymmetry of the pulse.

description: Topological lasers are of growing interest as a way to achieve disorder-robust single mode lasing using arrays of coupled resonators. We study lasing in a two-dimensional coupled resonator lattice exhibiting transitions between trivial and topological phases, which allows us to systematically characterize the lasing modes throughout a topological phase. We show that, unlike conventional topological robustness that requires a sufficiently large bulk band gap, bifurcations in topological edge mode lasing can occur even when the band gap is maximized. We show that linear mode bifurcations from single mode to multi-mode lasing can occur deep within the topological phase, sensitive to both the pump shape and lattice geometry. We suggest ways to suppress these bifurcations and preserve single edge mode lasing.

description: This paper associates a dual problem to the minimization of an arbitrary linear perturbation of the robust sum function introduced in DOI 10.1007/s11228-019-00515-2. It provides an existence theorem for primal optimal solutions and, under suitable duality assumptions, characterizations of the primal-dual optimal set, the primal optimal set, and the dual optimal set, as well as a formula for the subdiffential of the robust sum function. The mentioned results are applied to get simple formulas for the robust sums of subaffine functions (a class of functions which contains the affine ones) and to obtain conditions guaranteeing the existence of best approximate solutions to inconsistent convex inequality systems.

Isotopically engineered silicon nanostructures in quantum computation and communication

description: Natural silicon consists of three stable isotopes with atomic mass 28 (92.21%), 29 (4.70%) and 30 (3.09%). To present day, isotopic enrichment of Si was used in electronics for two goals: (i) fabrication of substrates with high level of doping and homogeneous distribution of impurities and (ii) for fabrication of substrates with enhanced heat conduction which allows further chips miniaturization. For the first purpose, enrichment of Si with Si-30 is used, because after irradiation of a Si ingot by the thermal neutron flux in a nuclear reactor, this isotope transmutes into a phosphorus atom which is a donor impurity in Si. Enrichment of Si with Si-30 allows one to increase the level of doping up to a factor of 30 with a high homogeneity of the impurity distribution. The second purpose is achieved in Si highly enriched with isotope Si-28, because mono-isotopic Si is characterized by enhanced thermal conductivity. New potential of isotopically engineered Si comes to light because of novel areas of fundamental and applied scientific activity connected with spintronics and a semiconductor-based nuclear spin quantum computer where electron and/or nuclear spins are the object of manipulation. In this case, control of the abundance of nuclear spins is extremely important. Fortunately, Si allows such a control, because only isotope Si-29 has a non-zero nuclear spin. Therefore, enrichment or depletion of Si with isotope Si-29 will lead to the creation of a material with a controlled concentration of nuclear spins. Two examples of nano-devices for spintronics and quantum computation, based on isotopically engineered silicon, are discussed.

Measurements of the Size Distribution and Aerodynamic Properties of Soot
Creators: name: Cleary, Thomas George
Publisher: name: Digital Repository at the University of Maryland
Year: 1989

description: The particle size distribution and aerodynamic properties of soot agglomerates formed by the combustion of acetylene is studied. A positive pressure soot generator was constructed which allowed for the characterization of the soot aerosol. Nearly monodisperse particles (10 to 20 nm in diameter) have been observed at low acetylene flow rates. The mean size and width of the distribution are confirmed with a diffusion battery and a differential mobility analyzer. Size distribution measurements of soot agglomerates have been obtained from optical and electron microscopy for a range of acetylene flow rates. The electron microscopy results are compared to model predictions of the cluster size distribution. Friction coefficient measurements from electrical mobility classified agglomerates have been made and are compared to fractal models for clusters. Aerodynamic diameters of impacted agglomerates are related to the geometric mean size form optical microscopy. These results suggest that the geometric mean size can replace the spherical diameter if a particle density of 0.1 g/cc is assumed.
Perspectives of family caregivers on care of hospitalized relatives with dementia

Year: 2016

description: Purpose - To examine family caregivers’ experiences of care provision for their hospitalized relative with dementia Methods – An integrative literature review was conducted using healthcare databases to examine primary research that focused specifically on family caregivers’ attitudes and experiences of care that was provided to their relatives with dementia in the acute care setting. Significance – Family caregivers were overall dissatisfied with the care that was provided to their relatives with dementia in the acute care setting. As a result, family caregivers felt it was their responsibility to provide personal care to their relatives with dementia and ensure that they were safe. There were three major themes that emerged as barriers to providing optimal care and person-centered care (PCC) to the patient with dementia: communication, knowledge and the environment. The concept of (PCC) is identified as the gold standard approach to care for dementia patients. There is evidence of family caregivers’ expressing satisfaction where this philosophy of care is applied in the acute care setting. It is imperative that all stakeholders involved in the care of the dementia patient to collaborate to ensure a change for the better in care provision. This will be possible with effective communication between all stakeholders, educating and training the nurses in dementia care and also making physical changes to the acute care environment and its process to create a culture of PCC for the dementia patient.

description: The Leibniz bracket of an operator on a (graded) algebra is defined and some of its properties are studied. A basic theorem relating the Leibniz bracket of the commutator of two operators to the Leibniz bracket of them, is obtained. Under some natural conditions, the Leibniz bracket gives rise to a (graded) Lie algebra structure. In particular, those algebras generated by the Leibniz bracket of the divergence and the Laplacian operators on the exterior algebra are considered, and the expression of the Laplacian for the product of two functions is generalized for arbitrary exterior forms.

description: Disc-driven migration is a key evolutionary stage of supermassive black-hole binaries hosted in gas-rich galaxies. Besides promoting the inspiral, viscous interactions tend to align the spins of the black holes with the orbital angular momentum of the disc. We present a critical and systematic investigation of this problem, also known as the Bardeen-Petterson effect. We design a new iterative scheme to solve the non-linear dynamics of warped accretion discs under the influence of both relativistic frame dragging and binary companion. We characterize the impact of the disc "critical obliquity", which marks regions of the parameter space where stationary solutions do not exist. We find that black-hole spins reach either complete alignment or a critical configuration. Reaching the critical obliquity might imply that the disc breaks as observed in hydrodynamical simulations. Our findings are important to predict the spin configurations with which supermassive black-hole binaries enter their gravitational-wave driven regime and become detectable by LISA.

 COMMENTS. Although type material of D. michoacanensis has not been examined, its original description and illustration closely match Brazilian puparia of Aleuroplatus denticulatus Bondar in BMNH (probably syntypes, Martin, 2004: 560); they also share their host plant genus, Ficus, and are therefore considered synonymous. Also, examination of Bondar’s material of A. denticulatus indicates that this species should be transferred to Dialeurodes.
 Jensen (1999) recognised what he termed the D. michoacanensis species­group, with D. michoacanensis Sampson & Drews and D. egregissima S.& D. sharing the unusual presence of a ventral band of spinules between the puparial mouthparts and antennae. However, the puparium of D. egregissima has its transverse and longitudinal moulting sutures with their distal extremities joined by a cephalothoracic suture (see figure A, p. 5), forming a pair of plates which are lost when the adult insect emerges; this character has been regarded as having generic significance (e.g. the Asian genus, Cockerelliella Sundararaj & David, 1992), and yet the moulting sutures of D. denticulatus are typical for Dialeurodes. Until the relative importance of this character is investigated in more detail D. egregissima, and a similar species from Belize (species 8, Appendix 1), are here retained within Dialeurodes sensu lato.
 A number of puparia collected from avocado (Persea americana), in both Belize and Nicaragua, share the following characters with D. denticulatus collected from species of Ficus: ventral spinule band present between antennae, the same chaetotaxy with capitate dorsal setae, and a cluster of a few tiny pale tubercles present at mesal margin of each thoracic and caudal tracheal marginal indentation. The dorsal surfaces of puparia from avocado are more coarsely tuberculate than in most specimens from Ficus species, but the submedian zone is delineated in the same way. It is considered most likely that the avocado specimens are a variant of D. denticulatus, especially given that there is also a degree of variation shown in the degree of roughening of the dorsal puparial surfaces of specimens collected from different species of Ficus.

description: Adoption of stall feeding (SF) as well as choices of animals and seasons for its application were assessed in northern Ethiopia in 2015 using a household field survey. The study was conducted in 21 communities to account for differences in agro ecology and to better understand the adoption process. A Heckman selection model was used to estimate adoption and extent of adoption based on a model of technology adoption within an agricultural household framework. A Poisson model was also applied to explain the number of SF adopting seasons. Further a multinomial logit model was estimated in order to reinforce understanding of the choices. The purpose of this study was to understand the driving factors of full or seasonal SF adoption and its intensity as well as animal and seasonal choices. The study results indicate that farmers actually practicing SF in a full year are 36% while those of actual seasonal adopters are 55.6%. The choice of animals allocated to SF include cow (40%), ox (31%) and other animals (29%) of the given sample indicating feeding cow under SF takes the largest share. Similarly, the choice for season were, 65% full year, 29 % wet (summer and autumn) and 6% dry (winter and spring), implying that more than half of the sample farmers practice SF the year round. Empirical results of this study showed that result is in favour of the Boserupian hypothesis indicating that small grazing land and large exclosure are associated with a higher probability of use of SF and with a higher number of SF adopting seasons throughout the year. In a similar vein, small average village farm size stimulated full SF adoption and SF adopting seasons, Availability of labour relative to farm size and a number of breed cows significantly increased the probability of using SF by 0.01% and 66% respectively. While animal shock appeared to have a marginal effect of 14%.The finding also revealed that factors such as access to information and early exposure increased the probability of SF adoption by 18% and 6%. Similarly, the positive marginal effect of real milk price is 15%. However, SF appears to be less attractive to those farmers with more herd size relative farm size and less crop residue. Regarding the intensity of SF adoption, while total labour time, farm size positively affect the extent of SF adoption, total herd size and grazing land ratio negatively influence farmers’ extent of SF adoption in all seasons.

description: Horticultural farms in Germany face substantial business risks. However, fruit farms often struggle to implement appropriate risk management processes, and the risk management literature widely has ignored this farm type. The aim of the study was to improve the assessment of risks by farmers and the choice of suitable risk management instruments. Therefore, a risk management process based on subjective probabilities and suitable for small and medium-sized farms was developed, considering the specific needs of family run businesses. An online survey was conducted to achieve a comprehensive view of the risk perception and risk management practices of German fruit producers. Price and production risks are the most relevant risk categories for fruit farmers. However, among single risk sources, those in the people risk category were seen as the most important. Results show significant interactions among risk categories and a significant correlation between loss experience and the rating of risk categories. The assumption that risk averse farmers generally rate risks higher than risk neutral or risk seeking farmers cannot be confirmed. Diversification seems to be the most important risk management instrument for many fruit producers, especially diversification of marketing channels, farm income, and production activities. Further research should focus on the apparent inconsistency between the satisfaction with instruments reported by farmers and the actual implementation of many of them (e.g., hail insurance and anti-hail net). Furthermore, there is a need for research, to develop decision models considering the interactions of risks and risk management instruments, loss experience and risk seeking attitudes.

description: We calculate the massive polarized three-loop pure singlet operator matrix element $A_{Qq}^{(3), \rm PS}$ in the single mass case in the Larin scheme. This operator matrix element contributes to the massive polarized three-loop Wilson coefficient $H_{Qq}^{(3),\rm PS}$ in deep-inelastic scattering and constitutes a three-loop transition matrix element in the variable flavor number scheme. We provide analytic results in Mellin $N$ and in $x$ space and study the behaviour of this operator matrix element in the region of small and large values of the Bjorken variable $x$.

description: The Common Agricultural Policy (CAP) is at the crossroads of several policy interests. It is scrutinised by farming and environmental communities as well as by the food industry, regional authorities, research and public sector. The paper analyses the recent consultation process undertaken by the European Commission. The paper concludes that among the key reform issues are: the level of the financial support to the CAP; the continued environmental and other public goods orientation of the CAP and generational renewal. In addition, the focus on result orientation and reduction of the administrative burden can be expected. The relevant European Commission proposals are foreseen around summer 2018.

Pattern Speeds of BIMA-SONG Galaxies with Molecule-Dominated ISMs Using the Tremaine-Weinberg Method
Creators: name: Rand, Richard J.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We apply the Tremaine-Weinberg method of pattern speed determination to data cubes of CO emission in six spiral galaxies from the BIMA SONG survey each with an ISM dominated by molecular gas. We compare derived pattern speeds with estimates based on other methods, usually involving the identification of a predicted behavior at one or more resonances of the pattern(s). In two cases (NGC 1068 and NGC 4736) we find evidence for a central bar pattern speed that is greater than that of the surrounding spiral and roughly consistent with previous estimates. However, the spiral pattern speed in both cases is much larger than previous determinations. For the barred spirals NGC 3627 and NGC 4321, the method is insensitive to the bar pattern speed (the bar in each is nearly parallel to the major axis; in this case the method will not work), but for the former galaxy the spiral pattern speed found agrees with previous estimates of the bar pattern speed, suggesting that these two structures are part of a single pattern. For the latter, the spiral pattern speed found is in agreement with several previous determinations. For the flocculent spiral NGC 4414 and the ``Evil Eye'' galaxy NGC 4826, the method does not support the presence of a large-scale coherent pattern. We also apply the method to a simulated barred galaxy in order to demonstrate its validity and to understand its sensitivity to various observational parameters. In addition, we study the results of applying the method to a simulated, clumpy axisymmetric disk with no wave present. The TW method in this case may falsely indicate a well-defined pattern.

description: This review is intended for readers who want to have a quick understanding on the theoretical underpinnings of coherent states and squeezed states which are conventionally generated from the prototype harmonic oscillator but not always restricting to it. Noting that the treatments of building up such states have a long history, we collected the important ingredients and reproduced them from a fresh perspective but refrained from delving into detailed derivation of each topic. By no means we claim a comprehensive presentation of the subject but have only tried to re-capture some of the essential results and pointed out their inter-connectivity.

description: The jets of microquasars with high-mass stellar companions are exposed to the dense matter field of the stellar wind. We present estimates of the gamma-ray emission expected from the jet-wind hadronic interaction and we discuss the detectability of the phenomenon at high energies. The proposed mechanism could explain some of the unidentified gamma-ray sources detected by EGRET instrument on the galactic plane.

description: The study was designed to investigate the impact of flower cultivation on farmers’ livelihood in Jhenaidah district of Bangladesh. For this purpose, primary data were collected from 115 flower cultivators and 45 controls from February to March, 2017. Descriptive statistics, step wise regression and Constraints Facing Index (CFI) were used for analysing data. Result shows that most of the farmers (76.5%) gained medium livelihood improvement through flower cultivation, while 13.9 percent had high impact of flower cultivation on their livelihood. Among the entire variables- attitude towards flower cultivation alone contribute 39.5 percent of the variation of the impact. The Majority (73.9%) of the flower farmers had medium constraints in flower cultivation. As per Constraint Faced Index (CFI) high labour wages positioned the first place as the constraints of flower cultivation. But the composite impact of flower cultivation on farmers’ livelihood was moderate. Respective authorities like DAE, NGOs should implement and popularize flower cultivation project on a massive scale for improving farmers’ livelihood.

description: Farmers and their technology remain central to national food security and agricultural development in Nigeria. There is growing concern that the technologies used by farmers for storage and preservation of arable crops may constitute impediments to rural agricultural development. The study assessed farmers' utilization of indigenous storage and preservation technologies for arable crops with a view to expanding technology options. Multi-staged sampling procedure was used to obtain data from 240 practicing arable crop farmers. The results revealed that 15 technologies were utilised with variations between crops and gender. The constraints to technology utilisation and reasons for usage were also identified. Results of regression analysis revealed that years of formal education, years of farming experience and farm size significantly influenced technology utilization in arable crops in Nigeria. There was a low extent of utilization and most farmers were dissatisfied with indigenous technologies despite few available alternatives.

description: We have carried out numerical simulations of shot noise in 2D arrays of single-electron islands with random background charges. The results show that in contrast with the 1D arrays, at low currents the current noise is strongly colored, and its spectral density levels off at very low frequencies. The Fano factor may be much larger than unity, due to the remnants of single-electron/hole avalanches. However, even very small thermal fluctuations reduce the Fano factor below 1 for almost any bias.
