The shifting of the corporation income tax : theory and evidence
Creators: name: Wickham, Peter Hugh
Publisher: name: University of British Columbia
Year: 2011

description: Over the last ten years a series of empirical studies have been published that claim to test by statistical methods whether corporations, faced with the imposition of a tax on their business income, can in the short-term increase the gross profits so as to maintain their net of tax rate of return on capital. These studies have used various methods but the results yield contradictory evidence as to whether the proposition could or could not be accepted as having validity. The results suggested that a fresh look at the theoretical analysis on the corporate tax be undertaken. The methodology followed was to make a series of simplifying assumptions such that focus could be directed towards an examination of decision-making within the firm and within the industry on which the tax was imposed. For the firm the effective rate of tax is dependent not only upon the statutory rate of tax but also upon the depreciation provisions in force; with an effective tax rate greater than zero, the tax ceteris paribus reduces the rate of return on investment projects. However, it was found that to gain fuller results as to the effect of the tax, more detailed specification of the environment within which the firm operates is needed. The classical models of pure competition and pure monopoly were studied; short-run profit maximisation is assumed in such models. The tax imposition led to the prediction that the after-tax rate of return fell in the short-run; in the long-run if the tax imposed on normal profits, capital moved out of the industry. Consideration was then given to oligopolistic industries. Profit maximisation was still assumed, but with the realisation that over the planning horizon the firm, departures from full short-run profit maximisation were probable. The reasons for such behaviour were examined. The tax was then imposed. In particular cases the tax affected the constraints to allow price increases and an increase in the gross rate of return. In others the constraints remained unchanged and no short-run alleviating action was possible. Relaxation of the assumptions of the theoretical analysis was then allowed, so that testable predictions could be put forward. Several of the recent studies were then examined to see whether their framework, data and estimating equations were adequate to test the hypotheses put forward. The conclusion drawn was that the use of annual time series over forty years was inadequate for such a purpose.

description: In this paper we exploit two equivalent formulations of the average rate of material entropy production in a planetary system to propose an approximate splitting between contributions due to vertical and eminently horizontal processes. Our approach is based only upon 2D radiative fields at the surface and at the top of atmosphere of a general planetary body. Using 2D fields at the top of atmosphere alone, we derive lower bounds to the rate of material entropy production and to the intensity of the Lorenz energy cycle. By introducing a measure of the efficiency of the planetary system with respect to horizontal thermodynamical processes, we provide insight on a previous intuition on the possibility of defining a baroclinic heat engine extracting work from the meridional heat flux. The approximate formula of the material entropy production is verified and used for studying the global thermodynamic properties of climate models (CMs) included in the PCMDI/CMIP3 dataset in pre-industrial climate conditions. It is found that about 90% of the material entropy production is due to vertical processes such as convection, whereas the large scale meridional heat transport contributes only about 10%. The total material entropy production is typically 55 mWK-1m-2, with discrepancies of the order of 5% and CMs' baroclinic efficiencies are clustered around 0.055. When looking at the variability and co-variability of the considered thermodynamical quantities, the agreement among CMs is worse, suggesting that the description of feedbacks is more uncertain.

description: We report on the results of an optical spectroscopic survey designed to confirm the youth and determine the spectral types among a sample of young stellar object (YSO) candidates in the Serpens Molecular Cloud. We observed 150 infrared excess objects, previously discovered by the Spitzer Legacy Program "From Molecular Cores to Planet-Forming Disks" (c2d), bright enough for subsequent Spitzer/IRS spectroscopy. We obtained 78 optical spectra of sufficient S/N for analysis. Extinctions, effective temperatures and luminosities are estimated for this sample, and used to construct H-R diagrams for the population. We identified 20 background giants contaminating the sample, based on their relatively high extinction, position in the H-R diagram, the lack of Halpha emission and relatively low infrared excess. Such strong background contamination (25%) is consistent with the location of Serpens being close to the Galactic plane (5degrees Galactic latitude). The remaining 58 stars (75%) were all confirmed to be young, mostly K and M-type stars that are presumed to belong to the cloud. Individual ages and masses for the YSOs are inferred based on theoretical evolutionary models. The models indicate a spread in stellar ages from 1 to 15 Myr, peaking at 2 - 6 Myr, and a mass distribution of 0.2 to 1.2 Msun with median value around 0.8 Msun. Strong H emission lines (EW[Halpha] > 3 A) have been detected in more than half of the sample (35 stars). The mass accretion rates as derived from the H line widths span a broad distribution over 4 orders of magnitude with median accretion rate of 10^-8 Msun/yr. Our analysis shows that the majority of the infrared excess objects detected in Serpens are actively accreting, young T-Tauri stars.

Athenaios Mechanicus
Creators: name: West, George Robert

Year: 2011

description: The work of Athenaios Mechanicus is a little known treatise on siege machinery entitled ∏ερì Μηχαѵηµάτωѵ . Although this work, along with others on the same topic, is contained in several manuscripts, during the last 250 years very little study has been devoted to it. There have been three editions (Thévenot, 1693; Wescher; 1867; and Schneider 1912) and two translations, one in French (De Rochas, 1884) and one in German (Schneider, 1912). Schneider has also written a commentary. Biographical information is very slight and scholars who have tried to date the work have arrived at widely varying conclusions (third century B.C. to third century after Christ). In this thesis my objects have been: a) to provide an English translation of the work based on Wescher’s text, b) to provide a brief résumé of the opinions advanced concerning the biography of Athenaios and his relationship to Vitruvius, c) to write a brief commentary on selected topics arising from the text.

description: We report on experiments in which magnetically driven radiatively cooled plasma jets were produced by a 1 MA, 250 ns current pulse on the MAGPIE pulsed power facility. The jets were driven by the pressure of a toroidal magnetic field in a ''magnetic tower'' jet configuration. This scenario is characterized by the formation of a magnetically collimated plasma jet on the axis of a magnetic ''bubble'', confined by the ambient medium. The use of a radial metallic foil instead of the radial wire arrays employed in our previous work allows for the generation of episodic magnetic tower outflows which emerge periodically on timescales of ~30 ns. The subsequent magnetic bubbles propagate with velocities reaching ~300 km/s and interact with previous eruptions leading to the formation of shocks.

description: A considerable effort has recently gone into the study of Gaussianity of cosmic microwave background (CMB) data. Among such attempts, there is one with two non-Gaussianity indicators, proposed by the authors, and used in a search for significant deviation from Gaussianity in the WMAP internal linear combination (ILC) and in the single frequency WMAP maps with the KQ75 mask. Here we extend and complement these results by performing a similar analysis for the de Oliveira-Costa and Tegmark (OT) WMAP three-year $KQ75$ masked map, in which the foreground is reduced through a different statistical cleaning procedure.

Archaeological investigations at Nootka Sound, Vancouver Island.
Creators: name: McMillan, Alan D.
Publisher: name: University of British Columbia
Year: 2011

description: The archaeology of the Moachat Nootka territory, consisting of Nootka Sound and Tahsis and Tlupana Inlets, was chosen as the specific concern of this thesis. Nootka Sound was an important area in the early historic fur trade and a great deal was written by the early explorers and traders about the inhabitants of this region. However, little archaeological work has been done. A large-scale excavation, carried out at the main Moachat village of Yukwot in 1966 by the National Historic Parks Branch, was the only previous archaeological project. As the material obtained by this excavation had not been published or fully processed at the time of writing, very little of the information was available for the present study. The objectives of the fieldwork were: to visit and describe the sixteen villages and camp sites listed for the Moachat by Drucker (1951: 229), to carry out excavations at one of these sites, to visit and describe the burial caves and pictographs which were known to exist in the area, and to collect whatever ecological and ethnographic information could be conveniently obtained. No site survey was undertaken, although a few previously unrecorded sites were discovered. Excavations were carried out at Coopte (DkSp 1), the winter village of the Moachat, during the summer of 1968. The excavations were rather small in scope, lasting only two months and being conducted sometimes by myself only and sometimes with the help of one assistant. Nevertheless, fifteeen test pits were excavated which yielded 273 artifacts and a fair sample of faunal remains and historic material. This paper includes an account of the excavations at Coopte, as well as descriptions of the other sites visited. It is also an attempt to integrate historic and ethnographic information with the archaeological data. The substantial body of published and unpublished information provides a convenient basis for the interpretation of the archaeological material. It is hoped that this approach will prove useful in attempting to describe the way of life of the aboriginal inhabitants of Nootka Sound.
The Feasibility of Interference Alignment over Measured MIMO-OFDM Channels

description: Interference alignment (IA) has been shown to achieve the maximum achievable degrees of freedom in the interference channel. This results in sum rate scaling linearly with the number of users in the high signal-to-noise-ratio (SNR) regime. Linear scaling is achieved by precoding transmitted signals to align interference subspaces at the receivers, given channel knowledge of all transmit-receive pairs, effectively reducing the number of discernible interferers. The theory of IA was derived under assumptions about the richness of scattering in the propagation channel; practical channels do not guarantee such ideal characteristics. This paper presents the first experimental study of IA in measured multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) interference channels. Our measurement campaign includes a variety of indoor and outdoor measurement scenarios at The University of Texas at Austin. We show that IA achieves the claimed scaling factors, or degrees of freedom, in several measured channel settings for a 3 user, 2 antennas per node setup. In addition to verifying the claimed performance, we characterize the effect of Kronecker spatial correlation on sum rate and present two other correlation measures, which we show are more tightly related to the achieved sum rate.

description: The paper presents a new stiffness modelling method for multi-chain parallel robotic manipulators with flexible links and compliant actuating joints. In contrast to other works, the method involves a FEA-based link stiffness evaluation and employs a new solution strategy of the kinetostatic equations, which allows computing the stiffness matrix for singular postures and to take into account influence of the internal forces. The advantages of the developed technique are confirmed by application examples, which deal with stiffness analysis of the Orthoglide manipulator.

description: We extend the analysis of the recently obtained stringy cosmological solutions induced by thermal and quantum effects, once space-time supersymmetry is spontaneously broken by geometrical fluxes. Cases in which more than one modulus participating in the supersymmetry breaking mechanism are investigated. The free energy is obtained at the full string level. In the intermediate cosmological region where the temperature and the supersymmetry breaking scale are sufficiently smaller than the Hagedorn temperature, the quantum and thermal corrections are under control and calculable. The reason is that the contributions to the effective potential of the moduli that are not participating in the supersymmetry breaking are exponentially suppressed. The backreaction on the initially flat background results in many cases into cosmological evolutions, where the dynamics of all complex structure moduli is frozen. The solutions describe effectively a radiation dominated era, where thermal effects are never negligible, even if the temperature tends to zero at late times. We analyze several types of supersymmetry breaking patterns and examine the stability of the corresponding radiation era.

Publisher: name: The Science world a Monthly e magazine

description: Fusarium wilt is a common plant disease brought on by several strains of the fungus Fusarium oxysporum, which lives in the soil as well as in seeds of the host crop plants. Numerous plant species, including commercially significant food crops like Banana and pulse crops like Chickpeas, are vulnerable. As the pathogen is typically a soil borne type and it can survive in soil for several years, the development and cultivation of resistant variety of crop plant is an efficient way to overcome the yield loss brought on by Fusarium wilt. Thus, researchers across the world are working continuously to develop the crop plants resistant against different strains of F. oxysporum. However, in order to develop resistant crop plants, it is inevitable to understand the host pathogen interaction and molecular basis of resistance mechanism. This popular article highlights the important aspects F. oxysporum specific host pathogen interaction and general molecular mechanisms involved during F. oxysporum specific signal perception and resistance response by the host plants

description: To clarify the outstanding problem in charmonium production that existing theories cannot explain the observed cross sections of $χ_{cJ}$ (J=0,1,2) and ratio $R_{χ_c}=σ_{χ_{c2}}/σ_{χ_{c1}}\approx 0.75$ (in contrast to the spin counting value 5/3) at the Tevatron, we study the complete next-to-leading order radiative corrections in nonrelativistic QCD, and find next-to-leading order contributions of $^3P_J^{[1]}$ are more important than leading order at high $p_T$, and $^3P_1^{[1]}$ decreases slower than $^3P_2^{[1]}$, implying a natural explanation for the $R_{χ_c}$ puzzle. By fitting $R_{χ_c}$, the predicted cross sections of $χ_{cJ}$ are found to agree with data. The result indicates color-octet contribution is crucially needed, thus providing a unique test for heavy quarkonium production mechanisms. Feed-down contributions of $χ_{cJ}$ to prompt $J/ψ$ production are estimated to be substantial, about $30-40%$ at $p_T=20$ GeV. Production of $χ_{cJ}$ (J=0,1,2) at the LHC is also predicted.

В работе дана характеристика основных правовых аспектов в области осуществления международного инвестиционного сотрудничества США и Китая. Проанализированы объем и динамика притока мировых ПИИ в экономику США и КНР, а также проведен анализ их взаимного инвестирования по отраслям экономики. В статье использованы как общенаучные методы (анализ и синтез), так и специфические методы экономических исследований (анализ тенденций и причинно-следственных связей), а также представлены графические интерпретации. Автор приходит к выводу, что существует разнонаправленность движения взаимных прямых иностранных инвестиций, которая заключается в росте американских ПИИ в экономику Китая и в сокращении притока китайских прямых инвестиций в Соединенные Штаты Америки. Научно-практическая значимость работы состоит в возможности применения данного анализа для разработки методов решения проблемы по преодолению инвестиционных барьеров и привлечению прямых иностранных инвестиций в наиболее нуждающиеся отрасли экономики.

We compute the contribution of the additional fermions in Littles Higgs model in the framework of direct product groups where $[SU(2)\times U(1)]^2 $ gauge symmetry is embedded in SU(5) global symmetry and also in the framework of simple group where $SU(N)\times U(1)$ gauge symmetry breaks down to $SU(2)_L\times U(1)$. We calculate the contribution of the fermions to these couplings when $T$ parity is invoked. In addition, we re-examine the MSSM contribution at the chosen point of SPS1a' and compare with the SM and Little Higgs models.

description: В данной статье обсуждается одна из методик численного расчета элементов строительных конструкций переменной толщины с помощью метода наискорейшего спуска. В работе проведен поиск и систематизация имеющихся данных с последующей адаптацией к численному решению. Идея применения метода представлена на простом элементе конструкции – стержне, а именно балки с переменной по длине конструкции толщиной. Метод спуска применим для решения систем обыкновенных линейных дифференциальных уравнений, что позволяет описать поставленную задачу с достаточной инженерной точностью. После описания методики решения, представленный метод обобщается на более сложный элемент конструкции – пластинку переменной толщины. Результаты расчета методом спуска сопоставлялись с результатами численной реализации решения в среде Excel МКЭ расчета. Также в статье подчеркнуто, что прямые методы расчета, такие как метод Бубнова и метод Ритца, сильно отличаются от предложенного варианта численного расчета. В статье освещены наиболее важные преимущества метода наискорейшего спуска, а именно упрощение разрешающих уравнений, и отсутствие необходимости реализации дополнительного приближения начальных функций, так как структура реализуемых уравнений непостоянна и вариативна в реализации вариационных методов. В рамках научной статьи перед авторами ставились цели на изучение границ определения нового метода расчета конструкций переменной толщины и области их применения в инженерной деятельности.

description: We study the one-neutron removal strength of the 7He ground state, which provides us with the 6He-n component in 7He. The He isotopes are described on the basis of the 4He+Xn cluster model (X=1,2,3). The complex scaling method is applied to describe not only the Gamow resonances but also the nonresonant continuum states of valence neutrons, with the correct boundary condition of particle decays. The one-neutron removal strength of 7He into the unbound states of 6He is calculated using the complex-scaled Green's function, in which a complex-scaled complete set of 4He+n+n states is adopted. Using this framework, we investigate resonant and nonresonant contributions of the strength, which individually produce specific structures in the distributions. In addition, we propose a method to obtain the real-value strength using the complex values of spectroscopic factors of Gamow states. As a result, the 6He(2+) resonance is found to give the largest contribution.

Up Jacob's ladder: Andrew Johnson's rise to power, 1835-1857
Creators: name: Williams, Raymond Brinley
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study is to critically examine Andrew Johnson's early political career, from 1835 to 1857. Johnson remains today one of the most controversial figures in American history. His role as President during Reconstruction has initiated a century of debate over his character and behavior. In the process of this bitter controversy, few scholars have attempted to explain his personality and political behavior in terms of his early public life. This thesis will systematically investigate Johnson's career as a Tennessee representative and senator (1835-1843), United States Congressman (1843-1853), Governor of Tennessee (1853-1857). Through an intensive analysis of Johnson's letters and speeches, as well as contemporary accounts and newspaper sources, it will be established that throughout the period examined, Andrew Johnson behaved as a loyal Jacksonian Democrat and an ardent Southerner. In the process, the study will refute the modern historical interpretation which contends that Johnson was a political maverick and an abnormal personality. Through the use of recent social science methods such as roll-call analysis and attitude scaling, Johnson's voting pattern in Congress will be scrutinized and presented to determine political consistency and allegiances. Johnson's political progression from a minor border state politician to presidential aspirant will be discussed in terms of his participation in the slavery controversy, the debates over tariffs, internal improvements, land, and other divisive and national issues, to bring into focus his political behavior in relation to the behavior of his contemporaries. Andrew Johnson will emerge as an ambitious Southern Democrat, who followed his party, represented his people, and was loyal to his section, from the necessity of political expediency and from a sense of idealistic conviction. Although neither a contemner of the popular will nor a selfless consul of the people's interests, Johnson achieved reforms and benefits for the people that could only have been achieved as a result of his driving ambition. One fact will be obvious: he did not act as the paranoidal and masochistic apolitical fanatic that modern scholarship has pictured him.

description: The next generation of weak lensing surveys will trace the growth of large scale perturbations through a sequence of epochs, offering an opportunity to test General Relativity (GR) on cosmological scales. We review in detail the parametrization used in MGCAMB to describe the modified growth expected in alternative theories of gravity and generalized dark energy models. We highlight its advantages and examine several theoretical aspects. In particular, we show that the same set of equations can be consistently used on super-horizon and sub-horizon linear scales. We also emphasize the sensitivity of data to scale-dependent features in the growth pattern, and propose using Principal Component Analysis to converge on a practical set of parameters which is most likely to detect departures from GR. The connection with other parametrizations is also discussed.

description: Wind and solar energy’s rapid development has created a significant need for low-cost energy storage to enable renewables at grid level. To meet these challenges, metal-air batteries and fuel cells are being considered for base-load energy storage while high power applications like frequency regulation and uninterruptable power supplies (UPS) can be addressed using high energy pseudocapacitors. The major bottleneck to metal-air battery and fuel cell commercialization is the sluggish oxygen reactions at the positive electrode that are industrially catalyzed using expensive precious metal catalysts like Pt and IrO₂. Here, the aim is to replace precious metal-catalysts with low-cost LaNiO₃ perovskites and N-doped CNTs in alkaline conditions and study their synergistic interactions and composite stability. The work is continued by studying the anion-intercalation pseudocapacitance in a perovskite oxide library with composition La [subscript 1-x] Sr [subscript x] BO [subscript 3-δ] (B = Mn, Fe, Co; 0 ≤ x ≤ 1) and found that increasing oxygen vacancy content universally increases the pseudocapacitance while the B-site element controlled the redox potential. The most pseudocapacitive materials were then used to make the first all perovskite asymmetric pseudocapacitors with a maximum energy density of 31 Wh kg⁻¹. This work was followed by using the principles learned to further extent the redox voltage potential difference using LaNi [subscript 1-x] Fe [subscript x] O [subscript 3-δ] and brownmillerite-SrFeO [subscript 2.5] to make an asymmetric pseudocapacitor. Doing this, the redox discharge potential was pushed all the way to 1.1 V which is the highest asymmetric pseudocapacitor discharge peak potential reported to date.

description: Few years ago, Cho and Vilenkin have proposed that topological defects can arise in symmetry breaking models without having degenerate vacua. These types of defects are known as vacuumless defects. In the present work, the gravitational field of a vacuumless global string and global monopole have been investigated in the context of Lyra geometry. We find the metric of the vacuumless global string and global monopole in the weak field approximations. It has been shown that the vacuumless global string can have repulsive whereas global monopole exerts attractive gravitational effects on a test particle. It is dissimilar to the case studied in general relativity.

description: Single particle interference lies at the heart of quantum mechanics. The archetypal double-slit experiment has been repeated with electrons in vacuum up to the more massive $C_{60}$ molecules. Mesoscopic rings threaded by a magnetic flux provide the solid-state analogous. Intra-molecular interference has been recently discussed in molecular junctions. Here we propose to exploit interference to achieve all-electrical control of a single electron spin in quantum dots, a highly desirable property for spintronics and spin-qubit applications. The device consists of an interference single electron transistor (ISET), where destructive interference between orbitally degenerate electronic states produces current blocking at specific bias voltages. We show that in the presence of parallel polarized ferromagnetic leads the interplay between interference and the exchange coupling on the system generates an effective energy renormalization yielding different blocking biases for majority and minority spins. Hence, by tuning the bias voltage full control over the spin of the trapped electron is achieved.

description: The molecular gas composition in the inner 1 kpc disk of the starburst galaxy M82 resembles that of Galactic Photon Dominated Regions (PDRs). In particular, large abundances of the reactive ions HOC+ and CO+ have been measured in the nucleus of this galaxy. To investigate the origin of the large abundances of reactive ions in M82, we have completed our previous 30m HOC+ J=1-0 observations with the higher excitation HCO+ and HOC+ J=4-3 and 3-2 rotational lines. In addition, we have obtained with the IRAM Plateau de Bure Interferometer (PdBI) a 4" resolution map of the HOC+ 1-0 emission, the first ever obtained in a Galactic or extragalactic source. Our HOC+ interferometric image shows that the emission of the HOC+ 1-0 line is mainly restricted to the nuclear disk, with the maxima towards the E. and W. molecular peaks. In addition, line excitation calculations imply that the HOC+ emission arises in dense gas. Therefore, the HOC+ emission is arising in the dense PDRs embedded in the M82 nuclear disk, rather than in the intercloud phase and/or wind. We have improved our previous chemical model of M82 by (i) using the new version of the Meudon PDR code, (ii) updating the chemical network, and (iii) considering two different types of clouds (with different thickness). Most molecular observations (HCO+, HOC+, CO+, CN, HCN, H3O+) are well explained assuming that ~ 87 % of the mass of the molecular gas is forming small clouds (Av=5 mag) while only ~ 13 % of the mass is in large molecular clouds (Av=50 mag). Such small number of large molecular clouds suggests that M82 is an old starburst, where star formation has almost exhausted the molecular gas reservoir.

description: Let $Q$ be an acyclic quiver and $Λ$ be the complete preprojective algebra of $Q$ over an algebraically closed field $k$. To any element $w$ in the Coxeter group of $Q$, Buan, Iyama, Reiten and Scott have introduced and studied in \cite{Bua2} a finite dimensional algebra $Λ_w=Λ/I_w$. In this paper we look at filtrations of $Λ_w$ associated to any reduced expression $\mathbf{w}$ of $w$. We are especially interested in the case where the word $\mathbf{w}$ is $c$-sortable, where $c$ is a Coxeter element. In this situation, the consecutive quotients of this filtration can be related to tilting $kQ$-modules with finite torsionfree class.

Spin correlations near the surface of a three-dimensional Heisenberg antiferromagnet

description: Nearest-neighbor spin correlations are considered near the surface of a semi-infinite spin-$\frac12$ Heisenberg antiferromagnet on a simple cubic lattice. In the spin-wave approximation, the excitation spectrum of this model involves bulk modes -- standing spin waves and a quasi-two-dimensional mode of surface spin waves. These latter excitations eject the bulk excitations from the surface region thus dividing the antiferromagnet into two parts with different excitations. As a result absolute values of the spin correlations near the surface exceed the bulk value. In the surface region, the pattern of spin correlations resembles the comb structure recently obtained for the two-dimensional case.

description: In recent years, several families of hyperbolic knots have been shown to have both volume and $λ_1$ (first eigenvalue of the Laplacian) bounded in terms of the twist number of a diagram, while other families of knots have volume bounded by a generalized twist number. We show that for general knots, neither the twist number nor the generalized twist number of a diagram can provide two-sided bounds on either the volume or $λ_1$. We do so by studying the geometry of a family of hyperbolic knots that we call double coil knots, and finding two-sided bounds in terms of the knot diagrams on both the volume and on $λ_1$. We also extend a result of Lackenby to show that a collection of double coil knot complements forms an expanding family iff their volume is bounded.

description: Simulations of stochastically forced shear-flow turbulence in a shearing-periodic domain are used to study the spontaneous generation of large-scale flow patterns in the direction perpendicular to the plane of the shear. Based on an analysis of the resulting large-scale velocity correlations it is argued that the mechanism behind this phenomenon could be the mean-vorticity dynamo effect pioneered by Elperin, Kleeorin, and Rogachevskii in 2003 (Phys. Rev. E 68, 016311). This effect is based on the anisotropy of the eddy viscosity tensor. One of its components may be able to replenish cross-stream mean flows by acting upon the streamwise component of the mean flow. Shear, in turn, closes the loop by acting upon the cross-stream mean flow to produce stronger streamwise mean flows. The diagonal component of the eddy viscosity is found to be of the order of the rms turbulent velocity divided by the wavenumber of the energy-carrying eddies.
