Discovery of a localized excess in the millimeter emission of the protoplanetary disk around TW Hya
Creators: name: Tsukagoshi, Takashi
Publisher: name: Zenodo
Year: 2019

description: Planets are formed from dust and gas in circumstellar disks around young stars. Observations of dust and gas in circumstellar disks can provide fundamental information on planet formation processes, and high-resolution (sub-)millimeter imaging is now revealing the dust substructure likely generated by forming planets in disks. Here we report the detection of an excess in dust continuum emission at 233 GHz (1.3 mm in wavelength) in the circumstellar disk around TW Hya, the closest such system to Earth, revealed through deep 3 au resolution observations with the Atacama Large Millimeter/submillimeter Array (ALMA). We have carried out 3 au resolution continuum observations at 233 GHz (Band6) toward the protoplanetary disk (PPD) around TW Hya using ALMA in 2016 and 2017. The sensitivity has been improved by a factor of 3 than that of our previous cycle 3 observations. The overall structure is axisymmetric, and there are apparent gaps at 25 and 41 au as previously reported. The most remarkable new finding is a few au scale excess emission at the south-west part of the PPD. The excess emission is located at 52 au from the disk center and is 1.5 times brighter than the surrounding PPD. The extracted emission after subtracting the axisymmetric PPD emission has a size of 4.4x1.0 au and a total flux density of 250 micro-Jy, corresponding to a dust mass of 0.03 earth masses. Since the excess emission can also be marginally identified in the Band 7 image at almost the same position, the blob is unlikely a background source. The excess emission can be explained by a dust clump accumulated in a sm all elongated vortex or a massive circumplanetary disk around a Neptune mass forming-planet

description: We study double parton scattering (DPS) processes involving electroweak gauge bosons at the 13 TeV and 100 TeV proton-proton colliders. Specifically, we focus on three DPS channels: $W$-boson plus two jets ($W\otimes jj$), $Z$-boson plus two jets ($Z\otimes jj$), and same-sign $W$ pair production ($W^\pm\otimes W^\pm$). We demonstrate that the $Z\otimes jj$ process, which has not been paid too much attentions, is the best channel for measuring effective cross section $σ_{\rm eff}$. The accuracy of $σ_{\rm eff}$ measurement in the three DPS channels, especially the $W^\pm\otimes W^\pm$ production, is significantly improved at the 100 TeV colliders. We advocate that combined analysis of the three DPS channels could test the universality of effective cross section $σ_{\rm eff}$.

description: High temperature superconductivity has been found in many kinds of compounds built from planes of Cu and O, separated by spacer layers. Understanding why critical temperatures are so high has been the subject of numerous investigations and extensive controversy. To realize high temperature superconductivity, parent compounds are either hole-doped, such as {La$_{2}$CuO$_4$} (LCO) with Sr (LSCO), or electron doped, such as {Nd$_{2}$CuO$_4$} (NCO) with Ce (NCCO). In the electron doped cuprates, the antiferromagnetic phase is much more robust than the superconducting phase. However, it was recently found that the reduction of residual out-of-plane apical oxygens dramatically affects the phase diagram, driving those compounds to a superconducting phase. Here we use a recently developed first principles method to explore how displacement of the apical oxygen (A-O) in LCO affects the optical gap, spin and charge susceptibilities, and superconducting order parameter. By combining quasiparticle self-consistent GW (QS\emph{GW}) and dynamical mean field theory (DMFT), that LCO is a Mott insulator; but small displacements of the apical oxygens drive the compound to a metallic state through a localization/delocalization transition, with a concomitant maximum $d$-wave order parameter at the transition. We address the question whether NCO can be seen as the limit of LCO with large apical displacements, and elucidate the deep physical reasons why the behaviour of NCO is so different than the hole doped materials. We shed new light on the recent correlation observed between T$_c$ and the charge transfer gap, while also providing a guide towards the design of optimized high-Tc superconductors. Further our results suggest that strong correlation, enough to induce Mott gap, may not be a prerequisite for high-Tc superconductivity.

By taking the continuum limit, we obtain a "Hamiltonian formalism'' in which the geodesic distance plays the role of time. Applying this formalism, we obtain a universal function which describes the fractal structures of two dimensional quantum gravity in the continuum limit.

description: We have studied the longitudinal spin Seebeck effect in a polar antiferromagnet $α$-Cu$_{2}$V$_{2}$O$_{7}$ in contact with a Pt film. Below the antiferromagnetic transition temperature of $α$-Cu$_{2}$V$_{2}$O$_{7}$, spin Seebeck voltages whose magnetic field dependence is similar to that reported in antiferromagnetic MnF$_{2}$$\mid$Pt bilayers are observed. Though a small weak-ferromagnetic moment appears owing to the Dzyaloshinskii-Moriya interaction in $α$-Cu$_{2}$V$_{2}$O$_{7}$, the magnetic field dependence of spin Seebeck voltages is found to be irrelevant to the weak ferromagnetic moments. The dependences of the spin Seebeck voltages on magnetic fields and temperature are analyzed by a magnon spin current theory. The numerical calculation of spin Seebeck voltages using magnetic parameters of $α$-Cu$_{2}$V$_{2}$O$_{7}$ determined by previous neutron scattering studies reveals that the magnetic-field and temperature dependences of the spin Seebeck voltages for $α$-Cu$_{2}$V$_{2}$O$_{7}$$\mid$Pt are governed by the changes in magnon lifetimes with magnetic fields and temperature.

Comparison of the Two Followup Observation Strategies for Gravitational Microlensing Planet Searches
Creators: name: Han, Cheongho

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: There are two different strategies of followup observations for the detection of planets by using microlensing. One is detecting the light curve anomalies affected by the planetary caustic from continuous monitoring of all events detected by microlensing survey programs (type I strategy) and the other is detecting anomalies near the peak amplification affected by the central caustic from intensive monitoring of high amplification events (type II strategy). It was shown by Griest & Safizadeh that the type II strategy yields high planet detection efficiency per event. However, it is not known the planet detection rate by this strategy can make up a substantial fraction of the total rate. In this paper, we estimate the relative planet detection rates expected under the two followup observation strategies. From this estimation, we find that the rate under the type II strategy is substantial and will comprise $\sim 1/4$ -- 1/2 of the total rate. We also find that compared to the type I strategy the type II strategy is more efficient in detecting planets located outside of the lensing zone. We determine the optimal monitoring frequency of the type II strategy to be $\sim 20$ times/night, which can be easily achieved by the current microlensing followup programs even with a single telescope.

We show how these models can be twisted into a topological sector whose energy--momentum tensor is a BRST commutator. There is an infinite number of degrees of freedom associated to the zero modes of the solitons. As explicit realizations of such models we discuss the BRST quantization of a system of free fields, while in the interacting case we study $N=2$ complexified twisted Toda theories.

description: We investigate electrically-induced spin currents generated by the spin Hall effect in GaAs structures that distinguish edge effects from spin transport. Using Kerr rotation microscopy to image the spin polarization, we demonstrate that the observed spin accumulation is due to a transverse bulk electron spin current, which can drive spin polarization nearly 40 microns into a region in which there is minimal electric field. Using a model that incorporates the effects of spin drift, we determine the transverse spin drift velocity from the magnetic field dependence of the spin polarization.

description: The presence of dams has direct negative effects on populations of migrating fish and their riverine habitat as well as impacts on the ecosystem services they provide. Fishways, provide upstream and downstream passage that is safe and timely, comprising specifically of “physical structures, facilities, or devices necessary to maintain all life stages of such fish, and project operations and measures related to such structures, facilities, or devices which are necessary to ensure the effectiveness of such structures, facilities or devices for such fish” (National Energy Policy Act 1992). Fishways, sloped channels or elevators that connect the tailrace to the head of the dam, are one type of mitigation strategy; however there is a need for evaluating their effectiveness as populations of migrating fish continue to decline. This study is a two part investigation of the Auxiliary Water System (AWS), a pivotal technology in guiding fish into the fishway entrances. To effectively attract fish to the fishway, contributions from the AWS are essential; however, the hydraulic complexities associated with AWS inside the entrance channel may be causing negative behavioral responses to safe and timely fish passage. The content of the research presented in this paper is twofold. First it provides a review of the state of AWS in the field through a review of criteria manuals and the building of the Fishway Systems at Hydropower (FiSH) database. The database hosts predominantly fishways from the Northeast. The results indicate most AWS designs are gravity fed floor diffusers followed by gravity fed wall diffusers. Second, the study provides primary insight on the behavioral response of American shad to wall diffusers in the fishway entrance. During the spring of 2019, research was conducted on a full-scale wall diffuser using actively migrating American shad to evaluate the behavioral responses in a controlled flume environment. The experiment held constant flow conditions in the entrance channel immediately upstream of the diffuser. Flow through the AWS remained constant, while the diffuser velocity varied from 0.5 to 1.0 fps. Hydraulic data on the diffuser was gathered from a 1:8 scale physical model. The data analysis draws spatial and temporal correlations between the hydraulic parameters of the system, namely velocity, and the tracked fish movement through the study area. The data analysis from the behavioral and hydraulic experiments indicates better passage and preferable hydraulics for the 0.5 fps velocity treatment. The evaluation of this widely used technology further informs decisions regarding improvement and implementation of fishway technology.

The model consists of a non-linear excitonic oscillator coupled to a cavity mode which is driven by the external fields, and predicts the output power, below threshold gain and spectral blue shifts of the parametric oscillator. The predictions are found to be in excellent agreement with the experimental data.

description: We present a new method for replacing the outermost layers of stellar models with interpolated atmospheres based on results from 3D simulations, in order to correct for structural inadequacies of these layers. This replacement is known as patching. Tests, based on 3D atmospheres from three different codes and interior models with different input physics, are performed. Using solar models, we investigate how different patching criteria affect the eigenfrequencies. These criteria include the depth, at which the replacement is performed, the quantity, on which the replacement is based, and the mismatch in $T_\mathrm{eff}$ and $\log g$ between the un-patched model and patched 3D atmosphere. We find the eigenfrequencies to be unaltered by the patching depth deep within the adiabatic region, while changing the patching quantity or the employed atmosphere grid leads to frequency shifts that may exceed $1\,μ\mathrm{Hz}$. Likewise, the eigenfrequencies are sensitive to mismatches in $T_\mathrm{eff}$ or $\log g$. A thorough investigation of the accuracy of a new scheme, for interpolating mean 3D stratifications within the atmosphere grids, is furthermore performed. Throughout large parts of the atmosphere grids, our interpolation scheme yields sufficiently accurate results for the purpose of asteroseismology. We apply our procedure in asteroseismic analyses of four \textit{Kepler} stars and draw the same conclusions as in the solar case: Correcting for structural deficiencies lowers the eigenfrequencies, this correction is slightly sensitive to the patching criteria, and the remaining frequency discrepancy between models and observations is less frequency-dependent. Our work shows the applicability and relevance of patching in asteroseismology.

description: Puiden istuttaminen viljelykelpoiselle maalle tarkoittaa, että tämä ala on poissa vuotuisesta tuotannosta. Systeemin suunnittelusta riippuen tämä voi olla jopa 25% kasvatusalasta. Puista ei välttämättä saa hyötyä vielä moneen vuoteen istuttamisen jälkeen: tämä vaihtelee viidestä vuodesta (hedelmiä tekevät lajit ja lyhyen kierron pusikot) useaan kymmeneen vuoteen (puutavaraksi kasvatettavat lajit). Monissa agrometsätaloussysteemeissä puiden runkojen väliin ja latvusten alle jäävä alue jätetään huomaamatta ja hyödyntämättä, mikä voi hoitamattomana aiheuttaa ongelmia rikkaruohojen kanssa. Sen sijaan, että tämä alue nähtäisiin hukkaan menevänä tilana, se voi tarjota uusia mahdollisuuksia uusien viljelykasvien sijoittamiseen, lisäten näin tuotantoa ja monipuolistan tilan myytäviä tuotteita. - Installing trees in intraparcellar means using the area normally allocated to the main crop. Depending on the design of the system, this could represent up to 25% of the cultivated area. There may be no commercial production of trees for many years after planting; this ranges from about five years for fruit species or short-rotation coppice systems to several decades for timber species. In many agroforestry systems, the strip on the tree line is a neglected and underutilized area, which can create weed control problems. Rather than being considered wasted space, this band offers opportunities to introduce new crops, thus increasing production and diversifying the farm's marketable range of products.
Radio Halos of Galaxy Clusters from Hadronic Secondary Electron Injection in Realistic Magnetic Field Configurations

name: Ensslin, Torsten A.
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: We investigate the possibility that radio halos of clusters of galaxies are caused by synchrotron emission of cosmic ray electrons (CRe), which were produced by cosmic ray protons (CRp) interacting hadronically with the intra-cluster medium (ICM) protons. We perform cosmological magneto-hydrodynamics (MHD) simulations to obtain a sample of ten magnetized galaxy clusters. They provide realistic models of the gas and magnetic field distribution, needed to predict the CRe production rates, their cooling, and their synchrotron emissivity. We assume a CRp population within the ICM with an energy density which has a constant ratio to thermal energy density. This ratio is adjusted in such a way that one of the simulated clusters reproduces the radio luminosity of the radio halo of the Coma cluster of galaxies. Our model exhibits the observed low degree of radio polarization and has a similar radial emission profile as the Coma cluster. We provide estimates for the expected gamma ray and neutrino flux. The necessary CRp/thermal energy ratio is 4 ... 14% ${(E_{p,min}/GeV)}^{-0.375}$ (for the range of magnetic field strengths suggested by Faraday measurements), where $E_{p,min}$ is the lower kinetic energy cutoff of the CRp with spectral index $α_p \approx 2.375$. Assuming this ratio to be the same in the whole set of simulated clusters a $T_x-L_ν$ relation is predicted which follows the observed relation well.

Non-equilibrium ionization by a periodic electron beam II. Synthetic Si IV and O IV transition region spectra
Creators: name: Dzifcakova, Elena
name: Dudik, Jaroslav
Publisher: name: arXiv
Year: 2017
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Transition region (TR) spectra typically show the Si IV 1402.8 A line to be enhanced by a factor of 5 or more compared to the neighboring O IV 1401.2 A, contrary to predictions of ionization equilibrium models and the Maxwellian distribution of particle energies. Non-equilibrium effects in TR spectra are therefore expected. To investigate the combination of non-equilibrium ionization and high-energy particles, we apply the model of the periodic electron beam, represented by a kappa-distribution that recurs at periods of several seconds, to plasma at chromospheric temperatures of 10^4 K. This simple model can approximate a burst of energy release involving accelerated particles. Instantaneous time-dependent charge states of silicon and oxygen were calculated and used to synthesize the instantaneous and period-averaged spectra of Si IV and O IV. The electron beam drives the plasma out of equilibrium. At electron densities of N_e = 10^10 cm^-3, the plasma is out of ionization equilibrium at all times in all cases we considered, while for a higher density of N_e = 10^11 cm^-3, ionization equilibrium can be reached toward the end of each period, depending on the conditions. In turn, the character of the period-averaged synthetic spectra also depends on the properties of the beam. While the case of kappa = 2 results in spectra with strong or even dominant O IV, higher values of kappa can approximate a range of observed TR spectra. Spectra similar to typically observed spectra, with the Si IV 1402.8 A line about a factor 5 higher than O IV 1401.2 A, are obtained for kappa = 3. An even higher value of kappa = 5 results in spectra that are exclusively dominated by Si IV, with negligible O IV emission. This is a possible interpretation of the TR spectra of UV bursts, although an interpretation that requires a density that is 1-3 orders of magnitude lower than for equilibrium estimates.

ALMA Deep Field in the SSA22 proto-cluster at z=3
Creators: name: Umehata, Hideki
Publisher: name: Zenodo
Year: 2019

description: Galaxies and nuclei in the dense environment at high redshift provide a good laboratory to investigate the accelerated, most extreme evolution of galaxies at a given epoch. The SSA22 proto-cluster at z=3.1 has known to have a 50 (comoving) Mpc-scale cosmic structure, which makes the field a suitable target in this regards. To identify dust-obscured star-formation, a contiguous 20 arcmin^2 regions at the node were observed by ALMA band 6. About 7 arcmin^2 region has 1sigma sensitivity of 25uJy/beam at 1.2mm, while the remaining ~13 region has 1sigma 60 uJy/beam at 1.1mm. In total 57 ALMA sources have been identified above 5sigma, which makes the field one of the richest field of ALMA-identified submillimeter galaxies. The follow-up spectroscopy confirmed about 20 sources as exact proto-cluster members so far. Together with high X-ray AGN fraction, our results suggest that the vigorous star formation activity and the growth of super massive black holes (SMBHs) occurred simul taneously in the densest regions at z~3. Abundant gas fueling from cosmic web is suggested from co-spatial, deep mosaic observations of ALMA band 3 (for CO(3-2)) and MUSE survey (for Lyman-alpha). We argue that we are seeing the most active historical phase of the massive galaxy population found in the core of the clusters in the present-day universe.

description: A semiclassical theory of single and multi-mode lasing is derived for open complex or random media using a self-consistent linear response formulation. Unlike standard approaches which use closed cavity solutions to describe the lasing modes, we introduce an appropriate discrete basis of functions which describe also the intensity and angular emission pattern outside the cavity. This constant flux (CF) basis is dictated by the Green function which arises when formulating the steady state Maxwell-Bloch equations as a self-consistent linear response problem. This basis is similar to the quasi-bound state basis which is familiar in resonator theory and it obeys biorthogonality relations with a set of dual functions. Within a single-pole approximation for the Green function the lasing modes are proportional to these CF states and their intensities and lasing frequencies are determined by a set of non-linear equations. When a near threshold approximation is made to these equations a generalized version of the Haken-Sauermann equations for multi-mode lasing is obtained, appropriate for open cavities. Illustrative results from these equations are given for single and few mode lasing states, for the case of dielectric cavity lasers. The standard near threshold approximation is found to be unreliable. Applications to wave-chaotic cavities and random lasers are discussed.

Cold War Searches for Intelligence
Creators: name: Charbonneau, Rebecca
Publisher: name: Zenodo

description: This talk will examine how CETI developed out of the Cold War, ultimately arguing that CETI is a particularly valuable discipline through which to analyze many of the major characteristics of Cold War science and geopolitics because its infrastructure, instruments, and ideologies reveal the dualities and contradictions of the era by promoting communication and internationalism while simultaneously depending on the military and imperialism. Understanding the Cold War origins of CETI is critical for analyzing contemporary searches for extraterrestrial intelligence, as it gives insight into how existing structures and theories came to exist, and how they are still in many ways subject to political and ideological influences.

Year: 1993
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A new way of solving the descent equations corresponding to the Wess-Zumino consistency conditions is presented. The method relies on the introduction of an operator $δ$ which allows to decompose the exterior space-time derivative $d$ as a $BRS$ commutator. The case of the Yang-Mills theories is treated in detail.

description: To investigate the origin of the features discovered in the exoplanet population, the knowledge of exoplanets' mass and radius with a good precision is essential. In this paper, we report the discovery of three transiting exoplanets by the SuperWASP survey and the SOPHIE spectrograph with mass and radius determined with a precision better than 15 %. WASP-151b and WASP-153b are two hot Saturns with masses, radii, densities and equilibrium temperatures of 0.31^{+0.04}_{-0.03} MJ, 1.13^{+0.03}_{-0.03} RJ, 0.22^{-0.03}_{-0.02} rhoJ and 1, 290^{+20}_{-10} K, and 0.39^{+0.02}_{-0.02} MJ, 1.55^{+0.10}_{-0.08} RJ, 0.11^{+0.02}_{-0.02} rhoJ and 1, 700^{+40}_{-40} K, respectively. Their host stars are early G type stars (with magV ~ 13) and their orbital periods are 4.53 and 3.33 days, respectively. WASP-156b is a Super-Neptune orbiting a K type star (magV = 11.6) . It has a mass of 0.128^{+0.010}_{-0.009} MJ, a radius of 0.51^{+0.02}_{-0.02} RJ, a density of 1.0^{+0.1}_{-0.1} rhoJ, an equilibrium temperature of 970^{+30}_{-20} K and an orbital period of 3.83 days. WASP-151b is slightly inflated, while WASP-153b presents a significant radius anomaly. WASP-156b, being one of the few well characterised Super-Neptunes, will help to constrain the formation of Neptune size planets and the transition between gas and ice giants. The estimates of the age of these three stars confirms the tendency for some stars to have gyrochronological ages significantly lower than their isochronal ages. We propose that high eccentricity migration could partially explain this behaviour for stars hosting a short period planet. Finally, these three planets also lie close to (WASP-151b and WASP-153b) or below (WASP-156b) the upper boundary of the Neptunian desert. Their characteristics support that the ultra-violet irradiation plays an important role in this depletion of planets observed in the exoplanet population.

description: Magnetic metamaterials composed of split-ring resonators or $U-$type elements may exhibit discreteness effects in THz and optical frequencies due to weak coupling. We consider a model one-dimensional metamaterial formed by a discrete array of nonlinear split-ring resonators with each ring interacting with its nearest neighbours. On-site nonlinearity and weak coupling among the individual array elements result in the appearence of discrete breather excitations or intrinsic localized modes, both in the energy-conserved and the dissipative system. We analyze discrete single and multibreather excitations, as well as a special breather configuration forming a magnetization domain wall and investigate their mobility and the magnetic properties their presence induces in the system.

description: Standard as well as irradiated silicon pixel detectors developed for the ATLAS experiment were tested in a beam. Digital and analog resolutions were determined comparing the positions measured by a microstrip telescope and by the pixel detector. Digital resolutions of 10 um and analog resolutions of 6 um (before irradiation) and 10 um (after irradiation) are obtained without subtracting the error on the position determined by the telescope.

description: Using the Mid-Infrared Spectrometer on board the Infrared Telescope in Space and the low-resolution grating spectrometer (PHT-S) on board the Infrared Space Observatory, we obtained 820 mid-infrared (5 to 12 $μ$m) spectra of the diffuse interstellar medium (DIM) in the Galactic center, W51, and Carina Nebula regions. These spectra indicate that the emission is dominated by the unidentified infrared (UIR) emission bands at 6.2, 7.7, 8.6, and 11.2 $μ$m. The relative band intensities (6.2/7.7 $μ$m, 8.6/7.7 $μ$m, and 11.2/7.7 $μ$m) were derived from these spectra, and no systematic variation in these ratios was found in our observed regions, in spite of the fact that the incident radiation intensity differs by a factor of 1500. Comparing our results with the polycyclic aromatic hydrocarbons (PAHs) model for the UIR band carriers, PAHs in the DIM have no systematic variation in their size distribution, their degree of dehydrogenation is independent of the strength of UV radiation field, and they are mostly ionized. The latter finding is incompatible with past theoretical studies, in which a large fraction of neutral PAHs is predicted in this kind of environment. A plausible resolution of this discrepancy is that the recombination coefficients for electron and large PAH positive ion are by at least an order of magnitude less than those adopted in past theoretical studies. Because of the very low population of neutral state molecules, photoelectric emission from interstellar PAHs is probably not the dominant source of heating of the diffuse interstellar gas. The present results imply constant physical and chemical properties of the carriers of the UIR emission bands in the DIM.

description: Each state in the USA exhibited a unique response to the COVID-19 outbreak, along with variable levels of testing, leading to different actual case burdens in the country. In this study, via per capita testing dependent ascertainment rates, along with case and death data, we fit a minimal epidemic model for each state. We estimate infection-level responsive lockdown/self-quarantine entry and exit rates (representing government and behavioural reaction), along with the true number of cases as of 31 May 2020. Ultimately, we provide error-corrected estimates for commonly used metrics such as infection fatality ratio and overall case ascertainment for all 55 states and territories considered, along with the USA in aggregate, in order to correlate outbreak severity with first wave intervention attributes and suggest potential management strategies for future outbreaks. We observe a theoretically predicted inverse proportionality relation between outbreak size and lockdown rate, with scale dependent on the underlying reproduction number and simulations suggesting a critical population quarantine ‘half-life’ of 30 days independent of other model parameters.

Anomalous scaling in homogeneous isotropic turbulence

Year: 2000
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The anomalous scaling exponents $ζ_{n}$ of the longitudinal structure functions $S_{n}$ for homogeneous isotropic turbulence are derived from the Navier-Stokes equations by using field theoretic methods to develop a low energy approximation in which the Kolmogorov theory is shown to act effectively as a mean field theory. The corrections to the Kolmogorov exponents are expressed in terms of the anomalous dimensions of the composite operators which occur in the definition of $S_{n}$. These are calculated from the anomalous scaling of the appropriate class of nonlinear Green's function, using an $uv$ fixed point of the renormalisation group, which thereby establishes the connection with the dynamics of the turbulence. The main result is an algebraic expression for $ζ_{n}$, which contains no adjustable constants. It is valid at orders $n$ below $% g_{\ast}^{-1}$, where $g_{\ast}$ is the fixed point coupling constant. This expression is used to calculate $ζ_{n}$ for orders in the range $% n=2$ to 10, and the results are shown to be in good agreement with experimental data, key examples being $ζ_{2}=0.7$, $ζ_{3}=1$ and $% ζ_{6}=1.8$.
