description: Purpose: The purpose of this study was to evaluate the internal consistency and construct validity of the Traumatic Brain Injury Quality of Life Communication Item Bank (TBI-QOL COM) short form as a parent-proxy report measure. The TBI-QOL COM is a patient-reported outcome measure of functional communication originally developed as a self-report measure for adults with traumatic brain injury (TBI), but it may also be valid as a parent-proxy report measure for children who have sustained TBI.Method: One hundred twenty-nine parent-proxy raters completed the TBI-QOL COM short form 6 months postinjury as a secondary aim of a multisite study of pediatric TBI outcomes. The respondents’ children with TBI were between 8 and 18 years old (Mage = 13.2 years old) at the time of injury, and the proportion of TBI severity mirrored national trends (73% complicated–mild; 27% moderate or severe).Results: The parent-proxy report version of the TBI-QOL COM displayed strong internal consistency (ordinal α = .93). It also displayed evidence of known-groups validity by virtue of more severe injuries associated with more abnormal scores. The instrument also showed evidence of convergent and discriminant validity by displaying a pattern of correlations with other constructs according to their conceptual relatedness to functional communication.Conclusions: This preliminary psychometric investigation of the TBI-QOL COM supports the further development of a parent report version of the instrument. Future development of the TBI-QOL COM with this population may include expanding the content of the item bank and developing calibrations specifically for parent-proxy raters.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Control of arthropod-borne infectious diseases – extrapolating from the known to the unknown
Creators: name: Taylor-Robinson, Andrew
Publisher: name: F1000 Research Limited
Year: 2019

description: Mosquito-transmitted infectious diseases have a significant impact on human health: malaria, dengue and yellow fever exact a huge toll of morbidity and mortality annually on a global scale. Lessons may be learnt from our experiences with these major parasite and viral pathogens in regard to understanding the diagnosis, treatment, control and prevention of (re)-emerging infectious diseases. This applies to aetiological agents such as Zika, which has caused a recent notable epidemic, but also less well characterized arthropod-borne viral infections, of which there are at least 70 identified in Australia alone, the putative cause of many cases of fevers of unknown origin. Given the apparently increasing rate of changes in climate, human movement and vector distribution, these neglected diseases should be researched further so that in the event of conditions becoming conducive to a sustained outbreak that poses a threat to public health suitable emergency control measures may be efficiently enforced.

description: This is a description of HBV viral loads in a UK cohort of chronic HBV infection. We demonstrated that HBV has a low median HBV viral load of 3.4 log10 IU/mL, lower than that of either HIV or HCV, and a bimodal distribution with peaks in viral load at around 3 log10 IU/mL and 8 log10 IU/mL. We also showed significant differences in HBV viral load between ethnicities and dependent on HBeAg status.

We summarise that a better understanding of HBV viral loads within populations can aid understanding of the different disease phenotypes, risk factors for development of liver cirrhosis and hepatocellular carcinoma and ultimately help stratify patient treatment.

description: We describe a general method of obtaining the constraints between area variables in one approach to area Regge calculus, and illustrate it with a simple example. The simplicial complex is the simplest tessellation of the 4-sphere. The number of independent constraints on the variations of the triangle areas is shown to equal the difference between the numbers of triangles and edges, and a general method of choosing independent constraints is described. The constraints chosen by using our method are shown to imply the Regge equations of motion in our example.

description: ABSTRACT Purpose: The paper examines the potential effects of academic publications on patenting and the share of high technology exports. We test the short-run and the long-run causalities among high technology exports, the number of academic publications and the number of patents in three separate models. Methodology/Approach: Our sample consists of panel data for 61 countries and 20 years. The panel Granger causality and vector error correction model have been used in order to capture the short-run causalities. Furthermore, panel cointegration regressions have been applied to test for long-run causalities. Findings: Our results strongly suggest that there is a positive long-run effect of academic publications on both patenting and the share of high technology exports. This suggests that the outcomes of basic science in the form publications strongly support technological development, and thus emphasises the importance of basic research. In addition the effect of patents on high technology exports is mostly insignificant when controlling for academic publications and GDP. Research Limitation/implication: First, the variables used in the analysis are only proxies. The scope of the data has been significantly limited by the data availability. This leads also to limited the number of control variables. Originality/Value of paper: There are still only a very limited number of studies testing the effect of academic outcomes on the technological development of the economy. Our research brings new empirical insights into this problem.
Observing the Berry phase in diffusive conductors: Necessary conditions for adiabaticity

description: In a recent preprint (cond-mat/9803170), van~Langen, Knops, Paasschens and Beenakker attempt to re-analyze the proposal of Loss, Schoeller and Goldbart (LSG) [Phys. Rev. B~48, 15218 (1993)] concerning Berry phase effects in the magnetoconductance of diffusive systems. Van Langen et al. claim that the adiabatic approximation for the Cooperon previously derived by LSG is not valid in the adiabatic regime identified by LSG. It is shown that the claim of van~Langen et al. is not correct, and that, on the contrary, the magnetoconductance does exhibit the Berry phase effect within the LSG regime of adiabaticity. The conclusion reached by van~Langen et al. is based on a misinterpretation of field-induced dephasing effects, which can mask the Berry phase (and any other phase coherent phenomena) for certain parameter values.

The usage of electrical notions in the beginning makes the consideration understandable for every physicists. Perhaps it is the simplest derivation of these well-known theorems in statistical physics. The classical limit is understandable as a consequence of Waterston-Herapath equipartition theorem.

description: Using Monte Carlo simulations (MCS) and the Migdal-Kadanoff approximation (MKA), Marinari et al. study in their comment on our paper the link overlap between two replicas of a three-dimensional Ising spin glass in the presence of a coupling between the replicas. They claim that the results of the MCS indicate replica symmetry breaking (RSB), while those of the MKA are trivial, and that moderate size lattices display the true low temperature behavior. Here we show that these claims are incorrect, and that the results of MCS and MKA both can be explained within the droplet picture.

The particular $2$-functionals, which are particularly relevant in quantum physics, are explicitly given in terms of the degrees and the characteristic parameters of the polynomials. They include the well-known power moments and the novel Krein-like moments. Moreover, various related types of exponential and logarithmic functionals are also investigated.

description: We study dynamics of a probe molecule, driven by an external constant force in a liquid monolayer on top of solid surface. In terms of a microscopic, mean-field-type approach, we calculate the terminal velocity of the probe molecule. This allows us to establish the analog of the Stokes formula, in which the friction coefficient is interpreted in terms of the microscopic parameters characterizing the system. We also determine the distribution of the monolayer particles as seen from the stationary moving probe molecule and estimate the self-diffusion coefficient for diffusion in a liquid monolayer.

description: All-dielectric nanoantennas are a promising alternative to plasmonic optical antennas for engineering light emission because of their low-loss nature in the optical spectrum. Nevertheless, it is still challenging to manipulate directional light emission with subwavelength all-dielectric nanoantennas. Here, we propose and numerically demonstrate that a hollow silicon nanodisk can serve as a versatile antenna for directing and enhancing the emission from either an electric or magnetic dipole emitter. When primarily coupled to both electric and magnetic dipole modes of a nanoantenna, broadband nearly-unidirectional emission can be realized by the interference of two modes, which can be spectrally tuned via the geometric parameters in an easy way. More importantly, the emission directions for the magnetic and electric dipole emitters are shown as opposite to each other through control of the phase difference between the induced magnetic and electric dipole modes of the antenna. Meanwhile, the Purcell factors can be enhanced by more than one order of magnitude and high quantum efficiencies can be maintained at the visible spectrum for both kinds of dipole emitters. We further show that these unidirectional emission phenomena can withstand small disorder effects of in-plane dipole orientation and location. Our study provides a simple yet versatile platform that can shape the emission of both magnetic and electric dipole emitters.

description: Transports preserving the angle between two contravariant vector fields but changing their lengths proportional to their own lengths are introduced as ''conformal'' transports and investigated over spaces with contravariant and covariant affine connections (whose components differ not only by sign) and metrics. They are more general than the Fermi-Walker transports. In an analogous way as in the case of Fermi-Walker transports a conformal covariant differential operator and its conformal derivative are defined and considered over the above mentioned spaces. Different special types of conformal transports are determined inducing also Fermi-Walker transports for orthogonal vector fields as special cases. Conditions under which the length of a non-null contravariant vector field could swing as a homogeneous harmonic oscillator are established. The results obtained regardless of any concrete field (gravitational) theory could have direct applications in such types of theories. PACS numbers: 04.90.+e; 04.50.+h; 12.10.Gq; 02.40.Vh

Reliable, low-cost datalogging alternatives promote transfer of knowledge and technology to the wider geotechnical and geoscientist community. Alternative systems can ease increased data resolution on large projects, operate in remote locations with restricted site access, or allow developing countries access to reliable and cost-effective datalogging solutions. A low-cost prototype datalogger was developed and tested in the laboratory with the use of open-source materials. Open-source example code is provided at the permanent links included in this paper. The materials for the prototype were 20 % the cost of commercial datalogging units with similar capabilities. With labor, these custom-built units were 35–45 % the cost of a purchased datalogger. Measurements from commercial units and the prototype datalogger were compared to determine the prototype’s accuracy. The datalogger was deployed in place of commercially available dataloggers at three sites across western Canada in the past two years. Laboratory and field testing of the low-cost datalogger has shown the prototype to be easily adaptable to various sensor types. The study experimented with negative pore water pressure (matric suction), volumetric water content, and temperatures from SDI-12 sensors as well as positive pore water pressure and temperature from vibrating wire piezometers. Telemetry modules have been attached to remote dataloggers, transmitting occasional data points, and periodically verifying system operation. Assembly, installation, and monitoring with the low-cost datalogging system over the past two years has demonstrated their durability in field applications. The implementation of a low-cost, open-source geotechnical datalogging system can be a challenge in some locations and requires the consideration of limitations, which are addressed.
Lattice Distortion Mediated Paramagnetic Relaxation in High-Spin High-Symmetry Molecular Magnets
Creators: name: Garg, Anupam

Year: 1998
Subjects: subject: Condensed Matter (cond-mat)

description: Field-dependent maxima in the relaxation rate of the magnetic molecules Mn_12-Ac and Fe_8-tacn have commonly been ascribed to some resonant tunneling phenomenon. We argue instead that the relaxation can be understood as purely due to phonons. The rate maxima arise because of a Jahn-Teller-like distortion caused by the coupling of lattice phonons to degenerate Zeeman levels of the molecule at the top of the barrier. The binding energy of the distorted intermediate states lowers the barrier height and increases the relaxation rate. A nonperturbative calculation of this effect is carried out for a model system. An approximate result for the field variation near a maximum is found to agree reasonably with experiment.

description: We present a HST study of the metal-rich globular cluster NGC6553 using WFPC2, NICMOS and STIS. Our primary motivation is to calibrate the STIS broad-band LP magnitude against $V_{555}$ and $I_{814}$ magnitudes for stars of known metallicity and absolute (visual) magnitude, for application to our study of LMC globular clusters. NGC6553 has been shown in earlier studies to have a very unusual colour-magnitude diagram, so we also use our data to investigate the reddening, distance, luminosity function and structure of this cluster. We deduce a higher metallicity and smaller distance modulus than did some previous studies, but emphasise that very large patchy extinction on small angular scales prohibits accurate determination of the parameters of this cluster. The horizontal branch of NGC6553 in ($V,V-I$) is tilted at an angle close to that of the reddening vector. We show that extinction does not, however, explain the tilt, which is presumably a metallicity effect. The colour-magnitude diagram shows an apparent second turnoff some 1.5 magnitudes fainter than that of the cluster. We show that this is most likely the background Galactic bulge: however, in that case, the colour-magnitude diagram of NGC6553 is not a good match to that of the field bulge population. The cluster is probably more metal-rich than is the mean field bulge star.

I was pleasantly surprised when I heard that one of my long-forgotten manuscripts about the Emirates was accidentally discovered in the midst of a pile of photographs recently donated to the National Center for Documentation & Research by Lady Hawley, wife of Sir Donald Hawley, Political Agent at Dubai from 1958 to 1961.I am thankful to Lady Hawley for carefully preserving the write-up for nearly two decades and handing it over to NCDR - the archival repository of the UAE. As far as I can recall, I must have written it for Donald in the 1990s when I was stilldoing frontier work for the Emirates Ministry of the Interior. This work was initiated by late Shaikh Zayed Bin Sultan Al Nahyan when he asked me back to the UAE to work on the frontiers. This late frontier work of mine concluded in 1996 when I spent a long time working with Col. (later Brigadier) Salem al Mazroui of the Special Security Forces on the Ras Al Khaimah-Fujairah frontier. I gave a copy of the paper to Donald to help clarify for him my knowledge of the background of the oral history of the Emirates. - from the introduction

description: We investigate the spin and pseudospin symmetry in the single-particle resonant states by solving the Dirac equation containing a Woods-Saxon potential with Green's function method. Taking double-magic nucleus $^{208}$Pb as an example, three spin doublets $3d$, $2h$, and $1j$ and three pseudospin doublets $3\tilde{p}$, $1\tilde{i}$, and $1\tilde{j}$ are obtained for the single-neutron resonant states. By analyzing the energy splittings, we find that the threshold effect plays an important role in resonant pseudospin doubles. Besides, there is a reversed level structure of pseudospin doublets in the continuum. Differently, all the width splittings of either the spin doublets or the pseudospin doublets are systematically positive and the splittings are very small except $1\tilde{j}$ doublet. Further studies show that the splittings of the energies and widths for the resonant (pseudo)spin doublets are independent. Besides, the similarity properties of the wave functions of the spin and pseudospin doublets still maintain well in resonant states.

description: Neutron scattering has been used to study the magnetic order and spin dynamics of the colossal magnetoresistive pyrochlore Tl_2Mn_2O_7. On cooling from the paramagnetic state, magnetic correlations develop and appear to diverge at T_C (123 K). In the ferromagnetic phase well defined spin waves are observed, with a gapless ($Δ<0.04$ meV) dispersion relation E=Dq^{2} as expected for an ideal isotropic ferromagnet. As T approaches T_C from low T, the spin waves renormalize, but no significant central diffusive component to the fluctuation spectrum is observed in stark contrast to the La$_{1-x}$(Ca,Ba,Sr)$_x$MnO$_3$ system. These results argue strongly that the mechanism responsible for the magnetoresistive effect has a different origin in these two classes of materials.

description: ABSTRACT Purpose: The paper examines the potential effects of academic publications on patenting and the share of high technology exports. We test the short-run and the long-run causalities among high technology exports, the number of academic publications and the number of patents in three separate models. Methodology/Approach: Our sample consists of panel data for 61 countries and 20 years. The panel Granger causality and vector error correction model have been used in order to capture the short-run causalities. Furthermore, panel cointegration regressions have been applied to test for long-run causalities. Findings: Our results strongly suggest that there is a positive long-run effect of academic publications on both patenting and the share of high technology exports. This suggests that the outcomes of basic science in the form publications strongly support technological development, and thus emphasises the importance of basic research. In addition the effect of patents on high technology exports is mostly insignificant when controlling for academic publications and GDP. Research Limitation/implication: First, the variables used in the analysis are only proxies. The scope of the data has been significantly limited by the data availability. This leads also to limited the number of control variables. Originality/Value of paper: There are still only a very limited number of studies testing the effect of academic outcomes on the technological development of the economy. Our research brings new empirical insights into this problem.

description: We present a detailed calculation of the magnetic couplings between nearest-neighbor and next-nearest-neighbor coppers in the edge-sharing geometry, ubiquitous in many cuprates. In this geometry, the interaction between nearest neighbor coppers is mediated via two oxygens, and the Cu-O-Cu angle is close to 90 degrees. The derivation is based on a perturbation expansion of a general Hubbard Hamiltonian, and produces numerical estimates for the various magnetic energies. In particular we find the dependence of the anisotropy energies on the angular deviation away from the 90 degrees geometry of the Cu-O-Cu bonds. Our results are required for the correct analysis of the magnetic structure of various chain, ladder and lamellar cuprates.

description: Η παρούσα μελέτη συνίσταται σε ακουστικές μετρήσεις του χρόνου αντήχησης και θορύβου βάθους σε έξι (6) αίθουσες του Ε.Μ.Π., οι οποίες έχουν ως κοινό χαρακτηριστικό τον τεράστιο όγκο, δηλαδή από 3.000 μέχρι 23.000 και το γεγονός ότι και οι έξι αίθουσες χρησιμοποιούνται ως εργαστηριακοί χώροι. Οι μετρήσεις έδειξαν ότι επικρατούν εξαιρετικά υψηλοί χρόνοι αντήχησης, οι οποίοι στη συνέχεια υποδεικνύεται πως θα μειωθούν για να επιτευχθεί ηχητική άνεση μέσα στο χώρο. Στις προτάσεις περιλαμβάνεται κατά βάση η εισαγωγή εκτενούς απορρόφησης με τη μορφή πρώτον, αναρτημένων τρισδιάστατων ηχοαπορροφητικών στοιχείων και δεύτερον, με τη μορφή επένδυσης και πλευρικών παρειών της αίθουσας. Η διορθωτική επέμβαση αναμένεται να βελτιώσει αποτελεσματικά τις συνθήκες ακρόασης ομιλίας μέσα στην αίθουσα (π.χ. άτυπη διεξαγωγή διάλεξης), καθώς και να μειώσει τη στάθμη των θορύβων που παράγονται μέσα στην αίθουσα.

description: Saccharomyces cerevisiae target of rapamycin (TOR) complex 2 (TORC2) is an essential regulator of plasma membrane lipid and protein homeostasis. How TORC2 activity is modulated in response to changes in the status of the cell envelope is unclear. Here we document that TORC2 subunit Avo2 is a direct target of Slt2, the mitogen-activated protein kinase (MAPK) of the cell wall integrity pathway. Activation of Slt2 by overexpression of a constitutively active allele of an upstream Slt2 activator (Pkc1) or by auxin-induced degradation of a negative Slt2 regulator (Sln1) caused hyperphosphorylation of Avo2 at its MAPK phosphoacceptor sites in a Slt2-dependent manner and diminished TORC2-mediated phosphorylation of its major downstream effector, protein kinase Ypk1. Deletion of Avo2 or expression of a phosphomimetic Avo2 allele rendered cells sensitive to two stresses (myriocin treatment and elevated exogenous acetic acid) that the cell requires Ypk1 activation by TORC2 to survive. Thus, Avo2 is necessary for optimal TORC2 activity, and Slt2-mediated phosphorylation of Avo2 down-regulates TORC2 signaling. Compared with wild-type Avo2, phosphomimetic Avo2 shows significant displacement from the plasma membrane, suggesting that Slt2 inhibits TORC2 by promoting Avo2 dissociation. Our findings are the first demonstration that TORC2 function is regulated by MAPK-mediated phosphorylation.

description: We consider a wave packet of a spin-1/2 particle in a gravitational field, the effect of which can be described in terms of a succession of local inertial frames. It is shown that integrating out of the momentum yields a spin mixed state, with the entropy dependent on the deviation of metric from the flat spacetime. The decoherence occurs even if the particle is static in the gravitational field.

description: Study of performance of water treatment plant (WTP) is essential to be assessed with all aspects and considerations including physical, chemical and bacteriological so as to determine its efficiency and to produce quality water to the consumer. Performance of any WTP is a crucial parameter to be evaluated to understand its operation, working, and efficiency. The present study aimed to evaluate the performance of Ifraz 2 WTP units, and to discover the problems of the efficiency in the units with providing appropriate solutions. Water samples were collected for six months from raw water, after clarification, after filtration, and storage tank. Turbidity removal efficiency for each unit and the whole WTP were calculated and presented. Results revealed that there is a wide variation of the raw water turbidity values which ranged from 51.8 NTU to 1978 NTU. Average removal efficiencies for the sedimentation unit, filtration unit, and the entire Ifraz 2 WTP were 92.25%, 64.99% and 97.54%, respectively. The efficiency of coagulation and flocculation processes are fluctuated due to the absence of optimum dosage of coagulant. In the filtration process, due to the little depth of filter bed, this makes the filtration process in low quality. For improving the process of filtration, an adequate adding of filter media is very necessary to improve filter efficiency. After disinfection and storage, the turbidity values of the treated water were increased in half of the samples due to availability of solids in the storage tank. A great part of solids removed after coagulation-flocculation and sedimentation tanks.
Anisotropic Strong Coupling Calculation of the Local Electromagnetic Response of High-Tc Superconductors

description: The electromagnetic response of the CuO2-planes is calculated within a strong coupling theory using model tight binding bands and momentum dependent pairing interactions representing spin fluctuations and phonon exchange. The superconducting state resulting from these interactions has d-wave symmetry. With phonon exchange included the order parameter amplitude grows rapidly below Tc at elevated frequencies which leads to improved agreement with the observed temperature dependence of the penetration depth. Good agreement between theory and experiment can only be achieved if it is assumed that the strength of the quasiparticle interaction decreases with temperature in the superconducting state. The amount of this reduction depends sensitively on the momentum dependence of the interactions, the energy dispersion and the position of the Fermi line.

description: Model input used for 10.5194/hess-2019-151 Abstract The Nile Delta is an important agricultural area with a fast-growing population. Though traditionally irrigated with surface water, the delta increasingly relies on groundwater. However, saline groundwater extends far land inward, rendering groundwater close to the coastal zone useless for consumption or agriculture. To aid groundwater management decisions, hydrogeologists reconstructed this saline and brackish groundwater zone using variable-density groundwater models with very large dispersivities. However, this approach cannot explain the observed freshening of this zone as observed by hydrogeochemists, who hypothesize that the coastal saline zone is the effect of the Holocene transgression. Here, we investigated physical plausibility of this hypothesis by conducting a palaeo-reconstruction of groundwater salinity for the last 32 ka with a complex 3D variable-density groundwater flow model, using state-of-the-art model code that allows for parallel computation. Several scenarios with different lithologies and hypersaline groundwater provenances were simulated, of which five were selected that showed the best match with the observations. Amongst these selections, total fresh water volumes varied strongly, ranging from 1526 to 2659 km3, mainly due to uncertainties in the lithology offshore and at larger depths. This range is smaller (1511-1989 km3) when we consider the volumes of onshore fresh groundwater within 300 m depth. Regardless of the variance, in all cases the total volume of hypersaline groundwater exceeded that of sea water. We also show that during the last 32 ka, the total fresh groundwater volumes significantly declined, with a factor ranging from 1.9 to 5.4, due to the rising sea-level. Compared to a steady-state solution with present-day boundary conditions, the palaeo-reconstruction improved our validation for the saline zone (5 g/L – 35 g/L TDS). Also, under highly permeable conditions the marine transgression simulated with the palaeo-reconstruction led to a steeper fresh-salt interface compared to its steady-state equivalent, while low permeable clay layers allowed for the preservation of volumes of fresh groundwater. This shows that long-term transient simulations are needed when estimating present-day fresh-salt groundwater distribution in large deltas. The insights of this study are also applicable to other major deltaic areas, given the wide-range of lithological model scenarios used in this study and since many deltas also experienced a Holocene marine transgression.
Unlikely existence of $k_x^{-1}$ spectral law in wall turbulence: an observation of the atmospheric surface layer

description: For wall turbulence, there has been predicted a range of streamwise wavenumbers $k_x$ such that the spectral density of streamwise velocity fluctuations is proportional to $k_x^{-1}$. The existence or nonexistence of this $k_x^{-1}$ law is examined here. We observe the atmospheric surface layer over several months, select suitable data, and use them to synthesize the energy spectrum that would represent wall turbulence at a very high Reynolds number. The result is not consistent with the $k_x^{-1}$ law. It is rather consistent with a recent correction to the prediction of a model of energy-containing eddies that are attached to the wall. The reason for these findings is discussed mathematically.
