description: We consider a model of transverse momentum production in which non-perturbative smearing takes place throughout the perturbative evolution, by a simple modification to an initial state parton shower algorithm. Using this as the important non-perturbative ingredient, we get a good fit to data over a wide range of energy. Combining it with the non-perturbative masses and cutoffs that are a feature of conventional parton showers also leads to a reasonable fit. We discuss the extrapolation to the LHC.

Strong reduction of field-dependent microwave surface resistance in YBa$_{2}$Cu$_{3}$O$_{7-δ}$ with sub-micrometric BaZrO$_3$ inclusions

description: We observe a strong reduction of the field induced thin film surface resistance measured at high microwave frequency ($ν=$47.7 GHz) in YBa$_{2}$Cu$_{3}$O$_{7-δ}$ thin films grown on SrTiO$_3$ substrates, as a consequence of the introduction of sub-micrometric BaZrO$_3$ particles. The field increase of the surface resistance is smaller by a factor of $\sim$3 in the film with BaZrO$_3$ inclusions, while the zero-field properties are not much affected. Combining surface resistance and surface reactance data we conclude (a) that BaZrO$_3$ inclusions determine very deep and steep pinning wells and (b) that the pinning changes nature with respect to the pure film.

description: This paper evaluates cutterhead design of current tunnel boring machines (TBMs) in considerations with the actual cutting action of discs observed on the most common cutter heads. The discs on the current TBM cutter heads were found to predominantly perform asymmetrical cutting action, which generates excessive sideway forces impairing steering action of the machine. The effective s/p ratios related to actual cutting action of discs emerge to be significantly higher than those of the laboratory-determined values, and this consequently leads to adverse cyclic deepening effect. The gross lateral loads arising from excessive side forces were stated to be minimised if the adjacent discs are arranged to cut in symmetrical position by adopting appropriate cutterhead design methods suggested in this paper. Furthermore, a dynamic analysis was carried out in terms of reaction forces on cutter heads of different geometries, and it was indicated that flat face cutter heads have better steering abilities than conical or domed types, in mixed face conditions. Similar analysis on disc angular spacing also inferred that scattered type disc arrangements with equal angular spacing are preferable to cutterheads with spoke or star type lacing, in terms of cutterhead balance.

description: Given an undirected graph with two different nonnegative costs associated with every edge e (say, we for the weight and l e for the length of edge e) and a budget L, consider the problem of finding a spanning tree of total edge length at most L and minimum total weight under this restriction. This constrained minimum spanning tree problem is weakly NP-hard. We present a polynomial-time approximation scheme for this problem. This algorithm always produces a spanning tree of total length at most (1 + ε)L and of total weight at most that of any spanning tree of total length at most L, for any fixed ε >0. The algorithm uses Lagrangean relaxation, and exploits adjacency relations for matroids.

description: House Concurrent Resolution 133 required the Federal Reserve to break with past secrecy by announcing proposed annual growth rates for 'monetary aggregates' four times a year. Earlier the central banks of Germany and Switzerland announced intended annual average growth rates for a specific monetary aggregate.1 Later, central banks in Canada, France, Japan, Britain and elsewhere made similar decisions. I shall refer to all the monetary aggregates as 'money' to avoid excessive emphasis on details, and describe the change in policy as a decision to use money as the principal indicator of monetary policy as defined in Brunner and Meltzer (1967). The central banks of the various countries now set a target rate of interest, level of free liquid reserves, exchange rate or some other market variable that is thought to be consistent with a desired rate of growth of money. The desired growth rate of money is not an end but is a means to achieve some anticipated rate inflation and pace of economic activity in the near future - in the course of the next year or two.

description: We consider higher dimensional operators due to quantum gravity or spontaneous compactification of extra dimensions in Kaluza-Klein type theory and their effect in the $SO(10)$ Lagrangian. These operators change the boundary conditions at the unification scale. As a result one can allow left-right symmetry to survive till very low energy (as low as $\sim$ TeV) for a wide range of values for the coupling of these higher dimensional operators and still make the theory compatible with the latest values of $\sin^2 θ_W$ and $α_s$ derived from LEP. We consider both non-supersymmetric and supersymmetric cases with standard higgses. Proton lifetime is very large in these theories.

description: Submillimeter Galaxies (SMGs) at high redshift are among the best targets to investigate the early evolutionary phases in the lifetime of massive systems, during which large gas reservoirs sustain vigorous star formation and efficiently feed the central, buried Super Massive Black Hole (SMBH).
 I present the analysis of new ALMA band 4 (1.8-2.4 mm) continuum and high-J CO observation of six obscured QSOs (log N_H > 23) hosted by SMGs at z > 2.5 in the 7 Ms Chandra Deep Field South (CDF-S). Sizes and masses of the galaxies are measured to estimate to which extent the host ISM may contribute to the nuclear absorption. We found that at high redshift the galaxy ISM can substantially contribute to the AGN obscuration up to the Compton-thick (10^24 cm^-2) regime. In addition, we found that all the detected sources show a velocity gradient possibly ascribed to a rotating system, even though two of them could be even associated with a chaotic, possibly merging, structure.

description: We present measurements of the dynamical structure factor $S(q,ω)$ of an interacting one-dimensional (1D) Fermi gas for small excitation energies. We use the two lowest hyperfine levels of the $^6$Li atom to form a pseudo-spin-1/2 system whose s-wave interactions are tunable via a Feshbach resonance. The atoms are confined to 1D by a two-dimensional optical lattice. Bragg spectroscopy is used to measure a response of the gas to density ("charge") mode excitations at a momentum $q$ and frequency $ω$. The spectrum is obtained by varying $ω$, while the angle between two laser beams determines $q$, which is fixed to be less than the Fermi momentum $k_\textrm{F}$. The measurements agree well with Tomonaga-Luttinger theory.

description: In this work, we have studied the total scattering cross section ($σ$), differential scattering cross section ($dσ/dQ^2$) as well as the longitudinal ($P_L(E_e,Q^2)$), perpendicular ($P_P(E_e,Q^2)$), and transverse ($P_T(E_e,Q^2)$) components of the polarization of the final hadron ($n$, $ Λ$ and $Σ^0$) produced in the electron proton scattering induced by the weak charged current. We have not assumed T-invariance which allows the transverse component of the hadron polarization perpendicular to the production plane to be non-zero. The numerical results are presented for all the above observables and their dependence on the axial vector form factor and the weak electric form factor are discussed. The present study enables the determination of the axial vector nucleon-hyperon transition form factors at high $ Q^2$ in the strangeness sector which can provide test of the symmetries of the weak hadronic currents like T-invariance and SU(3) symmetry while assuming the hypothesis of conserved vector current and partial conservation of axial vector current.

description: Context : A 1000-s flare from a new hard X-ray transient, IGR J08408-4503, was observed by INTEGRAL on May 15, 2006 during the real-time routine monitoring of IBIS/ISGRI images performed at the INTEGRAL Science Data Centre. The flare, detected during a single one-hour long pointing, peaked at 250 mCrab in the 20-40 keV energy range. Aims : Multi-wavelength observations, combining high-energy and optical data, were used to unveil the nature of IGR J08408-4503. Methods : A search in all INTEGRAL public data for other bursts from IGR J08408-4503 was performed, and the detailed analysis of another major flare is presented. The results of two Swift Target of Opportunity observations are also described. Finally, a study of the likely optical counterpart, HD 74194, is provided. Results : IGR J08408-4503 is very likely a supergiant fast X-ray transient (SFXT) system. The system parameters indicate that the X-ray flares are probably related to the accretion of wind clumps on a compact object orbiting about 1E13 cm from the supergiant HD 74194. The clump mass loss rate is of the order of 1E-6 solar mass/yr. Conclusions : Hard X-ray flares from SFXTs allow to probe the stellar winds of massive stars, and could possibly be associated with wind perturbations due to line-driven instabilities.

description: Three-dimensional tomography of hadrons can be investigated by generalized parton distributions (GPDs), transverse-momentum-dependent parton distributions (TMDs), and generalized distribution amplitudes (GDAs). The GDA studies had been only theoretical for a long time because there was no experimental measurement until recently, whereas the GPDs and TMDs have been investigated extensively by deeply virtual Compton scattering and semi-inclusive deep inelastic scattering. Here, we report our studies to determine pion GDAs from recent KEKB measurements on the differential cross section of $γ^* γ\to π^0 π^0$. Since an exotic-hadron pair can be produced in the final state, the GDAs can be used also for probing internal structure of exotic hadron candidates in future. The other important feature of the GDAs is that the GDAs contain information on form factors of the energy-momentum tensor for quarks and gluons, so that gravitational form factors and radii can be calculated from the determined GDAs. We show the mass (energy) and the mechanical (pressure, shear force) form factors and radii for the pion. Our analysis should be the first attempt for obtaining gravitational form factors and radii of hadrons by analysis of actual experimental measurements. We believe that a new field of gravitational physics is created from the microscopic level in terms of elementary quarks and gluons.

description: [transcription] A Aix ce 17 janvier 1771

Je prens la liberté, Monsieur, de vous offrir quelque chose qui est bien peu digne de vous, et il faut compter beaucoup sur votre indulgence pour vous faire un pareil présent. J'ai ramassé depuis quelques années un grand nombre de monnaies de nos comtes de Provence et des seigneurs spirituels et temporels qui avaient droit d'y battre monnaies dans nos provinces méridionales. Comme les collections ne sont jamais en sûreté dans les mains des particuliers et qu'elles sont dissipées tôt ou tard, j'ai voulu fixer celle-là en la faisant graver. J'ai été mal secondé par l'artiste qui est un homme de 15 ans qui n'avait jamais touché le burin. Ses gravures n'ont de mérite que la plus grande exactitude. J'ai tout fait faire sous mes yeux et il y a des planches que j'ai faitrefaire en entier plusieurs [fol. 145v] fois. J'yai joint une table du poids, du titre et de la valeur des espèces que j'ai dressé sur une infinité de pièces justificatives que j'ai ramassé sur cette matière. J'avais dressé un mémoire historique sur nos monnaies qui joint à ces pièces justificatives, aurait fait un petit in quarto. Mais toute réflexion faite, j'ai cru que ce n'était pas la peine de multiplier les livres sur des objets qui tentent aussi peu la curiosité du public. La découverte d'une médaille grecque ou romaine qui n'a jamais paruétait inconnue, fait un événement dans la littérature. Mais on se moquerait de moi si je m'avisais de dire que j'ai dans mon cabinet plus de trois cents monnaies qui intéressent notre histoire et qui n'ont jamais été publiées. Je sais qu'il m'a échappé un grand nombre de monnaies de votre province. Je vous serais bien obligé si vous pouviez me procurer le moyen de les acquérir à [fol. 146] tout prix ou tout au moins si vous pouviez m'en faire avoir des dessins. Je n'épargne niargent nipeine pour augmenter ma collection. Pardonnez-moi je vous prie l'aveu de mes misères. Vous m'avez depuis longtems accoutumé à abuser de vos bontés, continuez-les moi je vous en prie. Soyez persuadé de ma sincère reconnaissance et de l'attachement respectueux avec lequel j'ai l'honneur d'être, Monsieur, votre très humble et très obéissant serviteur.

description: The Jordan--Wigner transformation plays an important role in spin models. However, the non-locality of the transformation implies that a periodic chain of $N$ spins is not mapped to a periodic or an anti-periodic chain of lattice fermions. Since only the $N-1$ bond is different, the effect is negligible for large systems, while it is significant for small systems. In this paper, it is interesting to find that a class of periodic spin chains can be exactly mapped to a periodic chain and an anti-periodic chain of lattice fermions without redundancy when the Jordan--Wigner transformation is implemented. For these systems, possible high degeneracy is found to appear in not only the ground state but also the excitation states. Further, we take the one-dimensional compass model and a new XY-XY model ($σ_xσ_y-σ_xσ_y$) as examples to demonstrate our proposition. Except for the well-known one-dimensional compass model, we will see that in the XY-XY model, the degeneracy also grows exponentially with the number of sites.

Differential expression analysis of lysosomal storage related genes in gliomas
Creators: name: Silva, Gerda Cristal Villalba
name: Matte, Ursula Da Silveira
Publisher: name: F1000 Research Limited
Year: 2019

description: Introduction: Defects in activity and transport of lysosomal hydrolases lead to the accumulation of lysosomal metabolites, causing lysosomal storage disease (LSD). The involvement of lysosomes also has been described in tumors, related to cell proliferation and signaling processes, microbial killing, cytotoxic killing, induction of angiogenesis, cell adhesion and metastatic processes. Aims: This work aims to investigate the differential expression of lysosomal genes and autophagy-related genes in brain tumors. Data from patients with different brain tumors were collected and analyzed through the R2: Genomics Analysis and Visualization Platform. Gene expression analysis was performed on 50 gliomas with five pathological diagnosis. Sample tracks were divided in recurrence of progression and description of the tumor. All differentially expressed genes were correlated with survival rates using Kaplan Meier. Results: From 113 selected genes (KEGG pathway: lysosome), 24 were up-regulated and 6 were down-regulated. Heatmap analysis showed that 30 genes have a distinct pattern for grade IV glioblastoma multiforme. Survival analysis showed that cathepsin expression correlates with poor survival, as previously shown for other tumors. In addition, similar results were found for different lysosomal hydrolases, such as Beta-Manosidase, Galactosidase, Glucorunidase beta, and, Hexosaminidase, and autophagy-related genes. Conclusion: Studying the lysosomal signature in tumors may help understand the mechanisms by which neurological dysfunction occurs both in patients with neurological tumors and in patients with lysosomal storage diseases. Besides, differentially expressed genes may serve as prognostic biomarkers and therapeutic targets. Also, may improve diagnosis and lead patients to a more adequate treatment.

description: The quantum statistical approach proposed more than one decade ago was used to determine the parton distributions for the proton by considering a large set of accurate Deep Inelastic Scattering experimental results. We propose to extend this work to extract the parton distributions for the pion by using data on lepton pair production from various experiments. This global next-to-leading order QCD analysis leads to a good description of several Drell-Yan $π^- W$ data. The resulting parton distributions are compared with earlier determinations. We will also discuss the difference between nucleon and pion structure in the same approach.

description: The differential and total cross sections for kaon pair production in the pp->ppK+K- reaction have been measured at three beam energies of 2.65, 2.70, and 2.83 GeV using the ANKE magnetic spectrometer at the COSY-Juelich accelerator. These near-threshold data are separated into pairs arising from the decay of the phi-meson and the remainder. For the non-phi selection, the ratio of the differential cross sections in terms of the K-p and K+p invariant masses is strongly peaked towards low masses. This effect can be described quantitatively by using a simple ansatz for the K-p final state interaction, where it is seen that the data are sensitive to the magnitude of an effective K-p scattering length. When allowance is made for a small number of phi events where the K- rescatters from the proton, the phi region is equally well described at all three energies. A very similar phenomenon is discovered in the ratio of the cross sections as functions of the K-pp and K+pp invariant masses and the identical final state interaction model is also very successful here. The world data on the energy dependence of the non-phi total cross section is also reproduced, except possibly for the results closest to threshold.

The rhythms of life: Identifying a role for the circadian regulator UBR4 in cardiac arrhythmia

description: Lay Summary
Long QT syndrome is one of a group of diseases called cardiac arrhythmias, where the heart fails to maintain the correct rhythm. Biological rhythms are central to life, and cardiac rhythms are examples of high frequency or ultradian rhythms. A candidate gene involved in Long QT syndrome is UBR4. This gene is highly conserved between different species, and has been implicated to be involved in maintaining daily, or circadian, rhythms in species as diverse as plants and mouse. In humans UBR4 has been shown to be strongly expressed in the heart and brain. This project looks to identify inherited variants in UBR4 in the 100,000 genomes dataset, to identify if any patients suffering from cardiac arrhythmias carry inherited pathogenic variants in UBR4. We have additionally developed a zebrafish circadian disease model to test specific parts of the protein that are implicated as being pathogenic if disrupted. This allows us to test if there is a link between the mistiming of biological rhythms on a short and daily time scale.

Summary Abstract
Ubiquitin Protein Ligase E3 Component N-Recognin 4 (UBR4) is a single copy gene highly conserved between animals and plants. In plants the homologue has been demonstrated to regulate the circadian clock and play a role in photoperiodism (Hearn et al., 2018. Plant Phys. 178(1):358-371). In animals UBR4 has been shown to have photoperiodic regulation, and to be involved in circadian signal transduction in the SCN (Ling et al., 2014. PLoS One. 1;9(8):e103103). UBR4 is expressed most strongly in the brain and heart, and variants in UBR4 have been reported as pathogenic candidates in cardiac arrhythmia patients with Long QT syndrome (Shigemizu et al., 2015. PLoS One. 1;10(7):e0130329). Long QT syndrome Type 3 is a good candidate for a disease with a circadian basis as it is typically characterised by cardiac arrest during sleep. Identifying a circadian basis for a disease would allow the development of chronotherapeutic disease management. In this project we characterise the human UBR4 gene and identify pathogenic variants in the 100,000 genomes dataset, looking at the subset of patients with cardiac arrhythmia. We further test the pathogenicity of UBR4 by targeted CRISPR disruption of key domains in a zebrafish circadian disease model. This initial project in identifying circadian disease genes is a starting block for our further work in comparative chronomics.

description: Van der Waals heterostructure based on layered two-dimensional (2D) materials offers unprecedented opportunities to create materials with atomic precision by design. By combining superior properties of each component, such heterostructure also provides possible solutions to address various challenges of the electronic devices, especially those with vertical multilayered structures. Here, we report the realization of robust memristors for the first time based on van der Waals heterostructure of fully layered 2D materials (graphene/MoS2-xOx/graphene) and demonstrate a good thermal stability lacking in traditional memristors. Such devices have shown excellent switching performance with endurance up to 107 and a record-high operating temperature up to 340oC. By combining in situ high-resolution TEM and STEM studies, we have shown that the MoS2-xOx switching layer, together with the graphene electrodes and their atomically sharp interfaces, are responsible for the observed thermal stability at elevated temperatures. A well-defined conduction channel and a switching mechanism based on the migration of oxygen ions were also revealed. In addition, the fully layered 2D materials offer a good mechanical flexibility for flexible electronic applications, manifested by our experimental demonstration of a good endurance against over 1000 bending cycles. Our results showcase a general and encouraging pathway toward engineering desired device properties by using 2D van der Waals heterostructures.

On monodromy representation of period integrals associated to an algebraic curve with bi-degree (2,2)

description: We study a problem related to Kontsevich's homological mirror symmetry conjecture for the case of a generic curve $\cal Y$ with bi-degree (2,2) in a product of projective lines ${\Bbb P}^{1} \times {\Bbb P}^{1}$. We calculate two differenent monodromy representations of period integrals for the affine variety ${\cal X}^{(2,2)}$ obtained by the dual polyhedron mirror variety construction from $\cal Y$. The first method that gives a full representation of the fundamental group of the complement to singular loci relies on the generalised Picard-Lefschetz theorem. The second method uses the analytic continuation of the Mellin-Barnes integrals that gives us a proper subgroup of the monodromy group. It turns out both representations admit a Hermitian quadratic invariant form that is given by a Gram matrix of a split generator of the derived category of coherent sheaves on on $\cal Y$ with respect to the Euler form.
Collaboratively Weighting Deep and Classic Representation via L2 Regularization for Image Classification

description: Deep convolutional neural networks provide a powerful feature learning capability for image classification. The deep image features can be utilized to deal with many image understanding tasks like image classification and object recognition. However, the robustness obtained in one dataset can be hardly reproduced in the other domain, which leads to inefficient models far from state-of-the-art. We propose a deep collaborative weight-based classification (DeepCWC) method to resolve this problem, by providing a novel option to fully take advantage of deep features in classic machine learning. It firstly performs the L2-norm based collaborative representation on the original images, as well as the deep features extracted by deep CNN models. Then, two distance vectors, obtained based on the pair of linear representations, are fused together via a novel collaborative weight. This collaborative weight enables deep and classic representations to weigh each other. We observed the complementarity between two representations in a series of experiments on 10 facial and object datasets. The proposed DeepCWC produces very promising classification results, and outperforms many other benchmark methods, especially the ones claimed for Fashion-MNIST. The code is going to be published in our public repository.

The Choice of the Monetary Regime

description: The principles guiding the choice of a monetary regime or constitution have remained an unresolved issue in the theories of money and economic policy. The student of money confronts four formidable obstacles what addressing this issue as an application of economic theory. First, money is not only neutral in monetary theory, but it is one of many, undifferentiated commodities without any particular properties that can affect the economy's equilibrium. Any commodity chosen at random provides money services as well as any other. Second, although the choice of monetary institutions or a monetary standard can have real effects in practice, these effects are excluded from formal economic theory by the assumption of continuous market clearing and by making the competitive equilibrium independent of real world institutions. Third, relevant aspects of uncertainty that give rise to costly information are missing. At most, individuals hold certain expectations about all possible future contingencies. Fourth, a representative agent makes all decisions, bears all costs, and receives all benefits. There are no effects of redistribution through inflation or deflation. In this framework the choice of a monetary constitution is uninteresting.

description: Inflation is usually defined as a sustained rate of increase in a broadly based index of prices. Whatever meaning one gives to the imprecise term "sustained," the past fifteen years seem to meet the standard. Both the all-item consumer price index and the implicit GNP deflator have increased in every quarter since late 1965, and neither seems likely to reach a zero rate of change in the near future.
Topological susceptibility and string tension in the lattice CP(N) models

description: In the lattice CP(N) models we studied the problems related to the measure of the topological susceptibility and the string tension . We perfomed numerical simulations at N=4 and N=10. In order to test the universality, we adopted two different lattice formulations. Scaling and universality tests led to the conclusion that at N=10 the geometrical approach gives a good definition of lattice topological susceptibility. On the other hand, N=4 proved not to be large enough to suppress the unphysical configurations, called dislocations, contributing to the topological susceptibility. We obtained other determinations of the topological susceptibility by the field theoretical method, wich relies on a local definition of the lattice topological charge density, and the cooling method. They gave quite consistent results, showing scaling and universality. The large-N expansion predicts an exponential area law behavior for sufficiently large Wilson loops, which implies confinement, due to the dynamical matter fields and absence of the screening phenomenon. We determined the string tension, without finding evidence of screening effects.

Photon Correlation Spectroscopy for Observing Natural Lasers

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

description: Natural laser emission may be produced whenever suitable atomic energy levels become overpopulated. Strong evidence for laser emission exists in astronomical sources such as Eta Carinae, and other luminous stars. However, the evidence is indirect in that the laser lines have not yet been spectrally resolved. The lines are theoretically estimated to be extremely narrow, requiring spectral resolutions very much higher (R approx.= 10**8) than possible with ordinary spectroscopy. Such can be attained with photon-correlation spectroscopy on nanosecond timescales, measuring the autocorrelation function of photon arrival times to obtain the coherence time of light, and thus the spectral linewidth. A particular advantage is the insensitivity to spectral, spatial, and temporal shifts of emission-line components due to local velocities and probable variability of 'hot-spots' in the source. A laboratory experiment has been set up, simulating telescopic observations of cosmic laser emission. Numerically simulated observations estimate how laser emission components within realistic spectral and spatial passbands for various candidate sources carry over to observable statistical functions.

description: It is demonstrated that any attempt to calculate the perturbative QCD contribution to the pion form factor requires the inclusion of intrinsic transverse momentum besides Sudakov form factors. For momentum transfers of the order of a few GeV the intrinsic transverse momentum leads to a substantial suppression of the perturbative QCD contribution.

Structural and Dynamical Properties of Galaxies in a Hierarchical Universe: Sizes and Specific Angular Momenta

description: We use a state-of-the-art semi-analytic model to study the size and the specific angular momentum of galaxies. Our model includes a specific treatment for the angular momentum exchange between different galactic components. Disk scale radii are estimated from the angular momentum of the gaseous/stellar disk, while bulge sizes are estimated assuming energy conservation. The predicted size--mass and angular momentum--mass relations are in fair agreement with observational measurements in the local Universe, provided a treatment for gas dissipation during major mergers is included. Our treatment for disk instability leads to unrealistically small radii of bulges formed through this channel, and predicts an offset between the size--mass relations of central and satellite early-type galaxies, that is not observed. The model reproduces the observed dependence of the size--mass relation on morphology, and predicts a strong correlation between specific angular momentum and cold gas content. This correlation is a natural consequence of galaxy evolution: gas-rich galaxies reside in smaller halos, and form stars gradually until present day, while gas-poor ones reside in massive halos, that formed most of their stars at early epochs, when the angular momentum of their parent halos is low. The dynamical and structural properties of galaxies can be strongly affected by a different treatment for stellar feedback, as this would modify their star formation history. A higher angular momentum for gas accreted through rapid mode does not affect significantly the properties of massive galaxies today, but has a more important effect on low-mass galaxies at higher redshift.
