description:

Il presente lavoro esamina il ruolo della cultura aziendale nelle fusioni e acquisizioni, sia in termini di probabilità di essere coinvolti in un’operazione, sia in termini di esito della stessa. Lo studio dimostra che una cultura aziendale orientata verso l’esterno, quindi attenta alla creazione di valore per gli azionisti e al rapporto con i competitor, aumenta significativamente la probabilità di partecipare ad operazioni di M&A, ma ha un impatto negativo sulla loro capacità di generare valore. Tale evidenza viene confermata tramite l’utilizzo di un esperimento naturale che considera uno shock esogeno alla cultura aziendale, proveniente dall’approvazione di diverse leggi sul congedo parentale negli Stati Uniti. I nostri risultati suggeriscono che le aziende orientate all'esterno sottovalutano la possibilità di scontri culturali dopo una fusione e hanno maggiori probabilità di concludere accordi che distruggono valore.
On the time variability of geometrically-thin black hole accretion disks I : the search for modes in simulated disks

description: We present a detailed temporal analysis of a set of hydrodynamic and magnetohydrodynamic (MHD) simulations of geometrically-thin (h/r~0.05) black hole accretion disks. The black hole potential is approximated by the Paczynski-Wiita pseudo-Newtonian potential. In particular, we use our simulations to critically assess two widely discussed models for high-frequency quasi-periodic oscillations, global oscillation modes (diskoseismology) and parametric resonance instabilities. We find that initially disturbed hydrodynamic disks clearly display the trapped global g-mode oscillation predicted by linear perturbation theory. In contrast, the sustained turbulence produced in the simulated MHD disks by the magneto-rotational instability does not excite these trapped g-modes. We cannot say at present whether the MHD turbulence actively damps the hydrodynamic g-mode. Our simulated MHD disks also fail to display any indications of a parametric resonance instability between the vertical and radial epicyclic frequencies. On the other hand, we do see characteristic frequencies at any given radius in the disk corresponding to local acoustic waves. We also conduct a blind search for any quasi-periodic oscillation in a proxy lightcurve based on the instantaneous mass accretion rate of the black hole, and place an upper limit of 2% on the total power in any such feature. We highlight the importance of correcting for secular changes in the simulated accretion disk when performing temporal analyses.

description: Continuous double auctions such as the limit order book employed by exchanges are widely used in practice to match buyers and sellers of a variety of financial instruments. In this work, we develop an agent-based model for trading in a limit order book and show (1) how opponent modelling techniques can be applied to classify trading agent archetypes and (2) how behavioural cloning can be used to imitate these agents in a simulated setting. We experimentally compare a number of techniques for both tasks and evaluate their applicability and use in real-world scenarios.
Background Independent Field Quantization with Sequences of Gravity-Coupled Approximants II: Metric Fluctuations

description: We apply the new quantization scheme outlined in Phys. Rev. D102 (2020) 125001 to explore the influence which quantum vacuum fluctuations of the spacetime metric exert on the universes of Quantum Einstein Gravity, which is regarded an effective theory here. The scheme promotes the principle of Background Independence to the level of the regularized precursors of a quantum field theory ("approximants") and severely constrains admissible regularization schemes. Without any tuning of parameters, we find that the zero point oscillations of linear gravitons on maximally symmetric spacetimes do not create the commonly expected cosmological constant problem of a cutoff-size curvature. On the contrary, metric fluctuations are found to reduce positive curvatures to arbitrarily tiny and ultimately vanishing values when the cutoff is lifted. This suggests that flat space could be the distinguished groundstate of pure quantum gravity. Our results contradict traditional beliefs founded upon background-dependent calculations whose validity must be called into question therefore.

description: Liver cancer is one of the most malignant cancers in the world, and a relapse rate up to 60~70% after resection is a major factor contributing to a low 5-year survival rate (~15%). We generated more than 20,000 single-cell full-length transcriptomes profiles from 19 primary or relapsed hepatocellular carcinoma (HCC) patients, to determine the landscape of the tumor microenvironment in relapsed HCC, as well as a comparison with primary HCC. We discovered that relapsed lesions have a unique immune composition as compared to the primary tumor, with a lower abundance of Tregs, a higher ratio of dendritic cells (DCs), and more infiltrated CD8+ than CD4+ T cells. In addition, we found that CD8+ T cells in the primary and relapsed tumor have the same transition path, but were in different states, CD8+ T cells from relapsed tumor showing an innate lymphoid cell (ILC)-like state, with a high naïve signal and low cytotoxic and exhausted signals. Further analysis also indicates that the abundance of distinct DC subtypes is associated with good prognosis in both primary and relapsed HCC. Also, FCN1+ monocytes are associated with poor prognosis only in relapsed HCC and not in primary HCC. Differential analysis between primary and relapsed tumor cells in gene expression level and interactions with other cells also reveals potential different immune evasion and tumor survival strategies in relapsed and primary HCC. Together these results provide a compressive understanding of the ecosystem in primary and relapsed HCC tumors, which could be used to guide future immune therapy strategies.

description: The homogeneous shear of the {111} planes along the <110> direction of bulk silicon has been investigated using ab initio techniques, to better understand the strain properties of both shuffle and glide set planes. Similar calculations have been done with three empirical potentials, Stillinger-Weber, Tersoff and EDIP, in order to find the one giving the best results under large shear strains. The generalized stacking fault energies have also been calculated with these potentials to complement this study. It turns out that the Stillinger-Weber potential better reproduces the ab initio results, for the smoothness and the amplitude of the energy variation as well as the localization of shear in the shuffle set.
$J/ψ$ suppression and $p_T$ spectra in RHIC and LHC energy collisions

description: In a hydrodynamic model, we have studied $J/ψ$ production in Au+Au/Cu+Cu collisions at RHIC energy $\sqrt{s}$=200 GeV. At the initial time, $J/ψ$'s are randomly distributed in the fluid. As the fluid evolve in time, the free streaming $J/ψ$'s are dissolved if the local fluid temperature exceeds a threshold temperature $T_{J/ψ}$. Sequential melting of charmonium states ($χ_c$, $ψ\prime$ and $J/ψ$), with melting temperatures $T_{χ_c}=T_{ψ\prime} \approx 1.2T_c$, $T_{J/ψ} \approx2T_c$ and feed-down fraction $F\approx 0.3$, explains the PHENIX data on the centrality dependence of $J/ψ$ suppression in Au+Au collisions. $J/ψ$ $p_T$ spectra and the nuclear modification factor in Au+Au collisions are also well explained in the model. The model however over predict centrality dependence of $J/ψ$ suppression in Cu+Cu collisions by 20-30%. The $J/ψ$ $p_T$ spectra are under predicted by 20-30%. The model predict that in central Pb+Pb collisions at LHC energy, $\sqrt{s}$=5500 GeV, $J/ψ$'s are suppressed by a factor of $\sim$ 10. The model predicted $J/ψ$ $p_T$ distribution in Pb+Pb collisions at LHC is similar to that in Au+Au collisions at RHIC.

description: The DEK oncoprotein is a ubiquitous nuclear factor that has been consistently associated with tumor progression: its expression level differs between normal and cancer cells (1), raising the possibility of using DEK as a tumor marker (2). Moreover, DEK is a non-histone architectural chromatin factor that may influence nucleosomal accessibility and therefore gene activity (3). The interest of this work is to investigate, using super-resolution microscopy approaches, the correlation between the organization of the DEK oncoprotein and the local chromatin structure depending on the degree of cell malignancy. A model based on three well-established human breast cell lines was chosen to represent different subtypes of breast cancer (MCF10A, MCF7 and MDA-MB-231 cells). We performed dual-color confocal and STED imaging followed by the pixel intensity spatial correlation analysis (4), to show the differences of the nanoscale distribution of DEK in relation to the chromatin organization pattern (observed by particular histone modification immunostaining). We expect that this study will provide novel insights into the tumor-promoting activity of DEK and thus progress our understanding of basic mechanisms of cancerogenesis.

description: We propose a two-dimensional time-reversal invariant system of essentially non-interacting electrons on a square lattice that exhibits configurations with fractional charges e/2. These are vortex-like topological defects in the dimerization order parameter describing spatial modulation in the electron hopping amplitudes. Charge fractionalization is established by a simple counting argument, analytical calculation within the effective low-energy theory, and by an exact numerical diagonalization of the lattice Hamiltonian. We comment on the exchange statistics of fractional charges and possible realizations of the system.

description: Using first principles, classical potentials, and elasticity theory, we investigated the structure of a semiconductor/semiconductor interface with a high lattice mismatch, SiC/Si(001). Among several tested possible configurations, a heterostructure with (i) a misfit dislocation network pinned at the interface and (ii) reconstructed dislocation cores with a carbon substoichiometry is found to be the most stable one. The importance of the slab approximation in first-principles calculations is discussed and estimated by combining classical potential techniques and elasticity theory. For the most stable configuration, an estimate of the interface energy is given. Finally, the electronic structure is investigated and discussed in relation with the dislocation array structure. Interface states, localized in the heterostructure gap and located on dislocation cores, are identified.

description: Black hole formation in a core-collapse supernova is expected to lead to a distinctive, abrupt drop in neutrino luminosity due to the engulfment of the main neutrino-producing regions as well as the strong gravitational redshift of those remaining neutrinos which do escape. Previous analyses of the shape of the cut-off have focused on specific trajectories or simplified models of bulk neutrino transport. In this article, we integrate over simple "ballistic" geodesics to investigate potential effects on the cut-off profile of including all neutrino emission angles from a collapsing surface in the Schwarzschild metric, and from a contracting equatorial mass ring in the Kerr metric. We find that the non-radial geodesics contribute to a softening of the cut-off in both cases. In addition, extreme rotation introduces significant changes to the shape of the tail which may be observable in future neutrino detectors, or combinations of detectors.

description: A gravitational shock wave is a solution to Einstein equations describing the gravitational field of a massless particle. We obtain such a geometry for a particle moving on a AdS_3 brane embedded in a AdS_4 bulk (the lower dimensional version of the "locally localized gravity" model of Karch and Randall). In order to do this, we use two different techniques. First, we solve directly Einstein equations sourced by a massless particle. Then we boost to the speed of light the AdS_3 brane black hole solution of Emparan et al while sending its mass parameter to zero. Surprisingly, we obtain two different results. We discuss the origin of these two different solutions both in the bulk and in the CFT picture. As a by-product, we derive the expression for the shock wave associated to a transversally accelerating particle in AdS_4.

Very Broad [O III]4959,5007 Emission from the NGC 4472 Globular Cluster RZ2109 and Implications for the Mass of Its Black Hole X-ray Source

description: We present Keck LRIS spectroscopy of the black hole-hosting globular cluster RZ2109 in the Virgo elliptical galaxy NGC 4472. We find that this object has extraordinarily broad [OIII]5007 and [OIII]4959 emission lines, with velocity widths of approximately 2,000 k/ms. This result has significant implications for the nature of this accreting black-hole system and the mass of the globular cluster black hole. We show that the broad [OIII]5007 emission must arise from material driven at high velocity from the black hole system. This is because the volume available near the black hole is too small by many orders of magnitude to have enough [OIII] emitting atoms to account for the observed L([OIII]5007) at high velocities, even if this volume is filled with Oxygen at the critical density for [OIII]5007. The Balmer emission is also weak, indicating the observed [OIII] is not due to shocks. We therefore conclude that the [OIII]4959,5007 is produced by photoionization of material driven across the cluster. The only known way to drive significant material at high velocity is for a system accreting mass near or above its Eddington limit, which indicates a stellar mass black hole. Since it is dynamically implausible to form an accreting stellar mass black hole system in a globular cluster with an intermediate mass black hole (IMBH), it appears this massive globular cluster does not have an IMBH. We discuss further tests of this conclusion, and its implications for the M_BH - M_stellar and M_BH - sigma relations.

description: It is well-known that the electric and magnetic Aharonov-Bohm effects may be formally described on equal footing using the four-vector potential in a relativistic framework. We propose an illustrative manifestation of both effects in a single configuration, in which the specific path of the charged particle determines the weight of the electric and magnetic acquired relative phases. The phases can be distinctively obtained in the Coulomb gauge. The scheme manifests the pedagogical lesson that though each of the relative phases is gauge-dependent their sum is gauge-invariant.

description: Quantum catalytic transformations play important roles in the transformation of quantum entangled states under local operations and classical communications (LOCC). The key problems in catalytic transformations are the existence and the bounds on the catalytic states. We present the necessary conditions of catalytic states based on a set of points given by the Schmidt coefficients of the entangled source and target states. The lower bounds on the dimensions of the catalytic states are also investigated. Moreover, we give a detailed protocol of quantum mixed state transformation under entanglement-assisted LOCC.

description: The universal three-body dynamics in ultra-cold binary gases confined to one-dimensional motion are studied. The three-body binding energies and the (2 + 1)-scattering lengths are calculated for two identical particles of mass $m$ and a different one of mass $m_1$, which interactions is described in the low-energy limit by zero-range potentials. The critical values of the mass ratio $m/m_1$, at which the three-body states arise and the (2 + 1)-scattering length equals zero, are determined both for zero and infinite interaction strength $λ_1$ of the identical particles. A number of exact results are enlisted and asymptotic dependences both for $m/m_1 \to \infty$ and $λ_1 \to -\infty$ are derived. Combining the numerical and analytical results, a schematic diagram showing the number of the three-body bound states and the sign of the (2 + 1)-scattering length in the plane of the mass ratio and interaction-strength ratio is deduced. The results provide a description of the homogeneous and mixed phases of atoms and molecules in dilute binary quantum gases.

description: In this paper we investigate the gravitational-wave generation problem at the first post-Newtonian order in the context of Einstein-Cartan theory by exploiting the Blanchet-Damour formalism. The quantum intrinsic spin carried by slowly moving, weakly stressed, weakly self-gravitating sources is described geometrically by means of the torsion tensor. We obtain the expression of the source multipole moments with the required accuracy. The analysis of the physical meaning of the lowest-order non-radiative moments and of the asymptotic gravitational waveform is also performed. Eventually, we draw our conclusions and estimate the order of magnitude of the spin contributions in the gravitational-wave signal.

description: For a long time, the development model of traditional rice planting industry has been single, linear, and focusing on production first and then market. However, with the low price of rice, such problems as slow technological upgrading, meager profits, and unstable rice quality in the primary industry planting units and farmers have become increasingly prominent. The integration and development of the rural primary, secondary, and tertiary industries and industrial integration have the same root. They are integrated industrial development based on technological or model innovation, vertical and horizontal integration. Three agricultural leading companies (Nanjing Tianwei Agricultural Technology Co., Ltd., Nanjing CHYKINGYOUNG Biological Technology Co., Ltd., and Jiangsu Jingshan Eco-organic Agriculture Co., Ltd.) established an industrialization complex, and used their respective technical, operational, and market advantages to integrate and form a rice contract farming 1 + 3 + X model. This model effectively integrates scattered rice planting, rice processing, and rice sales in Nanjing City of Jiangsu Province, and Chuzhou City of Anhui Province, and unifies planting regulations and supply of production materials, safeguards the supply of green and high-quality rice and realizes high quality and high price. In addition, it integrates farmers into the entire industrial chain of contract farming, summons up the production enthusiasm of farmers and greatly increases their income from planting production.

description: We present an extension of the continuous damage fiber bundle model to describe the gradual degradation of highly heterogeneous materials under an increasing external load. Breaking of a fiber in the model is preceded by a sequence of partial failure events occurring at random threshold values. In order to capture the subsequent propagation and arrest of cracks, furthermore, the disorder of the number of degradation steps of material constituents, the failure thresholds of single fibers are sorted into ascending order and their total number is a Poissonian distributed random variable over the fibers. Analytical and numerical calculations showed that the failure process of the system is governed by extreme value statistics, which has a substantial effect on the macroscopic constitutive behaviour and on the microscopic bursting activity as well.

description: Electronic properties of FeSe can be tuned by various routes. Here, we present a comprehensive study on the evolution of the superconductivity and nematicity in FeSe with thickness from bulk single crystal down to bilayer ($\sim$ 1.1 nm) through exfoliation. With decreasing flake thickness, both the structural transition temperature $T_{\rm s}$ and the superconducting transition temperature $T_{\rm c}^{\rm zero}$ are greatly suppressed. The magnetic field ($B$) dependence of Hall resistance $R_{xy}$ at 15 K changes from $B$-nonlinear to $B$-linear behavior up to 9 T, as the thickness ($d$) is reduced to 13 nm. $T_{\rm c}$ is linearly dependent on the inverse of flake thickness (1/$d$) when $d\le$ 13 nm, and a clear drop of $T_{\rm c}$ appears with thickness smaller than 27 nm. The $I$-$V$ characteristic curves in ultrathin flakes reveal the signature of Berezinskii-Kosterlitz-Thouless (BKT) transition, indicating the presence of two-dimensional superconductivity. Anisotropic magnetoresistance measurements further support 2D superconductivity in few-layer FeSe. Increase of disorder scattering, anisotropic strains and dimensionality effect with reducing the thickness of FeSe flakes, might be taken into account for understanding these behaviors. Our study provides systematic insights into the evolution of the superconducting properties, structural transition and Hall resistance of a superconductor FeSe with flakes thickness and provides an effective way to find two-dimensional superconductivity as well as other 2D novel phenomena.

description: The advantage of having a high-fidelity instrument simulation tool developed in tandem with novel instrumentation is having the ability to investigate, in isolation and in combination, the wide parameter space set by the instrument design. SCALES, the third generation thermal-infrared diffraction limited imager and low/med-resolution integral field spectrograph being designed for Keck, is an instrument unique in design in order to optimize for its driving science case of direct detection and characterization of thermal emission from cold exoplanets. This warranted an end-to-end simulation tool that systematically produces realistic mock data from SCALES to probe the recovery of injected signals under changes in instrument design parameters. In this paper, we quantify optomechanical tolerance and detector electronic requirements set by the fiducial science cases using information content analysis, and test the consequences of updates to the design of the instrument on meeting these requirements.

description: Large-scale atomistic calculations, using empirical potentials for modeling semiconductors, have been performed on a stressed system with linear surface defects like steps. Although the elastic limits of systems with surface defects remain close to the theoretical strength, the results show that these defects weaken the atomic structure, initializing plastic deformations, in particular dislocations. The character of the dislocation nucleated can be predicted considering both the resolved shear stress related to the applied stress orientation and the Peierls stress. At low temperature, only glide events in the shuffle set planes are observed. Then they progressively disappear and are replaced by amorphization/melting zones at a temperature higher than 900 K.

description: In Tibet, the efficiency of beekeeping industry is low, the abundant nectariferous plants and the non-polluting natural ecological environment are not fully utilized, the pollination of rapeseed and other insect-based crops is insufficient, and benefits are not brought by beekeeping. In response to these problems, Italian bees were first introduced since 2004, and combined with the special natural ecological environment of Tibet, researches on Italian bee biology, queen rearing technology, overwintering technology, and breeding management technology were carried out in high altitude areas. Through many years of effort, it has filled the gap in bee breeding technology at an altitude of about 4 000 m and provided a new pillar industry for Tibetan farmers and herdsmen to increase production and income.

description: Η δραστηριότητα των λατομείων στην αρχαιότητα, η οποία αναφέρεται στις διαδικασίες εξόρυξης και διάθεσης των διαφόρων δομικών λίθων, δεν επηρεάζεται μόνο από τις τεχνολογικές εξελίξεις αυτών των κοινωνιών, αλλά και από τις πολιτικές δομές, τις κοινωνικές πρακτικές, τα οικονομικά συστήματα και την πολιτιστική ατμόσφαιρα. της συγκεκριμένης χρονικής περιόδου. Ενώ οι ερευνητές μελετούν τα αρχαία λατομεία για πολλά χρόνια, μόνο τις τελευταίες δεκαετίες υπήρξε μια σημαντική άνοδος στις συστηματικές έρευνες για αυτό το θέμα. Η εστίαση των μελετητών επικεντρώνεται κυρίως στα λατομεία μαρμάρου και τις μελέτες που στοχεύουν στον εντοπισμό της προέλευσης μαρμάρου που χρησιμοποιούνταν στα αρχαία γλυπτά. Αντίθετα, η εξόρυξη πιο συνηθισμένων δομικών υλικών, όπως διάφορες μορφές εύκαμπτου ασβεστόλιθου, και διάφοροι τύποι  πωρόλιθου, δεν έχει λάβει την δέουσα προσοχή ή αναγνώριση, ιδιαίτερα στις ελληνικές περιοχές και μεταξύ των Ελλήνων μελετητών. Αυτοί οι τύποι ασβεστολιθικών πετρωμάτων έχουν  χρησιμοποιηθεί σε μεγάλα χρονικά διαστήματα κατά την αρχαιότητα στη θεμελίωση κτιρίων αλλά και στην κατασκευή τοιχοποιιών.
Ο λίθος αυτός γνωστός και ως «πώρος», χρησιμοποιήθηκε εκτενώς ως δομικό υλικό, με την λατόμευσή του να είναι ιδιαίτερα διαδεδομένη κατά την κλασική και την ελληνιστική εποχή κάτι το οποίο μαρτυρεί ο τεράστιος αριθμός σημαντικών αρχιτεκτονικών κατασκευών που ανεγέρθηκαν κατά τη διάρκεια αυτής της χρονικής περιόδου. Υπάρχει περιορισμένη έρευνα σχετικά με την καταγραφή και χωροθέτηση των λατομείων πωρόλιθου και ως εκ τούτου είναι σημαντική η διερεύνηση των αρχαίων λατομείων πωρόλιθου που βρέθηκαν σε διάφορες τοποθεσίες στην Ελλάδα.
Σκοπός της παρούσας μελέτης ήταν η συστηματική συγκέντρωσα από βιβλιογραφικά δεδομένα των λατομείων διαχρονικά, της χρήσης των διαφόρων τύπων πωρόλιθου που βρίσκονται διάσπαρτα κατανεμημένοι στον ελλαδικό χώρο καθώς και η χωρική κατανομή τους με τη χρήση των γεωγραφικών συστημάτων πληροφοριών, ένα πολύ χρήσιμο εργαλείο για την οπτικοποίηση και επεξεργασία μεγάλου όγκου χωρικών δεδομένων. Τα αποτελέσματα της χωρικής κατανομής έδειξαν ότι στο νησί της Ρόδου έχει τον μεγαλύτερο καταγεγραμμένο αριθμό λατομείων πωρόλιθου (124 καταγεγραμμένα λατομεία) στο corpus των αρχαίων λατομείων στον ελληνικό χώρο. Ακολουθούν περιοχές στην Κρήτη και στην  Πελοπόνησσο.

description: This is the first paper of a series devoted to studying the population of blue massive stars in NGC 55, a galaxy of the Sculptor group at a distance of about 2 Mpc. We have obtained optical (3300-6210A) low-resolution spectra of blue massive stars with VLT-FORS2, which we have classified with the aid of Milky Way and Magellanic Cloud standard stars. We have developed the first census of massive blue stars in NGC 55. A study of stellar radial velocities shows agreement with existing HI rotational velocity curve work and reveals the presence of one object with peculiar velocity. A qualitative study of the stellar metallicity suggests that its global distribution over NGC 55 is close to that of the LMC, as derived from previous studies. We present a catalogue with 164 classifications of blue massive stars in NGC 55. This catalogue is a first and necessary step for the subsequent quantitative study of blue massive stars in NGC 55 with state-of-the-art models.

Palermo

description: When photography entered the scene in the mid-19th century, the representation of Sicily consisted largely of drawings, paintings, and written accounts that foreign travelers made during the previous century and, even after the diffusion of the new medium, the photographic description of the island was mostly left to them. The continuity of this 'external gaze' motivated the choice of an analysis aiming to explain its influence over the photographic image of Sicilian cities. Using Palermo as a case-study, this article investigates the relationship between the previous visual tradition and the repertories of foreign photographers. Its purpose is to understand how their description of the city evolved between the 19th and the early 20th century, and in what way their choices in subjects, cutting and framing influenced the construction of visual tropes.

description: We present a constructive proof of the Stone-Yosida representation theorem for Riesz spaces motivated by considerations from formal topology. This theorem is used to derive a representation theorem for f-algebras. In turn, this theorem implies the Gelfand representation theorem for C*-algebras of operators on Hilbert spaces as formulated by Bishop and Bridges. Our proof is shorter, clearer, and we avoid the use of approximate eigenvalues.

description: We perform a global QCD analysis of unpolarized parton distributions within a Bayesian Monte Carlo framework, including the new $W$-lepton production data from the STAR Collaboration at RHIC and Drell-Yan di-muon data from the SeaQuest experiment at Fermilab. We assess the impact of these two new measurements on the light antiquark sea in the proton, and the $\bar{d}-\bar{u}$ asymmetry in particular. The SeaQuest data are found to significantly reduce the uncertainty on the $\bar{d}/\bar{u}$ ratio at large parton momentum fractions $x$, strongly favoring an enhanced $\bar{d}$ sea up to $x \approx 0.4$, in general agreement with nonperturbative calculations based on chiral symmetry breaking in QCD.
