description: Περίληψη Εισαγωγή: Παγκοσμίως, 1.5 εκατομμύριο ασθενείς με Χρόνια Νεφρική Νόσο Τελικού Σταδίου, υποβάλλονται σε αιμοκάθαρση. Η θεραπευτική αυτή μέθοδος, εξαιτίας της ιδιαιτερότητας της νόσου, επιφέρει πολλές αλλαγές στην καθημερινότητα των ασθενών αυτών, επηρεάζοντας την ποιότητα ζωής τους. Σκοπός: της παρούσας έρευνας ήταν η διερεύνηση των παραγόντων που σχετίζονται με την αϋπνία σε ασθενείς υποβαλλόμενους σε αιμοκάθαρση. Υλικό και μέθοδος: Το δείγμα της μελέτης αποτέλεσαν 100 ασθενείς που υποβάλλονταν σε αιμοκάθαρση. Η συλλογή δεδομένων πραγματοποιήθηκε με τη συμπλήρωση της «Κλίμακας Αϋπνίας Αθηνών (AIS)» στην οποία συμπεριελήφθησαν τα χαρακτηριστικά των ασθενών. Αποτελέσματα: Από τους 100 συμμετέχοντες, το 77% ήταν άνδρες, το 43% ήταν ηλικίας> 70 ετών και το 66% ήταν συνταξιούχοι. Αναφορικά με τα κλινικά χαρακτηριστικά, στο 44% υπήρχε άλλο νόσημα, το 77% ζυγίζονταν μια φορά εβδομαδιαίως, το 34% βίωνε κόπωση μετά την αιμοκάθαρση. Επιπλέον, το 27% ανέφερε περιορισμό στα ρούχα που φορούσαν, το 47% δήλωσε την επιθυμία να καλύπτει το σημείο της fistula και το 73% βίωνε αλλαγή στην εικόνα σώματος. Σχετικά με την αϋπνία, το 50% των ασθενών είχαν βαθμολογία μικρότερη από 6 στην κλίμακα της αϋπνίας (διάμεσος), ενώ το 25% μικρότερη από 4. Οι τιμές αυτές σε σχέση με το πιθανό εύρος της βαθμολογίας υποδηλώνουν χαμηλά επίπεδα αϋπνίας των ασθενών. Στατιστικώς σημαντικά μεγαλύτερη βαθμολογία στην κλίμακα είχαν οι ασθενείς ηλικίας άνω των 60 ετών (p=0.002), oι ασθενείς που είχαν και άλλο νόσημα (p=0.001), αυτοί που βίωναν κόπωση μετά την αιμοκάθαρση (p=0.001), αυτοί που βίωναν συνεχή κόπωση ( p=0.001), αυτοί που έχουν αλλαγή στην εικόνα σώματος (p=0.003) και αυτοί που ένιωθαν περιορισμό στα ρούχα που μπορούσαν να φορέσουν (p=0.001). Συμπεράσματα: Από τα αποτελέσματα αυτής της μελέτης προκύπτει ότι οι ασθενείς προχωρημένης ηλικίας, oι ασθενείς με συν νοσηρότητα, αυτοί που βίωναν κόπωση μετά την αιμοκάθαρση, αυτοί που πίστευαν ότι είχαν αλλαγή στην εικόνα σώματος, αυτοί που ένιωθαν συχνά κνησμό και αυτοί που ένιωθαν περιορισμό στα ρούχα που μπορούσαν να φορέσουν, ταλαιπωρούνται από υψηλότερα ποσοστά αϋπνίας. Η αποτελεσματική παρέμβαση στους ασθενείς υποβαλλόμενους σε αιμοκάθαρση με αϋπνία απαιτεί ολιστική προσέγγιση. Λέξεις - κλειδιά: Αιμοκάθαρση, αϋπνία, διαταραχές ύπνου

description: Abstract

Lytic Polysaccharide Monooxygenases (LPMOs) and chitinases constitute pivotal chitinolytic enzymatic components in Bacillus cereus, exerting significant influence on the degradation of chitin. This investigation used bioinformatics tools to endeavor the evolution and action mechanisms of enzymes (chitinases and BcLPMO10B) influencing chitin and cellulose degradation in B. cereus, employing computational methods for phylogenetic analysis, 3D structure modeling, validation, and molecular dynamics simulations (MDS), offering insights into their potential applications in biofuels, medicine, and agriculture. Phylogenetic analysis of chitinases and BcLPMO10B exhibit strong associations with other bacteria, indicating a potential history of shared genetic material over time. To achieve the objective of analyzing action mechanism, the homology modeling technique was employed to construct three-dimensional structures of BcLPMO10B and chitinases using SwissModel, I-TASSER, and ROBETTA Baker Laboratory. Following the comparative validation of predicted structures utilizing various servers, 3D structures generated by the Swiss Model were chosen for subsequent computational analysis. Subsequently, docking studies elucidated the functional significance of target proteins; through the prediction of ligand binding modes. The research also explored the dynamic behaviors of BcLPMO10B and chitinases by MDS. AutoDock Vina revealed robust binding affinities and unveiled key interacting amino acids of chitinases with N-acetyl-D(+)-glucosamine (GLcNAc) and BcLPMO10B with 2,6-dimethoxyphenol. Furthermore, MDS validated the stability of these complexes by assessing the temporal motion of individual atoms within these complexes, employing Root Mean Square Deviation (RMSD) analysis, recording low RMSF values, and evaluating the extent of hydrogen bonding interactions. The implications of these complexes extend the enzymatic efficiencies, functionalities and substrate binding affinities. In sum, this computational analysis augments our comprehension of these enzymes and highlights their potential applications in biotechnology and pharmaceutical research.

description: In this research, we compare malware detection techniques based on static, dynamic, and hybrid analysis. Specifically, we train Hidden Markov Models (HMMs ) on both static and dynamic feature sets and compare the resulting detection rates over a substantial number of malware families. We also consider hybrid cases, where dynamic analysis is used in the training phase, with static techniques used in the detection phase, and vice versa. In our experiments, a fully dynamic approach generally yields the best detection rates. We discuss the implications of this research for malware detection based on hybrid techniques.

description: We construct models with minimal field content that can simultaneously explain the muon g-2 anomaly and give the correct dark matter relic abundance. These models fall into two general classes, whether or not the new fields couple to the Higgs. For the general structure of models without new Higgs couplings, we provide analytical expressions that only depend on the $SU(2)_L$ representation. These results allow to demonstrate that only few models in this class can simultaneously explain $(g-2)_μ$ and account for the relic abundance. The experimental constraints and perturbativity considerations exclude all such models, apart from a few fine-tuned regions in the parameter space, with new states in the few 100 GeV range. In the models with new Higgs couplings, the new states can be parametrically heavier by a factor $\sqrt{1/y_μ}$, with $y_μ$ the muon Yukawa coupling, resulting in masses for the new states in the TeV regime. At present these models are not well constrained experimentally, which we illustrate on two representative examples.

description: We define a (chaotic) deterministic variant of random multiplicative cascade models of turbulence. It preserves the hierarchical tree structure, thanks to the addition of infinitesimal noise. The zero-noise limit can be handled by Perron-Frobenius theory, just as the zero-diffusivity limit for the fast dynamo problem. Random multiplicative models do not possess Kolmogorov 1941 (K41) scaling because of a large-deviations effect. Our numerical studies indicate that deterministic multiplicative models can be chaotic and still have exact K41 scaling. A mechanism is suggested for avoiding large deviations, which is present in maps with a neutrally unstable fixed point.

description: Jellyfish are cluster galaxies that experience strong ram-pressure effects that strip their gas. Their H$α$ images reveal ionized gas tails up to 100 kpc, which could be hosting ongoing star formation. Here we report the ultraviolet (UV) imaging observation of the jellyfish galaxy JO201 obtained at a spatial resolution $\sim$ 1.3 kpc. The intense burst of star formation happening in the tentacles is the focus of the present study. JO201 is the "UV-brightest cluster galaxy" in Abell 85 ($z \sim$ 0.056) with knots and streams of star formation in the ultraviolet. We identify star forming knots both in the stripped gas and in the galaxy disk and compare the UV features with the ones traced by H$α$ emission. Overall, the two emissions remarkably correlate, both in the main body and along the tentacles. Similarly, also the star formation rates of individual knots derived from the extinction-corrected FUV emission agree with those derived from the H$α$ emission and range from $\sim$ 0.01 -to- 2.07 $M_{\odot} \, yr^{-1}$. The integrated star formation rate from FUV flux is $\sim$ 15 $M_{\odot} \, yr^{-1}$. The unprecedented deep UV imaging study of the jellyfish galaxy JO201 shows clear signs of extraplanar star-formation activity due to a recent/ongoing gas stripping event.

description: Azimuthal angle two particle correlations have been shown to be a powerful probe for extracting novel features of jet induced correlations produced in Au+Au collisions at RHIC. At intermediate $p_T$, 2-5GeV/c, the jets have been shown to be significantly modified in both their particle composition and their angular distribution compared to p+p collisions. Two-particle angular correlations with identified particles provide sensitive probes of both the interactions between hard scattered partons and the medium. The systematics of these correlations are essential to understanding the physics of intermediate $p_T$ in heavy ion collisions.

description: We compare our analysis of the Baryon Acoustic Oscillations (BAO) feature in the correlation functions of SDSS BOSS DR12 LOWZ and CMASS galaxy samples with the findings of arXiv:1509.06371v2. Using subsets of the data we obtain an empirical estimate of the errors on the correlation functions which are in agreement with the simulated errors of arXiv:1509.06371v2. We find that the significance of BAO detection is the quantity most sensitive to the choice of the fitting range with the CMASS value decreasing from $8.0σ$ to $5.3σ$ as the fitting range is reduced. Although our measurements of $D_V(z)$ are in agreement with those of arXiv:1509.06371v2, we note that their CMASS $8.0σ$ (LOWZ $4.0σ$) detection significance reduces to $4.7σ$ ($2.8σ$) in fits with their diagonal covariance terms only. We extend our BAO analysis to higher redshifts by fitting to the weighted mean of 2QDESp, SDSS DR5 UNIFORM, 2QZ and 2SLAQ quasar correlation functions, obtaining a $7.6\%$ measurement compared to $3.9\%$ achieved by eBOSS DR14. Unlike for the LRG surveys, the larger error on quasar correlation functions implies a smaller role for nuisance parameters (accounting for scale-dependent clustering) in providing a good fit to the fiducial $Λ$CDM model. Again using only the error bars of arXiv:1705.06373v2 and ignoring any off-diagonal covariance matrix terms, we find that the eBOSS peak significance reduces from 2.8 to $1.4σ$. We conclude that for both LRGs and quasars, the reported BAO peak significances from the SDSS surveys depend sensitively on the accuracy of the covariance matrix at large separations.

description: 2MASX J04035024-0239275 is a bright red elliptical galaxy at redshift 0.0661 that presents two extended sources at 2\arcsec~to the north-east and 1\arcsec~to the south-west. The sizes and surface brightnesses of the two blue sources are consistent with a gravitationally-lensed background galaxy. In this paper we present MUSE observations of this galaxy from the All-weather MUse Supernova Integral-field Nearby Galaxies (AMUSING) survey, and report the discovery of a background lensed galaxy at redshift 0.1915, together with other 15 background galaxies at redshifts ranging from 0.09 to 0.9, that are not multiply imaged. We have extracted aperture spectra of the lens and all the sources and fit the stellar continuum with STARLIGHT to estimate their stellar and emission line properties. A trace of past merger and active nucleus activity is found in the lensing galaxy, while the background lensed galaxy is found to be star-forming. Modeling the lensing potential with a singular isothermal ellipsoid, we find an Einstein radius of 1\farcs45$\pm$0\farcs04, which corresponds to 1.9 kpc at the redshift of the lens and it is much smaller than its effective radius ($r_{\rm eff}\sim$ 9\arcsec). Comparing the Einstein mass and the STARLIGHT stellar mass within the same aperture yields a dark matter fraction of $18 \% \pm 8$ \% within the Einstein radius. The advent of large surveys such as the Large Synoptic Survey Telescope (LSST) will discover a number of strong-lensed systems, and here we demonstrate how wide-field integral field spectroscopy offers an excellent approach to study them and to precisely model lensing effects.

description: The integrability of $R^2$-gravity with torsion in two dimensions is traced to an ultralocal dynamical symmetry of constraints and momenta in Hamiltonian phase space. It may be interpreted as a quadratically deformed $iso(2,1)$-algebra with the deformation consisting of the Casimir operators of the undeformed algebra. The locally conserved quantity encountered in the explicit solution is identified as an element of the centre of this algebra. Specific contractions of the algebra are related to specific limits of the explicit solutions of this model.

description: Universal quantum computation using photonic systems requires gates whose Hamiltonians are of order greater than quadratic in the quadrature operators. We first review previous proposals to implement such gates, where specific non-Gaussian states are used as resources in conjunction with entangling gates such as the continuous-variable versions of C-PHASE and C-NOT gates. We then propose ON states which are superpositions of the vacuum and the $N^{th}$ Fock state, for use as non-Gaussian resource states. We show that ON states can be used to implement the cubic and higher-order quadrature phase gates to first order in gate strength. There are several advantages to this method such as reduced number of superpositions in the resource state preparation and greater control over the final gate. We also introduce useful figures of merit to characterize gate performance. Utilising a supply of on-demand resource states one can potentially scale up implementation to greater accuracy, by repeated application of the basic circuit.

description: A dynamical theory which accounts for all microscopic one-electron processes is used to study the spectral function of the 1D Hubbard model for the whole $(k, ω)$-plane, beyond previous studies which focused on the weight distribution in the vicinity of the singular branch lines only. While our predictions agree with those of the latter studies concerning the tetracyanoquinodimethane (TCNQ) related singular features in photoemission of the organic compound tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ) metallic phase, the generalized theory also leads to quantitative agreement concerning the tetrathiafulvalene (TTF) related finite-energy spectral features, which are found to correspond to a value of the on-site repulsion $U$ larger than for TCNQ. Our study reveals the microscopic mechanisms behind the unusual spectral features of TTF-TCNQ and provides a good overall description of those features for the whole $(k, ω)$-plane.

description: Modular invariant conformal field theories with just one primary field and central charge $c=24$ are considered. It has been shown previously that if the chiral algebra of such a theory contains spin-1 currents, it is either the Leech lattice CFT, or it contains a Kac-Moody sub-algebra with total central charge 24. In this paper all meromorphic modular invariant combinations of the allowed Kac-Moody combinations are obtained. The result suggests the existence of 71 meromorphic $c=24$ theories, including the 41 that were already known.

description: The effects of lattice distortion and chemical disorder on charge transport properties of two-terminal zigzag phosphorene nanoribbons (zPNRs), which shows resonant tunneling behavior under an electrical applied bias, are studied. Our comprehensive study is based on an {\it ab~initio} quantum transport calculations on the basis of the Landauer theory. We use nitrogen and silicon substitutional dopant atoms, and employ different physical quantities such as $I-V$ curve, voltage drop behavior, transmission spectrum, transmission pathway, and atomic current, to explore the transport mechanism of zPNR devices under a bias voltage. The calculated transmission pathways show the transition from a ballistic transport regime to a diffusive and in some particular cases to localized transport regimes. Current flowing via the chemical bonds and hopping are monitored, however, the conductance originates mainly from a charge traveling through the chemical bonds in the vicinity of the zigzag edges. Our results show that, in the doped systems, the device conductance decreases and negative differential resistance characteristic becomes weak or eliminates. Besides, the conductance in a pure zPNR system is almost independent of the ribbon width.

description: I show that the effective action of string compactifications has a structure that can naturally solve the supersymmetric flavour and CP problems. At leading order in the g_s and α' expansions, the hidden sector factorises. The moduli space splits into two mirror parts that depend on Kahler and complex structure moduli. Holomorphy implies the flavour structure of the Yukawa couplings arises in only one part. In type IIA string theory flavour arises through the Kahler moduli sector and in type IIB flavour arises through the complex structure moduli sector. This factorisation gives a simple solution to the supersymmetric flavour and CP problems: flavour physics is generated in one sector while supersymmetry is broken in the mirror sector. This mechanism does not require the presence of gauge, gaugino or anomaly mediation and is explicitly realised by phenomenological models of IIB flux compactifications.

Upstream Shear Layer Stabilisation via Self-Oscillating Trailing Edge Flaplets

Year: 2018

description: The flow around a symmetric aerofoil (NACA 0012) with an array of flexible flaplets attached to the trailing edge has been investigated at Reynolds numbers of 100,000 - 150,000 by using High-Speed Time-Resolved Particle Image Velocimetry (HS TR-PIV) and motion tracking of the flaplets' tips. Particular attention has been made on the upstream effect on the boundary layer evolution along the suction side of the wing, at angles of attack of 0$^\text{o}$ and 10$^\text{o}$. For the plain aerofoil, without flaplets, the boundary layer on the second half of the aerofoil shows the formation of rollers as the shear-layer rolls-up in the fundamental instability mode (linear state). Proper Orthogonal Decomposition (POD) analysis shows that non-linear modes are also present, the most dominant being the pairing of successive rollers. When the flaplets are attached, it is shown that the flow-induced oscillations of the flaplets are able to create a lock-in effect that stabilises the linear state of the shear layer, whilst delaying or damping the growth of non-linear modes. It is hypothesised that the modified trailing edge is beneficial for reducing drag and can reduce aeroacoustic noise production in the lower frequency band, as indicated by an initial acoustic investigation.

description: We calculate the radiative capture cross section for $^7$Be($α, γ$)$^{11}$C and its reaction rate of relevance for the big bang nucleosynthesis. The impact of this reaction on the primordial $^7$Li abundance is revised including narrow and broad resonances in the pertinent energy region. Our calculations show that it is unlikely that very low energy resonances in $^{11}$C of relevance for the big bang nucleosynthesis would emerge within a two-body potential model. Based on our results and a comparison with previous theoretical and experimental analyses, we conclude that the impact of this reaction on the so-called "cosmological lithium puzzle" is completely irrelevant.

description: Scattering by a single impurity introduced in a strongly correlated electronic system is studied by exact diagonalization of small clusters. It is shown that an inert site which is spinless and unable to accomodate holes can give rise to strong resonant scattering. A calculation of the local density of state reveals that, for increasing antiferromagnetic exchange coupling, d, s and p-wave symmetry bound states in which a mobile hole is trapped by the impurity potential induced by a local distortion of the antiferromagnetic background successively pull out from the continuum.

description: Recent studies have indicated that the HCN-to-CO(J=1-0) and HCO+-to-HCN(J=1-0) ratios are significantly different between galaxies with AGN (active galactic nucleus) and SB (starburst) signatures. In order to study the molecular gas properties in active galaxies and search for differences between AGN and SB environments, we observed the HCN(J=1-0), (J=2-1), (J=3-2), HCO+(J=1-0) and HCO+(J=3-2), emission with the IRAM 30m in the centre of 12 nearby active galaxies which either exhibit nuclear SB and/or AGN signatures. Consistent with previous results, we find a significant difference of the HCN(J=2-1)-to-HCN(J=1-0), HCN(J=3-2)-to-HCN(J=1-0), HCO+(J=3-2)-to-HCO+(J=3-2), and HCO+-to-HCN intensity ratios between the sources dominated by an AGN and those with an additional or pure central SB: the HCN, HCO+ and HCO+-to-HCN intensity ratios tend to be higher in the galaxies of our sample with a central SB as opposed to the pure AGN cases which show rather low intensity ratios. Based on an LVG analysis of these data, i.e., assuming purely collisional excitation, the (average) molecular gas densities in the SB dominated sources of our sample seem to be systematically higher than in the AGN sources. The LVG analysis seems to further support systematically higher HCN and/or lower HCO+ abundances as well as similar or higher gas temperatures in AGN compared to the SB sources of our sample. Also, we find that the HCN-to-CO ratios decrease with increasing rotational number J for the AGN while they stay mostly constant for the SB sources.

description: A structured methodology designed to evaluate, categorize, and refine truth through iterative reasoning. Unlike traditional AI models that rely solely on data retrieval, this framework integrates logical processing to distinguish between known truths (T_k), theories (T_th), and fiction (T_f) while recognizing unresolved inquiries (Q). We applied this system to multiple real-world and historical claims, assessing its strengths, weaknesses, and potential applications

description: Despite tremendous progress of quantum computation with superconducting qubits, up-scaling for practical applications is hindered by decoherence and fluctuations induced by material defects. In this work, a qubit interface has been developed to study the microscopic nature of individual defects in a probe material. Further, a portable method has been developed to find locations of individual defects in ready-made qubit samples, which offers to test and improve micro-fabrication of qubits.

description: We propose a method to subtract a photon from a double sideband mode of continuous-wave light. The central idea is to use phase modulation as a frequency sideband beamsplitter in the heralding photon subtraction scheme, where a small portion of the sideband mode is downconverted to the carrier frequency to provide a trigger photon. An optical Schrödinger's cat state is created by applying the propesed method to a squeezed state at 500MHz sideband, which is generated by an optical parametric oscillator. The Wigner function of the cat state reconstructed from a direct homodyne measurement of the 500MHz sideband modes shows the negativity of $W(0,0) = -0.088\pm0.001$ without any loss corrections.

description: In the process of translating a certain source into another language, the translator has the opportunity to change the text, as well as use other equivalents of expressions. But in any case, giving from genuine content is not allowed. It should be said that thanks to translators, representatives of many peoples, reading works, studying the literature of other peoples, have the opportunity to get to know each other closer. Writers in their works seek to express the history of the country, customs of the people, lifestyle, culture and wealth of language. Consequently, we will be right, calling translators who occupy an important place in the cultural interchange of peoples, selfless people. On a par with such people we see H. Ismaili.
Flavour Conservation in Two Higgs Doublet Models

description: In extensions of the Standard Model with two Higgs doublets, flavour changing Yukawa couplings of the neutral scalars may be present at tree level. In this work we consider the most general scenario in which those flavour changing couplings are absent. We re-analyse the conditions that the Yukawa coupling matrices must obey for such \emph{general flavour conservation} (gFC), and study the one loop renormalisation group evolution of such conditions in both the quark and lepton sectors. We show that gFC in the leptonic sector is one loop stable under the Renormalization Group Evolution (RGE) and in the quark sector we present some new Cabibbo like solution also one loop RGE stable. At a phenomenological level, we obtain the regions for the different gFC parameters that are allowed by the existing experimental constraints related to the 125 GeV Higgs.

description: The identification of point sources poses a great challenge for the high energy community. We present a new approach to evaluate the likelihood of a set of sources being a Galactic population based on the simple assumption that galaxies similar to the Milky Way host comparable populations of gamma-ray emitters. We propose a luminosity constraint on Galactic source populations which complements existing approaches by constraining the abundance and spatial distribution of any objects of Galactic origin, rather than focusing on the properties of a specific candidate emitter. We use M31 as a proxy for the Milky Way, and demonstrate this technique by applying it to the unidentified EGRET sources. We find that it is highly improbable that the majority of the unidentified EGRET sources are members of a Galactic halo population (e.g., dark matter subhalos), but that current observations do not provide any constraints on all of these sources being Galactic objects if they reside entirely in the disk and bulge. Applying this method to upcoming observations by the Fermi Gamma-ray Space Telescope has the potential to exclude association of an even larger number of unidentified sources with any Galactic source class.

description: The anomalous exponent, $η_{p}$, for the decay of the reunion probability of $p$ vicious walkers, each of length $N$, in $d$ $(=2-ε)$ dimensions, is shown to come from the multiplicative renormalization constant of a $p$ directed polymer partition function. Using renormalization group(RG) we evaluate $η_{p}$ to $O(ε^2)$. The survival probability exponent is $η_{p}/2$. For $p=2$, our RG is exact and $η_p$ stops at $O(ε)$. For $d=2$, the log corrections are also determined. The number of walkers that are sure to reunite is 2 and has no $ε$ expansion.

Vortex core ordering in Abrikosov lattices

description: Vortex lattices, arising from repulsive inter-vortex interactions, are a canonical example of emergent phenomena. Recent studies on the cuprates have drawn attention to the appearance of competing correlations within vortex cores. This gives internal structure to each vortex and changes the nature of inter-vortex interactions, especially at short range. This can have significant consequences for vortex lattices wherein vortices are in close proximity to one another. We consider the attractive Hubbard model, a prototypical model for phase competition, with checkerboard charge density wave order appearing in vortex cores. We use next-nearest-neighbour hopping, $t'$, to tune the strength of competing order in the core. Using Bogoliubov deGennes mean field simulations, we study the variation in quasiparticle gap, superfluid stiffness and shear stiffness, as the core order is tuned. The presence of competing order allows for a new defect: domain walls that separate regions with different types of charge order overlying the vortex-laden superfluid background. We find the energy cost of such domain walls. Our results indicate a stable intermediate supersolid region with coexisting superfluid and charge orders. At one end, this phase is unstable to melting of the vortex lattice into a purely charge ordered state, possibly via an intervening liquid-like state. At the other end, charge order becomes incoherent due to domain formation while superconducting order persists.
