description: The problem of spin-charge separation is analyzed numerically in the metallic phase of the one-band Hubbard model in one dimension by studying the behavior of the single-particle Green's function and of the spin and charge susceptibilities. We first analyze the Quantum-Monte Carlo data for the imaginary-time Green's function within the Maximum Entropy method in order to obtain the spectral function at real frequencies. For some values of the momentum sufficiently away from the Fermi surface two separate peaks are found, which can be identified as charge and spin excitations. In order to improve our accuracy and to be able to extend our study to a larger portion of the Brillouin zone, we also fit our data with the imaginary-time Green's function obtained from the Luttinger-model solution with two different velocities as fitting parameters. The excitation energies associated with these velocities turn out to agree, in a broad range of momenta, with the ones calculated from the charge and spin susceptibilities. This allows us to identify these single-particle excitations as due to a separation of spin and charge. Remarkably, the range of momenta where spin-charge separation is seen extends well beyond the region of linear dispersion about the Fermi surface. We finally discuss a possible extension of our method to detect spin-charge separation numerically in two dimensions.

description: Distribution of loops in a one-dimensional random walk (RW), or, equivalently, neutral segments in a sequence of positive and negative charges is important for understanding the low energy states of randomly charged polymers. We investigate numerically and analytically loops in several types of RWs, including RWs with continuous step-length distribution. We show that for long walks the probability density of the longest loop becomes independent of the details of the walks and definition of the loops. We investigate crossovers and convergence of probability densities to the limiting behavior, and obtain some of the analytical properties of the universal probability density.

description: We present a unified account of damping of low-lying collective modes and of relaxation of temperature anisotropies in a trapped Bose gas in the collisionless regime. By means of variational techniques, we show that the relaxation times for the two situations are closely related to the simplest variational estimate of the viscous relaxation time. We derive rather precise theoretical expressions for the characteristic relaxation times, and compare our results with experiment.

On a General Class of Wormhole Geometries

Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

subject: FOS: Physical sciences

description: A general class of solutions is obtained which describe a spherically symmetric wormhole system. The presence of arbitrary functions allows one to describe infinitely many wormhole systems of this type. The source of the stress-energy supporting the structure consists of an anisotropic brown dwarf ``star'' which smoothly joins the vacuum and may possess an arbitrary cosmological constant. It is demonstrated how this set of solutions allows for a non-zero energy density and therefore allows positive stellar mass as well as how violations of energy conditions may be minimized. Unlike examples considered thus far, emphasis here is placed on construction by manipulating the matter field as opposed to the metric. This scheme is generally more physical than the purely geometric method. Finally, explicit examples are constructed including an example which demonstrates how multiple closed universes may be connected by such wormholes. The number of connected universes may be finite or infinite.

description: The formalism of (${\vec γ},{\vec N}N$) reactions is given where the incident photon is polarized and the outgoing nucleon polarization is detected. Sixteen structure functions and fifteen polarization observables are found in the general case, while only eight structure functions and seven polarizations observables survive in coplanar kinematics. Numerical examples are presented for the $^{16}$O($γ,pn$) and $^{16}$O($γ,pp$) reactions. The transitions to the ground state of $^{14}$C and $^{14}$N are calculated in a model where realistic short-range and tensor correlations are taken into account for the $pn$ pair, while short-range and long-range correlations are included in a consistent way for $pp$ pairs. The effects of the one-body and two-body components of the nuclear current and the role of correlations in cross sections and polarizations are studied and discussed.

description: Purpose: This work proposes an in-silico screening method for identifying promising formulation candidates in complex lipid-based drug delivery systems (LBDDS). Method: The approach is based on a minimum amount of experimental data for API solubilites in single excipients. Intermolecular interactions between APIs and excipients as well as between different excipients were accounted for by the Perturbed-Chain Statistical Associating Fluid Theory. The approach was applied to the in-silico screening of lipid-based formulations for ten model APIs (fenofibrate, ibuprofen, praziquantel, carbamazepine, cinnarizine, felodipine, naproxen, indomethacin, griseofulvin and glibenclamide) in mixtures of up to three out of nine excipients (tricaprylin, Capmul MCM, caprylic acid, Capryol™ 90, Lauroglycol™ FCC, Kolliphor TPGS, polyethylene glycol, carbitol and ethanol). Results: For eight out of the ten investigated model APIs, the solubilities in the final formulations could be enhanced by up to 100 times compared to the solubility in pure tricaprylin. Fenofibrate, ibuprofen, praziquantel, carbamazepine are recommended as type I formulations, whereas cinnarizine and felodipine showed a distinctive solubility gain in type II formulations. Increased solubility was found for naproxen and indomethacin in type IIIb and type IV formulations. The solubility of griseofulvin and glibenclamide could be slightly enhanced in type IIIb formulations. The experimental validation agreed very well with the screening results. Conclusion: The API solubility individually depends on the choice of excipients. The proposed in-silico-screening approach allows formulators to quickly determine most-appropriate types of lipid-based formulations for a given API with low experimental effort.

description: The Home away from Home ERASMUS+ project has been developed within a context of increasing levels of migration in Europe. Some of this migration is occurring into areas with a long experience of migration, whereas in other areas it is a new phenomenon. Though this tends to mean that there are different perspectives on the issue in different contexts, generally speaking migration is the subject of debate and political and social concern across the European Union. Nevertheless, there is considerably lack of knowledge and awareness about the topic. As the Special Eurobarometer report showed in 2018 (Survey 469 related to the integration of immigrants)1 , most European citizens are not aware of the actual facts and figures on migration, with only 37% being well informed about immigration and integration. At the same time, according to this report, negative perceptions of the impact immigrants have on society are more likely amongst those who do not feel well informed about immigration and integration issues and also amongst those who have little interaction with immigrants (p.82). This is the context, in which the Home away from Home project was designed with the aim of supporting the integration of refugees, asylum seekers and migrants. Though the construct of integration is a contested one, for Home away from Home it relates to the successful co-existence of two or more cultures within one society, which requires change and re-education for all in order to address negative attitudes towards increasing diversity, rather than responsibility for integration residing completely in the migrant communities, which suggests a more assimilationist process. This necessity to consider carefully and critically the language and discourse that surrounds issues of migration is a thread, which has run throughout the project and will be seen in this report on the research undertaken as part of the project. However, the diversity of background experiences, histories, and languages brought together by this project has proven to be a rich source of learning and reflection, enhanced by the opportunities grasped to see the world through different sets of eyes.
Agent-Based Recovery Model for Seismic Resilience Evaluation of Electrified Communities

description: In this paper, an agent-based framework to quantify the seismic resilience of an Electric Power Supply System (EPSS) and the community it serves is presented. Within the framework, the loss and restoration of the EPSS power generation and delivery capacity and of the power demand from the served community are used to assess the electric power deficit during the damage absorption and recovery processes. Damage to the components of the EPSS and of the community built environment is evaluated using the seismic fragility functions. The restoration of the community electric power demand is evaluated using the seismic recovery functions. However, the post-earthquake EPSS recovery process is modeled using an agent-based model with two agents, the EPSS Operator and the Community Administrator. The resilience of the EPSS-Community system is quantified using direct, EPSS-related, and societal, community-related, indicators. Parametric studies are carried out to quantify the influence of different seismic hazard scenarios, agent characteristics, and power dispatch strategies on the EPSS-Community seismic resilience. The use of the agent-based modeling framework enabled a rational formulation of the post-earthquake recovery phase and highlighted the interaction between the EPSS and the community in the recovery process not quantified in resilience models developed to date. Furthermore, it shows that the resilience of different community sectors can be enhanced by different power dispatch strategies. The proposed agent-based EPSS-Community system resilience quantification framework can be used to develop better community and infrastructure system risk governance policies.

Development of an electronic paper prototype on bacterial cellulose using electrochromic systems

Electronic paper

description: Various techniques were explored to develop an electronic paper prototype on bacterial cellulose. Electrochromic systems were used to demonstrate the proof of concept of a dynamic display on cellulose. Bacterial cellulose was synthesized in a culture of NQ-5 strain of Acetobacter xylinum in the standard glucose-rich (SH) medium. Bacterial cellulose thus formed was dimensionally stable, had a paper-like appearance and had a unique microfibrillar nanostructure. This bacterial cellulose was made an electrically conducting (or semi-conducting) sheet by deposition of conductors around the microfibrils to provide conducting pathways and then immobilizing electrochromic dyes into the microstructure. The whole system was then cased between transparent electrodes in three different device structures. Upon application of switching potentials (2-6V); a reversible color change was demonstrated down to a standard pixel sized area (~100μm²). The major advantages of such a prototype are its high paper-like reflectivity, flexibility, contrast, biodegradability, low power consumption etc. among many more. Ways to integrate these prototypes to full scale displays were explored. Potential future applications of this concept are E-book tablets, E-newspapers, dynamic wall papers, rewritable maps and learning tools

description: A method of modelling the three-dimensional microstructure of random isotropic two-phase materials is proposed. The information required to implement the technique can be obtained from two-dimensional images of the microstructure. The reconstructed models share two-point correlation and chord-distribution functions with the original composite. The method is designed to produce models for computationally and theoretically predicting the effective macroscopic properties of random materials (such as electrical and thermal conductivity, permeability and elastic moduli). To test the method we reconstruct the morphology and predict the conductivity of the well known overlapping sphere model. The results are in very good agreement with data for the original model.

description: We study the motion of a self-attractive Bose-Einstein condensate with pseudo-spin 1/2 driven by a synthetic Rabi (Zeeman-like) field. This field triggers the pseudo-spin dynamics resulting in a density redistribution between its components and, as a consequence, in changes of the overall density distribution. In the presence of an additional external potential, the latter produces a net force acting on the condensate and activates its displacement. As an example, here we consider the case of a one-dimensional condensate in a random potential.

There are in fact physically reasonable equations of state for which the number of necks can be arbitrarily large. The proofs of these statements rely on a recent regularized formulation of the field equations for static spherically symmetric models due to Nilsson and Uggla. We discuss in particular the equation of state p=ρ-ρ_s which plays a central role in this context.

description: The presence of lake on Saturn’s Titan depicts possibility of water or a solvent resembling to it. And since there is liquid, there could be a possibility of biochemical dynamics too........ it could also be in a primordial state, not resembling to what we have observed on Earth during the course of evolution. Once scientific world starts finding out life forms, beyond the typical framework of life exist on Earth, we may encounter one in remote planets too. With the presence of lake on Titan, such a prospect cannot be ruled out. ……. and why life only? Existence of lake also points out the likelihood of some geographical catastrophe on the surface of Titan. This would open vistas for scientists to learn the limnological as well as physicochemical dynamics of extremely cold planets. This will also unravel the path of evolution of Saturn, whether things are heading towards radiance, convergence or have no definite trajectory.

description: The lifetime of image states, which represent a key quantity to probe the coupling of surface electronic states with the solid substrate, have been recently determined for quantum numbers $n\le 6$ on Cu(100) by using time-resolved two-photon photoemission in combination with the coherent excitation of several states (U. Höfer et al, Science 277, 1480 (1997)). We here report theoretical investigations of the lifetime of image states on copper surfaces. We evaluate the lifetimes from the knowledge of the self-energy of the excited quasiparticle, which we compute within the GW approximation of many-body theory. Single-particle wave functions are obtained by solving the Schrödinger equation with a realistic one-dimensional model potential, and the screened interaction is evaluated in the random-phase approximation (RPA). Our results are in good agreement with the experimentally determined decay times.

It is proved that if $|γ_{\infty}(C_{G}(a))|\leq m$ for any $a\in A^{\#}$, then the order of $γ_{\infty}(G)$ is $m$-bounded. If $F(C_{G}(a))$ has index at most $m$ in $C_G(a)$ for any $a \in A^{\#}$, then the index of $F_2(G)$ is $m$-bounded.

description: The effect of a microscopic three-body force on the saturation properties of nuclear matter is studied within the Brueckner-Hartree-Fock approach. The calculations show a decisive improvement of the saturation density along with an overall agreement with the empirical saturation point. With the three-body force the symmetry energy turns more rapidly increasing with density, which allows for the direct URCA process to occur in $β$-stable neutron star matter. The influence of the three-body force on the nuclear mean field does not diminish the role of the ground state correlations.

description: Quantum tunneling of domain walls out of an impurity potential in a mesoscopic ferromagnetic sample is investigated. Using improved expressions for the domain wall mass and for the pinning potential, we find that the cross-over temperature between thermal activation and quantum tunneling is of a different functional form than found previously. In materials like Ni or YIG, the crossover temperatures are around 5 mK. We also find that the WKB exponent is typically two orders of magnitude larger than current estimates. The sources for these discrepancies are discussed, and precise estimates for the transition from three-dimensional to one-dimensional magnetic behavior of a wire are given. The cross-over temperatures from thermal to quantum transitions and tunneling rates are calculated for various materials and sample sizes.

description: For a twisted (vortex) Dirac particle in nonuniform electric and magnetic fields, the relativistic Foldy-Wouthuysen Hamiltonian is derived including high order terms describing new effects. The result obtained shows for the first time that a twisted spin-1/2 particle possesses a tensor magnetic polarizability and a measurable (spectroscopic) electric quadrupole moment. We have calculated the former parameter and have evaluated the latter one for a twisted electron. The tensor magnetic polarizability of the twisted electron can be measured in a magnetic storage ring because a beam with an initial orbital tensor polarization acquires a horizontal orbital vector polarization. The electric quadrupole moment is rather large and strongly influences the dynamics of the intrinsic orbital angular momentum. Three different methods of its measurements, freezing the intrinsic orbital angular momentum and two resonance methods, are proposed. The existence of the quadrupole moment of twisted electrons can lead to practical applications.

description: The classical XXZ triangular-lattice antiferromagnet (TAF) shows both an Ising and a BKT transition, related to the chirality and the in-plane spin components, respectively. In this paper the quantum effects on the thermodynamic quantities are evaluated by means of the pure-quantum self-consistent harmonic approximation (PQSCHA), that allows one to deal with any spin value through classical MC simulations. We report the internal energy, the specific heat, and the in-plane correlation length of the quantum XX0 TAF, for S=1/2, 1, 5/2. The quantum transition temperatures turn out to be smaller the smaller the spin, and agree with the few available theoretical and numerical estimates.

description: The quantization of the most general Bianchi Type II geometry -with all six scale factors, as well as the lapse function and the shift vector, present- is considered. In an earlier work, a first reduction of the initial 6-dimensional configuration space, to a 4-dimensional one, has been achieved by the usage of the information furnished by the quantum form of the linear constraints. Further reduction of the space in which the wave function -obeying the Wheeler-DeWitt equation- lives, is accomplished by unrevealling the extra symmetries of the Hamiltonian. These symmetries appear in the form of -linear in momenta- first integrals of motion. Most of these symmetries, correspond to G.C.T.s through the action of the automorphism group. Thus, a G.C.T. invariant wave function is found, which depends on the only true degree of freedom, i.e. the unique curvature invariant, characterizing the hypersurfaces t=const.

description: The electronic response of a composite consisting of aligned metallic cylinders in vacuum is investigated, on the basis of photonic band structure calculations. The effective long-wavelength dielectric response function is computed, as a function of the filling fraction. A spectral representation of the effective response is considered, and the surface mode strengths and positions are analyzed. The range of validity of a Maxwell-Garnett-like approach is discussed, and the impact of our results on absorption spectra and electron energy-loss phenomena is addressed.

title: Mindfulness, Chronic Pelvic Pain & Chronic Postoperative Pain
Creators: name: Hort-Atkinson, R
Publisher: name: Liverpool John Moores University
Year: 2025

description: The benefits of mindfulness-based interventions (MBIs) are well-established for psychological and physical health. However, their utility concerning chronic pelvic pain (CPP) and chronic postoperative pain (CPOP) is currently limited. Further, the structure of traditional MBI programmes has been increasingly modified in attempts to improve accessibility and reduce costs; however, there is no consensus regarding how these amendments may affect outcomes. This thesis first reviews current literature focusing on CPP, CPOP, mindfulness-based approaches and applications, models of mindfulness and mechanisms of change. A systematic review of MBIs of non-standard durations for physical health is presented. The findings of this review demonstrated efficacy in several clinical populations, with no significant correlation between intervention duration and magnitude of change evident. Using these findings and the Liverpool Mindfulness Model as a framework, two MBIs were developed for CPP and patients due to undergo hysterectomy surgery and evaluated through randomised controlled studies. Findings are reported on both an intention-to-treat and per-protocol basis and interpreted in terms of statistical and clinical significance. The first study demonstrated that following exposure, CPP patients reported improvements in pain-related outcomes, psychological distress, and subjective well-being. The second study, which is the first known research examining the efficacy of an MBI as a pre-and postoperative rehabilitation tool for hysterectomy patients, demonstrated that preoperatively, MBI exposure protected participants against deteriorating surgical fears and state anxiety. Postoperatively, it was associated with superior pain-related outcomes, higher levels of global quality of recovery and improved psychological distress. Six months post-surgery, reports of new pain problems occurred at a lower frequency in MBI participants, suggesting that participation reduced the incidence of CPOP in this sample. Both studies also explored potential mechanisms of the MBIs thought to underlie positive change. MBI participation was associated with significantly increased dispositional mindfulness, improved emotion regulation and reduced use of maladaptive coping strategies. Research into the role of coping strategies such as distracting and ignoring and into illness perceptions, including personal and treatment control, is also extended. Across both studies, it was evident that low-dose MBIs can elicit beneficial outcomes in these populations; however, an extended duration of participation was associated with a greater magnitude of change. Finally, methodological considerations affecting the interpretation and generalisability of these findings are discussed, as are the original contributions of this programme of research. Recommendations for future research and clinical practice are also offered.

description: Learning graphs from data automatically has shown encouraging performance on clustering and semisupervised learning tasks. However, real data are often corrupted, which may cause the learned graph to be inexact or unreliable. In this paper, we propose a novel robust graph learning scheme to learn reliable graphs from real-world noisy data by adaptively removing noise and errors in the raw data. We show that our proposed model can also be viewed as a robust version of manifold regularized robust PCA, where the quality of the graph plays a critical role. The proposed model is able to boost the performance of data clustering, semisupervised classification, and data recovery significantly, primarily due to two key factors: 1) enhanced low-rank recovery by exploiting the graph smoothness assumption, 2) improved graph construction by exploiting clean data recovered by robust PCA. Thus, it boosts the clustering, semi-supervised classification, and data recovery performance overall. Extensive experiments on image/document clustering, object recognition, image shadow removal, and video background subtraction reveal that our model outperforms the previous state-of-the-art methods.

description: A scalar field theory with a $χ^\dagχϕ$ interaction is known to be unstable. Yet it has been used frequently without any sign of instability in standard text book examples and research articles. In order to reconcile these seemingly conflicting results, we show that the theory is stable if the Fock space of all intermediate states is limited to a {\em finite} number of $χ{\barχ}$ loops associated with field $χ$ that appears quadradically in the interaction, and that instability arises only when intermediate states include these loops to all orders.
