description: The order of the Coulomb-Higgs transition in the U(1)-Higgs model with unfrozen modulus of the scalar field is studied. Large lattices (up to $24^4$ in one case) and high statistics are used. We fix $β=1.15$ and explore specially a region of $λ$-values where metastability is observed. We study the thermodynamical limit of several observables, in particular, the latent heat, the specific heat, the decrement of the free energy between the maxima and the central minimum of the two-peaked histogram, the Binder cumulant and the displacement of the critical coupling with the lattice size. The results point towards a second order transition for $λ\gtrsim 0.005$, while for smaller values of $λ$ the strong metastability growing with the lattice size seems to derive from a first order character.

description: Protected area downgrading, downsizing, and degazettement (PADDD) has been documented worldwide, but its impacts on biodiversity are poorly understood. To fill this knowledge gap, we reviewed historical documents to identify legal changes that altered the boundaries of Yosemite National Park. We identified two downsizes and five additions between 1905 and 1937 that reduced the size of Yosemite National Park by 30%. To examine the effects of these downsizing events on habitat fragmentation by roads, we compared protected, never-protected, and downsized lands at three spatial scales using four habitat fragmentation metrics: road density, fragment (land surrounded by roads) area-to-perimeter ratio, fragment area, and fragment density. In general, lands that were removed from protection, e.g., downsized, were more highly fragmented than protected lands and indistinguishable from never-protected lands. Lands where downsizes were reversed were less fragmented than lands where downsizes were not reversed. These results suggest that protected area downsizing may exacerbate habitat fragmentation, a key contributor to biodiversity loss globally. Furthermore, the case study in Yosemite National Park demonstrates that iconic protected areas in developed countries are not immune to downsizing. These findings underscore the need to account for PADDD and governance histories in ecological research, monitoring, and evaluation. As we move toward more evidence-based conservation policy, a rigorous understanding of PADDD is essential to ensure that protected areas fulfill their promise as a strategy for conserving global biodiversity.

A Spin Model for Investigating Chirality

Year: 1995

subject: FOS: Physical sciences

description: Spin chirality has generated great interest recently both from possible applications to flux phases and intrinsically, as an example of a several-site magnetic order parameter that can be long-ranged even where simpler order parameters are not. Previous work (motivated by the flux phases) has focused on antiferromagnetic chiral order; we construct a model in which the chirality orders ferromagnetically and investigate the model's behavior as a function of spin. Enlisting the aid of exact diagonalization, spin-waves, perturbation theory, and mean fields, we conclude that the model likely has long-ranged chiral order for spins 1 and greater and no non-trivial chiral order for spin 1/2.

description: In this work we deepen and complement the analysis on the dynamics of Low Earth Orbits (LEO), carried out by the authors within the H2020 ReDSHIFT project, by characterising the evolution of the eccentricity of a large set of orbits in terms of the main frequency components. Decomposing the quasi-periodic time series of eccentricity of a given orbit by means of a numerical computation of Fourier transform, we link each frequency signature to the dynamical perturbation which originated it in order to build a frequency chart of the LEO region. We analyse and compare the effects on the eccentricity due to solar radiation pressure, lunisolar perturbations and high degree zonal harmonics of the geopotential both in the time and frequency domains. In particular, we identify the frequency signatures due to the dynamical resonances found in LEO and we discuss the opportunity to exploit the corresponding growth of eccentricity in order to outline decommissioning strategies.

description: Action and energy flux-tube profiles are computed, in SU(2) with beta=2.4,2.5, for two quarks up to 1 fm apart and for which the colour fields are in their ground state (A_1g) and the first (E_u) and higher (A'_1g) excited gluonic states. When these profiles are integrated over all space, a scaling comparison is made between the beta=2.4 and 2.5 data. Using sum rules, these integrated forms also permit an estimate to be made of generalised beta-functions giving b(2.4)=-0.312(15), b(2.5)=-0.323(9), f(2.4)=0.65(1) and f(2.5)=0.68(1). When the profiles are integrated only over planes transverse to the interquark line and assuming underlying string features, scaling comparisons are again made near the centres of the interquark line for the largest interquark distances. For the A'_{1g} case, some of the profiles exhibit a 'dip-like' structure characteristic of the Isgur-Paton model.

Diffractive charm jet production at hadron colliders in the two-gluon exchange model

Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a calculation of diffractive charm jet production at hadron colliders in perturbative QCD based on the two-gluon exchange model. Differing from the previous calculations, we abandon the use of the effective color-singlet vitual gluon simplification, and use the real gluon in the calculations for the partonic process. We find the final result is free of the linear singularities due to the small transverse momenta of the exchanged two gluons. In the leading logarithmic approximation (LLA) in QCD, this process is related to the off-diagonal gluon density in the proton. As a result, this process may provide a wide window for testing the two-gluon exchange model, and may be particularly useful in studying the small $x$ physics. In comparison, the diffractive bottom jet production is also discussed, and is found to be important only for large transverse momentum of the jet.

The Sphaleron in a Magnetic Field and Electroweak Baryogenesis

description: The presence of a primordial magnetic field in the early universe affects the dynamic of the electroweak phase transition enhancing its strength. This effect may enlarge the window for electroweak baryogenesis in the minimal supersymmetric extension of the standard model or even resurrect the electroweak baryogenesis scenario in the standard model. We compute the sphaleron energy in the background of the magnetic field and show that, due to the sphaleron dipole moment, the barrier between topologically inequivalent vacua is lowered. Therefore, the preservation of the baryon asymmetry calls for a much stronger phase transition than required in the absence of a magnetic field. We show that this effect overwhelms the gain in the phase transition strength, and conclude that magnetic fields do not help electroweak baryogenesis.

Logarithmic Finite-Size Correction in Non-neutral Two-Component Plasma on Sphere
Creators: name: Šamaj, Ladislav
Publisher: name: arXiv
Year: 2018
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We consider a general two-component plasma of classical pointlike charges $+e$ ($e$ is say the elementary charge) and $-Z e$ (valency $Z=1,2,\ldots$), living on the surface of a sphere of radius $R$. The system is in thermal equilibrium at the inverse temperature $β$, in the stability region against collapse of oppositely charged particle pairs $βe^2 < 2/Z$. We study the effect of the system excess charge $Q e$ on the finite-size expansion of the (dimensionless) grand potential $βΩ$. By combining the stereographic projection of the sphere onto an infinite plane, the linear response theory and the planar results for the second moments of the species density correlation functions we show that for any $βe^2 < 2/Z$ the large-$R$ expansion of the grand potential is of the form $βΩ\sim A_V R^2 + [χ/6 - β(Qe)^2/2] \ln R$, where $A_V$ is the non-universal coefficient of the volume (bulk) part and the Euler number of the sphere $χ=2$. The same formula, containing also a non-universal surface term proportional to $R$, was obtained previously for the disc domain ($χ=1$), in the case of the symmetric $(Z=1)$ two-component plasma at the collapse point $βe^2=2$ and the jellium model $(Z\to 0)$ of identical $e$-charges in a fixed neutralizing background charge density at any coupling $βe^2$ being an even integer. Our result thus indicates that the prefactor to the logarithmic finite-size expansion does not depend on the composition of the Coulomb fluid and its non-universal part $-β(Qe)^2/2$ is independent of the geometry of the confining domain.

description: We analyze the theoretical implications of the new KTeV measurement of direct CP-violation in K->pi pi decays. The result is found consistent with the Standard Model for low values of the strange quark mass m_s. If the hadronic parameters B_6^{(1/2)} and B_8^{(3/2)} satisfy 2 B_6^{(1/2)} - B_8^{(3/2)} < 2, as suggested by lattice and 1/N_c calculations, we find an upper bound of 110 MeV for m_s (2 GeV)$. We parametrize potential new physics contributions to ε'/εand illustrate their correlation with upper bounds on m_s. Finally we discuss a non-perturbative mechanism, which is not contained in the existing calculations of B_6^{(1/2)}. This mechanism enhances B_6^{(1/2)} and thereby leads to a better understanding of the Delta I=1/2 rule and the high measured value of Re (ε^\prime/ε)

description: Orbital tomography has recently been established as a technique to reconstruct molecular orbitals directly from photoemission data using iterative phase retrieval algorithms. In this work, we present a detailed description of steps for processing of the photoemission data followed by an improved iterative phase retrieval procedure and the interpretation of reconstructed two-dimensional orbital distributions. We address the issue of background subtraction by suggesting a signal restoration routine based on the maximization of mutual information algorithm and solve the problem of finding the geometrical center in the reconstruction by using a tight-centered object support in a two-step phase retrieval procedure. The proposed image processing and improved phase retrieval procedures are used to reconstruct the highest occupied molecular orbital of pentacene on Ag(110), using photoemission data only. The results of the reconstruction agree well with the density functional theory simulation, modified to comply with the experimental conditions. By comparison with photoelectron holography, we show that the reconstructed two-dimensional orbital distribution can be interpreted as a superposition of the in-focus orbital distribution evaluated at the z = 0 plane and out-of-focus distributions evaluated at other z = const planes. Three-dimensional molecular orbital distributions could thus be reconstructed directly from two-dimensional photoemission data, provided the axial resolution of the imaging system is high enough.

description: This paper presents a study on mutual speech variation influences in a human-computer setting. The study highlights behavioral patterns in data collected as part of a shadowing experiment, and is performed using a novel end-to-end platform for studying phonetic variation in dialogue. It includes a spoken dialogue system capable of detecting and tracking the state of phonetic features in the user's speech and adapting accordingly. It provides visual and numeric representations of the changes in real time, offering a high degree of customization, and can be used for simulating or reproducing speech variation scenarios. The replicated experiment presented in this paper along with the analysis of the relationship between the human and non-human interlocutors lays the groundwork for a spoken dialogue system with personalized speaking style, which we expect will improve the naturalness and efficiency of human-computer interaction.

The structural/morphological features of the synthesized polymer nanocomposite films have been investigated in detail using X-ray diffraction, Fourier transform infra-red spectroscopy, field emission scanning electron microscope, and atomic force microscopy techniques. The film PEO-PVP+NaPF6 O/Na:8 exhibits highest ionic conductivity ~5.92x10-6 S cm-1 at 40 oC and ~2.46x10-4 S cm-1 at 100 oC. The temperature dependent conductivity shows Arrhenius type behavior and activation energy decreases with the addition of salt. The high temperature (100 oC) conductivity monitoring is done for the optimized PEO-PVP+NaPF6 O/Na:8 highly conductive system and the conductivity is still maintained stable up to 160 h (approx. 7 days). The thermal transitions parameters were measured by the differential scanning calorimetry (DSC) measurements. The prepared polymer electrolyte film displays the smoother surface in addition of salt and a thermal stability up to 300 oC............

description: Analytic and numeric approximations are studied in detail for a hydrodynamic parameterization of single-particle spectra and two-particle correlation functions in high energy hadron-proton and heavy ion reactions. Two very different sets of model parameters are shown to result in similarly shaped correlation functions and single particle spectra in a rather large region of the momentum space. However, the absolute normalization of the single-particle spectra is found to be highly sensitive to the choice of the model parameters. For data fitting the analytic formulas are re-phrased in terms of parameters of direct physical meaning, like mean transverse flow. The difference between the analytic and numeric approximations are determined as an analytic function of source parameters.

description: This thesis describes the design, construction, and testing of a Wearable Knee Angle Sensor (WKAS) device that measures knee flexion angle designed for operation in various competitive sports. The requirement is to design a rugged wearable (i.e., low weight, low profile) sensor that can be worn in game situations in contact sports. The sensor can be used for performance assessment (e.g., leg motion while sprinting) and for injury prevention (e.g., leg motion leading to specific injuries). An analysis of alternate sensor options was conducted leading to selection of a Flex-Sensor. The WKAS was configured with a Flex Sensor mounted in a sensor-sleeve behind the knee that is attached to a knee sleeve. An Arduino was used to collect and process the data and stored it on an SD card. The data from the SD card can then be downloaded and analyzed in visualization software (simulation) developed in MATLAB. The accuracy of the sensor was assessed, and future improvements are proposed.

description: A computer-aided solution for the task performed by a Maritime Lawyer is presented in this thesis. It facilitates the process of searching a set of rules from across different Maritime Laws that are applicable in a certain given situation and provides analytical capabilities that include verification of the selected rules against inconsistency as well as reasoning with them. The analyses are meant to decide the applicability of actions from the selected rule set after a careful consideration of possible inconsistencies that may appear in the applicable rules. The analytical techniques require that Maritime Laws be represented as Production Systems. The production rules are first normalized and transformed into an equivalent Petri Net representation. The structural and behavioral analysis of the Petri Net is then performed to look for properties of the net corresponding to useless, incomplete, cyclic, redundant and inconsistent cases. The structural analysis is done by an already existing approach to identify the cases of useless, incomplete and circular rules. The behavioral analysis is done by using a formal methodology of model x checking that explores the state space of the Petri Net to verify the properties corresponding to redundant and inconsistent rules. A reasoning mechanism is also proposed, which uses the Petri Net representation, to answer queries about the applicability of actions from the selected set of rules. The combined use of the verification results and the reasoning mechanism will help a Maritime Lawyer in identifying a course of action for a given situation of interest that is supported by the applicable Maritime Laws.

description: Aluminium alloy AA7075 (Al-Zn-Mg-Cu) specimens were prepared using selective laser melting, also known as powder bed fusion additive manufacturing. In the as-manufactured state, which represents a locally rapidly solidified condition, the prevalence of a previously unreported icosahedral quasicrystal with 5-fold symmetry was observed. The icosahedral quasicrystal, which has been termed nu-phase, was comprised of Zn, Cu and Mg.

description: It has been suggested that dark matter is a superfluid of particles whose masses are on the rough order of $10^{-22}$ eV. Since the occupation numbers are huge, the state is coherent, and the speeds typical of orbital velocities in halos, it has generally been assumed that a classical effective non-relativistic treatment is adequate. However, the Compton wavelength would be $\sim 1\, {\rm pc}$, and around the Compton scale concerns about some aspects of quantum measurement theory, known in principle but not quantitatively significant in previous cases, become pronounced. I estimate here the stress--energy operator, averaged over a few Compton wavelengths; a rough but useful approximation has a remarkably simple form. Conventional quantum measurement theory gives physically unacceptable results: a thought-experiment to measure the stress--energy is described which would involve only a modest apparatus but would excite particles in the observation volume to relativistic energies; these particles would escape the Galaxy, and there would be a substantial violation of energy conservation. Related foundational questions come up: the meaning of measurements of observables with continuous spectra, and the problem of predicting when measurements occur. The effective classical theory of fuzzy dark matter is not affected; however, the underlying quantum theory cannot be regarded as satisfactory without resolving these issues. But we may interpret the results more broadly. The macroscopic Compton scale amplifies inadequacies of measurement theory which have not previously seemed pressing.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the relations between the K_{l3} and tau --> K pi nu_tau decays using the meson dominance approach. First, the experimental branching fractions (BF) for K^-_{e3} and K^0_{e3} are used to fix two normalization constants (isospin invariance is not assumed). Then, the BF of tau^- --> K^*(892)^- nu_tau is calculated in agreement with experiment. We further argue that the nonzero value of the slope parameter lambda_0 of the K^-_{mu3} and K^0_{mu3} form factors f_0(t) implies the existence of the tau^- --> K_0^*(1430)^- nu_tau decay. We calculate its BF, together with BF's of the K^-_{mu3}, K^0_{mu3}, tau- --> K^- pi^0 nu_tau, and tau- --> antiK^0 pi^0 nu_tau decays, as a function of the lambda_0 parameter. At some value of lambda_0, different for charged and neutral kaons, calculated BF's seem to match existing data and a prediction is obtained for the tau^- --> K pi nu decays going through the K_0^*(1430)^- resonance.

description: We develop a formalism for performing real space renormalization group transformations of the "decimation type" using perturbation theory. The type of transformations beyond $d=1$ is nontrivial even for free theories. We check the formalism on solvable case of $O(N)$ symmetric Heisenberg chain. The transformation is particularly useful to study asymptotically free theories. Results for one class of such models, the d=2 O(N) symmetric $σ$ models ($N\ge 3$) for decimation with scale factor $η=2$ (when quarter of the points is left) are given as an example.

Hamiltonian simulation with nearly optimal dependence on spectral norm

description: We present a quantum algorithm for approximating the real time evolution $e^{-iHt}$ of an arbitrary $d$-sparse Hamiltonian to error $ε$, given black-box access to the positions and $b$-bit values of its non-zero matrix entries. The complexity of our algorithm is $\mathcal{O}((t\sqrt{d}\|H\|_{1 \rightarrow 2})^{1+o(1)}/ε^{o(1)})$ queries and a factor $\mathcal{O}(b)$ more gates, which is shown to be optimal up to subpolynomial factors through a matching query lower bound. This provides a polynomial speedup in sparsity for the common case where the spectral norm $\|H\|\ge\|H\|_{1 \rightarrow 2}$ is known, and generalizes previous approaches which achieve optimal scaling, but with respect to more restrictive parameters. By exploiting knowledge of the spectral norm, our algorithm solves the black-box unitary implementation problem -- $\mathcal{O}(d^{1/2+o(1)})$ queries suffice to approximate any $d$-sparse unitary in the black-box setting, which matches the quantum search lower bound of $Ω(\sqrt{d})$ queries and improves upon prior art [Berry and Childs, QIP 2010] of $\tilde{\mathcal{O}}(d^{2/3})$ queries. Combined with known techniques, we also solve systems of sparse linear equations with condition number $κ$ using $\mathcal{O}((κ\sqrt{d})^{1+o(1)}/ε^{o(1)})$ queries, which is a quadratic improvement in sparsity.

Η περίοδος της πανδημίας Covid-19 ανέδειξε τον τομέα αυτό και επιτάχυνε τις εξελίξεις, δημιουργώντας γόνιμο έδαφος για τον εξελισσόμενο ψηφιακό μετασχηματισμό.

Ανεξάρτητα ασφαλώς από την επιτυχία του συστήματος, το Πληροφοριακό Σύστημα Invoices οφείλει να ακολουθεί τον δυναμικό χαρακτήρα της Ηλεκτρονικής Διακυβέρνησης και να συνεχίσει να εξελίσσεται.

description: This thesis proposes an extension to the Baconian-Fuzzy probabilities previously developed as part of research into Wigmorean Networks (WigNets), providing a framework for evaluating the appropriate degree of confidence for a derived probability. We first give an overview of the existing structure of such probability evaluation. Based on existing Department of Defense (DoD) and Intelligence Community (IC) confidence evaluation guidelines, we establish criteria for the addition of confidence to the current network structure. Based on this analysis of existing guidelines, we present an empirically grounded framework for the evaluation of the degree of confidence that should be associated with a given probability. We next give justification for the behavior of this framework with a comparison with the measure theory underlying the establishment of other, similar Fuzzy confidence intervals.

description: We study the zeros in the complex plane of the partition function for the Ising model coupled to $2d$ quantum gravity for complex magnetic field and for complex temperature. We compute the zeros by using the exact solution coming from a two matrix model and by Monte Carlo simulations of Ising spins on dynamical triangulations. We present evidence that the zeros form simple one-dimensional patterns in the complex plane, and that the critical behaviour of the system is governed by the scaling of the distribution of singularities near the critical point.

description: We use the Lyon-Fedder-Mobarry global magnetohydrodynamics model to study the effects of the interplanetary magnetic field (IMF) $\mathit{B}_{y}$ component on the coupling between the solar wind and magnetosphere-ionosphere system when IMF $\mathit{B}_{z}$ $>$0. We describe the evolution of how a magnetospheric $\mathit{B}_{y}$ component is induced on closed field lines during these conditions. Starting from dayside lobe reconnection, the magnetic tension on newly reconnected field lines redistribute the open flux asymmetrically between the two hemispheres. This results in asymmetric magnetic energy density in the lobes. Shear flows are induced to restore equilibrium, and these flows are what effectively induces a local $\mathit{B}_{y}$ component. We show the radial dependence of the induced $\mathit{B}_{y}$ and compare the results to the induced $\mathit{B}_{y}$ during southward IMF conditions. We also show the response and reconfiguration time of the inner magnetosphere to IMF $\mathit{B}_{y}$ reversals during northward IMF $\mathit{B}_{z}$. A superposed epoch analysis of magnetic field measurements from seven Geostationary Operational Environmental Satellite spacecraft at different local times both for negative-to-positive and positive-to-negative IMF $\mathit{B}_{y}$ reversals is presented. We find that the induced $\mathit{B}_{y}$ responds within 16 min of the arrival of IMF $\mathit{B}_{y}$ at the bow shock, and it completely reconfigures within 47 min.

description: Slides of the Presentation at the  "Data Steward goes Germany" workshop in Dresden, Germany on  25-26 September 2023.

In the context of a research institution, a Data Steward assumes a position of paramount importance, as it directly contributes to the efficient management and maximisation of the institution's valuable research data assets. The presence of a skilled and transformative Data Steward becomes instrumental in overcoming the silos that tend to emerge within institutions, allowing for the seamless integration and coordination of data-related efforts across various departments and disciplines. By bridging these silos, the Data Steward plays a crucial role in promoting the principles of open science and fostering a collaborative research environment. However, many institutions need help comprehending the precise nature and scope of the Data Steward role. This lack of clarity often leads to ambiguity in identifying skills and expertise. Additionally, integrating the Data Steward position within the organisational structure is also conducted heterogeneously across institutions due to the need for a well-defined framework for the Data Steward's responsibilities and reporting lines, which may hinder their ability to realise their transformative potential.

Therefore, some aspects are crucial and need further discussion in this context, such as 1) The need to embed Data Stewardship into a strategic management position within the institution organigram, 2) The importance of the cross-cutting multidisciplinary competencies, 3) The essential requirement for a certain degree of research experience and 4) The project management skills.
