Pairing theory of the symmetry energy
Creators: name: Neergård, K.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: As a model which displays a picture of the symmetry energy as an energy of rotation in isospace of a Cooper pair condensate, a Hamiltonian with a pairing force and an interaction of isospins is analyzed in the Hartree-Bogolyubov (HB) plus Random Phase (RPA) approximation. The HB energy minus Lagrangian multiplier terms is shown to be locally minimized by a product of neutron and proton Bardeen-Cooper-Schrieffer states. Nambu-Goldstone RPA solutions appear due to global gauge invariance and isobaric invariance. In an idealized case of infinitely many equidistant single-nucleon levels, the symmetry energy is composed of contributions from the single-nucleon and isospin interaction energies and the RPA correlation energy. The contribution of the latter is dominated by a neutron-proton Nambu-Goldstone solution, which makes the total symmetry energy nearly proportional to T(T+1). Observations reported from Skyrme force calculations are discussed in the light of these results. Calculations with deformed Woods-Saxon single-nucleon levels give results similar to those of the idealized case, whereas a somewhat different behavior is found with spherical Woods-Saxon levels. The calculations with Woods-Saxon single-nucleon levels reproduce surprisingly well the empirical symmetry energy.

description: La gerencia agrícola constituye un aplanchador de cambios y trasformaciones que necesita la agricultura del país. Así, se evidencia en la producción científica relacionada a la temática. Esta deja abierta la posibilidad de recoger información que permita resignificarla. En consecuencia, el propósito de la investigación consiste en generar una interpretación desde la producción científica sobre la gerencia agrícola en Venezuela, año 2018 al 2023. La perspectiva metodológica es cualitativa, el paradigma interpretativo. Con relación a las técnicas de recolección de datos se utilizó como criterio de inclusión que los artículos fuesen arrojados por el buscador Google Académico para los años ya mencionados y responder al descriptor “Gerencia Agrícola en Venezuela” para así evitar la mención tangencial del tema. En total a estos criterios respondieron diez artículos. Para el ordenamiento y sistematización de la información, se recurrió a la creación de tablas que incluyen aspectos que describen las unidades de análisis. Aunado a ello, algunas técnicas interpretativas propias de la Teoría Fundamentada como, al microanálisis del contenido, codificación abierta y codificación axial. Así se generaron un total de cuatro categorías y subcategorías bases para la interpretación de tema objeto de estudio que en esencia dejan ver la necesidad de un gerente actualizado, líder, dispuesto a incursionar positivamente el logro de objetivos en un escenario por demás complejo.

Quantum Electrodynamics of Casimir Momentum: Momentum of the Quantum Vacuum?

Year: 2009
Subjects: subject: Quantum Physics (quant-ph)

description: The electromagnetic vacuum is known to have energy. It has been recently argued that the quantum vacuum can possess momentum, that adds up to the momentum of matter. This ``Casimir momentum'' is closely related to the Casimir effect, in which case energy is exchanged. In previous theory it was treated semi-classically. We present a non-relativistic quantum theory for the linear momentum of electromagnetic zero-point fluctuations, considering an harmonic oscillator subject to crossed, quasi-static magnetic and electric and coupled to the quantum vacuum. We derive a contribution of the quantum vacuum to the linear pseudo-momentum and give a new estimate for the achievable speed. Our analysis show that the effect exists and that it is finite.

description: A model is presented for generation of fast solar wind in coronal holes, relying on heating that is dominated by turbulent dissipation of MHD fluctuations transported upwards in the solar atmosphere. Scale-separated transport equations include large-scale fields, transverse Alfvenic fluctuations, and a small compressive dissipation due to parallel shears near the transition region. The model accounts for proton temperature, density, wind speed, and fluctuation amplitude as observed in remote sensing and in situ satellite data.

description: Othering begegnet uns nicht nur im geschriebenen Wort. Es kann sich ebenfalls in der Kombination von Bild und Text manifestieren. Wie wichtig eine Reflexion der Artikelbebilderung durch die Redaktion ist, möchte ich im Folgenden anhand eines Artikels der „Berliner Morgenpost“ veranschaulichen. Hierzu ist ein poststrukturalistisch orientierter Zugriff besonders geeignet, da hier die Auffassung vertreten wird, dass die Bedeutungen den Dingen nicht immanent sind, sondern sie ihnen diskursiv zugewiesen werden. Somit werden im Diskurs die Dinge erst als soziale Phänomene konstituiert, über die gesprochen bzw. geschrieben wird. Mittels einer solchen anti-essentialistischen Perspektive auf Identitäten kann die Forschung dazu beitragen, binäre Identitätskonstruktionen aufzudecken, zu hinterfragen und letztlich zu überwinden.
Leisure time of the first generation Italians in Vancouver, 1965-1966 : an exploratory study of the initial stage of the acculturation process
Creators: name: Willman, Pamela Maude Albertina
Publisher: name: University of British Columbia
Year: 2012

description: It has been observed that Italian immigrants in Vancouver do not make use of community resources such as the community centres, library, and the Young Women's Christian Association. This thesis investigates the reasons for this phenomenon by studying the acculturation of Italian immigrant families, with special reference to the use of leisure time. Twenty-two immigrant families were interviewed, and responses were recorded on a questionnaire by the interviewer. It was not possible to obtain a random sample, consequently the respondents tend to represent the economically more successful or those more active in church affairs. The results of the study tend to confirm the initial assumption that the Italian immigrant perpetuates an old world pattern familiar to him by confining his social, cultural and recreational activities to his family, kinship group, his church, and his ethnic organizations. However, the study also shows that these patterns are undergoing a gradual change. Mothers are participating in such strictly New World activities, as the Parent-Teacher Association. Some children take part in community centre activities. These initial steps towards using community resources are particularly noticeable in those first generation Italian immigrants who have been settled in their present neighbourhood for ten years or more, and in the second generation. The study will, it is hoped, be of interest to community planners. The use of typical North American resources is part of a cultural pattern to which some immigrant groups, at least, are not accustomed, and which they adopt only gradually. The speed of acculturation probably varies with the ethnic and cultural background of the groups.

description: Obesity is a complex disease of the body with an increase of the excessive amount of body fat. It is a health problem that increases the risk of other diseases such as cardiac disease, diabetes, Space high blood pressure, and certain cancers. Obesity occurs due to genetic, behavioral, metabolic, and hormonal influences on body weight. It occurs when the calories intake into the body is more and the activity is reduced, the excessive calories are stored as fat in the body. According to the American Association of clinical endocrinologist’s obesity has multiple pathophysiologic Origins. The pathophysiologic origins are physiologic, epigenetic, genetic, behavioral, social-cultural, and environmental.

description: We construct a low energy effective Lagrangian for the two-color QCD including the "vector" bosons (mesons with J^P=1^- and diquark baryons with J^P=1^+) in addition to the pseudo Nambu-Goldstone bosons with a degenerate mass M_π(mesons with J^P=0^- and baryons with J^P=0^+) based on the chiral symmetry breaking pattern of SU(2N_f) \to Sp(2N_f) in the framework of the hidden local symmetry. We investigate the dependence of the "vector" boson masses on the baryon number density μ_B. We show that the μ_B-dependence signals the phase transition of U(1)_B breaking. We find that it gives information about mixing among "vector" bosons: e.g. the mass difference between ρand ωmesons is proportional to the mixing strength between the diquark baryon with J^P=1^+ and the anti-baryon. We discuss the comparison with lattice data for two-color QCD at finite density.

Blockchain is viewed by many as a potentially transformative technology for the economic world. Using blockchain can facilitate the transition towards a knowledge-based economy, which involves creating value using the infinite resources of knowledge and expertise, in other words, developing wealth from an intangible capital or inheritance.  Thanks to its properties of immutability, traceability, and timestamping, blockchain technology holds great promise for a better economic future. It offers the potential for a more transparent, smooth, and democratic economic system for all stakeholders involved. This document explores the potential applications of the latest blockchain technology and presents its projected implementation in fields such as commerce, agriculture, and more. It highlights the crucial contributions of blockchain in advancing knowledge economy.
"Clumpiness" Mixing in Complex Networks

description: Three measures of clumpiness of complex networks are introduced. The measures quantify how most central nodes of a network are clumped together. The assortativity coefficient defined in a previous study measures a similar characteristic, but accounts only for the clumpiness of the central nodes that are directly connected to each other. The clumpiness coefficient defined in the present paper also takes into account the cases where central nodes are separated by a few links. The definition is based on the node degrees and the distances between pairs of nodes. The clumpiness coefficient together with the assortativity coefficient can define four classes of network. Numerical calculations demonstrate that the classification scheme successfully categorizes 30 real-world networks into the four classes: clumped assortative, clumped disassortative, loose assortative and loose disassortative networks. The clumpiness coefficient also differentiates the Erdos-Renyi model from the Barabasi-Albert model, which the assortativity coefficient could not differentiate. In addition, the bounds of the clumpiness coefficient as well as the relationships between the three measures of clumpiness are discussed.

Search for Solar Axions with the CDMS-II Experiment
Creators: name: Bruch, T.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The CDMS-II experiment operates 19 germanium detectors with a mass of 250g each in a very low background environment. Originally designed for the search for Dark Matter the experiment can also detect solar axions by Primakoff conversion to photons. The Bragg condition for X-ray momentum transfer in a crystal allows for coherent amplification of the Primakoff process. Since the orientation of the crystal lattice with respect to the Sun changes with daytime an unique pattern in time and energy of solar axion conversions is expected. The low background ~1.5 counts/kg/day/keV and knowledge of the exact orientation of all three crystal axes with respect to the Sun make the CDMS-II experiment very sensitive to solar axions. In contrast to helioscopes, the high mass region < 1 keV can also be probed effectively. The alternating orientations of the individual crystals in the experimental setup provide different patterns of solar axion conversion, making a false positive result extremely unlikely. The result of an analysis of 289 kg-days of exposure resulted in a null observation of solar axion conversion. This analysis sets an upper limit on the axion photon coupling constant of g_{aγγ} < 2.6 x 10^{-9} GeV{-1} at a 95% confidence level.

description: Spośród setek konfliktów o przebieg granic w XX-wiecznej Europie ten, który toczył się o Orawę i Spisz między Polską a Czechosłowacją i Słowacją, może śmiało kandydować do tytułu najbardziej kuriozalnego. Dwadzieścia parę ubogich górskich wiosek kilkukrotnie przechodziło z rąk do rąk i skupiało na sobie uwagę polityków, dyplomatów oraz opinii publicznej w Polsce, w Czechach i Słowacji. Praca Marcela Jesenskiego opisuje ten spór z perspektywy tradycyjnej historii stosunków międzynarodowych, podzielając zarazem tej perspektywy mocne i niektóre słabe strony. Książka jest zatem faktograficznie dokładna i dobrze zakorzeniona źródłowo, a jednocześnie ateoretyczna i przez to pozbawiona warstwy wyjaśniającej.

Autorzy rekrutują się spośród uczestników konferencji przeprowadzonej w 2012 roku, która koncentrowała się na problemach i kategorii nowoczesności w XX wieku. Główne pytanie badawcze przyświecające całości pracy sformułowane zostało w następujący sposób: jak uwarunkowania czasowe i przestrzenne wpłynęły na region Europy Środkowej i Wschodniej, w szczególności na jego (częściowe) przekształcenie się z regionu rolniczego w przemysłowy. Poszczególne elementy pracy zbiorowej dotykają różnorodnych problemów społecznych, ekonomicznych, logistycznych, urbanistycznych, czy architektonicznych, czyniąc z całego opracowania interesujące studium o interdyscyplinarnym charakterze. W konsekwencji praca stanowi ważną pozycję przyczyniającą się do zdefiniowania, względnie lepszego zrozumienia, tożsamości tak różnorodnego i skomplikowanego regionu jakim jest Europa Środkowa i Wschodnia.

description: A new formulation of electromagnetism based on linear differential commutator brackets is developed. Maxwell equations are derived, using these commutator brackets, from the vector potential $\vec{A}$, the scalar potential $ϕ$ and the Lorentz gauge connecting them. With the same formalism, the continuity equation is written in terms of these new differential commutator brackets. Keywords: Mathematical formulation, Maxwell's equations

description: „Memoirs are not history. But they can be an important source and material for history" (S. 7) Mit diesen Worten beschrieb Emanuel Scherer, der damalige Generalsekretär des Allgemeinen Jüdischen Arbeiterbunds (Bund), einer 1897 in Vilnius gegründeten jüdisch-sozialistischen Partei, 1960 in den USA den Wert des damals jüngst veröffentlichten Buches Tsvantsig yor in Varshever „Bund" (Zwanzig Jahre im Warschauer „Bund") von Bernard Goldstein. Ein Buch, in dem Goldstein die Erinnerungen an seine Zeit als aktives Mitglied des Bund und der jüdischen Community im Warschau der Zweiten Polnischen Republik verarbeitet. [1] Goldsteins Memoiren gehören damit zu den wenigen verfügbaren Berichten eines direkt Beteiligten. In ihnen schildert der Autor mit großem Detailreichtum die alltäglichen politischen Kämpfe sowie das soziale und kulturelle Leben des Bund im unabhängigen Polen, wobei es ihm sehr gut gelingt, seine höchsteigenen Erlebnisse in Bezug zu setzen zum großen Ganzen der Geschichte des Bund und Europas in jenen Jahren.

description: In hierarchical structure formation models of disk galaxies, a dark matter disk forms as massive satellites are preferentially dragged into the disk-plane where they dissolve. Here, we quantify the importance of this dark disk for direct and indirect dark matter detection. The low velocity of the dark disk with respect to the Earth enhances detection rates in direct detection experiments at low recoil energy. For WIMP masses M_{WIMP} >~ 50 GeV, the detection rate increases by up to a factor of 3 in the 5 - 20 keV recoil energy range. Comparing this with rates at higher energy is sensitive to M_{WIMP}, providing stronger mass constraints particularly for M_{WIMP}>~100 GeV. The annual modulation signal is significantly boosted by the dark disk and the modulation phase is shifted by ~3 weeks relative to the dark halo. The variation of the observed phase with recoil energy determines M_{WIMP}, once the dark disk properties are fixed by future astronomical surveys. The low velocity of the particles in the dark disk with respect to the solar system significantly enhances the capture rate of WIMPs in the Sun, leading to an increased flux of neutrinos from the Sun which could be detected in current and future neutrino telescopes. The dark disk contribution to the muon flux from neutrino back conversion at the Earth is increased by a factor of ~5 compared to the SHM, for rho_d/rho_h=0.5.

description: We use the harmonic maps ansatz to find exact solutions of the Einstein-Maxwell-Dilaton-Axion (EMDA) equations. The solutions are harmonic maps invariant to the symplectic real group in four dimensions $Sp(4,\Rreal)\sim O(5)$. We find solutions of the EMDA field equations for the one and two dimensional subspaces of the symplectic group. Specially, for illustration of the method, we find space-times that generalise the Schwarzschild solution with dilaton, axion and electromagnetic fields.

description: We have used Spitzer and its IRAC camera to search for the transit of the super-Earth HD 40307b. The transiting nature of the planet could not be firmly discarded from our first photometric monitoring of a transit window because of the uncertainty coming from the modeling of the photometric baseline. To obtain a firm result, two more transit windows were observed and a global Bayesian analysis of the three IRAC time series and the HARPS radial velocities was performed. Unfortunately, any transit of the planet during the observed phase window is firmly discarded, while the probability that the planet transits but that the eclipse was missed by our observations is nearly negligible (0.26%).

description: Scanning transmission electron microscopy (STEM) allows to gain quantitative information on the atomic‑scale structure and composition of materials, satisfying one of todays major needs in the development of novel nanoscale devices. The aim of this study is to quantify the impact of inelastic, i.e. plasmon excitations (PE), on the angular dependence of STEM intensities and answer the question whether these excitations are responsible for a drastic mismatch between experiments and contemporary image simulations observed at scattering angles below∼40 mrad. For the two materials silicon and platinum, the angular dependencies of elastic and inelastic scattering are investigated. We utilize energy filtering in two complementary microscopes, which are representative for the systems used for quantitative STEM, to form position‑averaged diffraction patterns as well as atomically resolved 4D STEM data sets for different energy ranges. The resulting five‑dimensional data are used to elucidate the distinct features in real and momentum space for different energy losses. We find different angular distributions for the elastic and inelastic scattering, resulting in an increased low‑angle intensity (∼10–40 mrad). The ratio of inelastic/elastic scattering increases with rising sample thickness, while the general shape of the angular dependency is maintained. Moreover, the ratio increases with the distance to an atomic column in the low‑angle regime. Since PE are usually neglected in image simulations, consequently the experimental intensity is underestimated at these angles, which especially affects bright field or low‑angle annular dark field imaging. The high‑angle regime, however, is unaffected. In addition, we find negligible impact of inelastic scattering on first‑ moment imaging in momentum‑resolved STEM, which is important for STEM techniques to measure internal electric fields in functional nanostructures. To resolve the discrepancies between experiment and simulation, we present an adopted simulation scheme including PE. This study highlights the necessity to take into account PE to achieve quantitative agreement between simulation and experiment. Besides solving the fundamental question of missing physics in established simulations, this finally allows for the quantitative evaluation of low‑angle scattering, which contains valuable information about the material investigated.
Parameter degeneracies and (un)predictability of gravitational microlensing events

description: (abridged) Some difficulties in determining the physical properties that lead to observed anomalies in microlensing light curves, such as the mass and separation of extra-solar planets orbiting the lens star, or the relative source-lens parallax, are already anchored in factors that limit the amount of information available from ordinary events and in the adopted parametrization. Moreover, a real-time detection of deviations from an ordinary light curve while these are still in progress can only be done against a known model of the latter, and such is also required for properly prioritizing ongoing events for monitoring in order to maximize scientific returns. Despite the fact that ordinary microlensing light curves are described by an analytic function that only involves a handful of parameters, modelling these is far less trivial than one might be tempted to think. A well-known degeneracy for small impacts, and another one for the initial rise of an event, makes an interprediction of different phases impossible, while determining a complete set of model parameters requires the assessment of the fundamental characteristics of all these phases. While the wing of the light curve provides valuable information about the time-scale that absorbs the physical properties, the peak flux of the event can be meaningfully predicted only after about a third of the total magnification has been reached. Parametrizations based on observable features not only ease modelling by bringing the covariance matrix close to diagonal form, but also allow good predictions of the measured flux without the need to determine all parameters accurately. Campaigns intending to infer planet populations from observed microlensing events need to invest some time into acquiring data that allows to properly determine the magnification function.

description: Quantitative scanning transmission electron microscopy (STEM) is a powerful tool for the characterization of nano-materials. Absolute composition determination for ternary III–V semiconductors by direct comparison of experiment and simulation is well established. Here, we show a method to determine the composition of quaternary III–V semiconductors with two elements on each sub lattice from the intensities of one STEM image. As an example, this is applied to (GaIn)(AsBi). The feasibility of the method is shown in a simulation study that also explores the influence of detector angles and specimen thickness. Additionally, the method is applied to an experimental STEM image of a (GaIn)(AsBi) quantum well grown by metal organic vapour phase epitaxy. The obtained concentrations are in good agreement with X-ray diffraction and photoluminescence results.
