description: Luminous accreting stellar mass and supermassive black holes produce power-law continuum X-ray emission from a compact central corona. Reverberation time lags occur due to light travel time-delays between changes in the direct coronal emission and corresponding variations in its reflection from the accretion flow. Reverberation is detectable using light curves made in different X-ray energy bands, since the direct and reflected components have different spectral shapes. Larger, lower frequency, lags are also seen and are identified with propagation of fluctuations through the accretion flow and associated corona. We review the evidence for X-ray reverberation in active galactic nuclei and black hole X-ray binaries, showing how it can be best measured and how it may be modelled. The timescales and energy-dependence of the high frequency reverberation lags show that much of the signal is originating from very close to the black hole in some objects, within a few gravitational radii of the event horizon. We consider how these signals can be studied in the future to carry out X-ray reverberation mapping of the regions closest to black holes.

description: To explore the strength, isospin dependence, and density dependence of the in-medium spin-orbit coupling that is poorly known but relevant for understanding the structure of rare isotopes, the nucleon spin up-down differential transverse flow is studied systematically by varying the beam energy and impact parameter of Au+Au collisions within a spin-isospin dependent transport model recently developed for investigating spin-related phenomena in intermediate-energy heavy-ion collisions. The optimal reaction conditions for delineating and disentangling effects of different terms in the spin-orbit coupling are discussed.

description: The onset of a solar eruption is formulated here as either a magnetic catastrophe or as an instability. Both start with the same equation of force balance governing the underlying equilibria. Using a toroidal flux rope in an external bipolar or quadrupolar field as a model for the current-carrying flux, we demonstrate the occurrence of a fold catastrophe by loss of equilibrium for several representative evolutionary sequences in the stable domain of parameter space. We verify that this catastrophe and the torus instability occur at the same point; they are thus equivalent descriptions for the onset condition of solar eruptions.

description: Conventional radially-local neoclassical calculations become inadequate if the radial gradient scale lengths of the H-mode pedestal become as small as the poloidal ion gyroradius. Here, we describe a radially global $δf$ continuum code that generalizes neoclassical calculations to allow stronger gradients. As with conventional neoclassical calculations, the formulation is time-independent and requires only the solution of a single sparse linear system. We demonstrate precise agreement with an asymptotic analytic solution of the radially global kinetic equation in the appropriate limits of aspect ratio and collisionality. This agreement depends crucially on accurate treatment of finite orbit width effects.

Neutral interstellar helium parameters based on Ulysses/GAS and IBEX-Lo observations: what are the reasons for the differences?

description: Recent analysis of the interstellar helium fluxes measured in 2009-2010 at Earth orbit by the Interstellar Boundary Explorer (IBEX) has suggested that the interstellar velocity (both direction and magnitude) is inconsistent with that derived previously from Ulysses/GAS observations made in the period from 1990 to 2002 at 1.5-5.5 AU from the Sun. Both results are model-dependent and models that were used in the analyses are different. In this paper, we perform an analysis of the Uysses/GAS and IBEX-Lo data using our state-of-the-art 3D time-dependent kinetic model of interstellar atoms in the heliosphere. For the first time we analyze Ulysses/GAS data from year 2007, the closest available Ulysses/GAS observations in time to the IBEX observations. We show that the interstellar velocity derived from the Ulysses 2007 data is consistent with previous Ulysses results and does not agree with the velocity derived from IBEX. This conclusion is very robust since, as is shown in the paper, it does not depend on the ionization rates adopted in theoretical models. We conclude that Ulysses data are not consistent with the new LISM velocity vector from IBEX. In contrast, IBEX data, in principle, could be explained with the LISM velocity vector derived from the Ulysses data. This is possible for the models with the interstellar temperature increased from 6300 K to 9000 K. There is a need to perform further study of possible reasons for the broadening of the helium signal core measured by IBEX. This could be an instrumental effect or due to unconsidered physical processes.

description: We propose schemes for the detection of topological defect dark matter using pulsars and other luminous extraterrestrial systems via non-gravitational signatures. The dark matter field, which makes up a defect, may interact with standard model particles, including quarks and the photon, resulting in the alteration of their masses. When a topological defect passes through a pulsar, its mass, radius and internal structure may be altered, resulting in a pulsar `quake'. A topological defect may also function as a cosmic dielectric material with a distinctive frequency-dependent index of refraction, which would give rise to the time delay of a periodic extraterrestrial light or radio signal, and the dispersion of a light or radio source in a manner distinct to a gravitational lens. A topological defect passing through Earth may give rise to temporary non-zero electric dipole moments for an electron, proton, neutron, nuclei and atoms. The biggest advantage of such astrophysical observations over recently proposed terrestrial detection methods is the much higher probability of a defect been found in the vast volumes of outer space compared with one passing through Earth itself.

description: The IVGDR in 208Pb has been measured with high energy resolution with the (p,p') reaction under extreme forward angles and shows considerable fine structure. Characteristic scales are extracted from the spectra with a wavelet analysis based on continuous wavelet transforms. Comparison with corresponding analyses of B(E1) strength distributions from microscopic model calculations in the framework of the QPM and relativistic RPA allow to identify giant resonance decay mechanisms responsible for the fine structure. The level density of 1- states can be related to local fluctuations of the cross sections in the energy region of the IVGDR. The magnitude of the fluctuations is determined by the autocorrelation function. Scales in the fine structure of the IVGDR in 208Pb are found at 80, 130, 220, 430, 640, 960 keV, and at 1.75 MeV. The values of the most prominent scales can be reasonably well reproduced by the microscopic calculations although they generally yield a smaller number of scales. In both models the major scales are already present at the one-particle one-hole level indicating Landau damping as a dominant mechanism responsible for the fine structure of the IVGDR in contrast to the isoscalar giant quadrupole resonance, where fine structure arises from the coupling to low-lying surface vibrations. The inclusion of complex configurations in the calculations changes the E1 strength distributions but the impact on the wavelet power spectra and characteristic scales is limited. The level density of 1- states is extracted in the excitation energy range 9-12.5 MeV and compared to a variety of phenomenological and microscopic models. The back-shifted Fermi gas model parameterization of Rauscher et al., Phys. Rev. C 56, 1613 (1997) describes the level-density data well, while other phenomeological and microscopic approaches fail to reproduce absolute values or the energy dependence or both.

description: A configuration space approach is developed to uncover generic stability peculiarities for the lowest energy neutral and charged exciton complexes (biexciton and trion) in quasi-one-dimensional semiconductors. Trions are shown to be more stable than biexcitons in strongly confined structures with small reduced electron-hole masses. Biexcitons are more stable in less confined structures with large reduced electron-hole masses. In semiconducting carbon nanotubes, in particular, the trion binding energy is shown to be greater than that of the biexciton by a factor ~1.4 decreasing with diameter, thus revealing the general physical principles that underlie recent experimental observations.

description: We describe a Casimir setup consisting of two aligned sinusoidally corrugated Ni surfaces, one of which is "hidden" by a thin opaque layer of gold with a flat exposed surface. The gold layer acts as a low-pass filter that allows for a clean observation of the controversial thermal Casimir force between the corrugations, with currently available Casimir apparatuses. The proposed scheme of measurement, based on the phase-dependent modulation of the Casimir force, requires no electrostatic calibrations of the apparatus, and is unaffected by uncertainties in the knowledge of the optical properties of the surfaces. This scheme should allow for an unambiguous discrimination between alternative theoretical prescriptions that have been proposed in the literature for the thermal Casimir effect.

We consider the simplest case of one abelian factor (Mordell-Weil rank one) and investigate the conditions that are induced on the coefficients of its Tate form. Converting the equation representing the generic hypersurface $P_{112}$ to this Tate's form we find that the presence of a U(1), already in this local description, is consistent with the exceptional ${\cal E}_6$ and ${\cal E}_7$ non-abelian singularities. We briefly comment on a viable ${\cal E}_6\times U(1)$ effective F-theory model.

We construct several variants of one-parameter double-hybrid approximations using the Tao-Perdew-Staroverov-Scuseria (TPSS) meta-GGA functional and test them on test sets of atomization energies and reaction barrier heights. The most accurate variant uses the uniform coordinate scaling of the density and of the kinetic energy density in the correlation functional, and improves over both standard Kohn-Sham TPSS and second-order Moller-Plesset calculations.

description: The Abelian semigroup expansion is a powerful and simple method to derive new Lie algebras from a given one. Recently it was shown that the $S$-expansion of $\mathfrak{so}\left( 3,2\right) $ leads us to the Maxwell algebra $\mathcal{M}$. In this paper we extend this result to superalgebras, by proving that different choices of abelian semigroups $S$ lead to interesting $D=4$ Maxwell Superalgebras. In particular, the minimal Maxwell superalgebra $s\mathcal{M}$ and the $N$-extended Maxwell superalgebra $s\mathcal{M}^{\left( N\right) }$ recently found by the Maurer Cartan expansion procedure, are derived alternatively as an $S$-expansion of $\mathfrak{osp}\left( 4|N\right) $. Moreover we show that new minimal Maxwell superalgebras type $s\mathcal{M}_{m+2}$ and their $N$-extended generalization can be obtained using the $S$-expansion procedure.

description: The new challenges posed by the need of finding strong rare-earth free magnets demand methods that can predict magnetization and magnetocrystalline anisotropy energy (MAE). We argue that correlated electron effects, which are normally underestimated in band structure calculations, play a crucial role in the development of the orbital component of the magnetic moments. Because magnetic anisotropy arises from this orbital component, the ability to include correlation effects has profound consequences on our predictive power of the MAE of strong magnets. Here we show that incorporating the local effects of electronic correlations with dynamical mean-field theory provides reliable estimates of the orbital moment, the mass enhancement and the MAE of YCo5.

description: Los desarrollos en inteligencia artificial avanzada (AI) han sido espectaculares en los últimos dos años, mejorando la integración de sensores electrónicos, investigación robótica, algoritmos avanzados y un aumento imporatnte en la potencia de cálculo. En varios casos los equipos de ingenieros han conseguido diseños que mostraron niveles cercanos a las habilidades de los seres humanos en tareas complejas, incluso superiores en otras más especializadas pero exigentes, lo que hace verosimil la prospectiva de rendimientos superiores a los del ser humano, y en tareas cada vez más generales, en las próximas décadas. El análisis del impacto social de estas tecnologías no puede dejar al margen los usos potenciales de la IA con fines militares, incluyendo su uso como herramienta de apoyo en las labores de los servicios de inteligencia y en la defensa o estrategia militar. Esta comunicación analiza algunos riesgos específicos que plantea el empleo de robots letales autónomos (LAR) dotados de IA avanzada, y se indican algunos aspectos que requieren un tratamiento detenido en un debate público y bien informado, dado el débil marco de gobernanza internacional en el que se desarrollan los intentos de regular el uso de UAV (vehículos aéreos no tripulados) y otras armas avanzadas.

Developments in advance Artificial Intelligence (AI) have been spectacular in the last 2 years, with a better integration of electronic sensors, research in robotics, advanced algorithms and increased computing power. Many of them showed efficiency levels close to humans skills in some specialized, but complex tasks, which makes plausible the prospective of superhuman perfomance in the next decades. The social impact analysis would be incomplete without considering potential uses of AI for military purposes, including assitance to intelligence services and defense or military strategy. Specific risks associated with the design of autonomous letal robots (LAR) with advanced AI should be carefully considered in a public and well-informed debate, given the weak governance framework in which eventual regulations at international level for defense and military response using drones or advance weapons could be approached.

description: By numerical and analytical methods, we study in detail the effects of the Lifshitz dynamical exponent $z$ on the vector condensate induced by an applied magnetic field in the probe limit. Concretely, in the presence of the magnetic field, we obtain the Landau level independent of $z$, and also find the critical value by coupling a Maxwell complex vector field and SU(2) field into a (3+1)-dimensional Lifshitz black hole, respectively. The research results show that for both two models with the lowest Landau level, the increasing $z$ improves the response of the critical temperature to the applied magnetic field even without the charge density, and the analytical results uphold the numerical results. In addition, we find even in the Lifshitz black hole, the Maxwell complex vector model is still a generalization of the SU(2) Yang-Mills model. Furthermore, we construct the square vortex lattice and discuss the implications of these results.

description: We argued that deep inelastic scattering (DIS) at small values of Q squared is an essentially nonperturbative process and can be described, partially at least, by the vector meson dominance (VMD) model. We showed by the straightforward calculation that VMD model alone can successfully explain data on structure functions of DIS in a broad interval of x (5e-2 - 1e-4) for the region Q squared < 1 GeV squared. For a description of data at larger Q squared we used the two-component (VMD + perturbative QCD) approach. We showed that these two components can be separated if VMD is used in the aligned jet version. We took into account, in calculations of VMD component of structure functions, the excited states of the rho-meson and nondiagonal transitions between different members of the rho-meson family. Amplitudes of these transitions were obtained using a formalism of the light-front Bethe-Salpeter equation and the method of diffraction-scattering eigenstates. The perturbative QCD component was calculated using a framework of the colour dipole model with the dipole cross section having a Regge-type energy dependence. We presented results of the detailed comparison of our predictions with experimental data for structure functions of the nucleon. We obtained also approximate predictions for the structure functions in the region of very small x, up to 1e-9, and showed that nonperturbative component at such values of x is still relatively large and must be taken into account if Q squared is about few GeV squared or less.

description: Herbomineral formulations have increased in recognition and popularity due to their high safety and better therapeutic action. A new proprietary herbomineral formulation was formulated with a mixture of the herbal root extract of ashwagandha and three minerals viz. zinc, magnesium, and selenium. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the test formulation when applied to splenocyte cells isolated from the Biofield Treated mice. The test formulation was divided into two parts. One part was denoted as the control without any Biofield Energy Treatment. The other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely by seven renowned Biofield Energy Healers. A wide concentration range (0.00001053 to 10.53 µg/mL) of the test formulation was used to determine non-cytotoxic concentrations using MTT assay. Further, the expression of pro-inflammatory cytokines (TNF-α, MIP-1α, and IL-1β) was determined by ELISA method. The test formulation was evaluated and found to be safe up to 1.053 µg/mL with a percentage cell viability range of 73% to 97% using MTT assay. The Biofield Treated formulation improved the cell viability up to 6.61% compared with the untreated test formulation. TNF-α expression was significantly inhibited by 16.72% at 0.1053 µg/mL compared with the untreated test formulation, however expression was significantly altered by 53.67% and 25.62% at 0.01053 and 1.053 µg/mL, respectively compared to the untreated test formulation. TNF-α expression was also suppressed in the Biofield Treated test formulation at 0.001053 and 0.1053 µg/mL by 4.0% and 8.56%, respectively as compared with the vehicle control. MIP-1α suppression was reported in the Biofield Treated test formulation at 0.00001053 to 1.053 µg/mL by 8.43%, 22.02%, 21.92%, 20.54%, 5.40%, and 19.82%, respectively compared with the vehicle control. However, the Biofield Treated formulation further exhibited substantial suppression of MIP-1α at 0.0001053, 0.001053, 0.01053, and 0.1053 µg/mL by 13.50%, 7.38%, 36.83% (p≤0.001), and 2.53%, respectively compared with the untreated test formulation. In addition, significant inhibition of IL-1β secretion was reported in the Biofield Treated formulation at 0.0001053, 0.001053, 0.01053, and 0.01053 µg/mL by 32.40%, 14.99%, 60.42%, and 15.15%, respectively compared with the untreated test formulation. The Biofield Energy Healing Treatment significantly potentiated the immunosuppressive effect of the test formulation in Biofield Treated mouse splenocytes, which can be used for autoimmune and inflammatory diseases, stress management and anti-aging by improving overall health.

description: The use of herbomineral formulations in the healthcare sector has increased due to their high safety and better therapeutic action. A new proprietary herbomineral formulation was formulated with a mixture of the herbal root extract of ashwagandha and three minerals viz. zinc chloride, magnesium gluconate, and sodium selenate. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the formulation when applied to splenocyte cells isolated from mice spleen. The formulation was divided into two parts; one was the control without any Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received Biofield Energy Healing Treatment remotely by seven renowned Biofield Energy Healers. The test formulation was evaluated to find the expression of pro-inflammatory cytokines such as TNF-α, MIP-1α, and IL-1β along with non-cytotoxic concentrations by MTT assay. The splenocytes were given the Biofield Energy Treated and untreated sample at concentrations range (0.00001053 to 10.53 µg/mL) for 48 hours and was reported with safe concentration up to 1.053 µg/mL with percentage viability range from 76.7% to 109.2% in both samples. Biofield Energy Healing significantly enhanced the cell viability as compared with the untreated formulation. The expression of TNF-α was significantly inhibited in the Biofield Treated formulation at 0.01053, 0.1053, and 1.053 µg/mL by 1.77%, 1.93%, and 3.55%, respectively compared with the untreated formulation. The rest of the tested concentrations of the Biofield Treated formulation showed an increase in TNF-α expression at 0.00001053, 0.0001053, and 0.001053 µg/mL by 7.26%, 8.50%, and 8.50%, respectively compared to the vehicle control group. Similarly, the MIP-1α expression was inhibited by the Biofield Energy Treated formulation and showed immunosuppression activity at 0.01053 µg/mL by 18.47% (p≤0.001) compared to the untreated formulation. MIP-1α expression was reported as 628.94 ± 13.0 pg/mL in the untreated formulation, while it decreased to 512.74 ± 1.9 pg/mL in the Biofield Treated formulation at 0.01053 µg/mL. In addition, the IL-1β secretion was also significantly inhibited by the Biofield Treated formulation at concentrations 0.001053, 0.01053, 0.1053, and 1.053 µg/mL by 72.02%, 50.16%, 30.68%, and 22.11%, respectively as compared with the untreated formulation. Overall, The Trivedi Effect® significantly down-regulated the pro-inflammatory cytokines and potentiated the immunosuppressive effect of the treated formulation, which can be better utilized in organ transplants, anti-aging, stress management, autoimmune disorders, and inflammatory disorders, etc. to modulate the immune system by improving overall health.

description: The AM Canum Venaticorum (AM CVn) binaries are a rare group of ultra-short period, mass-transferring white dwarf binaries, some of which may be Type Ia supernova progenitors. More than a third of the total known population of AM CVn binaries have been discovered via the Sloan Digital Sky Survey (SDSS). Here, we discuss our search for new AM CVns in the SDSS spectroscopic data base, and present two new AM CVns discovered in SDSS-III spectroscopy, SDSS J113732.32+405458.3 and SDSS J150551.58+065948.7. The AM CVn binaries exhibit a connection between their spectral appearance and their orbital period, the spectra of these two new AM CVns suggest that they may be long period systems. Using the radial velocity variations of the emission lines, we measure a possible orbital period of 59.6 +/- 2.7 minutes for SDSS J113732.32+405458.3. Since our search of SDSS spectroscopy has revealed only these two new systems, it is unlikely that a large population of AM CVn binaries have been missed, and their discovery should have little effect on previous calculations of the AM CVn space density.

description: Quercus suberon tyypillinen puulaji Välimeren maissa. Se kasvaa luonnonvaraisena Etelä-Euroopassa ja Pohjois-Afrikassa, joissa kesät ovat kuivia ja talvet lauhoja (http://www.discoverlife.org). Tämä ikivihreä laji kasvaa 20 metriseksi ja sen ympärysmitta voi olla yli 2 m. Korkkitammen kuoreen muodostuu paksu kerros huokoista, uurteista korkkia, jonka paksuus voi olla 20 cm. Lehdet voivat olla olla heikosti liuskoittuneet tai 4-7 kertaisesti hammaslaitaiset. Vaikka laji voi kasvaa eri tyyppissä maissa (pH 5-7) se suosii hapanta eikä kestä kalkkia tai suolaisia olosuhteita. Iberian niemimaalla korkkitammialueet ovat tärkeitä monille uhanalaisille eläimille. Samalla kun puiden ympärillä kasvatetaan viljaa ja laidunnetaan karjaa rungoista kerätään korkkia 10-12 vuoden välein. Portugali on suurin korkintuottaja- ja viejämaa, joka viljelee korkkitammia teollisuutta varten.
The local and global geometrical aspects of the twin paradox in static spacetimes: I. Three spherically symmetric spacetimes

description: We investigate local and global properties of timelike geodesics in three static spherically symmetric spacetimes. These properties are of its own mathematical relevance and provide a solution of the physical `twin paradox' problem. The latter means that we focus our studies on the search of the longest timelike geodesics between two given points. Due to problems with solving the geodesic deviation equation we restrict our investigations to radial and circular (if exist) geodesics. On these curves we find general Jacobi vector fields, determine by means of them sequences of conjugate points and with the aid of the comoving coordinate system and the spherical symmetry we determine the cut points. These notions identify segments of radial and circular gepdesics which are locally or globally of maximal length. In de Sitter spacetime all geodesics are globally maximal. In CAdS and Bertotti--Robinson spacetimes the radial geodesics which infinitely many times oscillate between antipodal points in the space contain infinite number of equally separated conjugate points and there are no other cut points. Yet in these two spacetimes each outgoing or ingoing radial geodesic which does not cross the centre is globally of maximal length. Circular geodesics exist only in CAdS spacetime and contain an infinite sequence of equally separated conjugate points. The geodesic curves which intersect the circular ones at these points may either belong to the two-surface $θ=π/2$ or lie outside it.

Elektronische und optische Eigenschaften von Alkaliniobaten berechnet innerhalb der Dichtefunktionaltheorie
Creators: name: Schmidt, Falko
Publisher: name: Universität Paderborn
Year: 2023

description: In dieser Arbeit sollen die Ferroelektrika Kaliumniobat und Lithiumniobat innerhalb der Dichtefunktionaltheorie und darauf aufbauender Methoden untersucht werden. Der Fokus liegt dabei auf Polaronen in Lithiumniobat, also Zusatzladungen, die durch eine Gitterverzerrung auf zu bestimmende Punkte im Kristall lokalisiert werden. Dazu werden verschiedene Punktdefekte betrachtet, die als möglicher Ausgangspunkt in Betracht kommen. Neben dem Nb_Li Antisite und der V_Li Lithiumvakanz, welche in der Literatur hinreichend beschrieben werden, soll auch das Nb_V-V_Li Defektpaar betrachtet werden. Nach einer gründlichen Strukturoptimierung beider Materialien wird eine Vielzahl an Methoden angewendet, um im Vergleich mit dem Experiment aussichtsreiche Kandidaten zu identifizieren. Dazu zählen Ladungsdichten, Zustandsdichten, Bandstrukturen, Bindungsenergien, Bildungsenergien und Energiebarrieren. Ein besonderes Augenmerk liegt auf der Berechnung der dielektrischen Funktion, welche die Ableitung verschiedener optischer Größen erlaubt. Die an sich zu kleine Bandlücke aus der Dichtefunktionaltheorie wird durch Quasiteilchenverschiebungen aus einer GW-Rechnung verbreitert, während exzitonische und Lokalfeldeffekte durch das Lösen der Bethe-Salpeter-Gleichung eingebunden werden. Für Kaliumniobat, welches ohne Defekte modelliert wird, konnten zusätzlich zu den bereits genannten Methoden auch einige Rechnungen zur nichtlinearen Optik durchgeführt werden.
description: In this work, the ferroelectrica potassium niobate and lithium niobate shall be examined within density-functional theory and advanced methods. The focus lies in polarons in lithium niobate, additional charges bound to certain points within the crystal, which need to be determined, by a lattice relaxation. To this end, different point defects that could be the basis are investigated. Beyond the Nb_Li antisite and the V_Li lithium vacancy, which are sufficiently covered in literature, the Nb_V-V_Li defect pair shall be examined. After a thorough structural optimization of both materials, a multitude of methods is applied to identify promising candidates by comparison to experimental data. This includes charge densities, densities of states, band structures, binding energies, formation energies, and energy barriers. Special attention is given to the calculation of the dielectric function that allows for the deduction of different optical properties. The inherently underestimated band gap from density-functional theory is widened by quasiparticle shifts from a GW calculation, while excitonic and local-field effects are included by solving the Bethe-Salpeter equation. For potassium niobate, which is modelled without defects, nonlinear optical calculations could be performed in addition to the mentioned methods.
