description: In singlet two-electron systems the natural occupation numbers of the one-particle reduced density matrix are given as squares of the natural amplitudes which are defined as the expansion coefficients of the two-electron wave function in a natural orbital basis. In this work we relate the sign of the natural amplitudes to the nature of the two-body interaction. We show that long-range Coulomb-type interactions are responsible for the appearance of positive amplitudes and give both analytical and numerical examples that illustrate how the long-distance structure of the wave function affects these amplitudes. We further demonstrate that the amplitudes show an avoided crossing behavior as function of a parameter in the Hamiltonian and use this feature to show that these amplitudes never become zero, except for special interactions in which infinitely many of them can become zero simultaneously when changing the interaction strength. This mechanism of avoided crossings provides an alternative argument for the non-vanishing of the natural occupation numbers in Coulomb systems.

description: We study the formation and evolution of a failed filament eruption observed in NOAA active region 11121 near the southeast limb on November 6, 2010. We use a time series of SDO/AIA 304, 171, 131, 193, 335, 94 Å images, SDO/HMI magnetograms, plus ROSA and ISOON Hαimages, to study the erupting active region. We identify coronal loop arcades associated with a quadrupolar magnetic configuration, and show that the expansion and cancelation of the central loop arcade system over the filament is followed by the eruption of the filament. The erupting filament reveals a clear helical twist and develops a same sign of writhe in the form of inverse γ-shape. The observations support the "magnetic breakout" process with the eruption been triggered by quadrupolar reconnection in the corona. We suggest that the formation mechanism of the inverse γ-shape flux rope may be the MHD helical kink instability. The eruption has failed due to the large-scale, closed, overlying magnetic loop arcade that encloses the active region.

description: The aim of this study is to determine cyber bullying, cyber victimization, cyber sensitivity, and virtual loneliness of students and their relationships. The study was designed with descriptive and relational model within the framework of quantitative research method. The sample of the study consists of 208 university students. In order to collect data, 4 different scales were used and correlations between descriptive statistics of the scales and the scale scores were employed. Accordingly, especially when the students' scores on the sensitivity scale related to cyber bullying increase, the scores they receive from the e-bullying scale and virtual sharing dimension of the virtual media loneliness scale decrease, which is remarkable.

description: The invariants in half-maximal supergravity theories in D=4,5 are discussed in detail up to dimension eight (e.g. R^4). In D=4, owing to the anomaly in the rigid SL(2,R) duality symmetry, the restrictions on divergences need careful treatment. In pure N=4 supergravity, this anomalous symmetry still implies duality invariance of candidate counterterms at three loops. Provided one makes the additional assumption that there exists a full 16-supercharge off-shell formulation of the theory, counterterms at L>1 loops would also have to be writable as full-superspace integrals. At the three-loop order such a duality-invariant full-superspace integral candidate counterterm exists, but its duality invariance is marginal in the sense that the full-superspace counter-Lagrangian is not itself duality-invariant. We show that such marginal invariants are not allowable as counterterms in a 16-supercharge off-shell formalism. It is not possible to draw the same conclusion when vector multiplets are present because of the appearance of F^4 terms in the SL(2,R) anomaly. In D=5 there is no one-loop anomaly in the shift invariance of the dilaton, and we argue that this implies finiteness at two loops, again subject to the assumption that 16 supercharges can be preserved off-shell.

description: In the derivation of Holographic Dark Energy (HDE), the area law of the black hole entropy assumes a crucial role. However, the entropy-area relation can be modified including some quantum effects, motivated from the Loop Quantum Gravity (LQG), string theory and black hole physics. In this paper, we study the cosmological implications of the interacting logarithmic entropy-corrected HDE (LECHDE) model in the framework of Brans-Dicke (BD) cosmology. As system's infrared (IR) cut-off, we choose the average radius of Ricci scalar curvature, i.e. $R^{-1/2}$. We obtain the Equation of State (EoS) parameter $ω_D$, the deceleration parameter $q$ and the evolution of energy density parameter $Ω'_D$ of our model in a non-flat universe. Moreover, we study the limiting cases corresponding to our model without corrections and to the Einstein's gravity.

title: Der Gegensatz von Information ist nicht unbedingt Desinformation und manchmal ist Langeweile ein Weg zur Unterhaltung

description: „Der  Gegensatz  von  Information  ist  Desinformation,  der  Gegensatz  von  Unterhaltung  ist Langeweile“lautete  ein  1996  erstmals  erschienener  und  oft  zitierter  Diskussionsbeitrag. Kann dieses Statement auch heute noch so abgegeben werden? Die Antwort darauf fällt differenziert  aus,  weil  die  grundsätzliche  Aussage,  dass  Information  und  Unterhaltung  keine Gegensätze sind, sondern unterschiedliche Aspekte des Medien-und Kommunikationsprozesses  fokussieren,  nach  wie  vor  stimmt  und  heute  in  Wissenschaft  und  Kommunikationsforschung weitgehend anerkannt ist. Allerdings, so argumentiert die Verfasserin mit Blick auf Reality TV und „Quality TV“, hat sich der Dualismus insofern nur verschoben als die Tren-nung in „gute“ versus „schlechte“ Unterhaltung eine ähnliche Distinktionsfunktion erfüllt. Die gesellschaftlichen wie medialen Wandlungsprozesse, insbesondere die digital vernetzten Medien, haben weitere Veränderungen bewirkt, die sowohl die Information als auch die Unterhaltung betreffen und letztlich zu einer Modifikation des damaligen titelgebenden Statements führe

description: We study conformal field theory with the symmetry algebra $\mathcal{A}(2,p)=\hat{\mathfrak{gl}}(n)_{2}/\hat{\mathfrak{gl}}(n-p)_2$. In order to support the conjecture that this algebra acts on the moduli space of instantons on $\mathbb{C}^{2}/\mathbb{Z}_{p}$, we calculate the characters of its representations and check their coincidence with the generating functions of the fixed points of the moduli space of instantons. We show that the algebra $\mathcal{A}(2,p)$ can be realized in two ways. The first realization is connected with the cross-product of $p$ Virasoro and $p$ Heisenberg algebras: $\mathcal{H}^{p}\times \textrm{Vir}^{p}$. The second realization is connected with: $\mathcal{H}^{p}\times \hat{\mathfrak{sl}}(p)_2\times (\hat{\mathfrak{sl}}(2)_p \times \hat{\mathfrak{sl}}(2)_{n-p}/\hat{\mathfrak{sl}}(2)_n)$. The equivalence of these two realizations provides the non-trivial identity for the characters of $\mathcal{A}(2,p)$. The moduli space of instantons on $\mathbb{C}^{2}/\mathbb{Z}_{p}$ admits two different compactifications. This leads to two different bases for the representations of $\mathcal{A}(2,p)$. We use this fact to explain the existence of two forms of the instanton pure partition functions.

description: We report on room temperature magnetoresistance and low frequency noise in sub-100nm elliptic CoFeB/MgO/CoFeB magnetic tunnel junctions with ultrathin (0.9nm) barriers. For magnetic fields applied along the hard axis, we observe current induced magnetization switching between the antiparallel and parallel alignments at DC current densities as low as 4*106A/cm2. We attribute the low value of the critical current to the influence of localized reductions in the tunnel barrier, which affects the current distribution. The analysis of random telegraph noise, which appears in the field interval near a magnetization switch, provides an estimate to the dimension of the pseudo pinholes that trigger the magnetization switching via local spin torque. Micromagnetic simulations qualitatively and quantitatively reproduce the main experimental observations.
The Brown-York mass of black holes in Warped Anti-de Sitter space

description: We give a direct computation of the mass of black holes in Warped Anti-de Sitter space (WAdS) in terms of the Brown-York stress-tensor at the boundary. This permits to explore to what extent the holographic renormalization techniques can be applied to such type of deformation of AdS. We show that, despite some components of the boundary stress-tensor diverge and resist to be regularized by the introduction of local counterterms, the precise combination that gives the quasilocal energy density yields a finite integral. The result turns out to be in agreement with previous computations of the black hole mass obtained with different approaches. This is seen to happen both in the case of Topologically Massive Gravity and of the so-called New Massive Gravity. Here, we focus our attention on the latter. We observe that, despite other conserved charges diverge in the near boundary limit, the finite part in the large radius expansion captures the physically relevant contribution. We compute the black hole angular momentum in this way and we obtain a result that is in perfect agreement with previous calculations.

description: \textbf{Chapter 1}\\ This paper explores the implications of the mismatch hypothesis in the context of the labor market using a survey on newly licensed US lawyers called the After the JD Study. Using a triple difference approach, I measure the impact of diversity quotas on marginal minority workers’ future salaries, promotion rates, and leaving rates for occupation and job. With middling statistical power, my findings are in line with the mismatch hypothesis in that beneficiaries of the diversity quota policy are made ex-ante worse off. My findings are also in line with recent literature on diminishing racial outcome gaps by skill.
 \textbf{Chapter 2}\\ In this paper, we provide theoretical framework for three models of Digital Media Firm behavior called \textit{Premium}, \textit{Free-to-Play}, and \textit{Play-to-Earn} as well as suggest an empirical measure of firm ponzi-likeness. First, we study a baseline model optimal price and quality of a digital product, the premium model. Second, we extend the baseline model where some customers, called minnows, receive the product for free and other customers, called whales, pay a price for a better version of the product, this is the free-to-play model. Finally, we explore a model where customers receive a security-like asset from the firm and this asset acts like a negative price while also subsidizing the firm's revenue. This final model provides an environment for much research. We show that, even when firms are ponzi-schemes in this final model, quality of the product need not be at a minimum. We also briefly discuss how one would measure the ponzi-likeness of a digital media firm in the third model setting.
 \textbf{Chapter 3}\\ In this paper, I explore unique measures of racial prejudice and their impact on black wages in the labor market using the General Social Survey, Current Population Survey and the NLSY79. I generate two variables to proxy for racial prejudice which are extracted from the GSS and the NLSY79. The first variable, drawn from the GSS, measures prejudice sentiment towards blacks and the second, drawn from the NLSY79, measures individual experience with racial discrimination. I use these measurements to proxy for racial prejudice and its impact on the black-white wage gap. I find that these variables are two distinctly different measures of racial discrimination in the labor market, providing a powerful instrument for measuring racial discrimination in the labor market. They also provide the insight that, while racial prejudice may be high in certain occupations and regions, this sentiment does not directly impact black outcomes. Specifically, wages are more sensitive to racial prejudice in WC jobs than in BC jobs.

description: Newcastle Disease Virus (NDV) has oncolytic activity and has been promoting as a virotherapy agent. The objective of this study was to evaluate the potency of NDV Tabanan-1/ARP/2017 as a virotherapy agent. This study was used the white rat Rattus norvegicus as an animal fibrosarcoma model. Benzo(a)pyrene solution at 0.3% (w/v) was used to induce fibrosarcoma. After fibrosarcoma appeared, rats were treated as follows: Rats in group P0 were injected with 0.5 mL phosphate buffer saline (PBS), while those in group P1 were injected with the ND virus, intratumorally at a dose of 0.5 mL of 29 HA titer of NDV Tabanan-1/ARP/2017. The dynamic of tumor growth was evaluated. Upon the starting point of the treatment, the mean volume of rat tumors mass of P0 and P1 were 1,769.83±1,103.58 mm3 and 1,194.29±592.82 mm3, respectively. At the end of the treatment, the mean tumor volume of P0 was 8,549.38±5,347.51 mm3, while at P1 was 3,848.25 ± 3,539,189 mm3. From the observation of microscopic images, it was found that the number of blood vessels at P1 was 44.67±19.348, significantly lower (p<0.05) than that of the P0 (121.33±34.530). From this study, it can be concluded that virotherapy with NDV-Tabanan-1/ARP/2017, can inhibit fibrosarcoma growth and reduce the number of blood vessel in the tumor. The effectiveness of Tabanan-1/ARP/2017 as a virotherapy agent is discussed.

description: The chemically peculiar B star $ϕ$ Phe was, until very recently, considered a triple system, even though the data were not conclusive and the orbits rather uncertain. Very recent results by Korhonen et al. (2013) provided a revised orbit, different from the then available astrometric Hipparcos orbit. Additional spectroscopic data, obtained with the BESO spectrograph at Cerro Armazones, confirm the newly found orbit, even though the resulting radial velocities do not allow to improve on the recent orbit. We combine the latter with the Hipparcos measurements to secure the astrometric orbit, and derive the inclination of the system. Using evolutionary tracks, we can finally constrain all the parameters of the two components in this system. We confirm the mass of the primary, 3 M$_\odot$, and find that the companion has a mass of 0.9 M$_\odot$. The inclination of the system is $i=93^{\circ} \pm 4.7^{\circ}$, and is potentially eclipsing; we predict the time of the next conjunction. Given that the eccentricity of the orbit and the exact value of the semi-amplitude of the radial velocity relies on just one set of points, we also urge observers to measure radial velocities at the next periastron passage in April 2015.

description: Models of natural supersymmetry seek to solve the little hierarchy problem by positing a spectrum of light higgsinos m_0 leads to automatic cancellations during renormalization group (RG) running, and to radiatively-induced low fine-tuning at the electroweak scale. Coupled with large mixing in the top squark sector, RNS allows for fine-tuning at the 3-10% level with TeV-scale top squarks and a 125 GeV light Higgs scalar h. The model allows for at least a partial solution to the SUSY flavor, CP and gravitino problems since first/second generation scalars (and the gravitino) may exist in the 10-30 TeV regime. We outline some possible signatures for RNS at the LHC and at a linear e^+e^- collider. If the strong CP problem is solved by the Peccei-Quinn mechanism, then RNS naturally accommodates mixed axion-higgsino cold dark matter, where the light higgsino-like WIMPS - which in this case make up only a fraction of the measured relic abundance - should be detectable at upcoming WIMP detectors.

description: The collision smearing of the nucleon momenta about their initial values during relativistic nucleus-nucleus collisions is investigated. To a certain degree, our model belongs to the transport type, and we investigate the evolution of the nucleon system created at a nucleus-nucleus collision. However, we parameterize this development by the number of collisions of every particle during evolution rather than by the time variable. It is assumed that the group of nucleons which leave the system after the same number of collisions can be joined in a particular statistical ensemble. The nucleon nonequilibrium distribution functions, which depend on a certain number of collisions of a nucleon before freeze-out, are derived.

description: Bright AGN frequently show ultra-fast outflows (UFOs) with outflow velocities vout ~0.1c. These outflows may be the source of AGN feedback on their host galaxies sought by galaxy formation modellers. The exact effect of the outflows on the ambient galaxy gas strongly depends on whether the shocked UFOs cool rapidly or not. This in turn depends on whether the shocked electrons share the same temperature as ions (one temperature regime; 1T) or decouple (2T), as has been recently suggested. Here we calculate the Inverse Compton spectrum emitted by such shocks, finding a broad feature potentially detectable either in mid-to-high energy X-rays (1T case) or only in the soft X-rays (2T). We argue that current observations of AGN do not seem to show evidence for the 1T component. The limits on the 2T emission are far weaker, and in fact it is possible that the observed soft X-ray excess of AGN is partially or fully due to the 2T shock emission. This suggests that UFOs are in the energy-driven regime outside the central few pc, and must pump considerable amounts of not only momentum but also energy into the ambient gas. We encourage X-ray observers to look for the Inverse Compton components calculated here in order to constrain AGN feedback models further.

description: We report on the anomalously high line strength of a single rotational level in the ultracold photoassociation of two 85Rb atoms to form 85Rb2. The v' = 111, J' = 5 level belongs to the Hund's case (c) 2 (0g+) state, which correlates to the Hund's case (a) 2 1 Σg+ state. Its strength is caused by coupling with a very near-resonant long-range state. The long-range component is the energetically degenerate v' = 155, J' = 5 level of the case (c) 2 (1g)$ state, correlating to the case (a) 1 1 Πg state. The line strength is enhanced by an order of magnitude through this coupling, relative to nearby vibrational levels and even to nearby rotational levels of the same vibrational level. This enhancement is in addition to the enhancement seen in all J' = 3 and 5 levels of the 2 (0g+) state due to an l = 4 shape resonance in the a 3 Σu+ state continuum, which alters the distribution of levels formed by photoassociation.

description: The aim of this study is to reveal the effect of using two different learning environments, namely a “learning environment enriched with concrete models and computer-aided learning environment” and “traditional and computer-aided learning environment” and their effects on students’ Geometric Object Subject achievement levels. For this purpose, a mixed research method was used in which qualitative and quantitative research methods were applied together. It was found that the achievement levels of the students were positively affected in both experimental groups, but the students' achievement in geometric objects was higher in the experimental group in which computer-assisted teaching environment and enriched teaching applications were used in combination.

description: We study quantum critical behavior in three dimensional lattice Gross-Neveu models containing two massless Dirac fermions. We focus on two models with SU(2) flavor symmetry and either a $Z_2$ or a U(1) chiral symmetry. Both models could not be studied earlier due to sign problems. We use the fermion bag approach which is free of sign problems and compute critical exponents at the phase transitions. We estimate $ν= 0.83(1)$, $η= 0.62(1)$, $η_ψ= 0.38(1)$ in the $Z_2$ and $ν= 0.849(8)$, $η= 0.633(8)$, $η_ψ= 0.373(3)$ in the U(1) model.

description: We propose a modified $χ^β$-divergence, give some of its properties, and show that this leads to the definition of a generalized Fisher information. We give generalized Cramér-Rao inequalities, involving this Fisher information, an extension of the Fisher information matrix, and arbitrary norms and power of the estimation error. In the case of a location parameter, we obtain new characterizations of the generalized $q$-Gaussians, for instance as the distribution with a given moment that minimizes the generalized Fisher information. Finally we indicate how the generalized Fisher information can lead to new uncertainty relations.

description: The choice of appropriate interaction models is among the major disadvantages of conventional methods such as molecular dynamics and Monte Carlo simulations. On the other hand, the so-called reverse Monte Carlo (RMC) method, based on experimental data, can be applied without any interatomic and/or intermolecular interactions. The RMC results are accompanied by artificial satellite peaks. To remedy this problem, we use an extension of the RMC algorithm, which introduces an energy penalty term into the acceptance criteria. This method is referred to as the hybrid reverse Monte Carlo (HRMC) method. The idea of this paper is to test the validity of a combined potential model of coulomb and Lennard-Jones in a fluoride glass system BaMnMF_{7} (M=Fe,V) using HRMC method. The results show a good agreement between experimental and calculated characteristics, as well as a meaningful improvement in partial pair distribution functions. We suggest that this model should be used in calculating the structural properties and in describing the average correlations between components of fluoride glass or a similar system. We also suggest that HRMC could be useful as a tool for testing the interaction potential models, as well as for conventional applications.

description: We calculate the axial current decay constants of taste non-Goldstone pions and kaons in staggered chiral perturbation theory through next-to-leading order. The results are a simple generalization of the results for the taste Goldstone case. New low-energy couplings are limited to analytic corrections that vanish in the continuum limit; certain coefficients of the chiral logarithms are modified, but they contain no new couplings. We report results for quenched, fully dynamical, and partially quenched cases of interest in the chiral SU(3) and SU(2) theories.

Coevolution (Or Not) of Supermassive Black Holes and Host Galaxies

description: We review the observed demographics and inferred evolution of supermassive black holes (BHs) found by dynamical modeling of spatially resolved kinematics. Most influential was the discovery of a tight correlation between BH mass and the velocity dispersion of the host-galaxy bulge. It and other correlations led to the belief that BHs and bulges coevolve by regulating each other's growth. New results are now replacing this simple story with a richer and more plausible picture in which BHs correlate differently with different galaxy components. BHs are found in pure-disk galaxies, so classical (elliptical-galaxy-like) bulges are not necessary to grow BHs. But BHs do not correlate with galaxy disks. And any correlations with disk-grown pseudobulges or halo dark matter are so weak as to imply no close coevolution. We suggest that there are four regimes of BH feedback. 1- Local, stochastic feeding of small BHs in mainly bulgeless galaxies involves too little energy to result in coevolution. 2- Global feeding in major, wet galaxy mergers grows giant BHs in short, quasar-like "AGN" events whose feedback does affect galaxies. This makes classical bulges and coreless-rotating ellipticals. 3- At the highest BH masses, maintenance-mode feedback into X-ray gas has the negative effect of helping to keep baryons locked up in hot gas. This happens in giant, core-nonrotating ellipticals. They inherit coevolution magic from smaller progenitors. 4- Independent of any feedback physics, the averaging that results from successive mergers helps to engineer tight BH correlations.

On some interrelations of generalized $q$-entropies and a generalized Fisher information, including a Cramér-Rao inequality

description: In this communication, we describe some interrelations between generalized $q$-entropies and a generalized version of Fisher information. In information theory, the de Bruijn identity links the Fisher information and the derivative of the entropy. We show that this identity can be extended to generalized versions of entropy and Fisher information. More precisely, a generalized Fisher information naturally pops up in the expression of the derivative of the Tsallis entropy. This generalized Fisher information also appears as a special case of a generalized Fisher information for estimation problems. Indeed, we derive here a new Cramér-Rao inequality for the estimation of a parameter, which involves a generalized form of Fisher information. This generalized Fisher information reduces to the standard Fisher information as a particular case. In the case of a translation parameter, the general Cramér-Rao inequality leads to an inequality for distributions which is saturated by generalized $q$-Gaussian distributions. These generalized $q$-Gaussians are important in several areas of physics and mathematics. They are known to maximize the $q$-entropies subject to a moment constraint. The Cramér-Rao inequality shows that the generalized $q$-Gaussians also minimize the generalized Fisher information among distributions with a fixed moment. Similarly, the generalized $q$-Gaussians also minimize the generalized Fisher information among distributions with a given $q$-entropy.

A cluster pair : A3532 and A3530

description: We present a detailed study of a close pair of clusters of galaxies, A3532 and A3530, and their environments. The \textit{Chandra} X-ray image of A3532 reveals presence of substructures on scales of $\sim$20$^{\prime\prime}$ in its core. XMM-Newton maps of the clusters show excess X-ray emission from an overlapping region between them. Spectrally determined projected temperature and entropy maps do not show any signs of cluster scale mergers either in the overlapping region or in any of the clusters. In A3532, however, some signs of the presence of galaxy scale mergers are visible e.g., anisotropic temperature variations in the projected thermodynamic maps, a wide angled tailed (WAT) radio source in the brighter nucleus of its dumbbell Brightest Cluster Galaxy (BCG), and a candidate X-ray cavity coincident with the northwestern extension of the WAT source in the low-frequency radio observations. The northwestern extension in A3532 seems either a part of the WAT or an unrelated diffuse source in A3532 or in the background. There is an indication that the cool core in A3532 has been disrupted by the central AGN activity. A reanalysis of the redshift data reinforces the close proximity of the clusters. The excess emission in the overlapping region appears to be a result of tidal interactions as the two clusters approach each other for the first time. However, we can not rule out the possibility of the excess being due to the chance superposition of their X-ray halos.

description: Interpreting galactic luminosity requires assumptions about the galaxy-wide initial mass function (gwIMF), often assumed invariant in most stellar population synthesis (SPS) models. If stars form in clusters with metallicity- and density-dependent \textit{stellar IMFs}, the integrated galaxy-wide IMF (IGIMF) can be calculated, with its shape depending on the star formation rate (SFR) and metallicity. The shape of the IGIMF thus depends on the star formation rate (SFR) and metallicity. We develop the \texttt{SPS-VarIMF} code which enables us for the first time to compute the spectra, luminosities, and remnant populations of galaxies in the context of the varying gwIMF with time, SFR, and an assumed metallicity. Using the \texttt{SPS-VarIMF} code one can calculate how the interpretation from the integrated galactic light may change if the underlying galaxy-wide IMF is assumed to be environmentally dependent instead of being invariant. In particular, we compare the time evolution of the galaxy color and the stellar mass-to-light ratio in different bands for the IGIMF and invariant canonical gwIMF assuming constant and delayed-$τ$ star formation histories. We show that the underlying gwIMF can be determined by examining the colors and luminosities of late-type galaxies in UV and optical bands. On the other hand, for early-type galaxies, it is difficult to distinguish which gwIMF is valid since adopting the different gwIMFs yields almost identical colors. However, their gwIMF-dependent $M/L$ ratios differ by up to an order of magnitude. Massive present-day elliptical galaxies would have been $10^4$ times as bright as at present when they were forming.
