description: Approximate bound state solutions of the Dirac equation with -deformed Woods-Saxon plus a new generalized ring-shaped potential are obtained for any arbitrary L-state. The energy eigenvalue equation and corresponding two-component wave function are calculated by solving the radial and angular wave equations within a shortcut of the Nikiforov-Uvarov method. The solutions of the radial and polar angular parts of the wave function are expressed in terms of the Jacobi polynomials. A new approximation being expressed in terms of the potential parameters is carried out to deal with the strong singular centrifugal potential term L(L+1)/r^2. Under some limitations, we can obtain solution for the ring-shaped Hulthén potential and the standard usual spherical Woods-Saxon potential (q=1).

description: We present the analysis of the X-ray variability and spectral timing properties of the ultraluminous X-ray source (ULX) NGC 5408 X-1, one of the most variable ULXs known so far. The variability properties are used as a diagnostic of the accretion state of the source and to derive estimates of the black hole (BH) mass. The observed high level of fast X-ray variability (fractional root-mean-square variability - rms - amplitude of $\sim$ 30 percent in the hard energy band), the hardening of the fractional rms spectrum, and the properties of the QPO, all resemble those of a source in a hard-intermediate accretion state. We confirm the previous detection of a soft lag in the X-ray light curves of the source during 2006 and 2008 observations and find that the soft lag is still present in the more recent 2010/2011 observations. Using the entire available XMM-Newton data set (public as of February 2012) we observe that the soft lag (of few seconds amplitude) is detected over a relatively large range of frequencies ($ν\sim 5-90$ mHz), which always includes the QPO frequencies. The soft lag displays energy-dependence, with the (absolute) amplitude increasing as a function of energy separation. We find close analogies with soft lags associated to type-C QPOs in BH binary systems (although an association to other types of QPOs cannot be completely excluded), as well as with reverberation lags observed in AGN. In both cases an intermediate mass BH (IMBH) solution appears the most plausible.

description: The Dirac equation is solved to obtain its approximate bound states for a spin-1/2 particle in the presence of trigonometric Poschl-Teller (tPT) potential including a Coulomb-like tensor interaction with arbitrary spin-orbit quantum number $κ$ using an approximation scheme to substitute the centrifugal terms k(k+1)/r^2. In view of spin and pseudo-spin (p-spin) symmetries, the relativistic energy eigenvalues and the corresponding two-component wave functions of a particle moving in the field of attractive and repulsive tPT potentials are obtained using the asymptotic iteration method (AIM). We present numerical results in the absence and presence of tensor coupling $A$ and for various values of spin and p-spin constants and quantum numbers n and k. The non-relativistic limit is also obtained.

description: To poignantly demonstrate the effect of metaphors on epistemic as well as affective mechanisms of whole groups, I will look at two echo chambers that have formed within the virtual realm, namely ProAna (pro-anorexia) worlds and the Incel (involuntary celibates) community. Echo chambers such as these exert a particularly heightened use of metaphors as well as a very specialized and adapted vocabulary tailored to the respective needs, which makes them a fruitful space to examine the workings of highly expressive metaphors. In this thesis I outline and defend the basis for the claim that metaphors, used in the specific environment of echo chambers, are used as tools which corroborate, maintain, and reinforce the epistemic as well as affective scaffold that is already in place.

description: Leo P is a low-luminosity dwarf galaxy discovered through the blind HI Arecibo Legacy Fast ALFA (ALFALFA) survey. The HI and follow-up optical observations have shown that Leo P is a gas-rich dwarf galaxy with both active star formation and an underlying older population, as well as an extremely low oxygen abundance. Here, we measure the distance to Leo P by applying the tip of the red giant branch (TRGB) distance method to photometry of the resolved stellar population from new Large Binocular Telescope (LBT) V and I band imaging. We measure a distance modulus of 26.19 (+0.17/-0.50) mag corresponding to a distance of 1.72 (+0.14/-0.40) Mpc. Although our photometry reaches 3 magnitudes below the TRGB, the sparseness of the red giant branch (RGB) yields higher uncertainties on the lower limit of the distance. Leo P is outside the Local Group with a distance and velocity consistent with the local Hubble flow. While located in a very low-density environment, Leo P lies within ~0.5 Mpc of a loose association of dwarf galaxies which include NGC 3109, Antlia, Sextans A, and Sextans B, and 1.1 Mpc away from its next nearest neighbor, Leo A. Leo P is one of the lowest metallicity star-forming galaxies known in the nearby universe, comparable in metallicity to I Zw 18 and DDO 68, but with stellar characteristics similar to dwarf spheriodals (dSphs) in the Local Volume such as Carina, Sextans, and Leo II. Given its physical properties and isolation, Leo P may provide an evolutionary link between gas-rich dwarf irregular galaxies and dSphs that have fallen into a Local Group environment and been stripped of their gas.

Failed Supernovae Explain the Compact Remnant Mass Function

description: One explanation for the absence of higher mass red supergiants (16.5 Msun < M < 25Msun) as the progenitors of Type IIP supernovae (SNe) is that they die in failed SNe creating black holes. Simulations show that such failed SNe still eject their hydrogen envelopes in a weak transient, leaving a black hole with the mass of the star's helium core (5-8Msun). Here we show that this naturally explains the typical masses of observed black holes and the gap between neutron star and black hole masses without any fine-tuning of the SN mechanism beyond having it fail in a mass range where many progenitor models have density structures that make the explosions more likely to fail. There is no difficulty including this ~20% population of failed SNe in any accounting of SN types over the progenitor mass function. And, other than patience, there is no observational barrier to either detecting these black hole formation events or limiting their rates to be well below this prediction.

Why the Return Notion Matters
Creators: name: Dorfleitner, Gregor
Publisher: name: Universität Regensburg
Year: 2003
Subjects: subject: 330 Wirtschaft

description: Returns can be defined as log returns or as simple returns. Whereas on a numerical level the difference between these two terms is small as long as the return values are close to zero, there can be non-negligible differences if we look at expected values and (co)variances in a stochastic context. This paper examines the consequences of mixing up the two return terms when variances and convariances are considered. Three applications show that these consequences can be severe in the sense of suboptimal portfolio selection or invalid betas. The paper argues that more awareness of the suited return term is necessary.
On a Possible Size/Color Relationship in the Kuiper Belt

description: Color measurements and albedo distributions introduce non-intuitive observational biases in size-color relationships among Kuiper Belt Objects (KBOs) that cannot be disentangled without a well characterized sample population with systematic photometry. Peixinho et al. report that the form of the KBO color distribution varies with absolute magnitude, H. However, Tegler et al. find that KBO color distributions are a property of object classification. We construct synthetic models of observed KBO colors based on two B-R color distribution scenarios: color distribution dependent on H magnitude (H-Model) and color distribution based on object classification (Class-Model). These synthetic B-R color distributions were modified to account for observational flux biases. We compare our synthetic B-R distributions to the observed 'Hot' and 'Cold' detected objects from the Canada-France Ecliptic Plane Survey and the Meudon Multicolor Survey. For both surveys, the Hot population color distribution rejects the H-Model, but is well described by the Class-Model. The Cold objects reject the H-Model, but the Class-Model (while not statistically rejected) also does not provide a compelling match for data. Although we formally reject models where the structure of the color distribution is a strong function of H magnitude, we also do not find that a simple dependence of color distribution on orbit classification is sufficient to describe the color distribution of classical KBOs.

description: Using methods from random matrix theory researchers have recently calculated the full spectra of random networks with arbitrary degrees and with community structure. Both reveal interesting spectral features, including deviations from the Wigner semicircle distribution and phase transitions in the spectra of community structured networks. In this paper we generalize both calculations, giving a prescription for calculating the spectrum of a network with both community structure and an arbitrary degree distribution. In general the spectrum has two parts, a continuous spectral band, which can depart strongly from the classic semicircle form, and a set of outlying eigenvalues that indicate the presence of communities.

description: We theoretically study the superconducting proximity effect in silicene, which features massive Dirac fermions with a tunable mass (band gap), and compute the conductance across a normal/superconductor (N/S) silicene junction, the non-local conductance of an N/S/N junction, and the supercurrent flowing in an S/N/S junction. It is demonstrated that the transport processes consisting of local and non-local Andreev reflection may be efficiently controlled via an external electric field owing to the buckled structure of silicene. In particular, we demonstrate that it is possible to obtain a fully spin-valley polarized crossed Andreev reflection process without any contamination of elastic cotunneling or local Andreev reflection, in stark contrast to ordinary metals. It is also shown that the supercurrent flowing in the S/N/S junction can be fully spin-valley polarized and that it is controllable by an external electric field.

Flight-associated discharge pattern in a weakly electric fish, Gnathonemus petersii (Mormyridae, Teleostei)
Creators: name: Kramer, Bernd
Publisher: name: Universität Regensburg
Year: 1976
Subjects: subject: 590 Tiere (Zoologie)

description: A Gnathonemus petersii which is put into the tank of a Mortnyrtts rume, or of an electrically silenced G. petersii, displays a discharge rate which is only one fourth (8 Hz) the rate exhibited by an attacking, territory-defending animal. In both instances, the variability of intervals is great. In contrast to the bimodal histogram of an attacking animal, the histogram of an inferior, fleeing fish displays only one mode. This mode is identical to the burst activity-mode of the resting histogram, and different froin the swimming histogram mode. So the histogram displayed by an attacked and persecuted animal is significantly different from the histograms exhibited by i) isolated resting, ii) isolated swimming, and iii) attacking fish. During an attack-elicited escape reaction, G. petersii increases its discharge rate up to 55 Hz in a step-like fashion, while regularising the length of successive intervals ("fleeing signal"). The step-like discharge rate increase is also shown by the receiver of an Approach who does not move. This suggests that the step-like discharge rate increase, associated with the escape reaction, is not an incidental response to changed motor activity. The "fleeing signal" presumably is i) an incidental response to a vegetative reaction, or ii) it may have the significance of a signal communicating a socially relevant message (e.g. threat).
 Der schwachelektrische Fisch Gnathoneqnus petersii sendet in einem fremden Revier mit einer um etwa das Vierfache niedrigeren durchschnittlichen Entladungsrate (ca. 8 Hz) als ein aggressives, revierverteidigendes Tier. Wie bei diesem ist die Variationsbreite der Intervalle groß. Im Unterschied zu dem Histogramm eines angreifenden Tieres, das zwei Modi besitzt, hat das Histogramm eines inferioren, fluchtbereiten Fisches nur einen einzigen Modus. Dieser Modus ist mit dem "Burst-Aktivitäts"-Modus des Ruhehistogramms identisch, nicht jedoch mit dem Modus des Schwimmhistogrammes. Das Histogramm eines Tieres im fremden Revier, in dem es angegriffen und in die Flucht gejagt wird, unterscheidet sich signifikant von den drei bisher bekannten Histogrammtypen, die man bei (I) isolierten ruhenden, (2) isolicrten schwimmenden oder bei (3) einem Partner angreifenden Fischen findet. Während des Angegriffenwerdens und der Fluchtreaktion erhöht G. petersii sprungartig seine Entladungsrate auf bis zu 55 Hz; gleichzeitig wird die Länge aufeinanderfolgender Intervalle "regularisiert". Die sprunghafte Erhöhung der Entladungsrate wird auch dann gezeigt, wenn das Tier auf eine Stoßintention des Revierinhabers hin sich nicht vom Platz rührt. Dies legt die Vermutung nahe, daß die sprunghafte Erhöhung der Entladungsrate während der Fluchtreaktion nicht eine Begleiterscheinung der erhöhten motorischen Aktivität sein kann, sondern entweder a) eine Folgeerscheinung einer vegetativen Reaktion ist oder b) spezifischen Signal-(z.B. Droh-) Charakter hat.

description: This paper investigates empirically smoothing-out ratios and average holding periods of different Eurex futures such as the Euro-Bund, the DAX, the DJ Euro STOXX 50 future and others from 1999 to 2002. A methodology that only needs daily volume and open interest data is presented (including an innovative open interest correction algorithm). It can be shown that average holding periods decrease over time in most of the examined futures. Other interesting results are the June contract phenomenon in the DAX future and a 09/11 effect in several Eurex futures.

description: Detectors planned for use at the Large Hadron Collider will operate in a radiation field produced by beam collisions. To predict the radiation damage to the components of the detectors, prototype devices are irradiated at test beam facilities that reproduce the radiation conditions expected. The profile of the test beam and the fluence applied per unit time must be known. Techniques such as thin metal foil activation and radiographic image analysis have been used to measure these; however, some of these techniques do not operate in real time, have low sensitivity, or have large uncertainties. We have developed a technique to monitor in real time the beam profile and fluence using an array of $p-i-n$ semiconductor diodes whose forward voltage is linear with fluence over the fluence regime relevant to, for example, tracking in the LHC Upgrade era. We have demonstrated this technique in the 800 MeV proton beam at the LANSCE facility of Los Alamos National Laboratory.

We indicate a few benchmark points consistent with different dark matter annihilation processes where third family squarks are lighter than the first two as a requirement to keep the Higgs mass within the limit. We show that bottom rich and leptonic final states have better reach in such parameter space points and is the most likely scenario to discover SUSY at the upcoming run of LHC with center-of-mass energy 14 TeV.

Towards an Hybrid Hodgkin-Huxley Action Potential Generation Model

description: Mathematical models for the generation of the action potential can improve the understanding of physiological mechanisms that are consequence of the electrical activity in neurons. In such models, some equations involving empirically obtained functions of the membrane potential are usually defined. The best known of these models, the Hodgkin-Huxley model, is an example of this paradigm since it defines the conductances of ion channels in terms of the opening and closing rates of each type of gate present in the channels. These functions need to be derived from laboratory measurements that are often very expensive and produce little data because they involve a time-space-independent measurement of the voltage in a single channel of the cell membrane. In this work, we investigate the possibility of finding the Hodgkin-Huxley model's parametric functions using only two simple measurements (the membrane voltage as a function of time and the injected current that triggered that voltage) and applying Deep Learning methods to estimate these functions. This would result in an hybrid model of the action potential generation composed by the original Hodgkin-Huxley equations and an Artificial Neural Network that requires a small set of easy-to-perform measurements to be trained. Experiments were carried out using data generated from the original Hodgkin-Huxley model, and results show that a simple two-layer artificial neural network (ANN) architecture trained on a minimal amount of data can learn to model some of the fundamental proprieties of the action potential generation by estimating the model's rate functions.

description: We consider planar massless scalar waves impinging upon a Kerr black hole, for general angles of incidence. We compute the absorption cross section via the partial wave approach, and present a gallery of results. In the low-frequency regime, we show that the cross section approaches the horizon area; in the high-frequency regime, we show that the cross section approaches the geodesic capture cross section. In the aligned case, we extend the complex angular momentum method to obtain a `sinc' approximation, which relates the regular high-frequency oscillations in the cross section to the properties of the polar null orbit. In the non-aligned case, we show, via a semi-analytic approximation, that the reduction in symmetry generates a richer, less regular absorption cross section. We separate the absorption cross section into corotating and counterrotating contributions, showing that the absorption is larger for counterrotating waves, as expected.

description: Time-dependent CP asymmetry measurements in $D\to h^+h^-$ decays, where $h=π$ or $ρ$ can be used to constrain the angle $β_c$ of the $cu$ unitarity triangle up to theoretical uncertainties. Here we discuss the theoretical uncertainty from penguin contributions that can be mitigated through the use of isospin analyses. We show that uncertainty from penguin pollution on a measurement of $β_c$ (or alternatively the mixing phase) in $D^0\to π^+π^-$ ($ρ^+ρ^-$) decays is $2.7^\circ$ ($4.6^\circ$). We also comment on the applicability of this method to $D^0\toρπ$ decays for which measurements of weak phases with a precision below the one degree level may be possible.

description: A longitudinal social network evolves over time through the creation and/ or deletion of links among a set of actors (e.g. individuals or organizations). Longitudinal social networks are studied by network science and social science researchers to understand networke volution, trend propagation, friendship and belief formation, diffusion of innovation, the spread of deviant behavior and more. In the current literature, there are different approaches and methods (e.g. Sampsons approach and the markov model) to study the dynamics of longitudinal social networks. These approaches and methods have mainly been utilised to explore evolutionary changes of longitudinal social networks from one state to another and to explain the underlying reasons for these changes. However, they cannot quantify the level of dynamicity of the over time network changes and the contribution of individual network members (i.e. actors) to these changes. In this study, we first develop a set of measures to quantify different aspects of the dynamicity of a longitudinal social network. We then apply these measures, in order to conduct empirical investigations, to two different longitudinal social networks. Finally, we discuss the implications of the application of these measures and possible future research directions of this study.

description: The chemical abundances of metal-poor stars provide a great deal of information regarding the individual nucleosynthetic processes that created the observed elements and the overall process of chemical enrichment of the galaxy since the formation of the first stars. Here we review the abundance patterns of the neutron-capture elements (Z > 38) in those metal-poor stars and our current understanding of the conditions and sites of their production at early times. We also review the relative contributions of these different processes to the build-up of these elements within the galaxy over time, and outline outstanding questions and uncertainties that complicate the interpretation of the abundance patterns observed in metal-poor stars. It is anticipated that future observations of large samples of metal-poor stars will help discriminate between different proposed neutron-capture element production sites and better trace the chemical evolution of the galaxy.

The Attack Frequency of Gnathonemus petersii towards Electrically Silent (Denervated) and Intact Conspecifics, and towards Another Mormyrid ( Brienomyrus niger)
Creators: name: Kramer, Bernd
Publisher: name: Universität Regensburg
Year: 1976
Subjects: subject: 590 Tiere (Zoologie)

description: 1. Aggression experiments were performed with Gnathonemus petersii. Three kinds of stimulus fish were used in random order to elicit attacks: (1) intact conspecifics, (2) electrically silent (operated) conspecifics, and (3) the mormyrid Brienomyrus niger. 2. The aggression indices for the two experiments with B. niger and the intact conspecific, i,e. the two electrically active fish, were similar (p > 0.4), whereas the index for the experiment with the silent conspecific was about one half of the two others (p<0.01, Fig. 2). 3. In none of the three experimental conditions can the behavior sequence displayed by G. petersii be described by a random model, i.e. the occurrence of a given act depended on at least the preceding act (p<0.001, Tables 1-3), as in a first-order Markov chain. For every behavior recognized, the distribution of following acts on a given act found in one group of experiments was significantly different from the same distribution found in one of the two other groups of experiments (Table 4). 4. The behavioral sequences, displayed by the experimental subjects, exhibited redundancies which were only slightly different when an intact (35%) or an electrically silent conspecific (33%) were present (Table 5). A considerable difference between both experiments was found on comparing the information T(x; y) which is common to a preceding behavior x and a following behavor y: in the silent conspecific experiment T(x" y) was more than twice the value found in the intact conspecific experiment (0.65 and 0.28 bit, respectively). In the B. niger experiment T(x; y) was found to be low (0.24 bit). In contrast to both conspecific series of experiments, the redundancy value was also low (23%). A high degree of redundancy of the behavioral sequence in spite of a low amount of internal constraint-both considered to be of prime importance in a communication system-were shown by the experimental G. petersii in the presence of intact conspecifics only. 5. There were considerable differences in the electrical discharge activities of B. niger and G. petersii (Figs. 4-6). B. niger did not display a Preferred Latency Response to G. petersii's pulses (Fig. 7). 6. The results show that by conspecific electric signals information is transmitted which significantly influences the behavior of a recipient G. petersii. These signals seem 'to be strictly species-specific.

Environmental Dependence of Star Formation Law in the Disk and Center of IC 342

description: The Kennicutt-Schmidt (K--S) law in IC 342 is examined using the 12CO-to-H2 conversion factor (Xco,v), which depends on the metallicity and CO intensity. Additionally, an optically thin 13CO (1-0) is also independently used to analyze the K--S law. Xco,v is two to three times lower than the Galactic standard Xco in the galactic center and approximately two times higher than Xco at the disk. The surface densities of molecular gas (Sigma_H2) derived from 12CO and 13CO are consistent at the environment in a high-Sigma_H2 region. By comparing the K-S law in the disk and the central regions of IC 342, we found that the power law index of K-S law (N) increases toward the central region. Furthermore, the dependence of N on Sigma_H2 is observed. Specifically, N increases with Sigma_H2. The derived N in this work and previous observations are consistent with the implication that star formation is likely triggered by gravitational instability in the disk (low-Sigma_H2 region) of IC 342 and both gravitational instability and cloud-cloud collisions in the central region (high-Sigma_H2 regime). In addition, the increasing N toward the high-Sigma_H2 domain also matches the theoretical prediction regarding the properties of giant molecular clouds. The results of IC 342 are supported by the same analysis of other nearby galaxies.

description: The secure transfer of information is an important problem in modern telecommunications. Quantum key distribution (QKD) provides a solution to this problem by using individual quantum systems to generate correlated bits between remote parties, that can be used to extract a secret key. QKD with D-dimensional quantum channels provides security advantages that grow with increasing D. However, the vast majority of QKD implementations has been restricted to two dimensions. Here we demonstrate the feasibility of using higher dimensions for real-world quantum cryptography by performing, for the first time, a fully automated QKD session based on the BB84 protocol with 16-dimensional quantum states. Information is encoded in the single-photon transverse momentum and the required states are dynamically generated with programmable spatial light modulators. Our setup paves the way for future developments in the field of experimental high-dimensional QKD.

description: The effects of a four-arm hammer cracker/ beater on the performance of a newly developed palm kernel cracking machine has been investigated. The work evaluated the performance of the machine with the four arm hammer head attached to it under constant load test. The shaft cracking speed was however, varied from 800 -1600 rpm during this period several parameters were measured. The result showed that as the shaft speed was increasing the cracking time of the palm kernel shells was decreasing. The shortest cracking time of 29.20 seconds occurred at a shaft speed of 1600 rpm while processing 3000g of palm kernels. At a shaft speed of 800 rpm the number of whole nuts was 473, this number increased to 529 at 1000 rpm and continued to decrease to 209 at 1600 rpm. At a shaft speed of 800 rpm the number of un-cracked nut was 21 as the speed continue to increase the number of un cracked nut decreased to 11 at 1000 rpm and continue to decrease to 1 at 1600 rpm, which means as the speed increases the number of un-cracked nut decreases. The work also discovered that the highest effective capacity using the four-arm hammer beater was 102.74 and occurred at the shaft speed of 1600 rpm, likewise the highest cracking efficiency of 99.84 occurred at 1600 rpm. The highest performance efficiency of 82.66 however, occurred at the four-arm hammer speed of 1000 rpm, considering other measured parameters like, number of whole nuts, number of broken nuts, performance efficiency, split nut loss, and overall efficiency the work concluded that the best operating speed for the newly developed palm cracker machine using the four-arm hammer beater is 1000 rpm.

description: While inflation has been an extremely successful cosmological paradigm, almost certainly something have had to have happened before it began. Can the pre-inflationary phase be of any theoretical or phenomenological significance? Could Quantum Gravity have played any interesting role in this story? These are some of the questions we want to explore in this essay written for the Gravity Research Foundation 2013 "Awards for Essays on Gravitation" competition.
