description: The availability of asteroseismic constraints for a large number of red giants with CoRoT and in the near future with Kepler, paves the way for detailed studies of populations of galactic-disk red giants. We investigate which information on the observed population can be recovered by the distribution of the observed seismic constraints: the frequency of maximum power of solar-like oscillations ($ν_{max}$) and the large frequency separation ($Δν$). We use the distribution of $ν_{max}$ and of $Δν$ observed by CoRoT in nearly 800 red giants in the first long observational run, as a tool to investigate the properties of galactic red-giant stars through the comparison with simulated distributions based on synthetic stellar populations. We can clearly identify the bulk of the red giants observed by CoRoT as red-clump stars, i.e. post-flash core-He-burning stars. The distribution of $ν_{max}$ and of $Δν$ give us access to the distribution of the stellar radius and mass, and thus represent a most promising probe of the age and star formation rate of the disk, and of the mass-loss rate during the red-giant branch. This approach will be of great utility also in the interpretation of forthcoming surveys of variability of red giants with CoRoT and Kepler. In particular, an asteroseismic mass estimate of clump stars in the old-open clusters observed by Kepler, would represent a most valuable observational test of the poorly known mass-loss rate on the giant branch, and of its dependence on metallicity.

description: Der Beitrag stellt die Ergebnisse einer Umfrage zum Einsatz der verschiedenen Personalgruppen in der Sacherschließung an deutschen wissenschaftlichen Bibliotheken vor. Es wurde untersucht, inwieweit mehrere Personalgruppen eingesetzt werden, welche Modelle es für die Aufgabenteilung gibt und wie sich diese bewähren. Von Interesse war dabei insbesondere der Einsatz von Diplom- bzw. Bachelor-Bibliothekarinnen und -Bibliothekaren. Ebenfalls ermittelt wurde die Haltung von Mitarbeiterinnen und Mitarbeitern, die selbst in der Sacherschließung tätig sind, zur Rolle des höheren und des gehobenen Dienstes in der Sacherschließung. The paper presents the results of a survey about the activities of different staff groups in subject cataloguing at academic libraries in Germany. It was examined at how many libraries several staff groups are active in this field, which tasks and responsibilities are assigned to the different groups and how the different models are evaluated. Of special interest were the activities of certified librarians (Diplom or Bachelor) in subject cataloguing. The study also addresses the attitudes of staff members who work in subject cataloguing with regard to the role of academic librarians and certified librarians in subject cataloguing.

Revisiting the "Fundamental Plane" of Black Hole Activity at Extremely Low Luminosities

description: We investigate the origin of the X-ray emission in low-luminosity AGNs (LLAGNs). Yuan & Cui (2005) predicted that the X-ray emission should originate from jets rather than from an advection-dominated accretion flow (ADAF) when the X-ray luminosity $L_{\rm X}$ of the source is below a critical value of $L_{\rm X,crit} \approx 10^{-6}L_{\rm Edd}$. This prediction implies that the X-ray spectrum in such sources should be fitted by jets rather than ADAFs. Furthermore, below $L_{\rm X,crit}$ the correlation between radio ($L_{\rm R}$) and X-ray ($L_{\rm X}$) luminosities and the black hole mass ($M$)--the so-called fundamental plane of black hole activity--should deviate from the general correlation obtained by Merloni, Heinz & Di Matteo (2003) and become steeper. The Merloni et al. correlation is described by ${\rm log}L_{\rm R} =0.6{\rm log}L_{\rm X}+0.78{\rm log}M+7.33$, while the predicted correlation is ${\rm log}L_{\rm R}=1.23{\rm log}L_{\rm X} +0.25{\rm log}M-13.45$. We collect data from the literature to check the validity of these two expectations. We find that among the 16 LLAGNs with good X-ray and radio spectra, 13 are consistent with the Yuan & Cui prediction. For the 22 LLAGNs with $L_{\rm X} < L_{\rm X,crit}$, the fundamental plane correlation is described by ${\rm log}L_{\rm R}=1.22{\rm log}L_{\rm X}+0.23{\rm log}M-12.46 $, also in excellent agreement with the prediction.

description: The binary star delta Sco (HD143275) underwent remarkable brightening in the visible in 2000, and continues to be irregularly variable. The system was observed with the Sydney University Stellar Interferometer (SUSI) in 1999, 2000, 2001, 2006 and 2007. The 1999 observations were consistent with predictions based on the previously published orbital elements. The subsequent observations can only be explained by assuming that an optically bright emission region with an angular size of > 2 +/- 1 mas formed around the primary in 2000. By 2006/2007 the size of this region grew to an estimated > 4 mas. We have determined a consistent set of orbital elements by simultaneously fitting all the published interferometric and spectroscopic data as well as the SUSI data reported here. The resulting elements and the brightness ratio for the system measured prior to the outburst in 2000 have been used to estimate the masses of the components. We find Ma = 15 +/- 7 Msun and Mb = 8.0 +/- 3.6 Msun. The dynamical parallax is estimated to be 7.03 +/- 0.15 mas, which is in good agreement with the revised HIPPARCOS parallax.

description: Zusammenfassung: Bis heute ist nicht bekannt, wie viele Personen 1933 bis 1945 im Bibliothekswesen innerhalb des deutschen Machtbereichs Opfer der NS-Diktatur geworden sind. In zweijährigen Recherchen wurden 250 (vor allem wissenschaftliche) Bibliothekarinnen und Bibliothekare ermittelt, die in Deutschland, in Österreich und in den durch deutsche Truppen besetzten Ländern Opfer dieser Diktatur wurden. 89 von ihnen waren Mitglieder des Vereins Deutscher Bibliothekare (VDB). Dieser zweite Teil der Dokumentation informiert eingangs über 131 Exilaufenthalte von Bibliothekarinnen und Bibliothekaren, die ab 1933 emigrieren mussten. Dann wird an 63 Kolleginnen und Kollegen erinnert, die Widerstand gegen die NS-Diktatur geleistet haben. Abschließend sind 52 Fälle der Deportation in ein Konzentrationslager oder ein Ghetto dokumentiert. Auch Überlebende und Remigranten werden verzeichnet. Zu diesen Themen waren bisher kaum Fakten bekannt. Summary: Up to now it hasn’t been known exactly how many librarians became victims of the Nazi regime between 1933 and 1945 in the area of German control. As a result of a two-year research, 250 (mostly academic) librarians were identified as victims of the regime in Germany, Austria and in the occupied countries. There were 89 members of the Association of German Librarians (VDB) among them. The second part of this documentation starts with 131 exiles of librarians who had to leave their country. It continues with a commemoration of 63 librarians resisting NS-dictatorship in their professional or private lives. The paper closes with a documentation of 52 cases of deportation to a Nazi concentration camp or a ghetto. Surviving persons and remigrants are also listed. Very few facts were known about these topics until today.

description: The paper showcases the effectiveness of SO(2,1) algebraic techniques in stretched Coulomb basis for hydrogenic perturbation theory. The techniques eliminate the need for infinite sums over discrete states and continuum integral contributions required by conventional hydrogenic basis, making calculations more efficient. The paper applies these techniques to the second order Stark effect of the ground state in a relativistic hydrogen atom, adding two simple terms via the SO(2,1) method. The results demonstrate the potential of these techniques to simplify calculations and obtain results more efficiently, suggesting future research can explore their broader applications in hydrogenic perturbation theory.
SDSS J102347.6+003841: A Millisecond Radio Pulsar Binary That Had A Hot Disk During 2000-2001

description: The Sloan Digital Sky Survey (SDSS) source J102347.6+003841 was recently revealed to be a binary 1.69 millisecond radio pulsar with a 4.75 hr orbital period and a ~0.2 M_sun companion. Here we analyze the SDSS spectrum of the source in detail. The spectrum was taken on 2001 February 1, when the source was in a bright state and showed broad, double-peaked hydrogen and helium lines -- dramatically different from the G-type absorption spectrum seen from 2003 onward. The lines are consistent with emission from a disk around the compact primary. We derive properties of the disk by fitting the SDSS continuum with a simple disk model, and find a temperature range of 2000--34000 K from the outer to inner edge of the disk. The disk inner and outer radii were approximately 10^9 and 5.7x10^10 cm, respectively. These results further emphasize the unique feature of the source: it is likely a system at the end of its transition from an X-ray binary to a recycled radio pulsar. The disk mass is estimated to have been ~10^23 g, most of which would have been lost due to pulsar wind ablation (or due to the propeller effect if the disk had extended inside the light cylinder of the pulsar) before the final disk disruption event. The system could undergo repeated episodes of disk formation. Close monitoring of the source is needed to catch the system in its bright state again, so that this unusual example of a pulsar-disk interaction can be studied in much finer detail

description: To develop bona fide atomistic models of nAChRs in their different physiological states, i.e. resting, active and desensitized, the following initial coordinates from cryo-EM were used: nAChR α7:  [PDB:7KOO]: nAChR α7 in the resting state bound to α-bungarotoxin (chains F-J) and calcium ions (residue name CAL) [PDB:7KOQ]: nAChR α7 in the desensitized state bound to epibatidine (residue name EPJ) and calcium ions (residue name CAL) nAChR α4β2:  [PDB:6CNJ]: nAChR α4β2 in the 2α:3β stoichiometry in the desensitized state bound to nicotine (residue name NCT) and in presence of cholesterol (residue name CHL1) in the transmembrane domain nAChR α3β4:  [PDB:6PV8]: nAChR α3β4 in the desensitized state bound to AT-1001 (residue name P1M) and in presence of cholesterol (residue name CHL1) in the transmembrane domain nAChR muscle-type:  [PDB:6UWZ]: nAChR muscle-type in resting state bound to α-bungarotoxin (chains F and G) All protein structures above were embedded in a membrane composed of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) bilayer, put in a solvation box containing water (TIP3P model) and a physiological concentration (0.15 M) of NaCl (residue names Sod and CLA). The molecular systems were relaxed by a hundred nanoseconds of all-atom Molecular Dynamics (MD) at room temperature and 1 bar pressure using the CHARMM36m force field. The most populated cluster was extracted from the MD trajectory and considered as the (statistically) relevant configuration for the physiological state. For each cluster center, we provide Cartesian coordinates of the protein with ligands and the full system including the solvent and the membrane. To ensure the reproducibility of data, PROTOCOL.pdf contains detailed information about the preparation of the models.

description: All existing ``positive'' results on two neutrino double beta decay in different nuclei were analyzed. Using the procedure recommended by the Particle Data Group, weighted average values for half-lives of $^{48}$Ca, $^{76}$Ge, $^{82}$Se, $^{96}$Zr, $^{100}$Mo, $^{100}$Mo - $^{100}$Ru ($0^+_1$), $^{116}$Cd, $^{130}$Te, $^{150}$Nd, $^{150}$Nd - $^{150}$Sm ($0^+_1$) and $^{238}$U were obtained. Existing geochemical data were analyzed and recommended values for half-lives of $^{128}$Te, $^{130}$Te and $^{130}$Ba are proposed. We recommend the use of these results as presently the most precise and reliable values for half-lives.

Nikias : an Athenian general of the fifth century B.C.
Creators: name: Postgate, Marion Myfanwy
Publisher: name: University of British Columbia
Year: 2011

description: My thesis is a biography of Nikias, an Athenian general and politician who lived from c. 470 to 413 B.C. Chapter I gives an account of the sources I have used (chiefly Thucydides' History), and Chapter II information about his family. The remaining chapters are a chronological account of his career: Chapter III dealing with the first portion of the Peloponnesian War known as the Archidamian War (431-421); Chapter IV, the Peace of Nikias (421) and the following uneasy years of truce; and Chapter V, the Sicilian Expedition (415-413), the second portion of the Peloponnesian War, which was not concluded until 404. Parts of the thesis cover material not directly pertaining to Nikias but needed for an understanding of his actions. I have intended as my theme a defence of his career. Most scholars are agreed that Nikias was a respectable man, but decry his abilities as a general and politician. They think of his final disgrace in Sicily and analyse the earlier portions of his career in light of his eventual failure; not considering that Nikias was by then changed into an old and sick man. It is impossible to recreate Nikias as a brilliant politician and strategist; he was not. Nevertheless I hope my account will make readers judge him more fairly than they perhaps have done before.

description: Let $x$ be a complex random variable such that ${\E {x}=0}$, ${\E |x|^2=1}$, ${\E |x|^{4} < \infty}$. Let $x_{ij}$, $i,j \in \{1,2,...\}$ be independet copies of $x$. Let ${\Xb=(N^{-1/2}x_{ij})}$, $1\leq i,j \leq N$ be a random matrix. Writing $\Xb^*$ for the adjoint matrix of $\Xb$, consider the product $\Xb^m{\Xb^*}^m$ with some $m \in \{1,2,...\}$. The matrix $\Xb^m{\Xb^*}^m$ is Hermitian positive semi-definite. Let $λ_1,λ_2,...,λ_N$ be eigenvalues of $\Xb^m{\Xb^*}^m$ (or squared singular values of the matrix $\Xb^m$). In this paper we find the asymptotic distribution function \[ G^{(m)}(x)=\lim_{N\to\infty}\E{F_N^{(m)}(x)} \] of the empirical distribution function \[ {F_N^{(m)}(x)} = N^{-1} \sum_{k=1}^N {\mathbb{I}{\{λ_k \leq x\}}}, \] where $\mathbb{I} \{A\}$ stands for the indicator function of event $A$. The moments of $G^{(m)}$ satisfy \[ M^{(m)}_p=\int_{\mathbb{R}}{x^p dG^{(m)}(x)}=\frac{1}{mp+1}\binom{mp+p}{p}. \] In Free Probability Theory $M^{(m)}_p$ are known as Fuss--Catalan numbers. With $m=1$ our result turns to a well known result of Marchenko--Pastur 1967.

description: We discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia in the light of computations of higher-order QCD corrections both in the Colour-Singlet (CS) and Colour-Octet (CO) channels and the inclusion of the contribution arising from the s-channel cut in the CS channel. We also discuss new observables meant to better discriminate between these different mechanisms.

Theoretical Aspects of Charge Correlations in $θ$-(BEDT-TTF)$_2X$
Creators: name: Kuroki, Kazuhiko
Publisher: name: arXiv
Year: 2009
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: A review is given on the theoretical studies of charge correlations in $θ$-(BEDT-TTF)$_2X$. Various studies show that within a purely electronic model on the $θ$-type lattice with the on-site $U$ and the nearest neighbor $V_p$ and $V_c$ interactions, the diagonal stripe, c-axis three-fold, and the vertical stripe charge correlations are favored in the regime $V_p< V_c$, $V_p\sim V_c$, and $V_p> V_c$, respectively. In the realistic parameter regime of $V_p\sim V_c$, there is a competition between c-axis three fold state and the diagonal stripe state. Since these are different from the experimentally observed a-axis three fold and the horizontal stripe charge correlations, additional effects have to be included in order to understand the experiments. The electron-lattice coupling, which tends to distort the lattice into the $θ_d$-type, is found to favor the horizontal stripe state, suggesting that the occurrence of this stripe ordering in the actual materials may not be of purely electronic origin. On the other hand, distant electron-electron interactions have to be considered in order to understand the a-axis three fold correlation, whose wave vector is close to the nesting vector of the Fermi surface. These studies seem to suggest that the minimal model to understand the charge correlation in $θ$-(BEDT-TTF)$_2X$ may be more complicated than expected. Future problems regarding the competition between different types of charge correlations are discussed.

Extensional Instability in Electro-Osmotic Microflows of Polymer Solutions
Creators: name: Bryce, R. M.
name: Freeman, M. R.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Fluid transport in microfluidic systems typically is laminar due to the low Reynolds number characteristic of the flow. The inclusion of suspended polymers imparts elasticity to fluids, allowing instabilities to be excited when substantial polymer stretching occurs. For high molecular weight polymer chains we find that flow velocities achievable by standard electro-osmotic pumping are sufficient to excite extensional instabilities in dilute polymer solutions. We observe a dependence in measured fluctuations on polymer concentration which plateaus at a threshold corresponding to the onset of significant molecular crowding in macromolecular solutions; plateauing occurs well below the overlap concentration. Our results show that electro-osmotic flows of complex fluids are disturbed from the steady regime, suggesting potential for enhanced mixing and requiring care in modeling the flow of complex liquids such as biopolymer suspensions.

Photospheric Motions and Their Effects on the Corona: a Numerical Approach

Publisher: name: arXiv
Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We perform a number of numerical simulations of the solar corona with the aim to understand how it responds to different conditions in the photosphere. By changing parameters which govern the motion of the plasma at the photosphere we study the behavior of the corona, in particular, the effects on the current density generated. An MHD code is used to run simulations, using a 20x20x20 Mm^3 box with time spans ranging from one hundred to several hundreds of minutes. All the experiments show a fast initial increase of the current density, followed by a stabilization around an asymptotic value which depends on the photospheric conditions. These asymptotic average current densities as well as the turn-over points are discussed.

Naturalness and Testability of TeV Seesaw Mechanisms

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

description: After outlining some popular ways to go beyond the standard model so as to generate non-zero but tiny neutrino masses, I focus on several typical seesaw mechanisms and discuss how to get a balance between their theoretical naturalness and their experimental testability. Besides possible collider signatures at the Large Hadron Collider, new and non-unitary CP-violating effects are also expected to show up in neutrino oscillations for type-I, type-(I+II), type-III and double seesaws at the TeV scale.

Temporary Labour Schemes, the New Avenue of Social Mobility: Case Study Vanuatu
Creators: name: Bailey, Rochelle
name: Wells, Sharon
Publisher: name: Canberra, ACT: State, Society and Governance in Melanesia (SSGM) Program, The Australian National University
Year: 2017

description: Since the establishment of Australia’s Seasonal Worker Programme (SWP) in 2012, the number of workers from Vanuatu has increased significantly from 119 to 1533. It has been established that labour mobility improves livelihoods (Bailey 2014; Bedford 2013; Gibson and McKenzie 2014). This is evident throughout out villages and towns in Vanuatu, and is the reason thousands of ni-Vanuatu apply for the SWP every year. Using evidence-based research of ni-Vanuatu workers in the SWP, this paper argues that this strategic policy of encouraging development for Pacific island nations is effective, and, most significantly, that participating in labour migration provides workers with new avenues of social mobility.

Publisher: name: arXiv

description: Various commercial coated conductors were irradiated with fast neutrons in order to introduce randomly distributed, uncorrelated defects which increase the critical current density, Jc, in a wide temperature and field range. The Jc-anisotropy is significantly reduced and the angular dependence of Jc does not obey the anisotropic scaling approach. These defects enhance the irreversibility line in not fully optimized tapes, but they do not in state-of-the-art conductors. Neutron irradiation provides a clear distinction between the low field region, where Jc is limited by the grain boundaries, and the high field region, where depinning leads to dissipation.
