description: The long-term optical and near infrared monitoring observations for a type 1 act ive galactic nucleus NGC 4151 were carried out for six years from 2001 to 2006 b y using the MAGNUM telescope, and delayed response of flux variations in the $K(2.2μm)$ band to those in the $V(0.55μm)$ band was clearly detected. Based on cross correlation analysis, we precisely measured a lag time $Δt$ for eight separate periods, and we found that $Δt$ is not constant changing be tween 30 and 70 days during the monitoring period. Since $Δt$ is the ligh t travel time from the central energy source out to the surrounding dust torus, this is the first convincing evidence that the inner radius of dust torus did ch ange in an individual AGN. In order to relate such a change of $Δt$ with a change of AGN luminosity $L$, we presented a method of taking an average of th e observed $V$-band fluxes that corresponds to the measured value of $Δt$, and we found that the time-changing track of NGC 4151 in the $Δt$ versus $L$ diagram during the monitoring period deviates from the relation of $Δt \propto L^{0.5}$ expected from dust reverberation. This result, combined with t he elapsed time from period to period for which $Δt$ was measured, indicat es that the timescale of dust formation is about one year, which should be taken into account as a new constraint in future studies of dust evolution in AGNs.

description: BBMRI-ERIC established itself in years as one of the key global players in the field of biobanking. While the main focus of BBMRI remains Europe, the organisation understands the need to expand its outreach outside the EU, and to set up a coherent global strategy to develop the field of biobanking globally, and to increase BBMRI’s outreach.
 The ADOPT BBMRI-ERIC project allowed to expand BBMRI’s supporting biobanking activities in different regions in the world, and to develop a multi-year strategy that represents the backbone of future BBMRI global actions.
 Within the project, BBMRI identified four key regions of primary interest: China, Africa, Middle East and the Americas (USA, Latin America). The implementation of the strategy in the regions was paired with existing BBMRI National Nodes activities and connections, therefore maximising the impact of the ADOPT-BBMRI funding. In particular, several of the workshops organised within the project were co-funded by activities of National Nodes within such regions.
 ADOPT BBMRI-ERIC helped to bring the global biobanking community together, and highlighted the need for more international cooperation, based on the centres of excellence and networks identified by BBMRI.

Superstring field theory in the democratic picture

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present a new open superstring field theory, whose string fields carry an arbitrary picture number and reside in the large Hilbert space. The redundancy related to picture number is resolved by treating picture changing as a gauge transformation. A mid-point insertion is imperative for this formalism. We find that this mid-point insertion must include all multi-picture changing operators. It is also proven that this insertion as well as all the multi-picture changing operators are zero weight conformal primaries. This new theory solves the problems with the Ramond sector shared by other RNS string field theories, while naturally unifying the NS and Ramond string fields. When partially gauge fixed, it reduces in the NS sector to the modified cubic superstring field theory. Hence, it shares all the good properties of this theory, e.g., it has analytical vacuum and marginal deformation solutions. Treating the redundant gauge symmetry using the BV formalism is straightforward and results in a cubic action with a single string field, whose quantum numbers are unconstrained. The generalization to an arbitrary brane system is simple and includes the standard Chan-Paton factors and the most general string field consistent with the brane system.

description: Polarized Raman scattering has been performed on CaC6 superconductor. We identify two of the three Raman active Eg phonon modes at 440 and 1508 cm-1 expected for the R-3m space group of CaC6. These first order scattering modes appear along with the D and G bands around 1300 cm-1 and 1600 cm-1 that are similar in origin to the corresponding bands in plain graphite. The intensities of the D and G bands in CaC6 correlate with degree of disorder. The D band arises from the double resonant Raman scattering process; its frequency shifts as a function of excitation energy with approximately 35 cm-1/eV. The double resonant Raman scattering probes phonon excitations with finite wave vector q. We estimate the characteristic spacing of structural defects to be on the scale of about 100 Angstrom by comparing the intensity of the D band and the 1508 cm-1 Eg mode in CaC6 to calibrated intensity ratio of analogous bands in disordered graphites. A sharp superconducting coherence peak at 24 cm-1 is observed below Tc.

Interaction Rules and their Role in Collaboration Software

Publisher: name: University Of Tasmania
Year: 2023
Subjects: Knowledge representation and reasoning

description: The need for on-line teamwork has increased - particularly in transnational collaborations and in regional and rural areas, where distance and time prohibit easy face-to-face communication. On-line collaboration, however, exacerbates the forces that cause difficulties in face-to-face teams. This research identified a facility for creating and monitoring rules of interaction as a useful component for supporting virtual collaboration. Investigations in the disciplines of team psychology, sociology, education, computer supported collaborative work and computer supported collaborative learning, contributed to the design of the facility. Its value was examined in real-life venues and by teamwork experts. Communities build structures devoted to norms of interaction, making these norms overt and regulating interaction. The creation of this social capital is deeply linked to notions of trust, which has been identified as a major contributor to successful virtual teams. There has been little attention paid to providing software support for the sociological aspects of collaboration. Because (virtual) teams are complex, the patterns of interaction that suit a particular team may or may not be predictable, making the creation of software difficult. The sociology underlying community development and the social psychology of team interaction suggest the need for an interaction rule facility and the principles upon which the design should be based. Interaction rule software would further optimise the performance of virtual teams by nurturing trust and may be of assistance in training potential virtual team members in the behavioural issues of on-line collaboration. Can we design software to further develop levels of trust in on-line teams by emulating societal structures of behaviour regulation? A prototype was developed and deployed in educational scenarios to explore this question. The implementation of Phreda, an editable interaction rule facility, addressed a major difficulty in current research ; the inability to determine which team member behaviours are important and what they signify. The rule module positively influenced behaviour. Although team members could construct and manipulate rules, they did not do so voluntarily. Indications were that the participating teams were not sufficiently remote, independent and virtual to make full use of the module. Experts concluded that being involved in Phreda processes would increase member commitment and hence trust. Its effective use should be early in a team’s life for team-critical behaviours and involve all members. Recommended rules can be helpful. Team knowledge gained during the process of rule construction, was seen to be more important than the corresponding artefacts. By using the rule module, members would learn what was behaviour was important, (and hence the meanings of the rule artefacts) and gain skills in the process of establishing team norms.

The focus of our study is the spatially varying polarization state of the resulting field, also known as a polarization grating, generated by this setup. Our proposal combines a theoretical description of the resulting field in terms of its Stokes parameters with an experimental demonstration of the existence of such a polarization grating due to the effects of polarization on beam interference experiments.

description: Tool use has not yet been confirmed in horses, mules or donkeys. As this subject is difficult to research with conventional methods, we used a crowdsourcing approach to gather data. We contacted equid owners and carers and asked them to report and video examples of “unusual” behaviour via a dedicated website. We also searched YouTube and Facebook for videos of equids showing tool use. From 635 reports, including 1014 behaviours, we found 20 cases of tool use, 13 of which were unambiguous in that it was clear that the behaviour was not trained, caused by reduced welfare, incidental or accidental. We then assessed (a) the effect of management conditions on tool use and (b) whether the animals used tools alone, or socially, involving other equids or humans. We found that management restrictions were associated with corresponding tool use in 12 of the 13 cases (p = 0.01), e.g., equids using sticks to scrape hay within reach when feed was restricted. Furthermore, 8 of the 13 cases involved other equids or humans, such as horses using brushes to groom others. The most frequent tool use was for foraging, with seven examples, tool use for social purposes was seen in four cases, and there was just one case of tool use for escape. There was just one case of tool use for comfort, and in this instance, there were no management restrictions. Equids therefore can develop tool use, especially when management conditions are restricted, but it is a rare occurrence.

description: Based on the Sloan Digital Sky Survey Data Release 5 Galaxy Sample, we explore photometric morphology classification and redshift estimation of galaxies using photometric data and known spectroscopic redshifts. An unsupervised method, k-means algorithm, is used to separate the whole galaxy sample into early- and late-type galaxies. Then we investigate the photometric redshift measurement with different input patterns by means of artificial neural networks (ANNs) for the total sample and the two subsamples. The experimental result indicates that ANNs show better performance when the more parameters are applied in the training set, and the mixed accuracy $σ_{mix}=\sqrt{σ_{early}^2+{σ_{late}}^2}$ of photometric redshift estimation for the two subsets is superior to $σ_{z}$ for the overall sample alone. For the optimal result, the rms deviation of photometric redshifts for the mixed sample amounts to 0.0192, that for the overall sample is 0.0196, meanwhile, that for early- and late-type galaxies adds up to 0.0164 and 0.0217, respectively.

description: Fluctuations are important near phase transitions, where they can be difficult to describe quantitatively. Superconductivity in mesoscopic rings is particularly intriguing because the critical temperature is an oscillatory function of magnetic field. There is an exact theory for thermal fluctuations in one-dimensional superconducting rings, which are therefore expected to be an excellent model system. We measure the susceptibility of many rings, one ring at a time, using a scanning SQUID that can isolate magnetic signals from seven orders of magnitude larger background applied flux. We find that the fluctuation theory describes the results and that a single parameter characterizes the ways in which the fluctuations are especially important at magnetic fields where the critical temperature is suppressed.

description: In a recent article, Alli and Sewell formulated a new version of the Dicke-Hepp-Lieb laser model in terms of quantum dynamical semigroups, and thereby extended the macroscopic picture of the model. In the present article, we complement that picture with a corresponding microscopic one, which carries the following new results. (a) The local microscopic dynamics of the model is piloted by the classical, macroscopic field, generated by the collective action of its components; (b) the global state of the system carries no correlations between its constituent atoms after transient effects have died out; and (c) in the latter situation, the state of the system at any time $t$ maximises its entropy density, subject to the constraints imposed by the instantaneous values of its macroscopic variables.

description: We show that a pair of quantized cavity modes interacting with a spectrally broadened ensemble of Lambda-type atoms is analogous to an ensemble of two level systems coupled to a bosonic reservoir. This provides the possibility for an irreversible photon transfer between photon modes. The density of states as well as the quantum state of the reservoir can be engineered allowing the observation of effects such as the quantum Zeno- and anti-Zeno effect, the destructive interference of decay channels and the decay in a squeezed vacuum. As a particular application we discuss a photon diode, i.e. a device which directs a single photon from anyone of two input ports to a common output port.

Shear viscosity of the Quark-Gluon Plasma from a virial expansion

description: We calculate the shear viscosity $η$ in the quark-gluon plasma (QGP) phase within a virial expansion approach with particular interest in the ratio of $η$ to the entropy density $s$, i.e. $η/s$. The virial expansion approach allows us to include the interactions between the partons in the deconfined phase and to evaluate the corrections to a single-particle partition function. In the latter approach we start with an effective interaction with parameters fixed to reproduce thermodynamical quantities of QCD such as energy and/or entropy density. We also directly extract the effective coupling $\ga_{\rm V}$ for the determination of $η$. Our numerical results give a ratio $η/s\approx 0.097$ at the critical temperature $T_{\rm c}$, which is very close to the theoretical bound of $1/(4π)$. Furthermore, for temperatures $T\leq 1.8 T_{\rm c}$ the ratio $η/s$ is in the range of the present experimental estimates $0.1-0.3$ at RHIC. When combining our results for $η/s$ in the deconfined phase with those from chiral perturbation theory or the resonance gas model in the confined phase we observe a pronounced minimum of $η/s$ close to the critical temperature $T_{\rm c}$.

Rational design of metal-mediated DNA G-quadruplexes as DNAzymes

description: Apart from the widely known duplex structure DNA can fold into various secondary structures such as hairpin loops, triplexes and G-quadruplexes. The latter self-assemble from guanine rich strands by Hoogsteen base pairing to form stacked guanine tetrads. Since their discovery, G-quadruplexes became increasingly interesting in the field of chemical biology due to their property to control the elongation of telomeres and the expression of oncogenes. Furthermore, first examples of a DNAzyme activity in G quadruplexes were shown. Drawback of those systems was that the exact position and coordination environment of the catalytic active transition metal ion was largely unknown. In this context, the incorporation of covalently bound ligands into the backbone of G-quadruplex structures would be a next step in the development of DNAzymes. Recently, our group reported a first example of this strategy by incorporation of pyridine ligands, allowing the Cu(II) and Ni(II) mediated folding of G-quadruplex structures. This was then exploited to trigger the folding of a thrombin inhibiting aptamer upon Cu(II) addition. Now, we incorporated – inspired by the natural amino acid histidine – an imidazole-based ligand into G-quadruplex structures. We were able to show a tremendous acceleration of G-quadruplex formation as well as a stabilization by addition of different transition metals such as Cu(II), Ni(II) and Zn(II). By varying the number of incorporated imidazole units, we were able to finetune metal affinities in accordance with their preferred coordination number. The concept of metal mediated GQs was then expanded to design an active peroxidase with the cofactor Hemin which is activated by Cu(II) addition. Further the concept could be exploited for the design of sequences, that offer unsaturated coordination environments for Cu(II). These sequences could then be used for the enantioselective catalysis of Michael-Additions.

In the present paper we extend these results to $g_R$. This also gives a description of the parabolic subgroups of $G_R$. Furthermore, we give a geometric criterion for a parabolic subgroup $P_C$ of $G_C$ to intersect $G_R$ in a parabolic subgroup. This criterion involves the $G_R$-orbit structure of the flag ind-manifold $G_C/P_C$.

Critical scaling and aging in cooling systems near the jamming transition
Creators: name: Head, D. A.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We conduct athermal simulations of freely-cooling, viscous soft spheres around the jamming transition density ϕ_{J}, and find evidence for a growing length ξ(t) that governs relaxation to mechanical equilibrium. ξ(t) is manifest in both the velocity correlation function, and the spatial correlations in a scalar measure of local force balance which we define. Data for different densities ϕcan be collapsed onto two master curves by scaling ξ(t) and t by powers of |ϕ-ϕ_{J}|, indicative of critical scaling. Furthermore, particle transport for ϕ>ϕ_{J} exhibits aging and superdiffusion similar to a range of soft matter experiments, suggesting a common origin. Finally, we explain how ξ(t) at late times maps onto known behavior away from ϕ_{J}.

Staggered chiral perturbation theory in the two-flavor case
Creators: name: Du, Xining
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: I study two-flavor staggered chiral perturbation theory in the light pseudoscalar sector. The pion mass and decay constant are calculated through NLO in the partially-quenched case. In the limit where the strange quark mass is large compared to the light quark masses and the taste splittings, I show that the SU(2) staggered chiral theory emerges from the SU(3) staggered chiral theory, as expected. Explicit relations between SU(2) and SU(3) low energy constants and taste-violating parameters are given. The results are useful for SU(2) chiral fits to asqtad data and allow one to incorporate effects from varying strange quark masses.

Experience versus Talent Shapes the Structure of the Web

description: We use sequential large-scale crawl data to empirically investigate and validate the dynamics that underlie the evolution of the structure of the web. We find that the overall structure of the web is defined by an intricate interplay between experience or entitlement of the pages (as measured by the number of inbound hyperlinks a page already has), inherent talent or fitness of the pages (as measured by the likelihood that someone visiting the page would give a hyperlink to it), and the continual high rates of birth and death of pages on the web. We find that the web is conservative in judging talent and the overall fitness distribution is exponential, showing low variability. The small variance in talent, however, is enough to lead to experience distributions with high variance: The preferential attachment mechanism amplifies these small biases and leads to heavy-tailed power-law (PL) inbound degree distributions over all pages, as well as over pages that are of the same age. The balancing act between experience and talent on the web allows newly introduced pages with novel and interesting content to grow quickly and surpass older pages. In this regard, it is much like what we observe in high-mobility and meritocratic societies: People with entitlement continue to have access to the best resources, but there is just enough screening for fitness that allows for talented winners to emerge and join the ranks of the leaders. Finally, we show that the fitness estimates have potential practical applications in ranking query results.
Relations between multi-resolution analysis and quantum mechanics

Subjects: subject: Mathematical Physics (math-ph)

description: We discuss a procedure to construct multi-resolution analyses (MRA) of $\Lc^2(\R)$ starting from a given {\em seed} function $h(s)$ which should satisfy some conditions. Our method, originally related to the quantum mechanical hamiltonian of the fractional quantum Hall effect (FQHE), is shown to be model independent. The role of a canonical map between certain canonically conjugate operators is discussed. This clarifies our previous procedure and makes much easier most of the original formulas, producing a convenient framework to produce examples of MRA.
Cognitive Radio with Partial Channel State Information at the Transmitter

description: In this paper, we present the cognitive radio system design with partial channel state information known at the transmitter (CSIT).We replace the dirty paper coding (DPC) used in the cognitive radio with full CSIT by the linear assignment Gel'fand-Pinsker coding (LA-GPC), which can utilize the limited knowledge of the channel more efficiently. Based on the achievable rate derived from the LA-GPC, two optimization problems under the fast and slow fading channels are formulated. We derive semianalytical solutions to find the relaying ratios and precoding coefficients. The critical observation is that the complex rate functions in these problems are closely related to ratios of quadratic form. Simulation results show that the proposed semi-analytical solutions perform close to the optimal solutions found by brute-force search, and outperform the systems based on naive DPC. Asymptotic analysis also shows that these solutions converge to the optimal ones solved with full CSIT when the K-factor of Rician channel approaches infinity. Moreover, a new coding scheme is proposed to implement the LA-GPC in practice. Simulation results show that the proposed practical coding scheme can efficiently reach the theoretical rate performance.
