description: Molecular dynamics simulations are performed to investigate the water permeation across the single-walled carbon nanotube (SWCNT) with the radial breathing mode (RBM) vibration. It is found that the RBM can play a significant role in breaking hydrogen bonds of the water chain, accordingly increasing the net flux dramatically, and reducing drastically the average number of water molecules inside the tube with the frequency ranging from 5000 to 11000 GHz, while far away from this frequency region the transport properties of water molecules are almost unaffected by the RBM. This phenomenon can be understood as the resonant response of the water molecule chain to the RBM. Our findings are expected to be helpful for the design of high-flux nanochannels and the understanding of biological activities especially the water channelling.
title: Zarathustra im Awesta und bei Nietzsche eine vergleichende Gegenüberstellung

description: Nietzsche konnte über den historischen Zarathustra (HZ) konkrete Kenntnisse haben, da zu dieser Zeit (bzw. im 18. und 19. Jahrhundert) unter den Gebildeten Europas ein sog. " Orient-Fieber" herrschte, also ein großes Orient-Interesse. Der entscheidende Unterschied zwischen historischem Zarathustra (HZ) und Nietzsches Zarathustra (NZ) scheint darin zu bestehen, dass das Wesen der dualistischen historischen Zarathustra-Religion in der Entscheidungsfreiheit des Menschen zwischen Gut und Böse besteht, während Nietzsches Zarathustra (NZ) zum "amor fati", zum "heiligen Ja-Sagen" erzieht. Dieser Unterschied verringert sich jedoch erheblich, wenn man die Lehre von Nietzsches Zarathustra genauer betrachtet. Bei NZ zeigen sich nämlich immer wieder versteckte Hinweise auf eine Freiheit des Willens, die der Lehre des HZ ähnlich ist.

description: In this paper, we evaluate the suitability of the vehicular devices for supporting data storage and distribution applications. Vehicular storage systems have recently emerged as means for making the information related to the vehicular environment available to vehicular users. Information could either be collected by sensors mounted onboard vehicles or coming from the surrounding environment. Modeling a vehicular data storage and distribution system requires the introduction of a number of parameters, such as the vehicle concentration and transmission range, the value of which may determine the suitability or unsuitability of the vehicular environment for establishing a communication infrastructure with the desired quality. In this paper we show how to solve this problem by resorting to a Markovian model and some results achieved through its application.

Noneuclidean Tessellations and their relation to Reggie Trajectories

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The coefficients in the confluent hypergeometric equation specify the Regge trajectories and the degeneracy of the angular momentum states. Bound states are associated with real angular momenta while resonances are characterized by complex angular momenta. With a centrifugal potential, the half-plane is tessellated by crescents. The addition of an electrostatic potential converts it into a hydrogen atom, and the crescents into triangles which may have complex conjugate angles; the angle through which a rotation takes place is accompanied by a stretching. Rather than studying the properties of the wave functions themselves, we study their symmetry groups. A complex angle indicates that the group contains loxodromic elements. Since the domain of such groups is not the disc, hyperbolic plane geometry cannot be used. Rather, the theory of the isometric circle is adapted since it treats all groups symmetrically. The pairing of circles and their inverses is likened to pairing particles with their antiparticles which then go one to produce nested circles, or a proliferation of particles. A corollary to Laguerre's theorem, which states that the euclidean angle is represented by a pure imaginary projective invariant, represents the imaginary angle in the form of a real projective invariant.

description: We present neutron scattering measurements on single crystals of lightly doped $La_{2-x}Ba_{x}CuO_{4}$, with $0 \leq x \leq? 0.035$. These reveal the evolution of the magnetism in this prototypical doped Mott insulator from a three dimensional (3D) commensurate (C) antiferromagnetic ground state, which orders at a relatively high TN, to a two dimensional (2D) incommensurate (IC) ground state with finite ranged static correlations, which appear below a relatively low effective TN. At low temperatures, the 2D IC magnetism co-exists with the 3D C magnetism for doping concentrations as low as ? 0.0125. We find no signal of a 3D C magnetic ground state by x $\sim$? 0.025, consistent with the upper limit of x $\sim$? 0.02 observed in the sister family of doped Mott insulators, $La_{2-x}Sr_{x}CuO_{4}$. The 2D IC ground states observed for $0.0125 \leq x \leq 0.035$ are diagonal, and are rotated by 45 degrees within the orthorhombic basal plane compared with those previously reported for samples with superconducting ground states: $La_{2-x}Ba_{x}CuO_{4}$, with $0.05 \leq? x \leq? 0.095. We construct a phase diagram based solely on magnetic order parameter measurements, which displays much of the complexity of standard high temperature superconductivity phase diagrams discussed in the literature. Analysis of high energy-resolution inelastic neutron scattering at moderately low temperatures shows a progressive depletion of the very low energy dynamic magnetic susceptibility as x increases from 0.0125 to 0.035. This low energy, dynamic susceptibility falls off? with increasing temperature on a scale much higher than the effective 2D IC TN appropriate to these materials. Appreciable dynamic 2D IC magnetic fluctuations inhabit much of the "pseudogap" regime of the phase diagram.

description: We revisit generalized entropic formulations of the uncertainty principle for an arbitrary pair of quantum observables in two-dimensional Hilbert space. Rényi entropy is used as uncertainty measure associated with the distribution probabilities corresponding to the outcomes of the observables. We derive a general expression for the tight lower bound of the sum of Rényi entropies for any couple of (positive) entropic indices (α,β). Thus, we have overcome the Hölder conjugacy constraint imposed on the entropic indices by Riesz-Thorin theorem. In addition, we present an analytical expression for the tight bound inside the square [0 , 1/2] x [0 , 1/2] in the α-βplane, and a semi-analytical expression on the line β= α. It is seen that previous results are included as particular cases. Moreover, we present an analytical but suboptimal bound for any couple of indices. In all cases, we provide the minimizing states.

description: The resonant state expansion (RSE), a rigorous perturbative method in electrodynamics, is applied to two-dimensional open optical systems. The analytically solvable homogeneous dielectric cylinder is used as unperturbed system, and its Green's function is shown to contain a cut in the complex frequency plane, which is included in the RSE basis. The complex eigenfrequencies of modes are calculated using the RSE for a selection of perturbations which mix unperturbed modes of different orbital momentum, such as half-cylinder, thin-film and thin-wire perturbation, demonstrating the accuracy and convergency of the method. The resonant states for the thin-wire perturbation are shown to reproduce an approximative analytical solution.

Studying bulk water, the water-silica interface, and proton transport with classical molecular dynamics
Creators: name: Lentz, Jesse Michael
Publisher: name: No Publisher Supplied
Year: 2022

description: Classical, atomistic molecular dynamics simulations were conducted to study the structure, dynamics, and proton transport characteristics of bulk water, the water/amorphous silica interface, the water/vapor interface, and nanoconfined water in amorphous silica pores. The bulk water dynamics predicted by the model were compared to the results of ultra-fast IR experiments and to other commonly used classical water models by calculating frequency-frequency correlation functions (FFCFs) of OD stretch vibrations for dilute HDO in H₂O. The effects of static electric fields at various orientations were studied in a 2 nm water film over a silica slab, in a filled 3 nm pore, and in a partially filled 5 nm pore. The dynamics of the water, and the mobility of H₃O⁺ and OH⁻ ions, were found to be significantly slower within 5 Å of the glass surface relative to bulk water and to the water/vapor interface. Particularly rapid H₃O⁺ and OH⁻ diffusion was observed at the water/vapor interface of the planar 2 nm water film under the influence of oblique electric fields. However, in a 5 nm pore containing an 8 Å water film, the water/vapor interface had significantly slower dynamics and slower OH⁻ transport relative to the planar 2 nm system. A filled 3 nm pore containing a smaller volume of water was found to have faster water dynamics and greater OH⁻ mobility than the partially filled 5 nm pore. These results indicate that a water/vapor interface enhances ionic mobility when the water layer is sufficiently thick for a bulk-like region to exist between the water/glass and water/vapor interfaces, but when the water layer is insufficiently thick to produce an intermediate bulk-like region, the vapor interface's dynamics and charge mobility become slower than bulk water. The key result from this work is that while glass surfaces provide an abundant reservoir of ions, the interface significantly slows down the dynamics of the adjacent water, and due to the long residence time of adsorbed ions, surface-bound ions are effectively immobile relative to ions in the water. A greater volume of water in a pore enables ions to travel at a farther distance from the glass surface, which increases their effective mobility by minimizing their probability of approaching and becoming immobilized by the surface.

description: Different computational techniques in combination with molecular dynamics computer simulation are used to to determine the wall-liquid and the wall-crystal interfacial free energies of a modified Lennard-Jones (LJ) system in contact with a solid wall. Two different kinds of solid walls are considered: a flat structureless wall and a structured wall consisting of an ideal crystal with the particles rigidly attached to fcc lattice sites. Interfacial free energies are determined by a thermodynamic integration scheme, the anisotropy of the pressure tensor, the non-equilibrium work method based on Bennett acceptance criteria, and a method using Cahn's adsorption equations based on the interfacial thermodynamics of Gibbs. For the flat wall, interfacial free energies as a function of different densities of the LJ liquid and as a function of temperature along the coexistence curve are calculated. In case of a structured wall, the interaction strength between the wall and the LJ system and the lattice constant of the structured wall are varied. Using the values of the wall-liquid and wall-crystal interfacial energies along with the value for the crystal-liquid interfacial free energy determined previously for the same system by the "cleaving potential method", we obtain the contact angle as a function of various parameters; in particular the conditions are found under which partial wetting occurs.

description: Recently, Energy Management Systems (EMS) have become more integrated and created higher demand of big data processing, thus challenging the real time analysis based on big data technologies. Marz’s Lambda architecture is used for solving problems with querying high amounts of petabyte data. In relation to this, this article presents the Lambda architecture of a particular EMS. The quick and inaccurate results received from the speed layer are replaced by the more precise results of the batch layer. With reference to this, the author proposes a realization of the batch layer based on Hadoop MapReduce technology.
Cypin inhibition as an approach to treat spinal cord injury-induced neuropathic pain
Creators: name: Singh, Nisha K.
Publisher: name: No Publisher Supplied
Year: 2022

description: Spinal cord injury (SCI) involves a primary mechanical phase of injury that results in physical damage to spinal cord tissue and a secondary phase characterized by alterations in molecular signaling that exacerbate the effects of tissue damage. Dysregulation of these cellular processes during the secondary phase of SCI contributes to a host of pathologies including neuroinflammation, loss of motor and autonomic function, and neuropathic pain. Better characterization of the mechanisms underlying secondary injury is crucial for the development of novel targeted therapeutics. Glutamate-induced excitotoxicity is a key contributor to secondary injury, but the signaling pathways that are activated downstream are not completely understood. Modulation of purine metabolism represents a promising approach to mitigating some of the harmful effects of GIE. Guanine-based purines (GBPs), such as guanosine, have been shown to confer neuroprotection and reduce neuropathic pain after SCI, although the mechanisms of action remain largely unknown. In this project, we investigate the potential role of guanine metabolism in recovery after SCI. The guanine deaminase (GDA) enzyme, cypin, catalyzes metabolism of guanine to xanthine and regulates dendrite morphology. We utilize an in vitro model of glutamate-induced excitotoxicity (GIE) in primary spinal cord cultures and an in vivo model of contusion SCI in mice to evaluate the effects of cypin modulation on recovery from SCI. We implemented a combination of immunohistochemical, Western blot, and behavioral analyses for these assessments. Our data suggest that inhibition of cypin GDA activity has both neuroprotective and pain-alleviating effects. We demonstrate that cypin inhibitors preserve neuronal viability after GIE, alleviate mechanical pain sensitivity in injured mice, and lead to an upregulation of A2A adenosine receptors (A2AARs) in the lumbar dorsal horn (LDH) of the spinal cord after SCI. This research examines the pain-attenuating effects of cypin inhibition after SCI and explores modulation of purinergic signaling as a possible mechanism by which these effects are exerted.

description: Many biological fluids have polymeric microstructures and display non-Newtonian rheology. We take advantage of such nonlinear fluid behavior and combine it with geometrical symmetry-breaking to design a novel small-scale propeller able to move only in complex fluids. Its propulsion characteristics are explored numerically in an Oldroyd-B fluid for finite Deborah numbers while the small Deborah number limit is investigated analytically using a second-order fluid model. We then derive expressions relating the propulsion speed to the rheological properties of the complex fluid, allowing thus to infer the normal stress coefficients in the fluid from the locomotion of the propeller. Our simple mechanism can therefore be used either as a non-Newtonian micro-propeller or as a micro-rheometer.

description: Efforts to achieve efficient injection of spin-polarized electrons into a semiconductor, a key prerequisite for developing electronics that exploit the electron's spin degree of freedom, have so far met with limited success. Here we report experimental studies of lateral spin injection and detection through electrodeposited Fe/GaAs tunnel contacts. We demonstrate spin injection efficiencies two orders of magnitude higher than for state-of-the-art contacts fabricated via ultra-high-vacuum methods, including those with MgO or Al2O3 tunnel barriers. To account for this enhancement, we propose that an iron oxide layer that forms at the Fe/GaAs interface during electrodeposition, being magnetic, acts as a tunnel barrier with a spin-dependent height, presenting quantum spin transport calculations for such systems. This serendipitous discovery of greatly enhanced efficiency of spin injection into GaAs via electrodeposited contacts introduces a promising new direction for the development of practical semiconductor spintronic devices.

description: Dass der Antisemitismus in Deutschland nach der Machtübertragung an die Nationalsozialisten innerhalb kürzester Zeit durchsetzungsfähig wurde, war nicht allein Folge der brutalen Zerschlagung der politischen Opposition, der massiven Repression solidarischer Verhaltensweisen und der erfolgreichen ideologischen Durchdringung der deutschen Bevölkerung. Das Tempo, mit dem die Segregation der deutschen Bevölkerung vorangetrieben werden konnte, hing auch mit dem Zerfall institutioneller Organisationen und Strukturen zur Abwehr des Antisemitismus in der Spätphase der Weimarer Republik zusammen. Die Geschichte dieses Scheiterns nachzuzeichnen und die ergriffenen wie ausgeschlagenen Handlungsmöglichkeiten kenntlich zu machen, ist das Anliegen des folgenden Beitrags.
description: Since the granting of equal legal rights to the Jews in 1871, Germany was the scene of repeated antisemitic campaigns aimed at counteracting this development. Until the mid-1920s, there was widespread public protest against these campaigns, with above all liberal, Social Democratic, and Jewish organizations—the Association for Defense against Antisemitism, the Reichsbanner Schwarz-Rot-Gold, the Central Association of German Citizens of the Jewish Faith, and both the Social Democratic Party and the Independent Social Democratic Party of Germany—playing an important role. In the second half of the 1920s, this protest abated. The failure of resistance to antisemitic agitation in this period was tied to a general decline of liberal forces in Germany, but also to an underestimation of the danger posed by the antisemitic parties and the lack of a new strategy in the face of so-called “Radau” antisemitism, with its violent penchant. Seemingly moderate antisemitic positions, advocating not violence but rather professional discrimination, now increasingly gained ground. In this framework, the National Socialist German Workers’ Party adopted a legalistic course, proposing legal measures for Jewish segregation. When these measures were enacted in the 1930s, they were largely accepted without comment by the non-Jewish German populace. Those intervening in favor of persecuted German Jews in the following years hardly had any supporting structures and acted largely alone.

description: A stochastic gravitational-wave background (SGWB) can arise from the superposition of many independent events. If the rate of events per unit time is sufficiently high, the resulting background is Gaussian, which is to say that it is characterized only by a gravitational-wave strain power spectrum. Alternatively, if the event rate is low, we expect a non-Gaussian background, characterized by intermittent sub-threshold bursts. Many experimentally accessible models of the SGWB, such as the SGWB arising from compact binary coalescences, are expected to be of this non-Gaussian variety. Primordial backgrounds from the early universe, on the other hand, are more likely to be Gaussian. Measuring the Gaussianity of the SGWB can therefore provide additional information about its origin. In this paper we introduce a novel maximum likelihood estimator that can be used to estimate the non-Gaussian component of an SGWB signature measured in a network of interferometers. This method can be robustly applied to spatially separated interferometers with colored, non-Gaussian noise. Furthermore, it can be cast as a generalization of the widely used stochastic radiometer algorithm.

description: Usable speech criteria are proposed to extract minimally corrupted speech for speaker identification (SID) in co-channel speech. In co-channel speech, either speaker can randomly appear as the stronger speaker or the weaker one at a time. Hence, the extracted usable segments are separated in time and need to be organized into speaker streams for SID. In this paper, we focus to organize extracted usable speech segment into a single stream for the same speaker by speaker assignment system. For this, we develop model-based speaker assignment method based on posterior probability and exhaustive search algorithm. Evaluation of this method is performed on TIMIT database. The system is evaluated on co-channel speech and results show a significant improvement.

description: Motivation: Detailed experimental knowledge of the level structure of light weakly bound nuclei is necessary to guide the development of new theoretical approaches that combine nuclear structure with reaction dynamics. Purpose: The resonant structure of 8B is studied in this work. Method: Excitation functions for elastic and inelastic 7Be+p scattering were measured using a 7Be rare isotope beam. Excitation energies ranging between 1.6 and 3.4 MeV were investigated. An R-matrix analysis of the excitation functions was performed. Results: New low-lying resonances at 1.9, 2.5, and 3.3 MeV in 8B are reported with spin-parity assignment 0+, 2+, and 1+, respectively. Comparison to the Time Dependent Continuum Shell (TDCSM) model and ab initio no-core shell model/resonating-group method (NCSM/RGM) calculations is performed. This work is a more detailed analysis of the data first published as a Rapid Communication. [J.P. Mitchell, et al, Phys. Rev. C 82, 011601(R) (2010)] Conclusions: Identification of the 0+, 2+, 1+ states that were predicted by some models at relatively low energy but never observed experimentally is an important step toward understanding the structure of 8B. Their identification was aided by having both elastic and inelastic scattering data. Direct comparison of the cross sections and phase shifts predicted by the TDCSM and ab initio No Core Shell Model coupled with the resonating group method is of particular interest and provides a good test for these theoretical approaches.

description: In 1676 Olaus Rømer presented the first observational evidence for a finite light velocity $\cem$. He formed his estimate by attributing the periodically varying discrepancy between the observed and expected occultation times of the Galilean satellite Io by its planetary host Jupiter to the time it takes light to cross Earth's orbital diameter. Given a stable celestial clock that can be observed in gravitational waves the same principle can be used to measure the propagation speed $\cgw$ of gravitational radiation. Space-based "LISA"-like detectors will, and terrestrial LIGO-like detectors may, observe such clocks and thus be capable of directly measuring the propagation velocity of gravitational waves. In the case of space-based detectors the clocks will be galactic close white dwarf binary systems; in the case of terrestrial detectors, the most likely candidate clock is the periodic gravitational radiation from a rapidly rotating non-axisymmetric neutron star. Here we evaluate the accuracy that may be expected of such a Rømer-type measurement of $\cgw$ by foreseeable future space-based and terrestrial detectors. For space-based, LISA-like detectors, periodic sources are plentiful: by the end of the first year of scientific operations a LISA-like detector will have measured $\cgw$ to better than a part in a thousand. Periodic sources may not be accessible in terrestrial detectors available to us in the foreseeable future; however, if such a source is detected then with a year of observations we could measure $\cgw$ to better than a part in a million.

description: The central nervous system (CNS) has specialised and diverse cell populations. Identifying cell-specific molecular signatures may reveal more comprehensive information about neurological pathways and CNS complexity. Glycosylation is the most common functional post-translation modification (PTM) in the brain and identifying cell-type dependent glycan features helps provide a better understanding of their role in brain cell intercellular interactions. In this study, we identified plasma membrane glycan features of three mammalian brain cell lines; BV2 (microglia), U87-MG (astrocytes) and differentiated SH-SY5Y (neurons) under lipopolysaccharide (LPS) stimulated inflammation. A panel of 9 lectins used here for histochemistry and fluorescence microscopy helps visually identify distinct cell-specific glycan features followed by quantification by FLD-HPLC and PGC-LC-MS/MS for released glycosaminoglycan disaccharides and N-glycans. Our results revealed cell type specific glycan expression, with cell selective binding of Sambucus nigra agglutinin (SNA) and Wisteria floribunda agglutinin (WFA) lectins. SNA lectin binding and LC-MS/MS revealed the absence of α-2,6 linked sialic acid glycans on U87-MG cells. BV2 microglia showed a significant decrease in the glycosaminoglycan, heparan sulphate over time under LPS inflammatory conditions. In summary, this study advances our knowledge of the complexity of brain cell glycan feature expression in a cell type specific and inflammation driven context.

description: GRO J0422+32 is a member of the class of low-mass X-ray binary (LMXB) sources, discovered during an outburst in 1992. Along the entire episode ($\sim 230$ days) a persistent power-law spectral component extending up to $\sim 1$ MeV was observed. These results suggest that non-thermal processes must be at work in the system. We apply a corona model to describe the spectrum of GRO J0422+32 during the flaring phase. We study relativistic particle interactions solving the transport equations for all type of particles self-consistently. We fit the electromagnetic emission during the plateau phase of the event and estimate the emission during an energetic episode, as well as the neutrino production. Our work leads to predictions that can be tested by the new generation of very high energy gamma-ray instruments.

description: This paper shows an innovative solution for distributing dynamic sensor data by using distributed caches. Our proposal is based on the concepts of service modularization and virtualization of network nodes made available by the NetServ hosting environment, which has been defined and implemented with the aim of extending the functions of the network nodes. Through a lab experiment involving tens of nodes, we have demonstrated a significant performance improvements in term of traffic saving and download time in comparison with a legacy, Internet-based, approach. Beyond this performance improvements, the proposed solution holds also functional improvements, in terms of dynamic deployment and easy integration with services making use of sensor data.

description: We consider several multiscale-in-time kinetic Monte Carlo models, in which some variables evolve on a fast time scale, while the others evolve on a slow time scale. In the first two models we consider, a particle evolves in a one-dimensional potential energy landscape which has some small and some large barriers, the latter dividing the state space into metastable regions. In the limit of infinitely large barriers, we identify the effective dynamics between these macro-states, and prove the convergence of the process towards a kinetic Monte Carlo model. We next consider a third model, which consists of a system of two particles. The state of each particle evolves on a fast time-scale while conserving their respective energy. In addition, the particles can exchange energy on a slow time scale. Considering the energy of the first particle, we identify its effective dynamics in the limit of asymptotically small ratio between the characteristic times of the fast and the slow dynamics. For all models, our results are illustrated by representative numerical simulations.
The drivers of AGN activity in galaxy clusters: AGN fraction as a function of mass and environment

description: [Abridged] We present an analysis of optical spectroscopically-identified AGN to M*+1 in a sample of 6 self-similar SDSS galaxy clusters at z=0.07. These clusters are specifically selected to lack significant substructure at bright limits in their central regions so that we are largely able to eliminate the local action of merging clusters on the frequency of AGN. We demonstrate that the AGN fraction increases significantly from the cluster centre to 1.5Rvirial, but tails off at larger radii. If only comparing the cluster core region to regions at ~2Rvirial, no significant variation would be found. We compute the AGN fraction by mass and show that massive galaxies (log(stellar mass)>10.7) are host to a systematically higher fraction of AGN than lower mass galaxies at all radii from the cluster centre. We attribute this deficit of AGN in the cluster centre to the changing mix of galaxy types with radius. We use the WHAN diagnostic to separate weak AGN from `retired' galaxies in which the main ionization mechanism comes from old stellar populations. These retired AGN are found at all radii, while the mass effect is much more pronounced: we find that massive galaxies are more likely to be in the retired class. Further, we show that our AGN have no special position inside galaxy clusters - they are neither preferentially located in the infall regions, nor situated at local maxima of galaxy density. However, we find that the most powerful AGN (with [OIII] equivalent widths

description: Astrometric detection and mass determination of Earth-mass exoplanets requires sub-microarcsec accuracy, which is theoretically possible with an imaging space telescope using field stars as an astrometric reference. The measurement must however overcome astrometric distortions which are much larger than the photon noise limit. To address this issue, we propose to generate faint stellar diffraction spikes using a two-dimensional grid of regularly spaced small dark spots added to the surface of the primary mirror (PM). Accurate astrometric motion of the host star is obtained by comparing the position of the spikes to the background field stars. The spikes do not contribute to scattered light in the central part of the field and therefore allow unperturbed coronagraphic observation of the star's immediate surrounding. Because the diffraction spikes are created on the PM and imaged on the same focal plane detector as the background stars, astrometric distortions affect equally the diffraction spikes and the background stars, and are therefore calibrated. We describe the technique, detail how the data collected by the wide-field camera are used to derive astrometric motion, and identify the main sources of astrometric error using numerical simulations and analytical derivations. We find that the 1.4 m diameter telescope, 0.3 sq.deg field we adopt as a baseline design achieves 0.2 microarcsec single measurement astrometric accuracy. The diffractive pupil concept thus enables sub-microarcsec astrometry without relying on the accurate pointing, external metrology or high stability hardware required with previously proposed high precision astrometry concepts.

description: Ultrafast broadband transient reflectivity experiments are performed to study the interplay between the non-equilibrium dynamics of the pseudogap and the superconducting phases in Bi$_{2}$Sr$_{2}$Ca$_{0.92}$Y$_{0.08}$Cu$_{2}$O$_{8+δ}$. Once superconductivity is established the relaxation of the pseudogap proceeds $\sim$ 2 times faster than in the normal state, and the corresponding transient reflectivity variation changes sign after $\sim$ 0.5 ps. The results can be described by a set of coupled differential equations for the pseudogap and for the superconducting order parameter. The sign and strength of the coupling term suggest a remarkably weak competition between the two phases, allowing their coexistence.

Top-flavored dark matter and the forward-backward asymmetry

name: Tulin, Sean
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We propose a simple model where dark matter (DM) carries top flavor and couples to the Standard Model through the top quark within a framework of minimal flavor violation (MFV). Top-flavored DM can explain the anomalous top forward-backward asymmetry observed at the Tevatron, while remaining consistent with other top observables at colliders. By virtue of its large coupling to top, DM acquires a sizable loop coupling to the Z boson, and the relic density is set by annihilation through the Z. We also discuss contraints from current direct detection searches, emphasizing the role of spin-dependent searches to probe this scenario.

description: Coupled dynamical systems with one slow element and many fast elements are analyzed. By averaging over the dynamics of the fast variables, the adiabatic kinetic branch is introduced for the dynamics of the slow variable in the adiabatic limit. The dynamics without the limit are found to be represented by stochastic switching over these branches mediated by the collective chaos of the fast elements, while the switching frequency shows a complicated dependence on the ratio of the two timescales with some resonance structure. The ubiquity of the phenomena in the slow--fast dynamics is also discussed.
