Synchrony-optimized Networks of Non-identical Kuramoto Oscillators
Creators: name: Brede, Markus
Publisher: name: arXiv
Year: 2008
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: In this letter we discuss a method for generating synchrony-optimized coupling architectures of Kuramoto oscillators with a heterogeneous distribution of native frequencies. The method allows us to relate the properties of the coupling network to its synchronizability. These relations were previously only established from a linear stability analysis of the identical oscillator case. We further demonstrate that the heterogeneity in the oscillator population produces heterogeneity in the optimal coupling network as well. Two rules for enhancing the synchronizability of a given network by a suitable placement of oscillators are given: (i) native frequencies of adjacent oscillators must be anti-correlated and (ii) frequency magnitudes should positively correlate with the degree of the node they are placed at.
Eine andere historische Subjektivierung

Publisher: name: Österreichische Zeitschrift für Geschichtswissenschaften

description: In focusing on Jacques Rancière and Walter Benjamin, the main concern of this essay is to outline an alternative concept of the historical sub­ject. As I assume, subjectivity primarily forms itself in being oriented to that which is incommensurable, namely, the radical positivity of being itself. First, I show that Rancière’s concept of ‘equality’ can be read in terms of this basic formative movement. Equality enables political claims and, accordingly, poli­tical subjecti cation while, ultimately, remaining irredeemable. Yet, I do not agree with the aporetic character of equality in Rancière, which, in my view, creates a perpetuation of injustice. In order to overcome it, I draw on Benjamin and demonstrate that, in implicitly referring to redemption, the irredeemable has a positive content. In a relative way, it can be restored when­ ever the remembrance of past suffering is incorporated into new claims of justice. Historical subjects originate in this merging of present and past.

description: Abstract: Nematic liquid crystal elastomers (LCE) exhibit unique mechanical properties, placing them in a category distinct from other viscoelastic systems. One of their most celebrated properties is the ‘soft elasticity’, leading to a wide plateau of low, nearly-constant stress upon stretching, a characteristically slow stress relaxation, enhanced surface adhesion, and other remarkable effects. The dynamic soft response of LCE to shear deformations leads to the extremely large loss behaviour with the loss factor tanδ approaching unity over a wide temperature and frequency ranges, with clear implications for damping applications. Here we investigate this effect of anomalous damping, optimising the impact and vibration geometries to reach the greatest benefits in vibration isolation and impact damping by accessing internal shear deformation modes. We compare impact energy dissipation in shaped samples and projectiles, with elastic wave transmission and resonance, finding a good correlation between the results of such diverse tests. By comparing with ordinary elastomers used for industrial damping, we demonstrate that the nematic LCE is an exceptional damping material and propose directions that should be explored for further improvements in practical damping applications.
Similarity solution of a Fokker-Planck equation with a moving, absorbing boundary
Creators: name: Lee, Richard Tsan Ming
Publisher: name: University of British Columbia
Year: 2010

description: A one parameter Lie group of transformations is used to derive a closed form similarity solution of the equation: [See Thesis for Equation]. A simple expression for the first passage time distribution of the general Fokker-Planck (Kolraogorov forward) equation in an irregular domain is derived, which is subsequently used to find the first passage time distributions of four equivalent problems. A new distribution is found. A small time asymptotic expansion of the integral solution of (*) is calculated in order to be pieced together to form the solution for a more general r (t). Examining the feasibility of this method, we find that it is equivalent to a simple application of Taylor expansions, and it is not better than the powerful method of transforming the irregular domain to a regular one and applying some explicit schemes. Convergence and Stability criteria are derived for an explicit method which admits an arbitrary (t).

description: A Bayesian analysis of the possible behaviors of the dense matter equation of state informed through recent LIGO-Virgo as well as NICER measurements reveals that all the present observations are compatible with a fully nucleonic hypothesis for the composition of dense matter, even in the core of the most massive pulsar PSR J0740+6620. Under the hypothesis of a nucleonic composition, we extract the most general behavior of the energy per particle of symmetric matter and density dependence of the symmetry energy, compatible with the astrophysical observations as well as our present knowledge of low energy nuclear physics from effective field theory predictions and experimental nuclear mass data. These results can be used as a null hypothesis to be confronted with future constraints on dense matter to search for possible exotic degrees of freedom.

description: The ferromagnetic (FM) nature of the metallic LaCo$_2$P$_2$ was investigated with the positive muon spin rotation, relaxation and resonance ($μ^+$SR) technique. Transverse and zero field $μ^+$SR measurements revealed that the compound enters a long range FM ground state at $T_{\rm C}=130.91(65)$~K, consistent with previous studies. Based on the reported FM structure, the internal magnetic field was computed at the muon sites, which were predicted with first principles calculations. The computed result agree well with the experimental data. Moreover, although LaCo$_2$P$_2$ is a paramagnet at higher temperatures $T>160$~K, it enters a short range ordered (SRO) magnetic phase for $T_{\rm C}

Procedural justice checklist
Randomised controlled trial
Scalable interventions
Counterterrorism
Legitimacy

description: Funder: University of Cambridge
description: Abstract: Objectives: When it comes to interviewing suspected terrorists, global evidence points to harsh interrogation procedures, despite the likelihood of false positives. How can the state maintain an effective counterterrorism policy while simultaneously protecting civil rights? Until now, the shroud of secrecy of “national security” practices has thwarted attempts by researchers to test apparatuses that engender fair interrogation procedures. The present study aims to test one approach: the use of a “procedural justice checklist” (PJ Checklist) in interviews of suspected terrorists by counterterrorism police officers in port settings. Methods: Using a clustered randomized controlled field test in a European democracy, we measure the effect of implementing Procedural Justice (PJ) Checklists in counterterrorism police settings. With 65 teams of officers randomly-assigned into treatment and control conditions, we compare post-interrogation surveys of suspects (n = 1418) on perceptions of legitimacy; obligations to obey the law; willingness to cooperate with the police; effectiveness of counterterrorism measures; distributive justice; feelings of social resistance to the state; and PJ. A series of multi-level linear, logistic, and ordered logit regression models are used to estimate the treatment effect, with Hedges’ g and odds ratios used for effect sizes. Results: When compared with control conditions, implementing a policy of PJ Checklist causes statistically significant and large enhancement in all measured dimensions, including the willingness of suspects to obey the law (g = 1.022 [0.905, 1.138]), to cooperate with the police (g = 1.118 [0.999, 1.238]), distributive justice (g = 0.993 [0.880, 1.106]), effectiveness (g = 1.077 [0.959, 1.195]), procedural justice (g = 1.044 [0.930, 1.158]), and feelings of resistance towards the state (g = − 0.370 [− 0.259, − 0.482]). Conclusions: PJ checklists offer a simple, scalable means of improving how state agents interact with terrorism suspects. The police can use what is evidently a cost-effective tool to enhance legitimacy and cooperation with the police, even in a counterterrorism environment.

description: This article provides a sociological explanation for the global emergence of Slavoj Žižek as a public intellectual. It presents an integrative account encompassing both personal and institutional aspects. Drawing on positioning theory and performative frameworks, the article contributes to the sociology of intellectuals, as well as to the vast ‘Žižek-literature’ that focuses on his philosophical content or political activities. We analyse the distinctiveness of Žižek’s performances, arguing that Žižek acts as a ‘sacrificial intellectual’: he plays ‘the fool’ and relies on irony to undermine the traditional role of the authoritative intellectual. Within the context of the digital public sphere and declining intellectual authority, Žižek’s unique form of positioning has been particularly effective and has contributed to his celebrity status.

Personal relative deprivation and pro-environmental intentions

description: Personal relative deprivation (PRD; the belief that one is worse off than other people who are similar to oneself) is associated with a reduced willingness to delay gratification, lower prosociality, and increased materialism. These results suggest that PRD may play a role in shaping people’s willingness to act to protect the natural environment. We report 3 studies that investigate a possible link between PRD and pro-environmental intentions (ENV). Study 1 was an exploratory study using a US sample; Studies 2 and 3 were pre-registered replications using UK and US samples, respectively. In each study, participants self-reported PRD and ENV; they also indicated their subjective social status (where they come on a national “ladder” of social class) and reported their income, education, age, and gender/sex. All three studies found a negative correlation between PRD and ENV. However, multiple regression analyses in which ENV was regressed on PRD and all other variables simultaneously indicated that the unique effect of PRD was small and, for Studies 2 and 3, the 95% confidence intervals included zero. No other variable emerged as a clear unique predictor across all three studies. The data suggest that PRD may be associated with reduced intention to act pro-environmentally, but the causal status of this association, and its relationship to other demographic and social-status variables, remains a topic for further research.

description: Space-based interferometric gravitational wave instruments such as the ESA/NASA Laser Interferometer Space Antenna (LISA) observe gravitational waves by measuring changes in the light travel time between widely-separated spacecraft. One potential noise source for these instruments is interaction with the solar wind, in particular the free electrons in the interplanetary plasma. Variations in the integrated column density of free electrons along the laser links will lead to time-of-flight delays which directly compete with signals produced by gravitational waves. In this paper we present a simplified model of the solar plasma relevant for this problem, anchor key parameters of our model using data from the NASA \emph{Wind}/SWE instrument, and derive estimates for the effect in the LISA measurement. We find that under normal solar conditions, the gravitational-wave sensitivity limit from the free-electron effect is smaller than other noise sources that are expected to limit LISA's sensitivity.

description: We have numerically studied a non-adiabatic charge transport in the quantum Hall system pumped by a magnetic flux, as one of the simplest theoretical realizations of non-adiabatic Thouless pumping. In the adiabatic limit, a pumped charge is quantized, known as Laughlin's argument in a cylindrical lattice. In a uniform electric field, we obtained a formula connecting quantized pumping in the adiabatic limit and no-pumping in the sudden limit. The intermediate region between the two limits is determined by the Landau gap. A randomness or impurity effect is also discussed.

The device is based on existing sound velocity profilers. It was proposed to replace the TDC-GP22 converters used in the sound speed meter ISZ-1 with more advanced modern modified converters TDC-GP30, which can significantly improve the accuracy of measuring the amplitude of the reflected acoustic signal. The programs for processing signals from the primary acoustic transducer have been developed. The model of the device passed preliminary tests.

description: We present here a model for multivalent diffusive transport whereby a central point-like hub is coupled to multiple feet, which bind to complementary sites on a two-dimensional landscape. The available number of binding interactions is dependent on the number of feet (multivalency), and on their allowed distance from the central hub (span). Using Monte Carlo simulations that implement the Gillespie algorithm, we simulate multivalent diffusive transport processes for 100 distinct walker designs. Informed by our simulation results we derive an analytical expression for the diffusion coefficient of a general multivalent diffusive process as a function of multivalency, span, and dissociation constant Kd. Our findings can be used to guide experimental design of multivalent transporters, in particular providing insight into how to overcome trade-offs between diffusivity and processivity.

description: The magnetic damping constant is a critical parameter for magnetization dynamics and the efficiency of memory devices and magnon transport. Therefore, its manipulation by electric fields is crucial in spintronics. Here, we theoretically demonstrate the voltage-control of magnetic damping in ferro- and ferrimagnetic-insulator (FI)/topological-insulator (TI) bilayers. Assuming a capacitor-like setup, we formulate an effective dissipation torque induced by spin-charge pumping at the FI/TI interface as a function of an applied voltage. By using realistic material parameters, we find that the effective damping for a FI with 10nm thickness can be tuned by one order of magnitude under the voltage with 0.25V. Also, we provide perspectives on the voltage-induced modulation of the magnon spin transport on proximity-coupled FIs.

description: There is a transhistoric dimension in Rancière’s oeuvre that claims a capacity of the people to use speech and words for their emancipatory and thus political purposes. People are able to make history because they are “literate” beings. But history as history and as historiography alike is also a key element in his thought of the literate and political being in so far as it has a historic dimension, has itself a history. The turning point in the history of his- toriography is the revolution of literature, which changes completely the relationship between acting and telling stories, between what is worthy to narrate and what is a story. In the 18th century the revolution of literature is a condition for scientific historiography. Rancière’s own historiography of 19th century workers tries to put forward another kind of historiography that does not reduce the event and the new to its historical conditions, refusing the expression-model of modern historiography.

description: Hard x-ray photoemission and optical spectroscopies have been performed on YbS and Yb metal to determine the precise $f$-electron occupation. A comparison of the photoemission spectra with the energy loss functions in bulk and surface, obtained from optical reflectivity, enables us to distinguish between the energy loss satellite of Yb$^{2+}$ peak and Yb$^{3+}$ multiplet. The results clearly indicate a purely divalent Yb state except for the surface of YbS. We demonstrate that the present method is highly reliable in identifying the electronic structure and the mean valence in $f$-electron systems.

A model for optimal infrastructure investment in boom towns

description: A linear model to determine the optimal policy for investment in social infrastructure is formulated and its solution is obtained using the Maximum Principle. The unique solution is characterized by a-bang-bang control, with only one interval of investment in social capital, and the endpoints of this interval can be numerically determined, given values for the parameters of the model. A generalization of the model which allows instantaneous jumps in the level of social capital is also analyzed, and the solution to the modified problem is shown to be a uniquely determined impulse control. The final extension of the model allows us to determine an upper bound for the optimal time horizon.

description: In this work, we consider different forms of relativistic perfect fluid Lagrangian densities, that yield the same gravitational field equations in General Relativity. A particularly intriguing example is the case with couplings of the form $[1+f_2(R)]{\cal L}_m$, where $R$ is the scalar curvature, which induces an extra force that depends on the form of the Lagrangian density. It has been found that, considering the Lagrangian density ${\cal L}_m = p$, where $p$ is the pressure, the extra-force vanishes. We argue that this is not the unique choice for the matter Lagrangian density, and that more natural forms for ${\cal L}_m$ do not imply the vanishing of the extra-force. Particular attention is paid to the impact on the classical equivalence between different Lagrangian descriptions of a perfect fluid.

description: Magnonics is now an attractive field which focuses on the dynamic characteristics of magnons, a kind of quasiparticles in magnetic media, and attempt to apply magnons for functional devices. In order to construct magnon based devices, it is necessary to fabricate materials with specific and tunable magnon bands and band gaps. Skyrmion based magnonic crystals is one of the most suitable materials which possess periodical skyrmion structure and show applicative magnon bands and band gaps. In this review, we provide an overview over recent theoretical and experimental research on skyrmion based magnonic crystals. We will firstly provide an introduction of magnonic crystals and magnetic skyrmion. And then we will show the theoretical and experimental progress on skyrmion based magnonic crystals and their magnon band characteristics. At the end, we will give an outlook and perspectives of new fascinating fields on topological nontrivial magnon modes, as well as hybrid and quantum magnonic phenomena of skyrmion based magnonic crystals.

description: The analysis of the positioning of regional organizations in the new international security context has led to several arguments in favor of the legitimation of a regional security framework. This stems from the recognition of the failure of traditional UN mechanisms, which restrict security issues to direct military threats against states, and the need to adapt these mechanisms to conflicting realities. We have highlighted the scope of this undertaking by presenting the conceptual framework of the regionalization of crisis and conflict management, while remaining attentive to the potential contradictions that this framework can generate. These contradictions include political barriers, precise parameters of action, defined modes of intervention, and strategies for circumventing regional instruments, symbolized by the divergences between the autonomous actions of regional organizations, in particular Africa, and the need for complementarity with the UN. Drawing on the experience of the African continent, where security issues, in particular, place this region at the centre of global security debates, we have outlined the nature and extent of security issues that prompt states to redefine security perceptions in favor of regionalizing the management of African conflicts. In this context, African regional organizations have expanded their field of action to regional peace and security, overcoming their inherent difficulties through lessons learned from their failures and successes, supported by significant statutory and institutional changes at regional level. Africa, like other parts of the world, has attempted to establish several security mechanisms under the UN Charter framework.
Reconstruction of the primordial fluctuation spectrum from the five-year WMAP data by the cosmic inversion method with band-power decorrelation analysis

description: The primordial curvature fluctuation spectrum is reconstructed by the cosmic inversion method using the five-year WMAP data of the cosmic microwave background temperature anisotropy. We apply the covariance matrix analysis and decompose the reconstructed spectrum into statistically independent band-powers. The statistically significant deviation from a simple power-law spectrum suggested by the analysis of the first-year data is not found in the five-year data except possibly at one point near the border of the wavenumber domain where accurate reconstruction is possible.

Universal features of canonical phonon angular momentum without time-reversal symmetry

description: It is known that phonons have angular momentum, and when the time-reversal symmetry (TRS) is broken, the total phonon angular momentum in the whole system becomes nonzero. In this paper, we propose that as an angular momentum of phonons for a crystal without TRS, we need to consider the canonical angular momentum, as opposed to the kinetic angular momentum in previous works. Next, we show that the angular momentum of phonons without TRS exhibits universal behaviors near the $Γ$ point. We focus on in-plane oscillations in two-dimensional crystals as an example. By breaking the TRS, one of the acoustic phonon branches at the $Γ$ point acquires a gap. We show that the angular momentum of its acoustic phonon with a gap has a peak with the height $\pm \hbar$ regardless of the details of the system. From this, we find that this peak height changes discontinuously by changing the sign of the TRS-breaking parameter.

The fundamental surgery theorem and the classification of manifolds
Creators: name: Cameron, Richard Bruce
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this paper is to present a survey of some important results in the classification of differentiable manifolds. We begin with the Poincaré conjecture and its partial solution using the h-cobordism theorem. We review next the work of Kervaire and Milnor, concerned with the diffeomorphism classes of homotopy spheres. The surgery problem developed from their work, and we present its solution in the simply-connected case, by Browder. This solution amounts to the surgery invariant theorem, the fundamental surgery theorem and associated results. We end our discussion with the plumbing theorem, and several important classification theorems of Browder, Novikov and Wall.

description: In this paper, we develop a simple method for the reconstruction of the string-inspired dark energy model with the lagrangian $ {\cal L} = -V (ϕ) \sqrt{1 - α' {\nabla}_μ ϕ\nabla^μ ϕ+ β' ϕ\Box ϕ} $ given by Cai et. al., which may allow the equation-of-state parameter cross the cosmological constant boundary $ (w=-1) $. We reconstruct this model in the light of three forms of parametrization for dynamical dark energy.

Noise scaling in SQUID arrays

description: We numerically investigate the noise scaling in high-Tc commensurate 1D and 2D SQUID arrays. We show that the voltage noise spectral density in 1D arrays violates the scaling rule of ~1/Np for the number Np of Josephson junctions in parallel. In contrast, in 2D arrays with Ns 1D arrays in series, the voltage noise spectral density follows more closely the expected scaling behaviour of ~Ns/Np. Additionally, we reveal how the flux and magnetic field rms noise spectral densities deviate from their expected ~(NsNp)^(-1/2) scaling and discuss their implications for designing low noise magnetometers.

description: In this paper, we investigate the generalized seniority scheme and the validity of Generalized Seniority Schmidt Model in and around the $Z=82$ semi-magic region. A consistently same multi-j configuration is used to explain all the nuclear spectroscopic properties such as $g-$factors, $Q-$moments and $B(E2)$ trends for the ${13/2}^+$, ${12}^+$ and ${33/2}^+$ isomers in all the three Hg, Pb and Po isotopic chains. The inverted parabolic $B(E2)$ trends for the first $2^+$ states in Hg, Pb and Po isotopes are also explained using the generalized seniority scheme. A comparison with the experimental data is presented, wherever possible, and future possibilities are suggested.

description: Vienna in the period 1760–1823 was part of an abundant and expansive European world of goods. This article examines a specific cluster of goods, namely body linen, which encompassed underclothes and accessories that people wore in public and served both aesthetic and practical functions. Using a quantitative analysis of the Viennese probate inventories, this essay examines the trends of ownership of these goods in the Viennese middle and lower social strata. It focuses on the differences in number and material, and associates these trends with European-wide patterns of ownership and consumption. Moreover, it shows how variations in the ownership of body linen affect certain aspects of its social role: its influence on clothing luxury and respectable appearance, and its role in new ideals of cleanliness and hygiene.

description: We investigate the damping of the baryon acoustic oscillations (BAO) signature in the matter power spectrum due to the quasi-nonlinear clustering of density perturbations. On the basis of the third order perturbation theory, we construct a fitting formula of the damping in an analytic way. This demonstrates that the damping is closely related with the growth factor and the amplitude of the matter power spectrum. Then, we investigate the feasibility of constraining the growth factor through a measurement of the damping of the BAO signature. An extension of our formula including higher order corrections of density perturbations is also discussed.
