description: In this essay, I want to look at the related issues regarding the debate over the naming of the East Sea/Sea of Japan and the territorial claim over Dokdo islets. Both issues, in their different ways, represent a colonial legacy in a postcolonial world. Their resolution highlights the need for a postcolonial sensitivity and more positive global citizenship.

description: We determine the gas-phase oxygen abundance for a sample of 695 galaxies and H II regions with reliable detections of [O III]4363, using the temperature-sensitive Te method. Our aims are to estimate the validity of empirical methods such as R23, R23-P, log([N II]/Halpha) (N2), log[([O III]/Hbeta)/([N II]/Halpha)] (O3N2), and log([S II]/Halpha) (S2), and especially to re-derive (or add) the calibrations of R23, N2, O3N2 and S2 indices for oxygen abundances on the basis of this large sample of galaxies with Te-based abundances. We select 531 star-forming galaxies from the SDSS-DR4, and 164 galaxies and H II regions from literature for such study. Their (O/H) abundances obtained from Te are within 7.1<12+log(O/H)<8.5 mostly. For roughly half of the SDSS samples, the Bayesian abundances obtained by the MPA/JHU group are overestimated by ~0.34 dex compared with the Te-based (O/H) measurements, possibly due to the treatment of nitrogen enrichment in the models they used. R23 and R23-P methods systematically overestimate the O/H abundance by a factor of ~0.20 dex and ~0.06 dex, respectively. The N2 index, rather than the O3N2 index, provides relatively consistent O/H abundances with the Te-method, but with some scatter. The relations of N2, O3N2, S2 with log(O/H) are consistent with the photoionization model calculations of Kewley & Doptita (2002), but R23 does not match well. Then we derive analytical calibrations for O/H from R23, N2, O3N2 and S2 indices on the basis of this large sample of galaxies, especially including the excitation parameter P as an additional parameter in the N2 calibration. These can be used as calibration references in the future studies about metallicities of galaxies.

description: The purpose of this ethnographic study was to learn about education for girls and women in Syria. There is in the west a stereotype of Arab women as undereducated and without rights. This view of Muslim women ignores national differences, changes in the status of women, differences within the country, and often confuses religion and culture. The research questions were as follows. What are the educational opportunities for women and girls in Syria? How have the opportunities changed? Finally, how have women benefited from the changes in educational opportunities? I saw evidence of vast increases in opportunity for women since 1946. There were also educational reforms since Bashar al-Asad became President in 2000. For eight weeks, I lived in a town outside of Damascus during May, June and July of 2006. I observed and participated in daily family and other social routines. Here, I focused on women's points of view and their stories of educational experiences and successes or failures. I visited private tutors, classrooms, campuses of schools, the Ministry of Education and Damascus University.  I observed vocational, adult education, and religion classes. Interviews were conducted with schoolchildren, women of all educational levels, and older women who have lived through great changes in educational opportunity since Syrian independence in 1946.

description: Error exponents characterize the exponential decay, when increasing message length, of the probability of error of many error-correcting codes. To tackle the long standing problem of computing them exactly, we introduce a general, thermodynamic, formalism that we illustrate with maximum-likelihood decoding of low-density parity-check (LDPC) codes on the binary erasure channel (BEC) and the binary symmetric channel (BSC). In this formalism, we apply the cavity method for large deviations to derive expressions for both the average and typical error exponents, which differ by the procedure used to select the codes from specified ensembles. When decreasing the noise intensity, we find that two phase transitions take place, at two different levels: a glass to ferromagnetic transition in the space of codewords, and a paramagnetic to glass transition in the space of codes.

description: We analyse 55 ks of Chandra X-ray observations of the Galactic globular cluster M13. Using the latest radio timing positions of six known millisecond pulsars (MSPs) in M13 from Wang et al. (2020), we detect confident X-ray counterparts to five of the six MSPs at X-ray luminosities of $L_X$(0.3-8 keV)$\sim 3 \times 10^{30} - 10^{31}~{\rm erg~s^{-1}}$, including the newly discovered PSR J1641+3627F. There are limited X-ray counts at the position of PSR J1641+3627A, for which we obtain an upper limit $L_X<1.3 \times 10^{30}~{\rm erg~s^{-1}}$. We analyse X-ray spectra of all six MSPs, which are well-described by either a single blackbody or a single power-law model. We also incorporate optical/UV imaging observations from the Hubble Space Telescope (HST) and find optical counterparts to PSR J1641+3627D and J1641+3627F. Our colour-magnitude diagrams indicate the latter contains a white dwarf, consistent with the properties suggested by radio timing observations. The counterpart to J1641+3627D is only visible in the V band; however, we argue that the companion to J1641+3627D is also a white dwarf, since we see a blackbody-like X-ray spectrum, while MSPs with nondegenerate companions generally show non-thermal X-rays from shocks between the pulsar and companion winds. Our work increases the sample of known X-ray and optical counterparts of MSPs in globular clusters.

description: Time reversal of acoustic waves can be achieved efficiently by the persistent control of excitations in a finite region of the system. The procedure, called Time Reversal Mirror, is stable against the inhomogeneities of the medium and it has numerous applications in medical physics, oceanography and communications. As a first step in the study of this robustness, we apply the Perfect Inverse Filter procedure that accounts for the memory effects of the system. In the numerical evaluation of such procedures we developed the Pair Partitioning method for a system of coupled oscillators. The algorithm, inspired in the Trotter strategy for quantum dynamics, obtains the dynamic for a chain of coupled harmonic oscillators by the separation of the system in pairs and applying a stroboscopic sequence that alternates the evolution of each pair. We analyze here the formal basis of the method and discuss his extension for including energy dissipation inside the medium.

description: We present the results of a high-resolution imaging survey of 22 brown dwarfs and very low mass stars in the nearby (~145 pc) young (~1-2 Myr) low-density star-forming region Taurus-Auriga. We obtained images with the Advanced Camera for Surveys/High Resolution Channel on HST through the F555W (V), F775W (i'), and F850LP (z') filters. This survey confirmed the binarity of MHO-Tau-8 and discovered a new candidate binary system, V410-Xray3, resulting in a binary fraction of 9+/-5% at separations >4 AU. Both binary systems are tight (<10 AU) and they possess mass ratios of 0.75 and 0.46, respectively. The binary frequency and separations are consistent with low-mass binary properties in the field, but the mass ratio of V410-Xray3 is among the lowest known. We find that the binary frequency is higher for very low mass stars and high-mass brown dwarfs than for lower-mass brown dwarfs, implying either a decline in frequency or a shift to smaller separations for the lowest mass binaries. Combining these results with multiplicity statistics for higher-mass Taurus members suggests a gradual decline in binary frequency and separation toward low masses. The implication is that the distinct binary properties of very low-mass systems are set during formation and that the formation process is similar to the process which creates higher-mass stellar binaries, but occurs on a smaller scale. We show that there are no planets or very low-mass brown dwarfs with mass >3 M_J at projected separation >40 AU orbiting any of the Taurus members in our sample. We identify several BDs with significant (>1 mag) V-band excesses. The excesses appear to be correlated with signatures of accretion, and if attributed to accretion luminosity, may imply mass accretion rates several orders of magnitude above those inferred from line-profile analyses.

Excess of Ca (and Sc) produced in globular cluster multiple populations: a first census in 77 Galactic globular clusters

description: Multiple stellar populations in globular clusters (GCs) are distinct by their different abundances of light elements. The abundance anti-correlations point towards a nucleosynthesis origin due to high-temperature H burning, but it remains to be assessed which type of stars altered primordial abundances in GCs. In particular, the regime at very high temperature that shapes the variations in potassium as well as calcium and scandium, which has been detected in a few notable cases such as NGC 2419 and NGC 2808, is still poorly explored. We started a systematic search for excess of Ca (and Sc) in GC stars with respect to the level of unmodified field stars. Statistically robust evidence of such excess was found in a small number of GCs (NGC 4833, NGC 6715, NGC 6402, NGC 5296, NGC 5824, and NGC 5139/omega Centauri) that join the previously known two clusters. For the first time we show that NGC 4833 is likely to host anti-correlated K and Mg abundances. All these GCs are among the most massive ones in the Galaxy. We found that the fraction of stars with Ca enhancement at 3sigma above the field star distribution is a multivariate function of the GC mass and metallicity, as in other manifestations of the multiple population phenomenon in GCs. We argue that these alterations in only a few GCs can be reproduced by two different channels: either a class of ordinary stars, that is common to all GCs, acts only in particular environments, or an on-off mechanism is generated by the occurrence of a peculiar type of stars (or lack of such stars). Hot bottom burning in asymptotic giant branch stars in the low-metallicity regime is a good candidate for the first class. Alternatively, a metallicity dependence is also expected for supermassive stars, which are predicted to preferentially form in massive GCs. (abridged).

description: Introduction Les sports overhead engendrent des atteintes du complexe de l’épaule, notamment au niveau de la cinématique de la scapula et de l’activité musculaire périscapulaire. Le taping est un adjuvant thérapeutique souvent utilisé pour des douleurs d’épaule, mais son action précise sur la scapula reste encore à définir. Objectif L’objectif de ce travail est d’évaluer, chez des sportifs overhead avec épaule douloureuse, les effets d’un tape rigide et élastique de la scapula sur sa cinématique et l’activité de ses muscles. Méthodologie Les bases de données PubMed, CINAHL, PEDro, Cochrane et OvidSP ont été consultées entre août 2018 et janvier 2019. Trois articles ont été retenus et analysés avec la grille McMaster. Les outcomes évalués ont été la cinématique de la scapula et l’activité musculaire périscapulaire. Résultats Les tapes élastique et placebo améliorent significativement le tilt postérieur et la sonnette latérale, elle-même également améliorée avec du tape rigide. Aucun effet du taping n’est trouvé sur les rotations de la scapula. Pour l’activité musculaire, des effets significatifs du tape élastique sur le trapèze inférieur et du tape placebo sur le trapèze supérieur sont trouvés. Le tape rigide améliore le début d’activité des trapèzes moyen, inférieur et du dentelé antérieur. Conclusion Malgré ces résultats sur la cinématique de la scapula et l’activité musculaire périscapulaire, ces derniers sont insuffisants pour valider leur pertinence clinique. Des études de meilleures qualité méthodologique sont encore nécessaires.

description: Combining satellite imagery with machine learning (SIML) has the potential to address global challenges by remotely estimating socioeconomic and environmental conditions in data-poor regions, yet the resource requirements of SIML limit its accessibility and use. We show that a single encoding of satellite imagery can generalize across diverse prediction tasks (e.g. forest cover, house price, road length). Our method achieves accuracy competitive with deep neural networks at orders of magnitude lower computational cost, scales globally, delivers label super-resolution predictions, and facilitates characterizations of uncertainty. Since image encodings are shared across tasks, they can be centrally computed and distributed to unlimited researchers, who need only fit a linear regression to their own ground truth data in order to achieve state-of-the-art SIML performance.
MHD versus kinetic effects in the solar coronal heating: a two stage mechanism

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Using Particle-In-Cell simulations i.e. in the kinetic plasma description the discovery of a new mechanism of parallel electric field generation was recently reported. Here we show that the electric field generation parallel to the uniform unperturbed magnetic field can be obtained in a much simpler framework using the ideal magnetohydrodynamics (MHD) description. In ideal MHD the electric field parallel to the uniform unperturbed magnetic field appears due to fast magnetosonic waves which are generated by the interaction of weakly non-linear Alfvén waves with the transverse density inhomogeneity. In the context of the coronal heating problem a new {\it two stage mechanism} of plasma heating is presented by putting emphasis, first, on the generation of parallel electric fields within an {\it ideal MHD} description directly, rather than focusing on the enhanced dissipation mechanisms of the Alfvén waves and, second, dissipation of these parallel electric fields via {\it kinetic} effects. It is shown that for a single Alfvén wave harmonic with frequency $ν= 7$ Hz, and longitudinal wavelength $λ_A = 0.63$ Mm for a putative Alfvén speed of 4328 km s$^{-1}$, the generated parallel electric field could account for 10% of the necessary coronal heating requirement. We conjecture that wide spectrum (10$^{-4}-10^3$ Hz) Alfvén waves, based on the observationally constrained spectrum, could provide the necessary coronal heating requirement. By comparing MHD versus kinetic results we also show that there is a clear indication of the {\it anomalous resistivity} which is 100s of times greater than the classical Braginskii value.

description: Let $Γ$ be a finite connected graph. The (unlabelled) configuration space $UC^n Γ$ of $n$ points on $Γ$ is the space of $n$-element subsets of $Γ$. The $n$-strand braid group of $Γ$, denoted $B_nΓ$, is the fundamental group of $UC^n Γ$. We use the methods and results of our paper "Discrete Morse theory and graph braid groups" to get a partial description of the cohomology rings $H^*(B_n T)$, where $T$ is a tree. Our results are then used to prove that $B_n T$ is a right-angled Artin group if and only if $T$ is linear or $n<4$. This gives a large number of counterexamples to Ghrist's conjecture that braid groups of planar graphs are right-angled Artin groups.

description: In this article we give an expository account of the holomorphic motion theorem based on work of Màñé-Sad-Sullivan, Bers-Royden, and Chirka. After proving this theorem, we show that tangent vectors to holomorphic motions have $|ε\log ε|$ moduli of continuity and then show how this type of continuity for tangent vectors can be combined with Schwarz's lemma and integration over the holomorphic variable to produce Hölder continuity on the mappings. We also prove, by using holomorphic motions, that Kobayashi's and Teichmüller's metrics on the Teichmüller space of a Riemann surface coincide. Finally, we present an application of holomorphic motions to complex dynamics, that is, we prove the Fatou linearization theorem for parabolic germs by involving holomorphic motions.

description: The IndustryPLAN tool targets the lacking middle ground between highly site-specific analyses of individual production facilities and generalized nationally aggregated analyses. The purpose of the IndustryPLAN tool is to open the black box of industry and provide a framework for developing sub-sector specific analyses on both a country-specific and European level. This is done by establishing both disaggregated industry energy demands for all countries of the EU and an extensive catalogue of potential mitigation measures for the future. Applying the energy efficiency first principle, the IndustryPLAN tool provides a framework for investigating the industrial energy sector in the context of the renewable energy transition. The user is provided with a flexible platform for developing future industry energy scenarios based on a range of potential energy efficiency measure, electrification measures, and hydrogen fuel shift measures. This report presents the scenarios resulting from the detailed analysis of the European industrial sector in the sEEnergies project. The scenario results provide the inputs necessary for representing the industry sector in further holistic energy system modelling in tools such as EnergyPLAN.

description: Wear is well known for causing material loss in a sliding interface. Available macroscopic approaches are bound to empirical fitting parameters, which range several orders of magnitude. Major advances in tribology have recently been achieved via Molecular Dynamics, although its use is strongly limited by computational cost. Here, we propose a study of the physical processes that lead to wear at the scale of the surface roughness, where adhesive junctions are formed between the asperities on the surface of the materials. Using a brittle formulation of the variational phase-field approach to fracture, we demonstrate that the failure mechanisms of an adhesive junction can be linked to its geometry. By imposing specific couplings between the damage and the elastic energy, we further investigate the triggering processes underlying each failure mechanism. We show that a large debris formation is mostly triggered by tensile stresses while shear stresses lead to small or no particle formation. We also study groups of junctions and discuss how microcontact interactions can be favored in some geometries to form macro-particles. This leads us to propose a classification in terms of macroscopic wear rate. Although based on a continuum approach, our phase-field calculations are able to effectively capture the failure of adhesive junctions, as observed through discrete Molecular Dynamics simulations.

description: The exclusive reactions $γp \to \bar K^0 K^+ n$ and $γp \to \bar K^0 K^0 p$ have been studied in the photon energy range 1.6--3.8 GeV, searching for evidence of the exotic baryon $Θ^+(1540)$ in the decays $Θ^+\to nK^+$ and $Θ^+\to p K^0$. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The integrated luminosity was about 70 pb$^{-1}$. The reactions have been isolated by detecting the $K^+$ and proton directly, the neutral kaon via its decay to $K_S \to π^+ π^-$ and the neutron or neutral kaon via the missing mass technique. The mass and width of known hyperons such as $Σ^+$, $Σ^-$ and $Λ(1116)$ were used as a check of the mass determination accuracy and experimental resolution. Approximately 100,000 $Λ^*(1520)$'s and 150,000 $ϕ$'s were observed in the $\bar K^0 K^+ n$ and $\bar K^0 K^0 p$ final state respectively. No evidence for the $Θ^+$ pentaquark was found in the $nK^+$ or $pK_S$ invariant mass spectra. Upper limits were set on the production cross section of the reaction $γp \to Θ^+ \bar K^0$ as functions of center-of-mass angle, $nK^+$ and $pK_S$ masses. Combining the results of the two reactions, the 95% C.L. upper limit on the total cross section for a resonance peaked at 1540 MeV was found to be 0.7 nb. Within most of the available theoretical models, this corresponds to an upper limit on the $Θ^+$ width, $Γ_{Θ^{+}}$, ranging between 0.01 and 7 MeV.

description: The Snowvision Project is an interdisciplinary, interagency effort aimed at advancing the study of Southeastern complicated stamped ceramics. Developed at the University of South Carolina, computer vision algorithms match 3D depth patterns on sherds to reconstructed paddle designs and to RGB (photo) images. Project depth and RGB images, along with robust metadata, are shared through the World Engraved website. Although Snowvision has been discussed in computer science and humanities publications, this poster introduces the project to the archaeological community for the first time. Project funding, publications, algorithms, website, student involvement, and research partnerships will be reviewed.

description: The Smoluchowsky equation for a system of interacting Brownian particles in a temperature gradient is derived from the Kramers equation by means of a multiple time-scale method. The interparticle interactions are assumed to be represented by a mean-field description. We present numerical results that compare well with the theoretical prediction together with an extensive discussion on the prescription of the Langevin equation in overdamped systems.

description: Quality of life is of great consequence with an aging population. Prior research has shown that social support and stress can have significant impacts on health-related quality of life (HRQoL), particularly for older adults with chronic illness. The current study advanced the literature by addressing the relations of functional social support and perceived stress to HRQoL in relatively healthy older adults. Participants were 137 community-dwelling, adults with no major, self-reported chronic illness (Mean age = 55 years, 53% male; 84% White). It was hypothesized that both lower levels of self-reported social support and higher levels of self-reported perceived stress would be associated with lower ratings of self-reported mental and physical HRQoL (after accounting for relevant covariates). Stress buffering effects were also explored. Results revealed that there were no significant relations of social support, perceived stress, or their interaction to physical HRQoL. However, lower social support scores and higher perceived stress scores predicted significantly lower ratings of mental HRQoL (p's < .05). There was no significant interaction of perceived stress and overall social support for mental HRQoL. In regards to the four social support subscales: there were no significant findings for belonging support; higher tangible support was associated with significantly better mental HRQoL (p < .05); and the deleterious relations of stress on mental HRQoL were significantly attenuated by appraisal support and self-esteem support (p's < .05). Overall, results indicate that various aspects of social support display important direct and stress-buffering relationships to mental HRQoL. Mechanistic and intervention research is needed to further elucidate these issues through additional longitudinal and experimental designs with a diverse population of older adults. Interventions focused on social relationships and stress management may offer a promising way to enhance quality of life in older adults.

description: The LOFAR Two-metre Sky Survey (LoTSS) will cover the full northern sky and, additionally, aims to observe the LoTSS deep fields to a noise level of ~10 microJy/bm over several tens of square degrees in areas that have the most extensive ancillary data. This paper presents the ELAIS-N1 deep field, the deepest of the LoTSS deep fields to date. With an effective observing time of 163.7 hours, it reaches a root mean square (RMS) noise level below 20 microJy/bm in the central region (and below 30 microJy/bm over 10 square degrees). The resolution is 6 arcsecs and 84862 radio sources were detected in the full area (68 sq. deg.) with 74127 sources in the highest quality area at less than 3 degrees from the pointing centre. The observation reaches a sky density of more than 5000 sources per sq. deg. in the central ~5 sq. deg. region. We present the calibration procedure, which addresses the special configuration of some observations and the extended bandwidth covered (115 to 177 MHz; central frequency 146.2 MHz) compared to standard LoTSS. We also describe the methods used to calibrate the flux density scale using cross-matching with sources detected by other radio surveys in the literature. We find the flux density uncertainty related to the flux density scale to be ~6.5%. By studying the variations of the flux density measurements between different epochs, we show that relative flux density calibration is reliable out to about a 3 degree radius, but that additional flux density uncertainty is present for all sources at about the 3 per cent level; this is likely to be associated with residual calibration errors, and is shown to be more significant in datasets with poorer ionosphere conditions. We also provide intra-band spectral indices, which can be useful to detect sources with unusual spectral properties. The final uncertainty in the flux densities is estimated to be ~10% for ELAIS-N1.

OLDER MEN'S KNOWLEDGE OF OSTEOPOROSIS BY RACE AND RISK FACTORS

Publisher: name: Maryland Shared Open Access Repository

description: Numerous studies have explored women's knowledge of osteoporosis.  Less commonly evaluated is men's osteoporosis knowledge.  The purpose of this study is to: 1) assess the psychometric properties of the combined Facts on Osteoporosis Quiz (FOOQ) and Male Osteoporosis Knowledge Questionnaire (MOKQ) and 2) investigate the predictors of men's knowledge of osteoporosis.  A sample of 1,518 men (mean age 78.6 years, S.D.=7.6; 3.6 % black), were surveyed about their knowledge of osteoporosis.  Overall knowledge was poor (mean=13.2 out of a possible 26, S.D.=5.9).  Rasch analysis found that the person reliability measure produced a Cronbach Alpha of 0.88.  The item reliability measure produced an item to measure correlation of -0.97.  The INFIT mean squares are all within the range of 0.5 to 1.5 logits indicating a good fit.  One question about the effect of walking on bone health had an OUTFIT statistic out of range (4.35).  Differential Item Functioning found that in general, the combined FOOQ/MOKQ preformed well across groups based on race, age, education, marital status, and residential location.  Question 3, ""most people gain bone mass after 30 years of age,"" had significant and substantial difficulty differences in race, age, and education groups.  To examine the predictors of men's knowledge of osteoporosis two multiple linear regressions were conducted.  The first examined the relationship of demographic variables and total known risk factors on knowledge.  The regression was statistically significant, F(6, 1511)=14.91, p
VAFB-2005-11: Archaeological and Native American Monitoring for the MCI Microcable Installation Project Vandenberg Air Force Base Santa Barbara County, California
Creators: name: Denardo, Carole A.
Year: 2005

description: This report presents the results of archaeological monitoring conducted by Garcia and Associates (GANDA) along the entire length of the Union Pacific Railroad (UPRR) passing through Vandenberg Air Force Base (AFB), a distance of approximately 30 miles. Between April 27 and June 30 2004, GANDA monitored ground disturbances associated with the installation of MCI's microduct and microcable.

The project purpose was to replace the obsolete fiber optic cable with a microduct and cable. It was possible to place the microduct inside the existing subsurface ductwork, followed by the insertion of microcable. Excavations of hand-dug shovel holes, referred to as "hand holes," occurred along the toe of the railroad slope in preset locations, approximately 10 to 15 feet off the centerline of the tracks. Where there were bends, breaks, or damage to the conduit, it was necessary to hand-excavate assist pits ("dig downs;" DD) of various dimensions and depths between hand holes.

Archaeological monitoring for this project established that most of the ground alongside the UPRR tracks has been previously impacted by previous railroad construction, maintenance and placement of utilities. In most instances, the disturbed cultural materials are associated with known sites. However, several locations along the tracks warrant further study, including the area surrounding DD 5a north of HH 13, DD 11, DD 14, and DD 12a. None of these artifacts is associated with recorded sites. In each case, the basalt bricks appear to be associated with railroad construction; it is possible that the bricks were placed in low-lying areas to elevate the level of the railroad tracks. The associated railroad cable in one location further suggests the use of basalt bricks in railroad construction. At DD 11, a layer of oily sand and cobbles was also noted in profile beneath the railroad tracks. Further studies in these locations could provide important information about railroad construction techniques.

In addition, a small fragment of amethyst glass found 20 feet west of DD 10 might be related to the historic railroad stop at Narlon (CA-SBA-2165H). Additional survey in this area could extend the site boundaries of CA-SBA-2165H.
Efficient Trajectory Planning for Multiple Non-holonomic Mobile Robots via Prioritized Trajectory Optimization

description: In this paper, we present a novel approach to efficiently generate collision-free optimal trajectories for multiple non-holonomic mobile robots in obstacle-rich environments. Our approach first employs a graph-based multi-agent path planner to find an initial discrete solution, and then refines this solution into smooth trajectories using nonlinear optimization. We divide the robot team into small groups and propose a prioritized trajectory optimization method to improve the scalability of the algorithm. Infeasible sub-problems may arise in some scenarios because of the decoupled optimization framework. To handle this problem, a novel grouping and priority assignment strategy is developed to increase the probability of finding feasible trajectories. Compared to the coupled trajectory optimization, the proposed approach reduces the computation time considerably with a small impact on the optimality of the plans. Simulations and hardware experiments verified the effectiveness and superiority of the proposed approach.

description: Uncovering the hidden regularities and organizational principles of networks arising in physical systems ranging from the molecular level to the scale of large communication infrastructures is the key issue for the understanding of their fabric and dynamical properties [1-5]. The ``rich-club'' phenomenon refers to the tendency of nodes with high centrality, the dominant elements of the system, to form tightly interconnected communities and it is one of the crucial properties accounting for the formation of dominant communities in both computer and social sciences [4-8]. Here we provide the analytical expression and the correct null models which allow for a quantitative discussion of the rich-club phenomenon. The presented analysis enables the measurement of the rich-club ordering and its relation with the function and dynamics of networks in examples drawn from the biological, social and technological domains.
