description: We have detected asymmetry in the symbiotic star CH Cyg through the measurement of precision closure-phase with the IONIC beam combiner, at the IOTA interferometer. The position of the asymmetry changes with time and is correlated with the phase of the 2.1-yr period found in the radial velocity measurements for this star. We can model the time-dependent asymmetry either as the orbit of a low-mass companion around the M giant or as an asymmetric, 20% change in brightness across the M giant. We do not detect a change in the size of the star during a 3 year monitoring period neither with respect to time nor with respect to wavelength. We find a spherical dust-shell with an emission size of 2.2+/-0.1 D* FWHM around the M giant star. The star to dust flux ratio is estimated to be 11.63+/-0.3. While the most likely explanation for the 20% change in brightness is non-radial pulsation we argue that a low-mass companion in close orbit could be the physical cause of the pulsation. The combined effect of pulsation and low-mass companion could explain the behaviour revealed by the radial-velocity curves and the time-dependent asymmetry detected in the closure-phase data. If CH Cyg is a typical long secondary period variable then these variations could be explained by the effect of an orbiting low-mass companion on the primary star.

I ricercatori del Caltech spiegano perché una densa nube vicino al centro galattico, che sulla carta dovrebbe essere una fucina di nuove stelle, ne produca in realtà pochissime. Ruota su se stessa troppo velocemente, e la materia non ha tempo di stabilizzarsi.

Un team di astronomi britannici ha scovato la più grande struttura mai osservata nel cosmo, un gruppo di quasar che misura 4 miliardi di anni luce. La scoperta sembra contraddire il Principio Cosmologico, per cui strutture così grandi non dovrebbero esistere.

description: What kind of lattice Hamiltonian manifestly has an ordered state with spontaneous orbital currents? We consider interacting spinless fermions on an array of square plaquettes, connected by weak hopping; the array geometry may be a 2 x 2L ladder, a 2 x 2 x 2L "tube", or a 2L x 2L square grid. At half filling, we derive an effective Hamiltonian in terms of pseudospins, of which one component represents orbital currents, and find the conditions sufficient for orbital current long-range order. We consider spinfull variants of the aforesaid spinless models and make contact with other spinfull models in the literature purported to possess spontaneous currents.

description: The eigenvalues of a matrix polynomial can be determined classically by solving a generalized eigenproblem for a linearized matrix pencil, for instance by writing the matrix polynomial in companion form. We introduce a general scaling technique, based on tropical algebra, which applies in particular to this companion form. This scaling, which is inspired by an earlier work of Akian, Bapat, and Gaubert, relies on the computation of "tropical roots". We give explicit bounds, in a typical case, indicating that these roots provide accurate estimates of the order of magnitude of the different eigenvalues, and we show by experiments that this scaling improves the accuracy (measured by normwise backward error) of the computations, particularly in situations in which the data have various orders of magnitude. In the case of quadratic polynomial matrices, we recover in this way a scaling due to Fan, Lin, and Van Dooren, which coincides with the tropical scaling when the two tropical roots are equal. If not, the eigenvalues generally split in two groups, and the tropical method leads to making one specific scaling for each of the groups.

description: Coalescing massive black hole binaries are produced by the mergers of galaxies. The final stages of the black hole coalescence produce strong gravitational radiation that can be detected by the space-borne LISA. In cases where the black hole merger takes place in the presence of gas and magnetic fields, various types of electromagnetic signals may also be produced. Modeling such electromagnetic counterparts of the final merger requires evolving the behavior of both gas and fields in the strong-field regions around the black holes. We have taken a step towards solving this problem by mapping the flow of pressureless matter in the dynamic, 3-D general relativistic spacetime around the merging black holes. We find qualitative differences in collision and outflow speeds, including a signature of the merger when the net angular momentum of the matter is low, between the results from single and binary black holes, and between nonrotating and rotating holes in binaries. If future magnetohydrodynamic results confirm these differences, it may allow assessment of the properties of the binaries as well as yielding an identifiable electromagnetic counterpart to the attendant gravitational wave signal.

description: We present a method to measure the resonance transitions between the gravitationally bound quantum states of neutrons in the GRANIT spectrometer. The purpose of GRANIT is to improve the accuracy of measurement of the quantum states parameters by several orders of magnitude, taking advantage of long storage of Ultracold neutrons at specula trajectories. The transitions could be excited using a periodic spatial variation of a magnetic field gradient. If the frequency of such a perturbation (in the frame of a moving neutron) coincides with a resonance frequency defined by the energy difference of two quantum states, the transition probability will sharply increase. The GRANIT experiment is motivated by searches for short-range interactions (in particular spin-dependent interactions), by studying the interaction of a quantum system with a gravitational field, by searches for extensions of the Standard model, by the unique possibility to check the equivalence principle for an object in a quantum state and by studying various quantum optics phenomena.
Knowledge Management Concepts For Training By Project An observation of the case of project management education

description: Project management education programmes are often proposed in higher education to give students competences in project planning (Gantt's chart), project organizing, human and technical resource management, quality control and also social competences (collaboration, communication), emotional ones (empathy, consideration of the other, humour, ethics), and organizational ones (leadership, political vision, and so on). This training is often given according a training-by-project type of learning with case studies. This article presents one course characterized by a pedagogical organization based upon Knowledge Management (KM) concepts: knowledge transfer and construction throughout a learning circle and social interactions. The course is supported by a rich and complex tutor organization. We have observed this course by using another KM method inspired from KADS with various return of experience formalized into cards and charts. Our intention is, according to the model of Argyris and Schön (Smith, 2001), to gain feedback information about local and global processes and about actors' experience in order to improve the course. This paper describes precisely the course (pedagogical method and tutor activity) and the KM observation method permitting to identify problem to solve. In our case, we observe problem of pedacogical coordination and skills acquisition. We propose to design a metacognitive tool for tutors and students, usable for improving knowledge construction and learning process organisation

description: We investigated the association of coping with quality of life (QoL) among parents of children with chronic illnesses, particularly inherited metabolic diseases (IMD); and whether coping may modify the association between caregiving complexity and parental QoL. In project 1, we systematically reviewed studies of parents of children with chronic illness. Among 10 eligible studies, we identified some evidence that adaptive coping strategies were positively associated with parental psychological QoL. In project 2, we analyzed data from a crosssectional mailed Canadian survey of parents of children <12 years of age with IMD. Among 113 respondents, greater emotion-focused coping was associated with lower mental QoL (all parents) and higher depressive symptoms (parents of children >=5 years). Analysis of significant interactions between coping and caregiving complexity did not reveal clear trends. Understanding the association of parental coping with QoL may help to inform interventions to promote parental health as part of family-centred care.

description:
Using the Productivity Environmental Preference Survey (PEPS) and a self­ designed demographic survey, this study assessed the learning styles of students enrolled in a NATA approved graduate athletic training education program and compared the relationship between learning style preferences and the demographic characteristics of the graduate students. The PEPS survey is a 100-item Likert scale learning style inventory relating to 20 learning style elements of 4 domains: environmental, emotional, sociological, and physical. As part of the demographic research, participants completed measures assessing geographic, family, educational, and personal information.

Participants were 163 (55 men, 108 women) graduate athletic training students from eleven of the thirteen CAAHEP-accredited graduate athletic training programs. The demographic survey and PEPS survey were mailed to the program directors of the various institutions with specific directions for distribution to the students. Correlations were calculated between learning styles and demographic data using Pearson Chi-Square, one-way ANOVA, and t-tests. The learning style preferred most on the PEPS included structure (59.11 ± 6.96) and afternoon learning (58.05 ± 10.73). Some significant (p<0.05) cross-tabulations included persistence with race (p=0.01), reputation (p=0.008), application status (p=0.02), region lived most (p=0.002), and undergraduate school region (p=0.004); late morning with type of program (p=0.01) and location (p=0.03);alone/peers with class level (p=0.005); authority figures with class level (p=0.002); several ways with class level (p=0.01); time of day with class level (p=0.01); structure with money (p=0.006), certification status (p=0.03), and curriculum (p=0.008); and kinesthetic with reputation (p=0.04). Both undergraduate (F2,20=3.010, p=0.05) and graduate (F2,20=4.819, p=0.009) GPA's were influenced by light.

The results of this study demonstrate that some of the demographic characteristics influence learning style preferences of graduate athletic training students. While some of the results are unexplainable, two consistent findings regarding athletic training education are the preference for a structured learning environment and the preference for afternoon learning, specifically for first-year graduate athletic training students. In general, more research needs to be conducted about the demographic characteristics of graduate athletic training students, and further research should investigate how athletic training improves when educators teach according to student learning style preferences.

description: We report the results of a 3-weeks multi-wavelength campaign on the flat spectrum radio quasar 3C 273 carried out with the AGILE gamma-ray mission, covering the 30 MeV -50 GeV and 18-60 keV, the REM observatory (covering the near-IR and optical), Swift (near-UV/Optical, 0.2-10 keV and 15-50 keV), INTEGRAL (3 - 200 keV) and Rossi XTE (2-12 keV). This is the first observational campaign including gamma-ray data, after the last EGRET observations, more than 8 years ago. Our study was carried out using simultaneous light curves of the source flux from all the involved instruments, in the different energy ranges, in search for correlated variability. Then a time-resolved SED was used for a detailed physical modelling of the emission mechanisms. The source was detected in gamma-rays only in the second week of our campaign. We found indication of a possible anti-correlation between the emission at gamma-rays and at soft and hard X-rays, supported by the complete set of instruments. Instead, optical data do not show short term variability. Only in two EGRET observations (in 1993 and 1997) 3C 273 showed intra-observation variability in gamma-rays. The SED with almost simultaneous data, partially covers the regions of the synchrotron emission, the big blue bump, and the inverse-Compton. The soft X-ray emission is consistent with combined SSC and EC mechanisms, while hard X and gamma-ray emissions are compatible with EC from thermal photons of the disk. The time evolution of the SED is well interpreted and modelled in terms of an acceleration episode of the electrons population, leading to a shift in the IC peak towards higher energies.

description: We test the truncated disc models using multiwavelength (optical/UV/X-ray) data from the 2005 hard state outburst of the black hole SWIFT J1753.5-0127. This system is both fairly bright and has fairly low interstellar absorption, so gives one of the best datasets to study the weak, cool disc emission in this state. We fit these data using models of an X-ray illuminated disc to constrain the inner disc radius throughout the outburst. Close to the peak, the observed soft X-ray component is consistent with being produced by the inner disc, with its intrinsic emission enhanced in temperature and luminosity by reprocessing of hard X-ray illumination in an overlap region between the disc and corona. This disc emission provides the seed photons for Compton scattering to produce the hard X-ray spectrum, and these hard X-rays also illuminate the outer disc, producing the optical emission by reprocessing. However, the situation is very different as the outburst declines. The optical is probably cyclo-synchrotron radiation, self-generated by the flow, rather than tracing the outer disc. Similarly, limits from reprocessing make it unlikely that the soft X-rays are directly tracing the inner disc radius. This is seen more clearly in a similarly dim low/hard state spectrum from XTE J1118+480. The very small emitting area implied by the relatively high temperature soft X-ray component is completely inconsistent with the much larger, cooler, UV component which is well fit by a truncated disc. We speculate on the origin of this component, but its existence as a clearly separate spectral component from the truncated disc in XTE J1118+480 shows that it does not simply trace the inner disc radius, so cannot constrain the truncated disc models.

description: The recently developed new algorithm for computing consistent initial values and Taylor coefficients for DAEs using projector-based constrained optimization opens new possibilities to apply Taylor series integration methods. In this paper, we show how corresponding projected explicit and implicit Taylor series methods can be adapted to DAEs of arbitrary index. Owing to our formulation as a projected optimization problem constrained by the derivative array, no explicit description of the inherent dynamics is necessary, and various Taylor integration schemes can be defined in a general framework. In particular, we address higher-order Padé methods that stand out due to their stability. We further discuss several aspects of our prototype implemented in Python using Automatic Differentiation. The methods have been successfully tested on examples arising from multibody systems simulation and a higher-index DAE benchmark arising from servo-constraint problems.

description: Periodically structured materials can sustain both optical and mechanical excitations which are tailored by the geometry. Here we analyze the properties of dispersively coupled planar photonic and phononic crystals: optomechanical crystals. In particular, the properties of co-resonant optical and mechanical cavities in quasi-1D (patterned nanobeam) and quasi-2D (patterned membrane) geometries are studied. It is shown that the mechanical Q and optomechanical coupling in these structures can vary by many orders of magnitude with modest changes in geometry. An intuitive picture is developed based upon a perturbation theory for shifting material boundaries that allows the optomechanical properties to be designed and optimized. Several designs are presented with mechanical frequency ~ 1-10 GHz, optical Q-factor Qo > 10^7, motional masses meff 100 femtograms, optomechanical coupling length LOM < 5 microns, and a radiation-limited mechanical Q-factor Qm > 10^7.

The quantum capacity of channels with arbitrarily correlated noise

description: We study optimal rates for quantum communication over a single use of a channel, which itself can correspond to a finite number of uses of a channel with arbitrarily correlated noise. The corresponding capacity is often referred to as the one-shot quantum capacity. In this paper, we prove bounds on the one-shot quantum capacity of an arbitrary channel. This allows us to compute the quantum capacity of a channel with arbitrarily correlated noise, in the limit of asymptotically many uses of the channel. In the memoryless case, we explicitly show that our results reduce to known expressions for the quantum capacity.

description: Geospatial data is getting bigger and more difficult to analyse. Satellites, drones, vehicles, social networks, mobile devices, cameras, etc. generate vast amount of (open) geospatial data. Numerous methods and (open-source) applications have been developed to enable discovery, delivery, analysis, and visualization of geospatial data. However, large and complex geospatial data sets are difficult to handle using conventional systems and methods. Data processing and analysis tasks are time consuming, sometimes even not possible, if they are performed on laptops or local workstations. Solutions require expert know-how and infrastructure. Local and regional studies with medium size data can be done faster by parallel computing on a workstation. Machine learning and AI studies with medium size data require special processing units (e.g., GPU/TPU) due to computational complexity. National, continental, and global studies with big data require distributed computing on a computing cluster due to computational complexity and/or large volume of data. Cloud computing is on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Computing is moving to the Cloud, so is geocomputing. Developments in infrastructure, both hardware and software, gave a big push to data processing and analysis capabilities. Scalable and affordable computing is available through open-source systems that allow computing clusters on commodity hardware, and proprietary cloud-based data storage and computing services. However, it is challenging to choose the right solution(s) depending on the nature of geospatial data and analysis needs. Using the solutions usually requires a transition in modus operandi.

Giant anomalous Hall resistivity of the room temperature ferromagnet Fe3Sn2 - a frustrated metal with the kagome-bilayer structure

description: We have investigated magnetic and transport properties of the {\it kagomé-bilayer} ferromagnet Fe$_{3}$Sn$_{2}$. A soft ferromagnetism and a large anomalous Hall effect are observed. The saturated Hall resistivity of Fe$_{3}$Sn$_{2}$ is 3.2 $μΩ$cm at 300 K, which is almost 20 times higher than that of typical itinerant-ferromagnets such as Fe and Ni. The anomalous Hall coefficient $R_{\rm s}$ is 6.7$\times10^{-9}$ $Ω$cm/G at 300 K, which is three orders of magnitude larger than that of pure Fe. $R_{\rm s}$ obeys an unconventional scaling to the longitudinal resistivity, $ρ_{xx}$, of $R_{\rm s} \propto ρ_{xx}^{3.3}$. Such a relationship cannot be explained by the skew and/or side-jump mechanisms and indicates that the origin of the anomalous Hall effect in the frustrated magnet Fe$_{3}$Sn$_{2}$ is indeed extraordinary.
